While using my iDevices I am always thinking of ways I wish they could be improved either by OS updates or with a third party app that introduces a feature I have been clamoring for. It's amazing that no more than a week before Power for iPhone and Apple Watch was released that I said to myself, "I wish I could add a new complication to my watch that displays the battery life of my iPhone".
Power by Surenix is an iOS app with a complimentary Apple Watch app which allows you to quickly check your iPhone's battery and also receive notifications at preset intervals about the status of your battery.
With Power you can easily see, in real-time, your iPhone battery life with a single tap or swipe on your Apple Watch. Power will notify you on your Apple Watch when your iPhone battery is running low and/or is fully charged, even if it is not in the same room as you. You are also provided with useful information, including indications of when your iPhone is charging or whether it has been fully charged.
Power is set to check your iPhone battery life hourly and will only send you a notification when your iPhone battery is within the following range: 100%, 95%-85%, 55%-45%, 25%-15%, or 0%.
I'm hoping when Watch OS 2.0 is released in the fall that Power will receive an update to support third party complications.
Power is available for $0.99 on the App Store.
