i stumbled upon some actual research on power consumption in 4G VOLTE and 5G VONR
source : https://www.researchgate.net/public...tion_in_4G_VoLTE_and_5G_VoNR_Over_IMS_Network
In very plain language: this paper says 5G voice calling (VoNR) uses less battery and usually sounds cleaner than 4G voice calling (VoLTE) when both are run over IMS, which is the voice-call system used by modern networks. They tested this with a high-end 5G phone, a network test setup, and a power meter.
What they did was basically this: they made the phone sit idle, attach to the network, and then do a 60-second voice call. They compared 4G bands (B7, B28) with 5G bands (N7, N28), and they measured both battery drain and jitter. Jitter is just how “messy” or unstable the voice packets are; lower jitter means smoother call quality.
The results are the main point:
So the simple conclusion is: if your phone stays on 5G for voice calling and VoNR is available, the paper says you should get better call quality and better battery life than on 4G VoLTE. They also say the lower battery use happens because 5G’s core network separates control and data traffic more efficiently than 4G’s setup.
One tiny correction: the paper’s numbers are from a lab test on one phone and one setup, so it is not a guarantee for every phone or every network. It is still a pretty strong sign that VoNR is the better setup when your network supports it.

The results are the main point:
- 5G used less power than 4G in every case they tested.
- In idle mode, N7 saved 17.78% energy vs B7, and N28 saved 38.88% vs B28.
- During the call itself, N7 saved 12.63% vs B7, and N28 saved 35.87% vs B28.
- For call quality, VoNR had much lower jitter than VoLTE. At 2600 MHz, VoNR averaged about 0.09 ms jitter vs 13.77 ms for VoLTE. At 700 MHz, VoNR was again about 0.09 ms vs 16.59 ms for VoLTE.
So the simple conclusion is: if your phone stays on 5G for voice calling and VoNR is available, the paper says you should get better call quality and better battery life than on 4G VoLTE.
