September 2014 was weird. Honestly, if you weren’t there, it’s hard to describe the sheer level of anxiety people had about the size of their pants. For years, Steve Jobs had basically preached from the mountaintop that 3.5 inches was the "goldilocks" zone for a phone. Then Tim Cook walked onto the stage at the Flint Center—the same place the original Mac was unveiled—and dropped the iPhone 6 and iPhone 6 Plus.
It changed everything.
It wasn't just a bigger screen; it was a total admission that the Android world was onto something. Samsung had been eating Apple’s lunch with the Note series, and Apple finally stopped pretending people didn't want giant displays. But looking back at these devices now, through the lens of a decade of evolution, they represent both Apple's greatest triumph and its most public engineering faceplant.
The Big Screen Shift: Why iPhone 6 and iPhone 6 Plus Mattered
Let's talk about that 5.5-inch monster.
The iPhone 6 Plus was massive for its time. Today, we carry around Pro Max models without thinking twice, but in 2014, the Plus felt like holding a surfboard to your ear. It wasn't just about the real estate, though. Apple introduced "Reachability," that little double-tap on the home button that slid the screen down so your thumb could actually reach the top icons. It was a clever, somewhat clunky band-aid for a problem Apple created by supersizing the hardware.
The standard iPhone 6, with its 4.7-inch display, became the immediate "default" phone for millions. It felt thin. Ridiculously thin. At 6.9mm, it’s still one of the slimmest iPhones ever made. That slimness came at a price, specifically that polarizing "camera bump" that prevented the phone from laying flat on a table. We’re used to it now—modern camera islands are basically mountains—but back then, people lost their minds over it.

The "Bendgate" Reality Check
You can't talk about the iPhone 6 and iPhone 6 Plus without mentioning the structural elephant in the room.
Lewis Hilsenteger from Unbox Therapy posted a video that basically broke the internet. He bent an iPhone 6 Plus with his bare hands. Suddenly, everyone was terrified that sitting down with a phone in their back pocket would turn their $750 investment into a piece of modern art. Apple officially claimed only nine customers complained about bending in the first week, but the internal documents revealed during a 2018 lawsuit told a different story.
Apple knew.
Internal testing showed the iPhone 6 was 3.3 times more likely to bend than the 5s, and the Plus was 7.2 times more likely. They eventually quietly reinforced the chassis with a stronger aluminum alloy (7000 series) in the 6s, but for the original 6 owners, the "Touch Disease" was the real lingering nightmare. This happened because the logic board would slightly flex, eventually loosening the Touch IC chips. Your screen would start flickering with a gray bar at the top, and then—boom—touch functionality was gone.
Performance: The A8 Chip and the 1GB RAM Bottleneck
Under the hood, both the iPhone 6 and iPhone 6 Plus ran the A8 chip. It was a 20nm process, which was a big deal for efficiency. But Apple made a choice that would haunt the longevity of these devices: they stuck with 1GB of RAM.
Even at launch, tech enthusiasts were skeptical.

The iPhone 6 Plus had to push a lot more pixels than the standard 6 (1920x1080 vs 1334x750). Because the RAM was so limited, the Plus often struggled with UI lag that the smaller model avoided. If you tried to keep too many Safari tabs open, the phone would constantly reload them. It’s the primary reason these phones felt "old" much faster than the iPhone 5s or the later iPhone 6s. While the 5s was a marathon runner, the 6 was more of a sprinter that ran out of breath by iOS 11.
Why the Camera Was a Secret Game Changer
Forget the megapixels for a second. The iPhone 6 stuck with 8MP, which sounds ancient now. However, it introduced "Focus Pixels." This was Apple’s marketing term for phase-detection-autofocus. It meant the phone could focus almost instantly, a massive jump over the "hunt and peck" contrast-detection systems of the past.
The iPhone 6 Plus had one major advantage over its smaller sibling: Optical Image Stabilization (OIS).
- iPhone 6: Used digital "Cinematic Image Stabilization."
- iPhone 6 Plus: Had a physical floating lens element to cancel out hand tremors.
This made a massive difference in low light. The Plus could keep the shutter open longer without blurring the shot. It was the first time Apple really gave us a reason to buy the "big" phone other than just screen size. If you wanted the best camera, you had to go big.
The Legacy of the Design Language
Look at an iPhone 15 or 16 today. Notice the slightly rounded edges? That DNA started right here. After years of the flat, industrial "sandwich" design of the 4 and 5, the iPhone 6 brought in the era of the rounded aluminum unibody. It felt like a smooth pebble in your hand.
It was also the birth of Apple Pay.
The iPhone 6 was the first to include an NFC chip, though it was locked down tighter than Fort Knox. You couldn't use it for anything except Apple's own payment system. It felt futuristic to tap your phone at a Walgreens and walk out, even if half the cashiers didn't know how it worked yet. It was the beginning of the end for the physical wallet.
What Most People Get Wrong About the 6 Plus
A lot of folks think the 6 Plus was just a "bigger iPhone 6." That’s not quite right. It was actually the first time Apple tried to bridge the gap between a phone and an iPad.
Landscape mode on the 6 Plus was unique. You could turn the phone sideways on the home screen and the icons would rotate. In the Mail or Messages app, you’d get a split-pane view—inbox on the left, content on the right. Apple eventually killed this off in later iOS versions for most models, which is a shame. It genuinely made the "Plus" feel like a productivity tool rather than just a large window for Netflix.

Real-World Longevity and the iOS 13 Cutoff
The iPhone 6 and 6 Plus finally hit the end of the road with iOS 13. When that update dropped in 2019, the 6 series was left behind while the 6s lived on for years. This reinforced the idea that the 6 was a "transitional" device. It was the hardware jump everyone wanted, but it lacked the internal headroom to stay relevant in a world of increasingly heavy apps.
If you find one in a drawer today, it’s probably a sluggish experience. But for its time, it was the most successful iPhone launch in history. Apple sold 10 million units in the first weekend. Think about that. Ten million people in three days.
Actionable Takeaways for Collectors or Legacy Users
If you are still holding onto an iPhone 6 or considering buying one for a child or as a "distraction-free" device, keep these specific points in mind:
- Check the Battery Health: These models are notorious for "throttling" performance when the battery degrades. A $30 battery swap can make a dead iPhone 6 feel twice as fast.
- Stick to iOS 10 or 11 if possible: If you happen to find one that hasn't been updated to iOS 12.5.7, keep it there. The older operating systems are much lighter on the 1GB of RAM.
- The "Touch Disease" Test: If you're buying a used one, press firmly (but carefully) on the top area of the screen near the earpiece. If the screen glitches or touch stops working, the logic board is failing. Walk away.
- Security Limits: Since it can't run modern iOS versions, it doesn't get the latest security patches. Don't use an iPhone 6 for your primary banking or sensitive work emails. Use it for music, basic texting, or as a dedicated GPS for the car.
- Storage Constraints: The 16GB base model was a crime even in 2014. If you're looking for a legacy device, hunt for the 64GB or 128GB versions. 16GB is essentially full after the OS and three apps are installed.
The iPhone 6 and iPhone 6 Plus were the devices that proved Apple could listen to the market. They weren't perfect—far from it—but they set the stage for the massive, powerful, and durable slabs we carry today. They were the growing pains of the modern smartphone.
