So when I first got my Note 8 my battery life was great. I would charge it completely before bed then leave it off while I slept. I would only lose about 4 or 5 percent between 6-8 hours. Now all of a sudden it's dropping 25 percent in 6 hours. I have no idea what changed with my phone. Any suggestions or tips?

That's a ridiculous drain if the device is off. Sounds like the battery is on the way out..

[linkiik121]

why are u charging and turning off at night? try charging it all night and see how the battery is throughout the day.

Maybe something is running in the background draining it that wasn't before.

I think he's turning the phone off. So background apps isn't the problem. Unless I misunderstood

Maybe he meant he leaves it off charger while he sleeps. Cause I don't think battery drains while it's off or does it?

[chuck1984]

I take my phone off the charger but I don't turn it off.

This is from last night just sitting on the table next to my bed.

Almost for sure a rouge app. They can be a pain to find on Android sometimes, though. You may have to uninstall a few at a time until you figure out the culprit.

turn off the Bluetooth, wifi , go to the andoird device manager. optimize to 100 percent then go memory and clean it. Hard restart the phone and see if the drain is still there. don't open any apps.

...then go memory and clean it.

This isn't advisable on Android because the system is designed to keep memory filled. Cleaning it will only result in the OS initializing other apps in the background to fill it again. If you use a memory cleaner app like Clean Master, this process will repeat over and over, thus increasing battery drain, not reducing it.

I clean mine everyday before starting the day. My battery is great. The reason I told him to clean the memory is to kill anything pulling the power. He needs to find out if it's a hardware issue or software.

Samsung has been at that game for years.

[chuck1984]

so what are you guys suggesting?

[Mooncatt]

I'm with jejb I thinking it's a rogue app. I'd try rebooting the phone just before bed and see if that corrects anything. You may get lucky and that be all you need.

[b.grdner]

so what are you guys suggesting?

Do you remember the last app you put on it before it started loosing battery so quickly? That's where I would start.

[chuck1984]

Honestly I couldn't even remember what it was

Leave it on the charger. It won't hurt it.

It seems like you have something in the background that is sucking down battery power. When was the last time you rebooted and cleared cache?

[chuck1984]

I restart it once a week but I hadn't cleared the cache.

My battery is still superb since my early October purchase. In fact, all of my phones batteries have been awesome, even my aged note 4.
I keep the minimal amount of apps on my phone to keep me happy and functioning throughout the day. The removal of Facebook and Amazon apps are necessary. I run the two through dedicated browser tabs instead.
Turn off every notification from apps that are not necessary.
Don't run Bluetooth, WiFi, NFC, etc when not needed.
Also, try not to let the battery dip below 40% frequently. Carry a charging pack of possible.

I've had problems with Google Photos. You might check on it's power consumption. It's gone haywire a couple of times on me and constantly runs in the background causing huge battery drains. The problem apparently was an image file(s) on my sdcard that somehow got corrupted for Google Photos. I copied all my images off my phone then started with a clean photos directory on the sdcard. Everything went back to normal.

[chuck1984]

I will have ti look into that

You can see where the battery hog is by Settings>Device Maintenance>Battery>Usage

Charged last night, unplugged and went to sleep and idle until I had to leave the house.
