I can tell you this... I have a Z10 - not a good battery when it was new, but the last few months I was still using it, I got maybe 6 hours on a charge. Even if I wasn't actively using it.

Once I switched to another phone, and my SIM was deactivated, I turned the cellular radio off, and had only wi-fi on.

Still keeping an active email account syncing, and leaving the phone on, it fairly quickly extended its charge to 3 days.

Now, if I start actively using it, like taking pictures and playing with Story Maker, it will die in about an hour. It will last a bit longer if I'm just browsing or reading the CB10 app.

But it's obvious to me that the cellular radio is a much bigger drain on the battery than just wi-fi usage.

I ran a classic full time for around one year and used a mixture of both - sometimes WiFi only and at other times, both.

I was in good coverage for both. In my experience mobile data used significantly more battery than WiFi only. I would estimate twice the drain.

With those older modems... 100% LTE uses the most. Lot's of folks experimented and saw big savings by shutting off LTE. Even after LTE was more common.

When downloading big files, slower networks will be keep running connections for longer and use more battery. For occasional pings, lower energy radio (2G even) can extend battery life. As a rule of thumb, Wi-Fi provides the best speed to battery life tradeoff. 4G LTE is best when downloading big stuff, 3G/2G is best for checking for new emails.

On my android phone, 4g uses less battery than 3g. On my classic, it is reversed. 3g usess less battely than 4g. Probably because 4g is a bit less covered so it often switches to 3g.
