Neep Help: Battery Issue

[randomdude]

See screenshots below. Battery has been like this for a few weeks now. Have tried wiping cache, factory reset, etc to no avail. Can anybody tell me what else I can do? I get 14 hours now but I used to get 36 without any problems.

Did this only start after the Nougat update? We've been seeing a number of posts about decreased battery life after the update.

Didn't immediately notice it after the Nougat update, but I feel like it has been slowly deteriorating since then

5% Cell Standby is not a small amount. Try installing GSam Battery Monitor and show us the graph of the Cell Signal Strength over the course of a battery charge.

I'm seeing similar issues (see post "erratic battery life..." http://forums.androidcentral.com/sa...now-since-upgrading-nougat-2.html#post5808335). Mine started the week before the N update hit my phone. I'll have several days of good performance, and then I'll see the battery tank overnight, like it did last night. A few times this has happened during waking hours, and my phone has always been very hot associated with these drops. Got my phone on 25th November 2016, so not very old to me. Close to having US Cellular order me a refurbished unit, since cache wipe, FDR, SIM change have not resolved the issue.

Just downloaded GSAM, have been using Samsung battery app. Will see what GSAM might indicate as the problem. Usually my big hitter is Android System
