iPhone 5 killing batteries.
I have an iPhone 5 that came to me with a battery problem. It was dead when it arrived so I put a brand new battery in which got it working fine.
The next morning it was completely dead again. Nothing when I connect to iTunes either.
So I put another battery in and same story. Works fine then the next morning its dead.
Both batteries are completely dead, I've tried them in a working phone and nothing.
Each battery I tried was from a different vendor, and I also put one of the same batch into a different phone at the same time and its still working with no problems, so I think its safe to say its not the batteries themselves causing this.
I have a feeling its the logic board rather than the lightning port killing the batteries.
Does anyone have any ideas? I don't really want to spend any more money on a new lightning port as I have killed two batteries and I have a feeling its not gonna sort it.
If anyone has a clue, please share.
