The Facebook app for Android must be of alien origin, since their own designers know full well how bad it is but can’t seem to fix or even improve it. If you must check the social network on your mobile device, you’re better off just using the mobile site or getting a wrapper app. Holly found that his Android’s performance and battery life improved dramatically when the Facebook app was removed from the phone. A group of Redditors subsequently jumped in with tests of their own and reported dramatically improved performance when the app was deleted. For TWZ’s latest trial the writer tried out the Metal app for Android, which is just a wrapper for Facebook’s mobile site. Using a Huawei Nexus 6P for testing, the phone had 20% more battery life over the course of a day. This remained true every day over the course of a week.
