Apple’s iPhone 12 set a new standard for smartphones when it launched, delivering a sleek design, powerful performance, and impressive camera capabilities. However, Apple has always been about pushing the boundaries, and with the iPhone, they’ve raised the bar once again. If you’re considering upgrading your device, you may be wondering: is the iPhone worth the investment, or is the iPhone 12 still a great option?
At Used Mobiles 4 U, we understand that making the right choice can be difficult, especially when the differences between the two phones are subtle but impactful. To help you make an informed decision, we’ve broken down the key differences between the iPhone and iPhone 12, including their design, performance, camera capabilities, battery life, and more. Read on to find out which iPhone model is the best choice for you!
iPhone 13 vs iPhone 12: Design and Build Quality
When you first look at the iPhone 12 and iPhone 13, you’ll notice that they share many similarities in terms of design. Both models feature Apple’s iconic flat-edged design with aerospace-grade aluminum edges and a Ceramic Shield front cover that is four times more resistant to drops than previous glass. Both phones are also rated as water-resistant, with an IP68 rating, meaning they can be submerged in up to 6 meters of water for up to 30 minutes without damage. This makes both devices highly durable for everyday use.
However, while the iPhone 12 and iPhone 13 look nearly identical from the front and back, Apple has made a few key design tweaks to the iPhone 13. The front camera on the iPhone 13 is 20% smaller than the iPhone 12’s, allowing for more screen space and a slightly refined notch. This small adjustment makes the screen feel just a bit more expansive. Speaking of the display, the iPhone 13’s Super Retina XDR display has been improved over the iPhone 12’s. It now allows 28% more light to pass through, which translates into brighter, more vivid colors and better visibility in direct sunlight. If you’re someone who enjoys watching videos or gaming on your phone, this improved display will make a noticeable difference in your experience.
Eco-Friendly Materials: Sustainability on the iPhone 13
A key difference in terms of design is Apple’s commitment to sustainability. With the iPhone 13, Apple has taken its environmental efforts one step further by using recycled materials. The iPhone is crafted from upcycled plastics made from plastic bottles, contributing to the reduction of environmental waste. This move aligns with Apple’s goal of making all of its products more environmentally friendly. While the iPhone 12 was already a step forward in this direction, the iPhone 13 truly pushes the envelope in terms of sustainability.
For those conscious of their carbon footprint, this might be a deciding factor in choosing the iPhone 13 over the iPhone 12.
Colors and Variants: iPhone 13’s Fresh New Palette
One of the most fun aspects of choosing an iPhone is picking the color that suits your style. The iPhone 12 was available in a range of attractive colors, including Black, White, Green, Purple, Blue, and Product Red. These colors remained popular throughout its lifecycle, offering a wide range of options for every taste. The iPhone 13, however, introduces a few new shades to spice things up.
While you can still get the iPhone 13 in Blue and Product Red, it also introduces new color options: Midnight, Starlight, and Pink. The addition of Midnight, a darker, deeper shade of black, and Starlight, a subtle off-white color, gives users even more ways to express their style. The new Pink color option offers a fun, fresh look that contrasts with the more professional tones, making it ideal for those who prefer a little extra flair. These new color variants help differentiate the iPhone 13 from its predecessor, making it clear that Apple is not just improving the internals but also adding new visual appeal.
Camera: How the iPhone 13 Shines in Photography and Video
If there’s one area where the iPhone 13 pulls ahead of the iPhone 12, it’s the camera. Both models feature a 12MP dual-camera system with a wide lens and an ultra-wide lens, but the iPhone 13 introduces some important improvements to help you capture the best photos and videos in any situation.
Better Low-Light Performance
One of the most notable enhancements to the iPhone 13’s camera is its ability to capture better low-light photos. Thanks to a larger sensor, the iPhone 13’s main camera lets in 47% more light than the iPhone 12’s, which means you can take clearer and more detailed photos in darker environments. This is a major advantage for anyone who loves to take photos in low-light settings or at night, as the iPhone 13 can reveal more subtle details that might have been lost on the iPhone 12.
Improved Image Stabilization
Another major improvement to the iPhone 13’s camera system is enhanced sensor-shift optical image stabilization (OIS). This advanced feature helps reduce blur, especially in low-light conditions when the camera needs to compensate for camera shake. Whether you’re snapping photos or recording videos, you’ll notice much sharper and more stable images with the iPhone 13 compared to the iPhone 12.
Cinematic Mode: A Game-Changer for Video
The most exciting addition to the iPhone 13’s camera system, however, is the introduction of Cinematic Mode for video recording. This feature brings professional-level focus effects to your videos, making them look as though they were shot on a high-end film camera. Cinematic Mode uses machine learning to detect the subject of your video and adjust the focus dynamically as the scene unfolds. For example, if you’re recording yourself and someone enters the shot, the focus will automatically shift to them, and when they leave, it will shift back to you. This seamless focus transition makes videos feel more polished and cinematic.
In addition to automatic focus shifts, you can also adjust the focus after you’ve filmed your video using the iPhone’s editing tools, giving you complete control over the depth of field. This is a revolutionary feature for anyone who creates content on platforms like YouTube, Instagram, or TikTok, as it elevates the production value of your videos with minimal effort.
Performance: A15 Bionic Chip vs A14 Bionic Chip
The iPhone 12 was already a powerhouse, thanks to its A14 Bionic chip, which was the first 5nm chip in the smartphone industry. With the iPhone 13, Apple has introduced the new A15 Bionic chip, which builds on the A14’s performance and brings even more power under the hood. Apple claims the A15 chip is up to 50% faster than the competition, offering superior performance for gaming, multitasking, and general use.
Machine Learning and AI Capabilities
One of the most exciting new features enabled by the A15 chip is its enhanced machine-learning capabilities. This allows the iPhone 13 to do things like identifying objects in photos, analyzing videos of your activities (such as dance moves or sports techniques), and offering feedback on how to improve. For example, you can use machine learning technology to analyze your golf swing or tennis serve and receive tips on improving your technique. This is just the beginning, and as apps begin to take full advantage of the A15 chip, the possibilities for machine learning on the iPhone will only expand.
Faster Gaming and Better Graphics Performance
For gamers, the A15 chip also offers a 30% improvement in graphics performance, which means smoother gameplay and faster load times. Whether you’re into fast-paced action games or graphically-intensive RPGs, the iPhone 13’s gaming performance will not disappoint. If you enjoy mobile gaming and want to experience the latest titles without any compromise in performance, the iPhone 13 is the way to go.
Storage Capacity: More Room for Your Photos and Apps
Another significant difference between the iPhone 12 and iPhone 13 is storage capacity. The iPhone 12 was available with storage options up to 256GB, but the iPhone 13 goes much further, offering up to 512GB of internal storage. This is a huge leap, especially for users who tend to store a lot of photos, videos, and apps on their devices. The increased storage options on the iPhone 13 mean you won’t have to worry about running out of space as quickly, making it a better option for power users or content creators who need ample storage for their work.
Battery Life: iPhone 13 Outlasts iPhone 12
Battery life is always an important consideration when choosing a smartphone, and in this regard, the iPhone 13 has the edge over the iPhone 12. Apple claims that the iPhone 13 lasts 2.5 hours longer than the iPhone 12 on a full charge. This means you can expect to get more out of your iPhone throughout the day, whether you’re streaming videos, browsing the web, or using apps.
If you’re someone who spends a lot of time watching videos or gaming on your phone, the extra battery life of the iPhone 13 can be a game-changer. For example, with video playback, the iPhone 13 can last up to 19 hours on a full charge, compared to just 17 hours on the iPhone 12. The iPhone 13 mini also gets an extra 1.5 hours of battery life, making it more capable for day-to-day use.
