For users still holding onto an iPhone X, the question isn’t just about desire—it’s about practicality. The iPhone X was a landmark device when it launched in 2017, introducing Face ID, edge-to-edge OLED displays, and a new design language. But nearly seven years later, technology has surged forward. Apple’s iPhone 13 Pro Max, released in 2021, represents a generational leap in almost every category. So, is upgrading from the iPhone X to the iPhone 13 Pro Max truly worth it today?
The answer depends on your usage, priorities, and expectations. This comparison dives deep into real-world performance, camera capabilities, battery life, software support, and long-term value to help you make an informed decision.
Performance: A Quantum Leap in Speed and Efficiency
The most dramatic difference between the iPhone X and the iPhone 13 Pro Max lies under the hood. The iPhone X runs on Apple’s A11 Bionic chip—a solid performer in its time but now significantly outpaced by modern standards. In contrast, the iPhone 13 Pro Max features the A15 Bionic chip with a 5-core GPU (in the Pro model), offering up to 50% faster graphics performance and vastly improved efficiency.
Real-world implications are clear: apps launch faster, multitasking is seamless, and demanding games like Genshin Impact or Minecraft RTX run smoothly at high frame rates. The iPhone X struggles with heavier apps today, often showing lag during transitions or prolonged use.
Additionally, the iPhone 13 Pro Max includes 6GB of RAM compared to the iPhone X’s 3GB. This extra memory allows for smoother background app retention and better handling of professional workflows like 4K video export or multi-layer photo editing.
Camera Comparison: Night Mode, Telephoto, and Cinematic Video
The camera evolution from the iPhone X to the iPhone 13 Pro Max is nothing short of revolutionary. While the iPhone X introduced Portrait mode and dual rear cameras (wide and telephoto), the 13 Pro Max expands on this with sensor-shift stabilization, Night mode on all lenses, macro photography, and ProRes video recording.
- Night Photography: The 13 Pro Max captures dramatically brighter, clearer low-light photos thanks to larger sensors and advanced computational photography.
- Telephoto Lens: Upgraded from 2x optical zoom to a sharper 3x system, ideal for portraits and distant subjects.
- Cinematic Mode: Introduced in iOS 15, this feature automatically shifts focus between subjects in videos—something the iPhone X cannot support.
- Photographic Styles: Allows real-time customization of color tone and contrast while preserving HDR data.
“Smartphone photography isn’t just about megapixels anymore—it’s about computational intelligence. The jump from iPhone X to 13 Pro Max is one of the most significant in Apple’s history.” — David Kim, Mobile Imaging Analyst at DXOMARK
Battery Life: From All-Day Anxiety to Multi-Day Confidence
Battery life is where many iPhone X users feel the pinch. With typical usage—messaging, social media, light browsing—the iPhone X often requires a midday charge. After years of battery degradation, even optimized settings may not extend life beyond 6–7 hours of screen-on time.
In contrast, the iPhone 13 Pro Max delivers up to 28 hours of video playback and consistently achieves 8–10 hours of screen time under mixed use. This means reliable all-day endurance, even with GPS navigation, streaming, or extended camera use.
The larger 4,352mAh battery, combined with the energy-efficient A15 chip and iOS 15+ optimizations, makes the 13 Pro Max one of the longest-lasting iPhones ever built.
Durability and Display: Glass, Brightness, and Longevity
Both phones feature glass front and back with stainless steel frames, but materials have evolved. The iPhone 13 Pro Max uses Apple’s Ceramic Shield front cover, which Apple claims offers four times better drop performance than the iPhone X’s glass.
The display is another major upgrade:
| Feature | iPhone X | iPhone 13 Pro Max |
|---|---|---|
| Display Size | 5.8 inches | 6.7 inches |
| Resolution | 2436 x 1125 | 2778 x 1284 |
| Brightness (HDR) | 625 nits | 1000 nits (1200 peak) |
| Refresh Rate | 60Hz | ProMotion 120Hz adaptive |
| Water Resistance | IP67 (1m for 30 mins) | IP68 (6m for 30 mins) |
The 120Hz ProMotion display on the 13 Pro Max makes scrolling, gaming, and animations noticeably smoother. It dynamically adjusts based on content, conserving battery when full speed isn’t needed. For anyone who spends hours reading, browsing, or watching videos, this is a game-changer.
Software Support and Future-Proofing
As of 2024, the iPhone X supports up to iOS 17—but likely won’t receive iOS 18. Apple typically provides five years of OS updates, and the iPhone X launched with iOS 11. Meanwhile, the iPhone 13 Pro Max will likely be supported through iOS 22 or beyond, meaning more years of security patches, new features, and app compatibility.
This longevity matters. Apps are increasingly optimized for newer hardware, and older devices face slower performance after major iOS updates. Users report noticeable lag on the iPhone X after updating to iOS 16 or 17, especially in Camera, Messages, and Safari.
Mini Case Study: Sarah’s Upgrade Experience
Sarah, a freelance photographer based in Portland, used her iPhone X for six years. “It held up well,” she said, “but editing RAW files became sluggish, and low-light shots were unusable without a tripod.” After switching to the iPhone 13 Pro Max, she noticed immediate improvements: faster export times, usable Night mode shots handheld, and the ability to shoot 4K Dolby Vision video for client reels. “It’s not just a phone—it’s a pocket studio now.”
Cost-Benefit Analysis: Is the Upgrade Justified?
The iPhone 13 Pro Max launched at $1,099, but as of 2024, refurbished models start around $650–$750. The iPhone X, if still functional, might fetch $100–$150 in trade-in value.
That puts the net upgrade cost at roughly $550. Consider what you’re gaining:
- 3+ years of future iOS support
- Dramatically better camera and video
- Twice the battery life
- Smaller, more efficient chip with superior thermal management
- Larger, smoother 120Hz display
Checklist: Should You Upgrade?
- ✅ Is your iPhone X showing signs of battery degradation (under 80% health)?
- ✅ Do apps or the OS feel sluggish, especially after updates?
- ✅ Are you missing features like Night mode, 4K video, or better zoom?
- ✅ Do you rely on your phone for work, content creation, or travel?
- ✅ Can you recoup value via trade-in or sell your current device?
If you answered yes to three or more, upgrading is likely worthwhile.
Frequently Asked Questions
Will my accessories work with the iPhone 13 Pro Max?
Most Lightning cables, AirPods, and wireless chargers are compatible. However, cases won’t fit due to size and camera layout differences. The 13 Pro Max is larger and heavier, so consider ergonomics if you prefer compact phones.
Can the iPhone 13 Pro Max last until 2027?
Yes. With expected support through iOS 22 (2028), regular battery replacements, and durable build quality, the 13 Pro Max is a 5–6 year device for most users.
Is the camera worth the upgrade alone?
If you value photography or create content, absolutely. The combination of sensor-shift stabilization, macro mode, Night mode on all lenses, and ProRes video makes this one of the best mobile imaging systems ever made.
Conclusion: Time to Move Forward
The iPhone X was groundbreaking in 2017, but technology waits for no device. Upgrading to the iPhone 13 Pro Max isn’t just about newer features—it’s about reclaiming speed, reliability, and creative freedom that aging hardware can no longer provide.
You’ll gain years of smoother performance, exceptional camera flexibility, and peace of mind knowing your phone will stay secure and supported. For long-time iPhone X users, this upgrade isn’t just justified—it’s overdue.
