The new update is consuming way too much battery for video playback. Yesterday i lost 12% for just 30mins of playback. When i first bought the phone i used to lose just 7% for a hour of playback back then it was running on 4.3 but now with kitkat prior to the two new updates i was losing 10% for 50mins so samsung is really messing something up bigtime to make us upgrade to a newer phone.
