Battery draining fast without using the phone
Hi! Two days ago the battery of my iPhone7 started draining fast, without no apparent reason. Battery capacity is at 90%, no apps are open, background app refresh, bluetooth, location services are disabled. The battery continues draining even when the phone is not used and it Airplane mode. It is in Lower Power Mode almost all of the time as well. I have another iPhone with 69% battery capacity, which functions much better. Any help will be greatly appreciated.
