3G Battery Consumption v WIFI

---

Am i right in thinking the main culprit for wasting battery is 3G? when i use WIFI and am at home, the phones goes easy 2 days and im watching youtube, playing angry bird, chatting on gtalk.

with 3G, lucky to get a full day, normally dies towards the end,

so how come 3G kills the battery so hard is there a remedy to it lol

thanks

3g could be trouble when you have weak or unstable signal. In normal cases wifi uses more juice.

for me, 3g doubles the consumption compared to wifi. (t-mobile uk)

Similar issues here on 3 in the UK using official HTC unbranded ROM with radio 32.44.00.32U_5.09.05.30_2. I can get well over a day with as much use as I wanton WiFi but if I switch it off and move to 3G (HSDPA) I completely flatten a battery in anywhere from 3 to 8 hours, sometimes with minimal actual usage!

yh on t-mob too, it could be the signal as iv read weak signals can drain battery, its strange, normally its wifi that drains the battery, but i have it on all day , dont have any inactivity settings on, its full blast all day and the battery stays 70-80% by round 1am when i sleep,

3g, it will be around 20% at that time, it is a strange one

While idle 3G uses more power than WiFi.
While active WiFi uses more power than 3G.

While that may like it seem like WiFi can use more when actively using it. It also finishes quicker and goes back to idling. Which uses less power in the end.

Both use more if the reception/signal is weak, as it's constantly trying to (re)connect.
