Display Comparison

Both devices share an 'Infinite' contrast ratio (nominal) and a sunlight contrast ratio of 4.087, suggesting similar outdoor visibility. However, the K12’s display specifications are not detailed, implying a lower-quality panel compared to the P20 Pro’s likely OLED display. The P20 Pro’s OLED technology offers superior blacks and color vibrancy, while the K12 likely uses an LCD, resulting in a less immersive viewing experience. The absence of refresh rate information for the K12 suggests a standard 60Hz panel, further differentiating it from potentially higher refresh rate options available in the P20 Pro’s era.

Camera Comparison

The Huawei P20 Pro’s camera system, while older, is likely more versatile and capable than the Lenovo K12’s. While specific details about the K12’s camera are missing, Huawei’s flagship history suggests a focus on image quality and features. The P20 Pro’s triple-lens setup, including a 40MP main sensor, likely delivers superior image detail, dynamic range, and low-light performance. The P20 Pro also benefits from advanced image processing algorithms and features like optical image stabilization (OIS), which are unlikely to be found on the K12. The K12 may include a macro lens, but these are often of limited utility.

Performance

The Kirin 970 (10nm) in the Huawei P20 Pro significantly outperforms the Qualcomm Snapdragon 460 (11nm) found in the Lenovo K12. The P20 Pro’s octa-core CPU, with 4x2.4 GHz Cortex-A73 cores, provides a substantial performance advantage over the K12’s 4x1.8 GHz Kryo 240 cores. This translates to faster app loading times, smoother multitasking, and a more responsive user interface on the P20 Pro. While the Snapdragon 460 is more power-efficient, the P20 Pro’s superior processing power is more impactful for demanding tasks. The P20 Pro’s GPU also offers a better gaming experience, though both phones will struggle with graphically intensive titles at high settings.

Battery Life

Both devices boast an endurance rating of 89 hours, indicating comparable battery life under similar usage conditions. However, the P20 Pro’s 22.5W wired charging is significantly faster than the K12’s 10W charging. The P20 Pro can achieve 58% charge in just 30 minutes, while the K12 will take considerably longer. The K12 does offer 2.5W reverse wired charging, a feature absent on the P20 Pro, allowing it to charge other devices, albeit slowly. The P20 Pro’s faster charging is a significant convenience factor, especially for users who frequently need to top up their battery.

Buying Guide

Buy the Lenovo K12 (China) if you need a functional smartphone for basic tasks like calling, texting, and light social media use, and your budget is under $100. Buy the Huawei P20 Pro if you prioritize smoother performance for multitasking and gaming, a more capable camera system, and a generally more premium user experience, even if it means spending more and accepting an older device.

Frequently Asked Questions

❓ Is the Huawei P20 Pro's battery still reliable after several years of use?
Battery degradation is a concern with older devices like the P20 Pro. While the initial endurance rating was 89 hours, the actual battery life will likely be reduced depending on usage patterns and charging habits. Replacing the battery is an option, but it adds to the overall cost.
❓ Will the Snapdragon 460 in the Lenovo K12 struggle with popular apps like TikTok or Instagram?
The Snapdragon 460 is a basic processor and may exhibit lag or slowdowns when running demanding apps like TikTok or Instagram, especially with multiple apps open simultaneously. It's suitable for light social media use, but not for intensive multitasking.
❓ Does the Huawei P20 Pro still receive security updates?
Huawei's software update situation is complex. While the P20 Pro initially received regular updates, support has likely diminished over time. Security vulnerabilities may remain unpatched, posing a potential risk. Users should exercise caution and consider the security implications of using an older device.
❓ Is the 2.5W reverse charging on the Lenovo K12 useful for anything?
The 2.5W reverse charging is extremely slow and primarily useful for emergency charging of very small devices like Bluetooth earbuds or a smartwatch. It's not practical for charging a smartphone or tablet.
