[ROOT] Change CPU temp. limits ("Manage" overheating) (Updated 10/11/15) - Sony Xperia M4 Aqua

**** Update 25/1/2015 Add No Aggresive 2.0 Mod
By FirstMn
This "mod" help can you with CPU Overheating in Sony Xperia M4 Aqua, but remember!
1) You are installing it, and its your choose. That mean you bear full reposinbility for your machine. I dont have any duty or reposinbility to your device.
2) If phone, or parts of phone (sd Card, SIM, CPU,..) will break, read 1)
3) My work you can share, copy, edit, link. But if you write me as default creator, it will be good.
What is best? For gaming it is Performancefriendly.
For lower heating it is MinimumOverheating.
Other mods are things like experiments..

---- Types of mods
----
1) 26.1.A.2.167_Original (MOST STABLE)
In short: Original settings from Sony
Original CPU managing from system. Useful if you won't backup original files or not like these mods.
CPU temperature range -> CPU clock:
Original:
.SMALL cores (up to 1.1 GHz)
65 - 70*C -> 1136 MHz
72 - 77*C -> 800 MHz
75 - 80*C -> 800 MHz
79 - 83*C -> 499 MHz
85 - 95*C -> 200 MHz
.BIG cores (up to 1.5 GHz)
60 - 70*C -> 1136 MHz
72 - 77*C -> 960 MHz
76 - 81*C -> 800 MHz
79 - 84*C -> 533 MHz
85 - 95*C -> 400 MHz
GPU temperature range -> GPU clock:
Original:
55 - 60*C -> 400 MHz
70 - 75*C -> 220 MHz
#Original ranges and clocks is written in all your files. It is not easyiest way to open these two files in your /system/etc
---
---
2) Performance friendly (STABLE)
In short: High performance stay for longer time, but phone gets hot.
Max. CPU temperature is 90*C, more is starting to clock down, when 93*C, it will clock to 400 and 200 MHz(Minimum CPU clock)
For me, it never go over 90*C.
In original i had max. 80*C, this allow +10*C. No.t too much, but i dont want burn my CPU, but if you want, you can set it to more than 90*C, it is your phone ...
GPU temperature is 80*C max. , when 82*C, it will drop to 200 MHz clock,
Original was max. 75*C.( I dont want experiment.. )
CPU temperature range -> CPU clock:
Lower than 90*C -> 1453 MHz
90 - 90,5*C -> 200 MHz (6 Cores)
91 - 91,5*C -> 1133 MHz
92 - 92,5*C -> 800 MHz
93 - 93,5*C -> 533 MHz
94 - 95*C -> 400 MHz
Core shutdowning changed only in 1.st stage, other are original
GPU temperature range -> GPU clock:
Lower than 80*C -> 550 MHz
80 - 81*C -> 400 MHz
81,5 - 82*C -> 220 MHz
---
---
3) Minimum overheating (STABLE)
In short: Lower overheating, but still good performace
This you select if you dont like phone to be hot.
Phone can't go over 70/71*C, that is 10*C under default.The phone is warm, but not hot, it only heating (for me).Here is another system than high performance, when goes "hot" (65*C), system set CPU clock to lowest what can, and every one stage it shuts one CPU core (in last is turned on only one). Dont panic, CPU stay long time middle 65-68*C.
CPU temperature -> CPU clock:
Lower than 65*C -> 1459 MHz (8 Cores)
65 - 67*C -> 200 MHz (8 Cores)
68 - 70*C -> 200 MHz (6 Cores)
71 - 73*C -> 200 MHz (4 Cores)
74 - 77*C -> 200 MHz (2 Cores)
80 - 81*C -> 200 MHz (1 Core)
GPU temperature -> GPU clock:
Lower than 55*C -> 550 MHz
55 - 60*C -> 400 MHz
60 - 62*C -> 220 MHz

4) No aggresive (DANGEROUS!!!)
In short: Minimum limiting CPU temp.. Phone hot but fast. But dangerous !!!!!!!!!!!
I set limit to 120*C, but i mean its have in build protection for prevent damage and its lowering temperature in 100-110*C. But i warning you is dangerous !!!!!!. When goes too hot, phone will automatically fast shutdown ! (Fast shutdown = Same if you use power button in microsd slot)
CPU temperature -> CPU clock:
Lower than 100-110*C -> 1459 MHz
Higher than 100-110*C -> Auto by system default
110 - 115 *C -> 220 MHz (1 Core)
Higher than 115-120*C -> Shutdown device
GPU temperature -> GPU clock:
Lower than 89*C -> 550 MHz
Higher than 90*C -> 220 MHz
No Aggresive 2.0 (STABLE)
In short: If you need maximum perfomance, you will have ! But if you dont want, you will cold.
Fixing this problems with first No Aggresive:
1) Warm-Hot in normal situations:
Not warm-hot phone in normal situations now - when browsing web, switching between apps, messenger, facebook, and other. Phone was heated, not much.
2) Some lag when really overheated:
Faster cool down when in high temp, and more little lag.
You get performace when you really need ! You wont be on low clock when playing games - when you need maximum perfomance, you will have it.
CPU temperature -> CPU clock:
to 45*C -> 1459MHz (Big) 1113MHz (Little)
45-60*C -> 400MHz (Big) 249MHz (Little)
60-104*C -> 1459MHz (Big) 1113MHz (Little)
104*C -> 200MHz (All)
115-120*C -> Shutdown device; Not really reachable. Never reached more than 105*C
GPU temperature -> GPU clock:
Lower than 90*C -> 550 MHz
Higher than 90*C -> 220 MHz
---

5) Very aggresive (UNSTABLE!!!)
In short: Really minimum overheating what phone can, but low performance and unstable.
CPU wont go over 55*C in maximum load, that is good and phone is little warm.Totally inappropriate for hard gaming, but for normal use is good.
Tested with interactive CPU goovernor !
Highly recommened do not use performance goovernor !
In phone startup few minutes phone bit lagging, but after few minutes it will ok.In long time maximum cpu frequency and load phone can lag and cause restart.
If you are using phone for basic things, like Chrome, FB, Office, Phone, etc. Its good. But for hard use try another one mod. Minimum Overheating is better and more stable.
CPU temperature -> CPU clock:
Lower than 50*C -> 1459 MHz
Higher than 50*C -> 200 MHz (1 Core)
GPU temperature -> GPU clock:
(As default Sony settings)
Lower than 55*C -> 550 MHz
55 - 60*C -> 400 MHz
60 - 62*C -> 220 MHz
----
----
6) 26.1.A.2.167_Custom (STABLE)
In short: Modifed default sony settings, more effective with minimum lagging !
Used same system as in Minimum Overheating, when reach "limit", turn on all cores (except 1) and clock to 200 MHz. It very fast cool down !
CPU temperature range -> CPU clock:
60 - 70*C -> 1459 MHz
72 - 77*C -> 1459 MHz
76 - 79*C -> 1459 MHz
80 - 81*C -> 200 MHz (1 Core)
81 - 95*C -> 200 MHz (1 Core)
GPU temperature range -> GPU clock:
Lower than 65*C -> 550 MHz
Higher than 65*C -> 220 MHz

---- Using in real life
Mods are tested with max cpu load, wich my finish is know what is highest temperature of phone with using mod. But for testing in real life need loger time for test.
No Aggresive:
I am using a week No Aggresive mod wich mean phone doing maximum what can, but with more, and really more overheating. But phone alive. Camera app never shutdown! Phone is full time in max frequency (performance goovernor), but in using you feel phone is bit more warm, when playing is hot. Phone never shutdown beacause overheating. If you are like good performace, its good to try this. But dont let phone to be (very) long time in maximum load, max cpu load with camera app and flashlight, its dead combination.(If you do it, then phone go over 100*C,and phone is too hot to touch, but who it doing normally in real use?)
I personally this mod like most, i bought phone with good performace and i knew its is overheating, and dont mind its hot.
Very aggresive:
All important things are in mod title. Its only for basic using, and high cpu load, mean phone will freeze and restart (yes, it did me). If you play with it, good luck with low fps and next freeze. Basic using mean Using Chrome, Phone, SMS, FB. Im not saying dont play videos and dont use camera, it can /and cant lag too, i cant warrant you it, i used camera and YT a lot and all was ok.
26.1.A.2.167_Original
No comment.. This you have if you not modifed it..
Minimum Overheating
I like it. And if you dont like hot phone, but still want play games and use phone a lot, try this. But all is time. In No Aggresive phone never slow down, but temperature is normal 50 - 90*C, when i writing this, phone was 50-55*C. And here we have limit 65-67*C. Its good for gaming not perfect. The clock down from 1.4GHz to 200MHz if you reach 67*C it do for low than one second, and in second is back on maximum. But long time playing it will do more and more frequently.
Minimum Overheating or VeryAggresive? MinimumOverheating better. It is stable and never freeze phone, or lag when using Higher load. (As i say, temperature is 50-90*C in No Aggresive, and Very Aggresive have limit in 50*C.)But phone is warm. Not hot, not too hot to touch, but warm.
Performance Friendly
It lowering cpu clock in 90*C, what in No Aggresive is 50 - 90 is average. As in name, this give you more performance but too more temperature. For gaming, hard and normal use is good. But why i prefer No Aggresive? Beacause when goes to 90*C, phone clock down, and for little time slow down, as in Minimum Overheating. But in No Aggresive is risk to damage device (but i really dont know what this phone can withstand, and i dont want try it), where in Performance Friendly no..
This mod is best for gaming, more better than No Aggresive..
26.1.A.2.167_Custom
To test
No Aggresive 2.0
Really like and using this mod. Prefering before NoAggresive beacause better control When reach high temperatures and gain performance only When you need. Phone stay cold long time (OK, not cold ,but not warm, normal temperature..) and When i start play WoT or RR3 , in first seconds can lag (bit), but its good after that. Phone heat up very much, but can play unlimited time (until battery need charge), but phone will hot.I must inform you i tested it on AOSGP 1.1 ,not in stock ROM (as others). But i think it wont make a sense

does your m4 aqua heat more than 70 celcius?
I thought maximum was 60 -65 celcius.
amazing.
anyway nice fix.
thanks alot.

---

I dont like laggy Asphalt or GTAs, im setting performance goovernor before playing, and it become hot in minutes..

---

Thank you! I will test it. For now i have only a problem: my phone randomly reboot. I not think its because of battery removed and reinserted, all connectors are ok! I will try minimum overheating and then maximum performances...

---

Random reboots
I had too random reboots and app crash, i had firmware. 128 Commerical and Journalists, now updated to. 167 and all ok.Good is do LogCat if you have Root and read.. Or send to developers what know it..

---

hi..! i like your tweak and I appreciate your work. but, I have a small question and am in need of some help. could you please explain me what the numbers mean? i could understand the file partially but to do tweaking by myself... I can't understand exactly how to command a core shutdown.
I am really interested to modify the cpu core behaviour to the temps. i bought this phone indeed to do this and use it without overheating (thanks to you). if you could kindly help, I will do the tweaking according to my likings and will post them to you.
could you kindly do that? please?
thanks in advance

I did what i can
1) Example:
[TUL_8936_NORMAL_BIG_CORE0]
algo_type monitor
sensor tsens_tz_sensor5
sampling 1000
thresholds 50000 60000 70000 90000 100000
thresholds_clr 40000 55000 60000 80000 90000
actions cluster0 cluster0 cluster0 cluster0 cluster0
action_info 1113600 800000 800000 533333 400000
2)What is what:
[TUL_8936_NORMAL_BIG_CORE0]
-- its like title..
algo_type monitor
-- do not modify it..
sensor tsens_tz_sensor5
-- senzor name
-- you can check senzor names in Aida64 or other apps
-- you can change it
-- when temperature in this senzor will reach thresold, or go over, action will trigger
sampling 1000
-- dont modify..
thresholds 50000 60000 70000 90000 100000
-- my favourite thresolds,(=limits)
-- limits are separated with space (50000 60000)
-- limits are in Celsius units (°C)
-- limits are in 1*1000 units, that mean 1°C = 1000. Example: 50000 is 50°C
-- when is this reached, action will started/did
thresholds_clr 40000 55000 60000 80000 90000
-- same as up
-- it is start of limit
actions cluster0 cluster0 cluster0 cluster0 cluster0
-- name of the action (what phone will do)
-- you can change it, names of actions are down
-- actions is knotted to action_info
-- if actions are more than 1, they are separated with + (Ex. Cluster0+Hotplug0+Hotplug1)
--: cluster0, cluster1
-- it will change cpu clock to every 4 cores
-- cluster0 is for .BIG cores , cluster1 for .LITTLE
--: hotplug0 , hotplug1 , hotplug2 , hotplug3 , etc.
-- it will turn on or off core (number at end mean number of core - ex. hotplug0 manage core0)
--: gpu
-- it will change gpu clock
--: s_cam, battery
-- i dont know , sorry
action_info 1113600 800000 800000 533333 400000
-- details of action
-- if actions are more than 1, you can separate it with + (Ex. 1113600+0)
-- here is CPU clock , in Hz (400000 = 400 000Hz = 400MHz)
--: if action is cluster0
-- then here you write CPU clock in Hz (as written up
--: if action is hotplug0, hotplug1, etc.
-- then here you write number 0 or 1.
-- 0 mean CPU Core will Turned On
-- 1 mean CPU Core will Turned Off
--: if action is gpu
-- then here you write GPU clock in Hz

Hello:
I used the "PowerSaving" method mentioned in this post, also I tryed whit ROM Toolbox Pro, to force the CPU stay in 200 MHz all the time.
But it stills overheat like hell: 70ºC when screen is on and 45ºC when screen is off.
Can anyone help, please?
Thanks in adivice

Personally, the first firmware OTA update i had for my 2306 fixed overheating. But why not try Coolify? Seems safer

Question: does this work on 26.1.A.3.111?
Coding is the same as 26.1.A.2.167, just change a few values on 26.1.A.3.111. Default 26.1.A.3.111 seems to have better overheat handling than 26.1.A.2.167.
Gonna backup originals and use MinimumOverheating, see how it goes.

Does this work with the latest android ?

I change the governor to performance and it does not decrease the frequencies until I reach the temperature that establishes the configuration in this case (performancefriendly)
