My battery life

Hi, I am noticing that my battery life is very short. I have to charge my phone atleast twice a day. Last night I watched a program on my phone which was forty minutes long. After that my battery was already 60 percent about. However.now, in the morning, I woke up and checked one thing on the internet by 3g and now my battery is already 40 percent. Why is this .... I know that battery life on here is not good but mine seems worse.
Is anyone getting the same?
Thanks in advance.

Tell us your settings:
- Do you allow background data?
- Do you always synchronize?
- Do you enable data connection?
- Do you connected to the Wi-Fi all the time?

I swear my battery life is far far better since i put that Generic rom on, maybe the minor updates htc have released help battery life ?

Maybe the update will fix the battery life issue? We'll see when it rolls out on t-mobile handsets.
Other people have reported excellent battery life (mine only arrived today) and it seems to improve over time. How long have you had it?

I had mine 1 week today was originally on the T-Mobile rom and have had terrible battery life up to even yesterday, updated to the Generic Rom yesterday and it honestly seems to last longer now.

I was waiting for someone to report this before I did .. I too was originally on the T-mobile ROM and updated to the Generic ROM. I didn't notice any increase in battery life. In fact I didn't notice any changes apart from the minor T-mobile branding having gone.
Yesterday I did the OTA update and again didn't notice any changes. I did this morning though, in 10 hours the battery only dropped 4%. Of course the phone hadn't been used in that time and I have wi-fi and bluetooth switched off but I am sure this is a lot better than I was getting.
Maybe the OTA update has improved battery life. Let's hope so.

Hello again,
Is the generic Rom the Rom without the T-Mobile stuff?
How would you get that? And would that remove your warrenty / insurance?
How have some T-mobile people get the OTA update whereas some have not?
Have you realy found a difference with it?
THank you

Yes to without T-Mobile stuff.
You can download it in the Android Dev Desire section on here. There are extra steps to take.
It WILL void your warranty.
Anyone that got their phone direct from T-Mob will NOT have it unless they did it manually. And by that i mean manually flash generic rom then update.
I noticed my battery is better but it's only one day. And i never really had a problem with it. I charge once a day anyways.

Thank you for the help.
However I am unsure if I should get the generic ROM.
What are the other advantages?
Because there is not a lot of T-Mobile stuff on there.
If I got mobile insurance with T-Mobile and flashed the ROM would I be able to claim if my phone got damaged or lost?

Advantages. The phone is as it would come straight from the manufacturer. You will always receive updates for the device before Vodafone, O2,T-Mob etc would have them ready.
If the phone was lost then yes. If damaged...probably not but if it develops a fault you can always drop it in a drink and claim on he insurance...bit dodgy like!

My battery life story
So, I downloaded the brut Google nav mod the other day and haven't had a chance to use it until today. Took a journey which took about one hour, and made sure that my battery was fully charged before I went. I still hooked up the phone to the car charger though, to save power. One thing I noticed about charging the desire, however, is that if it identifies the battery as being already full when you connect a charger, the indicator light stays green, so doesn't top up even when you have been using it for a while. I noticed this about 20 minutes into my journey by which time the battery must have gone down quite a bit. Removing then replacing the charger sorted the problem and the Orange light indicated that it was charging again. By the time I got to my destination the battery was at about 50%.
On the return journey, I hooked up the phone again, turned on Google nav and set off. About 30 minutes into the journey I stopped off at a petrol station to grab some snacks, checked the battery and read 17%! Even though it was supposed to be charging the whole time!! I then got a message saying that the power from the car wasn't enough to charge the phone and I should attach AC power ASAP, which I obviously couldn't as I was in the car. I ignored it, got home safely enough, disconnected the charger and then watched the phone die .
Ok, so I was using gps and 3G which clearly uses up power and I guess Google nav is fairly processor hungry, but I would assume that having it connected to the car charger would be enough. Coming from a tocco ultra, I'm used to rubbish batteries, but at least that would charge up in a car.
Don't get me wrong, I still love the phone, but I just need to know if this is gonna be a regular issue, or something that can be sorted out with a Rom update.
Just for info, I've had my desire for nearly a week now on TMO using the old Rom. And, the car was Passat estate which is in very good nick, so I doubt that was the problem.

I would look if the charger really charges the phone or if it drains it also when not using GPS/Nav etc.
Reason I'm saying this is that I once bought a charger that actually drained the battery instead of charging it, while it worked fine on my older Nokia phone. I'm assuming the phone deactivates some power saving features because it thinks it's hooked up to a charger, but at the same time the charger is too weak to actually charge it.

I have not used branded rom before on this phone but the htc rom battery life is fine. Mine has been going for three days with usage fine

nice, 3 days. how many times u charged the phone since u got it?

intresting my battery last a day

I just started charging 2nd time my battery and it lasted hmm since about 2pm till 15% at about 00.00 which is pretty much 10hours of heavy use. i did leave it on sleep for about 2 hours though and i left it at 25% and after that it had 25-24 % lol so if you turn all the updates off it will last quite a lot i guess

I rang up T-Mobile today (tech support) to ask about the lack of update considering the rom was behind the non carrier phones at the start and then an update too. They said they do work on them when they see a notable difference worth updating.
Anyway, I also said I was incredibly dissatisfied with the battery and how long it lasted and wondered if it could be to do with the ROM being well behind the stock HTC one. The tech support guy was excellent and very helpful. He said that with the type of battery in the Desire, you need to make sure you have it on a MAINS charger from quite low for a good couple of 14 hour sessions with the phone off. This builds up the charge for the battery and you should see a marked improvement. He said that most people don't bother to do that and as a result get poor performance.
He did say him and 4 members of his team have the same phone and while some of his team had battery issues he didn't. The main reason being that he had spent a few days not taking it to work and running it down in the evening then giving it three 14 hour chargers. He said that made a huge difference.
He also said if I was dissatified to a point of big frustration they would replace the phone or refund. Can't ask fairer than that

Tired of my Evo poor battery

My Evo has been Pissing me off. It dies in less then 4 hours of use and if I don't use it and leave it on standby it dies in 6 hours.
I just got it six days now and I wish I had my hero back again. This phoenix is really ridiculous and since I got the 2.2 update I can't do nothing to try and kill start up programs and nothing.
I'm thinking about ending my contract with Sprint and get something like the Droid x cause I'm not into the epic 4g at all. I know the hardware is better but I check the roms over that side and I'm sorry. There garbage.
How are you stock 2.2 guys doing with battery life and what do you recommend me do to get batter battery life. I already turned off everything as in gps, Bluetooth.4g. Everything except data. I use ny data. But I don't think j could take this any linger.
I'm at 61 percent and I have been plugged out for 2 hours now. Someone has any advice?

Dang... I normally get around 10-12 hours of normal use. The only time I get 6 is if I'm streaming Pandora over 4G all day. Have you gone to the Sprint store and complained? That sounds like a bad battery.

Sounds like you didn't charge it correctly the first time. I get over 24 hours of standby and occasional calls or about 8-10 if im listening to music all day and browsing the web and I'm on stock froyo.

I got it two days used cause there's none in ct. And they won't have any more Evo for 2 more weeks. And no one has a battery. I told them that the hero used the same batter and nothing from no one.
I called them last night and they said to bring it on a Sprint store to get it checked on. I told them to send me another battery. And they refuse they rather replace the phone with a refruished phone. Even though the phone is 6 days old.

Have you Rooted yet???
I am running Freak E Froyo version 1 from Yay 4 Juggs and have had 2 days of extremely long battery life. right now sitting at 19.5 hours Up time with 36% left and 2:10 hours awake time. Yesterdays was well over a full day of my average use.
I would post yesterdays picture of the status but the pic is still on the phone and I am waiting to plug it in after work today (9 more hours).
I do believe it has to do with the Kernel you have and how use set it up in SetCpu.
I was in the same boat you are in, I know how you feel. I have read about a few other ways to charge the phone and letting it fully discharge too that might help.
Just don't expect Best Buy to get you a new battery, I've read that they are sending out knock-offs that are lower quality and Mah (something).

Do you have low signal levels? The evo eats up the battery looking for a signal.
Sent from Evo 4g

I can't root cause i have the Froyo ota on my phone. I got it pour that so I can't root but I really want to.
What do you mean lower quality battery. Can I prove thus somehow.
Also I do have poor signals sometimes so I turn off 3g and trust it doesn't help at all. I'm not at 49 percent. My phone has been in my pocket since my last post

Im going on a guess here but he said he had his EVO for the past 6 days . Im also gonna guess his phone came with 2.2 Froyo on it . There might be a possibility it has the messed up Facebook app on it that is causing the drain if he used that . I would take your EVO and do a hard factory reset . Just back up your contacts to gmail before doing the factory reset . I would also pick up a battery from sprint so you are setting everything back to the beginning . Fully charge the new battery and give it a week . I noticed with my stock battery that after a week life seemed to improve . If at the end of the week you havent seen any improvement then I would say bring it back terminate your contract or get a new phone . Your choice and good luck .

I'm going to take your advice. But they fixed he Facebook issue I believe. I can reset everything and see what's up though.

Even with out root you can still do a few things to tweak the battery. Just search the board

JuiceDefender works well for me by intelligently scheduling when data is connected, but if you have low cell signal (like one bar all the time), your phone will crank up the voltage to your antenna to keep a connection open. There's not much you can do about that kind of battery drain.

They fixed the issue but did you download the updated Facebook app ? Thats the only thing im concerned about . I noticed after getting my Froyo update my battery life dropped off as well . I performed a factory reset ,Settings> SD & Phone Storage >Factory Data Reset . Reloaded everything put the phone on the charger and charged the battery to 100% and went from there . On average with my phone use I can get anywhere from 24 - 32 hrs sometimes upwards of 48 . Mind you I dont use 4G since I dont have it in my area. I live 3G on and check my weather and email randomly through out the day as well as use my EVO as an mp3 player at the gym . It seems the phrase "Your Mileage may vary" applies very well to this phone LOL

I am in a similar situation. I can get at least a day out of my phone using it however I please aside from gaming all the time. Coming from a Palm Pre, that kind of life is awesome.
I also have setCPU set pretty aggressively. When the screen is off it sits at 200mhz. When on, it's overclocked as far as it will go.
When I don't call much or use it for the net, I can get home after work (4am to 3pm) and still have about 70 percent battery.

[Q] Terrible Battery Life - Hardware Fault?

I've had my new desire z about 2 weeks now, and am utterly dissapointed by a frankly dreadful battery life.
It's my second DZ, given the original was nicked, but (kicks self) wasn't insured, so was purchased from a supplier that shipped my phone from Hong Kong (I live in UK, and the new phone is an identical model, except for a slight difference in key layout - A2727 I think is model number)
The original phone would give me over two days life with very low use, which i considered to be fair for a decent smart phone.
The new phone barely gives me 10 hours with no use. I've done a couple of tests - unplugged it at 2am, but 8am it's at 30% or lower. This was done with all data connections turned off.
If i leave the new phone to go dead then that's it - it won't charge. The only way i've found to get juice back into the battery is to hold it in my old touch-pro 2 until it's charged enough to charge from the desire.
Last night was the clincher. I've gone out with some friends to the pub. I had a conversation over it, and checked my battery life - 42%. As a last dith effort i factory reset the phone at that point to rule out a mischevious app, and checked - 39%
Within 2 hours, and with no use at all that was down at 8%. In order to avoid the charge issue i cut my losses and turned it off at that point. Once home (oh, about 4 hours later maybe) I was unable to turn it back on. I then left it plugged in overnight, and was still unable to turn it on this morning until i'd done my cross-phone charging trick.
I'm now entirely convinced there's some form of hardware issue at fault here, so i'm wondering if anyone else has had the same problem with this phone before? I see lots of thread regarding poor battery life, but most seem to be solved by turning data off or some rouge app, neither of which are an issue in this case. Also, any hints for making my life easier when I phone HTC tomorrow? I've read elsewhere their support might not be all it should be.
Thanks in advance for any help! I've ready to pull my hair out as what is a fantastic phone otherwise has been completely ruined by this battery issue.

I think you should get a new battery to rule out that the battery itself isn't a problem. I had similar issues with my G1 a while back and it solved a lot of wierd, seemingly unrelated problems. Batteries are pretty cheap online, $15 or so and some are free shipping.
The way that I figured out my battery was toast was by comparing it to other batteries. it had a bulge in the center where it should have been flat. Fingers crossed it isn't hardware.

had already tried a diff battery (did you know you can chew a corner off a touch pro 2 battery and make it fit??) Which i know worked fine in the old nicked dz and imo as i was getting same issue ruled out battery problem.
anyway... phone has now been returned and i'm waiting 2-3 weeks to get it repaired under warranty (though am hoping for complete replacement obviously)

Chewing on batteries has got to get you extra xda brownie points. I'll remember that

I'd like to think there was some techincal or engineering skill in there somewhere.
but it was mostly "Well, apart form this nugget of plastic they're the same shape..."

I'm having the exact same problem... When you take you shutdown to recharge a dead battery, does it sometimes try to turn back on? I left my apartment like 30m ago with 100% battery, and I'm at 84% and declining. There's nothing running. And I've replaced the battery, same issue.
I think I might just RMA this one.. seems like an engineering issues.
Edit: I'm the 40 seconds it took me to type this, battery dropped to 82%.

Wanted to bump this post. I've since wiped / reloaded and wiped battery stats. It's still jacked. I think it's an internal electrical thing. Reason is: I'll power down to take the battery out. When I put the other one in, it'll turn back on. Or if I power down to charge, it'll turn back on - plugged in or not. I don't want to deal with the RMA process again, but I think it's my only choice. I've taken two phone calls this AM @ 100%, and it's at 96% now. Drives me insane. Ugh... I'll call TMO. Anyone know if the replacements are still rootable?

So... I had my phone replaced, and it's still doing the horrid battery thing. Flashed CM 7.1 RC3 or w/e the latest is, cycled one battery - and it drops like a stone. I have two chargers (one at work, one at home) and they both charge the phone up to 100%. But it's still losing battery life quicker than I'd like. I used to be able to get a good 18 hours out of this phone. Even with a new battery and a new phone, it's acting up. I'll try to flash an older ROM and see if it's the same thing. I updated to #130 nightly from 7/10. We'll see how it lasts today. But I do remember I had horrible luck with CM's ROM's on my G1. Battery would just drain for no reason. The main process taking up the most battery life is "Cell standby" so I changed to the latest radio - and it still drops. OP - have you figured out your problem? I've removed a ton of apps, and it's still messing up. I listen to music for... 45m in the AM, and I get down to 54%. I've formatted my SD Card as well.. it's driving me insane.

I just flashed CM 7.1 a few days ago and while the ROM is great, it does seem to be a litter harder on my battery than 6.1 was. With light/moderate usage yesterday, I got about 16 hours and that was running the battery almost completely dead. With heavy usage, I get about 10 hours and need a bump charge in the afternoon.
You might want to look into getting a Mugen 1800mah battery. You can get them on Ebay from 35-40 dollars. The seller 'nakedcellphone' is based out of Southern California and another user has confirmed ordering from them and getting a legitimate battery (lots of fakes on Ebay). Either that, or carry a charger with you...
Have you tried using Watchdog to see if there are any 'rogue' apps that are causing the drain by running in the background? What about going to spare parts > battery history > Partial Wake usage? There it will show apps that are draining your battery when you're not 'actively' using your phone. For me, the Android System is the highest drain in that menu. Good luck! Hope some of this helps!

I just checked spare parts, and there's nothing too odd in there. Just my music app. And I've changed that too - thought Winamp was killing me. I'll check Watchdog. This is a brand new OEM battery along with an RMA'd G2. It has to be the OS / Radio or something. I've stripped like every non-essential app too.

Overnight battery drain

I thought I would check and see how much battery is used overnight on my Nexus. What I found was that the Android OS kept the device awake over half the time. Also, for some reason the phone used battery as well.
I'm running stock 4.0.2, rooted and unlocked... is this typical?

Yes, this is known bug:

Don't forget to star that issue ...
And tell all your neighbors ... all your friends to star it as well.
Spread the word ... tell the universe ...
Google must fix this!

Hey Guys -
I shut off location services and my battery drained only 9% in 8 hours of non use last night... It used to be around 25%. I'm thinking that Android keeps waking to check where you are... Just shutting off GPS is not enough as it will wake to find your location via wifi or cell towers.
Just my 2 cents. Give this a try to see if that helps you guys out. Google still needs to fix this but it might be a good temporary workaround.
Rob

I typically see around 8-10% battery drain overnight off the charger. And I thought I had problems. If you are losing 25% over night that seems unacceptable.

It actually dropped from 100% to 24% overnight which is almost 10% per hour.

i lose 1% in 1.5hrs, on standby in ATT HSPA+ network, i thought that was pretty good.

Roman has fixed it or at least it appears he has. I loaded his CDMA rom "[ROM] [AOSP] Android Open Kang Project - toro build 9 [Dec 21]" over at rootz and it is putting the phone to sleep when the screen is off. My phone had be staying awake 30 - 50% of the time prior to this. I've only had the rom loaded a short time, but in the last 40 minutes of non-use my Staying Awake time has been about 2 minutes. YMMV
Good luck.

Thanks for the reply... that's encouraging to hear. I'd like to stay stock for a while so hopefully 4.0.3 drops soon!

I know many people recommend rooting and using a custom rom, but I've had a poor experience with that. Having said that, I've been working on battery issues and this is a picture of my battery drain overnight. It basically took a nosedive.
What I don't understand is some people are getting great battery life from this phone. I've turned off all my widgets and followed many recommendations - but frankly I shouldn't have to do any of that and even so my battery life is abysmal.
Is there any answer to this problem short of rooting? Do I have any reason to believe that google will acknowledge and correct this issue?
By the way I had a Droid Razr for a month prior to the Nexus, and it would lose no more than 10% of it's battery overnight.

I do everything "wrong" (syncing, gps - wifi - data on) I have 5 widgets on my home screens and I loose less than a % per hour over night if not on the charger.
When I am using my phone I keep the screen on full brightness. This will get me about 12 hours of use with 4 hours screen on time.
I have no idea why some people get great battery life and others don't. There must be bugs floating around. Lets see what 4.0.3 brings. I'm unlocked and rooted but still stock.

That's the frustrating thing - it's working great for some people.
I have to return mine because the headphone jack doesn't do stereo, maybe I'll get lucky and the new one won't have signal and battery issues.
The Razr never dropped voice or data - the Nexus drops both multiple times during the day.

I would try a different radio. I wasn't exactly thrilled with reception at first. A North American radio changed that. But i would still give moto a step up on reception.
I think more people should also consider congestion in their city to how well battery life does. Can Make a big difference. Otoh though, that doesn't account for standby at night when you're asleep. It would seem to me no matter how your phone is setup 1% an hour should be the norm, unless your phone downloads a lot of data.

Ya, try swapping it, IDK... I have yet to drop a single call on my Nexus. One thing i can say is Samsung needs to look at their quality control. I definitely got a good one. I don't see the REAL problems others are having. The fact that most phones are fine, and some are duds is the one thing i will hold against Samsung. Gives a really good phone a bad name when so many have issues.
I can say its not all of them.

I know many people recommend rooting and using a custom rom, but I've had a poor experience with that. Having said that, I've been working on battery issues and this is a picture of my battery drain overnight. It basically took a nosedive.
What I don't understand is some people are getting great battery life from this phone. I've turned off all my widgets and followed many recommendations - but frankly I shouldn't have to do any of that and even so my battery life is abysmal.
Is there any answer to this problem short of rooting? Do I have any reason to believe that google will acknowledge and correct this issue?
By the way I had a Droid Razr for a month prior to the Nexus, and it would lose no more than 10% of it's battery overnight.

Thats just horrible idle drain. Something kept it awake you can see.
I feel bad cause my gsm version is literally the best idle drain phone ive ever had. It stays dead flat for me and last night i lost about 1% every 2 hours, and tgat is witg data on and two gmail syncing etc. Its just awesome. I think there is something wrong with tge verizon model. My phone is stock too.

Is it related to wifi? Noticed most of your drain was while wifi was off.
My grandma beat me down and took my nexus. Sent from a jitterbug with beats by dre.

I just tried a new ROM last night and had an improvement with my phone sleeping more of the time the screen was off yet the battery drain doubled to 3%/hour. Can someone explain how that makes sense? My phone slept 10 of 11 hours during this time. And the CPU was scaled down at 350 mhz by the kernel the entire time while the screen was off. So confused...

Might need to calibrate battery.

i have the same setup and loose less than 1% an hour, when the phone is idle

Thanks to the kind folks who have replied with questions, comments, or just sympathy
There are of course a lot of threads in this forum related to the Nexus battery life and I've been trying to do my own due diligence. I have removed every widget from the phone - even those which are just 'switches' and should not make any data requests. It was still draining.
Then I removed the fancy Light Flow lite app that gave me pretty notification lights - still drained.
Finally, I removed Battery Monitor Widget - the very app I was using to try to find the cause of my drain.
Took the phone off the charger at about 10:30 this morning. Used it for navigation for 20 minutes, ran the bluetooth for a bit and that took quite a bit off the battery. However, when I got home I forgot to turn the wifi on and set the phone down. Sitting there doing nothing connected to 4g the battery dropped less than 10% over three hours. I didn't look closely enough to see the exact numbers but overall I'm at 60% now after 6 hours of what I would call moderate use.
Most importantly, the phone seems to actually sleep now when not in use. I don't mind if the battery drops a bit faster during use - it has a great screen and wicked fast 4g. I just don't want it to tank when it's not doing anything.
For right now, it's acting exactly how I would expect and I'm very pleased. Will probably give it another day and then try to add back my beautiful widgets time/weather/calendar widget on the home screen and see what kind of damage that does. Maybe try a different battery widget as I like the percent left in the notification bar.
Good thing is, now I have a baseline that I'm happy with to measure my performance from.
Thanks again for those who've posted in this thread. Hope anyone else having similar issues might benefit from my experience.

And I'm right back where I started. Phone had insomnia last night. I took it off the charger at 100% last night at midnight and it died within five hours sitting on my night stand.

If your battery drains fast, charges slow, and top left corner of phone is hot...

Quick story that may help some other people:
I bought my Verizon Galaxy Nexus used on Craigslist. It was a good deal. Right away I bought the extended OEM battery as well as the Seidio extended battery. The first thing I noticed was that battery drain was unusually fast. I'm no noob to Android phones, and a few of my prior phones had bad reps for battery life (HTC Incredible, Samsung Nexus S, HTC Thunderbolt), but this was something special. For the first time in my life I felt the need to use Juice Defender, and that was only marginally helpful.
I never minded with the other phones because I would use the largest battery available, charge on my 40 min commute to work, charge on the commute home, and everything would be fine. The problem with the Galaxy Nexus is that not only would it drain fast. It would take unusually long to charge, espcially when using during a charge.
The next thing I noticed was that the phone was getting very hot, especially in the top left corner, even when it wasn't doing much. Turning off LTE seemed to help but not much. After a couple months of use, trying ROM after ROM, kernel after kernel, reverting to stock, etc, things took a turn for the worse. I would go to sleep with a pretty good charge and wake up the next morning with a dead battery. Sometimes the battery was so dead it wouldn't even take a charge.
I called Samsung, and they were very responsive. Even though I wasn't the original owner and had no proof of purchase, they paid shipping both ways and had my phone repaired and back in my hands within a week. The paperwork that came with the repaired phone just said that a "component" had been "replaced". I called and asked them which component was replaced, but they couldn't give me any more details than that.
My repaired phone gets warm sometimes, even very warm, but I haven't noticed that hot upper left corner. Meanwhile, the battery life is night and day better than it has ever been. I can get through the day fine with the Samsung OEM extended battery, and the Seidio lasts damn long like it should but never did. The batteries now charge much faster as well. I can finally enjoy this phone like it's supposed to be enjoyed, and I have no more thoughts about upgrading some time soon.
Maybe Samsung just has amazing customer service, but the speed with which they handled this as a warranty repair makes me wonder if this is a known issue on their end. In Googling for a solution to my problems, I came across other reports of people who found their battery suddenly dead, unable to take a charge.
Here's my advice: If your battery life is atrocious - and I mean atrocious even with the screen pretty dim, no accounts syncing, LTE disabled, factory stock with no apps installed...
and you find your Galaxy Nexus taking a long time to charge (using the OEM charging cable)...
and your G-Nex gets super hot in the upper left corner even when it isn't doing anything...
then try sending it in for a warranty repair. The phone I bought on Craigslist was defective, and after struggling with it for months, all it took was a one week repair and I'm 100% content. It's a completely different phone.

:good: glad you got it fixed

I've had the exact same issue recently, phone would get extremely hot especially with the screen on. Never had it not charge, but it would never stay at 100% very long while charging. Screen on time was pathetic and usually not much more than about 30 minutes.
Today, I decided on a whim to completely drain off my battery, phone wouldn't even turn on when I was done. Recharged to full with it off and it's running cool as a cucumber. 7.5 hours since I took it off charge and an hour of screen on with a bit of streaming over LTE and I'm still at 53% battery (whether that's good or not is questionable, but it's a massive improvement for me.)
Am I positive that's what fixed my phone? No, not at all. If it starts acting up again I'll probably talk to Sammy about a replacement, but for now I'm happy.

that's kinda bit questionable still. just an hour of screen time and almost half of battery means there's still a huge space for improvement

Almost half of that was streaming on LTE and in general being an attempt at eating battery and causing the heat issue to come back. Coupled with the fact that I live in the boonies and my signal is never stellar, I'm fairly happy with the time.

Good to know

Totally different outcome for me...
I had the exact same issue; slow charging, horrible battery life (even after a new battery and a factory reset). After two weeks without my phone, today I got it back. Not only did I get the same phone back (based on the serial number) I got the *same battery* back. This was also the result of a "replaced component" (which no one could tell me what it was).
edit: I should add, I bought this phone new from Google directly. It worked great from May until September when this problem suddenly started happening. Prior to September, I could easily get 2 days out of a charge with my typical usage. After it broke, I was lucky to get 8 hours, even while the phone was ~80% idle. You can see in the screen shot that the phone was burning around 8.8% an hour even while completely idle. I mentioned all this to the person who created the service request, but obviously that didn't make a difference.

I'm so disappointed, but I'm not even sure where to start. I will not go without my phone for another two weeks. I'm going to call tomorrow and see what they'll do, but for now I'm more than a little pissed off.

I'm on my third GN and they've all had this problem I replaced the first 2 directly from Sprint. Pretty fed up with the phone. Friends of mine have this phone and don't have any issues at all... what are the odds that I were to get 3 defective phones in a row?
I'd consider going through Samsung for warranty, but I can't go without a phone for up to 2 weeks.

Sorry you two have had such a bad experience. My replacement Nexus continues to be terrific. While my Nexus was in the shop, I used my old phone (Thunderbolt) and enjoyed the change during that time.

Samsung tech sux.. i had the samsung captivate glide sent it in 2 times and they have yet to fix the prob.. the first time i sent it in they replace the main board, and when they put it back together they drove a screw up through the keyboard.. and still sent it to me like that.. the second time i sent it back, i mentioned what they did to my phone, they said they would fix it but they didnt..
Samsung is the worst.. bla bla bla

I read your story but immediately figured out the problem. If you charge the phone only on the car charger, you'll have problems. Most of the time it affects the battery though

I too never used a car charger, I don't even own one.

phone number?
I too am having problems with my galaxy nexus, its burning threw battery almost one or two percent every 2 minutes, even while phone is on idle, is there a number for Samsung you can provide that I can call to see if I can fix this problem?
