I have heard that connecting to internet through WLAN improves battery life compared to cellular connection and therefore it it preferable to surf the internet from your phone using wifi. Is this true?

Wifi uses less battery alright,about improving it is another thing.

Thanks for the reply jimmy. I didn't know that wifi consumes less energy

However, i would like to know whether wifi increases battery performance or not. In my opinion, this is not true but i'd like to listen to others' opinion too.

I had a quick google search on this and it seems wifi does use less as its connecting within a distance,3g,edge etc has to connect to a tower,having said that this could be good for some and not good for others,another thing is the data been transmitted too,all in all seems wifi uses less consumption.
i would say it will be an interesting topic with many views to be honest.personally i never use wifi as there is none local so from my view i cant say hence regular charging for me.

From my personal experience, wifi does imporve battery life.

On my N8, I have set my work and home wlan to higher preferences of connectivity, and switch to recognized wlan networks. So when it's in range, it'll connect to the wifi and switch 3g off. That not only saves tons of battery life(seriously, it saved a huge amount of battery life, a measurable amount) and the internet is always on, and is faster. So using wifi is a win in every way

Thanks s3r4ph for sharing your experience with us! It sounds really interesting - I think I'll turn 3G off and I'll try having my C7 connected to my WLAN for a day to see what happens to the battery...
