I have an S6, and after installing the latest update push (G920VVRS4CQA3) on 1 February, I've noticed my battery draining like crazy. I mean, I used to be able to go for at least 3 days without a recharge (but always charge it overnight) but now I'm down to 20% charge after just today. I don't do "Social Media", don't watch movies or use it to "Stream" anything, I just use it as a basic phone. I haven't done anything out of the ordinary use... in fact this morning after taking off the charger it only read 95%, that's after charging all night!!!
Obviously there's an issue with this most current update... I am not pleased and would like someone to get back to me about this. Please don't bother with the usual email-chain responses like "... have you restarted, etc?" I'm not that ignorant on these issues, just get a clean update out so I don't have to worry about not being able to use my phone when I need it.
Please address this issue promptly.
