It's time for that update

I love the simplicity of this app that does exactly what it supposed to. Since it hasn't been updated for almost 2 years I would love to see the Complication added and other features you mention in other reviews and bring it up-to-date to the current iOS.
Otherwise it's perfect!

Hey, I'm working on a new version including a watch complication and many other features. It won't take long anymore – promised.

I get a charge out of this app

Works exactly as promised. I use my iPhone 7+ constantly thru the day and often use a lot of my battery. So I do check often see if maybe I should charge with my extra battery while out, or hit the aux. charger in the car or at home or just by checking know that I will make it till the evening, without having to keep pulling my phone out to check it. Apple should incorporate this into the iWatch battery readout. They could have a point on the screen that you could tap when in the phone battery check mode and it would switch between phone & watch. Maybe this is something that the app developer could do so it could be added to a watch face as a complication. Any way great app and works perfectly with my 7+.

Glad you like it! I'm indeed working on a new version of PhoneBattery, that'll include a complication as well as a couple of other new features. Although, this will take some time but it'll be awesome – promised. :)

Very Helpful!

I use this app more than I thought I would. It helps me to check my phone less often and thus indirectly helps to extend my phones battery. Plus I can check how much my phone has charged without needing to go look at it. Nice.

One small request:
It would be nice if I could see how many bars of service my phone has- in the app. Sometimes I drop calls driving I want to check this app to see if my phone has service. It would also be nice to see my Bluetooth headphone battery % in this app too.
