16 October 2026How to tell if a phone battery is dead or faultyA dead or faulty battery shows itself most clearly through sudden shutdowns, swelling and charge that runs out very fast.

16 October 2026How is a screen replacement priced? What to check in a quoteThe cost of a screen replacement depends on the phone model, the screen technology (OLED or LCD) and the chosen part.

16 October 2026Why does a phone screen lift? What to do if it doesIf your phone screen is lifting at the edge, the most common cause is a swollen battery pushing it from inside.
