Since the latest updates pubg started laging in my poco. I ran geekbench and the scores were really low for a sd845 device.
It was like this in Geekbench 4.4.1

The ideal score of an sd845 device in geekbench 4 score is like around 2400 in single core and around 8000 in multi and in geekbench 5 it should be like around 500 in single and around 2000 in multi. So the scores i got were too low for a sd 845 device. Its even lower than old 835 or 820.
Then i tried to find the reason and saw many posts and videos regarding the heavy thermal throttling happening in poco.
Here are some results from thermal throttling testing app.

So poco starts throttling as soon as we start the testing app. Here is a throttling test result from a comparo video between poco f1, realme 2 pro and one plu 6. We can clearly see the Poco throttling heavily whille other 2 phones are barely throttling.

We ran these benchmarks and throttling tests in my and a friends poco and both were getting same reults. In some posts in xda and mi community, some guys saying that throttling happens because of design flaws or hardware issues in poco. Due to that it cannot dissipate heat hense throttling.
So to find out whether it is hardware issue or software issue we planned to flash old good miui 10 based on oreo because problems started since the pie based miui10 introduced.
So we flashed Miui 10.0.6.0 based on Oreo on friend's poco and here are the results.

And here are some throttling testing results.

So, as you can see both geekbench and throttling tests bcame positive. In geekbenchs it scored respectable results for a SD845 device.
In throttling we can see that there is not much throttling happening and cpu runs at higher speeds hense higher scores but at the same time it runs cooler too.
So it seems that they ruined the miui in poco in the latest miui builds. Cpu profiles seems messed up. In oreo build cpu runs at 68 degree while its working in its 90% speed whereas in latest builds it runs at over 78 degrees when working around 60% or less speeds. In oreo cores are running at 2.5 ghz speed but temps are about 40 degree but in latest builds cores are running at 1.7 or lower ghz but temps are over 55 degree.
So the reason behind heavy throttling is cpu runs hotter than usual. It stars heating as soon as if we starts any resource hungry apps hence throttling happening and cpu runs in half speeds and low benchmarks, performance and laging issues in apps games etc. In oreo build it was running cooler and not much throttling needed and there were true SD845 performance on tap with higher efficiency too.
So my question is, when will this gona sorted out? Lets hope they wont ruin the upcoming miui 11 like this .
Note: For those guys who are going to tell that benchmarks are just numbers, real performance matters, your phone is hot while testing, your country is hotter, blah blah...
I am not talking that we want more benchmarks score or we need 855 like scores etc. Half the scores than others devices with same chipset is not acceptable. It indicates that something is wrong there..we want to fix this issue asap..
