Hello, XDA developers. As you may see, this is my first post, but I would like you to tell me what happened with my cellphone.
Something weird happened with my S Advance after I rooted it and installed CyanogenMod 11. I was playing on it, as I changed MinFree settings and overclocked the processor and wanted to check how the performance increased. Suddenly, the phone abruptly shut off without showing the traditional dialogue box that should appear.
When I took the phone to connect it to my battery pack I waited for like 5 minutes and the battery symbol never appeared; after that I tried to turn it on but it didn't work either. As soon as I arrived home, I connected a proper charger to the S Advance and, still, it didn't respond at all.
About one hour later I took the phone and now, when I tried to turn it on (in normal and recovery mode), it would only vibrate for a few seconds, as if it was actually turning on - with the difference that nothing was happening. The only boot mode that I could enter to was the download mode.
Saddened because I thought it was bricked, I came to my room and plugged it to my computer. The screen instantly showed the battery charging sign, and when I turned it on everything was normal. I used my wall charger to try, and it keeps working fine.
I understand that when a phone battery reaches 0%, and you try plug it to a charger you need to wait like 10 minutes to actually turn it on. But in this case was an hour! And when I finally turned the phone the battery was at 0%.
Could you tell me what happened (for potential future ocasions)?

I have this installed [ROM] CyanogenMod-6.1.0-RC1 for Hero CDMA
I was running wifi tethering and installing a game called chess.
I heard my phone vibrate quickly and the screen was black. I tried to turn it back on. But nothing. So I removed the battery and waited a couple minutes. I cant get it to come on.
So I plugged it into a charger and the red/orange LED is on as if it is charging.
The phone will not even attempt to start up
Any ideas?

Phone just seems dead to me... probably just needs to charge for an hour or so
If it's not charge up and running by now, you'll need a new battery.
Thanksgiving day I had my phone on but was doing things around the house and when I went to check my phone it wouldn't wake. Holding down the power button, nothing, it was dead. I know the battery wasn't drained. So I plugged it into my USB and the light didn't turn on either. I sat staring at the phone for a few seconds to troubleshoot and it suddenly began to boot up and after everything loaded I could confirm it was half charged.
I'm running the same version of Cyanogen as you. Are you using the original battery or 3rd party? Mine is 3rd party.
Have you had other strange occurrences leading up to this? Twice in a week I woke up to find my phone on even though I know I shut it down the night before and not accidentally rebooted.
Since I was able to get my phone to boot back from temporary dead the phone has frozen twice while texting. I didn't battery pull or anything, it just rebooted by itself after a few minutes. I plan on switching back to my old battery to see what happens.
This problem started like 3 weeks ago. I locked my phone and left to do some stuff, and when I came back and unlocked it, the phone thought it was being charged. I plugged it to the charger and unplugged it to see if the problem would stop. It didn't. I plugged it in again and left it there for a few minutes, and when I checked, it was discharging. I pulled out the battery and put it back in after a few minutes and the phone turned on by itself. It is worth mentioning that I'm running Carbon 4.4 from NovaFusion, and you may already know that when the phone is plugged to the charger, it reboots if you power it off. When it turned on, it still thought it was being charged. It discharged after a few minutes, and I left it plugged in to charge while off... And when it turned it back on, the problem stopped. After that, sometimes when I plug it to the charger, it won't detect it, I have to reboot the phone for it to start charging.
A few days ago I turned it off with 85% battery left, and when it turned it back on it showed 0%... And now my phone shuts down without warning randomly. It also freezes and reboots when I plug it to the charger sometimes. I've tried changing the ROM, (to golden-guy's Omni and stock), but those problems persist.
That's why I ask, is it a bad battery o a damaged charging port? Thanks in advance.
Forgot to add, sometimes when it freezes and reboots, it freezes on bootanimation and restarts itself again...
Sounds like a bad battery to me, but wait and see what others will say. It may as well be a faulty usb charging port. If it just had random reboots, I could swear that it's the battery, but with the other stuff you said it seems like something inside the port has gone wrong and thinks it's charging when it's not and the opposite. Sorry, but can't help much as I've never had this exact problem (I've had a similar one) so I'm only guessing right now!

That's normal when the phone has no battery left (or thinks it doesnt't). There just isn't enough power to boot the phone up, but it knows that there's some little power left so it continues to try booting unsuccesfully, resulting in a bootloop If you leave it to reboot for a few mins it might shutdown permanently. That means the battery has absolutely no power left (or it could think it doesn't, when it has, if it's damaged like yours).
S3 mini charging when unplugged
I bought a phone off ebay and was having the same problem. Random usb driver errors with pc and unable to connect with terminal, Startup loops because phone thinks its on charge etc..
Tried everything to sort it out and failed. Just after I was about to give up and bin the phone, I tried to slightly pry the little plate on the USB port upwards with something non conductive. Ding dong I heard to unplug sound animation and the charging icon disappeared
Had no problem since.
Ok so i spend 2 hours looking for a similar problem and potencial tricks to fix it with no aveil..... basically if i turn on my phone without being connected to a charger, the phone will show the samsung logo and shutdown after 2 seconds. Now if i connect it to the charger the phone will start but shutdown as i approach to slide it... then tried getting into recovery mode without the charger and it woul'd just show the blue guy ( clockwork) for 1 second and shutdown... then i tried getting into recovery mode with the charger connected and it worked so i wiped the cache and wiped the data.. so after the formating was done i disconnected it and turned it on and still same problem... so i plug the charger and turn it on again, now iam in the welcome screen and as it get to the setting up of wifi screen, it shuts down but if i stay in the welcome part it will stay on??? and never shutdown unless i finish the set up, after clicking finish the phone will shutdown!!!
- Tried everything, ranging from pulling the battery for 30 minutes to fully charging it.. which i noticed that it wont fully reach to top..
- However the phone does allows me to to get into download mode without the charger being plugged in
- Its a galaxy s3 from tmobile on 4.3 firmware rooted
- All of this happened because i left a game open while it was connected to pc.. it looks like the phone needed more energy than the pc was providing so it drained the battery.. when i woke up it was charging with a thermostat sign ( yes it was very hot)
battery lasted a whole day so i dont think its a dead battery
It should like a duff battery
how to properly recalibrate OnePlus 3t battery to avoid phone switching off at 20-30℅?

Your phone starts to shut off at 20-30%?
yep
sounds like a defective battery.
I've gone from 100-0 a few times and it's never shut down before 0.
Try this after wiping cache only in recovery mode:
After phone turns off, try to turn it on and see if red writing appears, telling you that your phone doesn't have enough battery. After that, charge your phone up to 100% and leave it at that level still connected to the charger, for 10 minutes. Then use up the battery normally. Repeat until phone shuts off at 0%.
This might be a little late for your question, but I just want to share my experience here.
Recently, my phone kept turning itself off at a little below 30%. If I tried to turn it on immediately, it showed the red low battery alert. If I charged it for a few minutes and turned it on, the battery would show 30%+. That proved it had not suddenly dropped to zero and turned itself off, as I understood a defective battery would.
I checked the Net, and it seemed that lots of people have the same problem as mine. On top of the recommendations were to replace the battery and a factory reset.
With the info I gathered, I decided to try battery calibration, and installed this app (https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en).
I restarted the phone three times before running the app (idea from an OP discussion). As instructed by the developer, I let the phone continue charging even when capacity reached 100% (orange container on top). In my first try, I only waited for the orange container below to fill to the max, then started calibration (even when the pop-up message was telling me it's still early). That was a mistake. After that, the phone started dying at a little below 40%. In my next try, I let the charging continue even when the orange container at the bottom showed full, until the app notified me it was ready for calibration. I calibrated, and my phone's battery is fine again.
Hello, lately I've been having some battery drainage issues with my Huawei Ascend P7.
For some reason it drains really quickly (sometimes even when the screen is turned off). Sometimes my battery jumps from 40%+ to 15% and when I plug in the charger, it jumps back to 30%+ really fast.
My phone is rooted, I'm using Doze and Greenify to save some of the battery when the screen is turned off and I also have "Screen power saving" option turned on.
I have taken some screenshots of the battery usage and one of my phone's specifications.
Does someone know what might be wrong with my phone or could there be something wrong with the battery all of a sudden?
Did you try to reinstall Android new?
Or at first a factory reset?

I flashed B852 package's recovery and boot. Then rebooted to recovery mode, wiped data and cache, then rebooted to install mode and installed B852 ROM (dload/UPDATE.APP).
The phone turns on fine, but the battery percentage just drops so quickly and once it even shut off when it was at 60%. When I tried to boot it back up it said it was outta battery.
And one time when my phone turned off and wouldn't turn back on, I plugged in the charger and it told me the phone still had 32% battery. I turned on the phone, unplugged the charger and it shut off in a minute or two. When I plugged the charger back in, it still told me I had 30%+ battery left.
I think the problems began when I flashed https://forum.xda-developers.com/as.../kernel-huawei-ascend-p6s-p7-k-tuned-t3355223 kernel. But I installed a clean B852 ROM and the problem still persists.
Thats really strange, but this kernel is not the problem.
I also have a P7-L10 B852 and using this kernel without any problem...
But right after installing this kernel I also had some strange problems...
Sometime my phone rebooted it self or if it was locked and I pressed the power button to wake it up, it just stayed black and it got really hot...
I don't know what py phone did at this moment because if you are looking at the battery info in settings, it says my phone just was turned off and even lost battery but it wasn't really off...
My solution was a clean install (erasing and flashing every single image and after that 3-button-method)
After that boot up your phone
Now shut it downs install the kernel again
Boot up
Shut downs
(Maybe flash original boot.img
Boot up
Shut down)
Install kernel again
Boot up
I'm using this kernel for more then a half year now and I don't face any problems anymore...
I think the battery itself was the problem. I removed the back cover, removed the battery and cleaned the connector pins with alcohol. When I turned the phone back on about 30 minutes later, under "Power saving" smart power plan option shows me the phone will last for 11 h 30 min at 83% (WiFi turned on), when it used to be like 2-4 hours at 90%. I'll keep monitoring for a while to see if the problem is truly gone.
Thanks for your help.
//edit1: Never mind, I tried playing with the CPU voltages and it froze, so I turned it off. Turned it back on and the problem was back. It jumped down from 80% to 14% and in a minute or two, the battery died. When I booted it into recovery, TWRP says I still have 34% left. So I rebooted into system, it showed me I did have 34% left, but it turned off. Going to try your advice now.
//edit2: Got it to work properly again. Hopefully I won't touch something that will mess it up again.
Maybe your battery itself is the problem but to proof that you will need a second P7 to change batteries of them...
But such extrem battery-problems I have never faced...
You could send it to Huawei support, maybe they will say you if your battery is damaged...
So you could buy a new one and change it
Have you tried calibrating your battery?
I don't think it's a calibration problem
But if you want you could try it...
Charge your phone to 100%
Now delete the batterystats.bin at /data/system
Reboot your phone
Use your phone normally and let it discharge right before it's shutting down it self (3% I think)
Now charge it again to 100%
While charging your phone you should not touch it or unplug the charger
Last night I went to sleep with the battery being at 90%+, woke up to my phone being dead (the alarm didn't go off).
Tried turning it on, it showed me I had 50%+ battery, but it turned off shortly after. I plugged the charger in, and it said I have 58%.
And yes, I have tried calibrating my battery. But I can try doing it again when I get back home from work tonight.
//edit: Battery calibration didn't help. I'll just have to wait until the new battery arrives. Or should I try locking the bootloader?
Why you want locking your bootloader?
Do you want to send it to the support
If you already bought a new battery, wait for it and put it in
Seems that the battery itself was the issue after all. After putting in the new battery, everything seems to be back to normal.
