The iPhone 15 could get a new battery | Apple tech | MarkMeets | Entertainment, Music, Movie, TV & London Film Premiere News

We’ve heard plenty of rumors about the iPhone 15, and the latest to catch our attention concerns a new type of battery technology that Apple may be introducing with the flagship handsets that are due to launch in September.

All four iPhone 15 models are due to come with what’s known as stacked battery design. It’s already used in electric vehicles, and – as the name suggests – means the battery components are stacked on top of each other.

That means, in theory, that the battery can be more tightly packaged and offer a higher energy density. The trade-off is that the battery runs hotter, so some careful engineering is going to be required to get this functioning properly inside an iPhone.

Assuming Apple’s engineers can get it right, we may well see battery life improvements on the iPhone 15 series. It could also mean the batteries are physically smaller, giving more room inside the phone chassis for other components (or for cooling mechanisms).

Limited introduction

We don’t get much more information about this stacked battery technology from the leak. Apparently the technology remains “limited”, so it’s possible that it’s not being fully implemented this time around while Apple works out some of the kinks.

The same source does go on to say that iPhones with 40W wired and 20W MagSafe charging have been tested (up from 20W wired and 15W MagSafe on the iPhone 14 series) – while also pointing out that these speeds might not be reached until the iPhone 16.

We should mention that, as we’ve previously reported, the Samsung Galaxy S24 Ultra is rumored to be getting the same stacked battery technology, together with a corresponding boost in the charging speeds it offers.

Another reason that the iPhone 15 handsets might offer better battery life than their predecessors is the introduction of the Apple A17 chip and the improved efficiency that it offers. We should know for sure when these phones launch later in the year.

The iPhone 15 will come in three new colors: green, light yellow and pink. The full range of colors is as follows:

Midnight
Starlight
Green
Light Yellow
Pink
Product (RED)

The new colors are italicized, and it is worth noting that light yellow is distinct from the existing strong yellow finish on the iPhone 14 lineup. If correct, the leak would mean that Apple is dropping blue, purple, and the deeper yellow finishes this year.

While opinions about Apple’s choice of colors will be subjective, the real surprise here is the extent of the changes. Apple tends to change one or two colors each year, but not three. Moreover, the decisions here are eye-opening because a market report in March claimed that blue and purple were the most popular color choices for iPhone 14 and iPhone 14 Plus buyers.

On the flip side, pink has been the most requested iPhone color for years, and rumors of a bubblegum pink finish first leaked in March though that report also claimed a new brighter blue color would be introduced. Apple has also shown its willingness to bend to customer demand this year by releasing a 15-inch MacBook Air.
