iPhone Phone switching to LTE when asleep

[NovemberWhiskey]

This was a problem with 6.0, and was fixed by 6.0.1 for me a long time ago.

I'm on the newest 6.1.2 jailbroken via Evasion, and every time I wake my phone up, it is on LTE, and switches back to wifi after 1 second.

Anyone else?

I remember the battery savings being great after they fixed the wifi bug in 6.0.1.

It turns off wifi while sleeping - that's normal behavior.

Yep, its been like that since the original iphone back in 2007.
Always shuts off wifi when the screen locks. Unless you have it plugged in to charge.

If it didn't you would have no battery life

Really? I could swear this didn't happen before on 6.0.1.

Well, I guess if it is normal that is fine. I don't know how switching to LTE saves battery life as opposed to staying on wifi (unless it is turning off all radios), but I'll trust you guys.

I've tested it several times and it only does it sporadically. Sometimes I wake it up and it is still on wifi. Unless it is just showing that, while actually not.

I dunno.

It stays on wifi while it is connected to power, but it has a timer for turning wifi off.

If you do want to keep it on while asleep you can get Insomnia on cydia.


I also don't get how it saves battery. While I'm at home, it seems like since wifi uses less battery that it would use less power to keep it on and use wifi, but it has to use cell data to get calls/texts so it would have both on. So when you actually think about it it does make sense that it saves battery.

One radio always powered on is less taxing on a battery than two radios always powered on.
