iPhone 13 Pro battery draining

[ivanhoe888]

Hi all,

Lately my iPhone's battery seems to be draining very quickly: If it's fully charged at 100% at 8:00 a.m., by 2:00-2:30 pm it's down to 22-23%, sometimes even less. The phone is 3.5 years old.
What would you suggest: Replace the battery, or buy a new phone?

Thanks in advance for your advice.

What’s the battery health? Do you run any app that makes the phone hot or uses much data?

Investigate in the battery settings which app/service causes this heavy battery drain.

The battery health is 85%. The most battery usage by app is Chrome - 29%. I usually keep location services off, because that drains the battery even faster. I know the so-called "rule of thumb" is not to upgrade is not to upgrade unless the health is less than 80%...my previous phone, the XR model, I think I turned in at about 80% after 4 years because I couldn't charge by cable anymore.
