Question smd Wakeup - Samsung Galaxy S21 Ultra

I notice on GSam that smd Wakeup tends to run for quite a while in the background keeping the phone awake. I can't find anything on this and how to stop it. I assume it has something to do with sensors. Can it be stopped?

You really can't find anything?

Battery Drain Problems

I have been having some real battery issues with my phone.
I have a Nexus One, Kang-o-rama 1.2 SP2, CM7.
The issue is that when not in use and the screen is off, I have some serious battery drain. When I open up the battery info on GB, it shows that there is some process not letting my phone sleep. After 20 min and after 4 hours.
So thinking it was a rogue app, I uninstalled all my downloaded apps, thus leaving only the stock ones. However I STILL had the issue. Then I downloaded BetterBatteryStats and this is where I found something interesting. It showed me THIS. "Notification Lights" is constantly running. It is what is not letting my phone go to sleep and thus draining my battery.
I checked all my apps and cyanogenmod settings, and all my notification lights options are disabled.
So what could it be? How can I get the notification lights process to stop draining my battery?

Help with Battery Life

Hi guys, I'm worried about the battery life of my HTC One.
When the phone is on lock mode, meaning screen is off, within one hour battery can go down from 1-3%. Power saver is on, brightness is auto. And 4G/LTE is on.
Also, I only play around with my settings, checking out GSAM battery monitor, within 15 minutes battery can go down 1-2%.
Now it's been 6 hours 22 minutes since I unplugged from charger, battery level is 74%.
Is it normal?
Thanks.
Gsam should be able to tell you where your battery is being used and what app. Look at what the offending app is (most likely Google maps and Google+ or facebook) and use an app like greenify to hibernate them when not in use.

You do realize that the phone is still doing stuff when the screen is off, yes? Syncing e-mails/facebook/news stories, communicating the the network, etc. Even if the phone were completely off, lithium-ion batteries will still deplete(albeit very, very slowly) over time. 1-3% loss in an hour is pretty normal in standby. If you're really concerned about it, you can check out an app called BetterBatteryStats and it'll show you what's waking your phone up from sleep and/or preventing it from sleeping to help identify apps whos sync settings are too aggressive.
Your battery has depleted 26% in 6hrs 22minutes... you're losing roughly 4.08% per hour, at that rate it would take you ~24.5hrs to deplete the battery. Battery depletion is, can be, and should be accelerated when you're using the phone, so 1-2% within 15minutes while looking at a battery monitor... yeah. The more stuff you do with your phone, the sooner the battery will run out.
TL;DR: your battery life is fine.

Thanks for the info. However I noticed in some threads that for certain people, their HTC One can last for 1 days 9 hours. For example:

I'm guessing you're a heavy user!
What apps to you have installed? how many apps to you have?
My phone lasted 1 day and 9hrs on one charge with moderate internet use, txt messaging, phone calls - and that was without power saving mode enabled.

It's going to be very difficult for you to replicate the results of someone else(and we are lacking a ton of information from that post--is he running a custom rom, custom kernel, are screen off/on profiles being used, what apps are syncing, how often, how many, etc).
Beyond usage, phones can vary greatly from within the same model based on the manufacturing process/location/materials. For instance, there's a thread in the General Section exploring the differences in various HTC One's screen maximum screen brightness. Even down the chemistry of the batteries themselves. I know from personal experience that one of the biggest impacts on battery life can be how strong of a signal you're receiving from your carrier. If you life/work in a low signal area, the phone will increase power to the antennae to maintain the connection whereas if you're in a good signal area, it doesn't have to work as hard.
Anyone use GSAM Battery Monitor app? Why does the battery usage % doesn't add up to 100% when you add it with the remaining battery % sometime?
Yesterday it's still fine. But today my battery usage % + remaining battery % only add up to 93%.

Most people use that app. I'm not sure why it isn't working 100%. Did you plug your phone in for a very short amount of time? That might make errors. After you charge it overnight everything should be fine. Try using it for another day.

In GSAM Battery Monitor, my App Usage is always the highest contributor to battery usage, usually around 85%-90%. Screen is only 10.8%.
When I dig deeper into the App Usage, Kernel (Android OS) 23.8%, and Android System 15.7% are the top 2.

Do you have Auto Sync turned on?

If you are referring to Facebook, email, and such, then yes Auto Sync is on. So Auto Sync is included in Kernel or Android System?

It's a standard Android feature. Auto Sync drains a ton of battery

So for those who can get 5 hours+ screen on time, meaning auto sync is turned off?
Btw, do you know what is AsyncCollectorListener wakelocks that come from Maps? It also contributes to high partial wakelocks percentage most of the time.

Question What battery saver app do you use?

Hello,
I would like to ask you guys, what apps do you use to save your battery?
Naptime? Anything else?
Nothing... I don't need to install anything to save battery. That being said, I USED to do this with apps like Greenify on my Galaxy Note 3 (so like 9-10 years ago). But I had stopped doing that a while back as doing so had only lead to even less battery life lol.
to be honest, the best battery saver is to uninstall the native Facebook application from your phone. it eats up battery like anything. you will see a noticeable improvement on your daily battery performance.
I've tried naptime and I've not really noticed a huge difference, at least in repeatable conditions, i.e. overnight. Same with Galaxy max Hz, although i like the additional controls that the latter gives
Love Bixby routines to switch to 2G when at home or activate batter saver when sleeping and not charging. Rly good stuff.
I don't use anything to limit battery consumption, but I do use Accubattery to set an alert when my charge reaches 75%. Reducing depth of charge and not charging to full 100% is a way to reduce battery wear, so ultimately that extends battery life.

I kind of do something similar. I've got a Bixby Routine to shut off the smart plug that the charger is plugged into when the Battery percent reaches 80. Unfortunately, Bixby routines isn't very reliable.

I use Accubattery as well to monitor temp and charging.
If you use any power management especially 3rd party ones it can cause erratic behavior and may create conflicts that use more power than they save.
I deal with power hogs directly by either adjusting settings, disabling them or firewall blocking them.
Certain apps like Brave, Gmaps I manually close out when done or will they continue to poll the internet in the background and use power.

You can just turn off all notification and disable(deep sleep) in Background usage limits.
I’ve been using AccuBattery with IFTTT to shut off a smart plug at 75% for several years now to extend my phone’s battery life. This has been very reliable, it runs every morning before I wake up.

what do you mean disable? add facebook to deep sleep list? I noticed it's not working, even if I but it in deep sleep list I still get notifications. And do rly disabling notifications for facebook app improves battery? any source about that?

No, no. The first person essentially said to uninstall that crummy, built-in Facebook app and then to put some apps that you don't need notifications for into deep sleep mode. The second person mentioned the same thing with different wording.

Soli & Touch to wake battery consumption

Hi, I've bought a sealed p4xl off eBay and the battery life seems "ok" compared to my p3xl.
But I've noticed a major battery drain with soli radar on (ambient display always off), I have the music gestures and the reach to wake.
Is that what's causing the drain? Or is it because of the "tap to wake"? (Also why is it tap to wake instead of tap twice?)
Some reviews from users that have tried with/ without the functions would be nice.

In my experience tap to wake does not cause any excessive battery drain. Music gestures and reach to wake ( or anything soli related really) will cause extra battery drain. Lift to wake may as well.
Hey. I have a Pixel 4 XL and the battery lasts for a day, and I charge it over night.
I have ambiente EQ, 90Hz, motion sense, tap to wake and lift to wake enable and various apps running on the background. I usually get 5 hours of screen on time.
I would recomend you to download Accubattery and see the battery health. Maybe the battery needs to be replaced. Mine is at 92% of health(almost new). If it is below 80% you should consider replacing it. Here you have a link to ifixit webpage. For heating I use a hair dryer instead of their special kit. It gives the same result.
If you still need more battery, maybe turn off Motion Sense and turn on battery saver mode. Do you have adptive battery turn on?
Maybe there is an app using more battery than what it should or it is crashing and drain your battery.

Question Sensors battery drain when sleep tracking

So it seems that I have sensor issue with my phone. Especially over night when using Sleep as Android. It can easly it up 30-40% of battery in night. I checked it with better battery stats, and it seems that significant motion detector(sns_smd) and proximity sensor and accelerometer are using a lot of my battery. Anyone had problem like this? I am wondering if this can be software issue and if it makes any sense to try any other OS/software. I think I have this issue on A12 all the time, even did factory reset, installed kernel, etc, didn't help it. I think on A11 it wasn't happening, didn't try A13 yet. Any idea if other custom OS can fix this? Or maybe this is hardware issue?
Check some device info app how much is your phone discharging(in mA) in idle and during app running. In idle it should by ~100-200mA.
I don't think sensors are problem as they usually consume almost nothing.
You can use apps like 3C CPU manager for disabling CPU cores and minimize it's frequencies over night when Sleep app is running....it should help decrease battery draining.
Actually, I am using my mi band - and it seems that issue here is this, like when bluetooth is enabled and anything is connected there is huge battery drain. Testing now for one day with bluetooth off and I got 2h SOT and around 1h socials and just 44% battery used, so issue is there for sure. With bluetooth and my mi band connected I would get already 70-80% battery used.
