So I received the phone today and it had about 40% juice in it at that point. So I immediately got down to installing apps and trying things out on this, and started transferring my music etc, so did not connect the phone to wall charger. Instead I just hooked it up to PC for all the transfers. When I took the phone off the PC usb cable, it had about 57% battery, and then I went about my business around the town in the evening, showing my friends my new iphone-killer When I returned home, it had about 15% battery left, so I hooked it up with PC again after 20 mins of short charging from wall adapter. Now its on 43% and still charging. But a friend of mine put some doubt in my head about the battery life now that I did not charge the battery fully as soon as I got the device. The question I have is that I have the device for 14 hours now, and yes I did not let it charge past 57% so far and have used it heavily ever since. Does that mean I am going to have less than optimal battery life now?? As per my logic, I would immediately dismiss what I heard from my friend, but I am not battery scientist, so still want to ask you battery experienced people. What do you say?
