Chosen Solution

Hey I have a iPod touch 6th gen come in for repair anyways, this is the third one that came in wasn’t charging or turning on… so I decided to change the battery and re solder a new one in. It’ll charge very quickly and drain fast as well. I’m not sure if it’s the batteries I am getting off eBay or if something hardware is at fault on the logic board causing this issue. Is this a U2 IC Failure? Any shops that have this same problem it would be great if you could chime in with a Solution. It also recognizes with the computer and charges at 0.72 volts

Try the battery that iFixit sells. iPod touch (6th and 7th Gen) Battery iFixit generally has decent quality batteries.

ipods generally have a terrible battery life,
