Consumer group Which? has found that updating your smartphone’s software to the latest version of operating system may have an adverse effect on battery life and storage. Manufacturers generally urge users to download and upgrade to the latest software when it is available. Indeed, both Apple and Android claim the latest versions of iOS and Nougat improve battery life, rather than hurt it. However, Which?’s research found an iPhone 6 lost 38 minutes of battery life when updated to the latest version of Apple’s iOS software, iOS 10. A Google Nexus 6P also fell from 12 to 9 hours of battery life when updated to Android’s Nougat 7.0.
It’s hard to say whether an update is going to affect your phone or not. The problem is, you cannot revert to the old software once you’ve updated. It is recommended you keep your phone up to date with the latest software but often early versions bring with them a number of bugs. So, we’re urging you to think before you update; if you can hold off a few days, wait and see how the new software has reacted.
