Battery Reporting Problem - Samsung Galaxy Nexus

Hey guys!
I'm brand new with the galaxy nexus! I just came over from the Atrix 2 forums, and am really enjoying the phone so far! Anyways, i have a really peculiar problem that I can't find the root of. Say after 8 hours my phone will be reporting around 50% battery. If I restart for any reason though, when the phone boots again the battery percentage has dropped significantly, Usually to around 15%. Even after wiping battery stats and doing a clean wipe I'm still having this issue. I've experienced this on both AOKP and CM10.1 nightlies. Any ideas? Thanks!

It is a bug we have over at the n4 as well, 4.2.1 doesn't report the battery accurately. It'll not drop for several minutes past the ~5,5 minutes per 1% increment for regular screen time in order to then suddenly drop 2-3 % in seconds. A reboot can set it back 5-15% of battery, shocking but not a true value.
Hopefully 4.2.2 is around the corner and is fixing all that.. :good:

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.

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.

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...

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.

Sudden battery drop after screen freeze, calibration won't help

Hey guys,
First of all: i'm sorry if there already is such a thread, i was unable to find any solutions after several days with hours of googling for anything that could help.
Anyways, here is my problem:
I bought the Galaxy Nexus (Maguro, GSM-Version) a few weeks ago.
It worked all fine and i didn't flash it until CyanogenMod 10.1 came out with the monthly M1-snapshot build. So i flashed that and it all worked pretty well, no freezes or problems with the battery or whatsoever.
And while i was on that M1-build, i was playing around a bit too much i guess, because i just deleted the battery stats in the CWM while the phone had about 40% of battery or so.
And then it happened in the following days: when i was at about thirty percent of battery, the screen froze and i had to pull the battery in order to reboot. after that the battery level dropped to like less than 10%! and sometimes the percentage would even increase for some hours and then drop normally afterwards.
After i tried several ways of calibrating the battery with no success of solving that problematic behaviour, i flashed the original stock rom with the nexus toolkit.
On stock rom, i had no such issues and tried to flash it once more with the allegedly stable SlimRom. and it seemed to be working, but yesterday and today too, i experienced that screen freeze once more with an immense battery drop all of a sudden.
I'm seriously annoyed with all this and i would love to be able to solve this problem. I regret deleting the battery stats in the CWM, but i just can't believe that this is the reason for all this...
Thanks a million in advance!
Maybe someone lives in Berlin/Germany who could help me out with this?
As far as I know, those battery drop happens on any rom when a screen freeze occurs . Although I seldom have screen freezes, once in a while it happens to me also, that sudden drop in battery percentage . Especially when trying out new rom-kernel combo's.

So you mean, that happens because of not so stable roms rather than bad battery calibration?
I mostly noticed such a freeze when i wanted to launch Google Now through sliding upwards from the homebutton while i was using another app
it's just so weird...
would you suggest to just wait for the stable cm10.1 release?

Battery Hardware Issue

Hello,
I received a AT&T Galaxy S III from Best Buy after my initial one broke. After I received the new one, I put CyanogenMod 10.1 on it and got horrible battery life. I bought new batteries to see if that was the issue and I got the same results. The battery would drop about drastically, a charge lasted about 2-3 hours with minimal use. I wiped my cache (a dalvik cache), cleared my phone, and installed SlimBean on it. After that I got the same results (I don't have a ton of background apps or anything). Should I assume this is a hardware issue since I am using new batteries and have tried two different ROMs? Is there anything I can do to fix this?
Thanks for your help!

There is an issue at the moment with recent cm10.2 based builds not going into deep sleep. Load the deep sleep widget and see if your phone is going into it. If not, you have this issue. See my other post for suggestions. (Turn off Location Sharing/Wifi and SystemUpdateService).

Thanks! I just downloaded this, but I'm not sure how to interpret it. What percentage am I looking for? It says 64% now.

64% is good. It means its not the deep sleep issue. You want that percentage to be as high as possible. Deep Sleep is the lowest CPU state available while in standby. I'm battling an issue on Paranoid Android where I'm getting 1 - 2 % deep sleep.
Better Battery Stats will give you an idea if one of your apps is running out of control. But my immediate guess is that with 64% deep sleep you're running about right. What do you do in those 2-3 hours? What is your coverage like? Minimal signal may give you weird results. (Sorry, I have to wait 5 mins between posts)..

You have to give the phone a little time to settle out too. Any new installation of a ROM or new device takes a little while to build all the caches and work through the background syncing stuff until it settles out to low consumption. How's your cell service? When I have little to no reception my phone tears through battery life while it searches for signals. Wifi will do the same thing too, just to a smaller extent.
Let your phone get down to the point where it needs to be charged (<10%) and take a look at your battery stats in the system settings. Post your time on battery here, and also the top 3-4 things that are consuming your battery with the percentages. Click on the "screen" and let us know what your screen-on time is as well.
That's probably a good place to start.

Battery Sudden Drops

Dear all,
Recently my Note is facing a weird problem. While my son is playing a game, the battery drops 20-30% in 10 minutes. If I shut down the tablet and re-power then the battery goes to normal again.
In the battery stats I can see a huge drop during game usage and then up again on reboot.
I performed a factory reset but the same happens....
I flashed the Kit Kat via Odin.... but the same
Any ideas?
Drain the battery down to below 5% then charge it to 100 and it should be fine. It happened to me once and after a full charge after a full drain it never did it again

This is what worries me.
I drained the battery and charged it fully powered off. It did it again. I drained the battery and charged it fully powered on. It did it again.
If I'm using it for browsing, papyrus, images etc its fine. This happens only in games and when i reboot the battery percentage is ok again.
strange....

I had the exact same problem as you are describing but additionally, my overall battery life wasn't lasting as long as it should either. I ended up sending it to Samsung's repair center to get fixed. I'm not sure what they did but some other people on the forums suggested it was a motherboard issue.
So the capacity of the battery seemed just fine but the readings were crazy (dropping from 50 to 5 in minutes and then on reboot back on 50).
After 2-3 full cycles of charging nothing changed. Flashed fw nothing changed. Went to Samsung service and they just informed me that they changed the battery and now performing final checks.
Hope this will solve the issue. I'm too lucky that I am in the "6 months warranty" window for battery...
How does one go about sending it into Samsung? After getting it back, did you see a significant change?
I've been debating doing this but wasn't sure how to go about it.
I haven't got it back yet. They just called me and they said that apart from the battery, they need to change another part (the telephone operator didn't know which part) and I'm going to receive it tomorrow.
So I'll let you know once I receive it.

After trying everything (flashing different roms via odin, factory reset, full battery cycles etc) the problem never went away.
Went to Samsung service. They checked the battery and had to replace it.... within the warranty.
Same issue here. Just got an email saying its fixed. They changed the charging port and lcd. Weird that they replaced the lcd.
Well I got it back. Seems they broke the s pen function when taking it out or putting in. The tablet thinks it's always out of its slot. I guess another 2 weeks without this thing. What a pain in the ass. Times like this makes me wish I bought an ipad where I could just walk into the store and get it fixed that day.
I had the same problem. I sent it back on Monday and got it back 7 days later. They did not say what they changed, but now everything is working fine. I even got a new usb cable and a magnetic Germany flag
I sent mine in for an overheating problem and they changed the charging port and gave me a new cable. I initially also had the random drops in battery but seems to be better now.. They said bad voltage going to charging the battery or something. Still have overheating so gotta send it in again?

So guys did you get it fixed? I have exactly the same problem. I have sent it to fix at the sam service - they changed the charging port, but it didn't help anything. 1,5 years of normal usage and now I can pretty much throw it into the toilet. God damn POS!
Galaxy Note 10.1 2014 battery drops
Hello all,
Just wanted to inform you all that I have been experiencing these battery drops (yesterday from 93% to a mere 5% in a matter of minutes) for a very long time now. I am running under the latest 4.4.2 stock firmware.
Also, battery life is way below par (understatement !), where the Note sometimes drops to around or below 5% (the magic number below which the screen starts to dim pretty dramatically and there's no way to influence that)
Funny thing is that after the battery drops to below 5% or even 1 or 2%, it's still possible to use the tablet for quite a number of hours afterwards, which suggests it may be something with the logic estimating/determining the remaining battery capacity, rather than the battery itself....)
Now I've tried draining the battery and fully recharging it multiple times/ resetting the stats using free apps / revert to factory settings etc.
All to no avail unfortunately, this problem simply keeps coming back.
(By the way: Apart from the battery and battery life, the Note is an excellent device, and delivers as promised.
Please also note that charging it through the microUSB cable is also simple, stable and relatively fast, unless you compare it of course to my all new Samsung Galaxy Note 4, which has a superior fast charge mode and offers the highest possible battery-life at this moment and easily beats any other smartphone (including the usual suspects from that Cupertino-based firm of which I can't force my mind to remember the name of.....) in this price-quality and performance category )
As for warranty:
Battery is no longer under warranty, the device itself is.
As such, I will now get the battery replaced by a new Samsung OEM-battery first, and see if that resolves the issue.
If it doesn't help, I will send it in for repair for Samsung.
I will keep you all informed on the resolution and cause.
Likewise, if there's anyone that has gotten to the root cause of this issue, please let me / let us know
Some users reported some 'magic part' OTHER than the battery itself (motherboard / charging circuit or even the lcd ??) having been replaced by Samsung after sending it in for repair.
That information could be very valuable to us all in trying to get Samsung to resolve the issue, so I would really appreciate it if someone would share this info in this thread.
Hey I know that there hasn't been much activity on this particular thread, but i too have been experiencing this problem for over a year now. I sent it into samsung twice and it still never fixed the issue and by the time i was going to send it in the 3rd time it was out of warranty. I personally removed the back cover and unplugged the battery for a while and that did not help. I have tried flashing different ROMS and kernels to no avail until last week. I flashed Temasek's Unofficial Build found here http://forum.xda-developers.com/gal...t/lt03wifi-temaseks-unofficial-build-t2980604 and after 3 full power cycles i have not had a single random drop yet i even managed to go 3 days with 6 hours of screen on time which is a record for me with this device. Not sure if it will help everyone but this seems to have solved my problem and i am thrilled! Also (as embarrassing as it is) i played 2.5 hours of Clash of Clans straight without a single random drop either.
I am beginning to have the issue as well on my P605v. Has there been any progress with your battery replacement? @mroset

Hello KwestJones,
I've successfully replaced the battery in the Note 10.1 2014, and it has improved things. With a little care, this is easy to do. Just removing the battery connector is a bit typical, you need to lift it carefully and slightly to remove it.
The result is not as drastic of an improvement as I would like to have seen, but at least the sudden drops in battery capacity percentage seem to be under control now.
I am doing a video test now, and will see how it behaves and let you know.
BR,
Maarten
Very curious to hear if replacing the battery corrected this issue. I've been experiencing this same battery drop issue for 2 or 3 months and the unit is well outside of warranty. Hoping there's a simpler fix, but willing to replace the battery if that will work since the tablet itself is still a great unit.
Complete factory reset should clear the Android Coulometer's data base or learning algorithm. Just clearing options of Battery Monitor Widget for rooted devices won't help. There are some other apps, which seem to help if the charge level never reaches 100%, a related, but not identical problem.
I have an old tablet suffering from this, with a tweaked custom rom, and i didn't want to clear and setup that completely. The algorithm or database is "learning" again, and the capacity jumps have become fewer and smaller over the last months. It should depend on how long the device was used and never reset before the incident. In my case over a year.
Itvs much like my cars fuel calculator, which won't work correctly during traffic light stops. Right after starting the engine, fuel consumption can raise several liters/h, when the car don't drive, as it uses the last sampled value(every 30 meters). And you need several kilometers to drive to have these levels drop to realistic ones again. While after a long driving distance, a traffic light stop will hardly have an influence.

sudden complete battery drain

Hey folks, I've had my Moto Z Play since November of 2016, and so far have been enjoying fantastic batter life - generally around 8 - 10 hours over 2 or 3 days.
However, I had a nasty surprise a couple of days ago.
I charged the phone to 63% before I went to bed, and then turned it off. When I turned it on in the morning, it drained over the course of around 5 minutes (browsing reddit using swipe) to 14%. By the time I checked what was going on it was at 9%, and it had reached 7% before I decided to turn the thing off. Fun times.
I plugged the phone in with it still powered off, and it leaped straight from 7% back to 63% reported charge. Mighty strange eh.
I've not had this exact issue again, but I am concerned as my battery life seems to be significantly reduced when I compare it to before the incident. Watching youtube videos I am draining about 1% / 5 minutes, as opposed to the 1% / 10 minutes that I was getting previously.
There don't seem to be any rogue apps running, and I am slowly uninstalling anything that was recently updated, although I feel this is unlikely to be related to the issue.
I am unrooted, running the nov. security update in the UK. I have been charging using an Anker brand cable and power brick.
I was wondering if anybody else has had a similar issue to this? Thanks for reading, have a good day people.
With it jumping back up I'm thinking it's a software glitch. I'd back up my data, do a full data wipe /factory reset and see if that helps. If not, then time to call up Lenovo for a warranty repair.
thanks for that - yeah I agree, reckon I'll wipe and see how I go for a week or so. I bought through a good retailer in the UK, so hopefully getting action on a repair shouldn't be too much of an issue if it comes down to it.
Without much knowledge of how the technology works, it sounds to me like it's either a software glitch as you suggest, or potentially a bad battery.
Yep, those were my first two thoughts. Good luck with it!

I was on a pace to get something like that yesterday - but I had to go to sleep so I could get up for work. Had 8:40 SoT over 17h off charger, with 46% left. If I could have stayed awake all night I might have made it! ?
