Mugen Power Battery 3600mAh

Around 1230AM, Wednesday, I still had 1 bar left.

I decided to recharge the battery then because I had to go to bed and I was afraid that I wouldn't have enough battery for tomorrow which will be a long day.

In total, starting at 3PM on Saturday, the new battery lasted for 3days + 9 hours == 81 hours with always on email all the time, facebook, phone calls, sms, voip, bluetooth and etc (normal usage)
