The 7 . 0 beta has been absolutely fantastic , very stable even as a RC . The only gripe is that some of the settings have been obfuscated under some unintuitive settings . The battery saver now requires a whole animation to process the changes , which gets old . Otherwise , the performance is brilliant . Even on battery saver , the device is very snappy and responsive . I can ' t wait for the final release ! Edit Also I noticed that Doze works much better and this is without greenify ' s aggressive doze or any other aids . I also was at 3 . 5 hours of SoT yesterday at 50 % but then I had a long phone call and was on Snapchat the rest of the evening , and the latter eats my battery like a mother . I think just having Snapchat open runs the camera at all times , even if you don ' t have the viewfinder open .
