Charger can’t keep up
I drive for Uber eats. Lately with my phone plugged into my car and the Uber app open and the screen lit at about mid brightness the charger can’t keep up with the battery drain. I have tried the tips for less power usage in ios11 and that helped but it till can’t keep up. A batt app says I’m charging and the battery has about 87% capacity left.
Will a new battery fix this problem? Any other tests?
