Galaxy Note 8 teardown shows off familiar innards, a battery that (hopefully) won't explode

The Galaxy Note 8 will go on sale starting September 15, and a few customers are already starting to receive their units. The folks at iFixit have managed to get their hands on a unit, proceeding to tear it down to give us a look at the innards.

Galaxy Note 8 teardown

With Samsung switching to an extra-tall Infinity Display, there's more room to house the internal components. The company opted to go with a 12.71Wh battery (3300mAh at 3.85V) on the Note 8, which is 6% less than the one it used in last year's device and slightly more than the 12.32Wh (3200mAh at 3.85V) battery featured in the Note 7 Fan Edition.

Like previous years, the battery is sealed in with copious amounts of adhesive, but Samsung moved the location of the battery to dead-center at the back, with the vibration motor now located at the bottom right.

The phone has a total of four cameras — a front 8MP camera complemented by an iris scanner, along with two cameras at the back. Samsung's dual camera setup at the back consists of a wide-angle lens and a telephoto lens, with both sensors offering OIS (which iFixit was able to confirm).

As for the rest of the hardware, the Note 8 features Samsung's own LPDDR4X memory module and UFS flash storage, Avago's ICs, and a whole lot of Qualcomm components:

  • Samsung K3UH6H60AM-NGCJ 6 GB LPDDR4X SDRAM layered over a Qualcomm Snapdragon 835
  • Samsung KLUCG4J1ED-B0C1 64 GB UFS flash storage
  • Qualcomm WCD9341 Aqstic audio codec
  • Skyworks 78160-11 power amplification module
  • Avago AFEM-9066 power amplification module
  • Wacom W9018 touch control IC
  • Qualcomm WTR5975 RF transceiver
  • Avago AFEM-9053 power amplification module
  • Skyworks 77365 quad-band GSM/GPRS/EDGE power amplification module
  • Qualcomm PM8986 PMIC
  • Murata KM7628048 Wi-Fi module

The phone retains the 3.5mm jack, and the port is completely modular, which means you'll be able to replace it with ease should the need arise. The front-facing sensor assembly is also similarly modular. The Note 8 uses Phillips screws for the mid-frame and the NFC antenna, which should make it easier to conduct repairs.

However, the 6.3-inch display and the rear glass panel are held together by a large amount of adhesive, and the fragility of the panels means it'll take a lot of effort to access the internal hardware. Overall, the phone picked up a repairability score of four out of 10.

  • I don't have my unit yet, but I've been waiting for this regardless. I especially like the battery placement being dead-center. (Also, a minor request- put repairability score in the article so readers don't have to click through to the teardown page itself to find that. It got a 4/10, for anyone curious!)
  • Added that in. Thanks!
  • Wacom W9018 touch control IC
    This is what sealed the deal for me! Fantastic digitizer. Still unmatched I the industry in any other manufactured phone. Spen diodes it again 4096
  • DON'T BUY THIS PHONE, This is really a total bunch of crap WE HAVE WAITED and get a NOTE 8
    With a NOTE 4 battery for twice the price of the note 4, your a fool to buy this note 8..the S8 plus has bigger battery and $300 dollars cheaper.. hopefully if south Korea is still hear next year Note 9 will have that 4000 mah battery & dual fwd speakers..
  • I hear you about wanting a larger battery however I have not had a phone die before the end of the day in a few generations. I did have a few spare batteries three and facts for my Galaxy Note 4 and Galaxy Note 2 my Galaxy Note 3 only had one battery. I thought I would miss the extra batteries but wireless charging and more efficient phones negated this(for me )and as far as front facing speakers are concerned I have never really wanted that in a phone because I usually use headphones or Bluetooth headphones or I have my phone connected to wire or bluetooth to a big speaker that will play much nicer music like my Bose mini SoundLink or a car.
  • The biggest downside to this phone IMO is not the battery (though I share some concern there), but more about the lack of support for T-Mo's new 600mhz spectrum. I realize T-Mo is only...what...1/4 of the market, and 600mhz probably won't be widely available for another year, so it may not make a huge difference. BUT if you spend $950 for a device, I think it's fair to expect it to last for a 2 year cycle, which means you'll be missing out on 600mhz the last half of the ownership period. And T-Mo is still a large segment of the US customer base. Large enough that LG considered it when choosing the processor for the V30. My 2 cents.
  • I get what you are saying, however, 600 being deployed in your area doesn't mean the phone suddenly stops performing like it has before.
  • True. But it DOES mean it won't perform as well as other devices with 600.
  • correct, I agree
  • Qualcomm has confirmed that the snapdragon x16 modem paired with Qualcomm WTR5975 RF transceiver will support 600mhz. Hopefully they are able to release a software update to turn on that frequency when they're ready, or maybe by rooting it? I remember when LG released the nexus 4 the LTE radio was turned off and the only way to turn it on was by rooting the phone. I doubt samsung would let this opportunity go if the x16 modem supports that 600mhz frequency. Time will tell.
  • Not possible.
  • Tmo Currently lists the Galaxy S8 Series to support the 600Mhz Spectrum, So since the Note 8 is the exact same hardware, how would it not support the new spectrum, The way I understand it is the Phone does support it but it is not enabled, however will be through an update at a later time. and as for LG, I have owned a V10, and a V20, and Im Not impressed, I went to the V20 after the Note 7 Failure, worst decision I could have made, This thing is a pain in the ass, I will not buy a V30, I dont care if it has the low bandwidth spectrum enabled out of the box or not, the first 2 were under par phones, in both performance and craftsmanship, Partially due to the Snapdragon 820, that seemed to have an issue with heat. My S7 experienced similar problems, and so did my Note 7, but no were near as bad as the v20 and the G5. Just my 2 cents added to your 2 cents, Woohoo now we have 4 cents.
  • Not possible. It's not a matter of enabling it or updating software. It requires different hardware components.
  • i have the same problem. T-Mobile is turning on 600 mhz in Maine, including the island where I live, so it is a must have for me. Before the Note 7, I refused to buy a phone without a removable battery partly because we like going camping off the grid, I finally broke down and ordered my beautiful blue Note 7, and that didn't turn out well. Now I'm stuck with with the LG V20, which isn't my favorite phone.
  • Note 4 lasted over 24 hours, so did the 5 with a smaller battery, why would I not buy this? Not to mention you're comparing a sale price to a new phones retail price. There is less than a $150 price difference at retail between the phones. Oh, and with trade in deals, the Note 8 is actually CHEAPER for me to obtain than the S8+ right now.
  • The battery last just as long as the S8 Plus I've watched the review videos on the Note 8. I got half off my Note 8 because I had the Note 7 Plus $430 of free Accessories with my Note 8 so I'm pretty happy with my purchase of the Samsung Note 8. I will be getting the Note 9 when it comes to plus for my back up phone I'll be getting the IPhone 8 I sold my Samsung galaxy s8 plus and my IPhone 7 Plus to get this phones. Good luck in waiting for the Note 9 next year maybe it will have a 4000mah battery!
  • I'm happy with my S8 so i wont buy that note 8, Just going wait till S9 comes out next year sometime.
  • At the end of the day your giving $950.00 for a 3300 MAh battery THAT WILL NOT handle the drain
    I think in 8 months there will be a lot of pissed of people with a note 8 on the charger.. Hopen I'm wrong ...
  • Let's see how this pans out but it is not the battery when I'm buying when I buy a phone. Take a consensus of battery volume on all the phones that are in the market right now as flagship phones vs screen on time. We have yet to see the Note8 performance figures but I'm sure the owners will be vocal. I own one. I will be one of them. Look on YouTube in the meantime for drain tests and comparisons. I will stick to the real world
  • I hear you about wishing for a larger battery, that said I am going on day 2 with my Note 8 and so far have found battery performance on par with my S8+ (S8+ battery performance had degraded a tad but not really a problem). As to cost, I would rather it have been less but this seems to be the direction all top tier phones are heading. Sad but true. i really like my Note 8 so far (I have had all prev note versions). Everyone is free to form their own opinions These are simply my thoughts and observations. Cheers,
  • Bull, you already are wrong. Educate yourself bud
  • "At the end of the day your giving $950.00 for a 3300 MAh battery" My goodness, you're right! I was wondering why I couldn't make any calls, and when I checked, I found that I had paid $950 for just a battery!!! Why couldn't I see this before? You've opened my eyes. (/snark) Now, stop posting about things you have absolutely no knowledge of.
  • Battery life is only PARTIALLY related to the physical battery capacity. I have a Motorola MC67 device, it has a 4000mAh battery and it lasts about 6 hours. My Microsoft Lumia 950 has a 3400mAh battery and last 48 hours or more. It is to do with the electronics of the phone and how energy efficient the devices are.
    What is this 8 months rubbish? The battery capacity will not have dropped a significant amount in 8 months to have any noticeable difference.
    You have proven you know nothing about electronics and what the real factors are in battery life. Capacity is only one fairly small factor when it comes to it.
  • Jesus Christ, None of the batteries exploded. Less than 400 units out of more 2.1million units sold had an issue. The batteries did indeed catch fire, no disputing that. Samsung living up to thier reputation, they did the right thing and recalled it. Note 8, record sales....that's how you do it
  • Im not getting a note 8, but i think Bullhaulerz is full if BULL and thats being kind. If your going to rage at least do it with fact and not Misnomers. Today the processors are much more efficient so can last alot longer with less power. I do wish flagship phones had removable batteries , but even LG has abandoned that. Phone companies have figured out they make alot more money if you have to replace your phone every two or three years.
    As an acquaintance calls it the s8 family " the tall and skinny" I tend to agree and am going to get the HTC U11 or LG v30.
  • Ugghh ...more "exploding" from AC even though the Note 7 didn't explode. Can you guys put this to bed, or at least provide some HONEST writing?
  • The Note8 looks interesting, but I don't think it is for me. It seems to be using flagship parts that are yesterdays technology. I also am not keen on the aspect ratio with these tall skinny phones. Why can't we just have a nice 16:9 (or 9:16) ration and make the rest of the phone suit that.
    Yeah, I am whinging a little, but this looks like a stop-gap flagship to try and make people forget the Note7 debacle. A little more thought into this device and release it a bit later could have made it a great device.
    I am sorry, I know it is a nice looking device and it has good specs and all that, but to me it looks like a release just to have a release rather than a release to be a flagship for the next 2 years. @Bullhaulerz - As I said in another post. You really are showing your lack of technical knowledge, not to mention your outright slanderous claims based on - oh wait a device that is not even fully released yet with no real world statistics. Show the proof this battery "WILL NOT handle the drain". Where is your evidence? Where are your test results? What did you use to test battery life and power drain? Where are you processor and chipset power usage statistics? On the battery issue, I think Samsung did the right thing with the slightly smaller battery in order to make sure everything fits nicely to avoid the overheating. The efficiency of the 835 will more than make up for the slightly lower physical capacity.
