Sony Xperia Z4 Disassembly _5The Sony Xperia Z3+/Z4 is a marvel of engineering – we remain in constant admiration of how Sony marries such elegant hardware with the sheer amount of technology crammed in. The disassembly pictures below give a small insight in how Sony’s latest flagship is put together. If you are curious to see what’s inside, check out the pictures below.

Xperia Z3+/Z4 disassembly

Sony Xperia Z4 Disassembly _1

The first step is to open the flap for the nano SIM and micro SD memory card tray.

Now the back glass needs to be removed by using heat at the edges to soften the glue. Then use a guitar pick with the back panel to remove it successfully.

Sony Xperia Z4 Disassembly _3

Here you can see the layout of the components in the Xperia Z3+/Z4 versus the Xperia Z3.

Sony Xperia Z4 Disassembly _4

The 3.8v 2930mAh battery can now be easily removed. Also, the connectors for the motherboard can be released.

Sony Xperia Z4 Disassembly _5

The motherboard can then be removed by taking off several screws using a screwdriver.

Sony Xperia Z4 Disassembly _6

All Xperia Z3+/Z4 components located at the top of the handset can now be removed. This includes rear/front cameras, headphone jack, earpiece speaker and securing covers and brackets.

Sony Xperia Z4 Disassembly _7

Here we can see the 3.5mm headphone jack, which has waterproof foam around it. This is to keep internals protected from the open jack when exposed to water.

Sony Xperia Z4 Disassembly _8

The earpiece is placed at the top of the frame with a waterproof sticker.

Sony Xperia Z4 Disassembly _9

Here you can see the larger 20.7MP rear camera and 5M front camera.

Sony Xperia Z4 Disassembly _10

Components shown below include the charging flex, main flex, sensors assembly, vibrator motor and loudspeaker.

Sony Xperia Z4 Disassembly _11

Sony uses a waterproof rubber seal around the exposed micro USB port to ensure no water leakage inside.

Thanks nfs2010!

    S6 vs Z3+ heat test: ?????????? ?????

    s6 vs Z3+ speed test: ????????? ?????

    ????????????: winner Z3+

  • nfs2010

    Thanks! Lol – In that video, Z3+ is embarrassing Galaxy S6 in low-light shooting & turning out to be cooler after doing longer 4K recording – LMAO. Ah, Samsung’s media pals just keeps on fooling the idiots =)=)=)

    Dear XB, I think it’s time for you speak up and do some comparisons like this to show
    us what kind of dirty game Samsung sponsored media is playing.

  • Abhinav Tella

    The one fact that is not observed is that the S810 throttles a lot more just to maintain those temps. The Exynos can maintain a higher performance profile.

    Best way to prove this is run a long benchmark…. You will see the S810 drop more in performance than the beginning of the test compared to the Exynos.

    The fact is we are comparing a 14nm process to a 28nm process. To put in other words a small dot at 60C compared to a patch at 60C you will notice the patch more…. This is the core temp not what you can feel.

    The S820 with 14nm process I’m sure will rectify the issue.

    There have been multiple articles out including a recent one showing compared to S801/S805/808/Exynos the S810 throttles the most under load by far…

  • Akand

    This is what I want to explain Timel. This is nothing, but the game of dirty media.

  • nfs2010

    810 is made in 20nm planar mosfet process (not 28nm). S6’s Exynos 7420 is made in 20nm with Finfet (keep in mind that it’s being marketed as ’14nm’, but it’s not a true 14nm as it’s using 20nm backend) Only intel has a true 14nm process

  • Damn

  • luigi

    ddr3 ram?

  • nfs2010

    I think it is DDR4. Check out the second post at this XDA thread

    Looks like 810 doesn’t even support DDR3

  • spade

    I’m impressed that Z3+ was able to record 4K longer than GS6, i think that was probably due to the HEVC capture on Z3+ compared to GS6 with the old AVC capture, i might be wrong though.

  • dinesh

    where’s the fucking timel….

  • Abhinav Tella

    Thanks for the corrections :).

    As for comparing the Exynos 54XX 20nm vs Exynos 7420 14nm whatever those backend changes you mentioned led to a significant reduction in cpu core sizes, meaning less current leakage.

    Also could you explain further regarding the “backend”, I have not heard this before, seems interesting.

  • Jecht_Sin

    Amazing. And then I feel proud when I fit the grocery in one single bag. lol

  • nfs2010

    No problem. Take a quick look at this

    Backend (BEOL) is basically the ‘via’s. The transistors, diodes, etc at the bottom are front end. In order to take advantage of the smaller process, you need to shrink both & shrinking backend is just more difficult :)

    At the AT link you gave, check out the density figures for last three processes. As you could see, the shrink mostly comes from the backend shrink from 20nm LPE to 20nm LPM & M1p remained unchanged at 64nm on the 14nm. So that means it’s not a true 14nm process. If you check out the first table from the my semiwiki link, you’d see that TSMC also has the same 64nm M1p on their 16nm process. Only intel was able to give a proper shrink to M1P (52nm).

    Also, “reduction in CPU size” doesn’t actually mean less leakage in standby. It’s actually the other way around as transistors become leakier when they get smaller. The “less leakage” actually comes from the Finfet.

    Hope that helps!

  • Abhinav Tella

    Hey thanks, pretty good explanation.

    So what is your take on the throttling difference between the Exynos and older Snapdragons vs the S810 under load?

  • nfs2010

    I ran antutu 5/6 times consecutively on the Z3+. The last score was about 10% less than the first one. You’d get a bigger drop on Exynos – try it out yourself.

  • Abhinav Tella

    Interesting, will do. Also is this after the latest update?

    Good discussion so far, thanks for clearing the other stuff.

  • nfs2010

    Yes, previous fw was horrible !

  • ramuk

    LOL, Fucking Timel is hiding like cockroach.

  • hmmm

    and my z3 screen just went off…what are you doing Sony???after just 8 months of use and no water contact!

  • Rizky Maulana

    timel i love u :*

  • dragonsneeze

    Wow, didn’t know that. Interesting. Thanks. :)

  • Clarence Alvarado

    Still no sign of 4K HEVC recording. Z3+ still using H.264

  • Raj Singh

    Nicely done.

  • spwx

    lol so much for that… not only S6 cant focus in dark light, it overheats much sooner than Z3+….

  • gamer324

    Sony has yet to implement it, even the s810 supports it on a gpu-level.
    Pretty darn impressive performance by the z3+ overall. Seems Sony has already sorted out the overheating issues in the camera app with that recently launched update for the z3+, from here on out hopefully it will be smooth sailing for Sony.

  • gamer324

    Even low-powered SoCs like mediatek’s mt6582 and lower end snapdragons see a bigger drop than that. That is amazing consistency, did the phone feel any jerkier/more throttled in usage after that? And what was your Antutu score?
    Really really pleased to see the z3+ perform so well. Definitely the best phone this year thus far.

  • Shubham Mutreja

    Also this xperia doesnt use any samsung part look at that!!
    The memory chip is from toshiba and ddr3 ram is from pop?

    I’m here ^_^

    Just don’t get why do you have to call for me

  • Timel

    Don’t you think these are fake or edited videos?

    That’s so funny when there’re good videos about Xperia phones you believed them but when there’re bad videos about Xperia phones you denied and didn’t trust them LOL

    Like i said, Xperia brainless fanboys here just want to believe what they want to believe.

  • Akand

    Same here!! Whenever you see good things about Xperia, it seems fake to you. And whenever you see bad things about Xperia, it seems undoubted true to you.
    Like I said, you’re a brainless review reader without any practical knowledge. Xperia devices maybe not the best, but they’re decent to stick with.

  • Mathias Cronqvist

    Flag and ignore, dude. Maybe that way his owner can put him back in his cage.

  • Mathias Cronqvist

    Why would you want to explain anything to that thing? You need some sort of rational thought to process explanations.

  • nfs2010

    It didn’t get jerky after 40 minutes of real racing 3 gameplay. It did get warm though. Antutu scores vary from 53K to 47K in my case over 5/6 consecutive runs.

  • spade

    Well then, maybe they will provide that on 5.1 update later, or not that will be wasting such a hardware. thanks for the info btw.

  • spade

    As always, Sony just being Sony.. Anyway good to hear that Sony already fixed heating issues on Z3+.

  • Akand

    I know he is too rude to be flagged. But I can’t flag anyone as long as he’s not too impolite. Sometimes my mind thinks his comments don’t bear hatred rather anger and disappointment. Maybe he also loves Sony and wants to see Sony on top all the time. But Sony fails to reach at such level and he gets anger. That’s why he talks like that.
    But his madness has reached at such level that he should really be ignored at least.

  • gamer324

    That is very impressive indeed, that also puts the Xperia z3+ among the top performers with an s810 SoC.
    And as you say, real-world performance seems to be a breeze. Overall Sony has again made an outstanding all-rounder of a device. Too bad the launch firmware caused so much bad press though.

  • Mathias Cronqvist

    You give it way too much credit, it’s just a dumb, dumb thing that’s infecting Xperia Blog. This is probably the only way it gets attention, it’s probably bullied in school, insulted by its family and I can’t say I blame them.

    Amd why you guys hate him? I’m curious here :D

  • jorma

    Any idea what is wrong with my xperia Z3 plus? i dropped it and the screen was totaled, phone was still on until i switched it off. i ordered new lcd and digitizer and installed em. Now when i try to start the phone it won’t start, no light or anything is seen even when i put it on charger. only thing that heats in the phone is the chip that is connected to phones vibrator motor + motor heats too. they both are very hot to touch and start doing that as soon as i connect the battery. i’m quite baffled.
