Power 2 is a brand new Apple Watch app that adds a handy iPhone battery life complication to the watch face. The app’s battery complication allows you to monitor the status of the paired iPhone’s battery without pulling it out of your pocket or purse.

While the original Power was based on glances, Power 2 is all about complications. The app also brings a new Time Travel-based battery life prediction function to the table. By enabling Time Travel and moving the Digital Crown, users gain access to an estimate of what iPhone battery life might be in the future.

The Time Travel functionality is a ballpark prediction based on constant iPhone Wi-Fi usage. The app won’t be able to account for activities that put a major drain on the battery, such as watching videos. Nonetheless, it’s a fun general estimate of what your iPhone’s battery life may be several hours down the road.

Just like the original version, Power 2 also features notifications. These notifications will notify you when your iPhone’s battery is running low and when it’s fully charged. Power 2 will only check your iPhone’s battery life once every 30 minutes to conserve energy, and you’ll need to make sure that Background App Refresh is enabled for notifications to work properly.

Due to the way backgrounding and battery management works on iOS and watchOS, Power 2 won’t always lend an exact indication of iPhone battery life, but it should be fairly close. I especially appreciate the complication, which provides a quick way to learn about iPhone battery life with just a raise of the wrist.
