My mi 5 was rooted and was installed with aosp rom. I downloaded a battery calibration app, where it was instructed to start calibration and then when the phone switches off it should be charged to a 100 percent. I had unplugged my phone at 97 percent, but I couldn't switch it back on. There were no leds or anything. I also tried to charge it but now it wouldn't show anything . How can I fix it?

Running cm7 nightly 53.
I just went to reboot the phone while the hdmi was plugged in. Screen turned off, now the whole phone won't power back on. I've pulled the battery, it won't turn on at all. It's like it just died?
Does anyone have any ideas? It's only a week old so I'm guessing cm7 has bugged?
is ur battery empty? if so, and can't boot, usually remove battery, wait a few minutes, plug in everything again, but don't switch on. after that everythig is normal.
Thanks, it was the battery. I plugged the charger in and the phone turned on. I didn't even think the battery would be dead seeing as I just saw it was at 80% when I hit reboot....
Anyway, now my battery is only lasting 3-4 hours. Before I was getting 2-3 days use out of it without charging. Now I can't leave the house without my charger. Kind of defeats the purpose of it being a mobile phone.....
Sometimes I will charge it, unplug it then unlock it, and the phone will just turn off, as it turns off I can see the battery is drained in the top right corner.
I'm going to try a stock rom again.
Hi all, i have a bug on my phone's battery. today i installed a Rom (Evervol RunnyCM) beacouse i think it can fix my problem. I Always used RUU realeased by HTC , but when i installed ICS from "System Update" on Settings menu, i have a bug on battery. I charge my phone all the night, and on morning i have green led, so i think my phone i charged. when i leave him from charge, after 2 minutes, it turns off, and when i restart my phone, i have 50% battery. Sometimes, when i get in charge my phone and i have around 10-20%, after 2 minutes of charge, i have 100% battery charged and green led. when i leave him from charge, it turns off, and i have about 5-10% of power remaing. What the f*** happens on my phone?

i have this bug, too !!!
Please help
This battery bug is a known problem for quite some time, it can have different behaviours from user to user but basically, when you restart your phone you lose around 10% of battery, but the battery power is still there, for example you can charge it to 100%, restart it a couple of time and feel the real power of 50% battery for 1 day
Me and anders tried to repair this but with not too much success, i could say the simptoms were aleviated but that's pretty much it, the battery driver seems to me to have been developed in an internship, has lot's of TODO and FIXME in the sources.
Hope this helps
so, i can't fix this? i go to buy a new battery...
So I was able flash this Rom http://forum.xda-developers.com/showthread.php?t=2398003 with out any hitches. As soon as the power level goes down to 15% I plugged in the charger while Tab is turned on. It does not indicate that it is charging. So, I turned it off while plugged in. the battery logo comes up and says that it's at 100%.
I turned it back on, now it says it's at 12%, I turned it off and left the charger plugged in for about 5hrs. When I checked the screen the battery logo says it's at 100%. when I turned it on it was at 100% but was depleting the battery fast. I turned it back off, now the battery logo says it's charging. I left it for 30mins. and turned it back on. it's at 8% and cycles from "connect charger" to "charging". Now the tab is dead, it wont turn on. It doesn't even have enough juice for me to restore my back up.
Please, can anyone tell me how I can fix this. I would really appreciate it.

I was using this ROM for a long time and I flashed it over and over without facing any battery problems
so I would say that flashing that ROM caused a battery calibration problem, but sense you can't even charge when your tab is turned off
so I don't think this is the problem
the only thing I can think off is that you should try another charger [I read: cycles from "connect charger" to "charging"]
and yes this might happened, and if you don't have another charger, connect it to your computer for around 5 hours, that would do it
I am currently connecting my tab to the wall, waiting for it to get to 4hrs. I saw this http://forum.xda-developers.com/showthread.php?t=1861229 and am following it right now I hope this works. If it still does not work, I have another charger for the exact same model I could use.
Hi, I was using my XZ yesterday flawlessly and then out of no where it just turned off. I did everything I could find on the forums but it just sits there with the red Led permanently on. I left it charge overnight, when I woke up the led was green and the screen said it had a full charge. I turn it on, it gets to the lock screen and then shuts down again. It's sitting there again with the red led on as if the battery was drained completely in 1 min! What can I do about it? THANKS!

Hmm... Try doing this:
Get it charged till you get the led green, KEEP charging, and then turn it on. See if you can use it for 5 mins, 10 mins, even an hour. See if it turns off automatically. If it works fine while plugged, then that shouldn't be the problem of your ROM. Then, unplug the charger, and see if it shuts down soon. If it does, we can make sure it's the problem of your battery.

I'm gonna check that out thank you! .. and I'm pretty sure it's a ROM problem because it was fully charged and yet it shut down never to be woken up again til 5 min ago that I connected it to the PC and it briefly showed me the charging screen (battery completely drained) and then the Red Led came back on and the screen went away as soon as I disconnected it from the PC. I connected it to the wall charger but the screen didn't come on again. Thoughts about this? (also the computer briefly recognized the phone and then it didn't anymore) right now is plugged to the wall charger to see if the battery picks up, so I can proceed with all the flashing stuff.
What causes this type of problems? I really had high hopes with this phone, it's gorgeous to look at (the best design on a phone IMO) but it failed me
Hi all,
2 days ago I decided to calibrate battery, which is done by fully charging phone, then fully discharging phone with normal use. But phone turns off at 1% and doesn't fully discharge, so I turned it back on and stayed alive for 40mins at highest brightness watching videos on Facebook until finally turned off.
Then fully charge your phone while device is off, (but because device fully drained will be a bit tricky to charge it, don't know why, look like keeps 1% of charge to save charging settings or something) anyway, after a few attempts of plug in and un plug I managed to get it charging, and charged in full.
Result:
Better battery life, obviously. And the strange one is that refresh rate drop when unlocking device as stopped and device is smooth everytime, been over 2 days now without a single drop. Not sure how is this related but this happened with me, free to try it if you wish.
Thought to share my experience.
Happy to answer questions
How did you turned on? After i get the notification that in 30 seconds phone will shutdown, it does shutdown and when i keep pressed the power button its powering, showing mi logo then one logo with empty battery and shuts down again.
