I know this was an issue an issue in the past for older phones. With the recent high tech phone/smartphones/battery, I am just wondering if this is still an issue today.
The reason I am asking, I experimented and let my HD7 stand still without using it with the wi-fi on then and wi-fi off for almost a day for both and appears that I have the same battery remaining. I wish I could see the percentage use but looking at the icon itself appears the same to me.
Any other thoughts?
So, a pretty nifty thing about this phone/OS, is when the screen turns off, it automatically kills the WiFi. When you turn it back on, it connects again.
This is how they're able to conserve battery life. The only downside, is if you were downloading say a big game, via WiFi, and the screen times out, WiFi dies and so does your download unfortunately. I was able to get the download to resume once, but usually not.

i think wifi doesnt consume any battery at all when its "just connected", only when a upload or download is going on , you might find the difference...

No, you are wrong. Even stay disconnect, the Wifi Module will keep searching for the new wifi spot and it kills the battery a lot. Than why i usually switch my Wifi Off (both my HD7 and my old HD2) when i am not going to use it
For the first time with a smartphone I've been leaving the Wifi on all the time, since it doesnt seem to really impact the battery that much. I'd only turn it off if I know I'm going to be a day or two out of Wifi coverage, just to save me having to grab a charger.
With my TD2, having Wifi on all the time not only shagged the battery but also slowed down the UI and made the phone hot as hell.
With Android I would have to keep my Wifi off because it would kill my battery but on my HD7 I leave my Wifi AND bluetooth on all day and I still get pretty good battery life. I only charge once at the end of the day.
the wireless radios, bluetooth & wifi, are so much more polished and refined as compared to the those in WM5/6. With WM, used to flash new radios posted on xda to acheive better reception/power consumption performance. WP7 does it right out of the box...
btw, you can set 'notify when new networks found' to off. If not needed by you, probably save some juice.

I believe the only thing that changes is that it doesn't tell you when it finds new networks, but it's still always on and searching. So it shouldn't make much of a battery difference on or off.
That being said, this is the first phone where I have left Wi-Fi on at all times and I get awesome battery life. Actually, my battery period has just been great. No complaints about how long the phone lasts. Much more than any Android or Windows Mobile phones I've used in the past.
Hey everyone.
The battery life on my Ace without using data is brilliant. Even using wifi and playing games etc it can last around 2 days.
When data is turned on I can see the battery % counting down when I use Facebook or use the web browser.
This has happened on a number of ROMs I've tried, even stock based ROMs. I tend to use either on demand or smartass cpu settings.
I'm currently using Democracy 3.2 and it's having the same problems.
Has anyone else experienced this or found a way to fix it?

Some apps that have internet permissions connect every now and then. With data on, battery will drain:
-when transferring data
-when switching edge, 3g and h
-when establishing data connection if it is ever lost.
If you got lots of apps transferring data, it can be solved by installing a firewall on a rooted phone (like droidwall).
The other thing is bad network coverage, which cannot be solved (switching too often or reestablishing data connection frecuently).
Edit: either way, data is a major battery hog when actively browsing (facebook, talpatalk, browser)
If using wifi isn't an option, some users report better battery life using 2g only
I don't think 2G would be an option for me... I've tried it before and the load speeds are far too slow for a lot of my apps to be usable.
I have noticed that the battery drains a lot when trying to establish H/2G/3G connection. I usually just turn data on only when I need it. Do you think it would be better for the battery to leave data on all day so it doesn't have to reconnect when I ask it to 10 times a day?
It seems to be the Facebook app that drains it most. Email / XDA / Dolphin doesn't impact battery quite as much.

Constantly switching data on/off drains more battery than leaving it on all day cuz it will only use battery when transferring data, and if you're on wifi, wifi has preference.
The switching and establishing of data connection drains more battery than the screen at max brightness.

Wow... That sucks... Is that just for Ace's? My girlfriends HTC Sensation doesn't seem to be affected by switching data on/off a few dozen times a day.
I'll give it a try today. Data is on all day and I'll see if I can squeeze a bit more juice out of it. I've also installed droidwall so that everything gets wifi access but only the stuff I use gets data access.
Thanks for your suggestions, I'll let you know how it goes :victory:
I've given it a try.
Previously I'd turn data on/off when I needed it and it would use 5-10% battery establishing connection and transferring data.
With data on all day I lost 5% in the morning establishing connection but after the transferring data throughout the day impacted the battery far less. I think it really helped that I had droidwall so there wasn't anything downloading in the background that I didn't want to. I got home at night and still had around 70% battery left.
Thanks for your help and advice guys :victory:
I'm shocked, without 3G I still only manage 1 day not 2days count yourself lucky!
I have same problem
Wifi uses less battery then data

Turning data on/off a few times again I'd get about a day if I was lucky.
My phone has been on for a little over 24 hours with data on and it's on 80% right now... I've only really used 3G a couple of times but I'm not a particularly heavy user. It spends a lot of it's time locked and a asleep.
Has anyone else had this problem? since upgrading to a 4.3 sense based rom (tried 3 different roms), my battery life has become horrible..i can barely get 2 hours of screen on time whereas i used to get 4+ on 4.2.2 roms.
i know alot of people have said that 4.3 improves battery, but it hasnt for me, its done the opposite.
also has anyone noticed strange heating up of the device? for example in asphalt 8 the device thats slightly hot and then cools down while playing. but in games like candy crush or zynga poker the device continuously gets hotter and hotter..
tips/fixes/stories anyone?
Mine has been really good. Like, 3-4 hours screen time good. When I'm on wifi (N only, G wifi drains a lot) my battery percent just flatlines on the graph until I pick up the phone again. Sounds like a rogue app since I don't have this issue. I run ARHD 20.1.

did you upgrade your firmware to 4.3 ( 3.09.401.1 ) also ?
met few guys who had the same problem and upgrading FW helped.
good luck

I'm running arhd 20.1 aswell. And I would LOVE to see that happen again, my battery drains around 10% overnight, and I'm a really late sleeper, so that means in 5 hours it's lost 10% on standby..and it's weird cause WiFi shuts off after about two hours,so I know that's not causing the problem.
App usage shows android system as the app using the most battery. When I check in the morning it shows android system and kernel to be the top two users.
Could it be a radio problem? I've seen a decrease in signal since ive upgraded to the 4A.17 radio from firmware 2.24.
I'm thinking about flashing the minsense Rom or even a ge rom and see if that helps the problem.
It doesn't seem to be a rogue app cause I actually have less apps then I did on 4.2.2, and none that are new..

I'm still running the current T-Mobile firmware, not 3.x. (I'm still S-ON with hboot 1.44) Thought that was worth noting.
Have you tried putting the phone on WCDMA/GSM auto instead? If your LTE signal is weak (or any kind of signal is weak in general) I see this phone's battery life usually take a nose dive. It has so far from my testing saved me a ton of battery to switch the phone manually into GSM only when I'm inside a building at work to get more bars, then switch back to LTE auto when I leave. Try leaving it on overnight on different radio settings, and with and without wifi. It could be a cell radio drain. And btw get GSAM battery monitor, the stock stats don't seem right to me. Android System being high in the HTC battery stats tells you nothing really from what I'm seeing so far.

the funny thing is i dont have data, since i get wifi wherever i am. i also think its a radio problem though, my gsm signal never seems to be full, and people constantly tell me on the phone that they cant hear me. so what im doing (right now) is flashing a ge rom, specifically sinless rom, then im going to flash the new ge radio, 4A.18, and see how that plays out, prolly going to flash a 4.3 kernel aswell so i can uc to 162mhz or whatever the value is.
i seriously believe its the radio+lack of kernel on 4.3 sense roms that are causing this problem for me. so once this is all done ill test it for the rest of the day and see how it goes. thanks so much for your help

If you don't use any apps, of course system uses the most.
You need to check for wakelocks. If you have unexpected battery drain, it's likely that the phone is not sleeping properly, i.e., being kept awake. Betterbatterystats, gsam, wakelock detector etc.
What was the change in signal attenuation, or are you just saying the the display bars are different?

i use apps, just nothing new compared to when i was on 4.2.2.
and no wakelocks according to gsam, i lost 20% overnight (7 hours)
i dont get what it is. i upgraded the radio to 4.19 now, but for the signal issues, it included lower bars, bad audio in calls, and random loss of wifi.
i removed basically every app, besides some essentials like facebook, whatsapp, and a few others.
i tried switching to an ge rom, but i just cant stay on it for too long, vanilla android is so plain compared to sense.
so the last thing i can think of, is a rom known for its battery life. not asking for a comparison, just your opinion in which rom gives the best battery on 4.3. any suggestions?

Charge your phone up all the way, put it in airplane mode, and unplug it for an hour then don't touch it. Then post your battery percentage. If it isn't still 100 or 99 then you have a more severe problem that actually relates to the battery itself.

Show us a graph of your signal strength from GSAM, and show us a screenshot with how many bars you have. At least you know now that the battery is definitely not shot. It is probably mobile data related...hmm did you ever try letting the phone sit with mobile data disabled as well? It should drain almost as minimally as airplane mode.

So wait, your signal is really good but your phone drains like crazy, and while you're on WiFi? Okay, what wifi router are you using and is it G or N and is it dual band?

its absurd i know..its already down to 93% with 9 minutes screen on..
and its a dual band router, im normally connected to the 2.4ghz band, and its with wireless ac, which the one supports. Which is weird cause i thought ac improved battery life..
edit: im an idiot, wireless ac only works on 5ghz bands, but that still doesnt explain the drain on wireless n..as my previous router was also wireless n

Have you tried 5 ghz N by forcing the router or your phone to operate only at N speed? I use a TP-Link dual band N router and I remember seeing s drain of about 4 percent overnight for 8 hours of full idle with full sync.
I have tried with both 2.4ghz n and 5.2ghz ac, same problem persists
Awake is 3x screen on, I don't think that's normal, somethings keeping the phone awake much longer

so ive done a bunch of other tests, and i can confirm its wifi thats causing this massive drain, not wakelocks, not roms, or anything else.
when the phone is left with wifi on, but not being connected to any network, battery drain is minimal overnight.
its the same on both 2.4ghz and 5ghz bands, so it this a router problem? if so, do you know any tips that could fix it?
Do you have "Best wifi performance" checked? That seems to eat battery.

i have no option for best wifi performance, just "wifi optimization". i found the problem, it has something to do with my new router and its bad compatibility with android devices. the phone seems to be awake 2x the screen on time and the main culprit is "wlan_rx_wake" wakelock
I've found several threads about drain, but all of them are Android 5 related.
Unfortunately I still have this problem on Marshmallow.
I don't notice it when using the phone, but while idle, it drains battery. Attaching the screenshot indicating I charged my phone at around 10 pm and at 1 pm next day it was already at 15%. Screen on time was only 2 hours.
Wakelock Detector does not work on Marshmallow. Installed BetterBattery Stats to try to find out what's causing this, but If any body's experienced it and has any idea what should I do, please share your opinion.
I've got MRA58R, bootloader unlocked, rooted, root aps list is: call recorder, adaway, betterbattery stats, es file explorer, gmd gesture control, nexus 6 double tap to wake.
Don't know if any of this is really important, but still. The rest is pure stock installed with full wipe.
PROBLEM SOLVED:
Nexus 6 on Android 6 has bug with 5 Ghz WiFi networks, use 2.4 Ghz and your battery will be fine!
Today before going to sleep I charged the phone to 100%.
I left it with wifi on for the night. In the morning after 8 hours I had 65% left. Screen on time was only 42 mins.
Attaching screens from battery and better battery stats.
What should I do next?
I would appreciate any opinion.
I wanted to try turning off Google Now (it helped my friend on Nexus 4), but on Nexus 6 I just can't find this ON\OFF switch of Google Now, how to turn it off?
I'm running pure nexus and get none of that. Around 6 hours sot. I'm not sure what would cause this, have not seen it

This. I had a similar issue a while back (although it didn't happen every time). One thing someone told me was to avoid the 5g band on wifi. Whoever it was correctly determined that I was connected to the 5g band of wifi at home and suggested I use it on the 2.4 instead. I did so and my drain dropped significantly. Now if I charge to full, leave it on my nightstand overnight off charge, I wake up 6 or 7 hours later and lose *maybe* 1% per hour. That's with wifi, bluetooth, gps all on etc.

I'll keep my fingers crossed for you that this fixes the issue. Additionally I should have noted, the person who suggested I use the 2.4 band instead of the 5 specifically noted that there is a documented "bug" where 5g wifi bands cause significant drain. That's apparently the reason that 5g specifically tends to be the culprit.

When you set it up did you set it to allow it to keep wifi scanning even when it is off for the location settings? I leave my wifi on 99% of the time and my battery life is great.

I dont remember if I did but I did turn that setting off when I was trying to diagnose the issue. I don't know if maybe it's a 6.0 bug that needs to be fixed. Good thing that being a nexus I hope it won't take too long.
I updated the firmware on my router and after doing thus none of my devices would enter power save mode on the 5ghz radio anymore and drain is now massive (check your router logs)
I tried flashing back to the prior firmware but still no go, so it must have been a driver update on the Quantanna radio as that's the only thing that was updated and it's a known issue with my particular model.
That helped me! Thank you guys! I connected to 2.4 Ghz and lost only 6% overnight!
I wish this information was easier to find, I'll update first post when I get home, it'll probably be useful to a lot of people.

It is a known issue with Quantenna radios on multiple routers; my ASUS RT-AC87 is one of them. Specifically as you said, on the 5GHz band. Switching to 2.4GHz wireless can fix this for the time being on Quantenna-based routers.
I've also had times where my battery seemed to have excessive drain if the cell signal dropped to non-existent; the N6 appears to drain fairly quickly searching for a signal. Unfortunately, AT&T occasionally drops in my house, and that's the carrier my work is on, so I have to live with it.
Hey guys, I am running stock 4.0.3 rooted with supersu and using the latest franco kernel. I am getting massive drains even while using the phone on wifi and keeping it on standby, while connected to wifi. Getting drains about 3.3-4% per hour on standby on wifi. This is absolutely crazy. I tried some older suggestions mentioned here https://forum.xda-developers.com/showpost.php?p=62074306&postcount=118 . But even that doesn't work. Battery drain is normal on mobile data, but when connected to wifi it absolutely goes crazy. Can anyone provide any insight? There are no rogue apps, I have been checking through better battery , wld , accu battery, etc.
You've probably already turned it off, but I'll just point it out in the rare instance, but make sure scanning is off. However, I did notice that you said it is when wifi is on and your phone is sleeping when you get that drain. A fix is to go into wifi settings and under "Keep Wi-fi on during sleep", pick the only plugged in option. Ideally, you should get to the bottom of this issue, but if you don't have the time and no one else figures it out, this may help.
EDIT: I wonder if smart wifi switcher has anything to do with it? Wifi connectivity fluctuates and if you have two connections that have very similar signal strength, would your phone constantly switch between the two networks in a futile manner? If this does happen, I can see that draining your battery significantly, but this is based on the premise that the switcher does not have some type of buffer zone where it does not switch if the difference is negligible.

Yep, I always keep scanning off! And i did try with that suggestion too, I changed the setting to never and it still drained battery. Wifi stayed on for sometime even though i set it to never and then finally turns off after a period of time, but i think that could potentially drain more battery? Are you using wifi all the time? What are your stats?
I have all those settings turned off, smart switcher, ipv6, scanning, etc

Last thing I can think of is trying to use stock kernel to see if it is FK that is the culprit. FK shouldn't be the issue, but perhaps something screwed up during the flashing process? Now I'm essentially just asking you to do trial and error

Nah man, I trust FK more than stock
I have had similar issues with stock as well.
What are your battery statistics?

Note that I'm in Beta 3 and running its stock kernel so I don't really see the usefulness of giving my battery stats, but yes, battery life for me has been good and unaffected by wifi draining.

Whoa, how the hell do you even get 2 hours 17 mins sot with 85% still remaining?
Is it really just me suffering from this wifi drain bug?

It's most likely not just you, but based on my perusal of the 3T forums (especially on the FK thread because that's most relevant to how you set up your phone), not many people are facing this issue. Does betterbattery stats not show anything funky or out of the ordinary? Can you post a screenshot of your betterybattery stats including the kernel wakelocks, alarms, and partial wakelocks page?

Check these out. I am totally fed up. I think I might have a faulty unit.
Getting 4% drain on standby!

I'm beginning to think it's not wifi, but the app Saavn. It may act differently when on wifi vs on cellular data and remain active constantly when on wifi. I google searched the app and its potential of being poorly optimized app, and there are reports of it never turning off and running in the background. If that is the case, it should be showing up on BBS as more of a drain, but for some reason it isn't. Still, try uninstalling the app and see what happens.
In the end, if this doesn't solve the issue, I'm beginning to think a factory reset maybe in order. I wish you also gave me BBS alarm wakeups page because that would help see if Saavn is constantly firing off alarms or not.
Go to your "Location settings" and into the 3 dot menu in upper right. Turn everything off.
do you have wifi calling on? turn it off and see

Where exactly is the setting to turn it off?

I don't have any option to turn off wifi calling in there. I am running the beta 7.1.1 now though. But the problem still persists. Too much drain when using wifi, it's being shown as android system drain. I've seen many people reporting it, so it's not just me. But for the life of me, I can't figure out what's causing it!
Issue resolved with latest 4.1.0 and some usage pattern changes. Mod, please close the thread. Thank you!
