Description
Somehow, the processor locks on maximum frequency, all 8 cores stay on maximum until I reboot the device. I've tried to see if it's an app, but it's pretty hard to see. The same problem may be related to excessive battery consumption, either in use or in standby mode.

-- UPDATE --

Apparently, devices with the Goodix fingerprint sensor, when is activated to unlock the screen, has the processor locked on maximum frequency.

Feedback app ID:

501319398
Steps to reproduce
Enable the use of a fingerprint, the processor will lock on maximum frequency.

Basically this a useless discussion and a waste of time.
Xiaomi will fix it IF and WHEN they want... at moment they are more worried putting ads on their smartphones rather then fixing (or atleast akownledge) impacting bugs.

Details of this issue:Requeriments:
  • Have a Goodix fingerprint sensor (You can use phone *#*#6484#*#* to see what sensor you have)
  • Use fingerprint to unlock smartform (If you turn on screen with power button and then use FP to unlock, issue not occurs; but if you with black screen use FP to turn on screen and unlock, then issue ocurrs). Obviously, if you don't use FP, you haven't issue.

Consequences:
  • Modify value of files: /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq, ...., /sys/devices/system/cpu/cpu7/cpufreq/scaling_min_freq
  • In theses files, the value is put to max
  • Then frequency of all cpus run at max
  • Then battery drain


Xiaomi, need you more details?

So since two september updates didnt solve this, before I throw the phone out in the garbage where it belongs in it's actual state, can a xiaomi employee (not a hardcore fanboi) comment their position on this bug?

Update!

Apparently Xiaomi is testing the solution together with the Beta team. A user here in Brazil receives the updates and according to him, the Kernel was changed in update 9.6.13, for some solved, but there are users who still report the same problem.

I hope the October patch brings some good news.

Hi guys everyone who has this bug needs to send a feedback along with bugs log from Feedback app.With a screenshot.Also the title needs to be "Processor stuck at maximum frequency" There's NO NEED TO REPORT SAME BUG TWICE.The reason is because the DEVELOPERS TEAM NEEDS MORE INFO (BUG REPORTS)

Mine 4/64 A2 is also stuck in the maximum frequencies, if i reboot the A2 the 8 cores go up and down normal, but after some time of use, it returns to jam in the maximum values.

Should i return A2, is it a hardware or software problem?

I have had my phone for 3 days now and battery life is awful because of this... I am considering returning it back. It is the first Xiaomi phone I've owned. How good/bad are they with solving bugs like these?
