[HOWTO] Save Battery with better CPU Handling [2016/03/07] - Redmi Note 2 General

What is this?
This is an app, written by me that configures the CPU governor and some other things to save a lot of battery, while have the system as fluid as possible. (Less lag and better battery than factory settings)
I also made some configurations available for the user.
How to get it?
You can install the app from Play Store - Redmi Note 2 Tool
Start it, and give it root permissions. Without root permissions the app will refuse to do anything!
You can use the values given by me, or change them. Either way you need to tick "Set On Boot" in the menu, and press "Save&Apply".
You need to enable Autostart for the app in MIUI security center.
Battery stats are in the next post.

Latest standard version.
11.5H without charging, WI-FI always connected, 6H screen-on, 1.5H gaming, the rest is FB, 9GAG, Messenger and browsing.

I have to say that the Android battery stats are also very inaccurate, the most battery was used by Jurassic World and Angry Birds (each about 15-25%).
Also remember, this is the standard version, No Touchboost has even bettery battery life!

Nice! and what is this touch boost anyway, is it gonna affect performance or something?

great tutorialyeah..what is touchboost?is it thst important or no?

Bookmark firstly ,anyone used this skill ? Does work well ?

great,just great!
thx! i will use 1469 here.

Thanks. Can we limit core number with this script ?

How can I set TouchBoost Frequency and number of cores?

i guess kernel editor from the playstore can do stuff likes that and works well on helio x10 devices.

How can I check if I done it well ?

antutu result should be lower than before,cpu z show frequencies too.

Do you notice any lagging problem from doing this?

At 1.2 ghz I got sometime some fps drop in task switch and during unlocking. But it is generally during 1 sec or 2. Antutu dropped to 33000.

i cant make it work.

this solution is not working with me

As you may know, I have a thread about a modified ramdisk kernel to save battery, but I don't want to release 3+ versions with a new kernel every week, so here is a solution which doesn't require flashing, and can survive OTA updates, etc.

SetCpu

Right,
Now were rooted ive installed this but how do you use it correctly to save battery? theres some way to slow processor when your phone is asleep or something? I carnt seem to find it!
Just tap the widget on the screen, or install widget on screen, then tap it

There's profiles button in the app. You click it, then you enable selected profile and set your CPU speed for it.
The only one I use us to underclock the phone when it's on standby. Can't really tell if it helps as today is the first day I'm using it.

I installed SetCPU after I put the MCR on and it's made a shocking difference to my battery life. I did find using the active widget seemed to slow things down though.
[EDIT] To clarify, literally doubled my battery life.

Placebo effect...
I installed SetCPU and from a full charge my phone died in 3 hours lol. Uninstalled and now lasts a good 24 hours.
does not work untill we have full system write access priv
jd
For now, SetCPU will have no effect when running on rooted Desires.
When you pull the sliders across, it seems to have no effect, and the green max and min frequencies remain unchanged. HTC has a driver that they implement which keeps overriding SetCPU. We need to hope they (HTC) release the Kernel source. Once this happens, there will surely be a release of a modified Kernel with SetCPU support and overclocking/undervolting.
Problem is HTC is really slow in releasing the GPL'ed Kernal source, it's borderline, illegal, and very irritating

are they still doing this as setcpu seems ok for me
For use it..you must have a kernel with patched init.rc to load modules on start
and you have to install permanent perflock disable and cpu govenor (interactive and powersave)
and mybe the new sense undervolt

About Team-Nocturnals Shooter (Full sense 3.0) for Speedy

Great ROM, stable, no lag. But I have noticed some bugs or weird features in Team-Nocturnals Shooter, GB 2.3.4 Sense 3.0 dodge kernel 1.6, HTC Evo Shift 4g
1. It's near to imposible to add HTC widgets to the home screens because when the desired widget is selected, the system returns to the customize home screen section, so the widget isn't added or very rare.
2. When managing apps, if you go to the app details, sometimes it will start to compute the size of the app changing numbers very fast; If you click on the Move to SD card when the numbers are changing, you will move another app (not selected) or get error messages.
3. The Quick settings area at notification area show as second line 'Javascript' or 'Navigate away from this page?' in most options.
Question: Is it posible to use wide backgrounds and move between home screens moving the background to? I don't see how.
this should be posted on the roms post
Yes I know, but I don't have enough "useful posts" to post there.
Well we'll just see what we can do about that

hehehe Ok, I will do it, this is a very nice ROM and I want to help to find any issue as user.
Thanks
Ok, tnx a lot. I'll do it.
In the meanwhile, I noticed that the apps moved to a SD card and added to any home screen, will lose their stock icon in the next boot, showing the generic android app icon. That's another issue with this rom.
This is a probably more a question than a incident. I use an app to protect apps from running without a pin or password to protect privacy. Smart applock Pro. I used the stock rom, cm7 based, sense based, and this is the only rom where I'm getting a message from the market telling that the app is not suitable for my device.
The free version doesn't show that message, and was installed without any trouble. Developer or ROM issue? I will check.

i have the same issue here. this works in mikg. but not in shooter... i've done a full wipe too.... any ideas?
Suddenly with this rom my cel become more and more unstable, I got frequent reboots, some lags and error messages. And even I never had the video playing issue (I read somewhere people with an issue when playing video) it finally appear . Plus now, when a I get a call, the caller id image is like garbage video. I liked this rom at first because is fast and has the best sense I've seen since the stock rom. But I'm not using it anymore, I changed briefly to MikRunny beta (sense 3.5), it's a little heavier than this, but better I think. I returned to a cm7 based rom because MikRunny is at beta stage and I noticed the enable/disable 3g control is broken and I can't switch between networks easy, just rebooting.
May be the celphone became unstable because I was trying different values for the cpu clock and governor. I was using dodge kernel and played with smartass, ondemand and interactive governor settings, and with bfq and deadline schedulers. My best experience was with deadline and ondemand scheduler. It was as if I had a new and faster phone.

[Q] Any good *working* CPU profile apps like Set CPU?

I'm on lollipop so I just noticed but SetCPU hasn't been working for a while.
I need a program where I can say
When screen goes off -> underclock to X, importance 5
When battery at 50% underclock to Y, importance 1
When battery at 35% underclock to Z, importance 2
etc.
I only want it for underclocking. The build in battery control doesn't do much and my battery life is pretty terrible when I use the phone (screen on) a lot. I've tried CPU control pro and it would only allow me to set single profile, not have it changing interactively. If anyone has any good apps they've been using let me know, I need to do something about this.
Thanks!

Since over/underclocking requires root the answer is there is no such thing for lollipop

I am rooted, on JasmineROM 5.1 (LP 5.0). I just followed the instructions avoiding the OTA and retained root. The CPU control programs I've found work for one setting, just not with profiles.
Let me widen the question out. Does anyone have any good CPU control utilities for LP or KK?
I know there is no going back one you're unrooted on LP although I've heard if you go back to 4.4.4 there is a method.

Battery Care issues

I've been using XC for a month now. Battery Care worked only during the first few weeks and now it refuses to work anymore. For the past few days, I've been trying to figure out the cause. I even decompiled the APK and am studying the program logic. But I need some live data from working device to help me better understand. If your phone is rooted and Battery Care is working properly, please send me the following files to check. Hopefully the result will help to fix our problem regarding Battery Care. Thanks!

Your phone unlocked or rooted? If so, please try BatteryCare+. My problem is solved after running it for a week to learn my charging pattern correctly. And now Smart Charging has been activated again and running for the past few days already.
Yes, BL unlocked and root. I'm gonna try. Thanx a lot!

Even if you don't have Xposed installed, the app can still show many useful information which may help you troubleshoot BatteryCare problem.
I got xposed, i am still on Android 6. It looks like this :

You can try it for a few days and will see the Predicted time should match closely with the Actual time which will result in successful prediction. If all goes well, BatteryCare should resume again. Please be reminded to set the alarm clock BEFORE plugging in.
BTW, you should see values in Score and Less than 1 week after the first charging event. But currently the value for Score is not very accurate. I'm working on it now.
I set alarm clock daily at 5.45, except Saturday and Sunday.

Add app to game optimizer

Hello, recently just updated my v20 to oreo and it got game optimizer which I've been eagerly waiting for. Unfortunately it won't detect my game as it should've as it is an unofficial app name (i used apk editor and change the package name in order to have 2 id on 1 device)
Is there any way to add this onto the list manually? My phone is currently not rooted, but if root can solve this issue, I will happily go through with it since my warranty is already expired.
if anyone know how to get it detected through editing manifest file is also appreciated, thanks in advance

Thats just a gimmick, its a useless feature, i have a couple of games on it and i can change graphics, take a screenshot and the break time which is the only thing useful
You can use SQLite Editor to add custom apps into com.lge.gametuner.

It is not a gimmick and can be useful for some games that renders the game at native screen resolution which the graphics settings can forcefully set to 720p or 1080p.

That's the reason I need that feature lol
My game always render app at my native resolution and it lags after 10 minutes or so gameplay due to the heat it generates
Some of my games are smoother ever since I set them to 720p, that's why I need it to be able to add other application as well, especially some games/apps that I sideload since all of them are not detected
