My phone is updating almost every month.  This last update used up my battery to 7% in less than one day.  I don't understand why a security update should change the battery usage.  Nor why the battery usage monitor moved / changed.  I went to settings to see what was causing the issue.  Found the "New" "Improved" battery monitor under Settings / Device Maintenance / Battery.  The "New" "Improved" battery monitor was turned OFF.  Another terrible update for Android phones.  Why can't they just leave my phone alone.  I don't want to spend another 40 hours tinkering with my phone settings because the great Software Engineers at Android, Samsung, and Verizon gave me a SECURITY UPDATE that IMPROVED MY USER INTERFACE and MESSED UP MY phone.

I did find I now have apps opened up and sleeping that I have not used in ages.  Maybe they use the battery while their sleeping.  How is having all these apps sleeping giving us increased security?  Apps should not be asleep unless we used them.  After which I usually then "CLOSE" them.  Now I have to DISABLE THEM TOO.  A very useful new feature.  Let's turn on all of the customers applications so they start up faster and check for UPDATES he doesn't need.  I swear most of the software updates just take our great apps and enable them to serve us advertisements and download this stuff and use our battery.  What a SCAM.  ANDROID is terrible terrible terrible.  Sick and tired of having to turn all this stuff off.

Please stop UPDATING my phone.  I don't want any new features.  There has been no new features since 2000 that I need.  How Verizon Samsung and Android get away with modifying the phone I actually bought is beyond me.  Suck me in, then Update my software until I'm no longer happy and the original functions are no longer there.  Then try and sell me a new one that works better.

You can delay the update installation, but it has to be done every day.  I did it for over a year with the Nougat update.  My phone hasn't been updated for nearly two years and other than some excessive batter usage, is working fine.  Have you run a health check to see which apps are draining the battery?

When I open Settings / Device Maintenance, it does a scan and wants me to delete unnecessary files.  I don't know what these files are, there is no list, so I do not want to delete them.   There is no option to scan battery usage.

Selecting Settings / Device Maintenance / Battery / Battery Usage, shows I have 8% Cell Standby, 7% Phone Idle, 6% Android, 4% Screen, 4% Android OS, 3% Google Play Services, 1% Voice Calls (10 min), and 1% Messages.  Phone is currently at 50% after 28 Hrs, expecting another 27 Hrs left.   Of course I do not know what killed the phone the other day when I had a problem and it was at 7% with less than 8 Hrs of usage.  I did not notice the Battery Usage button the other day.  Maybe I saw that the App Power Monitor was off and assumed that it meant that I could no longer view app power usage.  After the UPDATE the gui changed and I didn't know the new gui.  I don't want to know the new gui either.  Nor the last three guis.  If I could I would update the developers IDE's and change their IDE's hourly to slow them down.  After all wasting time to create new gui's for my phone is really important.

I have turned off App Power Monitor, which appears to me to put apps to sleep when they are inactive.  But the other day there were apps that were put to sleep that I had not used and should not even have been running.

I've also changed the display settings.  I found that notifications were turned on for the off screen.  This is something that I did not do and the setting must have been made by "Updating" the software.

As for ignoring the update message I was doing that every time I unlocked the phone.  But recently it now forces me to pick a time to update rather than let me continue ignoring it.

Update on the battery issues I had: It is better when I use the Samsung charger - not by much, but I would say I get around 30 minutes more out of my battery when using the Samsung charger. The biggest improvement I was able to get was switching my display screen resolution from FHD to regular HD 1280x720. That has added about another hour to the battery life. I don't mind the lower res, I don't use the phone for movies or games, so it is ok.

I have the same issue, had a corporate team involved and they made me feel as if everything is dandy.  Yet I'm here frustrated, my phone is terrible now. Doesn't charge, takes forever to charge. Battery drains fast, ram seems to be terrible as YouTube and other web pages take several seconds to load. Overall just horrible Verizon wireless experience. I've been with verizon wireless for over 15 years, am ready to try a new service provider. I pay over $125 and can't find it worth paying such a premium with all other carriers catching up on performance. Did your issue get fixed, I doubt it. Verizon only cares about profits it seems. Solution from them is to upgrade to a new phone. So sad, smh

Whatever update we received last week has ruined my battery life.  From full charge to 5% in less than 6 hours.   Searched online for reasons and/or fixes but nothing is working.   The culprit seems to be "Android System" and the phone is warm to the touch.  At one point received a message that too many apps were running in the background and phone needed to reboot.   I have never seen this message, lost battery like this, or felt the phone to be warm to the touch in the 32 months I have owned the phone. 

Please help fix.........and don't tell me to factory reset.

Should also say I don't get text messages unless I open the app.
