I know the speed difference can be huge, but how does this affect battery life? I can imagine that it takes longer on GPRS to surf the web, download apps and -thus?- requiring more battery power in the long run than a shorter amount of time (less battery) on 3G/4G.
And is there a difference in standby mode?
As well as the bullets/percentage network coverage? Is more better for your battery life?

In usage LTE uses more power. LTE because it's not as optimized yet will suck use more power in the short bursts and as a result cause the CPUs to spike as well too to process all that data right away. Also because of the bandwidth requirements for LTE (5Mhz chunks vs 200Khz chunks for 3G) it requires more power as well to monitor that.
During idle, 3G uses more since LTE now is a DATA only application. They are working on VoLTE (Voice over LTE) but it murders battery life. Dropping back to 2G for voice uses less power.
Obviously the more solid network coverage is the better your signal will be which means your phone doesn't have to power up the amplifiers all the way to send a signal back to the tower. So if we built all brand new LTE/UMTS/GSM networks today with GSM being less propogated, it would be the worse regarding battery life. We have the opposite today because GSM is the oldest so it's been built out to cover everything and everywhere (even though they are slowly stripping it away to shut it down by 2017).
This is why we still have the same or less battery life in all these years. All the tech improves but just battery doesn't improve enough to compensate for the higher demands to give us MORE than we had before. We basically end up with the same amount of battery life even if we do much more now on our devices vs 5yrs ago. Go to the full post
