Why do users want to disable VoLTE on Xiaomi?

On paper, VoLTE looks perfect: HD-quality calls, instant connectivity, and the ability to use the Internet while you're talking, but in practice, many people are faced with the reverse side of the coin.

• 🔋 Increased battery consumption. The VoLTE module keeps the connection to the LTE-net that 15-20% Reduces battery life (according to GSMArena tests on Redmi Note) 11 Pro+).
• 📶 Poor coverage: In some regions, operators (such as Tele2 or Iota) are unstable in supporting VoLTE, causing calls to be interrupted or not to reach.
• 📱 Incompatible with firmware. ROM (For example, Pixel Experience or beta versions MIUI VoLTE can work with failures.

Method 1: Disable VoLTE via standard MIUI settings

The easiest way is to use built-in options. MIUI. It is suitable for most modern models (Redmi Note 12, Xiaomi 13, POCO F5 And newer. The instructions are relevant for firmware. MIUI 12.5–14:
