OPPO K15x 5G Launched With 6,500mAh Battery, 120Hz Display and 45W Charging: Price, Specifications

Key Highlights

• OPPO K15x 5G launched in China alongside the OPPO K15s
• 6.75-inch HD+ LCD display with a 120Hz refresh rate
• MediaTek Dimensity 6300 chipset with 6GB RAM
• 6,500mAh battery with 45W SuperVOOC charging
• 13MP rear camera with up to 10x digital zoom

OPPO has officially launched the K15x 5G in China as a budget-focused smartphone with a large battery, 120Hz display and 5G connectivity. The phone was introduced alongside the OPPO K15s, making the two models part of the company’s latest K-series expansion in China.

The K15x is positioned below the K15s, with a lower price and simpler hardware. Its main highlights include a 6,500mAh battery, 45W SuperVOOC charging and a MediaTek Dimensity 6300 chipset. OPPO has not announced an India or global launch for the phone.

Design & Build

The OPPO K15x 5G measures approximately 8.61mm in thickness and weighs around 212 grams. The phone is available in Glacier White and Prism Purple colour options.

OPPO has also given the phone an IP64 rating, providing protection against dust and water splashes. The handset uses a side-mounted fingerprint sensor and retains a 3.5mm headphone jack, which is increasingly uncommon on smartphones in this segment.

The K15x also uses OPPO’s diamond anti-drop architecture, which is designed to improve resistance to accidental drops.

Display

The phone features a 6.75-inch LCD display with a 1570 × 720-pixel resolution and 120Hz refresh rate. Touch sampling goes up to 240Hz, while peak brightness is listed at up to 1,125 nits.

The 120Hz refresh rate should make scrolling and compatible animations appear smoother than a conventional 60Hz panel. However, the HD+ resolution is one of the compromises made to keep the K15x at a lower price.

For buyers who mainly browse social media, watch videos and use messaging apps, the large screen should be useful. Users who prioritise display sharpness may prefer phones with FHD+ panels.

Performance

The OPPO K15x is powered by the MediaTek Dimensity 6300, paired with 6GB of LPDDR4X RAM and up to 256GB of UFS 2.2 storage.

The Dimensity 6300 is a 5G-focused entry-level chipset, making the K15x suitable for everyday applications, streaming, social media and general multitasking. It is not positioned as a performance-focused gaming smartphone.

The supplied information also indicates storage expansion support, giving buyers another option if the 128GB or 256GB internal storage becomes insufficient.

Camera

The K15x has a 13MP autofocus rear camera with up to 10x digital zoom, along with a 5MP front camera. The rear camera can record video at up to 1080p/60fps according to current launch specifications.

The camera setup is fairly basic, reflecting the phone’s budget positioning. The 10x figure refers to digital zoom rather than optical zoom, so it should not be interpreted as providing the same image quality as a dedicated telephoto camera.

Battery & Charging

Battery life is one of the K15x’s main selling points.

The phone packs a 6,500mAh typical-capacity battery and supports 45W SuperVOOC and UFCS charging. The rated capacity is reported at 6,335mAh.

The large battery should give the phone more endurance than many conventional budget 5G smartphones, although actual runtime will depend on display brightness, network conditions, applications and usage patterns.

Software & Connectivity

The OPPO K15x runs Android 16 with ColorOS.

Connectivity includes 5G, Wi-Fi 5, Bluetooth and dual-SIM support. The phone also has a USB Type-C port and a 3.5mm headphone jack.

Unlike the K15s, the K15x does not include NFC, according to current specifications.

Price & Availability

The OPPO K15x 5G is officially available in China in two storage configurations:

The phone comes in Glacier White and Prism Purple. It is currently a China-market device, and OPPO has not announced India or global availability.

Competition & Alternatives

The K15x competes primarily with budget 5G smartphones where battery capacity and display refresh rate are important considerations.

For context, OPPO’s K13x 5G in India uses the same Dimensity 6300 platform but has a smaller 6,000mAh battery and 45W charging.

Pros & Cons

Pros

• 6,500mAh battery
• 45W fast charging
• 120Hz display
• Dimensity 6300 with 5G
• 3.5mm headphone jack
• IP64 protection
• Expandable storage

Cons

• HD+ rather than FHD+ display
• Basic 13MP + 5MP camera setup
• No NFC
• Only 6GB RAM

Final Verdict: Should You Buy It?

The OPPO K15x 5G is primarily designed for buyers who want a large battery and basic 5G hardware at a relatively low price. Its 6,500mAh battery, 45W charging and 120Hz display are the most relevant features for everyday users.

The compromises are equally clear: the display is HD+, the camera hardware is modest, and NFC is absent. Buyers looking for better photography or a sharper AMOLED screen should consider phones positioned above the K15x.

Best for: Budget buyers prioritising battery life, 5G connectivity and a large 120Hz display.

Consider alternatives if: You want an AMOLED/FHD+ display, stronger cameras or NFC.

Bottom line: The K15x is officially launched and available in China, but it should not currently be described as an India launch. Its 6,500mAh battery and 45W charging are the key reasons to consider it, while the HD+ LCD and basic camera system keep its positioning firmly in the budget segment.
