You may have heard everyone say “WLAN is much better to use than EDGE or 3G to save battery” but rarely you may have experience this difference carefully. Let me tell you my experience.
I have been using Nokia N9 for a month now with WLAN connected for almost whole day. Nokia N9 used to last around 1d 13h easily with average usage, which was surely a better, impressive stats. Recently, I was not having WLAN connectivity and had to use 3G for some usage. Connection was somewhat fluctuating and moving back to EDGE and again 3G (as I was travelling in rural area), which was ultimately consuming more power. In just 2 hours, battery moved from 98% to 50%. Comparing that with WLAN, it was almost 9.25x more consumption, which is just too much.
So, it is always better to use WLAN whenever it is possible. Fluctuating network connection also draw more power from battery than usual. It is possible that 3G connectivity is poor in some area and you are not getting better network strength. In such situation, it is preferable to go to setting and set 2G/GSM from Dual or 3G mode. It will considerably improve your battery life. If you are not using Mobile Data (GPRS/EDGE/3G), turn of Mobile Data to save battery.
Always put widgets to offline modes if you really don’t need them to be updated and want to save battery. Unnecessary background apps also consumes processing power, so it’s better to close them. There are more tips we shared in our previous post. Have a look at it also, if you haven’t already.
