I've just switched broadband provider and have noticed that my battery life is just awful compared to how it was with the previous WiFi connection.I could normally go a full day on heavy use and still have around 30% at the end of the night. The phone has been mostly screen off for about 5 hours and it has went from full charge to 16%.
I can confirm it is definately using a 5ghz signal as I logged into the router page and it was listed as a 5ghz connection.
Does anyone know how to make the Z3 run on a 2ghz connection instead?
I'm rooted (locked bootloader) and have xposed if anyone knows any modules which might help
This has to be set on your Router not on your phone.

From a battery perspective, should I use wifi? Most of the time i'm at home or at work where I have wifi. I also have good lte coverage at both. Speed aside, will I save battery by not using wifi or not?
You'll definitely save battery by using wifi when you can connect. I love the speeds over lte, but it is definitely a hog...
i also had boost of battery using WIFI
Using unlimited data plan makes me to consider using 4g, but I found that Wifi consumes much less battery.
Use wifi. The battery savings are huge.
yes i cant stress enough, wifi saves enormous amounts of battery so use it when ever possible. the difference is like night and day.
Compared to 3G
I've been leaving my wifi off since I have unlimited data and the 3G is pretty fast in my area, no 4G yet.
I've had pretty good battery life lately using only 3G, I'll have to do a few tests and see which one and I'm a fairly heavy user I'm approaching 4GB this month and none of that is tethering
3G or Wifi
Tested watching a streaming video of 22 mins
on 3G I lost 13%
on wifi I lost 8%
Wifi wins, of course standby is probably different, if 3G vs wifi loses this badly I'd have to imagine LTE vs Wifi is a slaughter battery wise
Actually I found something interesting...
For some reason, even when I am home using Wifi, the battery drains faster than I thought. Where I live is like a strange signal spot. If I turn off my WiFi I can see my TBolt constantly switching between LTE and 3G, sometimes it stucks on 1xRTT for a while then goes right back to switching between connections. If I am at work (downtown LA) where the LTE is pretty well covered, I still use WiFi at the office, the battery BARELY drain at ALL.
My theory is that even when WiFi is active, the phone somehow STILL does the LTE/EvDO switching on the background does draining the battery.
If somehow the devs or VZW can tell the phone to STICK to EvDO/1xRTT instead of going back and forth with the LTE while WiFi data is on, it'll solve the problem.
Also just FYI, I have the latest radio and BMAF 1.5 remixed.

pretty much correct. at least on the gsm side, when i connect to wifi at home, i can no longer see if the phone is on 3G or EDGE. but it definitely switches back and forth to those networks, while staying on wifi, you just dont see the icon switching, but its definitely happening. i dont see why cdma and 1x would be any different.
if this is the case then why don't you just turn data off when you are on wifi.

You are absolutly right! How come I never thought of that. Will do that when I get home tonight.
Thanks for the tip!

Better yet get juice defender and automate it . Its very good app. Right now it says I'm almost adding fifty percent on to my battery.
I seem to be bucking the trend here, but LTE is working better for me than wifi. I usually have a good signal, so that's part of it.
The other part is that my wifi may be eating more juice than normal because the TB and my router may not be playing nice together. Ever since I added the TB to the network, I've had to reboot the router every coupla days. Before the TB, it was solid weeks on end.
Has anyone who is still having trouble on with batter on wifi set their wifi sleep policy to "Never" sleep? Mine is set to this and if I am home most of the day I will lose very little battery through out the day.
I believe by default the wifi is set to turn off after a period of time or when the screen is off so during this time I believe you are actually reverting back to using the vzw network. To turn wifi to always on go to settings>wireless>wifi settings>hit menu>advanced. The sleep policy is at the top, change sleep policy to never. This my reduce battery while not connected to wifi so I always use the power control widget to turn my wifi off completely while I am away from the house.

Oh yeah this is very important, set wifi sleep policy to never greatly increases battery life. Otherwise it switches back to 3g when screen goes off and drains way more battery. This is very important to set this otherwise you wont see the increase.
Is strongly recommend switching to cdma only if yore gonna use WiFi and plan on saving your battery. Otherwise what's the point. I personally don't even bother using WiFi just use LTE only mode. I'm getting better speeds than most WiFi connections using my LTE.

I'm wondering if anyone else has encountered this.
I don't have 3g signal or wi-fi at work, but I do have a laptop connected to a network. I use this trick to create an ad-hoc wifi connection from my laptop to my phone in order to get data:
http://www.brighthub.com/computing/windows-platform/articles/7785.aspx
I've been using this for a while, for both my Nexus One and Nexus S. On both phones, the battery drains significantly while connected via the ad-hoc connection. The phone idles at 200 or so miliamp/sec according to Current Widget, compared to 7 to 9 mili/amp/sec when idling on regular wifi.
Anyone know what causes this, and if there's a way around it? It seems like the phone is treating the adhoc connection differently than a regular wi-fi hotspot.
On my Defy I actually have a notification when connected to ad-hoc that this has implications on power consumption. So it seems it's normal. As to why this is so, finding out would probably require reading about the low-level workings of wireless networks. I'd guess it's because the two devices connected this way need to stuff themselves, stuff that is normally handled by the access-point.
Thanks for confirming that it's just not me. I guess it's unavoidable. I wonder if the constant increased battery drain diminishes the life of the battery.
I know this topic has been beaten to death but I haven't really seen any clear solutions to this. I'm running stock JB rooted on galaxy s3. My battery drains considerably faster when on wifi-standby. When on LTE, I lose around 1% every hour to hour and a half. On wifi, I'm losing 1% every 20mins or so. There have been some posts online about how this has to do with DHCP. I spend most of my time in a hospital so I can't really control the router and have the phone connect with static IP. I've tried using my friend's iphone 5 and it doesn't seem to have the same problem so this seems samsung specific. Is there any fix out there?
Your phone isnt sleeping on wifi for some reason most likely. Does it do it on other wifi networks too? Or is draining on the hospitals wifi only?

It's draining faster at my home wifi also. In 2 hours, the phone has spent 28 minutes in wlan_rx_wake.
Phone radio is killing my battery on a S6 & Wifi signal is very poor - please help?
Hi folks,
I'm new to these forums and having read through more posts than I remember I think I need some help - apologies in advance for the length of this post!
I bought a S6 approx 4 weeks ago, having had the S4 which served me well. I immediately noticed two issues
1/. Battery drain
2/. Poor Wifi signal
1/. My battery drain is currently unacceptable, I charge to 100% and unplug overnight so screen is off - I wake up 7hours or so later to find it has drained overnight to 75% or even less. I have power save mode on ALL the time, I have disabled all the non essential and probably some essential apps such google player etc. I have location, NFC, Bluetooth, Sync, Always allow wifi scanning, none of my apps are set to sync automatically etc switched off (having read all this good info on these forums). I installed GSAM and never saw any major issues although the screen would be showing close to 40% (I have black background and only on Amoled Photo display rather than the Adaptive display which is so much better!) I then read on a post today the GSAM Wifi profile had to be edited to 767 to show an accurate usage - I did that this morning and lo and behold I have a Phone Radio zapping 43% battery. Can someone please tell me how to switch that damn thing off or how it can be managed? I notice the battery issue is alot worse on wifi than using mobile data. I have attempted a cache reset post 5.1.1 update. Any other ideas on saving battery life would be very much appreciated.
2/. Wifi signal - I have a Virgin Media Superhub router on a 50meg connection. My S4 had no issues throughout the house picking up a very good signal and wifi speed was excellent. All other devices such as laptop and IPAD have no issues getting a good signal on both 2.4G and 5G On my S6 unless im in the same room as the router it is extremely poor and I'm guessing has also something to do with my battery draining so the two may go hand in hand? Again having read many posts on these forums I have changed my wifi settings DNS 1 & 2 to 8.8.4.4 - I haven't seen this make much of a difference though. I used the DNS SET app I read somewhere would also help but unfortunately the poor signal and slow speed continued.My battery drain is worse with Wifi so I try to use my data plan but im using that up very quickly and would love to use wifi! Does anyone know anything else I can have a go at?
I am loathed to try the factory reset option if there are other things I can attempt first to save me setting up the phone and my go launcher app etc. I have attempted to attach some GSAM screen shots but cant find an attach link anywhere?? can someone advise how to do this? more than happy to provide any other info. Any help would be very much appreciated - thanks in advance.
I have the low wifi signal problem too. My friend has an S6 and has also poor wifi signal at the same spot. Others phones like z3 compact or moto g2 have more signal than s6 at the same spot.
It's annoying.
So currently wifi kills more battery than 3g!
its been on an hour and already accounts for 13% of todays power use.
anyone know how to fix this bug?

this is hard but it could be many things, even other devices on your network in fact that's where I would first look, some sharing setting or some powersaving on or off setting in your router

5Ghz or 2.4Ghz?
Supposedly 5Ghz would drain more if you aren't close enough to the source!

Check for am app that's throwing lots of wakelocks or alarms when on Wi-Fi. Some apps think they have free reign to check in all they want when you're not using cell data.
@OP
Had the same issue beginning 5.1.1. Turned out keeping the phone only on 5GHz instead of both 2.4 & 5GHz wifi did the trick for me. Try it out if you also have a dual-band wifi router.

Many Playstore apps exist to measure wifi strength & effectiveness. "Wifi Overview 360", "Network Signal Info Pro".
My Sammy S6 has a much better wifi hardware than my cheap, old phones. But my home wifi routers are the same.
Wifi transmissions are bothered by:
1) poor hardware (old, cheap phones, etc), which drains battery with weak signals.
2) radio interference rubbish between the main sender, and your wifi receiver.
3) orientation of the two aerials, in relation to each other; horizontal, angled, vertical, ... (especially if 1), 2) above are bad
4) Whether the receiver unit is facing the main unit, sideways, backwards, frontwards, etc. On poor quality hardware, this is very important.
Being very crippled myself much of my time is just lying in my (nursing) bed. My Samsung Note Pro 12.2 floats above my head, in bed. Smartphones are affected if my head gets between the unit and the main unit.
My main wifi unit is about 20 yards/ meters away, but transmitting diagonally through a thick, metal-rod reinforced, load bearing wall. So I have a hardwired ethernet cable linked to another wifi unit under my bed, getting a faster, less power-wasting signal.
I have this on my work WiFi it drains the battery really quickly even idle it is about 1% per 5mins whilst connected to WiFi. On 3/4g it is significantly less drain.
But at home I don't have the issue battery life is good even on wifi.
It'd be nice to resolve it, have had it since I got my s6 in may so following this thread closely.
I opened my own thread back then which explains my experience a bit more:
