Right, I'm having issues with wifi on my Cromi-X 4.6 TF700. Battery drain is usually over 90% on wifi, and signal seems very low even when just a few meters from the accesspoint. What really pisses me of, is that I get neighboors wifi's at about the same signallevel, some of them on the other side of the street, while i'm getting a poor signal from my Apple airport express is sitting just a hands reach away from my tabel. I have tried moving the accesspoint, and also used a old d-link gameloung router to see if that helped, but signal strenght and battery drain seems to be about the same.
Since I'm seeing neightboors wifi, I somewhat doubth there's and actuall hardware issue. I have tried moving channels on the accesspoint, but that seems to have minimal impact.
Any advice on a good accesspoint that seems to work really well with the TF700?

I don't think it's actually the WiFI draining the battery more like you have lots of active apps using wifi when the machine is sleeping thus wifi is kept on. Download WakeLock Detector from google play to see what is keeping the device awake over a period of time.
Also try wifi analyser as well and see which channel it recommends. Wifi channels get pretty congested these days and it could be as simple as that.

Wakelock downloaded, will see what that tells me. I have tried changing the channel, but it has no or little effect. Just from my small neighboorhood I can see 10+ Wifi's from my livingroom, so yeah it's congested alright.
Am I right in beliving that power consumption goes up when signal levels drop?

Yeah but try wifi analyser it maps out your neighbourhood by channel and will show you.
Yes if it is having to work harder to stay connected then you coukd see power cosumption go up. Try wifi fixer from the play store as well. I use it on my prime and it works wonders as that has a much weaker signal.
Have been running wakelock for about 14 hours now, all triggers are at 1% so that seems okay. Google play music seems chatty, otherwise not much. How much battery drain % does the wifi normally show? I use my tablet for surfing, forum and mail only, so wifi is running constantly on use.

If your connected to wifi and using it, are you gonna get better battery life VS being connected to either 3g or 4g/hspa+?
and Why if so?

This is the General forum. To answer your question, Yes it would use less battery on WiFi. On a data connection the signal is not a constant and the phone is always looking for a stronger signal.
Thanks, thats what I thought. And ive noticed that connected to wifi my battery lasts a lot longer.

yes. And 4g eats your battery.
When I am only using the phone for data, I use WiFi when available. I turn on airplane mode then activate WiFi.
I don't know about that... when I'm on wifi my battery drains like a mofo. Weapon 3.0 ICS theme faux 1.3 kernel.
On every ROM and Kernel I've tried, Wi-Fi uses much, much less battery than 4G. I haven't tried any of the toggles / battery saving apps though so I'm not sure what effect those might have.

He shouldn't have to. If he's draining faster on WiFi then something is screwy with his setup.
On stock, cyanogenmod 7.1, and cyanogenmod 7.1 with various other kernels I've experienced increased battery drain with wi-fi on and connected with the phone sitting at home the entire day. Turn off wi-fi and let it just use the data connection to T-Mobile and I get drastically increased battery times. I'm assuming those of you who get better battery with wi-fi on are in extremely bad signal areas. Also, if you're on cyanogenmod have you turned off the auto wi-fi disconnect when sleeping feature? If you haven't then your battery life when sleeping should be the same as that of wi-fi turned off.
Wi-fi should always be priority if your in range.
Well my personal experience has been that wi-fi eats up battery like crazy. Same thing happens to the other smartphone users I know around here so I was surprised to see that people get better battery times with wi-fi on. Are you guys completely turning off your cellular radio? I don't like the quality and slight delay of wi-fi calling so my cellular radio stays on when I have wi-fi on.
I don't usually notice much difference between wifi and 3g battery drain here (no 4G for tmo here).
As someone already posted, my drain is worst when 3g signal is poor, like when I'm at work and the metal building interferes with everything.
Have you tried checking logs while connected to wifi to see if maybe some app or service goes crazy?
Nothing fishy going on when wi-fi is on. I get about 10-14 hours on battery with wi-fi on and next to no use of the phone vs somewhere around 20+ hours with wi-fi off and similar extremely light use. I keep meaning to do some more standardized testing where I literally don't touch the phone but life gets in the way and I have to make/answer a call or txt or whatever so I can't nail down any hard numbers. Typical experience on a slow day for me is that if I forget my wi-fi is on, my battery will be somewhere in the 3-5% range when I'm getting ready for bed while if I hadn't left it on, I can go to sleep and wake up and it'll still be hanging in there.

That's true, I've always believed that Wifi eats battery faster because someone(don't remember who) always told me that Wifi uses more battery because it processes data faster, but I always noticed that when I used 4g, it drains a lot faster.
I always blamed it on the ROM, but I can see that it's not the ROM's fault.
I'm just going to start a list of feature/improvement requests:
1) WiFi- the signal is much improved from the 201, but is killing the battery. I routinely see the WiFi using >50% of my battery. I noticed that even when it is on, but not connected, it still is chugging along, slurping battery. I suspect that scanning every 5 seconds is doing this, even when connected to a network. Its just Constantly scanning. On a cell phone w/ a mobile network where people are in motion, i can see this as more necessary, but not on a WiFi only tablet. Is there a way we can kill the scanning when connected and only scan if requested manually? It's nice that things pick up automatically on start up, but then it largely becomes redundant after you are connected. Some adjustable settings on that would be nice. Battery life would improve a bit i suspect.
Edit: i tried a little experiment, WiFi doesn't scan every five seconds, i counted about 30 seconds. I tested by reading the observed networks on one side of my house where i can weakly pick it up, then walked to the other side where i couldn't and counted how long it took to go away automatically. That is 2 scans a minute, 120 an hour. Tell me that doesn't affect battery life for no good reason, especially when I'm connected to my WiFi already.
More to come as i run across them.
Sorry your test is rubbish ^^
Connect your router via LAN to a computer. Goto your router log and see how often the infinity tries to talk to the router.
That would be a more realistic time
>implying Asus will listen to a lowly consumer like you or me
From where do you draw the 50% WiFi consumption, the standard Android battery app? It is flawed. Check your battery consumption in BetterBatteryStats, that works far better. Then report back in.

I agree, I've never been able to really understand what BetterBatteryStats is trying to tell me. I've used it to find apps that were stopping deep-sleep from working, but beyond that, I haven't really found it very useful. Very hard to interpret.

2 Stereo Speakers
Think they heard me? Why why why can't ASUS put decent speakers on this thing. Or at least if they put one, why can't it be a speaker that someone other than my dog can hear?
Larger battery capacity.
Prime and Infinity both have the same battery size, yet Infinity runs at a higher clock speed, thus using more voltage and has a higher res screen.
So as most of us already know that the WIFI when it is actively in use e.g. browsing, it drains a lot of power. Essentially, the battery consumption doubles when when actively browsing in comparison to the playing local video (~20%/hr to ~10%/hr). This does not happen on any other device I have used in the past.
Today, one forum user said interesting thing:
SmartAs$Phone said:
In fact the WiFi is so cranked up on these baby's (same as for Primes) that it uses as much or more battery than the screen, and it's a pretty hungry screen! I wondered why they kept the WiFi pushed so hard on the Infinity, was it that Asus wanted to show just how great it could be (and other than no 5 ghz. radio, it is really quite good - I get roughly 4 times the throughput I had with the Prime, and twice what the TF101 could deliver) or was it just leftover coding from the Prime?

Not sure if this is true, but make sense if the latter is true. I wonder if there is anyway to turn down the power supply to the WIFI unit because I like my infinity with ANR pretty much now gone, beautiful screen, not real IO issue (for practical use), my only complain is actually battery consumption of tablet alone when actively browsing. So if this can be fixed, it would be phenomenal news for me.
I personally don't know. But anytime you have radios on, there is going to be additional battery drain. Not saying Infinity's isn't excessive.
You could try using the Power Save mode.
Unless I have the screen on, when the WiFi is turned, I can go all day This is just checking email, IMs, little web, and so forth. I do have a C8 release.

It's definitely true the WIFI component should drain battery; however, I think in infinity it is excessive when compared to any other tablet. And you are absolutely right that just having it on does not drain much but when actively browsing it does. The easy way to notice this is, if you watch video (local) the tablet alone can last up to 9 hours i.e. 10-12% per hour battery drain; however, as soon as you start active browsing not even streaming but simply surfing web it becomes ~20% per hour drain.
Sometimes antenna like devices can increase its signal gain based on how much power you supply to it. So the other guys post made sense to me in theory at least.
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?

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.

What's the best way to find out with out root

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:

Dear all,
I have a Pixel 2 and am having some issue with battery life. Some days, it is crazy good: I leave my phone at 100% before going to bed, and I find it at 100% when I wake up in the morning (about 7 h of deep sleep for both me and the phone). Some other days, I lose about 40% over the same period of time. In both situations, I don't touch the phone from when I go to bed until morning. Bluetooth is disabled, WiFi and Mobile are enabled. My WiFi router is always on and I have very good cellular signal.
I thought that a rough app/wakelock could be the culprit but, using BetterBatteryStats, I have not been able to find any. The only unusual "process" seems to be one that is called "No Data Connection" and "No or Unknonw Signal", which show up as 87%, whatever that means.
Does anybody have any ideas as to what could be the source of the problem?
Many thanks!

Losing 40% charge in standby mode is a serious issue. Could be a defective battery. Why don't you return the phone to the store you bought from and get a new one?
Sent from my Pixel 2 using Tapatalk
Maybe you have dodgy mobile coverage where you are? If signal is weak or in/out of service any phone will use a lot more power trying to stay connected to a tower it can find. You may also experience that a phone seems to 'camp on' to a tower with a weak signal (consuming more power) even when it sometimes finds a stronger one from the same location.
No solution, other than to move!
I didn't experience any of this with my, now, old Nexus 5x, so I'd say that mobile coverage is unlikely to be the cause.

I also get either 0% or 0.1% overnight drain as well. But what are you looking at in BBS? I usually look at partial wakelocks and alarms. Next time that happens take a look. Once on my Pixel I lost that amount and as it turns out a news app was running a video all night long. I sincerely doubt it's a defective battery but rather a rogue app and that's why a reboot fixes it. Push comes to shove you will have to head over to the BBS forum and post a log file. There are instructions in the OP.
