The iPhone 13 should be unveiled at Apple's event on September 14, and according to the latest rumors, there will be plenty of people wondering if the new iPhone is worth the upgrade.

We can't answer the latter question until we do our own iPhone 13 review, but we have plenty of reports and leaks that have combined to provide a pretty clear picture of what to expect from the new iPhone 13 lineup.

In fact, there are some pretty last-minute rumors, including the possibility of satellite connectivity. And there is talk that the iPhone 13 could be more expensive than this one due to higher production costs.

Here are the 7 major features and upgrades we've heard so far for the iPhone 13, excluding the obvious ones like a faster A15 Bionic chip.

Here's the iPhone 13 leak: according to Apple analyst Ming-Chi Kuo, the iPhone 13 will feature satellite communications via a custom version of the Qualcomm X60 modem and possible collaboration with Globalstar. Once enabled, this feature will allow users to make calls and send texts without the need for a cellular connection. This would be extremely useful and could even save the lives of people who are out of range of traditional cell towers.

While satellite connectivity sounds appealing, it is unclear how extensive this support will be; according to Bloomberg, Apple plans to use the iPhone's satellite connectivity feature as part of a plan to enable an emergency alert system that can send messages to contacts and emergency services when cellular connectivity is unavailable may be planning to use it as part of a plan to enable the system.

According to follow-up reports, the iPhone 13's satellite communications may be limited to certain markets and areas without cellular coverage. However, it is still a nice feature.

While we are disappointed that Apple reportedly will not offer in-screen Touch ID on the iPhone 13, there may be another solution: according to Jon Prosser of FrontPageTech, Apple is testing Touch ID that can work with a mask hardware improvements it is testing. While there is no guarantee that this technology will be available in time for the iPhone 13 launch, it is encouraging that Apple is at least working on a solution, as the CDC recommends that even vaccinated individuals continue to wear masks indoors in most areas of the U.S.

For several months now, we have have seen rumors that the iPhone 13 will eventually feature a 120Hz display. It is also expected that Apple will optimize many of the games on Apple Arcade to take advantage of the higher refresh rate.

The bad news is that this upgrade is reportedly limited to the iPhone 13 Pro and iPhone 13 Pro Max, with the name ProMotion being used to describe this feature. We really hope this rumor isn't true, as the best Android phones under $500 offer fast refresh displays, but we'll have to see. Maybe the iPhone 13 will go up to 120Hz, but the ProMotion panel on the Pro model could shrink further to save battery life.

The iPhone 13 camera is expected to receive a number of hardware upgrades, including sensor-shift image stabilization on all four models and an improved ultra-wide angle lens with autofocus on the iPhone 13 Pro model. It is also possible that the optical zoom lens will fold out on the iPhone 13 Pro and/or Pro Max.

However, I am more excited about the rumored computational photography upgrades in the new iPhone, including portrait mode video and astrophotography. Portrait mode video is not new, as it is available on flagships like the Galaxy S21 Ultra, but the iPhone generally takes better portraits than Samsung phones.

Astrophotography may be an even bigger problem, as the iPhone has struggled to capture the night sky for years. It is extremely difficult to get a good picture of the moon, so it would be nice to see more attention paid to this particular nighttime feature.

To manage expectations, I should mention that this could be yet another iPhone 13 feature, limited to the Pro model because it requires a 120Hz display for best functionality. Regardless, it is worth noting that the iPhone 13 series may finally offer an always-on display. This display is said to allow users to check the time, battery status, and possibly notifications without having to turn the screen on completely. This would presumably save battery life.

Depending on how Apple implements the always-on display on the iPhone 13, it could simply consume less power and show everything the regular lock screen does, but at a lower brightness. Alternatively, Apple could go a step further than its competitors and offer widgets in always-on display mode. However, it will be necessary to see how Apple deploys a feature that has long been available on Galaxy phones.

Yes, while I would love to see the iPhone notch go away altogether, it is nice to know that Apple may reduce the notch on the iPhone 13 by up to 25%. This will reportedly be accomplished with a more compact TrueDepth sensor and the possibility that Apple will move the speaker away from the notch area and further up the phone.

The notch has been an eyesore since the iPhone X launched in 2017, but I believe it was worth the trade-off in terms of how well Touch ID works. That's because facial recognition on phones like the Galaxy Z Fold 3 is slow and shaky at best. Still, I'm glad we can get a little more screen real estate back, because it's a great way to get more screen real estate for our phones.

Battery life on the iPhone 12 has not impressed us, with the exception of the iPhone 12 Pro Max. This should result in longer endurance.

For example, the iPhone 13 mini is said to have a 2,406 mAh battery, up from 2,227 mAh in the 12 mini, while the regular iPhone 13 goes from 2,815 mAh to 3,095 mAh. iPhone 13 Pro is similar, with the same 6.1-inch display, which is expected to be the same size. Finally, the iPhone 13 Pro Max is said to jump from 3,687 mAh to 4,352 mAh. Therefore, we expect at least the Pro Max to make our best smartphone battery life list.
