Hi Guys,
I got my HD2 today and i have to say i am impressed!
I only have one problem which i am not able to resolve.
When i turn on WiFi, it wont turn off during sleep mode (when i turn off the screen). i need to manually turn it on or off. this is how it came out of the box.
I wonder if other HD2 users are having the same problem / found a solution?
I tried advanced config tool, and i unchecked the "wifi during sleepmode" setting, but after each reboot the settings just come back.
Any help would be appreciated.
Hi mate, you should look this

I thought that guy just want to keep WIFI on but you did.
thanks man but it does not help me with my problem. I cant seem to be able to get WiFi to auto turn off when in standby. the reg tweak will work until you reboot the device. after reboot the WiFi again won't turn off when in sleep mode unless I manually turn it off.
Bump.
Can any other HD2 owner please confirm if this is happening on his device too?
Same problem.
HDtweak and AdvanConfig does not work. After soft reset, wifi-on-standby is back ON (checked).
Been trying to find a Auto-Disconnect for GPRS(HSDPA) but the above 2 apps does not work too.
have you tried to change wifi power settings to high? I think it does work then. I guess the medium setting is something special...it keeps the wifi connection alive in standby, but also doesn't consume much power. I have an exchange connection active, so i always need an internet connection. The moment i turn on wifi at home, it stays on, even in standby, and my data connection over 3G disconnects. My exchange still works perfectly...and no huge power drain! My wifi power setting is on the medium setting...
Yes, I can confirm I'm encountering this issue too - on my HD2.
Strange, 'cos I wasn't at first, I'm sure - I remember the wi-fi notification icon flashing when resuming from sleep.
glenner05, can you confirm that you can get wi-fi to sleep please?
Hmm.. thought it might be connected to the htckeepwifionwhenunattended registry value but mine's set already to 0.
There're others trying to do the opposite!

Anyone else found a solution?
I think HTC made this by design. If you turn GPRS data off and leave Wifi on while in standby you will be surprised how low the power utilization is.
I tested and with GPRS data off and Wifi ON, in standby you lose about 2% battery per hour...that's nothing.
It seems that on the HD2 the Wifi power consumption is really optimized so no real need to turn

Mine is on default Wi-Fi settings and when it goes into standby, wi-fi goes off.

Yeah goes of in sleep mode, if you get wifi toggle, you can choose to keep it on or turn it off when you like .
Shame the grps is still a problem....
pgamble and jrvenge: you really mean wifi switches off on the device when it goes to sleep? Ie. you see it disconnect from your router or something?
jrvenge: what did you mean by, "if you get wifi toggle"?
clubtech: when I read your post I agreed with you, maybe. I can't now be certain I remembered correctly that I'd seen wifi reconnect. And yes, the power consumption does seem low
There is a cab floating about here that enables you to force the wifi on always or turn it off.
If you forc on it stays on, if you turn of it goes off.
Return to normal and the hd2 does its power saving thing, so im all sorted there, just need a timeout on the gprs now.
If you cant find it let me know. It works a treat.
can youplease post the cab ? I have been looking for something like this .
Sure pm me your mail and i will send it
GPRS Disconnecting software here fella's, tested and working on my HD2 100%
May also turn off wifi but i've not loked yet, just about to leave for work so will check later!! lol

Ok just tried and it does not do what we want with WiFi
Yes ... if device goes to standby, when it comes out .. you see wi-fi searching to connect again ... so it definitely disconnects and the reconnects when it comes on again.
Paul.
Yup your right!
If it's in balanced or best battery mode then it turns off in standby and reconnects/searches again when you press a button to bring up the lock screen.
Here is a question about Wifi sleep that seems pretty obvious to me, but in case I am wrong I will ask here.
You enable Wifi, which shuts off 3G (but keeps 1X active). Now Wifi goes to sleep (when the phone is in your pocket), and while Wifi is sleeping, someone sends you a GMail. I assume that you will NOT get any push notifications while Wifi is snoozing away???
You should have WiFi set to not sleep.

To expand on Beezer80's comment, you will have better battery life if you set your wifi sleep policy to never sleep. Your power is drained faster with repeated search and connect actions by your phone, so you'd be better off keeping the pipeline open all the time.
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)
Even manually by disabling the wifi, in the chart of the battery, I see that is always connected, even at night, even when the display is turned off, even when there are no other activities!
How so?

I thank you on trust!
This should also consume less battery power or does not change anything?
By changing this I'm now getting about a quarter of a day more. Not a lot but more=better!
Tomorrow I'll know!
Whether you finally wifi turns off completely ... whether the battery lasts longer!
The WIFI locking it manually, is finally off!
Unfortunately I have not noticed improvements with the battery.
But I believe that the increased consumption is due to the data connection.
In fact, if I leave the wifi on, in addition to the data connection, I have a night consumption by about 4%.
If I turn off the wifi and leave the active data connection, I have to consume about 10%

At night, I just turn Airplane Mode on, WiFi on, 3% consumtion.
I will try to turn off the data connection only because I need the radio active to receive any phone calls.
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.
