The iPhone 13 strikes a balance between price, size and features that suit most people, so it is no surprise that it is the best-selling iPhone in Apple's lineup, but how does it compare against its predecessor, the iPhone 12

Visually, there are only a few design changes in the form of a new diagonal camera on the back, a smaller notch and a very slight gain in weight, but while it looks similar on the outside, under the the hood, Apple has added a welcome boost to the iPhone 13 battery life, upgraded the cameras, made it all faster and given us a few other surprises. Unfortunately, a 120Hz refresh rate is not one of those surprises.

Display and Design

6.1" OLED screen, but no 120Hz ProMotion

For the most part, the iPhone 13 keeps the size and design styling of the iPhone 12, and that also means it will come a flat, 6.1" screen. This size has proven to be a great middle ground, a bit larger and more useful than the smallish 5.8-inch screen that Apple used to have on the iPhone X, XS and 11 Pro, but not too big either. What the iPhone 13 does not have is 120Hz ProMotion technology for smoother scrolling, which is available on the iPhone 13 Pro series. 

The iPhone 13 display looks mostly the same, but there are some slight changes. The size and resolution remain unchanged, but the notch is now 20% smaller (Apple hasn't done anything meaningful with the space that's freed up except for using a larger font for the time and battery icons). Another welcome change is an increase in brightness as the 13 can no go to as much as 800 nits, compared to 625 peak brightness on the 12, and this does make for easier viewing outdoors.

There are also some new colors, while some old colors are gone. For example, you no longer have a green model, but you do get a pink version in the iPhone 13 that you can see above. We are also big fans of the new lighter shade of blue compared to the darker, almost navy blue hue on the iPhone 12 above. And yes, the two cameras are now aligned in diagonal rather than a straight line. 

The one more substantial change that you may actually feel though is that the iPhone 13 now weighs 174 grams, a bit more than the 164 grams of the iPhone 12. It's a subtle thing, but you could notice it. What you probably won't even notice is that the newer phone is just a tad bit thicker at 7.65mm vs 7.4mm. 


Cameras
Dual camera setup, upgraded

In the past couple of years, Apple has adopted a clear strategy to differentiate iPhones, equipping the non-Pro models with two cameras, but without the third one, the zoom lens that you get only on the Pro models. The iPhone 13 follows that rule and also skips the telephoto lens, but does bring an upgrade to its two rear cameras.

Here is the camera hardware on the iPhone 13 and iPhone 12:

  • Wide camera — 12MP on both, 26mm, f/1.6 aperture on both
  • Ultra-wide camera — 12MP on both, 0.5X, or 13mm; f/2.4 aperture on both

While you still have 12MP sensors, Apple says the main camera can now capture capture more light, up to 47% more, for better night shots. Additionally, you get new sensor-shift OIS for better stability. And the ultra-wide camera is advertized to show more detail in the shadowy areas. So... let's take a look at the actual pictures!


As you can see above, the differences in daylight with the main camera mostly boil down to some variation in colors, but nothing major. The iPhone 13 seems to tone down the exposure of the highlights for a more balanced image, while the photo from the iPhone 12 looks a tiny bit overexposed.


And here is one more shot with both phones, where you can notice something similar: the mids and the highs of the photos have a bit lower exposure, and interestingly the image has a bit less saturation on the iPhone 13.


We were more curious about the low light shots, where Apple promises bigger improvements and while we wouldn't say it's a night and day difference, we can spot the sharper and cleaner definition of the iPhone 13 photo above.


We're in for a bit of a surprise with the ultra-wide camera, though. The iPhone 12 here actually captures the brighter photo and while detail is mushy that is the look that grabs the eye more. Just to make sure, here is one more shot with the ultra-wide camera at night:


Yep, that's indeed the norm with the iPhone 13 at night. It would capture darker photos with the ultra-wide camera, which is probably a bit more realistic but also not quite as impressive at first sight. You can manually tap the night mode button in the camera app and force a longer exposure to get a brighter shot though, and that would have slightly cleaner detail than the iPhone 12.

There are a few new software features too. We touch upon them in more detail in the articles below:

  • Cinematic Mode — similar to Portrait mode, but for video. The new iPhone will analyze video footage in real time and blur the background for a so called bokeh effect, leaving only the subject in focus.
  • Photographic Styles — way more powerful than traditional filters. These new AI filters will allow you to adjust colors, highlights and shadows on individual elements of a photo (be it an object or a person).

While early pre-release rumors claimed the iPhone 13 will get a LiDAR scanner, the retail phone does not have it, and this sensor is left for the Pro models only.

Performance, Apple A15 and Storage

Double the storage for the same price is great news


Apple makes its own A series of chips for iPhones and they have led the market in terms of performance in the past few years, and this lead only continues with the new Apple A15 Bionic processor.

The iPhone 13 also has the same 4GB of RAM as the iPhone 12, but the base model now has 128GB of storage, double the predecessor at the same price and that is awesome.

The Apple A15 chip is built on 5nm technology, same as last year, but it has 15 billion transistors vs 11.8 billion transistors on the A14 chip.

Below, you can find benchmarks comparing these two:

Higher is better
Apple iPhone 13
1728
Apple iPhone 12
1594

There is slight improvement in speed, and analysts have pointed out that it is probably due to Apple bumping CPU speed for better single-core scores and increasing the cache that helps with multi-core results.


For GPU performance, we turn to the 3D Mark Wildlife Stress test. This is our preferred method of testing because it shows not only the initial burst of speed you get, but more realistic numbers as it runs straight for 20 minutes and shows how the results vary and if the phone throttles. The GPU performance increase we measured over the iPhone 12 is actually quite minuscule here, and towards the end we noticed the iPhone 13 actually throttled and scored even a bit below its predecessors.

We have also thrown in the results of the iPhone 13 mini here because they show an interesting difference: the mini throttles far earlier than the regular 13, just after 10 minutes, while the regular 13 only throttles towards the very end of the test. For gamers that might be an important distinction as the bigger iPhone 13 definitely has more thermal allowance to run intense games longer.

Finally, we have to mention that Apple throws in 128GB of storage in the base model, double the miserly 64 gigs we used to have in the iPhone 12 and that is great, all for the same price. You also get a new 512GB iPhone 13 tier, while the 12 used to only be available at up to 256GB.

Battery and Charging

iPhone 13 has longer battery life


The iPhone 13 brings a battery boost, and while Apple does not provide the battery capacity numbers, tear-downs have revealed that the iPhone 13 has a 3,227mAh battery cell vs 2,815mAh in iPhone 12, a nearly 15% increase in capacity.

What Apple does confirm is that you will get 1.5 hours longer battery life on average, and digging further in Apple documents we find that the iPhone 13 can now last 15 hours of non-stop video streaming, a huge upgrade over the 11 hours that the iPhone 12 can handle. These are official Apple numbers, folks!

Browsing test 60Hz (hours) Higher is better
Apple iPhone 13 13h 43 min
Apple iPhone 12 12h 33 min
Video Streaming (hours) Higher is better
Apple iPhone 13 8h 15 min
Apple iPhone 12 6h 38 min
3D Gaming 60Hz (hours) Higher is better
Apple iPhone 13 7h 28 min
Apple iPhone 12 6h 46 min

Looking at our very own three benchmarks, we can see that battery life has indeed received a welcome boost. On our lightest web browsing test, the iPhone 13 scores nearly 14 hours compared to 12 hours and a half on the iPhone 12. You get a meaningful upgrade in the YouTube video streaming results as well as for gaming where the iPhone 13 outlasts the 12 by a good 2 hours. Impressive!

On the charger front, Apple "innovated" by not including a charger or headphones in the iPhone 12, and this beautiful innovation carries over to the iPhone 13. Apple paints this as an eco move, but you can easily also see this as a simple price-cutting manoeuvre. Whatever it is, plan on spending an additional $20-$30 bucks for a fast charger for the iPhone 13.

As to charging speeds, Apple has been slow to adopt the super fast charging that we see on many Android phones. We have the same 20W wired charging speeds for iPhone 13 and 15W wireless charging speeds with a compatible MagSafe charger.

iPhone 13 vs iPhone 12: Specs Comparison


And here is a detailed specs comparison between the iPhone 13 and iPhone 12.


Finally, the iPhone 13 prices remain absolutely unchanged, but you do get double the storage, along with all the new features we talked about above. We can definitely see Android phone makers worried as Apple improves the biggest sore point in its devices, the battery life, and yours truly is actually very excited about the iPhone 13.

But what about you, do you think Apple has delivered with this iPhone 13 upgrade over the iPhone 12?
