The above will sort you and display exactly what is eating away at your battery the second may not be the most modern ui but it has a simple enough complication that updates both phone & watch % for nothing,All my Batteries is another gem of an app that highly customisable so you can add beats and other gear like Bluetooth speakers MacBooks iPads etc - literally is all your batteries and none of those require you to unbuckle your pants for a greasy dev to finger what he can out your pockets every 4 weeks! Subs for this type of app are a joke - deleted & wish the App Store had a block feature so you could not see certain devs or better yet switch off all those that now want subscribers for services that most offer free or for a one off small fee! Had to give it a star but it’s not worth that - avoid it!!! The three in the title are the best ones
