Think your phone battery is failing? Winter could be the real culprit.
As temperatures drop and South Africans pull out jackets and blankets, many people notice another frustrating winter ritual: a phone that seems to lose battery life much faster than usual.
One moment your battery is sitting comfortably at 40%; minutes later it has plunged into the red or, worse, your phone suddenly switches off altogether.
It can feel as though your device has developed a fault overnight, but experts say the culprit is often the cold itself.
Lithium-ion batteries, which power almost every modern smartphone, rely on chemical reactions to produce electricity. Those reactions slow down significantly when temperatures fall, making it harder for the battery to deliver power efficiently.
