iPhone 12 Screen Size: Dimensions, Specs, and Comparison

A phone’s screen size is often the first question buyers ask — and the iPhone 12’s 6.1-inch display has become something of a benchmark. With its Super Retina XDR OLED panel, the iPhone 12 sits at a size that many still consider ideal.

Screen size (diagonal): 6.06 inches ·
Display type: Super Retina XDR OLED ·
Resolution: 2532 x 1170 ·
Pixel density: 460 ppi ·
Aspect ratio: 19.5:9

Six key specs define the iPhone 12 display — here they are at a glance.

How big is the iPhone 12 screen size?

What is the exact diagonal size?

• Apple lists the iPhone 12 display as 6.06 inches diagonally when measured as a standard rectangle (Apple’s official iPhone 12 specs page (manufacturer)).
• The actual viewable area is slightly less due to rounded corners and the notch.

What type of display does it have?

• It uses a Super Retina XDR OLED panel — the same technology that debuted on the iPhone 11 Pro (Wrappz (device comparison blog)).
• All iPhone 12 models replaced LCD with OLED, making the standard iPhone 12’s screen noticeably richer than the iPhone 11’s Liquid Retina LCD.

What is the resolution?

• Resolution: 2532 x 1170 pixels at 460 ppi (Apple’s official iPhone 12 specs page (manufacturer)).
• In developer logic, the screen measures 390 x 844 points (Use Your Loaf (iOS developer reference)).

Why is the iPhone 12 discontinued?

What led to the discontinuation?

• The iPhone 12 was pulled from sale in France in September 2023 after the French regulator ANFR ruled it exceeded SAR limits for electromagnetic radiation (Tech Wire Asia (tech news outlet)).
• Apple released a software update to reduce SAR levels, but the ban remained in effect for several weeks.

Was it due to radiation concerns?

• Yes. The dispute centered on the iPhone 12’s radio-frequency exposure, which ANFR said exceeded the legal limit of 4 W/kg for limb measurements (Tech Wire Asia (tech news outlet)).
• Other markets (Belgium, Germany) also reviewed the issue but did not issue sales bans.

What this means: The discontinuation was regulatory and geographically limited — it doesn’t affect existing iPhone 12 users elsewhere, but it ended new sales in a key European market.

Is 76% battery health ok?

What does battery health percentage mean?

• Battery health reflects the maximum capacity relative to when the battery was new. A reading of 76% means the battery now holds only 76% of its original charge (Asurion (device repair/care guide)).
• Apple considers any reading below 80% as degraded and recommends replacing the battery to maintain peak performance (Asurion (device repair/care guide)).

When should you replace the battery?

• If you’re experiencing unexpected shutdowns or slowdowns — especially in cold weather — a replacement is advisable.
• Apple charges roughly $89 for an out-of-warranty iPhone 12 battery replacement as of 2025 (Apple Support (official service info)).

How many years are left for the iPhone 12?

How long does Apple support iPhones?

• Apple typically provides major iOS updates for 5–6 years after a device’s release (Macworld (tech analysis)).
• The iPhone 12 launched with iOS 14 in October 2020 and is currently supported by iOS 18 (as of 2025).

What is the expected end of software updates for iPhone 12?

• Major iOS updates likely end in 2025 or 2026 (Macworld (tech analysis)).
• Security updates may continue for another year or two after the last major release, following Apple’s typical pattern.

The implication: If you’re still using an iPhone 12 in 2025, you’re approaching the end of the road for new features. However, most apps will still work for several years after major updates stop.

What is the iPhone 12 screen resolution?

What is the pixel count?

• The iPhone 12 display has a resolution of 2532 × 1170 pixels (Apple’s official iPhone 12 specs page (manufacturer)).
• This gives a pixel density of 460 ppi — well above the “Retina” threshold for indistinguishable pixels at typical viewing distance.

How does resolution affect display quality?

• At 460 ppi, text appears sharp and images look crisp, even when the phone is held close to the face.
• The resolution is identical to the iPhone 12 Pro and iPhone 12 Pro Max (though the Pro Max has a larger panel at 2778 × 1284, 458 ppi) (Apple’s official iPhone 12 specs page (manufacturer)).

One pattern: Apple kept the same pixel density across all iPhone 12 models, ensuring uniform sharpness whether you choose the mini, standard, or Pro Max.

Five iPhone 12 models on the market — and only two screen sizes differ in their physical dimensions. Here’s how they compare.

“The display on the iPhone 12 is a 6.1-inch Super Retina XDR OLED display.” – Apple’s official iPhone 12 specs page (manufacturer)

“When the maximum capacity is below 80%, the battery is considered degraded and should be replaced for optimal performance.” – Asurion (device repair/care guide)

“France halted iPhone 12 sales in September 2023 after the ANFR regulator found the device exceeded SAR limits.” – Tech Wire Asia (tech news outlet)

“Apple typically offers iOS updates for 5–6 years, meaning the iPhone 12’s last major update could arrive in 2025 or 2026.” – Macworld (tech analysis)

The iPhone 12’s 6.1-inch screen was a smart balancing act when it launched — large enough for video and browsing, small enough to hold easily. But the smartphone world hasn’t stood still. Newer displays are brighter, smoother, and larger. For iPhone 12 owners in 2025, the question isn’t just about screen size; it’s about whether the rest of the device can keep up. If you value a pocketable phone with a still-excellent OLED panel, the iPhone 12 remains a capable device. But if you want longer battery life, faster refresh rates, and the latest camera systems, an upgrade to the iPhone 16 (or waiting for the iPhone 17) is a clear path forward.
