We compare iPhone 16 and Galaxy S25 head-to-head, factoring in specs, resale value, and carrier trade-in deals to help you decide which upgrade is actually worth your money.
Overview
Are you staring at your old phone, wondering if 2025 is the year to finally upgrade? The iPhone 16 and Galaxy S25 are here, and both promise meaningful improvements. But with prices north of $1,000, the real question is: which upgrade delivers the best bang for your buck—not just today, but when you trade it in two years from now?
Background/Context
The smartphone market has matured. Annual upgrades now offer incremental gains rather than revolutionary leaps. Both Apple and Samsung are targeting users with phones that are three or more years old—people who will notice the jump in performance, camera quality, and battery life. But the decision isn't just about specs; it's about total cost of ownership, and that's where resale value and carrier trade-in promotions become critical.
We’ve spent weeks testing both devices, analyzing trade-in data from major carriers, and consulting industry resale charts. This isn’t a spec sheet comparison—we’re answering the question you actually came to ask: Which upgrade is worth it in 2025?
Core Concepts
What Makes an Upgrade Worth It?
An upgrade is “worth it” when the real-world benefits justify the out-of-pocket cost after trade-in. That calculation includes:
- Upfront discount – How much can you get for your old phone via carrier deals or trade-in programs?
- Long-term value – Which phone holds its value better when you sell it later?
- Feature improvements – Do the new camera, battery, and performance gains matter for your usage?
Why Resale Value Matters More Than Ever
With upgrade cycles stretching to four years, the phone you choose today will be your trade-in for the next model. Data from our Phone Resale Value Tracker shows that iPhones typically retain 15–20% more value after two years than comparable Galaxy phones. For example, an iPhone 15 Pro that cost $1,099 still fetches $600 after two years, while a Galaxy S24 Ultra ($1,299) drops to ~$550—a steeper depreciation curve.
In-Depth Analysis
iPhone 16: Key Upgrades
The iPhone 16 introduces the A18 Bionic chip, a 48MP Fusion camera system, and a new Capture Button for quick photo access. The base model starts at $999, with the Pro variants adding a 5x Telephoto lens and the A18 Pro chip. Battery life is up 4 hours over the iPhone 15 in our video streaming test. The biggest differentiator? Apple Intelligence features rolling out via iOS 18—on-device AI for photo editing, summarization, and Siri improvements.
Galaxy S25: Key Upgrades
The Galaxy S25 series features the Snapdragon 8 Gen 4 (custom for Galaxy), a 200MP main camera on the Ultra, and a brighter Dynamic AMOLED 2X display with 2,600 nits peak brightness. Samsung’s Galaxy AI gets upgrades like live translation and photo assist. The base S25 starts at $899, with the Ultra at $1,299. Battery life is similar to the S24, but charging speeds finally hit 45W on the Ultra (vs. 25W on the base S25).
Performance and Daily Use
In our benchmark tests, the iPhone 16’s A18 chip scores 15% higher single-core performance than the Galaxy S25’s Snapdragon. But in real-world app loading and multitasking, both feel identical. Gaming on the Galaxy S25 Ultra benefits from a faster GPU (ray tracing support), but the iPhone 16 Pro delivers smoother sustained performance due to better thermal design. If you’re a heavy gamer, consider the iPhone 16 Pro Max or Galaxy S25 Ultra.
Camera Comparison
iPhone 16’s computational photography excels in point-and-shoot scenarios—consistent colors, natural skin tones, and excellent low-light. The Galaxy S25 Ultra offers more versatility with its periscope zoom (10x optical) and high-res 200MP sensor for cropping. But Samsung’s processing can oversharpen. For social media sharing, the iPhone 16 photos require less editing. For travel photography with zoom, the Galaxy S25 Ultra wins. Check our Camera Shootout: iPhone 16 Pro vs Galaxy S25 Ultra for full samples.
Battery Life and Charging
iPhone 16: 3,561 mAh (Pro Max: 4,685 mAh). Galaxy S25: 4,000 mAh (Ultra: 5,000 mAh). In our standardized video loop test, the iPhone 16 lasted 18 hours, the Galaxy S25 17 hours. Real-world usage is comparable—both last a full day. Charging: iPhone 16 supports up to 27W wired (50% in 30 min), Galaxy S25 Ultra supports 45W (65% in 30 min). The Galaxy charges faster, but Apple’s MagSafe ecosystem adds convenience. If you value fast charging, the Galaxy S25 Ultra has the edge.
Practical Applications
Carrier Trade-In Deals – How to Maximize Value
Major carriers like Verizon, T-Mobile, and AT&T run aggressive trade-in promotions, but they often tie you to 36-month installment plans. Here’s what we’re seeing for the iPhone 16 and Galaxy S25:
- Verizon: Up to $1,000 off any iPhone 16 with eligible trade (iPhone 13 Pro or newer). For Galaxy S25, up to $800 off with trade of a Galaxy S23 or newer. The iPhone deal is stronger because the trade-in values are higher.
- T-Mobile: “Go5G Next” plan gives up to $1,000 off for either, but requires a premium plan. iPhone trade-in value is typically $50–$100 higher than Samsung’s.
- AT&T: Similar offers. Notably, AT&T sometimes offers a free base model with trade of any iPhone in good condition (even older ones) – check promo details.
Our advice: If you’re on a carrier that gives you $1,000 off an iPhone 16 with a trade that you’d get $600 for otherwise, the carrier deal makes the iPhone effectively $0 or very low cost. For the Galaxy S25, you might pay $200–$300 out of pocket. Over 36 months, that’s a difference of ~$6–$8/month – not huge, but the iPhone trade-in deal often offsets the higher initial price.
Resale Value After 2 Years
We analyzed data from Swappa, eBay, and our own marketplace to project resale values in early 2027. Assumptions: phone in good condition, no damage.
| Device | Launch Price | Projected Resale (2 years) | % Retained |
|---|---|---|---|
| iPhone 16 | $999 | $540 | 54% |
| Galaxy S25 | $899 | $395 | 44% |
| iPhone 16 Pro | $1,199 | $720 | 60% |
| Galaxy S25 Ultra | $1,299 | $680 | 52% |
Key takeaway: iPhones retain an average of 10–15% more value. If you plan to sell or trade in after two years, the iPhone 16 essentially costs less over its lifetime, even if the upfront price is higher.
Who Should Upgrade Now?
Upgrade to iPhone 16 if:
- You have an iPhone 13 or older – performance and camera leap are huge.
- You value long-term resale and carrier trade-in deals – Apple’s ecosystem keeps values high.
- You want the best point-and-shoot camera and reliable software updates for 5+ years.
Upgrade to Galaxy S25 if:
- You have a Galaxy S22 or older – the display, camera zoom, and AI features are a big step up.
- You need fast charging and prefer Android customization.
- You take lots of zoom photos or use DeX for desktop-like productivity.
Wait if:
- You have an iPhone 14/15 or Galaxy S23/24 – the upgrades are modest; wait another year.
- Your current phone still has a good trade-in value – check our Trade-In Calculator to see if you’re in a “sweet spot.”
Our Recommendations
After crunching the numbers, we favor the iPhone 16 for most people in the US due to stronger carrier deals and better resale value. The Galaxy S25 is a fantastic phone, especially the Ultra, but its depreciation hurts your next upgrade. If you’re loyal to Android or need the S Pen, the Galaxy S25 Ultra remains the best choice, but buy it with a trade-in promotion to soften the hit.
For budget-conscious buyers, consider the iPhone 14 Plus if you can find it discounted—it still offers great battery life and will be supported for years. Alternatively, the Galaxy S24 FE delivers core Galaxy AI features at a lower price.

## Bottom Line
The iPhone 16 wins on total cost of ownership thanks to stronger trade-in offers and higher resale value, making it the smarter upgrade for most people in 2025. However, if you prioritize camera zoom, fast charging, or the Android experience, the Galaxy S25 Ultra is worth the extra money—just be prepared for steeper depreciation.
