A healthy phone battery should comfortably get you through a normal day. When it starts failing, the signs usually show up gradually — shorter runtime, unexpected shutdowns, or a device that feels warm while charging.
One of the clearest warnings is rapid percentage drops. If your phone falls from 40% to 10% in minutes, or shuts off before hitting zero, the battery's capacity is likely worn out. Swollen batteries are a serious safety issue — stop using the device and bring it in for assessment.
Before replacing the battery, rule out software issues: restart the phone, check for heavy background apps, and try a different charger. If problems persist, a professional test can confirm whether the cell needs replacing.
At Adam's Phone Fix, we replace batteries with quality parts and test charging behaviour before hand-back. Walk in with your device and we'll tell you honestly whether a new battery is the right fix.
