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
I just switched from having iPhones all my life to the Samsung s21 ultra thinking it was the best possible android phone to get but it’s literally uselsss. It goes from a full charge to almost dead after playing a game in about 2-3 hours. In comparison my iPhone 11 which I hadn’t charged in about a day than played the same game for about 6+ hours while having YouTube playing in the background still has enough battery to go on for hours. It literally goes from 100% to 95% just unplugging and looking at notifications… idk it seems I’ve made a huge mistake… I watched many reviews prior to buying it and they all said the s21 got hours of use before a charge.
my s21 spends more time charging than any actual use and I’m left with having to pull out my iPhone to play games and watch YouTube. Hell it’s charging right now and I’m writing this using my iphone…
is something wrong with s21 ultra or is this normal ?? Should I try to exchange it ?? I just got it like 5 days ago.
I charge mine once a day (at night while I sleep). And average 5-6 hours of SOT... Great battery life IMO.
You're burning up your battery.
2-3 hrs of high intensity gaming is a lot to ask from such a compact device. A least give a break every 15 minutes. Even watching vids I give my 10+ a break every 20-40 minutes even though it's using only 2-4% more power than when browsing the web.
The big question is how much battery is it using when idling and doing light tasks SOT?
Roughly...
Should be around 6%@hr
Browsing Brave 7-9%
Vids 9-11%
Screen off AOD always on, >1%@hr
Screen off AOD tap on >.5%
This is what a optimized 10+ is getting. Yours won't be the same but if there's a huge 10% SOT difference it's because there are apks sucking it dry. The AOD night rates should be very similar.
In fact the S21U with a 5000 vs the 10+'s 4300 mAh battery should do better. The S21U's memory is about 20% more efficient and the CPU should use less at idle. The wild card is Android 11 which I'm not found of, vs Pie with no scope storage. That said I think you should still be seeing similar run times.
What's eating the power? With Android you have options, many of them unlike plain Jane Apple*.
Is your screen brightness greater than 50%?
The display gets very bright and eats a lot more current as you go past 40%. It also wears out the AMOLED pixels a lot faster past 50% and maybe your retinas too.
Do not use in direct sunlight. Not only bad for the display but the sun's IR energy can overheat the little greenhouse phone rapidly.
AMOLED displays eat almost no current when black. Bright wallpapers do. Big bright icons do.
After the display consideration look for apks that are using too much and correct it.
Try disabling all power management for now except the display/power mode. Address each problem app separately and their dependencies.

The only NON-root solution that let’s you disable any unwanted packages that come pre-installed / installed with your phone / tablet.
www.packagedisabler.com
Disable Google Firebase, and all carrier, Samsung and Google feedback. Disable cloud apps if not needed. Keep trashware like FB, WhatsApp, Instagram, Twitter, etc off the phone. Privacy, security risks as well as battery hogs.
Use Karma Firewall to block internet access to apks and services that don't need it. It's freeware that uses almost no battery.
Use the native launcher, it's fast, very stable and very customizable.
That's just the beginning...
*stock Samsung's are the most customizable phones on the planet. Use the Galaxy Store themes and icon packs, hundreds of free ones.
Use the Good Lock family of customization apks.
Use Sound Assistant.
You can spend months playing with them alone.
I've used Apples and I hate them. They run well but are so limited compared to Androids. That plain Jane bores me to tears. Android are what you put into them. Nothing in, nothing out.

If you're unhappy with it, best to exchange it and go for the iPhone 12 Max. Especially if you are already comfortable with the apple ecosystem. There's no point being frustrated with your most used device, especially after paying top dollar for it. Personally, I would switch to an iPhone in a heartbeat if I thought they offered value for money (according to my standards) and if iOS allowed for a level of customisation I've come to love with Android. Biggest reason I can't do that is that I don't like Apple's way of doing things as far as software is concerned.
As far as poor SOT is concerned - 2-3 hours is indeed quite less, even with a game. In my experience, the S21U has pretty decent battery life (albeit not as great as my brother's iPhone 12 Pro Max), and it's in line (if not better) with other phones running the SD888 (very comparable to the E2100), but I haven't tested it with games.
Just curious, what made you switch over from a lifetime of iphones to the S21U? It'd be interesting to know an iOS users perspective.

Even the newer iPhones use an OLED screen. They too run on Li batteries. If the usage is similar on both phones, 2-3 hours should'nt be a lot to ask from either device, right? Clearly restricting or modifying the user's behavious to cater to a device's personality shouldn't be the solution.
I guess each of us have different priorities and expectations. Your preference seems to be to disable everything that make Android phones so great - dim the 1500 nit screen and don't use in outdoors? Stop playing an engaging game every 15 mins? I'm sure it works in your use-case, but not everyone spends $1000+ for a crippled phone.
Then there's the fact that you have an entirely differnet device with a two generation old OS and completely different hardware!
The OP asked if he should exchange his device, if the S21U wasn't living up to his expectations, given his background of lifelong iPhone usage. The discussion wasn't about how to change his phone usage habits and teach him how a phone should be "properly" used.
There's a whole gamut of metrics to look at here: 1) iPhone screen resolutions are nowhere close to S21U's, 2) iPhone 11 doesn't come in 5G but S21U does, 3) iOS games are far better optimized for the OS than Android's, 4) Screen brightness, 5) background activities.
It's easy to pass a judgement before considering all the factors. I'm justifying that the S21U is better than iPhone or vice versa but you need to consider a lot of factors before closing an argument...Just my 2 cents

I agree with everything you just said.
Each person has to decide what is more important for him/her and choose accordingly.
No single phone is 'best'.
We get the device we like and need, and choose which compromises we're willing to live with.
In my example, I can't stand iOS, so I choose to live with Android. And among all phones out there, the S21U is my device of choice, with all its good and it's bad. I wouldn't exchange it for any phone out right now. But that may not be the case with everyone. For the OP, if long hours of gaming is a requirement, then the Apple SOC and optimised games push the dial towards iPhone.
If your battery is draining that quickly, there's a good chance it is defective. Before jumping to this conclusion, I would reset the device, keep it clean for like a day to see if the drain is still present. It would help to disable things like GPS (amongst other things) to see how much charge you lose over a few hours. In my experience, not all batteries come out the assembly line at 100% health - the same way that some products have defects while others don't.
If you have the option, contact Samsung, notify them of your experience. I have seen reports of people getting excellent battery performance on this phone. I have used Samsung devices in the past where battery life was really good. I wouldn't be so quick to write them (or Android for that matter) off.
Hope this helps.
I don't game, but here is about an average day for me. I could easily get another hour of SOT out of this.

Disable Google Firebase, and all carrier, Samsung and Google feedback. Disable cloud apps if not needed. Keep trashware like FB, WhatsApp, Instagram, Twitter, etc off the phone. Privacy, security risks as well as battery hogs.
Use Karma Firewall to block internet access to apks and services that don't need it. It's freeware that uses almost no battery.
Use the native launcher, it's fast, very stable and very customizable.
That's just the beginning...
*stock Samsung's are the most customizable phones on the planet. Use the Galaxy Store themes and icon packs, hundreds of free ones.
Use the Good Lock family of customization apks.
Use Sound Assistant.
You can spend months playing with them alone.
I've used Apples and I hate them. They run well but are so limited compared to Androids. That plain Jane bores me to tears. Android are what you put into them. Nothing in, nothing out.

Solid, useful reply all around! Social media apps and google/samsung telemetry hurt your battery and privacy. After removing ones you don't need, you can use Blokada or another firewall to block trackers and ads from what remains. Tech tends to be better when kept simple.
My S10e gets around 6h SOT with most apps disabled through ADB, zero google apps except for play services, and F-Droid + open source apps for most things. I wish I could run a degoogled ROM with MicroG, but this setup is 80% of the way and Samsung's customization without root is solid.

Now that you're not roasting your battery continue pick away at the serial offenders.
Try to get the SOT in the 7-11%@hr range.
Remember to clear system logs and clear the system cache.
Global ad blocking?
Easiest way...
I get over 19 hours on a full charge and play lots of games. Go to Settings > Battery and Device Care > Battery the touch the graph. That will show you which apps are using the most battery. Some games use a lot of battery up. And if you have Tiktok or Snapchat on your phone then those are known to cause battery drain.
Return the phone, 2 - 3 hours SOT is nowhere close to normal, even if you haven't optimized power consumption.
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.
Try the following:
1. set battery saver in battery menu
2. set auto start on for your favorite messenger app, i did for whatsapp
3.set gmail autostart to off if applicable
3.5 set your always running apps like music player out of battery saver
4.put display rate back to 120, it is much smoother for scrolling but keep at FHD.
5.keep AOD turned off. not a big deal for me
6. i am on wifi always (hotspot or at home) and set to cut mobile data to off after 5 minutes. you may not want to do it
7. set remove cache in 1 minutes
i am now getting a vastly improved battery life with not tangible downgrade on my daily use performance. i am not a heavy user and do normal things daily (not a fan of gaming on mobile).
Finally the battery saver does not seem scary, seems a lot of power under the hood that we do not need on our normal daily use.
Honestly, u bought a flagship smp with powerful chipset, wqhd+ display
Then u turn on battery saver to lower the power of chipset, turn display to fhd, turn off some function just to have some little extra battery which can be charge full at only 45-60 mins?
What is the logic here?
I agree with you that you buy a flagship to use all the high specs but with the above changes i noticed little diff in daily usage experiment, anyway it depends on your type of usage. For example If you start heavy gaming, no point to be in battery saver mode. If you buy an 8 cylinder car no need to always be on 8 if you drive in city at 50 km and burn so much fuel. I think the full power of chipset is a reserve and is overkill for ordinary jobs.
For me it was a very good feeling that the battery drains much less when idle and when you use it and was giving me more of a flagship experiment.
I couldn't notice visually FHD from WQHD+ but 120 Hz is noticible, may be it is me. So i kept it on. For gmail, it is ok if i sync from time to time myself or when i am waiting for an immediate email.
My phones last to me 4 days, always. People just shoudl stop breathing via phones and there will be no problems with batteries.
idle time 8 hours at night i lost only 1%!

If it lasts 4 days it means your putting it in a box and leave it there for 4 days.
Anybody that uses a device like that (not using it at all) just wasted good money on a flagship. You should be fine with a $100 device.
