Battery drain on standby

Guys the battery on my s6 edge has been draining just by sitting here. Anyone else having this issue?

Yeah I've been seeing some serious battery drain. Way more than I'd expect with the battery size. Not sure what's going on.

Turning on your Wifi will kill your battery. I've had to restart my phone to make it stop sometimes. Makes me wonder if this is why the nexus skipped 5.0.2.

That may very well be the reason why nexus skipped it. Juding by the previous samsung record, it will be a while till we get 5.1

Did you have Wifi on at any point since your last restart? I've had to reboot the device to fix it.

Try turning off volte. That seems to help.

This is what i hate so much... you pay ridiculous amount of money to buy a "Smartphone" but then you have to turn all these features of to make it work efficiently.

I'm sure it's just a software bug on T-Mobile, but I was able to fix my issue by turning off WiFi, completely charging the phone, and restarting. WiFi is what causes it, not sure why though.

Where do I find Votle toggle option?

Go to settings and search for "Phone" from there you can get into call settings.

google services for me is using the most battery, which doesn't make sense.

Did you also disable the "wifi during sleep" that is used even if wifi is off? Can't remember where it is. Maybe advanced Wifi or in Location settings. Just curious. Thanks!

All you have to do is click the WiFi toggle. No other setting changes.

Gotcha. I was curious but also sort of pointing out that even with Wifi turned off, the phone will still use Wifi for location unless you specifically disable that option. It may or may not make any difference at all, but since there's a bug then it's possible that ANY use of wifi is draining more than it should (even if it's just intermittently every few minutes for location checking).

If the WiFi being used during sleep is causing any issues, the issue is small enough that it is not showing up on my battery usage page.

Well for example. I have had Wifi turned off since before unplugging my phone this morning (8 hours ago). Despite that, it has been used for 29 minutes because I didn't have that option (use wifi for location even when it's off) disabled.
Because of this, I'm disabling that location feature as well for now. I bet that's about 30 minutes my phone has been held "awake" due to this stupid bug!

If it's causing issues for you then turn it off. For me it wasn't enough of an issue to disable WiFi during sleep.

if you go to call options in the settings menu or you can go to the oem dialer and click on more in the upper right hand corner of the screen the option for it should be under setting in that drop down menu

Assuming you are on 5.0.1 Lollipop, did you factory reset after the update? Many people have experienced problems after the update but have seen factory resets correct problems.
While on the wifi settings page (the screen where you find the list of wifi networks available), touch the three dots in the upper right corner and select Advanced.
Uncheck (turn off) the option to "Always allow scanning"
You can also turn off the first option of Network notification to stop it from trying to find open networks in range.
hope this helps.

Thanks for the response,
I am on 5.0.1, I did factory reset twice, Cleaned cache multiple times
"Always allow scanning" is already turned off
Network notification is also turned off (unchecked)
Funny thing is , I put the phone in Airplane mode (wifi off too) for a while and battery graph still shows WiFi on and phone awake

The Wifi thing is a lollipop bug.
It'll always show as on even when it's off.

That bug must not hit every lollipop phone because my wifi doesn't show as on all the time. When it's off, it's off.

Weird... mine does.
Are you running any special apps (like battery savers)? What Wifi settings are you using? Is Power Saving Mode on or off?
I'm curious now. But yeah, several Note 4 users on the non-ATT Note 4 thread are reporting this issue as well and so were many Nexus users.

No battery savers or apps designed to conserve battery; power saving modes off. All I did to wifi settings was turn off scanning and notification. I have a long list of apps that I disabled since I knew for sure I wasn't going to use them. I screenshot them below if you're interested.

Ok I was wrong. My phone doesn't show wifi always on. I kept wifi off all day and it showed correctly. BUT I think it did show as always awake on the previous Lollipop update. (I'm on COC4 now).
And btw, I have all the same apps turned off as you except Samsung Push Service because it seems to not sync S Note with my Samsung account (I have a Note tablet too) and Amazon because I use it.

Update
I did some further digging , based on the amount of battery used.
1. Cerberus App was using a lot of battery, so uninstalled and re-installed it... the Constant AWAKE problem is gone
waiting a few days to make sure that problem was really gone
2. Uninstalled "LLAMA" app and now WiFi does NOT show as always on

Having the exact same issue on my galaxy s6. Just turned on clash after picking up the phone and the resolution looks like as compared to my joke Moto X (2013). It's worst when zoomed way out and fine when zoomed way in. Maggie everywhere. What the **** supercell.

According to battery screen - WIFI always on, even when turned off

Hi,
When I go to sleep, I turn off all connectivity (meaning WIFI, BT, LTE) but for some reason, the battery screen shows that WIFI was always on during the night, even though it's not showing on the list (the list where you have screen, Android OS, voice calls, etc.).
Images attached. The segment indicated between the red lines shows the night time, when the WIFI was off. You'll see that WIFI is turned on, but that's because I turned it on in the morning.
Initially I thought that it had something to do with location scanning as the same would happen on my Nexus 4 when WIFI scanning for location was on (in the advanced settings). So I found the option on my Nexus 5X (in the location screen now), and it was actually turned off. I toggled it (on and off) just in case and checked again, and of course that didn't help.
Anyone here knows what to do?
Thanks.

HTC 10 WiFi issues

So I have an HTC 10 and I generally like this device but I have a few problems though. Wondering if anyone can help me out.
1. I have extremely high battery drain while using WiFi. Like 1% every minute or two. If I go to sleep leaving the WiFi turned on I may lose 10 to 15% battery life which feels like quite a lot.
2. The battery history graph always displays WiFi as turned on no matter if I turned it on or off. It's basically a solid green line. Does anyone else have this problem or know of any solutions?
Thanks for helping!

There's a few threads about Wi-Fi issues. I have bad drain as well along with many others.
Here is a main one:
http://forum.xda-developers.com/htc-10/how-to/wifi-constant-suspend-resume-leading-to-t3392562
Check if Wi-Fi scanning is turned on in Wi-Fi setting and turn that off. It keeps Wi-Fi active even when Wi-Fi is off.

Wifi drain battery

I have a problem with wifi. In battery stats wifi has more consumption as screen.
I never seen it on any other android smartphone in my house.
Somebody with this behavior? I am using latest stock.

Check Location>Wifi Scanning

any other idea
thx, i disable scanning in location, reboot, after week still wifi 1st in battery consumption, it's not big problem, battery life on this phone is excellent, but can be better

It's a wrong report from Android, your WiFi is not draining your battery (a few of us have the same problem, me included). I don't know where it comes from but you can just ignore it (there's no real way to fix the issue I'm afraid)

Mine was doing the same - and I use Chrome a lot for web surfing
Disable Location permissions in Chrome (Settings->Apps->Chrome->Permissions->Location Off)

ok, i just ignoring it, not big deal, battery life is fine, i just was wondering if can be even better everybody know android is quite tricky

Some screenshots would be great, so people can help.

That's the kind of problem he is having, which is just a bug from Android ?

I hope you have your WiFi scanning and WiFi network notification off.
I faced same problem in the starting.
I switched above settings off and cleared cache and then switched off WiFi and restated phone.
Now it is gone. Hope it helps.

Are you guys only seeing this reporting when wifi is on but not connected? Or all the time?
Only had the device 2 days, but no sign of it for me - wifi on, background scanning and network notification also on. Only been out of wifi coverage for a few hours though.

It's when the WiFi is on (connected or not).

OK, some say it's a bug, others say it's no biggie since the large battery, but.... I used to get home after a 12 hr days work, and have 4-5 hrs sot and still 20-30% left. Now I need to keep the phone charged, because it's down to 10 % halfway... That IS a BIGGIE.... And for those who say it's just a stats thingie, well, if this thingie shows 0%: your phone WILL shut down!
Ive tried ALL tips, NOTHING works. Period. What bugs me most is that I don't know why! I turned off scanning, cleared cache, reboot, etc, heck, I even did multiple factory resets, NO GO on any of those!
Believe me I'm happy for those that have solved the issue, but this should have never happened.
After consulting Motorola's customer services I was advised to send it back for repair, and so I did. I need to get it back still, but if this really is a bug, than:
SHAME ON YOU MOTOROLA/LENOVO.
You need to fix this asap, because it really IS a BIGGIE!

Even when it was disabled all the time.

you have to disable location scanning for bluetooth and wifi. I've had the same issue. I also dont use high accuracy location. I use device only to save battery and prevent wifi from turning on. It drains crap ton of battery.

Yea! I had also disabled it and made one thread for this so let other knows the solution.
