Battery Doctor

It's quite good. It seems to help. My iPhone needs charging every 18 hrs or so as I have lots of apps and phone numbers and it's never off. There's a function which boosts the memory availability. It seems to be a con.
You start with it denoting 86% or so used up, press boost and the reading swings down to zero then back up to roughly 35%. Very impressive(?). So, if you are like me you then remember to delete all your apps still running in the background. Sometimes I have 10 or 15 which I can easily swipe out. Snag is, when you go back to this app
It now reads 75% ish! Really? It goes back up to twice the memory use AFTER swiping out the background apps?
Don't understand that. Surely the opposite should occur. So, in case it was fault with the app I downloaded two other similar apps and tried them. Same result for both. What's going on please ? Kept this, dumped the others. Hence only two stars.


To be honest,I'm not sure whether an App like this really helps, but I always use it when charging my iPhone 7Plus (and before that my 4S, 5S and 6).
It may be all in the mind, but I do believe it helps a little bit, especially if you observe all their guidance notes in shutting down in-used applications and clearing your Cache and Junk Files.
Every morning I use the quick access on my notification screen to boost my battery, so at least I feel I'm doing the right thing (whether I am or not remains to be seen!)
All in all a nice clean, easy to understand App which I give 8/10

Good to see what's using up battery life..

I like this app & have had previous version for couple years. I'm not to sure on the 'Storage clean up' feature, not really sure what it does or how it helps my phone battery life..
I like the other features tho.. ie, seeing what apps are using the highest % of my battery.. How to optimise my phone & eg, by turning my screen brightness down I could increase battery time by ??? Minutes. I like being able to see how long my phone's going to take to charge also..
