Can we use only 3g internet not video call service so that we can save battery ???

3G has a higher battery drain, however, it actually uses less Watts per downloaded Kilobyte compared to 2G. 3G is much better for heavy data usage, and will not use much more battery if the 3G signal is strong. If the signal is poor or fluctuating, however, it may drain your battery as much as twice as fast compared to 2G. Talk time is considerably less than 2G, however, standby drain is about the same. Overall, under typical conditions in suburban areas, you should expect about 2/3 of the 2G battery life.

Hi I tried looking for a similar thread but couldn't find one. So I was curious if my g2x battery use is normal. When I look it up my battery use is mostly consumed by cell stand by. I'm not running 4g I'm using 2g. Is this normal?

It is normal. If you click on it and your time without a signal is high then you may have a poor signal or another issue. Searching for signal will kill the battery pretty quick.
I clicked on it and I don't get any indication of time without signal. All it says its time on 2h 43m 50s. Could it be the battery it self? I've left the phone mostly idling this whole time and its already down to 86% . I've tried all the tips like only use 2g, lowest display, and juice defender. In like 6 hours I'm down to like almost 55 percent.
Normal idle drain for me is between 2% and 4% an hour. In areas with weak reception such as my office, the drain can be much higher due to the radio switching between 2g and 4g looking for a strong signal. I have gotten into the habbit of switching to 2g only at the office. You might try it for a day as a test to see if it helps. I know it is not a great solution, but it is what it is.
Any expert can tell me why 3G Data Connection consumes more battery than Wifi?
I have done experiment on turning on just:
1. Wifi
2. 3G Data connection
All other functions/apps stay the same.
1. lasted over 20 hours with minimal usage
2. lasted no more than 13 hours with minimal usage.
Any expert has an explanation?
I'm not an expert, but I've observed the same thing that you have, 3G uses more power than WiFi, both at idle and "in use" (such as streaming music).
On my HTC Hero, using WiFi, 1%/hour idle, approx 2.5-3%/hr "in use". With 3G, approx 4%/hour idle, 10-15%/hour "in use".
It takes more power to boost up your transmit signal from your phone to reach the cell tower 2 miles away compared to the wifi hotspot 5 meters away?

thanks
yeah, because i was thinking when using wifi, there is an extra device running.
but when on 3G data, shouldn't it be the same thing as the normal phone signal?
so why would 3G data consume more battery than wifi? thats what is puzzling me.

3G (UMTS) and 2G (GSM) are usually implemented as two different subsytems. 3 years ago, when I was working with their designs, devices actually had 2 antennas internally, because of optimsation for different frequencies.

i am no technical person but I am guessing .. that means when I turn on 3G data, I am using something that is NOT related to the original phone signal connection and that is why it consumes battery on top of the original phone signal connection?
and so happens the UMTS consumes more battery than Wifi too?
Wifi just sucks more battery in general

but in fact, the phone operates under wifi is more battery saving than operating under 3G connection...
Hello,
there are many threads and posts related to battery drain on our smartphones.
But is it a rule that wifi takes always more battery drain than 3G ?
Does the over air communication physically need more energy for Wifi than 3G GSM ? Or is it just a driver issue ?
actually wifi takes less power than 3g didn't really look up why but it is more energy efficient. If wifi is available I would defiantly use it over 3g because its greeter for the battery and faster.
Hey guys just wanted to know how does different network/radio affect the battery life? I am on rogers.. if I am on LTE I usually only get about 10hour or less on 3G I can go for more then 2 days...
There is no easy answer to this question. Battery life is often a function of network reception, which varies drastically by location. If you are seeing such a huge difference from being on LTE, its possible you are in a fringe LTE reception zone and the phone is constantly scanning and trying to connect to LTE and draining the battery. Flashing a different radio may help, but its not necessarily a silver bullet.
Battery life always varies quite a bit from person to person, even regardless of LTE. LTE adds another level of complication. I'm on LTE all day, and I can easily get 24 hours or more before needing to charge. I think some on here have mentioned getting 2 days on LTE.
I'm on LTE 24/7 and my phone makes it through days no prob. I do charge each night while sleeping, but that's to be expected IMo.
Using: HTC One X // Paranoid Android // Tapatalk
Generally speaking, my battery life is pretty good. However, at least half the day, I am in areas of poor cellular strength; I am usually in the -120 to -100 dBm range. I know this is eating up my battery, but is there anything I can do about it? I don't really want to manually go in and out of airplane mode, but I guess I will if I have to. I do turn off mobile data and stick to WiFi, but the phone radio is still sucking the battery juice.
Does anyone have any advice on how to save some battery in poor coverage areas?
When I am at parents I have no service (which destroys battery like you said) so I use Google voice and VoIP over WiFi. It greatly helps but a bit of a pain setting up. I know not perfect answer but it's all the help I have to offer
The radio on this device does not eat that much battery... on average my device spends most of the time over -100db signal and gets great battery life.
