I have an XDA 2 and its not mine I'm borring it, the battery got low and I didn't want to waste it so I took it out for 15 minutes, then I popped it back in to use it later and it reset EVERYTHING. And now it says charge it up or it will lose it all. Is there anyway to recover what was gone? I don't have a charger near me, should I just rip out the battery - and it wont die? I CANT lose all the data on it
I'm afraid you've already lost everything. By taking the battery out you're forcing the XDA to keep the contents of it's memory purely by using the battery backup, but that only last approx 10 to 25 minutes depending on the charge level before being unplugged.
These aren't the same as conventional cell phones. The memory is stored in battery powered RAM. You should only take the battery off to change the SIM card or change it for another battery.
Even if the phone is flat and won't turn on, the battery contains enough power to hold the memory for a day or two until you can get to a charger.
Sorry - You'll have to restore from backups (if any were already taken)
so should I just leave the battery in now and let it die, its in standby mode, the screens off just the light is blinking.
I've got an XDA IIs instead of a II, but my unit doesn't actually turn on when I put the battery back on, I have to actually push the power button for that. After that it's impossible to turn it completely off without removing/replacing the battery. I would expect the XDA II to be the same with that off/on functionality.
But you should be able to leave it on standby for ages (push the power button when it's turned on, screen goes blank and flashes occasionally to tell you about network signal).
But you've already wiped everything by sounds of it so it really isn't going to make any difference whether you put the battery on it or not. It's not going to come back. This part is definetly the same regardless of XDA IIs/II or whatever. Sorry.

Hello,
My backup battery did not recharge any more. Now, I can not even turn it on (the main battery is fully charged). In my area, there is no replacement.
So, what should I do now to make it work again?
Thanks
your post is a llittle tricky.. how did you know that the backup battery did not charge? and the main battery is full? when you can't even turn your XDA on?
have you tried to hard reset your phone? it might just be a software problem..
I had a trip for 2 days without my xda, and when I came back, I could not turn it on, I guessed that the battery is empty. So, I put it on the cradle, nothing happened. I noticed there were a socket on the cradle to put the second battery. I removed the main battery and put the main battery on the cradle. The led showed in red indicating the main battery were charging. And I put my xda on the cradle again, the red led showed too. After a while, I noticed the led changed from red to blue. It indicated that the main battery is full. I got the main battery out of the cradle. But my xda still in red. I tried for several time, nothing changed. And I put the main battery into my xda. It turned on. And there were a message saying "The backup battery is extremely low, please change or recharge as in the manual". I ran the battery application, it said that the main battery were 100% and the backup battery were 0%. The software started to install like to make a hard-reset. When it finished installing. It were soft-reset automaticely as usual. But the backlight of screen is turn off, and the picture look dummy. That ware exactly the time I can not turn my xda on anymore.
Now, there is something so strange with my xda. When I put it on the cradle without the main battery, the led lights in red in about 20 minutes and then turn off automaticly. But when I put it with the main battery, nothing happen.
I did try for hundred of times, but nothing changed. I guess that my xda is dead.
So sad.....
Maybe your XDA has a problem in its charge pins.
You should let it checked by someone.
I had the same problem as you before, but I exchanged that XDA with the new one :roll:
did you actually hard reset your phone yet? something like this happened to me two nights ago.. my phone went low on batt so i charged it and it was ok then so i turned it off so that it could charge better.. when i came back to check, i cant turn it on anymore so i disconnected it from the charger.. i took off the battery and placed it back.. but my phone didnt respond anyway.. no lights no nothing! my last resort was to HARD RESET my phone.. by placing back the battery and holding the power button while i press the reset button with the stylus.. and voila it's up again..
thanks for everyone, I did find out the problem, that is the backup battery,
I openned my xda and remove the backup battery, It works just like before. I also experience that If the backup battery is dead then we must remove or change the new one then the phone will work. It will not boot or charge with the dead one inside.
Why take out the battery and charge it separately ?
Just put the battery back to xdaII and place the xdaII in the cradle and charge it together. :roll:
im very sorry for my late reply.. if only you recieved it earlier you didnt have to open your XDA and void your warranty.. but it's good that it's ok now!
same here
i have exactly the same problem with my backup battery...i just got my xda 2i today and I tried to charge it up the main battery quickly went up to 100% but the backup battery has stuck into 75% and after a while the orange light become green as if it has charged. It takes either a soft reset or I need to disconnect (either from cable or cradle) and connect again in order to become orange and probably to start charging again...
what's wrong with the damn thing?
yanni

have you checked that your backup battery, the one built into the phone is fully charged before you take out the battery. (check in your settings menu under power)
i have replaced mine from a totaly broken xda (picked it up on ebay) as mine had failed and would no longer hold a charge for more than a few seconds.
i also had major probs with a hi powered battery it kept failing for some reason, totaly losing charge in a mater of hours on standby and this kept hard resetting my phone. so i no longer use the larger batteries.
The backup battery is fully charged
After have taking off the main battery about five minutes and putting on a fully charged one the back up battery might shows the power percentages about 25%.But It almost takes me about 30 seconds to change a another new battery,it's not possible the backup power's problem. I change battery exactly the same way when I do it.That's just too weird it sometimes hard reset and sometimes just doesn't.

The backup battery is fully charged even after having take off the main battery for three minutes!so there is nothing to do with the backup power.
I change battery exactly the same way everytime.Why just sometimes it gets hard restted and sometimes it doesn't.It makes me wonder.
Is this eda ii a broken one?Maybe I should turn it back to the repaireman's house for a few weeks?you know how bad China's services are ,they never do things that customers need.
Thanks your heartkinded help anyway

Thanks the same way though your idea seems not where the problem at.
like i mentioned it could just be because one of your batteries has an intermitant fail, as i said i had the same problem with a hi capacity battery, it somtime hard reset my phone for no reason.
just try buying a couple of new batteries, or lable your batteries and see if its only on one of them that the HR occurs.
hi
my htc touch hd has been a bit jittery for the past week. occasionally just turning itself off or having various hangups.
I have the Stock ROM on it and have not tried to do anything extra to it.
Problem is now it has gone off completely and won't come back on. Took the battery out for 15 minutes and it started briefly and went off again after the very first smart mobility screen.
any ideas?
hard reset if i can get it started or is it a more serious issue?
don
Sounds like you need a new battery.
Hi there,
i agree with stuntdouble, sounds like a hardware (battery) issue. Is your phone still under warranty? If so, HTC could maybe send you a replacement battery?
To diagnose whether it is a battery issue or not, please try the following if possible:
(1) Charge the battery to 100%.
(2) Disable from running or uninstall any 3rd party applications.
(3) Disable Bluetooth and Wi-Fi,
(4) Enable flight mode
(5) Set backlight to maximum settings.
(6) In the power management settings, uncheck any option that would set the backlight to turn off.
(7) Let phone stay idle for 1 hour and check battery capacity.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.
Best of luck.
My 2 cents
This should help identify if it's a battery OR hardware OR software issue
* Is your battery completely charging? (i.e the light in your power button should be green when fully charged)
* Can you access the Bootloader? If you can, will it stay there and drain the battery?
* Have you tried a complete Battery Charge Cycle?
Battery Charge Cycle (As I do it)
* Turn the device off
* Attach to charger / USB cable and charge the device until the light in the power button goes GREEN
* Remove SD Card and enter the Bootloader
* Leave the system powered on in the Bootloader running from BATTERY ONLY - the device usually does NOT charge from an external source while in Bootloader - Either way, just to be safe, disconnect all external power sources
I use the cycle every once in a while on ALL my electronic devices to ensure their batteries are being completely charged and completely discharged. It is my PERSONAL OPINION that ALL batteries suffer from a "battery memory". Google it.
(8) If there is a loss of 40% or more, then this means that battery is faulty and needs to be replaced.

- This is a good method of testing, however it seems the OP can't get the device to stay on at all, which is why I suggested using the bootloader. So no offence intended by posting similar steps. (I'm not a fan of cutting another man's grass LOL)
Ive been having the same problem as well.
The phone would randomly freeze or even shut off by itself and the only way to restart it would be to take out the battery and put it back in. Sometimes, it gets stuck on the "Smart Mobility" bootup screen and I have to take out the battery multiple times for it to actually boot up to the home screen.
It's been a bit finicky with the charger too. I would leave it charging for a bit and come back to find the phone either frozen or shut off completely.
I'm not sure if I'd be able to test if it were the battery if my phone gets moody and decides to shut off. How do you enter the bootloader?

(mine was not battery issue). The problem is corrupt file system on internal storage or memory card. After fixing the file system, I dont have this problem anymore.
how did you fix the file system? Would a hard reset fix the problem?
Take out memory card and do HR.
It should bring device to original HTC state... so yes, it should fix it.
In the meantime, you can check memory card on some PC...
Pretty self explanatory. It was dead for a couple of days, I put it on the charger for almost the whole day, now I get no picture, but the backlight is on when I hold the power down a minute. I bought it at walmart, doubt I have the receipt, and didn't get any extended warranty. Is there a way to fix this issue?
I've got the same issue. I was playing Tupsu, when suddenly my n7 rebooted and there was no picture, just semi-strong backlight. When the tablet died, the battery was about 45-50% and I was charging it through notebook's usb port (original n7 cable). I tried to turn it off, but pressing and holding the power button only made it reboot once again (i assume it was rebooting, since the backlight was turning off and on in a second). I've tried it many times, with tablet plugged into wall/usb charger, and even with the power+volume up/down combination, it would still behave the same way. However sometimes after rebooting there was not only backlight, but also thin, mostly white, horizontal lines, appearing in random places of the screen (appearing and disappearing after like 50-100 ms). It would stop only after a reboot, and happened every 5-10 reboots.
I've decided to let the battery die to see if it changes something, and as you may guess - it didn't. It died estimately after 2 or 3 hours. Now it's all the same, except for when I plug it to the charger, there's only a very low backlight (still no picture) and it's blinking... It also makes this continuous "electricity-related" (sorry, I don't know what's the word to call it ) sound. After I press the power on, or let it charge for 1-2 minutes it boots up, and there's just a semi-strong backlight, like earlier.
It's a refurbished 8gb n7, which I got 5 days ago from the polish Asus online store. Oh, and the speakers weren't 100% fine, if it changes something. They were fine at first, but after i plugged headphones in and out, they were making cracking sounds when the volume was over 50% or something like that. Is there any hope I can fix it myself?
edit: the android ver. is 4.2.2, not rooted
the device is getting warm on the left side when being charged, or just turned on...
Have you tried pulling the battery for a couple of minutes?

Nope, i don't want to mess with the hardware since i've bought it only few days ago... I'm afraid it may leave some traces of being opened, i'm not willing to take the risk.
You won't leave a trace pulling the battery. Just use a guitar pick or credit card and run it round, the back comes off very easily.

Yeah that is definitely worth a shot. Just pull the battery.
Ok, I did it.
Didn't change a thing >:[
btw. I didn't actually pulled off the battery, i've just disconnected it - it doesn't make a difference, does it? and another thing - the backlight was turning on immediately after connecting the battery... with these randomly popping horizontal lines.
I've got this too!

I've got this too! Pulling the battery does nothing. Last time it just fixed itself, now nothing.
Worried I'll have to take mine back.
How did that 'fixing itself' happened to you if i may ask? And how long did it last?
Your tablet has gone into sleep mode to protect the battery from further damage due to its low level of charge. What you're seeing is by design, as complete discharge of a lithium based battery is bad for it. You should never, ever, let it sit dead for a couple days. If you do discharge it to the point of shutdown again, immediately put some sort of charge on it, as waiting to long will cause the battery's protection circuit to fail completely. Best practice is to not let your device go to the point of shutdown, but rather to plug it in when not in use. Your battery will have a longer lifespan.
Plug your N7 into the charger and immediately press power and volume down to get into the bootloader. Once there, use the volume key to scroll to Power Off Device and then press the power button. After it powers off, unplug it and then plug it back in. It should then charge normally.
You seem not to have read my posts at all. When it happened, the battery was about 45-50% and it was plugged into the laptop's usb port. It suddenly rebooted and there was no more picture, just the backlight - and it lasted for like 2-3 hours (maybe even longer)! Can a completely discharged battery power the backlight for this long? After it turned off at last, i put it on charge and i've tried the power+volume method and it didn't do anything (btw. i already wrote about it)... then i let it charge for like 5-6 hours and it didn't change anything except for the fact, that the battery was evidently charged, because the backlight again lasted for few hours.

Actually, I was addressing the OP without realizing that this was a zombie thread.
To answer your question though... yes, when in sleep mode the battery can still turn on the backlight and keep it powered for some time due to the low power requirement of a black screen. Many users that have found themselves in sleep mode actually have their tablets enter into a prolonged cycle of bootloops. From the sounds of it, your device seems to have, for reasons unknown, put itself to sleep.
Anyway, I digress... I know you've stated you've tried various combinations of the power and volume keys. Have you attempted holding all three buttons for approximately 30-40 seconds while the tablet is plugged in? If it that will force it into the bootloader, you can follow the steps that I posted to get it up and running again. If not, then it seems your best available option is to seek an RMA from ASUS. Given your speaker issue, I'd send it back regardless- you shouldn't be expected to deal with battery and speaker issues after only five days.

Yep. Many times. And even longer than a minute.

Hi,
One thing that is really weird started to happen recently.
(About Once per 10~20 days)
#And it's that my Note4 just suddenly die in the middle of usage no warnings.
#The screen becomes totally black no LED lights, and pressing the home or power button doesn't wake it up.
#the only 2 ways to turn it on back again is either you have to plug in the charger or remove the battery and put it back again.
Now i thought that the battery is probably the issue.
But the strangest part is that. When i turn the phone back on The battery still has the same percentage before it died so i can simply continue using the rest of the charge without any issues. (Apparently it holds the charge just ok?)
It's almost like getting turned off by it self except you can't turn it back on unless u connect a charger for a second or reinsert the battery.
Note that: this isn't the original battery that came from the device as the original one started to have less screen on time than before about 3.5 to 4.5hrs not bad but the newer one i bought which is supposedly original or atleast the highest quality i could find it gave me 5hrs to 6.5hrs of screen on time.
I'm not sure if it's the battery or a software bug.
Any help is appreciated.
Thanks in advance.

If this doesn't fix then 100% battery issue go get a new battery.
