[Q] Wifi Sleep Policy

My wifi sleep policy wont persist. I change it to 15 minutes, then maybe a half hour later its set back to never. Running dk28 frankenstain vd25xxx. Does anyone else have this problem or a solution?

Why don't you want to keep it at never?

I had that same prob on my hero. Might be an android thing?
At any rate, you want it on never.

Id like it to switch off if I happen to be not using my phone for a bit. After a few hours of leaving it sitting, and its still connected to that wifi connection, it kinda hurts the battery.

Actually your 3g radio uses more battery than wifi unless your wifi signal is weak and your 3g signal is strong.

gets hot and saps power

Every so often my galaxy nexus will just get really hot in my pocket and start draining battery like crazy. I stopped all the apps and processes and the battery was still draining. I even turned the phone off but when i turned it back on it just got really hot again and the battery was still plummeting.
I'm pretty sure this didnt happen before I got the 4.0.2 update but might have nothing to do with it.
I even got 2x battery to see if it helped on some useless processes that might be causing it and I though it worked as it didnt happen again for a while... until yesterday.
This happened to anyone else or have any idea what it could be?

You need to more specific, Are you rooted? overclocked? pure stock?...something is causing it to run this way either that or your pure stock nexus could have a defect..any device getting hot is causing stress to the battery and hardware,which over all long period of time will most likely cause the device to break...
Sent from my Galaxy Nexus using XDA App

oh yeah. Its just pure stock

pull the battery out for like 10 seconds...and power it back on,and clear all recent apps..what is 2x battery a app?..or do you mean the extended battery?....

I usually reboot after a update ..just to make sure settings are reset and working properly

Usually this is due to a rogue app. Use the built-in battery monitor as well as BetterBatteryStats to identify the app and remove it.
BTW, it's the battery drain causing the phone to get hot. Heat, by itself, will not cause battery drain (not on the timescale you're talking about at least). Just a cause and effect FYI.

clear all recent apps? i turned it off and back on. i shouldnt really need to take the battery out should i? but then after a while it stops doing it??? like when i plugged in the charger.
2xbattery is suppose to be a battery saving app

when i went to the battery monitor it just said the main battery use was exchange services, screen and OS not much else.
plus when rebooting the phone shouldnt this have stopped the "rouge app"?

Some apps will start themselves at boot. A reboot will thus not solve the problem.
As for exchange, what are your settings? Push, or poll? If poll, how often? Are you still getting email?

Yeah im gettin email its on push. It only happens now and again tho, not all the time. Plus the battery saver is suppose to minimize checks and stuff

Is your phone holding signal? My phone only gets hot when it can't find and hold a signal.

This could actually be a possibility come to think of it. Every time its happened I was in a place known as "the bat cave".
Is there any theory on this?
Sent from my Galaxy Nexus using XDA App

Its possible that exchange services was top of the battery use list actually. Would this have anything to do with searching for or holding a signal?
Next time it happens I'll try closing exchange services to see if its that or if it it is I'm not getting a signal I'll try putting it in airplane mode to see if that stops it.

[Q] Nitro as WiFi Only phone

I am looking to buy the Nitro HD for WiFi only use and maybe occasional prepaid use. I will flash to some deodexed ROM or maybe CM9 so I am not so concerned about software issues in the stock ROM.
What I am more concerned about is - how are the cameras for Skype/Google Video etc?
Any way to turn off all radios except WiFi by default everytime the phone starts up?
Thanks.

^^bump^^

I'll chime in here, I use mine as a wifi only device. As far as Skype/google video goes, video calls are great. I don't have a Sim card in mine and the mobile settings are greyed out which I'm assuming the cellular is off.
I'm currently running the latest cm9 nightlies and the device keeps getting better and better.
Battery life is definitely better than gingerbread. Battery life is within reason for a device this powerful while on wifi. The only battery drain I've found is being out of range of a wifi area. It seems the device goes on over drive looking for wifi and within an hour, majority of your battery is dead. This might be a CM9 issue, I'm not sure on that. Just remember to turn off your wifi when out and about.

Thanks for the response. I got myself a used one for $200 today off Craigslist. Will put leaked ICS ROM on it
Looks much sweeter than my iPhone 4S!!

UP！UP!
The super screen is eye candy. Using wifi it will last for 5-7 hours, while using 3g only for 2-3 hours.
For these two reasons, i often use it only as WIFI.
Will somebody introduce a super airplane mode without shutdown of WIFI？

Get dx battery saver, put it into sleep mode, then activate wifi.

You don't need any special app. Just enable airplane mode, then enable wifi.

oh,no, it is a two-click thing with a wifi interruption.
We want a one-click button.

I got it！
If there is /system/etc/settings.xml, modify it about what is airplane mode （this is, remove “wifi” in the lines of "airplane-mode" ）.

[Q] GPS seems to be constantly cycling on and killing my battery

Has anyone been having issues with their GPS this last week? Mine seems to constantly cycle on and drains the battery wicked fast. I turned off location reporting in latitude and that didn't help. Not sure what is causing it and if there is something I can do something to fix it or not.. Any ideas? gnex CM 10.1-20130404

Switch GPS to OFF, unless you are using it.

Wifi drain battery

I have a problem with wifi. In battery stats wifi has more consumption as screen.
I never seen it on any other android smartphone in my house.
Somebody with this behavior? I am using latest stock.

Check Location>Wifi Scanning

any other idea
thx, i disable scanning in location, reboot, after week still wifi 1st in battery consumption, it's not big problem, battery life on this phone is excellent, but can be better

It's a wrong report from Android, your WiFi is not draining your battery (a few of us have the same problem, me included). I don't know where it comes from but you can just ignore it (there's no real way to fix the issue I'm afraid)

Mine was doing the same - and I use Chrome a lot for web surfing
Disable Location permissions in Chrome (Settings->Apps->Chrome->Permissions->Location Off)

ok, i just ignoring it, not big deal, battery life is fine, i just was wondering if can be even better everybody know android is quite tricky

Some screenshots would be great, so people can help.

That's the kind of problem he is having, which is just a bug from Android ?

I hope you have your WiFi scanning and WiFi network notification off.
I faced same problem in the starting.
I switched above settings off and cleared cache and then switched off WiFi and restated phone.
Now it is gone. Hope it helps.

Everything has been off for a while, the "problem" appeared afterwards but I personally don't mind, I know that's just a bug

Are you guys only seeing this reporting when wifi is on but not connected? Or all the time?
Only had the device 2 days, but no sign of it for me - wifi on, background scanning and network notification also on. Only been out of wifi coverage for a few hours though.

It's when the WiFi is on (connected or not).

OK, some say it's a bug, others say it's no biggie since the large battery, but.... I used to get home after a 12 hr days work, and have 4-5 hrs sot and still 20-30% left. Now I need to keep the phone charged, because it's down to 10 % halfway... That IS a BIGGIE.... And for those who say it's just a stats thingie, well, if this thingie shows 0%: your phone WILL shut down!
Ive tried ALL tips, NOTHING works. Period. What bugs me most is that I don't know why! I turned off scanning, cleared cache, reboot, etc, heck, I even did multiple factory resets, NO GO on any of those!
Believe me I'm happy for those that have solved the issue, but this should have never happened.
After consulting Motorola's customer services I was advised to send it back for repair, and so I did. I need to get it back still, but if this really is a bug, than:
SHAME ON YOU MOTOROLA/LENOVO.
You need to fix this asap, because it really IS a BIGGIE!

Even when it was disabled all the time.

you have to disable location scanning for bluetooth and wifi. I've had the same issue. I also dont use high accuracy location. I use device only to save battery and prevent wifi from turning on. It drains crap ton of battery.

Yea! I had also disabled it and made one thread for this so let other knows the solution.
