Every time I open an app that leverages GPS (e.g. Facebook), the GPS icon flickers and shuts off WiFi, is this normal..? Very annoying to disconnect randomly.

I just tested this out with Maps and I'm not able to reproduce (I'm on CleanROM DE 3.1). I notice that my data connection flicks on for a second (most likely to get a rough bearing on my location while GPS is still searching). WiFi is still undisturbed though.
I am still on stock right now, my WiFi turns off completely (bars disappear) and loses connection before reconnecting.
I can also emulate this on Maps.

I saw several posts suggesting that leaving WiFi on where you have WiFi connection helps you to save the battery which I'm finding pretty strange. I thought WiFi actually drains battery faster then anything else. Are savings due to the fact that WiFi is more efficient then 3G or does it actually holds true that it saves battery?
All things being equal, Wi-Fi uses less power than 3G. Wi-Fi radio waves don't have to go as far, so they're easier to generate. When Wi-Fi is on, 3G is off, so you'll save power if you're actually transferring data.
A lot of programs will initiate data transfers by themselves when connected to Wi-Fi though, so perhaps that is why some will notice higher drain when Wi-Fi is on.
Also, if Wi-Fi is left on and you are on the move, your battery will drain since your phone is constantly searching for available networks.
Unless you've changed the settings, however, when your phone's screen it off it switches back to 3G to handle data.

This however, is untrue. At least for me. I run the leaked 2.2 and my WiFi is always on at home, my data connection is never active. I check this by dialing *3282# and hitting send.

When I have wifi switched on I lose around 5 to 10% an hour. With it off I lose 1 to 2%. I don't have anything set to sync differently via wifi. I only have a few apps that sync data and those are set to do so every 4 hours or so.
I have tried leaving it both on and off overnight to test this and every time I've left it off I woke up with a full battery. If I leave it on I have to charge again in the morning.
When I'm going out I turn wifi off so that my phone isn't constantly searching for signal.

In the Wi-Fi advanced settings (Hit Menu when in the normal wi-fi settings), there is a Wi-Fi Sleep Policy (which specifies when to switch from Wi-Fi to mobile data)
By default, my device was set to 'When screen turns off'. the other options were 'Never when plugged in' or 'Never', I switched mine to 'Never'. You should notice that when you turn your screen on, the wifi icon doesn't show up right away. Of course, I'm on 2.1, so this may be different in 2.2, but check it out.
For me, I get no cell signal in the building at work so I need to keep wifi on. If I turn it off my battery drains fast from the 3g radio constantly trying to lock on a signal.
It depends in the quality of your 3G connection, but all things equal I have seen that using WiFi instead of 3G does save battery, when the WiFi is connected of course. Anytime a radio is constantly searching for a signal or trying to hold a weak signal, power usage tends to go up.

Check out Y5 Battery Saver.
This app turns your wifi on/off based on the cell towers that you are on. You just connect to wifi, enable the app, and it remembers what cell towers you were on while you were in range of that wifi location. as soon as you are off of those towers, it turns off wifi. to add new wifi locations, just disable the app, connect to the hot spot, and re-enable the app.
This gives you the best of both worlds. you get to save battery while you are using wifi and when you are out of range it doesn't continually search for new wifi networks to connect to.

Whenever I turn my screen on, my wifi icon is right there. No delay in it showing up. I don't remember ever changing the sleep policy when I updated so I believe this is the default behavior for 2.2

+1 on Y5. There are a few other apps in the market that claim to do the same thing, but I think Y5 is by far the easiest to set up and works really well. Nice little utility so you don't have to keep remembering to turn off the wifi manually when you are out of range.
Now if I could just find a app that does the same for my bluetooth when it is near my car....but that I think is much harder to do without it actually polling.
Hello all,
I'm having this problem with my HTC Desire S.
Everytime I start an app that uses my GPS, and tries to get a fix. Like maps, runkeeper or GPS Status. I lose my data connection.
I can go to my settings then. And in my settings its still turned on, but I dont have the little icon on top, neither do I have an internet connection.
I can turn off my data connection then, en turn it back on. And then it reconnects again, and both my GPS and data connection are working.
Untill I exit the app that uses my gps, and if after an hour or so I use my GPS again, the problem repeats itself.
Anyone else had this problem and / or know a fix for it?
I've used the search, but nothing came up.
Hello,
I had the same problem but it resolved with GPS TEST application from market.
Turn on GPS and mobiile network then run app Gps Test and from settings menu clear a-gps then update Gps and wait to lock gps to satellites.
After that you can use some navigation software such iGO, Sygic .. and so ..
I solved my problem with this way.
Have any skyrocket owners run into issues with the GPS? Over the last few days I've found that the GPS radio is very hit or miss, & more often miss than not.
I typically leave the GPS radio off, enabling it when I need maps, navigation, yelp, etc.On my original GS2 this had worked without issue ... after turning on the radio I'd have GPS functionality within a few seconds.
On the sky, though, Google Maps, Places, etc report "waiting for location" for several seconds; then Maps times out with no result while Places errors out with the message "your different location is temporarily unavailable" ... this even after the GPS radio has been on for 30+ minutes! i've had this result whether I'm inside our outside.
Fwiw under location services I have UseWiFi OFF, Use GPS ON, & Sensor Aiding ON.
I should mention that SOME times out does work, though I've not found a pattern.doesn't appear to be battery related, since i've had it not work at full charge, then work later that day at 5% charge.
Too I downloaded the GPS Status app to directly see what result the GPS radio was returning ... that app shows the GPS properly returning a latitude & longitude, but then exciting the app & trying Maps still gets no GPS/location result.
I also get this issue, so is it a map issue or a gps issue? cause I will go down to ATT and return this *****.
My GPS works great locks almost instantly indoors or out. Infact its by far the best of any phone i've had yet.
I've been having the same issue. Mine has trouble locking my coordinates for minutes at times. I will run the GPS Test and it will look for towers for minutes at a time and it takes forever for it to update the clock and get a Long & Lat fix. To fix it, I have to toggle the GPS button and sometimes it works and other times I end up having to reboot. Yesterday while driving and using the maps, it lost the signal while enroute and wouldn't pick up another signal until I rebooted.
It's quite odd ... when I was traveling in Portland last few days, the GPS issues were often and persistent. Get back home to SF, and suddenly GPS has started working w/o issue, try as I can I can't get it to reproduce the problem now ???
I don't seem to have any issues with the GPS on my Skyrocket. It usually locks on within 10 seconds and is accurate.
I have a reoccurring issue of losing cellular signal whenever I run applications that use a constant GPS and data connection. For example, I use Glympse almost daily, and I find that after 10-15 minutes Glympse reports "no data connection" and my 4G LTE symbol is replaced with the no signal (circle w/line through it) symbol. I cant get phone calls, texts, data, nothing. This seems to happen with any app that uses GPS and data like Glympse, Google Maps/NAV, Navigon, etc. If I use an app that just uses data (Pandora, Sirius, etc) with no GPS the connection is solid and I have no issues. I am able to get the connection back by turning on airplane mode then turning it off again. If I just leave it, the connection never comes back, until I turn on airplane mode or reboot.
Has anyone else seen this issue? Hoping that a fix or ICS comes out in the next couple months that will resolve this. Between this and the screen issues I am thinking about taking it back when the Note is released and seeing if they will let me swap it out.
Hello there.
I am facing a problem which i think is caused from the bt.
Everything works fine (no battery drain, no heat, not lagging, no crashing apps, perfect voice quality etc) EXCEPT when i connect my bt headset(-s).
At first it works fine, make my calls, download emails browse everything. At some point (it could be 5 minutes it could be 5hrs) i am facing disconnections with the connected bt device. The phone may or may not show it is disconnected, it may or may not enable voice through bt (but i cannot hear anything). During the call i can toggle bluetooth and speak through the phone.
Here is the chain of events.
After this it drops the connection with the wifi and the menu stays at Searching mode (i left it in search mode for >5hrs with no luck discovering any wifi). If i disalble wireless or bt or enable/disable airplane mode the menu stays grey forever and with the dots in the upper screen keep coming and coming. Long story short i cannot toggle on/off any connectivity feature (only cellular data works under any circumstances), i have to either turn off and on the phone or soft reset it. I did two hard resets (one of them was clean state) but this behavior hasn't changed.
Also if i have only bt on and connected and i leave it overnight in the morning it shows about 10 - 15% battery and quiet hours are not auto disabled (also tried to turn Cortana Off) BUT if i plug it for FIVE minutes it goes back to 90-95%. and have normal battery consumption during the day.
The only thing i havent tried (and if i do i will do it only for testing reasons) is roll back back to WP8.0.
Am i facing a warranty issue or is it a glitch of the software (i am running Cyan)?

I got the exact same problem with my own L1020, have been fighting with support to have it fixed, they changed about everything (except the mainboard...) and the problem is still there.
I started to be really angry and got a free Lumia 930 in "replacement"... as I still got the L1020, I tried to put it under W10 preview, and it looks like the problem is really a software issue... with some builds, Bluetooth was working fine, with some the same problem appeared again...
I don't know if you found a solution in the meantime... if you did, I'd like to know what it was, because I like the 1020 better than the 930 (size and camera mostly) and I'd love to have it working with my MS Band
