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.

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.

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.
can someone please show me how to shutdown my phone completely when I dun need it. to save battery. event when I turn off everything on COM Manager, (radio,wifi,BT...everything...).but my battery still droped. thanks. i wonder what eat my battery when everythis is off.
Your PDA is never realy off. As long as the battery is in there, and it has power... it will run. When you press the "Off" button, the device goes into some sort of stand-by mode.
I don't know the technical reason for this, but what's the use of a Personal Digital Assistant if it can't warn you of appointments and such It has to be able to wake itself (Same goes for the phone)
Battery calibration is simply done by running it down completely until the phone shuts off by itself...
Then remove the battery, wait 10 seconds, insert again, repeat...
If the phone shuts off again in less than a few minutes you're done.
Now remove battery and hold power button for 1minute.then insert battery.dont switch on the phone. plug the charger and recharge the battery fully until the green light is on...
then remove battery,hold power button for few seconds,insert it and switch on the phone...
yes its done......
do this initially once in 3-4months when the phone is new.then ince a month after a year to gain maximum battery performance...
REMEMBER THIS WILL NOT DRAMATICALLY IMPROVE YOUR BATTERY LIFE....
BUT THIS WILL SAVES YOUR NEW ONE TO BE DEAD BEFORE AGE
DONT EXPECT MORE FOR ALREADY SWOLLEN OR DIED BATTERY...
no one is interested to test it?
tested, working fine, but i haven't impoved battery life, and also my battery works same as first day. I recommend to use this on all types of batteries LiIon, NiCd etc...

yes this works when you loose your first few % from 100- 80 very rapidly and then your battery become stable...
ok thanx for feedback...

yupz... u're right bro...
i am a flashing junkies and i always do this after flashing to WM 6.5 ROM.
last nite i've just flashing Onyx 5.1.1 ROM (the fastest WM6.5 ROM i felt) . well.. as expected from every WM6.5... battery drain veeeerry Fast!
i just use it normally till switched off on it's own. then charge the battery (while my elfin still turned off) and...
voila....
from 08 pm last nigt till 12.00 am today, it's only consumed 10%!!!
WOW!!!
in fact, i use G-alarm (which usually drain my battery faster in WM6.5).
and this morning, it's need 30 minutes my G-alarm ringing to woke me up.
YES I WANT THAT ALL MEMBER SHOULD TRY THIS AND GIVE THEIR FEEDBACK..
@saurabh bro i tried it...but it dnt workd...
while doin battery calibration thru ur method i came across this thng-
wen power shuts and i wait for 10sec and reinsert the battery and switch on d phn...it gets on smart mobility screen appears and then htc logo cums ,phn gets switchd off....to my surprize it again restarts.,.i havnt presd the power button dis tym...wat shud i do...????
I´m Interested!
What i do?

well is this happen after the callibration?
Its working :d :d
I´m going to test it ..but: One question
how did you figure this out?
and what should the pressing of the powerbutton do .when no batterie is in it?

this is called "POWER CYCLING"....when u hold your power button for a while when no battery inside it drain your backup battery which resposible for your device to remember date,time etc.....
after doing this all the power from the device will be gone....
after that u can do the procedure otherwise it will not gives u good results..
i have tested it myself
It works fine for me!
Now battery drain is proportional to the usage and for sure battery life is longer

Same for me, battery drain is almost half it was before.
I'll give it a go...
no change in battery life whatso ever.tried it in the same way as u mentioned.i have elfin with battery of 2yrs.any suggestions??

Very interesting, I did not think/know it before.
I'll do in the next days (I have other 2 batteries backup).
Here is my findings about battery drain caused by gps.
If I turn on gps and then open any app that use gps (iGO and GPS TEST in my case) it works as it should. But problem is when I turn off gps (and close apps) phone can't go to standby mode and it has high battery consumption about 3-6 % per hour.
I noticed that in this situation if I want to unlock my phone, i can activate screen by pressing back button (it should be activated with middle button and power button, only).
If I turn on gps, again, battery drain stops, and it seems there is no battery drain untill I turn it off, again.
I tested this with two roms: GC 8.5 and aticmv2, both with naa08b kernel.
Please let me know Do You guys have this problem, too.
If not, let me know which rom/kernel do You use.
I have the same issue with GingerDx v020 , when i turn gps on and after a while i turn it off it still drains battery so i need to restart the phone to fix that.I dont know if there is any permanent fix .
I guess this is the same on all roms.
By the way, I tested battery life when gps is turned on (but not used by any application) and it seems that it doesn't consume battery at all. after 3h it was 1% consumption in standby.
So, I will left gps turned on all the time, rather than restart phone everytime I use navigation.
Very bad bug, when i go bed and i leave my p6800 in charging i dont power off it,so when the tablet is fully charged the screen turn on and remains on until i wake up and turn off it manually with the standby button. So the screen remains on for about 4 hours per night! How can i do for automatically power of the screen when the tablet give tje allert that the battery is full recharged?
Did you try the screen timeout under settings>screen? As far as I can tell, it applies even when the device is plugged into a power source. I have similar practice as you but in the morning, my device would be charged and the screen off.
Sent from my GT-P6800 using xda premium
Yes, i have put the timeout to 15 seconds, but when the battery is full charged,my tablet rings and power on the display with the message that the battery is charged, i have wait 20 minutes, but the screen remains on. The only way to power off it, is by pressing the standby button wery boring, i am constricted to recharge my tablet from power off status ,in order to avoid this issue this is bad becouse i reiceive emergency calls during the night
can application->development->stay awake help? uncheck it

Omg i dont was know this option, i have unchecked it and there was exactly described his function! "The tablet never go in standby during charge" . I am sure that this can fix the problem, i cant see for sure now becouse i have 80 % of charge, but i'll let you know tomorrow, i am sure that the problem was this thx so much
