Power 2 enables you to quickly see your iPhone battery life and more from your Apple Watch just by raising your wrist.

Add Power 2's complication to your favourite watch face so you can quickly see your iPhone battery life. Power 2's complication also knows when your phone is in low power mode, charging or fully charged. Its that smart, fast and simple.

Power 2 will notify you when your iPhone battery is running low and/or is fully charged, even if your iPhone is charging in the other room.

Time Travel
Have to run out but forgot to charge your iPhone so now you don't know how long your iPhone battery will last? Time Travel will give you an idea of how long your iPhone battery could last for.


Power 2 is set to automatically check your iPhone battery life once every 30 minutes and will only send you a notification when your iPhone battery is within the following range:

• Full Charge
• 95% – 85%
• 55% – 45%
• 20% – 10%
• 9% – 1%

NOTE: For notifications to work properly, you must have Background App Refresh enabled for Power 2 (Settings -> General -> Background App Refresh).

Time Travel will display estimation on your iPhone battery life based on non-stop usage while on Wi-Fi.

Still broken

Bought this thinking the issues were fixed, but alas they are still here, even at the end of 2017. Battery percentage doesn’t update with the phone. The only time I saw notifications was after I unlocked my phone, which was useless because it was in my hand. This also seems to drain the battery to the point where the watch barely lasts a day. I might give it another try with the latest version of watchOS 4.2 and iOS 11.2 but unless this gets updated, I don’t see the issues going away.

Nice Concept, Poorly executed

It was a nice idea. But like many have already said, the complication isn't accurate & it's draining my Apple Watch's battery way too fast. It's dying 4-5 hours sooner than it would normally, at first I thought it was the beta I'm running, but it was the app. I might reinstall if the battery drain and complication accuracy is resolved. It was a nice try, keep on trying mate.

Great app/complication...huge battery drainer

Really great app and complication. I've been wanting something like this for a while. However, when I had it installed as a complication, my watch battery would die every day at about 7 pm. As soon as I uninstalled the app, my watch would last me all day and would be at about 50% when I went to bed, which is the behavior I was seeing before I installed this app.
