[Q] Does your Galaxy Note II GT-N7100 overheat? - Galaxy Note II Q&A, Help & Troubleshooting

Just got my GT-N7100 a few days ago. I noticed that the upper part of the phone (where my ear rests when I talk) heats up rather quickly. Is this something that others have experienced? Is it normal?
My old HTC Inspire 4G would stay cool for a relatively long time.
I understand that the Note II is powerful, and I love the phone, but the heat concerns me.
Should I worry or is it common? I can still return it to the vendor.
Thanks.

Are you on stock everything?

I'm not sure I understand what you mean.
This is a brand new GT-N7100 SIM free International unit. All I did was installed some apps from Google Play and Amazon Android Market. No rooting, no ROM flushing etc.

No.
If your device overheat than something is wrong.
Go to your retailer and let it fixed.

The processor is located near the camera flash on the top side of the phone. That side will get warmer. The CPU idles at ~35C, and any use at all pops its up to 40C, which is enough to warm the phone slightly. On stock voltages heavy use will bring it above 70C, which will significantly heat the phone. So... if it is a problem or not really depends on how hot it is getting. The N2 throttles at 80C, and if you are hitting that on stock it is defective. At sustained 80c the top of the phone will get quite uncomfortably hot - but not untouchable.

Mines gets a lil warm after moderate use - like a 10-15 min call, using tapatalk for extended periods, etc.
It will get significantly warmer if I'm drawing something on SketchBook Mob, playing Mass Effect 2, or any other high rendering 3D game. But on idle, I can't say I've really felt any spike in temperature.

I have a CDMA/LTE version with a sim slot. Yeah, I know it is kinda weird, but that's how they do it in Korea. As for heat wise, it has never gotten hot. Just mildly warm.

There are lots of apps on the market/xda for this. I use Android Tuner myself. Any temp monitoring option may require root though; I haven't tried them without.
When you do find one be sure you are measuring/aware of the difference between CPU temp and battery temp; the battery doesn't get near as warm.

This is the only thing I hate about the Note II. It's processor is located where the ear-piece is so the top end of the phone will get hot. I had the same problem with SGS2... but the SGS3 has its processor located at the bottom, so you only felt hot at the bottom and not at the top. I don't know why Samsung went back to putting the processor at the top rather than bottom on the note 2. makes no sense.

If you are not using CPU intensive apps like games or A/V players, just toggle "Power Saving" (from the Notification page or from Settings), and it will limit your CPU at below 1GHz . This will not only make the phone cooler but will also, yes, save battery life.

I'm really impressed as my Galaxy Note II stays cool all the time. My S2 and even my old iPhone 4S was getting hot really fast, especially when playing games, but my Note II doesn't have this problem .

There are also problematic apps that stays in the background and on occasion gets itself stuck at full processor state. Use something like Elixir 2 or System Panel to monitor and find these apps (and then remove them). I just removed Minimalistic Text for this very reason, which is too bad as it's a very handy app.

Thank You!

I think I figured out what was my problem: I have several Gmail accounts. All were set up to sync everything, continuously... When I disabled it, all came back to normal.
I truly appreciate the help offered by members here. It gave me a perspective, thought me a few things and prevented me from returning this beauty to the vendor prematurely.
Thanks again,

How am I supposed to be notified of emails if I disable sync for the purpose of longer battery life?
It's odd that users have to resort to this kind of manual toggles for better life.

The Google accounts sync has subdivisions: you can decide on each of following whether to sync or not:
Calendar
Contacts
Gmail
Internet
Picasa web albums
I have on my Note II three Google accounts. To resolve my problem, now on one I sync all (except Internet), but on the other 2 only Gmail. In my case the phone seem to have had problems synchronizing the Internet. I am not sure whether on all accounts or in one of them only.
This way I get all my Gmail messages, which is what I want.

i have the sprint version and it seems to get warm in the exact area you are speaking of when searching for service. so far battery life has been great (something i've been monitoring for the last 3 days since i've gotten it) so i guess i'll just have to keep an eye on it and see.

On the galaxy S3 I had to do that to save battery. However, on the note 2 I have never had to do anything! It's that good on battery on its own. If i was you i would return the unit nd get another! I have had my unit for about 2 weeks now, and it has never overheated.

The battery life on my Note II is great. I had it the whole day on, moderate use, and at this point I still have 75% left over...

yes, but how much is "moderate use". That is the biggest problem that I have. As long as I'm going to have to use touchwiz i at least want good battery life for what my usage is.

OG Pro Heating and Screen Dimming

How hot does the OG Pro get? What is the maximum brightness you can set it to when the phone is at its hottest?
I've seen a Youtube video wherein a guy was playing a game for just 1 minute or so when brightness dropped significantly. That was for the Korean version though.

It drops to 76% at its "hottest" which is really just lukewarm heh. The only time it happens to me is when I'm outside in the sun (I live in orlando fl mind u). But honestly I leave it on auto at 50% and even in the fl sun I can see the screen perfectly...

LG PRO go or NO!!!!!
I would be very cautious of purchasing a phone with overheat issues, such as the LG G Pro. I had the privilege of owning and I have extensively tested the Galaxy 4, HTC one, and LG PRO. The LG model was the only phone that had overheated warnings and disabled brightness. I was in a well vented air conditioned building while testing. I am not stating all LG models will be the same. I will say look closely at how many people have had the device shut down or give warnings and it even happened during a CNET review. The LG phone is a great phone, just dont feel like you have to buy a device just because. I am pretty sure better models that don't over heat as often will soon be released.

Since the SGS4, HTC One and OG Pro all use Snapdragon 600, if OG Pro is the only one that "overheated", maybe it's safe to assume that a software update can fix this.

I chalk up any overheating issues to a bad phone. There have been reports of the S4 overheating and while I had mine it never did that and my OG Pro hasn't either so far. Its a mini computer so anything can happen.

I just played with a display model in the AT&T store. The phone was shut off and I used it heavily for about 30 mins running a combination of GLBench, Youtube video, Google+ browsing... The screen dimmed to 92% after running GLBench Egypt 4 times in a row and that wasnt such a big deal.. The worst offender was Youtube while watching video. I watched a video for just a couple mins and the display dropped to 84% and at that point I was really noticing how dark certain colors were looking, like greens and blues. The G Pro is such a gorgeous phone and I really want to pick this up but im worried about this display issue. A 16% display brightness drop while in an air conditioned building after a few mins of watching a video is a problem!
I can only hope for a software update to help this... Otherwise I may join the GN2 bandwagon.

No it is not. It's not a problem of the phone.
Would you mind watching this video?
How many models of top '13year smartphones do you know which allow you keep 100% brightness over prolonged period of time been well under heavy load (gaming, benching) at the same time?
The HTC One has autobrightness feature which silently lowers brightness w/o even notifying you about it. The SGS4 as you've seen, notifies you about the brightness level has been decreased and cannot be raised to full

Of course it won't

Well like I said I keep mine at 50% and can use it in full daylight. Ive gotten it to warm up a little but that was stressing it by playing dungeon hunter 4 over 4g and in the 90 degree florida sun. And even after like 2 hrs it only dropped to 76%. That just what I experienced...

There's reports on the sg4 and the one getting very hot this is a issue with all three phones wonder if its the 600 processor chip.

You can go to the hidden menu and disable the temp throtle. And the screen will be at 100% regardless of temp. But do it under your own risk. I actually got a higher score in antutu by doing it. But for normal use i keep it on. Only for games i disable the temp throtle. Theres a thread on how to do it somewhere in here.
If you don't find then: Open system menu by dialing 3845#*980#, go down the list, find items "High temperature property OFF" and "Thermal mitigation daemon OFF", check them both to Enabled ON & presto...with thermal mitigation daemon disabled you can achieve as high as 24700 in Antutu and the screen would not dim in hot conditions anymore.
Under your own risk. There's a reason why LG make this.

there aren't "overheating" issues. phones are computers and computers get hot, and phones can get hotter than most think is normal when they are actually just at normal operating temperatures. i have a nexus 4 and i have read about others getting their phone up to 90 degrees Celsius before it shut itself down because of the possible battery damage at this high of temps (this was when they were testing to see how hot it can get). even though my nexus feels hot the most mine has gotten to is about 50 degrees celsius which is well within the normal cpu range. now, hot batteries are a different issue, but the plastic in the ogpro is able to distribute the heat away from the battery, so the phone getting pretty hot is not an issue. i mean, obviously if your phone is getting up to 90 C then that could be overheating, but it doesnt sound like anyone has really gotten above 55 C which is perfectly normal and wont damage your phone even though it feels hot. if your worried about your phone getting hot then you can download "CPU+Temp V2" from the play store (its a widget) to see how hot your phone actually is. if you dont like the dimming screen then you can always disable it, but i dont think it is a big deal that it does it because i keep my phone brightness below 75 anyway.
stop worrying about your phone getting warm and just use it!

How do you disable it?

Mine gets E980 get mildly hot just like the Note II but the S4 gets so hot that it starts to lag trust met thats why i switched it for this one

I was having some high heat issues but did a soft reset and it seams to have fixed it... not to mention I have more free RAM and battery life improved a little...
The soft reset consists of removing the battery while the device is on and leaving it out four about 2 minutes. Then reinstall battery and turn on & presto problem solved at least for me.:thumbup:
OG PRO

The thermal throttling/shut off starts at 50C (122F) while the phones are able to go up to 55C (132F). Editing the thermald.conf fixes the throttling / shutdowns.

read me!
A genuine unbiased reply, cuz I have G Pro, S4 and 808!
G Pro is a beautiful butterfly!
Though It has some heating issues. The maximum brightness you can set at the "hottest" is 76%, while is 24% less than the max, anything above 30% would be excellent for indoors, believe me!(you will get habitual to it soon, its good for eyes and affects battery performance too!)
I have GT Racing 2 and Asphalt Airborne. While playing with brightness under ~60, phone doesn't heats up!
It does so only when the load is much, and the screen is above ~75!
(save for 60-75, its a no mans land.. lol )
In a (very)bright sunny day, you will have to use 100%, else 50% will do!
ONE REAL BATTERY KILLER IS IR-EMITTER!
Newbies usually blame huge 1080p screen for eating battery, but in this phone, the IR-remote(app/hardware, idc) is the real problem!
To save battery, avoid using remote, and disable Quickset SetUp and Quickset SDK in Setting>Apps>Inbuilt!
Else everything is fine!
FOR NEWBIES,
As far as 3rd party software support is concerned, I haven't seen any proper ROM other than CM 10.2!
For me, LG UI is better than TouchWiz!
Its Lite(Technically)
it has got themes(icons+widgets), animation effects for home screen, lock screen effects, dual-layout icon set launcher(these are main things most people need a custom launcher for)
Its fast(faster than S4-S600 and equivalent to Note 3-S800 for me!)
I love this phone!
Literally, NOT BIASED!
I MAINTAIN MY PHONE MEMORY(RAM) AND KEEP PURGING MY EXTRA TEMPORARY FILES
MAY BE THATS WHY MINE IS FASTER THAN YOURS!
NO OFFENSE TO ANYONE

[Q] Tab getting really hot when sd card in

Just got my note today and it is getting really hot, whenever i put the micro sd card in it really starts to heat up behind where the camera sit. Also i have battery doctor installed and at 60% it says that i only have 2 and a bit hours left on the device.
Ive turned off alot of stock apps and also tried another launcher (nova) my battery just seems draining real fast, thinking maybe a bum unit.
Anyone having these problems or some advice?

My tablet gets hot too, but Samsung devices are notorious for getting hot.
I've owned an SGS2 before and it got hot in that same area, and I have two friends with SGS4's (one a regular and the other the SGS4 Active) and those also get hot.
Our (yours and mine) tablets should be OK.
They shouldn't be bum units.
As for battery life, go into Power Savings and enable the settings for screen and processor (I forget the exact wording).
You can also use Greenify to force anything in the background from running when not needed. (Anything you don't actually want, you should freeze/remove altogether like you said you did. Greenify just makes sure that anything you aren't using isn't running unnecessarily).

Hmmm ive had the s2, note 2 the original note 10.1 and the samsung 8.9 and never came accross and heat like this. I just dont understand why it is as soon as the sd is in, I aint even running any apps jus leave it aline and it heats up while sitting idle.
Damn thing lol

Anybody else's phone heat up really easily?

I've only used my phone for light stuff like browsing Twitter, Reddit, etc., but doing so causes my phone to noticeably warm up as if doing some heavy duty stuff, especially if on max brightness. It heats up faster/easier than my Nexus 5. Anybody else noticing this? I think I'm gonna go to T-mobile tomorrow and tell them, but I wanna make sure that I'm not tripping.

Mine got quite hot when I was downloading a lot of apps in a row. It gets warm on normal browsing but not hot.

Same here, updating apps from the play store, video watching etc. Wil cause the back side, at the middle section to heat up.

I've been having that issue also. Haven't really figured out. Just know when that happens, battery drains fast.. think it's an app eating up battery creating heat but haven't figured out which one...

I am having the exact same issue. I'm thinking about switching my phone through T-Mobile and going with the M9 because I'm not hearing of this issue at all on the M9.

Yea. I'm definitely getting lots of heat on my S6 Edge as well, especially while running multiple apps while updating Google play apps.

yes I am also facing those heating issues..
I was first told that all phones get hot if you use them while charging but then it has happened thrice now even when I am not charging it.
The heat is pretty bad right at the end of your right thumb..

Had my S6 Edge a week and I'm surprised I haven't had any heat. I use the web a lot but I haven't played games on it yet.

Mine also
Mine is also getting hot with normal usage... I think I should move to SC

Yep. I also have the s6 Edge, and the heat was pretty much unbearable. I was within my 14 day return, so I have the HTC M9 on the way. It was reported HTC fixed most of the over heating issues with the M9 before launch. I will see. This phone will more than likely be returned to T-Mobile if Samsung doesn't come out with a fix soon. I could see this becoming a huge issue after launch since this phone is made out of glass and metal.

I had the Xperia Z1s which had a glass front and back and the HTC M7 and M8 and they all felt hot after using them for a while, once you put a case on them it gets less noticeable. I just assumed it would be the exact same since the S6 uses both glass and aluminum. But yes it does get hot after a while lol.

warming up
guy's i have same issue like u
but , i disable some bloatware useless apps , and warming is better now ,test it and let other knows.
test more ,and make this better

Mine only gets hot if I'm charging while doing a lot of stuff on the phone. After the OTA I did a factory reset and it seemed to fix the "always hot" issue.

Heating up is a good thing. It means you have a good thermal path from the internals to the external metal chassis. If the device stayed cool to the touch while working it would mean the internals would be at much higher temperatures and throttling would kick in to prevent breaching SOA.
That said, it should not get so hot that you cannot hold it, like a hot potato!

firmware?

I have a 64gb G6E running OCG.

Well i had an S6 for some days and then got the M9
I can easily say that the M9 is the same as the S6 if not cooler. It has already been proven that the S6's CPU reaches much higher temperatures than the M9 under a medium load
By the help of CPU-Z, it was detected that the S6 CPU reaches a whoping 66℃ if you just open the camera and take a pic
While in the M9, after a half an hour of Mortal Combat X, it reached 59℃
Mind you that these temperatures are CPU TEMPs not Battery/skin temps
S6 internal design is credited to be honest for putting the CPU away from the battery by a nice distance, so the battery doesn't heat up! When the CPU was 66℃ the battery was 31℃ !!!
But in the M9, the CPU is covering the battery, so when the CPU heats up, the battery heats up also. In the case when the CPU was 59℃ the battery was 45-44℃ which is considered to be warmer than the S6's 31℃
However the M9's metal casing helps in heat dissipation a LOT!! just leave the phone for a minute or two, and the phone will cool down very fast. It can cool down all over to 36℃ from 44℃ in three minutes!! Which means that throttling effect will be removed and you can enjoy your device's full potential again in the S6, if the phone heats up badly, the temperature is preserved as the glass is a bad thermal conductor. Also the phone might be very hot to touch in the upper right quadrant of the device in thr CPU side, while the M9 will feel warm all over the device.
So conclusion, the S6's 14 nm SoC heats up more than the M9's 20 nm SoC, but the skin temperature of the M9 is higher than the S6's but it is not annoying, and cools down very fast! If the S6 feels cooler, it is because the CPU is positioned far from the battery, not because it is built on a 14 nm process :laugh:

Note 7 temps

I got my phone a few days ago, and I'm somewhat dissapointed cause it always feels like it's running hot. I've never had this problem on my S7 edge. Just doing some browsing and its in the 94F range. Is this normal?

While it runs a little warm when charging, I've not noticed any excessive heat unless I'm doing something computationally intensive (Ex: transcoding video). But I know of one person that returned hers because of the heat. Have you checked to see if any applications are using excessive CPU cycles or are consuming the battery faster than others?

I haven't seen anything out of the ordinary. I'm barely using my phone to see if its gonna start to cool down but it's just consistenly in the 90F range with light use. I wanted to see how others experience are with their phones before I decide if I want to exchange it.

Depends on the ambient temperature, is that the temperature of the battery? If yes then it sounds ok to me.
You should download GSam and monitor the temperature. Since its made out of glass and metal, it will appear hotter to touch than a plastic phone.

Here ya go, note 7 recall due to fire Risk.
Samsung is recalling the Galaxy Note 7 worldwide over battery problem
http://money.cnn.com/2016/09/02/technology/samsung-galaxy-note-7-recall/index.html

Hope it doesn't explode lol
I would disable fast charging and turn on power saver.
Just to be safe.
Also don't wireless charge.
If yours is affected by the battery explosion issue, then don't risk it.
Wait for recall instructions and play it safe.

LOL. Yeah thanks guys, guess I'll return mine then and wait for them to make some new ones, sucks cause I really like the phone and already put in a screen protector and case

Question Disappointed in S22 Snapdragon Battery Life and Heating Issues

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.

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.
