Oppo has expanded its K-series smartphone lineup in China with the launch of the Oppo K15s and K15x, according to reports published by Gizmochina on Wednesday, Sept. 30, 2026, and covered by outlets including Ntvnews.id. The two mid-range devices join an existing portfolio that already includes the K15, K15 Pro, and K15 Pro+, arriving shortly after Oppo introduced its Find X10 lineup in the domestic market.
Oppo K15s Battery Capacity and Military-Grade Durability Standards
Positioned as the higher-end model of the two releases, the Oppo K15s centers its appeal around an 8,000mAh battery supporting 45W SuperVOOC fast charging and UFCS protocols. Gizmochina reported that Oppo claims the cell can endure more than 2,000 charging cycles while retaining at least 80 percent of its capacity after roughly seven years of simulated use. For physical protection, the K15s carries IP69K, IP69, IP68, and IP66 certifications and has passed 15 military-grade environmental tests under the GJB150A-2009 standard, as noted in the reporting from Ntvnews.id.
The device features a 6.57-inch AMOLED panel with a 2372 × 1080 FHD+ resolution, a 120Hz refresh rate, a peak brightness of 1,400 nits, and a 1,000Hz instantaneous touch sampling rate. The display supports 1,07 miliar warna and covers 100 percent of the DCI-P3 color gamut. Performance is driven by a MediaTek Dimensity 6360 Max processor paired with LPDDR4X RAM and UFS 2.2 storage, backed by a 4,300mm² vapor chamber cooling system.
Oppo K15s Camera Capabilities and Connectivity Features
Imaging on the K15s is handled by a 50-megapixel primary rear sensor equipped with autofocus and up to 10x digital zoom, alongside an 8-megapixel front-facing camera. Sourced specifications indicate the rear setup records video up to 1080p at 60fps and 720p slow-motion at 120fps. Connectivity options span NFC, an infrared blaster, dual-SIM support, Wi-Fi 5, and Bluetooth with LDAC and aptX HD codecs, while biometric security relies on an in-display optical fingerprint scanner.
Oppo K15x Specifications and Build Architecture
The more streamlined Oppo K15x features a 6,500mAh battery (listed with an actual capacity of 6,335mAh) that also supports 45W SuperVOOC and UFCS charging. Surabayainside.com notes that the handset is built around a 6.75-inch HD+ LCD screen with a 120Hz refresh rate, a peak brightness of 1,125 nits, and a 240Hz touch sampling rate. Under the hood, the K15x runs on a MediaTek Dimensity 6300 chipset with LPDDR4X RAM and UFS 2.2 storage.
To withstand drops, the K15x incorporates an IP64 rating and a diamond-structured anti-drop architecture. Its camera array is scaled down to a 13-megapixel rear autofocus sensor with 10x digital zoom and a 5-megapixel front shooter. While dropping NFC support found on the K15s, the K15x retains a 3,5mm headphone jack, expandable storage via a card slot, Wi-Fi 5, Bluetooth, dual-SIM capabilities, and a side-mounted fingerprint reader.
