Mid-range smartphone with 7000 mAh battery
OPPO Reno15 F impresses with its huge 7,000 mAh battery but still maintains an ultra-thin and light design and 120Hz AMOLED screen.
Are you someone who often has to travel on the road, or simply a genuine “cinephile” and tired of having to carry a heavy backup charger wherever you go?
The mid-range segment in early 2026 is witnessing a fierce race: How to fit a “huge” battery into a device that still has to be beautiful and thin?
The answer is called OPPO Reno15 F. The smartphone causes a fever not only because of OPPO’s signature shimmering appearance, but also because of its up to 7,000 mAh battery.

Design “deceives” the eye: 7,000 mAh battery but still extremely elegant
The first feeling when I held OPPO Reno15 F in my hand was surprise. Normally, smartphones with “huge” batteries often come with a thick and heavy appearance, but OPPO has done the opposite. The device is only 8.1mm thick and weighs 195g, ideal numbers for comfortable one-handed operation for long periods of time.
The rough aluminum back with a reflective “meteor shower” effect not only helps the device look luxurious but also minimizes fingerprints. In particular, being equipped with IP68/IP69 water resistance standards gives me complete peace of mind when accidentally encountering sudden rains or daily water spills.
Smooth screen and 7000mAh battery
The entertainment experience on Reno15 F is truly “cool” thanks to the 120Hz AMOLED panel. Every swipe from surfing Facebook to watching TikTok is smooth, with bright colors and high contrast. Although the brightness of 1400 nits is not the highest on the market today, the device still meets the needs of use in daylight.
The biggest selling point is definitely the 7,000 mAh battery. In a day of mixed use from checking email, taking photos to playing a few games, I used it from early morning until late at night and the device still had more than 40% battery left.
If you only use basic tasks, it is completely normal to last until the second day. When you need to recharge, VOOC 80W technology will help you recharge quickly, without having to wait too long.
Stable performance and intelligent ColorOS 16 operating system
Although the Snapdragon 6 Gen 1 chip is not the most powerful chip to “race for” performance points, in return, it operates extremely cool. Through testing with Lien Quan Mobile or PUBG Mobile, the device maintained a stable frame rate and the temperature was only around 33-34 degrees Celsius.
The real power of Reno15 F lies in the optimal capabilities of ColorOS 16. OPPO AI features such as smart object deletion or text summarization provide excellent support for work.
The 50MP camera that supports OIS anti-shake also helps me easily get sharp, colorful photos to post immediately on social networks without too much editing.
Who is OPPO Reno15 F for?
OPPO Reno15 F is suitable for those who need an “unbeatable” battery for high-intensity work, shippers, technology drivers or those who prioritize fashionable design and long-term stability.
However, if you are a professional gamer who only prioritizes the strongest configuration to play super heavy graphics games at max settings, high-end flagships will be a more suitable choice.
Currently, OPPO Reno15 F is being officially distributed at Minh Tuan Mobile with a price of only 11,990,000 with 0% installment incentives. The machine is always available with a full range of trendy color versions and a reputable warranty policy.
Conclusion: OPPO Reno15 F does not run in the pure configuration race but focuses on what users need most: Extremely strong battery in a beautiful design. This is definitely the most “practical” machine you can find right now.
