Apples iPhone 15 Pro is close to solving one of our only major complaints about the iPhone 14 Pro and we think it could do so in a big way with the iPhone 15 Pro’s battery life exceeding that of all the Pros who preceded him.
Now, to be clear, we’re not talking about beating the iPhone 15 Pro Max or even the iPhone 14 Pro Maxbut there are two key new updates expected to come to the iPhone 15 Pro in 2023 that should propel its battery life to new heights.
Stacking the deck
The first upgrade is at one level the most obvious: a bigger battery. This comes from a leak in early July which indicated that iPhone 15 Pro would get about 12% larger battery than its predecessor at 3,650 mAh.
It’s not the smartest thing, it’s how Apple managed to fit in that larger battery without dramatically increasing the size of the phone, which earns them a piece of the cap. A second leak in July confirmed the larger battery and revealed a new stacked battery cell for the iPhone 15. While this is new technology for the iPhone, it’s not new for Apple, the company used this same concept to squeeze as much battery as possible into the previous generation MacBook Air.
Not only should the stacked battery cells allow Apple to fit a larger battery in the same space, but they should also provide superior longevity. For someone whose iPhone 15 Pro is already down to 90% capacity, this seems like a game changer.
Slim to win
No, I’m not talking about the iPhone itself getting thinner, but the A17 Bionic chipset inside will be the first to be built using a 3nm process, as it looks like Apple cornered the market with TSMC’s first series of 3nm chips.
What does this have to do with battery life? The denser a chip, the faster data can pass through it, because the distance needed to travel between points is reduced. Although we see improvements in efficiency with each generation of chips, the major advancements come when they can scale down to a smaller process. This move from 4nm to 3nm is rumored to offer 35% greater energy efficiency.
The iPhone 14 Pro barely passed the 10 hour mark in our Laptop Mag battery test, the screen turning off at 10 hours and 13 minutes. It’s not a terrible result, but the iPhone 13 Pro is almost 2 hours short on the same test. Plus, I’m not the only one to see a massive reduction in my overall battery capacity over the year, meaning it’s nowhere near 10 hours now.
So while battery life wasn’t a deal breaker on the iPhone 14 Pro, it was the biggest drawback that I called attention to every time someone asked me if I would recommend it. Typically, I pointed them to the iPhone 14 Pro Max if they were OK with the size, as it didn’t suffer from any of these issues.
Whether Apple knew the iPhone 14 Pro’s battery life was going to be an issue or not, it appears the solution is waiting in the wings for 2023, as the larger battery and more efficient 3nm process will certainly catapult iPhone 15 Pro battery life. (and the iPhone 15 Pro Max) reach new heights in 2023. I wouldn’t be shocked to see the iPhone 15 Pro arrive around 12:30 and the iPhone 15 Pro Max could be the first flagship phone to reach 2 hours and 30 minutes. hours of battery life, which would cement it at the top of our phones with the best battery life.
The good news is that we should only have a little over a month before we find out, as Apple’s September event is going like clockwork, so we expect to see the iPhone15 And iPhone 15 Pro the models will debut in the middle of next month.
