Chosen Solution
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?
You can go to 3utools.com and download a free program to your computer. Then, connect your phone and it will sync to the program and give you your battery health. Click on the link near results to expand a detailed description of your battery. Also, using an auto charger can (and will) eventually effect the U2 (Tristar) IC chip on your logic board and will effect charging circuit. You may experience No Charging at all, Slow charging or Fake charging. I would recommend getting a Power inverter installed in your car…or even one that plugs into your cigarette lighter so you can use a original charger plugged into it to keep your phone charged or find an apple auto charger, not a knock off charger as they will cause this issue too. In short, you may need a new battery, test it… You could have a defective charging port or need micro soldering repair of your Logic board charging IC (Tristar)
