Display Comparison
Neither device boasts a flagship-level display, but details are lacking to make a direct comparison. However, the focus here is on internal components. We can assume both utilize IPS LCD panels given the price bracket. The absence of high refresh rate or LTPO technology suggests neither is geared towards demanding visual experiences.
Camera Comparison
Without detailed camera specs, a direct comparison is difficult. However, the chipset difference hints at superior image signal processing (ISP) capabilities within the Snapdragon 732G. Qualcomm’s ISPs are generally known for their robust noise reduction and dynamic range optimization. The Ulefone’s Helio G91, while capable, likely won’t match this level of refinement. The absence of information regarding sensor size and OIS makes it impossible to definitively declare a winner, but the Xiaomi has a processing advantage.
Performance
The core difference lies in the chipsets. The Xiaomi Redmi Note 12 Pro 4G’s Qualcomm Snapdragon 732G, fabricated on an 8nm process, offers a clear architectural advantage over the Ulefone Note 18 Pro’s Mediatek Helio G91 (12nm). The 8nm process inherently leads to better power efficiency and thermal management, meaning the Snapdragon 732G is likely to sustain peak performance for longer periods without throttling. While both CPUs feature a similar core configuration (2x high-performance & 6x efficiency cores), the Snapdragon’s Kryo 470 Gold cores, clocked at 2.2 GHz, have a slight edge over the Helio G91’s Cortex-A75 cores at 2.0 GHz. This translates to snappier app launches and smoother multitasking on the Xiaomi.
Battery Life
The Ulefone Note 18 Pro’s standout feature is its impressive 52:36h endurance rating. This suggests a significantly larger battery capacity than the Redmi Note 12 Pro 4G, although the exact mAh isn’t specified. However, this longevity comes at the cost of charging speed. The Ulefone is limited to 18W wired charging, meaning a full charge will take considerably longer than the Redmi Note 12 Pro 4G’s blazing-fast 67W charging. The Xiaomi can likely achieve a 0-100% charge in under 45 minutes, while the Ulefone will likely take well over two hours. This is a crucial trade-off: extended runtime versus rapid replenishment.
Buying Guide
Buy the Ulefone Note 18 Pro if you need a phone that can reliably last through heavy usage, travel frequently without easy access to power outlets, or simply dislike the anxiety of constantly monitoring battery percentages. Buy the Xiaomi Redmi Note 12 Pro 4G if you prefer the convenience of incredibly fast charging, value a more power-efficient processor for sustained performance, and are willing to trade some battery longevity for those benefits.
