Guys, tonight I decided to switch off mobile data and WiFi when I went to sleep. Now noon, when the battery was almost over I decided to analyze some attention to battery depletion statistics and realized that even turning off the WiFi it continued to appear that spent the whole night on. Also, see that shortly after I slept network operator turned yellow. How to explain? My carrier has the much more stable network overnight just by reduced use and the absence of network overload.
He had the 3g network enabled, less mobile data.
It happens to me too. I guess it's only a visual issue, I dont think wifi is draining battery life.
Due to Wi-Fi scanning always available. Its actually keeping the Wi-Fi on if that option is chosen in Wi-Fi advanced options. Turn that off and you'll see that your Wi-Fi actually shuts off.
Tons of threads throughout the forums (S6 and others) regarding the battery impact of keeping WIFI on during sleep. Some suggest that keeping it on always actually results in the least battery impact while others suggest that never keeping it on is the best battery bet (at the expense of increased data usage).
Take the poll and let us know which side of the 'WIFI always on' fence you stand and feel free to comment below on your individual observations between this setting and battery life.
For me, before coming to the S6E, I've always "always kept WIFI connected during sleep" but since coming here (from an S5) and dealing with the dreaded cell standby issue and battery drain, I've been keeping it "on only when plugged in". It seems to be having a positive impact on battery life, although I've done a few other things at the same time to combat the drain issue: shut off Samsung Email App syncing, froze Amazon and a few others, etc.
Under WIFI > More > Advanced > Keep WIFI On During Sleep . . . which radio button did you select?
WiFi toggling really hasn't mattered in years. Location is what will get you as we have tons of apps these days that will do background location polls. Tinder, Uber, and many others will destroy it if you don't completely quit the apps. Google services also has it's own fair share of draining battery life with location on.
For sometimes MI 5 battery was acting a bit weird time to time.
Clean flashing to LOS seemed to solve the battery issue, but I discovered another issue while checking up with ampere.
When wifi is on, battery drain is abnormally high. (-870 ma on average in ampere). Even in idle time, there can be 20-30% drain when the phone is virtually nothing. And in addition to that, the heating was a bit high too, with wifi on.
I tried everything I could to solve these. Tested different roms (Xiaomi.eu, LOS, RR, Paranoid), firmwares, tried wavelock blocking and all that.
Of course, I tested the battery drain on a fresh rom - and the issue persisted. So it's not some rouge 3rd party app, unless one of the Gapps is the culprit. But, of course, I even tried disabling some of the gapps like gp service and play store, just to be sure. Yes, the problem exists even with synch and location off, and those wifi scanning and other settings doesn't do anything either.
However, with wifi off, battery was quite good (-100 ma drain on average in ampere)
Recently the issue started escalating. Not only was there the abnormal high drain with wifi on, but toggling wifi crashed the device and started a reboot, after which the device connected.
The only major thing I had remaining to be done - is fastboot. I did even that. Fastbooted into official roms, older 6.0 Xiaomi.eu roms which worked fine in the past ....but the issue persisted. In fact it started to escalate further. More reboots when I try to switch on wifi. Sometimes got stuck in a reboot loop ...and so on.
Right now, wifi is not even connecting. It just stays at 'saved'. Oddly enough, enabling bluetooth and trying to reconnect seems to allow the connection to take place. The drain is still here. (The solutions in this thread: https://forum.xda-developers.com/mi-5/help/wifi-connectivity-problem-t3517777 isn't helping me either)
I don't think this is a router issue either. I did tweak router settings, channels, and all that. I rebooted it and all. No help. And, other devices are working fine with the same router. But, the most definitive evidence that it's not a router problem is that I faced the same issues when trying to connect (with wifi) to a hotspot created from a mobile network from another device.
Do you think it's the worst case scenario: a hardware malfunction?

Could you provide battery apps and hardware usage stats and graph?
My prediction it caused by Google location service that try to lock location but was unable to get GPS lock, so it tried to used WIFI scanning to get location lock.
Try to disable WiFi and Bluetooth scanning option on Location - Tri dot menu on top right - scanning

I can provide the stats later. My device has been offline (normal condition) for quite a while...so there's not much stat to share as of now. I will collect and share them later.
However, I have checked them before. There wasn't anything too interesting. The graph very vividly showed how it fell only when wifi is on...but other than that, most battery was taken by device, idle state or something like that. I didn't find anything interesting in betterbatterystats either. Other than that I did checked the frequencies with kernel auditor too. It seemed normal overall. Though once, I did notice high spike in CPU usage. IIRC, the phone was in deep sleep for most of the time too. Not sure, what the current state is, because new issues are coming up now. So I have to recheck the condition.
I always keep wifi scanning, bluetooth scanning off anyway. So that's not the issue. 'I will again check in the china rom (no gapps), this time more rigorously,....that should clear gapps out of suspicion, if they are innocent.

Check the screenshot
In a freshly fastbooted MIUI global stable rom (with wifi scanning off, and wifi always on off), I got 1% battery drain (100% -> 99%) overnight (6 hours approx)
But, only in a few minutes battery went down to 91% when wifi was on.
The device was idle in both cases.
In past I have assured that it was in deep sleep. Similar rate drain in chinese rom (so no rouge Gapps), and same drain in custom roms.
The hardware usage was taken after I used the device for a while, which is why drain due to screen on is high. Anyway, even before using the device, the maximum drainage was attributed to 'idle phone' so there isn't really any interesting info. One thing to note, that the hardware battery drain states doesn't consider wifi to be the cause of high drain, however the drain is still clearly correlated with active wifi.
Just received this phone and enjoying it so far however, I've noticed on WiFi that I've set it to Never under keep WiFi on during in sleep, but when I leave it overnight and check battery stats the WiFi chart is telling me it's been on?! Also seems like at my home WiFi the standby drain is more then elsewhere I've been staying? Is there a setting on my WiFi I would be aware of?
Thanks
Setting - security & privacy - location services.
Tap the 3 dots upper right corner.
Tab scan settings.
Make sure Wifi-scanning is disabled.
That's off, it must be related to my router if it didn't drain at a friend's house over night, not sure what though!
I got my S10e exynos a little over a week ago and gave it some good weekday battery life testing throughout the this past work week.
The screenshot is after a day of work, with the vast majority of the time on LTE and noticing massive WiFi drain. I've noticed that WiFi drains between 25-45% no matter if I'm using WiFi the majority of the time or not. Compared to my Pixel 3 that drains 5-10% from WiFi.
Anyone else getting WiFi drain? Could someone with a S10e SD855 post some battery stats? Please use gsam if possible.
Is your WiFi scanning turned on?

Hard to determine which of these options would be considered "WiFi scanning", but they're all off except LTE switch over.
Just search wifi scanning and Bluetooth scanning
Biometrics and security, location, improve accuracy, turn off wifi / bluetooth scanning.
connections, wifi, advanced, I disabled the "switch to mobile data" to get better battery
Yes I am having this issue as well on my S10+ US Unlocked version. 1.5 hours of screen on time draining 5%, WIFI draining 8%. Doesn't make any sense. All o fmy WIFI scanning and auto switching is turned off.
Someone said it is because the phone doesn't go back to sleep on Exynos models after you've received a phone call
A reboot fixes it until your next phone call
Patch should fix it
Reboot doesn't fix it for me. I also have had two different s10s so it is definitely something software related. It drains so Mich that I keep wifi off unless I absolutely need it.
