Things to check: (1) Are you using the original fast charger? “normal” chargers can take over a day to charge the battery in this phone. If yes, see if it charges another device. (2) It is possible your charging cable has broken, so try charging another phone with your cable. Also maybe try another USB cable on your charger. (3) If it still will not charge, maybe the charge port broke in the phone (you can purchase a new charge board on ebay under $10US). This is common if you had to hold the cable a special way to allow it to charge before, which is a sign that the connector has started breaking internally, and a new charge board will be needed soon. (4) Also it is possible the battery just died. Dead batteries will not charge. The phone will require at least 4% battery charge to even try booting up.

Has anyone tried replacing their ZE551ML battery this year with iFixit’s replacement battery?

Their calibration process suggests draining to less than 10% and then charging to 100%, but my battery never reaches 100% even after days of charging. Original charger and USB cable test fine, and the battery does charge, but it stops charging at some varying percent (usually like 85%). I’ve never seen this on any other battery supplier.

I’ve tried 3 replacements already, all have the same issue. The iFixit battery replacement warranty is amazingly easy and helpful! I’d rather just have a battery like the original that lasted 5 years with no issues.

Any thoughts?
