[Resolved] Battery acts weird - increase in percentage when unplugged

Hey, I'm new to XDA (I have read rules),
My brand new device (I have it only a week and half):
Nexus 5 D820 310K, 4.4
I felt once big bump in battery percentages (52%>>28%) on 4.4.2 after a restart of my device. after this incident I noticed few more small bumps (3% jump to 4 and back to 3...)
First I blamed 4.4.2 so I flashed 4.4 and calibrate the battery, here what GSAM reports now:
when it reached to 60% its started to jump between 60% and 61% five times in 17 mins
on 13% its start settle to 12%>>11%>>12%>>13%>>14%
after both cases it backed to the normal route of decrease until the next time..
*I ignored the lack of indicator of the 28% and 59% in GSAM. (its a bug as far as I know)
Is my battery defective and I need RMA?
How can I be sure its the battery's fault and not in the chip which monitor it? (May the monitor is built in the battery?)
if its the battery's fault Brand new battery can help instead of RMA?
Thanks!
***I tried to search but I couldn't find anything but it:
http://forum.xda-developers.com/showthread.php?t=2550689&highlight=battery+bump
and It's lack the answer I need.

have you tried wiping the cache from the stock recovery or even possibly a factory reset (also from recovery)? i'd start there before i'd consider an rma.

^^
When I flashed 4.4 from 4.4.2 I have opened the bootloader in the first time so I actually totally wiped my device include cache - Am I right?
If this wipe is "count" it haven't helped me...

its normal behavior.
and sometimes when using the phone heavily, the battery % will drop, then when you put the phone down, youll notice the battery % rise slowly. thats not the phone, but the coding for the battery stats. its always been that way on android, ever since the first g1.

^^
Are you sure? I have never noticed similar incident on my nexus 4/7

yes. the past 5 years of android ive seen it too many times, and have had fun with it many times(ghost charge). its very common when flashing mods to see it occur, and when benchmarking at high cpu speeds. but it happens often after a plain old reboot as well. it "ghost" charges ti make itself accurate again when its not accurate.

I noticed last night my battery tanked. I didn't even use my phone. I'm very conscious of my battery life and I monitor it often. So I had no notable wakelocks at all. Battery dropped from 95% down to 45% within a 3-4 hours idling. Less than 10-15 min screen on time.
Odd thing was, I plugged it in the charger and it charged back to full within 20-30 min. Something definitely is up with the percentage readouts.

So what you say is that's luck that I haven't noticed same phenomenon on my other devices?
By your permission, I would like to some more opinions
May I just freak out after the giant drop in 4.4.2 and 4.4 is ok... - anybody felt similar drop on 4.4.2?

I noticed this on the first two days of owning my N5. I updated to 4.4.2 straight away and then saw the slight increases on the battery report. I'm running stock and it only happened on the first two days. I love this phone but man do I miss my GS3 and 4400mah battery.

Well, Am I the only on to notice this kind of problem?
In the past few day I haven't felt big drop on 4.4 and actually the battery acts pretty good about 3.5~4 hours of screen 14 hours of standby - probably simms22 is right.
May there is something to 4.4.2 update to it? (some friends told me that their batteries acts weird on 4.4.2 too)

just so you know, i can reproduce this. its happened on every device ive had since android 1.0. on the nexus 4 it actually was a big problem for some. it would drop 30-70% for some after benchmarking, and some phones would think that the battery level went below 0%, then wouldnt boot up until the battery was removed then put back in(lg fixed the issue though). if you heard of the "red light of death", that was one of the causes. for me it would drop 30-70% after benchmarking, but never went below 1%. then after a reboot or two, the battery level was accurate again.

simms22,
Thank you very much,
after few days I haven't felt any big drops (4.4).
GSAM reports that there is sometimes small bumps from 60 to 61 and then back to 60 but its nothing serious (probably its happened on my Nexus 4 too but I haven't noticed).
We are done here
P.S.:
Do you know why sometimes I get a notification about bug report: "hammerhead-user 4.4 KRT16M 893XX3 release-keys"? I would be more than happy to know.
In addition do you recommend to re-update to 4.4.2 even though all the battery bugs started right after the update?

you get the bug report with a combo button press(i dont remember what buttons as its removed from my rom(power plus another i think). but i remember i kept getting them on my n4 until it was removed). and reupdating wont help, you can try if you want as it wont hurt either.

GS3 has a 2100 mAh battery not 4400. If you're saying you had need for and were using an external battery then what is there to miss I don't understand. Any phone can use an external battery or battery case.

heres an obvious drop then rise, just as an example. its from bencmarking at high cpu speeds. i was benchmarking, hit the cpu shutdown temp, rebooted automatically, and booted up near 80% less than the battery % was when i rebooted. then, without plugging in, the battery "magically" charged itself a bit, trying to go back to where it should be. and if i didnt keep using the phone, it would eventually equalize. this is an extreme example, but its the same as with yours. with use, battery drop, sometimes it drops a little more than it should. so it tries to go back to where it should be.

Battery drain - no wakelocks etc - possibly caused when switching wifi networks

Hi,
I normally have excellent moto g battery life. However four times I have noticed a bad battery drain. This seems to occur when I switch from one wifi network to another. Here is what happens:
1. On home wifi with battery drain of maybe 1% an hour (at most) when phone is idle (not aeroplane mode - just sitting on table with wifi active).
2. Move to a new location for an hour and use wifi.
3. Get back home and phone now drops 3% an hour when idle.
4. Even more odd - if I switch on aeroplane mode, so wifi is off, the phone still drains 3% an hour. Normally I see at most 1% drain a night on aeroplane mode.
I used 'wakelock detector' app and there are no wakelocks above what I normally see when battery is normal.
The standard battery graph shows no obvious apps as the cause, in actual fact when I put it in aeroplane mode it shows just blank lines for gps/wifi/screen/awake etc. So all looks normal for aeroplanoe mode, ie nothing is awake.
cpuspy app shows phone cpu goes into deepsleep mode (ie cpu sleeps).#
Only way to fix issue is to reboot.
All I can think is that the phone is trying to connect to the wifi network it has just left, eg when I go from home to a new location it connects to the new location BUT is still trying to connect to home as well, and when I get home it connects but is still trying to connect to the previous location.
However that doesnt explain why I still get the battery drain on aeroplane as wifi is off mode unless something is 'stuck' but not showing up in any statistics.
Any ideas? Ive pretty much exhausted anything I can think of. Phone isnt hot at all so its not the CPU (cpuspy shows deepsleep as well remember).
Ive just factory reset so I will be able to see in a few says if it still happens but Im pretty sure it will. Im hoping its a 4.3 thing and that 4.4.2 will fix it but I also think it may be hardware related, eg wifi chip doing something weird, in which case 4.4.2 isnt gonna help.
Regards,
Scott

My wifi was draining my battery also. I see in settings under wifi it is set to always remain on even when screen is off. That was keeping my phone awake for hours. I switched wifi off and not had a problem since.

Thanks for the reply. Not the same issue as me though. I do have 'WiFi when sleep' on when at home but normally that's OK for battery as I have excellent WiFi connectivity at home.

Got the same issue! No wakelocks, phone asleep, steady drain in airplane mode. Only change is I've gone to my parents for Christmas - signed into their wifi of course while I'm here.
Maybe a bug in the WiFi driver. Good to know a reboot fixes it temporarily, I've just restarted my phone after fully charging it and will see if it's behaving now.

Hi, keep me up to date on how it goes. I'm thinking not a 4.3 issue or it would be more widespread, not an app issue as no wakelocks. Must be driver type issue as you say. Pray its not hardware itself.
I'm running British retail ROM, what are you on.

It's my backup phone, a Tesco 8gb edition that I unlocked but haven't flashed or rooted. Will update when I know more.

I factory reset and reinstalled apps. My problem described above seems fixed but too early to tell for sure.
However before I reset I noticed while the drain occurred that an app called 'cpuspy plus' was behaving strange, eg it showed 30 processes in osmonitor and each process was using 0bytes of memory, and I also had hardly any spare RAM (normally 250MB free but it was down to 70MB or so).
I don't know if the factory reset itself fixed the issue or if removing cpuspy plus fixed it.
I'm guessing the factory reset did it but I'd be interested to know if you are using cpuspy plus.

Well, I had a 10% battery drain overnight (7 hours) in airplane mode... I was in my gf's parent's home and used their wifi network.
Now I did a factory reset and I'm charging the moto g again. Hope that fixes it, I'll report back when I know.

Experiencing the same problem. Not sure of the cause.
I think it is the option "Scanning always available" in the advanced wifi options

I have the same problem. I'm on 4.4.2 without root. My wifi stays on all the time since I learned that wifi uses less battery than 3G or 2G (am I right?). Also the wifi-optimisation is activated. Strange thing that happens in airplane mode.
Can someone pls report back if the issue is solved by a factory reset?

I've been having this issue too, on 4.4.2 US GSM. I went from draining 1% overnight to draining about 2-3% per hour on standby. Couldn't figure out why for the life of me either. Its been this way for about a week now, I've tried rebooting but it doesn't seem to help.

I am on an unrooted 4.4.2 US GSM and have a similar problem. I've noticed an average of 1.5%/hr discharge overnight with mobile data, and wifi shut off. I'm gonna put it in actual airplane mode tonight and see how it is in the morning. I did some tests during the day and saw that the phone was awake with the screen off for ~8% of the time (used better battery stats).
Unfortunately, with the retarded kit kat battery permissions - we can't see exactly which process is the culprit for the wakelocks - just the "catchall" power manager wakelock.

Have you factory reset yet. If not then do so as it fixed it for me and others (that's if its the same issue).

When I first noticed this happening, I reflashed the stock image, but it hasnt made any difference. I'll give the factory reset a go & see if that helps any.

Put it in airplane mode all night and had location services disabled. Here's the result, still 1%/hr drain.

Maybe someone will notice .. I'm thinking of downgrading to 4.3 somehow, so I can observe partial wakelocks and figure out the root cause.

I get battery draining without wakelocks. I think it's my network since airplane mode has none... Nothing I can do.

Nexus 5 battery problems

Hi. I have a two-months-old Nexus 5 (stock ROM & kernel; rooted). Two days ago my battery suddenly started having some problems. First of all, it doesn't last more than 1-2 hours with normal phone usage. Then it often becomes hot, even when not charging. Last but not least, if I keep using my phone while charging, it charges incredibly slowly, or it doesn't charge at all (the charge remains stable). I'm using the stock charger. Any suggestion?

The Nexus 5 has been proven to last longer then an SGS4 which has a bigger battery, and the HTC one with the same size battery (under proper testing conditions) all while using a faster SoC. Do you troll the forums for those phones as well?
Maybe a Moto G or LG G2 would suit some people better for their increased battery life, but that doesn't mean you need to troll every thread on here with false accusations.
If you'd like any more proof on how the N5 battery lasts longer and is more efficient than competing phones of higher prices, just let me know.

I did what you said; I have attached some screenshots. I'm not an expert about this, but it seems like you were right. What shall I do?

The most important stat to look at is partial wakelocks - it lets you see which app or apps are waking.

Go into device settings > Location. Set Mode to Device only. Ensure that the Google location reporting in that same area is off.
Take another BBS log and post it.

I experience the same issues. Not charging when connected or even lose charge when connected. I am still figuring out what causes it. First of all try using the original cable and charger. Second, disconnect the charger when the screen is on, I read somewhere that can help as well.
Today I had the same issue again, but just before I started charging, the battery would lose 1% per 2 minutes and my phone became very warm.
If I find out more, I will let you know.

That is the problem. That particular wakelock belongs to Google Now. I hope you don't use it, because the solution is to turn it off (from within the program). You could try force stopping and/or wiping it's data. But the fact of the matter is that it's a bug in the app.
Google Now has been this way since it was released. The only conclusion I can draw is that Google doesn't care. It's never behaved properly. And that location reporting (that you've now disabled) is completely out of control, been that way for a year now. I actually greenify the Google apps now. I'm tired of putting up with the lazy programming. Keep, Now, Chrome, Drive, Maps, I greenify all of those. I still allow them to sync, but Greenify will kill them again after they are finished.

I can confirm that I have no battery problems anymore (today after 6 hours of average usage it was still at 80%!!). Thank you all for your help!

Good to hear. If anyone else see's Android OS or Search taking up 50% or more of your battery that can be mitigated.

Take out your Battery, put it on a flat surface say a table. Try to Spin it....if it spins over 2 rounds then you need to buy a new battery.

4.4.2 update and battery life fix

Hi,
I know this subject comes up in a variety of topics and it's really hard to sort the wood from the chaff.
So my "cool story bro" is that I had massively poor battery life following KitKat upgrade and have tried many of those battery saver/greenify apps with no resultant improvement.
I bit the bullet and did a factory reset after I had backed up everything with Kies.
End result is battery life is back to normal today.
Cheers,
Joe

Hello, I've had the Note 3 for just under a week and this battery problem is insanely frustrating. Android System uses more than 30% of the battery. I've tried removing the battery, turning off location, wiping the cache and finally doing a factory reset today to no avail. Android System uses around 36% of the battery and AndroidOS uses 11%. I am on N9005 with Kitkat 4.4.2.

Hi,
I would uninstall all apps you don't desperately need and then do another factory reset. Have you put a lot on it?
Also was the phone new or 2nd hand? Could have a worn out battery in there.

I was going to wait a little before doing another factory reset. On this cycle it went down from 75% to 45% in 3h 20m with Android System using 27% of the battery, Android OS using 11% and the screen using 21% with 1h 49m screen time. Is that right for this phone, or is it discharging too fast?
Thanks.

Depends on what you did with the screen time. Movies would drain it a fair chunk I'd guess. If it's new then surely the Samsung warranty can be used if it does turn out to be the worst case scenario of a bad one (which is very rare so I'd expect we can get this sorted with the help of the community here).

It is normal if u are running android 4.4.2. Android system takes about 20 to 30% of total battery life. You will get similar result although u use the best custom Rom and kernel.

I have fixed the problem to a degree.. right now Android System takes 19% of battery and Android OS takes up 10%. What worked for me was disabling an app called "Universal Daemon(EUR)" and changed keep wifi on during sleep to never. The phone used to always hover at the 300 Mhz cpu frequency and never go into deep sleep, right now it does go into deep sleep. Tho I think I'm really unsatisifed with Touchwiz I guess I'll eventually root my phone and replace it with something that isn't as much of a resource hog.

Worst battery life with 30O ?

Horrible drain for me this night !
I apply exactly the same setting, after my fresh flash. (Disabled GooglePlay Services, Disabled lot of services in Privacy...)
So, clean install, remove uselesswares inside rom, i'm losing 1,3% per hour in idle !
25R was 0.3% 0.4% per hour.
And to compare, i also flashed my LG G3 yesterday, no optimisations, untouched rom, only lost 1% in 10 hours !
Definitly moving back to 25R !
OPO is probably the worst device in battery life i have.

Post battery usage screens. Also, do you use greenify? Custom kernel? Dalvik/ART?
If it's draining that much there must be something running constantly in the background while you're idling and hence affecting the battery life.

Screen was off !
Overnight drain.

There can still run things on your phone, while your screen was off.
That's why he asked

Drain until 1%, then charge.

Well I've been loosing about 1% per hour during the night since I got the phone. During the night I have everything turned off since I only need the alarm.

I'm having the exact same issue as with many others. Definitely a faster drain. Don't seem to be any wakelocks or other things keeping it from zapping the juice. However, it just keeps going down fast...
Lost...

No time to lose, already reverted back to 25R.
Really disappointed of Cyanogen Software.
CM11 is running great on LG G2, Note 3, so why it's so bad on its dedicated device ?!?

I'm not alone ! :good:
We'll probably get more customers feedbacks in the next days, but for me, 30O is a fail.

I just wanted to say that 30O update didn't make battery worse since it was already loosing that much juice already.

I did a similar test to you. Last night, I charged my Nexus 5 and OnePlus One up to 100%. I took them both off the charger at the same time, put them both on Airplane mode and went to sleep.
Woke up this morning, N5 on 99% and OPO on 94%, couldn't see anything notably different looking at the battery stats either... Not sure why it is draining so fast!

Yes, but it only takes you 2 minutes to enter your name, nickname, email and password when registering.

To be honest, the problem is not only with the latest software.
I'm using gummy, which has a CM based kernel and even after disabling everything possible (keep awakes in app ops, all syncs, google play service stuf, app feedback and notification data) and with zero apps in foreground and in airplane mode, I'm still loosing ~1% per hour over night.
The device is in deep sleep and wakelock detector doesn't see any wakelocks besides a couple of minutes of "AudioIn" from google search.
It might be even worse on the latest software, but there is a general problem here.
Either it's a driver/kernel problem, or they're just selling really cheap batteries that get worse over time (unlikely, I hope)... Or it could be the double tap to wake/sleep function(going to test that next night).
On the nexus 5 this option was available when using a custom kernel, but the devs added an option that one could use it, but only when turning the screen off by using the double tap to sleep option.
When turning it off with the hardware button, dt2w would be deactivated.
The reason for that was that the device would always have to wait for and register the dt2w, which could drain the battery.
Anyway, this is the last thing I'm going to try and that I am able to test now, if that's not the problem, it has be one of the other two options.

We know one thing for sure - the idle drain was not there before the update, so it means the update introduced it.
If it's because of the proximity sensor for gestures/doubletap/etc. or some other bug - it's unclear at this point in time.
Most likely it's not related to the radio or mobile phone functions, as people report the same increased drain in airplane mode.

25R is fine for me. 4.4.2.
Nightlies are worst concerning battery drain.
30O has same drain as Nightlies, now 4.4.4
So, what is 30O ? Only M9 or Nightly rebadged ?

That's bad news, I was hoping one of the ways to get back to normal battery drain was installing M9... but seems if OP/Cyanogen don't react to this in a few days, the only solution will be reverting to 25R. It's a good thing I made a TWRP backup

Full 25R TWRP flashable is here !
