Why is my battery life draining so fast?

[AC Question]

It is a Samsung Galaxy S3. It charges all night only to about 96%. Just had a phone repair company even put a new battery in yesterday. Same problem drains very quickly.

Did you set a new but has long lay battery. If she is a few years and she never charged even if it is new, it may not work

Welcome to the forums. It might be an issue with the battery reporting. Have you tried either a cache clear in recovery or a reset?
