iPhone 13 randomly restarts and battery drains to 10%

I have an iPhone 13, these past few days I’ve noticed my phone would randomly restart and sometimes would bring my battery down to 10%! I don’t know if this because my phone is old or something but my battery capacity is 82%

Your battery health is close to the 80% threshold where it is recommended to replace it. Random restarts and a battery charge dropping very quickly are both symptoms of a bad battery. I would recommend replacing it now.

Welcome and thank you for reaching out. 🤗


There appears to be a problem with the internal battery. Only a certified Apple technician can determine the cause and offer a complete solution.


Therefore, I recommend service.
