Can a dev please make a patch implementing this app/script/hack. The Inc has a red theme so I may be willing to go with a red display if it truly doubles battery time. I read something about adding an option to the developer app. Being able to turn it on and off would be ideal.
Thank you all in advance,

I would also be interested in something like this, if it can give me longer battery life.
Ehh if youre really desperate for battery life why not just do the recalibration trick? I'd rather have the battery run out quicker then have the phone look like that anyway.
The thing i don't get about this is they claim it can give your phone double your battery. Wouldn't the only thing this effect is the draw from the screen? I mean we already went from the lcd screens to the amoled screens and they are supposed to use alot less power and i haven't noticed any difference. My screen is only like 5% of my battery draw also....

this is correct. it won't make our batteries last twice as long, but it may reduce the power used by the display by about half. our display is not a battery hog to begin with. AMOLED is more power efficient than lcd 3/4's of the time. the only time AMOLED draws more power is on an all white or mostly white screen. this is why the web browser appears to kill the battery so fast.

I think that's a reporting bug with the stock Incredible ROM, because screen shots from a Nexus One show the screen being far and away the largest power draw. Flashing my Incredible to CyanogenMod also showed the screen as a large power draw (75% or higher). I didn't notice any appreciable difference in battery life either.

I had similar results using the yeti rom. Display was always in the fifties or higher.

I'd rather not use my phone at all if I had to use it with that red tint. I understand someone using this to test but why would you want to use this all the time? If you need more battery, go buy a new one. Turning this on defeats the whole purpose of having such a nice phone and screen. It's like buying a V8 and disabling 4 cylinders to save gas.

I can see how it would be useful to toggle on in certain situations (emergencies, etc). The amber tint didn't seem quite as hard to look at as the red did.

Yeah, I'm quite sure that number/percentage is a weighted average. That's why "cell standby" appears so high, I think each one of those categories could be duty cycle or total percentage of potential power drain, such as 65ma/120ma= 55%, although it's obvious that the display will be one of the major drains -- it's always "on" unless the screen is fully asleep or the phone is off--let's not forget the backlight, which is totally independent of pixel intensity/color's specific power draw.
I'd like this as well, if only because the lowest brightness is pretty bright to my eyes in complete darkness!
I am really interested in seeing this on the incredible.
I am an amateur astronomer, and the night vision mode would be really nice to have.
We may have AMOLED screens but soon there will be a ton a people with LCD screens... remember the switch because of the screen shortage?
Granted I probably wouldn't use it much... it'd be more of a novelty for me.

Hello all,
I've been suspicious of the power draw of the screen on the GNex, and so decided to figure out how much a difference brightness made.
This is to test the difference extreme brightness settings make to battery run times. Including text, browsing or having radios on will dilute the results. I'm only interested in the efficiency of the screen and its supporting infrastructure people!
Here's my testing method.
1. Charge phone to 100% using a PCs USB charging (should give a more full charge than the wall adapters quick charge, I think, otherwise no harm done). Leave attached to USB cable
2. Switch the phone into Airplane mode.
3. Switch off Auto Brightness and turn brightness to Max
4. Restart Phone. Leave it to settle for a few mins
5. Fire up "Just Pictures" and the image "TotalWhite.jpg" (attached). No other photos in the folder where it sits.
6. Disconnect USB charging
7. Start Slide show. Record the start time.
8. Every now and then (about 45 mins to an hour and bit) I quickly pop into settings and take a sneak look at charge level - don't want to get caught out!
9. Resume Slide Show.
10. Wait until the phone switches off, which is less than 2% charge
Now, it's not a quick process as I'm going from 100% Batt until auto shut off. So I'll be updating this post in installments. Today is the Max Daddy Full Brightness White image!
Full Brightness, White Image:
100% 00h00m
85% 00h39m
60% 01h53m
35% 03h08m
0% 05h00m
Pretty good I think!
Battery status stated that Screen was 91% and Android System was 9%. Screen on time was the same as the run time. It never went off.
There's a heavy set of disclaimers to go with this though: The White Image isn't quite the right aspect for it to display across the full amount. Check out the image "White Full The Phone.jpg" - it's pretty close though. Just Pictures isn't so full screen that it takes over the Android buttons - Anyone know a 100% full screen picture view BTW? Between the point where it comes up with "Please connect your charger" (15%) and 6% it said that message over the White image and partly dimmed the screen - I'm at work and was in the middle of something when it happened.
Minimum Brightness, Black Image:
100% 00h00m
85% 01h26m
82% 02h05m
18% 08h54m
0% 10h47m
Battery status stated that Screen was 85% and Android System was 16%. Yes, that's 101%, but there you go... Screen on time was within a minute of the run time.
Again, some notes on the testing: From the "connect your charger" point (i think 15%) to 8 % it had the message on the screen. Just before the end I accidently touched the screen and ended the slide show for up to 15 minutes and the screen went off. Switched it back on and it was at 2%. It then lasted something like 30 mins before auto shutdown. Black isn't Black! check out my the photo "Black Dim The Phone.jpg" - ignore the strange black specs, it was 1 seconds exposure at F1.4, with the camera facing down - think there's some crap in my camera body/lens.
Minimum Brightness, White Image:
100% 00h00m
0% 10h20m
Again, Battery status stated that Screen was 85% and Android System was 16%. That's the same as when I ran it on Min Brightness, Black Image...
Maximum Brightness, Black Image:
100% 00h00m
0% 10h52m
Battery status stated that Screen was 90% and Android System was 11% (again 101% also probably due to some rounding going on). Screen was on 100% of the time, Android OS was awake for 100% of the time, CPU time 23 Seconds
Overview:
Maximum Brightness White Image: 5h00m
Maximum Brightness Black Image: 10h52m
Minimum Brightness White Image: 10h20m
Minimum Brightness Black Image: 10h47m
Well, well, what's happened here? Maximum brightness with a black image scored the longest run time - unbelievable, right? Yeah pretty much: On the minimum brightness black run I did check the battery stats a few times. The black image run had a greater Android OS drain (11% vs 9%) compared to the white image. As I switch the phone off in preparation for the test it's possible I inadvertantly bump charged the phone. In addition to this, I was trusting the phone a lot more in this, the final test and didn't check the battery status near the end, so perhaps drawing a lower current happily sitting there doing nothing other than displaying a blank image the phone managed to syphon off the last dregs of power, as opposed to spending CPU time with me rummaging through the settings screens for battery stats. Let's put it all down to being in the margin of error and consider the Black images to have the same run times, despite the Android buttons blazing away on Bright (but they aren't many pixels).
Conclusion:
Back to my original concern, that the screen was abusing the battery more than necessary. I'm mostly happy with the outcome - Black bright and dim screens draw substantially less than a very bright white screen on this phone, as it should. It's surprising to see that on dimmest setting the white screen got so close to the run time of the black screens. It's producing a lot more light than either black screen. It's drawing c5% more power than the black screens, but I would expect a lot more. I'm guessing that the circuitry to run the Screen and the small amount of power used to make the "Black" OLEDs glow dark dark grey draws only a little less than the white screen.
And that's a shame. I wanted to run an app such as "Off-Clock" to have a clock on the screen like the Nokia N8 used to do, but i'm thinking this will eat the battery in 10 hours 20 minutes. Only one way to know for sure....
My initial annoyance that Black never is actually Black whilst the screen has faded. Many of you good folks have pointed out (and after more Googling) that all OLED screens have this, although the reason for it isn't clear. It's either to ease the transition from black to lit by having the LED at the threshold already, power seeping into the circuit somewhere or something else. Who knows, maybe we'd get better run times if the screen was on full brightness but used PWM or a fast strobe to show a dimmer image!
That's all folks, discuss, and remember - continue testing...
I love you for doing this. Please don't stop.
Some tidbits: The whole phone was warm, front and back. Not scary hot, but like a nice hand warmer. The screen shots were actually done after I connected the charger and restarted the phone. You'll see the graph shows it starting to charge, but all the stats are for when it was last on the battery - in the test.
Thanks for testing this.
How do you define min brightness?
The black color, do you mean #000000 hex color code?
That will last days!

Not too scientifically - I made it black in MS Paint. It's a JPG. I tried it out in portrait and landscape on full brightness and I can't see the edges of anything on the screen, so it's as black as the rest of the black in Gallery. If you have a better way, then I'd gladly take a 16x10 black image if you think it is more black.
Min brightness will be using the brightness slider in settings. I haven't rooted the phone so don't see any way to get it lower. I tried the app "Dimmer" but it's the same brightness as far as I can tell as min setting. Also I figured the min setting was relevant to more users than something they can't easily get to (or probably see on screen!).
Do you have any suggestions? I want to root, but my home PC can't see my GNex. It's being a pig about it and I haven't got Broadband ATM... Hope to root as soon as I can.
Just a quick input. If you just show a picture for 5h how does the cpu perfom in this time? Isn't it really bored?
In addition if you switch it to air plane mode it doesn't use any power for transmitting a signal. I know this point is really tricky due to the fact that not everybody receives the same signal strength.
Isn't there a more realistic way to test it? Like a combination of stability test and the white picture?
Or a slide show with specific pictures, for example a picture with lots of green, one with a lot of red, one with blue, one with white and one with black?
I really like the idea but if we could create something like a standard which tries to simulate real usage that would be great for future testings.
So that we could say something like:
Galaxy Nexus with Vanilla Android -> 5h with XDA battery benchmark
Galaxy Nexus with CyanogenMod 9 -> 5.3h with XDA battery benchmark
We could compare different settings and see how good they perform based on a "standardized" procedure.
Hmm is this probably a bit too much?
I like the idea of a standardized battery procedure for XDA.
Only thing is, i feel like just web browsing would give a better idea, mostly white website sites and it uses data and CPU/GPU still to give real world usage results.

Hi Nebucatnetzer, I get what you're going for and think it would be a great test. My original goal was just to see how much of a drain the screen was. I used it on Airplane mode as I do not want to have any other drains diluting the result. As you say, signal strength changes, and so this becomes an uncontrollable variable. I'm only showing a white image as it's the most uniform full power test of the screen I can think of. As the display is RGBG, maybe a greenish white would draw more, but I can live without that - web pages are predominantly Plain White and Text in ICS is white.
I actually think that 9%/10% drain for Android OS may be a bit high for 5 hours. I think Just Pictures may be the cause for it as it does every minute change the image in a slide show... to itself...

It was one of the things which annoyed me the most here. Everyone says he has the ultimate tweak to save juice but you never really could measure it.
We probably have to skip the data part due to asimilar signal strengths.
And it would be really cool if we could find something which works for every phone.

Hi! I'm not trying to do a real world test as such. I'm trying to find out how much of an impact a white screen has compared to a black screen. I have a suspicion that the Black screen will draw more than it should do. I've been using my phone on Auto Brightness and at night, min brightness and have found the screen is caning the battery. There's more to the screen than the AMOLED - there's also a MIPI Framebuffer controller, plus whatever interfaces that has to the rest of the phone.
I'm aware that ICS and the other internals of this phone seem quite efficient, so any savings I can make on the screen (which really does suck the juice) should translate into big run time gains... Surely...Right?
If it turns out that there's very little different in battery life between a Black screen and a white screen, then I'll crank up the brightness to revel in its retina destroying beauty. If there is a difference, then i'll stick with my black homescreen background....
The black screen shouldn't draw any power virtually as long as its truly black. SAMOLED functions where black doesn't turn the pixel on so no energy is used. I think the black test has been done by someone, you can probably google it.
We we aren't criticizing you specific we just hijacked the thread a bit sorry for that .

would be good if someone could make a benchmarking program which pumps out signals in a set pattern on all devices at set frequencies and at a few different power levels. It would't need to wait for a response from any cells or WiFi routers, just talk to itself and only itself. Maybe this would need too low level access to work, below root.
Then you'd have your predictable Radio part of the test. If it's even possible.

Well, I hope a black screen will draw considerably less. We shall see. Or it will be a revelation... Or everyone will get to witness me finding out that my phone is defective. Hahaha... oh...god I hope not...
I may run the black test overnight. It should last the night. If it doesn't I can always hook it up and check the last "On Battery" status as I did earlier. Then I can run two tests tomorrow!

This sounds more than difficult. Not a clue how one could do this.
As soon as I have my device I'll probably start a thread where we can think about a standardized (what a stupid word) battery test.
Curios how your second test goes.
Instead of the black screen test, amoled screen, you could do a white background with black text. This would give better overall real world stats.
Text generator http://www.lipsum.com/feed/html
Second test - black on lowest brightness - is underway.
Some bad news, which you may already know about: Black isn't black. It's very dark, but the phone isnt switching all the pixels off. I took a photo with my SLR in the dark but can't upload at the moment, will upload tomorrow.
Just took a sneaky look at the stats.
85% 01h26
The draw is 85% screen and 16% Android OS. Yeah, I know they don't add up, but that's what it says.
So far, the draw is higher than I expected for lowest settings with a black image. Odd. The phone isn't warm though, like when the screen was showing a white, max brightness image. It's cold.
Sure hope it doesn't start moaning about running flat whilst i'm asleep...
Last check before I go to sleep: 82% 02h05
Same split of 85% screen and 16% Android OS. Who says percentages have to add up to 100?

Hello,
I've been using this device for about 5 months now and the battery life for me has been great so far, but there's so much you can do when you need the juice in your battery last longer. In order to help those who want to get the best battery life out of their phone, I've compiled a list of things I do to make my phone last longer.
We'll go from the things most effective to the least and mind you, all of these can be done without rooting of using ADB etc. So let's start
'''Turn on Gray Scale'''
As we have an AMOLED screen, turning on grey scale will give you an improvement in battery life of around 25-35 %, and it's especially noticable if you use your phone in high brightness mode.
'''Dark theme'''
Dark theme obviously saves battery on our phone, there's and awesome guide on XDA guiding you to do it without rooting or using any theme engine.
'''Set brightness to 50%'''
Our eyes don't perceive brightness linearly, so 100% brightness will take around 50-70% percent more battery than 50%, but going much lower won't help either cause increasing brightness from 0-50% results in around 20-30% extra power draw.
'''Restrict background running of less used apps'''
You can restrict an app from running in the background and this setting is baked right into the App Info settings,
Go to app info and tap on battery usage, from there, restrict the app.
'''Enable data saver'''
This can be enabled via Quick Settings menu and this can drastically save battery if you're mostly on Mobile data.
'''Turn off Auto Sync'''
It is long known that doing this can save a bit of battery.
'''Enable Battery Saver'''
Pretty self explanatory.
'''Change minimum width'''
Set minimum width to anything less than 400, this leads to less information being displayed on screen which results in lower usage of GPU, and thus better battery (somewhat)
'''Reduce animation duration scale'''
This will speed up everything and improve battery life just a bit.
And that's it from me, if I remember anything else, I'll make sure to add it, and please make sure to tell me anything that works for you, I'll happily add it.
If you want to get absolutely the best battery life out of your device, you must install a custom kernel. I'm using Fenix currently.
Also, turn off printing service. This idiotic thing is turned on by default. It keeps sucking battery for no reason at all. I'm not using stock ROM now but you can find it by going to: Settings>Bluetooth & Devices (or something similar)
Can you post the link of the thread for enabling dark mode I would like to try that.
Another tip - switch to airplane mode, mobile network is one of the biggest battery consumer..
But seriously, how does greyscale mode save the battery? Instead of glowing one of the subpixels for displaying a color, all of them must be shining to provide different shades of white color. It might even use more power.
Width change and animation duration scale have some very interesting thinking behind them, it will have absolutely no impact on the battery.
Dudes, just enjoy and use the phone. Why do you want to cripple your experience just to gain extra few percents of battery per day? If you're living of the grid, there are much better phones for such a lifestyle.

There's an XDA article comparing battery saving with AMOLED on black and grey theme, you might want to check it out, or you can also watch a video by Mrwhosetheboss to see how it went for him. As for animation speed and DPI, they have the least effect on battery life as I've stated above. Kindly do some research before you start making claims.

Where exactly in the article does it say that monochrome display saves power over colored one? Actually it's you who started with unique claims, so please provide some proof.
I got S22 Snapdragon Variant but the battery still sucks and phone heats up much after I have done the following.
1. Followed [GUIDE] [NO-ROOT] Complete Samsung OneUI Optimization
- Most settings applied
- Phone set up without Smart Switch
- Adaptive Battery disabled
2. Installed [App]Galaxy Max Hz (Refresh Rate Mods, Screen-off Mods, QS Tiles, Tasker Support and More)
- Adaptive Refresh on Power-Saving mode On
- Adaptive Min 10Hz, and Max 120Hz
- Force Lowest Hz on screen-off (10Hz)
2. Installed ®FDE.AI - Ultimate Android Optimizer
- Power-Saving mode
- Force Doze Mode On
- Sensors Off on screen off
- Analyze Apps on screen off
3. S22 Settings
- Sync disabled
- Always-On Display - Tap to show
- NFC, Location, off when not in use
- Power Saving mode 24/7
I am seriously tempted to get a Pixel 5 instead, which I am willing to sacrifice the performance + 120Hz because I'm just another daily user.
Is there a way to underclock Snapdragon 8 Gen 1?
Let us hear your thoughts too. Thanks.
Which s22 model do you have?
Also I felt like I got more battery drain with adaptive battery off so I kept it on but slept all apps except ones i need notifications for
I have the 901e and updated to the Vietnamese firmware avdf running very similar set up to you getting 7 - 9h sot
Try removing that optimiser and using the doze setting in galaxy max hz
Also 96hz works with power saving on
Get galaxy app booster it's with in good guardians (can just download the apks online if you can't find it in the galaxy store) from what I've read it wipes dalvik cache
I'm on S22 SM-910E/DS.
I see... I'll give it a try on your suggestions!
But do you still face quite abit of heat during screen on and using of phone after the tweaks?

No heat at all, also in battery powersave settings you can limit the CPU to 70% (in case you didn't know already) from what I can see in adb it's on even when powersaving isnt
Mine is an SM-S9010. I rooted it and did some work on it. I turned off cores, underclocked it, turned off adaptive battery and so on. With all the things I tried, the SOT differs from charge to charge. I stopped even gaming altogether on it. I managed to get 30 more minutes out of it.
So the average SOT for me sits at 4h. I've got the Prime core and the last Middle core turned off, the Little cores underclocked to 1.5GHz and the rest to 1.9. The phone still overheats but the drain is slightly better.
Then there's the idle drain. The main culprit is Google's notorious Play Services crap with its services framework and all the other Google BS. I even installed a module to let it be optimized/dozed. It worked half the time. The other half the drain was even higher than before so it did worse than good. Now I've got Battery Guru installed and this thing monitors everything I need, plus it has a lot of stuff embedded in it, like the Quick Doze mod, power saver and Sensors Off with the screen off, etc. I've got the Powersaver on after the screen turns off and Data saver, and the idle drain sits at ~1%/hour. It goes at 0.7-1%/h, during the night unless the Play Services start spasming again, and they tend to do that a lot. And before having someone suggest a fix, please don't. I tried them all. They're just temporary solving the issue.
So yeah, there's no way in HELL someone can convince me they get 7-9h SOT cause that's just silly and exaggerated lying for a reason I don't understand.
In a 20h time frame the battery will lose 30% while the phone is idling. That includes ~10% which goes to some music listening and calls. I'm then left with 70%. After cutting off the 10-15% at which I plug in the phone, I'm left with ~60% of actual battery for the SOT. That means ~2150mAh. The battery is simply too small to be capable of anything more.
If you watch hours of YouTube, yeah, the SOT will turn out better because you're barely touching the screen once in a while and the CPU does the bare minimum and nothing overheats or goes into seizure mode. And the longer you use it in a smaller time frame, the better the results. When you use it over a longer period of time, go from idle to active use, idle again, and so on, that's when things start to take shape, so to speak. Then the moment you start scrolling and loading and loading things on Reddit or TikTok for example, or you browse the web, switch between apps and so on, things also change. The CPU will jump from a range of frequencies and produce more heat. The battery will share some of that heat and thing will get hot relatively hot soon, especially if it's hot outside. That translates into even poorer battery performance cause the hotter it gets, the worse the active drain is. And also, the lower the percentage, the worse the drain is too, I have noticed since I got this piece of crap phone. But yeah, if outside it's hot AF, the phone will be hot too. Today here where I live it's 30C right now. Using this thing and doing nothing intensive on it still gets it hot. It's too small to dissipate heat properly. Those saying "not heat here" etc, it's not possible unless you live in a slightly colder climate.
Not to forget to mention, I debloated this thing, removing pretty much everything Samsung included and I left only their bare minimum BS. Did it solve anything? Yes and no. It's a small difference but definitely not as big as I was expecting. It mainly reduces the idle drain, but like I said, the difference is extremely minimal.
I used a Pixel 5 last year. It was a great little phone. The battery life was fantastic on that thing. It was basically the first phone I've ever had with such a great battery life. The I moved to an iPhone 13 Pro. The one was even better. I never had to worry about running out of battery. Then after getting bored with iOS, I preordered an S22. Did I even consider the battery life? Absolutely not.
In conclusion, if you keep trying to find a solution to the problem, you won't fix much. Thing might improve today but tomorrow you'll be disappointed again the cycle starts again the next day.
The 8 Gen 1 built on Samsung's 4nm architecture is absolutely rubbish. It's terrible in terms of efficiency and when you pair it with a tiny battery you get a Galaxy S22, the devil child sent on Earth to destroy your mental health.
So don't bother trying much. Just use the phone as is try to use it as is. Just have a power bank with you when you're away and you're fine. Otherwise you won't enjoy the phone one bit. I, for instance, got to a point where I took it out of the case and now I use it with just a screen protector and the rest completely unprotected. If I drop it and it gets smashed into a million pieces, I don't care. Cause this is the worst phone I've ever had In my life. It's hard to like.

Mine is an SM-S9010. I rooted it and did some work on it. I turned off cores, underclocked it, turned off adaptive battery and so on. With all the things I tried, the SOT differs from charge to charge. I stopped even gaming altogether on it. I managed to get 30 more minutes out of it.
So the average SOT for me sits at 4h. I've got the Prime core and the last Middle core turned off, the Little cores underclocked to 1.5GHz and the rest to 1.9. The phone still overheats but the drain is slightly better.
Then there's the idle drain. The main culprit is Google's notorious Play Services crap with its services framework and all the other Google BS. I even installed a module to let it be optimized/dozed. It worked half the time. The other half the drain was even higher than before so it did worse than good. Now I've got Battery Guru installed and this thing monitors everything I need, plus it has a lot of stuff embedded in it, like the Quick Doze mod, power saver and Sensors Off with the screen off, etc. I've got the Powersaver on after the screen turns off and Data saver, and the idle drain sits at ~1%/hour. It goes at 0.7-1%/h, during the night unless the Play Services start spasming again, and they tend to do that a lot. And before having someone suggest a fix, please don't. I tried them all. They're just temporary solving the issue.
So yeah, there's no way in HELL someone can convince me they get 7-9h SOT cause that's just silly and exaggerated lying for a reason I don't understand.
In a 20h time frame the battery will lose 30% while the phone is idling. That includes ~10% which goes to some music listening and calls. I'm then left with 70%. After cutting off the 10-15% at which I plug in the phone, I'm left with ~60% of actual battery for the SOT. That means ~2150mAh. The battery is simply too small to be capable of anything more.
If you watch hours of YouTube, yeah, the SOT will turn out better because you're barely touching the screen once in a while and the CPU does the bare minimum and nothing overheats or goes into seizure mode. And the longer you use it in a smaller time frame, the better the results. When you use it over a longer period of time, go from idle to active use, idle again, and so on, that's when things start to take shape, so to speak. Then the moment you start scrolling and loading and loading things on Reddit or TikTok for example, or you browse the web, switch between apps and so on, things also change. The CPU will jump from a range of frequencies and produce more heat. The battery will share some of that heat and thing will get hot relatively hot soon, especially if it's hot outside.

Sorry to disappoint but I'm not being silly nor lying, I have absolutely no reason too i have nothing to prove or anyone to impress by talking s***, I'd be here doing the same if my battery was rubbish which it was to start with. I don't get any over heating, phone drains roughly 3% over night and barely get any google services wakelocks so you can believe what you want i really dont care what you think I'll chill here happily with a mint running s22 with plenty of sot

It's fine. It's like a described it though. A continuous run of usage with with barely any stops or very short ones, will offer better stats. That's "very light" usage. Anyone complaining about battery life is doing a lot more on their phone just like me, the one who created this thread and the majority of S22 owners, with both variants of the phones.
Sorry if I offended you. You wouldn't be able to get the same SOT with our usage though, not even close, especially of you're 100% on cellular data.

Thank you for this. Probably the most honest review about S22's battery. Like you I tried everything under the sun (except the rooting and underclocking). This phone is just disappointing. I could relate to every single line as I read through your post. Weirdly, I'm just happy to know that Im not the only one feeling this way about this "flagship" device.
I'm coming from a very old OnePlus6 which STILL works perfectly fine on a custom Android with close to 4-5 hours of SOT in a full days usage. I charge it only in the night, sometimes it even makes it through the night..
I thought S22 with a higher battery (and NEW) will at least give 6 hours SOT but man was I wrong!!
So initially I used Smart Switch, and I got a terrible SOT of 1-2.
I did factory reset and manually set up the phone and I got about 3 hours of SOT.
I went through the debloating process and now I'm 3-4 hours of SOT.. Still that is so horrible for a flagship!
Its such a let down honestly! I get a flagship and paid so much money and this is such a huge issue! And I hate the font size on the notifications/panel.. it is just not proportional to the overall system font size! And not to forget, the phones takes about 1-1.5 hours to charge. Such a pain when are used to the OnePlus DashCharge which blazes through. Fast Charge on Samsung is such a shame
S22 is seeming to be a mistake. I'm considering swapping this for a Oneplus 10 Pro OR an iPhone 13! You made a similar switch? Looking for advice on fixing this brick of a phone or recommendation on alternate device.
Maybe custom ROMs or Updates in the future will make S22 better?
Edit: I too have a SM-S9010

I doubt anything will improve things the way we want. Unless we see a complete revamp of how apps use the CPU, which is a deep optimization process, that should done by Google all the way to a system level, things simply cannot improve in such a drastic way. After doing some math, a 1% idle drain or 15-20% active drain is something relatively decent because it's based on the battery inside the phone. The real capacity of the 3700mAh is actually 3590. So it's even worse than it appears. We've got to accept in the end that Samsung ****ed up this year with the smaller phone, despite the sales numbers.
Anyway, I also had a OP6 which I really liked until the software went completely 180 and disappointed me with that insane redesign which went against everything OP started with.
Anyway, back to the S22. I'm not really bothered by the charging speed. However, considering the terrible battery life, a much quicker charging speed was rudimentary to compensate for the other thing. Samsung doesn't give a **** though. So long as business gets better.
The bottom line is, and I reached to this conclusion the hard way cause I can say that I lost a lot of money in market value in the past 3 years, is that in the Android world, if you want a flagship device with very good battery life, you've got to go big. Otherwise you'll be disappointed. On iOS, you can get that with the smaller phones. Choosing the bigger phone in that situation, will get you the best battery life on the entire phone market. Android needs more mAh to compensate for sudden idle drain, services that have seizures out of the blue and the regular active drain due to poor app optimization. The bigger the battery, the more mAh for those unexpected things to eat and the less you'll have to worry about the battery life, as long as it easily gets you through the day. But if you want to keep using a smaller phone, something that actually fits in your pocket, then I'm afraid only Apple can offer you the best. iOS is in a completely different league in terms of optimization. Not to mention how perfectly smooth everything in every corner is. That is the true definition of buttery smooth no matter the action you do and no matter the app you're using. On Android frame drops/stutters are a regular and no matter the phone I used, they've always been there, despite the claims. I guess I've got more sensitive eyes. Even so, on iOS, those frame drops are so rare, that you really get a truly delightful experience 99% of the times. Not to mention that the 120Hz experience on iOS is actually smoother than the 120Hz on Android, if that makes any sense. All the polish the OS receives is very noticeable on that 120Hz panel. The way the OS works is what you need to get used to, the restrictions and so on. If you can get past that, you're good to go.
So if you want to throw away the S22, thing that I wouldn't blame you for, a 13 Pro is what I'd suggest to you, if you wanna keep using a small phone but if you want the best of the best, go with the Max brick version.
I'm personally waiting for the 14 lineup and I'm most confident I'm gonna get the 14 Pro Max. I want to never worry about battery life. For me it's 2 big compromises I have to accept: iOS and the phone size.

Well, I guess that's what I'm planning to do too. Wait for the next iPhone. Until then I'll keep charging my S22.. and who knows maybe some miracle update from samsung will fix its battery time!

Ha Ha! I don't believe in miracles. A company that decides to address the issue by creating a mod or something to replace the back glass with something else that fits a bigger battery inside. That is a miracle to me
Thing is, the more you try to optimize this phone, the worse it gets
This is also the case for the adaptive battery that samsung has put on.
Sure you'll get good sot on any phone if you're locked in an app at low brightness for few hours that just scrolls through or plays videos.
But as soon as you start auto killing running apps and do multitasking with them after that, you'll barely get 2-3 hours sot.
Best I got from the exynos version on this was about 4.5 hours SOT with all settings I need enabled and gw4 conected to it.
But the average days (phone outside on higher brightness) are way below that. Using the doze mode when screen off, fingerprint disabled when screen is off, most of the bloatware /junk apps disabled or put in deep sleeping mode. (no root). I keep my phone at 85% and recharge when Im home/office whenever possible
Iphone really naied this down since the by just freezing the active proceeses for the standby adavantage.
The cpu doesnt really have to do anything when you relaunch them.
Im quite surprised android cannot do the same in 2022
Such a shame, this would've been the perfect compact phone if the software was done right on it.
But where is the $$$ for google/samsung for tracking everything you do ?
No matter what settings you try to disable, the phone constantly scans for gps/wifi/bluetooth devices (google's gms even claims this is for covid purposes in their TOS now)
Thank you everyone for the debate above. Understand that battery differs from one another, it seems that most people probably belongs to the side where the battery is insufficient to last through the day, or barely.
I love this phone so so much, and I got the Graphite model.
I hate to say goodbye, but I'll be going back to Pixel 5, and hoping S24, or whatever, will be a more optimized S22, keeping the compact phone size.
I use a snapdragon gen 1 s22. The battery is not terrible but also not great. An SOT of 3hrs for 3 days standby is what i get with max hz app installed, power saving on, debloated, sync on for two mailboxes. I get more SOT with less standyby time( if i watch youtube videos). I think its a nice balance for a compact phone. I had the pixel 6 before this but it was too heavy and big though the battery was slightly better.

You can get a Pixel 5 in mint condition for extremely cheap. I also looked up one cause I'm really considering getting one.

Im a pixel fanboy. But recently with the bugs, poor call quality and the random battery drains i chose to move on. I hate the material you in android 12. Atleast i need an option to switch it off. I cant root as i need to use bank apps in my phone.
Here is a screen shot of my s22's battery usage for the past two days.

Yup I got one myself now. Only downside is the under display firing top speaker which makes the volume thin and muffled. Other than that, I'm very happy with the phone!
And for god-knows-what reason, Pixel 5 rocks a 4080 mAh battery. Wonder why tf S22 weighs heavier and unable to carry a bigger battery. Bells and whistles, but neglected this basic need of a phone

If im not wrong the pixel 5 is made of aluminum(sides and back) but the S22 is made of glass(back). Thats the reason for the weight difference.

That is true. But SN8Gen1 is too much to handle for a reduced battery size. I'll go to Samsung shop to see how S22+ feels in the hand, as the battery size is bigger. But for now I'll stick with Pixel 5.
