You can check the battery status of your phone and watch with your watch.
Compatible with complications (automatic update).
You can check the charging amount and charging status of the phone in a timely manner from the clock face.
We will notify you by a notification when the charge amount of the phone or watch becomes less than the specified% or becomes full charge.

- Set up complications with the watch app on your watch or phone.
- The battery status displayed in the complication is automatically updated approximately every 12 to 60 minutes.
 The reason why the update interval has a range is that it depends on Watch OS.
 If the automatic update has stopped (for example, there is no update for more than 1.5 hour), tap the complication to restart it.
 In the iPhone app, the latest update time is displayed under the watch's charge status display.
- Tap the complication to update to the latest status.
- A circular complication can be assigned to the outer circle and the inner number to indicate the battery level of the phone and watch, respectively.

This app is heaven sent!

I think it’s ridiculous that I can’t easily see my iwatch and iPhone battery power (or better yet, ALL of my linked devices like headphones, pen, iPad, remote, etc) on one complication and get alerts when it’s at a certain percentage. This app does it seamlessly. The only reason I give it 4 stars instead of 5 is the automatic update option. I can’t set it for anything other than 30 mins. If I could select the timeframe that works best for me (in my case auto update every 3-5 mins) then this would easily be 5 stars for me ⭐️⭐️⭐️⭐️⭐️. Or if it displayed the battery power of ALL linked devices (Apple or non-Apple) when clicked. That’d 5 star it for me as well.

Beat Apple at something

Ever since I got my Apple Watch I was hoping that I would be able to check my phone battery level without taking out my phone but with the stock apps from Apple, the Apple Watch simply doesn’t do that, but battery phone did. I am a long time user and can recommend it with confidence. However, recently, when both the battery levels on my Apple Watch as well as phone would drop below the percent o would program the app to notify me, the app would not notify me until I actually open it. Can there be an update to fix this issue?

Really good but still has some room to improve,

I really like this, makes it easy to get a rough estimate of my phones battery without having todo anything, which leads me to one of two complaints. The complication should be able to update faster. 10? Maybe 15 minutes instead of 30. And AirPods support would be pretty cool as well. Just have every battery right there when you need it
