Sep 14, 2010

I've heard everyone mention that setting wifi to never sleep has helped battery life but I can't figure out where to find the controls for that policy.

Samsung Captivate :: WiFi Sleep Policy - Battery Drain?

Aug 2, 2010

What is your take on the WiFi sleep policy. I do like the fact that Wi-Fi can remain on all the time, but will it be a drain on my battery? Is it better to keep the Wi-Fi to sleep on screen shut off? I am near a Wi-Fi connection for most of the day and always at home.

Samsung Captivate : WiFi Connection Turns Off When In Sleep Mode By Default

Jul 22, 2010

I am new to smartphones and thought that this might be good for others who are new and don't have the unlimited data plan grandfathered in to know.

This was posted in reply to another question I had had about Pandora so the credit goes to poster MeVirtually.

By default the wi-fi setting is set to go to sleep (and use cellular data instead) when the screen is off, which will most likely happen while you are streaming music as well as other things. To change it so the wi-fi never turns off, to into the phone's menu -> wireless and network -> wi-fi settings -> tap the menu button and select advanced which has an option for wi-fi sleep policy that had been defaulted to sleep "when screen turns off". There you have the option to change it to "never" or "never when plugged in".

Samsung Captivate :: WiFi - Sleep Policy Causing Wake Lock For Android System Process And Draining Battery

Dec 1, 2010

After noticing my battery was draining quickly, and then after reading this thread, I installed Android System Info to see what was draining my battery so fast. I notice that whenever I would turn on WiFi, the phone will never go to sleep , regardless of what I set the WiFi sleep policy to. After turning off WiFi, the battery still drains heavily.

The WiFi will shut off after 15mins (if you set it to "When screen turns off" or "never when plugged in"). However it seems to keep the CPU on causing it to drain down the battery.

It would seem that whenever WiFi is enabled, the Android system process creates a partial wakelock that does not go away even if you turn off WiFi. The only way to resolve this is by powering off or rebooting the phone.

You can verify this in Android System Info by going into Battery-History-Other Usage-Partial Wake usage to see how much time the "Android System" process holding a partial wake.

I even did a factory reset on the device; and it is still happening so it doesn't appear to be any app that caused the issue. As I said, it works fine as long as I don't enable WiFi.

I already know of two users having this issue, but I'm wondering if folks having battery problems are going through this as well. Is anyone else having similar issues after using WiFi? I'm hoping someone will be able to identify what exactly is putting the wakelock on and we'll be able to find a fix for it. Other than not using WiFi at all or rebooting the phone after using Wifi.

Samsung Captivate :: Disable 3G From Going Into Sleep Mode

Sep 9, 2010

I've noticed when the phone goes into standby mode (press the right power button), the 3G eventually turns off. Is there a way to prevent that from happening? I'm assuming I can't get any notifications (i.e. Instant Messenger clients, Google Voice, etc.) while the 3G is off, but not sure. I'm also assuming 3G goes into sleep mode, as when I power the phone up I don't see the 3G icon (is that assumption correct?).

Samsung Captivate :: What Would Be Draining Battery When I Sleep?

Aug 9, 2010

I went to bed at 1am and woke up at 10:20am. My battery was at 65% before bed and 44% when I woke up.

I killed all tasks with advanced task killer as I do throughout the day as well. I don't use the email program on my phone nor do I get any notifications for any other programs. My Wi-Fi sleep policy is set to never because I have Wi-Fi at home. Brightness is at a low setting too. So, any ideas what would be draining my battery during the overnight when I'm not using my phone? I don't have problems during the day when I use it.

Samsung Captivate :: Screen Turn On When Press Power Button From Sleep?

Sep 6, 2010

Anyone else having a problem of not having the screen turn on when you press the power button from sleep? It doesn't happen often but it does happen. This is my second Captivate as my last one would shut itself off randomly and that phone also had this problem.Yes, I make sure I pressed the power button and waited a couple seconds to make sure it just wasn't lag but I can guarantee you it is not. Like I said, it doesn't happen all the time but maybe once every 2 days. I'm guessing it's a slight problem with other users as it happened on my last phone but I'm not sure. Hopefully it's a software issue.

Samsung Captivate :: 3G Not Lit Up / Need Wifi?

Sep 5, 2010

I was wondering if the 3G is not lit up and I don't have E the box or WI-fi, what the heck am I connected to? Seems that the 3G has a mind of its own, south FL. But if it's not on nothing else comes on either. Is this right? Now that I have my GPS fixed this goes out.

Samsung Captivate : 3G Still Being Used While I'm On WIFI / Way To Fix

Aug 3, 2010

When I first got my Captivate and turned on WIFI the WIFI symbol would pop up and take the place of the 3G symbol at the top but lately I've noticed that when I turn on the WIFI both symbols remain at the top.

I have the unlimited data plan so using up data is not a problem for me. I'm just worried about battery life. Is my phone using both at the same time? Is that even possible? How do I go about fixing this?

Samsung Captivate :: Cannot Connect To Wifi Or 3G

Nov 29, 2010

No connectivity at all on my Captivate. Wifi networks can't be saved, and the 3G symbol is up there, but there's nothing being transmitted or received. Should I do a factory reset? The phone part works, as does messaging, but nothing else.

Samsung Captivate :: WiFi Not Working / Way To Fix?

Jul 18, 2010

I swear that WiFi seems to quit working half the time. I'll be browsing the web, it will quit working, and I can turn WiFi off and 3G works just fine. When I re enable Wifi, it works for a bit and then does it again. I'm on a 24MB/s Internet connection, and everything else wireless in the home works fine(my iPhone 4 works flawlessly).

Samsung Captivate :: No 3G After Being On Wifi Overnight

Jul 29, 2010

I seem to be the only one having this particular issue with the Captivate. With a new sim card i have 3G, take it home and put it on wifi overnight, and the next day i cannot get 3G. have done reboot, soft reset, master reset, toggle flight mode off/on. The only thing that gets 3G back is another sim card. I have gone through 2 phones and 4 sim cards with this. Samsung support is scratching their heads, any ideas from the android community?

Samsung Captivate :: Wifi Keeps Turning On Itself

Sep 8, 2010

I have a new Samsung Captivate, and I can't keep the wifi off. No matter how many times I go to settings (or use the pull-down curtain), and switch off the wifi, within a minute or so, the wifi comes on again. It also turns itself off again periodically when this happens. I don't have any after market power manager installed. I suspect this may be down to an app, but have no idea where to start looking for the solution.

Samsung Captivate :: WiFi Not Turning Off

Jul 29, 2010

Something new - under Wifi Settings / Advanced - I have Wi-Fi set to sleep when display is off. This doesn't seem to be the case. My WiFi is Always on. I would imagine that the icon would disappear like it does when WiFi is turned off, but when the phone is asleep and then wakes up, the WiFi connection is still there. Anything I can try to fix this? I have tried changing the WiFi sleep policy to the other 2, then changing it back to display power - didn't work. I did have to reboot the phone last night because I couldn't get WiFi to turn off, but I don't have a problem today with turning it on or off, just won't go to "sleep"

Samsung Captivate :: Wifi Not Turning Off 3g?

Aug 12, 2010

Last night my wife was trying to update her cached stations on slacker radio and although connected to wifi slacker gave a notification that the data would be downloaded over 3g and an unlimited plan was recomended. The strange thing is I had full strength connection to wifi but the 3g icon was still there and and the red and green arrows were showing data transfer over 3g. When connected to wifi on my captivate the 3g icon disappears. A simple power down fixed the problem and wifi was present and no 3g icon in the status bar.

Samsung Captivate :: WiFi Keep On While Asleep / Fix It?

Aug 19, 2010

It's become a standard recommendation on battery-related threads: Set WiFi to stay on when the phone goes into sleep mode.

My understanding is that 3G is only active when data is being transferred. But when WiFi is on and connected, it is ALWAYS on and connected.

Let's say I sleep for 8 hours at night, and I have apps that update every 30 minutes. Do I want WiFi to be connected for the entire 8 hours, or just let the phone use 3G for a total of 16 times (8 hours / 30 minutes)?

For some reason, my WIFI is no longer auto-connecting to networks. I have to go into WIFI settings and manually connect to a network. This happens if, for example, I'm on WIFI at work and then come home, it does not auto-connect to my wireless network without manually connecting it.
