Replaced a couple batteries in a couple iPod touch 6 gens. They turn on and everything works but the battery even after the replacement seems to discharge really fast and I’m not sure as to why. Could be bad batteries ? Not enough solder on the battery contacts ? Any insight would be greatly appreciated .
Bad batteries are always a possibility. Or it could be something in the iPod is drawing excessive current due to a fault. However if you are seeing this on multiple devices, poor quality batteries is the most likely reason. It will be hard to troubleshoot without some known-good, or at least high quality parts. Personally, I like to test my “suspect” batteries with a dummy load so that I can see how much juice they can deliver.
I replaced one today (battery from ifixit) and on first charge it only charges to 67% and don‘t go further. Is this a normal behavior and is a part of calibration?
