Simulating a frequency of about one full cycle every 1.3 days, the battery capacity retention rate remains above 80% even after approximately 7 years of normal use. Combined with 45W super fast charging, officials claim it can achieve stable energy replenishment in both high and low temperature environments.
In terms of protection, K15s achieves a IP69K dust and water resistance level under controlled laboratory conditions, and supports multiple protection specifications of IP69K /69/68/66. It has also passed 15 military standard environmental tests under the GJB150A-2009 system. The body of the device adopts an ultra-durable diamond-like structure. Officials have also disclosed that K15s has passed a 72-month anti-aging test in a professional laboratory testing environment; the 6GB+128GB version is the model that passed the 60-month anti-aging test.
In terms of smoothness, the K15s is equipped with ultra-sensitive high refresh rates and supports touch operations in scenarios with wet hands, oily hands, and when wearing gloves (with a thickness not exceeding 5mm); the new model is powered by the Dimensity 6360 Max processor, uses LPDDR4X memory + UFS2.2 storage, and has been chip-level tuned by ColorOS.
