Earpiece speaker: part of the shark fin pop-up, audio transparency through the top bezel

Dolby Atmos
Max98927 Class D Amplifier capable of 85dB
Codecs SBC, AAC, aptX/HD, LDAC and other hi-res audio to 32-bit/96kHz.

The top speaker does not match the acoustic properties of the much louder bottom speaker, so any semblance of stereo L/R separation is not really possible.

Maximum ring volume is 82dB (good), and music/voice is 75dB. Hands-free is clear enough in an office environment, and callers did not feel I was in a ‘tunnel’.

Dolby Atmos simply means it can accept 5.1.2 or 7.1.4 Atmos content and downmix it to the 2.0 speakers or headphones/buds. Sorry but the speakers lack the oomph, and there is no sound stage there either. Atmos settings are Smart, Movie, Gaming and Music.

But attach our reference Sony WH-1000XM3 headphones that support SBC, LDAC and aptX/HD, and you get glorious Atmos sound. The premium USB-C buds were not bad either.

Note: Frequency response is from 20Hz to 20kHz

  • Deep Bass: 20-40Hz – none
  • Middle Bass: 40-100Hz – creeping in
  • High Bass: 100 to 200Hz – building
  • Low-mids: 200-400Hz – flat
  • Mids: 400-1000Hz – flat
  • High-mids: 1-2kHz building
  • Low-treble: 2-4kHz – building
  • Treble:4-6kHz – flat
  • High Treble: 6-1kHz – flat
  • Dog whistle: 10-20 – non-existent

This is a bright vocal signature – quite clear and crisp for voice but can be shrill for music and movies. We tried with Dolby Atmos (music preset) on/off.

With Atmos on bass improves and the speakers are ‘listenable’.

With Atmos off the music is shrill and harsh evidenced by no bass, poor mids and excellent treble.

Other Goodix optical fingerprint sensor in-glass
Face recognition
Shark fin The shark fin pop-up is elegant and fast – .08 seconds.
Tested 200,000 uses – 11 years at 50 times a day
Auto retraction if it senses a fall and will not open if there is resistance (in a pocket)

The Goodix optical fingerprint sensor is in-glass. It’s 99.99% accurate and fast – less than a second to unlock the phone.

Face recognition can be a default (why bother) and the sharkfin automatically pops up if Fingerprint Recognition does not work.


Battery 4065 mAh battery (VOOC uses two batteries in parallel for safety)
Charger   Charger type, e.g. 5V/4A (20W)
Quick charge: VOOC 3.0
Wireless Qi charge: NO
Approx recharge time: 50% in 30 minutes and 100% in 60 minutes
GSM Arena endurance rating: 107 hours

The battery is large but comparable for this class of device.

  • 1080p Video loop, 50% brightness, Airplane mode was an astonishing 18 hours
  • General to heavy use patterns – 35 hours
  • Under 100% load, maximum brightness and everything turned on GeekBench 4 estimates around 6% battery use per hour – 16 hours.

These figures are excellent and due to the  AMOLED screen, AI and the power efficiency of the SD855.

Given heavy/typical use, we expect this to run for 24/36+ hours between charges.

In a 4G zone Network Cell Info shows a rock-solid -101dBm 4G signal which is superior to the Samsung Note9 reference phone at -108dBm. What that means is that it gets better 4G reception. It also picked up the next furthest tower at -107dBm where the Samsung Note9 was -141dBm.

In a 4GX Zone using Ookla Speedtest, the OPPO managed 128/40Mbps download/upload versus the Samsung Note9 at 59/30Mbps.
