Hi,
I'm using a Canadian Galaxy S4, SGH-I337M.
Rooted, running on Liquidsmooth 4.4.4 ROM. Also has Ktoonsez kernel. It is currently undervolted+underclock a bit, and is stable (I could overclock it, but I don't. No need).
Been wondering for a long time about the operating CPU temperatures of the Galaxy S4... Never had the possibility to do testing with CPU temperatures before. I do have a LG P500 that I have overclocked a ton in the past, still work just fine, but the LG P500 is old and do not support viewing CPU temperature, so it's my first time experimenting with that.
How hot would be too hot for this phone? There are several opinions, but never figured out if I... "minimize" the risks of my actual temperatures, for some reason. My laptop CPU throttle at 85 celcius for instance. While it's a phone, it's completely different.
At night, while connected to charger, it would be pretty cool, at 25-30 degrees when I wake up;
I would say that most of the time, my CPU is running at 50 celsius, and rarely ever exceed 65-70 under normal use, or even gaming. Plus, the CPU is undervolted and a bit underclock, so I do feel like it run cooler than usual.
Quoting Meowmix from Rogers forums:
It varies on the usage of everyone else & how you handle the phone ( cases & such). Also if you are in extreme heat or having the device in direct sunlight.

So, the case does matter? I do have that Otterbox case which is pretty tight and enclose the phone pretty well, I would believe that the phone would get less.. air.. but I mean, it's just a case, didn't thought it would affect much..?
Quoting Ahmed from AndroidCentral Forums, I would say that I have a quite similar situation.
No, just when i ran AnTutu when it runs the 4 cores at the maximum frequency the temperature is between 80-91c, and at normal use while surfing the internet the temp. 45-55c and the battery reaches 38c after an hour of continuous using.

I CAN reach 80-90 celsius, but only if I really want it to happen. 38 celsius for the battery is also correct, I never exceeded 41 degrees yet, on any Android phone (I don't know the dangerous battery temps.. But when I reach 40 degrees I try to put it down as fast as possible). With benchmarks, usually at the max frequency, or testing my undervolt with Stability Test, I CAN reach 80-90 celsius, which look really high. Additionally, I would remind that I don't overclock, and the CPU is undervolted so seems a bit cooler.
So on AndroidCentral, this is the reply Ahmed got, from "CR6" user:
I had to use my temp converter to look up & convert them to Fahrenheit. 80-91c equates to 176-195 Fahrenheit and that's extremely dangerous. These temps will not only physically burn you, but will fry your phone if you continue using it at these temperatures. 45-55c equates to 113-131 degrees Fahrenheit, and that is normal under really heavy usage. Optimally, you'd like to keep it at 38-45c. You may have a defective device if you regularly see temps over 80c and I would advise checking on a replacement.

THAT dangerous? Well, I don't phisically feel the heat - I do feel it, but since I have that phone case, that doesn't hurt at all. But like I mentionned, I never reach 80 celcius or more unless doing benchmarks. Usually I never exceed 65-70. But still it left me wondering - Why does Android allow such high temperatures in first place? Isn't the system suppose to shut down at some point in case of danger, and when?
I've also experimented with thermal throttling in the Ktoonsez kernel, and the throttling values of the ROMs. Touchwiz Stock ROM with DVFS disabled, seems to throttle at 80 celsius, look decent. Liquidsmooth AOSP ROM, stock kernel, does not seem to throttle at all (Huh)! Once, and that was exceptionnal, I've reached 100 CELSIUS using Wifi, connect to a charger after like 2 hours, room temperature was very warm, was not surprised, but when I noticed I reached 100 CELSISUS, I was WOAW, I should shut down. I did reached 100 degrees again, using Stability Test at max frequency after a few minutes. Needless to say I manually stopped the test, because I had no idea how much heat the phone could handle...
So been aware of this, "Ktweaker" app, for the Ktoonsez kernel I use now, does have a thermal throttling option, but I wondering which thermal value should I enter for best "performance"? Default was 70 degrees, I set mine at 80, I've heard of people even putting 90 for the same kernel. Besides, maybe I worry about it too much, because in no way the phone should exceed 70 degrees celcius under normal use anyway, or even gaming. Only way to reach insane temperatures would be benchmarking/stress testing...
Still, first time seeing these CPU temperatures also. I've overclocked my LG P500 several times in the past, dealing sometimes with random reboot, so make stability/overheating questionnable, but the device did not supported seeing the actual CPU temp. So I don't know which temperatures would be considered normal - probably, nothing above 75-80, correct (For the Galaxy S4, actually)?

(From another thread)
I do know it can run up to about 180 before hitting critical and shutting down
Edit: its about a 75 degree ambient temp where im at.

At which point is the device supposed to shut down? Is that in the kernel or a hardware CPU trigger? Because heck, I've reached 100 degrees 2 times, I mean, how far/close was I from a shut down? I'm quite surprised.
I've also read of people complaining of S4 overheating, especially maybe after it was released - It's possible that it heats up more than other phones, but honnestly I have no idea.
Thanks for your answer =)
Going thru this exact same thing. Same temps. This is not normal. Mines just started happening one day. Idk how or exactly when

Thank you for your answer;
Used to think some temps look normal to me - Besides, since I've undervolted last week, it's stable and run cooler, maybe better battery as well. I never can exceed 70 degrees even when gaming I supose..
I can reach 80 degrees, but only when benchmarking or stability testing, so I'm not worried, but I do wonder;
I've reached 100 degrees 2 times, once while doing a stability test at 1,89 GHz for like 5 minutes (or more), I had to manually stop. And last time was long ago, watched YouTube videos in bed, like under covers ha, maybe as well connected to charger. Not even surprised I've reach such temps after a while in such conditions, under covers, just no air (Used to do it with my LG P500 too. While I never was able to see the CPU temps on this device. Even then, LG P500 still works, but guessing build quality was much better). Needless to say I was like WOAW when I've noticed 100 degrees, and just put the phone down. Probably went from 80 to 100 quickly, didn't noticed that fast. But yeah, that 100 degrees was.. almost expected under such conditions.
I just really wonder about thermal throttling. Like I've mentionned, stock Touchwiz with DVSF disabled seems to throttle at 80, while KTweaker app for a different AOSP kernel have the default temp limit set to 70. Liquidsmooth ROM, AOSP, does not seem to have a throttling point, since I've reached 100 degrees 2 times with it (Don't intend to test 100 degrees again, huh). What would be the maximum ideal temp for throttling? Maybe I think about it too much, since under normal circumstances, I never exceed 70 degrees, besides benchmarks.
Also wondered at which temp is the phone supposed to shut down... 120 degrees?! XD Because 100 seems ridiculous to me, probably is, but yeah, my laptop throttle at 85, and it's a laptop (Intel Core i3) - Can't imagine a phone going any higher without any risk.
Thanks for the feedback
I have the exynos 990 version of the S20 FE and as we all know, the 990 is a little bit of a hot mess. However it has quite a lot to give if limited correctly.I'm running One UI 3.1 on android 11. I rooted my FE with magisk and installed Franco kernel manager. The steps below will give you good battery life and performance.
Step 1: Straight up disable the M5 mongoose cores. They are Samsung's biggest undoing.
Step2 : Limit all clock speed to 2Ghz. Trust me, the IPC on the 990 is really damn good and you don't need to worry about performance loss. Forget the benchmarks, everything just works. Getting the last 2.7ghz or 2.5ghz usually requires a significant voltage bump and you mostly wont need the speed.
Step3 : The GPU is actually just fine as is. Try to set the max clock to 370mhz, which sounds ridiculously low, but the 990's GPU was made for 1440p screens, so the UI still remains smooth even at 120Hz. I played Riptide Renegade with this setting and it was very smooth as well. You can play with this number according to how much you game, I, for the most part, don't.
My hypothesis, based on my usage of about 2 months (yeah, i rooted this bad boi about a week from purchase, screw warranty, i'm gonna be alone for life :-( ) is given below >>>>>>
Thermal throttling seems to be due to the M5 cores clocking up like crazy while doing basically nothing. This is probably mostly because Samsung uses their own "energy_step" CPU governor which still needs some work. You can try changing this to schedutil ( which is basically EAS ) and see how it fares. The GPU also ends up underclocking because the GPU has a " joint " governor ( basically ramps up and down with CPU speed to some extent, not entirely sure about this, i may be completely wrong).
I have also have put a battery charge limiter in place at 90% but that doesn't really make a difference. I use my phone quite heavily and at 120Hz but still get about 18 - 20 hours of usage (not 20h screen on time!)if on FULL CHARGE
In fact if you even disable the "BIG" i.g A77 cores, and use only the four A55 "little" ones, it's still good for daily usage. Processing time on the camera takes a bit of a hit, but you can always create a custom profile for that to enable all cores for the camera app. I have my phone skinned with the AOSP-R day/night hex installer theme.
Also huge reasons for rooting :
Tasker > for some insane automation profiles i made
Naptime, Servicely > Free extra battery life
The battery charge limiter to preserve my long term battery life.
Also a GCAM update, the scan3d APKs of BSG are getting rather good. We need to get together an tune the hell out of this sensor to get it to par with the stock camera tho, especially during night. Also no telephoto support, AFAIK. One S20FE confing shall be in the works.

if you're changing the max frequency via a kernel tweaking app you can simply change it back if you don't like it.

It's been about a week and just 2 days ago I started seeing better battery life. The first 4-5 days were the same as before. I straight up disabled the 2 "prime" cores and the performance is basically the same. Never noticed a hiccup or a slow down. Before I rooted and tried this I was getting about 2.5 hrs SOT before I had to charge and now I'm getting about 3-3.5 hours, just a little more. Seems like less overheating (haven't check temps, just the feeling of it). What I haven't figured out is how to make the change on the GPU frequencies stay, if I set a max, it doesn't cares about it and it still goes above the limit. I'm always using 120 hz on this changes, so I'd say it's worth it.

I think should wait for Android 12 to see if it gets better if not then I will do this process
Me too. Great tips!
Go to settings and search for "Limit CPU speed to 70%" and turn it on. Normally gives better battery life. Haven't seen any major bottleneck in performance.

Haven't experienced any major performance hit in regular usage. Not a heavy gamer so your mileage might vary.
Guys...the last update for Exynos really worked? I've heard about changes in CPU governor that worked!

Still that§s a really poor battery performance, and now without warranty... I will take my s20fe to samsung and if they wont repair or change it, I will be also forced to root my phone.
My experience rooting S20+ Exynos 990 following this thread:
TL;DR: Added 6-8 hours of standby battery life just from turning off prime and big cores, haven't checked on screen battery life since I don't use my phone much at work, but I wanted standby time improved.
Before turning off the prime and big cores, I got 11 hours tops on battery life. Seemingly out of nowhere the phone was always warm, despite just sitting at my desk with a very strong signal. I knew that at 12 pm, with 50% brightness, 120hz, and AOD I would expect at least 50% just gone even though I barely even used the damn thing. The straw that broke me, is that even though I was connected to wifi, I could only expect maybe at most, 3-4 hours of screen on time, which finally drove me insane. I checked out the thread sometime ago but was skeptical if it really was worth the trouble since it seemed a lengthy process. Take it from someone who hasn't rooted in a long time, just follow the guides and it all is pretty simple.
After turning off the prime and big cores, immediately thermals were so much better, after 3-5 minutes the phone was much cooler, about 5-8 degrees cooler on the chip area. Since the phone was reset, I couldn't really tell if battery was better. After the using my phone for a week rooted I can tell you, the battery difference is abysmal.
Before, I was struggling to end my day on 30-20%, now I can confidently end my day on 60-50%, depending on how much I used my phone. When idle the phone, barely sips battery, my estimate is that it went from 8-10% just idling, to 3-4% (need to check since I haven't turned on the prime cores ever since rooting). I wasn't willing to sacrifice 120hz so I always kept it on and battery life was good, however I will test with Max Hz on 96 hz, which should extend battery life.
Performance on the little cores is virtually the same, I haven't noticed any hiccups, lag or anything by that matter. I was concerned that on this thread it was mentioned that the camera took a hit, but on the S20+ nothing has changed, maybe the shutter is 0.3 seconds slower but I honestly don't notice or it doesn't bother me at all. Recording high resolution videos is no problem, and nothing really changed for me. Thermals are massively improved, if you're doing a heavy task, like recording, downloading or uploading, or something that you know requires heavy lifting, of course the phone will get warm, but not even close to how hot it would get just idling or doing the same tasks with the big or prime cores.
Since I don't play games I can't really say whether gaming has taking a hit or not, I would say that it depends on the game you're playing. You can always create a profile that enables the prime and big cores on FKM.
Overall I can say this, if you have an exynos 990 phone and getting real sucky battery life, rooting is the way to go. This phone just feels so much better with this extended battery life, and now rooting allows me to mod it as I want it or turn off things that weren't useful. Just be warned you will lose Google Pay and some apps from Samsung that use Knox, but for me what you get in return is so much valuable.
Please let me know if you have other questions from rooting the chip.
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.

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.

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.

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.

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.
