A new app called Normal might help you finally get to the bottom of your iPhone’s disappointing battery life. Unlike any other iPhone battery tracking app, Normal uses crowdsourced data from everyone using the app to provide personal advice on how to improve your battery. Once installed, Normal starts giving actionable suggestions like ‘kill Google to save 1 hour of battery life’ rather than just presenting you with stats.
Somewhere, somehow, maybe less than a year after I got the latest version of my iPhone, its battery would mysteriously deplete in about half a day. I wasn’t really sure why. But now I can find out. There’s a new app called ‘Normal’ out from a pair of Stanford Ph.Ds in computer science named Adam Oliner and Jacob Leverich, who are turning some postdoctoral research into a company called Kuro Labs. Their first project, Normal, is a battery diagnosis service that tracks and compares your app usage to other iOS device owners to see if there are any specific actions you can take to save battery life. The 99 cent app compares your phone’s battery usage over time with other people who have similar combinations of apps.
