I have a Samsung Series 7 Slate and it doesn't have great battery life using common settings. I have been able to get relatively decent (for x86) battery life out of it by tweaking power settings. I set the max processor to 75% (it is a 1.5GHz Core i5 2nd gen) and the GPU to highest energy savings (integrated HD 3000).
Because Windows 8 runs on ARM and the majority of the apps I use ALSO run on ARM, I was wondering if I should fiddle with the max processor and GPU settings for even better battery life? I really haven't seen much of a comparison of the Core series with ARM (typically one sees Atom comparisons) and I am thinking that since ARM is not as powerful as x86, I don't need to run my CPU as high to get good performance in Windows 8 apps.
Should I be scaling my processor back even more and ramping GPU performance higher to match ARM specs or will it even matter much?
Hi, I'm new in this forum. I need help. I bought a Galaxy Note Pro 12.2 (SM-P900). I know it has two quadcores (one of 1.9 GHz and another of 1.3 GHz) but I think it only use one of them, because it lags a lot when I run games and another apps like chrome. Also when I run benchmarks, they only recognize the 1.9 GHz one. I tested Asphalt 8 and it runs at 20 fps or less. Also it lags when I pass pages in S Note. There's a way to speed up and take advantage of both CPUs? Thanks!
S Note always seems to lag (I don't use it, but others report it.) The app isn't optimized for 12.2". Try Lecture Notes.
Benchmarks see only one CPU because that's their limitation. They couldn't detect the second one even of it was running laps around the first.
Cores don't stack. So even if you have 4 1.9Ghz cores, it doesn't become 7.6Ghz. This is why the amount of Ghz matters so much for gaming and heavy apps. The Exynos is designed for multitasking, not heavy processing(games). That's what Snapdragon is for.
Next is the Mali GPU. It's weaker than the Adreno and doesn't handle 2K very well. Particularly in heavy games. Oh it does Candy Crush just fine , but it's like Intel HD vs Nvidia in terms of the more serious work.
If gaming was a priority, you should've gone for the P905 with the Snapdragon 800 & Adreno GPU.
You can try to get rid of most of the bloatware, that should at least speed it up a bit. Also replace the launcher with Nova or Apex, they use less system resources. (60MB RAM vs 800MB.) You can also try a factory reset, see if that helps.
Maybe someone else with a p900 can tell us if they, too, have the same framerate issue. (I've got the P905.)
The Note 3 N9005 and N900 editions have the same hardware as the P905 and P900 respectively. The N900 with the same Exynos/Mali has the same issues with lag in Gaming as the P900 does.
S Note can't be helped, that's Samsung's fault, bad coding.

Root it and pick one of the stock based roms because they are the only ones with kernel development. I'm on CM 11 because I love aosp but I'm living with the built in kernel. That's the best you're going to get as far as I can see, but there are a lot of really smart folks around here.
Thanks for replying. Your answers helped me
Asphalt 8 has graphics settings where you can change the level of detail. Change the settings to low (which still looks good) and play is completely smooth.
Regarding optimizing general performance, I'd stick with Samsung stock roms as the gpu driver is better than cm based roms. Change the kernel and overclock the cpu and gpu to 2GHz and 667MHz respectively. Use the synapse app to undervolt the cpu and gpu at the highest frequency steps, necessary to avoid thermal limits which drops the clock speeds. With these settings I get 41000 on Antutu and 996/3000+ on Geekbench 3. Very smooth performance for my tablet.
hi guys new to the forum hope you can help..im about to buy the wifi version but because of the lag im tempted with the lte now..my question is a do a lot of art work .sketching etc and recently artrage was released for android..would you say the snapdragon would be better than the exynos version for brush lag etc .I cant seem to get a good answer to this question ..the note 12.2 is a great size and much lighter than a laptop and reat battery life..
sorry wrong forum
Hi, i am new owner of Nexus 4 and there is one thing which is bothering me. Games are really running not as smooth as i expected from this hardware. I preformed clean install of a lot ROMs (Stock,PA,Rastapop,slimLP) and kernels (unleashed,franco,AK), i have tried overclocking CPU and GPU, changing governors to performance, flashing Adreno drivers from http://bit.ly/makostuff. Now i am running SimpleAOSP + AK Kernel .600 and what i found out is, that the gaming performance has not barely changed from stock, even if i overclocked to 1.9 GHz CPU and 487 GPU. Asphalt 8, Real Racing 3 and mainly GTA San Andreas are pretty laggy. GTA San Andreas is running better on friends old Galaxy S2 and LG L9 II.
Does anyone have any tips for gaming performance, some special rom-kernel combo, or some tweaks ? Or is this hardware really not that good for gaming ? Thanks for tips guys.
Greetings.
I'm thinking of buying a new phone and it's either LG G2 or I9506 (It's S4 with 4G and snapdragon 800).
And from various benchmarks, futuremark's slingshot as an example, it beats even S5 and any 800 snapdragon device.
Is it really that fast in real life performance? I know that Samsung is cheating on bechmarks by overclocking CPU/GPU while benchmark is running.
So how does the I9506 perform in real life? How does it handle games?
I watched videos of LG G2 running games with FPS meter on and Asphalt 8 dropped below 30 constantly at max settings.
This is the video: https://youtu.be/2IOvC5NUng4?t=4m38s
It's been 1 year since the video so the game might have been optimized for quad cores since Gameloft is known to port games to android from iOS, so that means they don't use more than 2 cores. This was also present with GTA games.
Could anyone install an FPS meter and do an Asphalt 8 benchmark on their phone and compare if it runs better?
I'd be really grateful since this is going to be a huge purchase for me.

Somebody posted a similar question and posted benchmark examples that were done on android 4.2.
I played Asphalt 8 on my S4 GT-I9505. Seemed to run pretty smooth. And that was when underclocked to 1.2 GHz.
Samsung cheated on the GT-I9500 version. Benchmark apps used all cores instead of just 4. An app can;'t overclock without root permissions.
all buddies here at xda i would like to know what is the difference between 64bit os and 32 bit os. and pros and cons of each os.
as i am seeing some development of 64 bit os for redmi 2/prime
please kindly reply those who knows.
note that i googled but didn't got satisfactory answer.
For 2GB (Prime) variant it's good. For 1GB, it's a hell.
Explain:
The 64-bit OS is based on ARMv8 Aarch64, with many improvements in instruction set, specially the SIMD instructions and about memory access. But it consumes more RAM. I flashed the MIUI8 arm64 in my Redmi 2 1GB. The whole system is blazing fast, stronger in benchmarks, snappy as ever. But after installing some apps, the device becomes slow because low RAM.
Maybe with a lightweight AOSP rom could take away the RAM usage issue and receive the full benefits of the newer arch. While it doesnt occurs, I'm very satisfied with my RR 5.8.2. Stable, snappy and fully customized.

You are wrong, also there is no performance improvements from 32 to 64bits (maybe better ram management and new cpu instruction set avaliable), I also seem to have the Redmi 2 with 1gb of ram, from all the 3 64 bits rom I noticed no performance decrease, maybe a improvement on the nougat arm64, I'm getting over 31000 on antutu, 560 and 1600 on geekbench, but arm64 is really nice to redmi 2, since it will unlock the support for some apps and games, also a prolonged support to when the normal 32bit arm art no longer be supported (just a theory of course).

I saw performance improvements between MIUI8 32 x MIUI8 64. Look: there is really many changes in floating point instructions (arm64 supports double-precision fp, for example) and memory access. The gap is around 10~20%. I saw it in another phone, Doogee X5 MAX Pro. After Aug/16 the stock ROM was converted to x32. And performance decreased slightly. Antutu score decreased arount 15%. So, arm64 have performance improvements over arm32.

Are you using another device? from what I know this is redmi 2, we have a different source from other devices, and don't trust benchmarks, they are always wrong, a 64bit OS for redmi 2 is a good deal, there aren't fps improvements, but overall ram management, smoothness, and a really high decrease in stutters is very visible.

What ROM are you speaking? I flashed in the past and the RAM management was terrible. The phone froze for 10 seconds to become "live" again. There is a AOSP/LOS based ROM build in ARM64 to make real-world tests, or have we only MIUI one?
About another device: was the only time I could see side-by-side the ARMv8 and ARMv7 performance in the same setup. And ARMv8 aarch64 was faster, snappier. Not only in benchmarks, but in real-world scenario
