It sounds odd- how can your wireless scan when its already connected. Does your wifi status say - connected?
Either install superpower app from the market. It will make sure that your wifi doesnt drain your battery or you can install OCLF 2.0 from market and tweak the wifi settings to ensure longer battery life.

It does not scan when connected to a wifi, only when you open the wifi settings page, so it can present you with an updated list.
Concerning: possible reasons are low signal strength or a rom variant which uses a lot of power, JPY for example. One solution is to exchange with other wifi driver. Some custom roms offer less powerhungry wifi.

Settings wifi scanning off when screen off or similar .

I read on the Darky's ROM thread that this is normal android behaviour but yes it seams weird to me too.

[Q] Turning off 3G drops USB connection

HTC UK O2 NoDo and unlocked
Odd behaviour. I usually toggle off wifi,bluetooth, gps and data to save battery if I'm away for extended periods and speed up charging since you can't turn off the phone if connected.
1. Whilst USB connected. If I leave Data Connection On and turn off 3G. USB disconnects and orange LED turns off. No charge or sync with zune within 1 minute.
2. If I leave Data Connection On and turn off 3G before plugging in. Same thing happens. Again within 1 min.
3. If I leave Data Connection On and leave 3G On. Stays connected and charges/syncs with zune without any issue.
4. If I turn off Data Connection completely. Stays connected and charges/syncs with zune without any issue. But if I toggle Data Connection On whilst plugged in and 3G still off..again in 1 min it disconnects.
It is as if I toggle off 3G prior or after plugging in USB to a PC. Connection drops after 1 minute but not straight away.
Not a big deal. But curious if someone else could try the above scenarios, could be a WP7 OS thing, could be device specific or maybe I put too much homebrew apps and registry changes screwing it up.
Let me know you experience same thing! Many thanks

TMOUS HD7 here, no connection drop with 3g on or 3g off, even when i toggle while its connected to zune..I'm guessing it must be something you did to your registry..

[Q] Wifi and Data disconnecting during deep sleep

My HTC Butterfly S has been disconnecting from wifi whenever i leave it alone for some time (10~20mins). Whenever i on the screen after such times, i realise that there is ABSOLUTELY no data or wifi connection (only the signal bars icon are in the status bar) and 1 or 2 seconds later, LTE reconnected and then wifi reconnected 1~2 secs later itself too.
I tried sending links from chrome to my phone (using sendtab) during this period and the phone does not receive any notifications, thus confirming the fact that there is no internet connection whenever the phone is in deep sleep.
Oh and 1 more thing : this only happens when wifi is connected, if wifi isnt connected when the phone goes into deep sleep, there is still LTE connection. When wifi is connected and the phone goes into deep sleep, the phone does not default back to LTE or 3g, all forms of connection with the internet are gone, only leaving the cellular connection available.
Anyone having the same problems? Btw phone is bootloader unlocked and rooted, using stock rom.

Check and make sure your power saving mode isn't on

Nope it's not on, and wifi is also set to always on during sleep.

Probably it's how the Rom is built to save battery

Actually, I don't think that power saving mode disables the connection, but sleep mode, that is enabled on my phone in Power option. From description it disables any data transfer during deep sleep. I have MaximusHD rom, can't tell if that option is shown on stock.

Try disabling this option :
WIFI > Advanced > Wifi optimization
This option might be the cause. Also, you might want to tick the Best Wifi Performance to test.
It's natural for android to silently disable data when you're on wifi. It only makes sense to do that.

Toggle between WiFi and mobile data with tasker

Hello. Does anyone knows how to make a script for tasker which switch mobile data off if WiFi is connected and mobile data back on if there's no WiFi connection? For the last 3 or 4 hours I'm searching for this and can't find nothing.
Also, I want if there's no WiFi network, to switch WiFi off (so mobile data will be turned on).
I managed to do something, but it didn't worked. When I enabled the profiles with WiFi and mobile data both turned on, the mobile data turned off, then WiFi off, then mobile data on and so on, in a loop.

Wouldn't that be redundant? The os already does that.

Thanks for the response. I know that if WiFi is connected, I'm using the internet from it, but mobile data is still active, right? Even if there's no traffic from mobile data, that's still on. Wouldn't that be a source of battery drain?

I set my data to turn off if my phone is connected for 5 minutes to a wifi. Important: set collision handling to 'abort existing task'.
Here you got pictures.
Edit:
if you are further interested in battery savings, you can read my thread "[BATTERY LIFE] How to get up to 7+h of screen-on-time"

This is absolutely redundant and unnecesary, when the phone connects to a wifi, it disables 3g/LTE data connection by itself. When you connect to a wifi you can see how the 3g/H/H+ icon above radio signal dissapears. The radio chip inside this phones can be used in Wifi mode or 3g/4g mode for data connection, but not both at a time. It is technically not possible.

The moment you don't have wifi anylonger, the phone starts a fullburst search for wifi and 3G/4G networks (even if I don't want wifi/data at the moment). and this drains a hell of a lot of battery. then (if you go out e.g.) it finds a 3g/4g-connection which it tries to keep up (drains a lot battery) and in the same time searches for wifi-networks (also drains battery)... very inefficient use of battery
So I deactivate data after 5 mins automatically via tasker and turn it on manually when I need it (could also automate that, but I'm lazy). This way I circumvent all these battery drains
Additionally:
Under normal circumstances I'd also set wifi to "turn off if not connected" (in settings) and "optimize wifi for battery life", but I use a custom stock kernel that has issues with these settings so I need to leave wifi on all day

Umm, ok... But this has nothing to do with what the OP asked, or what I said.

You may try e-robot from play store.
I have a command for that, after wifi disconnects, wait for 30 sec. If still wifi is not connected, automaticcaly disables wifi.
Same as for bluetooth. When i leave my phone in my desk and gone for a while, 60 sec later disable bt.
You can do what ever you want.

Wi-Fi Always on even outside

Hi,
I have a question to you guys maybe somebody can answer this, i tried searching for an answer already but found no answer.
I have the P30 Pro and checked the battery usage and i see the Wi-Fi is always on even when the screen is off.
I attached a screen shot, the odd thing is that i was the whole day on the beach without Wi-Fi coverage.
I know that there is the always scan feature but it is already off.
Any ideas as to why this happens?
Any feedback would be appreciated

So, you had wifi turned on while at the beach, but it wasn't connected to a network, correct? My understanding of the Wifi Scanning option is the act of scanning for wifi hotspots for the purposes of location determination. If your wifi is Enabled on your phone, it's constantly scanning to try and connect to a network you've saved. You could turn off the Stay Connected When Device Sleeps switch on the battery settings, but this would affect your cellular connection in addition to wifi as I understand it.
If you don't want to have wifi draining your battery while out and about, you'll need to turn it off. If you did turn it off, then I've got nothing...

When you don´t use a battery saving option and leave Wifi on it will stay on, regardless whether you have a signal or your screen is turned off. That´s the way it should work.
