Basically, when I leave wi-fi on my phone has incredible battery life. If someone has already mentioned this feel free to bury this post, but to my knowledge it doesn't seem this has been posted yet.
With wi-fi off and 3g on
- Battery lost 5-6 percent per hour
Wi-fi on
- Battery lost 1-2 percent per hour (sometimes less than 1 percent depending on what your doing)
Right now after having my phone on for 34 hours my battery is still at 70 percent! I'm fairly certain this is because it disables the 3g radio altogether which apparently is a real battery hog. That or maybe my phone is just a fluke. I really don't know.
This also seems to be tied to the htc sense rom (correct me if im wrong) but if i remember correctly battery drainage increased when wifi was enabled in the stock rom. Currently, I'm using the latest htc sense rom from modaco, I'd really enjoy hearing if enabling wifi helps others extend their battery life.
your having better battery life with the Desire ROMs? that odd, my battery life with a Desire ROM was 20-30% worse compared to stock.

Actually, it's a well known fact that 3G uses more power on most (every?) phones than Wifi... so you're not alone.
Hey when you say WIFI on..do you mean WIFI and EDGE or did you completely disabled the radio?
I never would have thought having wifi on would extend battery life to such a great extent though, in most of the latest cell phone reviews and what not everyone recommends to have wifi off saves battery life but in this case just the opposite is true. I kinda knew the wifi was more efficient but I never expected such a large benefit from leaving wifi on all the time.
@ram130 I haven't actually touched the radios at all so I expect them all to be on or at the very least have edge on, I am able to receive and send calls and txt so I'm assuming at least some cell radio has to be on. All I did was use the htc sense rom and enable wifi.
The cellular radio is still on, but 3G/Edge (data) are disconnected. I don't know how Edge compares to Wifi, but 3G is a battery killer in comparison.

In other words you have "use 2G networks" checked right?
I'm gonna try this is now. I'm currently at 3hr 32m unplugged with 80% left. I have wifi enabled and on the stock rom. So I'll post back when I wake in a few a hours and see how it goes.
My only problem:
Wifi seems to disconnect alot during the hour regardless if sleep policy is set to NEVER. My wifi signal is -78dBm to -86dBm in my room and on channel 11(used wifi analyzer). Any suggestions why?
I have the same experience at home, I enable Wifi and leave the phone stay home for a couple of days and battery still 40%, when I go out and wifi is not connected, 3G kicks in and battery drops much faster.
I'm using cyanogen 5.0.4.1
Interesting. Did not know this!
I guess I won't feel so bad about leaving my phone on Wifi all day!
Also, does anyone know how much power is used by not having a radio signal and letting it constantly search? That seems to destroy my battery. But sometimes I am in an area with wifi but no radio access (deep within a building).
It's too bad this phone doesn't have UMA - that would make up for T-Mobile's lack of indoor coverage (at times), and probably improve battery life a lot in some cases.
But I have to say that on another phones I've used, especially WinMo devices, using WiFi instead of 3G seemed to always use more battery. But, it could very well be different on this phone...I'm definitely going to give this a try.
im not sure about the percentage but i agree,the battery drain is considerably more when searching for radio.im in a building most of the day and it doesnt take long.miss the UMA i had on my bberry.

I also Get. About 25% better battery on wifi
Well after 10hrs of the phone being on stand by I woke up. It was at 46%!! my god. Anyway I checked my email, read an article all taking around 15mins and guess what? I had 30% left!. I put it back to stand by for 3hrs and took a look at it and had about 16% left...
It is now charging after one hour with just 10min use of downloading apps ..Can ANYONE tell me why my battery is draining so much on wifi? When its on EDGE for the night after 10hr I would have around 70% left from a full charge. Anyone can help me out here?
I shall be getting a replacement battery for free Tuesday.
Stock android.

Did you set your phone to only use 2G networks also? If you're not charging, wifi will probably disable after not being used for a while..so it's probably rolling to 3G if you haven't disabled it.
I'm not saying it's convenient to constantly switch back and forth... but this explains why it may not be a good test of the battery life the way you're running it.

Well yes I have it on 2G only. Any thing else could be contributing to it dying so fast?
Well I found a way to use my laptop as an AP. So I connected my N1 to it and getting full bars(-41dBm) in my room now. No wifi disconnects so far!(maybe it was my linksys before ?).. So far the battery is at 86% with some 3D games, been unplug for 1hr 50min now. I'll put it to stand by now and see how it looks after 10hrs.
I'm on a stock firmware(not rooted). 2G only selected.
The way I understand it is as follows:
Phone is on STANDBY:
3g==2g* which are both more efficient then wifi (that's why the default wifi policy turns wifi off if it's not being used)**
Phone is ACTIVE:
wifi is more efficient then 2g/3g because:
1) It's waaay faster and thus causes less battery drain* and
2) The AP (router) is much closer to the phone then the cell tower so in theory it doesn't need to use as much power to talk to the router.
*http://code.google.com/events/io/2009/sessions/CodingLifeBatteryLife.html
4:45min into it there is a power usage chart and 3G/EDGE idle power usage is about the same - also somewhere else in the video they talk about wifi vs 3g usage when transferring data.

Someone needs to test this ok. ...already testing wifi
Ok I'm at 11hrs 30min on wifi and its at 67% with light usage(checking email, news for 5min)..improvement? kinda, because since turning off my laptop it switched back to getting low signal(-81dBm) from the router in the next room. Weird? I'm still thinking. anyway I'm heading out so gonna use the phone more today, lets see if it gets me through the day.
Still no where near the thread starter 30hrs!! Maybe stock really sucks? bad battery anyone??
@ram130 I'm not sure how my battery is lasting as long as it has so far. I'm up to what would be an insane number, 65 hours 36 percent left .. this battery just wont die. I haven't the slightest idea how it's lasting this long I just leave wifi on all the time and turn wifi standby off. If anyone could explain how leaving wifi on more than quadruples my battery life I'd sure love to know.
I'm sure there are others who have experienced this problem. Even though I show no wake locks my phone drains at an unacceptable rate while on my Wifi at home. My phone can have a 60% battery when I go to bed, and be almost dead by the time I get up. The only clue that shows up in Android System Info or Spare Parts is network usage by '0' which is something with root access.
This is happening regardless of Rom. I've tried stock, Syndicate Frozen, Urban Fury, Bonsai, Stock Plus, and maybe another I'm forgetting. They all drain the crap out of my battery with wifi on at home so obviously this isn't a rom issue.
This leaves me to believe that either something on my network is forcing data to my phone keeping it from deep sleep, or the router itself is the cause. Turning on my phone to 3G, my battery life is spectacular overnight. It deep sleeps like it's had a case of beer with a bottle of nyquil as a chaser before bed. 1% an hour.
So, I've ordered a different router to see if that's the issue. I've googled my current router which is a D-Link DIR-655 and seems like others have had similar battery drains using that router but no one can emphatically say it for sure is the router. Guess we'll see when the new router arrives if it is indeed the DIR-655. Otherwise the next step is disconnecting everything else that is connected to my network (3 computers, 2 printers, XBox, Wii and a Blu-Ray player. I just wanted to point out to anyone else having issues with wifi and weird battery drain, that it may not be the phone that is the problem.
I too have massive battery drain when using Wifi. It doesn't matter what Wifi network I'm attached to (work/home/friends/etc), I burn about 10% + per hour on idle; whereas on 3G is burning only ~2%/hour on idle. On stock, Wifi was my battery saving grace.
I've just given up on using Wifi for daily use. I use 3G for everything now.
I hope the newest version of SFR (whatever the new one will be called) will remedy this problem I have. I haven't posted about it in the rom thread since I had a feeling it was just my phone or another bad flash in CWM.
I've been using that OS Monitor app to try and find the problem. On 3G all the network interfaces have static receive and send amounts as long as I'm not doing anything that requires data. Connected to my home wifi, there is a constant trickle of data.
When I let the phone sit overnight, there was over 4mb of data received, even if I turn off any kind of auto syncs on the phone.
wifi settings
Don't know if this will work for you but you can try. In the wifi settings click the menu button and select advanced then set the wifi to never sleep. I know it's counter intuitive but I went to sleep last night at 61% and woke to 57%. Wifi has been fine for me since changing that policy in the wifi advanced settings.

Mine has been set at never sleep since I got the Epic in September, and I double-check after each custom rom flash. Good looking out though.

Same here. Mines always been set to never sleep.
Edit: I just tested my phone on my work's wifi network. CPU Spy says it's going into deep sleep just fine. OS monitor shows a static data received/sent number once I was connected. Obviously something about my home network is the problem.

That is my general experience, too. These settings usually keep my WiFi usage low overnight.
But some nights, inexeplicably, I will wake up to find a large battery hit from WiFi. I don't think it is my WiFi router's problem, unless there is some outage duirng the night I am unaware of. Come to think of it, I had that problem last night but did not investigate early this morning before I left. When I get home, I will check with my laptop to make sure my router is running.
I have noticed this too and in particular over the past few days. I'm on the latest bonsai build which does have amazing battery life on 3G but now wifi does draithe battery much more than 3G. This never happened before. I have had my wifi set to never sleep. Any other suggestions?
Obviously haven't tested it overnight yet, but I shut down my one laptop and the constant data trickle immediately stopped. Right now it's looking like something my computer is running might be the culprit. Going to leave it sit overnight to see how it goes.
I found the cause of my drain! Narrowed it down to something from my laptop as when I shut my computer down at night, the drain would go away. The culprit was the HP Printer software for my wireless printer. Once I uninstalled it, the drain went away. Noticed in resource monitor that HPZinw12 was sending a constant stream of data from my computer. Why in the hell it would be also sending to my phone keeping it from sleeping seems pretty odd, but I recommend if anyone else who is having battery problems over wifi and happen to also have an HP printer, you might want to look into this as well.
I'd also add that my solution to getting rid of the problem and still being able to use my printer was just to uninstall the crappy HP software that came with the printer and add the printer through the control panel and let windows 7 install it. It doesn't throw on that HPZinw12 file that apparently polls the entire network constantly.

Since I have been experiencing similar symptoms intermittently and I also have a WiFi printer, I have tried to eliminate this as a potential cause. (I don't run an HP control app on my laptop, but already map the printer directly in Windows 7 like you suggest.)
In my case, I still get the excessive WiFi battery drain, and low battery level upon waking, sometimes overnight. But other nights the problem does not occur. So lately I have made sure that my laptop and printer are powered down before bedtime. And like you, a always have my WiFi sleep policy set to "never" and have a strong WiFi signal. But last night I still had the problem, and awoke to find the battery drained to 45 percent instad of its typical 90 percent.
Interestingly, I noticed not only high WiFi battery usage but also high "Cell standby" usage attributable to the well-known Time Without Signal problem -- and this despite my habitual use of the Airplane toggle workaround, which usually works.
Somehow, something caused both WiFi and cell radios to go crazy overnight.
BTW, I run a stock, unrooted Epic.
So far with SRF v1.1.1, my Wifi is back to normal.
On my work network, I've dropped 4% in 3.5hours with my work email syncing every 15mins. So that's pretty good usage given that sync interval.
I also do not have a printer at home, so the printer bit wouldn't have been a cause for me.
While the printer thing took care of the biggest problem for me, I still don't get as good of battery life overnight leaving my phone on WiFi rather than 3G. There is still something my computer is doing that wakes my phone up occasionally, but at least I'm not going to bed with a 70% battery then waking up to a dead phone. At least I have it narrowed down to one computer (total of 3 on my network), as when I shut that particular one down battery life for my phone is back to 1% an hour while sleeping. If I had to take a guess at this point, might be something with media sharing as I use that one as my primary location for music/videos to stream via Windows Media Center.

How do you know it is your computer? Have you tried just turning it all the way off?
Do you watch the services running on your phone? I routinely stop the DRM service, for example.
Except for the mysterious episodes when I experience this intermittent problem, my overnight battery usage is typically about 1 percent per hour.

I've tested over a few nights with a mostly full battery off the charger and reset the timer on CPU Spy. The nights I shut that computer completely off, I get very little battery drain and the phone is mostly in deep sleep according to CPU spy. When it's on, the phone shows a good chunk of CPU at 800mhz and more battery drain.
I've had my N4 since the day it was released and the battery has been generally acceptable.....until I upgraded to 4.3 (stock, rooted).
BetterBatteryStats is indicating the suspend_backoff wakelock is rampant. WakelockDetector is showing I'm only getting 20% deep sleep on days I'm only lightly using my phone. On Android's Battery screen "Android OS" is listed as the top culprit, consuming 40% or more of the total battery.
Google/XDA searches indicate suspend_backoff is related to Chrome, but I'm convinced this is somehow a wifi connectivity problem as this wakelock ONLY happens when connected to my work wifi. On the weekends when not working my battery is fine and I don't see suspend_backoff. If I don't connect to my work wifi while at work suspend_backoff does not show up at all and I'm deep sleeping at 80%.
Unfortunately at work I don't have the capability of configuring/swapping wifi hardware/settings, so I'm limited to finding a solution on my end. Hopefully the solution isn't to have to sit on mobile data all day long instead of connecting to my work wifi.
Any suggestions?

In Settings, Wifi, Advanced Settings turn Network notification and Scanning always available off and see if it helps. Drainage can also be an issue when the Wifi signal is weak, but it can be Google Now! related among other things, Now! likes to give you fresh cards like traffic, news, nearby things and weather, turning Now! off entirely (voice search still works) could still be help. Also using other apps than Google. I know, hardly a real soluton but I replaced as many as I can.
No, wifi scanning is irrelevant since OP wants to use wifi.
What radio are you on OP? I'm assuming .84?
Yep, .84 radio, Google Now is disabled
Anybody?
rom kernel info? screenshots of the issue?
Back in the Galaxy S II days it was related to Google Chrome with the tilt scrolling. I always disable it though.
Sent from my Nexus 4 using Tapatalk
I am experiencing the same issue starting from yesterday, God knows why. The most common advice is to disable tilt-scrolling in Chrome but as far as I could see the Development Tools option has been removed from teh settings. Any other ideas?
could it be because you're using Touch Control for S2W or D2W?
Your work's wifi may have a combination of 2.4 and 5 GHz signals. I would get this wakelock if I allowed android to choose automatically which band to connect to, but if I forced either 2.4 or 5, the wakelock would let up.
Lookas a kernel bug, which has been fixed in teh latest Franco's release.
It has been a fairly commonly reported problem (like for instance http://forum.xda-developers.com/showthread.php?t=2133176) when packets from a wifi network keep a device awake and downloading information all the time. This apparently started with ICS/JB and has never been fixed. On older devices it shows up as wlan_rx_wake but on the Note 3 it doesn't show up in any wakelock detector and is just a huge Android System keep awake time
On (school) wifi, I am getting about 80%+ wakelock time due to this issue. Even with all cellular antennas completely off, it drains about 15-20% an hour. On a device with a battery as big as the Note 3, that is a significant amount, and is further backed by the fact the in BBS the kernel has a data usage of about 300MB/hour. I used Network Log and see that I am getting packets from almost 1000 devices on the network, all at school.
Do any of you have the problem or any suggestions for fix? Most suggested fixes don't work as they are mostly router-side, which I have no access to. Since Verizon sucks big time here, my options are force 1X (5%/hour drain), force 3G (8%/hour drain), try LTE (like it will ever connect), or wifi (huge drain). Or is there any way to bring this up to Google/Samsung?
I have the same issue on my Note 2 and 3 with my Netgear R6300 and it drives me INSANE! I need to try another router.

Yes, I had it on my Note 2 as well, but it didn't drain nearly as fast. Makes me miss my Razr Maxx which had better reception and did not have this bug.
On a side note, I have a R6300 at home and it doesn't have the problem with the Note 3, you may be better off investigating the router settings first before buying another.

Give GSam Battery Monitor from Playstore a go. It can give you an overview of whats using your juice.
Alternatively you can use Better BatteryStats: https://forum.xda-developers.com/showthread.php?t=1179809
If you are rooted just install the XDAedition from post #2
If not rooted then follow instructions in post #4
Definitely some rogue app running in the background...
As mentioned above, use an app to monitor your battery. But I would also suggest installing an app to monitor your data usage, because sometimes your connections and data transfers are the culprits in battery drain.

Ok, so I've been observing my battery for over 2 days now, and it seems that the problem is my cellular connection. I took the sim card out and noticed that the battery hasn't drained for several hours. But I wonder why my galaxy s8 is having this problem, the sim card I'm using on my galaxy s8 is the one that I've been using on my galaxy s7 for the past several months and I didn't experienced the same problem on my galaxy s8
Is your network signal weak?

This is a strange issue because usually battery drainage happens because of background updates and data transfer of certain apps.
Can you try turning off your mobile data connection and see if the drainage persists? You need to isolate the issue in order to identify it
can confirm that switching data to 2G network vs 3G/LTE has drastically improved my standby time, massively, especially if there is no 3g/LTE in the area, the phone hunts continually for 3G/LTE thus draining battery, but after switching to 2G no problems, just means that internet is damn slow...
You can try hibernating apps that you rarely use. Also, phones tend to seek LTE; if it happens to be that you are in an area with bad carrier coverage, turn off your LTE.
On the other hand, try to uninstall unused apps and turn off Always on Display.
edit: also, check the battery usage of your apps. In my case, Facebook, Tinder (lol), Spotify, Messenger, and Snapchat are the apps that consume my battery a lot. Device Maintenance usually prompts me that about an app excessively using the battery. Nevertheless, hibernating apps would definitely help.

Do you know if the device would still be searching for LTE constantly if Wifi is connected? I'm just curious, I live in an apartment that has almost 0 data, and phones tend to pick and choose whether they want to be on 3G or LTE here. Definitely would be a drain, but I don't know if it matters if I'm on my wifi network..

Device Maintenance usually prompts me that about an app excessively using the battery. Nevertheless, hibernating apps would definitely help.

I did a factory reset on my phone and let it just sit for the whole night. I left it with it a 100% charge and after 6 hours, it drained 20% of my battery

can confirm that switching data to 2G network vs 3G/LTE has drastically improved my standby time, massively, especially if there is no 3g/LTE in the area, the phone hunts continually for 3G/LTE thus draining battery, but after switching to 2G no problems, just means that internet is damn slow...

My carrier doesn't support 2g anymore. Also, switching to 3g still doesn't stop the battery drain

This is a strange issue because usually battery drainage happens because of background updates and data transfer of certain apps.
Can you try turning off your mobile data connection and see if the drainage persists? You need to isolate the issue in order to identify it

I turned my mobile date off and still got battery drain, and maybe a lot worst this time. I got 3% drainage for about 30 mins of standby. I have my wifi turned off

Try to install a data manager/tracking app and another battery tracking app and see if you can get any tangible stats out of those.:fingers-crossed:
I think this may be my problem

I don't know, I just found this website and found out that there are just few LTE/3G bands that my phone supports, could this be the reason why? anyone?
My usage for the last 2 days until I decided to put a SIM card and enable data
Wow, this thing's battery is inconsistent. Good one day, bad the next. Within 2h 26m, my phone dropped 12% with only 27:38 screen on time. I listened to maybe 4-5 songs in Google Play Music.
Anyone know why Samsung DeX Home would be taking up so much space, and why playing only a few songs *that have been downloaded* is causing a decent drain through GPM?
Not sure what the deal is with Android System Kernel, but it looks like the wakelock is from audioserver.
My S8+ battery performance was not very good since I started using the phone. Installed GSAM and granted it the needed permission via ADB. Recently battery drain has been terrible because mainly of Google Play services as well as FB. Battery only lasted for barely the whole day and sometimes I had to recharge during the evening.
After a lot of search and trial and error including disabling all Bloat ware apps using BK Disabler (as per a post at the beginning of this thread) and which caused more problems actually, I re-enabled all apps again. I installed Greenify with Agressive Doze enabled and Greenifying system apps enabled, but that didn't help either.
Finally, that's what I did and which gave me for the first day since I used the phone 4h15m of SOT and still 54% of my battery remaining!
1- Apps installed: Greenify, BK Disabler (with plug-in), GSAM and Play Services Info.
2- with BK Disabler I disabled all FB related apps (Facebook, FB App Installer, FB App Manager and FB services) and installed instead any 3rd party app like FB Lite, Swift FB, Metal or Friendly.
3- Disabled FB Messenger and installed Messenger Lite.
4- In Greenify, I disabled Agressive Doze and Greenify system apps.
5- I installed the latest Google Play Services Beta app version 12.2.09.
6- I am using Power Saving mode with FHD+ but will try tomorrow without it.
The battery drain was dramatically decreased knowing that I am using 3 email accounts (Gmail, Hotmail and Good for Enterprise), LinkedIn, Instagram, 2 What's app accounts via Parallel Space, Swift FB, Messenger Lite, Telegram as well a bunch of other apps. I am usually using 4G and Wi-Fi while at home with a lot of FB and web browsing.
Hope this post shed some light and help on battery drain issue with the S8+.
Ciao
Note: I had 8+ hours SOT yesterday!!
