iPhone 5 - WIFI Cuts off when locked

[Damolee]

Hi folks,

First few days of having the phone, everything was great.

Now, when I lock the phone the WIFI basically disables itself. I can tell because when I push the home button, the icon at the top re-appears.

This is pretty annoying because I use iMessage a fair bit and 3G signal seems to absolutely wreck battery life when I have a poor signal (so I keep it disabled)

Effectively, when the phone is locked things such as push mail and notifications have been deemed useless.

I thought persistent WIFI was something iOS did these days?

No. You thought wrong.
Wifi always turned off to save battery when the screen is off and locked.
Push and iMessages will work fine with carrier data.
Stop turning off 3G.

It also has the potential to use up a TON of data if you are receiving a lot of emails when the phone is locked and using data.

I also just noticed this problem on my iphone 5. Im hoping there is a fix to this. When I connect to a wifi network, I want my phone to always be connected to that network, until I either leave the area of the network or disconnect from it.

I'm pretty sure the WiFi kicks back on as soon as data traffic is starting to occur. Unless it's something as small as an iMessage which would be completely transferred by the time the WiFi had a chance to try and reconnect to the network.

There is no fix cause its not broken. That's the way it was designed and always worked since the original iphone.
You can turn off push emails and just check them whenever you want. that will save you TONS of data

When data is disabled the Wifi should remain active. That is my understanding of it.

Wifi will always cut out when the phone is in sleep mode, with one exception, if the phone is connected to a live power source wifi remains active when the phone goes to sleep

Sounds like a pretty dumb design then, if you ask me. Why would I want to use LTE data if Im purposefully connected to a wifi network?

Also VPN got disconected when phone is locked....

To save battery. You wont use much data if you disable push emails. All imessages and push notifications will use a very few kb's of data so that's very minimal carrier data use.
If your iphone stays connected to wifi all day even if the phones screen is not turned on or then you will kill your battery very fast.
Like the user suggested if you keep it plugged in then it will maintain the wifi connectivity even when it goes to sleep mode.

I love all the comments about saving battery. Using wifi uses much less battery than cellular data.
