My battery life is stellar

Not sure what you people are doing wrong but I get great battery life running codename android 1.3 and Franco's nightly. Keep 3g on most of the time and use 4g and wifi at home. This is from yesterday, wish I could've let it fully drain but I had to go to work and swapped the battery. This to me represents real world use, played around on the internets, texted, and made a few calls while at work and used pulse heavily after I got home. Kept 3g on while I slept (why do people put it in airplane mode or turn data off?)

the only relevant thing would be screen on time

Your screen on time is very low.

Can someone explain to me why we have 50,000 battery threads? I think we get it! Your battery life is great. My battery life is great. Jane's battery life sucks. Jim can't even figure out how to turn on his Galaxy Nexus.
Stop with these threads!!! And you know what, to add insult to injury... My battery life on the stock ROM destroys what you just posted.

Thanks for the laugh man. I needed it. These threads have gotten so out of hand, it's ridiculous. A Mod should just combine all these redundant battery threads into one giant thread so they can all piss in the wind and see whose goes further.

My phone is very strange about battery life, in fact sometimes it lasts 26/27 hours and sometimes, with the same usage more or less, it lasts 15/16 hours

That's pretty good, I can barely get mine to last overnight with literally NO USE, BUT SERIOUSLY ANOTHER THREAD?

Ripping tale old chap.

New galaxy nexus user

I got new GN and it is very good but one thing is ruin it and it is battery life example an hour ago I took phone from charger and it was 95 and kept it in my pocket for half an hour and just loses 3 % and then played scramble with friend 4 games and now battery is 77%.
Even my old galaxy s would use less than that
Sent from my Galaxy Nexus

i dont know if this will work, but test this and then let me know if it makes a difference (you'll need to spend a whole day testing this) not just an hour
go to settings -> developer options -> in the apps section at the bottom put a checkmark on "don't keep activities"
then do a comparison
one day with it with normal phone use, and one day without it with normal phone use

I will try it tomorrow
Can you take a look at this and compare it with yours cuz screen is consuming so much
Screen is on manual and lowest brightness and wireless is off and GPS off

Pictures aren't showing up for me but the battery life is horrid on this thing. The screen is gigantic and beautiful its the trade off we all took
Edit they loaded. Looks like my usage more or less.
Sent from my Galaxy Nexus using XDA

why don't you go a few days and post your usage with normal full-day stats? You can't look at a couple of hours of usage and say it sucks. Also, why are you on EDGE? You're gonna burn more screen sitting waiting for things to load on EDGE than just using HSPA+.
But battery life is a well known "issue". The screen eats battery. Turn off live wallpapers and turn down brightness. Do all of your general battery saving things (turn off WiFi, BT, etc. when not in use) and you'll see battery life improve.
The most you can expect with "normal" (which is suggestive) usage is probably 18 hours total with 3.5hrs screen on. More than likely something like 13-15 hours.

What about custom roms is there any custom rom that has better battery

Roms aren't going to affect battery life as much as kernel will. As far as kernels I love Franco kernel. I used to use faux with a good experience.

Well the 2100mAh battery is about 13% larger... so 13% more life.

The battery? Yeah... They're sold from plenty of Korean eBay sellers. Official branded Samsung batteries.
And since you're on GSM, its 2000mAh (instead of stock 1750mAh). The Verizon one is 2100mAh (instead of stock 1850mAh). They are NOT compatible.

cell standby a hardware issue???

long time android user, and my GF just upgraded to her first smartphone to the galaxy nexus, same phone i have. and the battery sucked, she had 50% left and went to work and within 2 hours it was dead, so i unlocked/rooted. and installed aokp 3 milestone along with franco krenel to the latest milestone. same rom and kernel i have, and i get atleast 14+ hours on regular use nothing turned off.
her battery status looks like it usally the cell standby to blame, could this be a hardware issue? i completly wiped data/dalvik/battery and did new install, going to try again flashing back to complete stock. but could this be a hardware issue?

Turn off 4g.

have you checked if you both have the same radio? you can try that
also maybe check hows reception on her workplace

So... she had bad signal. Phone sat there trying to get 4G / hang on to a bad signal. Will drain the battery 100% to 0% in a few hours if you let it do that.

no i haven't tried turning 4g off yet, shouldn't have to i wouldn't think. she lives in seattle and i live 30miles further north of from her, and i don't have a problem with 4g conection. but i'll try that just to see if it gives a different result.

Well I can tell you right now, AOKP gets absolutely HORRID battery life. Try BAMF.
Sent from my Galaxy Nexus using XDA

Download juice defender and set it to balanced. You will see a HUGE difference with standby drain.

If you have a third of the time without signal, I would expect energy to drain a lot, as the radio will keep trying to find a signal and consume way more energy than if it is connected and in stand by.

Nothing wrong with AOKP battery

yea im useing AOKP and get great battery on my phone, but not hers, thats why i was wondering if it COULD be a hardware issue, or if this is always a software issue.

Update to 4.04 u will get battery like this.

Ditto that. It's easy to blame a particular ROM for one's battery woes, but the truth of the matter is it's invariably something else causing the drain.

Her signal is destroying the battery, turn off 4g and if she only does the Facebook thing and messaging do the following

Constantly turning on/off mobile data when the screen is off will more than likely drain the battery more than leaving it on. Not to mention that you'll get no background sync or notifications.

No I think you have to turn it off if its right on that fringe area. Plus lte networks and radios are very immature ans have a lot of years to get fully optimized and tweaked to match current cell coverage performance. You're using a brand new network technology that has a long way to go. Beta testing.

Battery life 1st impressions

Does it take awhile for this battery to settle in? It's just been 2.5 hours since my first charge and I'm already down to 90%. All I did was send a few texts and receive a couple of short calls. Can't remember if I experienced this on other phones but after hearing about how great the S3's battery life is, I'm a little disappointed.

I think it's great. It's a lot better than my Epic 4g Touch, that's for sure.
And 10% per 2.5 hours is pretty good IMO.. That's 2.5 * 10 = 25 hours of battery. That's pretty sick lol.
Just remember to turn off wifi/bluetooth when not in use, and turn off LTE if it's not active in your area (so the phone doesn't keep searching for the 4G signal).

Yeah, wait for it to settle. This phone definitely has the best battery out of everything I've owned...and I've had a few phones, believe me lol

How is your signal? Have you been in an area with wifi? Radio signal has been the biggest issue for me...

I've been on wifi the whole time.

I sometimes get more than 2 days on a charge. I try not to use phone while charging, causes inefficient charging(supposedly).
this message brought to you by my GalaxyS3 running Phantom's Blazer v1.6

I must be doing something very wrong. I really got horrible battery life in my phone and I only got 4 apps installed: xda, rage of bahamut, Facebook, and power amp. The ones that can be on sync I turn it off. I'm currently running on CM10 but was on stock for about 3 weeks and blazer for about 2 weeks. All with similar battery life. 2 hrs of screen on time with 13 hrs on battery. On my epic touch I could do 5 hrs of screen on with 24hr battery and evo lte 7 hrs of screen on and 18+ on battery. I've already switched batteries so I know its not a defective one. I got no email syncing and brightness is always set on lowest unless I'm outside its at 50%. I will try to post a picture of better battery stats, CPU spy, and see if anyone can help me figure out what I can do to improve it. Really disliking battery life right now and hope it will get better
Sent from my SPH-L710 using xda premium

I personally just went 26 hours with 3 hours screen on time in CM10. That's way better than my Evo 4G could do, so I'm extremely happy with my battery life by comparison. This phone has been awesome for me.
Edit: That time includes leaving Wifi and mobile data enabled at all times, with data mode set to CDMA/LTE. I also left everything syncing like normal.

Coming from a EVO LTE so far my battery life been unimpressive. Loving the phone, but not digging the battery.

This phone is right on par with my iPhone 4's battery (which is a beast). If you think this battery is underwhelming, you obviously haven't had the original Evo 4G lol

If display time could last > 4 hours this phone would be perfect... but alas

This still makes me sad :/ Never gonna get over 3 hours of display time.

Mine must be perfect then.

Hell, I'm lucky to get 2 hours in a charge

Yeah, the battery life for our phones is not the greatest, I've found a spare battery to be a must for longer days. I do get better battery life than what you're seeing though, an average of about 4 hours screen on per charge, with about 15-17 hours of standby using the standard 1750 mAh battery.

Yeah... it's crazy. It's the one hindrance of smartphones... 4G + 4hour + display time would be ideal. FCC should make a mandate about battery life... "Must exceed 5 hours with the display on full brightness with a low signal 4G"

I'm not sure you understand what the FCC does... Vote with your wallet if you want a change, go buy a phone like the RAZR Maxx with a huge battery, complaining here won't do anything.

op, your signal strenght is very low. switch to 3g. gsm radios will always consume less power. we on maguro can get over 3h display, easy!

Yup, the GSM guys get much better battery life.
My VZN Gnex has less than 2 hours screen time with mixed LTE and wifi on a good signal. That said, I'm still going to complain no matter how many people say to switch to 3G. I believe consumers buy products because they should be good, not so they can make sacrifices after purchasing a product. As of yet, the VZN crowd doesn't have much of a choice for Nexus devices, so Gnex it is.
Make do with what ya got and don't let some battery life stop you from enjoying your phone. Just charge your phone if you get the opportunity and don't let it bother you.

Other phones are worse, some r better. No one says u can switch to a phone with better stats. I'm not complaining cuz I come from a droid charge where ubhad to tweak the crap out of it to get 2hrs of screen on time.
