I'm experiencing some occasional (every day) boot loops that almost always require a hard reset to get out of. Usually, after a hard reset, my phone will work fine for some period of time. Probably related, I'm experiencing much faster than normal battery drain. I'm used to a full day's worth of battery with this phone, but am experiencing barely enough to last my through a work shift (7am to 4pm). Also, weird spikes of battery loss after a boot loop + hard reset.
I am not sure what is causing this issue. Sometimes, setting my phone down on a table will begin the boot loops, leading me to believe that the battery could be loose or faulty.
As you can see, there is a gap when the phone is boot looping and then a huge loss of battery life. My phone is a T-Mobile USA model that is CF-rooted. I don't know a lot about root, but I'll answer any questions that may come up.
What could be causing this? Any ideas on how to fix it?
Update: My phone battery drains every faster now and cannot even boot to homescreen at all. I am having major problems and cannot use my phone for any function.
Any help at all would be appreciated. I don't want to just take a loss on this device.
I don't know for how long you've been using the phone, but maybe the main problem is from the battery, have you tried using another battery?
and do you get the boot loop problem when your phone is connected to the charger?

Hi!
I have been experiencing strange battery issue for some time now. First, I have to point out that I am using the Nexus HD2 ICS ROM with an early May update. So, the problem is that sometimes the battery drain on standby and when using the phone is huge - 70% for 4 hours on standby, with Wi-Fi and 3G turned off. I guessed it was a faulty battery (there was problem during charging as well - if the battery died completely, when inserting the charger, the phone would constantly reboot before reaching the splash screen), so I decided to buy a second battery to replace the old one. There isn't a charging problem anymore, but the battery drain issue sometimes occurs, which makes my phone awfully unreliable. My question is - is that a problem coming from the ROM, or is it a hardware problem (and in such case - how can I fix it?)? Thank you in advance!
P.S. I am using original HTC batteries and chargers, so it's not form faulty production line

Might be the ROM because recently I've been getting extremely inconsistent and unpredictable battery drain on the same ROM. Sometimes its great and I can last a full day with ease, but at other times it barely lasts me a few hours. I think I need to calibrate my battery though (it seems to run out faster at lower percentages) but that's clearly not your issue.
am having the same problem it suck any fix or ill have to flash whit an other rom using miui ics
The reboot problem is caused by Android's bootloader: it can't charge when the phone is off, so it tries to turn itself on.
I dropped my phone and needed to replace the screen. I have done that and ever since then I have had problems. The screen started responding to touches that I didn't do when it was at low battery. The problem got worse and I wouldn't be able to use the phone unless it was on charge.
I tried to fix the phone by buying a new battery. The same issue starts occurring. It starts from the start tho, so it only does it at low battery now but seems to be getting worse. I have tried factory reset and battery calibration. I am stuck for ideas.
I am on stock ROM 4.2.2 16gb Nexus 4.
If there is any other information you need. I will post it. I also have a log of battery current from "current widget", that I can put up if that would be useful.
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.
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.
Hello
In few days i met with BLOD. I couldn't unbrick my phone until i get my heatgun, and fix it.
Now i have pretty similar problem but dunno how to solve it. Actually i am using PixelExperiece 30.12.2018 and phone sometimes just turn off and can't get up until i heat it up. Its turning off randomly but as i noticed mostly after pluging into charger or pc.
With battery is something strange because when im outside and has left 20% battery phone is turning off and after boot up i see 1-5%, does only changing battery can solve this problem?
Edit:
Tried On StatixOs, AOSP and AOSiP, it still get bricked but as i noticed only when screen is off.
Now im checking when AlwaysOn is enabled, if this wont work, will try with another Custom kernel and at the end on the FullStock
Edit 2:
Better but still shutdowning
