Battery problem, restarting
Hello,
my iPhone fell on the floor in my kitchen about a day ago (no visible damage) but since then the message, that iPhone can't verify if it has a genuine battery, started popping up. My iPhone has also started restarting even when I am not using it. I have never tried to change the battery. The restarting even makes it impossible to install new iOS. Could anyone help me, please?
Sincerely
