I've seen lots of battery life forums, and most of them show great battery life (over 12 hours) with lots of screen time. I'm not even in an LTE area, but I get very good signal. My screen brightness is at about 30% and I have two e-mail accounts (Exchange push and Gmail sync).
First, here's the constants: I keep wifi/BT/GPS on 100% of the time. This was true when battery life was good, and now that battery life is bad. Disabling these will improve battery life, but will not fix my problem.
When the phone is sleeping overnight, I used to get 8-12% battery usage over about 8 hours.
Ever since the Jelly bean update I have been getting terrible battery life. I had all of my settings turned off and my screen down to the lowest setting. After a while I just got sick of not being able to use my phone so I bought an extended battery off of ebay for 12 bucks. Take a look at these screen shots.
I love be this phone. Well, I really want to live it. However, I'm quite disheartened to hear others talk about the superb battery life in the LGOG, when I find the battery life in mine as simply atrocious. Under moderate to the-low-side-of-heavy use, I *might* get four (FOUR) hours of use. In tried eco mode, but that didn't help.
I know we have a lot of battery life threads and I absolutely love this phone but mine is not getting good battery life. I'm an advanced android user, I know it well and I do know that some devices just have bugs which kill battery life.
I am a happy Android user and have an HTC Desire Z. A family member has a basic Nokia texting phone (Nokia C3) and I would like to get her an Android phone so that she can have her Google e-mail and calendar on-the-go. I will buy the phone second-hand / unlocked.
