What i was meaning was try it switched off just to make sure it goes all the way up to 100%........possible reason its only going to 99% whilst you have it switched on is due to apps etc running in the background etc
It'll be wise to repeat the process one with a quick charger and another time with a regular charger, if possible turn off the phone while charging.
sounds good, keep us updated
keep testing, thanks for the feedback
