wifi battery killing apps questions (just wondering) - Nexus One General

i am just wondering so please dont post hate replies haha.
Apps:
Y5 (turns off/on wifi automatically when off/in range)
Sleepy Battery (turns off/on wifi when screen is off/on)
Task Killer Full/Advanced Task Killer Pro -(task closing apps when running in background and not in use)
the Y5 is meant to run wifi only in locations that are picked up and save to your device. the problem is that its constantly on even while its asleep/idle. does this actually kill your battery for being on constantly and monitoring the wifi's connection? having the app turn off wifi to save battery was a major battery saver for my blackberry so wondering if its the same with android nexus one.
the Sleepy Battery app disables wifi when the screen is turned off (sleep/idle) and enables wifi when screen is on. works well but does turning off the wifi off while the phones screen is off save battery vs having wifi on even when the screen is off? does turning off/on wifi on screen on/off waste more battery then having it on or off?
also, if using the 2 apps (Y5 and SleepyBattery) fight over enabling/disabling wifi make the phone drain due to constant active programs trying to execute the tasks?
hmm...
now moving on to task killing programs, does having them open on startup and keeping them on kill your battery while monitoring apps that are left on? the idea would be great to have apps automaticlly close when going to the home screen and forgetting to close apps that are not required to be open when not in use.
these apps sound like they should work great if they in fact down kill your battery! if the y5 does save battery while not using memory future updates with added option to turn off the wifi when screen is off included in the app would be an ultimate wifi app for power managing!
*i would like to note i currently dont have task killing apps installed although when i did they only was to close apps i know could be closed without them restarting like slacker radio, pixelpipe, and other apps that are used and can be closed and are not required to be running in the background.

+1 I really like this post because those are some programs that I'm going to pick up. I hope you get your questions answered because I wonder the same thing. Thanks for making this post.

Wifi Settings?

Hey guys,
been using my X10 for a while now (2 weeks) and the battery life is one thing that tilts me a lot... I tried all the tas killer, adv task killer, task panel lite etc, and none really worked
also, juice defender just somehow seems to screw up my wifi settings. I use no 3g/ data at all so i just keep that disabled.
However from reading this forum I downloaded an app called Spare Parts. It is really good in that it tells me what is using my battery in a detailed manner. so it tells me that my battery is being drained from
Running 12%
Wifi running 12%
wifi on 99.9%!!!
Now i made sure of all my wifi settings, I have it turned to "Sleep when screen turns off" in the android menu, and "android default" under spare parts.
I uninstalled juice defender bc i found that it was just screwing up my settings, it kept changing the "Sleep when screen turns off" to "Never" which resulted in more battery drain
I dont know why my wifi is running 99.9% but i gotta think that is killing my battery.. The really annoying thing is if I goto the battery use under normal android settings and it is telling me wifi only used up 6% of my battery since last charge?
sorry for the mega long first post but any help is really appreciated
bumppppp! Im sure this must be a problem for other people too who don't know their wifi is running 100%?
Not sure what advice i can offer you mate.
Although WIFI is definately a large drain on the battery i found the source of my battery problems were down to having the "Location source and & Data use settings" enabled.
Put simply it will try to use either your wifi or data connection to determine your current location. If this is left running in the background it will seriously affect your battery.
Its better to only enable them when required.
Hi - The answer is in your question...
Wifi running 12%
wifi on 99.9%!!!
This means that your wifi is switched on for 99.9% of the time which you phone has been on, but it has only been "active" or "not sleeping" for 12% of the time.. This is fine..
I removed Ulitmate juice a while ago, but reinstalled only the Juicedefender element last week and it's definitely making a difference to my battery life - especially when I'm out and about..
Have a good look through the power usage thread - there's loads of stuff the phone does in the background that you can switch off to save juice.
Yea definately know what you mean, the only thing thats bugging me is that i am 100% sure my wifi settings were... sleep when screen turns off... so for wifi to be on 99.9%??? Shouldnt that setting ensure the widi is not on when the screen is off?

What am I doing wrong here?

Ok I got the X10 a few days ago.. loving it.. now..
How do I extend the life of the battery? I know theres a ton of topics on this but I can't seem to get more than 12hours..
- I use StartupAuditor and pretty much stopped most apps from running at start.
- I use ADW Launcher
- I use JuiceDefender
- Timeout - Screen timeout after 15s, lock after 2mins
- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)
- Screen - Leave APN/Wifi enabled while screen unlocked (So it disables it after it has been locked)
Any help is appreciated.
After a couple of weeks your battery life should get better with out you having to do anything. Just be patient and let it fully discharge before recharging. Also restart your phone after a full charge and after using wifi and gps.

Discharing a battery is bad isnt it?
Well your problem may lay here
"- Schedule - Enable APN/Wifi for 1m every 15secs (for Moxie Sync/Mail - Push)"
Your using Moxier which other X10 users have identified as a huge power user and according to you, your also using APN/Wifi for a minute every 15 seconds..........so it's essentially never turning the APN/Wifi off :-S
Hope this helps!
Also fully discharging your battery every now and then is actually beneficial for your battery.
Quite certain the 1 minute every 15 seconds is a typo
Juicedefender defaults to 1 minute ever 15 minutes.
I removed ATK and Juicedefender, I found they only screwed up things in the phone and after removing them I noticed no change in battery life. (If anything, my battery life increased after removing ATK)
The best things for battery I have found to be.
-- Alternate launcher (I use ADW, I think Helix is better for battery performance but ADW has more options).
-- First 5 charges, discharge battery completely and do this again once every month or so
-- After full charge, power cycle phone (Turn off/on)
-- Use quick settings to turn off GPS, WiFi and Bluetooth when you are not using them
-- Make sure you back out of programs when you're done with them. This will close most applications so they are not running in the background. Certain apps (like a dolphin browser) have exit functions under more options. This is useful as back will just go to the previous page.
Note: Force closing applications which you see open in the background may use more battery as it may just start up again. Constantly killing and opening the program will use processor/battery power. Whereas many programs, when open in the background, are not using active process power and Android OS will pause/stop applications which are not in active use, by default.

Where can i find the timout setting for the lock?
Screen brightness turned down. Wifi instead of 3g. That's what I do. And I think I get around 15 hours. Still kinda bad. But better than nothing.

From my experience..
I find 3G has better battery life than WiFi, unless you are constantly browsing. When 3G is active, but you're not browsing the web and stuff, I find it doesn't use much battery. WiFi, however, uses up loads of battery when the phone is idle.

I want to know that as well Tried to find in phone settings but couldn't figure it out
Battery barely gets drained by wifi in idle state. you just go into wireless settings and set wifi sleep policy to when screen turns off.. should be fine after!!

As per my last question, discharging is bad isn't it? With these batteries, you have to constantly charge them so they don't loose life
Edit: Also.. if I press home button or back button that doesn't close the app.. most apps don't close like that, so I have to use ATK to kill it.. is it fine to leave apps running in the bg like that?
Edit: So I should uninstall ATK?
I also JUST got an X10 about 2 weeks ago! My battery life was so bad at first, and I ended up trying most of these battery saving apps. But to be honest, I found that they did more damage than good.
I now have everything I don't use turned off. Bluetooth, WiFi (when I'm not home at least) etc. Just skim through settings and turn off anything you don't think you'll use. And I restart my phone every morning and I get 30-50 hours out of it, depending on use. It is definitely getting better with time too.
For ATK, I would uninstall it as generally killing tasks does more harm than good. If you use it intermittently and only when necessary (and not use auto-killer) you could keep it installed.
As for apps running in the background..
-- If you press back, it should close most apps (not all, but well designed apps should)
--The Android OS is designed to pause/stop apps/processes which are not being actively used by the user and will close them eventually if left unused
-- ATK is generally only freeing RAM which is not important. It is not like Windows in the sense that more free RAM = faster speeds. It is a lot more like, more free ram = more wasted ram.
Here is a link to where I found out most of this information.
http:/geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
As for WiFi sleep policy, thanks for pointing this out. It seems that my phone is already set to sleep WiFi when the screen is turned off. I find this weird as I have found significantly reduced battery life when I turn WiFi on, even when my phone is mostly unused/idle.

Thank you so much Mobzter, but i was not after that As Sashi said that he has set "Timeout - Screen timeout after 15s, lock after 2mins", I know about about screen timeout but "Lock after 2 min", How? Thnak You anyway ^^
@mano. Good question. I can only find screen time out as well.

i have noticed some thing strange ,the phone lasts more with apps open in backgroung than when i close them . and using my phone consumes less battery than leaving it in standby .very strange phone (may be only mine ) any confirmation.
Hey Hoss,
I can confirm that force-closing/killing apps seems to be worse for battery life than leaving them alone. Backing out of apps usually will stop any cpu usage, but leave the app running. Killing/closing them will just result in more cpu power to run it when necessary.
As for standby vs usage - I have the opposite experience. The battery life on my x10 lasts a lot longer when I am working all day and not using my phone very much.

[Q] (Q) Why is my xperia play "awake" when the screen is turned off ?

Hey forum ! , I was an iphone 3gs user and made the jump to android when the play came out.
Ive noticed my battery is draining 2-3% an hour and looking at the "battery use in setting and then looking at the graph it show the phone is randomly awake even when the screen is off.
My play is rooted using gingerbreak 1.1 and has mostly all the bloatware removed.
non of the apps i have installed ask for permissions to prevent standby, I only have tune in radio, mobo player, facebook, twitter adobe pdf viewer, fpse, snesoid, gameboid google maps youtube imdb touch calendar es file explorer unit convertor and ringdroid installed.
i have 12 processes running using 86mb of ram
all apps are closed properly, wifi is off, background data is enabled ( but no applications i use in the settings allow auto refreshing of data)
The battery life of my xperia play has never been great (lasts about 24hrs with just checking facebook, twitter and xda forums using the built in browser)
I just wonder what is causing the phone to keep waking up randomly, is this the culprit of the battery drain?
I have a couple of theorys .... i did install desktop visualiser to change the icons then once they were changed i deleted the app (i read this app causes battery drain) maybe this could be a cause i thought deleting the app would fix,
2nd i travel around as part of my job so i wonder if the phone is going through areas where there is poor connectivity and its constantly trying to connect to different networks causing the drain.... but does anyone know of any efficient lightweight apps that disable this when the screen is off.
lastly I think the could it be widgets i only use the built in ones with the phone, the wifi on/off gps on/off and data on/off
do you guys turn data off during the day to save battery and do you turn background data off ? i think its anoying have to change all these settings off to sqeeze a tiny bit more of juice out the phone, it probably uses more turning them on and off avery 1hr or so
any suggestions or setups of how other people have got there phone up and running with good battery life would be a real help
cheers !
Deleting all widgets certainly saved my some battery, also deleting the SE launcher with launcher pro seemed to save me a lot of battery but I'm not sure about this.
2 to 3% an hour isn't bad with radios on at all. When you say awake, do you mean the screen is on, or that it's just in standby? There is nothing in battery stats that say "awake" you need to be more specific on what the system says, not what you think it's doing.
If the screen is coming on "randomly" then it could be an incoming txt, email, phonecall or something like that. Lower your screen timeout in the settings to help there.
If its phone idle or standby, then again 2 to 3% is nothing. That's 30 50 hours of standby receiving emails, txts and what not. Nothing to complain there.

Click on settings then about phone then battery use then at the top of that screen there should be a set of numbers saying how long the battery has been used since the last charge, click that an it displays a graph , on the graph page it shows when the phone is "awake" by awake I mean the screen is off the phone should be in standby mode but its being acessed by something i.e a program , like its woken up to perform some action. Anyway im wondering if anyone elses phone is awake randomly when the screen in off and in standby mode. When I factory reset I neget had this issue but its after installing apps I think or some setting im missing any ideas
I have the same problem. My Xperia Arc is "awake" all the time. Screen is locked, turned off but in battery usage I see that the phone is awake even with screen off. The culprit seems to be the native messaging app as it consumes the most battery. I'm not sure what is going on, what is the messaging app doing or which process is using it.
Any ideas anyone?

Help guys, about battery consumption

I have upgraded to GB firmware recently, and the battery consumption now is quite bad. So i use Juice Defender(free), it says the battery improved by 1.4X, but overnight consumption in standby mode could cost up to 40%, is there any ways to solve this?
Thanks
* I not sure should i post it here or QnA, please shift if necessary.

One suggestion is to stop using Juice Defender. I think it is keeping the the phone out of deep sleep, causing the overnight battery drain. Also, check if your wifi is set to turn off at screen off (Settings > Wifi > Wifi > [menu > advanced] > Wifi Sleep Policy). Turning off mobile data, or switching to 2g, will also help. Background data and syncing will also reduce battery life.
And yes, it should have been in Q&A.

I dont use data nor sync, i will only on the wifi if i need them, so i not sure why they drained so fast during the night since i off them, the day was ok(maybe due to JD).
Not sure is there any other alternative to help with this situation if i dont use JD?
Check your CPU usage using CPU spy overnight. Your phone should spend at least 90% in deep sleep. If not then something is keeping your phone awake burning up battery.

I just downloaded it from the market, all the bar have % in them, how do i just check overnight data?
You'll just have to leave your phone on through the night, then check CPU Spy again.

The original data wont affect anything? Because the data now are quite low on the deep sleep. only 30over %.
Before you go to bed, reboot phone and then leave it. Check CPU when you wake.

Just my 2 cents,
Juice Defender made my phone run extremely HOT
and the battery was draining significantly faster than usual.
Green Power Free is a good and free alternative, less features (only controls data & WiFi) but much easier to set-up too.
And it doesn't hurt battery life all that much.
Bear in mind though, any app that runs constantly in the background
and manages core phone functions, will impact your battery and CPU usage.
In my opinion, an APN and WiFi on/off widgets come quite handy.

I will try that and uninstall JD instead. =D
Actually i dont use data at all, so data ia off all the time. Wifi i used it at times, but i do off it when not in use. Sync i do not put it as auto too. I kill task quite often too.
EDIT: that app like dont do much, i didnt change change the setting at all, somewhat my basic settings. =X

DON'T.
See, most -if not all- task killers use a very "nasty" way to kill apps
and the system thinks that they crashed and immediately restarts them.
Which leads to increased CPU usage and battery drain.
Don't kill tasks, let Android handle its memory.
Does Android tell you what to eat and when?
Why should you tell it how to function?
If you have many useless apps that include background services,
(and I bet you have, since you are not using data and you installed Juice Defender! hehehe )
consider uninstalling them to "clean up" your phone.

Mostly i have is games and i do play them, i will uninstall them when i dont need them =X Some do pop out after crashing them, then i just force close them if they appear on the kill task list again.
Programs which appeared on the kill task list is what are actually running?

No, programs in the kill task list can be in either one of 5 states.
Read this:
Android
On Android, apps are suspended when they are no longer visible to the user. Suspended means the app is still in memory, but it is frozen. No processing or event handling happens. If the system needs additional memory, the least-frequently used apps that are suspended (in the background) have their state saved to persistent storage and are then killed, freeing up their memory. To the user though, those apps still appear to be in the background. When they are brought to the foreground to be used again, they are restarted and passed an object containing their last state so they can be restored to look exactly as the user left them.
If an app requires processing while in the background, then it must also have a service component. A service on Android is like a separate small application that runs without a user interface in the background (though not actually a separate application). The service has a server/client relationship with the app. It performs whatever action an app needs it to continue performing should the app be suspended. For example, the service might handle all uploading, so if an app is placed in the background while an upload is in progress, the upload continues. Or, like Pandora, the service might handle all network streaming and audio output with the app only acting as the front-end controls. Unlike apps, services are not suspended or killed (except in extreme low-memory conditions).

So, no need for task-killers, you are only making things worse. Trust me on that.

"Wifi off during sleep" but frequently turns on/off even during sleep?

Noticed in battery settings that my Wifi turns on and off frequently even when my device is sleeping. Doesn't seem to be affecting battery life but I'm wondering why it does this. It happens on both my Nexus 7 (stock rooted) and my Nook HD+ (CM11). I do have the "always scan for networks" settings off.
Attached screenshot is after I didn't really use my Nexus 7 for about a week.
I would imagine this is caused by certain apps requesting data. For example, your Gmail app may be set to refresh every one hour, which means it needs to use the WiFi to search for new data and download it, if needed. Other apps are similar to that as well, depending on your settings.
If it really miffs you, you can always use tasker and create a task that shuts the wifi (I have it put it in airplane mode since it does several things in one shot) off when the display goes off and back on when display comes back on...will need to be rooted.
