so i swapped the battery in my old phone. works great, but when i plug in the battery charger, i get no lightning bolt or charging light. when i unplug the charger the "unplug your charger to conserve electricity" message pops up. the battery by the time has a red question mark on it and the battery widget always reads 90 % and 17h 40m remaining. thoughts? just plug it in every night and see if it dies in a day or so?
