Purchasing an iPhone XS or XS Max in 2025 may seem like a step back in time, but for budget-conscious buyers or those who prefer compact iOS devices, these models still hold relevance. Released in 2018, both phones were flagship devices in Apple’s lineup and share nearly identical internals. However, their differences—especially in display size, battery life, and ergonomics—can significantly impact daily use. With newer models dominating the market, deciding between the XS and XS Max requires careful consideration of your priorities: portability versus screen real estate, longevity expectations, and software support.
While neither device receives major iOS updates beyond iOS 16 (with security patches possibly trickling into early 2025), they remain functional for basic tasks, light photography, and everyday communication. This guide breaks down the key factors to help you determine which model better suits your needs this year.
Design and Display: Size Matters More Than You Think
The most noticeable difference between the iPhone XS and XS Max is size. The XS features a 5.8-inch Super Retina OLED display, while the XS Max expands that to 6.5 inches—an increase that affects more than just media consumption.
The XS is notably more compact and easier to operate with one hand. It weighs 177 grams and measures 143.6 x 70.9 x 7.7 mm, making it one of the last smaller iPhones Apple produced before shifting toward larger designs. In contrast, the XS Max weighs 208 grams and measures 157.5 x 77.4 x 7.7 mm, placing it firmly in the “phablet” category.
Both devices feature the same OLED panel technology, offering deep blacks, vibrant colors, and excellent contrast. Resolution differs slightly: the XS has a 2436 x 1125 pixel display (~458 ppi), while the XS Max boasts 2688 x 1242 pixels (~456 ppi). In practical terms, both look sharp, but the larger screen enhances video viewing, gaming, and multitasking.
Performance and Software Longevity
Under the hood, both phones are powered by Apple’s A12 Bionic chip—a six-core processor with second-generation neural engine. For 2018, it was groundbreaking; by 2025 standards, it's outdated but not obsolete.
The A12 still handles core functions like web browsing, messaging, email, and social media apps reasonably well. Light photo editing and older games run smoothly, though newer titles or demanding applications will show lag. Camera processing and app launches are snappy compared to many mid-tier Androids from the same era.
Critically, Apple ended major iOS version support for these models with iOS 16, released in 2022. While limited security updates may continue through early 2025, don’t expect new features or compatibility with future app updates. Many developers are already optimizing for A13 and newer chips, meaning some apps may slow down or stop supporting these devices entirely.
“Even without new iOS features, the A12 remains impressively efficient. But by 2025, users should expect diminishing returns in speed and compatibility.” — David Lin, Mobile Hardware Analyst at TechPulse Weekly
Camera Comparison: Nearly Identical, But Not Equal
Both the iPhone XS and XS Max sport dual 12MP rear cameras: a wide lens (f/1.8) and a telephoto lens (f/2.4), capable of 2x optical zoom and up to 10x digital zoom. Front-facing cameras are also identical: 7MP TrueDepth with Portrait Mode and Animoji support.
In real-world conditions, image quality is nearly indistinguishable between the two. Low-light performance, dynamic range, and color accuracy are strong for their generation, especially when using Smart HDR. Video recording tops out at 4K at 60fps with extended dynamic range and stereo audio.
However, there is one subtle advantage: the XS Max tends to deliver slightly more consistent stabilization during video capture due to marginally better thermal management from its larger chassis. This doesn’t mean the XS performs poorly—it doesn’t—but prolonged recording sessions may lead to minor frame drops or warming on the smaller model.
| Feature | iPhone XS | iPhone XS Max |
|---|---|---|
| Display Size | 5.8 inches | 6.5 inches |
| Battery Life (Video Playback) | Up to 14 hours | Up to 15 hours |
| Weight | 177g | 208g |
| Rear Cameras | Dual 12MP | Dual 12MP |
| Fingerprint ID? | No | No |
| Face ID | Yes | Yes |
| iOS Support Status (2025) | Limited (up to iOS 16) | Limited (up to iOS 16) |
Battery Life and Daily Usability
Battery life is where the XS Max pulls ahead. Apple rated the XS for up to 14 hours of video playback, while the XS Max reaches 15 hours. Real-world usage shows a more significant gap: the XS typically lasts a full day with moderate use, but heavy users may need a recharge by late afternoon. The XS Max, thanks to its larger 3,174mAh battery (vs. 2,658mAh in the XS), often stretches into a second day under light conditions.
If you're someone who travels frequently, dislikes carrying chargers, or uses GPS navigation regularly, the extra endurance of the XS Max becomes a tangible benefit. Both support fast charging (50% in 30 minutes with 18W adapter, sold separately) and Qi wireless charging, so power options are identical.
Mini Case Study: Sarah’s Upgrade Dilemma
Sarah, a freelance writer in Portland, wanted an affordable iPhone in early 2024. Her old iPhone 8 was slowing down, but she didn’t want to spend over $700 on a new model. After researching, she found used iPhone XS units selling for around $220 and XS Max models for $260.
She initially leaned toward the XS for its size, but after testing both in-store, she realized the XS Max made reading manuscripts and editing on Pages far more comfortable. She also appreciated the longer battery life during coffee shop work sessions. Though heavier, she adapted quickly and now considers the trade-off worth it.
Her advice? “Try holding both. Specs don’t tell the whole story—how it feels in your hand matters just as much.”
Checklist: What to Evaluate Before Buying
- Assess battery health: Check if the device has >80% maximum capacity (Settings > Battery > Battery Health).
- Verify iCloud lock status: Ensure the phone isn’t Activation Locked to a previous owner.
- Test Face ID: Confirm it unlocks reliably in different lighting conditions.
- Inspect screen and body: Look for scratches, burn-in (common in older OLEDs), or water damage indicators.
- Confirm iOS version: Make sure it runs at least iOS 16.7 or later for latest security fixes.
- Consider accessories: Availability of cases and screen protectors may be limited in 2025.
FAQ
Can the iPhone XS or XS Max run iOS 17 or iOS 18?
No. Apple officially discontinued iOS update support for the XS and XS Max with iOS 16. While minor security patches may appear into early 2025, no new operating system versions will be compatible.
Is the iPhone XS Max waterproof?
Yes, both models have an IP68 rating, meaning they can survive submersion in up to 2 meters of water for 30 minutes. However, water resistance degrades over time, especially on devices from 2018.
Which one holds resale value better?
Historically, the XS Max held value slightly better due to higher initial demand and larger-screen appeal. However, by 2025, depreciation has largely equalized both models, with condition being the primary factor in resale pricing.
Final Recommendation: Who Should Buy Which?
The choice ultimately comes down to lifestyle and usage patterns.
The iPhone XS is ideal for users who:
- Prefer a compact, lightweight device
- Use their phone one-handed frequently
- Want a secondary or travel phone
- Are on a tight budget and find a good-condition XS significantly cheaper
The iPhone XS Max suits those who:
- Watch videos, read, or game on their phone regularly
- Need longer battery life between charges
- Have larger hands or don’t mind a bulkier device
- Want the best possible experience from an older iPhone without upgrading to modern edge-to-edge models
Conclusion
In 2025, choosing between the iPhone XS and XS Max isn’t about cutting-edge performance—it’s about balancing form, function, and affordability. While neither phone is future-proof, both can serve as reliable tools for calls, messages, light productivity, and photography, provided you accept their limitations. The XS wins on portability; the XS Max delivers in screen space and stamina.
