nothing out of the ordinary... straight out of the box, same apps I have on my S5, smart switch over.
usage on waze, google maps, calls, SMS, messengers, whatsapps, online trading, banking, insta, FB, youtubes, banking, news, AOG, the usual boring stuff.. wifi on, bluetooth on, location on, powersafe off, brightness mid level. didn't bother with all the setting tweaks...
occasional gaming (as N7 comes with free games), but thats all about it..
did not install any cleaners as i know those are juice leeches..
I can see u r more "heavy" use than me, mine now totally nt much apps but still can't reach high sot, so sad
