Apple's Special Edition iPhone line was built for one core purpose: packing flagship processing power into a smaller, more affordable footprint. Choosing the right model means balancing nostalgic compact design against modern connectivity and long-term software support.
The original 2016 model relies on the classic 4-inch iPhone 5s chassis, appealing strictly to minimalists who want a phone that fits easily into a pocket. The second-generation 2020 model shifts to the iPhone 8 body style with a 4.7-inch display and an A13 Bionic chip, offering a bridge between old-school Touch ID and modern performance. The third-generation 2022 model retains that same 4.7-inch exterior but upgrades to the A15 Bionic processor and adds 5G capability, making it a long-lasting compact workhorse.
Design and Display Evolution
Every generation of the iPhone SE chose an existing, proven chassis rather than inventing a new form factor. This approach kept production costs low while recycling reliable manufacturing lines.
- First Generation (2016): Built around a 4-inch Retina display (1136x640 resolution) with chunky top and bottom bezels and a physical home button. It weighs just 113 grams, making it one of the lightest smartphones of its decade.
- Second Generation (2020): Adopted the 4.7-inch Retina HD LCD (1334x750 resolution) from the iPhone 8. It introduced an all-glass back to support wireless charging, pushing the weight up to 148 grams.
- Third Generation (2022): Kept the identical 4.7-inch layout and dimensions of the 2020 model, but swapped the front and back glass for the tougher Ceramic Shield material found on the iPhone 13 series.
While modern flagships moved entirely to edge-to-edge OLED screens and Face ID, the SE series doubled down on physical Touch ID. For users who hate reaching across massive screens or unlocking phones with facial recognition, this traditional setup remains a primary selling point.
Performance and Processing Power
Underneath their recycled shells, each generation marked a massive generational leap in silicon. Apple routinely placed its current flagship processor into its budget lineup, giving these devices a lifespan that outlasts typical mid-range Android competitors.
- A9 Chip (1st Gen): Paired with 2GB of RAM, this chip handled everyday tasks smoothly for years. Today, it struggles with modern web apps and heavy multitasking.
- A13 Bionic (2nd Gen): Equipped with 3GB of RAM, the 2020 model handles standard browsing, navigation, and casual gaming without stuttering. It runs recent versions of iOS comfortably, though intensive background tasks will push its thermal limits.
- A15 Bionic (3rd Gen): Featuring a 4-core GPU and a 16-core Neural Engine, this processor matches the core performance of the iPhone 13. It handles complex machine learning tasks, fluid multitasking, and heavy graphic rendering with ease.
Camera Hardware and Software Processing
Megapixel counts alone never tell the full story of mobile photography. While sensor hardware stayed largely stagnant, computational photography changed everything between these three releases.
The 2016 model features a 12-megapixel rear camera capable of 4K video, which was revolutionary for a budget device at launch. However, it lacks modern Smart HDR or portrait modes.
The 2020 version uses a similar 12-megapixel wide lens but gains portrait lighting, depth control, and Smart HDR through the Image Signal Processor (ISP) of the A13 chip.
The 2022 edition keeps the same physical 12-megapixel sensor, but the A15 Bionic unlocks Deep Fusion and Photographic Styles. Deep Fusion analyzes multiple exposures pixel by pixel to maximize texture and minimize noise in medium-to-low light. If you zoom in closely on foliage or fine text, photos from the third-generation SE look noticeably crisper than those from its predecessor.
Connectivity and Battery Life
Compact phones face strict physical limits when it comes to battery capacity and internal antenna layout.
- Cellular Data: The first and second generations max out at 4G LTE. The third generation introduces 5G sub-6 GHz connectivity, making it much more future-proof as older cellular bands phase out.
- Battery Endurance: The 2016 model features a tiny 1624 mAh battery, requiring a mid-day top-off for almost anyone. The 2020 model improved battery capacity slightly to 1821 mAh, but heavy users often complain about rapid drain during cellular use. The 2022 model leverages the exceptional power efficiency of the A15 chip to stretch endurance significantly further, adding hours of video playback compared to the 2020 variant.
- Charging Speeds: Both the second and third generations support Qi wireless charging and fast wired charging (reaching roughly 50% charge in 30 minutes with a 20W adapter). The first generation lacks wireless charging entirely and charges much more slowly via Lightning.
Common Mistakes When Buying a Used SE
Shooters looking for a budget device on the secondary market often run into a few recurring traps:
- Ignoring software longevity: Buying a first-generation SE today means running an operating system that no longer receives critical security patches. Always check current Apple Support guidelines for active software compatibility before purchasing older hardware.
- Overpaying for storage: Base models historically started at restrictive capacities like 16GB or 64GB. If you plan to store offline media or heavy applications, avoid the base configurations.
- Assuming identical battery health: Used second-generation models frequently suffer from degraded maximum battery capacity. Replacing an aging battery is affordable, but factor that cost into your initial purchase price.
Frequently Asked Questions
Can the 1st generation iPhone SE still be used as a daily driver?
It struggles heavily with modern app requirements, banking software compatibility, and battery longevity. It's best suited as a backup music player or emergency device rather than a primary smartphone.
Does the iPhone SE 3 support MagSafe charging?
No. None of the iPhone SE models feature built-in magnetic MagSafe rings on their rear glass, though you can buy third-party magnetic cases to achieve a similar effect.
Which model offers the best value for money today?
The third-generation model provides the best long-term value due to its inclusion of 5G, the powerful A15 chip, and extended software support windows. If budget is your absolute highest priority, a refurbished second-generation unit serves as a functional alternative for basic communication.
Are screen protectors and cases interchangeable between the 2nd and 3rd generations?
Yes. Because both phones share the exact same physical dimensions and layout, cases and screen protectors built for the 2020 model fit the 2022 model perfectly.
