It’s funny how some tech, even when it’s nearly a decade old, still finds its way into our lives. The iPhone 6s and 6s Plus, released way back in 2015, are prime examples. You’ll still see them popping up in secondhand markets, serving as budget-friendly entry points into the Apple ecosystem, or even as trusty backup phones. While they share the same heart – that A9 chip, a 12MP camera, and Touch ID – and both eventually settled on iOS 15 as their final resting place, the most striking difference remains: their size. And that brings us to an age-old question, one that’s surprisingly relevant even now: does screen size truly dictate long-term usability?
Comfort vs. Capability: The Ergonomic Divide
The most obvious difference, of course, is how they feel in your hand. The iPhone 6s, measuring 138.3 x 67.1 x 7.1 mm and weighing a mere 143 grams, is designed for comfortable one-handed operation. It just fits. The 6s Plus, on the other hand, is a different beast entirely. At 158.2 x 77.9 x 7.3 mm and tipping the scales at 192 grams, it’s a significant step up. Trying to reach across that larger screen for a tap can feel like a stretch, especially when you’re on the go.
Both phones boast that familiar aerospace-grade aluminum body and glass front, which felt robust back in 2015. However, neither offers water resistance – a feature we’ve come to expect as standard today. So, a tumble onto concrete is still a gamble for either device.
If pocketability and ease of handling are your top priorities, the smaller 6s definitely wins. It’s simply more ergonomic, even in 2024. But the 6s Plus does have a trick up its sleeve: Reachability. While both phones support this feature (a quick double-tap of the Home button brings the top of the screen down), the larger display on the Plus means you’re less likely to need it as often. More content is visible at a glance, reducing the need for constant scrolling.
A Bigger Picture: Display and Media
When it comes to the screen itself, the 6s sports a 4.7-inch Retina HD display with a resolution of 1334 x 750 pixels. The 6s Plus steps it up to a 5.5-inch screen with a sharper 1920 x 1080 pixel resolution. Now, neither of these displays will blow you away with modern HDR or OLED tech, but the Plus model’s clarity is noticeably better. Reading e-books, browsing photos, or watching videos – it all looks a bit crisper on the larger screen.
For media consumption, that extra screen real estate really does make a difference. Watching YouTube on the 6s can feel a bit cramped, whereas the 6s Plus offers a more immersive, almost tablet-like experience, especially in landscape mode. Web browsing is also more comfortable; you’ll find yourself zooming out less to get a full view of a page.
As one human-computer interaction researcher pointed out, “Even on older hardware, display size directly influences user engagement. Larger screens reduce eye strain and improve readability over time.” It’s a simple truth that holds up, even for these older devices.
Performance and Software: The 2024 Reality
Here’s where things get a bit more uniform, and perhaps a little disappointing. Both the 6s and 6s Plus are powered by the same Apple A9 chip and 2GB of RAM. Back in 2015, this was a solid combination. Today? Well, it’s showing its age. Multitasking can be a struggle, and newer iOS updates are a no-go. Both models are capped at iOS 15.7.7, meaning they stopped receiving security updates in late 2023. This leaves them vulnerable to newer threats.
For basic tasks – calls, texts, emails, light web browsing – they’re still functional. But don’t expect lightning-fast app launches. Apps like Instagram, Chrome, or your banking platform will load slowly and might even crash if you push them too hard. Background app refresh is limited, and switching between apps often means they’ll reload from scratch.
Interestingly, despite the larger screen on the 6s Plus, there isn’t a significant performance gap between the two. Apple’s optimization was good enough that both feel similarly sluggish in 2024.
Battery Life: The Plus Pulls Ahead
This is where the 6s Plus really shines. It packs a 2915 mAh battery, a substantial upgrade from the 6s’s 1715 mAh. In practical terms, this means the Plus can genuinely last a full day with moderate use. The smaller 6s, especially with a battery that’s seen better days, often struggles to make it through.
If you’re using either of these phones daily in 2024, chances are the battery health is below 80%. Replacing the battery can help, but the quality of third-party replacements can vary. Even with a fresh battery, you’re likely looking at about 4–6 hours of screen time on the 6s, compared to a more respectable 7–9 hours on the 6s Plus.
Real-World Use: A Tale of Two Backups
I recall a friend, Sarah, who kept her iPhone 6s Plus as a backup after upgrading. When her primary phone died, she relied on the Plus for five days. She found the larger screen great for reviewing client emails and editing captions in Lightroom Mobile, though app launches were slow, and GPS took ages to lock on. She managed to get through full workdays only by dimming the screen and disabling background refresh. Her verdict? “It’s usable, but only if you accept serious limitations.”
Her husband, on the other hand, uses a 6s as his daily driver. The Plus is just too bulky for him. He sticks to calls, messaging, and occasional web searches. For him, the size is all about comfort, not enhanced functionality.
The Verdict: It's Still About Your Needs
So, in 2024, does size really matter between the iPhone 6s and 6s Plus? The answer, as always, is a resounding “it depends.” If you’re looking for a pocket-friendly device for basic communication and don’t mind the limitations of older hardware and software, the 6s is a solid, comfortable choice. But if you prioritize a better media experience, longer battery life, and don’t mind a larger footprint, the 6s Plus still offers a compelling, albeit dated, package. Both are a testament to Apple’s early design philosophy, offering a glimpse into a simpler smartphone era.
