security update nougat - battery no good now

[rescuejg]

I did a security update (software update) on my S7. Battery life is now beyond horrible.

Less than 4 hours of not much use and I'm now at 17% .

Very frustrating.

You might try rebooting a couple times, it might help after major updates. Also check your battery stats to see what is sucking all the battery.
