As Apple continues to release new models each year, many users still rely on older iPhones like the iPhone 7 and iPhone 8. For those holding onto an iPhone 7, the question arises: is upgrading to the iPhone 8—released just one year later—still meaningful today? With both devices now several years old, the decision isn’t about cutting-edge features but rather practical longevity, software support, and daily usability. This article breaks down the key differences and evaluates whether making the switch makes sense in 2024.
Performance and Hardware Differences
The most significant upgrade from the iPhone 7 to the iPhone 8 lies under the hood. While both phones share a similar design language, their internal components tell a different story.
The iPhone 7 runs on the Apple A10 Fusion chip with 2GB of RAM, which was powerful in 2016 but struggles with modern apps and multitasking in 2024. The iPhone 8, released in 2017, features the more advanced A11 Bionic chip and also includes 2GB of RAM. Despite the same memory size, the A11 offers roughly 25–30% better CPU performance and a significantly improved GPU, enabling smoother app launches, better gaming, and faster responsiveness.
Additionally, the iPhone 8 supports wireless charging—a feature absent in the iPhone 7. While this may seem minor, it aligns the device with modern charging habits and eliminates wear on the Lightning port over time.
Camera Comparison: Subtle But Meaningful Upgrades
Both phones have a 12MP rear camera, but the iPhone 8 introduces improvements in image processing thanks to the A11 chip’s Neural Engine. This enables better noise reduction, enhanced dynamic range, and improved HDR performance, especially in low-light conditions.
The front-facing camera remains 7MP on both models, but the iPhone 8 benefits from better tone mapping and facial recognition tuning for selfies and FaceTime calls. Video recording is identical at 4K@30fps, but the iPhone 8 adds gyro-EIS (electronic image stabilization) for smoother handheld footage.

Battery Life and Charging Options
Battery degradation is a major concern for iPhone 7 owners by 2024. Original batteries in these devices are well beyond their 500-cycle lifespan, leading to reduced capacity and inconsistent performance. Even with a replacement, the iPhone 7’s modest 1960mAh battery limits screen-on time.
The iPhone 8 packs a slightly larger 1821mAh battery, but due to the more efficient A11 chip, delivers comparable or slightly better battery life. More importantly, it supports faster charging (with a compatible adapter) and Qi wireless charging—two conveniences that enhance long-term usability.
Durability and Design: Glass Back vs Aluminum
One visible change between the two models is the back material. The iPhone 7 uses aerospace-grade aluminum, making it durable and resistant to scratches. The iPhone 8, however, returns to a glass back to enable wireless charging. While glass looks more premium, it’s more prone to cracking if dropped.
Despite this, the iPhone 8’s glass is strengthened with ion-exchange technology and offers better water resistance (IP67 vs IP67—same rating, but Apple claims improved sealing). Both survive brief submersion in up to 1 meter of water for 30 minutes, but real-world tests suggest the iPhone 8 handles accidental spills slightly better.
| Feature | iPhone 7 | iPhone 8 |
|---|---|---|
| Processor | A10 Fusion | A11 Bionic |
| Rear Camera | 12MP, f/1.8 | 12MP, f/1.8 + improved processing |
| Front Camera | 7MP | 7MP, better low-light tuning |
| Battery Capacity | 1960 mAh | 1821 mAh (better efficiency) |
| Charging | Lights only | Lights + Wireless (Qi) |
| Water Resistance | IP67 | IP67 (improved seals) |
| iOS Support (Expected End) | Ended with iOS 16 | Likely through iOS 18 |
Software Support and Longevity in 2024
This is perhaps the most critical factor. As of 2024, the iPhone 7 no longer receives major iOS updates. It was dropped after iOS 16, meaning it lacks security patches, new features, and compatibility with updated apps that require newer OS versions.
In contrast, the iPhone 8 continues to receive iOS updates. Apple typically supports devices for five to six years, and the iPhone 8 is expected to be compatible with iOS 18—likely its final update. This means better app compatibility, access to modern privacy tools, and continued security maintenance.
Many banking, messaging, and productivity apps now require iOS 15 or higher. Users on outdated systems face increasing limitations—from being unable to log in to certain services to missing out on essential bug fixes.
Mini Case Study: Sarah’s Upgrade Dilemma
Sarah has used her iPhone 7 since 2017. By early 2023, she noticed apps crashing, slow Safari loading, and her bank app refusing to open. After replacing the battery, performance didn’t improve. She considered buying a used iPhone 8 for $120. Within a week of switching, her experience transformed: apps launched instantly, she could use Apple Pay without lag, and her phone received iOS 17 with critical security updates. For Sarah, the upgrade wasn’t about luxury—it restored basic functionality.
Is Upgrading Worth It in 2024?
If you're still using an iPhone 7, the short answer is yes—upgrading to an iPhone 8 is worthwhile, assuming you can find one in good condition at a reasonable price.
The iPhone 8 extends usable life by 1–2 years compared to the iPhone 7, primarily due to ongoing software support and superior hardware efficiency. It integrates better with modern ecosystems, supports newer accessories, and handles background tasks more reliably. For users on a tight budget who aren’t ready for a newer model like the iPhone SE (3rd gen) or iPhone 11, the iPhone 8 represents a smart middle ground.
However, if you’re considering spending over $150 on a used iPhone 8, it may be wiser to save a little more and invest in a newer device with longer support, such as the iPhone XR or iPhone 11, which offer larger screens, better cameras, and support through 2026 or beyond.
Checklist: Should You Upgrade from iPhone 7 to iPhone 8?
- ✅ Is your iPhone 7 running iOS 16 or earlier?
- ✅ Do apps frequently crash or fail to update?
- ✅ Is battery life below 80% health?
- ✅ Are you unable to use modern features like Apple Pay smoothly?
- ✅ Can you find an iPhone 8 for under $130 in good condition?
If you answered “yes” to three or more, upgrading is a logical step.
Frequently Asked Questions
Can the iPhone 8 still run modern apps in 2024?
Yes, the iPhone 8 handles most current apps well, including Instagram, Google Maps, and Zoom. However, some graphically intensive games or newer AI-powered tools may run slowly or not be supported.
Will the iPhone 8 get iOS 18?
Apple hasn't confirmed yet, but based on past patterns, the iPhone 8 is likely to receive iOS 18 as its final update. After that, it will stop receiving major updates, similar to the iPhone 7’s trajectory.
Is the iPhone 8 waterproof?
It has an IP67 rating, meaning it can survive immersion in up to 1 meter of water for 30 minutes. However, water resistance diminishes over time, especially if the device has been repaired or dropped.
Final Thoughts: Making a Practical Decision
Upgrading from the iPhone 7 to the iPhone 8 isn’t about chasing innovation—it’s about maintaining digital relevance. In 2024, staying connected means having a device that can securely run essential apps, receive updates, and keep up with daily demands without constant frustration.
The iPhone 8 may look nearly identical to the iPhone 7, but its internal upgrades deliver tangible benefits: longer software support, better performance, and modern charging options. For users clinging to a failing iPhone 7, even this small leap can restore peace of mind and extend smartphone usability into the next few years.
