My iPhone 5S battery is not doing so well. I've been told after a check that it will probably have to be changed.
In the store I got it checked at they told me the price of changing the battery would be about 120 pounds, but that they often instead of fixing the battery would "swap" the phone for a brand new one, which would then cost about 250 pounds.
After a quick internet search I found that many places offer to change the battery for about 40 pounds.
Is the store I went to just overcharging or are these cheaper places not to be trusted?
