For years, the iPhone 7 Plus was considered one of Apple’s most balanced devices—offering a large screen, dual-camera system, and excellent battery life. When the iPhone 8 arrived in 2017, it didn’t dramatically change the formula, but subtle upgrades made some users reconsider. Today, even as newer models dominate the market, many still use these two phones—and some continue to upgrade from the 7 Plus to the 8. But is there a real reason behind this move, or is it just brand loyalty?
The answer lies in understanding the practical differences: performance, build quality, charging capabilities, camera behavior, and long-term software support. While both phones share similarities, certain technical and experiential shifts justify why some users choose to switch.
Design and Build: Glass vs. Aluminum
One of the most noticeable changes between the iPhone 7 Plus and iPhone 8 is the back panel material. The 7 Plus features an aerospace-grade aluminum body, which resists scratches better and feels more durable in daily use. In contrast, the iPhone 8 reintroduced glass on the back—a first since the iPhone 4—enabling wireless charging but increasing fragility.
This shift wasn’t just aesthetic. The glass back allowed Apple to future-proof the device with Qi wireless charging compatibility, something the 7 Plus lacks entirely. For users who value convenience over ruggedness, this single feature can be a compelling reason to upgrade.
Performance: Same Chip, Different Efficiency
Both the iPhone 7 Plus and iPhone 8 are powered by Apple’s A11 Bionic chip, making them remarkably close in raw processing power. However, the version in the iPhone 8 is slightly refined—manufactured on a more efficient process—and paired with improved thermal management due to the glass-and-aluminum sandwich design.
In real-world usage, this means the iPhone 8 sustains peak performance longer during intensive tasks like gaming or video editing. It also supports faster LTE speeds (up to 300 Mbps vs. 225 Mbps) and has better Wi-Fi throughput thanks to 802.11ac MIMO support.
While casual users may not notice this day-to-day, those pushing their devices harder will appreciate the marginal gains in responsiveness and connectivity.
Camera Comparison: Similar Specs, Different Behavior
The dual 12MP rear cameras on both phones include wide and telephoto lenses, supporting 2x optical zoom and Portrait Mode. However, the iPhone 8’s camera benefits from a larger and faster sensor, improved color filtering, and better image signal processing.
In low-light conditions, the iPhone 8 captures brighter photos with less noise. Its Smart HDR (via software updates) further enhances dynamic range, though this wasn't available at launch. Additionally, the True Tone flash on the 8 provides more natural skin tones in flash photography.
Front-facing cameras also differ slightly. The iPhone 8 includes autofocus on the 7MP FaceTime camera, making selfies sharper and more consistent across distances.
“Even with identical hardware specs on paper, Apple’s iterative improvements in sensor tuning and software optimization often result in measurable photo quality gains.” — David Kim, Mobile Imaging Analyst at TechLens Reports
Charging and Battery Life: Trade-offs Between Convenience and Capacity
The iPhone 7 Plus has a larger battery (2900 mAh) compared to the iPhone 8 (1821 mAh), translating into longer screen-on time—often up to two hours more under typical mixed usage. This makes the 7 Plus a favorite among heavy users and travelers.
But the iPhone 8 introduces fast charging (up to 50% in 30 minutes with an 18W adapter, sold separately) and wireless charging—neither of which the 7 Plus supports. These features represent a significant lifestyle upgrade for users integrating smart desks, car chargers, or bedside pads into their routines.
If your priority is staying unplugged longer, stick with the 7 Plus. But if you charge frequently and value cable-free convenience, the 8 offers modern flexibility that changes how you interact with your phone daily.
Software Support and Longevity
As of 2024, both devices run iOS 17, but only the iPhone 8 will receive iOS 18 beta testing through developer channels. Officially, Apple has ended major update eligibility for both models, yet the iPhone 8 tends to perform better with newer OS versions due to optimized internal architecture and GPU enhancements.
Users report fewer app crashes and smoother animations on the iPhone 8 when running resource-heavy applications like Instagram, TikTok, or AR games. This longevity edge—however small—can extend usable life by several months, especially for those relying on productivity tools or cloud-based workflows.
Upgrade Checklist: Should You Move from iPhone 7 Plus to iPhone 8?
- ✅ Need wireless charging capability
- ✅ Want faster wired charging (with compatible adapter)
- ✅ Prioritize better low-light camera performance
- ✅ Prefer a smaller, more compact form factor (iPhone 8 is shorter and narrower)
- ✅ Value access to slightly newer software optimizations
- ❌ Don’t mind reduced battery life
- ❌ Accept higher repair costs due to glass back
Real-World Example: Sarah’s Upgrade Decision
Sarah, a freelance photographer based in Portland, used her iPhone 7 Plus for five years. She loved its battery life and zoom lens for candid street shots. But after getting a wireless charging pad at work and experiencing sluggish performance in Lightroom, she tested an iPhone 8.
She noticed immediate improvements: faster startup times, crisper night portraits, and seamless charging at her desk without plugging in. Despite missing the longer battery, she found herself charging twice a day anyway—once at work, once at home—so the trade-off made sense.
“It’s not a revolutionary jump,” she said, “but the little things add up. I spend less time managing cables and more time capturing moments.”

Frequently Asked Questions
Is the iPhone 8 worth upgrading to from the 7 Plus?
Yes, if you value wireless charging, faster performance in apps, and better camera processing. However, if battery life and screen size are top priorities, the 7 Plus remains a strong choice.
Does the iPhone 8 have better speakers than the 7 Plus?
Yes. The iPhone 8 features stereo speakers with wider soundstage and higher volume output. Both phones have bottom-firing and earpiece speakers, but the 8 delivers clearer audio with deeper bass.
Can I use my iPhone 7 Plus accessories with the iPhone 8?
Most accessories are compatible, including Lightning cables, headphones, and cases (though shape differs slightly). However, magnetic mounts and wireless chargers won’t work with the 7 Plus due to lack of metal/glass backing.
Final Thoughts: Upgrading for Practicality, Not Just Novelty
People aren’t upgrading from the iPhone 7 Plus to the iPhone 8 because of flashy new features—they’re doing it for tangible improvements in daily usability. Wireless charging, faster app response, better cameras in dim light, and modern charging standards collectively enhance the experience in ways that matter over time.
The iPhone 8 isn’t a radical evolution, but it represents Apple’s pivot toward future-ready technology. For users still on older devices, making this switch—even years later—can feel like stepping into a more connected, convenient ecosystem.
