Backlight problem - Touch HD General

Hi all,
There are 4 options in Power->Advance to set the duration to turn backlight off and power off when the machine is idle (2 for battery, 2 for external power).
Don't know after using which application(s), I found that the first 3 options will sometime 'unchecked', and this cause my HD keeps power on un-notice.
Of course it is not a big deal, but just drain my battery........anyone got the same problem??

XDA2 and wifi sd card

I always get the message that my battery is running low and need to charge it again.
Does wifi card eat power?
Only had out of cradle for 90 minutes or so.
Also is there a way I can see backup battery power?
Only had it a few days and still gettin used to it.
yes WiFi needs power, and so does Bluetooth. but only if it's turned on. Although some say the wifi-SDcard uses power even when turned off.
Adjusting backlight also helps to save power.
Bad reception is also a reason for power consumption.
Start/Settings/System (on the bottom tabs)/Power
There a lot of free today plugins which shows your battery power on the today screen.
What Rom version do you have? Start/settings/System Device information/Version.
I ask this because 1.72 has improved power usage.

Power Button and Data Retention BiG Problems

Hi All,
I have such a big Power issue with the Magician, or at least Orange's M500 version of it that i'm thinking of taking back the device :'(
It doesn't appear to be a device fault, but a design fault.
In the manual it says that if you press the power button for a short time (less than a second) it turns the PDA on and off. This seems to be correct.
In the manual it says that if you press and hold the power button for two seconds it turns the phone off, but this doesn't work. Instead it turns on and off the back light. If the PDA is on, it turns on and off the back light. If the PDA is off it turns it on with the backlight on.
Last night I turned my PDA into standby mode (As i can't turn the phone off) before going to bed. Around 3am in the morning my PDA woke up saying that the battery power was low. I turned the PDA back into standby mode but it complained later on that night. i.e. had a bad nights sleep last night.
I thought it best to remove the main battery so that it wouldn't continue to wake me up, making sure that the phone and PDA were turned off (no power) and let the data backup battery retain the data until i woke up (5 hours time). However, when i woke up the internal data backup batery was flat. It was fully charged before the i took the main battery out. It is supposed to last 72 hours right!!!!? What a nightmare!
I was wondering if anyone could help me answer these power related questions, as i love the device, but its useless if it won't retain the data when it says it should.
How do you turn the phone off so that nothing is running at all? (i.e. to make sure that the internal battery is only being used to retain my data)
Does activating bluetooth drain the main battery faster even when the PDA is in standby mode? (I think i may have left it switched on last night)
Why would the internal data retention battery drain flat in under 5 hours when the main battery is removed loosing all data? Does it need the main battery in place in order to work? Could the phone and the PDA in standby mode by running off of the internal power?
Thanks in advance to any help you can give. As you can imagine i'm very disappointed as i love the functionality of this device.

When you took the battery out and left it out, if you had slid the back down (this is the same as a power off) you would of been ok.
The action of sliding the back down and back up is equvalent to a power off. When you press the power button after this, it is like a cold boot. (Not a hard reset)
I hope that made sense.
So to power off the phone and PDA you have to slide off the battery cover and slide it back on again without taking the battery out. Surely there is an easier way to turn off the phone and PDA that to remove the battery cover?
Thats how i do it. I'm sure there is a different [proper] way, but i'm not sure what it is.
Hi
The main battery when flat enough to power off the pda should have 72 hours data retention, its designed that way... so if it goes flat on friday you will still have your data on monday. thats why it was designed that way and apparently it shuts of at 50% capacity.
Bluetooth active will drain more power.
the backup battery is only supposed to last around 20 mins or less, designed so you can take the main battery out without losing data. this is because Ram needs constant voltage to store contents. hence if you leave your main battery out for more time the backup battery has charge you will end up with a hard reset occuring.
The manual needs to be updated i guess. If you want to turn off the phone you can turn on flight mode which disables the GSM radio functions.
Oh and out of interest for the battery type Li ion, its actually better to keep them charged, they dont have cycles like older batteries. they only have a certain lifespan which starts from the date of manufactor and keeping them at low charge degrades them faster.
Enjoy

So up until the 50% point, pressing the power button just puts the PDA in standby and the Phone is still running. Only when the power goes below 50% ish does the PDA power off completely?
So after the phone is fully charged, the M500 battery life meter says there is 6 hours and 31 minutes of battery life in it. You say that the device will turn itself off at 50% battery life remaining, so that means it only has 3h 15m of useable time before it switches off? Can the phone / PDA be used when power gets below 50% or will it just not power up until its recharged?
Thanks for your help BTW very useful information.
Neil
The battery life meter will say eg 6h 31m, the device will turn off in 6h 31m give or take (usage dependant).
when the device is flat there will be still 50% capacity in the battery to allow for the 72 hours data retention. hope thats clearer.
when it is in that state it wont turn on I think...sorry been along time since i been in that state, untill you charge it.
SpeedN
Surely the easiest way to solve this (and yes I was fooled by the manuals answer to press and hold) is to enable flight mode(which turns the phone off) then turn off ? there are a few apps/ shortcuts that will switch to flight mode easily, you then simply press the off button.
Or did I miss something
I think when we push the power off button (or if we select the machine to be powered off after a period of idle time, through setting), the machine will be off except GSM functions. So when you turn on again, it takes a few seconds to make the machine runs.
You can try if you turn off the button, after few minutes (should be more than 180 seconds), then push the Green button to dial, it takes 3-5 seconds to make the dialing pad comes out.
If you do not select the machine to be power off after a period of idle time, you can use other software to "screen off" the machine, so that when you push green button to dial, it comes out very quickly.
If you turn off the GMS, and turn off the PDA, it will not really get into sleep but will be in the state of retention of data. In any case, when you wake up the machine it takes a few seconds.
Therefore, when you are on the run (say on the street) and make calls frequently, do not power off the machine so that you can make calls quickly.
That is only my experience, I have checked other HP and XDA phones, same results. So nothing to do with the speed CPU and size internal ram.
When the machine is ON, I under clock to 208, the dialing pad also comes out very quickly.
flight mode = on , thats all, it turns the gsm function off, so battery would last long.

how to switch off a MDA PRO Universal and battery life

How do you switch it off ? I have set the thing to switch off automatically after 2 minutes, but its still on after 3 hours and the battery has dropped from 99% to 40%. I had the bluetooth on and everything else switched off.
It is one week old.
Is the battery life normal ?
I'm sure it didn't switch off.
thanks
I have a jasjar. First thing i did, i uninstalled antivirus and skype. I keep it all day on with bluetooth active, and everything off at night. Based on calls and activities i put it on charge every 3 or 4 days.
I have set my MDA Pro to turn off after 3 minutes, and it does indeed turn off. If I don't touch it (turn it back on), the device can go all day with negligible battery usage (a few %).
Bluetooth is off. WiFi is on. 'Incoming beams' are off.
I sync by cable, so the device is powered while syncing. If you sync via bluetooth, then perhaps activesync is keeping the device awake even though it is not powered.
If you turn it off manually (power button on edge near SD card slot), does it turn itself back on? Mine does that when activesync is running and connected. Otherwise it is happy to stay off until I get a call or some reminder.
go to the phone options and change from Auto band select to GSM. Using 3G sucks battery like a mofo
my main issue is that it should have turned itself off
1) in the comms menu, only bluetooth was on
phone was off
wireless was off
beam set to off as well
From 98% charge to 40% in 3 hours, when I hadn't used it at all.
I am sure that is not usual.
So gsm/3g/gprs shouldn't have any bearing on the batt life, as it was set to off ....
was bluetooth actively doing anything during this time or just on and sitting there?
Firestomer, the following eat batteries:
- PIE running in the background
- Camera app running in the background (can be activated when you shut the camshell as it is easy to hit the camera switch on the front)
- UMTS (which is not a problem for as your radio is off)
hi joe
BT wasn't doing anything - I closed the clamshell and left it expecting it to switch off, but I guess it didn't since it chewed through nearly 60% power in 3 hours.
Also, what is the technique for switching it off ? I have pressed the power button to the left of the SD slot, all it does is switch the backlight off. I have held it for 0.5 seconds, 1, 5, 10 ....
I am loosing patience with the thing - wifi isn't working for me and TomTom5 keeps forgetting it has a GPS connection ...
btw what is PIE ??
firestomer
PIE = pocket IE
Two clicks of the off switch will turn the device off
On my device BT only uses about 10/15% of battery over a 12 hr period
Are you talking about svitching the device entirely off? i dont think that can be done...exept if you take the battery out and put it back in and dont turn it back on
yes as close to off as possible when I am as sleep etc, but it guess it needs to keep the clock and alarm and keypressed detect powered ....

Not powering off

Hi all, got my blackstone setup nicely but one of the minor niggles is...
When powerd to mains the backlight drops but the device doesnt power off. My battery settings are
On battery - backlight 10secs, iff 1 min
External - backlight 1 min, device 2 mins
Anyone got the same?
Tried S2U2, wasnt a fan, with gyrator got too many quirks to use in the long term

[Q] Regarding battery life and turning the screen OFF

Hi,
I have three questions -
1. How can I save enhance my battery life ? My battery last very less despite of very less usage.
2. Is there a shortcut to turning a screen off ? The only way I found was to hold the RED key for 3 seconds. Doing it every time is an issue so need a solution to this.
3. When I start my Phone I see the ActiveSync service ON. How can I disable this service ? If not disable, prevent it on loading it automatically ?
