Will the iPhone 15 get a wireless charging upgrade? A look at the rumored new feature and other reports we've heard so far.

Even with the announcement of Apple's new augmented reality headset, anticipation (and rumors) haven't dampened for the fall release of Apple's next iPhone, presumably called the iPhone 15. Those rumors, plus last year's EU ruling mandating USB-C charging on phones sold within Europe, might mean a number of departures from Apple's traditional design. Will the iPhone 15 have a USB-C port? Will Apple increase iPhone prices in 2023? Will it even be called the "iPhone 15"? No one outside of Apple knows for sure, but these reports will certainly feed our curiosity until Apple throws the next iPhone event (probably in September). Here are some of the biggest and most credible rumors we've seen so far, to paint a picture of what we may see from the iPhone 15.

iPhone 15: Wireless charging upgrade
According to a May report by ChargerLab, a power specialist website with a steady track record, all iPhone 15 models will support 15W wireless charging using the Qi2 open standard. If this turns out to be true, it'll mean the iPhone 15 could open up a whole new world of wireless charging devices that can replenish the device at its full speed. Apple had previously limited open wireless charging standards to 7.5W, leaving the full 15W charge speed for Apple MagSafe licensed accessories.

iPhone 15 camera: Periscope-style telephoto lens arrives
Noted Apple observer Ming-Chi Kuo, an analyst with TF International Securities, forecasts that the iPhone 15 Pro Max will receive a periscope-style telephoto lens. This sort of telephoto lens allows for higher optical zoom levels, with Kuo forecasting a 6x optical zoom could arrive in the iPhone 15 Pro Max. The optical zoom on the iPhone 14 Pro Max is limited to 3x, which lags rivals such as the Samsung Galaxy S22 Ultra's 10x optical zoom. This rumor was recently bolstered by well-known leak source and Twitter user Unknownz21, who stated that the Pro Max model will come with the special lens.

iPhone 15 design: Hello USB-C, goodbye Lightning
This one has been in the rumor mill for years now, but in 2023 the switch from a Lightning Port to a USB-C port could finally happen. That's possibly due to pressure from the European Union, which has been pushing for a common charging standard for years. In 2022, the bloc managed to pass legislation requiring Apple to equip its iPhones with USB-C ports by 2024 if it wants to sell them in the EU.

The question is whether Apple will switch all iPhone models to USB-C or just those sold in the EU. Apple already modifies iPhone models regionally, as it has done with the iPhone 14: The US version has an electronic SIM, while other variants retain the SIM slot. However, there are good reasons to move all iPhones to USB-C moving forward, according to Avi Greengart, analyst at Techsponential.

"There are larger ecosystem, security, and accessory considerations with the power/data connector, so I think it is more likely that Apple moves all iPhones [globally] to USB-C in the iPhone 16 timeframe to comply with European regulations," he told CNET in an email.

iPhone 15 design: Dynamic Island expands to all models
Apple is likely to continue selling four iPhone models with the iPhone 15 lineup. Rumors point to a generally similar design across the board, except that the iPhone 14 Pro's shape-shifting cutout, known as Dynamic Island, is set to make its way across all models.

That rumor comes from display analyst Ross Young, who also said in a September tweet that he's not expecting base iPhone 15 models to have a higher refresh rate like Apple's Pro iPhones because the supply chain can't support it.

iPhone 15: Solid-state buttons come to pro iPhone 15 models
Yet another Kuo prediction has been making the rounds, but this time the analyst expects Apple to differentiate further between its base and Pro models in the coming years. One way he's expecting that to happen is by giving the iPhone 15 Pro models solid-state volume and power buttons instead of the standard keys present on today's devices, he wrote in a tweet in October.

The solid-state buttons, which Kuo says will be similar to the home button found on the iPhone SE and iPhone 7, mimic the tactile feel of pressing a button with the help of haptic feedback. The apparent advantage of this type of button is that it also protects against water getting in.

iPhone 15 Power: Increased RAM for pro models
According to Taiwanese research firm TrendForce, Pro models of the iPhone 15 lineup will get a bump up in RAM to 8GB from 6GB to complement the anticipated A17 Bionic chipset. Base models will continue to receive 6GB RAM, according to TrendForce. This rumor is also apparently backed up by a research report from analyst Jeff Pu of Haitong International Securities, according to a MacRumors article, which referenced Pu's report.
