Wireless N & Battery Life

[ellisz]

hmmm. I am having a similar issue but I think it is my phone. I recently upgraded to a Netgear N600 dual band and the SF is connecting to the 2.4ghz band and I use the same encryption method as you. I also have a Linksys WRT54g linked to the netgear via a firmware upgrade. I have not updated the netgear firmware as I read it was worse.

My battery has sucked since getting EB01. I noticed last night that my wifi was "running" 100% of the time. It is not going off. When I am out and there is no wireless, the phone gets warm and drains the battery fast. I currently have my wireless to go to sleep when the phone is off but I still had a pretty fast drain today. I was at 25% before by 1pm and I had no voice calls, no texts and maybe a few e-mails. No other activity except for about 10 minutes of web surfing. I pulled the phone off the charger at 7 am today too!

I would hate to think it was the router. Not sure how that is really possible...

you would be amazed at the stupid crap routers can cause. have you tried reflashing a kernel?

I am running stock EB01 I have been home all day and have had WiFi turned on all day. Almost 90% battery. Go to your settings<about phone<battery use and see what it is showing

Might I add also, prior to this I've *never* had battery issues on my Fascinate. I've always been able to get a solid 18 or so hours out of it before getting down to 10% or less life remaining.

I am not aware of a kernel to flash. I have flashed the SC 2.4 multiple times. I removed my theme, reset bat stats, wipe cache, wipe dalvik, etc. I have not tried the permissions fix. I had the issue on voodoo and non-voodoo. I am currently nv. I wish we would get the kernel source so I could play with some modded kernels.

spare parts actually has wifi running at .1%. Seems to be working since I last charged - few hours ago. According to about phone, 76% is my display. I have auto brightness off and I have it turned down to the 1/4 mark.

Okay, update on this. Spent all night screwing around with things and monitoring battery life, seems to be nothing has any real positive effect on performance unless I turn off N. The moment I either turn off N or switch back to a G only router, bam, it's like magic.

Unfortunately that completely defeats the purpose of it. =\

just so we are clear, you are turning the n off at the router, correct.

Yeah that kind of goes with some of the research I did last night. Unfortunately I couldn't find anything Android specific I did find one about Pre that showed a lot of people having problems with Netgear and DLink (seemed somewhat model specific) routers having a lot of drain on battery life. If you know anyone with a Linksys N you might try that and see if it works.

BTW what's the set up on your phone. Could also look into kernel conflict.

So having N turned on is draining the battery on the phone even though it can't connect to that band? This makes no sense.

I will try it this weekend myself.

The phone can connect to an N router. It cannot utilize the 5ghz bandwidth which gives the N the maximum speeds. It only connects to the 2.4ghz bandwidth.

The router I have has dual bands and I have 2 separate SSID's. The only things that see the 5ghz band is the devices with N cards in them. The rest, including the SF see the 2.4 ghz band. I mistakenly thought that N was 5ghz and G was 2.4ghz. I was mistaken ... oops.

So we are saying that forcing the router into a G mode only is helping with the battery life on the phone? I can turn the 5ghz radio off but that appears to be it. I don't see the option to select what mode to look for. I know my old Linksys with Tomato on it had that option.

So i'll throw in my pennies here. I'm hearing the samsung is N capable, but not N compatible? If that's the problem, then it makes good sense that the phone is constantly pumping away at that N connection, but can't get hooked up. Instead of making the connection, then just moving data it's sending the handshake non-stop all the time without being able to get positive contact. If that's the case then the only fix is to kill the N connection. I'll also throw in that unless you're bruce wayne an N router is pointless for internet use, since your modem probably can't even get 2% of that connection potential. Sorry if this isn't helpful but I wanna play geek too.

Set up on the phone is DL30, with the DL09 radio. Was actually at a friends house earlier, he had a Linksys N Router, and I was noticing the same amount of drain on his router as well, so I don't think it's just router related (in terms of brand or set-up).

@Sheepdog...I've heard this to an extent as well, but it should be able to connect and maintain a solid connection just fine at the 2.4 Ghz band. I event went as far as blocking the 5 Ghz frequency, which again seemed to have zero effect.

I know this thread is a bit old here, but were you ever able to resolve the issue?

I notice the same problem with my phone (an HTC Inspire 4G) that when I'm connected to my "G" hub the battery will last a couple days, but when I'm on my newer "N" router it only lasts half a day. I resorted to just leaving my "G" router on and active, acting as a sub-hub and connecting to my "N" router as if it was the internet connection. That worked great for awhile, but now I want to use a Google ChromeCast and the ChromeCast doesn't work across a router (tried DMZ, uPNP, etc. but that's off topic for this thread).

Any help is appreciated!
