Weird battery problems

Mein Problem

After putting down the iphone for a month to do a complete housing and digitizer replacement the battery seemed well working until it would charge sometimes and sometimes it wouldn't i did every test i could and it didn't seem like any battery problem i have heard about so i turned to ifixit and someone told me to try a new battery worked like a charm.

Meine Reparatur

Mein Rat

If having power problems check the battery connector and dock connector then if all else fails try a new battery and don't stress cause ifixedit u can too
