Nightmode healthy for battery / display? - General Questions and Answers

So in CM 11 there is this daydream option with a dimmed clock. The background however is not fully off but glowing very lightly. I was thinking of recharging the S4 Mini over night while leaving this mode on.
1. Is this healthy for the battery when it is charged longer than needed over night? Also the nightmode is sucking always a little energy.
2. Is this healthy for the display when the background is always glowing a little. Should I search for an app which is completely dark in the background?
Thanks guys

another way to save battery..and your eyes too

i downloaded this apps name
screen filter
it will reduce the brightness of your screen that is far more better than the android brightness..just dont set the brightness to 0 because it will turn your brightness off
thanks
will try it
works especially well with the "darkness" script at night, as mentioned in This Thread Thanks to Adolf1994 my LED will not blind me at night any more! (script only for rooted 2.1 and above)
how does the app work? and how much battery can it save, for example, a day?
Just what I wanted for day-to-day use.
I prefer renderFX's "night mode" for eye-saving, but this is good for battery-saving. My display is set at 0% and still is the most battery-hungry thing on my phone...
thanks
you reminded me that there's such a app
very useful

WORD OF CAUTION!!!!!
DO NOT LEAVE THIS APP ON WHILE YOUR PHONE SLEEPS!!!
I haven't determined that this is the culprit, but last night I went from ~80% to ~25%, all the while having WI-FI off (I have 3G off always anyway), closed most programs, and had a screen filter on 30%.
I think the filter prevented the phone from fully sleeping or something....
Just some caution, please try it and report back.
I haven't experienced that and I've been using it for 5days..anyway in order to track the culprit,install an APk named process watch dog.

Actually, it will not save battery, if not drain it faster.
Here's why:
What this app is doing is applying a transparent dark filter over the screen,
so that you can look at it in a dark enviroment and not hurt your eyes from the brightness.
BUT the screen itself uses exactly the same power to light, but you don't see it, because the filter is there.
For example: if you set your brightness to FULL and then apply the filter and make it really dark, the battery drain will be the same as if you didn't apply the filter.
That's the way TFT screens work.
Now, this filter is running constantly, so it's a CPU stresser, thus battery drainer.
That being said, I love the app and I always have it on while I'm in the movies,
but I don't recommend it for daily use 24/7.
Thanks in the darkness it's just the best app

I use it every night and I don't think it drains battery noticeably. 1% per hour maybe?

Depending in your personal phone usage, it might not be a battery drainer, but, as I explained above, it's not a saver either.

how much battery does AOD use with just home button ?

i have the always on display set with just the home button showing....as i'm still getting used to finding the spot its in when the screen is off....and coming from a note 4 its what i always go to......but as i have a complete black wallpaper with only the home button showing on the lock screen....how much battery would that use ?
also...is there a way to have to use less pressure when pressing the home symbol to turn screen on ?
thanks in advance for any replies.
Setting/display/navigation bar and at the bottom is the slider to control home button pressure sensitivity. Don't know about the other question though sorry.
AOD battery use is negligible. If you're worrying about battery drain, then you shouldn't. Even if you used the full AOD features (time and date widget etc) you're only looking at 1-2% extra usage throughout the day. The home button alone would be using even less by that logic.
Also I'm not sure I understand what you mean about the lockscreen background. You can use any wallpaper you want and it will still look the same with AOD. Amoled screens can selectively turn on just the specific pixels it needs to display your home button and/or information while the rest of your screen is actually physically off so it will be black regardless.
right..thanks.....wasnt sure if always on display had an option to have a wallpaper too.......new to the phone
thank you.
My pleasure.
Enjoy your new phone bud.

Thats not entirely accurate, its more like 1% an hour.
Because of some burnin protections the AOD will wake yoir device few times every minute so it will consume more battery.

When I turn on AOD, my overnight standby battery drain is 22% (100% to 78%)
When I turn it off, my overnight standby battery drain is 2% (100% to 98%)
It might not be that much but that's the result of my most recent test.

Hands fully bright in AOD mode possible?

Hi all
Is there any way to even custom make a face with the watchmaker or the galaxy watch designer but keeping the hour and minutes hands fully bright as in full brightness when in AOD mode?
You see I just want to be able to check time on my motorbike when driving with a glance in fully sunny day and not looking for a shady place on the street:laugh:
Thanks

I think you can't control the brightness decreasing when the watch switches to AOD mode. I remember in Watchmaker there was a option to tune the brightness in AOD mode but it was never as bright as in normal mode.
What could help you is this app: Flaunt
It will keep your display on for 30 minutes but at a cost of battery life

I will have to try that! In the meantime, I think I've exploited a bug/glitch on my Galaxy Watch 3. I can't show it in a photo because of auto light adjustments, but it looks at least 1.5-2X as bright as the dim limitation.
I set my brightness to 5, with auto brightness on and screen timeout at 5 minutes - seems to consumer about 1% extra battery per hour.
1) In WatchMaker, set screen timeout to default, and 70% OPR in bright mode (15% is all you can do in dim mode)
2) With Tasker on your phone, set up an event triggered by time (i.e. 8AM - 11PM) that repeats every 5 minutes
3) Use the WatchMaker plugin to send that same face to your watch.
It may take a cycle or two to sync up, but what it does is tricks or freezes the watchface in something substantially brighter than the 15% OPR, I'd assume maybe 70% of whatever it is in brightness.
The hour and minute hand still update every minute. In fact, you will see the now frozen second hand move for about 3 seconds every minute as the time updates. I might just drop the second hand if I can't figure out how to hide it selectively. As an added bonus, the refresh doesn't activate the face, it will flash and the hands update but it remains in dim mode.
I think you can disable the vibrate notification for a face change. It flashes quite quickly on refresh - 1-2 seconds. I wonder if there's a way to disable the "white" flash on refresh? Otherwise, I'm pretty happy with it for a more usable AOD with faces that are otherwise hard to see at 15% OPR.
WARNING: Don't forget about burn-in. I'm creating a mesh overlay (basically 1 pure black pixel per 11x11 square) that will "rotate" every minute to duplicate the burn-in protection. Instead of shifting pixels, it will black out very pixel once every hour or two. Then I also have a rotation of black/dark gray screens with an equal number of colored faces.

Question Bad battery life, GPS & OneUI Home running in background

hello guys, i really dont know what to do.
yesterday I was charging my phone to 85%, almost didn't touched to phone until the morning(over sleep also - 8h of sleep).
i went to the bed with 65%, woke up with 55%. without AOD, on DND enabled.
I saw that One UI Home & Google Play Services is running a lot on background, There is something I can do with it?
Please help me. My battery is sucks

Question Always on display battery drain

Hi, haven't had a Pixel for a long time (last one was a 4 XL) so pardon my Aly question
Brand new Pixel 7 Pro, charged at 100% and went to bed with AOD on, woke up after 7h with 92% battery: is this normal?
PS: I'm used to Xiaomi 13 Pro with AOD off using almost 0% overnight.
Thx
I'd be very surprised if a phone really consumed 0% over 7 hours, WITH AOD on. Infinite battery life?
That said, sounds about normal, especially until the system sets.
I believe Xiaomi is sort of cheating with batt %, since in the morning stays at 100% even after 15 mins of usage
By the way, I disabled AOD and will test tonight.
Happy to be back to a Pixel though
Also note that if you put it face down on a flat surface it will activate DND, and do try the bedtime mode since it reduces battery consumption.
How do you enable bedtime mode?
Look in settings, it's under Digital Wellbeing
Thx
Battery will adjust with use, it consumes quite a bit more than normal the first few days.
Once it adjusted, for me it went down to 0.6-0.7%/hr. That was before I started installing apps though!
What about charging speed?
Is there a switch to turn on/off adaptive charging to have quicker charging during the day?
Nope, you have to settle for it. For me, it's fast enough to be honest...

Great for long term battery life.

It's not cheating really. Just their charging "design". If you keep a Xiaomi phone on a charger even after it charges 100%, it actually charges a bit more than 100% you just can't see it. So, from 100% to 99% is like not actually 1% of battery capacity but like 3-4-5%.

I noticed that, when on charge, if I simply turn on Do Not Disturb, the adaptive charging notification appears, but if I turn on bedtime mode, the adaptive charging notification disappears.

Disable global power management; it never did work right. Find the power hogs and deal with each on a case by case basis.
If you find the source(s) of the excessive drain and correct them, the excess battery usage disappears immediately. Close apps before you put the device in sleep mode.
Developer options > standby apps, if all buckets show as active global power management is disable. If various bucket states exist and/or those states can be altered, it is active. It can't be disable here; power management settings. Altering background battery usage in the individual app settings doesn't invoke global power management...
