Carat App Saves Your Battery Life

Amazon moves for biggest ever internet land grab

Tired of running out of battery on your iPhone before you can recharge it? Maybe you forgot to plug it in over night and got to work only to realize that you only have half your battery left. Carat will come to the rescue.

This great app tells you what items are running on your phone that you could shut down to save battery life – and how much you’ll save by doing so. Many apps regularly “ping” your service provider or the Internet to check for status updates and the like. Others simply use processor time occasionally in order to keep themselves “in the loop.”

All of them are using up valuable battery life. When push comes to shove, Carat will make you ask yourself.. “how important is having that app open to me, right now?”

On a list, Carat will show you the apps that are currently running on your phone and how much battery life you could potentially save should you close one or more of them down. For instance, it will list “Skype – expected improvement 1h 15m 42s” to indicate that shutting down Skype will save you over an hour of battery time. Nixing Pandora might get you nearly two hours of battery.

Carat works by simply taking measurements of the battery usage (via device access) for each app running, combines that with averages known from other anonymous Carat users, and makes a guess as to how much battery time will be saved. It’s generally accurate.

Carat also alerts you when an app appears to be malfunctioning – which could indicate either an app problem or something more serious like a viral infection or attempted hack. Most of the time, it’s an app that’s “fallen down and can’t get up” that just needs rebooting. Ever had your phone just randomly suck juice for no reason? That’s probably what it was.

Overall, this is an awesome little app and every iPhone user should have it.
