[Q&A] CPU Bug 100% usage

2019-05-21 16:13:08

Hello! I have a problem with the processor frequency, it's always at 100% usage. That's why the phone goes slowly, for example, it takes about 20 seconds to open the "Options" application.
I did factory reset but failed.
Even my old phone with an SD801 goes better.

Thank you for your attention

what is the vendor/model of the fingerprint sensor in your unit?

right, fingerprint can't be the cause of your high cpu usage. some combinations of xiaomi phones and versions of MIUI have had a high cpu usage issue with the other vendor of the fingerprint sensor. i think "fpc" is the "good" one.

so i guess you should try to determine which process(es)/app(s) is/are hogging the cpu...?

Hello,

Did you try to flash ROM via fastboot?

Which ROM are you using now?

Hello! I do not think they are the apps problem because when I did the factory reset I had the same problem, even if I deactivate the fingerprint sensor I have the same problem.

With the 100% CPU Usage, it's a known Thing ! A Lot of Users Had reported it already, but no One Had any negative Effects because of it ! Also I read somewhere that with Android 8 or 8.1 there is a Security Feature that doesn't allow Third Party Apps to enter the Cores, so the shown results are probably wrong ! I wouldn't pay it so much Attention...

just a side note the CPU temp is kind of low for 100% of CPU core demand imo

Hello! I should care because the phone runs
very slowly, for example when I open "Google Chrome" it takes about 3 minutes to open.
