iPhone5s - new battery gets empty very quickly
Hello I changed a battery for my iphone5s.
Unfortunately the new battery is draining very quick.
It drains 15% every 5 Minutes, when it's in usage.
So I read about different APNs for batteries, but unfortunately I did not write the APN of the original battery down. So I don't know the old APN.
What do you suggest me to do?
Is this a good question?
