Go to: Settings > Wireless & networks > Wi-Fi settings. Hit your Menu button and select Advanced. You should now see an option for changing the Wi-Fi sleep policy.

As far as I'm aware, Android basically just doesn't work this way. You can turn off the screen ("sleep" mode) and put it into airplane mode for some extra battery saving, but there's no "standby" equivalent like on a laptop. The processor should underclock itself when you do this, too (how much probably depends on the device). And, as Lie Ryan points out in ...

On a pretty much vanilla build on my EVO, I can get to it by going into Settings->Wifi->(Menu Button)->Advanced. It's listed as "Keep WiFi on during sleep". Just be sure to tap on the left half of the "Wifi" menu item, since the right half is simply the toggle.

There an app developed to deal with that issue, Smart Timeout Keep Screen On by guidology available from Google Play Store: Smart Timeout allows you to specify apps that will keep the screen / display on. Once there are no specified apps visible on the screen the normal screen timeout is enabled. Works great while reading articles in web browsers, ...

There is a free app called MotionUnlock, with it your tablet will sense when it is being picked up from a table, etc... and unlock automatically, being ready for use! MotionUnlock - Tablet Wake Up

Though I don't know about any "official way" (did I miss some option in the playstore app?), I can think of a work-around using Tasker (or a similar automation app). As a long-term Tasker user, I can best describe it for this app, which is the most feature-filled and complete automation solution for Android (but for sure not the cheapest and easiest one). ...

Go to SETTINGS > WIRELESS > WIFI SETTINGS. Press MENU > ADVANCED. Ensure the WiFi Sleep Policy is set to NEVER. This will make sure that your WiFi remains always connected. This may however result in a marginal increase in battery consumption.

While the logcat option recommended by Ryan of course is a valid possibility, it is not the most user-friendly solution. I've got a better idea :) Apps started automatically after boot registered for a certain event, called BOOT_COMPLETED. To do so, they need to request this permission (you find it under "more" on the playstore pages) called "Start after ...

The screen doesn't randomly turn off: it turns off after a fixed time. You can change how long before the screen turns off in the main device settings: Display → Sleep. This applies regardless of what app is in the foreground. If you like, you can use a third-party automation tool such as Tasker or Llama to change the screen timeout according to what app ...

This function is also referred to as the "keyguard." Most of the phones that I have had do not allow you to toggle this on and off in the settings. Clearly something, possibly another app, toggled this off. I use Tasker to manipulate this setting. You may need to be rooted to do this but you can enable or disable they keyguard manually or programatically. ...

This is a power consumption thing. Most time when you're not using a smartphone it's in suspended state. I.e, as many as possible components are off and don't consume power. Awake means the CPU is in the running state. This usually means you're using it and the screen is also on. Android devices also regularly wake up to check email, push notifications and ...

In my view, battery capacity i.e. the mAh value is best the way to compare. The reason why I say this is that the battery drain includes so many factors that even a small software glitch can show a remarkable difference. Hence the standby time is a combination of several factors which are not reliable for comparison, unless they are from from same ...

What version of Android are you running? In CyanogenMod and other versions look in SETTINGS > DEVELOPER OPTIONS > STAY AWAKE / KEEP SCREEN ON WHILE CHARGING You might also want to take a look at this app, if the options aren't available to you. Seems like this question has been answered earlier - How do I keep my Android 4.0.3 phone awake when USB ...

It's none of the two. Turning of the screen of an Android device will not hibernate it (thinking of a phone: What about incoming calls if the device would be hibernated?). Android handles things a little different. In the best case, with the screen switched off Android enters a very energy-saving mode called "deep sleep". It will cycle down the CPU to a ...

Clearing the data on apps is a good way to "fix" misbehaving apps. I've noticed sometimes apps go haywire and stop working properly. Sometimes rebooting fixes it. From my time in the modding community loading custom ROMS (CyanogenMod) there was a time when Google Talk on some of the ROMS wasn't working correctly. I don't know what fixed it. At that time, ...

You can use an app called ClockSync, which fetches time from NTP servers and updates the device's date and time. Rooted users can make this app to update time at configurable interval.

You should be able to use either Locale or Tasker to setup a condition (i.e., at 2 am) to do something (turn volume down, stop media player, or turn off wifi or other services). But as far as I know, neither program will let you shut down your phone.

Suggestion: Use Tasker to disable screen timeout for your app. This may prevent it from going to the background.

To the first part of your question; how can I get more information about what apps are killed when & why? The Android SDK has a quick summation on the Android Memory http://developer.android.com/guide/topics/fundamentals.html By default, every application runs in its own Linux process. Android starts the process when any of the application's ...

I am pretty sure that isnt an option in the default design of android. I have never personally seen an app for such things because most people desire the programs to shut down to keep the speed of the phone up. It is the android system that is shutting unused programs down. The creator of the app would have to design a service to keep it running in the ...

I believe it depends upon the music player app. Have you tried using another music player? In my case, I didn't encounter this issue. I have used Samsung Galaxy 3 with several music players including stock player and also with a Bluetooth headset. I think the app itself is the cause for this, which is causing screen wake-up on next/previous, and in my ...

Right, the best you can do is download this app called 'aSpotCat' from the Google play store. This will iterate through your listing of apps installed on your device. To carry out the task - Tap on 'aSpotCat' that is the app that was downloaded from the Google Play store. Tap on 'List apps by permission' Tap on 'System tools', this will expand, and ...

I have solved the problem by flashing modem (aka baseband aka radio) only through CWM / recovery mode. This way i have kept all my settings and apk's and rom and kernel. The files i have used (for SGS i9000) can be found here: http://forum.xda-developers.com/showthread.php?t=1158783 You have to choose appropriate modem according to your ...

Yes, using Airplane Mode will reduce power drain, as the commentors have already answered. But this approach can't be considered Call Standby, because you will not receive calls. From the point of view of cellular operator, your phone behaves exactly as if shut down. Switching to Airplane mode shuts down the cellular connection, including voice and data, ...

If you are connected to wifi, then it may be set to turn off when the screen is turned off. You can use the video linked below to explain how to do it, in essense: Go to the System Settings Select WiFi Press the menu key Select advanced Change Wi-Fi sleep policy to 'Always' Video

I hope you use ClockWorkMod , reflash the custom rom after clearing the cache ,factory reset,etc,. If the problem exist try flashing other roms and see if the problems is due to the Custom Rom. If you are having the problem only when using the first custom rom, then contact the developer of the Custom Rom and ask tell him about your problem.

It's odd that it happens. My last few devices always stayed on while Navigating, when Navigation was a stand alone app and now that it is part of Google Maps. You could go to Settings > Display and turn the screen timout off. Double check the settings in Navigation. Alternatively Screen timout toggle is an application on the Play Store that seems to be ...

I use tasker for that: Context: App (select all apps to apply this to) Task: Keyguard off, display timeout to infinity (optionally add more, e.g. brightness settings) Almost nothing that cannot be cured with Tasker :)

If what you want is to keep the screen on while a certain app is running in foreground, there are several apps around which can help you out. I personally use tasker for this (ever since I bought the app years ago) successfully with a recipe that rawly reads: Condition: App (select the apps concerned) Task: Display timeout (set higher, or disable it ...
