Unfortunately, this particular trick might not go down well with social networking fans.
All you have to do is uninstall Facebook’s app from your phone and use your browser to access the mobile Facebook website instead.
The trick has been shown to work on both iPhones and Android phones as well.
Late last year, Facebook was confronted by software experts and technology journalists over its mobile app which appeared to run processes in the background that ate away at valuable battery life.
The tech company acknowledged the problem and issued a fix within a week.
Despite this, it still appears you can save battery by deleting the app altogether. Thankfully you don’t need to remove the standalone Facebook Messenger as well – so chat fans can rest easy.
