Smartphones and Battery Life

Since I’m on the comparison of Android and iOS kick I might as well talk about battery life. Most reviews of high-end Android devices knock the reviewed device for having poor battery life. I know the biggest hit against the Evo 4G is it’s battery life. My iPhone has had great battery life compared to my Evo giving me two days instead of one on a single charge (I count battery life in number of days before needing to recharge the phone, my Treo 755p got roughly three days).

There are many things to consider when comparing battery life including the storage capacity of the battery. The other major factory in battery life is the operating system and applications. The iPhone’s multi-tasking capabilities are… poor to say the least. If you want to run something in the background that Apple hasn’t provided a specific service for you have up to 10 minutes (the iPhone allows an application to run for 10 minutes in the background before suspending it).

Android on the other hand allows true multi-tasking. Any application is spawn a service that can run in the background even when the main application is no longer being displayed. This gives Android far more flexibility. Allowing real multi-tasking can also take a toll on the battery life as a runaway process can run the CPU at 100% and turn your battery life into a mere couple of hours. Personally I find the tradeoff worth it as any application that slaughters your battery life is poorly written and really the fault of the developer, not the device.

What I blame Android for is it’s poor built-in battery life reporting tool. On the Evo if you go under Settings->About Phone there is an item called Battery Life. This little application tells you the rough percentage of battery charge remaining and what has been using the battery life. This reporting tools does an abysmal job unfortunately.

I still carry my Evo around and use it as a portable Wi-Fi hotspot (which it works great as). I noticed when I returned home last night the phone was reporting the battery was almost completely dead. Usually this means some application is going crazy either pulling down data or racking up the CPU. A simple reboot of the phone generally takes care of this but I’m more of a curious person and wanted to know exactly what process was draining my battery.

Well the battery usage reporting tool did say it was the Android system that was using a majority of my power… of course that’s a catchall for every application on the device. The battery usage tool lumps every application under the Android system category and does not breakdown by individual application. In fact it’s not possible with Android’s built-in battery usage tool to see how much CPU time (and thus a rough estimation of battery life) an individual application has used. This makes finding the rough process difficult if not impossible.

I really like the fact Android has true multi-tasking and accept the responsibility that comes with such flexibility. But I’d also like a mechanism to see how much power each individual application is sucking down. Having such information would allow me to determine if an app I downloaded was poorly written and remove it. As it sits now you practically have to download an app, test it for a day, see the impact on battery life, and hope it doesn’t screw up later down the road.

GSM vs. CDMA

It’s almost been a month of using the iPhone and thus AT&T. AT&T (along with T-Mobile) is a GSM network while Sprint (along with Verizon) is a CDMA network. For the end user the difference isn’t very noticeable in most cases although if you’re in the Midwest you’ll likely noticed better coverage with CDMA.

GSM has two major advantages over CDMA for the end user. The first advantage is the fact CDMA phones use a SIM card which can be taken out of one phone and inserted into another (so long as the other phone will work on the first phone’s network). If you want to swap CDMA phones the process is generally more difficult (for example on Sprint you need to log into your Sprint account online and enter in a series of numbers on the new phone). The second advantage is the fact on a GSM phone you can use both the voice capabilities and data at the same time. With a CDMA phone if you’re talking to somebody you can’t use data and if you want to use data you can’t call somebody. Even though there is no reason for this Sprint has even locked the Evo 4G into not allowing voice usage and 4G data usage at the same time (with 3G it’s a limitation of the hardware/protocol while with 4G the restriction is purely artificial).

Well it dawned on me when somebody called me and asked a question that required I look something up. I told them, “Hold on a second I’ll look it up and call you ba… wait hold just a second” and discovered the wonders of a phone that can use voice and data at the same time. Huge advantage.

I also learned that there apparently isn’t any additional cost to use call forwarding on AT&T, just just consumes your minutes. That means when I travel back home (where I have no AT&T coverage but have Sprint coverage) I can set my iPhone to forward calls to my Evo without having to rack up Sprint’s 20 cents a minute for forwarding calls charge.

There certainly are downsides to AT&T (their data plan is fucking horrible compared to Sprint’s) but there are also some upsides.

iOS and Android Compared

I’ve had some time with iOS on my iPad and Android on my Evo 4G. Obviously there are a lot of differences and I figure I might as well record some of them.

I know there is a lot of debate on whether Android is open or not. Personally I’ve complained several times about how locked down Android is on most phones. After working with iOS for a while I can say for a fact that iOS is a veritable prison compared to Android. Although Android can’t do a lot on a phone that hasn’t been rooted it isn’t tied to a desktop computer.

Generally I don’t have to connect my Evo to my computer unless I need to get some files off of my desktop. I can download most files onto my phone from my phone. The iPad is far different in that it requires all files be downloaded through iTunes. You can’t do a damned thing on an iOS device without a desktop running iTunes. That’s pretty restrictive if I do say so myself.

A big part of this problem comes from the lack of a universal file storage area on iOS devices. On Android devices any files stored on an external media (think SD card) are readable by any application. This means if you use the browser to download a file onto an SD card you can open said file with another program. This can’t be done on an iOS device. If you want to download a file and open it in another program you must download that file on your desktop and transfer the file to your iOS device via iTunes. This is probably the largest limitation in iOS devices.

Another thing that keeps the iOS platform locked down is the inability to install application from a source outside of iTunes. If apple doesn’t approve an application you simply can’t install it. On most Android devices you can side load applications. This means you’re not at Google’s mercy when it comes to applications you can install. Once against this is a pretty severe restriction to place on a device.

One thing that Android has that if find lacking in iOS are widgets. I never thought I’d like widgets so damned much but honestly they are very nice to have. My home screen on my Evo displays the time, weather, upcoming appointments, and my todo list. To see these I just have to turn my phone on. On my iPad I’d have to open a weather application, the calendar application, and a todo application one after another. Widgets make getting specific information quickly easy.

The final mistake made in iOS was the notification system. When an application sends a notification a dialog box pops up and must be dealt with before returning to whatever you were doing before being interrupted. Android has a much nicer system where an icon appears in the upper left-hand corner of the screen and you can read the notification but running your finger from the top of the screen down. Doing this brings down the notification area with a list of all current notifications that haven’t been dealt with. Neither is as intuitive as WebOS’s notification system though.

Now that I’ve bitched about iOS let me focus on the things it does well. The mos notable difference between iOS and Android is the interface. Apple has a long tradition of having consistent and easy to use interfaces. That tradition holds true on iOS. All the included applications have intuitive interfaces which are easy to navigate. Navigation is done consistently in the included applications as well. For instance if I open and application, flip to a new form, and want to flip back I can rest assured that the button to return me to my previous screen will be in the upper left-hand corner of the new form.

Android is the opposite of this. The user interface in Android is inconsistent at best although it has been improving over the various versions. Hell there isn’t even a unified e-mail application included in Android. If you use GMail then you can use Google’s GMail application otherwise you are stuck with the other stock Android e-mail application. These two applications don’t even work in similar manners. For example GMail has a threaded interface with the controls for replying at the top of the e-mail header. The other e-mail application has no conversation threading and replying is done via two buttons at the bottom of the screen. I haven’t a clue what Google was thinking with this but it’s not done properly.

Although it hasn’t been released for the iPad yet I’ve played with iOS’s multitasking via emulators and devices at the Apple store. I’ve mentioned that the back end mechanism for doing multitasking in iOS is poorly implemented but the interface for switching between running applications is better than the standard Android mechanism. In iOS tapping the home screen twice brings up a list of “running” applications (application still in memory but not using CPU time). Every application that’s still in memory will be listed and can be selected by tapping on the application’s icon. Android’s mechanism is… inconsistent. Holding down the home button will bring up a list of the last eight used applications which is tedious (it’s roughly a one second button hold which doesn’t sound long until you’re trying to quickly navigate between three applications). Some applications are good enough to place an icon in the notification bar which makes navigating back to that applications as easy as opening the notification area and tapping on said icon. One again neither are as intuitive and quick as WebOS but this post isn’t about how to do an interface correctly.

If there is one thing Apple is good at it’s polish. I can’t never say that enough because it’s honestly very true. Most things under iOS just scream polish job. The interface is consistent, animations always run smoothly, and shit happens when it’s supposed to (when I rotate my iPad the screen rotates instantly, sometimes my Evo requires a few violent shakes to get the screen to notice I changed the device’s orientation). Everything on iOS is kept simple and uncluttered which I really appreciated on a mobile device.

The bottom line is you have a choice; a very pretty and well run prison or a village to roam where little was planned in accordance with other parts. Frankly Android still wins in my book because I can actually have a device that doesn’t need to be tethered to my computer at any time. On the other hand using iOS is a very pleasant experience and I can know with some matter of certainly what will happen when I do something.

Just as Soon as It Becomes Useful

The iPad is actually useful as a media player because VLC was allowed in the Apple Store. Sadly it seems the VLC Media Player is going to be removed due to the incompatibility between Apple’s de factor Digital “Rights” Management (DRM) and the GNU Public License (GPL) which VLC is released under.

One of the problems with the iOS App Store is the mandatory use of DRM. This violates several open source licenses which assures many projects will not be made available for iOS devices. Thankfully Android doesn’t have this problem and thus open source applications can be released DRM-free.

Additionally with the removal of VLC the iOS platform will lose the ability to play 99% (possible exaggeration) of video files out there. Thus the iPad’s advantage as a media play will be flushed right down the toilet.

NOOKcolor

I guess I didn’t mention this day of release but Barnes and Nobel have released the newest version of their Nook (Nook, nook, NOOK, I’m not sure what the fuck the proper capitalization is for this product) e-reader, the NOOKcolor (capitalized as it appears on their site).

It should be obvious why I didn’t get all excited and post this thing day of release, it’s a yawner. Basically it’s an Android tablet. Yup, that’s really it. It has absolutely no e-ink display instead opting for a single touchscreen LCD. So it’s an lighter, smaller, and cheaper iPad running Android (you can’t actually access any of the sweet Android goodness at this point from my understanding).

Frankly this thing is a huge let down. Although I assumed the NoOkCoLoR (now I’m just going to fuck with the name) would simply be an e-reader with an LCD screen I was secretly hoping it would jump ahead of the Kindle by using a color e-ink display. Apparently Barnes and Nobel decided to take the low road instead and just simply make a tablet which there are only about a million of coming out at the moment.

Android Voice Commands

I think I’ve found a killer feature in the Android operating system, voice commands. First let me clarify that Android is the first operating system I’ve ever used that has voice recognition that actually works. I’d say the voice recognition software on Android is accurate with what I say roughly 90% of the time. Yes I realize 10% rate of failure is pretty big but honestly for voice recognition it’s pretty friggin’ phenomenal.

Voice commands are activated on the Evo 4G by holding down the search button. When held down a little dialog box will appear asking you to speak your command and the phone will act from there. My two favorite commands are “direction to” and “send text.” If you say, “direction to 1234 South North Street Podunk Minnesota” the phone will open Google Maps and plot directions from your current location to 1234 South North Street Podunk, MN.

The “send text” command works in the same fashion. When you say, “send text to Fictional Person I’ll be there in five minutes period” the phone will display a text message to Fiction Person that says, “I’ll be there in five minutes.” All you have to do after that is tap the send button and away it goes.

That’s one thing you have to realize, punctuation must be spoken. The speech recognition can’t predict when you want to add a period or question mark so you have to speak them. It’s kind of a pain in you want the work period written out but it works correctly nine times out of ten.

I’m simply blown away by the voice command feature and how well it works.

So Much for Palm OS Emulation

Before getting my Evo 4G I had a Palm Treo 755p, before that a 700p, before that a Palm T|X, before that… well you get the idea. I was (and still am) a huge fan of the original Palm OS. That’s one of the reasons I was so excited for the Palm Pre, it had a high quality Palm OS emulator included with it.

Alas it seems Palm has removed the Palm OS ROM from the next version of their OS which renders MotionApps emulator worthless (since Palm OS was never open sourced we’re at the mercy of Palm to deliver a ROM for emulation). What excitement I had for WebOS 2 (what is a lot although the hardware that has been revealed is pretty piss poor) is quickly drying up. Since WebOS has the fewest available applications (compared to iOS and Android) the Palm OS emulator was used to fill in the gaps (for instance if you needed a VPN client you had to install it in Classic). Now it seems that option has been put to bed.

The iPad

Due to completion of a fortuitous side job (here’s an interesting fact, knowing assembly language for Freescale based microcontrollers can be extremely profitable) I found myself with a good chunk of extra money in my pocket this month. I’m sure anybody who read the title can figure out where this post is going, I used some of that money to purchase an iPad.

OK just let out your gasps of surprise and outrage, I’ll wait…

Still going?

Done now? Good. I’m sure you’re wondering how after all my bitching, whining, and complaining about Apple’s mobile products why I’d get an iPad. In all honesty for two reasons. First the iPad fulfills a few needs I have. Second as much as I hate the Apple store, iOS development is something I should know how to do as it’s incredibly popular.

First my needs. I’ve been lusting after a tablet device running a mobile operating system for a very long time. A small and portable device that is big enough to do real web browsing on appeases to me. Likewise It would be nice to have something besides my big honking laptop when traveling. I love my laptop but 15″ doesn’t fit on those plane seat-mounted tables very well. Mostly I wanted a mobile media device.

Why not wait for an Android tablet? Because the only decent one announced so far has a 7″ screen is is tied to various cell phone carriers. I wanted a 10″ screen, simple as that. In addition to that I also wanted a Wi-Fi only device that I didn’t have to pay a monthly fee for. The iPad does all of that and any competition won’t be out for quite some time.

This post is mostly going to be about my initial thoughts on the device. To make things more interesting I’m posting this using my iPad with an paired Bluetooth keyboard (yes this is an awesome feature, a tablet that can use a standard Bluetooth keyboard). Because I’m in a positive mood I’ll start with the things I like about the iPad so far.

To begin let me talk battery life. The batter life on the iPad is phenomenal. I mean that. I used the device for roughly five hours last night and was trying to use every battery draining feature I could come across. Out of the box the iPad had a 90% charged battery and by the end of the five hours it was still above 60%. This includes web browsing, playing some games, watching YouTube videos, and having the screen running for almost the entire time. In fact I set the auto-lock timeout to 15 minutes to ensure the screen wouldn’t be off very often just to beat on the battery. Color me impressed.

Next up I want to just say when it comes to polish Apple knows their stuff. The interface on the iPad runs smoothly. There is no lag when scrolling web pages pages, zooming into pictures, or rotating the screen. It all happens instantly and smoothly. In order to get my Evo to rotate the screen I sometimes have to shake it in an exaggerated manner to finally get it to the orientation I want. The iPad also has a switch to lock the orientation so rotating the device won’t cause the screen to re-adjust. Videos, even HD ones, play without so much as a stutter. I used VLC to play a bunch of television shows I have and at no point did I notice any slow down. Everything feels complete and well thought out which is Apple’s modus operandi.

As a media and web device the iPad is great. Of course now it’s time to rattle off when I don’t like so far on the iPad. The biggest drag is the fact that you have this nice, big, and powerful device with wireless network access and you can’t do a damned thing without plugging it into a computer (and the iPad doesn’t charge off of my USB ports, just a small niggle to irritate you). Now only do you have to plug it into a computer, but a computer that has iTunes installed. Getting data onto the iPad is reminiscent of the old Palm OS and Pocket PC days.

Let’s say I want to put a movie onto my Evo. To accomplish this goal I plug my Evo into any computer with a standard USB cable, turn on drive mode, and copy the files to the Evo’s SD card. It’s simple, straight forward, and works very well. Now let’s say I want to put a movie onto my iPad. To accomplish this goal I have to plug my iPad into a computer with iTunes, tell iTunes what movies I want to upload and what application to use those movies on (more on that in a bit), and finally click the sync button and wait. I mention the waiting part because if you try to use the iPad during a sync operating it seems to stall until you lock the screen again. This could be user error as this is an initial thoughts post instead of an actual review.

I mentioned that you have to tell iTunes what application to upload the movie to. Android has a nice setup where anything on external storage is readable by any application on the device. If you have an application that you want to keep the data private one you store that data in the device’s memory which is secure form being read by any other application. iOS lacks the first mentioned mechanism as there is no universal file storage area. Every file on the device is usable by only the single program you copied it to. This means if you want a photo uploaded for use with two applications (let’s say two photo editors that do different things) you need to copy the file onto the device twice. I’m going to be honest here, this is stupid. I understand the desire to sandbox applications, that’s a good thing, but at least have a mechanism for sharing data between applications.

Let me use another example. There is a website I frequent that you probably haven’t heard of. This site has a ton of free PDFs for downloading and reading. On my Evo I just select the PDF, download it to the SD card, and open it with my read of choice. On the iPad I… swear up a storm because I can’t just download a file and open it with another application. When downloaded that PDF is locked to Safari so it can’t be read in another application. I order to get that PDF into a reader application I have to either download it on my desktop and upload the file via iTunes, highlight and copy the URL of the PDF document and then hope the reader application has the ability to download PDF files, or read the PDF in Safari.

To boot the ability to sync with online services just isn’t well implemented. When I add a Google account to my Android phone everything on that account can be synced. This means once setup my phone will automatically pull down my e-mail, contacts, and calendar. The only way to do this on the iPad is using an Exchange server. Adding a Google account only grabs the e-mail. To get your Google stored contacts you have to have Address Book on your Mac sync with your Google account and then use iTunes to sync Address Book with your iPad. The same goes for your Google calendar. I realize that Apple sells their MobileMe servier but frankly if you want to have a device this day an age it should sync with most major online services. There is no reason this day and age to require me to plug one of my portable device into another computer in order to get my contacts and calendar. Fucking ridiculous.

Since I mentioned reading let me get to another task the iPad does poorly. I downloaded the Kindle application and synced Old Man’s War to the iPad. As a reader the iPad sucks. Plain and simple. I don’t like reading on back lit screens now that I’ve experienced the wonders of e-ink. There is no way I could ever go back when it comes to reading novels. On top of that the iPad is very heavy compared to the Kindle meaning you arms are going to tire of holding the iPad for any extensive amount of time. So yeah the Kindle is staying.

One thing I never thought I’d miss on a device is the Android back button. It’s hard to realize how often you just need to go back to a previous screen until you’ve had a device with a dedicated back button and then used a device that doesn’t. It’s a small thing but every time I want to go back in an application I generally have to tap a button at the top of the screen. I’ll admit it’s not a big deal just a little something I noticed.

Overall I like the iPad for the reasons I purchased it. It’s a far more portable device than my laptop and handles media very well. Until iOS 4 becomes available for the iPad I’m not going to give it an serious consideration as a communication device because I need multi-tasking for an IRC client. The iPad also oozes polish and user experience. It’s seriously fast and the interface always runs smoothly. As a phone operating system I don’t think I could get by with it. I’m too used to having a phone that isn’t dependent on being connected do another computer.

The bottom line is I like the iPad for what I bought it for but do not line iOS as anything outside of a media operating system (so far, maybe that will change as I find new things). There are also some seriously fun games for the iPad… just throwing that out there.

Apple’s New Annoucements

Yesterday Apple held their Back to the Mac event. This is the event of the year where they release things that I actually get excited about (I know I give their mobile devices a lot of heck on here but I really do like their computers). There were several announced products; some I’m excited for and some that I could care less about.

First the stuff I don’t care about. They announced a new version of iLife and they are creating a FaceTime client for OS X. I don’t really use iLife and frankly I don’t need people to see me when I’m talking to them. With those two things out of the way let’s talk about the stuff that actually matters (to me).

The next version of OS X was announced. This one is keeping with the big cat naming scheme an has been titled Lion. This will be the eight version of OS X (they started with 10.0 and are now on 10.7). Apple made no qualms about saying 10.5 would be the last really big update for quite some time. 10.6 was mostly a maintenance update with a few new features and 10.7 seems to be the same thing. Apple is tossing in some iOS features into 10.7 and that seems to be the main thing. I’m sure there will be a lot of under the hood fixes to boot.

For quite some time Apple has had the MacBook Air. The Air was the product that I never really understood where it fit in because it was expensive and had a 13″ in screen which the MacBook and MacBook Pro line both had. Needless to say outside of thickness the Air really had nothing going for it. I have to admit the new MacBook Air models Apple announced yesterday actually seem to have enough advantages to be worth introducing.

My main laptop is a 15″ MacBook Pro. A 15″ screen certainly isn’t the most portable screen size on the planet but 90% of the time I have my laptop on a desk and really only need the portability to go from point A to point B. I like having a large work space and I find a 15″ screen to be the perfect combination of portability and work space. The problem comes when I’m in small and cramped areas like airplanes. Having a 15″ monstrosity on one of those dinky seat mount tables on an airplane isn’t pleasant. If the guy sitting in the chair forward of you leans back there is a good chance he’ll pinch the top of your screen which could very well damage it.

The new MacBook Air comes in two screen sizes; the familiar 13″ model which I still find kind of pointless and the small 11″ model which I find great. Of course the price of the 11″ model hovers around the $1,000 which is pretty damned expensive when you consider you can get a netbook for roughly one third of that price. There isn’t much to justify this additional cost beyond the Air has an Solid State Drive (SSD) drive that is supposedly “instant on” (which generally means almost instant) and the screen resolution is 1366×768 which is pretty damned good for an 11″ display. One of the things I really like about Apple’s laptops is the screen real estate. I was looking through some other laptops the other day and found most 15″ model laptops that are a decent price have a screen resolution of 1366×768. That’s not even usable in my opinion. So having an 11″ screen with a resolution equal to that of most cheaper 15″ laptops is pretty damned impressive.

Honestly I can’t justify plunking down $1,000 for a laptop that I wouldn’t use all that often (because mainly I’d want it for flying and I don’t do that very often) but I do see where this model fits into the product line. It also seems that Apple is treating this as an appliance since it doesn’t have a standard sized SSD. Most SSDs have the same form factor as a traditional hard drive. This is so you can easily upgrade an old computer but frankly there is no reason SSDs can’t be smaller than their mechanical brethren. Apple decided to say fuck backwards compatibility and toss in a bare SSD stick. This allows the laptop to be smaller but comes at the sacrifice of being easily upgradable. I wouldn’t be too worried about being able to upgrade a netbook that cost $350 but when you’re getting into the $1,000 range I start expecting to keep the computer around for a few years. Still I think it’s a pretty sweet product overall.

Finally the last think Apple announced is the new Mac App Store. The premise is simple, it’s the iTunes App Store for the Mac (well it’s not really an iTunes App Store as the Mac version is a standalone application thankfully). One thing Linux has been able to lord over Windows and OS X are centralized package managers. If you want to install an application in Ubuntu you just have to open the Add/Remove Programs menu, search for the application you want, select it, and click install. Once you click install the application is downloaded and installed onto your system automatically. This also allows the package manager to automatically update your software when new released are brought out.

Apple will finally have this ability in OS X with the Mac App Store. This new App Store will allow you to purchase, download, and install applications onto your computer. The part I liked most about this new App Store is the fact any application purchased on there will be authorized for all of your Macs. Valve’s Steam service does this with games; once you purchase a Steam game it’s tied to your account and you can install it on every system you can log into Steam with. If you go to a LAN party and need to use another computer you can simply log into Steam, download, and install any game you’ve purchased. Of course Apple is doing their traditional 70/30 split but if you don’t want to pay you can continue publishing your software as you have been. Overall I like the idea of a centralized Mac App Store.

Magic Battery Dance

Slashdot has a story about a group of scientists who believe they have found the cause of lithium-ion battery degradation.

As with any such story somebody inevitably posted their magic dance for extending battery life. What do I mean by magic dance? Well it seems everybody and their grandmother have a foolproof system that extends the life of lithium-ion batteries. Some people claim you have to drain them down completely once a month, other say never go below 30% if you can help it, and others will say sacrifice of a goat during a solar eclipse will ensure your battery lasts for years. It shows we really don’t understand the cause of lithium-ion battery degradation (anytime you can ask 50 people a mechanism for doing something and get 50 different answers the true problem isn’t understood).

Well I decided to post my foolproof mechanism for extending the life of lithium-ion batteries. When your battery is showing signs of storage capacity problems buy a new one. Holy shit what a revelation!

This day and age lithium-ion batteries are no longer very expensive to replace. I found a second battery for my Evo 4G for something right around $10.00 (and it was a factory HTC battery to boot). All the time and effort spent extending the life of your battery for a year is wasted if your time is worth any amount of money. Personally I just charge the batteries in my devices when I can and discharge them when I must. I don’t concern myself with cycles, percentage of battery drain, days there will be solar eclipses, or any other such nonsense. Batteries are cheap and by the time you can no longer purchase batteries for a device it’s probably been replaced anyways.

I’m sure somebody is now going to ask what do you do with a device that has a non-removable battery. Simple, don’t buy that device. Once of the features I still look for in new purchases is the ability to easily replace the battery. Yes my unibody MacBook requires the removal of several screws to get at the battery but it’s still easily replaceable once the back cover is off.
