Kuo: iPhone 16 Pro Max Could Feature Longer Battery Life

Apple in the iPhone 16 Pro Max will use battery cells with increased energy density, according to analyst Ming-Chi Kuo, which will offer either longer battery life using the same battery size as that found in existing models, or equivalent battery life using a smaller battery.

In his latest supply chain survey, Kuo says the energy density (Wh/kg) of the battery cells in the iPhone 16 Pro Max will increase, which "has the benefit of longer battery life with the same battery size or lower battery size with the same battery life."

To avoid overheating the battery, Apple is using a stainless steel battery case for the first time as a thermal solution, according to Kuo.

Stainless steel is not as effective as aluminum in dissipating heat, but it is more robust and less susceptible to corrosion. The use of a stainless steel battery case also reduces the difficulty of removing the battery, which will help Apple comply with the European Union's requirements for mobile phone batteries' replaceability in the future.

Sunway will reportedly be a major supplier of the stainless steel battery cases. If the mass production of this new battery design goes well, Kuo believes the design will be adopted across all iPhone 17 models next year.

A rumor last June suggested that the iPhone 16 Pro models will use stacked batteries, which can result in higher capacity and a longer lifespan, but Kuo makes no mention of the technology in his survey. Apple is expected to release the upcoming iPhone 16 lineup in four months, likely around mid-September.

There are thinner phones than 15PM with 5600mAh battery. Apple just doesn't want users to have good battery life like 13 Pro Max anymore.

Hmmmmm, pay a few nickels more in materials cost to include extra battery or cut those nickels for "same great battery life" and "thinner" spin. What will modern Apple Inc choose? It's so, sooooo hard to imagine. ???

However, perhaps they should adopt the pictured shape of that part as the new phone shape:

* All those who relentlessly whine for a redesign would be able to show very clearly they own the newest phone.
* An L-shaped phone would still have the main portion slip into a normal pocket.
* Since screen size is measured diagonally, the new horizontally widened section could allow Apple to jump measurement specs from 6.XX" to maybe 9 or 10 inches while still being "pocketable": "the biggest screen we've ever had in an iPhone... and same great pocket-ability and battery life."
* Some of us could be upsold old west gun holster-like products as an accessory.
* Some of those phone holsters could offer wireless battery charging when this "gun" is holstered.
* We could practice our "quick draw" techniques for getting the phone out of the holster.
* Apple could spin the term "quick draw" in more than one way by adding a pencil slot in the "only Apple can..." holster "for only $349"
* The "The Good, the Bad & the Ugly" ringtone would probably hold the #1 spot for an extended period of time.
* Maybe make it a boomerang shape so that when you drop it- instead of hitting the ground- if curves right back to you again?
* Maybe move dynamic island thinking into the new section and call it dynamic [S]boat[/S] dock?
* Maybe bend the new section up ever so slightly and build the camera pack in there so that the overall device can lay flat on a table?

All ;)
