The iPhone 8 has been a tried-and-true performer since Apple first introduced the phone in 2017. Available in both a standard and Plus-sized version, the iPhone 8 proved popular enough to remain a part of Apple's iPhone lineup until the introduction of the iPhone SE earlier this year. (And even that phone adopted the iPhone 8's design.)
But all good things must come to an end, and if you bought the iPhone 8 when it first came out, there's a good chance your phone is starting to show its age. The arrival of the iPhone 12 and its different editions gives you the opportunity to look at upgrading your iPhone.

iPhone 12 vs. iPhone 8 price and availability
The same year the iPhone 8 came out, Apple released the iPhone X, which signaled the dawn of $999 flagship phones. But the iPhone 8 held the line on pricing, starting at $699. With a larger screen and two cameras, the iPhone 8 Plus cost $100 more. Prices have since dropped, with the iPhone 8 costing $400 or less at outlets that still offer it.
Like the iPhone 8 before it, the iPhone 12 and iPhone 12 mini avoid that $999 price. Instead, the iPhone 12 mini debuts at $699 — the same price that Apple charged for the iPhone 8 back in the day. You can get an iPhone 12 for $799. (Note that those prices are for carrier-tied versions of the two iPhone models. An unlocked version costs $30 extra.)
The iPhone 12 is now available for pre-order in advance of its Oct. 23 launch, and we're monitoring the best iPhone 12 deals. You'll have to wait until Nov. 13 for the iPhone 12 mini to arrive; pre-orders start a week earlier.
iPhone 12 vs. iPhone 8 design
The iPhone 12 mini features a bigger screen than the iPhone 8 — 5.4 inches versus 4.8 inches. Yet Apple's newer phone is both shorter and slimmer than the iPhone 8.
How did Apple pull that off? The big bezels at the top of the iPhone 8's display are gone, as is the home button housed in that bottom bezel. Instead, the iPhone 12 mini, like the iPhone 12, has adopted the design Apple introduced with the iPhone X — a notch at the top of the display to house the TrueDepth camera, but otherwise minimal bezels surrounding the front display.
Likewise, the iPhone 12 is more compact than the iPhone 8 Plus, even with a screen that adds an additional 0.4 inches.
Those screens on the iPhone 12 are fairly durable, as Apple teamed up with Corning to create a Ceramic Shield screen. That makes the iPhone 12 and iPhone 12 mini four times more likely to survive a drop without any damage. The IP68 water resistance rating on the iPhone 12 models allows Apple's new phones to survive a dip in up to 6 meters of water; the iPhone 8 models could only endure 1 meter.
iPhone 12 vs. iPhone 8 display
The iPhone 8 is a relic of the days when Apple used LCD panels for its smartphone displays. That began to change with the iPhone X's introduction that same year, and today, the entire lineup of flagship iPhones features OLED screens. That includes the iPhone 12 and iPhone 12 mini, both of which sport Apple's Super Retina XDR display.
The switch from LCD to OLED means sharper colors and truer blacks on the iPhone 12. The contrast ratio is 2 million:1 on the iPhone 12 versus 1,300:1 on the iPhone 8. The iPhone 12 displays 114.5% of the sRGB color spectrum, about what the iPhone 8 captured (119.6%). The iPhone 12 renders colors much accurately than the iPhone 8 with a Delta-E rating of 0.29 versus 0.89. (The closer to zero, the better.) The iPhone 8 Plus' display is slightly more accurate, though, going by its 0.25 Delta-E rating.
iPhone 12 vs. iPhone 8 camera
The photos produced by the iPhone 12 should be a big leap forward from the iPhone 8, and not just because the older phone ships with a single 12-megapixel camera. The iPhone 8 Plus doubles things up with a second 12MP lens and a 2x optical zoom.
Both the iPhone 12 and iPhone 12 mini feature two lenses as well — a 12MP wide and 12MP ultrawide shooter. The apertures are bigger on the iPhone 12 cameras than they were with the iPhone 8, to let in more light.
But the camera story isn't just about hardware. Apple's photo processing powers have gotten a lot more sophisticated in the three years since the iPhone 8 came out. The latest iPhones support features like Night Mode on all their cameras and Deep Fusion for emphasizing more details and textures in photos. A new version of Apple's Smart HDR feature helps the iPhone 12 adjust white balance, saturation and contrast on the fly, so shots will look good even in challenging lighting. And the new phones are capable of capturing HDR video with Dolby Vision.
Put it another way: The iPhone 8 Plus may have as many rear cameras as the iPhone 12 and iPhone 12 mini, but the machine learning-powered software on the latest iPhones lets you do so much more. We were pretty impressed with the performance of the iPhone 12 cameras, and you'll certainly notice the big step up if you upgrade from an iPhone 8 or 8 Plus.
iPhone 12 vs. iPhone 8 performance
Here's where iPhone 8 upgraders will likely see the biggest leap, though. Both the iPhone 8 and iPhone 8 Plus used the best Apple silicon of their day — an A11 Bionic chip. That processor was more than able to hold its own against the best chipset for Android phones at the time, the Snapdragon 835.
But Apple hasn't stood still in the last three years, introducing subsequently more powerful processors with each iPhone release. We're up to the A14 Bionic with the iPhone 12 and iPhone 12 mini, and to hear Apple tell it, that processor will outperform last year's silicon by some margin, let alone chips that came out in 2017.
We ran Geekbench 5 on the iPhone 12, and got single- and multicore scores of 1,593 and 3,859, respectively. We don't have an iPhone 8 handy on which to run Geekbench 5, but the iPhone 12 outscored the iPhone 11 Pro Max (1,334 and 3,517 on single- and multicore tests), and since that's a relatively recently A13 Bionic chip, we assume the A11-powered iPhone 8 would eat the iPhone 12's dust.
Apple hasn't stepped up one aspect of its smartphones. Storage is still relatively minimal, with base models of the iPhone 12 and 12 mini continuing to offer the same 64GB of capacity featured on the iPhone 8. At least you've got more storage options now, with 128GB and 256GB models of the latest iPhones. (The iPhone 8 had a single 256GB upgrade.)
One other aspect separates the iPhone 12 models from the iPhone 8 — the new iPhone can connect to 5G networks. Stick with an iPhone 8, and you're stuck on LTE.
That may not sound like too much of a sacrifice now, with 5G networks still in their early stages. But because the iPhone 12 and iPhone 12 Pro work with multiple flavors of 5G, Apple's new phones should be relatively future-proof as 5G becomes more widespread and consistently faster. (For now, you can look up when 5G is coming to your area.)
iPhone 12 vs. iPhone 8 battery and charging
It's hard to compare battery life between older and newer iPhones, in part because Apple never reveals the size of the batteries it inserts in its phones. Teardowns suggest the iPhone 8 had an 1,821 mAh power pack while the iPhone 8 Plus used a 2,675 mAh battery.
When we ran both phones through our battery test in 2017, the iPhone 8 turned in a slightly above-average result, while the iPhone 8 Plus held out for 11 hours. That would be good enough for either one to still land on our best phone battery life list, which we limit to phones released in the last year-and-a-half.
Strictly speaking, the iPhone 12 doesn't measure up, lasting 8 hours and 25 minutes on a test the iPhone 8 and 8 Plus both aced. We don't imagine the iPhone 12 mini will fare better, as its compact size restricts just how big a battery Apple can place inside that phone.
The culprit for the iPhone 12's disappointing battery result? Besides that 6.1-inch OLED panel, we'd point the finger at 5G. When we turned off 5G and ran the same test over LTE, the iPhone 12 held out for 10 hours and 23 minutes — nearly two hours better.
The iPhone 8 was the first Apple phone to support wireless charging, and that's continuing with the iPhone 12. But Apple's phones have now added support for MagSafe wireless charging, in which magnet-equipped chargers attach to the back of the phone for a more reliable charge. More importantly, MagSafe supports 15W wireless charging speeds, faster than the 7.5W supported through conventional charging pads.
iPhone 12 vs. iPhone 8 software and special features
The iPhone 12 vs. iPhone 8 match-up is pretty even here. While the iPhone 12 ships with iOS 14 pre-installed, iPhone 8 users have been able to upgrade to that version of Apple's software since it came out in September. And iOS 14 introduces a number of new features such as home-screen widgets, better app organization, and improvements to Maps, Messages and Reminders that can make an older iPhone feel like new.
If the last iPhone you bought was the iPhone 8, you're probably used to getting wired headphones and a charger in the box. That doesn't happen with the iPhone 12, though, as Apple is ditching those accessories in the name of more environmentally friendly packaging and less e-waste. (Getting people to pony up for their own accessories probably didn't dissuade Apple from making that move.)
iPhone 12 vs. iPhone 8 outlook
You'd expect a phone packing in three years of design changes, hardware improvements and software enhancements to be a significant upgrade over its predecessor, and that's what Apple has delivered with the iPhone 12 vs. the iPhone 8.
We'll need to test the iPhone 12 mini when it ships next month to provide the ultimate verdict, but we've seen enough of the iPhone 12 to know it's one of the best iPhones. If you're holding onto an iPhone 8, there's no better time to upgrade than right now.
