Why my battery iPhone information not working

[iMore Question]

Why my iPhone didn't show the correct battery standby time. The standby time is same with the usage time. Anyone has the same problems?

Welcome to iMore!

A lot of people have reported this issue, so you are not alone. Try a hard reset (this does not delete any data from your phone). Press and hold both the power button and home button at the same time until you see the Apple logo. A lot of times this will help fix something that's misbehaving.

Also, try letting your battery drain down to 1%, then charge it up to 100 %. Then after a while, check it.
