So, generally, just about everyone say wifi off is best to save battery life.. How so? With wifi on (while connected to a connection), your phone doesn't have to strain itself using 1x or 3g or any of that but simply uses the wifi smoothly with ease.. I personally tend to get much better battery life with my wifi on due to all the Facebook and xda and Web browsing I do..
Is it just me or does wifi seem to keep power drain lower?
I stay connected to wifi while at work and home and I think I get great battery life. Today at work our wifi was down so I had to connect using 3G. My battery dropped 5% in 30 min with the phone just sitting in standby. So yeah I think it is better using wifi.

Basically if you are Wi-Fi Connected it will save you battery, but if you aren't connected to any network it will drain your battery looking for one.

I've noticed that if I leave my phone in an room that has a weak wifi signal, my current use is always around -100mA a minute whereas when I have a strong signal it is only -6mA. I have tried multiple 2.3 roms and they all have the same behaviour (haven't had time to try 2.2). Is there any way to just drop the connection when it's weak? I've noticed it happen by itself sometimes but it stays with the weak connection for long enough to cause significant battery drain. I tried looking in tasker but there is no wifi strength variable
On [ROM-AOSP GRH78C] Oxygen v2.0-RC7:
Settings > wireless connections > wifi settings > wifi policy set to "go to sleep when device sleep"
And you are done _ only 14% drain on wifi with poor signal after 10 hours powered on. Hope it helps you
My last piece of work

i've been using T-Mobile WiFi calling for a few weeks now, and for the most part battery life seems good, maybe even better than without.
However, last night it sucked 30%+ of my battery with a partial wakelock overnight without me even touching my phone. Anybody seen this before or have an idea on how to keep it from doing this?
Oddly enough, under Better Battery Stats, it's listed as AlarmScheduledService, but just to make it clear I had no alarms scheduled. Under Android's native battery usage display, it first showed up as *wakelock* before resolving into IMS Service.

Ive noticed the EXACT same thing... id go to sleep and wake up with like 40% battery missing... stopped using wifi calling problem went away :\
I got my phone on Monday and it has been working extremely well. The battery has been fine. But since yesterday (I haven't downloaded any apps) my battery has been dying really fast. I've lost 10 percent in the last 35 minutes. This is the first time cell standby is draining more than the screen. I also disabled sprint connections optimizer.
Here is a screenshot of the battery stats

Do you actually have a data connection? It's grey'd out. If you find that's probably why. Weak signal draws a lot of power
it has nothing to do with signal. my g4 lasted twice as much as this g4. i also have the sprint g4 and I'm about to just go turn this in and go get an s6 piece of junk with no removable battery or sd card slot. this g4 has worse battery than any android from metropcs.
I've had WiFi disabled for most of the day and I'm noticing something weird in my battery stats.
My battery has been draining a little faster than normal, as if Doze hasn't been activating, so I went into settings to check on things. I noticed that my stats show that my WiFi connection is enabled. I've been watching it for the past hour making sure WiFi is disabled. Battery statistics still shows that WiFi is enabled.
Has anyone else experienced this? I'm on the L build and WiFi scanning is off and WiFi active during sleep is set to only when charging.

UPDATE: I rebooted and cleared cache and it seems like the problem has stopped. Still have no clue what caused that to happen.

go to settings and search for wi-fi scanning. turn it off, you should see your issue resolved.
Go to advanced config wifi and put the wifi mode in 2.4Ghz

Click to expand...

Maybe the yellow cellular signal? I know at my job, I have to turn on airplane mode and turn on WiFi cause all the red/orange signal I get kills my battery even if I'm not turning my screen on.

If you look at the flat section just before the end of the green, that's when the device was in doze. Before that the device was not entering doze, either because it was in use or was detecting movement. But looking at the graph doze is working properly, 3 days left.. Definitely working as it should.
