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.

Serious drain on watch battery

Bought this after using the original power app.

Must say the features are great being able to add complications etc but like everyone else, it has serous impact on the watch battery.

Average day I used to end with 40-50% battery then I installed power 2 and noticed I was losing around 10% more. No big deal.

However in the last week I've not even got a full day from my watch with it dying around 5-6pm after only being on my wrist since 8am.

I understand there has been a few watch os updates we are to blame as well but removing this app has made a difference. Again watch has been on since 8am and it's currently 5:13pm and my watch battery is 75%.

Hope these issues can be resolved as I really do like this app.

Started out poorly and has gotten worse

Like others, I purchased based on good reviews. It started out "ok" but now simply shows 1% on the watch complication and fails to do anything when tapped. Notifications seems to be sporadic as well: why do I need to know the phone is 83%?

Removing from Watch until issues appear to be sorted.

Very good

I must admit I'm confused about the reviews saying this app drains the battery. My series 2 watch was taken off the charge 11 hours ago and still has 73% battery.
