1st gen ipad have charging symbol but percentage not rising
Hi , i have a 1st gen ipad which does not seem to be charging , i got some charge back into the battery ( about 30 %) using a bench psu , so i'm assuming battery is ok
I have been checking voltages around the board , ( ive included the schematic , page 17 , i couldnt save 1 page for some reason )
i have 4.2 volts at L1900 & L1950 .
Which line should be charger voltage back to the battery ?
Is this a good question?

what do you use the iPad for ?

if you are use the device and charging it at the same time you are damaging the battery. so if you re doing that you may need a new battery, but depending on what you use it for I would just get a new iPad. Because it is out dated , newer ones have better cameras, etc.

@needwifi2021 that is completely false. It just charges the battery slower.

I got hold of another battery and that seems to have fixed it ! ..
The old battery took charge from my bench ps though and is still showing a steady 3.8 v now ..
I guess just because a battery can take and hold charge it doesnt mean its ok .
