I just recently purchased a "new" Moto X from eBay. I've been trying to calibrate the battery, and it seems to be slowly improving, but the results are not what I was hoping for.
Battery drained from 100% to 70% in two hours of use
Charged 100%, left it unplugged overnight. Drained from 100% to 88% by the time I woke up. Could not make it throughout the entire day without having to supplement the charge by around 7:00pm. Minimal use.. maybe 2 hours of screen time, 14 hours on.
Day 3 (today):
Charged overnight. Took it off the charge at 11:00am. Battery remained at 100% until 11:30, and sporadically skipped 99, 98, and 97% and jumped straight down to 96%. It is now 3:04pm, and with light use I'm down to 65% battery. 1hr 40m screen on time, and 3hr 55 min on battery. View the 3 attachments for battery life information.
Is this normal, or is my unit defective?
Edit: I end processes as soon as I'm finished with them, I keep the screen on the bare minimum brightness, and I disabled most of the apps that I don't use.
