Only time I'm on Wi-Fi is at home or places that have it available. See screen shot below. View attachment 295003
439 apps you have lol maybe somewhere your problem
Now click to add always sleeping then you can add to the list from your apps , dont add important ones because you'll have to click on that app to get notification.
Your going need a little patience with this to figure it out.
I'm not a newbie i've had android devices for many years. So what I have that many apps? I know how to add sleeping apps already. This is a 4000mah battery as I shouldn't have to be going through this after 3 months having this device. I do use a lot of apps but it shouldn't drain and get hot while sitting idle. Samsung support is brutal as I've tried to talk to them, there resort is always hard reset but that just is a band-aid as it can still occur weeks after that to boot.
I'm trying to help you, you obviously tried with tech support and few device and did basic troubleshooting yourself and haven't solved your problem . So all I can do is help you from my knowledge if you want we continue if you don't no problem .
What else do you have in mind to try?
How much storage left on your device?
Fastest way is get rid off all your apps except main 10 apps then see how your battery improves or manual put them sleep until u wake them up
I have a lot left around 80gb of storage. That has no relevance to battery life being affected. You're not making much sense considering majority of apps on my phone I need. Its mostly standby drain thats the issue, it heats up and drains.
OK well aware thanks.One rogue app is all it takes.
It doesn't require two gas gauges.
Forcing and cleaning can have adverse effect if apps needing to do more. They are designed to put a bootstrap in RAM.
3RD party cleaners are nearly always junk.
Security software is notorious for causing battery and performance issues.
At least once, resetting a phone without doing a restore is good to do. Also says, this phone does/does not display problem s xyz. Therefore the hardware is A-ok.
Oreo 8.1 is fine. Even with ATT, Samsung and Google on top.
(I always have a phone for testing such as the S9+ and Pie right now)
Imagine how crappy a phone would run if the rogue app was doing crypto-mining.
The (my) Note never gets warm, let alone hot. Heat kills. A sign of something wrong. Even caused by a software race condition. Bad batteries. Even battery I'll can be cleared up by a reset. Which you've done. As long as you didn't put the same ingredients back into the soup.
No I do not have another device to use. This is my one and only device. How can there be a rogue app if majority of my apps are asleep when not in use??I'm trying to get a better picture of what you have going on with your phone as I'm trying to help through a app and not there with you in person which is harder...
Do you have another device or back up to use ?
You have a lot of apps and it's a strong possibility one of them can be giving you a issue.
You said your getting only 7 to 8 hours total on the battery before charging?

Never seen anybody with as many apps as you have on your phone.
Do you ever go to google activity. And go to my Google activity.
Then click on Today, and change it to forever.
And delete your google activity.
Then delete your google history ?
Still you have a tremendous amount of apps.
