Explaining Battery Life On The BlackBerry Z10
One of the largest complaints that can be made about the BlackBerry Z10 is the battery life. Whether it be from people who have owned the phone for a month or people who have owned it for two days, the consensus is that battery life on this device is mediocre at best. While some of those complaints hold merit, there is an explanation for the battery life not being as good as it could be at this moment. With patience and understanding, the battery life issue will become tolerable or nonexistant.
With any new OS, there's bound to be variables thrown in by different applications or processes that complicate battery life. I've seen numerous people point out that they believe certain applications (eBay, BB Travel, etc.) are to blame for bad battery life. Bad coding could potentially be an issue, but these are things that don't generally last very long as either BlackBerry or the developer figure it out. Do not be discouraged to use certain applications right now for fear of losing battery life; the whole purpose is to enjoy the phone. These aren't problems that will persist.
Managing sync has probably been the biggest difference coming over from Android. I'm using two email clients now on the Z10 as opposed to one on my Nexus 4. Having it pull every 24 hours for every process (calendar, contacts, mail) has made a pretty big difference in my battery life. I get my email on time, but the sync for the calendar and contacts shouldn't need to be updated on an hourly basis. If you're using multiple email accounts, I'd suggest doing the same and prioritizing if you haven't already.
If you're on AT&T like I am, you've probably noticed there's not a way to shut down LTE to conserve battery life. While I'd like to be able to choose, I understand why AT&T is doing it. Using LTE means you're using more data and also freeing up their HSPA+ network for faster speeds all around. Of course, if you have WiFi, that can solve this issue. With that said, you're also enjoying some ridiculous download/upload speeds so it kind of evens out. if the Z10 wasn't fast enough already, loading web pages and downloading anything is infinitely faster on LTE and it makes the experience pretty gratifying.
Screen brightness is probably the biggest offender as far as battery life goes. The initial shock of lowering your brightness to 30% or under is kind of annoying, but eventually you don't really realize it and it becomes natural. It also makes a big difference. If you're someone who just can't live without the screen brightness being near maximum, your best bet is to keep the screen timeout around 15 seconds. There's really not a lot you can do to counteract having the brightness that high, but that's your best bet.
Battery life on the Z10 overall, which runs a brand new OS, is really not that bad. Your first few days are going to be the most brutal (you'll inevitably be playing with it more often/it hasn't run through a few charge cycles to maximize it's life) and a snap judgement on battery life at that point is pointless. It IS removable, something only Samsung has been keen on doing lately outside of BlackBerry, and that makes a huge difference. Using two batteries with a spare charger constantly charging the depleted battery will easily get you through the day. BlackBerry is aware that there's things they can do to increase the battery life, as well. QNX is actually really efficient and as time goes on, I would bet that battery life will no longer be a concern on this phone. The majority of the upcoming updates will be focused around it for sure.
For those that haven't used a Z10 yet; do not be discouraged at the reports of battery life. It is no worse than most of the top tier smartphones (all of which I've used extensively) and holds a huge advantage of being removable. The processor/clock speed, the screen size/brightness, and OS are all things that an 1800 mah battery can maintain very well. BlackBerry just has to clean some things up to get it to realize it's potential. Knowing this company like I do, they undoubtedly will not disappoint.
