So recently my months old Galaxy S3 is charging extremely slow, say 8 hours from 10+% to 50+% from AC supply using stock charger and battery. I suspected that it is due to faulty charging cable as S3 charger has the USB on top of the charger which physically conflict with AC power points in my house which has little space on top of it to fit the USB.
However, I downloaded "CurrentWidget" which shows that the current receiving from the charger is 999mA which is the same as the specification of 1A which means that my charging cable is probably fine.
The other thing I noticed is that it shows the phone voltage as 3.7+V to 3.8+V most of the time around 30% to 50% battery. Isn't the stock battery 3.7V at full charge or is it 4.2V? Does this mean that the battery is actually fully charged but the phone think that it is only at 50%?
Even worse, it drains battery when I'm just browsing the web even though it is charging. I tried to switch off my phone while charging thinking that some apps are draining the battery strongly but still it is slow.
I have made sure that there are no background apps running with advance task manager and battery doctor apps and it only show "Screen" using 55% of battery in the settings.
A few days and weeks before this problem, my phone hangs frequently and sometimes I had to remove the battery from the back in order to restart the phone. Does this means that the battery or phone is damaged? Or did my phone miscalibrated the battery percentage to the voltage as it thinks the battery is low at a certain voltage because I removed the battery although the battery is still full?
Any help is appreciated thank you.
