iPhone battery life

If your iPhone battery struggles to make it through a full day, and you don’t want to add an ugly hump to your device, Guardian tech writer Samuel Gibbs has found that deleting the Facebook app and using Safari instead can boost battery life by up to 15%.

Gibbs spent a week comparing battery usage when using the app against a week using Facebook’s mobile site in Safari, finding that he averaged 15% more remaining battery life at the end of each day. He recruited a bunch of others to repeat the experiment, with similar results reported.

A simple tip means that you don’t even sacrifice much convenience by doing so …

We recognize, of course, that there are a huge number of variables involved in battery-life. Even if your phone usage is reasonably consistent, a single extra phone call or a bit longer spent browsing the web can account for the relatively small differences most are reporting. A poll is not going to amount to a scientific study, but a decent sample size should at least give a reasonable indication as to the scale of any issue …

That’s a different size battery (5.96Wh vs 5.92Wh) than we’d seen in supposed 5s prototypes …
