I was just wondering if its ok if my battery is at 57% and I want to charge it back to 100% would that be ok to do?
My understanding is that "conditioning" is more to calibrate the battery meter than to help the battery. Li-Ion batteries don't "like" being totally drained or overcharged. My guess is the phone manufacturers allow the batteries to be charged more than what is optimal and drain lower than what is optimal, but of the two Android phones I've had for ~2 years each I've fully charged them every night and they held up just fine.Yep. There are some considerations if it's a brand new battery, that you may want to completely let it drain a couple of times before fully recharging it. This is known as "conditioning" and there is lots of info on it on the internet.
Personally, I don't bother, but supposedly it's good for it and will let your battery last longer.
