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.

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.
OK here is the official SGS2 I777 Battery saving thread. I don't mean to be a culprit and post "another battery saving thread", but I am. So get over it. This thread is meant to maintain the battery savings threads, all in one place. INCLUDING: Battery savings tips, philosophies, and other methods of efficiently managing the charge that your battery witholds. Since I searched through basically all of the 17 pages in both the I777 and regular SG2 to collect all this. NOTE: THIS THREAD IS NOT MEANT TO ADDRESS BATTERY DRAIN PROBLEMS OR ANYTHING OF THE LIKE. DO NOT POST YOUR PROBLEMS HERE. This is simply a collection of what I found to be the most essential threads and information regarding efficient use of battery charge and battery savings. I'll update this every few months, or as I see fit. I don't see things changing much since the way a battery works, and our android os will be relatively similar over the years.
I realize that people looking for this information could just go through all the threads like any other xda troll would be the first to point out, but I also recognize the noob community for this phone (I was once there myself) and would like to be helpful in providing it all in one place to prevent others from wasting their time, whether deserving or not

THE TWO THINGS THAT KILL YOUR BATTERY THE MOST:
Super AMOLED Screen: Now it's all apparent to us at this point that android screens (S-amoled's) kill very large amounts of battery. You will save copious amounts of battery if you do not use your screen as much, hence why half of the people posting their battery stats have screen on like once an hour for half a second. They basically don't use their phones.
Data/Radio: Ever notice that when you put your phone on airplane mode before you go to bed, when you wake up it's only gone down by about 1%? That's because you're not getting any service, and have no data coming in. Believe it or not, the phones hardware is pretty efficient. CPU's don't use very much idle power at all, and I expect that to stay the same, even with quad-core processors coming out. It's mostly the over air things (and screen ) that kill our battery. Data itself uses a **** ton of battery. On a daily basis (And I've tried just about all the roms; CM7,CM9, MIUI (GB and ICS), SammyTW ones, etc.) I use a considerable amount of data. I try to have my data on most of the day since I get facebook notifiations and send/receive MMS's, but on the days where I have it off for a couple hours I start to notice, damn, my battery is still pretty high
EDIT: Using Edge/2G saves a lot of battery if you're someone who needs data on most of the day. I recently switched to instead of intermitedly turning data on and off, just having Edge on all day (for notifications) and then switching to 3G when I needed to browse or use maps, etc. Idle usage of Edge vs. 3G is probably around 40% less battery consumption (my opinion), it works really well for me.
PHILOSOPHIES:
If you want to compare your own battery life with others to get a better idea about things, check out this thread:

Juice Defender + others: I am a fan of this application. I used to use it for the first couple months I had the phone and it made a significant difference (mostly because of data deactivation). It makes 20-35% difference in savings from having not micro-managed anything yourself to then using the app. There are other variations of JD, GreenPower, Battery Booster, etc.

Fast Dormancy effects the trafficway in which your data makes it to your phone, both effecting the speed at which is arrives, and the battery it consumes while doing so. Check out this thread:

Underclocking and Overclocking: These are ways of tweaking your CPU usage. Underclocking is known for when you limit the maximum frequency, your CPU can clock to. So in laymans terms, what that transaltes to is your 1.2 GHz (1200 MHz) processor, can be changed to a 0.8 GHz (800 MHz) processor, if you were to underclock it to 800 Mhz. This is helpful to some almost completely dependant on your usage.
More elaborate, drawn out explanation: While your phone is idling, or sitting with the screen off, it is sitting at 200 MHz (lowest default - if you go lower than that your phone can become unstable [screen not turn on, etc.]), so underclocking won't help you improve battery usage much if you just keep your phone off most of the day. Undervolting would help more with that. if you however, find that you play lots of games, or mindless swipe across homescreens all day confused, or perhaps photo editing apps, or other things that use the maximum cpu frequency; then you will find that having your phone underclocked to 800 MHz, forces your cpu to work less during those heavy maintence situations, but in turn, prevents heavy battery drain. What this translates to in daily use: If you play angry birds, your phone's cpu might be jumping up to 1200 MHz (depends on your kernel settings - usually it's set to ondemand, in which case it will do so) during those swipes when the bird flys across the screen. However, that is not a very cpu intensive action, so if you were underclocked to 800 MHz, you probably wouldn't see any difference (lag, stutters) in your game play. However, if you were playing a 3D defense game, or esentially any other 3D game which requires you to scroll around the map, or has many many things on the screen at once (beyond fruit ninja and angry birds), then you would notice a difference in performance due to underclocking. I mention all of this because underclocking will be most effective during those situations, but it can also be the most hindering, in those same situations. All depends on how you're using your phone and what you're trying to achieve, while maintaining a certain level of quality.
Overclocking works the opposite, if you are trying to reach a certain level of performance (you just downloaded a new 3D MMO dungeon defense game and your phone is jittering and laggy during gameplay), beyond your default 200-1200 MHz clocked cpu, you may overclock up to 1600 MHz (some devs don't like you doing it - because it is essentially quite harmful for your cpu if used for a longer period of time), also depending on the kernel (again, devs created them) you may not be able to overclock, but on the majority you can.
To Underclock you will need an app called SetCpu (or equivalent) in order to change your over-underclock rate, as well as the scaling of your kernel (ondemand, performance [max frequency, all the time], conservative, etc.), also some roms have clocking options built in (such as AOKP).

AMOLEDs are supposed to be more energy efficient than LCDs I thought. That being said, I think one problem might be that many users of the former tend to keep their screens very bright because they are such a beauty to look at. I get what I think is good battery life by adjusting the brightness of my screen down when on battery only and by fine-tuning auto brightness settings.
One of the nice things about the S-AMOLED screen is that when it shows blacks, it's not using pixels. Pixels are actually turned off for the blacks. You can get further battery saving by using darker themes and inverted apps. Of course, that's not to everyone's liking. Me, I tend to like darker, tending towards minimalist screens as opposed to bright, busy ones, so it's a win for me.

First, in reading my paragraph I was speaking of JD's helpfulness in relation to not micro-managing (turning off data, etc.) anything yourself. In this case JD helps a lot....
Second, I didn't bash any part of our AMOLED screens, but they use a lot of battery...idk anything about how they compare to other screens, and idc...that has nothing to do with my post. We all have I777's, and that's the way it is, so I'm not too concerned of other screens.
I will say, that in light of reading most of your comments (which are found everywhere) , evidently, that you do at least make a good point, most of the time.

Yes data drains battery. If you are rooted (I hope you are since you are reading this on xda), you should get Droidwall. It's a firewall for your phone which limits certain apps to use network data, wifi data, or neither. Useful if you are also a little bit paranoid :silly:.
Another amazing app I also use is called llama. It is similar to tasker but it's free. This app allows me to set profiles and actions based on location (antenna mast instead of GPS to save battery) and other triggers. Not sure how ICS manages BT and Wifi scanning but those things use to drain my battery under GB so I got into a habit of toggling them on/off. Llama can do it automatically for me because I am lazy or sometimes I forget to.
I think any phone screen can be a big battery drainer if left on long and are set really bright. I have a habit of hitting the power button after I am done using it as opposed to just letting it shut off by itself.

They are more efficient than LCD's, and I made no notion to say they weren't. I simply said that they were one of the two main culprits of battery drain. I'm not saying our phones suck cus they have AMOLED screens, it's actually awesome. I'm just saying, like any other phone, having the screen on lot is going to kill your battery.
Yeah on stock (rooted after a month) I used to use auto-brightness most of the time, and sammy's auto seems a little brighter than necessary by default (so I'd keep it on 40% some days). But after switching around to different rooms (before I started tweaking auto-brightness) having brightness at what I'd actually consider an adequate level, versus a little bit brighter makes a huge difference. When the screen looks just a little too dull in all situations it really takes away from the experience hah
Also, I know black pixels are technically off on AMOLEDS, but I've noticed on many occasion when using in a room with no light on at night (pitch black, essentially) that when rebooting and hitting the yellow triangle screen (mostly black) you can see the black area of the screen. It's not completely black. It's definitely a very real looking black, but it still looks like there's a backlight behind the screen. Is that the case? Can anyone confirm?

While it may not have anything to do with your post, per se, I think it's a good idea for people to be educated about our screens since many *are* coming from the LCD world and some of the rules they're used to don't apply. And some of those rules very definitely have an effect on battery life, like the rendering of blacks that I mentioned above.

That is the case with LED screens. In a mostly black scene, the individual pixels for the black area are not lit, however there is still a backlight lighting the screen itself which you may see bleed through. This is of course assuming the phone LED works at least somewhat similarly to a TV.

So I guess if the signal is bad it tries to sync amd keeps doing it for a long time whih really drains the battery. Disabling background data helps even more but I like to get my emails so I do not.
Sammy based roms are the best wih auto brightness quickness. Aosp roms are always slow to react. I hate when I step outside and the screen takes for ever to adjust. But the sammy based roms also have high default brightness as you mentioned.

Ohh alright that makes a lot of sense then. Thanks a lot, that was really helpful for me! Yeah cus in the completely black screen sometimes I can see the little splotches that look like it's where the backlight is squished against the screen or something. I noticed the marks are in a different spot on my current I777 than they were on my old one (replaced cus power button stopped working). Yeah it would make sense that AMOLED's came around the same time LED's started getting more popular in TVs too (few years ago), pretty baller technology for a phone! I'm loving it haha

I disagree with you that Juice defender does not improve battery life. I am aware that obviously running an app in the background (Juice defender in this case) uses battery. But if the app is disabling your data (data uses battery..more than the juice defender app uses) then it's not possible for it to not increase battery.....just logic there. Anyway I'm sure there's been reports that say it does and does not increase battery, it's been obvious to me that it does, and it's logical to assume it does (if you know what I'm addressing) too. So I'll say to each their own. I do not wish to argue about things anymore, I will not edit my thread to your liking, you may simply dismiss that tip if you'd like.
I do not care about a report, I'm sure most people see the way I act and understand my reasoning. I probably overreacted a bit to your initial response , I've edited my accords. :cyclops:

Now...getting back to the topic....good point about tasks rom....I did try it out but frankly speaking it is still not at par with sammy base roms wih regards to auto brightness. It does rock otherwise.
I am currently on ktoonsezs MIUI port (love that guy. No homo)....and m pretty happy with the auto brightness

If the only thing which is holding you from using aokp is the auto brightness, there is a flashable zip in the fluxxi thread which gives great settings.

That is the case with LED screens. In a mostly black scene, the individual pixels for the black area are not lit, however there is still a backlight lighting the screen itself which you may see bleed through. This is of course assuming the phone LED works at least somewhat similarly to a TV.

OLED screens do not have a backlight. That is one of the things that make them much more power efficient than LCD. The pixels themselves in an OLED display generate light.
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.

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.
So I just picked up a Galaxy tab S7 plus 128GB with 5g.
Before purchasing I watched and read benchmark reviews but I'm getting considerably less performance than pretty much all benchmarks I have seen.
Single core/gpu/memory benchmarks are exactly where they should be but multicore is around 20% less than expected.
This is a new device, I even did a factory reset and tried again, not much installed and settings are default.
Anyone have any ideas?
I don't think you should believe in benchmarks anymore, it's better to refer to real-world tests and reviews from users.
Actually many Android devices have implemented hidden switches which temporarily disables thermal/performance constraints when it detects a benchmarking app being run (similar to a defeat device) so it scores much higher than it normally should, with a risk that the device might be damaged due to overheat and such.
From my experience, Samsung isn't doing well with the optimizations, making some games lag horribly, and this is getting even worse with the most recent Android 11 update.
I was just a little disappointed that's all, multicore is only slightly higher than my snapdragon 855 phone, nubia red magic 3. Much better single core, gaming and emulation though on the tablet.
It is running great though and I'm enjoying it.
Love the device ..... But it seems to handle Kodi worse than my Nvidia Shield. That's my pretty anecdotal comparison for Android devices
So after a bit of playing around I think I found the main culprit, it was nova launcher prime.
After using the tablet for a day I looked at the battery stats and noticed that it was constantly running and used over 20% of the battery over time.
Uninstalled and benchmarks are much better but not completely there, in geek bench 5 I get 980 single and 2950 multi, was 2600 multi.
I expect 3000-3200 from this device so only a little under now, it is possible that the benchmarks I saw were using android 10 before the update to 11.
Looking at the battery stats One UI is under 2% battery consumption by comparison.

Wow .... Would have never guessed. I do in fact always use Nova. Maybe I should delete. Wish I could save (backup) desktops like with Nova

I was surprised too as I have been using it for years now.
Not saying 100% that it will solve your your issue but it is at least worth considering.
It could be a problem my end or even perhaps how android 11 records battery usage but Samsung UI has 1.8% battery usage vs 20% for nova launcher, I need to use the tablet longer to see if that translates to longer screen on time.

So, a couple of days later I would say that I do seem to be getting more out of the battery, around one hour more with the same mixed usage, YouTube, gaming, reddit is fun app, Firefox, screen brightness 65%, volume full, 120Hz with WiFi and mobile data enabled.
Screen on time from 100% to 10% is roughly 7 hours, not as good as I was hoping for but I am hammering it and I expect that the battery test videos I have seen are using auto brightness.
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?
forum.xda-developers.com
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.
