  • Snapdragon 8 Gen 2 provides flagship-level performance

  • Slower 100W charging (26 minutes to full)
  • OxygenOS, while clean, has seen changes in recent versions

Display Comparison

The OnePlus 12R boasts a measured peak brightness of 1181 nits, a strong figure ensuring excellent visibility even in direct sunlight. While the Redmi K70’s display specifications aren’t provided, it’s reasonable to expect a comparable brightness level given its flagship positioning. Both phones likely utilize AMOLED panels for vibrant colors and deep blacks. The absence of LTPO information for either device suggests they may not offer dynamically adaptive refresh rates, potentially impacting battery life during prolonged use at higher refresh rates. Bezels are likely similar, focusing on maximizing screen real estate.

Camera Comparison

Camera details are limited, but the focus should be on the main sensor performance. Without specific sensor size or aperture information, it’s difficult to definitively declare a winner. The absence of details suggests neither phone prioritizes a groundbreaking camera system, focusing instead on delivering a solid, all-around imaging experience. We can assume both will offer standard features like HDR and night mode, but image processing styles will likely differ, impacting color science and dynamic range.

Performance

Both the Redmi K70 and OnePlus 12R are powered by the Qualcomm SM8550-AB Snapdragon 8 Gen 2 (4 nm) chipset, featuring an identical CPU configuration: 1x3.2 GHz Cortex-X3, 2x2.8 GHz Cortex-A715, 2x2.8 GHz Cortex-A710, and 3x2.0 GHz Cortex-A510. This means raw processing power will be nearly indistinguishable between the two. The 4nm fabrication process ensures excellent thermal efficiency, minimizing throttling during sustained workloads like gaming. However, the effectiveness of each phone’s cooling solution (not specified) will ultimately determine real-world sustained performance. RAM specifications are missing, but both are expected to utilize LPDDR5x for fast memory access.

Battery Life

The OnePlus 12R shines with an active use battery score of 14:32h, indicating exceptional endurance. The Redmi K70’s battery capacity is not specified, but its 120W wired charging is a significant advantage. The OnePlus 12R’s 100W charging takes 26 minutes to reach 100%, while the Redmi K70 achieves the same in just 18 minutes. This 8-minute difference is substantial for users who frequently need to top up their battery quickly. The faster charging of the K70 effectively mitigates any potential disadvantage from a slightly smaller battery capacity.

Buying Guide

Buy the Xiaomi Redmi K70 if you need the fastest possible charging speeds and appreciate a phone that can fully replenish its battery in under 20 minutes. Buy the OnePlus 12R if you prioritize maximizing battery life and prefer a longer-lasting device between charges, even if it means a slower charging cycle. Both are excellent choices for gamers and power users.

Frequently Asked Questions

❓ Will the Snapdragon 8 Gen 2 in either phone struggle with demanding games like Genshin Impact?
No, the Snapdragon 8 Gen 2 is a powerhouse chipset capable of handling even the most graphically intensive games. Both the Redmi K70 and OnePlus 12R should deliver a smooth gaming experience, though sustained performance will depend on the effectiveness of each phone’s cooling system.
❓ Is the 100W charging on the OnePlus 12R still considered fast compared to other phones?
Yes, 100W charging is exceptionally fast and significantly quicker than the standard 25W or 45W charging found on many smartphones. While the Redmi K70’s 120W is faster, the OnePlus 12R’s charging speed is still highly competitive and will replenish the battery in a reasonable timeframe.
❓ Does either phone support wireless charging?
The provided specifications do not mention wireless charging support for either the Redmi K70 or the OnePlus 12R. It's likely neither phone includes this feature, as it's often omitted in devices prioritizing fast wired charging.
