Hi guys,
my first post here, but i spent a lot of time on this forum in the last days stealing information here and there so i would to thank you all for your incredible effort on get this phone better. Now i think it's time to share my thoughts about this smartphone, and ask for some doubts i have.
- Display: the size is awesome, but honestly i found it too much saturated, is there any way to change color saturation? Plus the reading is not that good... the characters, expecially without zoom, look too fuzzy. I have to admit that, imho, readability was better on my old iphone 3g. Someone feels like that? For multimedia, however, this screen is awesome.
- Lags: I can unfortunately notice some random lags while opening application or switching from market to installed apps, even with the oneclick lag fix (512 MB) installed (quadrant reports 2200+ score, if i remember correctly). I was tempted to try the hackheclair cooked rom, any advice about this?
- Battery: another pain. It seems that the phone drains the battery too fast in standby mode. In 6 hours (last night) it drained more than 20% of battery life. This sounds strange to me since many users reported an 1-2% battery drain during night. Please note that i killed all the applications and widgets before leaving the phone in standby. The only one thing that i'm unable to kill is the touchwiz UI, since i use launcherpro as default launcher. Do you know any way to kill the touchwiz UI?
- Memory: here is my biggest doubt. Shouldn't this phone carry 512 MB of RAM? When i check the running services the application reports a total of 256 MB of RAM. Where is the problem?
here are my phone details:
Firmware version JM5
Baseband XXJM3
Oneclick Lagfix applied
Sorry for the huge amount of questions, i heavy used the search engine but i haven't found any solution yet.
thanks

1. There is an app in the dev section to reduce text size, go check it out
2. That's odd, no lag in my end and i've applied One Click lagfix 1.5 .apk, i'm using SamSet's 1.9f ROM though.
3. At the moment there is no way to get rid of the TouchWiz UI but devs are working on a clean ROM, a Cyanogen mod ROM which is basically stock Android. Not too sure about the Battery issue, someone else can shed some light on that, but i do get 1-2% drop at night...
4. Eclair 2.1 does not utilize all of the RAM, and Samsung hasn't chosen to either, so we're all waiting for the final release of Froyo in a few weeks and then hopefully that will utilize all of the RAM, or there will be a workaround.
I was going to ask about the fuzzy text myself. It doesn't always seem to be so but a lot of the time the white titles of apps or text in widgets etc. It looks like it is a little out of focus but all images and coloured text appear pin sharp so far. Very odd.
your coming from an iphone 3g and your complaining about battery life and lag? you taking the piss?
and as for the screen, its better than any screen ive ever seen, i lol'ed when my mate put his iphone4 on full brightness and watched the battery go down in minutes, so dont go there with battery life.
try reading the forums and you'll find out that your problems have got a slightly better with more recent firmwares
sorry still ranting, 'fuzzy letters' roflmao!

Actually the reason for limited memory is not Eclair. The amount of memory available is governed by the kernel and the kernel on the Galaxy S supports the full 512MB. However Samsung creates a large ramdisk on /tempfs (160MB) which explains why reported RAM is around 320MB.
As for the fuzzy fonts, this is the result of using PenTile matrix in the display. Just search for PenTile, there are many threads on these and other forums discussing that.

Is there a fix ?
Not without changing the entire screen.
After a while you get used to it, it's just jarring coming from a regular LCD screen.
Don't worry about the battery, it just needs to be broken in, be sure to charge it fully then use it till the phone shuts off then charge fully 3 or 4 times when you first get it. It took mine a week or 2 but now I get a couple days of fairly heavy use out of it compared to half a day when I first got it.
Another recommendation I will give is to try not to categorize this with another device. I came from a BlackBerry and as much as I hate to admit it, I had some BlackBerry withdrawal issues LOL
I'm now a happy camper and haven't experienced the lag too much. I did experience too much lag on JM5, downgraded to JM2 and lag is gone except for LauncherPro, so tried going back to TwLauncher, was happy, and now finding that ADw is a very good launcher in itself.
Bottom line for me is that I wish there were more apps with the same caliber as the App Store's, but it does what I need and more.

Can anyone in late Eclair version's confirm the tmpfs theory (one way to do it would be to change the settings I guess so that the tmpfs is bigger, 200mb, and see if the ram drops)

It would be better with a non serif font that was a little larger. Surely this is possible?
Look at the the thread http://forum.xda-developers.com/showthread.php?t=762116in the "Android Development" section for more details.

I'd bet money this is more than just a breaking in problem. The battery drain doesn't drop by 95% (20%->1%) after a few cycles. (more on this later).

First, let me ask, do you use a task killer other than the touchwiz task manager? Do you let it run at night? If so, stop, this will cause the 20% drain nearly by itself.
Next, look at the apps that you have installed? How many do you have installed? Maybe some are doing some heavy lifting at night when you are sleeping, this is almost definitely a sync and/or app related issue. Download Spare Parts to get more detailed information on your battery drain.
Here's the issue with the battery. First, the easiest way to fix the problem should be juicedefender and ultimatejuice, but it will cost like 1.99 or 2.99. Then set up sync and maybe 3G to go off at these hours.
Cheaper fix: turn sync off at night (I assume this is running, but actually, it might not be, you might just have random data going out). Also, potentially turn 3G data off at night, this actually prevents me from getting any data and that's what I've seen improve my battery life more than anything. ultimatejuice would make this automatic (I think).
I own both the iPhone 4 and SGS, and i agree that black and white text in the iPhone generally looks sharper and more crisp. I had been using the iPhone for about a week before finally being able to acquire the Galaxy S Vibrant off contract, and i really wasn't used to the display for the first day or two. I was surprised because so many people raved about the Super AMOLED screen, yet my eyes were so used to retina display, i was able to notice the pixels on the Galaxy S screen. After the first two days though i got used to it and it looks great to me now. Actually, i had gotten so used to the customizability, as well as the Menu and Back button, and the bigger screen size, the crisper graphics on the iPhone 4 is easily negated.
Anyways, if there is a way to make text look sharper on the SGS that would make it a perfect device for me.
my battery life last very good compared to other phones
i get around a day and half screen brightness full uses for about 5 hours
wifi turned on the entire time and very heavy use
when you first got the phone did you let it drain completely then charge it completely and repeat a few times or do you just plug it in when ever ?
i had the htc legend before and the battery sucked and as for the screen
im very pleased
my bad about the RAM question, must have got mixed up

I've directly compared this screen with the HTC Desire (both AMOLED and SLCD), the HTC HD2 and the iPhone 3G & 4.
For me, its definitely up there, but I kind of agree with you on the text, when zoomed out it's not that great. That said I disagree that the iPhone 3G is better on readability - the SGS definitely is better. It's only not that great when compared with an LCD of an equivalent resolution. The HD2, Desire SLCD and especially iPhone 4 (which is stunningly sharp for text). However, its better than the Desire AMOLED.
For general UI use, I'd put both Desires and the HD2 behind the SGS and iPhone.... on the whole between the SGS and iP4 I'd say it was a draw, with both looking very sharp, clear, and colourful - the SGS is more colourful, and larger, but the iP4 is simply sharper.
For viewing pictures and movies, the SGS is clearly the best, with the best constrast, subjective detail levels and plain looks the most impressive. EVERYONE has commented on how good it looks for this. On the iP4, this is its weakness - its small screen, almost-square aspect ratio and slightly duller colours make it far less impressive looking than any of the others.
I'd rank them as thus:-
=1 - SGS
=1 - iPhone 4
3 - HD2
4 - Desire SLCD
5 - Desire AMOLED

The lags are disappointing IMO. With JM2, and the internal SD fix (cant even remember the name as there are that many fixes now), it was clearly better than stock, however not all animations are smooth, and there is a definite lag at times, seemingly fairly randomly too.
However, I've largely fixed that... some people seem to doubt autokiller, however, I can say it works for me - I set to strict or aggressive for the best results. I don't know why it works, and I can't argue against those that say it makes things worse, on paper at least, but my experience is different, it DEFINITELY helps.
Also, oddly, turning the GUI animations off too has made a significant difference. I still have the Launcher Pro animations (app drawer and pinch home screen view), and the gallery is still animated, but other GUI animations are disabled, and its a lot snappier, and I dont really miss it.
Now the only lag I get is the browser lag as in the link below, but even then Nicolocopus suggests a later firmware may fix it.

Battery - the biggest drain IME is the 3G data connection. Make sure when you're in a place with wifi to leave wifi on over the 3G data connection. Make sure the phone isn't set to send the wifi to sleep (wifi sleep policy IIRC) as the data connection will kick in while the phone is asleep. Other than that, some drain through the course of a day is par for the course.
The other thing is the screen, turning down to minimum brightness is actually more than bright enough for indoor use, and seems to make a difference.
As for Launcherpro / Touchwiz, AFAIK once you set LauncherPro as default and then restart your phone, the home screen portion of Touchwiz (TWLauncher) is no longer running. You wont be able to get rid of TW completely unless a custom Vanilla ROM is made. Not all of it is THAT bad though, really.

Cant comment other than to say, I dont know about this, so many different "opinions" fly around - all I can say is Samsung advertised it as 512mb RAM, so I think they'd be pretty stupid to give you a phone with LESS RAM than advertised - but you never know, I guess.

Aside from all this... "killing all apps and widgets" does nothing to stop the biggest android battery killer, Google sync. Google sync is always running unless you disable it.
If you really want to see how long your phone lasts in stand by, install APNdroid and disable your data connection before you go to sleep. You will have miniscule battery use during the night if you do this.

On the old DJF4 firmware, with 3G and sync on, battery drops by 2% per hour on stand-by. With the new JG4 firmware, it is now 2% drop in 2.5 hours. This is much better compared to my iphone 3GS which loses 10-13% over 7 hours on standby with sync on.

Most software I had report 326Mb total instead of 256Mb. Which variant of sgs phone do you have? I have the galaxy s i9000.
yeah these batteries needs to be drained completely before charging again, else it doesn't hold proper charge
i always push it until the phone turns off (shutdowns completely) itself, then i change the battery pack
i cycle through 3 of them

well switched from Nexus 5,,,to be honest knk knk feature sold me...also camera and build design helped but i am pretty disappointed by the camera it lags like hell in low light...even my note 2 still shoots better picture in low light than g2...
model D802
anyway now my concern is heating...its always stays in 28-30 degree in normal use....i am using Gsam battery monitor...stock rom and kernel,,,
another thing i noticed when ever i browse for a while or plays video in utube like 5-10 mins the area of volume button in the back becomes warm,,,is it normal? not extreme level but i can feel the warm...dont know abt rest of the body as using back cover...
any friendly suggestion plz??
peace !!
the volume/power button area becoming warm is normal. playing videos or games and phone heating up is what most phones do. keep in mind these processors dont have fans blowing on them. is the 28-30 degrees in celsius? i know farenheit and normally i wouldnt want my phone to get past 100 degree's F. 30 degrees C is only 86 F.
I once saw a G2 lower it's brightness automatically due to overheating (and the fun thing is I didn't play any games or videos, just normal stuff).
I think the G2 has overheating problems.

Not all G2s have this problem. Ex. My first G2 was perfect. No overheating, looooong battery life, high benchmark scores, perfect phone. Got damaged when snow moisture got into the speaker grill and shorted out the top portion of my screen.
Got my replacement yesterday and noticed right away the screen had a yellow hue, the phone over heated like hell and had horrible battery life.
Nothing I tried would fix the issues. Back to the carrier it went. Hopefully the 3rd phone is as good as the first. Trust. ..if I gave you my first G2, you'd be singing praises in the long battery life thread. That phone wouldn't die no matter what I threw at it...the best part..it didn't overheat either...there are good G2's out there.
Hi, I have been using the phone for the past 2 days and realised that it heats up pretty quickly. It was particularly hot at the top part of the back of the phone, the area where the NFC logo is located. I did several "tests" to see how fast it heats up, and I made sure that the phone was cooled down before each try.
Firstly, I used the phone for browsing the internet for about 15mins and realised that the temperature(battery) has risen to 43 degrees celsius. Next, I tried using its camera and took several shots and after about 5 minutes of use, the temperature has also risen to 44.2 degrees and the a message was prompted stating something like "the temperature is too high! camera needs to turn off." I then tested the video recording in 4K resolution. The recording lasted for only about 3mins 40secs before the message was prompted, and the recording was not saved. The temperature rose to 44.5 degree celsius.
I understand that the automatic shut off of the camera was to prevent any hardware damage from the high temperature. However 15 mins of browsing and less than 5 minutes of 4k recording does not appear satisfactory from a user's point of view, especially after the device being touted as the best Sony has built. I hope that a software update can help mitigate this issue, as it will be a huge hindrance to the day to day usage if the issue remains. Does anyone else have the same issue?
Just own it only 1 day and I have no heat problem. A bit hotter when using under direct sunlight with 3G in about 1-2 hours. Totally no heat problem . Mine always under 40°.
Sent from Z2
Much cooler than my Z too. Even with constant LTE data use
Sent from my D6503 using XDA Premium 4 mobile app
Could it be due to some background processes like media server? First time I booted the phone, I took only 2 pictures when the phone complained it's too hot, and indeed it felt very hot to the touch. Subsequently I don't have this issue anymore.

I tried running the "tests" in safe mode with the same results, which eliminates the probability of 3rd party apps affecting it. I have also tested a few display sets in my local sony centres, same issue. did anyone actually tried 4k recording?...or using manual mode for the camera over a period of 5-10 mins?....

What's the ambient temperature when you run the tests? Where do you live? Could you record a video to demonstrate what you're seeing? It's strange you're the only one to have mentioned it so far.

Well i got to tell you that all snapdragon 800 SOC heat up doesent matter the phone producer,i have an lg g2 and it heats up relativley quick its not a defect its a must because its a 2.3 ghz clock not a 1.0 so every time u do demanding tasks the proc will heat up you cant do anyting about it,you can try to change it maybe you got a faulty one but keep in mind if you get a new one it will heat up non the less depending on task.
And another thing when battery temp shows 40`C the CPU temp will be like 70`C+<<
Check this out! 38 degrees Celsius! Is that normal for the Z2? The m8 is only in the 28-30 dergees Celsius range.
And here are some m8 different user sceen shots...as you can see the temperature is pretty stable, between 28-31 degrees celsius, a bit lower than the Z2's 38 degrees. I wonder why this difference in temperature between the two?

Do you know the ambient temperatues of where the two phones are being used? Taiwan and Singapore where the Z2 is released are hot countries. The M8 has been released world wide.
If the M8 is from the UK where the temperature is less than 20C and the Z2 is in Singapore where it is ~35C, its going to be much easier for the Z2 to heat up.
I'm sure the Aluminium shell of the M8 also helps with heat.

Or maybe its because of the waterproofing on the z2 wich is sealed up and has no open gaps through heat can emanate and cool down.

Yes it could be, but that is speculation, although I'm sure the M8 doesn't have air circulation inside either.
I think some of the difference could be down to environmental factors.
Ambient temperature is the key thing here. Battery temp means nothing without an ambient temp. My one X, which is my second, they both get around 50 degrees when under load. It's normal. 40 degrees is absolutely fine, it slightly warmer than body temperature. Lol
No one cares about Battery temperature!
Battery temperature won't go over 45°C Anyway!
Check out the SoC temperature! that can reach up to 75°C
Does Xposed work for Z2 ? There is a cool module called "CPU( or SoC) Temperature in Status bar" It does exactly that! Got that on my Xperia Z and it shows me always how hot the phone really is.
Oh boy not the same crap from Z1, the overheating problem & camera shutting itself off because of that, was the main reason I skipped on Z1, Now it's the same with Z2? bummer
anyway this is what I read today from sony:
"We are aware of some users encountering issues when shooting 4K video for extended periods. Shooting movies in high quality 4K resolution can make significant demands on your phone's processor and battery life, as well as phone memory. Therefore for the best experience, we recommend you install a high capacity SD card (Xperia Z2 can take a card up to 128GB) and shoot 4K video in short bursts of no longer than a few minutes at a time." -Sony Mobile Singapore
Wow didn't notice this. There is indeed a High Temperature Warning after recording 4K for about 3 minutes and the camera shuts off. Thankfully, 4K isn't that popular yet and there are no issues recording at 1080p.I hope Sony finds a solution soon because that 4K feature is really advertised.

Agreed. You would think their testers would have noticed that prior to launch.

Check this out! 40 degrees Celsius! Is that normal for the Z2?
I came across some strange CPU behavior on my Exynos Note 4, and I wanted to see if there's a pattern between the SD805 and Exynos versions.
First, I used this app A1 cpu tool to get a real-time measure of cpu clocks. I installed it on both my Note 2 and Note 4.
Now, when I hover my s-pen over the screen (enough for the cursor to show) OR touch the screen, the CPU jumps up to 1300mhz (max power). On my Note 2, it will only get up to 800mhz (half of it's max CPU speed), which leads me to believe that the Note 4 is being too aggressive with CPU scaling, and it's resulting in poor screen on times.
I'd like to hear from both SD805 and Exynos users to see if they exhibit the same behavior. There should be no reason why Sammy is cranking the CPU up full tilt just to keep the s-pen cursor on the screen - or to handle touch events without anything major happening on the screen itself.
Hmm.. good observation and findings chap.. lets see what samsung has to say er... or any devs
Interesting, but if you have poor SoT, this is not the cause.

It certainly could be if my device use involves a lot of screen touch events (i.e. not watching movies). I type a lot on my phone, and if the CPU is running a full power for each key press, it can certainly cause more drain than it needs to.
EDIT : I will add that bench marking for battery life WITHOUT touching the screen gives me very respectable times. SEE SCREENSHOT

There have been more people complaining about poor SoT - the probability that all of them are using the stylus in such an intensive way seems small.
I can testify that I also use the stylus taking notes during meetings, sometimes as long as 2 hours. I never noticed a SoT reduction because of this.
However, it may be useful for you to post your battery usage stats. We could get a better understanding of the root cause. BTW, are you rooted?

Interestingly, simply hovering the s-pen over the screen will ramp up the CPU too... I have a hard time believing that it wouldn't impact battery life.

Are you measuring the consumption, like in drain per hour or something like that? I notice drain between 12% - 20% per hour simply depending on very minor differences in usage (i.e web browsing vs. tweeting). I tend to use the stylus a lot.

I am rooted and get good standby time and expected battery life (i.e with gaming). But regular SOT sucks and I barely pull 4h most days.
I'm hoping that Snapdragon users can confirm whether their device ramps up the CPU on touches too, or if it's just Exynos models (that could explain why people are experiencing such a variation in SOT between the two chips).
I wonder what happens if you still type a lot, but without using the stylus. That would measure if it's the touch events themselves or the stylus hovering.
When I said before that I don't see a SoT reduction while using the stylus it was just a subjective impression. I didn't actually measure it simply because I didn't feel it's worth measuring.
If you're right about this, I really hope Samsung comes out with a solution.

Benchmarking with actual touch events would be very time consuming, but if I could disable CPU throttling for touch events, I could test with general use.
I read somewhere that this could be done, but I haven't seen any cpu control apps that do it on my stock Note 4 kernel. Perhaps it needs to be custom (or changed by Samsung)?

So, this is what I was talking about: http://forum.xda-developers.com/showthread.php?t=2532422
"input_boost_freq = Boost CPU speed to this frequency on touch screen events. Measured in MHz."
I would LOVE to be able to adjust that on the Note 4! I believe there's either a bug or an over-aggressive use of this function.
I jumped in and bought a K1 to replace my dying GPad GPE. After 3 days, this seems like a huge mistake.
The K1 is very laggy in basic apps like Play Store and Chrome, does not register touches very well and has terrible battery life. I even charged it overnight and didn't get a full charge. On top of that, I am constantly getting the screen overlay message any time I need to enable a permission.
What could be causing this? This tablet is so highly regarded I don't get it.

For charging you need a 2 or 2,5 A charger. Then it will charge (if it's not faulty) in around 2 hours. The screen overlay message is coming from the quick launcher (or how it is called). So disable it or give it the right to draw over other apps.
I don't have problems with lags or touches. Are you on the latest updates?

Its got a crappy Nvidia CPU in it, thats the issue. Like my N9, that too is crap, again, Nvidia inside.

I am using the correct rated charger. This even happened when charging with the tablet off.
I am on the latest update. I waited to install my apps until after all updates were applied. The touch issues may be lag related. The back button almost always requires multiple touches. Keyboards often time register multiple touches or just freezes.
I am also noticing network issues. Apps report loss of connection when the wifi shows connected.
I hate to say it, but I am leaning towards returning this for a Samsung.

Also a recent owner of the k1. Running stock firmware (1.5) but with BitO-K kernel. The only thing I am experiencing is mediocre battery life, charges from 50-100% in under an hour using a 2.5A charger. The only thing that sucks, and this goes for android tablets in general, is the removal from 4.4 of the TabletUI. Seeing we're already at 7.1 and TabletUI is still dead, it looks like we'll have to fight to get it back again.

That lag is not normal. And my tablet charges from around 10% to full in about 2 hours. Maybe you should try a factory reset. If that doesn't help I would return it.
I won't buy a Samsung tablet. I would try a replacement. I own the k1 for a year now and I'm still very satisfied with. And Nvidia updates it. Which Samsung usually doesn't.
Don't listen to Nvidia trolls... ⬆
Your experience does not sound typical. Perhaps it's a hardware issue, but I agree with @edisso10018 that the first step would be a factory reset.
Wish you luck!
The Nvidia CPU is pretty good shame it's not the X1, It performs better then some of my phones with QC chips, Do a factory reset and see if the lag is still there, Battery life is poor can agree on that
My k1 is over a year old it is still playing games with no trouble yes a agree with the battery life but mine charges with no problems a have noticed a little slow down but am not running bit os updated kernel yet but a still rate 10/10 best tablet a ever owned.
Tablet is laggy, no denying it.

K1 here-- I don't run stock (DU 6.0.1), but I used BitOK for a while and realized its not very good. Switched back to stock kernel (from my ROM) and its more stable. You don't lose out on much anyway-- BitOK doesn't have features I want like voltage control. Examples of instability caued by BitOK: GPU was stuck at ~350mhz, would not ramp down fully to 72mhz. Also stock is smoother. You can still use adiutor to monitor and control a few things.
One more thing: be very careful when flashing blobs and other stuff in fastboot that it is for the K1 version and not OG shield! A lot of devs posting these things arent explicit as to which version. DTBs and Blobs are specific to the shield type-- one might work for the wrong tablet version, or it might brick it, or it might be unstable.
As for the Batery life I can tell you it does suck even on the best case scenario. There is no way around this as it is small and the large screen, as nice as it is, sucks a lot of juice. Lowering brightness helps somewhat but still I'll be lucky to get a couple hours of SOT out of it.
For the price its a great tablet, with a few small compromises, such as bat life, but thats the price you pay for great screen and sound at a cheap price. We are lucky to have at least a few devs still doing work with this device, and luckier still that nvidia is STILL supporting it with updates, even if slowly. They recently announced 7.1.1 will be forthcoming.
Mine was laggy too, I flashed stock firmware with my PC and now it's working perfectly.
Bought mine as a refurb and it works fine. I think you either have bad hardware, or a bad install. Try flashing stock and see if it improves.
Tbh my only complaint is with battery life, I switched to BitO to see if it got any better, the tablet is smoother with this kernel than stock but the battery is the same, I wish we had UV'ing, my favorite setting on any kernel, back on my N10 my battery could easily be improved 10-15% and the heat was reduced drastically, good binned ones could shave up to 200mV on some steps. K wish this was implemented

I just bought a K1 (discount price 169€) and I don't have this problem at all. Even if I use only 1 core (settings performance) for basic app it's smooth smooth smooth.
And the battery life is huge !!
For gaming tho I switch back ofc the performance setting.
:good:
I bought a K1 three weeks ago to use as a display for my phantom 4 quadcopter. I am very impressed with its performance. I'm not experiencing any lag other than at startup. Once it's up and startup is finalized I dont have any problems. The battery life isn't great, I'll agree there but hopefully it gets better with Nougat.

I bought a K1 last week to replace my aging Nexus 7, did a factory reset and still wasn't satisfied with it being laggy. Did my share of Google searching and finally stumbled upon a quick fix to try : disable Daydream. Since changing this one setting it has been very smooth since, no issue for lag or touch registrations.
Give it a try, might not help your charging but I did notice a much reduced battery drain while sleeping also.
My only other changes were to root, change the DPI to 240 and use the Google Now Launcher which compliments the display nicely.
I wasn't happy with it as well until I flashed cyanogenmod 13 and a custom kernel with overclock. Now it's a beast, battery is great, signal as well. And I also now have the option to OC the processor to 2.5 GHz before I play some more demanding games and then set it back to 2.2 or even lower if I won't need all the juice. Seriously, the stock marshmallow ROM sucks, I have only heard bad stuff about it. Also, the nougat update is about to come out so I'd give android N a chance, too.
About the battery life -- see which apps are using the most juice under settings/battery/. Some of them may be using more CPU cores, and have a higher frame rate than is needed. Go to settings/App optimisation/ and crank the numbers down. Next go to settings/Accounts and see the long list of things that want to autosync with you. Turn the autosync off for those you aren't using. Turning off wifi except when I am using it has made a significant difference for me as well.

Putting the CPU at 80 or 90% CPU speed in the performance settings will get you that reduced power consumption. You might not even notice the speed difference. These speed tiers also run at lower voltage.
Using the GPU frame rate limiter will dramatically extend gaming time too. I find 30 fps acceptable most of the time.
Of course it would be nice to run the thing unrestricted, but it's just not practical when you also want battery life. Look at what Nintendo is doing with the clock speeds of the X1 in the Switch.
