Moto Z Teardown – Screen Repair – Battery Replacement

Moto Z Teardown – Screen Repair – Battery Replacement


So what’s inside the world’s thinnest
premium smartphone? If you drop your phone and it cracks the glass,
how hard it is to replace the screen? Let’s find out. [Intro] First off I’m going to remove the SIM card
tray since there are no visible screws on the outside of the device. Then I’m going to use a heat gun to melt
off the adhesive underneath the back glass panels. It turns out that the construction of this
phone is kind of weird. Technically you can remove the screen without
popping off these glass panels but I’m going to show it anyway and then you can decide
which method is best for you. I found that the easiest way to get underneath
the back glass panel was to start at the plastic portion of the frame and dip my metal pry
tool underneath the glass and gently slide it out. Once the metal pry tool is in I’m going
to reheat the back glass to make sure that the adhesive is good and soft so I’m not
cracking anything. Once the back glass panel flips up I can just
tear it off and set it off to the side and repeat the process for the top panel. When you’re heating it up you want to get
it just too hot to touch, then you know the adhesive is getting soft underneath. Now that both panels are off I can remove
this gold bar on the bottom section of the phone. This bar is purely aesthetics; there is no
actual value to it. It’s just there for looks. Now the reason for taking off the back panel
is so you can push up gently on the screen from the back side now and you don’t have
to be sticking things deep inside of the phone, like playing cards. It gives you a little bit more leverage and
room to work with. Either way there is still adhesive all the
way around the edge of the screen so I’m going to warm it up just like we did with
the back glass, and then slide my metal pry tools around the black side of the glass,
making sure that my tools do not touch the screen where the display is because metals
and displays do not go well together. It will crack very easily. You’ll see how thin this screen is in a
second. Once I have all of the adhesive cut away from
the sides, the top and the bottom, we can see how the screen is connected. Definitely go slow during this part and reheat
the screen as often as needed, getting the glass just too hot to touch. The part that you have to be careful with
is down here at the bottom of the phone. That’s where the ribbon cable is for the
display. Now if your screen is already broken, obviously
you don’t need to be as careful as I am, but I’m going to reuse my screen so I’m
taking special care not to damage it. Now this screen has the same Lego-like connections
that we see on most every other phone except Samsungs and iPhones. So we’re going to remove the protective
metal covering and unsnap the screen like a little Lego from the motherboard. Make sure you stay organized with all your
little parts. There are a couple more components inside
that we’ll be taking out so make sure they don’t all get mixed up. So here is the glass screen. It’s got the glass and the display panel
fused together as one. And this is what your replacement part will
look like when you purchase it. Although it will probably have new adhesive
surrounding the top, the bottom and the sides of the glass. I will link replacement parts and tools in
the video description below just like always. Now let’s see what else can be replaced. I’m going to set that metal bracket off
to the side and then pull off this tape that’s covering the battery and the motherboard. Set this off to the side. You can try to reuse this if you want, but
it’s pretty flimsy stuff. There are 2 screws holding the front earpiece. They are T4 with this particular bit set. Remove these two screws and then the earpiece
can pop up and off of the phone. It has the two little contact points that
rest on the motherboard so it gets its signal. There’s a random plastic piece right here
underneath the side button cable. This is where the power and volume button
connect to the motherboard. The battery connection is down here underneath
this plastic piece. We’ll slide this out from the bottom and
then set it off to the side. And then we will unclip the battery, snapping
it off just like a little Lego, similar to how the screen was. Now the battery can be lifted out from the
bottom of the phone. There’s nothing underneath that can really
be damaged, just the back metal plate. Just make sure you don’t bend or puncture
this battery. Lithium ion batteries can explode as you can
see from my Note 7 Battery Explosion video. There are two more screws down at the bottom
for a total of 4 screws in this entire phone. Usually there are a lot more. The bottom plastic piece pops up and out,
and this just kind of sits around the charging port. There is a metal plate over the processor
and the memory. We’re going to pull that off just so we
can see what it looks like. There’s really nothing that can be repaired
under here. We can see now though that the charging port
is not replaceable. It is attached very securely to the motherboard,
so unless you have micro-soldering skills, you’re just going to have to leave it in
the phone. The rear facing camera can be swapped out
pretty easily. Just lift up the little latch and slide it
out, similar to how all of the other cameras are held into place like Samsung. We can see it has the OIS stabilizing as well. It’s kind of like a little gyro that sits
inside of the camera unit to stabilize your videos and your pictures. There is one more big screw holding the motherboard
into place. And then surprisingly the motherboard does
not want to come out from the back of the frame. I assume that it’s secured very permanently
to the back. I could be a little bit more aggressive with
it, but the more you bend a motherboard, the more you risk cracking any of the little tiny
solder joints that you see around all of those little resisters and processors. And I don’t want to damage this phone permanently
so we’re just going to leave it in the frame because there’s pretty much nothing here
that the common consumer can replace easily without special micro-soldering tools and
microscopes. Let’s put the camera back into place. Tuck it down and clip it in. Reassembling the phone. Put this screw back in as well. The protective plate over the processors and
the memory goes back into place and the little tiny plastic bracket down at the bottom near
the charging port. Two more screws for that little plastic bracket. And the earpiece goes into place. It will click in. Battery gets tucked down into place and you
can plug it in once everything else is plugged in on the board like the little side buttons
for the power and volume. I’m going to slip this little plastic bracket
back into place and this just kind of puts pressure onto that little connection so it
doesn’t pop off if you ever drop your phone. I’m going to reconnect the screen. This is where you’ll be using your new screen
if you’re doing a screen replacement. Just plug it in; you’ll feel it snap underneath
your fingers just like a little Lego. And then the little metal bracket goes over
the top of it, making sure each little clasp goes inside of the frame so it doesn’t pop
out ever if you drop your phone. It’s important that this is secure. Remember that your replacement screen will
probably have new adhesive so you’ll want to peel off the protective adhesive covering
so that it will stick to the frame of the phone. I’m going to fold the screen back down into
place and set it down, and push it firmly to that the adhesive will reconnect. Remember that bottom decorative metal piece. We’re going to tuck that in and clip it
down. And then the back glass pieces can go into
place as well, if you decided to use the route that required the removal of the back glass. Top glass gets pushed down into place as well. It fits very securely back here. We can put back in the SIM card tray and we’re
good to go. If you have any questions leave them down
in the comments. Don’t forget to “like” if this video
helped you. And remember all of the replacement parts
can be found in the video description of this video. All my behind the scenes and future projects
can be found on my Twitter and Instagram. I’m definitely looking forward to the iPhone
release this week. The iPhone 7 should be an interesting project. Thanks for watching. Hope to see you around!

  1. Look to make it short y have a moto z and i want to put the moto z play batery o te moto z one.
    Can you explain me how do i do that ?

  2. what heat gun do you recommend for projects like this. I recently started doing android phone repairs and need to buy one. Thank you!!

  3. …for what it's worth…after refitting the digitiser, but before screwing it all back together, I think it would be advisable to power-up and leave running for 15 minutes, or so, just to make sure that it works!
    Just saying….

  4. I have this phone and the screen is popping out on one side. What kind of adhesive should be used when repairing a phone?

  5. What about a replacement battery? And what would happen if the phone gets so hot you cannot touch it when it's charging?

  6. Would you agree that after going through all that process the phone will no longer be water resistant? Can more adhesive be added to reinforce the original adhesive?

  7. This video comes really handy now that there are hundreds if not thousands of faulty Moto Zs with broken batteries that MotorolaLenovo are not willing to replace or repair without charging us.

  8. Throw it in the trash where it belongs , unlike a Lego which is somewhat useful. If you own this piece of shit and it actually does work, chances are it won't work when it downloads android 7.1.1 "instant battery death version". Can we start a class action lawsuit? Barely over a year old and the battery drops 2% a minute. How can they not recall this with all the complaints and people give Apple a hard time?

  9. I have this phone and love it. Very good video as always thanks for the information and learning experience.

  10. Sorry to say but the little gold bar on the back is not just for looks. It is part of the connections for moto mods, without the gold bar on the mod and phone lining up perfectly, the mod will not work.

  11. Great video.  Where I can get that battery? I have the normal moto z model XT1650.  I live in Ecuador in South America.  Thank you.

  12. Hey Jerry
    Can we get some explanation about display and digitizer disassemble and reassemble process for smart phone…
    Thank for Tech

  13. Hi, is it possible to remove the screen without damaging it? I removed one an then the screen has stains and the touch panel doesn't work

  14. Replacement displays don't appear to come with new adhesive now and it's hard to find a good adhesive anywhere.

  15. You're supposed to open the screen to the side like a book. It swings open using the right side as a hinge. Both the screen and fingerprint scanner flex cables are designed to do this.

    Nevermind, seems like the US version (mine) is different.

  16. Will the adhesive be the same as it was before removing parts or will the back two pieces fall off while I use the phone

  17. Has anyone replaced their screen and then had issues with their speaker? Mine sounds very muffled. I opened it back up and if I pry the front part of the speaker a tiny bit, the sound is full volume, but as soon as I release it it snaps back down to the old, quiet, muffled position. Any help would be greatly appreciated.

  18. Well I dropped my phone this morning and ran over it screen won't come back on just wondering it dented it pretty good if it would be worth trying to take to somebody and have it fixed it's only about a week old?

  19. Worst phone ever created .weak Battery . Back Camera gets scratches instantly . Finger print magnet . Weak screen . And apperantly if u run a movie while it's being charged it might burn ur house . Heats very quickly . When It fall on its back not only the back side breaks the front as well

  20. I have this phone I'm am on my 2nd replacement because the battery keep going bad I don't not recommend this phone at all it sucks

  21. Tried to replace the battery on this brick of a phone.. this video sure makes it look easy. I bought the tool, bought a battery, ended up breaking the glass trying to get the tool in on the first step. Sliced up my palm pretty good with the tool. Out $40 and went HRC on the phone with a hammer. Good times. Definitely my last Moto phone.

  22. Hello I have the same phone and the battery is bad is it possible for you to replace the battery if you can I will buy the battery and if you need anything else just ask I wanted you to do it because I've seen all of your videos and i trust u but if you can't then I understand

  23. Is it possible to take the screen from a donor Droid XT1650 and put it on one with a cracked screen? I have two, one cracked screen, the other with a dead battery.

  24. Jerry: "… only around the BLACK side of the glass… making sure that my tools do not touch my screen…"
    Me: Okay, I have to be very careful now… aaaaaaand its broken… 😀

    damn… now I need a new phone but still a good DIY video anyways… 😉

  25. I did it. Slowly, as you described. Replaced battery (Chinese damn it!) with new one purchased. 3000mAh, charging as new. Phone works just fine! Charged to 100% in about 1h 45min. Accidentally damaged front torch light, but everything else works great! My regards! For all those who gave up from this phone, buy a new battery and give it a try. Just go slowly!

  26. I needed to see how to resolder one of the pins on the back panel. dropped my phone and one of the pins broke out. Now none of my mods will connect. How do I fix it?

  27. I need a new screen for my Moto z play where do you suggest me to get it? It completely broke the screen is completely black now.

  28. What happen if heat gun discolored the Screen, does it heals back? if yes, how long to it take before the burn mark goes off?

  29. Hi, very good video. I have one of these phones and need to replace the battery. This and other videos are going to help me do that.

    That being said, please be aware that the "decorative metal piece" is NOT DECORATIVE. Do NOT damage that piece! I am an electrical engineer who has worked in mobile phone development. That piece is for GROUND. It is important that this have a good connection to ground or the mods attached to the phone may not work reliably. This is especially true if you are using a battery mod. As an added bonus, this ground plate offers ESD (electrostatic discharge) protection. To everyone disassembling this phone, please be careful with this part.

    Another side note: you called the copper tape over the processor/etc. on the motherboard a "protective piece." This is true, but it should be noted that it not only acts as a heat spreader for the chips, but it also provides electromagnetic shielding to prevent electromagnetic interference (EMI).

    Regardless, thanks for the video! It is very helpful to see someone disassemble the phone, especially when it comes to the heating of the glue, which is almost an art it seems.

  30. Has anyone changed just the battery and kept the screen intact? Love this phone but I raped it over this last year when I switched from Gapple to Droid and the battery is tired. Just wondering if I should just get the screen with the battery. Or, just spend the $380 CDN and buy a new one. $380/year isn't bad. Plus I am too busy fixing crappy iPhones for people.

  31. It's nearly impossible to repair this phone. The parts supposed to slide or pop of etc are so stuck after 2 years that you nearly have to breake them

  32. I'm watching this with a moto Z that has a broken back glass panel and it's broken enough to see the mother board

  33. Think this video is partially…can't say fake but not exactlly true..
    First of all a pretty thick metal pry tool is much more "dangerous" when dealing with a this display like that..then a 100% plastic playing card whitch is far slimmer and thus far safer to use..
    Second, the adhesive on the top and bottom side of the phone is much more "resilient" then shown on video.. takes repeated tries to remove it, doesn't come off after a single swop with that pry tool..
    And third in order to move safelly you have to reheat every portion of the screen to take it off (just like he said but only heat it once!)
    My guess is that the display was already removed and most of the adhesive taken off prior to making the video, so he had a much easier task then doing it with a phone that hadn't been worked on before..
    Anyway his technique is good , but procedure is a bit harder then shown on video..
    Cheers!

  34. The adhesive on my phone is toast. The glass is lifting off so I can probably just lift it off, it's had a crack in the corner for about a year. Perfect time for a new battery too. Thank you ♥

  35. Is it possible to replace whole inner electronics, without, replacing the Frame of phone? And which way is to replace Frame ? Thanks !
