How come standby times aren't ever the same as the 100-90's?

    Taking the phone off the charger fully charged the phone won't drop in standby at all till the morning. But standby even with all the apps closed passed anything under 90% is still goes down pretty fast. Past 50% is most notible. Not touching the phone it's still dropping. Anybody else notice this? Bad battery calibration?

    That's why you should only compare full charges to assess if your battery still performs well. The battery gauge is not that accurate and it won't always behave the same. It's just a rough guide.
