My battery will not charge
Have you tried a different charger?
We had old Motorola flip phones that looked like they had the same charger size, however the car and electric adapters did not work correctly for charging our Moto X phones. The car one didn’t work at all, the electrical outlet one charged VERY slowly.
Also make sure if it is a multi part cable charging block all the connections are tight. If you just got a case, does the case interfere with it seating completely?
As a by the by, one of the universal power packs only worked the first few times we used it, now it doesn’t recharge it it only holds the same battery level when we use it, doesn’t charge it, but you can use it for hours while plugged in
