Battery issues iPhone 12 Pro
Ohk since ios 14.2 straight out of the box new, my phone charged to 100%. Then after a few days it charged to 80%. I’m now using ios 14.5 and with Optimised Battery Charging OFF, it only charges to 91%. It’s very cold where i live, and i charge it throughout the night, and yet - 91% is all i get. Battery capacity is 100% which it should be given the phone’s only a month and 2 weeks old. Anyone know why this is happening?
