Find Out What Apps Are Draining Your iPhone Battery Life with Carat
There has long been a debate as to whether background apps can drain battery life of iOS devices. Many people argue they don’t (or at least shouldn’t) have any impact on battery, and others are certain that background apps do. Carat is an iOS app brought to us by a team at UC Berkeley that aims to resolve that age old question by monitoring what apps are doing on your iPhone, iPad, or iPod touch and then reporting back to you what apps are eating away at battery life. This is followed up with some recommendations on which apps should be quit, killed, relaunched, and some other helpful tips to improve and conserve battery life.
Although Carat is a genuinely useful app that is worth the free download, you should heed the warning of many App Store reviewers who note that, ironically, Carat itself hogs battery by constantly using Location Services. In other words, you may want to check it’s recommendations and then kill Carat itself. That’ll probably be fixed an update, but it is kind of an amusing bug in an app designed to improve battery life.
If you don’t want to download the app, you can follow these basic tips to get a vague idea of what Carat will suggest: update iOS to the latest version, quit unused apps, upgrade apps to the newest versions, restart apps that handle background tasks. Fair advice all around.
