Yotaphone stuck in extreme power saving mode - YotaPhone

hi all,
this morning I activated extreme power saving mode as battery level was very low, neverthless it completely discharged and the phone poweroff.
After about 1 hour I attached the phone to usb charged and now the battery level is about 30%.
The problem is that I cannot switch off extreme power saving mode.
Main display is off, EPD displays shows extreme energy saving info (but it's quite blurred). If i press the on/off key nothing happens (even in case I keep it pressed for long time).
The only thing that I can do is to access recovery (I have TWRP) that works normally. But when I reboot I go back to power saving mode and cannot do nothing.
Of course I guess I could fully reset the phone through recovery, but I would not do it (since it would take very long to set up everything again).
Do you know how could deactivate power saving mode (for instance deleting / modifying some file in recoevery)?

Actually solved, flashing the ZIP of System with TWRP. No data lost.

Missing icons from bottom of screen

I seem to have lost the ability to rotate the screen and also to switch input modes (keyboard/pen) on my XDA IIi... The respective icons are both missing.... Does anyone have any ideas?
Oh, on a related note, the device seems to guzzle power - I get about 12hrs from a fresh battery (and I've tried three). Any suggestions?
On the power front, I presume you're on an XDA2i? Is your turbo mode on? Is Bluetooth on constantly or wi-fi? What are your power save settings? You'll need to be more specific.
Cheers

Turbo mode is off. Power save settings are default, or more conservative (lower brightness on battery, for example). Yes, it's a 2i.
I've recently rebuilt my 2i (with all the same software as before) yet this time it also seems to guzzle the juice. Turbo mode is off, and I can't think of anything that could be causing it as last night the wireless was off and yet when I woke up it was 23% battery!!

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.

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.

completely shutdown UNI

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)

Flash disabled with low battery power.

Is this normal? I was on about 19% and it refused to enter the camera app, giving an error. A soft reset fixed this but the flash refused to start but is now working normally following a charge. Was this an intermittent fault or normal?
Cheers.
Yeah, this is normal, using the flash with the battery power that low is a bad idea for the battery, can cause an abnormal discharge I believe.
This is normal.The limit they made is 20/100 for battery.After that flash light is grayed out.

Battery saver at night ?

When you don't have to charge your phone at night and with the doze function integrated in the Os, using the battery saving option makes any sense?
Someone measure the differences with and without power saving enable to know how much battery you lose in one night ?
thanks
So, after a few day testing, my results are:
With power saving mode, i lost about 8% in 9 hours of sleep.
Without power saving mode, i lost 6% in the same 9 hours of sleep.
I wasn´t expecting that.
Basically the same I got....I see that with power save I only get +-30 minutes more battery time then without power save.. No use then for me to really use power save
