Hmmm, this is a weird one guys.
I can charge my X10 only if it is plugged in to the USB port via the computer. However, when it is plugged directly into the power socket, it does not charge. Now, I've tried two different chargers, and both work when charging another device (my iPod Touch).
I don't understand. The cord can't be broken, since it works when charging from my computer? Yet, the charger (the thing that plugs into the wall) can't be broken either, since another charger didn't work and also both have the ability to charge my iPod.
What's up? :S
Thanks in advance.
NOTE: Even when charging while off works on the computer, just not when it's plugged in (and I am not using a custom kernel either). I doubt the ROM matters (since it still has the above problem while charging when off), but even so, I'm using v061 of Wolfbreak's 6.1.3 ROM.
Bump bump, bump it up!
Do you use the original SE in-wall charger? If not, thats the problem, if yes I recomend to test with a different wall charger (eg. from another device)
May be the cable it faulty? Because the PC charging uses a less amount of Volts (to my knowledge) and the charging while connected to PC is very slow. Did you try with any other Official cable?
It could possibly be your cable as mine broke a few weeks back (Same Problem), I just replaced the cable now its fine
Guys :-/
Went out and bought a new cable, and still not charging from the power Only from the slower laptop USB port :'(
I think it may be the X10 itself..
I am still suffering from this problem And sometimes when it's connected to the PC and displays 'charging', it instead discharges

Maybe the connector in the phone is broken????
Yep your usb port is broken, mine did exactly the same thing. You will have to send it to fonebiz in rockdale, nsw. I just got my phone back, took 6 weeks to repair!

Rockdale? 6 weeks?! Not going that far. :-/ I can live with just charging from the PC at the moment.
Thanks though Sad news indeed
Is is still under warranty? It will eventually stop charging from the PC too. I was waiting for parts to arrive so maybe they have them in stock now. That was 6 weeks from melbourne and back.
Going through the same thing in the US. I was told repair would be 5-7 days, but I'm sure I'm looking longer. If it comes back within the time frame they gave me I will be pleasantly surprised. I hope you're still under warranty and do your self the favor and send it in or soon you will have a very expensive paper weight. Good Luck!
I went through the exaxt same thing. It stopped charging from the wall but could only charge from computer but eventually stopped charging altogether.
Did you try taking out the battery and plugging in with the original se microusb cabe to the wall. After 5 min. put the battery in. First time didnt work for me but then i took out the battery again and put it back in immediately and then it turned on.
try getting a usb-to-wall charger, and plugging your computer usb cable into wall.

Out of curiosity, how long before each of your X10's stopped charging altogether? :S
Because, for me, it's been longer than two months and throughout that time I've managed to keep charging it via the computer.
Thanks.

I've 3 usb-to- chargers here:
From a MP20 phone, generic charger that can't charge my phone and also can't charge most of other devices, output power and voltage are low.
From an old Ipaq(not ipad) it does charge my x10 for some reason takes longer than the original, it says on it 1000mA and 5V, I don't remember the real amp and voltage on it.
And the original one, always charge really fast(2 hours for a full 0 to 100% when the phone is ON)
Conclusion, buy and original charger if you not using one, which seems to be the case.
OR, update your baseband if possible, as battery issues are normally related to baseband are normally the cause of this errors.
To make sure you can always try to do a SEUS repair.

Sorry to say this, but your are wrong man.
My charger says 5.0V which is exact the same voltage as any USB ports(exception for some internal USB ports used commonly for bluetooth and other low consumption devices that use 3.0 to 3.3V).
The difference is mainly on the amount of power amp it can supply, the original usb cable + wall charger provides 700mA, while in the PC USB 2.0 ports provide 500mA, 1.0 USB provide 100mA and 1.1 I don't remember now, generic usb wall chargers say sometimes they provide 500mA but they mostly provide 30l0mA and sometimes they do not provide on 5.0V they oscillate between 4.6 to 5.2V a good usb port have to provide 4.95V to 5.1V any difference from this may even burn a phone if higher and not charge or reduce a battery life if too lower.
Everytime a battery is not charged up the end of 100% they battery life gets a bit reduce as next time even if you leave it to charge up to 100% it won't really be at 100%, this can only be seen by measuring the battery voltage after the charge, fully charge it must reach up to 4.7V
on the battery or something like this.

If the cable is too thin(like 1.0 usb cables they can't handle 500mA if connected to an already extended usb port it may not get recognized and also not even charge.
Laptops usb ports may not allow 500mA it different for every laptop, some work, some doesn't and others your have to set that on bios.

Always when connected to the PC it should say charging, if it did say discharging at some point then there was something wrong.
But charging on the pc is very slow and not good.

Just use a miniUSB cable and plug it into your computer. Any USB wall charger should work. I've used iPhone USB chragers with a miniUSB cable, Nikon camera chargers, as well as a Motorola one. You just need to plug it into any USB port either on a wall or on your computer. Leave the device off while it charges overnight.
Problem with charged
I use both ways but no result , phone indicates to charged but battery not charging.Charger is original and consists of two parts: the charger and mini usb cable .When i run it sometimes on the displays show this message : The charging current is not enough for device power consumption.Please shut down unused applications , or switch to AC adapter. And I do not use any applications. I tried to load phone in the off position , indicates that the charger is ON but the battery is not charging .Please help if someone has the same problem

Try it with a different miniUSB cable. If you don't have one handy, miniUSB cables go for pennies on Amazon or eBay. You can find them in retail stores for about 10 dollars or so as well. If the cable isn't the problem, then it is either a problem with the charge port on the device, or the battery. It's far cheaper to trouble shoot the cable, so let's just start with that.
Sound like the charger is insufficient power, even though it says 1A. Try charging from a computer USB port and see if it charges. HTC don't list TP2 as suitable for this charger.
I am also facing same problem. LED shows charging but phone does not charge. And when I insert charger "USB TO PC" page shows up, Like I have connected the phone to PC.
Please Help...
I just had an issue charging which turned out to be an easy fix.
The led would come on and the icon would show charging but it wasn't increasing the battery %. Then I would get a message about the power not being enough and to plug it into a charger. I tried several chargers and was getting the same thing happening. I blew a few puffs into the charging port which looked clean and it was still happening. I wiggled the cable/plug in the port and occassionally the charging light would go on and off. The charging led even started to go on and off with the phone just sitting still on my table. I feared that my charging port had gone bad so I ordered 2 spare batteries and battery charger from ebay for $10 (works well and battery life good).
While waiting for the ebay purchase to arrive I did some reading up and saw that pins could be bent etc. In my fustration I used a pair of tweezers to gently scrape the charging port pins/contacts (in a straight direction). Then I used an old toothbrush and firmly brushed out the usb port - a whole bunch of lint and stuff come out of the port even though it had previously looked clean.
I plugged in my charger and bingo! My charging issue was gone.

That was the biggest problem with MiniUSB was the width and height of those ports. It's a haven for stray dust and dirt. They need to be brushed out every so often, especially when you just drop it in you pocket.
hi buy and it schould work
buy a new charging cable

I was facing the same charging problem and was looking for a solution. And i found this forum and read it and did the same thing and my problem is fix.. I can charge my mobile now. Thanks a lot for the great help.

All of these dumb charges, ie bricks in the wall, use the unused USB pins to communicate how much power they can provide. There are some resistors they put on the D-/D+ to say this is a 700ma charger or whatever. Trouble is that there are limited standards on these resistors so it's more than possible that a phone will charge but not enter high current charging when attached to a new brick in the wall. The cables however are more universal.

there have been other threads about this. usually its the charger overheating and putting it in a ziplock in the freezer, resets it.
Mine did that too, just leave the charger and everything unplugged from the wall for a day. That fixed mine.
Sent from my ADR6425LVW using XDA Premium.
The other issue I've seen is poor contact in the USB socket on the wall adapter. I had to unplug the usb cable from the wall adapter. Then, look at the usb socket on the power adapter. The gold pins are the usb contacts. Directly opposite of them, there should be two silver prongs. I had to use a small flat blade screwdriver to pry both of them out a little further to ensure they did their job of firmly pushing the usb cable against the socket's usb contacts. Once I did, my TF201 was able to get charge from it, again.
If you decide to replace the wall charger, I believe Fry's and Office Depot stock the asus charger.
Same thing for me.. PC recognizes it as a media device, but will not charge with wall charger. Wall charger works with my HTC Phone, so it works.
I don't think it has anything to do with the latest update, since the Dock wont charge either, and there's no OS in that, right?
Just experienced this today. I have had it unplugged for about 10 hours now, we'll see if it charges.
I had the same issue few days after I got my prime. I connected my sgs to the charger and it worked. Then connected the prime and voila-works.

C1. There are some good suggestions here I need to try.
Wrap it in a towel and bang it against a table. That will fix it usually. Then get some pc heatsinks and some arctic silver adhesive and you can attach them to the charger to keep it from happening again.
The plug has two options, 5V (standard for USB?) and 15V. I used the plug on my old HTC phone (Ozone) and then plugged it back into my Prime and it worked. Thanks for the great tips guys.
Since the charger works in two modes, I wonder if some charges became confused and started dishing out 5V when they should be dishing out 15V. Thoughts?

Hi, I got the same problem. The charger indeed seems to be stuck in the 5V mode, since, when plugged in the tablet does get charged, even though it is not indicated, but very slowly. It is charging as if it is plugged in to a pc.
I tried plugging it into (old) phones, but I still can't seem to get it to switch back to the 15V mode.
The freezer didn't help either.
Any other suggestions?
I waited about 4-5 hours before plugging into my old phone. My other suggestion is to allow the phone to charge for a short bit (30 minutes) unplug and wait, then plug into your Prime.
I have a feeling that its a transistor toggle that isn't flipping at the correct voltage.
I've had the same problem yesterday. In my case the problem was with the charge socket on the keyboard itself. Some copper pins were deformed and that stopped the device charging. I took a magnifying glass(also for checking if any of the copper pins are bend) and a small tool to bend them back. After this it charged again. Hope this helps.
My charger suddenly stopped working from today. The Prime is detecting the connection as the screen turns ON but it is not charging. I charged my sensation using the same adapter and USB cable and it is working fine. Why can I not charge Prime via PC like phone? Is it possible? I am in India and not sure if the power adapter is easily available as Prime is not yet launched in India.
Kindly suggest.
Thanks in advance.
Hi,
I've started to have this problem today, plug it in and it does come up with the charge icon but it doesn't charge - or doesn't seem to.
However I left it connected last night from midnight until 8am this morning and it went from 13% to 17% so it is charging VERY VERY slowly although the unit doesn't actual seem to think it is.
I have it plugged in to my phone right now and its working perfectly, I borrowed the charger to my g/f last night to charge her iphone and i'm thinking this might have done something to flip the voltage as since then it isn't working.
Anyone have any ideas on this??

But if the charger works fine when charging a phone it cant be the connection at fault..
It does seem to me that the power it is outputting has dropped especially the I managed to gain 5% over the course of a night where WIFI was off and screen was off even though the charge icon doesn't come up.
Is there a way of forcing the charger back in to 12v mode??
damnit... I had the same problems a few days ago and I thought it was in the cable instead of the charger... not realising the charger has to put out 15v instead of 5v.
Does this mean the Transformer won't charge with for example, my HTC charger?
I totally messed up my cable, because I thought it was broken... when I opened up the USB plug, I noticed the yellow wire was not connected anymore, but this didn't solve anything. Eventually I messed up the cable that bad, that I've ordered a new one from ebay... but when I read this... I should have just banged the charger a few times... shait.

Does anyone know if there is an official 2m USB cable available in the UK? I bought a generic one off eBay, but it charges the phone extremely slowly....

Are you charging the phone from a USB port? If so, it's the limitation of the port, not the cable. Try with a proper charger an it should charge at a more sensible pace.

Charging speed doesn't depend on the cable but on the charger it is used with.

I'm afraid it doesn't work as well for me. I got a Kindle 3 cable, and while it does charge the phone (using the charger which came with the phone), it does it very slowly. So slowly that if I try to use the phone even for basic tasks whilst charging with it the battery still keeps heading south.
If I use the stupidly short cable that came with the phone it charges nice and quick, but every other cable I have used so far either doesn't charge or does so very slowly.
Any ideas as to why this would be?
On a related note, this sounds good, but again the cable looks stupidly short:

What are you using to charge your phone? An EP-800 or something else? I have a cheap 1500ma charger that seems to take ages to charge my Xperia. The cause was that for a full speed charge, pins 2 and 3 must be bridged. I dismantled the charger and put a tiny blob of solder on the usb port pins. It now charges like a demon.
Same story with my car charger. Before the mod I could actually lose charge when using satnav and streaming music over bluetooth.
I have a battery widget that says whether I am on AC charging or USB charging. Its name eludes me.
Oh, and a safer alternative may be to sacrifice a USB cable and bridge the pins on that.
Better than all those though is the official Blackberry Playbook charger. 2A and a long cable. Charges the phone like nothing else.
Yep, am using an EP-800.
Fortunately the latest cable I ordered works a treat, so I can happily recommend this one:

Hey, been on these forums for a while, I rarely ask for help (been pretty lucky with the phones), but I have a question.
My phone won't charge. Or rather, it requires a time consuming process of fiddling, unplugging, replugging, and sometimes minor surgery on the USB port with a toothbrush or a tool I've crafted out of a Q-tip. However, after a night of charging (or some interrupted equivalent that results in a charged battery) the battery quickly depletes while still plugged in.
This is most clearly illustrated when yesterday, at 8:45 I rolled over and checked my phone to see if it had been charged. Pleased to see that it had been charged up to 100% I fell back asleep. When I woke up again to go to school at 9:10, my phone was entirely dead. I couldn't even get it to turn on to the point where it showed the I9100 screen. After following the time consuming and frustrating process of fiddling with the USB port and Micro USB charger, I coaxed the phone to show the powered-down charging screen, where I left it to charge to full.
I have been experiencing this over the course of a few weeks and I have tried many chargers, but only one of them will work at all (Interestingly a Motorola cord). Upon inspection of the USB port, nothing seems out of the ordinary, though the 2 prongs on the outside of the USB port male receiver look slightly different than the inside 2, though they difference is symmetrical.
Does anybody have any idea of what could be plaguing my phone? USB or battery? This is my second SII, a replacement one after my original one was tragically lost in a hot tub . Any thoughts would be awesome.
Thanks

If you are using Siyah kernel have you altered the charging current through EsTweeks?
If so then it is possible that the battery / charging circuit has been damaged. Try resetting the values to default (I think its 700mV on AC and misc and 600mV on USB but dont quote me).
Failing that then some hardware trouble shooting (trying a new battery / external battery charger) will help you figure out what is going on.

My signature is quite outdated... Currently just running CM 10.1 with stock everything. Haven't tweaked anything in that capacity... but will try my other battery (if I can find it). Thanks!
I was having this same problem with my HTC vivid. I tried charging with may chargers, the phone claimed it was charging (orange light lit up) but the phones battery was dying while plugged in. Just like you said, the battery depleted rather quickly when plugged in. Since my phone refused to accept any form of charge I bought an external battery charger and some extra batteries.
However, last week I wondered if maybe there was some sort of dust, or small pieces of sand inside the Micro-USB port on my in my phone that were possibly "blocking" the charger from properly charging.
So I bought an air duster and blew air into the USB port of my phone. I guess there must have been something in there because that fixed my issue and now my phone charges!
Now I have 4 batteries for my phone and an external battery charger.
Try it on your phone, see if you have the same luck I had.

Maybe I'm missing something here because you seem to be experienced on this forum and understand about searching first.
Anyway, this sounds like the common USB problem that S2s have. It can be the jack or more typically, the flex cable. You replace the little board. Search for USB in this forum. I just changed mine with one I got on Ebay. Cheap and easy.
