guys, im having quite a problem with my s2 now.

i posted here before and mentioned that my phone is unable to charge because i think some sand went in the usb port of my phone...i tried cleaning the usb port with tooth brush and it got better.

few months later, everything became good but i think because of this matter, my phone charger is abit faulty now...sometimes it will not be able to charge my phone and my phone goes low battery in the morning.

so what i do is i charge my phone using usb connected to my laptop...i know the charging is slower but i managed to get 100% battery every morning (better than risking using charger but might get 10% battery the next morning).

so here's the problem, this morning i woke up and my battery is at 9%. i borrowed my colleague's charger and found out that the charging rate is REALLY slow, so slow that when i use usb to charge, the battery life is draining faster than the charging (when using usb only). that explains why i got 9% in the morning even though it is charging. it is because the battery power is draining faster than the usb charging.

i go to settings -> battery and found out that this "Android system" is using 37% of the power even though i have turned off everything (date plan, wifi, sound, bluetooth, gps). it remained the same even i restart and on/off the phone.

and my phone is heated up when it is charging.

any idea on how to solve this ?

somehow, that "Android system" dropped down to 28%...the problem now is it still charges slow, phone heated up when charging but when i removed the charger, the phone cooled down again...

is it really necessary install the betterbatterystats ? i found out that i need to pay for this apps..
