[GUIDE] MIUI Battery & Multi-tasking Fix v4.1 (Updated) - Xiaomi Redmi Note 3 Guides, News, & Discussion

Redmi Note 3 (SD / MTK) Battery & Multi-Tasking Fix v4.1
For MIUI7 & MIUI8
Mediatek & Snapdragon Variants
Global/China & Beta/Stable ROMs​
MIUI is a forked version of Android with plenty of additional features & tweaks not found in stock AOSP ROM. MIUI is very smooth & has a great battery life on the Redmi Note 3. The powerful Snapdragon 650 with its excellent single core performance coupled with dual channel LPDDR3 RAM & eMMC 5.1 flash storage results in blazing fast 1st time app opening speeds.
MIUI by default is very aggressive at killing background apps in the running in the memory, as a result it is unable to keep more than 3-4 apps in the memory while multi-tasking or after waking up the device. Default settings are aimed to keep as much free RAM as possible thats where the problem lies. It kills the apps running in the background to keep most of its RAM free. Apps get killed & have to be reloaded again from the flash storage into the memory, this takes a lot of CPU, I/O cycles & makes the end user experience less enjoyable. Below settings might make your multitasking a bit better at the cost of less free RAM, but that shouldn't matter as RAM is meant to be used not kept free. Always remember "Free RAM is Wasted RAM.

Wiki : What does each and every option do?
• Memory Optimization : This option sets the swap file for multi-tasking. Size varies according to the device and RAM configuration.
- High: 767MB to 1GB
- Middle: 767MB to 1GB
- Low: Swap file disabled
- Off: Swap file disabled
• Show All ANRs : This option enables MIUI to show an obtrusive dialogue box after an app fails to stop responding . Setting this off doesnt show the pop-up frequently.
• Force-Closed Apps : This option enables MIUI to show an obtrusive dialogue box after an app force-closes unexpectedly. Setting this off doesnt show the message. It enables after every reboot.
• Turn On MIUI Optimization : This option enables a plethora of MIUI based settings & optimizations as per the guidelines set by the MIUI developers. It helps to load the app and the app data in parallel reducing load times and ensuring snappier user experience. This setting can sometimes cause a variety of issues on non-MIUI based apps such as Google Apps & Apps from Google Playstore. Its better to disable if you rely on Google Playstore for apps & services or use Global Stable or Global Beta MIUI ROMs
With the MIUI Optimization Enabled, some users reported the following issues
- Cannot set third-party launcher like Nova, Apex or Google Now launcher.
- Wallpaper cannot be set using in-built options via custom launchers.
- Occasional lags, stutters or freezes while scrolling web-pages & long lists.
- Custom apps set as default restore to default MIUI apps on reboot. (Only on MIUI China ROMs)
- Cannot set accessibility services on reboot.
- Background apps cannot sync data.
- Music players stop playing after sometime.
- UI Animations are not synced properly.
• After turning off MIUI optimization
- Above issues may get solved.
- Settings > Data Usage > Graph changes to AOSP style.
- Settings > Battery & Performance > Battery Use > Graph changes to AOSP style.
- Settings > Installed Apps > All > Documents > It will not be disabled after every reboot.
- Settings > Additional Settings > Buttons > Settings may get reset.
- No OTA update notifications. Enable it to receive the OTA updates.

I would love to know what this option does.
I disabled and i notice that the device is a little smoother. I have one very big folder with all the useless apps, scrolling was always stuttering in there.
Now its smooth.
EDIT
My device is the simple redmi 3, but i still would like to know what is this MIUI optimization.

Settings App > Additional Settings > Developer Options > Memory Optimization : Enabled
only got off,low,middle,high. no enabled. so which one better?

It sychronizes the UI thread with the animation time, so by keeping it disabled the clock timer doesnt have to wait for the animation to start/stop. The CPU effortlessly renders the animations without waiting for the MIUI framework to sychronize the animations.

that was a mistake, I edited it. Keep it DISABLED

Still doesn't work for me. It keeps closing my apps,sometimes even when i'm still using them. It closes my apps even when I lock them by swiping down.The ram management is just too aggressive.

Thanks man you fixed it :good:
Much smoother and useful

same to my with spotify
Hi there.... I have this problem when I play music with SPOTIFY in background. (redmi note 3 pro 16GB - global stable MIUI 7.3.2)
The music stop playing. I can see the app get killed by MIUI. This happen even if the app is locked and is in background. This problem doesn't happen with google play music. When I turn on the screen I can see that is not image and song name just like this
when I turn on the screen this is like this imgur image [o9nTtWD]
Already tried all this recommendation without success.
thanks
EDITED: Now with last correction spotify runs OK, Thanks

This will prevent the SystemUI from showing XYZ app has been force closed for an uninterrupted user experience.

Donwload kernel auditor, go to "Low memory Killer" set to Medium or Aggressive if you have lag (you shouldn't), now the phone can keep around 10 apps in memory.

Thanks. It helped. Was frustrated by apps getting closed

This was the last correction
"Settings App > Additional Settings > Developer Options > Memory Optimization disabled"
Because the original post said another different thing. Also remember keep spotify lock on memory
Open spotify -> press home button -> press menu button -> pull spotify DOWN

I have followed all the steps, and some tips I found on other links (enable apps to autostart), but my apps still get killed randomly. Any more advice?

Slow graphics/transitions on a Note.

I picked up a Note a couple of days ago, and I've noticed that graphical transitions are slow, almost jerky.
Good examples are when launching the multitasking interface, opening folders in Apex Launcher (everything is the same with the stock launcher, too) and turning the screen off. When turning the screen off, it fades out slowly and in stages rather than smoothly. This may be normal, but if not it's a good example of how bad the animations are.
The phone came wiped, but is there anything I can clear that may have been missed by the original owner and needs clearing down?
Or is this just normal?
Cheers.
go to settings > developer options and select force GPU Rendering, Also go to (in the same menu) Window / Transition animation scale and set them to 0.5 - 1.0 on both.
Wich android version do you have?

Thanks. Doesn't seem any different, though.
I should have mentioned, I'm updated to ICS - 4.0.4.
Thanks.

App detecting: Fake apps can be detected to prevent potential risks.
Privacy security: enhanced permission management for privacy protection.

List of hidden S6 activities

You need to have Galaxy S6 or Galaxy S7 with Nova Launcher and Marshmallow.
Confirmed working on SM-G925F
So, to access hidden activities you need to add Nova Launcher widget called "Activites" then scroll down to "Settings" and select something from list. Some things won't work (they are not available, need additional permissions etc.), some of them are already available via Settings. I am not responsible if tinkering with activities do something nasty to your device!
However, there are some options that are hidden but can be very, very useful.
Hint - you can "test" specific activity by long press, there's no need to put every activity on home screen and test it that way. Also, applying settings isn't dependent on Nova Launcher, ergo you can use whatever you want after changing something.
Here's what I've found:
Settings
.DisplayScalingActivity - enables condensed view of system UI, same as on S6 Edge + or Note 5, meaning smaller icons and UI elements.
.IconBackgrounds - enables homescreen and app drawer icons background like it was in Marshmallow Beta.
.ModePreviewTablet - enables additional "Reading mode" in display options. It dims screen so I don't recommend using it on bright daylight because it can be harder to see assets on screen.
.networkconnect.NetworkManagerActivity - holy **** this one is nice. Allows you to select which app can use WiFi and mobile data. Also it allows you to select which apps can use data even after data usage warning is shown.
.RunningServices - shows running services, like in Developers Menu
.Settings$AirCmdSettingsActivity - S-Pen Air Command setting. It won't work since S6/S7 doesn't support S-Pen functionality.
.Settings$MemorySettingsActivity - Shows RAM usage options like on stock Marshmallow, at least I think. Very helpful for troubleshooting misbehaving apps or battery consumption.
.Settings$ZenModeSettingsActivity - it seems like this is Do Not Disturbed (DND) on steroids. You can add additional rules and select which events can have priority.
.UsageStatsActivity - shows usage for every app on phone. It lists app name, Last time app was used and for how long.
.wifi.WifiConfigInfo - very detailed info about configured WiFi networks.
System UI
.settings.BrightnessDialog - shows small slider for brightness
.DessertCase - old KitKat hidden animation from About
.egg.MLandActivity - hidden MM game
List will be updated with new discoveries.
Link for the widget please?
I am not able to locate it will Google search.
it´s a widget of nova launcher...just add the widget to homescreen

Battery manager stuff ?

Hello everyone !
I just bought a Redmi Note 7. This morning my alarm didn't ring for some reason. I use the Google Clock. Also I can't make "OK Google" working when my screen is off. Some notifications take time to be showed. Etc.
Is the battery manager thing responsible of all those "bugs" ? Is that a weird "Greenify" ?
Since I didn't unlock the device and install a real Android ROM, any of you have a solution for alarm so my boss don't kill me tomorrow ?
Thanks for your help guys.
Settings > manage apps > clock (or any other app) > battery saver > no restrictions.
Also enable autostart in the same settings menue.
And avoid stuff like naptime, if you are not experienced with such things.
Hi there. It's probably a MIUI battery saver thing. So for all of your mission critical apps whose notifications you want to receive instantly, do this:
1) Go to app settings for the app in question
2) Toggle on Auto start
3) Turn on all notifications that you want to receive
4) Set the battery saving setting to no restrictions.
If you notice that an app still gets closed in the background for some reason, add another step:
5) Open the app and then open the Recent apps screen. Tap and hold the preview image of the app in question. Tap the first icon (lock app). This will lock it in memory and only you will be able to manually swipe it off and clear it from memory. Tapping the Close All button in Recents will not close the locked apps.
After I had done this with the apps that I wanted real time notifications from (or battery tracking apps that I wanted always running in the background), I've never had any issues with late or missed notifications.
I don't use 'OK Google' to wake the phone. I'm not sure if this is possible with all newer phones or only with specific SoCs.
Thanks for your answers. That was that battery saver options. Have a nice weekend.
