S7 after Oreo update Battery - slow and poor battery life.

[BARJAC59]

After getting updated to Oreo a few weeks ago, both S7s in our household are suffering from very poor battery life. Checking battery use it is Android System using 20% and Android OS using 10%. Everything else is 1% or lower. Even with no phone use, the battery drops like a stone.

Also, the phones are very slow - normal use like browsing, switching between apps, opening new apps - it generally feels much slower than before the update.

Barjac59, your phones and service are important to us. Software updates absolutely are not created to reduce that life but rather enhance the services that you are enjoying. As you mentioned that this seemed to happen after the update, do you recall adding any new apps or games around that time? What steps do you take when closing an app? Are you using the original manufacturer charger to charge the phones? Please try the phone in safe mode to see if the battery is still dropping so quickly. See steps at http://spr.ly/6585DUyWd;

Hi and thanks for the reply.

I have installed new apps after the update, I install and uninstall apps almost daily. The new apps show very low battery usage though – Android System and OS are the main culprits. My wife does not install apps on her phone as much as I do, and she is having the same issue – she is actually the one who realised the poor performance first.

When closing apps I generally do a “Close All”. I am using a combination of different chargers depending on where I am, but the one I use the most is the OEM charger.

I will try the safe mode, and then also do a factory reset to clean everything up and see if that helps.

Have you run a health check on the phones to see what apps are draining the batteries?  There can be apps running in the background that you don't know about.  Closing all the apps doesn't really stop all apps from running. 

[BARJAC59]

I use the built-in App Power Monitor found under Device Maintenance, Battery to see what apps are draining the battery. Using this I have placed most of my apps in Sleep mode, but the battery still drains very fast.

Is there another way?

[jrh4054]

You can run a phone health check from the My Verizon app.  That will show which apps are draining the battery.  You can force stop those apps, which will help.  Other than a few preinstalled apps, you can't disable most others.

I have run the health check and it does not show any apps draining the battery. It has picked up a lot of temp data that I have now removed. It is also complaining about my charger – I will test using only the Samsung charger for a couple of days, although I doubt it would make a difference, as I was using the same chargers before the update to Oreo.

[jrh4054]

Good luck!   I think you'll need it.

Before I did the Oreo update I uninstalled every app I put on the phone over the years then cleared the phones cache. Good housekeeping as I didn't use most of those apps anymore. Now I am only installing apps that I really use and so far the Oreo update has been great. Battery life has improved significantly and the fast charging still works fine.  I run the Device Maintenance  every day and its always at 96-99%. You might want to try this before you do a full factory reset as personal settings are not changed.

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.

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?

[ksanger]

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.

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.

[tlb044]

Not sure if something was pushed to my phone after I posted this, but....less than half an hour after my post my phone blew up with more than 50 text messages I was not getting and the battery life returned to normal.

If something was pushed thank you.
