The trendy 20:9, 6.5-inch FHD+ (1080 x 2400px) AMOLED screen is just a little shy of being called flagship-grade. It has the curves, it has the hertz but lacks the brightness. We managed to get 510 nits by cranking up the slider to maximum, and in Max Auto, the panel peaked at whopping 819 nits. This is more than enough for even the brightest conditions outside.
When it comes to color accuracy, the display's performance in this regard isn't stellar, but it's definitely within reasonable margins. At the default Vivid mode, the average dE2000 is 4.6 and switching to Gentle mode will decrease the average dE2000 deviation to 3.6. In both cases, however, the whites will appear a bit blue-ish.

Sadly, there's no HDR support as well. Oppo hasn't said anything about HDR compliance, and we've also tested YouTube and Netflix and can confirm that there's no HDR support of any sort.
The Reno3 Pro 5G doesn't boast exceptionally high battery capacity. In fact, it's just about the average you'd expect from a phone these days no matter if it's a midranger or a flagship. However, the results from our battery tests are far from average. The phone scored exactly 100h overall endurance rating with more than decent standby runtimes and excellent screen-on results on our web browsing and video playback tests.
We ran all the tests in its default 90Hz mode so switching over to 60Hz may give you some extra better battery life but we doubt it would be significant because Oppo will seamlessly switch down to 60Hz when high-refresh-rate is not needed.
Our battery tests were automated thanks to SmartViser, using its viSerDevice app. The endurance rating above denotes how long a single battery charge will last you if you use the Oppo Reno3 Pro 5G for an hour each of telephony, web browsing, and video playback daily. We've established this usage pattern so that our battery results are comparable across devices in the most common day-to-day tasks. The battery testing procedure is described in detail in case you're interested in the nitty-gritty. You can check out our complete battery test table, where you can see how all of the smartphones we've tested will compare under your own typical use.
Charging speeds are great as well. If you leave the phone with its 30W VOOC 4.0-compliant charger and cable for 30 minutes, you will get 72% charge from flat. Leaving it for another 18 minutes will ensure 100% charge, which is pretty impressive.
The phone offers a set of dual loudspeakers - one hiding behind the grille at the top bezel and one positioned right next to the USB-C port at the bottom. Loudness is above average, while sound quality is more than adequate. Of course, there's not much bass coming out from this tiny device, but vocals are crystal-clear without sounding muddy from the bass boost. We found the speakers good enough not only for listening to music but for videos and movies too.
Use the Playback controls to listen to the phone sample recordings (best use headphones). We measure the average loudness of the speakers in LUFS. A lower absolute value means a louder sound. A look at the frequency response chart will tell you how far off the ideal "0db" flat line is the reproduction of the bass, treble, and mid frequencies. You can add more phones to compare how they differ. The scores and ratings are not comparable with our older loudspeaker test. Learn more about how we test here.
We've recently discontinued our audio output quality test.
The reason for that is that most phones that arrived for testing were already excellent in this regard and whatever difference there was, it was marginal and probably indistinguishable to anything but our lab equipment.
