For millions of iPhone 7 Plus users still holding onto a device from 2016, the question isn’t just about whether to upgrade—it’s whether the jump to an iPhone 13 Pro justifies the change in size, cost, and design. The iPhone 7 Plus was a landmark phone: large, durable, with excellent battery life for its time and a beloved dual-camera system. But technology has evolved dramatically in seven years. The iPhone 13 Pro brings modern power, advanced cameras, and a sleeker form factor—but at nearly double the price and with a noticeably different footprint.
This isn't just a spec sheet battle. It's about real-world usability, longevity, and whether the physical changes—from screen size to weight to ergonomics—align with how you actually use your phone every day.
Design and Physical Differences: Bigger Isn’t Always Better
The most immediate difference between the iPhone 13 Pro and iPhone 7 Plus is their design language. The 7 Plus features thick bezels, a home button with Touch ID, and a more boxy aluminum body. In contrast, the 13 Pro has flat edges like its predecessor but with surgical-grade stainless steel, slimmer bezels, and a notch housing Face ID.
Despite both phones being labeled “Plus” or “Pro” sizes, their dimensions tell a nuanced story:
| Feature | iPhone 7 Plus | iPhone 13 Pro |
|---|---|---|
| Screen Size | 5.5 inches | 6.1 inches |
| Body Height | 158.2 mm | 146.7 mm |
| Width | 77.9 mm | 71.5 mm |
| Thickness | 7.3 mm | 7.65 mm |
| Weight | 188 grams | 204 grams |
| Display Type | LCD (Retina HD) | OLED (Super Retina XDR) |
| Water Resistance | IP67 (1m for 30 mins) | IP68 (6m for 30 mins) |
While the 13 Pro has a larger display, it’s actually shorter and narrower than the 7 Plus, making it slightly easier to grip despite the added heft from its stainless steel frame. The OLED screen delivers deeper blacks, higher brightness, and better outdoor visibility—critical improvements for media consumption and readability.
Performance Leap: From Capable to Cutting-Edge
The A15 Bionic chip in the iPhone 13 Pro is in a completely different league compared to the A10 Fusion in the 7 Plus. Apple claims up to 50% faster CPU performance and twice the graphics power. Real-world usage confirms this: apps launch instantly, multitasking is seamless, and demanding games like Resident Evil Village run smoothly at high settings.
But beyond raw speed, the 13 Pro includes 6GB of RAM versus the 7 Plus’s 3GB. This allows for better background app retention, faster switching, and future-proofing as iOS becomes more resource-intensive.
Consider this: the iPhone 7 Plus launched with iOS 10. It received updates through iOS 16—impressive support—but newer features like Live Text, Focus modes, and enhanced privacy tools are either limited or absent. The 13 Pro will likely receive updates until 2028 or beyond.
“Upgrading from a 2016 flagship to a 2021 model isn’t incremental—it’s generational. You’re not just getting a faster phone; you're gaining five years of technological progress.” — David Lin, Mobile Hardware Analyst at TechPulse
Camera Comparison: Night Mode, Telephoto, and Cinematic Video
The camera systems highlight perhaps the most dramatic evolution. The 7 Plus introduced portrait mode via its dual 12MP rear cameras—one wide, one telephoto. Impressive for its time, but today’s standards demand more.
The iPhone 13 Pro features three 12MP lenses: wide, ultra-wide, and telephoto—with sensor-shift stabilization on the main sensor. More importantly, it includes Night mode on all lenses, Photographic Styles, ProRes video recording, and Cinematic Mode, which applies real-time depth-of-field effects in videos.
- Night Photography: The 13 Pro captures usable images in near-darkness; the 7 Plus struggles without flash.
- Zoom Quality: The 13 Pro offers 3x optical zoom and up to 15x digital; the 7 Plus maxes out at 2x optical.
- Video: 4K Dolby Vision HDR at 60fps on the 13 Pro vs. 4K at 30fps on the 7 Plus.
If photography matters—even casually—the upgrade transforms what’s possible. Capturing sharp, well-lit photos in dim restaurants or shooting cinematic-looking videos for social media becomes effortless.
Mini Case Study: Sarah’s Upgrade Decision
Sarah had used her iPhone 7 Plus since 2017. As a freelance photographer assistant, she relied on her phone for client previews and quick edits. By 2023, she noticed delays in exporting photos, inconsistent autofocus in low light, and frustration when trying to record smooth b-roll.
After testing the iPhone 13 Pro at a store, she was struck by how quickly it processed RAW files, how stable the video was even while walking, and how much more natural skin tones looked in portraits. Despite the smaller physical height, she found the 13 Pro easier to handle thanks to its balanced weight distribution and improved grip.
She upgraded—and cut her editing time in half. For her, the size difference wasn’t a compromise; it was part of a more capable, professional toolset.
Battery Life and Charging: Efficiency Meets Modern Demands
Apple rates the iPhone 13 Pro for up to 22 hours of video playback; the 7 Plus manages around 14. In daily mixed use, the 13 Pro consistently lasts a full day and a half with moderate use, whereas the 7 Plus often needs midday charging.
Crucially, the 13 Pro supports MagSafe and Qi wireless charging, as well as faster wired charging (up to 50% in 30 minutes with a 20W adapter). The 7 Plus only supports slow wireless charging and peaks at 80% in an hour with standard charging.
However, if you’ve replaced your 7 Plus battery recently (post-2020 Apple battery program), you might still get decent life. But over time, older batteries degrade faster under modern app demands like GPS navigation, streaming, and background sync.
Is the Upgrade Worth It? A Practical Checklist
Deciding whether to upgrade should depend on your actual needs—not just specs. Use this checklist to evaluate your situation:
- Does your iPhone 7 Plus struggle to run current apps or games?
- Have you noticed longer load times, frequent crashes, or overheating?
- Do you take photos or videos regularly, especially in low light?
- Are you using an external battery pack because the built-in battery dies too fast?
- Do you want access to newer iOS features like Live Text, Focus Modes, or iCloud Shared Photo Library?
- Is repair cost approaching $100 (e.g., screen, battery, camera)?
- Do you plan to keep your phone for 3+ more years?
If you answered “yes” to three or more, the upgrade to the iPhone 13 Pro is likely justified—even with the shift in size and ergonomics.
Frequently Asked Questions
Will the iPhone 13 Pro feel too big or heavy compared to the 7 Plus?
Surprisingly, no. Although the 13 Pro is heavier (204g vs. 188g), its narrower width (71.5mm vs. 77.9mm) makes it easier to hold and operate with one hand. Many users report it feels more balanced despite the extra weight.
Can I expect significantly better battery life?
Yes. Even with a larger, brighter display, the A15 chip’s efficiency and larger battery capacity deliver 30–50% longer usage per charge under similar conditions. Standby performance is also vastly improved due to optimized background activity.
Is the price difference justified?
At launch, the 13 Pro started at $999; the 7 Plus was $769. Today, used 13 Pros start around $600–$700. If you value long-term reliability, camera quality, and software support, the investment pays off over 3–4 years. For casual users, a 13 or 14 might offer better value.
Final Verdict: Progress Over Nostalgia
The iPhone 7 Plus was a milestone device—well-built, reliable, and ahead of its time. But clinging to it in 2024 means missing out on advancements that fundamentally improve how we communicate, create, and stay productive.
The iPhone 13 Pro isn’t just bigger; it’s smarter, faster, and more capable across every metric. The size difference is minimal in practice, and the benefits—especially in camera, battery, and performance—are transformative.
Technology evolves not to make old things obsolete, but to enable new possibilities. Upgrading isn’t about discarding the past—it’s about embracing what your phone can now do that it couldn’t before.
