I've been using the phone for two weeks now and the battery drain has gotten pretty horrible the past week. I charge the phone up to 100% and leave it off the charger as I go to sleep from 1am - 9am.

I wake up and my phone has 70% battery left with wifi/data off. [Battery drain](https://i.imgur.com/VkAcAqd.jpg) [Google battery drain](https://i.imgur.com/qjxMkN2.jpg)

Does anyone know what I can do? Is there an app with which I can check on what's draining my battery?

Check what apps are draining the battery

You can check which apps is draining the battery.
Just go Setting, then search for "Device Care", then hit "Battery" -> Battery Usage :)

All S10 phones have a bug that is causing them to not deep sleep when screen is off, causing poor standby performance. This is caused everytime you receive a VoiP call, so after you receive one, just restart the phone. Being caused a proximity sensor bug.

Try to wipe disable Google app and check battery consumption. If problem persists, try to wipe cache from recovery and if necessary do a factory reset, 30% battery drain in a night without network connections is not normal. If all attempts fail better go to Samsung assistance to change the battery

7hrs: 10% when sleep, wifi on. Not good but I think it is not too abnormal. I think, samsung still have a lot of bloatware!
But on screen I thnik is OK: 5-6h mixing, 3000mA battery on a strong SOC, it's normal. My back up Huawei GR5 2017, 3400mA, it is the same time!

This solution was posted on the S10 forum and certainly helped me.

There's a bug that stops the phone from going into a deep sleep mode post making a call (audio/video) on apps like WhatsApp, Skype et al. The solution for the time being is to reboot the phone once before going to bed. I tried a lot of other things but had a ~2% hourly standby drain which reduced to <5% overnight after figuring out this solution. I have both WiFi and Bluetooth on at night.

You may try to play around with the battery saving tweaks in ONE UI but nothing worked as well as this has. Hopefully there'll be a more practical fix to this soon.

Cheers!

I tried to debug battery drain using Battery Historian. I noticed that the phone does go to Doze mode completely, but for some reason, CPU stays awake. I'm still new to the tool, will try to find out more about why CPU is kept awake all the time.
I get battery drain regardless I make any VoIP call.

Another issue I noticed is PUBG lags horribly on the phone. I tried different combinations of graphics settings, the game was still lagging.

Just tried pubg...hdr +ultra runs ok for me. No lags, maybe sometime stutters for a sec.

Putting the phone on battery saver mode barely drains any juice (Medium Power Saving mode), seems like it's just a software issue and not hardware specific issue.
By the time Samsung releases any fix, we might have to live with this one.

Since the update this last day or so, my battery is lasting way better than previously.

What update? Can you share the info that came with it? My SM-G970U1 is still on Feb. 1, 2019 patch. Although I don't have any problems with battery drain, pulled out two screenshots lately, both over about 12hrs period, one was with cellular radios on and the other just an airplane mode:

Got the March update. Exynos version. Battery drain seems a bit better at first glance. But it's not been long since the update. So not completely sure.

My Snapdragon S10e never gets less than 4 hours of SoT under the heaviest use (I am constantly messing with settings, installing\closing\uninstalling apps, etc etc)

If I use it "regularly" just browsing Reddit and such, with a normal phone signal, I get 6 to 9 hours every time.

I don't use dark mode until Sunset.

I leave NFC/Bluetooth/Location on at all times.

    Ok so, after a few days trying different stuff here's my temporary solution:

    I was getting 3.5% per hour drain with screen off. Deep sleep of only 25% percent of the time. I disabled AOD, Double Tap to Wake and Lift to Wake. Now my phone sleeps like a baby. 0.5% per hour drain. I will enable each one of those one at a time, and see what happens.

    Hi there :)
    Can i ask you from which site did you buy It from ?

    Samsung's.

    I have a discount through my company e-mail of 7% (you can get a .edu student email through some website and get the same discount).

    I also traded in my Galaxy Note8 for $550 maximum value at the time.
