My iPhone is getting quite old now but still works fine, except the battery life appears to be getting worse. In general I charge over night but by about the middle of the day it drops to around 50%, this is just with light use, checking emails, reading the news etc. If I start to take photos it drops incredibly quick. My current battery is over 2 years old, the original battery was replaced by Apple as it kept failing when the phone was cold. I booked my battery to be replaced on the Apple web site and selected Stormfront, an Apple dealer in the UK. They refused to replace the battery as it had previously been replaced before!!! Has anyone had this before? The iPhone is in mint condition. If I book for a battery replacement at an actual Apple Store I wonder if they will refuse?
