I recently installed Nova Prime on my S6 and am loving it -- except the battery seems to be draining noticeably faster. In GSam Battery Monitor, Nova Launcher shows up as using anywhere from 0.7 - 2.5 % of the battery. While that's not a ridiculous amount, it seems too much for just a launcher. If the screen is off, the Nova battery usage goes down, but when I start using the phone, it seems to rise. Anyone else using Nova and if so what % of your battery is it using?
