Oppo Reno 4 128GB Blue

It means the Oppo Reno Reno 3 is not a brand new phone, but a pre owned device that has been checked and prepared for resale. The phone goes through key functionality testing and an overall condition review, and if anything needs fixing, our refurbishment partners restore it so it works properly. It should be ready for everyday use, but we do not guarantee a like new appearance or that every internal part is an original manufacturer component. Because it has been refurbished, any original splash resistance the model may have had cannot be guaranteed.

To turn off the Oppo Reno 4, press and hold the Power button for a few seconds until the power menu appears, then tap “Power off”. If holding the Power button brings up a voice assistant or does not show the power menu after a software update, press and hold Power and Volume Up together, and then select “Power off” on the screen.

Oppo is a major Chinese technology company that designs and makes smartphones as well as other consumer electronics. Oppo phones are produced by OPPO itself, a global manufacturer known for its Reno and Find series and its ColorOS software. Oppo is also linked to a wider family of brands that includes names like OnePlus and realme, which is why you may hear people describe them as part of the same broader group, even though they operate as separate brands.

The Oppo Reno 4 is a 2020 model, so its current cost depends mostly on condition, storage version, and whether you buy it used or refurbished. In the refurbished market, the Reno 4 5G is often listed from around 200 euros, while used prices can vary widely based on wear, battery health, and included accessories. For context, the widely reported European launch price was about 325 euros, which is useful as a historical reference, but not what most people pay today.

Oppo phones come from China, as the Oppo brand was founded and is headquartered there. It is a Chinese electronics manufacturer that operates globally and sells its smartphones in many markets around the world, including Europe.

The easiest way to check battery health on an Oppo phone is through the settings, because newer versions of ColorOS include a dedicated section for it. Go to Settings, then Battery, and look for Battery health or Battery status, where you can see the health percentage and any recommendations. If you do not see it right away, open Settings, Battery, and look under additional or more battery settings, because on some versions it is placed there. You can also review charging protection and optimized charging features, which often provide useful hints about battery condition and daily usage habits.
