This few days i encounter problem as batt drop from 100% to 70% in just afew minutes.. then charging rate is super slow.. yesterday i charge my phone from no batt and the phone turn off from 10pm until 9am only 45% charged.. then i check the batt status under setting and it detect the ac charger as usb.. and then i notice got some process i dont know what called GPSD take up until 38%.. searching through google up to no avail.. some said under setting > security > enter ur detail then slide it off.. wth.. some said it was the android remote control setting.. so i figure out that the process is the remote control service.. i enter my samsung acc password and turn it off.. and my batt usage back to normal and the gpsd process dissapear.. about the slow charging i dont know if its a bug or not.. u can check it through batt status menu if it detect as usb or ac.. if it detect ur ac charger as usb, unplug ur charger and replug again until it say charging (ac)..

Phew.. rarely post this long but i hope u guys find this useful.. never happen to me on ics.. now im on jb malaysia stock no root..

Check under batt status if ur phone detect the charger as usb charge or not.. if it is, unplug and replug it until it say charging (ac)

Bb charger quite slow compared to original charger as the output is around 600mAh or 700mAh compared to original charge 1000mAh

Seem that this few days got alot of ppl have charging problem.. and i tot only me.. had this prob the other day also.. im on charging now.. see if the problem still persist im gonna go and change the charger.. my initial diagnosis is the system detect the ac charger as usb charge.. unplug and replug the charger seem to solve the problem..

i turn off the gps, restart phone, turn off phone and turn back on gpsd is still there and take a lot of juice.. i just turn off the remote control service and a few minutes later its gone.. maybe diff setting but that works for me now..

This morning i woke up got like this.. i was charging on usb mode.. 0 - 45% from 10pm to 9am

I turn off google now after there are reporting about jb draining batt via google now services.. gpsd still there.. only dissappear when i turn off the remote control that keep track where ur phone is and the prob dissapear.. might be different thing also.. i dont know.. but for now turning off the remote control work for me though..
