7 Signs Your Phone Needs a Battery Replacement

20 Sept 2026 · By Savji Mobiles

Signs of a worn-out battery

  1. The battery drops very quickly, even when you are not using the phone.
  2. The phone switches off at 20 to 40 percent.
  3. It heats up while charging or in normal use.
  4. Charging takes much longer than before.
  5. The percentage jumps suddenly.
  6. The phone restarts by itself under load.
  7. The back panel or screen lifts, which means the battery is swelling.

A swollen battery is a safety issue

If you see a bulge, stop charging the phone and have the battery replaced at once.
