suggestion - 2g in idle for saving battery time

I have an idea to increase, in some situations, the battery time; to receive notifications (for example email or whatsapp, Facebook, Twitter, etc...) is enough even a slow connection like the 2g one, that have the good effect to increase the battery time. So I have thinked that could be a good idea to use the 2g in idle and in all situations when there aren't need to fast connections (I think sms, calls, offline games etc.), when there are that request (for example after tap on a Facebook notification and open the application/browser) the system switch automatically on the 3g/4g network if available. Obviously this must be a selectable option.

What do you think about this?

N900 used to have application that enabled fast change between 2G and 3G. I would rather have it manual so that I can choose when to apply. This of course assumes that there are reasonable powersavings when in 2G. Would like to see some power consumption figures first.

yes, this mode must be activable only on demand, it could be useful in certain situation but not in all cases

Good idea, but it should have an optional setting, if the system should try to switch to 2g-only at all. Unfortunately I don't know much about mobile networks but I was at places in Budapest, Hungary, where there were only 3G coverage with my N9, no 2G. It simply could not log on to any networks.

Interesting... in that situation (only 3g or 4g network) the system should remain on that network... It must be a "preferred 2g switch" not only 2g in idle. so if there will be 2g the system chose it, otherwise it remain on other kind of network

Is there any study that shows this to produce relevant savings?

I'm on a 3G only network with the phones locked to 3G only and I don't really see much difference in battery time. One of the SIMs I have is borderline 2G/3G where I live and was forever switching and caused worse battery usages than my 3G only network. Would this proposal not cause similar power issues switching technologies dependent on the priority of the data?

Wouldn't something like Apple's coalesced updates strategy provide better savings?
