Data on when on wifi

[amirage]

Hi,

Just wanted to ask: Is there a significant difference in battery usage with the data on while on WiFi? I had read somewhere that it's best to turn off data when on wifi so that the radio doesn't keep looking for 4g signals unnecessarily thus saving battery. Has anyone tested this? But, generally, I wanted if this theory is just a hoax or if there's some meat to it!

Hoax. WiFi uses more energy than data

My phone doesn't use LTE/mobile data when WiFi is working. When I turn WiFi off, it takes a second to reconnect to mobile data network and show the icon up top. I assume it's not working in conjunction, I also believe it won't affect battery life one way or another.

If you have a very poor signal, it will most likely be searching. However turning off data won't stop this (at least I don't think it will)

Cool thanks..

I don't know if turning data off will result in battery savings but I have been using Tasker to automatically turn my data off when on WiFi for the longest time now.
