Oppo Find X8 Ultra review

Display

The Oppo Find X8 Ultra packs a 6.82-inch LTPO OLED display with a 1,440x3,168px resolution or 510ppi density. It supports dynamic 120Hz refresh rate, 240Hz touch sampling, 2160Hz PWM dimming, true tone adjustments, and all sorts of HDR - HDR Vivid, HDR10, and Dolby Vision. Oh, let's not forget the 10-bit color depth for supporting over 1B colors.

The official brightness numbers are as follows - 800nits typical, 1,600nits maximum, and 2,500nits of peak brightness. This means the Find X8 Ultra has lower peak brightness compared to the Find X8 Pro and Find X7 Ultra (4,500 nits).

In our display measurements, the numbers are alright - the maximum manual brightness was 791nits, while the maximum automatic turned out to be 1,157nits. The minimum brightness at a white patch was 2 nits.

For some reason, we couldn't get it to fire anywhere near the promised 1,600nits.

The Find X8 Ultra LTPO OLED screen supports dynamic refresh rate switching between various modes in the 1Hz to 120Hz range.

There are three refresh rate options - Auto, High, and Standard. All of these modes offer dynamic switching and will go down to 1Hz for static images, 30Hz for streaming, and 60Hz for gaming. The Auto often uses 90Hz for UI inside many apps, while High will max out at 120Hz, obviously.

The refresh rate is also dependent on the combination of content, user interaction, and brightness. For example, if you're in auto brightness mode, a dim environment will result in lower brightness and, thus, potentially higher refresh rate. But in normal brightness conditions, we observed the usual dialing down to 1Hz for idle states.

Oppo Find X8 Ultra supports HDR Vivid, HDR10 and Dolby Vision, though Netflix does not recognize its HDR capabilities just yet.

There is also support for the Android Ultra HDR standard - it allows displaying HDR photos with enhanced tone mapping and a brightness boost for highlights. It's implemented in the in-house Photos gallery, where you get a button to turn it off on a photo-by-photo basis for comparison, in addition to being able to switch it off globally in settings. It also works in Google Photos.

Battery life

The Oppo Find X8 Ultra is powered by a 6,100mAh Si/C battery, an update over the 5,000mAh battery inside the Find X7 Ultra. It's a two-cell battery capable of up to 100W wired charging.

The Oppo Find X8 Ultra posted an Active Use Score of 14 hours and 31 minutes, which is pretty great in isolation. It did very well on our call, web and video tests, and its gaming time is quite alright, too. But the Find X8 Ultra numbers are rather impressive when compared to the competition from the same premium bracket.

Charging speed

The Find X8 Ultra supports up to 100W SuperVOOC wired charging, up to 50W wireless charging provided you have a proper magnetic charger and magnetic case, and up to 10W reverse wireless charging.

The phone arrives with a 100W charger inside the box, as well as a 10A-rated cable, so we've completed our charging test with the said duo.

The Find X8 Ultra has this Smart Rapid Charging option, which you must use to allow for the fastest possible recharging. Otherwise, the phone will charge somewhat more slowly to balance fast charging, internal temperature, and healthier completion in the upper percentage range.

We tested with this option turned ON, but if you want to keep your battery lifespan as long as possible, you may want to turn it off and add about 10-15 minutes to your full cycles.

The phone's battery charged from 0 to 25% in just 5 minutes and reached 58% at the 15-minute checkpoint. Half an hour on the 100W charger gave us 94%, and we saw the Find X8 Ultra hit 100% charge at the 37-minute mark.

Speakers

The Find X8 Ultra features a dual speaker setup. The top speaker outputs through two openings - a top-facing one and another, front-facing one for earpiece purposes. Then there is the bottom speaker with three oval outlets.

The audio playback is handled in a familiar way - in portrait orientation, the top speaker gets the left channel, while in landscape the phone will switch channels to match the correct orientation. No matter the orientation, each speaker will still play some of the opposite channel's track but at a lower volume.

The Find X8 Ultra scored a Good mark on our loudness test. The audio quality is very good - there is enough bass, good vocals and well-presented high frequency range.

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.
