Signs You Need a Battery Replacement
If you're experiencing any of these issues, it may be time for a new battery.
Rapid Battery Drain
Your phone goes from 100% to 0% much faster than it used to, even with normal usage.
Overheating
Device gets unusually hot during regular use or while charging — a sign of a degraded battery.
Swollen Battery
Screen or back panel is pushing outward? This is a swollen battery — stop using the device and bring it in immediately.
Random Shutdowns
Device turns off unexpectedly at 20%, 30%, or even higher — the battery can no longer hold a stable charge.
Slow Charging
Takes much longer than usual to reach full charge, or doesn't reach 100% at all.
Battery Health Below 80%
iPhone shows battery health below 80%, or Android device shows degraded battery in diagnostics.
