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.
Hey guys,
i have a weird problem. I'm depending on the wifi from my neighbour atm (he gave me the key - everything legit ) and i tether it via my Desire HD to my PC. But there's this strange behaviour i discovered: When the Display is turned on, i get a ping of about 30ms. When the Display turns of it rises to about 600-800ms.
I have a rooted DHD with Cyanogenmod 7.0.2.
I tried to fix the CPU speed to 1GHz - Performance with SetCPU but it didn't help and i set the wifi connection not to go in standby whilst the display is off.
Does anyone have an idea about this?
Jack
It seems that some of the DHD's Hardware does go into standby although you disabled a few options.
Maybe this could be solved with another kernel, but i guess you would have a higher battery drain then, even without tethering.
Why don't you just leave the screen on? Start its desktop clock and it'll be a nice gadget on your desk

Hi Jack,
I have a base rom or whatever it is called. I have the same problems. I tether using my 3G connection. When the device display is turned off, the tethering has speed issue, while it is turned on, tethering works fine. I haven't found a solution yet. i just keep my display on, since its connected to pc, it will be in charging state.
Regards,
HD
Hey guys,
thanks for your replys, the best idea would pobably be (for now) to leave the phone in "desktop-clock-mode".
Thanks for your Help
Not a fix but a work-around...
Since I guessing the phone is connected to the PC, could you not set the phone to not sleep when charging (menu -> settings -> Applications -> Development -> Tick "Stay Awake")? That way the screen will stay on when ever it's charging be it mains or via USB
(EDIT: Appreciate you get this using desktop clock but this saves having to mess about every time.)
Change your wifi power saving options. The behavior you get is default, to save battery life. It's under the advanced settings in the Wifi settings, IIRC.

If you're talking about the sleep policy the OP says he's done that already.
Changing the sleep polici doesn't do it
Thanks for the hint with the display staying on while charging!
Hi guys
I noticed countless times that randomly when turning on wifi and then turning it off, the "always allow scanning" under advanced options is ticked.
I noticed this because then under battery usage you will see wifi active even tho main switch is off and 99% of the time that is why.
Is it a lollipop 5.0 bug or is it some of my apps that can switch that option when they detect wifi has been activated?
Also, it seems that if i dont turn on wifi in the first place, that option never becomes active. Battery life is very good on my phone so not a deal breaker....
Anyone knows?
Thanks
Hey guys, I am having some problems with my battery on cm13, it's good when I am using the phone but standby time is just horrible, in 15mins i lose about 3-4%. Does anyone else have this problem,and do you know how to fix it?
First try and update to the newest cm13 nightly
Also look at battery in setting menu and see what uses your battery the most
Also turning off features such as wifi Bluetooth nfc and data connection and turn off wifi and Bluetooth scanning and location except when you need them
If you have a weak 4g cellular signal you may
Need to switch to 3g in network settings some custom kernels have atrocious battery life also sorry to throw a book at you but the all that apply to you
Turn off sync also helps a lot
Turn on efficiency or power saving in battery settings also helps
Then turn on simulate color space monochrome in developer options
Turn off ok Google also
Also turn off usb debugging when your not using it

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.
