Bad battery life? Your phone’s software updates may be to blame

Unsuspecting mobile phone owners may be left with flat batteries after they update their handsets, despite technology companies promising longer life and better performance from the new software.

The consumer group Which? found that when iPhones or Android phones are updated to the latest version of their operating systems, their battery life can fall by as much as three hours.

A two-year-old iPhone 6 lost 38 minutes of battery life when it was updated to the latest version of Apple’s iOS software, iOS 10. A Google Nexus 6P phone went from 12 to nine hours of battery life when the most recent version of Android was installed.
