[HTC One X] Shan89:
Hello everyone i know there are few threads about battery/gaming so i tought to make a thread with a review about battery life + gaming performance and add guides along with it.

Ok 1st i'd like to say i've pretty much flashed every single rom ,kernel, battery saving apps, performance boost apps, mods etc that are currently avilable so trust me i know what i'm writing here.

Kernel reviews @ Post 2

========================================================================================[/CENTER]

- If you'd like to donate to any of these ppl please do so because they're the ones who made this possible, i'm just making it simple and hopefully preventing questions from everywhere about battery/kernels/roms , which is the best etc etc. And remember the kernel is most responsable for your battery life. So the point is you can use any rom of your choice with this kernel as long as you do things right. And follow what i wrote down there.

As for me i'd be happy just with simple *thanks* button if this was helpful to you in any way.

------------------------------------------------------------------------------------------------------------------------------------------------

ROM, Kernel, Undervolting, underclocking, overclocking settings:

ROM Settings:

​

Roms should be cleaned with RomCleaner tool just i used my own scrip since i wanted to keep some apps and widget, after cleaning i had 114 system apps on my hox , Renovate rom comes with around 200 or so + the apps you'll install. (rom cleaner also improves the battery and rom speed a little) Other then that nothing else changed except i added tons of mods but thats up to you what you'll add. And the only setting you'll need to enable in Renovate rom is 2d rendering This improves alot scrolling times in apps especially the ones like *Advanced system care and Rom Toolbox lite*​

Kernel settings:

​

Battery settings​

the only thing you'll have to do manualy is switch the governor after flashing Xm kernel onto Smartmax And thats all you have to do to have great battery life, in my case i underclocked my CPU to 1200mhz with smartmax governor + RoW scheduler , if you want to keep it faster (but you don't really need any more speed with this governor) leave it as it is, or to make it even faster use Smartmax + deadline + sampling rate 30000 + touch poke freq 1500000 ] , you can make it even faster but trust me no need for that. Use this governor and it's settings as daily settings for light tasks and light usage of your phone.

Gaming settings:

​

​

​

For this you should be using interactive / gaming governor + deadline scheduler and that's all you need to do of course if you do underclock your CPU make sure you reset it back to 1500 after you change the governor , no need for apps that boost your phone, if you wanna make things even faster and governor more aggressive change this value in governor settings : go max speed load 45 this will increase speed ( remember this will make battery drain even faster ) , and if you wanna push max performance that your hox can deliver at current time change min frequency 1500 as well remeber THIS will make your hox battery drain fast as hell ! And sd card read ahead speed should be 4096 if is not set like this by default you can use system tuner and change it. For tuning governors and freqs you could use SetCPU easier and faster to do so.

Games that i used for testing are

:

NFSMW, MC4 , Shadown gun deadzone, Wildblood

.

Each of this games were incredibly smooth and playable like never before.

Undervolting

​

Ok so as many of you heard undervolting should improve your battery life and it does by maybe 5% tops 10% if you're lucky.

But the main reason why i undervolt is so i keep my phone cooler when gaming you wont notice big difference in avarage daily use without gaming but with gaming you should notice the difference but again this mainly depends on your CPU variant, in my case i have variant 3 which means i can undervolt more then variant 2-1-0 , thats the only good thing about undervolting , of course i could overclock more then other variants but we don't need overclocking with this kernel and rom.

The difference and battery improvement you'll be able to see only this way really and none other this is how : without undervolting and lets say playing NFSMW my phone ON charger reaches around 55c TOPS ( which is overheating and you lose more battery then what your charger can recharge for you ) but with undervolting my phone is reaching TOPS 45C and avarage 40C ( this also depends on the room temperature and your hands body temperature ) The reason why i did tests on charger is because thats the fastest way to test overheating and undervolting and NO do NOT play heavy games while charging this is KILLING your battery and lowering it's life cycle ! it's like eating while sh1tting !!!

Now i can't tell you which values to use since like i said above none chip is the SAME nor the variant so you'll have to figure out this on your own but i can give you the

ROUGH

idea

how-to.

Update - rough idea how to undervolt

​

CPU

​

properly:

​

ok i'll mark frequencies with colors:​

Before we start remember this: Undervolting depends mostly on your ROM , Kernel ,

USAGE !

​

RED =

Don't undervolt too much

BLUE =

Undervolt normally as you do

BLACK =

Don't undervolt or undervolt just a little this will depend on your variant and rom mostly

1500+ , 1400,1300,1200,1100,1000 e.g 1500mhz freq. has 1237mV by

default

if you're a gamer you can undervolt this one to lets say -50-100 (up to the variant) if you're not a gamer you can go even up to

-125/150

, now this can depend also on which freq do you use the most in gaming lets say , if you're using

quad lock

e.g 1500 , -75 should be enough, === freqs under 1500 can be undervolted more since they wont be used, but if you don't use quad locking then you need to balance the undervolting between -50-100 (this depends on the game and which freq it uses the most)

860 , 760, 640 are the freqs in the *middle* those can be undervolted even more , up to -150 (default UV should be around -100 here) since they are barly used but you can use cpySpy to check which freqs your device uses the most and then use that info to balance your undervolting and find right freqs.

475,340,204,102,51 are the freqs more like *screen on standby freqs, mostly 340/51* or the LP core freqs, these should be undervolted MAX -50/75

or not at all

these freqs are used also for e.g. listening to music while screen off , if you undervolt too much you can experience laggs etc.

Important: Variant 3 can undervolt more then this but it *shouldn't* really up to you to decide​

IMPORTANT: Those who use XM kernel USE TRICKSTER MOD APP ONLY !

First of all you can use guide what i made above for undervolting but since we have accurate undervolting now you SHOULD undervolt THIS way and this way only:

Variant 0 = you can use undervolting max up to -50 MAX ! or if you're doing step by step undervolting you might push some freqs -75

Variant 1/2: You can undervolt MAX up to -75 or at some steps -100 tops.

Variant 3: you can undervolt MAX -100/125 and on some freqs MAYBE -150 , but of course you need to do step by step.

Remember: this are the

SAFE

undervolting values for all

4 variants

You can try undervolting more if you like but i wouldn't recommend it since i'm sure it will most likely cause issues for you.

Remember: The UV values i've used above are supposed to be *DEFAULT* uv you should use , but users with

variant 0

MIGHT

suffer and have to use lower values

Note: I guess 90% of ppl are lazy to mess with per freq undervolting and finding what works for them and what not since consumes alot of time, anyway you guys should be good with -50-75 variants 0, 1 ,2 , as for variant 3 you should be able to go up to -100-125 on all freqs.[/SIZE]

GPU - Undervolting - Safe values

​

[*]Ok so for GPU undervolting you need to be on XM #153 kernel and above and follow this steps:

Use some root explorer to enable GPU undervolting and navigate here:

, open it , the default value is

and SAVE make sure to enable *system as writable*

After you do that you need to download this app from playstore *Trickster MOD* This is the ONLY app whit which GPU undervolting works for now. After that install app and you'll see GPU freqs like this: For e.g. *520000, 484000* etc those are the GPU freqs and their voltage.

The safe values:

Variant 0 = -25MV on all freqs.

Variant 1/2 = -25/50 on all freqs.

Variant 3 = -50-100 on all freqs.

The 1st freq i wrote is 100% safe, the second is ASSUMED to be safe as well, but you wont know unless you try it :cyclops:​

How to test are these values safe and wont freeze/reboot your phone.

​

Probably many of you know when you undervolt too much your phone eventually feezes and reboots this happens because phone can't give enough of voltage to the certain frequency that is in that time used mostly so it has no other way out but to freeze and reboot. and the way to test this is it *safe* is either to use *antutu bechmark app* , *epic citadel* or *stability test* Those 3 tend to push max performance very fast and easy out of your phone so if any app gonna show you is it safe it's these , tho sometimes but rarely your phone will run them both without reboots so i suggest you do each of them 2x just to be sure, and even if then sometimes very very rarely if your phone doesn't reboot the last way you could've find out is it gonna reboot is by playing NFSMW for 10mins.

----------------------------------------------------------------------------------------------------------------------------------​

GPU Overclocking & underclocking - Safe freqs

​

For this to work use some root explorer and navigate here: sys/devices/system/cpu/cpu0/cpufreq/gpu_oc , open it there you'll see default GPU freqs like this: 520 520 520 520 484 400 304 267 247 those are the DEFAULT freqs on XM kernel and make sure to enable *system as writable* before you start doing anything. Those freqs are great balance for GAMING and BATTERY but if you're an ADVANCED USER you might wanna make those freqs EVEN HIGHER for better performance (not needed imo ) or LOWER for better battery life

- Maximum performance freqs that works for everyone: 560 560 560 560 560 484 400 304 247

- Freqs for battery life while keeping some poor performance (gaming speaking): 304 304 304 304 304 304 304 304 247

- Default freqs ( battery & gaming ): 520 520 520 520 484 400 304 267 247

Thx to Neo for this freqs. ​

Thx to Xmister for this.

=======================================================================​

Remember you wont probably get same screen on time as i did , you could get even more then i did or less, it ALL DEPENDS on your USAGE/Screen brightness!

That should be all enjoy.

-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------​

The screenshots and my usage are in post 2, hope this helps , if not sorry for wasting your time if you read this , cheers and good luck to everyone :)

If you have any question please feel free to post them and i'll give my best to answer them.

Also as the kernel updates and rom updates go i'll try to update in here as well.
