Signs Your Phone Battery Needs Replacing

Is your phone battery not lasting as long as it used to? A degraded battery is one of the most common phone problems — and one of the easiest to fix. Here are 7 signs your phone battery needs replacing in 2026.

1. Battery Drains Unusually Fast

If your phone used to last all day but now dies by noon, your battery capacity has degraded. iPhone batteries are designed to retain 80% capacity after 500 charge cycles. After that, performance declines noticeably.

2. Phone Shuts Down Unexpectedly

If your phone shuts off at 20%, 30%, or even 50% battery, the battery can no longer accurately report its charge level. This is a clear sign replacement is needed.

3. Phone Runs Slowly

Apple and some Android manufacturers throttle processor speed when battery health is low to prevent unexpected shutdowns. If your phone feels sluggish, a new battery can restore full performance.

4. Battery Health Below 80%

On iPhone, go to Settings → Battery → Battery Health. If it's below 80%, Apple recommends replacement. On Android, use a battery health app or check Settings → Device Care.

5. Phone Gets Hot While Charging

Some warmth while charging is normal, but excessive heat indicates a degraded battery that's working harder than it should.

6. Swollen Battery

A swollen battery is a safety hazard. If your phone's back is bulging or the screen is lifting, stop using it immediately and contact us for emergency battery replacement.

7. Phone Takes Forever to Charge

If charging takes much longer than it used to, the battery may be degraded or the charging port may need repair.
