Battery life

So far I've experienced excellent battery. I charged it fully when I got it home, and then unplugged it. Here are my results on an uncalibrated battery with moderate use except for when it sat overnight.

Not to shabby. This was with background data on, auto sync off, with the only the maps app being stopped.

Good one.

My Photon can get me 4 hrs under the same conditions. Let's hope the battery will get better after a few recharge.

From A thread over at androidCentrel posting Epic Touch usage.
Tkemack
Screen On & awake look to be on roughly 70 - 75% use within 14 hr
Photon doesn't come close to such battery performance .
I'm looking forward to some Touch custom roms Battery life will get even better.

Im in debate battery life seems decent for me but no where near what other people are posting. I got 9hrs so far and im at 20 percent with screen on for 4 hours. Dodnt play any games just some web, text and xda. Does this seem right?
The first four hours the powersaver settings were still on. So wifi on, no 3g,4g,no auto sync,brightness at 10 percent.
Last five hours Auto sync is on. Brightness is 25 percent. 3 mail accounts with mail only and I've only had 1 email pushed the whole time. 4g off. Wifi only the whole time no 3g. Screen timeout 30 seconds.

[Q] What the hell is this dip in my battery life?

So, at some point I turned off my phone and I -think- the sudden spike down in battery life is around that time.
Anyone got any explanations?

Mine has done that as well a couple of times. One time I had a charge of around 75%...rebooted my phone, and the battery was down to 15% percent.
Maybe it's just another bug we'll have to deal with until they come out with a fix.

thats strange mine doesnt have that much of a dip

every samsung product I have does this, gt 7, gt 10.1, droid charge, and this one. I don't recall my og droid, evo 4g or 3d doing this.

All phones show a dip when there is a battery pull while the phone is on....

Wasn't a pull, just a shutdown and reboot.

Hi, what app is this?

Stock battery stats lol

**** didn't notice that graph at the top.

well if your phone was rebooted then that bald would have been reset because it displays monitors since last power-on.
there seems to be a bug where the cpu fails to underclock after a certain amount of usage and/or load. rebooting after intensive apps and/or before leaving the phone idle for extended periods of time seems to solve the problem for me. yes i get that too.

Battery life

This phone is only lasting me about 8 hours before my battery will die. What can I do to help out my battery?
Sent from my SPH-D710 using XDA App

download an app call battery calibration, then after a full night of charging, go to that app and calibrate with the charger plug still in, after its done reboot phone and take it off the charger. drain the battery until it shuts off by itself. charge it back up while its off. then continue to use as normal. wait a couple days to see if the battery gets any better. my phone doesnt last too long either, im thinking of replacing the battery to see if thats the problem

Try removing some apps, that worked for me there was some apps that were sucking up my battery.

slap on a extended battery!

Kiss it three times, say two Hail Mary's and toss it over your left shoulder.
No seriously, battery life is very dependent on many things, and your statement doesn't come close to providing enough information for anyone to give you any real help. At minimum you need to provide the following during your 8 hours ...
- Total Display on time
- Brightness setting
- What you have auto syncing and how often
- Average signal strength
- Usage pattern (web browsing, calls, streaming video, etc.)
- Widgets on your home screens
- Screenshots of your battery usage and graph

My phone will also last around 8 hours if im constantly using it.

Thanks everyone for the responses. I will try out all the advice.

With moderate use, I get about 20 hours. With heavy use I get about 10-12. It's still enough to get me through the day
Love this phone!

(TIP)Possible battery drain solution for LTE devices.

Like many here I've been having battery drain issues since the day I purchased the Galaxy Nexus. I also purchased the extended battery since day one. I've been reading through every single forum on how to reduce the battery drain and none seems to have worked for me. I've tried switching to wifi, 3g only, no email push, no google+, etc and my phone at 100% battery would lose almost 30% within 2 hours idling. Then I was looking at the settings and I came across the Developer Options/Background process limit and limited my background process from Standard to At most limit to 1 process and my battery has improved tremendously. Prior to making the change the Android OS was using 80+ % on idle (Wifi or 3g didn't make a difference), now it's uses around 20 or less. On idle I'm seeing around 4% or less an hour vs 15% battery drain.
Please remember this may or may not solve YOUR battery drain, but it has definitely helped mine and I just wanted to share with the community on what else you can try.

I've had pretty good results with my battery. I think some of ya'll are either just playing around with it too much or have some energy-sucking apps out there.

Or that you don't have a connection to the data network.
Just say'n. (I do the same thing at night)

I had Wi-fi enabled for 12 hours, and the battery only dropped to around 85%. I have been on 4G for 5 hours now, and the battery is now down to 13%. I'm going to use a Wi-fi/3G combination tomorrow. Oh and I also have my phone rooted/underclocked to 900Mhz.

I've been using it for 3 days and have had no issues. Anyways its as easy as checking the standard limit if you ever wanted to revert back.

Is anyone else's battery on crack?

Usually I can go a full 16 hour work day without needing an extra charge, then last week it started not holding the charge so well. In fact Tuesday it had 30% and I left the house for half an hour, and when I came back the phone had shut off and was at 0. I hadn't even touched it. I am on a mix of Wi-Fi and LTE. Anyway, that was odd. Now look at the battery usage...

Do you have a screenshot of the stats when the battery went all out of whack?

My android system has been going crazy the last week or so, usually would be at 5% our do but lately has been 40+ easy... been to lazy to wipe and re flash as I'm sure that will fix the issue, but lately I've been near power all the time so it hasn't really bothered me.
Sent from my SAMSUNG-SGH-I747 using xda premium

I flashed with Highonandroid and got 30+ hours. Probably could have gotten double if I didn't kill half of it installing all my apps back on.
What rom are you using?
On the stock image I was only getting 9 hours.

it looks like weatherbug and google maps take a lot of battery

i never truly understood why people boast of their battery life when they have the screen on for 10 minutes in 2 days

if you are not using a phone, turn it off and the battery will hold charge for many, many days.
