Oppo K15s and K15x Launched with Up to 8,000mAh Battery, IP69K Durability, and 120Hz Displays

Following the domestic debut of its flagship Find X10 series, Oppo has expanded its endurance-focused lineup with the official launch of the Oppo K15s and Oppo K15x in China. Positioned to tackle battery anxiety and hardware longevity in the budget-to-midrange segment, the new pair introduces silicon-carbon power reserves reaching up to 8,000mAh, paired with industrial IP69K, IP69, IP68, and IP66 multi-tier durability ratings.

Engineered for users who spend long hours outdoors or work in physically demanding environments, both smartphones incorporate Oppo’s reinforced Diamond Anti-Drop Architecture alongside specialized touch digitization that allows responsive screen interactions with wet hands, oily fingers, or winter gloves up to 5mm thick.

Oppo K15s: 8,000mAh Capacity with IP69K Multi-Tier Protection

Leading the announcement is the Oppo K15s, which pushes battery endurance and environmental sealing benchmarks to new heights in the sub-2,000 yuan category:

• 8,000mAh 7-Year Long-Life Battery: The handset integrates an 8,000mAh high-density cell (rated at 7,820mAh) rated for over 2,000 charge-discharge cycles. Oppo notes that based on an average discharge cycle every 1.3 days, the battery will retain at least 80% usable health after seven years of regular use. The phone supports 45W SuperVOOC wired fast charging with low- and high-temperature protection.
• Full-Spectrum IP69K/IP69/IP68/IP66 Sealing: The K15s achieves an IP69K rating, allowing it to withstand high-pressure, high-temperature steam-jet washdowns, alongside continuous underwater submersion and fine sand ingress. It also clears 15 individual military-grade environmental tests under the GJB150A-2009 compliance standard.
• 6.57-Inch 120Hz OLED Flat Screen: The front is fitted with a 6.57-inch 1080P (FHD+) flat OLED display supporting a 120Hz refresh rate, 1.07 billion colors, and 100% DCI-P3 color gamut coverage.

Oppo has also baked in a dedicated High-Energy Outdoor Mode that boosts cellular transceiver power and dual-band GPS positioning accuracy.
• Optics & Connectivity: The rear camera island houses a 50MP main sensor with autofocus, 10x digital zoom, and dual-view recording, paired with an 8MP selfie shooter. Additional hardware features include full-scene NFC, an infrared blaster, two-wheeler EV smart pairing, Wi-Fi 5, and an in-display optical fingerprint scanner.
