My XDA II suddenly decided to think it's always charging, EVEN when it's not in the cardle. I don't know why. The upper right corner is always yellow (not flashing). The backlight brightness can only be controlled by the 'On Power' slider. Simply, it thinks it is in the cradle. No matter how I try, be it soft or hard reset, it's the same. In this siutaution, the battery drains VERY VERY QUICKLY.
In fact, this is the 3rd time I experience this. For the previous 2 occasions, I send it back to service centre and they change a new unit for me under warranty. But it's just 5 months and it has already happened for 3 times! It's hassle and I am thinking what I can do after warranty period.
Am I being alone and anyone else has experienced the same situation? Any means I can solve it by myself? Thanks a lot.
I have same help me now
I think this is from using the cradle, for some reason it distorts the pins in the phone and causes a short between pins. I found that using a usb cable makes this less likely to happen.
hm
this is happening to me too
i had to buy a new xda 2 .... i still have the old one , if anyone knows how to fix this i would apreciate it very much. ...
it is the same story, the led is always on, it always says charning even when is not... and the battery only stays charged for 3-4 hours.
I´ve the same problem since yesterday with my T-Mobile MDA², it´s Rom Version: 1.72.01GER (6 months in use without problems), Rom Date 03/16/04, Radio 1.17.00, Protocol 1337.28, ExtRom 1.72.170
The yellow light is always on and the batterie runs very fast out of energy (1-2 hours) and it´s always says charging and think it´s connected to AC power...
Possible fix to "always charging" problem
:idea: I got the same problem yesterday but I think I fixed it. (long rant)
By coincidence I was just finishing up after an upgrade to WM5 with Ramdisk when it happened. Of cource I suspected the upgrade to be the problem.
However, I remembered that I had gotten some snow onto the PDA exiting my car some hours previously, and started to suspect that this had created a short in the system somewhere.
Looking into the charge plug hole I could see that half og the bottom of the hole was covered with some light gray stuff. I used a thoothpick to gently scrape on it and lo and behold a big (relatively) wad of pocket lint came out. It had obviously become wet from the snow and created a short.
Everything works just like normal now. Charge stays fine (especially with my new 1700mAh eBay battery, recomended)
I have not had the problem return after the "fix". Fingers crossed.
I don't think everyone has exactly the same problem but I suspect it is caused by a slight short in the plug area in most cases.
Good luck!
In relation to this, when I sync my XDA II to my PC via the cradle, the phone automatically charges (even without the power supply). Is there a way to disable this charging feature? Cause the battery life will be shortened if charging happens when the battery is not drained first.
Thanks

My 2i does this as well, from what I have read this will not damage the battery. LiOn batteries prefer to be recharged before they get fully drained, in fact they like to be topped up rather then ran flat then fully charged. This is only going by what I have read on the internet, but it was on several differnt sites so I have no reason to think the info is duff.
Tx a lot for the confortable info.
@threadstarter:
the warranty should begin again if you receive a new device!
the warranty is on the device, not on the contract you have!
if you continue that way you should have a new one every half year ;-)

Hi, i'm searching forum for few days, and cannot find answer for my problem. On my Uni is Ranju 7.6, and all was ok.
Few days ago, when i was searching in TomTom, my Uni said, I had to replace battery or stack in recharge cable. I found, it happens when i'm doing somethimg memory intensive. For example playing Revival, using TomTom, or yesterday when browsing xda-dev. So battery appears "unknown battery" and all pda goes off.
I know, uni is checking battery every minute, but sometimes it cannot find battery... doesn't mattery if battery is full or not full.
Can it be hardware prob? I remamber, few days ago i fell off my bicycle, my uni was in case, in backsack, so nothing could happend to him, but maybe the shock?
Uni is too sensitive to shock, deeply sorry to say that ur Uni is having a series hardware problem. I had dropped my ex-uni from about 1 meter distance and even it has any apparent signs of the drop, even any minor scratch, but it lost its external speakers' sound and i had to change its main board.
oh But I saw my friend, who fell uni many times on floor, and nothing happend to it

it is somesort of luck, and the fact that the shock is transmited via the Uni case to the main board, and if it reached a weak point it will affect the IC related to that point. If the Uni is lucky, the force of shock may go to the case itself with microsocopic or visible cracks in nonfunctioal part.
Also, try another battery, may be the shock went to it, and assure that the second pin from upside is well conducted. In addition, try to clean the battery conducting plates and the uni conducting pins with alcohol.
thanks for advises, i'll try.

Also using Ranju's but 7.7. I never had this problem before with any rom. Just I bought a new clone battery, since then I always have this problem. it seems the infolithium is not working very well in this clone battery. I got used to it. Or just buy a new orginal battery. I don't care much about it I can live with it
The problem is the battery.
WM6 and 6.1 Roms and also later radio versions require more power for all of the various functions than the plain old wm5 roms.
Make sure that the battery is an original ( not a cheap Ebay clone)
It is also worth buying one that is slightly higher than the standard battery.
The problem occurs because the battery is unable to supply enough power in times of high demand.
I have had the same problem with old batteries too.
Also, it is advisable to flash a new rom with a full 100% battery charge.
Cheers,
Beasty
last year, i had an o2 exec, it fell off my pocket when i was riding my motorcycle. imagine the impact caused on my exec as it fell to the ground, rolling for a number of times, bumping almost all sides. luckily i placed it in the leather holster, only the corners are exposed thus having few scratches only.
after that incident, i notice that my screen had a stuck or shall i call it dead pixel. aside from this, all else are working. so i guess our universal is rather tough than what we expect it to be.
Hey mr,we do it in old fashion way
1. cover your battery with blanket
2. put it in the freezer
3. in over a night,you can dry it in the morning than,u charge it and you have a new batteries,its more cheaper than buying a new one

hey r u serious or just a jock?
some lucky - some not! i'm a part of un lucky man!
- trying freezer method
- trying empty battery method (batery indicator zero and device off it self, then resset till it won't on. Then charge it > 8 hours)
Now i'm buying the new one.
I woke up this morning and found my phone was mildly wet on the bottom. I slid open the keyboard to make sure it wasn't wet everywhere and it wasn't. After I dried off the bottom and started using it it began getting wet again. When I opened the battery cover to investigate I found the source of the liquid and immediately pulled the battery out. There is now discoloration on the battery and inside the battery hutch. The battery appears to have stopped leaking this liquid but it has only been an hour. I am obviously concerned that this has damaged my phone. The phone was working though when I checked my email and discovered it was wet.
When I researched it said Lithium ion batteries aren't supposed to leak but this is the only explanation I can come up with. The phone wasn't near water and since the top half of the phone wasn't wet, this must be the case.
Is my phone damaged?
Can I use the old battery from the TP2 (both batteries say RHO160 on them)?
Very strange. Can't you just swap it out at a Sprint location?
ummm get that switched out immediately. new battery, new phone, whatever...just get it taken care off. That ain't good at all.
I can't just go to a sprint store because I don't live in the US heh. My phone is unbranded so I'm waiting for HTC to respond.
The phone is still working fine but I'm using the battery from my TP2 and it's been working since early afternoon yesterday. I'm still worried it might start acting up though, fingers crossed.
I have 5 Arrives (five members of the family, each with their own......I really do like the phone). One of our phones gets excessively hot when charging via USB from a computer (but not when charging via the wall plug). How were you charging it?
Even still, I suspect there is some sort of power management issue in some of them phones.
I was charging from the wall plug, not from USB. The only time my phone gets warm is if I'm playing games on it for over an hour .
What happened to your battery mate. My phone also heats up a bit more these days and I am interested in what to expect.
Cheers,
Hi everyone.
Last night I went to bed and as usual I check my Nexus S battery.
It indicated me very low battery, and turn it off.
So far, no problem, i thought, well there isn't enough battery to turn on the phone. I connected the cellphone to the wall charger and went to sleep.
Today i woke up and try it to turn it on, the screens just flashes and nothing happens.... Removed battery, try it again, the same.
Try 100 times that, and there was one time a Warning of Bootloader came up. Don't know what i did different thought, but now i can't get the same result.
Actually now the screen doesn't even flashes when i press the power button.
The battery seems to be charged, i tested with a LED. My wall charger is also working cause it's able to charge my old phone.
And now to get things even worse, as i bought it in asia, i don't have warranty, and the gran finale, Nexus S is not been sold in Brazil due to some regulatory issues, so Samsung said it they can't help me with an imported product.
The Cellphone is brand new, doesn't have not even ONE month of use.
It's not rotted, and it was in the latest android firm.
Does anyone have any idea what can i do????
The phone doesn't respond to anything .
Tnks a lot in advance.
PROBLEM SOLVED!!! SEE THE LAST THREAD. BR!

Is it showing full bars when you connect the charger and press the volume button?
dude, i think there is something wrong with our country. take a look at this thread: http://forum.xda-developers.com/showthread.php?t=1111761
i think you tried everything possible, can't see what else you could do. Looks like a hardware issue..
if i were you, i'd claim for warranty, even if you bought in hk, it has warranty, of course you will lose shipping cost, but, it's better than lose the phone! =o]
good luck!
GchildT: Nothing happens when i connect the charger to the cellphone.
Already tried the hard reset (volumn up + power button) nothing happens
thiagodark: Tell me about it, i read this thread ealier this morning, actually i send it a private message asking him if he solve his problem... samsung is really disappoint me.
The thing i found most said is that the phone is bran new! Not a month year old.
And i didn't do anything, not even rotted, dropped, anything!
PROBLEM SOOOOOOOOOOOLVED!!!
The problem was that there was a little tiny piece of plastic dirt in the usb male plug in the phone! And that piece was able to make a faulty contact with the charger, the phone battery was dead as hell.
Can you believe that?????
I almost sent my phone across the world in order to use the warranty.
Now I'm back with my cellphone up , happy as hell!
Tnks a lot, and remenber to always clean everything before use more drastic measures.

My HTC Sensation seems to have a very strange power problem and I am hoping someone can help. Around four months ago my phone started switching itself off when I went to do something, it could be read a text, make a call or maybe send a text. What I noticed is when I turned the phone back on the battery level would jump down, it could “lose” 20-60% of its battery life.
If I then put it on charge it would never return to 100% unless I restarted it, it was almost as if the phone didn’t recognise the % of battery it had “lost”. This could happen many times a day and once it switched itself off around 15-20 times as I tried to make a phone call when hiking in the mountains.
The only time it keeps working is if it is connected to a power source. Also when it does switch off I notice it becomes quite hot at the bottom of the screen.
I swapped batteries with my girlfriend who has the Sensation XE and with her battery my phone worked fine but with my battery her touchscreen wasn’t as responsive as normal which was very strange.
I was running the HTC stock firmware but I moved to CyanogenMod to play with it and see if it was a software issue but the problem continues with CyanogenMod.
I spoke to HTC but they said I was out with my 12 month accessory warranty so I’d have to buy a new battery. The problem kept happening and it drove me round the bend for a while until I just decided I’d buy an Anker battery. I’ve had it for almost two months and all was going well until yesterday when my phone turned itself off as I tried to send a text.
Since then it must have turned itself off around 6 times either trying to make a call, read a text or send one.
Does anyone have any ideas? I thought it was just a dud battery at first but now with the exact same thing happening to the second one I wonder if it’s something else.
Thanks
try to put a piece of paper or something to fit where the battery connects with the device
maybe loses somehow the connection
best wishes
Hi Lsmith,
This issue seems to happen on many Sensation devices... but there is hope!
Sometimes it's due to a custom Rom or due to a let's say "faulty" connection between battery and the connectors of your device.
- I would first suggest to charge your phone up to 100% (if possible). After that, perform a reset (make a backup) and look how your device behaves.
- If you still detect the same behavior follow this thread ->
http://forum.xda-developers.com/showthread.php?t=1531232 (check out the last picture). This is the so called paper trick...
For me it's enough placing a folded paper on the battery itself, covering part of the sim card. Just try out what suits you best.
Cheers

Thanks guys, I'll take a look at that thread.
I have a TF101 that will not charge or power on. I rooted it a month ago and it was running great. My wife lost the charger and had plugged in the tablet USB cable to a cell-phone charger , I found plugged into a week later to the phone charger, unplugged and attempted to turn that tablet on, it flickered on for a moment and then died (loading screen) :silly: ya stupid right?. I them found the right charger and plugged in the tablet and the light indicating that it is charging does not come on. I look and looked online for help. I'm pretty sure its not a charging problem as I did the freezer trip on the charger box nothing, I bought a new charging cable and charger off Amazon, nothing. Still not coming on when plugged in or anything (That is why I don't think its just a battery issue from what I have read.) The connection on the tablet looks ok on the bottom and both the old and new charger will power up and charge the keyboard dock just fine. Has the tablet been bricked dead?? Nothing I can do??
Thanks for your help and reply on this your all awesome
P.S I also tried a slow charge through the usb port on my computer over night and left the tablet plugged into both chargers over the course of two different nights. No luck.Also can't get into (Apx mode) the volume up and power held down for 15 sec does nothing.
Looks like you're stuck. You'll have to make a decision whether to buy a new battery or not. A colleague of mine solved a similar issue with a new battery off ebay, but it doesn't mean there isn't another hardware issue.
When you say the charging light does not come on, you mean on the dock right? The tablet itself doesn't have one. Did you try to just charge the tablet without the dock? Did you try to open the dock and flip the switch?

Yes the charging light on the dock does come on I thought I saw what looked like a light on the tablet. So the dock is charging and working just fine.
A battery like this? (I would put the URL but its not letting me since I'm new.
I'm not super good would opening stuff up how hard would the battery be to replace? I did see a thread on opening the unit itself looked complex. Also Any more trouble shooting I should do? I may just buy a replacement off ebay and sale my old one. Also can you tell me if its bricked or not or whatnot? I just don't want to put out fifty bucks for a battery and not have it work
Well if it won't turn on, it's difficult to troubleshoot further. The general rule is: As long as you can get it in APX mode, it's not bricked; with hardware issues as the only exception. In theory, it should power on with an empty battery (and start the charging process), but I have no idea about a dead battery or how the unit is made to handle such cases. Give it some time I'm sure someone else here can answer that question from experience.
Replacing the tablet battery is not too hard, but it's a long task that requires patience and some tools. There's some videos on youtube and others about how to open the unit safely without damage, and decent tools are cheap assuming you don't have precision tools. By opening it you can troubleshoot it a little more. Inspect the battery for physical damage, like being oversized, which means it's likely dead. If it looks in good shape, try disconnecting and reconnecting it to the board; sometimes reseating a connector solves the issues. Also look for any obvious damage inside while you're there. Even if you don't know much about electronics, an obvious burn mark on the board is never a good sign.
If after all that it still won't power on, then yes you could check out ebay. Just make sure lots of people have bought the same from this buyer (the more the better) and they gave positive reviews for the product (stuff like "still works after a year"). Make sure it specifies it supports the tf101 and it should be fine.
Honestly from what you described in the original thread, I wouldn't be surprised if over-amp or something like that damaged the battery. Hopefully it's only the battery but as I explained, it's rather hard to troubleshoot. From personal experience developing boards like that, there are usually protections in the device to prevent damage in case of over/reverse voltage/amp. Depending where the battery is connected in the circuit sometimes it's protected sometimes it's not. I have no idea how Asus do it so take it with a grain of salt.
Can you provide said phone-charger specs? Volts/amps/exact model?
Edit: P.S. The device or dock will not charge through USB. You need the actual wall charger.

The phone charger that it was plugged into was a Galaxy S charger. 5v===0.7A. Doesn't seem high enough to have done anything...but I'm definitely no expert. (Literally)
Sounds like its a good idea to open it up then to check on the battery, if burned or oversized then I will buy a new one (As long as I don't see burnt marks) If the battery looks fine I'll try the reconnect. And cross hy fingers. Thanks for all your help so far. Any advice on where to buy the tools? Deal Extreme good for that Amazon?
No tools are required, ands its easy to get into just be carefull pulling the bezel off as the tabs that hold it on are quite weak (i broke a couple when i ripped mine apart in anger lol) after that their is about 10 normal screws until its open. It could be the case that the battery just needs to be unplugged and re-plugged in.
Its a strange problem you have there, the power output from that charger is less than half of what the standard asus charger outputs, if something is fried id call concidence as ive plugged my tf101 into various ac-usb adaptors with no troubles. Its a complete guess at this point but its almost like your tablet is suffering from the 0% issue thats common in the docks, where it refuses to charge if completely drained (afaik with the dock this is fixed by disconnecting and reconnecting the battery)
Also did you get an official asus charger as a replacement? a few of the cheaper ones dont even output enough voltage to fast charge the tf101.
