iPhone 13 in Depth: Performance, Camera, and Battery Tested

Introduction: iPhone 13

By contrast, the iPhone 13 released in September 2021 took a smaller step forward in Apple’s smartphone development. While it maintained the flat-edge design that debuted on the iPhone 12, that phone was one of Apple’s best-balanced iPhones in years (as long as you were cool with the notch).

The iPhone 13 comes in five exciting finishes and an upgraded 6.1″ Super Retina XDR display with incredible brightness, contrast, and color accuracy for all your daily tasks, gaming sessions, and video content consumption. On iPhone 13 mini is Apple, A15 Bionic chipset that offers more processing performance, smoother graphics and longer battery life than previous generations.

The dual camera system on the back is now in a diagonal arrangement and includes sensor shift stabilization—previously exclusive to the iPhone 12 Pro Max—that further improves stills and video, especially all those low light shots. Shooting on my iPhone 13, I wondered how the focus transitions in my mobile video compared to Hollywood.

While the iPhone 13 does have better battery life and 5G connections, supports MagSafe accessories, and runs iOS 15 (and will run future versions of iOS as well), it is a divisive choice at best since Apple may just be seen as accommodating against the marketing-driven Pro Series with its major product decisions that again strike a balance between performance, style,and affordability for many users.

Unboxing iPhone 13

The iPhone 13 packaging leans into the minimal aesthetic in a way we have not yet seen in previous models. The box is even slimmer than the boxes that older iPhones came in as Apple has ditched the power adapter and EarPods as it continues efforts to cut down on electronic waste.

The iPhone 13 is seen flat in the compact white box(top), revealing a noticeable visual change from its predecessors with a new diagonal dual-camera system. Apple says this paper screen cover is in keeping with its sustainability goals; the phone is protected by paper instead of plastic.

At the bottom of the box is the USB-C to Lightning cable for charging and data sync. Along with the USB-C cable and five-watt power adapter, you have a SIM ejector tool, some documentation in a small packet, and yes: an Apple sticker.

Fast charging is however siphoned into the phone via a wall wart — with no brick included users will need to have one lying around or buy another one to make use of the faster speeds. The basic unboxing and packaging is simple, clean, and gets you up and running in under five minutes.

There is virtually nothing inside, but the iPhone 13 manages to feel premium when you take it out of a box, mostly because Apple has nailed the unboxing, and also due to how nicely made the device is.

Design: iPhone 13

The iPhone 13 is part of Apple’s latest design philosophy, which focuses on a thin yet sturdy construction that provides an excellent compromise between style and performance. It keeps the flat-edge aluminum frame that first arrived with the iPhone 12, helping give it a sturdy, high-quality feel in the hand — as well as lending extra grip and protection.

On the front is Apple’s Ceramic Shield glass, which it says is the toughest screen on any smartphone. The rear is glossy glass with a slippery finish and comes in bright colors such as Starlight, Midnight Blue, Pink and (PRODUCT) RED.

A diagonal rear-side camera line-up which is a vis-à-vis iPhones first-based design change. That not only offers a material difference from the iPhone 12 but it also makes room for a larger camera sensor in the small dual-camera array.

The only other minor visual differences are the top-notch cut into the screen—ever-so-slightly shorter than before, giving you just a smidge more usable space while keeping all that Face ID and front camera hardware in place.

A 7.65mm thickness and a weight of 174g make the iPhone 13 feel petite, well-weighted and easy to handle. But rather than a step forward from the iPhone 3GS to the 4, this is an enormous robo-leap — it’s one of the nicest electronic devices I’ve ever used because you can tell that every bit of detail has been sweated over.

Build Quality: iPhone 13

Apple is known for making long-lasting, premium smartphones and the iPhone 13 is no exception with beautiful build quality. The aluminum frame of the bike is robust without being overbuilt and strikes a good compromise between lightweight handling and long-term structural rigidity. The back further consists of glass with a shiny finish and can at times appear elegant and svelte but can also be quite the fingerprint magnet, so we recommend some sort of case.

It has Apple’s Ceramic Shield material built from nano-ceramic crystals to help with drop protection on the front. According to Apple, it is stronger than any other smartphone glass, and I have not found this argument to be misplaced during everyday use with respect to scratches and normal crashes.

The device comes with an IP68 certification which means that the phone is dust-tight and water-resistant up to 6 meters for 30 minutes, this should provide a peace of mind for everyday spills, rain or accidental submersion.

The buttons, ports and seams are all machined with precision — the haptic feedback is taut and snappy. Design & Craftsmanship: SIM Tray, Lightning Port, Mute Switch.

The iPhone 13 is solid and well-balanced in the hand. Its construction is incredibly solid and well-appointed for its price range, even if it lacks the stainless-steel frame of the Pro models — a luxury that has negligible benefits when push comes to shove.

Controls and Connectivity: iPhone 13

When it comes to controls and connectivity, the iPhone 13 maintains an efficient and simple layout—a design that excels at ease of use. On the left there is a mute switch and volume up/down keys that are tactile and responsive, but positioned where you sensitive hand can get to them quite easily with one thumb. The right side features the Side Button (a.k.a. power button), which is used to turn on:off the screen, activate Siri and trigger Apple Pay.

This of course uses the familiar Apple Lightning port but you’ll find it at the bottom of the device. Users have for the most part been calling for USB-C but Apple sticks with Lightning on the iPhone 13, and can continue using a wide lineup of accsessories and docks.

As for wireless, the iPhone 13 has 5G to provide quicker mobile internet, Wi-Fi 6 for faster and more stable wireless experience, and Bluetooth 5.0 for reliable audio and peripheral interactions. It comes with NFC for Apple Pay as well.

The iPhone 13 also has dual SIM support (nano-SIM + eSIM), which is ideal for when travel returns and users need a work number separate from their personal one.

Lab Tests: Display – iPhone 13

The iPhone 13 display renders bright contrast, accurate colors in lab tests The display is 6.1 inches large with Super Retina XDR OLED aspect, boasting a resolution of 2532 x 1170 pixels (~460 ppi) that provides legible text and punchy colors.

In our testing, Samsung proved to hold up its promise as well with peak brightness reaching 800 nits in standard usage and even going beyond 1,000 nits under HDR playback which makes it bright enough for sunlight visibility. Countless contrast levels provided by the OLED technology with real blacks make it one of the best displays for streaming videos or playing games.

Color accuracy is also excellent. And that the iPhone 13 also supports P3 wide color gamut and True Tone (which as we said, adjusts white balance based on ambient lighting). Lab-calibrated measurements result in very low delta-E scores—or exceptional color accuracy—and it is a great choice for creatives and content viewers.

It doesn’t offer the 120Hz ProMotion refresh rate on the Pro models, but Apple’s touch response is so good and software optimizations are so solid that 60Hz still feels smooth and motion remains fluid for everyday tasks.

In any case, the results of our labs tell us one thing: the iPhone 13 display is a super-good panel in its class that will satisfy all customers with excellent brightness, contrast and color reproduction params that make up an extremely pleasant picture.

Battery Life: iPhone 13

That A15 Bionic chip has been clocked ever so slightly lower than on other iPhone 13 models, however the combination of the larger battery and iOS software optimizations are helping boost battery life. While that may not be terribly impressive compared to some other Android phones, Apple’s performance optimizations with hardware and software together mean the battery performs incredibly here.

Apple claims 75 hours of audio playback, up to 15 streaming and over 19 video in both its lab and real-world tests for the iPhone 13. This typically translates into an all-day — and then some — mixed use scenario for most users, meaning browsing, calling, social media-ing, snapping photos, or even streaming video.

The iPhone 13 impresses under the most demanding situations, using both maximum network connectivity with 5G on and high screen brightness. The standby time is also one where the iPhone 6 Plus shines and that is partially to do with how well iOS can manage background activity and some of Apple’s specialized deep sleep optimizations.

The device is capable of 20W fast charging for faster refueling, with a compatible USB-C to Lightning adapter taking it from empty to a 50% charge in around 30 minutes. It also features 15W MagSafe wireless charging as well as 7.5W Qi standard wireless charging.

The iPhone 13 easily meets those demands, and its consistent long-lasting battery life makes it a solid option for casual users as well as heavy usage cases.

Charging Speed: iPhone 13

Though, it does still support fast charging — albeit not the ultra high-wattage stuff you’ll find on some Android competitors. It supports up to 20W wired charging with a USB-C power adapter and a USB-C to Lightning cable. Indeed, Apple says you can replenish the battery from 0 to about half full in 30 minutes — a claim I found accurate in real-world testing.

It usually takes 90-100 minutes to fully charge with an official or high-quality third-party 20W charger. We also suggest keeping in mind there is no included charger in the box, just a USB-C to Lightning cable, so you’ll need to invest in a charge adapter if this will be your first iPhone 12 purchase.

MagSafe support for up to 15W is great (so long as you align it properly and have good thermal management). Of course, the device also supports 7.5W standard Qi wireless charging for overnight charges.

Though the iPhone 13 isn’t industry-leading with the raw speed of its top-up, the fact it is always safe and reliably quick means we expect you’ll get your device back to capacity quickly enough for most day-to-day use — especially if you’re keeping it juiced up overnight or through random charges through the day.

Loudspeakers: iPhone 13

This smartphone is an excellent audio performer too with its stereo speakers that Apple calibre to offer ample loudness and balanced sound. The bottom-firing speaker system is complemented by a secondary speaker integrated into the earpiece at the top, helping to bounce out that sound for balanced stereo in both portrait and landscape orientations.

The iPhone 13 delivers clean and loud sound with little distortion even when cranked all the way up in both real-world usage and our lab tests. It works ideally for watching content, playing games, or listening music out loud. It delivers solid depth in vocal reproduction and decent bass presence, especially for the size of a phone belonging to this output.

Apple says it has also subtly tweaked speaker tuning for what should be clearer sound and improved dynamic range over older models. When I watched videos in landscape, the stereo separation was fantastic and added a layer of sound that enhanced the experience.

Yes, while these loudspeakers do not pack as a powerful a punch in a phone like some of the larger speaker chambers on Android flagships, they are hands-down the best in class and well-suited for calls on speaker, podcasts or general media consumption.

Adding spatial audio with Dolby Atmos support (especially when using AirPods or a compatible accessory) transforms the iPhone 13 listening experience beyond its built-in speakers.

Software: iPhone 13

The iPhone 13 arrived with iOS 15 out of the box and it will be update to iOS 17, when Apple introduces them. It also has that iOS-like smooth, stable and secure user experience which is one of the biggest reasons keeping people on an iPhone since Apple has a tight integration between hardware and software.

iOS has a neat and clean appearance, is easy to use for gestures, and privacy and security are high. Apps and animations open fluidly, system navigation is zippy, even on the 60Hz iPhone 13 screen. With Apple’s regular, long-term updates, you always get the latest features and security patches — usually for 5+ years; they really preserve the iPhone 13 so that it will remain relevant far into the future.

It will also be able to run all the latest iOS features, such as Focus Mode, Live Text, FaceTime improvements, customizable lock screens (iOS 16) and StandBy mode in iOS 17. The iPhone SE also plays nice with the Apple ecosystem, syncing with AirPods, MacBooks, Apple Watch and iCloud.

With an impressive array of features from multitasking and widgets to Siri and privacy reports, the iPhone 13 offers a smooth, quick, and easy software experience. It’s built for your average everyday user as well as the power user who needs reliability and ease of use.

Performance: iPhone 13

The iPhone 13 is powerful and does everything very quickly, thanks to Apple’s own A15 Bionic chip that remains one of the top mobile processors currently available. The A15 uses a 5nm fabrication process and includes a 6-core CPU, a 4-core GPU, and a 16-core Neural Engine for snappy performance that’s also efficient across all tasks.

According to benchmark tests, the iPhone 13 continues to perform well against many Android flagships. However, and more importantly than numbers is the real-world usage: apps open instantly, multitasking draws little effort and even demanding tasks like video editing or augmented reality run without any delay.

The Neural Engine powers on-device AI like image processing, voice recognition, and Live Text. The tablet is really snappy in everyday use — messaging, browsing, social media or navigation.

The iPhone 13 is a gaming machine. Titles such as Genshin Impact, Call of Duty Mobile and Asphalt 9 run on high settings with smooth frame rates and fast loading times. And the Red magic 6 is robust enough to maintain consistent performance over hours of gameplay thanks largely due to good heat management.

The iPhone 13 provides flagship-level speed that might not seem super high-end in the context of a year filled with Pro models, but it’s still fast, reliable and plenty capable for those who seek power without the extras provided by Apple’s more expensive phones.

Camera: iPhone 13

The most powerful dual-camera system ever introduced in an iPhone 13 brings advanced features to the non-Pro phone. Here are the specifications of the camera rear: 12MP wide camera (f/1.6) sensor-shift optical image stabilization and and a 12MP ultra-wide camera (f/2.4) with a view of 120° This diagonal camera layout is not just for show and has been designed with larger sensors to improve low-light performance.

It quickly takes sharp, detailed pictures with nuanced dynamic range and faithful colors. When it comes to photos, all three cameras benefit from better computational photography with Smart HDR 4, Deep Fusion and even Night Mode now supported across the lenses. In both bright daylight and dimly lit scenes, exposure, shadows and even skin tones are accounted for beautifully by the iPhone 13.

It uses Photographic Styles, a function that will allow users to make live tone and warmth adjustments without wiping facial features off thanks to the fact is not based on traditional filters. More depth effects and new lighting styles for improved Portrait Mode

From the video standpoint, the new iPhone 13 can shoot 4k at up to 60fps, use cinematic mode with rack focus effects and show off Dolby Vision HDR, which make it a great device for content creators or simply casual videographers.

Photo and Video Quality: iPhone 13

The iPhone 13 shoots great photos and video, especially considering it has only a dual-camera system. The 12MP wide and ultra-wide lenses deliver sharp, detailed shots with strong color and great dynamic range in well-lit situations. It also makes balanced exposures even out from scenes with strong backlight or mixed light, thanks to Smart HDR 4.

It also posts strong low-light performance, due to its larger sensor and sensor-shift image stabilization (which is borrowed from the iPhone 12 Pro Max). An upcoming Night Mode automatically switches on in low-light areas, protecting texture and reducing noise. The ultra-wide lens is still plenty sharp in bright light for taking wide-angle shots of landscapes or a large group of people.

The iPhone 13 is incredibly strong in video recording That does 4K at 24/30/60fps, 1080p slo-mo, and Dolby Vision HDR — in other words, broadcast quality right from your pocket. One of the new features, known as Cinematic Mode brings shallow depth of field and focus changes right out of the gate which makes your videos look like they were shot by a professional.

Stabilization is fantastic and the audio quality is clean, so the iPhone 13 is perfect for vlogging, casual filmmaking, and social content. Whether you shoot photos, or videos, the iPhone 13 is sure to deliver and does so in a polished package for great results with ease of use.
