You can read about Dual Sim setup options on OPPO here. It really offers excellent flexibility.
|Sound||3.5mm audio jack|
Earpiece (mono for phone) plus
becomes stereo with the down-firing speaker
FM Radio (needs wired headphones)
|AMP||Dual Class D TFA98912UK 3.6W RMS at 8 Ohm|
Dolby Atmos decoding
Default res: 16-bit/48kHz
Max res 24-bit/192kHz
This is a loud phone. Ringer is 86dB and voice/music is 76/79dB – outstanding.
I usually criticise the so-called a stereo earpiece and down-firing speaker combo, but it had reasonable separation and similar volume and sound characteristics. Good tuning!
As is OPPO’s style our reference Sony WH-100XM3 headphones sounded superb although we suspect its nothing to do with the SBC codec and more to do with the Dolby Atmos psychoacoustic trickery.
Dolby Atmos means it can accept up to 5.1.2 or 7.1.4 Atmos content and downmix it to the 2.0 speakers or headphones/buds. Atmos settings are Smart, Movie, Gaming and Music.
We tested the 3.5mm buds, and the sound was adequate – no bass, strong mids and weak upper mids and treble.
Deep Bass: 20-40Hz – nil
Middle Bass: 40-100Hz – nil
High Bass: 100 to 200Hz – building
Low-mids: 200-400Hz – still building
Mids: 400-1000Hz – building and flat
High-mids: 1-2kHz – flat
Low-treble: 2-4kHz – flat to peaking
Treble: 4-6kHz – declining
High Treble: 6-10kHz – declining
Dog whistle: 10-20 – dropped off the cliff at 16kHz
This is predominately a bright vocal sound signature that is good for voice but tends to lack the ‘oomph’ for bass.
OPPO has a headphone monitor setting that allows you to hear the smartphone mic via the headphones. Karaoke anyone?
Fingerprint sensor under glass|
Face recognition 2D
This has one of the best under glass scanners I have used. It is fast but not quite as fast as the Reno 5G which is blazing – blame the lower-powered Helio 90 SoC.
Face recognition is also excellent and quick. I tended to use this for convenience over the fingerprint system.
|Charger|| VOOC 3 charger 5V/4A (20W) |
Quick Charge: full in an hour
The battery is large for this class of device. OPPO VOOC is two batteries wired in serial and the Charger is two chargers putting out 5V/2A each. It is an eminently sensible and safer way to give it the capacity and charge speed without overstressing a single 4000mAh battery and USB-PD charger.
The ‘green’ cable USB-A to USB-C is for VOOC to deliver two concurrent charges. If you lose that you can still charge at half rate using the VOOC charger or a 5V/2A charger. It is not USB-C USB-PD compatible but using that charger will not damage it.
Tests: 1080p Video loop, 50% brightness, Airplane mode, 12
Under 100% load and everything turned on it was empty in just over five hours (GeekBench score 5228)
Given typical use we expect this to run for 24+ hours between charges.
