iPhone 15 Could Feature Stacked Battery Technology [Updated]

[MacRumors]

Apple's iPhone 15 lineup could feature stacked battery technology for increased energy density and prolonged lifespan, a recent rumor claims.

iPhone 15 lineup dummy models.​

According to the Twitter user "RGcloudS," the iPhone 15 lineup will feature stacked battery technology. The information came as part of an alleged leak about Samsung's Galaxy S24+ and S24 Ultra models, which are also said to utilize stacked battery technology.

A stacked battery cell uses a manufacturing technique called lamination, where the elements and separators are folded into zig-zag layers instead of being rolled up. Since there is less wasted space within the packaged cell, more active material can be included, resulting in a greater overall capacity. This allows a stacked battery to achieve higher energy density compared to a wound battery. Heat is also distributed more uniformly across the cell, rather than being concentrated in a single area, prolonging the battery's lifespan.

Electric vehicles already heavily rely on stacked batteries due to their ability to deliver high power output and rapid recharging, as well as their superior energy densities. They are also found in medical devices, aerospace and aviation, and renewable energy storage.

In addition, the Twitter user claims that they have seen signs of Apple exploring 40W wired charging and 20W charging via MagSafe, but they are unsure whether it relates to the iPhone 15 or iPhone 16 lineup. The iPhone 14 Pro Max can achieve peak wired charging speeds of up to 29W, while MagSafe only charges at 15W.

The "RGcloudS" account primarily focuses on Android leaks. The rumor has been picked up by a range of other prominent websites and news outlets, but the Twitter user's track record for Apple leaks is unclear, so it should be taken with a pinch of salt at the current time.

Update: "RGcloudS" now claims that Apple's stacked battery technology is instead destined for the iPhone 16 lineup, alongside 40W wired charging and 20W charging via MagSafe. Apple purportedly wishes to introduce larger image sensors and stacked battery technology simultaneously.

I'm always down for a bigger battery capacity. Same for faster charging. Let's goooo!

Props to the guy for breaking his thumb to get the shot of four iPhones held in one hand.

 

[MacProFCP]

Does this add significant cost? I'm curious why, if this is so good, Apple waited years to implement it.

I assume this will add weight due to the batteries being more densely compacted.

 

[madmin]

Oh man I've been rolling up today and now I'm so stacked to hear about this folded iPhone with the zig-zag layers

*40W wired charging requires MFI USB-C cable.

Is this going to be one of the years where iPhones have good batteries? I'm so hyped

(I still have flashbacks to when 2019's iPhone 11 had great battery life and then 2020's iPhone 12... didn't.)

 

[iamgalt]

I really hope this is true and makes it onto the 15. I'd hate to buy a new phone, only to have the battery get, what sounds like a significant upgrade on the next model.

and in EU that will need to be user replaceable

 

[Cromulent]

Battery life is the most important thing for me, so this sounds great!

 

[Aurizen]

I would absolutely love this! Better battery technology would be the best especially if this has the battery degrade less over time.

 

[contacos]

and in EU that will need to be user replaceable

I think that part only goes into effect in 2027?

and in EU that will need to be user replaceable

They are user replaceable now. Apple offers the kit, shipped wherever you like, to do it yourself.

at this point...we have great battery life...at this point lightness per battery capacity ratio is more important

 

[boswald]

Finally, new battery tech! Really excited for this news. Can’t wait to see where we go from here.

There are constant tradeoffs with all these devices. Apple has always been trying to balance it all out. The new OS with dynamic widgets and other new features will require more background processes therefore use more power and therefore degrade the battery more quickly. This battery tech will hopefully balance that out but will add more weight. The new titanium chassis will hopefully balance that out as well. Apple is not directly trying to improve any one area of the iPhone. They are trying to rebalance their device with strategic tradeoffs.

No we do not have "great battery life." Iphone battery (especially on IOS 16) is trash.

 

[TheYayAreaLiving 🎗️]

This is great news! Glad, Apple is finally taking the battery life for the iPhone seriously! Couldn't be much happier.

Or they could put a legit-sized battery in their devices. Apple needs to quit skimping on battery while claiming "efficiency" when they destroy it a few months in with their software updates.

Is it? I go to bed with 20-40% on my 13 Pro daily. I've see zero difference between ios 15 and ios 16.

 

[Mitthrawnuruodo]

Coming from an 11 Pro (with reasonable battery health), and planning to replace that with a 15 Pro this fall, this would be very welcome.

 

[Freaky Spock]

Stacked and dummy thick 🥵

Super interesting this will allow for either smaller batteries or faster processors most likely retaining the “same all day battery life”.

 

[CarAnalogy]

Can the iPhone 15 feature split screen multitasking? Nope.

I’ve largely given up using my phone for work and just whip out the laptop for everything. Definitely don’t bother using the iPad anymore. Depends on what you’re using it for, but a phone screen just isn’t meant for high productivity work in my opinion. Apple wants you to buy at least one of each class of their devices. Quickly jot things down on the phone, bust out the larger screen devices for work.

All of which makes me wish Apple would focus more on making the iPhone a good phone, and really putting some work into the Phone app.

Which really isn't all day in any real-world usage of the device. Wish they would quit cutting back on the batteries and trying to claim the software will keep it running when it doesn't.
