[Xiaomi Poco X3 Pro] Alezo:
⚠️

THIS

WARNING

ONCE

!

- CALIBRATION OF THE IC, WOULD NEITHER RESULT IN A HARD BRICK/PREVENT BRICK. AS TO BE CLEAR WITH THIS *HOW TO THREAD*, IS ONLY MENT FOR PEOPLE HAVING PARTIALLY BUGGY PMIC, FACING AFOREMENTIONED ISSUES, HAVING NOT SO GREAT BB LIFE, etc etc. IF YOUR UNIT HAS A RIGGED IC (mind you) nothing can save you from the catastrophe, rather than the guys at SC.

Just to be clear calibrating your IC is completely a safe thing to do, unless you're *someone that finds hard time reading the entire THREAD and jump right into the process* as said such comments will be ignored.

-------------------------------------------------------------------------

Apparently there have been numerous cases of poco x3 pro (indian variant -Bhima) bricking itself out of nowhere, while charging, while being idle or in some rare occasions while playing heavy games like BGMI/PUBG, CODM, GENSHIN, etc etc.

Usually when the device is on the verge of getting bricked it gives a fair symptoms like (glitchy screen, lags, unresponsiveness, random reboots out of any prior initiated action).

THE PMIC USED IN POCO X3 PRO is -

QUALCOMM™ POWER SOLUTIONS PM-8150L (PMIC) for SM8150-AD (SNAPDRAGON 855+/860 SOC(system-on-chip) )

*SOME MILD SYMPTOMS -

- LAGGING

- HEATING EVEN WHILE DOING BASIC STUFF

- RANDOM REBOOTS.

*SOME SEVERE SYMPTOMS -

- GLITCHY SCREEN (GREY SCREEN, WITH PARRALEL RETRACING LINES)

- FREEZING OFTEN

- TOUCH ISSUES

- PROXIMITY AND LIGHT SENSOR DYING OCASSIONALLY (WITH AN INTERVAL OF 2-3 DAYS or daily after every 2-4 hours)

*HOW WOULD CALIBRATION HELP?

- DISPLAY APPROPRIATE BATTERY % LEFT

- SENSOR DEAD ISSUE IS PERMANENTLY FIXED (UNTIL YOU RESET THE CALIBRATION).

- IN SOME VAYU VARIANTS( WITH HUAXING PANELS, might fix the issue with ESD in the Digitiser panel of the display) check for yourself if it works in Tianma or not.

- SPEAKERS SOUND GREAT.

- THERE IS A VERY LESS CHANCE OF KILLING YOUR BATTERY IF YOU ARE A USER THAT CHARGES THEIR DEVICE AFTER DEVICE HITS 0% (since we all know the device might do dead if it brought down to zero) (as PMIC is buggy).

- Charging decimals start to appear always (might be something most of px3p users want for a long time).

~~~~~~~~~~~~~~~~~~

* ⚠️ WARNING -

- You're doing this at your own risk, on an account of any unpredicted outcome caused due to lack of reading the entire steps, will be ignored.

- Im not responsible for any hard bricks, soft bricks, you are doing this at you sole risk and you will be held responsible for your actions.

* Pre_requisites -

- Stock charger and cable.

- The device itself xD.

- Some patience and a bit of brain.

*Method -

- use you device and let it drain out all the juice and drop down to 1%

- just as the shutdown indicator starts (giving 30 seconds) to plug your device

- Plug it in and charge it all up to 94.50%

- While plugged in force reboot into fastboot mode (volume - (down) + Power key)

- As soon as device boots into fastboot (turn off the charger brick from the outlet) (DO NOT UNPLUG!)

- NOW TURN ON THE CHARGER again and force boot into recovery mode and from there boot to system from recovery options.

- As soon as you boot you will notice different battery percentage, probably 100%.

- USE YOUR DEVICE UNTIL IT HITS 25%

- AS IT HITS 20%, FORCE BOOT AGAIN INTO FASTBOOT AGAIN (THIS TIME WITHOUT USING CHARGER) AND DO THE SAME AGAIN [FROM FASTBOOT TO RECOVERY AND THEN SYSTEM AS MENTIONED ABOVE, BUT WITHOUT USING CHARGER THIS TIME)

- Now you will notice different battery percentage again after reboot.

- Drain down battery to 15% and charge it up to 85% and use the device, as now you have successfully calibrated the PMIC.

⚠️Important⚠️-

After this calibration you are only allowed to fully charge once in two weeks or three to avoid issues.

- My personal recommendations are

(15 - 85%) rule while you're home.

(20-95%) rule while you have to go out for work/institution.

- warning ⚠️ (only tested in stock MIUI, any other roms are not tested, so you can try it for yourself and you have been warned!.)

- Tested Personally on both (VAYU [GLOBAL] and BHIMA[INDIAN] variants)

Vayu - 6GB/128GB (HUAXING) - RJUMIXM [12.5.7.0 STABLE] [13.0.3.0]

Bhima - 8GB/128GB (TIANMA) - RJUINXM [12.5.5.0 STABLE] [13.0.1.0]

* How to check?

- if you previously had issues with sensors, they will be fine and if it doesn't and keeps dying repeat the process again with proper reading of the steps this time.

- ESD issues fixed in TP, (GHOST TOUCH) will be less or maybe fixed permanently. [ Not confirmed]

- Speakers sound louder.

- less heating.

Update :

Gyro Delay is also fixed.

Update Feb 9th.

- Tested on Arrow OS, PE+, MIUI PULSE, MIUI BGST (MINT BGST), GLADIATOR OS, (more to be tested and added)

- All kernels have been used and checked, (thanks to the testers out there for checking/verifying).

Thanks are appreciated.View attachment 5524227
