Although to a certain extent, we even came to doubt that Samsung would update the Galaxy S9 and Note 9 devices with the OneUI 2.1, it is finally here, and it cames with Deep Sleep Apps feature, which will allow to actually suspend all services and processes associated with an app.
This has resulted in a relatively big battery life improvement when the device is on standby with S10 and S20 devices in controlled tests1.
Galaxy S9, S9+ and Note 9 are devices released more than 2 years ago, and surely the battery stamina is not the same as they were in their first months of use. Samsung stats that the batteries used on these devices should keep a decent stamina for 2 years with the average user.
Some people have used their phones with battery care measures1, in order to extend battery life.
So, with the recent release of OneUI 2.1 for Samsung Galaxy Note 9, the battery life with the device in standby is expected to be longer (but not the screen on time), although the magnitude is yet to be determined in the coming days.
This thread is aimed to share our opinions on the subject, as the update becomes available and we can evaluate the battery life.

IOS uses a choise in his battery settings to charge the battery up to 80 % of it's capacity and then charging will stop to improve the battery's durability.
It's known that standing in battery's 20/80% capacity increases its life and durability and doing this you can charge how many times you want because one parzial charge will not be counted as an whole cycle of charge so the battery might last more than 3 years going on like this.
This choice is not implemented in Android even with one UI 2.1 and it's a shame even if the new feature will improve battery's autonomy due to the lower consumption of the apps and even if it's impossible to perfectly be able to stay in it's 20/80 percentage range, there's an app that I found that will avert you when reaching 80 % of its charging capacity so you can disconnect the cable to preserve the battery....

You're right and I keep charging between 30 and 80 but this shouldn't be how the phone charges by default as you said. Many people charge from 15 to 100 and want that extra 40-50% they'll get by doing so. I found that without fast charging it takes 1 hour from 30% to 80% so it's no big deal to look at the clock when you leave the phone on the charger.

Even your right, there are even people that continually from 0%(completely dead) goes to 100% after charging the battery for the whole night... that's why what I said for charging should be a choise (like in IOS) and not a default setting.... strange thing that Android or Samsung didn't consider implementing this choise. Fast charging even worns the battery first... it stresses the battery and it will last less but at least they gave us a choise in using it or not.
Absolutely true! Samsung should have implemented a feature to limit charge at 80%, or implement a Bixby Routine to enable this behavior (for example, when charger is plugged at night)
50% increase in my case. And i used OTA Package to update manually.
From: 4h SoT in 24h
To: 8h SoT in 24/30h
Idle times are impressive.
EDIT: just FYI, i rarely charge up to 100%. So my average case is from 85/90% to 5%. Very rarely do i go for a 100 to 0.
One UI 2.1 improvements are all courtesy of the Deep Sleep feature.
I've added everything i barely use or dont need to create wake-ups on the Deep Sleep list. On the normal sleep list, i have low priority things like Play store, etc. And i make sure i white list everything i need untouched (Messenger, WhatsApp, etc) and also do the same thing on the Memory management. Solid results.
Edit: 100% to 1%. 10h SoT with a 30h cycle. It's like getting better and better.
My tab a 2019 has the 80 percent feature and I do not understand why they wont offer the simple setting actually I do because phones they want you to replace the phone instead of the battery in 2 years. I run my note 9 from however low to 100 every night but only because I dont have the option these newer android 9 then 10 now 2.1 adding more and more apps into the firmware but wont add a simple little feature as this. Also I would like to be able to choose if I want to do ota with my data! But I cant.
For me One UI 2.0 was already worst with about 3 to 3.5 hrs of screen on time. Now with 2.1 i barely get close to 2 hrs of SoT. My note 9 is running stock since i bought it at launch and have never done any factory reset. Only thing i do is wipe the cache after a upgrade.

Bro you need to factory reset and start fresh and if that doesn't help something is wrong with your battery I get 9 SOT all the time with 10 2.0 with android 9 it was about 6 SOT, I haven't received 2.1 yet. I have us unlocked version.

You have a snapdragon variant which is anyway much better than exynos variant (my phone) for battery backup.

Stop saying Exynos is not good for battery life. I can easily get 8h SOT of regular usage on my SM-N960F running OneUI 2.1. Obviously I don't play games like Asphalt 9, etc but I never use power saving modes and never limit myself in order to save battery life. I play 8 Ball Pool when I want to, I watch YouTube for as long as I want to, I browse Instagram and use Samsung Internet Beta when I feel like it. Not once have I ended up in a dire need to recharge when I was outside or when I needed to use the phone. Also the phone charges 50% for 1h (I charge between 30 and 80%) so I just leave it charge while having dinner, watching TV or something like that - when I normally wouldn't use the phone anyway.
On my N9 seems battery life abit improve from previous 2.0. Sammy did great job this time.
Here is my screenshot to prove it.
It takes time to see improvement in your device's battery life after installing OneUI2.1. As the software AI needs to learn all your habits again before any improvement in battery life will occur. This process should take a few weeks

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the Samsung Galaxy Note5 before depleting the battery.
Then, drop a comment if you have anything to add!
SOT is usually 1 hour 23 minutes at 50%. With the Display brightness a little less than half.
The biggest culprit is Android OS stay awake time is always high.
Man I've been more than impressed by my SOT of the Note 5 compared to my crappy old Nexus 6. I can get 4-5 hours on here vs the 3 hours max I got on the N6. Blows me away. So much better phone than that was too.
I normally see about 3hrs on nougat where as MM I usually got closer to 4 hours which is a bummer but still reasonable. Main issue is the screen off battery drain on nougat. Seems to want to drain 8-10% per hour no matter what I'm doing most days.
It's ridiculous. I've drained my new note 5 in 2 hours SOT just browsing Web and reading this forum. I've got 4-5 hours of browsing with my old note 2. That's just crazy low. Xiaomi MI max 2 can easily give you 8 hours SOT. Thinking of exchange already :/
I don't understand how it is possible that every big review on the Internet that I found claims it is more than 8 or 10 hours of Web browsing possible on note 5! How can it be true? Some tests on YouTube shows there is only 4 hours from 100 to 0 without heavy cpu and network utilisation and just screen on...
I consider myself as a Power user. I Only get 2:30 hours no matter the screen resolution, 1080P or 2K. Nougat or Marshmallow doesn't matter. But I'm OK with that, I have a lot of apps and 3 Gmail accounts so I'm getting notifications all day long.
Oh man flashing the n fuel xl Rom was probably the best thing I've done with my note 5. Sot is still lingering around 3 hours or less but stand by time has literally doubled. Now when the screen is off, the phone actually chills out and doesn't burn up battery.
Went from 12-13 hours to 25-26 hours with my normal usage.
new note 5 user here
after reading many of your comment guys, i feel really lucky
i had a note 2 for more than 4 years (still have it) and with my average use i usually get 3.5-4 hours of screen time on
i just bought a note 5 like a week ago and i'm getting more than 6 hours of screen time on
i use the powersaving mode on "mid" and i usually dont need more than a low brightness ... i dont use my phone for games that much cuz i have a ps4 for that ... usually use it for social media and these stuff
i know its very good only bcuz i just got it but with my experience on the note 2 i will try not to drain the battery life and keep it good
note is just the best there is

Oh can you show me a link to the Rom? I am not a heavy user so about 2h sot is fine for me. However I need my phone to be able to last longer while in Standby. I get only 11hr of the phone, including 2hr sot now.
My note 5 battery is dropping >10% per hour with light use. SOT guesstimate to be about 3 hours. Standby drain is great but not when I start using it. Such battery drain defeats the purpose of a smartphone. I guess Samsung has a reason to design the phone with irreplaceable battery. Ordered the S8+ as replacement.
I was studying my battery life/SOT today. I managed to take some screen shots when my phone was around 8%. I'll upload them a little later when my phone is charged up. I let it drain all the way to try and calibrate it. I notice it shut off today at 2%. Around 8% I noticed my screen on time was over 5 hours or higher. Can't recall now the exact number but it seemed unusually high. I think I got around 10 hours of battery life. Once I post screen shots later can someone tell me if they seem accurate and if I get good battery life since I just upgraded to Nougat?

True. Irrespective of MM/Nougat, there is not much we can do about SOT. The best case can be just above 4 hrs. I am on PureX ROM of Rajeev. Between FuelXL and PureX, the best part is on Deep sleep. When the screen is off, the power consumption is close to Zero. The only reason appears to be that both the ROMs are heavily debloated. Any further major improvement to battery life of Note 5 can be only with Oreo ROM. In my Oneplus, i flashed custom Oreo ROM and the battery life is dramatically extended. So, lets wait and pray for Oreo form Note 5.
So everyone on stock N gets around 3-3.30hrs of sot. Felt relieved to read becoz i was worried and thought mayb my phones battery has loosen its capacity.
Btw is there any app that can tell us exact wear level of the battery?? I tried googling some apps but none gave me the exact info that I needed.
I thought my battery was still bad even after changing it but I'm getting well over 3 hours of screen time so it looks like I'm all good for now
I have 4.5-6 hours SOT every day. I'm on stock N, GPS, wifi, sync and lte on all the time. However, every now and then I make a cache reset in recovery, always after a new app installation. Guess my system is quite clean. Battery life is awesome om this device.

Before I sold my Note 5, estimated the battery wear with AccuBattery.
I recommend getting LG V20, its a great upgrade to the Note 5.

No way you're getting 4.5-6
The Note 8 promised long battery service life, that is, high maintenance of original charge. Samsung promised that after a year, the battery would still retain 95% of its original capacity. Using Accubattery, my Note 8 has achieved this. This is vastly superior to what I experienced with the battery on my Galaxy S7.
I don't know much about batteries, but from owning Thinkpad laptops, I know you can get long service life from a lithium battery by deliberately not allowing it to charge to 100% of rated capacity (this is a setting in the Thinkpad battery firmware, accessible from Windows or Linux). If this is the same way that Samsung did this, it means the Note 8 battery has more capacity than it reports. (3300 mAh), achieving long service life by undercharging. This would mean that Samsung gets weaker reviews since out of the box it offers less runtime, but owners get the benefit of sustained runtime compared with previous phones. A pretty courageous move, if my speculation is true. The other possibility is that the Note 8/ Galaxy 8 has some very high spec battery technology which is significantly less exposed to typical capacity degradation.
So now, the Note 9 has a 4000 mAh battery but with almost no change in dimensions, which is curious. Is Samsung still claiming the long service life that it claimed in the Note 8/ Galaxy 8 generation?
I would like to know the answer to this as well.
The device is thicker and wider and 700mah isnt THAT much more physical size wise. But why wouldn't their claims on battery longevity still hold up?

I actually didn't find the same situation to be the case on my S8. I found that at new, the battery could pull close to 6h SOT, and after 500 cycles or so (checked with Phone INFO app), it was closer to 3.5-4h. Not that 4h is a bad figure, and it was still fairly respectable, but it is not 95% retained. Same for my mom's S8, at first was doing 6.5-7h, and now is pulling closer to 3h. I got my battery replaced under warranty at the 1 year mark, but my mom hasn't and it's starting to show.

It might be a bad software update. My Note 8 battery started to suffer until I upgraded to Oreo. Maybe some thing to do with refreshing the battery meter.

Have we seen any official documentation of retaining that 95% battery in Samsung product webpages or leaflets/warranty information??
It was all about official "Claims" for the S8/S8+/Note 8.
Samsung haven't made the same "claim" for the Note 9 yet. Probably will, without mentioning in any official documentation/product pages.

Yeah, it wpoould be best if they included 5.000mAh but 4.000 mAh is still acceptable.
I'd like to know how other's batteries are holding up. I've had my 9 for a month or two now and AccuBattery Pro is showing my battery health as 97% (3882mah) already. I'm not sure how reliable that app is for that stat, but dropping 3% already kind of has me irked a bit.
The only thing i have noticed is when my s7edge and s8+ got oreo my battery life on both those devices was no where near when i first got them. As for my note 9 the max SOT i have gotten so far is 8 hours and 12 min in QHD, i was sitting at 11% battery before i plugged it in.
I have the Mate 20 Pro and it absolutely smashes everything out there. It has outstanding battery life

There was a semi big debate about this on this forum. Accubattery Pro doesn't apparantly show the correct figure from the get go. I'm assuming you didn't use Accubattery from day one to show the before health stats to current? I say this because from day one mine showed 97% health or lower.
Aida64 app also shows the battery capacity at below 4000mAh from new. Hence why Accubattery doesn't show 100% health .
Either Samsung has not implemented 4000mAh batteries in many devices or they are designed in such a way as not to show their actual values in apps.

My Note 9 is 5 days old, and Accubattery says 94%. It's nonsense.
So basically AccuBattery on the 9 is only really good for the charge alarm it sounds like. That makes me feel a bit better. Either way I get great performance so I'm pretty happy with the phone. I normally get between 8 and 10 hours sot so it blows all my older phones except my Note 4 with 12000mah battery out of the water.

Those apps are just estimating. There is no hardware components for such accurate power usage observation in the phones to tell you exactly how much the battery degraded/hold in the first place. Don't trust them that much + battery life in long run is not affected only from the battery degradation, but also from updates and not least important - the applications themself that becomes heavier with every update = the CPU/GPU scales higher and that needs more power and thus shorten the battery life.
Simple example, my HTC M8 eat for breakfast every app back then when it was released. Messenger? NP! Facebook? Lol, 10% CPU usage. And so on. Nowdays it will still run all of those fluid and fine, but instead of 1500MHz 2 cores for example, will use 4 cores at 2000GHz. This affects power usage when it's all apps basically. So it's not just the battery degradation.
That should sum it up about the topic.
My note 9 is also around 94% battery since day one. But this was not the case with the Note 8. I was at around 103-105% battery capacity on the Note 8 for a long time.
It is an estimate and not perfectly accurate but Samsung does have the ability to measure battery wear.
On jailbroken iPhones you can get the exact wear percentage and now iOS has battery wear shown directly in battery settings.

Hello, I'm a new user on xda (but actually a longtime reader). I finally decided to upgrade to Nougat with OTA updates. My device works perfectly fine, except for the battery. I have another android running rooted stock Motorola nougat with similar apps and usage and able to survive until midnight with 15% battery left on on medium use, while my Note 5 can't even survive half a day on light usage.
In battery usage stats, most battery use percentage is the screen, followed by device idle. I don't use LTE with hope it can help, and using 720p resolution to see wether it can also help. The screen on time lies around 3-4 hours but the standby drain is very annoying.
My device has never been rooted. I'm considering flashing a rom if it can help the battery issue, but I use the S-pen a lot and don't want to lose its functionallity by using a rom without the S-pen apps. Right now I'm considering flashing a ported version of Note FE rom by RadeonMaya. Is it good for these purpose?
Any idea on what to do?
The Note5 is over 3 years old, don't expect good battery life. Even when new it was bad. 3-4 hours of Screen time is A-W-E-S-O-M-E. I only get 2 max.

Thanks. Perhaps i'll consider buying a battery case or something.
Get the battery replaced. I did mine myself and it's like a new phone again
So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.
Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".
Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.
I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.
I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.
Get Karma Firewall and a package disabler like this one;

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.
You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!
SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).
Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.
Is this on the snapdragon or exynos variant?

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.
My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.
Hi folks.
Aight m11 battery is pretty horrible ngl.
I got my m11 with miui 12.5. 1st day I got it battery dropped to 40% within 5 hrs with 30 mins sot.
I was sad phone trash.
Next day was better but very buggy battery still drain not as bad was at 60% after 5 hrs 1hr screen time.
Next couple of weeks playing with it.. Trying to figure out better battery usage but why should I its a flag ship phone?
Battery was still very buggy sometimes drained 20% over night sometimes it was fine. Got miui 12.5 enhanced slight improvement.
I got all excited waiting for miui 13. 1st impression very good. But battery life sot averaging 4.5 hrs 100% to 5%. Idle time very good too.
But now I got oneplus 10 pro. Yes oneplus had extra 500mah but I get more battery out of it ngl. Whole phone is better and I use it the same.
So my question is it the cheap hardware xiaomi use like battery for not so OK sot.
Or is it the software? Because miui 13 hella improved battery life and is very stable compared to 12.5.
And the roms on here will they have noticeable better battery life? People should know the difference between miui and own roms sot. I'm tempted to try it
I have a few months old Mi 11 Ultra with miui 13 and I am experiencing the same problems...
I think it combination of bad battery and software.
The 20% drop at night is a sure indication that something is running in the background... that probably doesn't need to be.

Yes it was random sometimes did sometimes didn't. Yes but miui 13 fixed idle consumption.
My oneplus 10 pro 96% battery life 40 mins sot put it that way. And 80% is when the battery drains the least
Yes my brightness is at 30% inside now. But my battery still alot better. But I don't understand why some xiaomi phones have great battery life with same spec as other phones but not the Mi11?

Most Samsung phones need to be optimized for best battery life.
Xiaomi's likely has to be as well. You need to find the power hogs and deal with each on a case by case basis.
Using manual brightness control helps save your eyes and battery.

I have auto Brightness on hence 30% brightness inside. And I looked on my battery settings and nothing was running on Mi11 I've done nothing to my one plus 10pro and battery pretty good for a flag ship

It's may well the firmware or factory loaded software. However it could be 3rd party apps misbehaving. Google apps tend to cause battery consumption troubles...
Android give you a lot of freedom to configure them the way you want. Cookie cutter Apples doesn't so it's easy for Apple to optimize their products. So with Androids the end user needs to pickup the slack many times and find work arounds or setting changes.
Yes but even if I use my phone straight off charge its still roughly 6hrs sot indoors (no sim) WiFi only 20% screen brightness. When I used it outdoors with sim 4.5 hrs if that . So I don't think non sleeping apps where doing it. I look on my battery usage and it says my apps used 3600 mah battery including screen with 25% battery left with 4.4hrs sot. So no mis behaving apps.
It might sound good but my screen brightness super low

You need to see how much each app and service are using, then figure out why. It takes some time and effort to track them down... a learning curve.
FB, WhatsApp, all social media apps should never be installed on the device. If you can't access them using browser login, forget them. They are nothing but trouble...
Yes bro I checked had enough of mi 11 no apps causing trouble checked for months.
Idle consumption very good lose 0% over night sometimes. I thought miui 13 would have substantial battery increase but only fixed idle consumption.
I thought maybe they would optimize battery usage better like Samsung 21 ultra.
My oneplus 10 pro is on 2hrs sot with 40% brightness and 84% battery life. Very good battery life no need to worry bout it dying when I'm out
Its not me thinks mi 11 battery trash too 90% reviews say to and GSMarea gives it a rating of 84hrs and the one Plus 10 pro 104hrs battery endurance
Now back to my original question is it xiaomi cost saving software optimization trash or battery hardware cheap?

You won't know until you work with it more trying to optimize it.
This Note 10+ was a hot running battery hog until it was optimized. It gets 7-8% @hr now when browsing with Brave. It took months to finally dial it in. Over a year to really get it right.
A lot of work. My second N10+ was a snap to optimize as I knew what to do.
One thing I do is not to upgrade firmware* or app updates as this can start another cycle of trying optimize the new firmware/apps. I'm running on Pie and Android 10, malware is not an issue.
*if I have a fast, stable OS... I let it be!
R u serious. What do u mean optimize? Putting apps to sleep isn't really optimizing.
Ur trying to improve battery when only really the developers can fix it.
Yes putting it in dark mode 60hz putting everything to sleep not running nothing fun having brightness on 0% will improve battery life but experience will be trash.
My oneplus Pro 10 is out the box restored all my data whatsapp 3 emails with sync on 4g nothing optimized. Screen brightness normal too (I want a good experience)
battery optimization or battery hardware is great. The layout skin in oneplus 10 pro its faultless too and looks alot better than xiaomi.
Other hand is xiaomi mi11 definitely a cheap battery or lazy developers to cut costs hence the price but one plus 10 pro is same price. But other xiaomi phones r very good battery life so I'm confused

Global power management never worked for me, disable it and deal with each power hog on a case by case basis. Limiting background data/battery usage in individual app settings doesn't invoke global power management.
Some apps like Brave browser need to be closed after use or they continue to run in the background. I disabled Google play Services unless needed. I use a package disabler to kill anything bloatware or other apps/services that cause trouble and aren't needed.
I never said it was easy... there's a steep learning curve.
Dependencies; disabling a parent app/service can have far reaching consequences, good or bad. Try to understand what you are disabling.
Acquire or use the already loaded the tools you need to help find the trouble makers... play with it.
Definitely ****ty software, battery backup is much better on AOSP-based ROMs.
