Galaxy S9's Exynos version tipped to use 'stacked' motherboard for a bigger battery

We've been hearing about "stacked" motherboards destined for iPhones for a while, and Apple is now rumored to use one in the upcoming iPhone 8, so as to free space for a larger, L-shaped battery supplied by LG. In a nutshell, those advanced SLP (Substrate Like PCB) circuit boards would stack or package the chips tighter together, making their footprint much smaller, and leaving space for other things inside a phone, like, ahem, larger batteries. That's exactly what Samsung may be doing with the Galaxy S9, tips Korean media today, referring to "industry sources". 

Allegedly, four of the ten suppliers that Samsung uses for its phones' circuit boards have the ability and capacity to produce SLP designs. Does that mean that only some Galaxy S9 units will have them? Well, the source does say that Samsung will equip the Exynos versions of the S9 with the space-saving PCB tech, though not because its suppliers don't have the capacity, but rather since the versions with Qualcomm chipsets has "technical difficulties" to use the advanced system boards, at least for now. 

Hopefully, that won't also translate in smaller battery packs for those, as the source expects that "application of SLP will quickly expand once initial introduction phase of SLP passes by." The S9 and S9+ will reportedly use the same screen sizes and chassis design of the S8/S8+, but have slimmer in-cell touch display packages, and, now, smaller logic boards, so we cross our fingers for larger batteries indeed.

Do they have to include about IPhone in Samsung article? Typical iPhonearena.

Hey, at least the iphone is the first phone with ip68 according to phonearena.:)

Don't think you read past the article title. Iphone 8 for months has been rumored to use a stacked motherboard too so it's relevant to the article

That's not the point, was it not relevent enough to be added into the title ? The author could have easily said "flagships switching to stacked Mobo's for larger batteries" instead of making it a Sammy article and using iPhones for thumbnails. It's really weird that this website does things like this to be labeled "Biased"...

It's just a phone, iPhone. No need to get riled up when PA mentions the name iPhone. It doesn't bother me in the slightest bit, it shouldn't bother you either. It is still completely relevant to the article The i8 very well could be the first smartphone to have stacked mobo, or maybe the Note 8 so

If you're not gonna consider the point he is bring to you, then dpon't answer. It just makes you look more ridicoulous. Its not just a phone. The point he made was simple. Its a Samsung article so they should have used Samsung thumbnails. Or they could have just sad, OEM's are going to use stacked PCB and Apple will have it in the iPhone 9 possibly and then a Apple cutout would have been ok. But to title it one things and have something else is stupid. Would you want to open the newspaper and the title says, bomb explodes on a street near you and you to the page of the story and it has nothign to do with the title? If so then well that says alot. If not, then you should be criticizing it here too. Either stop making lite of what many here complain about, or just don't say nothing. Because most of us hate double standard and hypocrisy.

Yes, as iPhone is still to release to release with that feature its totally irrelevant to include the iPhone in this article.

Exactly. The iPhone 8 doesn't feature a stacked logic board as it hasn't been released yet, so it isn't relevant to include it here. "The iPhone 8 may use smaller 'stacked' logic board for a larger battery, and Galaxy S9 may follow suit" Using a rumour from one handset as a reference (saying the Galaxy S9 may follow suit) for another rumoured handset... really? SMH

Aren't you actually the dumb one for visiting too often though? There clearly isn't enough "phone news" for daily articles without total guesses being made.

PA was to lazy to just use photos and drawings of the inside of an S8 or S7 vs using an iPhone for a Samsung article. Just shows who's arse their face is in all the time. PhoneArena is just a tech tabloid for Apple. Its disguised as a tech blog site. One thing I like about Android Authority is even though they are pro-Android, they give Apple fairness in their articles and its not BS like the ones here.

Slimmer in-cell touch displays and smaller motherboard... But how much battery capacity will Samsung gain from this? If, with all these design modifications, the Galaxy S9 does not pack at least 4000mAh, I'll be less than impressed.

5. mikehunta727 unregistered

Hoping that it gives at least a 400-500 mAh boost

No matter what size the Samsung battery will be, it will be bigger than most flagships as it is now.

Why are we looking at iPhone schematics for a Galaxy article... Just change the name of the website already...

Hey Android frustrated lovers: Any new phone needs to be compared with the best in the market, that is, with the iPhone.

Hey dude, question for you. When was the last time the iPhone received an award for anything? According to facts, in 2017 there were photos taken with an iPhone that won some awards and there were 12 app that received an award (none by Apple) and that's it. The last time Apple won a direct award for an iPhone that I am personally aware of, was the iPhone 4. Now, assuming I am correct, how can you claim the iPhone is the best phone, if it hasn't won any awards since then?! Now Apple has received several customer satisfaction awards, which I would say are well deserved on some level. I mean I know lots of people are satified with their iPhonee. I am satified with mine as it is a good product. But satisfied, doesn't mean being estatically happy with it, which I am not. I can eat any food and be satisfied when I am hungry. But if it was a big juicy T-Bone Steak and som scrabble eggs, it would be awesome. See where I am going? The last time Apple received an award for the iPhone itself that I could find, was J.D Power gave an award for the iPhone model of 2009. That would be the 3GS which is one of my favorites along with the 5S.

i hope the battery is actually bigger, i hate seeing manufacturers use these space saving techniques to slim phones as opposed to increase battery size

I was going to comment that the iPhone will utilize stacked components. The article beat me to it.

Stacked SoC sounds like a great way to increase heat and throttling.

I would like to see how they will pull this off in a case so small.

Yet they're second or third to have anything new and when they do its a ripoff from someone else
