Glad to see your reply;
I've installed now the Fingerprint QuickAction module and in 1 hour is not draining actually nothing, it's a good module to use in this device indeed, but i've big hand and i actually touch always with the wrong finger the fingerprint! so it's not working for me ahahah but that actually don't remove that the module is working very very great!
I've installed Amplifytoo! i've just restrict 3 wavelocks and i don't see any problem (yet) but any battery long live (yet) also i will let you know!
I like Clean Master more than the other app because it actually have kinda different "clean" mode, aswel it works like very other app in the playstore but it can make you choose what IGNORE and what to DELETE, so it's useful for the one that play games and maybe got some cache or save-data to not delete! (it delete apk aswel, some hidden folder too)
About Repair Battery Life and Repair Battery Life Pro my dude, just search on google some reviews about the app.. they all say it's a fake.. hope it won't take some memory of your RAM (not a problem at all) but i don't want you to waste some space! (and aswel i can say that i've test it MYSELF!)
Oh man i want to say more:
Have you never notice that your device can be very hot when quickcharging or when playing very very heavy games or not optimized games?
Well, that don't affect the battery!! Well yes that the battery drains more when you're playing heavy game, but it's not because it's hot.
Why i'm saying this? i've downloaded Cpu-Temp and see that the device is not hot as it seems! it won't come up to 40° (when quickcharging 50° not more) and that's absolutely normal! 20° at normal using and 30° at using a lot, also more than 60° is a problem..
But we are talking about a Li-po battery
Thanks again for your reply!
