[Xiaomi Mi Max Guides, News, & Discussion] Davide__97:
Hi, this is my first guide.

In this thread I'll tell you how to root Mi Max (Helium, but I think is the same with Hydrogen), how to optimize battery for consume about 1-2% during the night with WiFi on, and how to fix push notifications.

(

You should have a MicroSd!!

)

In first you must download these files (for helium):

Boot.img (V8.1.3.0.MBDCNDI) - http://mi-globe.com/index.php/mod-download/?mod=pboot&device=helium

Chinese stable ROM - http://en.miui.com/download-302.html#446

SuperSU.zip - https://download.chainfire.eu/897/SuperSU/BETA-SuperSU-v2.67-20160121175247.zip

Recovery TWRP- https://dl.twrp.me/helium/twrp-3.0.2-0-helium.img.html

and these (for hydrogen):

Boot.img (V8.1.3.0.MBCCNDI) - http://mi-globe.com/index.php/mod-download/?mod=pboot&device=hydrogen

Chinese stable ROM - http://en.miui.com/download-302.html#445

SuperSU.zip - https://download.chainfire.eu/897/SuperSU/BETA-SuperSU-v2.67-20160121175247.zip

Recovery TWRP - https://dl.twrp.me/hydrogen/twrp-3.0.2-0-hydrogen.img.html

(I DIDN'T TEST PROCEDURE ON HYDROGEN! BUT SHOULD BE THE SAME!)

For first thing you must flash TWRP. You must have bootloader unlocked, than put your phone into fastboot mode (Hold volume down and power button when you phone is off). While is into fastboot mode, connect your phone to PC. Put your downloaded files on desktop, press maiusc+right side of mouse, click on open comand windowd here, and type "fastboot flash recovery" then do a space after "recovery" and drag TWRP file on comand window, press enter. Now twrp should be flashed on the phone, and on window comand you should see that the process is complete. Now you should put others files, less TWRP on microSD, and put microSD into your phone. Go on recovery (hold volume up+power button, when there is Mi logo, you hold only volume up until it is into recovery).

Go on to install and flash files in this order. ROM, Boot.img and SuperSU, for everyone do "wipe cache/dalvik cache. Files are in sdcard1), then reboot phone. Once is on, through Mi Store, search and download google apps. (search google on search bar of mi store, tap on blue paw saying "du", then tap on install and launch for installing everythig. You will be asked to enable unknow sources).

Now phone is on and rooted and there are also google apps. for fixing push notifications, you must download from google store "/system/app/ mover" (https://play.google.com/store/apps/details?id=de.j4velin.systemappmover&hl=it). Give every permissions to google apps (Go in security app, then permissions, and click on google apps. Do every permission!!! Is important!) than go on system/app mover and covert every google apps to system app, without rebooting the phone! Only after that you moved every app to system app reboot phone (Now push notifications are fixed, but you should disable every battery optimization

for the application from which you want to receive notifications, and if this doesn't work, you can lock app in multitasking dragging app downward, and tapping on padlock). then for every applications that is not important you can disable background activity through battery optimizations.

Xposed (for helium) you should download sdk 23, ARM 64 and flash it by recovery, then install xposed app in your pone.

For less battery consuption, I receive push notifcations always only from whatsapp, and I disable background activities from others dwonload apllications (DON'T TOUCH STOCK APPLICATIONS!).

I consume about 1-2% in one night (About 9 hours).

Sorry for my english, I'm italian.
