General Battery life

http://androidforums.com – Hi all; I'm a recently converted lifelong iPhone user so please be gentle. I couldn't be happier with my new GS3 but i'm concerned about the battery life. It's nothing like my old iP4. 5h 05m 15s battery usage 31% Battery left usage stats: 29% screen 28% android system 15% cell standby rest = various games & apps... no single one more than 9%. This seems REALLY REALLY poor. Can someone compare this with anything for me ? I have no point of reference and I need to know if i have hardware issues or if this is what it is. Thanks! (General)

Hi guys,

I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess. My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge).

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.

Hi,

i recently changed my battery to the one x+ one and hoped that I got a better battery life with this. It is better indeed but never the less the battery doesn't last a whole day.

Hi guys,

I charged my phone full last night and unplugged it around 8.30am this morning. As you can see from the attached pics, by 12.30pm my battery had reduced to 22%.

The screen time was around 1 hour 20 minutes at this point with voice calls about 10 minutes.

...im running a stock 2.2.2 optimus 3d. I factory reset it last month after my wifi had issues. I have 17 apps from Google play downloaded. As well as a 16 gig SD card. My phone will randomly shut off 3-4 times a day. Usually under heavy usage. I game text surf etc. During standby I get great battery life. The min I use regular to heavy the battery just drains in a blink of an eye.

Poor battery life? Replace it! 15 weeks 2 days ago

Im guilty. Ive had posts on here about poor battery life. My phone isnt even a year old and the battery life just had become horrible. To the point it was 2 recharges per day.

I blamed the OS and updates because it just didnt seem like the battery should be gone. I was getting 9-10 hours on average.

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.

Greetings all ,

I noticed that my battery on Xperia tablet s draining very fast . For example : i am on battery for 4h 24 minutes and i have 76 % left with 1hour 26 minutes screen time .( Which i made some internet Surf and watch some video) Android OS has 26% of usage with Keep wake 2h 16 minutes.

Is that ok ? or something going wrong with my battery?

So, the other day Barnes and Noble announced that their updated NOOK ebook reader had battery life of two month and hailed it the ‘longest battery life of any eReader.’ But what kind of usage is it based on? Is it realistic? How does it compare to Amazon’s Kindle?
