After a recent push update from Optus, I'm experiencing poor battery life from my S7 with a full charge lasting only 6 hours at best.

Have wiped cache partition through recovery and use greenify to shut down as many background processes as possible. Can't seem to identify an offending app at this stage.
Hi @banistersmind - thanks for reaching out! How long have you had your S7 for? How long ago did you do the software update? If you installed Android 7.0 within the past two days, give it another day or two. Sometimes it can take a couple of days for the battery to settle in. Generally speaking, wiping cache partition & doing a reboot is a quick fix for battery issues after a software update (from personal experience).
I have owned my S7 for 18 months. I've been running Android 7.0 for at least the past six months. I installed an incremental push update from Optus about 2 weeks ago and I've noticed the battery drain ever since.
Interestingly, I received another update notification last night. This was a bigger update (about 300Mb). I installed it and wiped the cache partition immediately after. It's probably too early to say whether this update has resolved my battery drain, however from a full charge this morning, I'm down to 19% after 6 hours of moderate usage.
Hmmm, if the battery is still draining significantly more it might be worth have a chat with Tech Support to see if there's anything they can do in regards to it
Weird, 7.0 optimisation software should slightly increase it. There was a battery app I used to test my old s4 battery and note 4 battery, can't remember what is was called though. Also you should have to use greenify after android 6.0. It already puts unused apps to sleep.
