Hello there :)I have an iphone 4s logic board which overheats. It was intermittent at 1st which let me to believe it was water damaged (corrosion over time).
I scrubbed it with 99% but still it overheats.
The phone is fine when off but when switched on quickly heats up (til overheat pop up) and the battery depletes very quickly.
I have a working 4s shell (my own iphone), and have just hot swapped the boards over so this is, as far as I know, only a board issue. I have a spare battery which is also faultless.

Any suggestions to whats up ? Or what to do next ?
