Ever since I got my SGS3 last year, I noticed that WiFi would drain battery rather than save battery. For whatever reason I always got better battery life with WiFi off rather than on.
I noticed a lot more wake locks too. I don't know if it was because with a solid WiFi conneciton, apps tend to refresh a lot more than they normally do.
Enter the HTC One. I have noticed the same type of effects. I've only had it for 2 days but I am noticing better battery life without it.
So I want to collect some data using a poll. Do you get better battery life with it on or off?

Can you please add your vote to the poll? I just want to resolve this for people complaining about the battery life. It might be their WiFi.

My best setup is with wifi always on, but I set it up so Tasker turns mobile data off as soon as my phone connects to my home or office wifi network.

Shouldn't mobile data turn off automatically when WiFi connects?

It goes inactive, but it doesn't actually get 'turned off'. If I don't have it turned off, what happens is when my wifi goes to sleep then mobile data goes back on. I don't want that.
of course you get better battery with Wifi turned off. but doesn't Wifi consume less battery than cellular data? my balance is to keep Wifi on ANYTIME i'm in a trusted wireless network and manually toggle off cellular data when I'm using Wifi.
It burns battery when it isn't connected and on but I get better battery with it on and connected

Hello,
i have a galaxy s2 with checkrom revo4 snd kernel siyah 2.5.1. i am pretty satisfied with the battety except with wifi.
if i leave wifi on, my phone will run out of battery in 10-12 hours even with minimal use (screen on time is about 1 hour). that means the battery drains 7-8%/h when the phone sleeps.
i saw some people phone which lasts 30 hours with wifi all the time (not sure he is on an extended battery).
so i really want to know if this kind of draining is normal? if not is there anyway to diagnose the problem and fix it? thank you very much.
i attached a screencap of my battery usage.
Do you have a d link router?

Bottom line keeping your wi-fi on is going to drain your battery way faster. I'm not sure why you would need to keep it on for 10 hours.. even 30 hours.
Perhaps the stats you saw lasting that long had all other radios turned off? That is the only scenario I can see something like that working.

not always. If wifi is always on but not connected then it will be constantly scanning and draining battery. But if its connected, (i.e at home), then it can save you battery depending on how good your network reception is. I get poor reception at home from my network and so if i turn wifi off but leave the syncs on the battery is working hard to try pulling in enough signal to work. I leave wifi on and i lose virtually nothing overnight.
edit: just to add i use checkrom v4 too with speedmod 18 and dont have any issues
I've been having exactly the same problems with this ROM and pretty much any kernal. Haven't been able to find a cure.

There have been a few threads where users have had similar issues wifi draining battery and the d link routers causing this.
Do a search for them some users suggested updating the router firmware, another flashed dd-wrt and for them that stopped the drain.

I keep getting contradictory information. Some say that the Kernal affects wifi performance not the modem, others say its the modem that affects wifi.

There's no option to set it to turn off automatically when the screen's off on my phone in the WiFi sleep policy menu. An app called Tasker can do it though, as well as setting it to turn off all data when the screen is off, etc.
My fix with an updated DLink DIR-615: change WPA2 Protection from TKIP+AES to AES (TKIP only did not work with my i9100). In G Only it seemed draining even less (quick test), but I got this router for N+G and it seems working now.
One thing I found to save power that I don't really see posted anywhere is by using this app: https://play.google.com/store/apps/details?id=AutomateItPro.mainPackage&feature=more_from_developer#?t=W251bGwsMSwyLDEwMiwiQXV0b21hdGVJdFByby5tYWluUGFja2FnZSJd
I have it programed to turn off 3G/mobile data when it screen's off....unless I have a certain app running like say the browser. It will then keep data connected until the browser is closed, then the screen turned off. I then have it turn 3G/mobile data on as soon as I screen on again, so it's ready to rock instantly. I personally noticed a huge difference in my battery drain when not using the phone.
The app is pretty cool, you can program a ton of things. I have gps auto turn on when I use G-Maps or GasBuddy, then it auto turns off when I close those apps. Saves time and juice imo. Just figured I'd throw this out there.
nice app. isn't there a setting within the OS to do this, though? pretty sure there is.
either way, agreed. data usage can/will cause battery drain.
the real perp is your display, however. adjust your brightness settings, you will see significant battery improvements.
My display is set low, and all my other settings are set to be battery friendly. It's been awhile since I used the app. But after I had that setup, I noticed better life instantly. Went fishing today with the little guy, left the house with 100%. No phone usage for 2hrs, and it was still at 99%.
Can't you do this without the app tho

If there's a way to set the phone to turn the radio off when screen is off, I'm unaware of that. I tried turning it on and off manually, but it got to be a pain turning it on and off all the time. I would end up just leaving it on. Now I don't even have to think about it, and it gets done everytime.
Sounds similar to Tasker, which is a little confusing to new users.
But as for your post, turning 3g off saves a TON of battery. I have to keep it on during the day to get emails for my job, but at night, I turn 3g off, and the phone will drop maybe 2% overnight with 3g off.
The CDMA version of the 3D has a setting in network that allows you to turn off your mobile network if the screen is off for 5+ minutes. The setting is "turn off always on mobile network". But the screens needs to be off 5 minutes before it will. This setting will not turn off wifi though.

If you wanted to save battery life without downloading anything you could just use the HTC widgets for mobile network, 4g, WiFi, and GPS. This method allows me to switch the settings on and off on the fly. I've also found that if you disable all GPS options it won't be running in the background and for apps that require it. And if I'm in one spot for a while I just use WiFi.
Hello. I picked up my s3 this morning after having charged that night. I unplugged it at about 1 in the morning, with airplane mode on, bluetooth off, and WiFi connected. When I woke up though at 10, the battery had dropped down to 80 percent while in standby, with no recent apps even running. I'm not sure if this is normal or if it's a battery problem but it's quite annoying, because it drained 20 percent in 9 hours of standby. Any help is appreciated.

I will drain the battery and charge to full again tonight. After I check it in the morning, I'll note what the battery stats say is draining it. I don't want to do it right now because it's been influenced by my usage today.

The things that it's say are draining it according to the usage stats are: WiFi, android os, phone idle, and android system.

Hmm. This could be my problem, but I'd need to try out some other WiFi networks to make sure.
Sent from my GT-I9300 using xda app-developers app
Maybe caused by ~LG8 OTA combined with dual-band WiFi network?
I posted this over in another forum, but copying here to see what you all think...
..............
I don't know this for a fact, but I've read some things that lead me to believe the issue may (again, not confirmed), MAY be related to the recent ~LG8 OTA push. The root (no pun intended) cause is related to how the SG3 interacts in 802.11n band Wi-Fi networks that utilize multi-band (i.e. 2.4Ghz combined and 5Ghz running simultaneously).
One of the "features" of ~LG8 was to remove Advanced options for Wi-Fi networks, switching the connectivity logic to "automatic." If a GS3 is in a multi-band 'n' Wi-Fi network, it MAY be switching back and forth between bands, thus chewing up battery without actually pulling any data.
This is unconfirmed, so don't shoot the messenger. Can any of you validate whether or not the Wi-Fi networks where you see excessive drain is indeed a multi-band 'n' network?

This sounds like it could be a possible cause. I'll have to try out some multi band n networks in the next few days or so and see if there's any effect.

I use the app 2x battery on the play store, and it is excellent at turning off data and WiFi when the screen is off.
Which leads me to my question. Does it save battery leaving WiFi on, than turning it on and off whenever the screen is toggled? I know WiFi has much better battery life than data.

I would think just having WiFi turned on with screen on saves more than having it turned off while screen is off. Just because if your on data signal strength can vary and can be worse than WiFi from data pulling signal which = battery darin. I usually just leave my WiFi on 24/7 and toggle it off if I know I'm going out for a while.

It's a simple question really, and I agree with you for sure. The battery lost turning it.on and off would seem like more than leaving it on and using an app like greenify to tame apps and sync.
So I've been enjoying my ultra for the last couple days. Battery seems great. But losing percentages of battery at standby caught my eye. My phone would die when I wouldn't even be using it. So yesterday I found the culprit. Mobile network on all the time kept draining it. I disabled it and enabled wifi at work and home and now the battery lasts for days. Just a quick tip.

In every phone that's the main reason for battery drain on standby.
You could set Stamina mode to disconnect some functions you don't use while the screen is off, and leave on just the one that are vital (for you).
Anyway, another reason could be the signal strength in your area: if it's not strong enough, the battery drains because your smartphone is constantly trying to get the best signal (between 2G, E, 3G, H and H+) for its connections, and that is VERY battery consuming.

I got it when I am home. Poor H+ signal and 3G signal, so it always switch between H+/3G/E and it result in bigger battery drain. I go in the center and keep mobile data open and no problem.
