Could the iPhone 8 have a large battery indeed? LG tipped to supply L-shaped cells for the 'iPhone 9' as well

A new report out of Korea claims that Apple has tasked LG Chem to be an exclusive supplier of "L-shaped" batteries for next year's iPhone 9, or whatever Apple decides to call it. While it is still early in the game to talk about a 2018 iPhone, the one that is about to be announced this fall is likely already a done deal for Apple in terms of development, and now the eyes are on the next challenge.

While Apple likes to diversify suppliers (currently sourcing batteries from four different makers), the industry source claims that LG Chem has emerged as the reliable manufacturer of choice for the tricky L-shaped design that is also rumored to be in this year's iPhone 8. Bent to the right, the piece allows for extra capacity to be had in a space vacated by using chip-stacking and other miniaturization technologies. In the case of the iPhone 8, this has reportedly allowed it to gain 30% higher capacity compared to the rectangular shape, to the tune of 2700 mAh, or just shy of the 7 Plus piece, according to JP Morgan analysts.

As per "an official in the chemical industry," who has spoken on the condition of anonymity: "LG Chem has invested hundreds of billions of won in dedicated facilities and plans to start full-scale mass production from early next year. LG Chem has [been] decided to supply all batteries for the iPhone 9 to be released in the second half of next year."

LG has been investing in its battery-making technology, hoping to capitalize on the Samsung SDI misfortune with the Note 7 power bank, and we were even invited to check out the rigorous testing procedures in their factory not long ago. It has also experimented with stacked, curved and even cable-shaped batteries for a good while, so the eventual bent piece in a future iPhone 9 may indeed be tasked exclusively to LG Chem - an "L-shape by LG," if you will. On the other hand, does this suggest that we will again have an all-screen OLED successor to this year's yet-unannounced iPhone 8?  We'll see, but there are rumors pointing at that direction as well.

I think LG always has great ideas with low budget for marketing. Sometimes they have great ideas but poor executions - like Prada, secondary screen bar, and dual cameras. We give plenty of praise to samsungs and Apple for their "firsts" - but LG is right up there but somehow manages to get lost under the radar. This battery tech is no different - great innovation, but I bet samsung or Apple be the one to implement or use it in manner that will set a trend.

Agree with you. The thing about LG's phone motherboard are weak don't know why!

They have to start paying IPhoneArena as Apple have been doing for ages.

Must you?

If they can meaningfully reduce the board size, obviously there will be more room for battery. If they can do that, that shape is not necessary for fitting a larger battery, but a design choice.

and what about... smaller board size... same battery capacity... but THINNER phone, and even bigger camera bump... I'm sure Jony Ive will love that idea, lol..

That would be all wrong decisions. But I wouldn't be surprised if you turn out to be right.

What I don't understand though; they supply others with quality parts (like display, battery), but decide to use subpar parts on their own products...

So wait. The iPhone 7 Plus as an example is bigger than the Note 7/S8+ and yet you think Apple can't fit a larger battery without changing the shape? So how does Samsung get a 3500MAH battery into the original Note 7, which is physically smaller and nearly as thin as the iPhone 7+? See if Apple didn't do stupid s**t, like remove the headphone jack so they can go thinner; then the phone would be thick enough to add a thick cell vs making it thinner and having to give the cell a stupid shape to make more fit in the same space. This is why Samsung is a better design and hardware aficionado.

I believe Samsung squeezed the battery beyond safe capacity where they forgo certain safety plates or components or just space for battery to swell a little otherwise necessary to avoid puncture - that other manufacturers did not ignore. Also iPhones now have a thicker than usual screens due to 3D Touch tech (which is an extra layer on the screen I believe). You probably don't know this, but Note 7 devices had a huge problem with batteries catching fire, that they had to recall the device twice, and finally refurbished them with smaller capacity batteries to make them safe - called Note FE. I would recommend reading up on that - calling yourself "techie" could be misunderstood by others on this forum.
