LaunchiPhoneNew models every year make many people feel like they are always behind others. However, if you are looking for a high-performance smartphone that still works well in 2025, the iPhone 12 series has proven to be a valuable and practical choice, especially when bought second-hand. This series still outperforms in terms of power, features, and long-term usability.
Here are 4 key reasons why the iPhone 12 remains a smart investment and why buying a second-hand iPhone fromCompAsia ThailandIt is the best way to get added value for your money.
1. Flagship-level performance with A14 Bionic chip
Apple's A14 Bionic chip, launched alongside the iPhone 12 lineup, is the world's first 5-nanometer smartphone processor. This chip set a new standard in speed, performance, and power management. Even in 2025, it continues to deliver a smooth user experience for everyday apps, content-heavy mobile games, augmented reality (AR) applications, and high-resolution video editing.
If compared to the latest mid-range smartphones on the marketiPhone 12 Pro MaxStill outperforms many other smartphone models in both processing speed and battery life. For users who prioritize reliable performance, a used iPhone 12 with the A14 chip is sufficient.
2. Timeless design with stunning display
The iPhone 12 is the first iPhone model to feature Apple's distinctive flat-edge design, a modern look that remains stylish and contemporary to this day. The entire series also comes with a Super Retina XDR OLED display that offers intense contrast, deep blacks, and realistic color accuracy.
Which means that even though it is second-hand, it still offers premium image quality whether you are streaming Netflix, editing photos, or using social media. And for those who prefer a larger screen, the iPhone 12 Pro Max features a spacious 6.7-inch display that is perfect for multitasking and immersive viewing.
Design is not just about aesthetics but also durability. The Ceramic Shield front cover improves impact resistance up to 4 times better than the previous model.
3. High-end features at a lower price
One advantage of choosing a refurbished iPhone 12 in 2025 is its value for money. Although the brand-new flagship model may cost up to 40,000 baht, a second-hand iPhone 12 Pro Max from CompAsia offers top-tier features at just a fraction of the original price.
