Is any way to sefely turn-off the whole system before i remove the main battery(and disconnect the device from power)? I often remove the sim-card and therefore the device everytime reboots itself. I thing this may cause the system unstable. Or is it not as a PC-Windows?
When you flick the red batery holder it turns the device off
...
That I know! If I pull the battery holder,then I cut-off the power even though the system is running. My question was:Is any way to safely stop the running system before I cut-off the power?
Changing battery
To avoid a hard reset when changing the battery close all running programs using start-settings-system-memory, also set phone to flight mode. Should do the trick!

I removed the battery cover today and noticed a switch with the padlock open/closed symbol.
There's no description of this in my manual.
Does anyone know what it does?
Thanks
When locked, it locks the battery in place and switches the device to use the main battery. When unlocked, it switches to backup battery to maintain memory contents (for a SHORT while - supposedly about 20 min.) while the battery is removed.
Make sure it is in the correct position while the battery is in place or you will get an unintended hard reset when your backup battery goes flat.
Thanks for that.
Is there a way, maybe using mem maid, to turn wifi on at boot or upon wake up ?
What would the command be.
Whenever you soft reset, WIFI id turned off. I am sure this is to protect the battery life no ?
There are little programs like WifiTempON.exe how turn Wifi on (and off) you can put them into the startup folder.
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)
Hi,
I have an Imate JAM, it does now show battery status. When I go to Settings -> Power, it shows 0% and with it, it says 'Unknown.'
What to do?
It does charge, but doesn't show charging status.
have you tried a hard reset ?
Yes, I have tried hard reset. It used to happen occasionally. The phone does charge. I know it because if I don't charge, it just shuts down to let me know that the battery is fully empty now. This error occasionally gets fixed. It does sometime start showing the battery status, but then again goes back to the problematic condition.
Try using other battery meters like "Ariel battery meter" see what they indicate.

do u live in a city where temperatures are near zero? this could be one reason.
or
backup ur data on storage card, flash rom 1.12.00 and see if anything happens.
or
if ur device still works perfectly with this problem, ur magician is having a hard time determining the amount of battery remaining...can still contuniue with it.
Hey everyone. I was hoping someone would be able to help me with this. I've tried searching for this issue but can't find a solution.
Basically over the weekend, I noticed my phone has been running hotter than usual and battery is draining within 3 hours. It gets hot to a point where the phone automatically shuts down. The phone can be just sitting on my desk with the screen off, idle and it's hot with battery draining.
On battery usage graph, it constantly shows that chrome is using 33% of the battery in the last 24 hours. I disabled chrome but the problem still persists. I went into developer mode and cross checked all the system processes and saw nothing unusual. I booted into safe mode as well but the problem is still there. I checked CPU-Z and I see that the processor is never below 50% while the phone is idling. I'm not sure what's using the processor this much that the phone is running hot.
I've uninstalled most apps, I've even turned off the cellular network and wifi but the problem is still there.
I don't see any physical defect or any bulging on the back of the phone or against the screen.
I'm about to factory reset this phone to see if this fixes it, but I was wondering if anyone has any suggestions before I do that.
Thank you!
Try temporarily disabling Google play Services and see if this helps. Any cloud app is suspect.
Disable Google Firebase. Clearing data in Google system apps may get it.
Is Global power management disabled? Do so if not. Disable any adaptive battery etc services.
Deal with power hogs on a case by case basis.
I would try to find the root cause rather than do a factory reset as it is likely to reoccur. Exceptions; malware, firmware upgrade/update, a 3rd party app that change hidden users settings (if rooted you have access to these... if you can find the altered one). You need to play with it and try to track it down. Get the tools you need to find it ie detailed app/services power usage.
Be careful though as you are burning up the battery. Power off the display once battery temp reaches 103F. Cool it down then proceed again.
Using a damp microfiber cloth will help to cool it.
Any resent upgrades or updates?
Any app recently installed or uninstalled?
What apps are using a lot of internet bandwidth?
Is it using excessive current with screen off too?
What's running at startup?
