Help Can anyone explain my GNex battery issues?

[apologetickid]

I use the extended battery, which used to get me through the day easily. But lately, this is what my battery looks like after only 6:45 of use: Photo Album - Imgur

Can anyone explain why my battery is dying so rapidly? The screen wasn't on all that much, and when it was, I have my background and many of my apps set to use a black background so as to use as little pixel power as possible. Still, the screen claims to be the main culprit.

Is it possible that I have a defective battery, (or worse) a defective device altogether? Is anyone else having battery issues that are THIS bad?

Any help would be appreciated. Thanks!

You phone was awake. A lot.

I can take my phone to work with me (I work 10-12 hour shifts) and I might pick it up 5-10 times a day to check for missed calls or texts. I might send check Google Currents (which I wish was about 1000 times better than it is now) or some feeds during the day, but for the most part it stays in my pocket or on my desk. I can easily make it through my entire shift and have battery left.

I worked a shorter shift today, thankfully (only 8 hours) and just got home and this is what my battery looked like: https://lh6.googleusercontent.com/-...KjhW8/s720/Screenshot_2012-07-27-00-43-52.png

Sure, I didn't do a whole lot with it. I made 3 phone calls, that probably didn't total more than 15 minutes. I sent some texts, sent some messages on Steam, checked out Google Currents (pretty neat article about someone making an AR-15 with a 3D printer) and that's really it. Sure, I didn't do a whole lot with it but I also have it syncing by itself, with the GPS on and the screen set to auto-brightness. I'd say 15% in 9 hours isn't too bad.

I think it is also important for me to include that I get horrible reception at work and have to connect to the WiFi that is two businesses over to save some of my battery life. The WiFi, like my reception goes in and out though. Reinforced coolers/freezers and brick walls don't seem to do well for my signal. =X

Wow. I am stunned by your battery life! I can't figure out how to make mine work like that. You said my phone was awake a lot. Do you have any tips on how to prevent it from doing that?

I really appreciate your help!

one thing that may help is check WHAT is being updated regularly/constantly... example.... facebook feed, twitter feed, stuff like that. set it to Manual update instead of CONSTANT...

download better battery stats from XDA for free (or paid in the play store)
use your phone normally for a day, then open up BBS and check your partial wakelocks.

it should give you some apps that are keeping it awake

those long blue lines under "awake" should not be there (unless you were streaming pandora or something) in a perfect world, there shouldn't be any awake time when the screen is off.

bt BBS will help you nail down what is keeping it awake. it is usually an app that is misbehaving or one that you recently downloaded/updated that is not compatable with your phone version. remove the app and you will be golden.

Looks like you were streaming music. I see mediaserver and grooveshark were running a lot. If you are streaming anything over 3g/4g that will use a lot of power. 4g more so. WiFi is much better for battery life if you have access to it. Always use Wifi whenever possible.

What your battery graph looks like ideally is that the phone is awake only when the screen is on. The less is running in the background the better your battery life. Obviously, things like checking email and getting texts and such are necessary, but you want to eliminate unnecessary background processes. If you choose to stream, you have to recognize the tradeoff. No way around that besides plugging in. I have a bunch of writeups linked in my signature, but certain apps will run a lot in the background. I disable any syncs that I don't need. I sync my contacts, calendar, browser, gmail and that's it. Facebook sync and google+ are known hogs. If you don't need constant Facebook and twitter updates (which really, who does?) turn off those syncs and just let the apps refresh when you open them.

Here's what my typical battery graph looks like. Notice how the "awake" and "screen on" lines are mostly in sync.

This is helpful. Thanks for your time and input, I'll look into turning off some of my syncing. But yes, I was listening to music for part of the day. I'm going to experiment today by using only wifi or 3G. Now that I think about it, a lot of my problems have only come about since my area started receiving 4G. I wish there was a quick 4G toggle switch that worked with my 4.1 ROM.

My biggest tip for battery life is NO FACEBOOK APP. Seriously, that thing destroys battery in more ways than one.

Try to avoid streaming HD videos (or anything that keeps the screen on) too much. Using the 4G radio, as awesome as it is, is a death knell for the battery as well. I know I'm just echoing what others have said, but I make my phone make it... a lot. I have a new screenshot for you today...

Good luck.

Edit: I would like to add, that after posting this I realized my sig says I'm running a 4.1.1 ROM, which I am no longer running. I've got back to AOKP, where I experience the BEST battery life.
