after turning 4g off... massive battery drain, 4g reconnect error - EVO 4G Q&A, Help & Troubleshooting

if I turn on 4g and then turn it of, my 4g constantly tries to reconnect. This results in tremendous battery drain. My alogcat gives me the following error.
E/Wimax ( 103): <DC CONNECT> IO error: msg='/127.0.0.1:7771 - Connection refused'
If I then restart the phone with 4g turned off, the problem does not result until after I again turn on the 4g and then turn it off.
Any help on fixing or preventing this from occurring?

I am seeing this same issue. Are you using any widgets to turn on / off 4g?

it's a known issue if you have a wiget on a home screen to turn on and off 4g. Remove widget from home screen, reboot, and turn on and off 4g from settings is supposed to fix it.

I have no widgets and I get that same message all through logcat. I never turn on my 4G. I don't see any unnecessary power drain tho.

Should you keep 4G on when you are using home wifi?

I noticed that whenever I turn on my wifi at home, the phone automatically disconnects my 4G, even if my 4G widget is turned on. As soon as I turn off my home wifi, the phone will then re-connect to Sprint's wimax network.
Is it ok to leave the 4G widget on while I am at home and have the status of 4G show as disconnected or will doing this drain my battery faster. Right now, I manually turn on 4G and turn off wifi, every time I exit my home and then do the opposite when I return home
Any thoughts?
I say just leave 4G off and use Wifi.

[Q] Keep wifi connected when in standby mode

I bought a used HTC Surround to play with WP7 development. I have no phone service for it and just use wifi. I've found that wifi shuts off when in standby, has anyone found a way to keep it active when in standby? Or even a way to just keep it from auto going into standby? I searched around but didnt see anything.
If you keep it plugged in, wi-fi won't shut off.
The screen timeout can be set to never if you don't set a password, that way the screen won't go to sleep and the wifi will stay active.

Does WIFI kill battery more than T-mo 3G/4G

i checked the option "always" Keep Wi-Fi on during sleep. Does this mean if its "off" that it will use 3g/4g instead? Also does wifi kill battery faster than the networks data
If you have it set to turn off WiFi during sleep, then when you turn off the screen, WiFi turns off and 3G turns on. When you turn the screen back on, 3G turns off and WiFi turns on.
WiFi generally uses less power than constantly being connected to 3G.
Setting WiFi to sleep when the screen is off often hurts battery life with normal use because it takes more power to keep turning radios on and off (over and over again) than it does to just leave them on.

[Q] WiFi Slow to Wake Up

I have a Verizon GN. I have an issue with wifi taking a really long time to wake up after the screen has been off. Turning wifi off and on will usually work quickly, but if I don't do this, I can't access the internet sometimes for over a minute even though the wireless is supposedly on and connected (blue). This happens only on my wireless network at home (not at work). My wireless setting on the phone is set to keep wifi on during sleep and wifi optimization is checked. I've unchecked wifi optimization and it didn't really help. Is there something I need to do to my router?

WiFi doesn't turn off properly

Hi. Today I have discovered what was causing my battery life bad. So, if I turn off WiFi when I'm connected to router - it will turn off properly. When I turn on wifi and turn off (without connecting) it will stay in 'scanning mode' even if the icon says it is turned off. Is there any possible fix for that?
