From a battery perspective, should I use wifi? Most of the time i'm at home or at work where I have wifi. I also have good lte coverage at both. Speed aside, will I save battery by not using wifi or not?
You'll definitely save battery by using wifi when you can connect. I love the speeds over lte, but it is definitely a hog...
i also had boost of battery using WIFI
Using unlimited data plan makes me to consider using 4g, but I found that Wifi consumes much less battery.
Use wifi. The battery savings are huge.
yes i cant stress enough, wifi saves enormous amounts of battery so use it when ever possible. the difference is like night and day.
Compared to 3G
I've been leaving my wifi off since I have unlimited data and the 3G is pretty fast in my area, no 4G yet.
I've had pretty good battery life lately using only 3G, I'll have to do a few tests and see which one and I'm a fairly heavy user I'm approaching 4GB this month and none of that is tethering
3G or Wifi
Tested watching a streaming video of 22 mins
on 3G I lost 13%
on wifi I lost 8%
Wifi wins, of course standby is probably different, if 3G vs wifi loses this badly I'd have to imagine LTE vs Wifi is a slaughter battery wise
Actually I found something interesting...
For some reason, even when I am home using Wifi, the battery drains faster than I thought. Where I live is like a strange signal spot. If I turn off my WiFi I can see my TBolt constantly switching between LTE and 3G, sometimes it stucks on 1xRTT for a while then goes right back to switching between connections. If I am at work (downtown LA) where the LTE is pretty well covered, I still use WiFi at the office, the battery BARELY drain at ALL.
My theory is that even when WiFi is active, the phone somehow STILL does the LTE/EvDO switching on the background does draining the battery.
If somehow the devs or VZW can tell the phone to STICK to EvDO/1xRTT instead of going back and forth with the LTE while WiFi data is on, it'll solve the problem.
Also just FYI, I have the latest radio and BMAF 1.5 remixed.

pretty much correct. at least on the gsm side, when i connect to wifi at home, i can no longer see if the phone is on 3G or EDGE. but it definitely switches back and forth to those networks, while staying on wifi, you just dont see the icon switching, but its definitely happening. i dont see why cdma and 1x would be any different.
if this is the case then why don't you just turn data off when you are on wifi.

You are absolutly right! How come I never thought of that. Will do that when I get home tonight.
Thanks for the tip!

Better yet get juice defender and automate it . Its very good app. Right now it says I'm almost adding fifty percent on to my battery.
I seem to be bucking the trend here, but LTE is working better for me than wifi. I usually have a good signal, so that's part of it.
The other part is that my wifi may be eating more juice than normal because the TB and my router may not be playing nice together. Ever since I added the TB to the network, I've had to reboot the router every coupla days. Before the TB, it was solid weeks on end.
Has anyone who is still having trouble on with batter on wifi set their wifi sleep policy to "Never" sleep? Mine is set to this and if I am home most of the day I will lose very little battery through out the day.
I believe by default the wifi is set to turn off after a period of time or when the screen is off so during this time I believe you are actually reverting back to using the vzw network. To turn wifi to always on go to settings>wireless>wifi settings>hit menu>advanced. The sleep policy is at the top, change sleep policy to never. This my reduce battery while not connected to wifi so I always use the power control widget to turn my wifi off completely while I am away from the house.

Oh yeah this is very important, set wifi sleep policy to never greatly increases battery life. Otherwise it switches back to 3g when screen goes off and drains way more battery. This is very important to set this otherwise you wont see the increase.
Is strongly recommend switching to cdma only if yore gonna use WiFi and plan on saving your battery. Otherwise what's the point. I personally don't even bother using WiFi just use LTE only mode. I'm getting better speeds than most WiFi connections using my LTE.

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...
guys
which will drain battery faster -- running on wifi and turning off mobile data (4g) or use 4g mobile network data and keep wifi off?
I've always been told WiFi will prolong battery life rather than 3G/4G. Back when I was at Sprint with the HTC EVO 4G my battery lasted significantly longer on WiFi than it did on 3G. However, Sprint's 4G was a HUGE battery drain. Because T-Mobile and Sprint use different technologies, I'm not sure how accurate my comparison is.
So I'm finding that my LTE coverage is pretty spotty at best in Seattle, in Shoreline (city just north of Seattle) it barely gets a signal and is usually on 4G, but in Lynwood I get a great LTE signal... It's kind of strange that there would be a gap in coverage.
Also, has anyone noticed severe battery drainage since the LTE network went live? My phone's battery has been dying really quickly with phone standby using almost 33%, and phone idle using another 30%.

Hi,
I am trying to get a clear idea on the battery consumption of N5 on Wifi, LTE and E. If the purpose is to be battery friendly, which one (LTE, Wifi, Edge) should I left my phone on most of the time?
Thank you,
Well id say not WiFi! I use Wi-Fi at home and battery life is OK, it actually depends on how much you use it. I'm usually on my tablet at home and on the road my n5. Idk what E is but I'm thinking it's edge so that's probably better than LTE battery wise.

Wi-Fi is by far, the most battery friendly connection because the device only has to transmit and receive from a very short distance. Mobile data signals have to travel to the cell tower so more power is used the farther away you are from it. Less bars, more power used to communicate with the tower. LTE is best because you get that transmission completed very, very fast. HSDPA is good as well. Edge connection is very slow and makes the device hang waiting on the package to be sent and received, thus using more power in the long run. I usually set my phone to edge when I'm not going to be really using it.
Hope that helps.

You certainly want to be using WiFi at home. I tried going data only for a couple days because it's unlimited and the battery drain especially while idle was much higher than using WiFi. This is with full signal 90% of the time.
WiFi is your friend for extended battery life. Mobile data - whether it's LTE, 3G/HSPA+ or good old Edge/2G will vary in power but it's pinging the towers for signal & cycling, so it will use more data - that is, all other things equal in terms of settings including the newer/est KitKat features.
Wifi whenever you can use it.
As far as cellular, as long as you have a decent signal, faster is always better (so the modem can download what it needs and turn back off). So use LTE if you're going to be using any data. Knock it down to edge (or off entirely) if you don't want to use data at all, or just for the occassional notification.
So Wifi is clearly the best. So when my phone is idle for a long time, let say at night, should I leave it under Edge or Wifi?
I am writing a tasker profile, so I just try to see which one is better in term of battery.

Well you can always put it on airplane mode/turn off the mobile radio and switch on Wi-Fi after to just have Wi-Fi data. The catch is, you will not be receiving any calls or SMS/MMS while you have the mobile radio shut off... unless you're using a VOIP service.
