[Q] What's best? Wifi Off when screen is off or Wifi on all of the time? - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

To start off with; i get good battery life; right now I'm at 1 day 3 hours and I have 39% left.
I was wondering however, does setting the Wifi to go off when the screen is off help significantly on the battery? And if so...is there some other negative issue that I'm not aware of if I set it this way?

I'm pretty sure any sort of data connection will use more of your battery than WiFi will. So if you're always around a strong WiFi connection you probably should leave it on at all times.

Oh that is funny.
I just do everything everyone else does:
1.) Screen off when not in use
2.) Screen brightness down as much as possible.
3.) Dark theme.
4.) Tasker profiles to turn off wifi when not near my house or work.
5.) Tasker profile to turn off GPS when not actively using certain apps.
6.) Tasker profile to turn off BT when not connected.
I also am probably a light user...the only thing that I do beyond normal phone use is to watch Netflix a slight bit a day and stream Spotify a bit.
I also don't play games except Words with friends.
No FB no locations, no nothing like that.

Wifi off and data off would be most helping when screen off

Battery Life

I have a widget that shows me how much I have left and when I unplug it after a full charge, I have 6 hours left.
Ridiculous.
This is on auto brightness, wifi, twitter/facebook/mail updating every 15 minutes.
whenever I take my phone out the house I have to bring a charger...
bloody ridiculous.
couple of points.
1) When you leave the house, don't leave your wi-fi on! I find wi-fi to be the biggest battery drain out of everything ( expect gps)
2) I use a brightness widget, therefore when your in doors you can have it on low, then when your out doors have it on high, i assume this will use less battery then auto brightness
3) why do you need facebook updating every 15 minutes?? Do you honestly look at your phone that much when your out? change the settings so it updates every 15 when your on wi-fi at home, and every hour for when your not.
Wifi isn't an issue. I leave it on 24/7 as well as bluetooth and still can get 36 hours out od a charge. Its hooked up to wifi 20hrs a day as well.

1. Battery and other constantly updating widgets are one of the causes for battery drain. Get rid of it.
2. Battery widgets try to get an estimate of your typical use. They are mostly wrong in my opinion
3. I can get 6 hours of battery, yes, but only if glue the phone to my hand and use it constantly for that time
4. there are tons of battery threads around, use those suggestions (mid brightness, no live wallpaper, turn airplane on when you know coverage will be unavailable for long, etc)
5. Battery gets better in 10 days.
6. Most people can get at the very least one day of heavy usage. If you really need to hammer the battery get a spare one, they are cheap. Oh, and realize you are lucky because you CAN have a spare battery !
7. If you are using an automatic task killer, get rid of it.

1) go to the market and search brightness level, or brightness widget, there are a number of these. The best i find is brightness level by curvefish, it lets you pick a percentage and keep at that .
2) Cant remeber actually where the settings are but there is a way. But i prefer to use another widget, autosync on/off, this allows you to update every 15 when on wi-fi, but when you want to save battery, turn auto sync off and it doesnt sync ,
I suggest you use switchpro widget. its like the power control widget but with more options to turn on/off things.
I typically charged my Nokia N97 every other day or so, even though I used it frequently, and needless to say the HTC Desire doesn't have the same stamina. I was quite frustrated by it, and I started thinking of ways to save power. I came up with 19 tips, and I have actually noticed quite a difference by following them
19 Tips to Keep the HTC Desire Running a Little Longer
Nice post thanks.ill give this a go. But I have a question to do with the positioning using data or gps. I believe your stating that you should turn data off for this purpose, and let the gps do it? however my phone was set to opposite. when I changed as you were suggesting and I clicked allow gps, I had a message come up saying to turn off to conserve battery? But your saying to turn on? And have data off? Also how do you get into htc facebook settings,i cant even find it!

yep i also use this widget
also use a free juice defender or paid ultimate juice that keeps turning on and off your 3g every now and then depending on how you schedule it, my phone with snowstorm weather widget updating every 80 minutes + 30s of 3g every 5 minutes to update mail etc and average usage lasts about 36 hours which is good enough for me
I leave my WI-FI on at home and suffer hardly any drain.
At work like today leave my Mobile network on down to 47% with just twitter usage!
Pathetic is the mobile signals drain.

Ok, ive had another read of this and am now just even more confused! Are you saying to have gps turned off via settings and location aswell as data, or just having gps on? Are you saying that having gps selected via settings for the purpose of locating services uses les batty than via using data? Either way, it appeatss that the power control widget controls the gps the same as via settings. Right now ive deselected gps and the data location.

I believe this is what I'm saying:
"To let your device learn your location via wireless network triangulation requires less battery than by using the GPS for this purpose. However, using both methods simultaneously is probably not a good idea from a battery point of view. The GPS can handle this task by itself, although it will get a fix on your location a little bit slower. Also, wireless network positioning will be used to collect anonymous Google location data, which will drain the battery further. You can change this option from Settings > Location > Use wireless networks. "
In other words, to only use wireless network positioning will supposedly use less battery than by only using the GPS, but using both methods will naturally use the most juice
For me...
- Turn GPS On when I needed.
- Turn WiFi On when I needed
- Turn Bluetooth On when I needed
- Use 2G Network for standard internet, we use 3G if we want more speed such us watch video

I can get get good days heavy usage (except games) from mine, I haven't tried the 2G thing yet.
Apparently it is the connectivity thing that kills the battery, but turning off 3G, doesn't that take all the fun out of it???
If you just use it as a phone then I reckon you can get a couple of days out of it, or so I've read...

Tasker - Profiles

Hey everyone
Does anyone here use tasker or have any recommended profiles to help save battery life?
Sent from my GT-I9100 using XDA Premium App
Try Juice Defender with 3g control enabled.
I have mine set to enable every 30mins with good results..
With LOTS of syncing enabled, i get roughly 1% an hour decrease whilst on standby!! Unplugged at 1am on 89% when i went to bed, at 9am when i got up it was at 81%...
Hope this helps!
Dickie
Check WIKI on Tasker site,data profiles created by "brandall" from XDA
Tasker data profiles are better than Juice Defender
JuiceDefender has some annoying bugs in it at the moment (some like issues it has with lockscreen/display timeout) have been around for 4months+ and they still haven't sorted them out) so I've switched to Green Power which seems to do the job very well. Simple and no fuss.
Hi. Anyone here good at creating profiles?
I would like some help. If i want a profile that:
IF screen has been locked for 1 minute, i want WiFi to shut down.
And when i unlock the phone again, i want it to turn on.
But - i don't just want a "toggle wifi by hitting powerbutton"-function,
I only want this to apply if i had wifi on in the first place.
The reason i want this profile is:
If i forget to charge the phone at night, and have wifi going, i have 20% less battery when i wake up. Or if im at a friends house, connected to a wifi... well, same here. If it just lays in my pocket connected to X, i want it to shut down when screen is off. Saves alot of juice.

Why don't just use the stock android checkbox in settings that's there for that? o_ô
Go to settings/network and wifi/wifi settings/hit the menu button and tap advanced parameters/wifi sleep politic/check "when screen goes off".
It does exactly what you described...

The reason i don't use androids built-in thing for that is because it drains battery for some strange reason.

Well mine is working fine, no draining at all (wifi on 24h24 with this option checked and my phone drain only 1% every 5 or 6h if the screen is off). The thing is that it shut off the wifi only if no app needs it, so my bet is that those who have a battery drain just have some apps that don't let the phone going in deep sleep.

Hi, if you try LLAMA app instead I could talk you through it (as your not getting an answer you want).
As far as I can tell, LLAMA can do everything that tasker and locale can do but its free. It's also very good on your battery and can use cell towers instead of gps for location.

Not sure if I'm in the right place, new to smartphones. Got myself a Galaxy S2 and rooted it. Main point,
I'm using Tasker and I'm trying to have it set so that it's in Airplane Mode when I have an Alarm set so I get no calls/texts during my slumber.
So far, best thing I've done is the phone goes to Airplane Mode between 00:00 and 0600 everyday as well as when light levels are between 0 and 28 - not sure if the light levels are like, set too low.
So far I love Tasker but very little support online and Tasker Wiki doesn't really help. Trying my best with the trial and error method.
Thanks

Poor Battery Life

I am getting very poor battery life. Fully charged at 8am and dead by 5:30. Hardly even using it. I have a limited number of apps on, just a subset of those on my Nexus One and no rouge ones at all. Made a few calls, no web, a couple of gtalk posts and that is it.
See attached usage screen charge to dead and charging again!
The phone is useless like this... any ideas????
Are you in a building with poor reception? I noticed this issue when I left data on when my company moved buildings.

Is that solid blue bar from your WiFi being on all the time, or is that your awake bar on 100% of the time from a bad app?
That battery life looks atrocious. Show us the second screen to see the "awake" times.

That's it, like I say a sub-set of those on my N1 and all solid apps.
I normally listen to mp3 on the N1, but have not had time on the Galaxy yet, so it;s getting less use.

Other than that, don't see anything crazy... This battery life is really strange. When your screen is using less power than the 'Android OS' it shows you're really not using the phone much, but the phone is still tanking on battery life.
I'll post those screen shots for today when I get home tonight.
A few things I have noticed though. It seems to level off at midday, this is when i leave work and go home for an hour. While at home I will be on wifi. I do not connect to wifi at work.
Secondly, while at work I notice my data often changes between "3G" and "H", while the phone is in the same place. Probably 60% H and 40% "3G". It is not practical to turn "2G" only on, as I get the volume bug and the phone becomes unusable.
I am wondering if the data signal is draining it somehow? If so, how can I work around that? Like I said, I have a N1 before the GN which sat in the same place on my desk every day and had no battery drain issue at all.
I unplugged mine yesterday at 7.30am and it died at 9pm
I used the internet on/of all day made a couple of calls and about 50 texts, screen on time was about 4 hours.
Today i've used it in a similar manner and as of now (3pm uk) 7 and a half hours in its on 57%
The battery in this thing is better than my desire, granted, not much in it but it will easily get a normal user from one sleep to another

I'd say with 95% certainty it's just signal-hunting causing the drain. With my Fascinate at work, I'll easily lose 50% battery within a couple of hours, even if I'm not using it, while at home it'll last me between 15-20 hours before getting low. Easiest solution is to just buy another charger for work, and leave your phone plugged in whenever it's on your desk.
Don't like seeing android os at the top of that list! Does the nexus share some of the problems that have plagued the galaxy s line of phones, the android os bug!? :O

I kind of think you might be right. However, a phone that drains itself while doing absolutely nothing useful at all, is no use to me. I carry it about and am in and out the office though out the day. It would be unworkable to keep putting it on charge every time I come back in the room. I need a phone I can carry around for a working day without charging. My old N1 did. If this can't do it I'll need to get short of it and get something more practical. Seems ridiculous though.
Btw, task killer just got installed by default when I upgraded. All the apps that were on the N1 were installed when I signed in. Just never deleted it
Do you leave your Wifi on all the time even if you don't have Wifi signal available? Don't do that.
If you are too lazy to manage your data connection manually all the time, I highly suggest getting the app Juice Defender from the market. You can save the battery by setting a schedule for data connection and also it will disable your wifi automatically if your phone can't find a wifi spot it can connect to.

Yes, I leave wifi and bt on. I want to be able to do this. I am not asking for it to run for days. 1 full day is all, I have not issue charging every night.
I could look at the juice monitor, however, it does not seem too much to ask to be able to get 1 full day from it of average use. To me, it seems perfectly reasonable to expect the device to work for a full day with all services running.
Is there any tool than can be used to prove that the signal hunting is eating the power? Currently is seem to be in the big pot called "Android OS"??
Well, I'm not gonna defend the phone. Leaving all radio processes on, especially when there is no signal available, is well known to drain a lot of battery since the phone uses more power to search for available networks than when it has a stable connection to one. If you leave it on in a place with spotty or no signal it will make the problem worse.
Juice Defender (the basic one anyway) is free and pretty much manages the connections for you and basically extends your battery life with minimal effort. Give it a go for a couple if days.

I strongly agree with chrono.

+1 with Chrono.... Turn off Wifi completely if you are not using it.
if you are a new android user, you should also check the settings of the phone:
hit *#*#4636#*#* in the dialpad.
this will bring up a menu. there you should try phone (i think, my n1 got stolen a while ago). there, you scroll down and there is a menu to adjust the preferred network mode.
if it's set to CDMA preferred, it will search for a cdma single. you just adjust it (i think) to gsm only. google will help you a bit here.

This is illegal, if you cant buy an app dont use it.
It's a paid app
WORTH EVERY PENNY
I have automated mine to do the following
As soon as I enter my work car park, it drops the volumes, switches off WIFI
I leave my work car park, volume to max,
I enter home, WIFI on, Volume max
after 11pm - 6.30am everything on silent, wifi & data off
then when i scan my NFC tag in the car, switches on GPS, loads co pilot
re-scan tag, turns off GPS and closes co-pilot

Was thinking the same. Any partial/wakelock issues caused by the program constantly assessing the environment. As it happens I am thinking of using the program to reduce battery drain and shutting down WiFi when out of range of home networks but if it's negated by the situation above it seems pointless for my needs.
Any one care to comment?
I've been using Tasker for a couple of years accross 4 different devices now (X10i, DHD, TF101 and GS3). I have a lot of profiles set up to do various different things and I can honestly say I've never seen a noticeable effect on battery life.
That said though I don't use the GPS location state at all. I imagine that particular state would drain battery pretty quickly. I use the WiFi Near state a lot though and, as I've said, never really noticed a detrimental drain on the battery.
I suppose it depends on what you do with it but overall IMO it's a very well written app. Extremely useful too.

Waiting for app sale. The price is slightly higher than what I'm prepared to spend, especially because there is a free alternative from Microsoft called on{X}: http://techcrunch.com/2012/06/05/onx/

Yep! This is what I was hoping to use it for too. My betterbatterystats has identified my Wifi as the one real drain on what is still a very good battery life. So although I could turn it off myself I just know I will forget to turn it back on at home and would like a program to do it for me. BUT if one negates the other it's not worth the effort.

Well your WiFi has to be on to use the WiFi Near state. You could potentially combine it with a Time state too though. Just for example you could have Tasker turn WiFi on for 1 minute once an hour to check for your network(s) then either turn off again if no network detected or connect and remain on if a network is detected... if that makes any sense!
It would save battery compared to leaving WiFi on all the time.

What effect does it have on, I have a task to turn of Wi-Fi during 10am and 1pm; but I try to turn on Wi-Fi during this period. Will it automatically turn it off again, or allow me to continue to use Wi-Fi?

It will allow you to continue to use it. That sort of profile works as a toggle based on the time state so at 10am it will turn it off - but only at 10am. If you were to turn it on again straight away it would stay on until you either turn it off manually or another profile kicks in which is set to turn it off again. The same goes for anything else such as ringer/silent/vibrate, mobile data, GPS etc.
@Greedyfly: you're welcome

You guys can try Llama...does the same thing and cost nothing....i am using it for couple of days and it is good.

Tasker can do wonders...but it requires you to be some kind of Tasker-scientist to get things done. I recently discovered Llama as well. It's free and simple but capable.
Yeah Tasker does have a reasonably steep learning curve admittedly. By no means insurmountable to most though.
I suppose it depends on what/how you want to automate. Tasker is very powerful but not so simple. Llama is free and easier to use but no so powerful.
Both are good automation solutions. Locale is another one to check out.

I've been using Tasker for the best part of a year now, awesome piece of software. Negligible impact on battery life and it's astoundingly powerful. A few examples of profiles I currently use - detects headphones/bluetooth headset and reads any text and who sent it, useful when cycling or out on the bike. Disables screen lock when at home, I use the phone as a control for my media centre so it remains unlocked at home and turns the screen on as soon as the handset is picked up, controls a variety of connection states according to location and time.
These are just scratching the surface. On top of this I've had direct dealings with the dev on a couple of occasions, genuinely nice bloke who does his damndest to solve problems as quickly as possible. All in all, this and Titanium backup are by far the two most useful pieces of software I've bought:good:

But Tasker is better, even if its complicated
Thats the reason i gave a link to a noob friendly guide

I love tasker even if it drains my battery(but it doesn't)

Battery life

I am suprised, there still is no battery life thread.
People must be very happy with their battery lifes or nobody is buying this tablet
I do have one big issue with battery life.
WIFI is the biggest battery hog, using 2-3 times more battery than the screen.
For 3 hours WIFI roughly 1400mAh.
So I only manage like 5 hours of SOT.
Btw. I have set WIFI to be disabled, when the screen is off.
Any suggestions?
I haven't had mine off charge long enough to really be able to comment about this yet but I can't complain with it so far.
Mine seems good so far. Had one freeze as you can see. 33% left.

Still, I think it is strange (as seen in your screen shots), that WIFI accounts for almost half of your battery usage. And 5+ hours SOT is only 6%?
Could you be so kind and post the screen for wifi too, so we can see the "computed power use"?
When looking at my phone, wifi is at 52 mAh power use over an 18 hour period, on this tablet it is 2700 mAh for 10 hours.
An alarming discrepancy.
Or am I missing something?

Here you go. I'm guessing screen is only 6% because the tablet has been up now for 4 days, so 6 hours is a small portion of the activity.

Doesnt Wifi use more battery when its connecting and reconnecting with it disabled when the screen is off?

I really don't know. You may be right.
I guess the high wifi in battery stats is a reporting error / miscalculation. I have wiped the cache partition in recovery (to fix my ambient light sensor) and ever since wifi is at the bottom of my battery list.
And I did not get any better SOT, so there could not have been any real battery drain from wifi even when it held the top spot in the stats.
Still disappointed with only 4-5h SOT.
Thanks everybody for helping out.

No its still going to use far less unless your picking it up every 30 seconds or so.

my understanding of how android has utilized the wifi sleep policy is that its best to leave wifi always on when sleep. It will use more battery to reconnect to the wifi network when it is woken up and disconnect when sleeping.
Any sources to support your theory? I'd like to read up on it more.
Info I've always followed. This is from 2011 as well:
"This tip is one that seems counter-intuitive, but you can save a lot of wear and tear on your Android phone's battery if you tell it to keep the Wifi radio turned on and connected while the phone is sleeping. Your phone needs a lot of juice to keep pinging those cell towers, and even more to transmit data to and from them. Wifi radios use much less power because of their design, and they don't have to keep searching for a better access point. It's the way cellular data communication was designed, and it's a necessary evil.
But what if you're spending all day (or all evening) in one place, connected to Wifi? If you tell your phone to shut off Wifi when idle, it bounces back to cellular data (be it 2G, 3G, or 4G) and starts sucking down the electrons again when the screen shuts off. That's no good, and easy to fix:
Open the advanced Wifi settings by pressing the menu button, then Settings, Wireless & networks, Wi-Fi settings, and tapping the menu button again. You'll have a choice to either Scan, or go Advanced -- go Advanced.
Tap the Wi-Fi sleep policy entry, and you'll get a pop up dialog with the choices you see in the picture above. Choose Never.
Now even when your phone goes into standby mode, you'll stay connected to Wifi and be able to get mail and messages without turning the cell radio back on and trouncing your battery life. And for the times when you're not in an area with a Wifi connection, just shut Wifi off, either through the menu or with a handy toggle widget. Your battery will thank you for it."

I know that leaving WiFi on runs your battery down on any device when its connected and it takes all of 2-3 seconds to connect. No reason to leave it on full time when your not using it. Also, the device is continuously checking and sending small amounts of data to maintain that connection.
Were talking about the pixel here and not a cellular device.
Pretty happy with the C.
I haven't really payed attention to how long this device lasts, I use it pretty casually so it lasts me up to a week. I have used it to stream movies and it has lasted me the whole day (8 hours) watching movies with about 30% left. Compared to other tablets I've had including the nexus 9 this one blows them all away. My old nexus 9 would die after a few episodes (about an hour)

I streamed a good 6 hours of a live feed on battery and the device used around 50%, can not complain with the battery life at all with this device

No, just WiFi, don't have a keyboard.
As a heads up, there appears to be a WiFi issue with MM itself. I'm seeing the same issue on my Nexus 7 2013 running a MM ROM, and I found a thread online talking about it...maybe from the Android Central forums or something, I can't remember now. People seem to be unsure as to whether or not WiFi is actually causing a battery drain, or if it's just reporting incorrectly. But at least on my N7, the battery can drop 40-50% in one day while on standby, and when I have WiFi set to Off when it's sleeping. And I used to get DAYS of standby time before going to MM.
Edit: Here's an XDA thread about it: http://forum.xda-developers.com/google-nexus-5/general/guys-call-wifi-battery-drain-6-0-t3219870
I had the same issue with WiFi battery bug on the nexus 5. Fixed it via router by turning off the auto disconnect (the option where router decides if a device can connect based on signal strength) on both 2ghz and 5ghz. After this the Wifi went back down to the bottom of the battery list. Long shot, and most likely not even related, but hope it helps anyone.
On a Asus rt router.
