So over the course of time I have used many different ROMs and also have had 5 batteries for my Note so far.
All ROMs gave me terrible battery life, except the stock android for around the first year, eventually it started giving me terrible battery life too.
So that got me wondering, is it possible that some kind of faulty hardware on my Note's motherboard is causing those battery drains?

I'm pretty sure that would be possible, but I'd make sure to rule out any other cause you can rule out first.
First thing to do is check on who or what is consuming the battery, so installing something like CPU Spy will let you know if the phone just keeps running at top speeds.
Because there simply isn't enough juice in these batteries to allow all parts of the phone to run full throttle for hours.
Smart phones are really at their best, when their just sitting idle and then they really shouldn't consume any power. That's what you need to check: Does it really slow down and sleep, when you're not actively using it?
And CPU Spy (or similar tools) will give you that info by telling you how much time the CPU has spent at each speed setting. If it doesn't drop to deep sleep when the phone if off the charger, screen switched off at the home screen but stays running at 100-500MHz, then you have found the reason for the miserable battery life. Now you'd just have to find what's causing it.
And that could be a long story journey...
However you could start with an empty ROM fully wiped, nothing but the ROM and the minimum set of GAPPS installed (and CPU Spy or similar for checking) empty internal SDcard, expecially no media files. If you have an external SD card, best remove that initially so you don't have to delete any data you keep on there.
If then the Note isn't guzzling battery and sleeping deeply when not used, your hardware is fine.
Then it's just a matter of adding item after item, always checking of that is causing any change to CPU states and energy consumption.
You should also try to find out of any of your five batteries has issues and use a known good one for the testing.

Okay to begin, the phone never drains battery when idle, never. If I charge to 100% at night around 23:00 , in the morning it would be around 90%. So that seems fair enough. Because I keep my EDGE / 2G activated at all times.
The real problem is when the screen is turned on (doesn't matter what I do).
I tried to keep the screen on for one hour, idle, doing nothing. Battery drained by a whooping 25%. So basically it's my screen which is consuming my battery. I didn't try this when I made this thread, so there's no mention of this in the first post.
So I don't think any other apps are consuming anything. Besides I hardly have any apps installed.
I got the gapps from the following link and installed the 'mini' package.
http://forum.xda-developers.com/par...apps-official-to-date-pa-google-apps-t2943900
Apart from I only have WhatsApp, Notepad, Perfect AppLock, AdAway and Chrome installed. Only a few apps since I did a full wipe yesterday night. Even flashed a stock ROM first and began from scratch.
So I don't really think it's any apps consuming any CPU, only screen is eating a ****load. Could it be the damaged screen?
Holy ****! I just recalled while writing this post, I did get this screen of this phone replace once, like one and half year ago. Could that be it? I did get it replaced from a official Samsung store though.

I'd consider playing with the brightness, just to see of something a little lower is good enough for daily use but I'd say that isn't impossible...
While Samsung liked to hype the fact that OLED would only use power on illuminated pixels, mine are mostly white because reading is what I do most on my Notes.
And then this screen on the Note 1 didn't use particularly less energy than a good LCD backlight screen according to the reviews I remember.
I also remember an article which said that the energy consumption on OLED wasn't linear and that the last 20% of brightness might cost 50% more power (the numbers are most likely bogus but the main point was that brightness/energy consumption wasn't linear).
And yes, there is most likely variation between individual screens on OLED and moreover OLED displays decay with use and over time. I haven't noticed it that much with my Note 1 yet, but my older Samsung Galaxy S I-9000 that I passed on to one of my sons developed a brightness issue: Everything below the first 100 lines or so is significantly darker than the top. I don't know wether that's a consequence of his usage pattern (Whatsapp) or some other reason, but I do know that he typically kept the display at top brightness and also kept it lit far longer than I ever did.
I've always been somewhat disappointed by the endurance of the Note 1 but I haven't really noticed any significant change with the different ROM versions. And since I was also somewhat disappointed by the performance of the device I couldn't resist replacing it with the Note 3 when that came out.
That device was better in pretty much every regard, except screen ratio: I really, really liked the 16:10 of the Note 1 a lot better than the 16:9 of the Note 3.

I see. Thank you for the time you took to write this reply.
I always have my brightness to the lowest possible and yet I am facing battery drains.
Anyways, it seems this problem is beyond repair. I have literally tried every solution possible and nothing seems to have worked. So I guess it's time to move on.
Thank you for your time and information.
It's probably my screen that's consuming the battery. It can easily last up to 20 hours with 2G turned on the entire day. But as soon as I turn the screen on and start doing something, battery drains at like 1% every 60 seconds.
How old is your battery?.. I´d say get a new one if it´s older than 1 year..
Morning all.
Something that has been slightly bothering me since I got this phone....it has a massive battery, it can be heavily customised with roms, xposed modules, magisk modules and all manner of tweaks. Probably one of the most open and dev-friendly devices I've ever had.
Yet, no matter what I do the only way I have ever been able to get more than 2 days out of a battery is to literally not use the phone.
I have had devices in the past such as Xperia Z3 Compact, S7 Active and others with smaller battery that were easily able to push 3 days with regular use. Hell, the Z3C was able to get up to 5 days with a little bit of trickery turning off radios when not in use etc.
Is the extra diagonal inch of screen realestate really enough to destroy the battery longevity? Typically with normal usage I am seeing 2 days with about 4.5 hours of screen-on time.
I've experimented with just about everything to push this out including no official facebook apps, decreased resolution, medium power-saving mode, kernel tweaks (currently using TGP rom and kernel), auto-sync turned off. Going beyond this I feel like you may as well just use a push-button device.
Any devs care to comment? What is the main factor that eats the battery on the Note 9? Is the exynos processor just not that power-efficient? Am I missing some hidden gem?
I guess the next step would be to transition to an AOSP based rom where the customisation is not constrained by baked-in samsung features but again, this is giving up a lot including proper s-pen functionality.
I recently kitted out an LG V30+ for my wife and it is just insane to me that a phone which only has a 3300mah battery can get the same life as the Note9 or better.
Is there some strategy I have missed or is this really the best we can hope for? Seems like an extremely inefficient use of 4000mah to me.

This is what you get when you use a high performance chip.
If it was like cars.. just because the gas tank is big (battery) doesn't mean that the engine won't consume the fuel faster than a more Efficient engine (cpu) with less power.
Other phones might be able to last 3 days, but they also dont have the performance capabilities. Turn on extreme power saving and see how long the phone lasts ...
I'm using stock unbranded ROM. I also adp uninstalled all the Facebook system apps (devil-ware). With Pie + OneUI + Night mode + Dark UI apps, it's the first time I love stock. I bet your non-stock ROM + TGP is the culprit.
I charge nightly on a wireless charge pad; easy on the battery. In Device Care, I run the default "Optimized" setting. I use it moderately for the first 12 hours of my working day (meetings phone calls), and I often have 85-90% charge left at that point. I then use the phone HEAVILY for the next 4 hours (watching video, reading, etc.), and at that point I am never below 50% (often 60-70) when I put it back on the charge pad, go to sleep, and start the whole thing over again. I have the US version (Snapdragon), darkmode and auto brightness is always on, and I use Automate to toggle my wifi off when not home and back on when home. Other than that, I have gps, bluetooth, and phone data always on. Bluetooth pairs with my watch and car, and gps auto-toggles by the kernel whenever I load maps or whenever my Life360 app updates my location (every few minutes).
That's all fairly normal use with a bit of power-savings thought into it. If you cannot get similar performance without your screen brightness jacked way up and wifi always on (that eats battery as you move around), then maybe you have a power-hungry app. Check your Device Care section of Settings, and start watching your "Usage by apps".
Also, it's better to slow-charge than fast-charge (wears it out more quickly). And you are better off charging nightly than waiting two days until it's very low.

A lot of people don't realize the huge difference that your cellular connection strength makes a difference on your battery.
Try working in a all brick/stone bank building, where 250kb/s is a good 4g download speed... Then see what your battery looks like after a few hours.

YEP!
And same goes for wifi.....
wifi and cell radios can really eat up battery if they are trying to maintain a connection in areas where wifi/phone signal is weak. And app like Tasker or Automate can toggle these on and off, depending on your location, and really save battery.
Well, that probably explains a few things. I moved in to a SOLID brick building recently with double glazing everywhere and multiple solid brick internal walls. First time I've ever battled for cell and wifi signal...that does explain a lot. I guess 2 days is still pretty good. Might end up with one of those 10,000mah Chinafones eventually ;p
So I had many Samsung phones before the S21 U and I never turn off the Always on display. When I put the phone (not the S21 U) on its face or cover the sensors, the always on display turns off, but this is not the case with the S21 U. AOD never turns off even when the phone is on its face or the sensors are covered. Is this a bug? can I do anything about it ? I want it to be like the old way.
Its not a bug, this has been the case since the S10.
Well, it's not a bug, but it's also not an unavoidable feature like the other dude said.
Go to settings, scroll down to lockscreen, tap "always on display", then you can choose always on, on for 10 seconds after tap, or show as scheduled.

It would be nice if Samsung let you choose more than one AOD option. It would be great if you could both schedule AOD on hours plus enable tap to display for 10 seconds.

Actually it is indeed an unavoidable "feature" that was introduced since the S10 series. He's talking about the fact AOD used to automatically switch off when the phone is in a pocket or face-down. That is, despite the setting of "Show always" being toggled, the AOD would still switch off when in a pocket or face-down. The reason for this being that if it's in a pocket or face-down, it's pointless having the AOD on. The advantage of course is that battery life is saved.
An obvious example scenario is when one is out and about for say a 14-hour period with the phone in their pocket or face-down about 50% of the time. This would mean the AOD is automatically disabled for 7-hours (while in the pocket or face-down), saving about 7% of battery life. To clarify, the AOD automatically turns on for the other 7-hours when the phone senses that it's outside of the pocket or face-up. I've come from the S9+, and I can certainly confirm that this feature saves battery.
For some reason, since the S10 series, Samsung have disabled this feature for AOD. I can't find any information as to why, but it must be related to the proximity sensor and how it interacts with AOD. Otherwise another reason is that Samsung felt no one liked the feature (can't really imagine why) and disabled it without giving any option to enable it.
Ah I missed the part where he was specifically concerned about the proximity/light sensors shutting the AOD off, just thought his problem was it just never turning off.
Please reconsider - are you sure the feature actually saves battery (face-down or covering sensors turns off AOD)?
Remember we now have a very good display with adaptive refresh. Maybe Samsung designed the screen to be good enough in AOD to actually use less power than running the proximity sensor (to turn on and off AOD) all the time.
So it's a false comparison above - it's not "free" energy savings when you had that feature. The phone had to use power to activate the proximity sensor to know whether to turn off AOD, and it took power to turn on/off throughout the day. But maybe now, why should Samsung bother with that, if they figured out it's less power to just have AOD all the time and not power the prox sensor?
Bottom line, why waste power on running the prox sensor when you can instead use that power to show useful information?
This is speculation, I don't know the actual power loss caused by the missing feature. I just want to correct the assumption that it's free power, when it's not.

I suppose that could be viewed as a good point, although it's actually still a disadvantage or "downgrade" compared to having the original "power saving" feature. This is demonstrably proven (at least for me) given having AOD enabled loses about 1-1.3% battery per hour, which is similar to previous Samsung phones. With AOD disabled, the battery loss is closer to 0.3-0.7% per hour.
To clarify, your argument is that having the proximity sensor activated while AOD is enabled may actually use at least as much power as always showing the AOD when the phone is in standby. Again, I would say this is a "downgrade" compared to previous models, as the proximity sensor should never use this much power (and we know the amount of power the AOD uses is similar to previous models, as demonstrated above) - if it does, then it's arguably a "design flaw" by Samsung. That is, they would have made the proximity sensor a "battery hog" in a relative sense.
Odd, my AOD set to "touch to show for 10s" doesn't even use 1% in 20hrs with 8-10hrs SOT. Snapdragon US model from Google Fi.
You'd think samsung would have more consistency in these, especially by now.
AOD uses very little battery*. Cell standby and device idle together use more.
*if you use a simple clock and don't have all kinds of needless garbage.

I should probably clarify a few things here.
-With AOD set to "touch to show for 10s", the amount of battery AOD uses should be entirely dependent on how often you enable it by tapping to toggle it on. If you tapped it 1000 times in 20 hours, verses 10 times, it would obviously be quite a different amount of battery use.
If the AOD is set to "show always", it could be viewed as essentially the equivalent of continuously tapping to show every 10 seconds for the 20 hours you quoted. It's therefore clear that it would use more than 1% in 20 hours!
-My description of the amount of battery loss from AOD being set to "show always" verses completely disabled was actually regarding total "standby drain" per hour. That is, with AOD set to "show always", the total standby drain per hour (eg. overnight) appears to be around 1%. With the AOD completely disabled, it's closer to 0.5% total standby drain per hour.
The above numbers have been fairly consistent across all Samsung smartphones I've come across, although I suspect the S7 was one of the best (since 2016) in terms of least overall "standby drain" per hour even with AOD set to "show always" (if I remember correctly, it was closer to 0.5% per hour drain with AOD always toggled on, and 0.1-0.2% per hour drain with AOD disabled).
Note that these figures are without any "de-bloating" or "rooting" of the phone.

My previous phone, a Pixel 2XL, I had set to AOD always on. The phone would turn the display off when face down and even when in a holster on my hip. At night it would stay on all night as a night light/clock right next to my bed and my charger would come on via timer an hour before I would get up to recharge.
It’s very disappointing that the S21 Ultra, brainlessly just keeps AOD lit nonstop despite the fact that it’s a deluxe phone with enough sensors to be programmed just like the Pixel 2XL, which did much better with AOD and its effect on battery life. I’m hoping Samsung fixes this in an update real soon.

The power used to light the display is very small vs the background processes already running.
Pixels have no SD card* slot because Google wants you to be cloud dependent.
You aren't viewed as a customer by Google... you're the product. Getting off their factory devices is a start in the right direction.
*No SD card slot is completely unexceptable.
The SD card is the data drive or should be.

When I first got my S21 Ultra I set AOD to always on and battery life suffered greatly compared to my previous 2XL. The S21 Ultra doesn’t have an SD card slot either, which has nothing to do with my comments about AOD performance between the 2XL and the S21 Ultra. You are correct, it’s great getting away from Google, but the only real alternative is an iPhone or custom ROM with Micro-G on an Android phone, which again has nothing to do with AOD performance.

It's irritating Samsung chooses to do that on some of their phones. Worse it varies from year to year with the same model sometimes too.
AOD in it's always on mode at night if you're not using the phone should use roughly .75-1% an hour. Usage isn't always reported correctly to the apk responsible. Lovely isn't it?
Try clearing the system cache.
If you did any major firmware updates a factory reset is in order otherwise it's not going to get to the root cause most likely.
Samsung's are notorious for this kind of behavior but it can be sorted out. Cloud apps including Google Backup Transport are prime suspects.
Disable Google Firebase and all carrier, Samsung, Google feedback for starters.
Karma Firewall is very useful; a VNP firewall that uses almost no battery, no ads... true freeware.
It's logging feature may not work with Q and above. An adb edit to correct that may be possible, not sure.
A package blocker is also very useful and a powerful tool for unrooted phones. I've used this one for years with zero issues.

Once I disabled full time AOD my S21U, battery life is no longer an issue. As I stated previously, I would like to see a Samsung software update making their AOD perform similar to the way it does on a Pixel 2XL.

It's not AOD.
Samsung's can be... complicated.
This is how much AOD uses on my 10+, it's an accurate estimate. This is after I spent a lot of time to optimize it ie get the bugs out.
A few additional points/queries about the S21 Ultra:
-I've calculated the total extra battery % loss per hour with AOD always enabled to be around 0.5-0.6%.
"blackhawk" post above suggests that for the 10+ phone, the loss is more around 0.3-0.4%. This appears to correlate well with what I've read regarding the AOD on the S21 Ultra running at 120Hz (which would increase battery use compared to if it ran at 60Hz, which the 10+ phone presumably runs at). It's a pity this is the case, as I don't see any advantage for AOD to run at 120Hz. Perhaps in a future update, Samsung could reduce this to 60Hz on the S21 Ultra.
-I note a couple of users in this thread "hoping" that a future Samsung update will allow the AOD to automatically switch off when face-down or in a pocket/bag. Unfortunately, I don't see this happening, as this feature appears to have been "lost" since 2019. That is, this feature was last present on the S9/Note 9 series of phones back in 2018. All Samsung (flagship) phones from 2019 to present have lost this feature.
-Does anyone know of a way to change the AOD font size (without installing extra software)? Reducing the font size would surely be another way/option to save battery life while having the AOD always enabled.

Wow, you got your AOD power consumption down to 3%! The first week I had my S21U, AOD was using 25 to 30% daily I believe. Can you please tell me what you tweaked to get your phone’s AOD power consumption so low? That’s better than on my Pixel 2xl.

I'm not sure what is causing that. Something is running in the background; the phone's not going into deep sleep. Maybe a messaging or cloud app. Usage apps can misreport which apk is the cause or it could be a dependency.
Try it in safe mode to rule out 3rd party apps.
The Google system apps are prime offenders as can be the Samsung apps.
Try clearing the memory cache then see which apps pop up first. My version of Device Manager can do that; I've used it to find rogue apks like that.
Hi everyone.
Just wanted the community's opinion on what your thoughts are about the AOD.
How many of you use it regularly? And those that do, what is your preferred setting - Always on (+/- scheduled) or Tap to Show for 10 seconds? What has been your experience with battery life and overall usability? Any tips or tricks? Any downsides?
Those who don't use AOD, could you please post your reasons, along with any experience with battery drain or screen burn in or other issues.
I'd like to use AOD (on the always on setting), but am not very sure what it costs in term of battery or screen life. The former is a non-issue for me personally but if it's going to affect screen life or quality, I may hesitate a little. I tried the tap to wake for 10 seconds thing but it seems to beat the purpose as I can just as easily go to the lockscreen with a double tap and neccessitating user-interaction negates any real benefit of an always-on feature.
My current settings are:
AOD Always on (scheduled from 7am to 10pm)
FIngerprint reader always on (so I can go directly from AOD to Homescreen without having to go through the lockscreen)
Fingerprint icon set to tap-to-show (just as a hint if i ever miss hitting the correct position when trying to unlock)
Your thoughts and suggestions are most welcome.
I only use AOD via AODNotify...that should have been an option in the poll.
I use a Tasker profile to turn AOD on (always) when a message arrives and revert back to tap to show when message is cleared.
I keep it on all the time, really helpful and doesn't seem to drain too much battery.
Btw does anyone know if it's possible to add weather info to the S21Us AOD?
One of the few things I still miss from my P4XL..
I don't use it drains a lot of battery
I use to always have it active on my 10+ but it got to be annoying. Tap on is fine.
I don't care to be informed every bloody second... that ain't no way to live.

Wasn't even aware something like that existed. Thanks for the heads-up, will check it out.
Poll updated with new option.
I like to keep the setting to always on with fingerprint always enabled showing thumbprint on screen always .
What i have noticed is the aod doesnt turn off when the phone is in pocket or lying upside down.
That would save so much battery.
AOD used to turn off automatically in my s9plus when the phone was in pocket .
May be this feature is disabled due to lack of active proximity sensor

The 10+ has a proximity sensor and AOD always remains on if set to. The face down off be nice.
Maybe it caused issues in the past. Samsung is sort of hit or miss though.
I have yet to use the fingerprint sensor, lol don't even know if it works.
Last thing I want is to get locked out of a device.
As soon as you set an access password this can happen and through no fault of your own. A hardware failure or glitch can trigger it. Had no password been set the setting wouldn't be enforced. I've gotten locked out of a PC bios like that, never again.

Does the fingerprint icon shift around like the clock or battery percentage (it has very little room to move around though)?
I hope it does, otherwise it'll land up causing screen burn if it's in the same position with the same pattern all the time. Have you noticed this?

Probably shifts it over a few pixels but in bright light over time it will cause uneven aging.

According to your battery stats, how much drain is attributed to the AOD? Could you post a screenshot at the end of a day please?
I don't know how much drain is attributed to the AOD. As soon as I get the newest Samsung I turn it in and crank it up before I literally do anything else. I keep every setting on ALL the time (Bluetooth, wifi, nfc, etc). The battery gets me through a regular day. I'll try and post a screen shot. Today I took it off the charger 3 hours ago and I haven't stopped using the phone. I'm sitting at 85%.

I have a serious addiction to smart phones, lol. I'm on mine about 12 hours a day. Mostly playing games or surfing the net. Today off my charger for 2.5 hours and I'm at 88% lol.

Cycle the battery between 35-65% if you can (and then raise both those numbers slowly over time) or else you will fry your battery fast.
If you're just going to buy a new phone in 2 years, then, don't bother with what I said.
Hi everyone,
I got my new S20 FE just a few days ago, and I'm still getting used to it, but I wonder if having to charge the battery every day on average is "normal" or not.
When I plug the phone into the charger, the battery is never flat. Rather, it's hovering at around 30%, and I usually stop charging when it reaches 85 to 90%. I use the 15W (?) charger that was in the box, so no ultra-quick charge for this one.
I tried to plug it into a Xiaomi/Poco 33W charger for a few minutes, just to see if it would speed things up, but the remaining charging time was the same as with the regular charger so I reverted to it, just to be on the safe side.
Still, I wonder if it's normal to have to recharge the phone every day, when my Poco X3 Pro needed to be charged every two days on average. Granted, the Poco has a bigger battery, but it has an LCD screen instead of an AMOLED.
I spend a lot of time on Twitter, especially in the evening, mostly, but that's it. No gaming of any kind.
What say you?

Hi,
I've turned Auto brightness off. I'll tell you if it changes anything in terms of battery life. I've also set AOD to fixed brightness instead of auto.
Thanks for the tip!
No problem, thank you for the question!
I think that debloating is not a bad idea, also try to go to all individual apps settings and set the battery to Restricted, except mail and messaging apps, so they won't drain the battery when you're not using them. Lowering the screen refresh rate also helps a bit, as well as restricting mobile data to 4G only, if you don't need 5G. Also, you can limit processor speed, turn Adaptive battery on and Enhanced processing off.
Hi again!
I've changed network settings to 4G and below since my SIM doesn't give me access to 5G yet, but battery life was still iffy. I then changed the network settings to something called "GLOBAL", and it's a bit better, though I don't know what that setting does exactly.
It also depends on how much your using your phone, what apps your running (games vs non-games, etc).
For example, I've played some games, but mainly have been on the internet via apps like social media, email, web browser.
I'm currently at 55% And it's been over 24 hours since I last fully charged it. The Battery graph says based on how I've been using the phone that I still have about 1d 3h left.
I do usually charge once a day, but it's definitely more than 24 hours after the last charge. I went to bed last night with over 62% left after having charged it probably 12 hours prior. When I woke up this morning, it was done to 59% and since then, is now at 55%.
So I've been pretty pleased with the battery life for me. Whether that's good or bad, I have no idea but it's definitely better than my last phone.
I don't do games on my phone (in fact, I don't do games at all, period), but I think the AOD being set on automatic lighting could have something to do with my relatively poor battery life. I'll try to set it to a fixed brightness and see if it changes things, though the brightness scale is pretty rudimentary. Maybe the light sensor is turned off when automatic brightness is off.
I usually spend more time on Twitter when I'm on the phone, so this could explain that.
Another possible factor is my application launcher: I use Microsoft Launcher, which I adore, but every time I wake up the screen, it does a position fix to update the weather widget. That could also explain why my battery drains faster than I expected.
I've just set AOD to fixed brightness. I'll tell you if it helps or not. Thanks for your input anyway!

I used to use Microsoft Launcher, but then switched to Nova launcher. However, since getting this phone, I've moved to OneUI and I'm loving it. I haven't really changed anything. AOD is set to whatever it was out of the box and I've been on Twitter and the web since I last posted and I'm currently at 53%.
I think I have seen MS Launcher be a battery hog if I remember. Nova isn't as bad, but OneUI seems to work great.
Also, the number and type of widgets you have installed could also cause battery drain. For me, I only have one screen. I use smart widgets to "stack" widgets I need which are calendar, weather (from WeatherBug), Brave Search, PowerAmp (for music) and then the phone maintenance widget. So far, battery life is pretty good like I've said.
You can also go into Settings->Battery and Device Care and maybe check in there to see what might be eating up your battery the most.
I like the look and feel of MS Launcher, compared to others (I believe I've tried them all over the years...), even if I have to admit Nova is a close second. MS Launcher is a possible culprit, obviously. I may switch back to One UI to check how things are going, I don't know.
I've just topped-off the battery, and just idling, the phone is supposed to last over 2 days until the next charge, but I know it won't last that long.
So I got my phone used (only 2 months, still has back poly attached) and it came with august 1 update and the battery drain on it is abysmal. I can see the battery go down while I'm browsing insta or whatever, not even gaming. You know what instantly fixed it? Downclocking my gpu and cpu using FKM. But this is not a pretty solution as it requires root and I would like to experience stock without root for a bit.
Which makes me think the system isn't properly downclocking the soc when idle leading to increased drain. I would like to know if anyone has a better fix than just disabling all the options on your phone.

Well, considering it's used (was it refurbished or did you purchase it off eBay or some other market)? That might be why it was being sold. You said 2 months. Does that mean it was only used for 2 months or you've had it for 2 months? If the phone itself is only 2 months old, who knows how the previous owner used the phone.
Did you do a factory reset when you got it to ensure it was back to stock settings? If so, then it might be your battery is bad and could be the reason it was sold/returned by the previous owner. If you haven't factory reset it, that is possibly the only other option that I can think of if you've already rooted and downclocked it.
Mine was new when I got it a few weeks ago and the battery lasts 1.5 days for me, even with the refresh rate set to 120 Hz. And that's with moderate use (playing games a bit, browsing the web, texting, phone calls).
You might want to try setting your screen refresh to 60 Hz to see if that helps as well if you haven't done that yet.
Go to Settings->Display->Motion Smoothness and select "Standard" to set it to 60 Hz refresh. That will save some battery as well.
See if that helps as well. If not, and as I stated, if you haven't done a factory reset, that might be your only other option unless someone else has something I haven't thought of.

Yeah I got it from a store second hand. Came with the back poly still attached and no damages on the body. A killer deal. As for the battery issue, I had flashed wrong region stock rom. After learning what csc meant and figuring out I was on the wrong region I flashed the right rom and now my battery life is top notch. On a side note it has only 54 charge cycles after I got it.

Glad you were able to figure it out. Even though the phone is reaching 2 years since it's release, I've been very happy with it. My S7 finally died over a week ago after 5+ years of dependable service.

This is actually the second device I bought this year. At first I upgraded my Redmi Note 5 Pro which gave me 4 years of great service. Could have reached 5 but then I would not be able to exchange it so I did and got a Redmi Note 11 Pro Plus 5g. Considering how much I paid for it I was more or less satisfied except the camera. Then I bought this after months of careful consideration and also because it was a killer deal. I got a brand new device for half the price. Flagship specs at 33k bdt. You can't get a better deal.
