Highly informative. Would be even better if it could identify apps or features that are using a lot of battery power, but which you don't want to use, and give you the capability to kill these.

Great little app

Update, Sun 8 Dec 2019/ would be good as another reviewer said, to have indicator of what is draining the battery, so you could offload or delete these items.
I have had this app for quite a while and it’s never let me down. I choose silent charge for my phone and you also have a few pick your own colour options for battery icon on the free version. 😎👍🏼

Simple and Sweet

This app does what it says on the tin. It doesn't "magically boost your battery" which, by the way, don't actually boost your battery, they just give the illusion that they do. It just displays how long you have to watch Netflix or listen to music or play Bully for example. Definitely worth a download!
