Hello,
I was wondering how happy you guys are with your S21 battery life?
I used a Huawei P30 Pro before. When going to bed, I usually had 30% battery left.
With my S21, I now usually charge at 7PM. I cannot imagine, that my usage habbits have changed much since - especially since I was unhappy with the battery life from day one.
I did some Analysis:
Idle:
With battery-saver (Samsungs; in Settings) on: 0.73%/h - Not bad, I would say.
With battery-saver (Samsungs; in Settings) off: 1.93%/h -Not good, I would say.
Now, do I want battery-saver on? Not sure... Why did I buy a first-class device when limiting its CPU and refresh rate?
Screen-On:
I know that here, comparing is difficult...
According to battery historian the Screen-On discharge-Rate is 16%/h. That would give me a screen-on time of 6.25h - I am hot sure if this is good.
How is it for you?
What I also notice in battery-historian is, that when switching off battery saver (green bar below) I have significantly more Userspace Wakelocks. Yes, I was also using the phone, but if you observe the yellow marked time around 12-1PM, there are wakelocks without me using the Phone.

Wakelocks:
In minutes, it is not so much, but in counts... 2500 seems a lot.
Is this normal? Or is there something, I could improve/fix?

I'm not having anything like your experience. I am a US user with Snapdragon in case that matters. You don't mention how much typical daily screen on time you have.
I am sure there are more expert people here to interpret all of your captured data. But I am wondering about fundamentals. Have you already configured:
Battery optimization for all apps that don't require background operation?
"Always on" display?
Display timeout to something minimal? (I set mine to 2 minutes; I can't tolerate anything shorter)
Hello,
that is interesting to hear.
Screen on time is usually around 4h. Then the battery is completely empty.
The 2%/h in "idle" mean already on a day between 7am and 10PM 30%. So, the idle usage is about 1/3 of my drain and thus clearly worth improving. But especially the Screen On drain of about 20%/h is too high, I think. This morning I used the phone for below 2 minutes and the battery was already at 98%.
Regarding Apps in Standby: The phone has put many apps automatically in the list of "APPs in deep standby". I have manually added some.
I have only few Apps never in Standby:
Kalender, Kalendar widget, Telegram, Threema, Whatsapp.
Always on display is off
Display brightness is set to around 50%. Refresch rate is "Adaptive" and Timeout is 2 minutes.
So, I think this is all reasonable.
Any ideas?
Best regards,
Hendrik

Hi, AUHD(best on for battery life) or older SW? I have with first beta 5-7h sot, while night when I don't use phone I have 0,2%/h drain, with screen on max 7-9%
Wow, more than Double for me.
What is AUHD?
I have all updates installed.
Software version, if you have latest version there will be something wrong with your phone, try to find apps causing that high consumption. And never put any app to deep sleep or sleep mode, and don't use battery saver. This has for me other effect than lower consumption. These three things I have disabled - wificall,volte and 5g, nothing more.
And on WiFi turned off mobile data, GPS and bt.

I have the S21 from the start I have always held 1 day and 18 hours on average with 2 hours of stupidity, and I do not deactivate absolutely anything, gps, WiFi, 5g, Bluetooth, I leave everything on, and it works perfectly ... .... For the adaptive battery to work properly, it needs 7 to 10 days minimum ..... It does not do in a day .... And personally I have had all the galaxies since the 1st galaxy , I got them all. And many fail to configure it correctly. And above all, gave him time to configure himself on energy management.

Whit yours sot I have to charge phone every 8h, 3 times a day, this is not what a customer needs... I see you are fan of Samsung(I was also- S6,7,8,10 and now 21) but comparing to other brands you have sot from 5-11h with no restriction.
For last I will mention android auto, first time in 3 years I see the first device what can manage android auto, so many lags and no interest from Samsung to fix it...
I will also mention the good things because of them I still have s21, display visibility in outdoor, speaker sound, cameras.
Just use power saving mode with 120hz enabled and u will get 5-6h of SOT easily.
Hello,
I have factory reset the device now. I got 6h SOT now (twice of what I achieved before.
No Idea what the reason could be, though.
The only thing that I am not yet using again is Nova Launcher.
Greetings,
Hendrik
I also came from Huawei P30 Pro and I've the impression that I had more battery before.
I've a S21 (Exynos version) and I think SOT is around 3-4h.
Did you let everything in automatic like "smart wifi", 5G, Bluetooth, ... ?
I don't understand questions like this. S21 is basic model and obviously has shortest battery life. If you want a big SoT, open
Battery life tests - GSMArena.com
www.gsmarena.com
customize usage pattern and choose your phone for example S21+. If you have already bought S21, turn on 60 Hz screen, lower the brightness, reduce the processor frequency, turn off unnecessary communications and functions. I'm very happy with battery life for my tasks ))

S21 has a battery of 4000 mAh and a screen of 6.2 inch
S21+ has a battery of 4800 mAh with a screen of 6.7 inch
S21 Ultra has a battery of 5000 mAh with a screen of 6.8 inch.
Ok, S21 has the smallest battery but also the smallest screen.
I let everything in automatic mode like you can see on the attached screenshot.
I don't see the problem if we ask to someone if he let everything in auto or if he plays with Bixby Routine to optimize his smartphone.
I am also happy with this smartphone and its size but when I'm leaving to a place with power, I know that I need to take my power bank even in Batter Saver mode
I also thank you for your link. I can see, according to test result, there is a difference of 7h between S21 and P30 Pro. I don't have this impression
S21 has a battery of 4000 mAh and a screen of 6.2 inch
S21+ has a battery of 4800 mAh with a screen of 6.7 inch

4000/6,2 = 645 mAh per inch

I don't know why in a place without power, for example, an option is needed "Turn on Wi-Fi automaticaly", Wi-Fi is looking for a router all the time.

I've loved my Galaxy SII right from day 1, but the phone's battery life has made it a complicated relationship.... I'm hoping to share my experience as a heavy user and how i'm dealing with the battery.
My usage:
I would fall into the 'power user' category. I'm rooted, on stock 2.3.4 (the update to 2.3.6 was pushed to my phone, but obviously failed). I'm often streaming audio podcasts, using Waze (a social gps program), and checking twitter and online forums and the occasional email or text. Bit of youtube in there as well. Bluetooth is on 10% of the time, wifi always, screen 1 notch below max brightness, no 'fetching' widgets.
My last phone, the iphone 4 had better battery life, but not incredibly so. During heavy use I would get ~6 hours. Standby was closer to 20 hours. I still had to charge at some point during the day, but it's different with the GS2.
Let's take a look at the Battery Usage in Settings....

With 4 and a half hours of usage, i'm down to 13%. That means I'm up at 8:00AM, and by 1:00PM my phone is dead. It would almost be hilarious if it wasn't so sad... Charging has become a critical part of my daily routine. I'm using an external battery pack (more info below) and charge off a wall socket
Solution so far:
I've been using the Energizer XPAL4001, a 4000mah external battery for $58.00.
The thing is great, and I obviously wouldn't make it a full day without it. However it's a hassle to have to lug it around which is why i'm considering getting the extended battery which I was hoping to avoid by getting the external. But it looks like I do need both solutions.
Solutions I'm considering:
I'm about to pull the trigger on a3500mAh Extended Battery + Cover off of ebay. It's going for $11.00 with free shipping, so the price is certainly right.
What do you guys recommend? Has anyone tried the battery I'm looking at? It doesn't have NFC, but it's $11. I'd love to hear from other power users and how they're dealing with things.
PS. Still love my GS2
I'd recommend using your phone less!!
Try an i9100 rom, much better battery life.
You are expecting too much if you want it to last all day long with that much usage.
Doesn't look like your phone went into deep sleep not once.
Try flashing UnNamed 1.3.2 or 2.2.1 and a custom kernal and use SetCPU to lower clocks/volts.
This should help you in increasing the battery life a little more.
Have you checked this thread? http://forum.xda-developers.com/showthread.php?t=1308030
What about the Korean 2000mah battery? You can see my posts on this page for more info: http://forum.xda-developers.com/showthread.php?t=1281777&page=11
It would be helpful to know how much screen time you are getting. You can access this by clicking "Display" in the screens you have posted above. Your battery is dying incredibly quickly. If your screen time is less than 2.5 hours you may have a rogue app that is running up your cpu. Use CPU Spy and better battery stats to help diagnose.
Sounds like you are such a power user that you might want to consider one of the 3500mah batteries. If you don't mind the size that is. Search the accessories forum to make sure you order the right brand as some cause boot loops. You will also lose NFC.
Good luck!
thanks for the replies everyone.

Sorry, but no. I would carry a second phone before using this one less. But it's a reasonable recommendation.

I'm not expecting a full day of battery life, but 4 and a half hours of usage in undeniably on the short side. Thank you for the insight on deep sleep etc. I'm newish to android and appreciate a skilled user's input.
As for flashing a rom, I'm really waiting for an Ice cream sandwich release before going that route. I'm aware of underclocking etc but think that I might get better results by getting the extended battery.

Time on: 2h 57m 20s
I will look into those 2 apps.
This is what I have for today with better battery stats.
/\ were you using the GPS? I was for most of my 4 hours of life.
what were you doing with your 2 hour 26 min of screen on time?
Hmmmm, 3 hours of screen on time sounds about right for the battery life you are experiencing. As far as that particular battery, I'm not sure... I would play it safe and purchase one people are linking to in some of the threads that are confirmed as working. The other thing you have to consider is cover fit- which is another reason to go with one people have posted experience with in one of the "Accessories" threads.
BTW: Not sure but the Waze app may be utlize GPS in a way that it consumes more battery than it posts in your battery usage. Not sure though.
Also, are you leaving the screen on unnecessarily, like while listening to a podcast. That's a pretty intense amount of screen usage for such a short period.
Let me know what you decide
Just for Reference
Here's my usage with the 2000mah Korean Battery.
Screen is off during podcasts, on during GPS. Waze affects my battery about as much as the google Maps/Navigation app.
As for the battery, I've heard others buying batteries that have been $50 and up, I could buy 4 of the ones i'm looking at for that price.
Someone out there must have tried this battery before.... I'd like to hear what they say first.

Install BBS (link) and cpuspy (link) today and then tomorrow make sure to reboot your phone before unplugging and doing your daily routine.
Once your battery reaches 20% post the BBS dump and screenshots so we can analyze it better and see what is draining your battery so much and how to improve it while you wait for your new battery.
I highly recommend flashing a UnNamed or ShoStock since it removes bloat and also SetCPU to lower the volts and set some profiles.
You said your new to android, so listen to others that have used it longer.
PS. Ice Cream Sandwich will be a while so don't hold your breath...

I use gps for about a minute today. Most of my screen on time is messaging web surfing facebook and twitter
Was your screen at max brightness or autobrightness? Autobrightness tends to set the screen way too bright.
After all, your battery history indicates 74% of the usage was display - so I think you may just have the brightness way up.
Full brightness + GPS + CPU usage is brutal on the battery, that brings total current consumption to somewhere around 650 mA. (On the Infuse, the battery would slowly discharge with a 600 mA charger at fullbright + GPS. The GSII just barely keeps ahead with 650 mA charge current.)
I'm getting between 26-32 hrs with the config in my sig.

Alot of good advice in this thread! I highlighted above what I think is killing your battery. Go with a debloated stock like ROM, research a bit on cpu schedulers and go with a conservative one, turn the brightness down and you will be on your way to duplicating your battery life. ;
Use Siyah kernel and the Thunderbolt (TB) script. They'll do wonders for your battery. As for brightness use auto or half way. We're lucky to have such boss screen with crazy brightness. anything above 70% hurts my eyes in doors lol. Auto should be 90% effective for your day to day use. Also try to avoid apps that sync or fetch data constantly and set things to push or to auto-update every 3-6hrs instead of 15min-1hr. Those murder ur battery.

I'm considering this, but I'm going to see what kind of increase I get off an extended battery alone first.
I've found it harder than I thought to try and compile battery statistics...however, that being said, what kind of times are you guys able to get, say with average levels of use?
I think the most relevant stat is the one for screen on time, the screen seems to be the biggest killer of battery.
In my most recent use, Better Battery Stats tells me that I've been on the battery for approximately 1 day and 12 hours, and that only 5 of those hours have been for the screen on. I'm now down to 15% battery, so in general, I think that 5-7 hours of screen-on time (with the lowest brightness) is what I usually manage.
How.about the rest of you guys?
how do you work out how many hours the screen has been on?
i mostly use my flyer as an ereader during the week...i get about 4 days usage from 100% to 20%, and have airplane mode on mostly

I use a very useful app called Battery Monitor Widget. I highly reccomend it. Its able to split my usage between awake time, screen on time, wifi on time, and Bluetooth on time.
That sounds about right for me as well, 5-7 hours of active usage. Obviously depends on what you're doing, but I use it extensively and struggle to get more than 7 or less than 5.

Yes. So from our two experiences, 5-7 with screen-on time is somewhat standard. This is why I'm somewhat bemused when people say they've been using the battery for a week! I'm left wondering...were they using less than an hour of screen-on time each day?
If 5-7 hours of screen-on is the average, then my definition of light-to-moderate usage is when I can stretch that out to two days before recharging. Keep in mind that my 5-7 stat is with screen brightness on the lowest setting, and with Juice Defender.
battery depends on use. I have had it last 48 hours with 6 hours screen time and I have had it go in 16 hours with 3 hours screen time. With all the diferent variations of this device, as well as custom roms/kernels and GB vs HC I am not certain there can be an expected battery life span

Yes, I think 5-7 of screen-on time is about standard.
I ran my test and used my Flyer (wifi only) mostly for light work. It lasted 11 days. I mostly used it for notes, quickly checked website couple of times a day and read emails. I have played a game once for 20 minutes and another 20-30min were spent on Plex and Google Music. Screen was on for 4h13m. Wifi on for 16H.
Here is what I figured from that test:
Runtime: 10D 20H = 260H
Idle: 43%. I didn't check how many hours it said it was on idle. But let's say 250H. 43%/250H= 0.172% per hour (standby). That's 4.128% per day. That's very consistent with my observation. So, if you run Flyer for 10 days, you will spend 41% just to have it on standby. It will die in about 24 days, even if you didn't use it at all.
Screen-on (Auto brightness): 4h 13m = 4.22H. In 260H it ate 40% battery. 40%/4.22H = 9.479% per hour. So in theory (haven't tested this), you can get around 9-10 hours reading books(?).
Watching movie also puts load on the cpu and power goes to deliver sound, so I would say you will be using around 12-15% per hour. Probably around 20% per hour while streaming. A lot depends on sound level and video material. Also choice on the player and codecs used might make a bit of a difference.
I get about 4 hours of video or 7-8 hours of internet browsing / kindle reading.
a little bit comparism

agree with mcord,
it would be better instead of comparing randomly to mention :
Device Type : Flyer WiFi, Flyer 3G or Evo View
ROM : custom/ stock ROM + Kernel Info + CPUSet
Customization : or tweak or additional widget (Juice Defender, Better Battery Safer)
then the usage of application and hours spent, something like this.

I had around over 7 hours after i switch to the airplane mode in the last 7% battery left, with similar usage.
Hope this helps for utilize the battery lifespan.
I have a brand new Flyer 3G and I get about 4 hours of mixed use out of it (Airplanemode with wifi enabled, lowest brightness, 70% browsing, 30% video). I'm running stock HC 3.55.405.1 with root. No OC or custom kernel. Do I have a faulty battery? Seem like most of you get better battery life. 70% of the battery is used by the display according to battery stats. Is this normal?

If you are using it for 4-5 hours straight, then yeah that is probably normal. You might also need your battery calibrated if that is your first time. It learns and configures itself a few times after you charge it.

If people are reporting 5-7 hours display on time, and you're getting 4 hours with 30% video, then no, I wouldn't say that that's unusual.
This is tragic. Such a great tab with such a big flaw. The iPad 2 has a 7000mAh battery and the screen area is twice as big, not to mention a much more powerful soc, and you get about ten hours use no matter what you're using it for.
Gotta be a bit more fair in your comparison. That was like comparing a house cat to a bobcat.
In all 7" tablets (including non-androids), I feel that right now the contender is the the express/flyer is the only one that reigns on top for the past year, and can't be beat for only ~$250 in today's market. The only thing the A100's have going for it are the AOSP experience, the Xoom is a direct competitor.
But if you want to compare battery life, the tf101 and prime as well as A5/A6's got this beat by a mile. Not to mention higher resolutions. Point is, these are arguments extraneous of a 7"incher tab.

Yeah, I guess I was a bit unfair. I'm just a bit disappointed.. Expected a little more juice from the battery. Anyway, for 2500NOK(about 450$) it's not a bad deal. Btw the pen is included in Norway(and other European countries, I think). And the pen is the reason I got the flyer. It's almost as good as using a Wacom board for drawing. I just hope HTC doesn't abandon the flyer or have done so already. It would be nice with ICS.

I knew I forgot something!
Rooted View, Gingerbread, GoLauncherEX. I disable the cell radio on each boot.
-About 33% screen brightness
-WiFi on
-Sync on
-Cell radio off
-Bluetooth off
-Location off
My View gets unplugged from the charger each morning, rides ~12 miles to work through non-WiFi country, sits on my desk at work and gets used maybe 60 min total at work, then goes home with me and gets occasional to moderate use browsing and reading mostly. By the time I go to bed and plug it in around midnight I am usually at about 20% battery. Less if I've been gaming a lot or watching video.
So all together my View is on battery for about 16 hours a day but only used 3 or 4.
I went on an overnight trip a few weeks ago and by turning WiFi off when I was on the road the View maintained battery life well.
Hello,
I'm an happy X10 owner since November 2010. Since then my phone has been intensively used. Hundreds of ROM changes, daily use. It has been charged everyday.Now I'm on Donout HD2, with unlocked bootloader without overclocking. After all this time the battery life gone crazy. For e.g. I'm not able to watch one movie because after one hour the battery is almost empty (on lowest brightness). I remember that ~1/2 Year ago I was able to watch a whole movie and the battery was more than 60% left (I'm using MX Player). It's weird, specially because my brother uses the same video player and his battery usage is below 10% after whole movie(SGS II). There is also weird thing that the phone is doing> After I use it intensively and turn off the screen and leave it for some time the battry gets loaded (+ 1-15%). The problem exists only when I have screen turned on (battery gets very warm). Today I've watched Youtube for ~15min (using WIFI) and I had to stop it, because the battery got from 45% to 15%. Of course I have some programs running in the background (musicXmatch,ProximityScreenOff,Program TV,Profile Settings, Equalizer, Flip and Sleep, Clipper, Missed Reminder, KeepScreen, Callrecorder, Setxperia, BlingBoard, Thumb Keyboard + system processes).
So my question is:
-Is the ROM wrong (I don't think so)
-Some of the processes need more energy
-Is the battery old and I should replace it with a new one (That's what I'm thinking of)
Please share Your experience & suggestions.
Hi,
how many empty RAM do you have when phone boots up?
Also try installing CPUspy and run it for a day, an you will show how is phone under pressure. Also install CPUMaster, maybe changing CPU governor will help.
Main power comsumption is form CPU and display. I also have set it on one of the lowest levels, because of durability.
I had tried about ten different ROMs (dont count many versions of each one); but in most of them I observed little bigger power consumption then on my current. I chose Wolfbreak gaming and cleaned junk apps (more then he did ) and got great battery performance - about 2 - 3 days with standart usage, 1,5 day with high pressure.
"Problem" is caused only when screen is on because CPU is awake, but when screen off CPU automatically goes into deep sleep mode with tiny consumption
But in you case, install CPUspy, report it here and try to cut off some junk apps - there are a lot of them in any rom...

Same here mate. My phone is even older than yours. I got mine in June 2010 - so nearly 2 years old. I didnt change ROM's till 3 months back (only changed 3-4 times till now, am on X10S now). Dont use phone for anything other than calls, chatting on gtalk, whatsapp etc. That too not too much. But yes, battery has deteriorated like crazy. *Battery loses 1% for every minute screen is on*. mind you, this is on 40% brightness with auto brightness turned off. Only data connection on, bluetooth, wifi, gps turned off.
I wouldnt say i have really used my phone a lot. So battery deterioration is really weird. I have always had a doubt about the FPS Uncap, that it causes the screen to draw lot more power than when FPS was capped (i am assuming the FPS at 55 is achieved at a higher refresh rate than when FPS was capped at 30). I couldnt find any script to turn the FPS cap back on so that i could test this. so cant say for sure.
battery does the "back from the dead" trick on me too. Playing a game like PES, Fifa etc., sometimes phone dies when battery was still 22-23%. Then restart the phone and it stays on for 2 odd hours. Start game again, and it dies within minutes again. Once it went to 0% while playing a game. I tried to switch it on, it did.. and i left it as it is... after 30 minutes, i check the phone, battery has crawled back to 31%!! and then it stays on for nearly 4 hours after that.
Basically, the battery can go on for 1 day or slightly more on standby... but if u use the phone (duh!), its kaput.

Your battery seems to have other problem - needs to be recalibrated. In worse it needs to be replaced.
But firstly try things I have described above for jakuburban, it might help also.
Good luck!

Yes, I'll try all of them. I've set the CPU usage to ondemand (like I always had) and noticed one thing.
Whenever the screen gets on the CPU freq. gets to maximum (only when screen was on, doing nothing)

"lightbox_next": "Next",

"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
And only after I turn off the screen it looks like that
That means that the CPU freq. is Maximum or minimum, nothing between that (rarely).
I'll provide more snapshots after longer usage
to jakuburban:
Wow, he we got it! Phone is on max frequency as possible all the time!
Also I cant see the deep sleep - could you test this:
- open CPUspy, tap form menu Reset timers
- use some task killer, kill all the application
- turn off the phone (not shutdown, only to disable screen) and leave it for few minutes
- after that turn on the phone and look into CPUspy if deep sleep was active. If not, we have second problem.
To fix it, do you have unlocked bootloader or you have custom kernel with standart bypass method?
BTW.: Wow, I am now the senior member ! I am getting older faster, than I thought

So here is Your answer. I've changed my kernel to DooMLorD and everything works better
Nice to sse that it is solved
Also recommend to change CPU governor to "interactive" - its the best between almost nolags in eg. movies and apps and wit acceptable battery consumption. But not sure if it is includedin this doomkernel,so simply look into CpuMaster and give a try
"ondemand" governor has more battery drain in most roms.

Just have a look at the below videos. Unfortunately, that's how the batterylife & performance of the Exynos version is, just like mine. Unless you tweak it with so many tweaks and workarounds(search the forum, there are many tweaks if you like to consider) like many others here, there isn't much hope unless Samsung seriously considers resolving this which is unlikely.
Yes it is correct the battery life on this s9plus is pathetic,
Even on my phone the android system is taking major amount of battery ,
I tried factory resetting my phone a few times but no luck .
Waitng for an update from samsung

In a statement, Samsung indirectly said that "the bad battery life is a non-issue", so an update isn't coming soon...

There is definitely a lot of bloatware running in the background though, have you tried running KillApps?

Your Android System is particularly high at 21% compared to your SOT.
Noticed that you're on 3G, it consumes battery a lot more compared to 4G.
How's the mobile coverage at your area?
The exynos version of this phone sucks big time, I can tell the battery life is horrible Max 5 hrs SOT. I have switched to xz2 xperia and it beats Samsung hands down in every department. Batteries are amazing.

There won't be any update from Samsung for sure. I sold this terrible phone. Samsung software optimization is very poor. On my xz2 I don't do any software tweaks.

my cpu frequency is stuck at 1.79 and this is why my phone is lagging and heating and draining battery .
is there any way to check what is spiking the cpu so much ?
i checked in cpu process app and it says system server is taking the cpu .
any technical person who could help .

I thought LTE consumed more battery than 3G... The reason was a problem with the network. Fixed now so I'm back on 4G. Lets see if it makes a difference
Well love the phone but the battery is the worst I've seen so far for the price u pay. People focus o SOT time but I do the same as on my old iPhone 7 plus but with the iPhone would last from awake to bed time with one charge S9 plus 2 times at least and with though about running out all the time. Shame brilliant phone.
I'm having great battery life on my Exynos 9+. See the attached screenshot.
Only disabled Bixby and AOD.
I use Facebook, Messenger, Snapchat, WhatsApp, GPS high accuracy and sync one Gmail and one IMAP.
For testing purpose I decided to run the whole day with medium battery saver activated, but modified to only restrict the CPU and lower the brightness a bit. That means still running max. resolution and syncing in the background.
Right now the phone still has 36% battery left with:
- 18 hours 33 minutes since unplugged
- 6 hour 30 minutes SOT (That is potentially 10 hours SOT with 24 hours since unplugged!)
- 10 minutes phone call.
Besides my regular usage pattern, I've also played a game a lot on this charge.
No complaints here yet, im getting 5hrs SOT and have only done a few charge cycles so i expect that to improve.
Im getting close to what i do on my pixel 2 xl so in my eyes thats impressive

I had an Exynos S8+, and battery life on that was pretty bad, with Android System also taking up more juice than the Screen. Now I'm on a Snapdragon S9+, and dare I say battery life has almost doubled. Android System battery usage is way below Screen battery usage.
Two steps which fixed the battery drain for me :
1. Changing the Location Settings from "High Accuracy" to "Battery Saving" {You can find this in Settings -> Connections -> Location}
2. Using 2.4Ghz WiFi instead of 5Ghz WiFi channel. My Router is a Dual Band Router and somehow when I connect to the 5Ghz Channel, the battery drain is almost doubled. Sticking to the 2.4Ghz Channel improves the standby time by quite a lot.
Hope this helps.

It's router specific. It only matters if you have a DualBand Router and you opted to connect to the 5Ghz Band.
It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note 10+ before depleting the battery.
Then, drop a comment if you have anything to add!

This was my first day after battery learning usage patterns went away. This was actually like day 4 or 5 of owning the phone.
Not bad I'd say...
Here's a screenshot of my screen on time. I used to phone pretty happy today but this is my best so far. Yesterday the phone died at around nine and a half hours fuse lately I've been loving the consistency of the battery life on this phone. It's similar to the s10 plus in the fact that the more you use it the longer it lasts. Thankfully I've had zero issues with battery drain to my knowledge.
this is on a day off with all the Bluetooth tracking nonsense turned off,
Location on during the use of one specific app for about an hour and a bit,
Optimized setting on battery,
Sync on for Gmail, ig, etc
Wi-Fi turned on all day,
no always on display,
no adaptive brightness,
What are your thoughts if anyone has questions please let me know?
(Edit phone is at 1 percent with 10h and 12min)

Snapdragon is better than Exynos so it will be a better performer

Here's a list
Sad
Terrible
Note 10+, adaptive brightness, dark mode, medium power saving mode on
Great reception and signal. Weak results.
Maybe a rogue app you got there. Check for any app crashes.
I'm not getting good battery life...
With brightness below 50%, max resolution, always on display... I have the exynos version.

Me too... battery sucks on my exynos, brightness 35%
Why??? 5h without game or video
Haven't really formally tested all the way to zero, but today at 80% I had about 2 hours of screen time. Now I'm at 63% with nearly 3 hours of screen time. So I'm thinking 6-7 hours of screen time with my daily usage, which is excellent for me.
Performance mode on, FYI. Brightness usually 50%+.
