Hardware: Touch HD
Software: WinMo 6.1, CE OS v5.2.20757
Strange behaviour: My house has no mobile coverage, so to stop the constant striving of the phone to search for a signal (and thereby drain the battery), I put the phone into flight mode when I'm at home. Sometimes, however, the searching for a signal continues (IN FLIGHT MODE), and the battery is completely drained overnight.
This is an intermittent problem - it happens about 50% of the time, but the steps I take to put the phone in flight mode are identical each time.
Even stranger (but clearly related): Occasionally the phone will actually FIND a signal, and I'll even receive a text - IN FLIGHT MODE.
I have a friend with an identical phone, and his phone exhibits the same behaviour when he visits my house.
It seems that "flight mode" doesn't always turn the cellular radio off. Does anyone know of a more reliable way of turning it off (without actually turning the phone completely off - I still want to be able to use the rest of the phone)?
Many thanks for any suggestions,

There's been quite a long thread about WinMo not setting flight mode correctly especially in 6.1. A newer ROM should help.

Hello,
I was wondering if anyone else is having the same problems.
When I go to bed I turn the PDA off. The phone is still on.
When I wake about 7 hours later I find the battery is at 60%.
What's the deal? I thought it was supposed to have 150 hour standby life.
I do find something else quite weird. When I turn the PDA off the screen turns off and it all seems fine. I have the button lock turned on so no other buttons will work. After a couple of minutes, if I move the volume slider up or down the PDA will beep. Then if I press any of the buttons such as "Record" "Camera" and "Calander" Nothign seems to happen.
But when I turn the PDA on the "Recoard" "Camera" and "Calander" applications will load.
It is kinda of like it isn't turning off the PDA at all.
Anyone know what I'm doing wrong or how to fix it?
Thanks

if grps is only and bluetooth is on and maybe messenger and or icq is on it drain the batt
GPRS and Bluetooth are both on but GPRS is not connected. And Bluetooth is not connecting to anything.
I don't use messanger.
Would that still be draining the battery that much?

Cyeoh,
Unfortunately, I know exactly what you are going through. Your phone is entering a mode called 'resuming', it’s a low power state that does not turn on the display, etc, but will respond to hardkeys, volume slider, etc......
I'm guessing your XDA2 goes into 'resume' while trying to find a GSM signal, (are you in a weak area). This is my problem, you can read about it here...

As a test, you should turn off the phone, (flight mode) for one night and compare the battery in the morning, (I'm willing to bet is almost the same as when you left it). Alternately install an app that monitors cpu usage, (like the one in the above link), and you probably will see a similar pattern to mine.
The registry solution does help, but causes problems with Bluetooth, (at least it did on my device, nothing a soft reset didn’t fix, but it was VERY annoying)….
If it is your GSM phone, you might want to try using another GSM SIM card from another provider, (maybe a friends) and see if you get better results. When I switched to a better provider I got an increase of 10% on the battery, (not great but something!)
Thank You very much.
That does answer a lot. I do have very bad reception at home. I guess this may mean I need to leave it charging over night. However I do find the XDA does charge very quickly which mean in the time it takes me to get ready for work it is back up to 93%.
I will put it into Flight mode tonight to see what happens.
It's still a little bit ****ty and it seems to be because of software. Hopefully they will fix it in the next ROM update.
Thanks

How did you go with your test last night cyeoh, did your battery last a little longer?
I'm intrested to know as when I charge my battery over night in the morning its still is not on 100% untill I do a soft reset or disable and enable flight mode then it pops up to 100% and stops charging... yet a nother feature of some software I've installed or the ROM version at the moment!!!
I've witnessed this on both the Wing and the Wizard while running WiMO 6.x with various ROMs from various cookers, including "factory fresh".
Why does the battery drain faster when in "flight mode" (all radios off) than when in "normal mode" (Bluetooth and GSM radios on in my case).
For instance, when taking a short flight las weekend, I placed the unit in flight mode, turned it off and put it in my pocket, noting 96% battery charge at the time (as shown by Battery Status). No usage at all during the flight on my part until we landed.
Upon landing, I fired the Wing up, and notice that the battery was at 83% !! No usgae at all and the battery drops13%?! I only drop about 3% an hour during typical standbye. I use Exchange ActiveSync push and Windows Live push options, bluetooth typically turned on and noderate e-mail, SMS and web use (no media player stuff or A2DP).
Am I missing something? What should be turned off to make this drain go away?
I'm not positive but I have heard somewhere on this site that it drains the battery because even though it is placed in flight mode it still searches for a signal w/o connecting to it and being on a plane it has to search even harder because obviously there is not cellular signal. Hope this helps...
Is there a program or MortScript out there that will turn off the radio more often for better battery life? Where I work there is basically zero reception and if I don't manually turn off the radio I only get a few hours of battery life but elsewhere the phone will last for a day or two. Is there anything that will improve this?
I considered writing a MortScript app to do this but I don't really know how to go about it and figured there must be some kind of app out there already...
How about Phonealarm.
It could turn the radio off / on when you tap an icon, or it could be based on a timer.
I have phoneAlarm installed but don't really know how to do anything advanced with it. If you know how to set it up properly that would be great if you could let me know. (Avoids having yet another program running in the background.)
Today I wrote a MortScript file that appears to work ok. It uses a 3rd party command line app (can't remember what it was at the moment) to turn the radio on (if off), then it waits 10 seconds to give the phone time to connect to the towers, checks the signal level, if it's too low it turns off the phone and waits 10 minutes before turning the radio back on and checking the signal level again. Then the whole process just infinitely repeats itself. If the signal is ok it just leaves the phone on.
FYI if you get service roaming, you might want to switch your phone to roam only in these times. I get much better battery life when I do that in these circumstances...
Anyone got any ideas how I can stop my battery from going flat?
According to the literature stuff, your battery on the HD2 is supposed to last for hundreds of hours whilst on standby, why then does mine go flat in a little over 8 hrs? I go to work, put my phone in my locker after making sure its locked and everything is cleared (via task manager) but it is still almost flat (around 25%power left) when I get home..
ideas on a postcard please.
Every time that happens to me it's just do to the build that you're using some are good on battery life others not so much. I started using setcpu to control my phone while on stand by and low usage etc. it does the trick for me.
If your locker blocks the signal, perhaps your battery is dying quickly as it tries to find one. May be best to put turn phone (signal off) whilst in locker. This happened to me the other day when i put my phone in a blackspot at work, and ended up with a drained battery.
The problem might not be no signal, but rather a very weak one.
Some time ago someone on here asked HTC why when the HD2 loses a signal for a short period of time it doesn't find it again as soon as a signal becomes available. The reply was it was a designed to save the battery life. All you need to do was click on the notification bar, at the top of the screen and that would reactivate the phone to start looking for a signal.
If the phone is in a very poor, but constant, signal area then the phone would use a load of battery power to constantly keep in connection.
If you put your phone in Aeroplane Mode, then you should see little drop in the battery level after 8 hours in the locker.
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.
d.a.v.o.r said:

Click to expand...
Click to collapse
No that doesn't normally happens, unless you have an app running under lockscreen and using WiFi (like a music streaming app)
