today we're going to take apart the lumia 950xl it's the same size as my no.5 it's actually one of the more interesting phones that I've taken apart recently and I'll show you why in just one second first things first turn off the phone the back of the phone is removable so just put your fingernail underneath the back cover and pop it off and this exposes the Qi charger and the battery the battery is at 3300 milliamp which is quite a bit bigger than the note 5s 3000 milliamp battery now there are twelve Torx screws and the back cover they are a size t5 it might be a t4 as well just depending on what screwdriver set you have there are some variances from the Chinese manufacturers that remove the back panel you put your tweezers underneath by the charging port then you lift up their little clasp underneath the camera as you can see from this angle here now here's the interesting part it's got some normal stuff under there like the earpiece in the loudspeaker and the flash of the camera and then we have this beautiful copper snake light component right here this is actually the water cooling we got the evaporator and then we have the condenser pipe so the water heats up inside of the evaporator as it rests next to the processor and either evaporates or gets hot and goes up the pipe and then as it cools down from the copper it will travel back down the pipe into the evaporator again to recycle the process even if the water cooling itself isn't super efficient having a copper heatsink that large has to be helping the heat transfer just a little bit you can see here where it rests on the motherboard on the opposite side of the processor one other cool aspect of this phone is that the SD card reader is removable similar to some of the older no phones you can just unsnap it with this little Lego light connector from the motherboard and it's easy to put back on as well since this phone isn't super popular parts are hard to find but I will link the parts that I do find down in the video description below here is the vibrator motor it's got the dual sizes on it so it gives a more full vibration go down snap this little tiny ribbon cable from the side and then here is the five megapixel front camera it's got the same Lego light connection that all of the other connectors do on this board we're going to remove that it's semi attached to the infrared retina scanner I'll talk about that in just a second there's two ribbon cables for the screen that are on the motherboard gonna unsnap those here's the headphone jack also removable then the motherboard is clipped into the plastic frame there's a series of Clips around the outside so just undo those and in the motherboard will pop of the frame before you get too far though you do have to remove this sticker that sits behind the battery because there's one ribbon cable that sits on the back of the motherboard right here once that snapped off the motherboard is free from the phone and we have access to the rear camera here is a 20 megapixel rear camera and here's where that heatsink sits on the back of the processor here is the charging port it is a Type C charging port it is not removable it is soldered very securely onto the mainboard so unless you know how to solder it's not going anywhere now here is the infrared iris scanner so the phone itself can just scan your eye and then unlock the phone it's used for Windows hello now here's the screen component itself now the ideal situation would be to find the screen which is the glass and the LCD and the frame sold as one unit but if you cannot find it sold as one unit it'll probably just be the glass in the LCD in which case you have to harvest your old frame of the screen and use it with your new one you just use heat to separate the glass and LCD from the old frame and then use the adhesive to apply it to the new LCD and glass it does take a bit longer and your old LCD will not survive the process so make sure your new one works before doing it going to reattach the rear camera and that one small ribbon cable on the back of the motherboard and then set the motherboard down into place pressing it down into the series of clasp along around the outside here's the headphone jack and clip that down into place you'll feel it snap down like a little Lego here's the five megapixel front camera going to clip that in first and then you can just fold it over the top and press it down into the frame where it belongs going to clip the screen ribbon cables down into place as well and the small ribbon cable on the side of the board next to the vibrator motor and the sticker goes back into place resting right over the top of those ribbon cables then the back panel along with those 12 torques screws battery goes into place and the back cover if you have any questions leave down the comments don't forget to like if this video helped you and don't forget to subscribe does mean a lot to me obviously around
