So, for the past couple of days I've run my battery pretty much dry, when I got to a charger it was at about 6-12% both times. What I've noticed is that my phone doesn't seem to charge from anything except the charger it came with (in the dock... now that I think of it, I should probably have tested that as well, so it isn't just shutting down USB when low on battery) when it is in this low-battery state, nor does it appear in ADB. I tried shutting the phone off and charging like that, but it didn't work. As I am typing this, the phone (currently at a much higher charge) is successfully charging from exactly the same machine and same USB cable that it wouldn't work with last night while at 6%... what gives?
Has anyone else experienced this?
For the record I am running CyanogenMod nightlies (2013-06-10), however I am finding it difficult to believe that software would have an impact on this.

That's strange. I'm currently using my. Old x10 charger and got no trouble. The manufacturer should not have any impact for charging. You can use an iDevice charger if you really need juice. ( of course with the right cable )

I believe it's CM that not allows off charging... If I want to charge my old x10, I had to tun it on. If I connect the charger the green light tun on. So it go into flashmod.

I don't know how deep dose CM control the charging. Seems to be enough to make troubles... An answer from a dev would be welcome.
Hope I could help a bit.

Well like I said, at the moment (at 80%) it is charging fine using all manner of chargers (Apple iPhone charger included). It is only when I really need it that it doesn't seem to want to charge from "lesser" chargers

I guess I will have to restore Sony software on it and try at some point. It certainly doesn't seem like there is a good reason for this behaviour to be hardware related, I mean what if I didn't have the dock? (Again, need to test if the original charger will charge via USB in low battery state)

Not as bad as you seem to think
Ok, I think I've nailed this down. My Xperia Z dropped to 18% at some point during the weekend. And all I had to charge it with was an iPhone charger (providing up to 1.1A so that's still not too bad) and a USB cable without a data pair. This didn't start charging. However, luckily my friend had an LG charger with a USB cable containing data pairs. This did start charging! (And his phone charged using my iPhone charger with data-less USB cable) Unfortunately I am an idiot and didn't think to try his cable with the iPhone charger, but at least this is a start! (I'm starting to believe it is the iPhone chargers somehow, which is strange because electricity is electricity, and chargers don't discriminate)
I use my old N900 charger
Sorry to hear you have problems with the charger, I use my N900 charger to charge anything (that charges by micro USB - Including my Xperia Z) around the house with no problems. I can't charge the phone in a MAC or PC USB port if the device is not detected (even if the port has power), but I found out that lots of devices behave like this (I guess its a good way of forcing users to buy a "quick" charger).

Ok. It's effectively a start of and answer. It make me believe that the phone communicate somehow someway with the charger. But that sounds unrealistic.
You wake up my curiosity. Will try to look at this. But it will take some time.

That's odd, a micro USB cable doesn't change by the manufacturer, except if they change de voltage, i use the Sony cable and a GS3 usb cable at work, no any problem.
Anyway just in case i always prefer to use the manufacturer cable to avoid damage my phone.

We don't think it is the cable (unless it is a cable which only has the power pair and no data pair, that could be a problem), but rather the charger, that is causing problems.

Okay, I'm stumped. I'm already getting a replacement device from HTC under warranty so my problem is solved, but like many of you, I HATE NOT HAVING AN EXPLANATION FOR THINGS!
I'm also wondering if anyone else has had this problem? About 10-Days ago my Kaiser (Tilt) stopped charging via the automotive charger. The A-C charger works fine, but the vehicle charger sent to me with my device from AT&T completely stopped charging my device. I went to the AT&T store & bought a new charger, It didn't work. I changed power points, & cigarette lighter in the vehicle &, it wouldn't work. I tried the charger in the vehicle of two different AT&T sales guys & also tried multiple chargers, & it wouldn't work. Is there any reason why the unit would lose it's ability to charge via a vehicle charger while still retaining it's ability to charge through USB to computer & through the A/C home charger? It seems to me that if the charge portion of the MB was fried, then all charging would be affected.
So how can my device charge fine through all means EXCEPT the vehicle charger?
Again, AT&T is sending me a new device, but I hate not having an explanation for the problem, drives me Nucking Futs!!!
Any ideas, anyone?
Thx!
I dont want to sound rude but have you checked your power settings?
Under the "Advanced" it has a option for "When device is turned on, do not charge the battery when connected to the PC."
If this is ticked it will not charge via the in car charger.
It's a known issue, not just with the Tilt
I had the same problem with my Axim X50 and X51v.
The original sync/charge cable wouldn't charge from the car's lighter, while non-branded cables did so without any problems at all.
This happened with other Axims as well, so I know that it wasn't a defective unit.
I then purchased an HP Ipaq HW6910, and encountered the same issue with my wife's Mazda 5 - the HW6910 woudn't charge if the cable was connected to the charger, when I started the car. It only worked if the adapter and cable were disconnected while staring the car. This did not happen with my Mazda 3 or my Mitsubishi.
And another thing I discovered, is that some cables are not designed for use with car chargers, but they work perfectly with AC chargers.
I bought a couple of retracting sync/charge cables for my HW6910, they worked only when connected to the mains. But regular cables worked perfectly with both power sources.

OF COURSE I DID.
Yeah, It charges fine from the PC, & from an A/C source. But the HTC TYTNII car charger that came with my device, as well as replacement car chargers don't work.

Funny, I just ran out to the truck & grabbed one of the guys Blackberry chargers & it looked like it was working. But SK Tools reports an even bigger (negative) amp draw (like discharging twice the normal rate). So with the BB charger it dischages even faster. Maybe reversed polarity Guess I should've checked first. That's a moot point now though as I await my new unit. Weird though.
Well i was using a BB charger that worked fine up until this morning. i bought my phone when it first came out so it wasnt easy to find a charger made for it at the time. i never had a problem until today. i also noticed that the Usb terminal on my device was bent. i called htc but they charge way too much to fix it. i have no idea how or when the terminal broke but it does still charge when pluged into pc or into the wall. ill have to spend $80 to have ppctechs fix it.
wassup, i`m in SF Cali, I had a att 8525 that was doing the same thing. I assumed it was the phone when it 1st started happening. After a week or so it was bothering me so i started playing with it trying to figure out if it was a setting, bad flash, or hardware. I noticed that if the phone was off it wood charge but not if it was on. I started flashing my phone and testing (for trouble shooting purposes) and for the first 2 or 3 roms problem still existed, then one of the roms i flashed to would turn on the back light as if it was charging but no LED or charge, when this started happening I realized that if i turned my fone off it wood start charging and continue to charge when i booted the fone back up. So if when i got in the car i pluged in/ shutdown/ waited like 45 sec or 1 min. / then booted it would temp. fix the problem for as long as my fone was on the cable. At some point after that many weeks/roms later i noticed it was working correctly again, So I had decided it was a glitch in the rom, But i`m not a Dev. or fone guru so I really dont know what it was, but hope this helps someone.... PEACE!! ~bboyphrog1~beatz`n pieces krooh~

The slight diagonal slant on the bottom right? It's supposed to be like that. All AT&T Tilts (and I'd assume TyTN II's, but I've never had one to compare) have a mini-usb port that looks that way.
i looked at a 8525 and the usb terminal was straight. i even took a pencil and straightened mine out. it should be bent. that wouldn't make sense because the charges slot is not bent. i think the problem is that one side of the terminal is not soldered to the board and can easily be broken. in another thread 3 people have the same issue. as far as the car charger goes ill do some testing but until today it was charging fine while the phone was on.
this issue is known ,it even happens with the htc tynt.... by simlpy rebooting while in the charger it starts working again ..at least with mine.
I've had the same problem. I went to the lcoal AT&T store and they said they never heard of it so I thought it was just me. It looks like many of you have the issue. I wish I knew what it was. It was really bad with my 8525,
i thought Faria developed a cab to fix this issue in the hermes forum? might be worth having a search for it and when i get home i will see if i have a copy on my pc.
any of you guys get anywhere with this? I have exactly the same problem. posted in a couple of other threads actually.
Not sure whether the usb port is damaged, but it's certainly is slightly "down" on the right hand side.
It charges perfectly on the mains and perfectly from usb, but not in the car.
I have used a normal car charger, spent Ā£50 on a Carcomm powered mount and tried one of the separate chargers that you plug the standard mini usb cable into. Nothing works. This is driving me crazy (if you'll excuse the pun!) a the primary reason I bought the Kaiser, was for GPS.
Thanks
well i also just found out 2 of my minisync cables dont work anymore. 1 of them still charges the phone but neither of them sync the phone anymore. it still syncs fine through a normal usb cable.
I am using a moto Razr car charger and it works fine so far.
Okay, confirmed on my replacement Tilt: The USB port is arrow straight. Someone earlier mentioned it being lower on the right side & indeed my DEAD DEVICE was as such. Looks like a bad job of connecting the port to the device.
NOTE!!!!!!
It's a good idea to take a look at your charger before you plug it in to make sure the charger USB connector is not bent or mi-sshappened.
i have the same problem i went through 4 att car chargers adn 5 phones. They are crap. Its not the phone its the charger if you play with it you will see that it comes and goes. The end tip on the charger is bad doesnt make a good connection. i have yet to find a good car charger.
Mine stopped charging using the car charger supplied and a brodit. A friend's kaiser charges OK with the same chargers.
No-one has mentioned it in this thread, but my phone, shows "charging" in the battery control panel and the LED lights up to confirm this. The percentage charge value decreases as though it isn't being charged!
As others have done I noticed that the corner of the plastic centre of the connector nearest the reset hole was slightly bent and I assume (though can't remember doing so) that I missed the reset hole with the stylus tip and pushed it in. Menu driven resets for me from now on!
HTC Europe didn't know anything about this fault, so seem to be happy to repair / replace it under warranty. It's with them at the moment, so I'll have to wait and see.

Please let me know the outcome. mine is getting worse by the day.
Now I'm confused.
Because the device charges over USB I just assumed it would draw <500mA (the max output of a USB port) but the specs say it draws up to one amp.
Having owned a high-drawing device before (Axim x50v) I know that trying to pull this out of a USB port can blow your motherboard. So are these safe to charge over USB??? How does the device know whether its being charged over USB or mains - are there different charging pins on the connector?
Well I'm at about 2% battery life, and it will not charge. I'm using my computer to charge it. Charging it from the wall hasnt worked for me for a while, not sure why.
Anyway I was wondering what it can be? I doubt my battery's dead or something is wrong with the phone... I'm sorry if this question's been answered, but I couldnt find an answer on google.
If USB charging works, but not charging with the AC adapter then the adapter is either bad, or plugged into a bad power outlet.
Nope it's neither of those because Ive tried two working AC ountlets and two warking cables. However, that's not my problem, my phone died and I can't charge it :-/
Ya so the phone died. It didn't look like it was going to charge on the USB, really weird. Anyone ever have there phone refusing to charge? While it was alive I tried to run activesync; that didn't work. So what should I do?
Btw, I've had the phone for a couple months now and I haven't had any big problems. I don't think it can be my phone failing, worst case just the battery. I've had something similar before but it fixed itself, doesn't look like thats happeneing now.
Battery
Maybe charging from the computer wasn't such a good idea. I recommend changing the battery and the charger and always be a nice boy and charge from the outlet ::- ).
I had the same thing happen to me - the connector at the bottom was broken. I had to do a return to factory. I looked (using a magnifying class) at the bottom of the phone and clearly see a crack in the connector.
It doesn't charge from the outlet.... I kinda just explained that lol

Hmm my connector does look a little bent. However it would of had to be like this before, and it was charging until I let my battery get to 5% :-/
I had a similar problem with my Kaiser a couple of weeks ago - it started to crawl and a soft reset took over 15 minutes to come back up to a working state, after which the battery wouldn't charge. It definitely wasn't the charger at fault as that still works on my TyTN. Phone was about 3 months old, so called Vodafone UK who seemed to think it was software related and so provided next day swap out. Old battery works in the new handset so never did get to find out if it was hardware or software that caused it to die.
Here's what probabally happened... you meant to stick you stylus in the reset hole and accidently put it in the usb hole... thus bending your charging port. I did it and when I plugged it into my car it would actually discharge the battery.. but when I plugged it into an outlet it just wouldn't charge.. if I were you I'd go see if it charges in a car
I appear to have a similar issue when charging from PC usb, and have identified that if I put pressure up or down on the charger it will charge the kaiser. But if plug in the charger without applying directional force it will not charge. Currently i have a small weight resting on the mini USB chargin input.
So obviously something up with the connector. But I haven't jammed anything up the usb port to my knowledge. Are these ports really that flimsy?
Tilt owners: If charge mechanism breaks, is ATT cool?
Oh no, now I can't charge or sync my Tilt.
My power is slowly running out.
What do I do? This is covered by manufacturers warranty in a year, is
ATT going to take my Tilt back and give me a new one?
I need my phone to be working and working well.
Thoughts?

Charging from the computer should be better than the wall, given that the USB ports on the computer have a 5.5v output, while wall chargers have 5v.
I got the 16GB Touchpad few days ago and since i got the one with an american charger i cant charge it yet (till i get the traveler kit).
My actual problem is that it doesn't charge through the USB port too. I left it for like 24-30 hours charging through the USB port (with the cable that came with the touchpad) and when i try to turn it on, it shows me an icon of an empty battery.
Is my usb cable problematic or it just that the touchpad cant charge through the usb port from a PC?
ps: every time i plug the usb it get a message telling "to reliably charge please use the charger and cable that came with this device"
I have the same issue with a 32 GB one. I received it brand new, factory sealed today and it is going back to HP. I called HP, the cable is fine, works with my HTC phone, it's the USB port on the Touchpad, it's loose and losses connection. HP is sending a box with prepaid shipping label and doing a warranty repair.
I really love the Touchpad and I am a bit disappointed with receiving a new device with a loose USB port. HP has great support and I can't wait until I get it back.

Unfortunately thats not an option for me (returning it to touchpad), since i bought it from Ebay (thats the only way possible for me to buy a touchpad from my country).

What sort of power source do you use, if not the charger.
I've tried to use a computer, but it does not look like it's charging, but data transfer work.
I tried with an iphone charger, that sort of work. It complains about not getting enough power (iphone charger is 5,0V while the hp charger is 5,2V)
Bottom line. Use the original charger, just buy an us adapter. It works great.
There is another thread here sonewere discussing chargers for non US owners.

Im trying to charge it through my PC using the original cable that was in the box (tried it in a USB 2.0 port) and im getting the 'try a reliable recharging source like the USB cable and the charger that came with your touchpad'.
I also tried charging it with a 5.0V 200mA phone charger but it didnt work either.
Shouldnt it charge even a bit with the cable? im trying to charge it for 2 days now

Yes, tried the wall charger, then pc, a different usb cable, all had the same result. When I plugged in I could feel the USB port loose in the Touchpad itself, it had a bit of play and if I played gently on it, it would begin to charge or connect to the pc. When i let go, it disconnected from my pc and then gave me the charging error message. I purchased mine from an e bay store and it has a warranty for 1 year.
I would be happy to help you with yours, if you want to ship it to the US, it has a warranty from the factory. Pm me if you'd like help. I am certain that shipping to and.from US could be costly but I am willing to help.

Mine will only will charge from official HP chargers. This is much like my old iPhone 3g before all the generic manufacturers caught up. I suspect that the voltage and amp requirements are tighter than the USB specification, so it will be a crap shoot if you use non HP chargers.
With that said, HP has 30% off all touchpad accessories right now. Combine it with the cupon SAVE15HP

Don't worry over that, I can get what you need and ship it to you.
Also, in speaking to HP, any USB charger in the US works, they're considered universal.
Sent from my HTC Sensation 4G using Tapatalk
you cant charge the touchpad using a computers usb ports. it doesnt draw enough power. the voltage of the charger doesnt really matter, it needs at least 2 amps or it wont charge the touchpad. cell phone chargers usually only draw 1 amp or less and usb ports only .5 amps.

That is absolutely not the case.
I have only charged mine once with the AC-USB thing and I have been using it since I got it the first day of the sale. I use mine all day long and only charge it occasionally via USB to PC connection. I use the original cable from HP and another one from my Samsung Mythic (work and home).
The message that you get when you plug it in is misleading but normal on a stock TP. However there is a patch in PreWare that changes it to just default to charge and not bug you. Anyone who intends to use this thing at all with WebOS needs to get PreWare installed. In fact, some time spent at precentral.net would benefit any new owners. You will learn A LOT more about these little jewels. I spent a few hours reading stickies and interesting threads and learned a great deal.
If it is really plugged in (and you will know because your PC will tell you) and you get no charge, you have a problem. It should charge on or off while plugged in - mine does.

Now to be completely honest - the first charge I made out of the box was with the AC adapter and I left it in overnight like I had been told.
But since then I have never used the AC plug and I have let it get down to about 20% or so but no lower.
It very well may be that from a DEAD state, it requires the extra amps to jump start it, but as long as you have that initial charge it is covered by the lower amperage of the direct USB-to-PC connection. I'm guessing it came with a fair charge and you burned through it without ever plugging it in to the USB.
Bear in mind that not ALL USB ports on a PC are powered the same either. Older USB 1.0 and 1.1 are crap for power. Front or top-mount ones also may not have as much juice as the ones in the back directly off the motherboard. Look at portable hard drives, some come with a double-header cable to use two low-powered ports. I know my top-mount ones will not power my 1TB 2.5-inch drive, but the ones in the back do.
However, I am really surprised you can't pick up a standard plug in USB adapter for your country for a few dollars (equivalent) for wall. Jeez they sell them at the dollar stores here now. I don't know if a car adapter would output enough to do it but that is another idea. If you can get one, you should be able to bring it back easily enough. The 2 amp adapter does charge a lot faster.

LOL, I am really in a rare mood as this question has bugged me a little. So I decided to find some straight poop. Here is the best description I have seen anywhere.
http://www.maxim-ic.com/app-notes/index.mvp/id/3241
If you don't want to read it, the gist (as I understand it) is:
At 5V, the USB ports in a PC have to be able to source (provide) at least 500 mA (.5 AMP). However, depending on how your motherboard is provisioned (MOSFETs and diodes) that is limited/controlled.
The spec though, does allow as much as 5A to be provided. In fact, 2A is not uncommon if the other ports are not loaded.
So you could try unplugging all your other USB stuff or try another computer's USB ports.

Im trying to charge it through my PC using the original cable that was in the box (tried it in a USB 2.0 port) and im getting the 'try a reliable recharging source like the USB cable and the charger that came with your touchpad'.
I also tried charging it with a 5.0V 200mA phone charger but it didnt work either.
Shouldnt it charge even a bit with the cable? im trying to charge it for 2 days now

Given that the HP charger has a 2A output, odds are that anything much below around 500mA isn't going to charge the device, or at least not at a rate that'll offset the drain while it's running.
The USB ports on laptops often won't supply enough current, particularly if there's other devices on the same bus. If you plug it into a powered USB hub then you should be in business as they should supply more like around 1A generally.
My Touchpad charges from my laptop USB port, however it is slow. I am getting about 8 - 10% charge per hour. The screen needs to be off though, otherwise there is no noticable charging happening.
Mine is not charging with USB laptop at all. Need to use wall charger
I have XRON VB2.8 on my two touchpads and both show battery charging symbol when they are connected to computer via USB and yes the they charge very slow.
FYI, can't remember if WebOS / Govnah tells you what the current amps being used is, but if you are on Android tools like Elixir 2 tell you how many amps you are either discharging (-) or charging (+). So depending on what you are using (wifi, bluetooth, # of widgets, running applications, screen brightness, overclocking, underclocking, etc.) YMMV on whether or not you can charge via usb connected to your computer.
So if you are discharging at a rate of -750 mA connecting to a usb port on your computer will still have you discharging at a rate of -250:
Code:
[COLOR="Red"]-750 mA[/COLOR] + 500 mA = [COLOR="Red"]-250 mA[/COLOR]
mine charges in the usb port, but only if I turn off the screen or turn off the touchpad completely. my ports only provide 500mA, and with the screen off, the touchpad draws about 50mA, so it can charge at about 450mA. With the screen on, it draws about 760mA, so even when it's plugged in the USB, it is discharging at a rate of about (760-500=260mA).
I bought a crappy battery pack from dx.com.
the battery works but makes a horrible noise when connecting the phone to the 2A port ... 1A no problem
also it was cheap, chinese, and labled "power bnak" instead of "bank"... total crap
and then I thought... I have a practically new perfectly good huge capacity 12 cell laptop battery that is just sitting on the shelf doing nothing since I don't carry around my laptop most of the time and its connected to ac power with battery disconnected all the time....
what if I could connect a Usb port directly to the battery?
It could be a really overkill emergency charger!
Anyone knows how this can be done?

When you charge from the wall socket it's also the wrong voltage... you convert it

Directly meant without a huge laptop attached to it
It's possible
Some laptops will keep power flowing to USB ports without being fully on- possibly in sleep mode. Recommend doing that if that's the case, although that's quite heavy to carry around just for charging your phone.
A multi meter can tell you what voltages are coming off the laptop battery and radio shack or a local electrical supply store can get you the parts to convert the voltage to the same as the battery on the "power bnak" then it should just be a matter of making sure you have solid connection and plug in - that big of a power source would be great for camping or power outages.
Went to a music festival over the weekend and used a portable charger to charge my phone, this is the last time I remember my phone fully charging. Once it died and I got back home, my phone would occasionally say USB connected and not charge until it said USB disconnected. Now it doesn't say that anymore but it charges ridiculously slow...
-Overnight charging I got 40%
-Left my phone for 3 hours and got 11%
-Use my phone while it's plugging into the charger and the battery still lowers rather than charging.
I've tried putting it in Ultra power saving mode and charging it while it's off but there is no big difference, I'm mad cause this cable is supposed to be charging it super fast.. Writing this post while my phone is plugged in I've already lost 2%
Nothing is wrong with my cord or the plug I am using, it's all the same stuff I have been using before. Could there be a problem with the port or something? Helppp
My phone is also in great condition always had a case, and just got it this past April
*also my phone is rooted so I don't think I can use the warranty

Are you sure? Cords die easily. Can you confirm how many amps the cord and the plug are allowing to be pulled? I've seen different phones pull different amps from different cords and plugs.
You can un-root and get back to a clean phone if you want to take it back.

How can I confirm the amps? And all I know is I've never had a problem with the chord before and I've even tried regular microusb cables that do the same thing

*#0228# this will show ur battery stats. Post that info. Also the is a option to reset your fuel gauge stats but I do believe you need to be fully charged for this.

If you have tried other cables and get the same result, you may have a problem. However I have seen cords got from .44a to over 1.2a from two different phones though.

check the power brick your using, if its the Samsung one that came with the phone it should be like 2 amps if I remember. id suggest using another power brick to test. also if you have a usb 3 super speed port on a pc or laptop sometimes you can use device manager in windows (start menu, right click computer, manage, in the window that opens click device manager, expand the universal serial bus controllers heading, check though any devices that say hub and go to their power tab) to see how many amps something is pulling from a pc usb. the other option is that you might have a defective battery but I don't know for sure. these are just some ideas that may or may not work for you.

Sounds like the portable charger might have been able to adjust amperage or voltage. If that's the case the portable charger could have damaged your battery if it was wrong amp and too high of amps. I have a portable charger that even changes voltage that could ruin a device too if not on 5 volts.

It sounds like it could be a battery problem. More likely, it could be a problem with the software. I would back everything up and flash another ROM or bring it back to full stock.
Option 1:
Install this app https://play.google.com/store/apps/details?id=ccc71.bmw
It will tell you batter voltage and charging current.
Options 2:
Charge with phone powered off.
Thank you everyone for the replies, my phones been getting worse to the point where it sometimes wont charge.
I think what im going to do is flash back to stock and bring it in to samsung or something , but also i heard a rumor that towelroot doesnt void the knox warranty? if this is true i may just bring it in as is...only becuase when i connect my phone my laptop wont read it anymore either, i havent tried if odin will but im assuming it would, i just dont want my phone to end up bricking because of the bad connection
This sounds like an old problem with Samsung phones, including the Galaxy S series. My original Galaxy S did this, my S3 did this, my sister's S3 did this. On those phones it was the charging port that caused the problem. My sister had her port replaced and her phone is working fine again.
Although I don't know for sure if that's your problem, that would be my first guess.

Yeah I'm pretty sure it has to do with the charging port, my battery is fine and so are my cables, and it randomly keeps saying USB connected/disconnected and won't change when it's "connected"
