A New Generation of Smartphone Battery

Out of all the breakthroughs that take smartphones from one generation to the next, battery technology has been one of the slowest categories to progress.

Improving batteries involves complex physics, chemistry, and material science, making it a true frontier for any tech company. Since the invention of lithium batteries half a century ago, actual breakthroughs in battery technology have been limited.

With the rise of apps, network connections, and ever-larger screens, demands on smartphone batteries have skyrocketed. Five years ago, a big battery in a flagship phone was around 4000mAh–enough to last a full day back then–but today, that capacity just doesn't cut it.

OPPO has always been at the forefront of battery innovation, combining class-leading capacities and charging speeds in its smartphones. For Find X8 Series, this innovation is on another level, introducing cutting-edge silicon-carbon anode technology that marks a new chapter in battery capacity-to-size ratio, transforming the entire smartphone experience.

Higher Capacity; Smaller Size

In smartphone batteries, the anode material plays a critical role–it's the carrier for lithium ions and electrons during charging–making it the heart of energy storage and release. Traditional lithium-ion batteries rely on graphite for this, but silicon-carbon anodes offer a breakthrough, with over ten times the capacity of graphite. This means more energy in less space, unlocking the possibility for higher-capacity batteries that are lighter and slimmer.

At OPPO, we're constantly pushing for ways to increase silicon content to maximize energy density, and for Find X8 Series, we've achieved a new milestone by incorporating high-capacity, low-expansion silicon.

Advanced techniques like laser drilling and use of high-strength copper foil were also refined to further reduce the battery pack size, which combined with the breakthrough in silicon carbon, resulted in game-changing battery life gains for both Find X8 and Find X8 Pro.

For Find X8, the thickness of the battery pack drops from 5.87mm in the previous generation to just 5.1mm, allowing for a super-slim 7.85mm body. Despite this reduction in size, thanks to the breakthroughs made possible by the new silicon-carbon technology, the battery capacity of Find X8 increases from 5000mAh to 5630mAh, with an energy density of 819Wh/L (Typ). This is a remarkable 21% increase when compared with traditional solutions.

For Find X8 Pro, the larger size enabled us to push the battery capacity to an impressive 5910mAh, the largest in the Find Series phone. Yet, we maintained a sleek 8.24mm profile, overturning the status quo that a high-capacity, long-lasting battery can't be combined with an elegant, slim-designed smartphone.

Record-Breaking Battery Life with Lightning-Fast Charging

On a full charge, Find X8 and Find X8 Pro can stream videos for more than 20 hours, which equates to over 30 episodes of your favourite series on a single charge.

For a flagship like the Find Series, this kind of battery life isn't just convenient; it's essential, especially for creators who don't want to be weighed down by power banks. With Find X8 Pro, you can record Dolby Vision videos continuously for 7.2 hours. It's the kind of freedom that lets you create without limits, transforming the phone into a vlogging and content-capture system.

A cornerstone of a quality battery experience is fast charging, and Find X8 Series supports 80W SUPERVOOC fast charging and 50W AIRVOOC wireless charging, so you're always just a few minutes away from hours of extra uptime.

Alongside Find X8 and Find X8 Pro, OPPO is launching a bespoke magnetic mounting and charging system, including a magnetic case, a magnetic power bank and a new AIRVOOC 50W Magnetic Charger with a built-in fan. With it, you can enjoy the speed of AIRVOOC with the convenience of magnetic charging.

Steady and Enduring, Unfazed by Heat or Cold

Great technology shouldn't have limits, which is why Find X8 Series is tested in extreme climates to deliver optimal performance whatever adventures its users embark upon.

Picture this: it's -20°C, the freezing conditions are biting and even with your protective clothing, you're teeth are chattering and ears numbing. Find X8 Pro soldiers on, recording video for a solid 5.3 hours without faltering–and with the new Quick Button, you can even start and stop recording while wearing your winter gloves.

What about the other extreme? It's a scorching 35°C day in a rainforest–a once-in-a-lifetime trip–and Find X8 Pro doesn't break a sweat, recording continuously for 4.4 hours without dropping a frame or dimming the screen.

This level of performance far exceeds industry standards. So while not many smartphone makers push their products to such limits, OPPO tests to ensure its products, and in turn Find X8 Pro, won't hold you back on your next adventure.

And when the adventure of everyday life is in full swing, Find X8 Series provides a simple reassurance that your battery won't let you down. It means you can head out without a charger, capture moments, stream, game, connect, and stay fully immersed without a second thought, letting you enjoy life just a bit more freely and making each day feel a little lighter.
