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.

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.

Noticed something strange with battery level

Hi
I have noticed something strange happening with my phone. I have started charging it every night now so that it will be fully charged the next day.
When it is fully charged, I turn it off completely to save the battery, and to stop noisy email alerts. In the morning I turn the phone back on and it says 73% battery level, despite being turned off overnight, so nothing should be draining the battery.
If I leave the phone on Standby overnight the battery level is always 90%+ the next morning.
What the hell is going on? Does anyone else notice this quirk?

You can try another battery and oberve if the problem would still occur..

It could have something to do with the difference in temperature? In the morning it's coooled off and maybe that does something with the measurement?

Did you put ur fone into flight mode.

Huh, I've never heard of that before, but then I never turn mine off. When you say "turn it off" I am assuming it is when you hold down the off button for a few seconds and answer yes to "really" turn it off. I think its very strange that it uses more power off than in standby. Maybe you have come across a nasty hardware bug. Keep us posted.

Yes I do mean holding down until it tells you data may be lost are you sure.
And it is still doing it. If I fully charge my phone at night and then leave it on standby the next morning the battery gauge will say something like 96%.
If I turn it off, it is always under 80% the next morning, this makes no sense. I leave the phone in standby now with the volume off, and the backlight and power set to switch off.
I keep it in a cradle now, this is a stock photo, not my phone in the cradle.

Charge your battery to FULL, then take it out of the phone when going to sleep, when you WAKE up, put the battery in, if it's at 100% or 99% then it's your PHONE. If it's at 96% like you said before then it's your BATTERY.

Memory card draining power
This was a ROM bug on i-mate JAMin on the first ROM versions that was available. A memory card inserted will drain power from the device. What brand do you have and do you have a memory card inserted ?

Battery drains while shut down?

My battery had a full charge. I shut down the A7 (not standby), went to use it a day later and it wouldn't boot up.
Why would the battery drain while it's shut down? Anyone else experience this?

The only thing I can think of is the device was in sleep not shut down.
I have shut mine down after a full charge and then the next morning the full charge is still there.
If it keeps happening then something is wrong with the device.
Rob

Thanks, I am quite sure that I chose power off, but of course I'm not infallible.
I'm paying close attention (hold power button for 2 seconds, select "power off" not suspend), so I'll have to monitor the situation when I'm not using it as much.
By the way, last night after posting this thread, I shut off the Wifi and Bluetooth. I know those affect my phone's battery.
Does anyone else need to disable Wifi and Bluetooth? I don't recall it being in the manual.

After charging full, dies out.

So it happened again. Fully charge the TF for a trip. When I get to my distination (8hrs later) turn on the TF and its dead. No power and no chargers. This thing is pissing me off!
Anyone know why or how I can fix? I do have the wifi off when screen is off.

How is that possible?
Did you not shut down your TF?

It looks like you are having the reboot during deep sleep issue that started with the upgrade to ICS. The reboots can be stuck with the screen enabled and the processor actively trying to complete the boot, which drains your battery.
Short term, I would avoid leaving the TF powered up unattended for long periods.
That will prevent the total battery drain. For a longer term work around, you can try an app called Wake Lock, which you can set to prevent the TF from going into deep sleep, and eliminate the deep sleep reboots, which has helped some users, including me.
The app should be set to restart on Reboot, and select the Partial Lock, then select the Acquire Lock setting, on the red bar, which will switch to green, and indicate that it has acquired. You can also set it to show its icon in the Notification are, so that you have a visual assurance that it is working. Then just exit the app, and it will work in the background.
You can monitor that it is preventing Deep Sleep, using the CPUspy app.
I would then watch carefully to see that you aren't experiencing any more reboots during Deep Sleep.
Long term, ASUS is researching instability with ICS, and we hope to get a true fix. Until then, use of Wake Lock may help you.
Others may have other opinions and explanations, and they may be right, but this has cured my problem for the last 11days. Good luck.

No shut down. I would charge the TF to 100%. turn the screen on to see if its 100% charged and that's it. Then 8hrs or so later when I want to go use the TF, its dead. Can't even turn on.
Can this be the reboot issue or an application that is running and not letting my TF go to deep sleep? Help!

Your response makes no sense. You say TF was shut down then you say TF might not be going into deep sleep. If you power the TF down it will go off and use NO battery. you will get some battery internal discharge but TF will not come on an use battery. Try the same test shutting it off.

Ok...try again. I would charge the TF. Then check by pressing the power button. The screen goes on and shows 100%. Then press the power button to turn the screen off ( not turning it completely off).
When I want to use the TF, it won't turn on, as if its completely dead.
Suggestion?

its either a) you get a RR and get stuck in a bootloop, b) you got some app running that drains the battery, such as Winamp or c) your device is broken (not likely).

Screen stays on after battery gets fully charged

Got a weird problem with my AT&T stock non-rooted S4. About 4 or 5 times since I got it on release day when I charge my phone and I get the notification that it's fully charged the screen won't turn back off. I use a Belkin Conserve socket that is set to shut off after 3 hours and I've woken up after charging to find the phone dead. I've managed to catch this happen once and when the fully charged notification comes on the screen won't go to sleep, it just stays on and flickers a little bit. For all but one of these instances I had blocking mode on so I'm not disturbed by email or text notifications in the middle of the night. It did happen one time when I didn't have blocking mode on. I use a pin lock for my lockscreen and usually have BeyondPod playing overnight (only one hour long podcast while it's still charging) if that makes a difference. Is the function that enables the screen to stay on when you're looking at it malfunctioning? Any help? I've attached two screenshots of battery life when this happens.

So in settings under the Developer Options, there is a setting "Stay awake" if checked screen will never sleep while charging. Now I see that your Belkin shuts off the power but your phones still detects the usb plugged into a power source.
I think things happen in this order: you hookup your phone to charge and shut off your screen, phone charges to 100% and screen lights up saying fully charged, it stays on because of that setting, Belkin kills the power, it is still hooked up to USB so ... you get the rest.
I would find that setting and disable it.
if your next question is "I don't see developers option" it is hidden by default in android 4.2.2 so to make it available, go to Settings > About phone and tap tap tap Build number seven times. Return to the previous screen to find Developer options. Or Indiana Jones might pop up and give you the cup to get eternal life !!!

Thanks for the reply Commodore64 but I already checked that setting when it happened the first time and it's not checked.

No one else has had this problem?

I have this problem as well as my wife's S4. around 3am, I notice our room is bright with our two phones' screens on. It will stay on until the morning.
In the developer's section of the settings, the stay on when plugged in is NOT checked.
Also, on our phones, we notice the phones overheating because the screen is on for hours at a time at night.
I've just spent an hour looking through the internet, and while many report this, they are simply being dismissed by others as in having "checked" the setting in developer section.
Also, when the batttery does get fully charged, the "Battery if full, unplug the power" notification also rings the default notification ringtone. I've installed phoneweaver to set my phone to no sound overnight, but it only stops the sound, the screen still stays on and phone gets really hot.
This is turning out to be a huge problem for us.

Do you use a PIN (number) lock? I did but switched to the pattern unlock and it hasn't happened since. Also, I've been trying to charge only during the day or evening, not overnight. Maybe, since I charge during the day and I use it periodically while it charges it doesn't go into a "deep sleep" like it would if it charges while sleeping and the full charge notification would keep it awake. I don't know exactly why but it hasn't happened since. Hope this helps.
