  • Boost Your Battery and Make Your Phone Last Longer

    If you ask users how important battery life is, chances are it's pretty high on their list, especially with our phones becoming increasingly essential. They're our keys, wallet, map, mailing system, and...phone, so we need devices that go the distance.

    OPPO revolutionized charging tech with the dual-cell battery system introduced on the Reno4 Series. Using two batteries reduced the problem of overheating, which also meant there was no need to decrease voltage. Couple this with the wonders of the highly-optimized VOOCTM and SUPERVOOCTM Flash Charging, and users get superb battery life charged in minimal time spent.

    However, there are many ways to make your device more durable. So, if you want a phone battery that stays stronger for longer, strap in and discover these useful functions.

    All Aboard the Battery Health Engine

    Since its release in 2022, OPPO has featured the Battery Health Engine on more than a dozen smartphone products. But what exactly does it do?


    To put it simply, the engine sustains the battery lifespan of OPPO devices for much longer than the industry standard. It achieves this by solving issues with dead lithium, maintaining a battery capacity of 80% after more than four years of regular use! Let's not go into any more detail than that (because, frankly, this writer doesn't understand the internal wizardry), but rest assured, your devices will last much longer with this feature.

    Additionally, there's an eco-friendly element. The extended lifespan results in fewer cases of electronic waste from discarded smartphone batteries, which is beneficial for both people and our planet. It even won an award for its sustainability.

    Phone Manager

    So, your OPPO device is already built for longevity, but you can take it even further. Phone Manager is a handy tool to optimize your battery-saving with just a tap. Fewer charging cycles equals longer battery duration, after all.


    Go ahead and open the app and, from there, tap "Optimize." Phone Manager will conduct an automatic cleanup of your device, a security and privacy check, and other general to-dos. You can take full control of your apps, disallowing any auto-launches, as well as turning off background apps that guzzle a lot of power. All in all, it's a neat assistant that keeps your device nice and healthy, removing the pain of battery drain.

    Super Power Saving Bros

    If your device does get low, or you want to save some juice for later, you can activate Power Saving or Super Power Saving Mode. Particularly handy if you don't have a charger nearby.

    Head to "Settings" and then "Battery," and tap whichever mode you desire. Power Saving will reduce screen brightness, disable some background apps, and limit certain CPU functions to slow battery consumption. Super Power Saving will take it to the next level and limit your phone usage to six apps that you can select and add to the home screen. You can also manually adjust your battery settings to squeeze out as much staying power as possible. These functions are perfect for emergencies when you really need a phone or when you know you won't be active for a while (watching a movie or taking a meeting, for example).



    We know that when it comes to the dos and don'ts of batteries/charging, there's a lot of misinformation. Now, we're going to bust them open and separate the fact from the fiction.

    Does turning my phone off save battery life?

    Not really. With modern lithium-ion batteries, if your phone isn't in use, it has practically the same effect on longevity as if it were switched off. There really aren't many situations where it's necessary to power off your device completely.

    Does it damage the battery to leave your phone charging at 100%?

    Yes, kind of. Contrary to popular belief, once your phone hits 100%, it won't keep charging. It will simply wait until it drops to 99% and then charge back up again. However, it can be slightly damaging to battery lifespan because the charge level is so high. It's recommended to charge to between 20 and 80% to minimize battery damage—nothing a morning SUPERVOOCTM can't handle.

    On the other hand, does it damage the battery to let the phone die?

    Also yes. As mentioned, the best time to charge is during the medium state of battery loss, 20-80%. Letting the battery die completely causes a bit of extra damage, so try to avoid it. The good news is that with SUPERVOOCTM, even 5 minutes of charging is enough to juice up your device.

    But doesn't super fast charging greatly damage the battery?

    Not with SUPERVOOCTM, but for other chargers, it depends. Some third-party chargers may use improper voltage ranges, causing additional damage. But SUPERVOOCTM on OPPO devices is designed to work with the aforementioned dual-cell system, industry-leading components, and an intelligent charging algorithm to ensure speed and safety.

    Does temperature affect battery charging?

    Yes, if a phone gets too hot or cold, it can decrease charging speed and also damage long-term battery life. However, OPPO has made breakthroughs in extreme temperature charging, with the recent Reno11 Series able to charge even at -20°C (-4°F).*

    We hope we've provided useful battery tips and cleared up some FAQs. Now, you can discover OPPO's catalog of innovative devices, safe in the knowledge that they're built to last.
