Poco X4 GT / Redmi K50i / Redmi Note 11T Pro Disassembly Teardown Repair Video Review

[@fohoho475]

"Sir, my phone, the Poco X4 GT, continues to drain battery noticeably even when not in use. Even when I turn it off completely, it still loses power. For example, if I leave it at 99% before going to sleep, I wake up to find it at 30%. Since you are experienced, I kindly ask for your advice on how to solve this issue."

[@speedoflight33]

i've been waiting this. thanks

[@PBKreviews]

You're welcome :)

[@somayough]

I think Poco made some claims that they increased the cooling solution of this phone, but the vapor chamber seems more or less identical in size to the one in the x3 GT. No wonder this phone doesnt really perform well in terms of thermals, the D8100 is more or less left thermally unsupported.

[@PBKreviews]

The vapor chamber is longer in length, however the X3 GT looked to have more thermal paste in between the frame and the copper heat transfer tape on the back of the board. The X4 GT has a good amount of thermal paste underneath the copper tape between the processor and the copper film, but not so much between the film and the frame.

I'm using poco X3 nfc right now i would like to upgrade my phone what is your best recommend phone for upgrade? Im planning to buy F3 or X4 gt ☺️

[@somayough]

@@adrianjuliano9744 Unless you need the headphone jack, I think the F3 is still a better deal overall, especially if you can still find one on sale. The F3 has the worse camera of the two, but you can install GCAM mod to get better processing for your photos(since the X4 gt has a mediatek chip, gcam will likely not work).

[@kamwardmama-o2424]

How long do thermal paste last in phones before replacing it ? I have realme gt neo 2.

[@PBKreviews]

not too sure honestly. There are many different types and kinds. Some last longer than others but again the length can also depend on how often your device is used or to what extent its used.

[@bgbore96]

The thermal paste most definitely will outlast the phone's life span. On the computers it lasts for several years, 4-5 and more.

Hye, thanks for the video. Wanted to ask a weird question. Is it possible to mod the sim reader slot so that it can also read sd card? i can put any third party sim tray which has support for sd card. I love this phone but sadly no sd card slot.

[@PBKreviews]

Hi, no I don't think it would work. Would not only require additional solder points on the board but additional resistors and such to detect and read, and also software mods I would assume.

Hello, Thanks for the video. I have one question. I have this device and I'm seeing a crack with small bump below the crack, just half an inch below the camera module. Is this a fauly battery or motherboard issue? Also what can be the probable cuase? Thanks!

[@PBKreviews]

It's possible it can be from a bloated battery. The cause can be many things, from drops to overheating or just a bad battery.

[@nesugatv7254]

Li-on battery??

[@tahabahaapeer3234]

Is the ram under the board? I hope it is not like poco x3 pro So that you don't destroy the rose quickly

[@chaomatic5328]

Since the charging board is removable, do you think it is possible to make a diy upgrade from usb 2.0 to usb 3.2? I often plug my Poco X4 GT into my PC, and the transfer speeds are slow, not to mention hdmi adapters not working. I've heard that the chipset would limit the speeds, but since the entire sub board is removable, could this be circumvented?

[@PBKreviews]

I'm not sure since I'm not an expert in electrical engineering but I would assume just changing the port alone would not work since there are controller chips regulating it as well either on the sub board itself or the main board.

[@falicmon9566]

hello, i have a back cover hello, I have a poco x4 gt back cover that bends in the area near the inscriptions,this is normal??

[@mihailm306mm]

Hello, I'd like to inquire, if bottom micro has some kind of protection or may be it is installed 90° towards the bottom edge? There is a point that firstly i inserted a simcard but then i needed another one to be inserted, and occasionally put the needle into the microphone's hole. I barely touched it and didn't push it further as i quickly understood it was the wrong one. However I'm a bit anxious of having smth damaged. Overall, i checked wether the micro works okay, and yeah, it does. But who knows, may be it can cause some problems with water/dustproof condition

[@PBKreviews]

Hi, no you will be fine. The filter and mic are both seated above the hole so they wont be damaged.

[@kevin69hshshs]

Battery size?

[@kielgalo4119]

can i ask clarifications? is its frame made of plastic or aluminum? cuz currently i own poco x3 nfc for almost 3 yrs i guess?,and your teardown video convinced me to buy this one for a plastic back, aluminum frame and gorilla glass front is really my gold standard of build combination, my poco x3 had survived a lot of drops, rolls, bents and many more torture out there without a case, it's such a strong phone not even a scratch on screen or major dents on edges,, and im edging on this poco x4 gt for my upgrade though

[@terabytedesu]

whoa! no thermal paste between cooper and graphite film from the back. i wonder adding more thermal paste on front and back can improve thermal management

[@PBKreviews]

I don't think it would make too much of a difference for the back, since mainly the thermal paste will come into play for transferring the heat to and through the frame not so much the copper tape and graphite film on the back.

[@gucky4717]

The Back is not good for cooling since it is made from plastic. As with many other phones the Display is the main heatsink.

[@yourcommentgotabyjames3238]

Strange.. on GSMarena site, F4 and X4 GT have a li-po, but both have li-ion battery...🤨

[@PBKreviews]

Hi. It is a li-po. The way they label the batteries, if its a li-po then its written lithium ion polymer, if its a li-ion then it will just said lithium ion. But either way the lithium ion potion is always labeled on the batteries.

[@kantipoddar]

Brother one question... How much quantity of thermal paste should I buy to apply on Poco F1 phone. Also if some paste is left over, can I apply it over camera and battery?

[@PBKreviews]

Not sure how much, usually they sell them in standard amounts which is more than enough for any application. However I wouldn't apply thermal paste to areas that it doesn't need to be like the battery and camera. Depending on each thermal paste compound, some are more conductive than others and if they leak into areas that you don't want them to be, they can short the phone or damage components.

[@kantipoddar]

[@PBKreviews]

There is a high chance the ROM would be damaged from corrosion as well rendering it useless, but even if it was good, you would need to find a specialty shop that can de solder and remove the ROM from the board and re solder it to another board. It wouldn't be cheap if even doable.

lol no it won't explode, if it overheats it would probably notify you and it would either shut the device off or pause the activity until the phone cools down. But generally most phones will heat up since heat is being exhausted from inside out to cool off the components. :)
