Always On Display with Edge Only

Hi,
I realized that with the Always on Display and with the setting for Edge only, I still see the stars in the background (using the default wallpaper). Doesn't this mean that even more battery is being used than with the standard full screen Always on Display? Isn't it supposed to only use certain LED's on the screen to conserve battery? If so, is it not possible to have the Edge setting on and save battery by disabling the background?

You could try not using one of the built in live wallpapers, that's where the stars come from.
Hope this helps.

So does anyone actually use the always on display feature? Seems like it wastes alot of battery

Someone will help you

I don't personally, no point using the battery when your not using the phone, I just see if the led is flashing or not.

About 3% to 5% in my experience.

You can turn on AOD feature, but when you put the phone on the desk for a long time without touching it, just put a small piece of paper (sticky paper) over the top of the screen (above the proximity sensor).
That way the AOD screen will be turned off in a couple of seconds.
When you need to check time or notifications, just lift up the sticky paper and the AOD will come back on.
You can save several % of battery using this way.

That, or face down

Weird. Mines on with a custom picture ( I converted to grey scale ) and unplugged overnight i only lose about 3-5% total. I haven't tested without AOD but it can't be using more than 2-3% tops as I'm sure the system is using up most of the battery while I sleep.

I have a custom AOD and battery life is fine. Its good to glance and see the time without having to pick it up and unlocking.
If your worried turn it off or flip the phone face down. With quick charge on the phone does it really matter?

How does phone go into deep sleep with AOD on?

Hello everyone, I'm an S5 user but am wondering how can the Note 8 (and any phone with AOD by default in that matter) enter deep sleep mode (Doze as well) while the Always-On Display is nonstop active? I mean, the custom ROMs for my device have fully working AOD but the phone stays at the minimum frequency (300MHZ) and never goes to sleep while AOD is on. I'm just curious how it's done and if it would be possible to port for the S5. I'm no developer btw, just a curious guy Please quote this post if you decide to reply as I don't visit these forums as I got no Note 8 Thanks.

Bump agreed good question. Although I don't use Aod scared of screen burn in.

Don't know about infinity display, I don't like it but the usual AOD bounces the time around occasionally to prevent burnin

Yeah it bounce across the screen in order to not burn it. Also the home button do it (see any time lapse from youtube, it move slowly)

I don't think it's the phone that goes to sleep, I think it puts the apps to sleep. I came up with this thought after I noticed that my cooperate exchange email only updates successfully when the screen is on. There is a scan window for network traffic enabled by android's Doze feature though. So at that window, all network data transmissions are done.
It could be like I said all apps sleep that aren't actively needed. In my case, AOD and GMusic stay running for me.

Hm, in my case (ported ROM) the device just never enters 'deep sleep' state as seen in CPU Spy, can you check if while AOD is active your Note 8 goes into deep sleep?

Total state time: 60 hours and still got like 70-80% battery left xd (I want new phone :c, nah, not really, I got IR and removable battery now )
Well seems like it does enter deep sleep. Guess I'll have to either turn my AOD off until ROM dev fixes this or until I get the Note 10 (maybe), thanks!

Ah, yeah. Confused it with Wakelock Detector a bit

Is the fingerprint scanner enabled while the screen is off on stock rom?

After unboxing and charging my new Note 9 I immediately rooted the device and flashed a custom FW.
Can a person on stock ROM please clarify these questions for me:
1) Is it stock behaviour that the fingerprint scanner on the back is always on while the screen is off?
2) Does this feature impact battery life?
3) If it's stock behaviour how do I disable this? I tried changing the secure setting "biometrics_auto_wakeup_enabled" from 1 to 0 without any effect. But maybe there is another switch? I don't know.
Thanks for any help!

1) If I remember right, I have not changed any settings related to the scanner being enabled/disabled while screen is off, i.e. it would be at "default". I haven't even looked for such. For me, it does unlock directly even when display is off. (Edit: fingerprint seems to unlock from any state before homescreen, except in the lockscreen note writing mode.)
2) I haven't measured battery life yet, let alone looked for changing the feature's behavior for another measurement, so I can not really tell. However, standby battery life seems to be ok. I'm using the phone with very varying levels still, so hard to estimate well, but I'd estimate from the early daily %-drops that standby time is at least 4-5 days. So, I guess the feature doesn't drain the battery that much.

Just a small follow-up, as I finally got a decently "normal" (for me) day and a half with the phone, only one short call, text message, maybe 10 gmails received (but mostly read on PC), a bit of "usage" with screen on time probably less than 15 minutes in total.
Seems I could get about 7.5 days of standby time.
Screen settings don't matter much in this scenario (as the display is off most of the time). Other significant settings are: wifi off, BT off, 4G LTE always there, GPS always available, NFC always ready, fingerprint sensor always waiting for finger, the only extra apps that could be battery hogs are Flowdock and Steam apps (both seem to behave nicely, Flowdock was nasty on my previous phone). Using the LED cover. (Quite the "default" setup with a relatively small number of installed apps or changed settings.)
In a way, that result is good. But on the other hand, with similar setup (minus Flowdock and LED cover, fingerprint sensor only works when display on, but add an extra email account on samsung email app with polling checks), my Galaxy S5 was getting about 6-7 days standby time, too, and that with its original battery (and the phone was bought pretty much the day when it came available here). Note 9 having much larger battery, and presumably better SoC (at least they always claim lower battery drain in idle from each CPU after CPU generation), better Android version... kind of "meh" result from Note 9. However, I did tighten some settings on that S5, like reduced email check frequency and such, which I have not looked for on Note 9 yet. And possibly will not look for, that 7+ days is good enough for me.

Brand New Pixel 5, battery seems awful

I upgraded to a Pixel 5 because my Pixel 2 XL was experiencing hardware issues and was going to die. Among them were battery degradation that was leaving me with maybe 3 hours screen on time from a full battery.
The Pixel 5 so far has been barely better. Additionally I went to bed last night with about 79 percent battery, I woke up around 48 percent. I have no idea what's going on but this is fresh out of the box, I got it Thursday like everyone else in the USA. Is this normal? Can anyone suggest how to figure out what's causing this drain?

You might wanna FDR and start fresh. Sounds like something might be hung up from the setup. All reports about battery have been stellar so far.

I did do the setup where you transfer data from your old device. I guess maybe I need to bite the bullet and do it fresh.
Do you know anything about the... I think the setting is called Always On Display or something like that. The setting where when the phone is locked and the screen is off, it always displays the time and notification icons. I had it on my Pixel 2 and it worked great, it's almost necessary for me at this point. I have it turned on also on the 5, but it seems...finicky? At times it shuts off, especially at night. I used to keep my Pixel2 on my nightstand (just laying flat, not on a stand or anything) and the time would be on all night so I could see it at night if I woke up. With the 5 it seems to shut off in the dark. Additionally periodically during the day it sometimes all of sudden jumps to really high brightness, then back down to dim, sometimes it turns off completely and I have to hit the power button or the fingerprint reader to unlock the phone. Even doing the tap to wake doesn't work. Actually that double tap to wake doesn't seem to work at all regardless.
Any info on any of those issues you know about? I've been searching around and I've found basic references to some stuff with that always on display but no direct threads or anything specific.

Not too sure about AOD, I just went with defaults. But last night, my first with the P5, I unplugged at full charge and 7 + hours later it was at 100%. That's never happened but it was face down and on DND. Nonetheless, check out this thread, download the app, non root needs certain permissions, and let it run for a day or so. It should show you what you need to know.
https://forum.xda-developers.com/showthread.php?t=1179809

Did you make sure to charge the phone to 100% before using it??? These lithium ion batteries need to be charged to the max if you want them to last. My pixel 5 wasn't even fully charged it was somewhere around 65% out of the box. I would leave it charging for a half hour or so once it hits 100% just to be sure.

I mean.. this is mine.

That's incredible. Next time include all 3 screens please. I could get 12 hours of on screen time all on wifi. Let's see you get that on 5G.
Real world battery is best.

I'm seeing great battery life like many others.
I started using AccuBattery Pro. How accurate is the estimated capacity given by the app? Anyone have any experience?
For me the app is estimating battery capacity to be 4,490mAh which is obviously way above the advertised capacity.

Coming from a worn out pixel 2xl this 5 is fabulous the battery is great. I accidentally left the flashlight on for an hour and it barely drained it. The battery is exceeding my expectations. Screen on time at 5 hours and I'm just at 49% with 10 hours remaining. I'm satisfied for sure

Also on Verizon, but no issues for me. Battery life has been amazing, I didn't charge last night (unintentional) and I was going until this afternoon, with mostly light usage. I've never experienced something like that before.

So in case anyone is interested in this, I actually have a hardware defect that was discovered by a user on reddit.
Link Here
The gist is that the proximity sensor is (i think) detecting that something is up against it all the time. This creates issues with things such as the phone screen not turning on when you pull the phone away from your ear when on a phone call, Issues with tap to wake and lift to wake not working, and Ambient display/always on display (whatever it's called now) constantly changing brightness and/or shutting the display off completely. Literally the phone could be sitting there on the table and all of a sudden the always on display goes to max brightness, then down to dim, then up, then shut off completely. I assume all this craziness is hitting the battery hard.
I am trying (although frustratingly) to get Verizon to exchange it for a new phone. My phone acts exactly like in that thread. There's a proximity sensor app that will detect when something is near it and change color. Mine is solid colored and won't change unless you press on the glass near the sensor. Just in case anyone else has this issue come up, there it is.

I'm at 5 hours of screen on time and 17 hours use. The battery is exceptional and I can dedicate more time to work online because of it.

It sounds like you have ported a troublesome app over from your old phone to be honest. I think a factory reset would fix it.

Question Always on display doesn't turn off when the phone is on it is face or the sensors are covered

So I had many Samsung phones before the S21 U and I never turn off the Always on display. When I put the phone (not the S21 U) on its face or cover the sensors, the always on display turns off, but this is not the case with the S21 U. AOD never turns off even when the phone is on its face or the sensors are covered. Is this a bug? can I do anything about it ? I want it to be like the old way.

Its not a bug, this has been the case since the S10.

Well, it's not a bug, but it's also not an unavoidable feature like the other dude said.
Go to settings, scroll down to lockscreen, tap "always on display", then you can choose always on, on for 10 seconds after tap, or show as scheduled.

It would be nice if Samsung let you choose more than one AOD option. It would be great if you could both schedule AOD on hours plus enable tap to display for 10 seconds.

Actually it is indeed an unavoidable "feature" that was introduced since the S10 series. He's talking about the fact AOD used to automatically switch off when the phone is in a pocket or face-down. That is, despite the setting of "Show always" being toggled, the AOD would still switch off when in a pocket or face-down. The reason for this being that if it's in a pocket or face-down, it's pointless having the AOD on. The advantage of course is that battery life is saved.
An obvious example scenario is when one is out and about for say a 14-hour period with the phone in their pocket or face-down about 50% of the time. This would mean the AOD is automatically disabled for 7-hours (while in the pocket or face-down), saving about 7% of battery life. To clarify, the AOD automatically turns on for the other 7-hours when the phone senses that it's outside of the pocket or face-up. I've come from the S9+, and I can certainly confirm that this feature saves battery.
For some reason, since the S10 series, Samsung have disabled this feature for AOD. I can't find any information as to why, but it must be related to the proximity sensor and how it interacts with AOD. Otherwise another reason is that Samsung felt no one liked the feature (can't really imagine why) and disabled it without giving any option to enable it.

Ah I missed the part where he was specifically concerned about the proximity/light sensors shutting the AOD off, just thought his problem was it just never turning off.

Please reconsider - are you sure the feature actually saves battery (face-down or covering sensors turns off AOD)?
Remember we now have a very good display with adaptive refresh. Maybe Samsung designed the screen to be good enough in AOD to actually use less power than running the proximity sensor (to turn on and off AOD) all the time.
So it's a false comparison above - it's not "free" energy savings when you had that feature. The phone had to use power to activate the proximity sensor to know whether to turn off AOD, and it took power to turn on/off throughout the day. But maybe now, why should Samsung bother with that, if they figured out it's less power to just have AOD all the time and not power the prox sensor?
Bottom line, why waste power on running the prox sensor when you can instead use that power to show useful information?
This is speculation, I don't know the actual power loss caused by the missing feature. I just want to correct the assumption that it's free power, when it's not.

I suppose that could be viewed as a good point, although it's actually still a disadvantage or "downgrade" compared to having the original "power saving" feature. This is demonstrably proven (at least for me) given having AOD enabled loses about 1-1.3% battery per hour, which is similar to previous Samsung phones. With AOD disabled, the battery loss is closer to 0.3-0.7% per hour.
To clarify, your argument is that having the proximity sensor activated while AOD is enabled may actually use at least as much power as always showing the AOD when the phone is in standby. Again, I would say this is a "downgrade" compared to previous models, as the proximity sensor should never use this much power (and we know the amount of power the AOD uses is similar to previous models, as demonstrated above) - if it does, then it's arguably a "design flaw" by Samsung. That is, they would have made the proximity sensor a "battery hog" in a relative sense.

Odd, my AOD set to "touch to show for 10s" doesn't even use 1% in 20hrs with 8-10hrs SOT. Snapdragon US model from Google Fi.
You'd think samsung would have more consistency in these, especially by now.

AOD uses very little battery*. Cell standby and device idle together use more.
*if you use a simple clock and don't have all kinds of needless garbage.

I should probably clarify a few things here.
-With AOD set to "touch to show for 10s", the amount of battery AOD uses should be entirely dependent on how often you enable it by tapping to toggle it on. If you tapped it 1000 times in 20 hours, verses 10 times, it would obviously be quite a different amount of battery use.
If the AOD is set to "show always", it could be viewed as essentially the equivalent of continuously tapping to show every 10 seconds for the 20 hours you quoted. It's therefore clear that it would use more than 1% in 20 hours!
-My description of the amount of battery loss from AOD being set to "show always" verses completely disabled was actually regarding total "standby drain" per hour. That is, with AOD set to "show always", the total standby drain per hour (eg. overnight) appears to be around 1%. With the AOD completely disabled, it's closer to 0.5% total standby drain per hour.
The above numbers have been fairly consistent across all Samsung smartphones I've come across, although I suspect the S7 was one of the best (since 2016) in terms of least overall "standby drain" per hour even with AOD set to "show always" (if I remember correctly, it was closer to 0.5% per hour drain with AOD always toggled on, and 0.1-0.2% per hour drain with AOD disabled).
Note that these figures are without any "de-bloating" or "rooting" of the phone.

My previous phone, a Pixel 2XL, I had set to AOD always on. The phone would turn the display off when face down and even when in a holster on my hip. At night it would stay on all night as a night light/clock right next to my bed and my charger would come on via timer an hour before I would get up to recharge.
It’s very disappointing that the S21 Ultra, brainlessly just keeps AOD lit nonstop despite the fact that it’s a deluxe phone with enough sensors to be programmed just like the Pixel 2XL, which did much better with AOD and its effect on battery life. I’m hoping Samsung fixes this in an update real soon.

The power used to light the display is very small vs the background processes already running.
Pixels have no SD card* slot because Google wants you to be cloud dependent.
You aren't viewed as a customer by Google... you're the product. Getting off their factory devices is a start in the right direction.
*No SD card slot is completely unexceptable.
The SD card is the data drive or should be.

*No SD card slot is completely unexceptable.
The SD card is the data drive or should be.

When I first got my S21 Ultra I set AOD to always on and battery life suffered greatly compared to my previous 2XL. The S21 Ultra doesn’t have an SD card slot either, which has nothing to do with my comments about AOD performance between the 2XL and the S21 Ultra. You are correct, it’s great getting away from Google, but the only real alternative is an iPhone or custom ROM with Micro-G on an Android phone, which again has nothing to do with AOD performance.

It's irritating Samsung chooses to do that on some of their phones. Worse it varies from year to year with the same model sometimes too.
AOD in it's always on mode at night if you're not using the phone should use roughly .75-1% an hour. Usage isn't always reported correctly to the apk responsible. Lovely isn't it?
Try clearing the system cache.
If you did any major firmware updates a factory reset is in order otherwise it's not going to get to the root cause most likely.
Samsung's are notorious for this kind of behavior but it can be sorted out. Cloud apps including Google Backup Transport are prime suspects.
Disable Google Firebase and all carrier, Samsung, Google feedback for starters.
Karma Firewall is very useful; a VNP firewall that uses almost no battery, no ads... true freeware.
It's logging feature may not work with Q and above. An adb edit to correct that may be possible, not sure.
A package blocker is also very useful and a powerful tool for unrooted phones. I've used this one for years with zero issues.

Once I disabled full time AOD my S21U, battery life is no longer an issue. As I stated previously, I would like to see a Samsung software update making their AOD perform similar to the way it does on a Pixel 2XL.

It's not AOD.
Samsung's can be... complicated.
This is how much AOD uses on my 10+, it's an accurate estimate. This is after I spent a lot of time to optimize it ie get the bugs out.

A few additional points/queries about the S21 Ultra:
-I've calculated the total extra battery % loss per hour with AOD always enabled to be around 0.5-0.6%.
"blackhawk" post above suggests that for the 10+ phone, the loss is more around 0.3-0.4%. This appears to correlate well with what I've read regarding the AOD on the S21 Ultra running at 120Hz (which would increase battery use compared to if it ran at 60Hz, which the 10+ phone presumably runs at). It's a pity this is the case, as I don't see any advantage for AOD to run at 120Hz. Perhaps in a future update, Samsung could reduce this to 60Hz on the S21 Ultra.
-I note a couple of users in this thread "hoping" that a future Samsung update will allow the AOD to automatically switch off when face-down or in a pocket/bag. Unfortunately, I don't see this happening, as this feature appears to have been "lost" since 2019. That is, this feature was last present on the S9/Note 9 series of phones back in 2018. All Samsung (flagship) phones from 2019 to present have lost this feature.
-Does anyone know of a way to change the AOD font size (without installing extra software)? Reducing the font size would surely be another way/option to save battery life while having the AOD always enabled.

Wow, you got your AOD power consumption down to 3%! The first week I had my S21U, AOD was using 25 to 30% daily I believe. Can you please tell me what you tweaked to get your phone’s AOD power consumption so low? That’s better than on my Pixel 2xl.

I'm not sure what is causing that. Something is running in the background; the phone's not going into deep sleep. Maybe a messaging or cloud app. Usage apps can misreport which apk is the cause or it could be a dependency.
Try it in safe mode to rule out 3rd party apps.
The Google system apps are prime offenders as can be the Samsung apps.
Try clearing the memory cache then see which apps pop up first. My version of Device Manager can do that; I've used it to find rogue apks like that.
