Gnex Wifi N 5Ghz vs 2.4 Ghz battery drain ... - Samsung Galaxy Nexus

Has anyone noticed more battery drain with your Gnex connected to 5Ghz Wifi N vs 2.4Ghz or is it just me?
thanks

No? Anyone? ...

5GHz is broken for most—so it’s unsurprising you haven’t gotten any responses.

5ghz is NOT broken for most. For some, sure. It is limited though.
I am connected daily to 5ghz. No drops, no excessive drain.
@the OP: I have no had worse battery life, but I do have weaker signal (which is to be expected). What channel are you using?

My 5Ghz connection to my Gnex is great but I do have the quite expensive Cisco E4200 router ...

I believe that it was the GLaDOS kernel that I was using which was the problem. Once I left the "stock" CyanogenMod 9 kernel I haven't had any more problems with battery drain. I'm not really sure if it was really GLaDOS on 5Ghz that was causing the excessive battery drain or not? While I was using 2.4Ghz i didn't have nearly the excessive battery drain that I did while on 5Ghz but i didn't properly troubleshoot while on GLaDOS either because I've been quite content with the "stock" CM9 kernel and getting better battery life.
Yes 5Ghz signal and range are less than the 2.4Ghz signal and range like you said that's to be expected ... I'm not sure the channel its set to auto i suppose i could switch to another channel but i won't because i'm quite content with my connection again
Thanks for the responses guys

Painfully Slow Wifi

So I just realized what I had always suspected: my wifi is terribly slow. I've had my inc for 7 months and I rarely turn wifi on at home because its simply not worth the 10 seconds or so it takes to get started. I just did a speed test on my inc and got .85 mbps. My computer gets 27 with Comcasts speed boost but usually around the 15 mbps that I should be getting. I have a laptop in the other room that gets 17, and my ipod touch gets about 10. But no matter what I do, I get less thatn 1 mbps on my inc. The upload speed is about 2.5, where its about 3.5 on the Ipod, but that's not the issue. Does anyone know of anything I can do with my router settings or inc settings or do I maybe just have a bad wifi chip?
I'm currently running OMFGB btw.
yeah, my wifi is pretty damn slow on mine too. sometimes it'll say its getting 5-6mbps with speedtest, while my computer gets 15-20.

Try checking what channel your wifi is using. If you are in a highly populated area (ex. an apartment complex), your router may be on the same channel as several others which can dramatically slow down your performance. You might have a wireless b/g/n router and your laptop can see the n frequency (5G) while our Inc's can only see the b/g frequency (2G), and in that case, that is why your computer is getting better performance. Most newer computers (and some older) can see this 5G frequency, while most mobile devices can only see the 2G, which is why you're phone's speed is slowing down. Try a different channel that is empty or less crowded. It is quite common for many routers to operate on the same channel and newer routers have a function that automatically will switch to the least populated channel. Hope this helps, it has helped me in the past.

Thanks for the response I think this is my problem! I don't live in an apartment complex so I don't think that is the issue but I do think it is my router as I was just at my girlfriend's and was able to get the 5 mbps hers puts out. Any idea how I may go about changing the b/g/n to just b/g? I don't see an option in the router settings. I have a linksys. I now know I'm sort of in the wrong place but any help would be appreciated!
Edit: Never mind got it! Thanks!

[Q] 4G or WiFi drains more battery?

what wastes more energy? having 4g on or having wifi on? i read the other threads but it had to do with 3g.. they said 3g wastes more power. is this the case with 4g as well?
thanks!
WiFi drains more battery always
that's from personal observation on all the phones i've owned in the past to now
as soon as you use WiFi the battery drains like there's no tomorrow
however this phone seems to handle it quite well
Yeah, 4G is a big battery hog. Wifi doesn't drain as much so long as you are connected to the same one for a while.
EDIT: just saw AllGamer's reply. Wifi really drains that much? I remember seeing the Droid Razr review saying that 4G eats batteries for breakfast. I might be wrong then!

They both drain battery about the same in my opinion.
When ever I can I turn both of them off to save battery.
It's really easy with the toggles that a couple roms have.
This phone is a BEAST!
From my personal experience wifi doesn't drain as much as 4g.

WiFi is far more efficient than the cellular network, and any usage will count against your allocated full speed GB's.. not a good thing.
don't have a sgsII yet but my experience with my vibrant is that wifi if connected uses less battery than hspa. If I'm not connected to a wifi network it drains the battery looking for one.

lol so there's no unanimous answer. i guess i'll just try to experiment a little and see which one uses more. thanks everyone.
4G uses more battery than WiFi
Definitely 4G... I sit on wifi all day and do not use much battery at all.

For sure. And after that I'd say HSPA+ > WiFi in terms of battery draining.

ok guys lets keep this topic sane, yeah it's funny, but lets go back on topic
it's a very valid & informative question
my personal experience shows me WiFi is worst, but others here says 3G/4G is even worse, but from personal experience 3G/4G is less than WiFi
so even i find that contradiction very interesting
the thing that could make a difference is the signal strength, perhaps better 3G/4G reception requires less power to maintain the connection?
possibly the same reason why WiFi always seems to do worse for me, because all the Starbucks, Airport, Hotel, Library, and other coffe/restaurant places that offer WiFi it's horrible, very slow, and hard to maintain signal, probably because tooooooooo many people are hogging it or maybe just because too many devices are bumping each other off the Router/WiFi AP on those establishments
Whenever I use wifi I turn my data off and gst better battery that way. If you have a bad data signal or wifi it'll take more battery to try to keep a connection.
In my Bio class I have terrible data signal and my battery will drain really fast with heavy use but if I turn on my wifi and turn off the data my battery iis way better
Sent from my SGH-T989 using XDA App
So after doing testing of my own I have come to the conclusion that 4G drains more battery than wifi. With wifi I can get about 14 hrs, but with 4G I only get 6-8 hrs.
This phone is a BEAST!
AllGamer, makes sense. If you have slower networks, your screen will be on for longer as you wait inbetween pages and downloads. Fast downloads => less screen time.
My personal experience with wifi vs THREE-g is that wifi eats my battery quickly (on all previous phones and there have been many, including present BB Torch for work). An d 3G doesn't drain as quickly.
However I agree wifi seems pretty sippy and efficient on the SGH-T989. My battery is learning. I am now getting 1 day and 13 hours of discharge time. Very moderate use. 4G. So yes there well may be a difference between 3 and 4G.
I will test wifi-only as soon as I can in the next few days.

[Q] Weak Wi-Fi

So I just got my Nexus 7 fhd couple days ago. I've noticed that it has very weak wifi reception. When I in the same room as router I have full signal, behind one door half signal, and behind a second 0 signal, on my laptop and iphone i get about 70% signal behind a 2nd door (it's probably only 15 feet away from the router). I'm running on Wireless N 300mbit 5GHz if it matters. I read similar thread for old N7 but didn't find any solution, wonder if anyone else have the same problem? Android 4.4.2. Thank you
Is there interference with other routers on the same channel?
Also noticed a teensy bit weaker wifi reception compared to 2012 nexus 7.

It's not a little bit, i'm 10 feet away from a router and have only half bars while all my other devices show full signal
Also i tried different ROMs
I have the opposite experience in that I get better reception with my N7 than any of my other devices. When I have had issues with Wi-Fi reception with other devices in the past, the only thing I found that would fix it was to reboot and reset the router. And oddly enough, once or twice the only thing that worked was to change the password. Hope you find a solution because this thing rips when you have a good signal.

WiFi ridiculous slow now

Suddenly in the last 4 days or so my WiFi on the 5X is incredibly slow. Say if you're downloading an update on the play store or loading a Web page, it will just sit there and try to load. If you give it long enough it will eventually load. It doesn't do this all of the time but seems to be getting worse. I can cut WiFi off and it loads great on lte. My Nexus 6 does fine on WiFi. Anyone else having this problem?
Same here sometimes it works fine and other times it hangs up nexus 5 works fine

Reboot router or try forcing 2.4Ghz or 5Ghz in the device's settings.

WiFi issues are common with any device, you could find similar threads in every device forum on XDA. Each home network is different with unique routers, different settings, etc. Basic WiFi troubleshooting steps are the best place to start.
Knowing your WiFi is working is a good start but there's probably a setting or incompatibility somewhere causing the slow downs.
Just an FYI for anyone else that might have this problem. I tried everything and no luck. Google is sending me a replacement.
Hi,
I just recently ditched my galaxy s3 bcoz of the lag, seems like it's better than my new nexus 5x in terms of wifi.
An app from the play store downloaded faster on my s3 than it did on my N 5x.
Out of the box, my 5X was painfully slow on WiFi. Called Google. Tried the usual cast of 'fixes' with no improvement. Google is sending a replacement, but based on my experience with the Nexus 4 (they still haven't fixed the 4's WiFi issues) I am not hopeful. My Nexus 5 works extremely well, so may just keep it for another year or two.

I'm kinda feeling the same way.
Tried forcing the device to 2.4ghz or 5ghz in its WiFi settings?
In the WiFi's advanced menu you can force either 2.4 or 5 ghz. Just tested on mine. 5 ghz got the expected ~20 ms ping with 60 mb download speed. And 2.4 ghz got 600 ms ping with 0.1 mb download. Might be interference here at work because there are 15 Bluetooth devices here. Will have to confirm when I get home.
I tried forcing the various ghz, just made wifi not work at all. My download speeds seem fine but I'm getting virtually no upload speeds. Had a 6P I was trying out and it worked fine.

Got the replacement 5X today. WiFi speeds are slightly better, but still grossly unacceptable, as compared to the Nexus 5. Got another RMA and decided there's no 5X in my future. Sticking with the 5.

One of them (2.4Ghz or 5Ghz) may not work if the WiFi network doesn't support that frequency. For instance my aging Wireless G network only supports 2.4Ghz and if I set it to auto I may experience strange WiFi issues, if I set it to 5Ghz it won't work at all.
One of them has to work though or you'd never get any WiFi signal.

That's too bad, WiFi on this phone is twice as fast as the N5. Dual MIMO antennas and double the maximum theoretical bandwidth compared to the N5.

Perhaps I should try another router before giving up on the 5X. I haven't had any issues with the Linksys E4200v2 but one never knows. I'll enable WiFi on the brand-new cable modem and see if it's any better.
Just reviving this thread to see if anyone reached resolution.
I'm seeing consistent 4-6 Mbps downloads on an older 2.5 mixed router. On uploads I see in the 15 Mbps range. Every now and then I'll see downloads in the 20-30 Mbps range.
My laptop on the same router at the same time consistently maxes out at 30 Mbps downloads.
I had identical problems with two 5X's, intermittent & slow wifi, on 2.4G (I don't have a 5G router yet.) My previous Nexus 4's and all other devices worked fine.
BUT, when I upgraded my wireless AP's firmware (it was fairly old) and changed from 40Mhz to 20Mhz band (there is a lot of 2.4G interference in my area) the problems went away completely and it's been solid. I've heard similar stories in other threads about 5X wifi being fixed by router updates.
So try changing to 20Mhz band if you're on 40 now (on 2.4Ghz). Also upgrade your router firmware if it's older.
I'm not making excuses for the phone not working well in this scenario, just saying it made a tremendous difference for me. I wish I had any idea what 'fix' might have been in the firmware updates, but it was like 2+ years worth I skipped over, and it's not documented well. My AP is a Ubiquiti UAP, if anyone has similar.
So I would say to anyone having issues, it's very unlikely your actual phone is bad, but there may be some incompatibility especially with older wifi routers/AP.
Thanks. Tried setting the channel width to 20 mhz w/ no impact. Tried shifting the channel to a less used on and still seeing the same ~4 Mbps download and 11 Mbps upload. I don't get why the download is less than the upload. I had similar issues with a newer router so not sure that's it either...
I saw the exact same, where upload was erratic but generally much faster than download. Unfortunately it's probably not 'new' vs 'old' routers, just some certain feature/algorithm/behavior. Even though it works now for me at home, I have no doubt I'll run into lots of places where I'm on some other wifi and it will degrade horribly again. So although it may be 'solvable', I still consider this a pretty significant issue with the 5X, since most places you have no control over the router.
.... and after about 2 days of good behavior, my 5X is stuck at ~2.75 down, 22 up. So flashing the router only worked temporarily.
It definitely looks like something with backward compatibility with older routers. Nice new 5 ghz router at work and hitting 55 Mbps download speeds. Similar uploads as with my home router. Waiting on a new wireless mesh system for home, so guess I have to deal with it until they ship in Feb.....

5ghz wifi issue

I've been running resurrection rom for the last month and change. Flawless performance except the wifi issue. It'd the only rom I've used that has it. I'm forced to use my 2.4 wifi signal. My 5ghz shows up but it's stupid slow and has less signal strength? Even though it's coming from the same router. I've changed channels. Idk what to do. This is the only rom it happens on. As you can see in the picture it's weaker yet coming from the same router.
5ghz by nature of it being a higher energy wavelength doesn't penetrate through walls nearly as well as 2.4ghz so to have a lower signal strength with an equal amplifier power is to be expected. Diagnosing a slower speed is basically impossible to do based on the info you provided though.

Sorry should have also posted a speed test. I'm getting my full speeds. Actually a bit better. I'm getting from 25-30 mbps. Same with 5 and 2.4...its just when I actually go to use the internet for anything it's slow on the 5. YouTube videos barely play in 480.and the router is in a room 15 feet from me. It's no slouch either it's an ac1600. I know it's something with the rom just not sure what.

Disable it from the router or phone? I'm familiar with ipv6 but not with Android. I'm guessing it's rom based because of the drivers because 5ghz worked flawless on OSS before I rooted

yea android's default behavior with ipv6 is bad most manufacturers make tweaks with their official software to fix it but some roms don't incorporate those changes because they may or may not be open source.
