I have a droid x, & two batteries, both standard stock batteries.
Say I deplete one battery to 50%, switch batteries, & use that battery till its low. then recharge to 100% and switch back to battery one. Battery one will tell me 100% almost every time, its charge % is never what it was when I took out the battery and switched to my second battery.
I'm concerned because one I feel I can't charge my battery all the way, two, because I can't charge my battery am I hurting my battery and its life span by not completely charging the battery? Three I never know how much battery I actually have, & four I know these batteries aren't supported to be completely discharged, so if my battery was at 50% and it thinks its at 100% will it over discharge below where its cut off point is and hurt the battery?
