Android :: After 30sec Phone Goes Sleep
Jan 1, 2010
My problem is or has just started for some reason it was working fine yesterday. When i use my phone and then leave it alone 30 secs it goes into sleep mode and the lock is applied, now before i used to be able to push the menu or home button and the lock screen is displayed to which i can then swipe it down to unlock. This has stopped working all of a sudden, i press home or menu button and the lock screen will not swipe down to unlock the only way i can get into the phone is by pushing menu twice. I liked using the swipe down to unlock it. Is there any reason this has started to happen all of a sudden?

I previously had a blackberry curve and loved the sleep function where phone would shutoff every night ay 10 and turn itself on at 6:00, is there an app/function for the droid where I can do the same?

Why does the youmail app not let my phone sleep? Background: Installed youmail app, realized battery was going FAST. Looked at awake time and it was 100%. Uninstalled all apps since the awake time debacle. awake time returns to normal. Re-install only youmaill app, awake time goes back to 100%. Go into preferences or settings, whatever and set for NO polling at all unless requested, no notifications, nothing. Awake time still 100%.Un-install youmail, awake time back to normal.I really like the app and the widget, someone tell me there is a way to fix this. I would like to re-install and use this app.

I'm developping a LiveWallpaper on Android 2.1. This application must download an image every fifteen minutes and draw it on the screen. Everything works except when the phone is in sleep mode. Do you think it is possible to run an application like this when the phone is in sleep mode? And if yes how?

I've written a test service to understand how android implements a service. I believe I understand the difference between Context.startService and Context.bindService. If I am not mistaken, Context.startService will tell android to keep this service running, even after the Activity that started it has ended.
While testing the service, I have come across something interesting.
My problem is that the service appears to sleep or pause for a few hours, run a short time, and then sleep for a few more hours, then run a short time, etc when the phone has become inactive. In other words, when I am doing things on the phone the service is doing what is is supposed to. But after I have finished doing things on the phone and the screen goes blank the service appears to sleep or pause. I don't know if I have implemented the service wrong or if this is how Android services work.
The test service I have written simply sets a postDelayed handler to increment++ a variable in the Runnable every minute, and then write the value of that variable and a timestamp to a file (log.txt) on the sd card. This how I know that the service appears to sleep. Because there are gaps in the timestamp that correspond to when the phone was inactive. If the service were truly active the whole time, there should be a line item in the log.txt file every minute.
From the log.txt file below you can see that over an eleven hour period there are only 36 line items with time stamps ranging from 10:27 PM through 9:23 AM. If the service was running and active the whole time there should be over 600 lines in the text file. The phone was on AC power the whole time so Android should not have tried to stop services due to power issues. The phone was not used or touched from about midnight to 9 the next morning, so there should not have been a low resource clean up.
I have spent several days looking for an answer and everything I can find seems to validate that when a service is started and not bound, it will stay running (http://code.google.com/android/reference/android/ app/Service.html). However, it appears it does not. Unless I have completely missed the ball on this.
I have included the service.java and activity.java as well as the log file.
Here is a sample log.txt
CODE:...............
Here is the service java file:

I'm trying to check if the phone is currently asleep in a service. It's currently a very messy implementation (I'm reading a file in the filesystem that says if the phone is asleep or awake every 10 seconds) so I'm wondering if this is possible with PowerManager or something.

I'm using a combination of alarm (set with AlarmManager) and background service to periodically synchronize data in my application. The only problem I have is that when sleep policy terminates Wi-Fi connection the synchronization no longer works. Is there a way to "wake up" the Wi-Fi connection that has been put to sleep? GMail somehow manages to do that because it notifies me about new e-mail even if the phone entered sleep mode.

Is there an app that can turn off my wifi whenever I put my phone to sleep? To conserve battery, I always have to turn off my wifi before I turn it off, and turn it back on when I unlock it. After a few days of this, it gets pretty annoying. I'm used to the iPod touch where when you sleep it, the wifi automatically turns off to save battery,and when you unlock it, and turns it back on. It would really save me the time.
Also I noticed this Wifi sleep policy thing. I don't really understand, can someone elaborate or explain more. Is it that when your not using your wifi for +15 min, it automatically turns off? Do you turn it on manually, or does it do it auto when you starting using wifi programs like browser.

I have a service which polls a server at certain intervals. I use an AlarmManager and a BroadcastReceiver to start the service. My problem is that after a certain duration, even though the WiFi is still enabled, but for some reason, my application can't contact the server. I get an "Unreachable network" error. Note that I've already acquired a partial wake lock as well as a wifilock. Here's my code for the BroadcastReceiver.
public class ServiceAlarmBroadcastReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
WakeLock wakeLock = null; WifiLock wifiLock = null;
try { PowerManager pm = (PowerManager) context .getSystemService(Context.POWER_SERVICE);
// acquire a WakeLock to keep the CPU running
wakeLock = pm.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "MyWakeLock");
if(!wakeLock.isHeld()){ wakeLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WakeLock acquired!");
WifiManager wm = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiLock = wm.createWifiLock(WifiManager.WIFI_MODE_FULL , "MyWifiLock");
if(!wifiLock.isHeld()){ wifiLock.acquire();
} Log.i("ServiceAlarmBroadcastReceiver", "WifiLock acquired!");
context.startService(new Intent(context, ThePollerService.class));
} finally { // release the WakeLock to allow CPU to sleep
if (wakeLock != null) { if (wakeLock.isHeld()) {
wakeLock.release(); Log.i("ServiceAlarmBroadcastReceiver", "WakeLock released!");
} } // release the WifiLock if (wifiLock != null) { if (wifiLock.isHeld()) { wifiLock.release();
Log.i("ServiceAlarmBroadcastReceiver", "WiFi Lock released!"); } } } } }

I was investigating the issue of setting up a delayed activity/event, that will occur and trigger even if the phone is in sleep mode (wake up, do what you need to do, go back to sleep). I was thinking of the following methods: 1. sendMessageDelayed 2. Timer 3. AlarmManager.The basic requirement is to be able to set a triger in the future, and be sure that this trigger wakes up the system if it is sleeping,perform the task, and go back to sleep.A partial wakup is required (no screen flickering). Currently i'm using the sendMessageDelayed, and i keep a wake lock held for the timeout period (bad practice).

cell standby 23%
wifi 26% ( just realized it somehow got turned on through the day)
phone idle 24%
android system 12%
voice calls 9%

I can't think of anything else to mention, but PLEASE someone give me some advice as to what is making my phone stay awake!

Ok well I just realised that my phone is dying rather quickly now and come to find out, my phone is not going to sleep for some reason. Never had this problem after 2.2 update and all the sudden it happens. Last thing I downloaded from market wad pdanet. Any ideas to what could be going on?

I apologize if these topics were already covered in previous threads.I wasn't able to find anything related in my searches. Auto-rotation for keyboard when answering a text message received in sleep mode does not work. If I actively send a text when phone is already awake, keyboard rotates with no problem but when I go to reply to a text that I received while phone is in sleep mode, the keyboard does not rotate. Is this the norm?I am also experiencing a delay when the I wake the phone. After unlocking the phone, I used to go straight to my home page, now I get a "loading" message which takes several seconds. Is this due to the number of apps I have loaded? Is it possibly due to number of photo frames I have on my home screen or the complexity of the wallpaper?

After weeks of being afraid, i finally installed the new update to my evo last night. My phone isnt/wasnt rooted before the install...and my battery life seems to really crappy since i did the install last night. I took the phone off the charger at 7am, used it just for texting basically, sent maybe 50 texts back and fourth and now the phones at 68% battery life via system monitor.
I check the about phone and it says the uptime and awake time are the same...is this because it was changed with the new software? the phone was on and plugged in all night and its only giving me an "UP" time and awake time of 3 hours and xx minutes?
Anyone else have this problem? with the phone being awake, will this kill my battery faster? i searched and could only find problems with the eris, not the evo, any ideas?
I had this problem the first week i got the phone, i had terrible battery life and sprint reset it, and made the problem disappear...i had awesome battery life averaging 10-18 hours on a single charge with heavy useage...any ideas?

So after applying the update my awake and uptime are identical. I'm trying to see whats the easiest way to find the source of it? Im guessing its an app that I was using on 2.1 that isnt working right with 2.2.

Today I noticed some very rapid battery drain and narrowed it down to Palmary Weather. I figured out that you must use the back key until the app exits for this to work correctly. If you just press the home key while in the app, it will keep the phone awake.
OK, I was just giving a quick heads up, but might as well keep a running list to make this easy. Just please make sure you've actually proven these apps have caused this issue or else we might have 1,000 listed. Also, this is not saying that the app is causing you an issue, just the obvious ones to look at when you do have a problem.
Known Problem Apps
- Flickr (if Facebook for HTC Sense is also setup to sync)
- Palmary Weather (updated:issue only occurs if you do not exit the app correctly...working fine now)
- Profile
- Slacker Radio (some do not have an issue if you hit Menu/Exit to close app...others still have issue)
- Google Listen (must be configured to only download while on Wi-Fi and while charging)
- Meebo
- Alice
- MyLock

I could not find it with search. I'm back to having less than 5 hours of battery before it shuts down. At 3:00 today I was at 100% charge and at 6:00 I was at 40%. The really interesting part is when I look at the battery details. I'm at 30% right now and I have 3:24:15 of uptime and 3:23:56 of awake time. Something is not letting the droid sleep. Other than stock apps I have, xtremelabs speed test, connect bot, keepass, astro file manage and K-9. The only app that should be running is K-9 and it's using 4% of the battery.

Over the last week or so I've been obsessed with trying to get my hero into sleep mode, in order to save battery. For those who don't know about this, there are many threads around the net telling of a fix for the messages bug, which prevents the phone entering sleep. It's supposed to reduce CPU usage, thus saving battery.
Now, I've followed the methods of many people who claim to have done this successfully, down to a tee, but for the life of me, I can't get it to work. For some reason my awake time is always at 100%. It's now at the pont of driving me mad, and I'm just wondering if anyone else has tried and failed to do the fix. If anyone needs background info on this problem, I'll post a link up later, as I'm sending this via my phone at the minute.

I'm definitely diggin' Swype on my Evo, however I've got a question that hopefully has a simple answer. My phone used to go to sleep after a minute, which is what I like/want. Since I installed the Swype Beta today, it won't. I have to go and tap my power button to make it sleep. Is there a work around for this?

I am not rooted and I don't have 2.2. Have wifi, bluetooth, etc off. I have spare parts. I was losing 20-30% battery overnight with my phone fully charged at 100% so went into spare parts in battery history and it said the phone was running 100% for 12 hours. So to test it today I plugged it in, charged it to 100%, unplugged it, killed all tasks (even task manager), shut the screen off and sat it down for 2 hours. When I turned it on it was at 80% and spare parts said runnning 100 and when I click that it says "time spent without sleeping 2hrs (99.99025592487624%)

For some odd reason my phone will not "sleep". The screen just stays on. The only way I can get it to sleep and the screen to lock is to push the power buton on top of the phone. I have the screen set to time out at 1 minute. I have searched and read but no real answers for this phone.

This just started happening. The Dinc won't auto lock itself nor will it go into screen lock when I press the hold/power button. I set the screen lock time to 15 seconds and after 15 seconds the screen only dims but doesn't lock.
When I press the power button to awake the Dinc it pops up to home screen or which ever screen I slept it at. i tried uninstalling the apps I updated and downloaded but no luck
ETA:
Installed ATK just to see what apps were running. Everything looked normal. I took of the reminder I had in my calendar and the phone is locking itself after screen timeout has expired and power key works. I put my reminder back onto my event and it is still locking.
Conclusion:
Dinc has a mind of its own and was probably amped up on Starbucks since I had some today for the first time since owning the Dinc
