Display Comparison

Both Fairphones utilize IPS LCD panels, prioritizing visibility and repairability over cutting-edge display technology. Specifics like resolution and refresh rate are similar, meaning the core viewing experience won't differ dramatically. However, the Fairphone 4 benefits from the more efficient Snapdragon 750G, potentially allowing for slightly better sustained brightness and color accuracy due to reduced thermal throttling during demanding tasks. The focus here isn't on visual fidelity, but on longevity and ease of replacement.

Camera Comparison

While both phones feature similar camera setups on paper, the image signal processor (ISP) within the Snapdragon 750G of the Fairphone 4 offers improved image processing capabilities. This results in better dynamic range, noise reduction, and overall image quality, especially in challenging lighting conditions. The Fairphone 4’s chipset allows for faster image capture and processing, reducing shutter lag. While neither phone boasts a flagship-level camera system, the 4 provides a more refined photographic experience.

Performance

The core difference lies in the chipsets. The Fairphone 3’s Qualcomm Snapdragon 632 (14nm) is a capable but aging processor. Its octa-core configuration (4x1.8 GHz Kryo 250 Gold & 4x1.8 GHz Kryo 250 Silver) is sufficient for basic tasks, but struggles with multitasking and demanding applications. The Fairphone 4’s Snapdragon 750G (8nm) is a significant upgrade. The 8nm process node is more efficient, leading to lower power consumption and reduced heat. The CPU configuration (2x2.2 GHz Kryo 570 & 6x1.8 GHz Kryo 570) provides a noticeable performance increase, particularly in single-core tasks. This translates to faster app loading times, smoother scrolling, and improved responsiveness. The 750G also includes an integrated 5G modem, a feature absent in the Fairphone 3.

Battery Life

The Fairphone 3 and 4 have similar battery capacities, meaning raw endurance won't differ drastically. However, the Fairphone 4’s more efficient Snapdragon 750G (8nm) consumes less power, potentially extending battery life during typical usage. Crucially, the Fairphone 4 supports 20W wired charging, allowing it to reach 50% charge in approximately 30 minutes. The Fairphone 3 lacks this fast-charging capability, requiring significantly longer to fully replenish its battery. This is a substantial convenience improvement for users who frequently need to top up their devices.

Buying Guide

Buy the Fairphone 3 if you prioritize the absolute lowest cost of entry into the Fairphone ecosystem and are comfortable with a more basic level of performance suitable for everyday tasks like calls, messaging, and light web browsing. Buy the Fairphone 4 if you value a smoother, more responsive user experience, 5G connectivity, faster charging, and a longer software support lifespan, even at a higher initial price point.

Frequently Asked Questions

❓ Will the Fairphone 4 receive more long-term software updates than the Fairphone 3?
Yes. Fairphone has committed to providing longer software support for the Fairphone 4, leveraging the newer chipset and its associated security features. This means you can expect more Android version updates and security patches over a longer period compared to the Fairphone 3.
❓ Is the performance increase from the Snapdragon 750G to the Snapdragon 632 noticeable in everyday use?
Absolutely. While both phones can handle basic tasks, the Snapdragon 750G in the Fairphone 4 provides a much smoother and more responsive experience when multitasking, browsing the web, or using demanding applications. The difference is particularly noticeable when switching between apps or playing graphically intensive games.
❓ Does the Fairphone 4's 5G connectivity require a new SIM card or plan?
Not necessarily. If your current SIM card and mobile plan already support 5G, you won't need to make any changes. However, to take advantage of 5G speeds, you'll need to be in an area with 5G coverage and have a 5G-compatible mobile plan.
❓ Is upgrading from the Fairphone 3 to the Fairphone 4 worth the cost if I'm happy with the current performance?
If you're content with the Fairphone 3's performance and don't require 5G connectivity or faster charging, the upgrade may not be essential. However, the Fairphone 4 offers a significant performance boost and longer software support, making it a worthwhile investment if you want a more future-proof and responsive device.
