Screen using power when turned off - Samsung Galaxy S9 Questions & Answers

I've got all gestures and everything else I can think of off, I even disabled "Prevent accidental touches" yet it's still draining the battery fairly considerably
Any ideas?

If your phone is rooted, check your deep sleep time in a kernel manager like mtweaks or ex. If it doesn't go into deep sleep, there's probably a app preventing it. You can probably find it under the battery usage in your settings. If you can't find it try DS battery saver, if that resolves your issue, it's probably an app keeping your phone awake. It also could be the AoD thats keeping it awake, I only know about this problem in custom roms, and I don't encounter it on my phone on OneUI, but this could be an issue aswell.

Do you have an SD Card in your Galaxy?
When you have one, than take it out.

Not rooted unfortunately, shame they limited access to app usage, I mean even Android battery status has more info
Deep sleep seeems to work, battery drain in the morning is fine, this is through the day

Bit of an update for anyone wanting to see actual app stats, "Accubatttery" still works fine

Phone waking up a lot overnight. How do I track down the culprit?

My phone is waking up quite a bit overnight while I'm sleeping. How do I find out what app or process is waking the phone up and keeping it awake?
In the attached screen shot, the phone was sitting, screen off, for about 8 or more hours but as you can see there are non trivial stretches of awake time.

}
For reference, I have gmail, google calendar, and google contacts set to sync; was signed into google talk; have an exchange server set to sync email and calendar once an hour; and beautiful widgets set to sync weather once an hour. All that said, those stretches if awake time seem longer than it would take to pull email or weather. Maybe I'm wrong on that though?
Thanks in advance for any help.
If you really, really want to be systematic about tracking down what is draining your battery or keeping the phone awake then I would go back to nearly an out-of-the-box state. Uninstall all your apps (if you're really hardcore then do a factory reset). See how it handles overnight unplugged in that pristine state. Then install your essential stuff that you listed in your post - exchange, gmail, calendar and see how that goes during night two. Night by night add just a few apps and watch for changes. That is just about the only way to definitively track down what configuration or app or combination of apps is causing you problems.

Seconded. Once running, that app will show a detailed list of what apps are causing wakelocks, and from there you can try to eliminate the one that's misbehaving.
I had a same "problem" tryed of course BetterBatteryStats but all the wake at night was caused by cernel proceses kworker/u:0...4 i have no idea what cause it. But recentley i installed Imoseyon's kernel 10 exp1 and now i have no such wake up's.
Hop it will help You, of course if there no real app causing troubles.

That's not normal. Whatever wakelock is keeping it awake is not captured in your WLD screenshot. Track it down in better battery stats instead, using "partial wakelocks"
Thank you...that's what I thought... I don't know what happened...so I went into partial wakelocks and everything looks like low %... But kernel wakelocks there was a lot of high percentages...
First thing that sticks out is drop box. It shouldnt be running for that long. Did you turn on auto backup? This will cause huge drains. If turned on turn it off. Also check in service running for 21 minutes... Turn off your gps. This is Google now constantly running and locating you to try and provide you with what it thinks is useful cards (weather, traffic, food in your area) I only then on my gps when I'm gonna use navigation. Otherwise all apps with gps access will start to run and kill your battery. Also I suggest greenify. It'll help a lot with things like Facebook, Twitter, Google search, ect. Wakelocks. Also removing or freezing bloatware helps tremendously with battery drain. And last carrier iq. Something that always runs in the background. Google search it or read up in the battery threads here on XDA. They talk about it a lot and how to try and stop it. Also this thread
http://forum.xda-developers.com/showthread.php?t=2816353
although for the SGS5 it can be applied to our device as well

also your font looks distorted, i would return the phone! ?

Phone jumping from 50% to 5%. How do I fix this?

Starting last week, my phone would have this strange issue where it would suddenly restart and be at a low battery life. At first I thought it was the rom (Euphoria) so I decided to switch to cloudyg3 to check. Its still happening on this rom too, so I downloaded battery calibration to see if that would fix it and im still having the same issue. Could my battery be causing this? That seems like a really strange thing for a battery alone to do....

Calibrate the battery. I know you attempted this, but you shouldn't restart your phone during calibration. Charge to 100% and use that module to delete the old stats. Use the phone and leave it on until it turns off from no power. There is another module that can turn off the auto-shutoff. Use this (doesn't work on some ROMs) to ensure that you drain it to 0%.

So I brought my device badk to firmware after a lot of abusing of my device......but then,this happened (i changed to a different rom to stop the same battery problem but it wasnt any good) its not wakelock, like when the device is locked, no battery is wasted but when the screen is turned on and i do light activities like google translate, youtube, it drains SUPER FAST! Like for watching a 10 min video on youtube, it took away 3% of battery! I have also enabled power saving, have kind of a decent brightness and the wifi sleep thingybis set to never keep on. So I really need help with that.

I checked and it says I use 2.4.....
Hmm, i guess you have checket others battery drain apps etc, i dont use facebook and messenger on mine..
You can try a full reset on it sometimes that helps. (Iknow it sucks to set it up again)

No nothing like that....
And plus I just flashed it back to stock a few days ago and did a factory reset then.....
Ok, you could try root it again and try find the best battery calibration tools around, then im out of suggestions for now

Massive wakelock from multiple apps (*alarm*)

Hey there, I wanted to show a new kind of battery drain that is happening to my 5X since two weeks every now and then (about 3 or 4 days).
(Nexus 5X with the latest PureNexus 6.0.1 on ElementalX kernel with HawkTail settings)
Apparently at some point, applications like Play Services, MoneyLover, Whatsapp, Tasker, App Google, Weather Timeline, Office Suite, Phone, Google Opnion Rewards, Zooper Widget start keeping alive the device with wakelocks called *alarm* or wake:[service for sync of the app] draining in an insane manner the battery (the first processor of the LITTLE chip is always at max speed).
The really odd thing is this Bluetooth graph in BetterBatteryStats:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Apparently, even if it's off, the bluetooth keep switching on and off. But the thing is that in every wakelock app I cannot find anything anormal related to the bluetooth (of course, it's off) which led me to think that maybe the graph is measuring something else.
Someone could say that it's fault of some app or even of the Play Services, but I tested even with every Google sync service disabled and nothing changed: the drain continued.
Looks like something the cause is really something system-wide because it's causing A LOT of apps misbehaving in this peculiar way.
I tried using the Battey Historian Tool, but I didn't manage to extrapolate useful information. The misbehaviour seems to stop after a reboot and after it recharged completely. Even disabling wifi and data gave no effect.
Here some screenshots of stats:
In summary, I could really use an hand in diagnosing what the hell is happening here because I am not understanding anything and I saw my fair share of wakelock problems, but nothing like this one. I'd like to undestand something before trying a factory reset.
