hello,
I have a mi5 64gb and it was running great around one year with mokee rom. some days ago I put my phone out of my pocket and it was dead. there was just a black screen and no reaction. even holding volume up + power for minutes was not working. after around 10 minutes pressing keys together the phone startet into recovery (TWRP 3.2.1) and booting system went normal. some hours later it was again dead...
I thought it's just a defective rom so I wiped everything (system, data, internal storage,...) and flashed a new firmware and a new rom (resurrection remix stable). but exactly the same behavior appears again.
as long the phone is in use, it is working normal. but once it's in deep sleep it seems that it will never wake up.
what can I do to get it working again?
Put it in fastboot mode and try to install Global Stable rom
ok, i'll try that. I'm afraid something is wrong with the cpu because I let it over night in TWRP and nothing happend. but in in TWRP the phone has no deep sleep. would it be possible to increase the cpu deep sleep voltage?
i have flashed the global stable rom via fastboot three times, disassembled the phone and reassembled it but the problem still exists.
when it's in your hand it works great but wearing it in your pocket and after some time it will end with a black screen.
what can i do? is the motherboard defective?
no ideas?
Reconnect the battery from the motherboard
I disassembled and reassemble it but the problem still exists.
maybe sod killer from playstore will help u
I'm having exactly the same issue. Have you found any solution?

Hello,
I have a really strange experience with my G1. Last July when I was trying the latest Hero ROM /I do not remember exactly which/, my phone started to act strangely. When I was playing music through the music player, the phone suddenly shut down itself /without any reason/. I turned it on, the phone booted properly, worked for around 5 minutes and died again. This time it refused to power on /nothing happened when I pushed the power button/. From this moment I told myself that my phone is a complete brick, because I tried everything CAMERA+POWER; HOME+POWER, putted on the charger;USB, there was no reaction at all.
Today I have putted the USB cable /without any reason, hope dies last / and my phone suddenly showed a red LED. I pushed the POWER button and the led turned off, blinked and turned off again, when I released the button the RED LED turned itself on again. I tried HOME+POWER without any result, then CAMERA+POWER and it entered bootloader. Then I downloaded RC29 in order to downgrade it. The phone found the image file properly but it displayed the following error: Battery voltage too low, please change battery, I tried it several times, ending with the same error. I rebooted the phone it showed T-MOBILE G1 screen for about 10 seconds and it died again without showing any signs of life.
What should I do? Can this really be caused from the battery? Or is it something else?
The phone was running DANGER-SPL with the latest radio. I have flashed many roms after the installation of DANGER-SPL. The rom previously installed on the device was CYANOGEN MOD experimental /I do not remember the version/.
Thanks!
I don't mean to be rude, but it says low voltage charge battery. Why not do that, or buy a new battery.
Seems the phone doesn't recognize the full battery, I'm having the same problem - my thread here: http://forum.xda-developers.com/showthread.php?p=5307393
The battery I think must be full when flashing otherwise something goes wrong, but it's not bricked. I'm trying a few things...
I am having a problem with my phone and I'm sure there is a solution for it but I must not be using proper keywords to pull up posts. So I went through the first time flasher's guide and followed it all perfectly, got hardSPL flashed, resynced my phone then flashed the new ROM and it booted fine the first time and I was making a call then my phone turned off, rebooted once and claimed my battery was low which I know it isn't because it was a fully charged battery when I began all this, then it died again and hasn't booted since. I tried plugging it in to my computer's USB port and the charge light does not turn on. If I hold the softkeys and press the reset button or the power button (regardless of it being unplugged and running on battery) it comes up with the screen asking if I wish to restore factory defaults. When I do this it makes no difference in the device booting. When I press the power button the green light will remain solid for a short amount of time then turn off. I don't want to think this is a bad flash because it did work for a bit of time and I was going around and messing with settings and such, is there another possible reason for this and is there a way I can restore my phone to either stock FW or a different CFW?
The CFW I flashed can be found here
Thanks in Advance!
Just sounds like you have a faulty battery to me. Has it got wet somehow lately or leaked slightly?
It was a faulty battery, it had dents in it and I didn't happen to think that the cell inside the battery got damaged, got a new battery in there and its working great now.
So, here's the whole story. My phone's display cracked after it fell. But everything was working normally and the touch response was as good as ever. Being the grade A procrastinator that i am, i used the phone for a few weeks delaying taking it to service. One day the phone charged out. I charged it fully but it wouldn't turn on(but it used to vibrate on pressing the power button like it usually does when switching on). I took out the battery and switched it on again...i did this for about 10 times when it powered on. I continued using it when again one fateful day it charged out overnight (i forgot to charge it when battery was less than 10%). It wouldn't turn on again even after taking out the battery and switching on... for like a 50 times. Then i booted into recovery by pressing vol down and power and then after 10 seconds again pressing vol down then enter(since recovery is the second option in hboot). So, now i'm perplexed..was it the display that's not working?..and then it booted into recovery and the display was perfect. I performed a clean wipe and re-installed the rom that i had been using(Vivokat). The problem persisted. Why is the display working only when the phone is booted into recovery?? Then i decided to unroot the phone and then installed the stock ruu..now as you know the recovery is stock HTC's..i can't boot even into recovery. any suggestions?
hello my friend, recently i got my phone out of my pocket. i realized it was off. i tried to turn it on but nothing, then i pressed the off button on the back and it went on. stayed on for a couple of minutes, then the it frozen, the screen faded and it went off again. i left it the whole following morning charging, when i came back it turned on, stayed on for a couple of minutes (a little bit more of the previous time) then again same thing. if i charges it has a red light (sign that it is charging) if i disconnect the charger and try to switch it on it flashes 3 red light then it stops, and then again three red lights. i tried to charge it via computer but it wont be recognized, i also tried volume up and power button, volume down and power button, and the off button on the back. at the service center they say it cannot be fixed because it is out of warranty since the screen as been replaced by unofficial service. after a bit of charging it turned on today, but soon went off. i need help, i would at least want to know what the issue is. thanks a lot. ps. i can manage to let it work
Maybe try using flashtool to flash software. Don't wipe anything except maybe cache or so. See if that works

i flashed an old backup a few days ago, this backup used to work really well but i have been having this issue since more than a week and it gave me the same problem also with this backup. now i have wiped the chache via cmw. i will wait untill the phone gets to 50 percent of battery, then try to use it without the charger. i'll keep in touch
reply2
i wiped the chache . it worked for a couple of hours, then it went off. now when i try to charge it it shows no signs of life at all. does someone know if this could be a hardware issue? like the battery or something
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.
