Six Signs Your Phone Battery Needs Replacing

Battery

Lithium batteries lose capacity every cycle. The trouble is that the decline is invisible until the phone starts behaving in ways people mistake for a software problem.

The six symptoms we see most

Shutdowns above 20%, charge levels that jump or drop in chunks, heat while idle, a phone that only stays alive on the cable, charging that takes twice as long as it used to, and any swelling that lifts the screen or back panel.

Swelling is the one that cannot wait. Stop charging the device, keep it out of a pocket or bag, and bring it in — a puffed cell is a safety issue, not a convenience issue.

Software settings that mask the problem

Performance throttling and battery-health limits can hide a weak cell for months. Check the built-in battery health figure: under roughly 80% capacity, a replacement usually restores full-day use.

Before any swap we test charge behavior under load, so you are not paying for a battery when the real fault is a worn charging port or a background app.
