Hey guys
i got SGS2 with Slimrom 4.4.4
When I use the phone, its screen starts flashing brightness up and down after it happens the phone shut down
When I start charging the phone is starting to be loaded from 0% (before it shuts down the battery was 60 percent)
After I load the phone from zero percent to 5 percent at least
I turned it on and he returns to the normal percentage that he had before it shuts down
It is important for you to know: After the phone turns off the first time I can not turn it on without to charge it
All those who think that the problem is the battery: I bought a new battery but It did not help

I found my Atrix totally discharged this morning, you know this situation, it does not start even plugged to AC charger. I switched my sim card into my spare phone. after ~15 min of waiting my Atrix did start and battery stat. showed 0%. at 12% (ater ~30 min) I shut down the phone via menu (long press power button -> shut down) and when big charging battery picture appears on the screen charging status was 60% ! same 60% I found when I boot the phone into OS (CM7). so I'm curious what caused that 50% jump in charging status and I'm not sure now when I'm at 100% is it 100% or just 50% ????????
Flash juggernaut's battery fix and then calibrate the battery to take care of that.

I have a note 1 N7000, and each time the screen began flickering and after that it shut down. This got worse after flashing a cyanogenmod rom. By plugging in the charger the battery seemed empty, but wasn't. After a while the battery indicator used to show charged 70 % or more. Put the charger cable off and the situation repeated after a short time of usage. Last night it started turning off at boot and wouldn't turn on unless on charge. I flashed a original JB rom since the problem doesn't happen when on recovery/download mode. but now it does it even when connected on charge.
HELP

Hey XDA community,
Two days ago, I flashed my S2 to Cyanogenmod 12.1 and as always, the battery dropped to below the 15 %, so I put it to recharge. After some downloading and updating and installing, I put the phone to recharge again while it was on 4%, and I left it all night (for 7 hours) and when I woke up, I found it only at 22 % !!!
I turned it off and went to work on my laptop and put it to recharge on USB cable, the problem is that instead of recharging and going up, it showed that it was recharging but going down from 22 to 19 to 12 !! After some turning on and off and going to recovery mode, the battery died and I left it turned off for recharge, but it stayed on 0% for more than an hour !! It won't budge anymore.
I turned it on and off so it will completely discharge and recharge it with USB cable and an AC USB adapter and it actually started recharging. I took it off at 64%, flashed back to Jellybeans (JellySnap) thinking that the CM 12's battery issue isn't fixed yet, but even on Jellybean, I'm still struggling with the battery problem ! This is what happens now :
_ Recharging while turned on : It would show that it is recharging for 7~15 seconds, then it will ask to connect charger even though it's connected.
_ Recharging while turned off : The loading bar is moving but after 7~10 seconds, it would stop and the phone would either turn on by itself and start the same problem up there OR keep on rebooting on the Empty battery with the loading circle screen.
I also left it to recharge all night (6 hours) and when I woke up this morning, I found it stopped on 20%
I left it to recharge now (turned off), and so far so good, the loading bar hasn't stopped, but I need to know what is the cause of this issue. Is it software/firmware problem ? The battery ? The micro USB port ?
Hello everyone, I'm new here on XDA, so i hope this is in the right place. I have a problem with an old i9100 that i recently got as a gift.
The phone was given to me without battery, so i bought one and immediatly installed Lineage 14.1 nightly (latest build, 13th dec). Then i started to notice that the phone would go off and the battery would drain to 0% unexpectedly. The phone works fine until the battery reaches a level of about 50%. Then the phone suddenly shuts down (sometimes i was able to see the screen flicker right before it happened). So i got the battery replaced, however the simptoms remain.
After regularly checking /sys/class/power_supply/battery/current_voltage i found out that the battery is mostly stable on 3.7-3.9v for an hour and a half until the 60%-50% threshold is passed in the battery indicator on the status bar. Then it rapidly drops the voltage down to 3.4/3.3v in a couple of minutes, where the phone shuts off. I have already tried to clear the cache and reset the battery stats through rootEssentials.
I was unable to find something meaningful in catlog's output. The moment of shutdown is around 22:13 and next boot is 14:19 (i left the phone with the battery off during the night). The log suddenly stops and starts again as if nothing had happened.
is it possible that i got two faulty batteries, is it a software problem or should i be taking it to a repair shop?
Thank you in advance for your help!

Hi
I've noticed slow boots recently after a few hours of phone being off but didn't pay attention.
the phone was working normally(considering age) when booted and restarts were fine.
the other night I turned the phone off over night and now it wont boot.
it turns on and takes a few minutes on Sony logo then a few minutes on Android logo then boot animation comes but struggles to show the animation so takes a minutes to load frame by frame! eventually boot animation starts and stays there for about 40-50 minutes then the phone restart and again Sony logo.
battery wasn't drained cause after 1 hour of booting attempt when I turned it off(using the red button) and plugged it in it had 41% charge left.
I let it charge to 100% pulled out SIM and microSD but it's the same.
ROM, bootloader ,root...never been touched.
the battery also never been changed! it's 10 years old but never acted funny like sudden drops from 50% to 20% or sudden 80% to 100% when charging.
is it the battery? does booting require more power?! did the weak battery damage circuits?
any ideas?
Thanks.
