i have many smatphones and parts for them as im certified technician and i deal with them day by day
ive noticed that galaxy s3 and his clone s3 neo codename s3 neo+
have same damn issues " common Samsung u havent even try fix your shit -_-
basicaly from all samsung and none . s3/s3neo
have powerbank capability issues
or it wont charge
or it say charge but its not
or it charge ok and boom just uplug it self
i found what cause this problem its factory issue caused by wrong cercuit that makes the phone to charge from flowless 5.0v output
not many powerbanks are so perfect ti output 5.0v
mostly it jump from 4.7-5.3 and its bad
if you look for best solution loook for certified one by samsung or some known company
also if you already got power bank and its not charge your device , i bet u trying to charge from 2A output port
better use 1A will not unplug it self
if your powerbank keeps turn it self off it means no power to charge your device
but wait it charge my friends iphone , and china tablet
yes it is but point that chaina is shit and will charge it self even from atomic reactor and explode
iphone is all china
when things come to Voltage things must to be exact for Trade mark devices
beside that if you installed CyanogenMod 12/12.1 and you phone started to drainnyour battery any device
contact me ill drop you fixed kernel
Samsung > Apple
