Pretty good but I miss the speed charging. In addition my battery charges in half the time that the Battery Doctor says so if it takes my phone and hour and a 1/2 to charge Battery Doctor says 3 hours so there's a glitch in your matrix but it works

It worked saving my Galaxy s8 battery! However, the notification cleaner is annoying asking multiple times if an app is providing junk notifications. I turned this feature off because of that.
