[Xiaomi Poco X3 Pro] Georgeknk12:
Hello people I guess maybe I am a little late since Poco is little old smartphone or I may be captain obvious here lol but here it comes.

(Caution long thread is coming written in bad English so hope you make it to the end without a headache) :p

Soooo I watch people having their Poco x3 pros dying and have seen many discussions/videos about why that happens with lots of BS and missinformations that have being debunked.

I won't go into details but some of those reasons don't make any sense to me but I just mention them.

1) bad software update.

2) buggy/bad quality pmic chip.

3) ram soldered on top of CPU.

4) insufficient cooling cause of small heat pipe.

5) no solder paste on top of CPU.

6)poor manufacturing in bhima

7)leadfree solder used

Thanks to xda and the talented developers, many of us have learned a thing or two about smartphones in general by flashing firmwares and even modding our smartphones hardware for various reasons.

But even as a casual smartphone user that had many devices during the years many of us have learned a thing or two so for me once I found out about Poco x3 pros are dying it wasn't such a big shock but just another problematic smartphone/board like many in past I guess.

What I mean is that at first I wasn't sure what's happening but after using the Poco x3 pro and seeing the temperatures of CPU hitting 80c+ in some cases I was thinking is it really a surprise the Pocos are dying???

It's being years but I remember many cases of smartphones/cpus cheap or expensive FLAGSHIPS dying out of the blue specifically cause of overheating like for example the famous LG G3 using snapdragon 801 or if I remember correctly the snapdragon 821 in many smartphones and some mediatek boards having problems and more that I dont remember ATM.

If u have being flashing your androids for years and playing around you would have seen that some cpus in rare cases on different smartphones may be underclocked or overclocked or even have different thermal configurations that make the CPU throttle their frequency in order to not overheat or maybe to save battery or whatever reason.

I have seen stock smartphones throttle CPU freq at 60c or 65c or 70c but never more than that in the smartphones I happend to be using during the years.

I wasn't messing out with thermals usually but I remember my loved LG nexus 5 that when it was "older" i had flashed custom kernel and increased thermals from 70c to 80c back in the day and the smartphone was performing much better even though keep in mind that is not always the case but it just needed little thermal room.

I was aware I was risking to burn it but lasted for a year using like that and the increased performance made me delay buying a new phone.

I know it's complicated and that different cpus may be able to handle different temps but I think we can safely say in this case that's why x3 pros are dying??? I don't like say for certain but in this case that's what I really believe.

I was wondering could there be a solution maybe?

why hasn't Poco push an update to make the smartphone throttle more agressively and not overheat that much?

maybe it's not possible through an OTA update?

maybe Poco is thinking the drop in performance would be making people furious even if it was for good reason?

they just don't bother since maybe it doesn't even worth it or the percentage of failures is not that big but just seems big cause of the huge success of the smartphone in sales?

anyway who knows.

Then I thought hey.

we flash roms and kernels to customize our androids to increase our smartphones performance (with no success really in most cases let's be honest guys lol) or to increase battery life or just for the fun of it sometimes.

Why we don't use that POWA FO GUD.

Why there is not a "x3 pro saver" kernel ready to be flashed with thermal limit at let's say at 70c or why it's not a "popular solution" to flash custom kernel and adjust the thermals at lower degrees?

Maybe lowering the freq of prime core also helps keeping temps down that's something that should be tested.

Either way I wonder how there is not an attempt to make the phone run cooler than 80c but only to increase performance or battery life and such.

It will be lowering performance but some people may don't mind this tradeoff.

It can be very easy to adjust this setting on the fly so u can toast your CPU only when u really need this increased performance.

Anyway some of us have take actions to try make the Poco live longer by either using it with caution like for example, not charging while playing or while room temperature is high.

Avoid using the stock charger at 33watts.

Doing even hardware mods that sometimes go tooooooo far but actually help with the thermals.

I am one of those people and for me it's fun to play around with that stuff and now I am thinking that I want to try to do something on the software side also just to see how it will go and what the disadvantages will be in performance.

I don't really worry since I bought the x3 very cheap and even if its gonna die in one year or something it wouldnt be the end of the world for me but more like a bad purchase (**** happens).

I understand some people thought may don't have the money or maybe they worked really hard to save to get this smartphone so I hope u guys have good luck with it and it lasts long or maybe take some actions like the ones mentioned here or in other threads

I just wondered why adjusting thermals is not talked more in the case of x3 pro since there is clearly a problem?

Nothing can guarantee success but seem to make sense to try in my opinion.
