So I have a Verizon LG V20, un rooted, completely stock. I noticed a few months ago that randomly I would not get notifications when the phone was asleep (screen off) while on wifi.
If I was on cellular data, notifications were great.
But when I was home and the phone was connected to wifi, and left alone on my counter, it would be silent until I wake the screen.
Then it's 15 notifications all of a sudden from 10 min to hours ago.
I have wifi always on checked in advanced wifi, notifications always on the lock screen selected in apps.
This only affects the phone in wifi.
But now, after Oreo, it seems to be happening ALL the time.
Anyone know what's going on?
I'm connected 100% of the time to my 5ghz network.
Is this a 5ghz vz 2.4 thing, or a wifi thing.
Any ideas?
Is Verizon screwing with me to get me to keep my cell data on always?
Any help is appreciated?
my only problem was with the battery saving modes, once excluded from the list my notifications worked as expected

okay--i've been struggling with this all week and I can't figure out what is doing this. It might be bluetooth but it could be something else.
As I understand it Wifi should turn off when I put the phone in standby. For the first half of today that was the case. then mysteriously, it stopped turning off and guess what, my battery usage disappeared.
I have checked my BsB tweak settings, it is not set to have wifi on in standby. I have checked my wireless connections to disconnect after 30 seconds. Although that probably only works if i am away from a wifi signal all together.
so what else do i need to do to switch it back to default--I don't want wifi on when it's on standby. At the least, i want to be able to toggle it like it's supposed to.
thanks for the help. Once i get this figured out I am pretty confident my battery usage will be good.
Something very curious has happened the last week or so.
The Wifi stays on, even when the phone is in sleep mode. It is evident when I unlock, the wifi symbol on the status bar doesn't bleep (reconnecting), but stays solid (connected). Of course that could be an operating system displaying error, but it's not; functionality is there, wifi stays on, device connected to the internet. And I'm not talking about the short amount of time that the wifi stays on after locking the phone. I'm talking I'm receiving notification etc as if I was using data.
I noticed it when, after waking up in the morning, I realised a massive battery drop (from 65% to 27%) overnight, although I keep my phone on airplane mode at nights.
As I haven't recently used any mods, regedits etc, and I haven't updated or flashed any rom (btw I'm on debranded stock 8107, with KK2), I can attribute this weird but very interesting behaviour to 2 possible things:
a. I installed some app, possibly homebrew, that somehow (even the dev didn't know about that) keeps running keeping wifi awake under lockscreen
b. Maybe it's because I'm on Airplane mode. I kept on being on Airplane mode from the moment I noticed it (as I have input my SIM to another phone). I should note though that there is a sim in the phone, I'm just on Airplane mode. Is that a known feature? Wifi stayin on under lockscreen on Airplane mode? I don't think so, as I would have noticed all that time (I keep my phone on that mode a lot).
That behaviour has persisted after soft-resets (reboots) and battery charges. The only hardware change I made the last week was using a non OEM replacement battery (the ones that reboot the phone when connected to the charger). But I'm using the original battery.
I should note it consumes about 4% of battery life for every hour, quite viable.
thats weird, but to some ppl, like me, i'd be happy if this happens, would love wifi staying on in sleep mode.
but, the opposite happens with mostly everyone
Even more curious thing that I found out today. When the phone is SWITCHED OFF, and wifi was on before switching the phone off, I have battery drop (almost the same as if being switched on with wifi on, around 3-4% per hour, in my instance from 43% went to 11% when I switched the phone on).
I don't know if the (original) battery has been messed up, so the battery index is not reliable (the reason I bought replacements was that in a span of 1 month, I was not treating it right, a lot of charging, heavy operation simultaneously, resulting in excess battery heating etc), or for some reason the use of the fake battery messed up the software part (both battery metering and WiFi stayin on)
I'll do so more testing and I'll report. Has anyone tried to go to Airplane mode and switch on Wifi, to check if it stays on under lockscreen?
It stopped today... weird!
... And it happened again, this time I think it might have been triggered by Audible, I might make a video as a proof.
EDIT: I was making that video, and realized on cam that it stopped happenning, and then I realized I had flashed beforehand the KK4 firmware. What a douche! If it happens I'll try to capture it on camera
When the data connection is OFF (like when you activate airplane mode) wifi remains connected even when you lock the phone.

No that doesn't normally happens, unless you have an app running under lockscreen and using WiFi (like a music streaming app)
So, after no problems for 3 months, my stock AT&T S4 has suddenly started with some odd behavior where wifi is unresponsive for 30 to 60 seconds immediately after every time I wake it up. Then wifi works normally.
The wifi connection icon stays on during this, and I see it trying to upload and download.
When the phone is asleep, it syncs appropriately over Wifi and I get all of my notifications.
This happens on all wifi connections. 3G/4G is unaffected.
I have wifi sleep disabled in the wifi Advanced menu.
Any guesses as to what might be causing this?
I've noticed for the past few days that when i look at my phone in the morning, the wifi is disabled (greyed out). I usually leave the phone on streaming spotify while charging. I can't remember off the top of my head whether this happened when I first had it but I definitely know it has been doing this for the past week. I'm using the Canadian version of the Samsung 7 Edge. Has anyone else noticed this behavior? Any advice would be appreciated since i'm trying to figure out whether this is a software bug or whether something is wrong with my wifi chip. Thanks in advance.
5GHz
I Had similar issues it was because i was connected to 5GHz on my Asus router, I had constant disconnects the the wifi icon was greyed out. I had to switch to 2.4GHz and everything is working smooth. Don't know if it's just me having issues with 5GHz.
At work, I have it connected to 5Ghz for at least 8 hrs a day and leave it on streaming music and wifi never disables itself. I tested the phone last night again but instead of having it plugged in, i just left it on battery, connected to wifi and streaming music. This morning when I woke up, wifi was still on and connected. I've come to a possible conclusion that in my specific case, it could be the fact that it is getting too hot while charging so it turns off the service perhaps ? Does anyone know whether this is a normal behavior ?
Do you have Keep Wifi on during sleep turned off?

That option is most definitely have that option on. I suppose it could be the router I'm using as it is also an Asus model but that a bit of a stretch. I have since factory resetted it and the issue still persists.
Can someone confirm if this issue exists on their device?
I live in an area with no cell service so I put my device in airplane mode and use WiFi Calling. This worked great for my OnePlus 5T. Now with my 6T I get very heavy battery drain when I do the same. Somewhere between 2 and 4 percent an hour. If I have good cell reception and airplane mode off I don't get any standby drain, like it should be. I have attached a screenshot of the drain while my phone was in standby. The red boxes highlight when it was in airplane mode with WiFi Calling.
I would like to figure out if it is just my device with the issue or if everyone is affected. I am on MetroPCS if that makes any difference.
Trying to figure out if this has to do with Magisk, or maybe my DTIM and Beacon intervals I set in my router. No apps are holding wakelocks, phone is active less than 5% when screen off. I will factory reset if a few people state that they do not have this issue.
Can someone reproduce these steps and let me know if you get heavy standby drain?
1. Enable WiFi Calling.
2. Turn airplane mode on.
3. Turn WiFi back on.
4. Make sure you are connected to WiFi Calling.
5. Check current battery level.
6. Turn screen off and leave phone for an hour or more.
7. Check to see if battery went down more than 1%.
Thank you!
In case anyone else has this issue it seems that the heavy drain was due to a DTIM interval of 50 that I had set on my access point. Setting it back to the default of 1 seems to have stopped the heavy standby drain.
I was thinking of buying a OP6T and using WiFi calling as I have no cell/4G coverage at home to try and avoid standby drain issues I have had with previous android phones. Stupid question, why do you need to enable aeroplane mode? Does the phone not switch automatically to WiFi calling when it finds no cell signal like iPhones do? Surely forgetting to turn off aeroplane mode causes problems. What are your experiences in general with WiFi calling on this phone? What sort of battery drain are you looking at overnight using WiFi calling? Do you have any other tips for minimising standby drain when you have no cell coverage?

I enable airplane mode to prevent the phone from draining looking for cell service that it will never find. It will automatically switch to WiFi-calling but it will still constantly scan for cell signal just wasting battery, all phones operate like this.
Wi-Fi calling works great for this phone. The only issue I have is that MMS for T-Mobile/MetroPCS does not work. Calling and SMS work 100%.
I usually loose between one and three percent batter overnight (about six to eight hours) with airplane mode on with Wi-Fi on and Wi-Fi calling connected.
To minimize standby drain with no cell service just put your phone in airplane mode and then turn Wi-Fi back on so that Wi-Fi calling connects. This tip would work with pretty much every phone.
I hope this helped!
Thanks for the information. Did WiFi calling work automatically on your phone or did you have to contact your airtime carrier to set it up? Can you please confirm that with aeroplane mode on you can make/receive phone calls and send/receive sms messages. I need to stay in touch and have good battery life, not one at the cost of the other. I don’t really send mms messages so that is not a problem. What is the DTIM interval you mention on your router/AP and how does this affect the phone? I will be choosing between OPT6 and the P20 Pro and I am concerned about brightness levels on OPT6 as screen seems very dim. I understand google has made changes to the brightness slider in android Pie but I had to have the brightness at 100% where normally it would be at about 50-60% on other phones. Is this something you find a problem or does the adaptive brightness learn your habits?

WiFi calling worked right away with my phone provider, MetroPCS. All I had to do was use their app to set my E911 number for emergency purposes, I am in the US by the way. Some carriers may have to contact their support to enable the feature for your account, I cannot say for any other carriers than MetroPCS.
I can confirmed that airplane mode with Wi-Fi calling works 100% for calling and SMS. The MMS issue seems to just be an issue with the US carriers T-Mobile and MetroPCS from what I have seen. Just make sure you turn Wi-Fi back on after enabling airplane mode.
You can look up what the DTIM interval is on Google if you are interested in it. Basically its how often the router will include a message to wake up the Wi-Fi on your phone to process messages. I had mine set to 50 or 100 beacon intervals and that was causing high standby drain. Pretty much every router defaults that setting to one so you shouldn't have to worry about that. I currently have mine set to three with no issues.
As for the brightness slider it works great for me. I think it's a little on the right side most of the time, some people say it's too dark sometimes, it's all subjective to the person and how they use their phone. Personally I think the new brightness slider is a huge improvement over the old versions. You have a lot more control of the brightness at lower levels so you are able to better set your phone in low light environments. Also the screen gets plenty bright at 100%. I have not had issues using my phone outdoors in bright sunlight. As for learning your habits with the brightness, it does seem to do that to some extent but don't expect it to be magically right all the time.
Thanks very much for all your help. Have a great New Year.
