What is "cell standby?" - Galaxy S III Q&A, (US Carriers)

My phone dedicated about 39%to this today, hut I only made one 5 minute call all day.

Standby is energy used simply being connected to tower. This percentage sounds reasonable, depending on usage and signal strength.

Try this method.

Data and Wifi Keeps Shutting Off

So it'll keep shutting off. Mobile Network will shut off and wifi will as well. Whenever I try to turn it back on it says Turning on... and sits there. Then I have to reboot.
I think it might have something to do with my Airave... I dunno.
My wife had the issue. Sprint forced a replacement due to a defective unit.
I'm 100% sure yours is too

Had an issue staying connected to the network. Wasn't ever at proper reception strength.
They could tell. Immediately. I'm sure your the same.

Do you guys have Airaves? I've been talking to a Airave Tech Department and am being told it could be the Airave... and it being my ISP because QoS and "jitter" numbers suck. So I'm on with tech with my ISP. Annoying.

3g icon showing while on WiFi

So this is probably a dumb question but I have nevr had it happen before. My DNA the last couple days intermittently has been showing the 3g icon even while I'm connected to WiFi. I'm not sure but is that a bad thing or not?

If you send or receive a MMS while on WiFi your data will come on for a second or 2

Thank you. I honestly wasn't aware of that. And I was sending a panorama photo I had just taken around that time. Good to know.

I have the same thing happening but it's on 4G and 3G sometimes, usually it doesn't show any data transmission but just seems to stay on doing nothing for several minutes. Mine does stay on until I shut off my mobile network and when I turn the mobile network back on it stays off. With no text messages or anything going through.

Polling rate?

Is there a way to modify the wifi and mobile network polling rates? My phone dies like a dog at work due to no reception.
Thanks

Wi-Fi scan is a tweak in build.prop. There is a app called .prop tweaker or editor I believe.
Idk about network though

Whenever I'm in a poor signal area I just turn off mobile data and wifi. That way you don't have to worry about your radio constantly searching for better signals when your not even using it.

Yea just turn off data and WiFi. I saved HUGE amounts of battery doing that in bad signal area

I just turn my phone off completely. Great battery life, and I never have to worry about it searching for signal. Bonus: with all the new kernels popping up, when my phone is turned off it sleeps like a sloth.
Try it out!
Appreciate the replies but i use offline apps all day so i can't power down.
Anyone else know?

Battery drains while using data or wifi

this issue has been worrying me. if data or wifi turned off, battery performs decently, but when using network, the battery drains rapidly. here is my usage this morning (in china, on CDMA network) from 7am to 12am.

Wow that's harsh. Is there something running in the background that uses the data? Just a suggestion but I'm sure you already checked
If it continues maybe you could think about seeing if it happens on stock just to test. I assume your on a custom ROM because if the blue text in the status bar

GT-I9205 Orange/ee network, signal drop is becoming more regular?
Sent from my GT-I9205 using xda app-developers app
Many seem to experience this signal issue, me too. I have the i9205 international version. Tele2 network in Sweden/Sthlm. Its not always bad, but signal is significantly lower than the note 1 and note 2 I had before, most of the time. Still data and phone calls work good. Not too often I lose signal completely though, but more often than other models in same area.

I am losing signal completely with no texts or calls coming through........ it must be the phone, never had a problem with original note
