I have a very annoyeing problem, my cruise stop accepting charge the led is lighting and the status when i plug it into power is charging but nothing happen,or it charge and empty the 100 % in 10 min , i bougt the device from uk and the local agent refuse to check it ,ofcoyrse i am not using the offical rom plz plz plz advice me what to do
The first thing i'd check is the charger. Try using a PC to charge the Polaris instead of the charger you are currently using. If it works, get a new charger.
Next thing, i don't know what part of ROM is responsible for the charging circuit control, but i would try & look it up on the forum, and reflash that part of ROM with the original.
And just in case everything else fails, i would start messing with the circuitry, but i would really hope it doesn't get to that, cause today's electronic is really hard to fix, with all those 10++ layers PCB's, BGA chips, hardly identifiable SMD components, etc etc.
Thank you very much for your reply,te problem is i tried all you mention and the problem still the same any advice now?
Try cleaning the the battery contacts, the battery connector contacts and the USB connector contacts. Try replacing the battery with another one, if possible (preferably a 100% working one, for example, try swapping batteries with a friend, just to see if the battery is causing the problem).
And, sorry to disappoint you, but HTC build quality is quite bad, hence, it can easily be a hardware problem. In this case you only have 2 options. Get it to a repair shop/lab or open it up and mess with it yourself. Can't really help you with either, sorry.

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 ;-)

I am using Samsung Galaxy S2 unrooted (bought in India). The phone behaved properly for 2 weeks and then started giving these issues.
1. Switching Off does not really switch-off the phone. A battery symbol comes similar to the one that comes if you are charging once the phone is switched-off. However, there is also an exclamation mark (more like a thermometer) which blinks. There is no charger or USB connected.
From the above state, you cannot switch - off / on the phone unless you plug in the power adapter / USB.
2. I have noticed that while that even when USB Charger is attached, the Battery Status (Menu-> Settings-> About Phone->Status) shows "Charging(AC)".
3. A related problem to the above may be the fact that "Samsung Kies" does not start when you plug in the USB cable with the computer. The phone does not even connect to the computer via USB mode (allowing USB debugging). I have re-installed Kies / USB connectivity drivers for my PC (Win XP) a couple of times and see no change in the behaviour.
4. When charging is removed, the battery health using Z-Device Test (3rd party software) shows "Over Voltage".
I am not sure if anybody else has seen similar problems. Appreciate any help.
I have exactly the same problem. I will go with my SGS2 at the warranty this week.
Me too having same problem... Guyzzz please help us...
please do reply..
Please give some solution to the problem..
Same freaking problem here...
the battery doesnt even charge full.. it goes up to 70% and shows its completely charged..
then it drains fast too..
someone please find a hardware or software DIY fix for it...
Same problem here... I can't believe this is happening after less than a month of buying it.
I've been reading through different forums and some people got it fixed by cleaning the usb port:
go to androidforums and paste this in the URL.
samsung-galaxy-s2-international/377331-spurious-battery-temperature-warning-2.html
xdadevelopers won't let me post url's since I'm still too much of a n00b.
Here is a quote from the forum if the link does not work:
Anybody still having difficulties with this and finding this thread, go down the clean-it-yourself route. Worked for me. You will need: some isopropyl alcohol (disk cleaner), wooden toothpicks, some compressed air.
First things, remove the battery, sd and sim card.
Soak the tips of a couple of toothpicks in the isopropyl. then use them to carefully scrape the top 'tongue' in the port, the bit nearest the screen. you'll notice the toothpick gets quite dirty. Do this a few times with fresh toothpicks (or cut ff the dirty bit with sharp scissors).
Once the toothpicks aren't getting dirty any more, gently ease the tongue up, towards the screen a little, don't force it too much.
Use the compressed air to give it a good blow and leave it to dry for a while.
Its solved my problems, Battery Monitor Widget recognises that the usb is unplugged properly and no more warning triangles or poor battery performance. The phone, also gained an extra 20% of battery out of it.

I hope this helps someone else, mine is still not working.
Update:
I've been constantly cleaning the USB port very carefully. Behavior has changed in several ways. The port is still acting crazy, sometimes if I turn it off, the phone will boot up by itself, BUT...
I had it recognized by my laptop a couple of minutes ago and able to move files from and into it. Just as if everything was fine.
It came down again because of the crazy behavior of the port.
I would undoubtedly say that this is a hardware issue. I'll go buy some pressured air today to blow the port and make sure it's clean and dry.
Had the exact same issue
In Addition to battery drain, unexpected MTP app pop apps with USB connecting sound (that could go on and on for minutes). and not being able to connect USB mass storage (PC complains on device malfunction...)
After reading quite a lot forums I found out that this is a well known issue (at least for the users). I called samsung they didn't want to take any liability for the issue, and even worse they said my device is non-US device, thus I can't get support even if I wanted to pay for it.
I figured it is a HW issue, and did a little study on what replacement part are being sold on the market, short analysis showed display (well that is true for most devices, cause we tend to break them, ain't we?) and USB PCB. the latest matched my suspicion on USB HW defect. I bought the PCB for 7$ replaced it and tadam: that fixed my phone.
Samsung should check themselves, people pay 600$ for the device, if there is a manufacturing issue, they should recall and fix, just like big companies do, just like Intel did with Pentium and just like Toyota did with braking systems. nevertheless they should find an arrangement to give their customers service anytime everywhere! or better make their products not requiring service
and the problem is...
i have the exact same issue, and when i contacted samsung about it not only they did not took any liability on this matter, but they said that the warranty was voided because they found sodium residue on the usb port at the bottom of the phone, and for those of you who do no know sodium = salt = sweat, so according to samsung i voided the warranty on my gs2 because my hands sweat. not only is this complete nonsense because it is an exposed micro usb port but because this will be in contact with sweaty hands when you are holding the phone in landscape mode, so after i did some research about this problem i found that the issue is not only that the usb port is exposed but that the usb flexor and the port that it connects to are very lo quality cooper(which should be gold plated) and can very easily have corrosion problems, so the solution is to clean the usb port if detected early, but if you have been having the issue for a long time like me you need to change the usb port, flexor and the port that the flexor connects aka "the usb chip", as well as the battery since having over voltage on a battery for an extended period of time can ruin it.
Hi All XDA Members I have a problem with my new phone (HTC Desire S) and was wondering if anyone could help me with what might be causing a certain charging problem, soo the problem...
The phone seems to think its being charged sometimes even when disconnected and is failing to charge the phones batteries through the standard wall charger or USB connection, therefore I am having to charge the batteries via taking the battery out of the phone and charging it in a separate dock I have purchased.
Sometimes as well after charging the batteries in the dock then placing them into the phone and turning it on the phones LED orange indicator glows and still thinks its being charged even when it has had a battery unpresent in it for several hours?
Does anyone have any possible outcomes to what this may be because of? Any help would be much appreciated?
The phone is running MIUI Android custom ROM with s-off.
Thanks,
Daniel
NOTE: I know I said "my new phone" but it is second hand and I purchased it with this problem hoping to come up with a fix.
have you tried other roms and experienced the same problem? or have u only ever had miui on it?
Hi, cheers for the quick response, and no I have tried multiple roms so far and all same problem.
Could it be anything to do with me getting cheap replaceable batteries for the phone as they are also not at the standard 1400mah but at 1450mah or should this not make a difference?
Cheers

this could certainly be the issue! so your saying it doesn't have a original htc battery? if i was you, the 1st thing id do is try a genuine 1. try to borrow 1 if u can from a friend or drop into a phone shop and ask. If it doesnt solve the issue atleast u havn't blown 30 quid on an original battery
you should try a genuine battery for sure! also their capacity is 1450mAh not 1400
check amazon uk

Just discovered guys that the batteries are actually 1500mah? Is this the problem and is their anyway to configure the phone to run with these batteries properly?
I am beginning to think whether it could be because of previous water damage if it has suffered from it before, but I would not know or be able to find out myself if it has been water damaged.
I was also thinking it could be this as maybe a possible short it happening on the main board and is causing the phone to think its constantly charging? Maybe?
Cheers Guys!
Can anyone help pleaseee!!

What makes you say that the battery is 1500 ? It's 1450.
HTC's own website says
Code:
[B]Power & Battery[/B]
Battery type:Rechargeable Lithium-ion battery
Capacity:1450 mAh
Hey guys (apologies I see this is a month old)
The issue Lowery91 has seems to be exactly the same as I had with my desire s. I'm breaking my heart trying to find out what's going on.
I have one of the original batteries that came with the desire S. The phone has these issues without being rooted (which I intend to do to see if I can amend it).
However for me it first started acting strange when I plugged it into a car charger.
Again sorry for rehashing this post but if anyone could shed some light on this I'd really appreciate it.

I'd suggest that you contact HTC support and get them to send you a replacement battery, explaining that yours is faulty, don't send your existing one back.
Swyped from my Desire S using XDA Premium
i think it is not a battery problem, i have two htc desire S and one today had the same problem, i tried to change batteries but when i put battery from other desire S i had the same problem, booth batteries working perfectly on second phone.
So i think it is phone problem. Something like voltage loss or etc. Because i thinkphone gets not enouth power to charge battery. But this is only my opinion.

Check this: It was a small pin inside that had come out. It connects the USB to the motherboard and is visible just below the battery. I fixed it in 10 mins with a bit of R&D. Now that you know, it will take you less than 10 seconds.
Having opened up the phone quite a few times now, hopefully i can give a couple of pointers towards this...
There is a small connector with flex cable that connects the USB port to the main board of the phone. To get to this easily, remove the batter, SIM and memory card. Also remove the 4 torx screws at the bottom of the phone and gently slide out the plastic clip that holds the battery in place. You will see this connector at the right side of the phone if its facing down. Just push it up with a small screwdriver and push it in on the connector again. Reassemble.
Hopefully this is the cause of the problem in the first case! Please do this with care..
Disclaimer: I am not responsible for bricked phones/broken usb ports, etc. Please do this systematically and all should be fine.
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.
Hello!
I thought maybe someone with more knowledge about electronica can maybe suggest what i can do with this very small problem..
I was repairing an acer aconia one 10.They told me it charged, screen showed that..But the battery drained instead it charged.
I thought maybe something with the usb port, it looked loose.Opened tablet and after i lifted the motherboard i saw indeed one points of the usb housing was loss.But contact points/pins where good.But in the case itself there was a very small square block, what supposed to be connecting d-/d+.
It is in good condition but i cant figure out any more what side supposed to be where.All the contact points are good, came loose from the board but i don't have a ''footprint'' any more..
I read a lot yesterday if i first could discover what it is and what it does.It seems to be doing something what triggers maybe the charging in an higher current.Without it, so with loose D-/D+ i read somewhere it then cannot talk how to charge the tablet, and could even drain the battery...
And that D-/D+ gets short cut to trigger that.
My question is, this little thing must have an front and back i think, but how to see that.Tablet works with another battery..But how to fix this charging problem, what would you guys suggest.I can solder it back, what's the risk.Or solution to trigger the charging, i asked them and they dont need an working usb port, as long it can charge it.Shortcut it, ...I dont know..
Here an vid where you could see the small component behind the usb port.
