I think galaxy s6 is the best battery I gotten on galaxy since the original galaxy s.
Galaxy S2 had great battery on 2.2 os. The min it received update 4.x is ruined the phone battery. Galaxy S3 had mediocre battery and my original droid razor from motorola had better battery life.

Galaxy S4 was alright at battery. Galaxy s6 even with smaller battery then s5 is doing better in my opinion.
