Combining iPad 3 & 4: need advice
I have an iPad 3 that works just fine but has begged me for retirement :)
I also have an iPad 4 with broken glass that has stopped working properly (at least it can't charge but in other cases has shown no faults so I suppose its logic board is ok and it might need just a connector unit or maybe battery replacement).
So I found that I can simply replace the screen from 3rd to 4th.
And the questions are
- what should I check to locate the flaw that prevents iPad 4 being charged?
- can I replace the battery from 3rd to 4th if it's the problem?
