That’s hilarious. No major facilities-based mobile network provider in the US has used physical 2G hardware for many years.
Everything was converted to software-defined remote radio heads long ago. The RRHs get mounted up in the air directly behind the antenna element arrays. The same RRHs that power LTE RANs can do GSM just fine.
GSM is computationally and spectrally an afterthought. They literally shove it into the guard bands at the far edges of the PCS LTE carrier.

How is battery life measured under this new EU regulation?
One interesting detail is that the battery endurance rating in the new labels is tested using the same software used by many tech reviewers: SmartViser. This French automation company works with labs and manufacturers to simulate real-world usage. So now, the battery performance you see on the label is based on consistent, lab-tested data, not just marketing claims.
