Your Phone Gets Unusually Hot
Some warmth during heavy use is normal. Consistent heat — especially while simply browsing or making calls — points to a battery that’s working much harder than it should, generating excess heat as efficiency falls.
The Battery Percentage Jumps Erratically
Seeing your charge drop from 60% to 15% in two minutes, or jump back up when you plug in, is a classic sign of a failing battery sensor or degraded cell. The readings are no longer accurate because the battery can’t hold a consistent charge.
