So I have found the answers to both the battery and the gps issues. The problem: fix for one is the cause for the other.
How to fix gps: reboot phone. Should get instant lock in maps.
How to fix battery: toggle airplane mode. Breaks gps locking. Reboot phone, breaks battery life extension.
I also believe the phone isn't reporting battery life properly. Had 11% battery when I got off of work. Toggled airplane mode to make it through the day. Plugged the car charger in and instantly was at 18%. Not a ridculous jump, but by the time I was home I was at 44%... which is pretty quick for a phone tha takes forever to charge.

If you use the "toggle airplane mode" workaround for the battery and reboot, you have to toggle it all over again. Takes a few seconds. This does not break the GPS.

Does on my phone. In order for me to get GPS, I have to reboot. As soon as I toggle Airplane Mode, GPS gone.
Edit: I think I see what you're saying. toggling airplane mode again worked for getting GPS back.

To be clear, there are two actions required for the toggle: Turn on Airplane Mode; immediately turn it off again.
Then, if you ever reboot, you need to do both steps of the toggle again.

I realize what toggle means. But when I was doing it, the GPS no longer worked (data back on). I did again and GPS worked again. So basically, hitting airplane 4 times.

I've already posted this on Android Central forums but have had no luck so I figured maybe someone here can help.
So this just happened to me last night. I was low on charge somewhere less than 15%. I plugged in my phone and turned it off with Wi-Fi and CDMA radio on. I turned it on a couple minutes later and it booted up in airplane mode. That's okay cause I can just turn airplane mode off. I do that and everything works fine BUT my lock screen still says "Airplane mode is on". If it matters I'm using the rooted Froyo 3.29 build that was released a little before the OTA came out.
Noticed another thing. When powering off it's going to airplane mode right before the screen turns off. I can see my Wi-Fi bars disappear and the airplane show up. Functionally it's fine but it kind of sucks I keep seeing the airplane when I press the power button even though it's no longer in airplane mode.
Has anyone else had this problem? Any possible fix to this?
EDIT:
Sorry. I realize this should be moved to the Q&A. Any moderators out there please move. Thanks!
Wifi Sleep when locked not working
Hello, I have a problem, my wifi sleep policy is turned on to "when screen turns off" but when my phone is locked, the wifi is still on! I just pressed the lock button after 5-10 mins but the wifi is still on.
How long does it take for you for the wifi to turn off?
Any suggestions?
Sent from my Nexus S using XDA App
Not a suggestion as such but I'm reading that using the wifi sleep policy is detrimental to the battery life. Can't confirm as I'm still experimenting.
Yeah battery life is destroyed if you use WiFi sleep policy. Set it to never for best battery life. It's counter intuitive.
But to answer your question, I think it takes closer to half hour for sleep policy to kick in. You would notice WiFi off if you woke up in the morning etc or after long periods like hours of inactivity.

I'm having the opposite issue. As soon as my screen goes off I lose WiFi connectivity and get disconnected on adbWireless which is a huge pain for me when I'm developing... Maybe I'll enable sleep policy and see if that fixes my issue! Lol! I'm on stock 2.3.1

There's an option in Settings>Application Settings>Development to not turn the screen off when charging, that should solve your adbWireless problem so long as your phone is charging.

this is exactly how it works on the Galaxy S
there is an option in settings to keep WiFi on when the screen is Off in the SGS
but not sure if the NS has the same option (still waiting for my phone to arrive)

I went to my wifi setting to make my wifi sleep once my screen shuts off but the setting doesn't stay. Is there a fix to this by any chance? Want my wifi to always sleep when my screen shuts off......

What do you mean it doesn't stay, it changes the setting to something else? When you have wifi set to sleep on screen off, it doesn't sleep immediately once the screen goes off, it takes awhile. I use "sleep when screen off" and I get great battery life.
Wait so is it good that my wifi turns off when my phone sleeps or not?

it depends on what you want
if you want to maintain connectivity then it's no good
if you want to save power, then it is good

Once I turn my screen off than turn it back on after a while my setting goes back to never even after I change the setting to shut wifi off once I shut off screen. Weird bit it does. I read in another forum that it saves battery but my setting keep changing back.

I've the same issue. I've try various app from the market for fix that, but all is the same. It's a hardware problem? The router will can cause this problem?
Thanks
So a few weeks ago, I noticed when my nook reboots, it does not automatically turn on the wifi. I have to do it from the settings area. If I do it from the notification bar, it doesn't work so hot. I put on green power today to see if that would help me flush out the issue and, even though wifi is on right now, green power is insisting that the airplane mode is on. If I set airplane mode on in settings, it does turn off the wifi and it sets in a state where it says "disabling wifi connections". It never toggles over to a check being there for airplane mode and giving me control. I have to back out of the settings and come back. When I do, airplane mode is not visibly listed as being on. I can turn the wifi on and green power insists airplane mode is on. If I reboot, sure enough, no automatic wifi.
Any ideas? I've got CM-7 08042011 running.

Magnetron1 from the cyanogenmod forums has a way to avoid this. Go here and find the most recent nightly he modified. I believe it's cm7 nightly 251. He named it cm7 nightly 251m*. That did the trick for me. I've been downloading my nightlies here ever since the airplane mode issue appeared.
Download android assistant from the market and then uncheck airplane mode.

This worked. It had an airplane icon down in blue and when I clicked it, green power finally has said airplane mode is off. Hopefully wifi will be on by default now when it reboots.
Edit-confirmed working. When nook reboots, wifi now defaults to on again. Awesome!

Try this, not guarenteeing it shall work however,
Turn off airplane mode, THEN turn off wifi, Shut the phone off. Then turn it on again. It might refresh the settings
work but if i enable airplane mode, and i use wifi, then again when i disable airplane mode wifi go on automatically again

Ok, so to clarify,
START
WIFI: OFF
AIRPLANE MODE: OFF
you turn on airplane mode. Then turn on WiFi
You use your wifi and then shut it off. Correct?
THen you turn off airplane mode and your wifi comes on automatically right?
exactly right! wifi come on automatically in the last step

I think when you turn off airplane mode it basically restores the settings you had before you turned it off. Try doing exactly the same steps with bluetooth and see if it happens, if what I'm guessing is correct then you can do the same thing and when you turn airplane mode off bluetooth will turn back on.

yeah that's what I was trying to figure out, I know if WiFi is on and I enable airplane mode, it saves that so when I turn airplane mode disabled, it restores the WiFi. So shut WiFi off before enabling airplane mode

Kl thanks for confirming that. @OP as long as you aren't using a Froyo build or an AOSP GB build, you will have the option to have the quick controls in the notification bar. Make use of it, it saves so much time. Drag down, tap the wifi icon THEN the airplane mode icon and you're all set. Even if you forget to turn wifi off before turning on airplane mode, using this you can always turn wifi off very easily afterwards anyway
so i can't enable wifi during airplane mode is on? it's a android bug i thing!

No, you CAN enable wifi when airplane mode is on, but before you turn airplane mode on turn wifi off. Anyway, I don't see how difficult it is to turn wifi off afterwards? Literally drag down the status bar and tap the wifi icon and you're done.
but i do this exactly and wifi return on when i disable airplane mode
wifi nexus 7. turn on airplane mode. manually turn wifi back on. what stays off, anything? GPS? Does airplane mode have any use or advantage on a wifi only device. Any battery use changes or background processes that stop? Thanks for any responses

Probably no bluetooth, either. I know it turned it off on my old work blackberry because it was on the same screen and you could see it turn off.
It should turn off EVERYTHING wireless. That includes, to my knowledge, WiFi, GPS, NFC, and Bluetooth.
It should help with battery life - although probably very slightly. GPS/NFC/Bluetooth truthfully have very little effect on battery life as is, and WiFi isn't that big of a hog. But it certainly could help to eek out an extra few percentage points if you *really* needed it.
