According to the review from The Verge, Transformer Prime loses out in battery life to iPad 2 and other competing tablets and is only marginally better than iPad 2 when the keyboard dock is attached.
I find this very disappointing, I did not expect Asus to announce their battery life with the device in its lowest setting, while iPad 2 gets eight hours of battery life in 'normal mode'.
5 hours is very, very low. I expected them to at least match iPad 2, especially when they announced that it will survive for 12 hours.
The Verge review is by far the lowest of any of them. Several report 10+ hours when playing video. Anandtech has 8 hours with an apparent mixed load.
It was advertised as 10:04 on Balanced, the default setting. That review uses Normal, where the two power-hungry cores are always active, instead of shutting off when they aren't needed.
Check out the bolded "NOTE:" where they say they're rerunning the battery test. Engadget said it lost to the iPad 2 by only 9 minutes on Balanced.
EDIT: And, according to the comments, this is without discharging/recharging the battery - battery stats aren't calibrated yet.
I think 5 hours is just for the dock and 10:17hours (according to engadget) for the the tablet...a total of whooping 15+ hours, not BAD at all
No, the review on Engadget said that they expected 15+ hours with the dock.

No, they cannot test how long battery lasts on the dock alone. The Verge found that it survives 10 hours with the dock.
Balanced mode or not, fact is that iPad 2 is rated being in 'normal' mode for more than eight hours. Prime in normal mode only gets 5 hours. They may advertise their 'balanced' mode, but that is not as good in performance according to the review. In fact, the whole quad-core for tablet is put in doubt, it doesn't make the interface (and browser) faster at all, it only seems to help with games.
I am disappointed.
I'm impressed as this tablet doesn't need to run in normal mode 24/7, meaning 4 cores on all the time. That'll be a waste when balanced mode alone makes it as snappy ,if not more than ipad2. This still has the best battery life of any android tablet I've seen. All sites I've seen that reviewed it are very impressed with battery life. Plus the source you listed isn't as reputable as the main ones churning out the praises on battery life. Instead of just taking that one review and making an assumption, compare all of them. Seems strange that one site out of several giving it negative battery comments. As it's also strange you being disappointed already on an assumption from a sub par tech review site..lmao.
Get an ipad2 then while we blow past ya with the excellent performance and battery life of the prime.

Well, you won't. iPad 2 has a better GPU and does not need a 'balanced mode' to have a battery life as long. iPad 2 gets 8 hours of battery life in their 'normal' mode that only lasts five hours on Prime.
I am still going for Prime, because I'm Android developer and my phone is an Android, but I was hoping that Prime would have battery life longer than devices released six months ago without having to tune down the performance that makes it fast.
Now it is a trade-off.

I think you missed the point of what he was trying to say. The site you are quoting your stats from in regards to battery life was the only one that rated it low in that regards. Let's take engadgets review for instance which on "normal" mode lasted for 10:17 which was 9 minutes shorter than their iPad 2 test. So the idea was if placed in "balanced" mode it would get longer life than its already good life.

iPad 2 gpu has more raw power but not the resources to back it up. There are hardly any ipad2 only optimized games out. Most stuff I can still run on my ipad1. I don't think Asus never claimed 12 hours battery life with 4 cores running at once. I never assumed that either. I see what you are saying though. Just compare the different battery reviews. Plus battery wasn't even truly calibrated yet. So it'll get more than 5 hrs. In normal mode. You have to remember to we talking about apple, the king kong of tech..lol they have the money to be lit years ahead of the game. That's why my ipad1 still performs great for me although it's clearly not the highest spec tablet out now.
The go out in get an ipad2 was just a joke. Android is getting closer and closer to closing the gap on quality and performance with iPad. This Asus Transformer prime is what will start the next wave/revolution of high tech tablets and Android in general. I've been thinking also about those different power modes and display modes of which I would use the most. Seems like the balanced mode does well without noticeable drop in performance since it uses amped up dual core. I would think normal mode only needed for intense gaming or very resource hungry apps. We will see once it comes out. Regardless, this will be a great price of machinery at a lower price entry and higher gb storage than ipad2.
Anand review reports 9 hours and Engadget reports 10 hours battery use....both tablet only..
either the unit the Verge got was faulty..or their battery test was significantly different
What is this Prime "normal mode" and "balanced mode"?
I know what they are, but is there some kind of a "switch" to choose between normal and balanced mode?
An option in the setting?
I thought the Tegra 3 will determine this 5ft core functionality (when to use) automatically.

Asus implements 3 different settings for the Quadcore, this is from Anandtech.com:
There are three power profiles ASUS and NVIDIA have defined on the Prime: Normal, Balanced and Power Saver. Normal allows the CPU to run at up to 1.4GHz with only a single core active, and 1.3GHz otherwise. Balanced is the default setting and it drops maximum CPU clock to 1.2GHz and favors lower clock/voltage targets on the curve compared to Normal mode. Power Saver caps CPU frequency at 1GHz with 1 - 2 cores active, 760MHz with 3 cores active and 620MHz with 4 cores active. It's unclear what the impact is on GPU clocks/performance.

Thanks ... So the difference between Normal and Balance is 0.1 - 0.2 ...
Normal = Max 1.4 GHz (1 core) or 1.3 GHz (2 - 4 cores)
Balanced = Max 1.2 GHz (1 - 4 cores)
Not much different, isn't it?
I would choose Balanced and be done with it.

The mode also determines how the CPU speed scales to meet loads
ie Balanced would be slower to rise to its max 1.2 GHz than Normal
wow op sounds like an apple fanboy, he just keeps ignoring what everyone has to say about the review being the only one to state a 5 hour energy life.
if its only 5 hours i wouldn't buy it.

I do not own a single Apple device and recently purchased Galaxy Nexus in my line of Android devices. I am also an Android developer. Just because I am disappointed by the battery life on the so-called 'normal' mode does not mean I am an Apple fanboy.

both anand and engadget reviews were running Normal mode too...and the batter life rivels iPad even without dock..and certainly the best among all android tablets.

You still fail to accept what everyone else is saying.
But here's an idea: Just get the prime and send it back to where ever you bought if it doesn't please you...
What about checking the battery life YOURSELF before whining here? Good idea?

Are we turning into Apple fanboys ourselves!? Seriously, I can be critical about the device, stop acting as if I don't have a right to voice my concerns or share my opinion.
Of course I will check the battery myself once it's released. I simply expected it to perform better in reviews than it has. This is not just because The Verge shows weaker battery life than devices released months ago, but also AnandTech, where the battery apparently lasts less than iPad 2 as well. I keep bringing out iPad 2 not only because it is so widely known, but also because it is the standard other devices are measured against in terms of application speed and UI.
I simply expected it to blow opposition out of the water, but it is only marginally better in some ways. The quad-core also does not enhance Android experience as has been pointed out, it doesn't make the UI and apps slicker unless in really obvious examples, like a game (and iPad 2 is also great in games).
I am also disappointed to hear that some of the integral things, like a browser, is not as fast as one would expect from a quad-core device. The lags in zooming and moving around have been pointed out in reviews.
And it just outright loses against iPad 2 in processing power too.
So it costs as much as an iPad 2, but loses out in both battery life and performance. It is better in some ways, like the camera, but really, it does not blow the opposition out of the water. It will not be the 'best Android tablet' out there for long either.
I have a 16g black one from Google Play. and luckily it has no light bleed, minimal give on the back but the thing just get HOT even when I am using tasks like watching video or reading Chrome like now. I monitor the Cpu temp and it is around 40 > 50C when watching video surfing the web etc. However, when I am playing 3D games and stuff it get to about 60 > 75C. I dont know if it is normal or not and is this just a software or hardware issue because it get really hot on the top near the camera and both the screen and the metal rim get hot and burn my hands. I am considering RMA it if is cant be fix through a software update though. So is can it be fix through further update or rooting and new custom rom help ? And is a case gonna help reducing the heat to my hands ?
Also if I wait for the next batch can I wait and exchange for a better one then ?

You must be the lucky one the got the special unannounced option !
Only a select few have the New HTC "Hand warmer" edition made just for cooler climates like Antarctica.
Guys, can anyone help ?
This is normal. Any processor heats up with heavy gaming. The nexus 5 (snapdragon 800) can break the 70C mark in some cases. The nexus 7 (2012 with tegra) heats to 60C before throttling. The nexus 9 does try to dissepate the heat as quick as possible (lots of copper) and feels warmer.
Samsung devices are even worse, as they start throtteling even later.
The tegra k1 is a beast of a mobile processor (gpu and cpu).

Basically, this.
Hell, my N5 actually reboots during antutu due to thermal heat and heats up a lot during gaming.
Also, the reason it heats up when watching a video, do not forget a video has to be decoded to be displayed on the screen. Hardware decoding is less intensive but some still rely on software decoding wich will heat up and cpu in a matter of minutes. So even something as simple as watching a video can be CPU intensive depending on the decoder.
As for chrome, haven't had my N9 heat up during chrome sessions. Weird
Actually, the Nexus 9 manages as only Android device in my collection to stay completely cool in netflix HD streaming. 10% battery usage after 90 minutes. Compared to the other devices that use up at least 40% of battery during the same time.
One drawback is the 4:3 screen, which still makes my Note 10.1 beter for netflix (or movie viewing in general)... But the Nexus 9 is the only tablet I even consider using in portrait.
Same problem here, especially with Chrome. I've rooted my device, I don't know if that could have something to do with the heating...
Chrome Beta seems to have really helped with the heat issue on mine. I still get a lot of heat with gaming but that seems to be it.
The n9 was the first device I've ever had that heated up on me while browsing in chrome. This is NOT normal. I RMA'd it and picked up a shield instead... I don't know how these devices passed QA with all the issues they're having.
My personal opinion, is lollipop isn't quite ready and many apps aren't either. I'm waiting for all to be updated. The heating problem will, I'm sure, be taken care of.

Hopefully before black friday . The Sheild went up last year and I'm expecting it to do the same this year, not sure if I should go ahead and buy it or wait for the Nexus 9 to be fixed.

I noticed the other night a considerable warming by the camera area and all I was doing was browsing the Internet. So as I was using Chrome I stopped, and browsed with FireFox, the tablet cooled completely down. Even watching YouTube it was barely warm.
I think something is wrong with Chrome and it's causing a loop somewhere in the code ramping up the CPU causing it to use a lot of power and that equals waste heat.
Playing games also has the same effect, it ramps up the CPU. The CPU is probably rated to continue working up to quite a high temperature before it needs to slow itself down to allow to cool, but when that heat causes the case to become very hot, it should back off the speed and so keep itself cool a long time before it reaches any of it's own temperature maximums, the trouble is keeping the case cool means the CPU can't maintain high performance for very long, so what's the point of a fast CPU.
Really tablets are not the best designed devices for 3D type game playing, or anything really that needs to use a lot of CPU power over and above the occasional burst.
I wouldn't be surprised once all the benchmarks have been done and published, if a software updated doesn't fix the heat problem by throttling the CPU quicker, and running it with realistic performance characteristics that being sandwiched in a very thing plastic case with no vents or active cooling requires.
Regards

I second the chrome beta helping. I disabled regular chrome in app manager and installed the chrome beta and have had a significant boost in battery life and decrease in heat while browsing.

Do you still notice any warmth using Chrome Beta? Or is it relatively cool? I have tried both Chrome Beta and Dolphin, and I am still noticing a good amount of heat. It's actually cooler watching Netflix than it is doing any sort of browsing whatsoever.

Saturday when I switched to the Chrome beta for the first time the heat was the same as before. Yesterday and today it has been noticeably cooler. I'd say the tablet gets just warm enough to notice a difference from it's ambient temperature when using chrome beta. I've gotten slightly better battery life but i'm still only hitting 4 hours screen on time when I hit 15% battery which is about a 1 hour increase from before using chrome beta.
I think chrome is still in need of major optimization because as you said when I use youtube or netflix I get much better thermal and battery performance. I did notice today that chrome seems to be performing extremely well on page loads and interactivity with javascript elements etc. I threw as many complicated sites as I could at it and made sure to go to sites I that hadn't been cached before on the tablet and it was super fast. It actually impressed me with it's performance which I wasn't expecting. Now it just needs to get more battery efficient and it will be perfect.

Thanks for the details. It's a shame that browsing is so poorly optimized. That's my main purpose for a tablet. I've just been on Dolphin the last hour and yep, heat is still pretty strong and my battery has gone down quite a bit. But before that, I was running Netflix for several hours just to test, and was up to about 5 hrs SOT. But I typically don't watch much Netflix, so that doesn't reflect real-world usage for me at all.
Yeah it's a little disappointing but the improvement I saw from chrome release and chrome beta is promising. My browsing experience today aside from heat and battery issues really made me like this device. The performance really blew me away. It felt more responsive than my i7 desktop.

I too find myself getting attached, despite these issues. It's a really smooth tablet experience :good:
Overall I like the phone, but I have a few gripes. Maybe some of you agree, and maybe some of you know some solutions.
Much better than the Xperia z3v I had at first. The Xperia had a few odd things about it that bugged me, and the lack of root was getting to me. That is what made me switch.
But it did have much better battery life... I would have 50 to 60 percent battery when I returned home, the G3 will be below 20 percent most days.
The keyboard has a one handed mode, but its prediction and correction are not good. I somehow miss the space key and get run on words all the time, it's been a little frustrating. I know of no third party apps that have a one hand mode though.
The auto brightness is better than the Xperia but still not as good as it can be, it requires too much attention. It limits it's range and trays to be adjustable but it doesn't work well.
Its size has put it over my comfortable one handed use size. The one handed mode helps a bit though. Can't really do much about that. It seems to be the trend.
Its close to being a great phone but held back a bit. Maybe there are solutions to most of my woes.

Battery life for me is great. You might want to get Wakelock detector and see what is causing this. I can get 36 hours and still have 40% left. Also, it just depends on what you are doing with it. I send/receive text messages, make phone calls, surf the web, read news, etc. Usually, I have it charged before I go to bed and when I wake up 7 hours later, it's still at 100%. I leave it on all night as I use the phone as my alarm clock.
Now, I am rooted and I use Greenify to help hibernate a lot of apps. However, you don't have to be rooted to Greenify now. I don't hibernate any system apps and I don't sync a lot of unnecessary stuff either. I also have the Snapdragon Battery Guru app installed which works well. However, I will say, for a few days, I didn't root this phone, didn't use Greenify and used only the Snapdragon Battery Guru and I was still getting well over 24 hours of battery life.
I use Swiftkey and it has a one-handed/compact layout. It seems to be doing fine for me, but I don't use one-handed mode.
I feel you. Whenever I do any type of graphics intensive gaming (i.e. Real Racing 3) during the day, battery drain is crazy. When I don't use it as much, Ive had the phone go for two days. The phone seems to have great conservation when the screen is off, but that massive high-res screen has got to have something to do with battery drain. It's not the most convenient, but personally, I've found the best solution to be a quick mid-day charge. Phonearena did a charge comparison between phones, and the G3 is one of the fastest charging phones on the market right now. 2 hours for a full charge. Like I said, it's not the greatest thing to have to plug in your phone during the day, but I've found that even a solid half an hour charge makes a huge difference.

Well, yeah. Games are going to drain it no matter what and it depends on how long you play. I've noticed even with Game of War, an hour of gaming will drain it maybe 8% or more. Just depends on what you do with it.
Any phone is going to drain like crazy, but yes, the Quad HD display definitely drains the battery more due to the higher number of pixels. But, for those with every day normal use (not gaming), this phone definitely lasts more than a day.
Whenever I play a game, if I'm at home, I plug it in if I know I'm playing for a long period of time. otherwise, if I'm away from home, I know I can still play over an hour of a game and still have plenty of juice to last me the rest of the day.
I would rather have better battery than the added resolution screen. 1080p is very good for a phone.
I watch youtube and mess around online a bit on breaks. Same behavior as the z3v and dramatic difference in battery life.
I never found one handed mode in SwiftKey.
Nvm... Found it
The screen is the biggest user of battery... 60% according to the battery use chart.
These past few devices I have had... Has lead me to a conclusion.
All this undervolting and CPU throttling is pretty much useless.
The processor in this device and my last few, has had very little load on it for the most part. Some games may push the system, but general use and some youtube barely has the device going more than a couple steps above minimum clock speed.
Background services and sync... Small effects overall on battery.
It's all about that screen and it's power efficiency. Resolution has something to do with it as well. As the GPU must run harder on higher resolutions.
Turn down the brightness... And then I can't see the video I am watching.
An android phone with a current SoC, a 3000mah battery, a 4.7-5 inch screen, and 1080p resolution... Should be able to get well over 10 hours of screen on time, running video...
The radios are power hungry as well, but mostly in prolonged use like video streaming.
This size and resolution war has prevented us from gaining what we want most... Great battery life.
Still the phone ain't too bad.

The radios are power hungry as well, but mostly in prolonged use like video streaming.
This size and resolution war has prevented us from gaining what we want most... Great battery life.
Still the phone ain't too bad.

True with that. This isn't an 1080p resolution screen. It's more since it's a QuadHD, so that is definitely what kills it. But, I don't watch videos for 10 hours! LOL. But, I know what you're driving at.
Hi guys, this is something that keeps me up at night. The recent software update was supposed to make performance of the Moto Z better, and in actual daily usage I find nothing to complain about, but when it comes to benchmarks it's a whole different story, I have the uk version by the way. To be frank, I used to get about 129 000 in antutu, which is pretty low to start with, and now it's down to 126 000, geekbench is lower than you would expect from this phone too, at about 1350 single core and 3810 multicore. So basically I started this thread as a place where we could share our benchmark results and discuss them, because I have a feeling I just got an unlucky unit, because it also gets real hot real fast (up to 60 degrees celcium), and I can't make it last for more that 4 hours of screen on time, and I'm really not a heavy user. I just feel strange about this phone, because I love everything else about it, and it’s good that I do, because resale value on these things is beyond awful, tried to sell it for 500 bucks for months with no success.
Benchmarks mean abso-farking-lutly nothing. If they are keeping you up any night, you have a mental issue. I suggest you see a shrink.

Well, there is no reason to be so toxic my friend, my main concern is that I may be the only one here with such a low score, and since the score got even lower after some time that could mean I may have a defective device, and that would be a real problem to keep me up at night.
I don't think there's a problem with your unit, 4 hours screen on time sounds normal without the battery mod on. That drop in benchmark score isn't very significant unless it continues to drop dramatically. I have the UK model too, and it is underclocked by default to 1.8GHz. You could try the Turbo Z kernel to improve it
Also mine gets really hot fast when using Daydream VR or anything intensive but 60 °C isn't dangerous for the SD820. (You could check battery use in settings incase something is keeping your phone awake.)
Geekbench 4:
Single core 1369
Multi core 3779
Seems benchmarks are pretty similar. I'm on rooted Android N but stock kernel so same as yours.

The only benchmark that matters is the one between your ears. And according to you, it passed.
in actual daily usage I find nothing to complain about

Thank you for your comforting and friendly reply, in battery settings Android OS, Android system, and phone idle are on top when I'm not using the phone actively, I've had laughable results sometimes, like yesterday I had 30 percent battery left with only about an hour of screen on time, again no gaming involved, but this usually happens when I'm moving around, if I stay at home and nothing happens to the phone it usually won't drain battery like that. I think the reason the phone gets hot easily is obviously because of how thin it is, for example, when I keep it in the pocket it's just as hot as my body tempreture, since it just absorbs heat that easily, but has a hard time getting rid of it.

You're welcome. If you click on the graph you can see the awake time too, lately something has been keeping mine awake and draining the battery too. Not sure what it is yet, but if yours is getting really bad screen on time it could be similar. Likely an app running in the background keeping the phone awake which would heat it up more and drain the battery. There are wake lock detection apps that claim to be able to tell you which is causing this.
As you can see it's awake for long periods of time when the screen is off, and it really shouldn't be. Hope this helps :good:
I've not seen any discussion on battery life since the launch of the Note 10. Would people please share:
1. How is it now that there's been time for Samsung to fix early issues
2. Did Android 10 upgrade help?
3. Does it last through a day of heavy use?
4. Snapdragon or Exynos?
More info: I'm considering buying the Note 10 but the original reviews are mixed. Some say battery life is good but most say it's disappointing. It would be to replace an iPhone XS that is 12 months old, battery health is a shocking 84% and the SoT time is less than 3 hours, so I won't be buying any more overpriced junk from Apple. I'm in the UK so would be getting the Exynos unless I take a risk and grey import a Snapdragon, and live without the warranty.
More battery life is *always* better, but I really have no complaints about my Note 10 battery. It lasts all day, every day. I average 5.5 hours SOT, but it would get a lot more if I pushed it below 10% charge. However, I rarely let it drop below 30%, or fully charge to 100%. I try to take it off the charger between 60-80% to preserve long-term battery life. So while 5.5 hours SOT may seem low to other Note users, I am averaging 5.5 hours SOT from only a 50-70% charge, which is pretty damn good imo.
I disabled some apps that I'll never use, but otherwise I don't need to gimp it to make it through the day. I noticed a slight improvement in battery life with Android 10. I don't do much gaming, but I do a lot of web browsing, YouTube, and listen to Google Play Music and Sirius XM, and it has no problems lasting a full day.
I have the Snapdragon model. I don't have any experience with the Exynos model, but if you are in the UK, then I would recommend going with Exynos just for the warranty. There may be some YouTube videos comparing the battery and performance differences, you may want to look for those. I remember a couple of years ago the Exynos models were noticeably worse as far as battery, but I think the latest Exynos chips have closed the gap.
If battery life is a top priority, then you should consider the Note 10+ which has 23% larger battery (4300 vs 3500 mAh).
One last thing to consider: The Galaxy S20 models are right around the corner. I am not trying to talk you out of a Note, but if you can live without the Spen, you might want to wait for the Galaxy S20 Plus and Ultra. The Plus model is supposed to have a 4500 mAh battery, and the Ultra is rumored to have a massive 5000 mAh battery.
Edit: Btw, congrats on graduating from iOS. You'll love the customizability of Android, and now that RCS is available, you won't miss iMessage as much :good:

Battery time is average.
battery timing is inversely proportional to the time you are free

Thanks for taking the time to reply - appreciate it. Sounds like our usage patterns are similar. I don’t really game but I use web and media on public transport for a couple of hours a day, in poor signal areas so every phone I’ve had struggles.
Am trying to keep phone size down, the Note 10 Plus is definitely too big! I like the fact that with the standard Note 10 it’s almost the same size as my current iPhone XS, just 5mm taller.
Re graduating (haha) I’ve had android before. Before this iPhone I had the OnePlus 5T and really liked it until I changed cars and it completely refused to talk to the audio system.
I found a YouTube video comparing the Qualcomm and Exynos Note 10’s and in his test he got 7 hrs from the Exynos and 8hrs from the Snapdragon. Wow, bit of a difference.
Will see what the S20 (standard size) is like, and then decide whether to risk an imported Note 10 [emoji106]

Correction, the video of the Snapdragon getting another hour of screen time is the S10, not the Note 10, which means the Exynos is the 8nm 9820 rather than the 9825 in the Note.

So i got my Exynos note10 (not a new one, a used one but in a good shape) a week ago running android Q, and the battery drain was a little bit higher than average (compared to what people claiming in the battery section). So i decided to do a fresh reset by flashing a firmware using odin, after that i did some optimizations, disabling features that i dont really need, debloating some apps and waiting for the phone to learn my battery usage pattern (it took me around 4-5 days).So now I can get 7 to 8 hours of SOT using Chrome as my web browser, social media apps, and youtube. So yeah i think the 3500 mah battery is doing a pretty good job.
That’s really good, lots of owners don’t get that out of the Plus model

Can you tell us more what did you disable, what did you uninstall/disabled and more...

So the first thing i did was to flash a stock firmware and root it using magisk. Then i charged my phone until it get 100%, i use it until it dies and cannot get booted again (when the phone dies keep rebooting it until it cannot get rebooted again). I did the charging and discharging thing twice. I think this step is like calibrating your battery, correct me if I am wrong.
Then thanks to this post : https://forum.xda-developers.com/galaxy-note-10/how-to/galaxy-note-10-note-10-plus-debloat-t3964225 i debloated Bixby, samsung pass / pay , samsung sticker center... Do this step at your own risk because you can brick your phone if you didnt choose correctly what to debloat.
Then i enabled Adaptive power saving, put unused apps to sleep, Optimise Battery usage and i restricted background activity and i use dark mode all the time.
I disabled Air action and all features related to S pen ( i only use s pen for writing).
You may not notice a big difference in the battery life until your phone learns usage pettern ("Learning pattern" usage becomes "An estimated time" in device care battery's section)
If you are on a rooted phone then you can use greenify to hibernate other apps.
Additional information, my phone battery drains from like 100% to 80% much quicker and then it start to go slower and slower because each battery behaves in a different way.
Took another look at the Note 10 today and think it's an absolutely stunning looking device. Best looking phone around for me. I noted in the Samsung store that they don't offer any sort of satisfaction guarantee, which is disappointing. Would have been tempted to take one if I had some insurance on the battery life not working out.
But the S20 has now launched, and it's impressive from a specs point of view. Time to see how the S20 reviews play out.

Yes, the S20 phones are phenomenal, especially the S20 Ultra. Which means the Note 11/20 will be an absolute beast

You are wrong this is really old battery habits. For several years and actual battery tech it's not recommended to fully discharge , the best way to improve battery life is to stay over 20% and avoid fast charging. That is also not how phone calibrates batteries.

Battery life on the Snapdragon Note 10+ has been great. It stayed consistent with the Android 10 update. I had the Note 8 before this phone, and I'd have to say the 10+ is better.
Indeed the difference is not so abysmal as before

Actually, there is a comparison for Note 10+ Exynos vs Snapdragon and indeed, the difference in battery is now minimal, of course the weak point for the Exynos is still the Mali GPU. So it looks like for power comsuption is now more even between Exynos 9825 and Snapdragon 855 (which is kind of obvious since both are 7nm)

Interesting thanks.
One of the things I’ve been bitten with on iPhones is the effect on battery life of the inferior Intel modems they’ve been using for the last few years. I went from an iPhone SE to an Xs and the difference in signal strength was definitely noticeable, and that will affect power consumption too.
I’m not saying this is the same with the Exynos modem but do tend to think that at this point, Qualcomm modems are the better
