Very good indeed save allot of battery life without any noticeable loss in performance and no reduction in screen's refresh rate
Many people praise this light mode but I don't really get it, if it's so much better and literally same performance as the standard mode; what would be the reason or higher performance of the standard mode? Doesn't make sense at all.

It's not the same performance. The peak clock of the X3 core is reduced in this mode. The thing is, it's not going to be noticeable in the day to day because the SoC is so beastly anyway. If you're doing heavier duty tasks like gaming or video encoding, you're more likely to notice.
ETA: I just found out that Light performance mode is disabled when Samsung's gaming tool detects a game so there would actually be no negative effect on gaming when using Light mode. Really there probably isn't going to be much of an impact other than on benchmarks that's noticeable to anyone as performance stability should be improved as well providing a smoother overall experience.

Actually, after 8.8.3.33 (not just ICS), I've noticed battery life to be excellent on standby, but less in actual use. I seem to run between 10%-15%/hour use when doing normal things (browsing, RSS reading, etc.).
I've been using some apps to look for the culprit, and all I've found so far is that the Prime seems to spend more time at 1200MHz and less time at lower speeds. I seem to remember more of a distribution of speeds prior to .33. I wonder if they didn't make the Tegra 3's mode changing less aggressive or something in the later builds.

another thing to take care of in custom rom I think, Devs
I think that ASUS and Nvidia will be making these adjustments for awhile. This is very new tech, and as they tweak one thing, another thing gets worse. I'm pretty confident that after a few more revisions they'll find a good balance between performance and battery life.
I remember some people complaining that there was a noticeable hitch as the Tegra 3 switch power states, and so maybe an adjustment was made to reduce the number of switches. Probably they just need to give some more weight to lower-power states.
I also notice that in ICS (didn't test it in .33), Power saver mode doesn't seem to have much of an impact. I need to run some longer tests, but certainly I can't notice any performance difference. So, that lends credence to the theory (at least to me, with the limited info I have) that the power settings are a little funky at the moment.
I haven't tested them thoroughly because I usually have my prime where I cannot charge it, but now that I have a dock I was wondering is there really a difference between "Normal" and "Performance" mode? If so how will this affect my battery life when docked in the keyboard? Will I still get an entire day (5-9 hours) of power using out of it? (Pandora, Youtube, Netflix, Forum browsing, and Web-based Homework)Thanks for any input. Also is there anything I can do to boost the performance as well? I am rooted.

yes there is a difference. its default mode is set to balanced mode @ 1.2Ghz. this is the best of battery and performance. if you want your battery to last extra long, put it on battery savings mode @ 1Ghz. you want ultimate performance, put it on Performance mode @ 1.3Ghz 4 cores or 1.4Ghz on a single core. the different modes does affect battery life alot and performance. but you can have prime on battery savings mode and still stream movies and such with no issues. The biggest key to battery life is brightness. that will determine how long or how fast the battery drains.
if you unsure just leave it on default balanced mode. there will be no task that it can't handle and still give you good battery life. even performance mode gives good battery life but drains at a faster rate since you getting maximum performance out of the prime in that mode.
More Kick
And too add a little more kick to your device here is a simple Overclocking app that works very well. I've used it since I've had my TP (a month or so) and it has never caused issue one.

I gather the OP wants to know more about the battery impact than anything:
Checkout this comparison: http://www.anandtech.com/show/5175/asus-transformer-prime-followup/3
That was during Honeycomb but the modes are the same, they just have a different name. Normal == Performance
As you can see there is very little difference in the battery life between balanced and performance.

Actualy since the latest update, wifi causes about half or more of all battery drain.
I own a nexus 10, I like it, but a big complaint by many is the battery life. Apparently a large portion of the battery drain is attributed to the screen, which makes sense due to its high resolution.
I was curious as to whether you can dumb down the screen but still have text legible and images viewable without too much loss of quality. Also if it would actually benefit battery life.
What I mean by that is turning the 2560x1600 into 1280 x 800 by turning off pixels in a checker format, every other pixel being turned off. If it looked terrible they'd be no point, if it didn't save any battery life they'd be no point.
Reason as to why you'd want to do this, is that if you were reading a simple text file you might not care about high detail, maybe some games don't work at high resolutions and maybe reasons I haven't thought of.
Is it possible? Would it save battery life? Would you still be able to read text?

Search around the forum a bit - I recall seeing a few mods that essentially turned the screen into a 1280x800 rendered screen. Until we see some stability improvements (hopefully) in 4.3, there are a few people still running it for the speed.

Thanks for pointing this out, I assume it uses 4 pixels as one, which is great for certain games and general performance I imagine. However I doubt it would improve battery life, right?

It could. Less demand on your CPU, GPU, and RAM should mean better battery life.

I don't think it would improve battery life very much, no.. I get awesome battery life when watching a movie or reading books, but when it comes to any kind of streaming (netflix in particular) my battery just drains, even more so then on my phone. I usually underclock when doing that, because it really doesn't require that much CPU. The tablet still kicks my laptop's butt in battery life, so even at 6+ hours I can't complain - and when I hit 8 or so I'm really quite pleased.

While it probably would reduce some drain, I'd imagine it would be minimal based on percentage of battery drain mostly being the screen. Perhaps under clocking and under volting would reduce some battery drain, the main way to conserve battery is reducing screen draw. That is why reducing brightness has such a big effect, I was hoping that you could turn off pixels to reduce the drain. Though I'm not sure it's possible or it would look good.
Lolwut? Battery life a major complaint? WAT? It is a 10in tab with insane hardware pushing an insane resolution that averages 7-8hrs of SOT. How is that bad? Some people's expectations need to be brought back down to Earth.

The majority of the battery life is not from the pixels....but the screen itself (i.e., the lighting).
Yes, the pixels does use up more CPU/GPU cycles, but the majority will always, and I repeat always, be the screen. Why do you think the iPhone gets such awesome battery life? They have a tiny screen.

Still, the rendering of the bigger number of pixels uses more power. Not sure about percentages though. This is specially important when running 3D games or other graphics-intensive apps. But I still credit your point about the back-light being a great deal of it.

If that's the case, the iPhone 4 and iPhone 4S should have gotten worse battery life than their Android counterparts back in the day. Did that happen? No. The energy footprint on ARM devices are so minute that the backlighting still takes the trophy in terms of energy footprint.

Apple only has a small set of fairly similar devices to support. All have the same series of GPU, similar hardware, and iOS is a less resource intensive OS. There are too many differing factors to fairly compare battery on two devices on the two OS's.
So ive noticed a marginal increase of battery life on my shield tablet by switching the power mode to 30 FPS and I was wondering if there was a way to change the G3's display refresh also? I just like experimienting with stupid settings like that. I dont use my G3 for games, mainly GPS and youtube, so refresh isnt that big of a deal to me. I would just like to find more ways to squeeze battery life and performance, as if my ZeroLemon isnt enough...haha.
Any help/Ideas would be AWESOME! Btw, running Eclipse!
Has anyone tried comparing the performance of S23U when using standard and light performance profile? Noticed any performance drop when using Light mode?
I haven't noticed a different in performance but I also haven't noticed a difference in battery life either. I haven't been able to see much of a benefit but since I don't see any performance drops I just leave lite mode on. Hopefully someone on YouTube does a battery comparison.

I have experienced the same thing. Don't notice any performance differences and didn't really notice any battery life differences either. I keep it on in the event it is making a difference cause I haven't noticed any negatives.
Light profile under battery profiles
Hello all, has anyone used this profile? If so, is it any good?

Standard vs Light performance profile
I haven't seen anyone do a comparison between the two, but what are your experiences so far with this setting?
forum.xda-developers.com
No difference regarding performance. However somehow I've got less SOT on light mode compared to standard lol
It is kinda strange when ppl claim on reddit that light performance gives them 3h more to sot. I don't see any difference on mine device. And I belive it is placebo what ppl writing. Also same to Ram plus. I try off and on and no single minute adding to sot.
I don't notice performance difference, but my battery seems to last more than before. Which was also goo... With s23 Ultra I no longer have battery Anxiety.
Maybe this function is just to turn off the "for galaxy" over clocking of snap 8 gen 2

I believe you are right. Because I have one of those device info apps installed and when I have light mode on it says the max GPU is 615 and with standard mode is 719 megahertz. So I think you are correct it just defaults it to the standard Snapdragon 8 Gen 2 setings.

Nah, it pulls back further on the core. You can see that in the benchmarks. It limits the maximum X3 core clock to about 70%.
Samsung Galaxy S23 Ultra: Benchmarks reveals performance difference between Standard and Light modes
Samsung's new flagship phones, the Galaxy S23 series, debuted with new performance modes: Standard and Light. That feature appears to have been a masterstroke, with benchmark numbers indicating a slight drop in performance when in Light, accompanied by significant prime core efficiency gains.

I did the test and posted the results in the battery thread. I gained 1 hour. First test with Standard was 10:51 and Second test with Light was 11:54.

That's a significant extra on the battery life. I'll stick with light since mostly what I do doesn't require heavy usage.

I am doing another test now with No Social Media Apps installed on phone. Just my normal phone, text and email apps, work apps and Netflix, Prime, HBO Max, Paramount+ and Disney+ for streaming apps. Bet I gain at least an hour without Facebook and Facebook Messenger installed.
Probably affect heavy performance core, so that with standard daily usage you can't see the difference
Haven't had any performance issues on Light mode. And quite significant improvement on the battery consumption. So I'll stick with Light.
What i wonder is the NPU (Neural Processing Unit) aka A.I.
If light mode lowers clockspeed from CPU and GPU, does it affect NPU?
I mean will it affect post processing during picture shots?
I've tried to spot a difference between these two perfomance profiles after may update and I did notice few things:
Light mode: device is less warm while multitasking, charging and casually browsing. However I did notice that I lose some "frames" using navigation apps such as "waze" and on heavier multitasking(spotify, facebook, reddit and instagram for example). Battery is a little bit better than standard mode but not that noticable at least for me.
The only thing I noticed was the phone got tangibly warmer when using the camera and the subsequent photo processing in standard mode.
You all know S23 phones use overclocked Snapdragon Gen 2, right?
If you want a stock Gen 2, just use light profile.
You won't notice anything.

Wow, now that's a bold claim! Light mode = standard Gen 2 clock speed and Standard mode = overclocked speeds...This needs to be verified.
