[Q] bad battery??

I have been using the lte g.nexus for about two weeks now and i cannot stand the battery life let me explain
Im on screen timeout 15 sec auto brightness.
Operating on 3g mode only and my average batt time is abouy 4 hours of moderate to heavy use(no bluetooth r gps included) ive heard stories of batt conditioning when i got my g.nexus i charged it to green and immediately begin using it. I even let it drain to zero the first two charge cycles. I dont have any syncing apps doing auto sync except my google account and no one app seems to be sucking juice the screen is always using between 40%-60% in the usage stats is this normal i.never had this problem with my bionic.

that F'ing ridiculous that you are only getting a few hours on your g-nex especially since you have turned a lot of things off or to a minimum. i would either go to a verizon store to try to get a replacement or purchase an extended battery.

Not trying to hijack this thread but I'm starting to think my battery is bad too. I've been giving it time because this is only my 4th day with it, but its just atrocious.
Yesterday: charged to 100% and took off charger immediately around 4 pm. After a moderate amount of texting, 10 minute phone call, and my 4 Gmail accounts syncing in the background on 3g the whole time, the battery died around 11pm. The screen on time was maybe 1.5 hours.
I'm running Android Revolution rom with the included stock kernel. Everyone reports about how awesome the battery life is with that rom, but if 7 hours is good battery life then I don't know what to expect.

Im starting to wonder if the phone or either the battery is at fault because i see a lot of usera spread out across the net complaining of similar problems. Is there is a certain way to traim the batteru the first day or so because i love this phone but i refuse to buy an ext. Batt jus to make it thru a work shift.only on 3g ..anyone else having this problem or know of a fix?

I've heard some glitch about the camera sensor staying on in the background in a different thread. Search for it in xda

My battery was only worknig for a few hours with the extended battery when i looked at the battery usage it said 70% mediaserver. looked up online and it said if you have a picture or vid that is corrupted it can cause mediaserver to keep trying which i had a photo gallery widget on home screen. when i deleted img and deleted widget im now getting like 10x more battery life.

I am getting good battery life.
During my sleep or when my phone is idle or when I know I am not using it for a long period of time, I switch my phone to 2G.
Below is a screenshot of my battery usage during a long period of idle (overnight when I am sleeping)

I only switch it to 3G when I am actively using the Internet for surfing websites, Facebooking, Youtube, uploading photos or video.
Below is a screenshot of my usage from light to moderate to heavy.

I went into the bathroom with full charge and after I did my daily deed(s) I went down to 43% with brightness turned all the way down and only running xda app. wtf gives?

New original battery + Full first time calibration = 4h15 of screen time

I just bought a new battery this weekend ( original 1750mah ) and i did a first time calibration ( charging for 10h without unplugging and drain it all until my phone closes by itself). Now i have a freaking awesome battery life with mid-heavy usage. 4h15 of screen time with 50% brightness, wifi on all the time, gps, auto-sync, franco kernel #11, XDA for few hours(white background), youtube, about 250 txt messages, 30 min of talk time. I just beat a new record submit your best screen on time.
**next step : 5h of screen time ( 30% brightness, no facebook app)

If you search here, someone made an experiment. He set to airplane mode and set the screen to display all pure black with lowest brightness. That resulted with about 10 hours 40 minutes.
So, that's max screen on time with standard battery.
Here my battery life with extended 2000mAh GSM battery
Granted, I don't sync and I set to brightness at 10%. But that's enough for me. Mostly I use my phone for web browsing, fb, g+, xda, games, etc. The stats below include Sygic GPS navigation for about 20 minutes.
At 61 hours stand by with 4 hours screen on time, I am very happy

I've gotten 5.25 hours as my record. Was strictly a wifi data run. I've also got 4.75 twice, HSPA data, but your 4.25 is probably more impressive if your background is that and the other stuff mixed in. All 1750 mah. Just got my 2000 mah yesterday.

I am getting about 5 hours of on screen time with my gsm Galaxy Nexus with the 2000mah extended battery from simshop,wifi on,100% brightness always & none of my settings are focused on saving battery life.Here is a screenshot of the wallpaper I usually use,sometimes I throw a lwp on.I also for testing purposes put Netflix on at 100% battery and streamed until the battery got to 5% and ended up getting 4 hours 23 minutes with the same settings as I wrote above.I am running 4.0.1 stock deodexed rom.Stock kernel.
Maybe this will finally be the thread where everyone actually shares the relevant information like Rom & Kernel,GSM/LTE,Extended or Stock battery, Screen Brightness,Sync on/off,Wifi/Data,Static or LWP.On screen time as opposed to just how long the phone has been in idle & even possibly the technique used to calibrate the battery.

FYI all the posters above me are GSM GNexus owners.
max you can get on a LTE device running 4G all day is about 2hrs 30 minutes max on-screen time.

Using redemption rom with stock kernel. Yeah I have wifi on the whole time I'm home. Which is usually from 4- til I plug in. I am on the extended battery. But I don't notice much of a boost from the normal battery with it. I also have gtalk signed in all day and use that almost constantly. Although today I haven't. My phone also always stays cool. It never gets warm.
Also I have everything on normal sync. Gmail,fb,twitter. And auto brightness.

If you're using 4G+wifi, aren't you really just using wifi? With wifi on, I can make it through the weekend easily with light to moderate use. 4G, not so much.

6 hours screen on?

Sure sure it's with light use, but just the fact that it can hit 6+ hours screen time after more than a day and a half... sits pretty well with me.
No games, 30% screen brightness, 74 mins of calls, quite a bit of texting & whatsapp, 30 odd mins browsing, wifi 100%, sync on, only 1 widget.

Not bad at all! Especially considering 74min of phone calls.

NICE!!! Can't wait till my extended battery comes in.

Nice. I've had my extended battery for 2 days now and I am seriously impresses ed with it. It on my drive home I'm at 65% instead of 30%. I really think the extended battery should of come stock.

I got a similar 6 hour in airplane mode. I was watching a movie while roaming on vacation.
Verizon stock rom. stock battery.

Even stock SGN makes wonders with battery on Wi-Fi But still your stats are truly amazing

OP did charge the phone for a bit....like 3 times don't know for how long....but nonetheless amazing stats...

No, he didn't? Look closer on first screenshot. There is no sign of charging on those lines below the graph. Those places where graph line goes up are pretty normal and that doesn't mean device war charging.

Nah I didn't charge it at all, as the other guys pointed out. I remember my battery dropping to 4%, I then put down my phone and when I came back later on, it was reading 5%. I thought I was going crazy, but looking at the graph now I see it really did happen. It raised from 4% to 5% and stayed there for a bit before dropping to 4% again.
Anyway, I hope this wasn't a one off... it's not doing as well today with the same usage. We'll see...

Actually, the phone calls don't do much damage... You should be able to talk 11hours on this phone apparently...

I am very jealous. I am lucky to get 3-3.5 of web surfing.

With standard battery, you can get almost 11 hours screen on time (by doing nothing):
http://forum.xda-developers.com/showthread.php?t=1366878&highlight=max+battery
So, that's the limit
My experience with extended battery, 2000 mAH, GSM, I could get 4 and a half screen on time with 61 hours stand by time. For sure, it can go down to 6 hours or more screen on time if I down the standby time. All with stock ROM, stok kernel, un-locked
It is not difficult to achieve that knowing the limit, all depends on how you set it up and how do you use your phone.

Battery Life for you Heavy Users

I know another battery life thread, but I want to know what battery life people get that are heavy users. What i mean by heavy is people that play games for an hour, watch videos, surf the web, music, download, calls, text. Things that would drain the battery quick and because the screen is on.
On a regular day I mostly text get about 1.5 hours of music and 2 hours of video/game. I don't play games all that much just watch videos during my breaks, surf the web allot and download small files. I have always kept WiFi and GPS enabled on all my android devices.
I had the SGS for 2 days and noticed it only lasts about 12 hours, my previous phone (hTC Raider) with the same usage would last about 14 - 16 hours.
What do you guys get? somewhat disappointed with the battery.

4 to 6 hrs screen time.

That's way better battery life than me.

@ I_FLY_Z3R0
That's impressive I may have to check out that ROM. It funny how you guys get around 16 hours and i only get 12 I wonder what it is?
I'm starting to remove bloat and hopefully that will improve my battery, will post back at the end of the day.

Out of curiousity is everyone on a custom rom, is anyone on a stock rom and getting these numbers (I apologize if i missed this but i dont think i saw it). Im rooted but still stock on sprint and I am getting about 8 hours. I have about 4 gmail accounts sync, 4 groupme accounts sync, gps and wifi enabled. I typically lower my brightness unless im outside or in a hard to read area....any ideas? I was really ok with not trying custom roms but if i can double my battery life by doing so i might reconsider....I was on the OG Evo before and flashed like crazy to get better battery life but no matter what others said they got, I only got 5-6 hours on similar setup that i just mentioned.

I'm testing my phone to make sure it lasts me my heavy day. Coming from GNEX i have to make sure that it's worth $600 i just paid.
now i'm getting 5 hours of talk time + 3 hours screen time (auto) + 20-50 text/emails. this is with power saver setting without CPU max limit.
and at the end of day (8PM) i have around 18 hours on batt, and 20% left.
Hope that helps.

This was extreme usage. Audio constantly playing and tethering on most of the time.

Judging from the fact that he's on Blazer rom (I used to have a GSII), I'm assuming he's on sprint. Assuming he's on Sprint, I'm assuming he does not have LTE in his area yet. This could account for the huge difference in how long the phone lasts overall.
Being on AT&Ts LTE, I can get around 4 hours of on screen time and 15 hrs overall of medium use.

Here are mine. Mostly idle, lots of reading(Game of Thrones books, awweesome!), emails (all work related) and light gaming. 5% left after 20 hours, almost 4 1/2 hours screen time. I am running stock rom, rooted and I debloated a bit(few pre-installed apps, gmail, email, etc as I use other apps for those needs).
Uptime 5% left on battery.

Very poor battery despite reviews?

Had my Note 2 since Saturday and the battery seems really poor to think everyone reviewing them said they were fantastic.

Day 2 from full charge to 6% I had 17 hrs 10 mins
Don't seem to have any rogue apps from battery monitors I've tried which makes sense as I've only downloaded about 10 apps.
Always have WiFi and GPS on which I always do on any phone, and have auto brightness off and set manually to just under half way.
I have dropbox set up to automatically upload camera pictures but under battery monitor this only uses 0.5% of battery use.
I also seem to have a faulty S Pen which sometimes seems too sensitive as it'll draw or open menus/apps with the pen about 1cm from the screen, and other times the pen doesn't recognise the air/hover mode and I have to press firmly to draw.
Any ideas?
Between this and the over sensitive S Pen, I'm beginning to think I just have a faulty phone!?
If it was as easy as taking it to a store I would, but I received it free with a 2 year contract from an online company in the UK called Affordable Mobiles who seem to have pretty good reviews. They've said if I want an exchange or them to have a look at it I'd have to send it back and wait 2-3 days which I can't do really as I don't have a spare phone - but at the same time I don't want to start rooting the phone and messing about with launchers if it is a fault.
Thanks

Turn off gps. Thats sucking away your battery mate. Turn it on only when u need it.

IMO, to get more than 1 day with WiFi & GPS constantly on is good. On my Note 2, I am usually left with around 30% of battery left at the end of the day but I never have GPS turned on unless I need it, only my WiFi is on.

So why are you posting this exact same message in multiple threads without explanation?

Try resetting the phone and check it for another day without installing any third party apps if it gives the same result that it must be a faulty phone. Hope it helps.

Thanks guys, I'll try resetting it as suggested and see how it goes for a day or two.

You should judge your battery stats from your screen on time. Regular usage with sync and wifi and data enabled should get you between 5 and 8 hours, but it's possible to reach 10 and beyond with low brightness and no connectivity. If it's below 4, you can start thinking that something is wrong if you didn't do any crazy gps navigation or something, and start from there.

Sent from my GT-N7105 using xda premium

Well, mine can lasts up to 2 days with Wifi turned on when I'm awake. Also I have roughly 5 hours screen on time on average. Quite achievable with heavy debloating of the ROM and using custom kernel and probably with some undervolting done too.
P/S it's my first Android. Still learning. Please correct if I'm wrong :fingers-crossed::fingers-crossed::fingers-crossed:

So far on my third day I have 10% left with 1d 5h on battery and 5h 13m screen on time.
Regarding issue I mentioned about the S Pen, Samsung are sending me a new one to try and rule out the phone
