[Samsung Galaxy Note 9 Real Life Review] Jammol:
Why is SOT a category when it's relative to each user specifically? People, stop basing your SOT with someone else's. It will never work out the same or even close to each other unless you live in the same area, go the same places at the same times while using your phone's for the exact same things at the exact same times.

All of you SOT experiences will be different. Some as much as hours.

Exynos version, WiFi 80% LTE 20%. Location Bluetooth only when required. No AOD. Started charging when battery was 47%.
[Samsung Galaxy Note 9 Real Life Review] high_voltage:
You should try with full CPU speed and qhd+ resolution. For the resolution - the battery difference is super small and from my testing even non existent (the GPU is powerful enough to not care for basic image what the resolution is set on and you can play youtube videos on fullhd instead 1440p if you want :) ). As for the CPU limiter, it can actually hurt in some cases as the CPU will have to run longer to finish the task + snapdragon 845 is acknowledged to have great CPU/SOC control leading to using only what is needed. I am pretty sure you will get the same result or better with CPU limiter off and almost certainly the qhd+ will not make any real difference outside the statistical error.

---------- Post added at 05:52 PM ---------- Previous post was at 05:41 PM ----------

24+ hours on battery, 12h SOT, autobrightness on, mixed wifi/4g, no power saving at all, QHD+ resolution. Usage: samsung browser, youtube, messenger, facebook, viber, few pictures, listening to music with screen off via poweramp (it's a heavy player), light games, etc. I have the exynos 9810 variant. I get 6h only if I play for 3-4h heavy 3d games (like fortnite, vainglory on high gfx, etc). Otherwise 10h are easy, atleast for me - it will vary from user to user as we all use our phones differently and the only real comparison one can do is to use both phones.

This is just my experience ofc, I still didn't try the mate 20 pro, but I am sure it will get a great battery life too.
[Samsung Galaxy Note 9 Real Life Review] gamekill:
That sounds really great and I am gonna try it out BUT, why would Samsung leave this on in the power savings then? Only for extreme usage cases? i.e. if I planned to play Fortnite or some CPU-intensive game for hours?

But then again, they should not include the CPU limiter in the average-user-centered "Battery Saver" options. They could put this CPU Limiter option in their game-centric app (forgot the name.. Game Center?)

Also about the Mate 20 Pro.. yes me too, I think it might perform even better in relation to battery life. But, the Note 9 is great for everyday usage as it is. Maybe next time I will go back to Huawei who knows. Or not lol. Can't tell the future.
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
I personally prefer Huawei over Samsung
[Samsung Galaxy Note 9 Real Life Review] high_voltage:
Same, we will see in the future. For now I am good with the note 9. As for their reasoning - they have unified software and are really careful to not make differences that will cause the media to go "both variants are different!". The power saving is more efficient and noticeable in the exynos variant, but even there the benefits are in certain situations and usage - i.e. if the phone is used more heavily like multitasking, 2-3 apps at the same time, etc, it will use similar power CPU power saving on/off while giving less performance. My advice is for the fellow xda members to test it for day or two and see how it goes with unlocked CPU speed. Cheers mate! :highfive:

Edit: as for their reasoning about resolution by default to FHD+ - it's mainly to play youtube videos by default to 1080p instead of 1440p and if some lighter games are drawn directly to the native resolution - to be 1080p instead of 1440p. The game part is rare or doesn't really matter as the game is too light anyway, the first youtube one is something the more advanced xda member has control at and knows easily how (the basic users most likely never change the auto setting). The UI itself is not draining a lot more battery if any at all @ 1440p vs 1080p. Really, tested that many times on my s7e and I feel the UI even smoother on 1440p vs 1080p + a little bit sharper (as expected). So I would give that also a try. You can also divide - one day change the one option, second day the other and 3rd both. To see how it goes.
[Samsung Galaxy Note 9 Real Life Review] Virgo_Guy:
Exynos.

With Build no "ARJ7" (with October. Sec. Patch) , batterylife is little better/on par with the August's "ARH5"(with August sec. patch) . Build "ARJ1"(with September Sec. patch ) was giving low batterylife.

*Settings, apps and measures same as my old post on "9th September" here + AOD on for specific time.
[Samsung Galaxy Note 9 Real Life Review] gamekill:
I started to test usage with the power saving set to off. Still too early to tell, but I guess I will get marginally lower screen on time (will test for some days, some charging cycles, to be sure).

BUT what I already noticed is, unexpectedly, my standby drain (during night) was better with power saving disabled. With power saving on, I get good battery life but the small (but noticeable) battery drain overnight was annoying me. The line was around a 2 degree steady descent for 7 hours or so. Now that I disabled power saving the line is only tilted around 1 degree, or I don't know, negligible drain.
[Samsung Galaxy Note 9 Real Life Review] serkodzhanic:
I'm using now note8 phone (which gives me around 6 hours SOT) and want to upgrade to note9. what will be est SOT with 1-2 hours of youtube, 1-2 hours music, 1 hour gps navi and 1 hour web browsing per day?
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Bigger batteries will obviously lost longer. How the two phones are each configured will affect things further of course.
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
The battery size difference between the Mate 20 Pro and Note 9 is 200 mah however the difference in everyday usage is quite substantial. So please don't make that bigger than what it is
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Apples and oranges without considering relevant factors like screen brightness, app configurations, screenshots, etc. It's not bigger than it is, just observations for more relevant, consistent, and therefore more useful comparisons :)
[Samsung Galaxy Note 9 Real Life Review] vwite:
First sentence is not necessarily obvious or true, with my usage (comparing apple with apples) the Note 9 averages 5 hours SOT while the Mate 20 Pro averages 8 hours SOT, so let's say the Note 9 was the one with 4200 mah and the Mate 20 pro was the one with 4000 mah, then the Note 9 would be the one with the biggest battery, yet it would last 5.25 hours SOT and the Mate 20 with "smaller battery" ~7.62 hours SOT

And yeah, there's people who can get around 12 hours SOT with the Note 9 watching offline content, barely using SoC and, and using low brightness or black backgrounds with a lots of pixels off, but then the Mate 20 Pro would last ~19 hours SOT in that same scenario
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Samsung Note9 have a chip on 10nm and battery 4000mAh but Mate20 have a chip on 7nm and 4200mAh battery,so Mate has a clear advantage. I can not see why to compare it with Note9. Mate20 should be compared with S10.Samsung Notes on its segment is unique so it has no rivals.

---------- Post added at 08:41 AM ---------- Previous post was at 08:38 AM ----------

And if I look at some battery tests Samsung Notes is even very good, even with Mate20. Everything depends on user, settings, programs, signal, ....

Can you share the adb debloating steps for Note 9 Exynos?
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
The Huawei P series is comparable to the Samsung S series and the Mate series is comparable to the Note series.
[Samsung Galaxy Note 9 Real Life Review] high_voltage:
I get to 12h SOT with normal usage on my note 9 - no power savings, high accuracy location, mixed 4g/wifi usage, 1440p+ resolution - facebook, messenger, viber, samsung internet browser, youtube, 1-2h music screen off, 24h on battery, etc. That said, it's totally possible for me to get a lot more of the mate 20 pro. I remember how I had 7-8h on my HTC M8 while the most got 4-5h. I optimise my phones, even when stock. The only people that can somewhat objectively comment on battery life between two phones are the ones that used both for extended period of time.
[Samsung Galaxy Note 9 Real Life Review] Cristi10:
I've had both the note 9 an mate 20. It's the same as with s9, while using it prolonged, it's relatively ok. But stand by it's just not great and while doing heavy stuff, like maps or 4g streaming it's not impressive. On mate 20 i have better signal and it's just can go on all day, and i should not mention the camera. I kinda lost faith in Samsung, for so much money, Samsung has become sub par
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
That's why the post should be read in full, as the second sentence qualified it ;)

Thanks
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
İt didn't mate. First sentence is definitely useless
[Samsung Galaxy Note 9 Real Life Review] sefrcoko:
Lol sorry you think so. Just saying bigger batteries last longer than smaller ones. And regardless of battery size, you need to factor in brightness, apps, usage, signal strength, etc. for a proper comparison (which many do not do). If you disagree with that, then that's your prerogative I guess. You can get the last word if you really want it. Cheers mate
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
İts not about getting the last word. Bigger batteries last longer doesn't always apply. Also with the size difference concerned we are talking 200 mah. However the difference in real world usage between the two phones the difference is more like 1000 mah. The Mate 20 pro lasts way longer. Yes you can argue Mate 20 pro has a larger battery but in reality there is more to it
[Samsung Galaxy Note 9 Real Life Review] michelino159:
Everyone is talking about batteries but nobody says anything about the processor. A 7nm processor can be at least 30% more energy efficient than a 10nm processor, and if you have a bigger battery then it's great. I did not see a notable difference between the two. Just advertising.

Please,stay on topic!
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
You didn't see notable difference? You said a 7nm is upto 30% more efficient compared to a 10nm. However didn't see any notable differences. Hmmm hard to believe.
[Samsung Galaxy Note 9 Real Life Review] michelino159:
When Note9's battery is on 0%, Mate20Pro still has 10% in the same mode of use. So bigger battery, better processor but only 10% difference. I think it's not a noticeable difference.

[Samsung Galaxy Note 9 Real Life Review] skabt:
my note 9 battery drain on stand by is bad. 8 hour sleeping time it drop 10-15% (stock and nothing ON, cause N9 is my desk phone now), max screen on time i get is 5 hour > with wifi connect full day. btw i does claim battery warranty after two week N9 preorder delivered/
[Samsung Galaxy Note 9 Real Life Review] OJsakila:
It's all relative, guys. Your apps installed and screen on time usage are definitely not the same I use and have installed. Period.

Unless your phone has a hardware defect I would look at your apps.... I had a note 8 and I'm finding lots more battery power compared to my Note 8...i stream howard stern every morning for 4 hours and I I'm left with 90%. On my Note 8 I had about 80% or more after the exact same behavior.... I'm 100% happy. Stats and what not don't mean sh*t to me
[Samsung Galaxy Note 9 Real Life Review] cavags5:
you are saying 4h screen on time with 10%, on wifi?
[Samsung Galaxy Note 9 Real Life Review] OJsakila:
No wifi. Cell data. And that's streaming Sirius
[Samsung Galaxy Note 9 Real Life Review] michel333alfa:
They might increased CPU usage for better performance in ui
[Samsung Galaxy Note 9 Real Life Review] cavags5:
you are on stock rom?

even in wifi, or with downloaded movies, and played in samsung video app, never did more than 2h on 10% and depends on the brightness, and with the note 9,i have my phone stock and optimised, and its impossible to reach that, never seen any post like that in any thread.

so you are saying you can reach about 30h sot in 100% battery?

Don think so.

Please share some screenshots.

Thanks
[Samsung Galaxy Note 9 Real Life Review] Hazzay88:
Man you don't expect anyone to believe your **** do you? I would recommend you showing stats and evidence rather than coming up with all this garbage. No one will fall for what you just said. Forget the Note series not even the Huawei Mate series can achieve that. Which planet are you from
[Samsung Galaxy Note 9 Real Life Review] OJsakila:
Hey, don't be a jerk. I was merely saying what I've experienced with my Note 9 which is about 10% better battery life. IT WAS A COMMENT NOT SWORN TESTIMONY IN A TRIAL. I don't give a f**k what you think. You're definitely a jerk.

Yes it's radio or TV channels.

But its not available for my country.

Only in apk.

But if is radio with screen off its another story.

But leave us a screenshot of your daily usage, the thread is for share users usage.
[Samsung Galaxy Note 9 Real Life Review] vwite:
Yeah I don't use it either, I just googled it but it's obvious he cannot do 4 hours screen on time streaming video, even if it was lowest brightness so it must be just audio with screen off and I assume plugged headphones. I stream a lot of audio (YouTube Vanced but background playing, screen off) with IconX 2018 Bluetooth earbuds and battery life is not so great
[Samsung Galaxy Note 9 Real Life Review] high_voltage:
I tend to not use my PC at home + do some work on the go from the phone, otherwise the 12h are actually in more than 24 hours or are cases with 9h SOT and 30% battery life left = projected that I will get more than 12h SOT.

Everyone is different, I had every time 8h SOT and 2 days of my HTC M8 while a lot of people got 3.5h SOT and 12h battery. ;)

My settings are a lot to list, but a lot of things can affect battery life - auto backups, sync of useless stuff, rogue apps that use battery, unoptimized apps that collect and send data/run on backgroud/autoupdate themself and the updater is constantly loaded into the memory (say hi to facebook and messenger apps, check their settings :) viber also got collecting data ON by default, same as tons of other apps), constant GPS use, constant camera use, heavy 3d games, etc. My usage is primary a media consumption, social, browsing, 1h avrg per charge music listening and some gaming (heavy one tho, vainglory on high). The 10-12h SOT are if I exclude the gaming part (that makes it as primary apps: facebook, messenger, viber, samsung internet browser, youtube). Otherwise I got wifi in home and work, using 4g + data between the two places or if out. Autobrightness is on. Yes, I am sure I will get easy 10h SOT as constantly I hit 5h SOT with 24h and ~55-60% battery left and on the note it doesn't discharge a lot faster when <50% like on some other phones. Few times I really did hit over 10h SOT and two 12h SOT.

Not like some snapdragon members tho that hit 14h+ SOT ahahha, but I don't try to win some race and I am happy with the overall experience. The battery life is a lot better vs the s7e with goodly aged battery (still easy to hit 5-6h+ SOT and full day on it).

---------- Post added at 10:40 AM ---------- Previous post was at 10:34 AM ----------

Actually this is only partially correct. The new nm process saves some battery, but:

1) it's not true 7nm, i.e. it's referencing only to the space between the transistors, but the transistors themself are on 10nm. The benefits are not that great compared to a true 7nm

2) The phone makers manufacturers always states - up to 20% performance/ up to 30% less power for the same performance. This is marketing as it's either the first or the seconds or balanced combination of the two. It's not 20% faster and 30% less power consumption. That power consumption is only about the same perf not the scaled up every generation one. There are savings, but not that great.

The last part is totally correct and you observed it - no notable difference and advertising. Cheers.
[Samsung Galaxy Note 9 Real Life Review] cavags5:
I see you know your phone, I know I that too, but, I use 4G all day until get home, I have most of the apps disabled don't use Google stuff, sync is off for every backups, only turn on when I'm in home.

I use app mymail to get my emails, without sync on. all apps I don't need notifications are always optimised, Facebook messenger WhatsApp Instagram are not, I need them, some others are off in the background,.

I don't use GPS, only when need it.

don't play games,.

I see YouTube, some series, take notes, do budgets, edit some things, some pictures, and emails.

note 9 of all samsungs have the best battery until now, but, not that difference.

10h sot is possible to do easy in more than 24h but at home with wifi,

outdoors brightness can be a battery drain, I use auto, because of the sun. and use Bluetooth with my car all the time.

I can get, 3 to 4h until 50% depending on the brightness.

I get home with around 40% 30%, then wifi, I usually charge it with 20%,

I know if I turn 4G only when need it, the phone last way longer, but all my tests connection is always on..

signal could affect real bad the battery.

about the 7nm processor, I know that's all marketing, but I have to say, I like note series and will not return to the S series again, but after I tried the Huawei mate20 Pro, that is a very noticeable faster performance, from note 9.

since s8 s9 N9 I don't se that difference, overall I prefer the Note.
[Samsung Galaxy Note 9 Real Life Review] high_voltage:
Keep in mind that I found that disabling apps can affect in a negative way the battery performance on samsungs (not like that on, for example, my HTCs). Better leave the all on, the android system will auto sleep them when not used for a 3 days.

It's correct that the signal affects the battery quite a lot, also while I am using mostly wifi, you are using mostly 4G. On top of that I don't turn on bluetooth while you use it and for a finish I rarely use my phone in direct sunlight (rarely to check some msgs, nothing more). Even those are enough to lead to a massive difference.

The mate 20 SOC cpu part is just that much stronger than the exynos part (it's not about the 7nm process, it's about the architecture/cores used and so on). Samsung really did poorly with the M3 cores/exynos 9810 + it's control that is mostly bad because of flawed hardware design. Even the sd845 wipes the floor with it except in geekbench single core test - real world, other tests are a win for the sd845 (CPU, the GPU of sd845 is 25-35% faster depending on the workload). The new huawei SOC is targeted to the new generation, i.e. sd855 (will not be called like that tho), A12 and exynos 9820. The exynos 9820 shapes to be nothing special, the sd855 will be a lot better vs both kirin and the exynos, but still behind the apple's A12 in CPU, the GPU will be a close call and more about sustain perf war . All that said, that A12 SOC makes all the others look like a joke, but sadly it's under-utilised because of the OS - still, it will be the leader perf/efficiency SOC again till A13 and what SD/samsung/huawei will bring in 2020. :)

Also I forgot to mention, changes take place immediately, no reboot required. I am not 100% sure if it goes like that for everything but I think so. So for instance, I could not access the Battery Usage graph because I disabled the package, but the instance I enabled it, cables still connected and all, it was accessible.

This makes it much easier for testing what you do need enabled or not.

My screen on time seems pretty underwhelming compared to some of what I'm seeing here. Do things like leaving Bluetooth on or using Nova launcher make a big impact on this?
[Samsung Galaxy Note 9 Real Life Review] picia89:
Hi. There will be always some hidden secret behind the SOT >=6h.

I tell you mine.

1. There is an Autumn in Poland, so it is darker outside. Screen brightness is never > 40%. Usually less.

2. When I go to the work I browse internet but since this is early morning, I still have the dark mode enabled on Samsung Internet browser.

3. I changed the way that I browse the Internet. Before I scrolled the page often. Scrolling always set your CPU on higher frequency. For me this is more convinient to use Spen and click on it. It scrolls the whole page, not line by line what I was doing before.

4. I have power saving on but limited only to CPU 80%. Anyway it is smooth, so no difference for me.

Don't believe that if you disable everything you'll have a 12+ SOT. It is impossible. What matters :

- Screen brightness

- CPU usage

- Network signal strength (weak LTE/3G will drain your battery).

- GPS in use (if it is just enabled, you will not notice a big difference).
[Samsung Galaxy Note 9 Real Life Review] Reno95:
It's crazy how some exynos users are getting at least 7 hrs of SOT. In my case, whether it's light or heavy task, I always get a solid 5hr sot with or without battery saving. I'm starting to think that there's something wrong with the SOC itself. Can a samsung moderator see my comment?
[Samsung Galaxy Note 9 Real Life Review] guthrien:
I still find 7hrs to be unlikely without being careful and settings today are conscious of battery loss. Which I would do in a danger situation. I got awful battery when I got this phone, 3hrs SOT etc. I wiped it and now get 5+ with everything full bore. To me that's very satisfactory with almost 2 days off usage.
