Iphone Xs Max Vs 6s Plus Is Upgrading Still Worth It In 2024

For users clinging to the iPhone 6s Plus in 2024, the question isn’t just about hardware—it’s about relevance. Apple stopped supporting iOS updates for the 6s line with iOS 15, meaning no security patches, app compatibility issues, and sluggish performance in modern apps. Meanwhile, the iPhone XS Max, released in 2018, supports up to iOS 17 and may even receive iOS 18. The gap between these devices spans six years of technological evolution. So, is making the jump from the 6s Plus to the XS Max still a worthwhile upgrade today? The answer depends on your needs, budget, and expectations.

Performance: A Quantum Leap in Speed and Efficiency

The iPhone 6s Plus runs on Apple’s A9 chip with 2GB of RAM. In 2015, it was powerful. In 2024, it struggles with multitasking, app launches, and even basic web browsing. Safari stutters on complex pages, and many newer apps either refuse to install or crash frequently. Background app refresh is nearly unusable, and switching between apps often results in reloads.

In contrast, the iPhone XS Max features the A12 Bionic chip—Apple’s first 7nm processor—with 4GB of RAM. It delivers significantly faster CPU and GPU performance, enabling smooth navigation, responsive gaming, and efficient photo and video editing. Apps open instantly, background processes remain stable, and augmented reality experiences run without lag.

Tip: If you're still using a 6s Plus, consider offloading unused apps to free up space and reduce system strain.

Display and Design: From Bezel-Heavy to Edge-to-Edge

The design language between these two phones couldn’t be more different. The 6s Plus sports thick bezels, a home button with Touch ID, and a 5.5-inch 750p LCD screen. While durable, the display feels outdated—colors lack vibrancy, brightness is limited, and viewing angles are mediocre.

The XS Max introduced Apple’s edge-to-edge Super Retina OLED display. Its 6.5-inch screen offers deeper blacks, richer colors, higher contrast (1,000,000:1), and true HDR support. Whether watching videos or editing photos, the visual upgrade is immediately noticeable. The stainless steel frame and glass back give it a premium feel, though it’s heavier and more prone to fingerprints than the aluminum 6s Plus.

Camera Comparison: Night Mode, Zoom, and Computational Photography

The 6s Plus has a 12MP rear camera and a 5MP front shooter. For its time, it delivered solid photos in daylight. But by 2024 standards, it lacks autofocus in low light, optical image stabilization, portrait mode, and any kind of night processing. Selfies are soft, and low-light shots are noisy and underexposed.

The XS Max brings dual 12MP cameras (wide and telephoto), enabling 2x optical zoom, improved low-light performance, and advanced Portrait Mode with depth control. Its Smart HDR and better sensor allow for more dynamic range and detail retention. While it doesn’t have Night Mode (introduced on iPhone 11), third-party apps and iOS 17 optimizations help extract usable images in dim lighting.

“Even without Night Mode, the XS Max captures twice as much light as the 6s Plus thanks to larger pixels and better software tuning.” — David Lin, Mobile Photographer & Tech Analyst

Battery Life and Charging: All-Day Use vs. Midday Anxiety

The 6s Plus had decent battery life in its prime, but after years of charging cycles, most units now last only 4–6 hours of screen-on time. It charges slowly via 5W adapter, and there’s no fast charging or wireless charging support—even with a Lightning cable upgrade.

The XS Max includes fast charging (up to 50% in 30 minutes with an 18W+ adapter) and Qi wireless charging. Apple rated it for up to 13 hours of video playback, and even in 2024, well-maintained units typically deliver 8–10 hours of screen time. This makes it far more reliable for daily use, especially with GPS, streaming, or social media.

Software Support and App Compatibility

This is where the 6s Plus truly falters. It maxes out at iOS 15, which means:

• No new features from iOS 16 or 17 (e.g., customizable lock screens, StandBy mode, enhanced privacy tools).
• Diminishing app support—many developers no longer optimize for older iOS versions.
• Security vulnerabilities remain unpatched, increasing risk over time.

The XS Max supports iOS 17 and is likely eligible for iOS 18, expected in late 2024. That means continued access to new features, security updates, and full compatibility with modern apps like TikTok, Instagram Reels, Google Maps Live View, and AI-powered tools.

Tip: Before upgrading, back up your 6s Plus data via iCloud or iTunes to ensure a seamless transfer.

Real-World Upgrade Scenario: Maria’s Experience

Maria, a teacher in Portland, used her 6s Plus for eight years. By early 2024, she noticed her phone couldn’t load school portals, failed to scan QR codes reliably, and died by noon. She upgraded to a refurbished XS Max for $220. Within days, she reported that Face ID was faster than Touch ID ever was, her classroom videos loaded instantly, and parents could finally see clear photos from school events. “It felt like going from dial-up to broadband,” she said. “I didn’t realize how much I was missing until I upgraded.”

Step-by-Step Guide: How to Make the Switch Smoothly

1. Back Up Your 6s Plus: Use iCloud (Settings > [Your Name] > iCloud > iCloud Backup) or connect to a computer and back up via iTunes/Finder.
2. Verify the Backup: Ensure photos, messages, and app data are included before proceeding.
3. Set Up Your XS Max: Power on, follow setup prompts, and choose “Restore from iCloud Backup” or “Restore from Mac/PC.”
4. Enable Face ID: Go to Settings > Face ID & Passcode to set it up during or after setup.
5. Update iOS: Install the latest version under Settings > General > Software Update.
6. Test Key Functions: Check camera, Wi-Fi, cellular data, and app logins to ensure everything transferred correctly.

FAQ Section

Can the iPhone XS Max still run modern games smoothly?

Yes. The A12 Bionic handles demanding titles like Genshin Impact and Call of Duty Mobile at medium settings. While not top-tier by 2024 flagship standards, it remains capable for casual and mid-core gaming.

Is the 6s Plus completely obsolete in 2024?

Functionally, yes—for most users. It can make calls and send texts, but web browsing, app usage, and security are compromised. It’s best suited as a backup phone or emergency device.

Should I consider a newer model instead of the XS Max?

If budget allows, iPhone 11 or newer offers Night Mode, better battery, and longer software support. But the XS Max remains a solid middle ground for those seeking a meaningful upgrade without paying flagship prices.

Final Verdict: Is the Upgrade Worth It?

Upgrading from the iPhone 6s Plus to the XS Max in 2024 is less about luxury and more about necessity. You’re not just gaining a better camera or screen—you’re regaining reliability, security, and access to the modern digital world. The performance leap alone transforms the user experience from frustrating to fluid.

The XS Max may lack some features found in newer iPhones, but for a used or refurbished price under $250, it delivers exceptional value. It supports current iOS versions, handles everyday tasks effortlessly, and looks and feels like a modern smartphone. For long-time 6s Plus users hesitant to let go, this upgrade is one of the most impactful they can make in 2024.
