My Samsung Galaxy S5 started having battery problems after the Lollipop update. Since many users has reported the same thing I downgraded to KitKat, which included a complete wipe of all apps, but that did not change anything. Maybe the Lollipod upgrade had nothing to do with this?
I did a comparison with my SO's identical phone. I fully charged them, put them in Airplane mode and let them be for 100 minutes. The results? Her phone had 96% left. Mine had 82%. **Four times** as much battery used! Battery monitors report nothing except that the screen and the android system uses most of the battery.
Another unusual thing: normally the phone automatically shuts off at 1% but now it shuts itself off randomly at 2% to as high as 12%. Battery calibration out of order or a dying battery? No, because I switched the battery with my SO's and I still experience the same issues.
I still have warranty left, but we all know that would likely mean I will be without phone for a month so I want to try everything I can first. Does anyone have any suggestions on this issue?

Hi all,
Basically a few days ago I updated the firmware via Kies from 2.2 to 2.2.1 on my Galaxy S. However, I instantly noticed a huge decrease in battery life - 50% gone overnight when in standby! So I factory reset the phone and had everything disabled - the phone only lost 10% in 24 hours. So I decided to try and eliminate the possible causes so first I turned on wifi and within 2 hours I have lost almost 30% of the battery life with no usage so wifi seems to be the culprit
In the wifi menu network notification is off, however, the device seems to be scanning for networks every 5-10 seconds even when connected! I had no problems like this on 2.2 where I could comfortably get 2 days usage with wifi on. Also as I would prefer wifi to be on constantly when connected I would prefer not to change the wifi sleep policy. Any suggestions would be much appreciated
Many thanks, and sorry if there's similar thread already
which version of 2.2 did you have before?
try a flash back and see what happens.
Or try to drain battery (do not charge till 1% or almost dead) then full charge it.
Always happen to me when I flash my phone to a new ROM.
Thanks for the replies. I've tried leaving the battery till it was almost drained but maybe I'll let it go completely flat and charge it see if that makes a difference?
Also trying juice defender from the market to see if that helps. Not sure if it is a problem with the firmware though been looking around and a few people seem to have had the problem with no real solution
Might have to go back to 2.2 but would prefer not to as I've noticed a big decrease in lag on 2.2.1. Also can't remember what version of 2.2 I had I'll see how the battery life goes over the next few days after trying a couple of drain/charging cycles hopefully won't have to downgrade it. Come on 2.3.2
Thanks for the replies so far
Battery Bug is Major issue with all the versions of 2.2.1, Battery life is very bad. Even the Browser is worst in 2.2.1. May be in 2.3 it will get fixed.
I have tested all the new releases of 2.2.1. I found its smooth and fast.

Very very bad idea to let the battery go completly flat, it's the best way to damage it and even lose 20% of his initial capacity. Never go under 10%.
To calibrate it properly, wait 10% turn off the phone, fully charge it, restart. (do it again 3 times).

The battery is calibrated to do this already, the charging circuit will not allow power to the device unless there is a certain amount of charge in the battery. It's there to protect the battery from this exact eventuality.

That's how it's supposed to be in an ideal world.
today i woke up and unplugged my nexus from charging.the battery was 100%
after 20 min,with all turned off,wifi 3g etc,i made a call.after finishing the call message came in my screen..."please charge your device,10% battery"
wow...i said,something is wrong,my eyes are wrong.i turned off,then on again,but battery still was at 10%...
after that i charged again...
anyone had the same problem?here in a forum in greece,2 people had the same problem..i have to say i am rooted and paranoid rom...
So first thing is to figure out is a hardware or software problem. Is your battery prematurely going bad? Or has some sort of software you installed caused this bug.
So if you do a full factory reset, putting stock kernel, and stock android os on it, then you can see if it was software or hardware, i.e. if it happens again it is a hardware problem, and if it doesn't then it probably was a bug with the rom you are using.
There's a small bug in the Nexus 4 that causes it to sometimes read off wrong battery values. Usually a reboot fixes this. So unless the same thing happens again, I would assume it's just an unharmful bug . A tip to see whether it's been actual usage or a bug that "drained" or drained your battery: go into android's battery settings. If the graph is running in a straight line from 100% to 10%, it's likely that it wasn't usage but a bug that simply read the wrong battery values. If it's actual usuage that drained the battery, the graph should show a more fuzzy, not-so-straight line.
Happens sometimes the other way, 10% to 100% in about seconds.
I've been having this strange problem these last few weeks. It happens in different ways.
1. Bellow 25% phone randomly shuts off then when i reboot its 0% battery.
2. Bellow 25% at random % I lose phone signal then the phone starts to lag and capacitive keys don't work then the phone shuts off and when i power it on its at 0%.
3. Phone gets to 15% i plug it in to charge, it doesn't charge but discharges to 0% then shuts off and after that it charges.
If i remove the battery then put it back in after it says 0% it may show 30%/20/15/13/25/30 etc. Sometime it doesn't charge after 87% or 92%. Is it the battery or is something else at fault? Also i can't get more then 2h15m screen time whatever i do and wifi drain is 30% in gsam.
Earlier I had same problemes on my Note 1 and it was because of my battery. Probably your problemes are becuse of your battery too.
Ok I will try a new battery.
I have exactly the same problem!!!!
Like exactly.
However I'd like to add some things:
1. Sometimes the radio signal for mobile starts randomly cutting in and out. It will be full bars, LTE, then nothing, no signal symbol. Then Full bars again, then no signal. In 1 minute revolutions. I am not physically moving during this time.
2. Even at near full battery the phone will get super laggy, stutter, and then finally crash. Once it reboots the battery will be 40% or something. Not super low but lower.
3. The camera seems to have a huge effect as well. I will open the camera, take a picture, and the picture won't save...it will just start to freeze the phone up until I have to pull the battery or it reboots on its own.
I also have a new battery coming in the mail.
However I should note that I am Note 4 910-H using a 910-C variant Custom ROM.
I was worried it was the special Modem I flashed to make the C variant ROM work on my H variant phone that was causing the problem.
Great, but unfortunate to see someone else having this issue too.
Ill post results of the new battery here.
Btw, ive been able to resurrect it from a very low state of charge (3% etc). The only way to do this is to use my fast charger. The fast charger is the only thing that will save it. Even then it takes ages to charge and gets white hot while it does. Its like the fast charger is battling for charge against some unknown force.
Post if you remember when you get your new battery. Hope that fixes it for you.
hi
my note 4 910c become very hot when i use the internet , can i change the modem from lower android like 4.2 to android 6 ? is it work ?
I have exactly the same problem and please if any1 finds any solution just share it here... I tried almost everything but not a new battery.
Battery Calibration By All The Ways, Battery Quick Start via *#0228#, Many Custom ROMs, Many Custom Kernels and Many Stock ROMs and the problem still the same even after I cleanly installed stock 6.0.1 ... Any help please.
Thanks in advance.
New Battery fixed 99% of my problems.
However the phone still randomly freezes and disconnects from cell service.
I think its the modem driver. Freezing might also be due to sd card.
So a few times now my note 4 has crashed (black screen) and turned off. When I turn back on the battery level has massively dropped (30-40% gone) yesterday went from about 40% to 0%. The 40% seemed accurate as using it not too much and usually about that percent at that time of day. Also noticed a few other things, when I connect my note to the pc it takes a while to start and stop charging and isn't being recognised by the pc (or the note isn't detecting it is connected to a pc - only charges)
Any ideas?
Try a different battery?
Are you rooted or custom rom?
Hi, not rooted and stock rom. Had an update yesterday which mentions better battery performance. maybe they fixed something. I'll give it a week. Have also contacted samsung. Not sure if battery is included in the 24 month warranty
I'm running stock 6.01 deodexed and rooted, It's happened to me a couple of time. Either its a samsung bug or the battery is just recalibrating itself. Probably the recalibration
That's good to know but worrying. Its really bad if it happens when I'm out. I think I have a good 10 hours of battery and then bam nothing. If I get anywhere with Samsung I'll post back
Hi,
I have a Note 4 SM-N910C variant that is almost 3 years old.
Starting from 5 months ago the battery level would start dropping fast from 35% to 0% in like 2-3min after which the phone would turn off. If i took out the battery and insert it again, start the phone again it would show around 30% battery level. After a while it would start doing the same fast drops in battery level and so on.
I got a new battery, not OEM and now it doesnst do what i was facing above but it randomly turns off no matter if im doing something with heavy or no load on the device.
The turning off usually happens after the device goes bellow 50% battery level.
How can i test if all the components are ok other than the battery which seems to be faulty in my opinion.
I did order a new original OEM battery but it will take time to get to me.
I want to find out if the rest of the components are functioning without faults so i can decide whether i should get a new phone or not.
Please assist.
New battery
I know its not the same behavior, I have 2 note's. Mine is only a couple of months old while the one from my wife is build in 05/15. Her phone when we just received it would refuse to charge above 96%. Sure the phone would say 100% but as soon as you unplugged the charger it would drop straight to 96%. It did this on 3 different batteries, exactly the same behavior. All these batteries are OEM. When you plug it in it would go rapidly to 100%..
Anyway, I wiped the cache on that phone and since this it charges normally.
Been comparing the battery drain and both phones are using around 6 to 8% per night while on stby with wifi on.
Just try this, it may help you!
Thanks for the replies.
I did try wiping the cache and even did a factory reset.
I rooted the phone 2 days ago to try and recalibrate the battery but i didn't help.
I think the situation isn't degrading cause from today the phone is constantly hot and the cpu is running at around 48 celsius with 7-8% load.
I'll see what happens when the new battery arrives, maybe the phone is heating up cause of this maybe not. It's even eating the battery from 100% to 0 in 2h with no real load on the phone.
Do you guys think a benchmark program will force it to thermal shutdown if this is the issue.
I'm still trying to find out if only the battery is faulty or i have a dying phone.
To me you have 2 problems...a faulty battery and a (new) software problem on your phone.
Constant being warm with a cpu load tells me something on your phone is running all the time consuming your battery and causing your phone to heat up, unless it behaved the same before the factory reset and rooting?
You are rooted so try Wakelock detector for root to see which app (if any) is causing your phone to behave like this.
I will try wakelock to do its thing during the time i sleep. But if that doesnt help ill try a custom rom. Im not gonna factory restore and go back to stock rom. Gonna move away from that and see what happens.
