It’s called iBetterCharge and all it does is give you a warning– from your Mac– when the iPhone’s battery reaches a certain level. Here’s the problem I run into on my Mac.
My iPhone is in my pocket or backpack. I’m sitting in front of the Mac’s keyboard half the day and occasionally I forget to check my iPhone’s battery level. Then, when I’m ready to head out the door after working on the Mac a few hours, the iPhone’s battery level shows less than 20-percent (or, worse).
iBetterCharge resides in the Mac’s Menubar and gives you a warning– from your Mac– when the iPhone’s battery level has dropped to a warning level.
First, connect your iPhone to your Mac with a USB cable so iBetterCharge can recognize the device. Then, open Preferences in iBetterCharge and adjust settings as needed.
From then on you’ll have an iBetterCharge icon in your Mac’s overcrowded Menubar, and you’ll get a notification when the iPhone’s battery level drops below your specified threshold.
The iBetterCharge developer has a useful video to view, but once you setup the app is just works. Therein lies the only rub I can see. The setup steps, while logical, are not listed in a step-by-step order on the website so you’re forced to guess how it’s done. Just remember to connect your iPhone to your Mac first, then walk through the device setup.
Not bad for free, though.
