βœ… Fast connection – the call is set almost instantly.❌ Fast battery drain – on weak processors (e.g. the Snapdragon 665 in the Redmi Note 8) VoLTE can increase power consumption.
βœ… HD-sound – voices sound more natural, without noise.❌ Problems with coverage in some regions 4G-The network is unstable and calls may be cut off.
βœ… Internet while calling – you can talk and use mobile data at the same time.❌ Incompatibility with some carriers – not all SIM cards support VoLTE (for example, virtual carriers like Yota or Tinkoff Mobile).
βœ… The future of communications β€” networks 2G/3G It will be shut down and VoLTE will become the standard.❌ Firmware Glitches - on some versions MIUI VoLTE is unstable (for example, the sound is lost or the icon is not displayed).

In practice, many Redmi Note 8 users are faced with the fact that after activating VoLTE:

  • πŸ”‹ Battery burns 10-15% faster (especially if the network is running) 4G The phone is constantly switching between standards).
  • πŸ“΅ Calls disappear in the subway, elevators or on the outskirts of cities where 4G lingo.
  • πŸ”Š There are noises, sometimes the sound gets worse than the sound. 3G, Due to poor optimization of codecs.

If you live in a big city with good coverage 4G And if you use a SIM card from one of the major operators (MTS, Beeline, MegaFon, Tele2), VoLTE can really improve the quality of communication.
