Does having 4G on use more battery?

Does having 4G on, even just for background updates and the like, use more battery?

For Data use in terms of efficiency: 4G > 3G > 2G
For calling in terms of efficiency: 2G > 3G > 4G
If 4G calling is supported and not emulated: 4G > 2G > 3G Note: I don’t think any EU network supports this yet

Most of the battery drain comes for phone looking for a signal. If you are in the area with bad 4G coverage you will have high battery drain as phone keeps looking for a signal. Better to disable 4G and use 3G.
Above applies to areas with bad 3G coverage also. If there is no consistent 3G coverage 2G will be more efficient on battery in idle.

The rest comes down to phone specifics. 2G, 3G and 4G are three separate radios that can all be connected at the same time draining three times your battery. You can make a call using 2G, while synching data on 3G or 4G.
Usually, if phone is connected to 2G it will look for 3G and 4G draining battery. Same applies to 3G connection – phone will look for 4G also. Depending on the phone two connections can be maintained at the same – 4G and 3G or 3G and 2G.
Some phones allow you to manually select which network you want to be using. In settings you are able to select 2G only, 3G only, 4G only, 2G + 3G, 3G + 4G combinations. You will get best battery when you select connection mode manually based on connectivity available in your area.
