I am considering using a custom ROM on the transformer, but is it worth it, I am mainly after performance increases. I see on a few that there are higher benchmark results, but does this actually translate into a real world speed increase?
I remember some custom ROMs for the original i9000 Galaxy S doubled the benchmark performance, but that was more down to "cheating" the benchmark than anything else, although it certainly was noticeable at times.
One of the slight criticisms I have of the TF101 is a slight amount of lag / lack of responsiveness occasionally - not a deal breaker, but if it can be improved then why not? Obviously not at the cost of stability though.
I think the SGS2 has spoiled me a bit here!
apparently there is a big increase (mostly from overclocking). i had the standard firmware for 3 days only, so I can't really tell, but one of my co-workers has a locked B70 and was wow-ed by my TF, the smoothness and speed of it.
Yes, I'm waiting too, to root it and put a cutom ROM on. I read, heard and saw the performance difference. Mainly from the overclock, but also thanks to kernel tweaks and stuff. So If you can root, do it

I've never been that keen on the idea of overclocking, as I prefer to have a bit of headroom, but I guess if it is safe and makes a big difference, then I would give it a shot. What would be a good middle ground for stability / speed ?
1.4 IMO is very stable and doesn't increase heat or use more battery but the real world performance is noticable. I have never run a benchmark so I can't give you any numbers. Just my normal use.
Cheers for the reply.
Is there any one ROM that stands out as being the best performing?
Contrary to what people think they all perform about the same. There is no source so everyone is building of the same stock rom. If you want the same look then go with Revolution. If you want a little tweaked then go with Prime (What I'm on). If you want the tweaks and a nice tools package then go with Revolver (What I was just running). All 3 devs are really responsive to problems
If you start from a clean base and don't restore any system data from other builds then they will all be fast. The real speed difference is in the kernel and those can be flashed seperately from the rom. Clemsyn is really putting out kernels this week. Some good. Some not so good. Go with whats right for you.
EDIT: I have actually installed all 3 roms in the last week and run them at stock and at 1.4 Ghz. They all performed exactly the same for me. They were all equally stable. I don't use benchmarks because they can be fudged.
I've used all three too. I notice huge improvements with webpage rendering. It's almost as fast as my laptop, where as before I avoided using the browser if possible. The ability to hide the status bar is a really nice addition to the latest version of revolver.
Edit: autorotate is also alot faster.

There is no such thing as an overclocking "middle ground" when dealing with mobile chipsets such as the Tegra. It's not like overclocking a desktop computer where the CPU will constantly run at the specified speed; mobile chipsets are pre-configured to utilize only as much power as necessary. For that reason I always ramp up my tablet to the max clock speed it can reliably handle, because then the governor will handle balancing between speed, stability, and battery life. My clock speed can range from 216Mhz to 1624Mhz, and on the interactive governor I can still achieve a good 8 hours of battery life from a single charge.
Of course that's not to say that you couldn't constantly run at 1624Mhz all the time, and I do sometimes lock it to that speed for games. But for much of the OS interaction, it's not necessary to run at full speed all the time, and you won't notice a difference even if it is locked at full speed. It just comes in handy every once in a while for things like loading apps, loading web pages, and playing games.

Seems to be a nice idea. But could you elaborate as on why the text is bold and you had to use capslock for 1/2 of it!?
@slind ok i fixed the post. i will be posting links to the posts who are great battery savers without loosing performance
So basically, we use an I9500 like an Ace or a Grand to get rid of heating and battery drains.. Andyou suggest that it won't result in performance loss. I'd suggest playing games that are more graphically intensive and not just Temple Run.. Try copying data from one memory card to another, or simply try running a Full HD Video. Also, check out web browsing or maybe multitasking, and you'll see where the performance dies out.
I think the fix should come in the upcoming releases of stock firmware by Samsung. By turning off a couple of cores, you're only going back a couple of years. I don't think I upgraded from the S3 to S4 for that reason.

everyone has there preferences and there needs in a phone. and there own settings. and this is a Battery discussion thread. we will be doing many performance and voltage mods, so everyone could choose the settings that suits them. now please dont post aggressive post like that, im not stupid. i know that my settings are very low.
but for my most played games and most used apps. it doesnt seem to effect my performance, so im comfortable with my settings
i had the phone for 2 weeks, happily showing off battery performance and then i asked myself again, why the heck i bought this phone in the first place? BECAUSE IT HAS REPLACABLE BATTERY!.. LOL.. how silly i am trying to squeeze that little drop of power out of the battery when I can double the battery just by getting another spare.
no need to turn off anything, no need to drop performance or screen brightness.. just pure enjoyment of the full potential without worrying battery problem.. just get a spare.

I didn't mean to be aggresive and sorry if you felt like that. All I mean is, there is a limit to which you can undervolt/underclock your phone without losing the functionality or speed. While underclocking to 1.0 ghz or 1.2 ghz sounds kinda normal, going all the way down to 800 Mhz and that too only on two cores is like running Galaxy Ace Dual Core instead. Why would I want to spoil my S4 for it?
That is all that I meant. And the phone is normally shelling out a good day's use in normal usage. Why bother so much about battery really???
My S4 i9505 came with MDE ROM from the factory, apart from doing dirty flashes over dirty flashes, finally someone came up with a recovery which is working. So i've :
1. Formatted system , cache , dalvik
2. Loaded in Djembey's stock slim deodexed ME2 ROM.
3. Using PimpMyROM, did some moderately less aggressive tweaks.
4. Capped the Max frequency at 1674MHz. Interactive gov, Noop sched.
5. Fully charged and unplugged.
6. Fully on 3G . Gmail sync for calendars, contacts, mail, keep, notes. Moderately heavy on Gtalk and Whatsapp. Browsing news and websites.
Observed 4 hours screen time.
Almost 15 hours of total usage + standby (This doesn't mean much, screen time depicts usage time more)
The phone still feels warmer than S2, under operation.
I've yet to try faux kernel yet, but i doubt it would get much better than this. The physical limit i feel is on the CPU, HD AMOLEDs, and the modem itself under normal usage.
Feel free to comment.
Hi,
hope you may be able to help. I have been trying almost everthing to increase the music volume as the s4 does not drive my senheiser headphones as well I would like. Is it possible to increase the gain through a kernel mod somehow?
Wow you're really random. This thread isn't even remotely discussing about the issue you raised.
Try the omega ROM thread, see if the functionality list includes volume hack.

How does one go about disabling two of the cores ? c:
Hi all,
I've had my Surface Pro 2 256/8 since release and all has been fine until (possibly) the firmware update.
Turbo Boost was working fine and the CPU was going up to its maximum of 2.6Ghz but it is now seemingly capped at 2.23Ghz.
I've checked in PC Settings, Task Manager and CPU-Z, the maximum that the CPU ever reaches is 2.23Ghz, as indicated.
Anyone else experienced this? I have tried all power profiles (Performance, balanced, Power Saver and there's no difference).
Thanks!
EDIT: Having used HWiNFO64 on the High Performance profile I can see that the core is limited to x23 which is producing the 2.3Ghz clock speed. It occasionally indicates x26 (2.6Ghz) for a millisecond before ThermMon shows that it is being throttled back to x23. So it appears it's not reaching maximum speed to keep the heat lower, why this has happened is still inconclusive..
Have you tried to change the CPU maximum utilization in power settings?

>I've had my Surface Pro 2 256/8 since release and all has been fine until (possibly) the firmware update.
You've answered your own question. One reason to cap speed is for battery life. That's what the latest firmware update provides. You've found the downside.
http://www.theverge.com/2013/11/4/5064026/microsoft-surface-pro-2-battery-life-firmware-update
So they cap turbo mode to increase battery life, given the SP2 is advertised as having an Intel i5 CPU with no mention of speed on the MS site I think they'll get away with it...

Well, in that case, the CPU shouldn't be capped when NOT running on battery power, should it?
There is also cooling to consider regardless of if it is on battery or mains. Although was heat particularly problematic pre-update?
>Well, in that case, the CPU shouldn't be capped when NOT running on battery power, should it?
As another noted, SP2 slicks never said CPU would be running at max spec.
PCs are normally more configurable. But if you enter SP2's UEFI setup, the only thing you can change is Secure Boot. MS is emulating Apple in more ways than one.
The cynics among us (guilty as charged) would say that MS handled this just right: Release the device with uncapped speed to get the best possible performance for reviews. Then afterward, cap the speed to claim "improved battery life" as well. If MS had capped the speed to start with, SP2 would be no faster than SP, and would get slammed hard. SP2 is already slammed as having minimal improvements over SP.
Reviewers aren't going to take the trouble to revise their reviews, and even if they did, not many people will re-read them. So, with this method, you can indeed have your cake and eat it too. Think of it as a more "legal" form of juicing performance tests without the explicit cheating that Samsung and others resorted to.

Anyone thats knows the difference between the CPU's will know that theres not a huge speed increase though, the only thing they should of done was stick a decent SSD in there, I've got an unused PX-256M5M sat on my desk that reads/writes at near on full sized 2.5" SSD speeds where as the mSSD's have always had half decent read and poor write.
Other than that what else is there to improve on, the camera perhaps as per the Surface2, battery life, check, the only other thing the Pro/Pro2 needs imho is more accesories, yes they are coming but should of been ready at launch imho, I'm crying out for a dock...
I just read this over on phonearena and wondered if anyone else saw it and has tried it.
http://www.phonearena.com/news/How-...-visibility-of-the-LG-G3-without-root_id58888
Im tempted to try it but hesitant too.
It'll increase the overall performance of the phone, at the cost of a little bit battery life, since turning off thermal mitigation allows the cpu to clock at a higher speed more often while ignoring the heat.
I cant decide if its worth it. For the most part I dont have any complaints about the brightness but I also use Lux.
While it was a different phone I did this same thing with my LG G Pro with no adverse effects to the phones operation in just over a year. It is still going strong in fact, so I dont fear phone damage by doing this but on this phone I havent seen the need for it yet.
I've been using this setting for some time now. I see no decrease in battery life, indeed I've seen nothing negative from it.

I've had both thermal settings off for a while now as well, it only powered down from heat once and that was because I was chrome casting Netflix and playing a intensive 3d game. Other than that it's fine, however I would expect it to get hot doing 2 large processes anyway. Battery life is still 4-5hiues SOT
By doing this my phone over heats and the turns itself off. Was running fine for a while with it on but I guess it was to much for the phone to handle.
Hello everyone
A few hours ago, Firmware Finder received .150 firmware update for C185 models. I personally downloaded it even though there was no change log and updated using Hurupdater. I had noticed no changes at a first glance but then i moved to settings to confirm that the phone had updated. It said GPU Turbo below my version number. I decided to check out a graphically intensive game I play called 'Honkai Impact 3rd' on max graphics and 60fps which would heat down the phone within a few missions and there would also be quite a few stutters when alot of special effects would be going on at the same time before. I can confirm that since the update that the stutters have been reduced but most importantly, the phone hasn't been heating up as much in game after an hour of playtime. Battery life has been noticeably better too as there is less drain for sure. This is just my experience, can't wait for everyone else to get it as well, so I can know what is happening (whether GPU Turbo is actually on or not). For now though, I'll be testing more games to see how the phone is doing but I'm liking this so far.
very good news
In China, there have been a lot reports of the phone getting even hotter, the battery draining faster and the camera being more sensitive to flaring (esp. in night mode). I'm curious if people here will confirm or if these bugs have been fixed in the meantime. Personally, I think I won't update to .150 when it's out, better to wait a few weeks =)
Better battery drain during gaming or even in general use?

From my experience (which is less than a full day) the phone doesn't get as hot as it normally did before the update unless I play extensively for about an hour straight. Any less and I've been seeing good heat management so far. Of course I'm still in the early stages of testing and cannot comment further until 3-4 days of testing.

So battery life definitely seems better when i was playing my regular games., I'll need some time before I can comment on regular use. I'll try updating the thread after a few days of testing.
Interesting news! Any antutu or other benchmark result?
Still waiting 130 update for C432 model of p20 pro.
Funny how some areas gets updates so much faster although same phone model.
What about normal apps specially Google photos. Is it any smoother with no lag or stutters ??
Hi, please check the slo-mo 960fps recording.... Any improvements in the alleged artifacts during 32x slow videos? Huawei is using framerate interpolation for it which throws in visible artifacts during close up slow motion...

For everyone interested to know benchmark results, to my disappointment, results on Antutu, Geekbench and 3d mark remain very similar to those prior to the update. Which is very strange indeed as I'm definitely noticing an improvement in battery life, device heat management and fps slightly whilst gaming. It is possible that im running a test build and have not been running a full taste of Gpu Turbo, and it's also possible that Huawei's claim of 'Gpu Turbo' just means much better device thermal manamagement for more consistent FPS and battery life. Lastly, it is also possible thst Gpu turbo isn't even on since this is a test build and it's just that they've tweaked device performance and improved battery life compared to the previous version I was on (. 130). Thus I cannot judge fully and I'm waiting on an update to prove me wrong. I check firmware finder everyday and love testing new things. Although if what I'm experiencing is actually gpu turbo then I do not mind as at the very least, I see some improvement in battery life.

Scrolling has been super smooth. Google photos has been super snappy. The only app I see causing any scroll lag at this time is Twitter and that I'd blame the app itself rather than Huawei. I think it's definitely more fluid than the previous version of the software I was on but it is not heavily noticeable as both were very smooth for the most part.

I took this opportunity to compare the slow mo performance to my Mom's S9+. I believe the artifacts are still present as I see lines and weird effects popping up randomly which I do not see on the S9+.
Gpu turbo is only for games so you won't notice any improvement other that in gaming, that's why there is an special application tor that "game suite" that you can enable the acceleration.
I'm running b150 for a few days and so far the phone is better from before in term of small tweaks here and there and i noticed the front camera is better now,not perfect but very usable.
The battery has improved a little but but it was very good before too.
I had read that the antutu would be similar to snapdragon 845. I guess it was just a lie.

Oh thanks for the info, I actually didn't notice this and yes I see games running much nicer with the setting turned on. However, they also heat up the phone quicker and drain alot of battery life. Should you choose to turn the option off however, you notice the same games don't drain as much battery life anymore and the phone doesn't heat up as much and the battery life is noticeably better than before the update.

That's pretty good considering you're gaming. I'm definitely getting atleast 7-8 hours of sot when I'm not going all out and about 5-6 on maxed out heavy gaming for most of the day. Even with the Gaming Optimization turned on the phone doesn't heat up alot as long as you're in a well ventilated environment. Im not much of a heavy gamer myself but definitely see better fps on Csr Racing 2 (used to lag a bit in the garage) and Honkai Impact 3rd with optimization in gaming suite on. Honkai is definitely giving me 60 fps in 90% of the scenarios so the lag is barely noticeable unlike before. As for benchmarks, unfortunately you cannot add benchmark related apps to the game optimize feature so the GPU turbo can't be turned on for them. Strangely enough, every other app (even regular apps) can be optimized.
