(CNN) —  

The iPhone 12 isn’t exactly a complete overhaul of the iPhone 11, but does bring few, albeit somewhat minute, improvements. Namely, the iPhone 12 sports an OLED display, boasts a faster processor, features a few camera improvements and, of course, has the long-talked-about 5G support.

Those adjustments, though, bumped up the price tag. The iPhone 11 brought value at just $699 for a flagship smartphone; the iPhone 12 starts at $799.

If you bought an iPhone 11 last year, though, are the features above worth the upgrade? Or does this make better sense if you have an iPhone 8, XR or XS?

Well, we’ve been using the iPhone 12 for the past six days — shooting photos, performing our daily use cases and testing 5G. Apples to apples (sorry, but pun definitely intended) the performance improvements are a bit hard to see directly in comparison to the 11. Photo improvements are visible in low-light shots, for instance. And processing speeds are a bit speedier.

But let’s get down to the nitty gritty of the iPhone 12 and if the improvements are a reason to upgrade.

There’s no wall-charger in the box

Before diving into what the iPhone 12 does bring, let’s first cover a glaring omission: There’s no wall plug included in the box.

Apple opted not to include the charger as the company works to reduce emissions. Their thought: You already have a charger at home, so why send another?

That’s a bit counter intuitive, though. Apple does include a USB-C to Lightning cord. But to use the cord you’ll need to buy a USB-C wall plug if you’re upgrading from a previous iPhone. Apple sells a 20-watt USB-C plug, which can fast-charge your iPhone 12, for $19.99; Anker makes a nano option that is super tiny; and there are other companies, like Belkin, in the mix of third-party companies offering chargers.

If you do opt to stick with the older 5-watt plug, don’t expect fast charging speeds, especially the new feature that can charge 50% of the battery in 30 minutes. Instead, you’ll get an old-fashioned trickle charge that, after 30 minutes, will only provide a small boost. And it will require full overnight charge to get from 0% to 100%.

That’s why, though Apple’s focus on sustainability is laudable, we still suggest you pick up one of the third-party wall plugs that support USB-C charging and meet the 20-watt suggestion.

Let’s talk about 5G

Over the past six days, we haven’t just been testing the iPhone 12, but we’ve been testing 5G in and around New York and New Jersey. And we have three big takeaways:

First: If you’re in an area that supports 5G Ultra-Wide Band (aka mmWave), you will see faster speeds, but need to be in direct line of sight with a cell tower or at least very close to it. In our testing on both AT&T and Verizon 5G Ultra Wide Band being inside a car, walking too many paces to the left — or even to the other side of the street — resulted in losing signal. It wasn’t every time, but enough to mention it. When we did get the signal on Verizon, we hit a maximum of 2,200Mbps down which is way faster than our gigabit connection. We were able to easily download a double album in just under a minute and streams happened almost instantaneously. AT&T didn’t present such crazy speeds, but we were able to hit 300-400Mbps down. Neither carrier produced widely fast upload speeds and it seems the technology is taking longer to develop on that front.

Second: Nationwide 5G from any of the carriers is not the super fast speeds that you’ve been teased with. It’s the lower portion of the wireless spectrum, Sub6 Ghz, which is both easier to rollout and provides more capacity. But it doesn’t deliver wildly fast speeds and it is the 5G you likely have in your location. In our testing, AT&T, T-Mobile and Verizon all produced speeds somewhere in between 100Mbps and 200Mbps down. Uploads were pretty close to what we’d expect to see on LTE.

Third: For some people, you’ll be able to take advantage of 5G on the iPhone 12 right now. For many, though, opting for 5G compatibility is future proofing your device, as you won’t be able to connect right away (or, stay connected).

In short: The addition of 5G support means you won’t need to go out and buy a new iPhone next year or whenever 5G becomes truly nationwide. So, if you opt to upgrade now, you’ll have a phone with great cameras and strong performance along with the latest networking standards for years to come.

Dual cameras and Night Mode on every lens

Over the years, the iPhone has become known as a dependable shooter. And Apple really isn’t messing with its tried and true formula this year, focusing on cameras and software that come together for clear, realistic images.

The iPhone 12 features a 12-megapixel wide lens that’s built with a new seven-element lens. The aperture is improved to ƒ/1.6 from ƒ/1.8 on iPhone 11, which Apple says improves low-light performance by 27%. A lower aperture lets more light into the lens; more light means a clearer picture. This wide lens is paired with a 12-megapixel ultrawide that boasts a 120-degree field of view. The TrueDepth Sensor on the front houses a 12-megapixel camera for selfies and video calls.

All of this tech across hardware and software come together to make the iPhone 12 a really dependable content capturer. Sure, the iPhone 12 lacks the telephoto lens and LiDAR sensor found on the 12 Pro and 12 Pro Max, but for many, they won’t miss those features.

For starters, we found that both of these lenses capture a large amount of detail and don’t mess around when it comes to colors — namely in the realm of saturation and hues. As with iPhone models before the 12, this device captures with a sense of realism. Saturation doesn’t get turned up to 10 and the colors don’t skew one way.

Take this photo from a pumpkin patch, you can see the natural orange of the pumpkins presented clearly, even capturing the dirt particles splattered on the tops and sides. It’s a pretty bright shot, but the lenses can handle shadows and brights together in the same frame. Even the red of the apple is clear in the shadows below the front pumpkin; same for the green grass with some bright spots via sun rays in a smattering.

This level of detail is thanks to Deep Fusion, a proprietary technology from Apple that uses the Neural Engine found in the A14 Bionic chip. It works to improve texture details in shots, allowing you to zoom in and see details rather than pixelation. You can see several more shots from both the wide and ultra-wide lens on the iPhone 12 below.

And when the lights go out, you don’t need to opt for a flash, or worse — put the camera away. Apple finally joined the low light-enhancing party last year with Night Mode with the iPhone 11. With the iPhone 12, Night Mode — Apple’s shooting mode for low-light situations — expands beyond just the main wide-angle lens to both the ultra-wide and front lens.

In Night Mode, the iPhone shoots multiple images at varying exposures. The iPhone will suggest a length of time for Night Mode and you have the option to extend that up to 10 seconds. The longer the time, the more shots and exposures the iPhone will capture. It’s important to keep your hands steady or even use a tripod to avoid any movements. Through some software magic, the iPhone will then combine the images to create one.

Shot for shot, images look brighter on the 12 over the 11 and keep more details in the photo. The processing of the image is a second or two faster as well. So, while these miniscule changes do add up to a crisper visual, an untrained eye still would have trouble noticing the differences between images taken on the 12 and on the 11. (Those coming from earlier phones will see big improvements in low light, especially considering that there isn’t a Night Mode on those devices).

iPhone 12 in hand, we headed back to The Metropolitan Museum of Art in NYC to try and match our favorite shot from the iPhone 11 and 11 Pro last year: the Met at night with traffic zipping across. Quality was definitely as good as we expected and it still managed to produce a stop motion effect on a taxi with proper colors. With The Met behind, we could make out lighting within the windows, details of the steps and classic food carts parked out front. You can opt for the Ultra Wide lens to capture a 120-degree field of view and have Night Mode work its smarts. There is even lens correction done automatically to remove any fisheye effect from the corners.

Night Mode selfies are quite impressive and really light up your face, although some detail can be lost, especially with the front-facing camera. It’s much better than using the screen as a flash as previous iPhones did. It still uses a toned-down version of this flash, but also uses software to intelligently light the shot. It should up your iMessage, Snapchat and Instagram story game, though.

Most impressively throughout the different shooting modes was how the iPhone 12 can handle different levels of brightness in the same shot. For instance, the sun shining bright from the top left over an apple orchard with a grove of trees creating shadows on the right. It can manage the different levels of lighting on it’s own, without causing overexposure from one side. On a Samsung device, you might need to play around with different settings modes and even mess with exposure settings. On the iPhone 12, the phone handles all of that for you, so all you have to do is point and shoot.

Portrait Mode got some improvements here as well. Notably, we noticed that hair-lines around people and dogs are more precise. You won’t accidentally cut off a few strands or a chunk of someone’s head. Fun positions, like arms out or jazz hands, are easier to capture as well. And if you never liked the “need more light” notification, the increased aperture of the wide lens allows you to capture these Instagram-worthy shots in darker conditions.

OLED makes all the difference

The iPhone 12 has an OLED screen (a jump from the iPhone 11’s LCD display) and it’s on par with the iPhone 12 Pro.

It’s a Super Retina XDR display with True Tone, a technology that uses sensors to adjust the temperature of the display to your environment. It’s a vibrant picture that really immerses you with colors that pop, whether you’re scrolling through Instagram or playing games.

With an OLED panel, it’s the individual pixels getting an electrical current to display color and create the image. That means an image can look very specific and detailed. Similarly, on the pixel level, it doesn’t need to turn one on full blast when it’s not needed. And that delivers deep black and strong contrast on the iPhone 12’s display.

It packs a much higher resolution also — 2532 X 1170, which measures out to 460 pixels per inch. If you’re coming from an iPhone 11, you’ll see a big difference. And if you’re coming from an older device (like an iPhone X, 8, 7, 6s or 6), you’ll see a huge one.

The main thing the iPhone 12 display is missing would be a high refresh rate, essentially this is the specification that shows how many times in a second the screen can refresh itself. While other smartphones, namely Android ones, have been offering 120Hz displays this year, Apple is sticking with 60Hz across the entire iPhone 12 family. While 60Hz has long been the standard, some games and fast moving content can look less fluid compared to 120Hz. It would have been nice to see, but with average tasks you should be just fine.

A few abrasions showed up on the screen

Apple is touting its Ceramic Shield technology, which provides up to four-times the drop protection on the screen than earlier models. So, in theory, when an iPhone 12 drops and lands on the display, the chances of the display shattering are less. But, as we’ve seen in recent years as glass and screens build up resistance for cracks and deep scratches, the level of pressure or hardness needed to cause a micro abrasion or a light scratch has lessened.

Well, lo and behold, we noticed scratches on the screen of both our iPhone 12 and iPhone 12 Pro units.

Our current theory is that when the 12 and 12 Pro were stacked together with the lenses facing the display, it resulted in a series of hairline scratches that you can’t even feel with a finger. At first we thought they were deep smudges and tried using Whoosh, iCloth, Alcohol Wipes and microfiber cloths to clean them off. But they’re certainly in there. The scratches don’t really cause any issue to the device; it’s more of an annoyance when the screen is off and the light hits it right.

In short: Opt for a screen protector to protect your investment.

iOS 14 flies with the A14 Bionic

The iPhone 12 comes with iOS 14, specifically 14.1, out of the box. And we’ve already detailed our favorite features of iOS 14 in our preview guide.

Year over year, with everyday tasks, you likely won’t see an improvement from a device with an A13 Bionic inside. To notice the difference from those devices, you’d really need to push it with a high performance game or a big high-res photo export. But if you’re coming from an A12 Bionic or earlier, the speed improvements will be completely evident.

The A14 Bionic is the full chipset for the iPhone 12. It’s made up of a six-core CPU, a four-core GPU and a Neural Engine (this by itself is 16-cores). The A14 is built on a 5-nanometer process versus the 7-nanometer process of the A13 Bionic. All of these components make up the chip and work hand-in-hand with iOS 14. Keep in mind that unlike a majority of other smartphones, Apple makes both the hardware and the software. The teams can be in communication every step of the way for design and launch of the iPhone.

In comparison to an iPhone 11, it’s the same speedy experience. Completing a big export in Pixelmator or Photoshop may result in you getting the image a second or two earlier, for instance. Those coming from anything earlier, though, will notice a more efficient software experience. It just glides along. We were hard pressed to make the iPhone 12 slow down through a normal day of work and play with applications like Slack, Mail, Outlook, Chrome, Safari, TikTok, Twitter and Instagram (frequently even keeping upwards of 25 applications open in the background, which is enough to make other smartphones bottleneck).

Face ID is still pretty rapid when you’re not wearing a mask. Maybe Apple will add Touch ID in the form of the power button (like on the new iPad Air) or under the screen next year, but for now keep masking up and triggering the unlocking number pad to show up.

We threw several games at the iPhone 12: Numberzilla, ToyStory Drop, Real Racing 3, Shadow (which has us connecting to a powerful gaming PC to test latency), Real Flight Simulator Pro, Butter Royale, Mini Motorways and a few others. The more basic titles didn’t really show much improvement compared with an iPhone 11. Compared to an XR, X or 8, though, gaming did feel more prompt and responsive. Toy Story Drop was able to load in quicker, and if it was a multistep move with pieces flying off the board, it happened with no latency. Real Flight Simulator Pro and Butter Royale handled frame rates a bit better here and we noticed improved times when reneding the game or match.

Solid battery life

Over the first few days, battery life was a little short as the iPhone 12 was still indexing. Whether or not you do a restore from backup — we recommend setting up your new iPhone clean — there is still some indexing. In our case, Messages in the Cloud, a large music library and a photo library took a bit to fully sync. 5G speed tests did eat up a healthy amount of battery though; the iPhone 12 did not get uncomfortably warm during this, though.

We found that the iPhone 12 completed indexing after about two days and we were able to get through a full day on one charge, averaging about eight to 10 hours of screen on time. That’s slightly short of the nine to 11 hours that we got on the iPhone 11. In fact, with minimal use, the iPhone 11 could last over 24 hours thanks to the combination of an LCD display and the efficient A13 Bionic chip. Even so, the iPhone 12 is certainly strong enough to get you through a full day.

We also ran the iPhone 12 through the CNN Underscored battery test. In it we play a 4K video on loop with the brightness set to 50% and volume at 30% with the device in Airplane Mode. We also ensure that Wi-Fi and Bluetooth are turned off and play the video on a loop until the device dies. We monitor the test with two cameras for redundancy. The iPhone 12 lasted for 12 hours and 30 minutes.

The iPhone 12 sports fast charging support as well, with a cord and at least a 20-watt wall plug you can get 50% in about 30 minutes. We were able to test this and met the mark.

The new MagSafe charger is really a joy to use and the only way to get 15-watt speeds when wirelessly charging. Qi-enabled chargers are locked to, at most, 7.5-watts. If you’ve ever had the frustration of laying a device on a charging pad and waking up to no juice, this will fix that.

It’s just an experience that’s inherently Apple and will solve a big frustration of many. We’re excited about third-party accessories and future MagSafe products from Apple.

Five colors in a new design

With the iPhone 12, Apple is making better use of space especially in comparison to the iPhone 11. It’s about 15% smaller in terms of volume, but keeps the same 6.1-inch display. Apple did manage to make the bezels slimmer here as well. You still get a glass finish on the back that has some gloss and shine to it. The good news is that it’s not super slippery and provides some grip thanks to a coating. It’s easier to hold in comparison to Galaxy Note 20 or S20.

A big change lives underneath the glass back, though. There’s not just a Qi-enabled wireless charging coil, but rather a MagSafe charging system. Essentially, it’s a wireless charging coil that supports up to 15-watts (a big improvement from 7.5-watts) and has magnets around it. This helps to ensure the MagSafe wireless charger, a new $39 accessory from Apple, properly aligns and stays stuck to the back of the phone.

Antennas for 4G LTE and 5G are etched into the aluminum siding of the iPhone 12. Most noticeable is a long oval piece on the right hand side that houses the mmWave antenna for 5G Ultra-Wide Band on supported networks. It’s a darker blue and, while you’ll notice it, it doesn’t impact the design all that much. The power button is found higher up on the right side. The volume up, volume down, sound silencer and SIM card slot are all found on the left side. On the bottom of the device is a Lightning port that’s flanked on either side by speakers. The iPhone 12 features an IP68 water resistant rating. That means it can stay in up to six meters of water for up to 30 minutes.

The iPhone 12 feels quite comfortable in the hand and we especially like the length of the buttons (volume and power) as it makes it easy to find them — and continues the sizing we first saw on iPhone 11 and 11 Pro.

Bottom Line

At $799.99, the iPhone 12 hits a sweet spot in the smartphone space. You’re getting an expansive 6.1-inch OLED screen, a sleek build in a fun color, dependable camera lenses that offer low-light smarts and a fast A14 Bionic chip. All of these features — including 5G support — should keep this smartphone a viable option for three to four years to come.

But the big question: Should you upgrade?

If you have an iPhone 11 and are happy with it, you’re good to stick with it. Unless you want a better display, you’re getting a pretty similar experience all around — especially if you’re not in an area with 5G connectivity.

If you have an older iPhone, though, it’s a no-brainer — upgrade to the iPhone 12 to future proof yourself with 5G, on top of the clearcut improvements in terms of faster operating prowess, superior cameras and a crisper display.

Not to mention, there are some tremendous deals from AT&T, T-Mobile and Verizon that, with proper trade-in, let you get an iPhone 12 for free. And if you can do that, well then we wouldn’t blame you at all. Even if you have an iPhone 11.
