Lose everything when battery is removed.

Hi Guys,
Whenever I remove the battery from my XDA 2S I lose everything and have to set up the OS from scratch.
I have spoken to O2 and they have told me this is normal? But how can this be? It is the most stupid thing I have ever heard.
Please if someone could just tell me if their XDA 2S does this I would be more than grateful!
Thanks in advance.

Go to settings/ Power icon and check the status of both the Main Battery and the backup Battery, the first could be at any charge % the backup Battery should be at 100%, this is used to hold the data on the phone for a short duration, sim card swap or battery swap with the machine selected OFF first. If its loosing data then there is something wrong with it, I can remove the Battery on my IIs for 10 mins if need be without a problem - Mike

Yes the Backup Battery is at 100%
It loses everything as soon as I take the battery out, I can put the battery straight back on, start the phone and OS setup begins.
When you say selected "off". Do you mean quickly pushing the power button once.
I have done this and still it loses everything.
Looking forward to your response.
Jonnycash!

All I can sugest are two options
1, Return the phone as it is clearly faulty, demand O2 repair the unit or try for an Exec as a replacement as re-compense, you might get this easily as they are no longer offering the IIs.
2, install something like Sprite back-up and configure the back-up to re-install everthing hardly ideal, and this is not what I would do.
Mike

Yes, I have just got it back from being "repaired". they said that they replaced the circuit board but it still does it.
I will send it back as suggested and try get a new one.
Thanks
Jonnycash

After taking out the battery, try not to push the tab(the one you pull back and the battery pops up) that holds the battery back into place until you re-insert the battery.

Sounds like a duff backup battery to me ( see pic), changing the mainboard would seem a sledgehammer to crack a nut. I have had this with blueangels after re-assembly, even with the backupstatus at 100%. I leave on a cradle charging overnight then do a hard reset - seems to work for me.
Richard

i have that problem as well before. but maybe this will help you a bit.
because i always do it removing the battery when changing my sim card. how i wish they would put the sim card away from the battery. ( calling the attention of the engineers for future references).
i started on the permanent save check mostly on contacts and appointments (I needed them all the time) (start>settings>system>permanent save). then i usually turn on the flight mode then turn off the pda from the power button.
thats the time i take the battery off and either to swap the sim card of the battery. then it automatically go to soft reset when the battery is back you will notice that after the automatic soft reset, there will be a small window showing appointments and contacts restoring.
i hope this will help.

I've had this, once. I've heard that this is a bug of that little black thingey that holds the battery, because it supposed to switch between backup battery and normal battery. Too bad sometimes it does not do this at all...

finally this happened to me to today. I by mistake took the battery out and when I put it there again, it hard resetted itself. Many of my notes were stored in main memory, which I had taken from my teacher just 30 mins ago

It happened to me again few days ago, under 2003SE (I had to downgrade for something). One thing i love in WM5 that I don't have to worry about this.

It has happened to me many times as well as I am always changing batteries. As somone mentioned above it seems to be a bug with the battery holder (the little black tab you clisk to hold the battery in.) I just keep my contacts backed up each time I add a new one. as for the applications they can usually waite till I restore them.

need solution..
need a good and working solution for this...........

Eeerrrr. how about ' replace the battery' - they are standard cells...
Richard

Mabey its not clear what seems to be happening here
When you drop the unit and /or when you open the little black clip that holds the battery in place. Somtimes the phone looses all stored information and goes to hard reset. There seems to be 2 bugs in action here.
1) The batterys seem to get into a strange state where they dont work properly. (I have found that putting the battery into the rear slot of the charger reconditions it to fix this problem.)
2) Some units seem to have a bug with the battery latch when you open the latch accidently or somtimes even just when changing the battery intentionaly it seems not to switch to back up battery corectly. My theory is that there is a dead zone in the latch that does not make the correct transfer if it isn't fully engaged in either direction. It is a really poorly devised way to handle battery changes but hey its too late for them to redesign it. I can not say how many ppl have this issue or if it is everyone or just some people but I do know this is the case on mines and many of the forums I've read.
Solutions:
1) Back up your unit whenever you add data to it. you can just do a contact list back up which only takes 1 min for me and my sx66 has over 2k contacts. Do full back up once a week that should cover your apps and data.
2) Keep your battery reconditioned at least once a week use the rear charging slot for the battery. If you only have one battery this is not an option so I suggeest if you are going to keep your sx66 for any length of time buy a spare battery.
3) Recently I have begun using a small peice of duck tape to secure my battery latch. It is a pain in the rear but I have droped my unit once in this configuration and the battery and latch stayed in place.
Additionaly:
To make restores easier you can include some of your favorite applications in your ext roms. Just snoop around in the forums and you will see directions for manipulating ext rom.
Also look into changing the directorys where you store information. IE your mem card and the onboard storage directory seem to never get nuked unless it is done by the user.
Anything short of the above listed or replacing the hardware is not viable, because these are HARDWARE bugs. Version 5 avoids this issue because it does not hard reset your data like all previous versions of ppc. However the hard ware issue is still there it just doesnt effect you. But if you upgrade your rom be carefull because you are trading the bugs you know for the ones you don't know...lol

thanks for advice ........
dont worry richard am shifting to o2 exec

Phone freezes up when idle

If I leave my phone on and come back to in about an hour it becomes unresponsive. The screen is won't come on, usb won't work and the power button doesn't work as well, but the lights still flash. All I can do is take the battery out and turn it on again.
At first i thought the keypad must have been getting disabled after a certain amount of time for some reason, but since the usb the connection alos dies when it's idle it must be something else.
I've been having this problem for awhile now. It first it started every once and awhile, but now it's getting to the point that I have to reset it every hour or so.
I just upgraded my ROM to Kavana 080408, but I've had this problem running the T-mobile WM6 ROM as well, therefore I'm guessing it's a hardware issue?
Any thoughts, questions, or help is greatly appriciated!

call tmobile and ask them to send you a new phone... its hardware issues...

Thank you. Err.. the only thing I haven't mentioned (for lack of mistaking the problem) is that just 3 days ago I dropped my phone outside and it rained the next morning. When I recovered the phone it was soaked.. I let it dry out and it worked again.
I think the incedent had to have been irrelevant, because I have been having this problem for about 8 months regaurdless, just not as severe.
Would T-mobile be able to know it got wet at some point and not exchange it because they'd assume the problem was due to water damage?

Well if you look under the battery to the right where the sim card goes, there is a litmus paper that turns purple/pink when wet and its white originally. I would just remove the paper if it is purple/pink and try to cut and glue a white piece of paper the same size. And then I would call them and tell them.

Glue and fish strips?
Thanks, but hmm.. how exact should this be? I was thinking about going to the fish store and buying some test strips and using those. Then i was thinking about thinning out some glue and using that to stick it. Does this sound good? I'll post how it goes.

Dash Arrived then Died
I just got my dash about two weeks ago. Before I could start finding my way around, it began acting strangely. It would not respond and sometimes suddenly cut off on it's on. Then it got to the point where it would not turn on right away. I would have to play with it (battery and SIM removal) and then it might turn on. I thought I was using the power button incorrectly.
Finally, the dash would not turn on at all. Since it was new and insured I requested a replacement. T-Mobile insisted that I test it with a alternate battery (I had a charger stand + battery on order but it had not arrived yet.) Since it would still not turn on via USB or power adapter (no charging lights either) I was certain it was not the battery. After arguing with a T-Mobile Rep and Supervisor I finally decided to lie (er um exaggerate) and tell them I had tested an alternate battery.
Before the new phone arrived the charger and spare battery arrived. I tried both batteries in the new phone with no problems.
You may want to try and get a new phone but the T-Mo rep definitely asked me the color of the paper strip inside the battery housing. My rep told me that it would change color if the LCD was damaged or cracked but I checked another phone (Samsung T409 and Motorola V188) and based on the locations of the strips I would assume it's a water damage test strip.
You may also want to see it you can remove a strip from an older phone.
Good luck!

Dash Randomly Shutting off

Semi-Random shut off
I've been experiencing some random shut off with my TMo Dash. What happens is when I'm just doing random things or whatever, the whole phone shuts off like I pulled out the battery. There seems to be some correlation to when I use the wifi too. The rom has been changed from the original TMo rom > 1.33 > Rogers > 6.1. Anyone think they can offer some insight as to what is wrong and how to fix it?

I flashed from TMo official 6.0 straight to Kavana's 6.1 0307. This rom is rock solid, much smoother operation and better signal. I guess your issue is a isolated case. Maybe you can try to flash to TMo 6.0, then to Kavana's 6.1?

I had those problem since the 1.33 upgrade.
I learned that this happens when power consumption is high, like when I'm downloadind e-mail, during wi-fi session.
It doesn't happen if the phone is connected to a power source.
May be the problem is the battery (hardware), or may be is the power management section.
I am waiting a new battery and I am trying in the mean time to have it fully charged (and discharged) for a couple of cycles with this (kavana's) new rom

yea i kinda noticed the whole high power consumption/wifi thing. Hopefully its "just" that or "just" a battery. If it turns out to be the phone thats bad, time to upgrade to a touch or an iphone or something.

quick update. I just downloaded 1.22 which is the latest rom available from Tmobile. Install went perfect. Working within it seemed fine. Got online found Google Maps Mobile, and was able to download it and install it. Went back online to try to get the surreal unlock and thats when it died again. Quite depressing this is as I do like this phone.

yea this is happening to me since i flashed my phone like a couple of times ago, i dont remember which version tho. it would b sweet if someone figured out what the problem is...

From what I am reading on board posts, and talking to people personally, it sounds like a bad battery issue. Something along the lines of overcharging. In anycase, a new battery off ebay or your favorite retailer for $10-20 bucks is a small price to pay to trouble shoot a $100-200 dollar phone.

Thats what i found out last night, my friend also has an excalibur and i used his battery and i dont have any problems whatsoever with it. The most common occurrence of the phone randomly shutting off was when i was using EDGE, because i rarely use wifi but it did do it then as well...

I think that's it. I had the same problem with my battery. I couldn't even answer myphone without it going off. I sent my phone in to T-Mobile and they sent me a new one and I was having the same problem. I paid $110 for no reason (they said my phone had water damage). Don't pay for it unless you have to. Go to a T-Mobile cooperate location and ask them if they can exchange your battery for you. They should bring you out a free one. If not then I guess you can order one for $30 through customer service. It's probably just a batter problem. If you can get a free one then take it. And you have to use a T-Mobile approved charger. None of that third party stuff Don't do anything new to your phone yet.

I had this issue also until I bit the bullet and upgraded the battery from a 750 mAh to a 2400 mAh from AccessoryOne.com (BTW that company was sketchy, made me wait 2 weeks before I got the battery; made me pretty nervous.)
The new battery came with a new back door for the phone bc it is 3x as thick.
Works like a charm, runs for days and days without a charge.

...and we are back to the suck. Now it shuts down with what I know is a full charge doing all kinds of stuff. Checking email on the exchange server, surfing the web, checking voicemail, etc.

Glad it's not just me. I posted about this after the 1.33 update and everyone made me feel stupid, like I couldn't tell my battery life had been cripled recently. My symptoms are the same, phone shutting off randomly, especially on wifi. Its now at the point that my battery is not holding a charge more than 5 minutes after being plugged in all night. I have actually noticed a bulging of the battery and the back cover will not sit flush any longer. Today I went to a tmobile store and they replaced the battery with a brand new unit, but it still shuts off when wifi is powered on.
I really like this phone, help?

It's a battery issue.. I had Tmo send a replacement phone, I swapped my battery over and beat on the new one for 30 seconds with the Tmo ROM and it shuts off..
Theres someone on ebay selling OEM batteries for something like $0.99 + $5.60 shipping. I got one on the way now.

Tmo told me to eat s*** when I asked them to replace my battery and threw me off to HTC who also told me to pound sand because HTC doesn't have a contract with Tmo.

I really hope that works for you but I think I am done with this phone. It started after about a year with the old T-Mobile Windows 6 system. Wouldn't haold a charge anymore, shut off randomly. Thought it was the battery. Bought a new big fat battery 2400 mAh, changed to WM 6.1 Kavana and the issues are still there.
Sorry HTC, this is a piece of crap. With all the bells and whistles and internet crap it really doesn't matter much if I can't make a F**KING PHONE CALL!!!!
I am going back to Nokia and as long as it supports Exchange server so I can work I am good because first and foremost I need the PHONE to work so I can TALK to people!!!

Just jumping on the battery bandwagon ... I had similar problems that were resolved by replacing the battery. A new battery + new 6.1 ROM = new phone!

I've had this issue. For me, I was draining the battery by checking for new emails every 15 minutes. Wi-Fi can also be a power hog.

Dash intermittent powers off??
Here's the situation, my original ROM was T-Mo wm 6.0. While using this ROM, the phone would occasionally lock up...I had to remove the battery to clear it up, but after that all was fine. Then I upgraded to wm 6.1 kavana...initially, all worked well, ran it for 3 months no issues. Lately it just powers off, when I power back on, it will look like it's regular bootup, but just as it registers to the t-mo network, it will power off again. Even after removing the battery for a few minutes, I might get the same results...eventually, it will work again. So I thought maybe all the apps I have running in the background could be causing this. So I upgraded to rickywyatt v21. Even without installing and running my normal set of apps ("Don't Forget", "Keylock") it still powers off intermittently and behaves the same way. What is causing this and what is a fix?

Battery or Omap Clock ?
If you are using the overclock (omap clock) feature of rickys rom first disable that and if the problem still occurs get a new battery. I had the same problem and doing that I now have no random shut down issues. Im pretty sure my battery was shot.

TP2 Switching off when closing keyboard

this is a strange one, when i slide out the keyboard out it works fine, but sometimes when i "close" the keyboard away it switches off the phone completly. initially i thought it was software, as i was playing around with some files/settings that mucked the phone up bluetooth wouldnt wwork, nor gps and the phone ran very slow, so i thought i'd upgrade to htcs official 6.5 rom on their webiste (last weekend) and the problem is still there. so i assume its hardware, but i dont understand how. it doesnt matter what program im in it will sometimes just switch the phone off, if im sending a message it doesnt have time to send and its not saved in outbox or draft.
if i close the screen really slowly, slower than the springs want to it seems to not switch off as often.
the phone is an unbranded TP2 bought in august 2009 with the HTCS unmolested 6.1 rom originally.
i dont want to send it off for repair if i dont have to, but have you guys got any ideas

Does the phone completely turn off or just suspend? If it turns off completely it is definitely a hardware issue.

i have that happen too, usually after I switch batteries, so I figured its a hardware thing. Battery losing connection when being jarred by closing I guess? so I tried putting a folded small piece of paper under the battery door to hold the battery firmly there, seems to work so far...

I haven't had the issue happen to me, but I've seen a number of posts around here where TP2 owners have had that issue and the solution that worked for several of them was to wedge something under the cover to hold the batt tightly in place...apparently on some models there's just enough wiggle room for it to break the connection and shut the phone off when there's sudden sharp movement, like the slide-close causes.

never thought of the battery, i'll try that cheers

Note 3 powering off by itself

Hello, I would like to start off by saying I'm new here AND in Android culture. I was an iPhone user, but decided to swith to something different. Since I live in Europe (in Lithuania, to be exact) I figured that it wouldn't mean anything here if I bough a blacklisted T-mobile Note 3 4G LTE phone. Now to the main point - I got the phone yesterday and noticed something suspicious. Firstly, it came with aftermarket charger and usb cable (not usb 3.0, just a simple micro-usb to usb 2.0). My first problem is that when I am charging Note while it's on, it almost doesn't charge at all. Only when I turn off the phone I can expect the phone to charge to 80-90 percent in 8 HOURS! That's insane! Needless to say, I WILL be getting original samsung charger... Now other complaint is that the area around camera gets hot even when changing settings. Not really sure what causes that, so I did 4 factory resets yesterday.... Today it gets warm, but nothing suspicous. Disabled KNOX and other crappy programs. Not sure if it's the chargers fault, but battery life sucks. Phone drains the battery like crazy, the percentage drops about 1 in minute or so. When I use the power saving, reduce the brightness, use airplane mode, it's better, but even If i charge it and use my phone at the same time, the battery percentage still keeps going down
Now, the biggest wtf moment is when the phone is not plugged to charge, if i press the sleep button, the display turns black and after a few second the phone shuts itself off. No sounds, no vibration or notifications, it just silently goes to sleep. I can only turn it on again. I could even successfuly unlock the phone to use with a sim card, the phone is also making fun of me! Not really sure what's happening with my note that i bought off ebay and spent quite the amount of money, but I am starting to get into depression...
Please, if anyone has ANY idea what the hell is happening (apart the stupid charger), i would really appreciate any answers. And sorry for the long post and my english, as it is not my native language!

Could be a counterfeit - Check the serial with Samsung and make sure it has all the crazy samsung sensor, the counterfeits usually don't
Make sure the power button isn't sticking, I had an iphone 4s that did the same thing and it was due to power button hardware problem.
For the charger just get a cheap one off ebay with the right power ratings(find them for your country on samsung.com) and I find Toshiba sells replacement USB3 cables for their hard drives really cheap - That can save you 30$
Blacklisted IMEI phones are a gamble, if you can prove it's a counterfeit then ebay should refund you but it might also be a phone some bad man/woman/other stole and might have been abused. If it's the latter then that's a shame that he ended up stealing from two people...

Thank you for your answer
Well, the power button isn't sticking, I can clearly feel and heal it click when I am pressing it. The IMEI under the battery matches the IMEI in android system settings. I checked my IMEI on swappa and it says that phone was reported stolen (yay..). On imei.info site it says a different model (n9005 instead of n900t), but whatever.
Thank you for the info about toshiba usb 3.0 cables, might as well buy one right away
To be honest, I feel like it's a faulty item (even though seller assured my that the phone is working like new and that he replaced the battery). The battery life, as I said, is terrible, it doesn't hold a charge, the vibration motor seems very cheap (it's too strong, it sounds very strange), speaker seems to be not-ok too (distorted sound not even on full volume), screen-capture with palm doesn't even seem to work properly, I can't choose various music eq's (it says that this eq is not supported with speaker), I can't get my sim to work with this phone. Well, according to the ebay ad, phone should be working properly without any problems. The fact that the battery or charging mechanism sucks determined that was a lie...
Now I'm wondering if this info would be enough for paypal to refund me, because the phone is almost unsable (with self shutting of while it's not charging) and sad battery life...

Sorry for double post, but I noticed something very strange...
Well, turns out, that when the airplane mode is off, the phone gets very hot around the camera and battery is draining like mad. BUT, when I turn on the airplane mode, note cools off, battery still keeps draining, but it seems that not as much... Anyways, is it possible that the cellular module or something like that could be a cause of all my problems? (and to keep in mind that I haven't been able to use any sim with it, as it keeps saying "searching")

Sim won't work unless it's unlocked.
My suggestions are to:
1. Stock restore and then root the device.
2. Just sign in to phone using WiFi and download chain fires region lock away. Roughly $3 US.
3. Then try out Sim card, see if you can get signal.
If you can get that far, it will tell us what other kind of problems the phone is having on its own. Sounds to me at the moment it is trying very hard to find the signal and causing battery drain issues. The random shut downs could be due to the phone over heading and shutting down as a fail safe.

I did everything exactly as mentioned in the thread that you've posted the link to. First of all, booting logo changed, then my phone became unlocked (when I inserted the SIM, it didn't ask for unlock code). However, even with apn settings, it still says "searching" and gets quite hot in the upper-left side of the phone (when screen is facing towards me). I was really hoping this would help, but it didn't do much, as it seems... Anyways, I appreciate your good deed trying to help me I'm really desperate to make this phone work with my phone, but can't seem to manage to do that, which is very sad...
