"sleeping" CPU cores...normal? - Moto Z Questions & Answers

I have a Z Force Droid, but I'm gonna cross post this here since both phones have basically the same hardware
Last night I was just messing around and looking at some things trying to figure out the issues with choppy scrolling on our phones since the update and was checking out CPU usage and noticed something interesting...
I saw that two of the CPU cores were being reported as "sleeping" with no activity registered on them...even after running a benchmark there was no activity shown...
A reboot "fixed" the issue and all 4 cores were reporting activity...but then after going to bed, and waking up this morning it is back to the same...I attached a couple of screenshots to show what I'm seeing. You can see in the second picture the "history" clearly shows where the two cores went to sleep...

As mentioned throughout these threads the choppiness is caused by moto actions swipe to shrink.
If you turn it off it goes away. It might be the Apps you've tried when I tried it using the system panel app it shows all 4 running but cpuz only shows 2.
What are you getting for your benchmark scores?
That is the best indicator of if there is a core issue.
I get around 159000 on ANTUTU and that is with aida64 saying 2 cores were sleeping.

It could very well be the apps themselves, but there is certainly something causing them to read differently...
For example...with the phone sitting overnight, CPU Monitor reads like this...nothing I do can get the bottom two graphs to register...
But after rebooting the phone it reads fine...as you can see here...
Now after rebooting and running AnTuTu I can get this graph to show all of the available frequencies...up to 2150
But once those 2 CPU cores go to "sleep" even after running a benchmark nothing above 1593mhz will register as ever being used...
It could of course be an error...but if it is, every single CPU Monitor app I've tried (about 6-7) reports the exact same thing
You're right its probably the apps not reporting things correctly, as my AnTuTu scores are up over 150,000 so I would imagine if cores were not being used it would be much lower...bit it's still quite odd

This is what I get using 3 different apps the 3rd one is called SystemPanel and it always show the cores as active

That's the only reason I asked, it just seems odd, that's all...
For the record, SystemPanel does show all 4 cores as being active even though other apps do not...but it also registers the CPU max frequency as 1593mhz instead of 2150mhz...idk...just weird lol

Yeah I just noticed that as well with systempanel.
But since ANTUTU gives the proper score I'm thinking the cores are doing what they are supposed to.
I'm just glad someone figured out what was causing the screen studder.
That was driving me nuts lol.

Hi, i know it's necroposting, but i've come across this thread and have used the app for a short time, but i have a big concern about security with this apk.
I find this app beautiful, but isn't it a big security threat?
Look at the permissions (screen)!
And what's more - my AV detected it's a trojan...
Does anyone know a similar app with cpu usage history by cores (not only one "overall" chart, but each chart for each core)
and safer, without so many permissions?
I'm not an android expert, but i think there are way too much permissions for the job,
look at CPU-Z, it also measures cpu, but needs only... one permission (network - full network access) !
The CPU Monitor is a cpu measuring app, why does it even need anything with Bluetooth ?
Or reading sync settings?

Other than that it is always set to 816/216.
I usually get about 5 hours screen time and about 20 hours standby. Email and Calender sync at 1 hr, with a custom power profile that turns data off after 15 minutes between 3a-9a. I'm happy with it

Your profiles are similar to what I use, although I don't have one for charging/charging A/C
Also, you run 816/216 rest of the time? Aren't you short-changing your phone's capabilities a bit though ... ? I find the biggest different is having screen-off profile.

Not really. I change it to 1000/216 if it's spectral souls, gun bros or a benchmark. Angry birds plays on my fuze (lol) so i don't change it there. I have noticed little to no difference running 1000/216 on launcher screens, pictures, data rates or anything versus 816/216. If i bump it down to the 700 range then things get laggy, but as it sits 816 runs everything almost flawlessly.

Good to know, thanks! I'll try that, maybe squeeze out a little more battery life than I am now What are you averaging? I can go about 1.5 days with good usage as it stands
Strange, I can't have more than 15 hours if moderate usage...
I have similar profiles to the screenshot posted above, but I don't have one for when powered. The main profile on mine is 1000 max ~400 min. I've found that keeping the min ~400 makes the device always snappy without sacking much battery life.
I also use JuiceDefender to manage my data syncing. I leave the blur battery profile at high performance.

Depends on the day. If its a day off, i get ~30 hours with ~6 hours screen time from 100%-10%. Most days though i don't notice much, I drive around a lot listening to pandora in my car dock so its constantly being charged
If I can tear myself away from pandora for a day i'll repost something more meaningful.
On a side note, I notice with circle battery widget I usually get the slowest drain between 80% and 40%, not sure if anyone else has noticed this.
Small update to what I said earlier..
With my profiles, and all the crap running in the background this is what i got now from 100%-31%
1d3h11m since unplug
1d0h25m idle time
3h04m display
0h45m spectral souls (!)
Would go further but I am gonna be away from a charger all day tomorrow
i get the same battery life with setcpu and a display off profile than with no setcpu at all. my guess is that the battery saved gets wasted on setcpu itself.
I have the phone on from 7:30am to 12 midnight with no calls and 1 hour display time and i have just 40% less. No wifi at anytime.
Apps i only have gmail, no other email accounts, twitter at 15 minutes and whatsapp

You got something else wrong. SetCPU will definitely not drain the life it saves. you must have a beast app running in the back somewhere...
also, what kernel/rom are you running?

i get like 12 hours in my normal day i guess its to few :s but streaming music over BT like 4 hours and surfing web forums tweetdeck. not impressed battery for my usage :S
perhaps seems better than my N1. and seems when i enable data it drain more faster like 5% per hour screen off, and no data like 1% or 2

Yes, my question was pretty straight forward...what kernel are you running. From your response I see your English may be the issue here.
Anyway, reason I ask is because some kernels such as BFS kernels don't really play nice with my phone nor battery. So maybe the issue is with the kernel being used.

/sigh. XDA, a wealth of information, but a lack of patience and reading comprehension.
Anyway, I feel like the Atrix does better than the Evo with battery life. I might try fiddling with SetCPU, so thanks for the info.
HTC Desire with stock Froyo ROM
I've been using SetCPU 2.1.1a recently and have noticed no difference in battery life. Is SetCPU a placebo as far as battery life is concerned?
My settings:
Charging = Max. 998 / Min. 998
Screen Off = Max. 245 / Min. 245
Battery < 101% = Max. 998 / Min. 245
Battery < 25% = Max. 499 / Min. 245
If I "Disable Perflock" SetCPU says "Success: Perflock appears to be disabled".
Some say it increases their battery life, are they imagining it? I'm not interested in over clocking. I'd be very willing to buy it, if it increased my battery life. Thanks
Why are people using Setcpu to try to save battery life?
The whole point of Tegra 2 is ultra low voltage operation when the system is inactive..
Its absolutely counter-productive to use setcpu to try to already do what the chipset itself is made to do and not half as effectively.

This thread is covering more than the Atrix. I didn't want to start yet another thread about this, when there are already plenty. Besides the main SetCPU thread (with the download links) is in the HTC Dream section and that phone's ancient.
If someone can answer my questions please.

[Q] CPU Temperature overheat level?

Hey everyone...
So today while i was trying to download an app, my cpu temperature became 63C (145F).
I was wondering if this temp is even possible and what the temperature the phone is set to turn itself off at.
EDIT: Moto Atrix btw, tegra2 processor
I'm not sure about a mobile processor, but a desktop processor can well above 70, 80, or even 90 under heavy load.
63C sounds wayyy too high for a low voltage/power mobile cpu. Then again its hard to say, as the mobile chips are passively cooled.

thats your battery though, i am talking about processor.
I wopuld assume that this temperature is damaging to phone itself, i just wonder what the overheat level for the nvidia tegra2 is.
hmmm, still very intrigued. part of me wants to runn my phone as hot as it can till it over heats and reboots, and part of me is saying im a dumba** for even thinking of that, lol.
EDIT: just wanted to say im running greyblur, if that affects anything at all, lol.

I probably know more for hardware than software, don't feel bad, lol
But, actually, overheat status isn't true overheat function. When there is a true overheat, the phone either turns off or reboots itself. When the battery becomes too hot, the processor ignores that in most cases, while if the processor itself gets hot, it shuts itself down.
Yay, my first true member post, not junior anymore!!!! hahaha
I am also getting these high tempuratures on my cpu and not my battery.
My idle tempurature lowest was 35C and averages 55C and my highest was 70C and averages 65C. I really need help on how to fix this. My battery temp is around 40C
I set up a SetCPU profile so that if the CPU temp reaches 60C, it will max out the processor at 750 Mhz. For me, it pretty much cools off instantly. You may want to set yours lower. It doesn't reach that level often.
I've started a thread early today regarding the atrix's heat issues. Soon as I started playing games on my Atrix I got pretty scared with the temperature I felt on the exterior, and more scared after using temp. monitor apps.
http://forum.xda-developers.com/showthread.php?t=1249757
The idea is to mod the phone to help dissipating heat. Besides undervolting with setcpu I guess there isnt much that can be done at software level to reduce the main chip's heat.
The ideas are still being formulated. I opened the thread so I could get some help and suggestion from other atrix owners, to have a good idea of what to do when I finally open my phone
If anyone wants to try it or have any ideas, please comment there!
WolfFX, your link has actual "...." in the URL and doesn't work.
Regarding maximum temperature before shutdown, I'm wondering if anyone has EVER seen their phone shut off due to high heat? Does it even happen? I'm not meaning reboot either, but actual shut down to cool off.

Yeah. Left the screen to never time up and setcpu to stress test. Left it on my bed covered by a pillow (accidents do happen, I'm quite forgetful and idiotic). Came back and the phone was in "emergency cool down mode"

Guys, I will repeat this just one more time. DO NOT let your CPU temperature get higher than 50C... Constant minor overheating causes long term damage to your phone, shortens it's life span.
One major overheating can toast your phone just like that.
These aren't desktop PCs, use common sense. Overclocking to higher than 15% doesn't come unpunished.
Also posted the same in the other operating temperature thread.
Did a bunch of looking around and after a while found some white papers with the following temperature ranges:
General operating temps of -40C to +85C.
Practical usage will start to drop off below -20C and above +70C.
This tells me that our safe operating range should be limited to the practical usage temperatures. Anything outside of these and there is a good chance you will see performance drop off fast, and also may suffer hardware lockups, etc.
Personally I will stick to +65C which is the rule of thumb I go by with my PC's under full load.
<edit> I would also add that while our phones are not desktops/laptops/workstations, the CPU's can all handle around the same temperatures in all devices. Materials used and manufacturing techniques are almost identical. The solder used has a melting point of around 180C - 190C, so there is no fear of melting the solder. The main difference is that phones do not have active cooling, so you will see much larger jumps and swings in temperature. This being the reason you cannot OC in the extreme ways you can with PC's.
i read a post somewhere that 75 degrees c was the max it should go to, anything higher is way too much
I read somewhere that if you overheat yer phone it eventually breaks. Pretty much it. Just don't let it out in the sun too long or anything silly. However, keep in mind that if you do break your phone, you can always donate it to XDA. I think they're looking for bricked and broken phones.

Mine gets above 50C, and usualy around 57C, every time I open any kind of game... Should I be worried?

[REF] My phone is getting really hot, how hot is too hot?

A number of people have had their phones get very hot and wonder, how hot is too hot?
The purpose of this thread is to answer that, as well as be a reference that can be linked to for providing a quick answer.
Before anything, download a temperature app so you can see exactly how hot your phone is getting.
Once you have that, continue reading.
People have reported phone temperatures being a hot as 100° f to 110° f (~38°c). That is hot but not that bad. Upper 40's celcius (47°-49° ) is not good. And 50°c is critical And can cause damage, even though 70°c is considered the 'kill' temperature for lithium ion batteries.
There are many reasons this could happen. The majority of people notice it after flashing a custom rom to their phone. This has been reported happening in many forums, not just this one. On the whole, people find that when this does happen after a flash, it usually occurs once or twice, and then does not happen again. There is no clear explanation that I know of that can explain it. It could be the phone 'relearning' or adjusting to the battery. It could be an app that is not working well with the new rom. That is why rom developers will sometimes say to not do a titanium restore on all but your most important apps, and to download the rest from the market. It makes for less chance of an app not working well with the rom.
'Rogue' apps are many times also to blame. A rogue app can be described as a malfunctioning app that is improperly working and as a result causing high CPU activity, which in turn causes the phone to heat up. It also can be a bad app that should be avoided, at least until the issues it has are worked out.
How to fix that is usually on a per phone basis, meaning most cases are unique, and what works for one may not work for another.
There are apps that can help track down the problem app. One of the better known apps is better battery stats.
https://market.android.com/details?id=com.asksven.betterbatterystats
Check here for a better explanation of it and how to understand it:
http://forum.xda-developers.com/showthread.php?t=1179809
It has also been noted that using internet browsers cause the temperature to rise roughly 10°f (5°c). So if your phone is running hot, stay off the browser, it'll just make it worse.
However, while you're trying to figure out what the problem is, your phone may be overheating, or at risk of overheating. And a quick way to shorten the lifespan of electronic is to be too hot.
The first thing I recommend doing is downloading SetCpu.
https://market.android.com/details?id=com.mhuang.overclocking&hl=en
Once you have it, or a similar app, downclock the CPU to 500mhz, at least while charging it, to help keep the temperature low in case an app spikes CPU usage and you're not there to stop it.
Sometimes even flipping the phone so the back is exposed is enough to cool it down.
Keep in mind most electronics have solder that will melt between 120° to 180°c (248 - 356 farenheit). While your phone should never ever get close to that, 50°c pales in comparison. But it can still damage the battery.
I also recommend SetCpu as you can setup a profile for it to run your phone slower when it hits a certain temperature to help keep it cool. As well as sound a notification that it has past that temperature.
Charging your phone will raise the temperature of your battery, it just does. At times it may feel very hot. But again, use an app to see exactly what the temperature is. It's not uncommon for a phone to heat up to over 40°c while charging. Though 39°-42°c is towards the high end of what is acceptable, it's relatively normal for charging temperatures.
For my phone I have a SetCpu temperature profile set at 44°c. I'd rather catch it before it gets even close to bad.
Feel free to post about apps that have helped you to narrow down a problem that is causing your phone to get too hot. As well as any experiences you've had with overheating and the steps you've taken to stop it.
For some reason, I've pinpointed browser use to cause my phone to get EXTREMELY hot. I've tried several different browsers, all with the same result. I will download a temperature app and report back.
UPDATE: I had just been using various apps on my phone for about 30 minutes, and the temperature was at 95 degrees. I then used the browser for 10 minutes and the temperature jumped to 104.
What browser? Dolphin browser has been reported by a few users to cause high cpu use. No cause was pinpointed so far.

Does it jump when using any of those browsers or just certain ones?

All browsers I mentioned cause a jump
Thank you for checking. I'll add it.

Just played one race in Asphalt 6 HD and phone was wicked hot, did not have a temp app to check actual numbers.
What temp app you recommend?
Battery indicator pro is awesome. One of my most used apps. Data pack is almost done downloading for asphalt 6 on my phone. I'll post what temp it gets to.

Just played asphalt 6 and dang it's fun! My phone is running the latest unnamed rom, entropy512's 1212011 kernel @1.2ghz max, wifi on (though looks like juicedefender shut it off during the game, could account for the game crashing) , not plugged in. Game ended up crashing while running the kernel on conservative. Changed it to ondemand and had no issues.
Before starting the game my phone was at 29°c

Not too hot, but a definite jump. As good as the game looks and as smooth as the gameplay is, I'm sure the temperature will need to be watched as with most high end games. I'll report back if I see any temperature spikes.
Update: played 5 races in a row and got warm, but not too warm, 41°c
Final thoughts:
Buy this game!
And xda app gave me two choices for quality on the screenshots I posted but wouldn't let the higher quality one upload. Said incorrect extention.

Mine has been getting hot lately too. I haven't identified any battery drainers as the cause, but when my phone gets down to around 25% batter lice the phone starts to heat up. Like today, I pulled the battery at around 20-30% because it was getting warm, waited about 10min for everything to cool down, put the battery back in and it was down to 3%. Either something we're running is causing this or there are battery issues starting to develop.

I did not, i was concerned about damaging the phone. I will the next time around. Thinking about buying a new battery to see if i have the same issue.
Use cpu spy. My phone does the same thing. Occasionally it gets stuck on 1.2 ghz, and really heats up.
Pulling the battery resets it.
I haven't been able to figure out what does it.

S3 is hot. I mean, it's hot! 3 mins on homescreen

So I recently went around, frustrated with first public 4.3, rooted that I had installed, installing some custom roms hoping for fix to stuttering with music and all this good stuff. Tried Android HD 50 and noticed my phone gets hot. Now every time I installed a rom I noticed that the phone tends to get hot on first boot cycle. I will boot off for 5 minutes, let it cool off, launch again never notice the same.
Now it seems to be permanent, and I installed 4.1.2 as last resort and it even happens with the official, pre 4.3 rom.
Simply put, the phone heats up, starts heating from just waking up the screen. Apparently according to better battery stats, the phone is MAINLY running at 1.4Ghz, even when just in homescreen or whatnot, instead 800Mhz. And the phone is heating up considerably in ANY use, be it me booting it, flicking some settings and that's it.
I was wondering if anyone else had experience, or if this is known and there is a fix? (Did not seem there was lot of threads about this).
CURRENTLY; I am running rooted, newest official 4.3 in NEE range UGMK6, rooted.
As current workaround I enabled power save mode for CPU limit only. Since I pinpointed the reason for heating up probably, but not why the phone wants to go to 1.4ghz for just the simpliest task.
Thank you already, even if this thread gets closed and I get told there was already discussion of this elsewhere (which the search did not pinpoint to me)

It's almost 2 years old. about 20 months more precise. Been dropped maybe few times, no screen shatter no nothing but mostly some plastic stuff.
This is somewhat recent phenomenom though.
Have you tried installing a custom kernel and limit the max freq ? Also the governor, as it seems to be "Performance" in your case. This governor keeps all 4 cores online, all at 1400mHz. Try @googy_anas 's GoogyMax2 kernel. You won't be disspaointed (it works for both 4.3 and 4.4 ROMs, so it is easier to install).
Heat can be generated by the cpu or battery, sounds like your issue is with the cpu. If you have already tried a full wipe and official firmware then only hardware issue remains.
Either the cpu is damaged (ever overclocked it?) or the BGA connection to the motherboard is fatigued, causing high resistance and heat.

Never overclocked to avoid possible damage and heck, it's s3 which still is pretty powerful handheld even today.
As for fatigued connection, possible; would that show up as cpu being at maximum clock rate all times? According to better battery stats, like said, my cpu is at 1.4ghz (1.0ghz in cpu power save mode) almost all of the time the scree is on. And I do not know if that is necessary for just homescreen or browser without much media content.
I would hope I do not need new one, the phone's completely paid in 4 months.
There should still be warranty if that is called for.

Can u check ur governor?
Sent from my GT-I9300 using xda app-developers app
I was having the very same issues but only on certain ROMs. Stock ROM was a killer for me, during intensive browsing the machine was like a small heater. I decided to switch for CM and I had pleasant temps with that. Not so good experience with OmniROM. Finally I stayed with temasek who has an excellent ROM, i also managed to undervolt the CPU and GPU (and tweak the GPU stepping only to use frequencies in the 54 - 200Mhz interval) and not to use high frequencies (1200+ Mhz) via boeffla kernel settings. and since then, I have never had temp issues. It is quite amazing to see that the phone is able to decode a 20Mbps bitrate movie fluently @800 Mhz with only 2 cores active and 108Mhz GPU step.

Yeah... well I spent last few days "re ROMming" the phone left and right and not against experimenting this at all.
Though, for me I can notice the heat in minute from opening screen and launching browser or something like that, and in two it is already REALLY hot, Nothing I would call even intensive on stock already makes the potato in my hand noticeably warm, bot back and touching lower part of the screen...
And I am not exaggerating with the wording, I wrote this post on my cell and now it already is hot as 30min session of GTA or something.
My cpu ticks over at 300Mz when idling with screen on, see the attached. This is with all power saving options on. If yours is jammed at 1.4Ghz then either the kernel is corrupt (but you've reflashed) or the cpu has an internal issue.
Almost any app use will cause the cpu to jump to max frequency, so that doesn't mean anything.
All silicon is different, if yours is borderline specs then it may get warmer than another -provided the battery remains below 50 °C then no problem.

I think my battery swims in 40-46 celcius after a while of device just being open. 1.4ghz is normal ok, but why the excessive heat then. And two years ago I hoped i needn't to get another phone in at least three years since all I do these days at maximum is twitter and youtube on my phone. No games or anything...
And - at least to me noticing it this is recent. And I would since its hot enough that i feel it in my thigh after putting it in my pocket.

Being at 1.4ghz all the time is the reason why ur phone heats up. So it is not okay. I think u btr send it for repair since it is not software based.

I have had the same issue with my S3 (SGH-T999). What I found was that the overheating occurred with a certain battery in use. Yes, I carry 4 batteries around with me. The oldest battery seemed to be giving me the problem with frequent overheating and a lot of reboot/shut down issues.

I have two different batteries, this happens on both, extended and the normal one that came with the phone, so I eliminated that idea too.
Well bummer. Sorry I couldn't help you better. Do you use a full body screen protector with a case? You may also want to clean out the inside of the phone, under the casing. After almost two years the amount of dust and lint can really build up.

If your cpu is constantly running at 1.4ghz then that should be the first thing to fix. You can try to figure out what is causing the massive cpu load by installing a cpu monitoring app from the playstore.
If this is a hardware related issue, then you need to get it fixed. In either case, constantly high temperature can affect your cpu permanently.

If your rom is screwed. You'd rather perform a mega-wipe and flash stock nb6 firmware through desktop odin and see. I would give some time for it to settle and compare the temps.

I think Poco has underclocked my CPU!

Hello,
I have been noticing my pocophone beeing sometimes laggy (so laggy that I think of throwing it into a wall) and sometimes, it freezes for few seconds (sometimes, I even have to force reboot it),
So I decided to try few things,
I started monitoring my cpu clock, and doing some benchmarks.
as opposed to the scores on geekbench 5 website, which are respectively 438 and 1745 for single and multi core performance, I get only 300 and 1096 scores!
as for the clock of my cpy, it never surpasses 1.8 ghz, while the advertised clock of the cpu is 2.8ghz!
Also, the performance cores rarely go higher than 576 mhz, even during benchmark!
Note that my device is fully stock (no root, locked bootloader, with the latest global update installed, android 10, miui 11)
So I am wondering, are you guys getting those scores or is it just me? and do custom roms have the same issue?
If this is caused by XIAOMI Software, I think this is totally unacceptable!
After recent updates antutu and geekbench scored declined, poco is doing underclocking cpu to make users force to buy new poco phone....it is really disturbing....i actually gonna root my phone and install pixel rom.
The Miui kernel of Pocophone F1 is capping the CPU at 2.09 GHz, I really don't know why but I think it's something to keep it cool and to enhance battery life

Yup! It all depends on temps. It will throttle more as your phone gets hotter. If you live in a hot region there's nothing you can do. Just try to use it in cooler environments. And overclocking on mobile devices is not efficient. It is just there to tell you that you can.

Totally agree, but even if the phone is cool and the room temperature is 16 for example, the Pocophone F1 won't go over 2.09 GHz!.. This limitation made by miui kernel, no matter how hot or cool the phone is.

Even though I have never stayed on miui for over a week, I never had these issues. Wierd.
Well if the bootloader is locked only thing one can try is formatting the phone.
So I have charged my phone all night, and it seems magically fixed! (spoiler alert, not really)
It seems like it is a battery issue, under a certain battery percentage, miui will cap your cpu, even without turning on battery saver! because now, my cpu gets to 2.6 ghz, but still, the phone is so laggy, sometimes unusable laggy, as if it didn't have a flagship chip in it!
I have tested and I completely agree that the CPU is highly dependent on Battery Level. Even while plugged in (while low) the CPU scores are lower than should be.
But anything above 60% and you get what you expect. I'm assuming they are using the Apple version of extending battery life where they throttle CPU to make a dying battery last a bit longer. Remember that battery loses 10% first year, 30% second year and significantly more the years that follow.

Yup. MIui shuts a few thing off on low battery regardless if you have turned on battery saver or not. GPS is one example, I don't get location below 20% battery even if I'm floating next to GPS satellite.

Either way, whether CPU or Battery, it isn't normal temperature and it completely explains why he's facing the issues. It's normally around Summer where most posts like these begin and people don't even take into consideration that factor.
I can confirm this. MIUI kernel is limiting the performance factor by a huge extent. On latest 11.0.9.0 ROM the big cluster is capped at 1.8ghz even when phone is kept next to air conditioner and fully charged.
After flashing a custom ROM or kernel, the issues disappeared. Phone performance was back to buttery smooth and no throttling even in 35C ambient temperature.
Yes i had the same issue. As phone became laggy, i became frustrated.
Unlocked the bootloader and flashed a custom rom and kernel.
The device now so smooth and free. I am loving it now.
If you want to stay on MIUI(but i suggest you use PE10+ rom), and ok with rooting, do it and install some kernel manager like FK kernel manager. Now you can clock your cpu and gpu as you like. Overclock it when you are doing some intensive gaming or underclock it when you want to save battery. Moreover now you can charge your device faster. MIUI limits the charging volt/amph but you can change that too. Advance Charging control App helps with that. It can charge up to certain % which you can set after which it automatically disconnects charger so leave your device connected to charger and it won't harm your battery.
If you do it and it helps then thank me later?.
