TP2 Wakeup on Signal Loss Workaround
 

OK, I figured out something interesting today about my phone waking up when it loses and reacquires a signal. Depending on how many times a day it happens, especially if I'm in a poor signal area, it can really negatively impact my battery life. Its been a problem with all of my HTC phones in the past and is not ROM dependent (Stock or custom).

The best "fix" I could muster and keep functionality was to set my screen to turn off after 30 seconds of non-use on battery and 1 minute on wall power. It helps a little but if my phone is in my pocket and the screen picks up inputs after the phone wakes up, it may still be a while before it shuts off again.

Anyway, I was looking around in the CHT 2 settings and decided to try the "Proximity Backlight Off" setting (From Home Screen: Menu>CHT Editor>Lockscreen> Proximity Backlight off). Well guess what? If the phone wakes up and is in my pocket or holster, it immediately shuts back off.

Verified by covering the top part of the screen - try it: Put your finger or something over the top part (HTC - Earpeice - Sprint) and turn it on. Goes right back off unless you uncover it and slide to unlock. You can also do the reverse by turning it on then covering the proximity sensor and it goes back off unless you slide to unlock.

My guess is that this will also help with phones that wake up from magnetic flaps on their holsters. If I didn't put mine in correctly it would constantly wake up because the magnet was tripping the stylus sensor.

Tried this by removing my stylus and the screen comes on for a split second and then goes back off if the sensor is covered like it would be in your pocket or holster.

Anyway, give it a try and see if it helps.

EDIT: Forgot to add that I am currently running NRG ROM Jan 26 29007 CHT 2.0

Re: TP2 Wakeup on Signal Loss Workaround
 

my workaround is the lockscreen + backlight setting conjunction and/or airplane mode, easier to do than installing a resource hog like CHT but u got a thanks anyway.

Re: TP2 Wakeup on Signal Loss Workaround
 

Yeah, airplane mode isn't really practical for me as I need to be able to make and receive calls, texts, emails etc at all hours. I do use airplane mode in class in one of the buildings that has very poor coverage.

Seems like it happens a lot at hone inspite of my airvana (newer airave). I'll still connect to a distant tower and then switch back at will. I have to cover my phone at night as it lights up my bedroom.

Now the cover serves to trigger the proximity sensor and it turns off immediately.

Now, I'm not trying to pimp CHT but it is running quite well on my TP2 with NRG ROM overclocked to 748 with winmospeed. Funny thing is that I must have gotten a very good phone because I almost never have any of the problems that other people in the NRG threads complain about, partiularly the lag. I'm also getting better than 48 hours without any battery tweaks.

EDIT: Hit ya back with a thanks as well. :-)

Re: TP2 Wakeup on Signal Loss Workaround
 

I get the same issue with my Airvana. In fact, it's 100 times more frequent with it. I have to cover/flip my phone or the light will iiterally wake me up. I wish this option was available on CHT 1.8.5 because I don't think CHT 2.0 is where I'd consider it to be worth using.

Now onto searching for other or native approaches to this solution :)

Re: TP2 Wakeup on Signal Loss Workaround
 

I have the airvana as well and it is ridiculous how often my phone turns itself on. I honestly don't know if the airvana was even worth it and I got it for free lol

Re: TP2 Wakeup on Signal Loss Workaround
 

OK, made some progress. I figured if CHT has settings to control the proximity sensor then there must be registry entries that do the same.
A search for "proximity" in the reg editor reveals strings for both CHT and HTC. By default the HTC settings have a value of 0. There is also a (defailt) that has a "value not set". So I changed default to dword and gave it a value of 1 and chenged the following settings from 0 to 1:
Proximity Detect Status
Proximity Sensor On
Unexpected Wakeup
The only problem that I have is that the settings don't hold after a soft reset. I'm convinced that these changes would do the same thing that CHT does by turning the feature on. So, anyone good with a regeditor that wants to do the same and create a reg cab that can be applid that would stick?
David

Re: TP2 Wakeup on Signal Loss Workaround
 

I made a .cab of it... problem is it won't stick? I tried bunch of things but the only thing that would stay is the default setting. If you come up with a solution, I'll cab it for you.

Re: TP2 Wakeup on Signal Loss Workaround
 

Thanks Kozmo, I appreciate the help. My guess is that since I'm on a CHT ROM and I'm trying to change reg keys in sense, that might be the reason they are not sticking as CHT lockscreen may be overriding the WM lockscreen.

David

Re: TP2 Wakeup on Signal Loss Workaround
 

Next time I flash a no CHT ROM (probably tonight or tomorrow) I will try this before I load anything else and see if it sticks. I'm starting to cook my own and I'm constantly flashing, so it's no problem. I'm on CHT2 now, but don't use the CHT lock, so don't know if that matters?

Re: TP2 Wakeup on Signal Loss Workaround
 

Thanks. I've got midterms this week so flashing is on hold for me for a bit. Thanks for the help.

David

Re: TP2 Wakeup on Signal Loss Workaround
 

What do you mean it won't stick? Does it revert back to default after a soft reset? If so, this thread is related: http://forum.ppcgeeks.com/htc-touch-...y-startup.html

Re: TP2 Wakeup on Signal Loss Workaround
 

Yeah, I had seen that earlier. Just hadn't gotten around to doing it. 200+ pages of genetics and pathophysiology is keeping me from having any fun today. :-)

As far as the changes I make, yes, they revert back to default after a soft reset.

Thanks

Re: TP2 Wakeup on Signal Loss Workaround
 

i think you guys are over thinking this .. a simple Mort script file placed in the startup folder with the reg edits will work .. right ?

Re: TP2 Wakeup on Signal Loss Workaround
 

Thats correct. I just hadn't gotten around to it. FWWIW though I'd really like to prove my idea by trying it on a non-CHT ROM, which I just don't have time to do at the moment.

The link in my post above shows exactly that.

Re: TP2 Wakeup on Signal Loss Workaround
 

I have my ROM loaded , userROM , without sense , I'll try it out for you !

Re: TP2 Wakeup on Signal Loss Workaround
 

oh cool . didn't know that . I was just going off of general knowledge of mortscripts , ive written quite a few .

Re: TP2 Wakeup on Signal Loss Workaround
 

Tried on fresh no CHT ROM and only thing I could get to stay with 1 is the ProximitySensorOn. The detectstatus and wakeup stay at 0? Tried with my .cab (which is just mort script that puts in startup) and just a plain .mscr file I manually put in startup. Curious if anyone else gets it to work? This is the same as with CHT installed, only SensorOn file stays at 1.

Re: TP2 Wakeup on Signal Loss Workaround
 

Wonder if there is another reg key that we're missing. THeres also the "default" key that does not have a value setting so I set it to dword hex 1 and it kept the setting. not sure if that is what it should be though.

Re: TP2 Wakeup on Signal Loss Workaround
 

:headbang:

Thanks for the help though. I know there has to be another reg setting somewhere that we are missing. IMHO, if CHT can do it, then there has to be a way or some settings in the reg to do it without having to have CHT.

Once I get done with exams next week, I'm going to dig a bit deeper into the registry.

Just thought I'd add too that since turning the feature on in CHT my battery life has increased dramatically because my phone isn't staying on all the time now after it wakes up on its own. Results are better when it is in my pocket than the holster though as I think the proximity sensor works better if it detects a little movement such as when the phone slides around in my pocket.

Anyway, I'm not giving up on this so more to come...

Re: TP2 Wakeup on Signal Loss Workaround
 

BsB tweaks has a diable wakeup on sms feature. Try it out.

Re: TP2 Wakeup on Signal Loss Workaround
 

Thanks, I know about that but the problem we are trying to address is when the phone wakes up when it changes from one signal to the next or loses a signa and reacquires it.

In poor signal areas, my phone will wake up dozens of times a day which subsequently drains the battery more quickly.

The setting in CHT I talked about in the first post solves the problem for me and anyone who uses a ROM with CHT. My goal now is to find a way to enable the settings on a ROM that does not have CHT,

This works on my Touch Pro 2 with Titanium.

Re: TP2 Wakeup on Signal Loss Workaround
 

Thanks Ruben, I'll give it a try.

Re: TP2 Wakeup on Signal Loss Workaround
 

This issue has been driving me nuts since my Mogul days too. I am on the Standard NRG and this happens a lot!

Re: TP2 Wakeup on Signal Loss Workaround
 

Tried this on my TP2 with stock VzW MR3 rom and it appeared to work. I thought I had found the ultimate solution. However, the problem is that the proximity sensor then works on everything! For example, when I tried to listen to voicemail (through Verizon Visual Voicemail), my TP2 kept cutting off when I placed it next to my face. The alternative (to play all voicemails on speaker) gave me some privacy concerns, so I ended up uninstalling this solution.
