The iPhone 15 series is here, and by all accounts Apple has made a huge number of improvements to the lineup. However, that does not mean that the iPhone 15 is perfect, and there are many upgrades that we would have liked to have seen but did not. In other words, the pressure is on for the iPhone 16 to fill the void.

We're still a year away from actually seeing the iPhone 16, but that doesn't mean we don't have anything to talk about yet. We're already starting to hear rumors about what changes could be made to the iPhone, and there are plenty of ways we'd like to see Apple improve the iPhone experience next year.

So here are nine things we'd like to see in the iPhone 16.

The biggest disappointment of the iPhone 15 and iPhone 15 Plus was the lack of a display upgrade, while the iPhone 15 Pro and Pro Max can enjoy the benefits of ProMotion's adaptive 120Hz refresh rate.

The iPhone 16 should eventually increase the refresh rate, or at least give Apple a screen that can reach 90Hz. But given that it's not that impressive, a push toward 120Hz across the entire lineup would better serve Apple; let's hope the Always-On display can make the leap as well.

Since Apple introduced Face ID and the notch in 2017, it has gradually whittled away the screen space these sensors occupy. The slimming of the notch and the disappearance of the sensors all culminated in the current Dynamic Island design. Now it is time for Apple to take it a step further.

We've already heard rumors that Apple may push all Face ID sensors under the display in the iPhone 16 or iPhone 17, and we're all for it. If Apple can do this, it would mean one less notch in the iPhone display and one more hole for the selfie camera. Less notch means more room for other things on top of the screen.

Perhaps one day Apple will be able to hide the selfie camera under the display as well. It has already been done on other phones, but the results are often unimpressive. However, after a few years, someone may be able to improve the quality of hidden cameras.

The iPhone 15 Pro may lack new camera hardware, but the iPhone 15 Pro Max's tetra prism lens is a big step forward for Apple photography. However, there's no denying that next year could be even better. For starters, we would like to see Apple add a tetraprism lens to the iPhone 16 Pro to enhance its telephoto capabilities beyond the mere 3x magnification currently available.

There is speculation as to why the iPhone was not upgraded, ranging from production issues to the fact that the iPhone was too small to fit. Either way, it's something Apple can work on fixing for next year. Especially if these rumors of a larger iPhone 16 Pro end up being true.

But that's not all: the 5x optical zoom on the iPhone 15 Pro Max is basically fine now, but there's no harm in offering more optical zoom on the iPhone 16 Pro Max, or whatever it will be called Ultra. Given that Samsung's Galaxy S23 Ultra offers 10x optical zoom and the S24 Ultra is rumored to have a hybrid lens with variable optical magnification, Apple needs to step up if it wants to avoid being left far behind.

The iPhone 15 made history by switching to USB-C, but the results were... . was disappointing, to say the least. However, the iPhone 16 gives Apple the opportunity to fix that and ensure better data transfer speeds throughout the lineup. And if Apple really wants to impress everyone, adding Thunderbolt to the Pro model would be the way to do it.

The good news is that the former is quite likely. Since the iPhone 15 has last year's A16 Bionic, it is speculated that it is limited by the A16 USB controller chip designed for USB 2.0 Lightning cables. If so, moving to A17, whether Bionic or Pro, should allow non-Pro iPhone 16 models to send and receive data a bit faster, along with all the other benefits of USB 3.0.

As for the Pro, we will see iPhones with the A18 chipset next year. Needless to say, Thunderbolt 3 is much better than regular USB 3 (or 3.1 and 3.2), with better accessory support and twice the data transfer speed. Therefore, it could end up being a relatively simple upgrade.

Unfortunately, the switch to USB-C has not improved the iPhone 15's charging performance much, limiting it to 20W-27W of power; a jump to 30W would definitely be a win, but we'd like to see the rumored 35W charging speed materialize.

As for the battery itself, Apple is doing a very good job: the iPhone 15 Plus and Pro Max lasted over 14 hours in our testing regime, proving that the iPhone 15 and 15 Pro are clearly superior to their iPhone 14 counterparts. So we'd like to see more of this, and hopefully all four iPhone models will achieve battery life beyond the 12-hour mark, which shouldn't be too much of a challenge given the A17's improved efficiency and the potential for more battery capacity.

The action button is one of the more interesting features on the iPhone 15 Pro, but its practical use is rather limited. As we have found with this phone, it is limited to one action at any given time. The fact that there are so many things that can be paired to the button is great, but it would be even better if one could pair multiple things to the button.

Apple does not need to make the process so complicated either. All it needs is to allow multiple taps to be used to activate specific actions. In other words, a single tap to turn the flashlight on and off, and a double tap to open the camera app. There are limits to this, and anything beyond three taps would be a bit extreme. However, more functionality is never too much to ask for.

Over time, we will need more storage. Apps will get bigger, videos and photos will get more detailed, and system software will treat storage like a mouse treats an all-you-can-eat cheese buffet. 128 GB of storage is the limit, especially if you don't have access to the cloud.

iPhone 16 Solution. Set the minimum level of storage to 256GB, as Apple did with the iPhone 15 Pro Max. That would be perfect for those who can't bring themselves to pay $10 per month for an iCloud subscription and need a huge amount of space.

Apple offers the best mobile chipset, but its lead may feel a bit tenuous at best; Android chipsets are doing their best to catch up, and the Snapdragon 8 Gen 2 for Galaxy is doing well in graphics benchmarking and The A17 Pro is once again dominating the competition in benchmark tests, but more chips will be coming in the next few months.

It is important that Apple continues to push the limits of what mobile chips can do. Because once they catch their breath, Qualcomm and others will only gradually catch up. This will be especially true once the rest of the mobile industry has access to 3nm chips that offer better efficiency and performance.

Where these chips will go is another question entirely, but that's for the engineers to figure out; I hope the iPhone 16's A17 chipset is not a mere copy of the A17 Pro.

It's an obvious question when you think about it, but given the amount of rumors about a possible price increase for the iPhone 15, it seems like it's only a matter of time before iPhone prices go up again. as a result of eliminating the 128GB model, which would raise the minimum price like the iPhone 15 Pro Max We are not talking about a price increase, but a proper price increase.

The iPhone is expensive enough as it is, and no one likes having to pay a higher price for a new phone. iPhones will still sell in large numbers, but the consequences of having to pay more may force people to hold onto their phones longer. They may be forced to hold on to their phones longer. In other words, the best thing Apple can do is hold off on it for as long as it can.
