Screen on with no reason and battery drains... - Acer Iconia A500

i have read an old thread with a similar, not solved, problem, but i didn't wanted to write in a so old thread...
so...
when the wifi radio is on, my iconia a500 suddendly turns on the screen and it stays on also for various minutes, sometimes i guess also until the battery is completely finished (i have found more than once the tablet off because of battery drained in the morning, so i guess it was with screen on all night long)
this happens also if i set wifi to go off when display is off.
i have tried many different roms (taboonay, lightspeed ... and now i have thor rom 14.2, installed yesterday) but the problem is always here.
if i manually turn off wifi, this seems to never happen... or at least it never happened while i was watching the tablet during the last months
does anybody knows a solution, a hint... or anything that could be helpful to make this issue less annoying?
thanks!

You might have a program installed that is constantly calling for wifi access?
That's the only thing I can think of?
On my Rom, I haven't ever experienced that problem.
My settings are as follows:
Airplane mode on
Wifi On
Wifi disconnect policy: when screen turns off.

also when i just turn it on it happens, even with no services or program needing wifi...
but you gave a me a good idea to try...
i will put airplane mode on and check what happens now
and anyway, i'll check again my programs

For me it is quite common....
To check it i keep it next to the tv while i watch it, or next to the computer

If airplane mode is turned on doesn't that over ride the wifi on setting?
So if airplane mode is on wifi will always be off so the disconnect setting has no bearing.
Can someone please confirm above or explain..
thanks

no, you can put airplane mode and then turn on wifi
and seems like it is working well... but i don't want to talk too early...

Airplane mode is for tablet/phones with data connections. Airplane mode just turns that off

Yes, but for some strange reason it helps with the wake up problem some have

That's what I was getting at - when airplane mode is turned on it overrides all other settings and wifi can not be engaged in any way until it (airplane mode)is turned off.

Yup I was just answering Spud
Airplane mode only refers to the 3g/4g cell radio (so it turns off wireless network data/phone calls/texts etc.). You can still turn on wifi and use it when airplane mode is on because this is a different radio (well in the a500 there is no 3g radio). After all many airplanes now have wifi on board, however you're still supposed to have it airplane mode.

Thanks.
I haven't been able to turn in wifi with airplane mode on - it takes a longer push (hold) on the wifi button to engage.
I now have wifi on with airplane mode on - didn't realize airplane didn't also disable wifi.

Incorrect! You turn Airplane Mode on, which turns off wifi, then turn on wifi with Airplane Mode still turned on (and airplane mode stays on with wifi turned on as well).

after some days trying i have noticed that putting in airplane mode solves the problem...
but not always the tablet turns off wifi and stay in airplane mode when i turn off the display, it is surely some annoying app (or widget) that makes this happen.
i'm trying to understand which one

The only way to do that is process of elimination. Knocking out the variables one by one until you find the culprit, which has the potential to be a long, painstaking process. Start by uninstalling, one by one your apps that require internet access, and wait a couple days In between each one to see how your tab reacts.Then again, it may be an app that you wouldn't think needs wifi access to work, but in the background is calling for access.
Good luck with it!

N1 data connection issue... please help!

Hi everyone, I had a quick question I needed your assistance on.
Sometime I put my N1 into Airplane mode to save battery and when I finally turn airplane mode off I can never seem to get a data connection unless I totally shut off the phone and turn it back on again. Coming out of Airplane mode there will be a 3g signal on the status bar but only the up arrow will light up and anything needing data (browser, market, etc) wont work unless I totally shut off the phone and turn it back on again. Is this happening to you too?
The same thing happens if I open up the Quick Settings app and turn off mobile data (to save battery) and when I turn mobile data back on I have to restart the phone entirely for it to work properly.
It seems like my phone might be having an issue with data connection so I might have to call up HTC about it but I wanted to find out from the other members on the forum if this was happening to them too.
Thank you for your help
It's happened to me before using APNdroid.
Apparently you can fix it by turning the radio on and off in the testing menu (*#*#4636#*#), never tried it though.

Lose service, it never comes back

Lately, I've been having an issue where if I go into an area with no service (or at least I think I have no service) I never get service again, even when I'm in areas where I know I have strong service. Sometimes if I go into airplane mode and back, it comes back, sometimes it doesn't, and sometimes when this happens, and I turn on airplane mode and turn it off again, the phone shuts itself off and I have to manually power it back on.
Anyone have this issue, or know what could be going on?

I have this same issue myself. Dunno what it is and wasn't able to fix it either. You can look through my comments to find an identicle thread I started a couple of days ago on this same issue titled "Data connection issue" to see if it helps.
I'll have airplane mode on for awhile but when I finally turn it off I get 3g data showing in the status bar but only one of the arrow's will light up if I try to use the browser and eventually sputters out. Same thing would happen with the Quicksettings app when I would turn off the apn data toggle for awhile, when I turn it back on there is no real data connection even though the 3g is showing...
I've tried the whole thing about pressing the #4#... etc to turn off the radio and turn it back on again but nothing works for me. I wish someone knew how to fix this
mine does the same thing. the only thing that works for me is turning it off and back on again. such a PITA.
mine does it also
I fixed my similar 3g problem by (re)flashing the radio from recovery.

I'm hoping that Froyo finally brings a fix for this (and full Exchange calendar), or it's Craigslistville for my N1.

This or a restart will always fix the problem when this happens to me.

WiFi Sleep Policy Issue

So I set the WiFi sleep policy to "Never when plugged in".
I.e. screen off = wifi off (on battery), and screen off = wifi on (on charge/plugged in).
Just want to save battery, even though battery life is already pretty good, especially coming from my 'charge every night' HTC Desire!
Problem is, it decides to change itself to "Never", even if I am not using the tablet. (checked by going back into the setting and finding the "Never" radio checked.) Can anyone else verify if they have the same issue?

same here, no problem setting up a different policy
Thanks for the reply.
For me it seems to change by itself after quite a while. (like overnight)
So, have you always had yours on a policy other than 'Never'?
So I've decided to set mine to the same setting and my setting sticks. However when mine does go to sleep on battery and I wake it up, sometimes it never reconnects to the wifi or rescans. So I am forced to turn off wifi manually and backon for it to reconnect.
Anyone else ever have that issue?

you need to set your wifi setting to Static IP instead of DHCP. This will resolve your issue. I had the same issue and now its fixed.

Seems to be a common problem for any device with a Broadcom 4330.
Broadcom's policy towards open source has always sucked, and crap like this is the result.
I leave the WIFI open all the time...
I have the same issue. Wifi sleep policy changes by itself to "Never", draining the battery in just a couple of hours.

Turning off WiFi in sleep mode doesn't work
My 10.1 will not turn off WiFi when the tablet goes to sleep, per my selection to turn WiFi off wen the screen turns off. WiFi remains on when the tablet is in sleep mode--I can ping it successfully from another computer in my home network anytime. I want to disconnect whenever the screen turns off for a couple of reasons: 1) to cut down on WiFi traffic overall (I have a limited monthly data allowance) and 2) to keep some of the snoop sites from gathering information from my tablet.
3.2, rooted, kernel 2.6.36.4-cyanogenmod+ [email protected] #1 (overclocked)
Any suggestions?
Put it in airplane mode when you aren't using it. I have a button on the home screen to turn on airplane mode. Disables all radios, and really saves battery.
Airplane mode did it. The app I installed is Auto Airplane Mode. It simply puts it in airplane mode when I press the on/off button to turn the screen off (sleep) and takes it right out, usually by the time I swipe the screen, when I turn it on again. Works every time, no problems. This is much better than trying to debug the original problem, which sounds like it must be common to a lot of phones and tablets.
Thanks, Dave

Nice, I didn't know there was an app for that. Will save me a press when I sleep the tab!

[Q] App or mod for wifi sleep when screen is off

Can you recommend an app or a mod which control wifi connection when the screen is off? I notice that if I enable wifi, I got 20% battery drop per a day, but I got 2% drop if I disabled wifi. Still, I like to have wifi on when I am using it, and clicking several time to enable wifi is quite irritating (relatively). So I thought there might be a good resolution to handle this my lazy problem.
I searched it on android market, and can find several. Can you recommend any one which will work well with NookTouch? I appreciate your inputs.
Same problem pal. But I also can't fix wifi not reconnecting when nook is up from sleep state issue. Suggestions?
I use the power widget that comes with ADW. I can turn WiFi on and off from my home screen with one tap.
Is it possible for it to be done automatically? Like on my smartphone? When wifi is turned on and my nook goes to sleep mode then when it wakes up wifi is off, in "disconnected" state.
I use the program Llama. It lets you set up all sorts of conditional changes for phones (similar to Tasker).
On my nook, I have one event trigger. When wifi turns on, Llama delays for 5 minutes, then turns wifi off.
It isn't exactly the same as turning off wifi when the screen turns off, but it helps me save battery. I currently have it send a notification to let me know it is turning off wifi, so I have the option to keep wifi on if I so choose.
Edit: Llama does have an event trigger for Screen Off, but I couldn't get it to work. Maybe the Nook doesn't turn off the screen in the way standard android phones do, so the trigger doesn't run.
Edit 2: I just realized you wanted one that turns wifi off when turning the screen of, then reconnects when turning the screen on. If Llama correctly detects the screen off/on triggers, you could set up two events, one to turn wifi off and one to turn it back on. I haven't gotten it to work, so maybe Llama isn't going to work for your particular needs.

The NST is so heavily customized by B&N that you cannot rely on the "usual" events being triggered.
They only did what was necessary to save enough power and get the device to work and I don't blame them for that.
I'm pretty sure there's an event triggered that can be used for this particular task tho, if I get some spare time I might dig into it.
Well, I'm the impression, that my nook does that. I mean, when in sleeping mode - the WIFI is OFF. But when I awake the NOOK, wifi turns ON by it self and connect to internet. What I suspect, you might have the problem that other users experienced (including me) ... that you will have to change one file. Read more about it here.
I hope, this will help you.
Thx for all help !

WiFi randomly enabling itself

In the morning before I go to work I usually disable WiFi as I don't use it at work and would like to save a little battery. However, I've noticed that throughout the day, I'll check a notification and see that WiFi has turned on without me turning it on myself. I can't see any pattern or correlation that would match up with this. Does anyone know what would cause this? I factory reset last night (due to an unrelated issue) and it's still occurring. I only have a couple of extra apps installed, Falcon Pro and reddit sync.
i think power saving mode sometimes enables wifi when its available... not sure how often this happens or if thats even the issue you're having but check the power save mode settings... 3g and 4g use more power than wifi

I don't have the power saving settings enabled, and I don't see any setting that resembles that kind of behaviour.
So at some point while I was driving home from work WiFi enabled itself again (I didn't even touch the phone). I'm wondering if it may be S Beam causing it? I haven't actually used it but it's the only thing I can think of that would need to actually turn WiFi on. I may try turning it off tomorrow morning when I turn WiFi off and see if that stops WiFi from randomly enabling.
Galaxy S4 Wifi auto enable
Is there a resolution for this? I heard that on the S3 it would pay attention to what cell towers you are using and if it recognizes you are in an area where you have used wifi before it will enable and connect. This seems to be the symptom that I am seeing and it's bad for me. It keeps trying to connect to my work network because occationally I log on so I can access materials. but when I want to listen to Slacker Radio I can't because it's blocked. This is a cronic problem for my phone and I'm not able to find out how to disable it.
if you have got any battery saving apps delete them
