- A17 chip vs. A14 chip: The 5nm-based A16 chip in the iPhone 14 Pro is already up to 36% faster than the A14 chip in the iPhone 12 Pro, according to the Geekbench 6 benchmark. The iPhone 15 Pro will be equipped with the A17 chip, which is expected to be manufactured based on TSMC's latest 3nm process for even faster performance and improved power efficiency over the previous generation.
The A14 chip is fast enough for anything I do with my phone
- USB-C port: With the iPhone 15 Pro, Apple is finally expected to switch from Lightning to a USB-C port. This change will provide a more universal charging standard and allow for faster wired data transfer speeds.
Not sure why this is an improvement in and of itself. We have a mix of phones and right now every phone can charge using lightning. Until all phones are iPhone 15+ (will take a couple of years) this is not an improvement for me.
- Titanium frame: Like the Apple Watch Ultra, the iPhone 15 Pro is rumored to have a titanium frame instead of stainless steel. The back glass and display bezels are also expected to have slightly curved edges.
Not worth the upgrade for me.
- Solid-state buttons: iPhone 15 Pro models are rumored to feature solid-state volume, power, and mute buttons. Two additional Taptic Engines would provide haptic feedback to simulate the feeling of the buttons being pressed, similar to the Home button on the iPhone 7 or the trackpad on newer MacBooks.
How is this an improvement worth upgrading for?
- Dynamic Island: With the iPhone 14 Pro, Apple replaced the notch with the Dynamic Island, a pill-shaped area surrounding the Face ID sensors and front camera. The Dynamic Island displays system alerts and integrates with iOS 16's Live Activities feature to show live NBA scores, the status of an Uber ride, and more.
Dynamic Island is a gimmick. I have an iPhone 14 Pro. In 4 months I have only once found use for the Dynamic Island.
- Always On display option: With the iPhone 14 Pro, Apple introduced an always-on display option that dims the entire Lock Screen, but still shows the time and date, widgets, wallpaper, and notifications. Once you raise the iPhone, tap the screen, or press the side button, the display returns to normal brightness.
I'm not the target audience for this feature. I didn't miss it before the iPhone 14 Pro and have turned it off on my iPhone 14 Pro. Battery life is more important.
- Brighter display: The iPhone 14 Pro's display is up to 200 nits brighter indoors compared to the iPhone 12 Pro, and offers up to 2,000 nits of brightness outdoors. The increased brightness should carry over to the iPhone 15 Pro.
The brightness of the 12 Pro was already great. I have not yet noticed that it got better with the 14 Pro.
- ProMotion: Introduced on the iPhone 13 Pro, ProMotion allows for a variable refresh rate up to 120Hz for smoother appearing content and scrolling.
Apparently this is a really important thing. I have ProMotion on my 14 Pro and on my MacBook Pro. I don't have it on my Lenovo laptop. According to some, once you have seen it, you will always miss it when you don't have it. Well, I must be different. I have never been able to notice that my sons 12 Pro doesn't have ProMotion, nor that my Lenovo doesn't. So, not important for me.
- Thinner bezels: Similar to the Apple Watch Series 7 and Series 8, the iPhone 15 Pro is rumored to have even thinner bezels around the display.
Not worth upgrading for, at least for me.
- Longer battery life: Already, the iPhone 14 Pro lasts up to 23 hours for offline video playback, compared to 17 hours for the iPhone 12 Pro. With components like the A17 chip and the LiDAR Scanner expected to be more power efficient this year, the iPhone 15 Pro could have even longer battery life.
My 2 year old 12 Pro had longer battery life than my brand new 14 Pro. Battery life on my 14 Pro got better with iOS updates but still is not as good as on my 12 Pro. People around me with the 14 Pro have similar experience. Very nice that the 14 Pro works better in tests, but it doesn't hold up in my real usage.
- Numerous camera improvements: iPhone 12 Pro users upgrading to the iPhone 15 Pro will get access to a wide range of camera upgrades, including a 48-megapixel Wide lens, an upgraded front camera with autofocus, increased optical zoom, sensor-shift image stabilization, Macro mode, Cinematic mode, Action mode, ProRes video recording, Photographic Styles, and more.
This is the only thing worth something to me. It's not worth the enormous price though.
- eSIM only in U.S.: Apple removed the physical SIM card tray from all iPhone 14 models sold in the U.S., meaning the devices work with eSIMs only. The devices are still compatible with physical SIM cards in other countries.
How is this an improvement worth upgrading for?
- Increased RAM: iPhone 15 Pro models are rumored to be equipped with an increased 8GB of RAM, compared to 6GB for the iPhone 12 Pro. Increased RAM can benefit multitasking on the iPhone by allowing more apps to be open in the background simultaneously without reloading.
I see the value of this for some.
- Wi-Fi 6E: iPhone 15 Pro models are rumored to support Wi-Fi 6E, which supports the 6GHz band for faster wireless speeds, lower latency, and less signal interference compared to standard Wi-Fi 6.
In a few years, this may become important.
- Emergency SOS via Satellite: iPhone 14 models can connect to Globalstar satellites, enabling users to send text messages to emergency services when outside the range of cellular and Wi-Fi coverage. The service is free for two years after activation, and is currently available in the U.S., Canada, France, Germany, Ireland, and the U.K., with more countries to follow later this month.
This is finally something really new. If you live in one of the supported countries, and spend some time out of range of cellular networks, this may be a reason to upgrade.
- Crash Detection: New for the iPhone 14 series, Crash Detection is designed to detect severe car crashes and contact emergency services via Emergency SOS if the user does not respond. The feature is enabled by default.
I see some value for this.
- 5G improvements: iPhone 15 Pro models are expected to be equipped with Qualcomm's Snapdragon X70 modem for improved 5G performance.
I can see some value for this for some.
- 1TB option: Starting with the iPhone 13 Pro, Apple introduced a 1TB storage option.
If you are running out of space on your 12 Pro with 512 GB, this is worth a lot. I'm curious how many people need more than 512 GB on a 12 Pro. Having said this, I did run out of the 256 GB on my 12 Pro because I want to keep all pictures on my iPhone.
