I guess I'm running into the dreaded 70% -> 0% sudden system shutdown issue.
I hear that the issue is power related anyone here know any success with messing around with the CPU governor my device isn't rooted so I might have to go through that process first. but I would like to know if anyone here has had any success with getting their Nexus 10 to hobble along and not suddenly shutdown after 70% battery life.
Are you still on stock rom? I think I have this issue too! OH CRAP..

Hello everyone,
I rooted my phone in early september and put cyanogen 5 on it. I loved the new features but the speed wasn't very good so I switched to biffmod. That's when the problems started to happen. My battery life significantly decreased, I could barely keep it running for 4 hours. When I would open apps like google maps it would turn off instantly, but the phone and text messages worked flawlessly and I loved the speed so I didn't really mind. In the last few weeks it got worse. After a phone call the phone would turn off. I decided to reflash but it stayed the same. Now the phone lasts about 1 minute after unplugging from 100% charge. Anyone knows what could be causing this? or how to fix it?
EDIT : I'm using Biffmod 2.1 with 245 CPU minumum frequency and 556 maximum and DangerSPL.
is this happening on other roms or just biffmod??
Cyanogen 5 was working fine, only hapenned since I switched to Biffmod. (Which is using cyanogen 6)
do a nandroid (plug the phone in for this so it keeps power). then try another rom i say. we can then narrow down whether it is a rom issue or a battery issue. as far as i know no rom should give your battery a lifespan of 1 minute. make sure you have wiped your battery stats too. not sure if this will change anything but you never know.
Looks like a battery wipe fixed the problem. It got past the 1 minute mark! In fact I didn't even know that RA's recovery had that feature. Thanks!
no problem man. i figured it may have been something like that. if the stats dont match then it thinks the battery is low on power when it isnt.
False alarm, it did get better but it shut down after 30min of idle with wifi on.
ok. try a different rom to see if that helps or try draining the battery completely. keep turning your g1 on until it wont turn on any longer. then try charging it from there.
how long have you had the phone by the way?
I got the phone 1 year ago. I'm trying to drain the battery right now. I'll try switching rom after this. Do you have a recomendation? I'm on ebi1 radio.
not sure myself mate. i went for cyanogen, then went to superE as it suited my needs and aint changed since
Hey I was wondering if anyone running any GB ROMs experience huge battery level drops when/if they experience a random reboot or reboot manually (sometimes). My battery will appear to be doing great until the phone is rebooted and then the indicator drops to the bottom...the interesting part is the indicator will always boot to the same level (30%) no matter what level I was at b4 the reboot. I've experience this with both hurricane and stockyish ROMs. I tried resetting battery stats and that ddnt help...

That is a bug in CWM and battery level reporting. You can get your battery level back by either rebooting with a charger on or pull the battery out for 5 minutes and reboot.
Worked! Thanks!
i didnt think that it was a CWM problem... b/c i have noticed that since when i first got my epic on release day..
same thing just happened to me but im still on SFR Froyo so i dont think its a GB Rom, but i did the put the charger in and rebooted.... worked great thanks!
Glad I could help. Didn't realize some people saw this on stock. So it may be a reporting issue or momentary voltage drop. Either way at least we can work around it.

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.
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.
So, i had this random rebooting issue on stock oreo, after installing custom roms it went away for a while but now the issue is back again, My phone will randomly reboot as if my battery has just died(while plugged in or fully charged).. I can be playing games or just scrolling through my home screen and it will reboot without warning, then starts up like nothing happened.. any ideas on how to fix this?

Hey Texas, I'm not sure how old your battery is. But if your battery is on the fritz it could be losing voltage in your phone will shut down. I think you'll normally get a bad battery warning but I'm not positive. I'm using Alpha Oreo 1.3.1 with MK 2000 version 2.2 kernel. And have not had any random reboot problems. On the contrary. It has been extremely stable and I'm getting extremely good battery life especially with greenify. Normally 24 to 27 hours on a full charge. With anywhere from 3 1/2 to 6 hours of screen time.
