Turn off wifi or not - Galaxy S I9000 General

i want to know... is it better to turn off wifi when screen turns off or 3g consumes more battery than wifi.
i think 3g consumes more battery than wifi, i don't know why every one recommend to turn off wifi when screen turns off.
Additionally, the process of switching on/off wifi/3g will consume more battery...

Turn all data connections OFF when not using them.... this will save battery.
you can use wifi sleep policy, but if you are on GB you may experience Android OS drain...

turn off all data and set wifi sleep policy to never

WIFI OFF when not using - most of its idle state consumes up to 10x juice as data connection at idle (15-50 mA / 5 min)
DATA CONNECTION can be ON <- at conected but idle state it is not using more juice then if that would be off (5 mA / 5 min)
as well as BT and GPS can be ON all the time

ofc itt will not be so low if youll have sync every minute or some live widgets

Get juice defender, set it up right, and you will see a big gain!

there is no need for any juice or battery defenders
any task/proces killers/managers or any paid or free apps
that are said to make your battery life better longer better whatever
basicly stay away for wifi and remember when you play games, use gps or simply use the phone battery will go down.

How did you gather this data?
I want to do some testing

battery monitor widget gives you such data and many cfg options
that is data given by diff phone codes gathered in one place, presented in configurable graphs and more...
damn i sound like commercial =)
this 5mA in idle is due 5 background apps (all sort of monitors i run)
think with a clean system it could be 1-2mA -that means-> basicly no % loss when you are sleeping and phone is not used
now i have few % loss by night but i find that more then ok

In my opinion you have definetly turn off ur wifi if not in use. It'll drain your battery!

nice thanks^^

3G use more battery then WIFI does

jvp - idle - no

i leave always wifi off do not make sense to keep it on since it will be scanning the hole time for new network (which mean more battery wasted) .
Also when i leave my wifi on sometime the phone connect to some near network , which require some http identification , so the phone will be connected to wifi network but without internet , in this case email sync and other auto update stuff will not work until i get away .
SO here when needed and there is a wifi network available i just switch it on .

iget searching->connecting->disconect
on my MIUI galaxy, there is a fix for that?

Battery life and idle data connection

Did anyone try to compare battery life between no data connection and idle data connection?
I always turn data connection off after update, but I am asking how does idle data connection effects battery?
I know it drains it...but how much?
And the reason I don't know results from myself...
Sometimes my battery drops from 100 to 90 or less over the night, sometimes from 100 to 80 or even more, with the same usage or any usage at all...so I don't know how to compare it because it's so random...and this is without data connections, it is only device with phone on in sleep mode...
I once compared an over night-drain where no connection took 3% of the battery and with data connection 4%. Approx 8h sleep
It's hard for me to compare during normal use since my usage varies a lot from day to day. So I have nothing to contribute during daytime usage.

I was using wmlonglife for some time, however one time it stops to work - i have found that i had a permament data connection in idle, but didn't notice a thing, so technically it do not drains the phone dramatically
when you guys say "idle" data connection, is the phone not automatically checking for email accounts etc? If not have you disabled them overnight - how do you do that please?
From yesterday until today, until now, I left idle data connection and it dropped in 12h from 80 to 75.
When I tried to close connection and left it overnight it dropped from 100 to 93.
By my expirience there is difference in battery drain: 15% with idle data connectino and 7% without data connection.
But numbers change from day to day...but more or less is 2x more when i have data connection on idle
might have to do with the network.. most networks do their work at night because they seem to asume everybody is asleep.. it could be offline every now and then but keeps searching for updates..
Mine has 3g toggle turned off, but the 'data connection' toggle is always on, i have three email accounts that get checked over edge every 2 hours, and battery drops roughly 2% during 7 hours sleep.
yuo have 3g off permanently or just overnight?
What do you "lose" when using 2g vs 3g?
My options about 3g mode is set to auto, so I guess it switch to 3g or hsdpa when available...

yea 3g permanently off. I live right on the edge of my local 3g coverage, and with it on itchews through the battery as it switches on/off/on/off. I get full reception using edge which is easily fast enough for surfing low bandwidth sites(like xda dev! ) twitter and emails etc.
my HD2 drains battery VERY fast when i have idle connections. when i don't turn them off my phone battery is from 100% to empty in about 6 hours.. but maybe there is a problem with my device / rom.
i hate to use your thread for topic for this but maybe anyone can help me with my battery being empty so fast? i am using Dutch stock rom v1.66 with standard radio rom. i am going to try a newer radio rom tonight. but i dont think that is going to help mutch.. i dont mind flashing to a custom rom but i want the same user interface as i now have. i dont like the custom one's with their shiny buttons and stuff..
would really apreciate help / advise!

Thanks. I think the most bandwidth site I would currently access is Facebook.
I will try 2G then. When I get more into using the phone as an internet device I guess I could turn it on.
Mind you in the middle of a major city and moving from Voda "excellent" to "very good" signal zones it should stay 3G most of the time not switch so often......
the rom i.m using makes it easy to manage data, left soft button on home screen brings up comm manager and all the toggles have been activated, takes moments to switch on/off 3g and wifi, the rest of the time the edge data just works fine.
incidentally, in terms of power use other things to look at that might get overlooked, block size on sd card, if its real small and you have lots of sd card access, such as progs installed there, browser cache there, can significantly increase the number of read writes to the card in any given time period, costing power.

Battery drain while idle - "suspend" process

Hello,
When I got my SGS it only ate 2-3% of the battery during the night. Since then I've tried many different firmwares, currently on the latest JM6, and all of them have had a very annoying problem. It eats 8-10% of the battery during night. I haven't changed anything, wifi is "always on" to avoid it eating battery using 3G. Ofcourse I've tried turning it off, too. The funny thing is that using Spare Parts it seems like it's the "suspend" process using a lot of CPU, which I believe it definately shouldn't. Some times after flashing it seems okay and can sleep properly, but then it goes haywire again - without having installed anything since it worked. Anyone else having "suspend" process using a lot of CPU?
To test, install Spare Parts. Plug in the charger, and remove it again to reset stats (Spare Parts uses some system app to show the CPU usage, and its default view is "since last unplugged", very practical). Go to bed. Sleep. Wake up. Start Spare Parts. Select "Battery History". Click "Other usage", select "CPU usage". Wait for half a minute or so (it needs to load data, if you click anything now you won't get CPU time used). Find the "suspend" process. Check how much CPU it has used.
I might add, that this doesn't seem to have anything to do with wake locks, it's something strange in the system itself.
try next time with all unecessary items off
like WiFi, GPS, BT anything that you don't use when you go to sleep

I use JM5, Wifi Always on, 3G Always on, Auto sync off when unnecessary.
I was working at the polling booths on Election day here in AU, that's from 7:30AM till 11:30PM, I didn't really need to use my phone for anything, but when I got out 16 hours later I noticed that I had only lost about 3-4% battery.
It's pretty good. D:
For the record:
Bluetooth - This only needs to be turned off if there are devices that auto-pair with the phone, such as a bluetooth headset, in which case you probably want it on anyway?
GPS - This does not need to be turned off as it only uses battery when a service is actively requesting a gps fix. For example if you have Maps open it will drain more battery, but it won't on standby unless you are using Location tracking software or otherwise location aware software.
WiFi - Truth to be told, WiFi when connected uses less power than a 3G connection on standby. WiFi does have the potential to use a lot more power than 3G because of the higher speed potential over a local wireless network. In most cases it's pretty safe to have WiFi always on, however it should be noted that when WiFi is NOT connected it will constantly scan for access points to connect to, this process uses power ON TOP of 3G, so it would be wasteful to leave this on unnecessarily unless you were using it for Google Location services via WiFi access points.
3G Data - The only reason this 'uses power' is because it's a always-on connection, you can partially remedy this by giving WiFi always-on priority saving both mobile data quota and some power. 2G uses a lot less power than 3G simply because it uses the GSM chip in the phone, not it's own higher power chip. So switch to 2G if u don't need high speed data, but want always on Push notifications and such. (EDGE is fairly fast, but I only get GPRS and 3G on my carrier. )
Brightness - This phone has a super bright screen, use something in the lower settings, auto brightness at day if you want.

I've got bluetooth off all the time, it's currently running a very new install of JM6, and I haven't installed anything that runs when I don't want it to run. 3G isn't used, as wifi is always on (advanced wifi settings).
It's around 7 hours since I pulled the plug, after having restarted phone after removing SD card, and the suspend process isn't even on the list anymore... I find this quite interesting - it might just be a coincidence, but right now it looks like there is some kind of problem with suspend process when SD card is in... Do you have an "external" SD card in your phone?
ive just flashed JM1 and hate how much power its using... no idea what the problem is, but ive just come off the official JM1 from Kies, and had a big problem so had to flash the first thing i could find. can this really be down to firmware?
i mean im really noticing a difference on standby, before id loose like 3-4% in a whole day of not using it, now it drops 10% in like a few hours...

i do use 16GB class 6 external SD from Transcent
MoWa22,
I had this happen to me last night and (am stock DXJG04) so very interesting. Trying to remember what my battery drain was last night but I think it was around 10-15% and previously I would get 1% if I turned everything off except being able to receive calls.
I always thought these issues were related to wake locks or that the phone just cannot sleep. Something to try is to reboot the phone and check the battery power before going to sleep and see the battery drain over the night. If minimal battery drain, then maybe it is a rogue app which you may have opened/used during the day. If same 8-10% drain, then am guessing some service or inbuilt process is causing issues.
Half the battle is trying to track the CPU hog or rogue app.
Dang. Lost almost 10% again tonight - but actually the "suspend" process almost didn't use any CPU, SD card still not in phone. Using the built-in battery usage thing, it has cell standby on top, phone idle right below. This is really starting to bother me...
Last night while I turned off APN, Wifi, GPS, etc, I left my phone on as 3G only. I've heard the switch between 3G to 2G causes extra battery drain so I had left the phone on as 3G only. I know 2G is lot less of a battery strain but wonder if it affects cell phone standby. Going to leave my phone on 2G tonight.
I have 3G and sync on. I have weather and feed widgets updated every hour. Plus some other widgets and Google Latitude which I know is using cpu time. My drain is about 1 to 1.2% drain per hour of standby. Firmware DJG4.
I think you dont need to bother too much if battery drains 1-2% per hour on standby (this gives you at least 2-4 days if you use the phone very little). Any more than this means you may have some rouge apps/widgets.
The more critical is the usage time (i.e. with screen on). This is usually like 15-20% drop per hour of use.
Been testing a bit again - this night I had a total of approx. 1% battery used in 9 hours. Still without SD card. I inserted the SD card one hour ago, and I've lost 5-6% already - and suspend process is on top of the list again... Definately something weird going on when SD card is inserted! Please, can anyone test with/without SD card and check for differences?
I spotted this thread and read with interest as last night I noticed my power dropped "unreasonably". I've not started any troubleshooting yet but I am curious about the SD card thing.
Have you tried having the SD card in, but unmounted? Does it still suck powere when unmounted?
Obviously unmounting it is a simpler and quicker process than removing the cover and then physically removing the card.
Mark.
Upgraded to the new Froyo today, seems to be without suspend problems even with SD card. Gotta check how much battery it'll eat during the night.

How did you manage that? Everything off? auto-sync off? Wifi? 3g? 2g?
I'm on jm5 with Samset 1.9f and for all the time ive had this phone it has only used 2% battery overnight. Exceptional cases were when i used Fancy Widget, it ate up all my battery overnight leaving me with nothing for the next day. Have stopped using it ever since.
Nowadays, my battery drains heavily when screen is on(when im using the phone). Drains roughly about 1% for every 2 mins im using it, but standby time is still great at 2% overnight...

The new Froyo beta JPC. Same settings as always - WiFi always on (which by the way seems to be default setting on JPC). Everything else standard (it won't switch to 3G while using WiFi).

Better Battery Life with WiFi On

For some reason no matter what build, radio or rom I use BatteryMinder tells me that I will get better life with wifi on vs wifi being off. (check jpegs in attachment)
If i turn mobile data off too I get better battery life as well.
Why is the Mobile network killing my battery?
I would guess this has something to do with 3G that gets disabled on WIFI start
Yea I figured that how do I fix it though?
I stop using batteryminder because the time fluctuation was killing me! one minute it would show 1 day of battery left after unplugin, and 5 minutes later would show 15 hrs left, but only 2% had dropped in the battery, I guess it reads everything that's running, and takes it into consideration to tell you what time you have left. I get like 3 to 5mA at idle so I don't need it anymore to tell me how much battery I have left, I get a full day of battery.

This is a known fact, the wifi radio uses alot less power transmitting data than the 3G radio. I have about 20 Wifi access points stored in my phone so that it connects to them automatically like Home, work, church, parents house, friends house, that way the only time I'm actually using cell data is when I'm in the car. Saves the battery a ton.
If you want to use 3G all the time, but save battery, turn off always on data in the settings and set it to sync on an interval instead.

Odd, when I enable WiFi and set it to never sleep (so it keeps WiFi on when screen off instead of reverting to data), I idle at 10 times higher mA than with WiFi off. When actively using the connection (browsing, etc) it does seem less energy consuming than data, though.

Same here. Idle goes up to 70mA with no sleep.
I set it to "never when plugged in" and it seems to work fine.

This is all excellent advice. Cheers roloracer! I use similar settings and software for the most part with Core Droid HD v.02 by Sergio76 right now, and the standby drain with WiFi and GPS on, auto background data sync off, sits much of the time at 7 mAh. This is without using SetCPU. Moreover, with WiFi and GPS off, the standby drain drops down to about 5 mAh on average. This is about the same as I get using EVO Black & Blue Remix v.03A with everything off as well. That said, both of the above mentioned builds are incredible, IMHO, and both include the hastarin r8.5.1 Kernel.
Best to all,
R
If you are in an area with spotty coverage, and constantly switch between 2g, 3g, H, etc... then it supposedly runs your batt down a lot more than in steady coverage.

How much mAh do you have when you use your phone and how much
When It's in standby??
I got 3-6 mAh in Standby and 110-400 when using the phone (500mah when using the camera)
With this info my phone only last around 10-13 hrs

10 to 13 hours of heavy usage is not bad, light use is a different story, even on windows mobile with heavy usage you can see about the same 10 to 13 hrs of battery, My phone averages about the same as you, at idle with the screen off is about 3 to 7mA , with the screen on but nothing extra running about 120mA, and with stuff in the background about 250mA, or with the camera is about 400 to 500mA. The key is to always check advanced task killer, kill all before turning off the screen, I use my phone lightly to medium during my work hours, I text a few times, facebook a few times, some phone calls, but during all this time I keep my background sync data off, I only turn it on if I have to go into the market, and I turn it back off after I finish in the market, then when I get off work, like 13 hrs after I unplugged from charger, I usually still have about 50% to 60% battery, I flip on the background data and go full blast on it, til the end of the day.

i have to say, the juice defender rocks, totally solve my battery problem.

actually, i still dont understand how it works. days before, i keep.complaining the bad battery, it drops 15% after one night. i turned my wifi and 3g off, it didnt work. i opened a thread to complain about this, some friend advise me to use the juice defender which really help a lot. now it use only 3 to 4% for 8 hours standby, which is much much better than before. if u are also troubled by ur battery, give it a shot. it's free from the market.
my set: all enable except for the location.

What does it shut off? Seems like it has to be something important to work. I want my email in real-time; does it mess with that?
I installed this only a few hours ago. yet to see any significant change. By the looks of it, having it on the default setting will turn data off when your screen is off, but I still get e-mail notifications in my 1hr check intervals even when my phone is sleeping.

The main feature is that it disables data most of the time (2g, 3G or wifi) and only enables it at preset intervals, like 2 minutes every 30 minutes to get your e-mails and stuff.
So basically what you lose is push / real time notifications.
It can also manage the screen brightness and CPU clock more precisely, put the phone in plane mode while you're sleeping (for example you can tell Juice defender to go in plane mode from 23:30 to 6:30 every day, except if you're still using your phone after 23:30 or start using it before 6:30), or activate wifi only when you're in a specific location.
Does anybody have issues receiving MMS picture messages with JD or any other power saving app running?
I had 'Green Power' running yesterday. A few people sent me pics which came through as blank. Stopped the app and asked them to resend and it worked.
Thanks

I tried this app too, but the battery draining when WiFi was enabled was higher than without JuiceDefender. Still trying to get through all the JD settings...
I dont think Juice Defender would work well for me as I use Whats App a lot...
I use it on my ego. One of the best apps i bought
from my phone duh
Is anyone else able to toggle the 2G/3G setting? I've paid for the Ultimate Pack (wish i hadn't now as the Plus pack is supposed to do this) but apparently JD doesn't like my ROM, the Log says: 'ROM is not compatible with AOSP helper (3G control is unavailable) - get CyanogenMod
Out of interest i was on a UK O2 branded phone so i flashed XEU KW7, then rooted, then put back the original KE7 kernel. I wonder if that's the problem?
I was messing with Juice defender, but I found the app called Battery Booster to be much, much more effective. I went from a 12 hour battery, to having between 24 and 28 hours the last 3 charges. Simply amazing, more than doubled my battery life. Using perhaps 1-2% per hour when sleeping.
1-2% per hour when sleeping is not that good, i get 3% in 8 hours when sleeping.
But juice defender does what should be built into the gingerbread and that is, it puts your wifi and 3g to sleep when your screen is off or when you are not using it.
I personaly dont use push notifications so loosing that doesnt bother me, what bothers me is when the phone is in sleep it drains because i have wifi on.
I dont want to be turning wifi on and off all the time, i want it to be automatic, when i go on the web or open an app that uses data it should turn on my wifi.
SO YES JUICE DEFENDER DOES ROCK.
Well, before battery booster it used 5 - 8% per hour sleeping, so I'm pretty darn happy with the results I'm getting now. It used to last me about 12 hours. Now it lasts usually over 24 hours, which is great. That is included with 3-4 hours of screen-on time. Android OS also dropped by 20% after getting battery booster.

You do know there's a setting for turning of WiFi when screen is off, right?
Settings - WiFi - Advanced - Wifi Sleep Policy

actually, i still dont understand how it works. days before, i keep.complaining the bad battery, it drops 15% after one night. i turned my wifi and 3g off, it didnt work. i opened a thread to complain about this, some friend advise me to use the juice defender which really help a lot. now it use only 3 to 4% for 8 hours standby, which is much much better than before. if u are also troubled by ur battery, give it a shot. it's free from the market.
my set: all enable except for the location.

Unlikely but a factory reset often cures a problem .

no problem at all with push services.
the way juice def works is simple: it geolocalizes ur wifi router, and moving out the area of wifi, jd switches off wifi hardware until u come back home\office. it does the same with other hardware modules not in use.
wot doesnt work: ebuddy or other istant massaging apps while screen is off (I think it's unuseful to use jd with IM-draining batt-apps)

Hmm, am I doing something wrong leaving my phone charging overnight? Will that kill my battery?
When do you guys charge the phone if not overnight?

24 hours in a day so i charge when it needs a charge 20% left or when i know i want extended use .

I just installed Battery Booster. Juice Defender didn't do much for me but annoy me.
Now see how this app will hold itself.
Very similar to my finding with ATK (link below). Something happened in Gingerbread with how the OS handles cached apps... to the point where some cached apps stay active and keep your device awake!

Best way to increase battery life...

This isn't a thread for when your battery drain is excessive on standby, this is a thread dedicated to figuring out how to simply get more power to the phone for extended runtime.
I'm using a 5000 mah external battery pack for extra charge, and it seems to be good enough to last me at least an extra day or two of usage, which is great. It seems like the only other options are cutting up the battery door to fit an extended battery from the evo 3D or just carrying extra batteries...
Best easy change for me was always using wifi instead of the network when at home and work. Made a huge improvement

So....how to get the most time out of your battery in standby?
As you've allready said:
One of the biggest improvements is possible by using a Sensation or Evo3D battery. With that i get a nice 1% per hour in standby. (It's actually a bit lower than 1%).
While not using the phone it's unnessecary to have 3G activated. Recieving emails and texts via whatsapp, viber etc via 2G is good enough. For everything that is more datahungry you can allways activate 3G manually.
Keep background data turned off. I use K9 Mail which works independently and Whatsapp recieves messages too. But a lot of other stuff doesn't syncronize which means less wakelocks and thus less power consumption.
Same with locations. As long as you don't WANT to tell google your every step you can keep network based location turned off.
If you need a location fix quickly you can allways turn on gps for a moment. After using the FasterFix app (i guess you need root for that), i get a gps lock in 5 seconds, so i can determin my location really fast and share it with others (for intance via whatsapp) without having to keep it on all the time.
And last but not least:
You probably don't need to know the current outside temperature every 5 minutes. So set that to manual update too.
Doing these things doesn't turn my smartphone into an overweight dumbphone with a battery problem and i get a maximum of over 4 days of standby time out of it.
Normally my battery holds for roughly 35 hours (1 day and 11 hours), but it's usually awake for 1/4th of the time serving as my newspaper and video and mp3 player.
/edit:
Totally forgot:
Use llama!
You'll never have to worry about forgetting to set your phone on vibrate while at work and setting it to loud at home.
You can configure it so it only activates wifi at home and turns it off again if you didn't connect to any access point after a set amount of time. I haven't had to activate/deactivate wifi manually for ages without having to worry about it constantly searching for networks and sucking my battery dry!

Exactly what he said, but you can automate a lot of it by using an app called Tasker. I use it to sync all data on my phone for 3 minutes every 4 hours so it's always up to date. It can also automate the GPS on/off depending which app I use so it switches on when I open CoPilot and turns off again when I close it.
Tasker can also replace Llama if you can find 'profiles. to do it. Llama looks pretty good though.
I think the biggest drain is the display. With auto brightness on, the sensor will monitor the changes in your surrounding every second the moment you turn on the screen. Turn that off and manually control the brightness save a lot of battery.
Or just use lower autobrightness script.
I use Invisibright. Long hold on search softkey + slide enables me to set the brightness to whatever I want in a second no matter what apps are running.

It is still useless as your sensor is still working every time you turn on your screen. The sensor is draining your battery. Not the brightness value.
Autobrightness sensor drain
So you think that there is a greater drain from the light sensor than from an uncontrolled screen brightness?
Interesting thought. I'll manually set my brightness level a round20% for the next charge cycle and see what effect it has, though I suspect that as my display currently accounts for 20% of battery drain it won't make all that much difference.
I use juice defender and I think its actually working.
