As a power saving method, Windows Phone puts a connected Wi-Fi connection on standby when the phone is locked for more than a minute, so when you unlock your WP, it attempts to reconnect. The phone automatically reconnects and disconnects while its locked to check for notifications like email every 5-10 minutes or so. This reconnection for many is hit or miss, sometimes requiring you to go into settings to manually connect to Wi-Fi again. The only way to keep Wi-Fi connected is to connect the phone to a PC or wall outlet to charge.
Now, for some reason, a couple of weeks ago, the Wi-Fi on my Lumia 900 stayed connected even if the phone remained locked for hours and to my surprise, it had a minimal effect on battery life, I barely noticed any significant drain. It was wonderful!
Yesterday, it stopped this seemingly miraculous behavior and went back to its default power saving ways. I retraced ALL my steps and cant seem to recall doing anything specific to enable/disable this "feature".
So I was wondering if any of you experienced anything similar?
UPDATE: Its not a miracle, Skype was keeping the Wi-Fi on!
Come to think of it, I did make a Skype call just for the sake of trying out the front facing camera quality over the network.

Hello there.
I am facing a problem which i think is caused from the bt.
Everything works fine (no battery drain, no heat, not lagging, no crashing apps, perfect voice quality etc) EXCEPT when i connect my bt headset(-s).
At first it works fine, make my calls, download emails browse everything. At some point (it could be 5 minutes it could be 5hrs) i am facing disconnections with the connected bt device. The phone may or may not show it is disconnected, it may or may not enable voice through bt (but i cannot hear anything). During the call i can toggle bluetooth and speak through the phone.
Here is the chain of events.
After this it drops the connection with the wifi and the menu stays at Searching mode (i left it in search mode for >5hrs with no luck discovering any wifi). If i disalble wireless or bt or enable/disable airplane mode the menu stays grey forever and with the dots in the upper screen keep coming and coming. Long story short i cannot toggle on/off any connectivity feature (only cellular data works under any circumstances), i have to either turn off and on the phone or soft reset it. I did two hard resets (one of them was clean state) but this behavior hasn't changed.
Also if i have only bt on and connected and i leave it overnight in the morning it shows about 10 - 15% battery and quiet hours are not auto disabled (also tried to turn Cortana Off) BUT if i plug it for FIVE minutes it goes back to 90-95%. and have normal battery consumption during the day.
The only thing i havent tried (and if i do i will do it only for testing reasons) is roll back back to WP8.0.
Am i facing a warranty issue or is it a glitch of the software (i am running Cyan)?

I got the exact same problem with my own L1020, have been fighting with support to have it fixed, they changed about everything (except the mainboard...) and the problem is still there.
I started to be really angry and got a free Lumia 930 in "replacement"... as I still got the L1020, I tried to put it under W10 preview, and it looks like the problem is really a software issue... with some builds, Bluetooth was working fine, with some the same problem appeared again...
I don't know if you found a solution in the meantime... if you did, I'd like to know what it was, because I like the 1020 better than the 930 (size and camera mostly) and I'd love to have it working with my MS Band
I have been using tasker on my tablet for about 2 years now, and all of a sudden, for the last week or two, it has been acting differently. I have a tablet installed in the dash of my car and use tasker to turn off all radios (mobile network, wifi, bluetooth, etc..), turn off the screen, etc.. when the car turns off (no power), and then turn all of that stuff back on when the car starts (power). The problem is that all of a sudden, after a couple of on/offs of the car, if I use the airplane mode on/off, it gets stuck and I have to restart the device (basically, in the notification panel settings, the airplane mode is half lit up, like it is in the process of turning off/on). If I use the mobile network on/off, it will show that it is picking up the network, but I cannot connect to the internet (shows the bars are full, for instance, like it detects the network, but I can't access any data). Also, to go along with these two things, I used to, when leaving my car parked overnight, come back to maybe a couple percent loss of battery life... now, it is dropping significantly (probably 30+% or so each night).
Anyway, I have been searching around online for a while now and I cannot seem to find an answer anywhere. I installed a new SIM card from Verizon, have factory reset it, and nothing works. If I disable the cell data disconnect (either mobile network or airplane mode), when I come back, it shows the signal bars with a small "x" in it and no connection. Either way, only a restart fixes the connection.
Attached is a screenshot of my devices info if that helps as well as a picture of what the "half stuck" airplane mode looks like.
Any help/info is greatly appreciated... thank you!

Cell standby is eating up all of my battery. I have no idea what is doing it. Any suggestions?
I'm on T-Mobile.
I fixed the issue. It's caused by having WiFi turned on. Hopefully a fix is pushed out shortly but in the meantime this is what I did to resolve the issue: Turn off WiFi, fully charge device, restart and go fourth.
I was able to fix my cell standby issue buy turning of WiFi, fully charging the phone and restarting. No issues as long as I don't turn WiFi back on.
if you use the t-mobile app, they have a feature to automatically turn off wifi once you leave an area that you automatically connect wifi to. it's really interesting. it only turns on wifi and connects to networks you have previously already connected to. I assume it uses gps, worth a shot trying, can't report improvements yet because I haven't tried it yet
Same Issue with Verizon. Although I have no intention of turning Wifi off and racking up a data bill, so thats not an option unless Im out of my house.
Hello everyone,
I have had my E6653 since mid October, and it was working well, however once I flashed a Taiwanese 32.0.A.6.152 firmware I have this bug. Let me describe what actually happens:
1. All stamina modes turned on (clock, extended standby, extended usage)
2. Start using the phone after it sat idle for some time, sometimes even 10 minutes is enough
3. Whatever app you were in, if it requires internet connection, it won't work. Switch apps, try to use internet connection and it still won't work.
4. Wait for somewhere around 15 seconds, and internet connection kicks in.
It happens when I'm both on LTE and Wi-Fi. I have already tried repairing my phone, and flashed 3 different firmwares (CE, Taiwan, UK), but nothing helps. I have seen someone on reddit with a similar problem, but for them it only occurred when they were connected to Wi-Fi.
Has anybody else experienced this? If yes, were you able to fix it?
Thanks for your time!
I was able to fix it by waiting 15 seconds.
Seriously, turning back on the radios and acquiring an IP address isn't instant. Just be happy you have a phone with Stamina mode available if you want it.

I don't think you understood what the problem is. I have LTE and Wi-Fi turned on all the time, never turn either off. Stop using a phone for 10 minutes, turn the screen back on, unlock it, try to use internet connection and then it fails. It hasn't happened on the previous version of the firmware when I had all stamina modes turned on, and it certainly isn't normal. It's a bug, and I was asking if anyone knows the fix. Waiting 15 seconds is not one, unfortunately.
Well one of us isn't getting the issue for sure and I don't think it's me. However, I've been wrong before
You said:
"1. All stamina modes turned on (clock, extended standby, extended usage)"
but also:
"I have LTE and Wi-Fi turned on all the time, never turn either off."
Stamina mode says about Extended standby: "Saves power when the screen is off by temporarily disabling Wi-Fi and mobile data".
These two statements are in disagreement.
So you put the phone down for a few minutes (presumably the screen goes off too), then Stamina mode kicks in and turns off Wi-Fi and mobile data. You wake up the phone after 10 minutes or so => you need to wait for radios to fire up and acquire IP address.
I'm not seeing anything wrong or unexpected with this behaviour...
I've noticed this more aggressive stamina mode myself. In all honesty I can't see a problem with it, it's putting the phone into deep sleep a lot faster (10 seconds or so in most cases) than it was on the firmware before. If it is happening across many different firmwares it is safe to assume that's how it is meant to be functioning. If, in the next firmware, it goes back to how it was it was a bug.
This behavior is different to earlier Xperias so it surprised me as well. In addition the phone shows you still connected to the network which makes it more difficult to determine.
Hi guys!
I did a lot of googling and searching through XDA, but never found a solution for my problem, so I might as well try it here.
Recently I updated my Sony Xperia X Compact to AOSP 10. Now when I am connected to wifi (and it does NOT matter whether it is 2.4/5GHz or IPv4/IPv6, I tried everything) and my screen is locked, my system seems to put the wifi connection into some kind of battery saving mode. Notifications then will hardly come through. You can also see this in WhatsApp Web - every two minutes or so, "Phone not connected" will show up, and messages take up to 2 or 3 mins to get delivered. Then I can use Whatsapp Web normally for 30 secs, after which my phone seems to disconnect again. If I unlock my screen, WhatsApp Web will immediately (!) start working normally again, also missing notifications (e.g. Signal) will then come through.
While of course this might be a ROM bug, I am at least 100% sure it IS ROM-related, as I used exactly the same phone with exactly the same router without any problems while on Android 9 LineageOS.
Another interesting thing - if I charge my phone, during charging WhatsApp Web works completely without problems. The moment i UNPLUG the phone, wifi gets somewhat throttled agian.
Does anybody know a working solution for this? I do not have the option "Disable wifi sleep" or something similar - i believe Google has dropped this option somewhere around Pie.
Thanks in advance!

AFAIK there are kind of wifi energy saving options on some devices. But IDK if you can enable or disable wifi when phone is locked
