touch HD battery questions

the first battery charge on the HD is supposed to be a 8 or 10 or 12 hour charge? or on its not necesary
also the time used to charge it to the pc via usb cable is same as if ud plug it in the electric socket?
how long dose it take for u to charge ur phone.....
mine had 4 lines out of 10 and after 3 hours of it beeing conected to my pc and not in use its still got 4 lines....

opinions seem to vary on how long for 1st charge - personally I left mine on (mains) overnight, but that's just because I've had mobiles since year dot, and you used to have to!
But charging via PC doesn't seem to work as well as from the mains charger - depends a lot on the PC and how much juice it kicks out, some are a lot better than others.

Modern phones/batteries do not need "overnight" charging. My Touch HD even came with a little note saying you don't need to charge for 16hrs/overnight. Just charge until it's full...
Better to charge with wall socket because not all USB ports provide enough current. Some can't charge through the USB port while some can.
I can charge through my notebook but it takes a lot longer than the wall socket.

thanks bouth of u for the fast anwsers....

When I set WiFi settings to max performance, my HTC HD will not charge at all, actually it will loose charge during night, display is off, just WiFi, GSM and GPS is active, connected to provided wall charger. Back side of phone is really hot, I measured over 54°C

Problems charging.
guys(and lady's) Just got my HD. been running it for some time to drain the battery, while on my laptop the battery starts charging. I wanted to drain the battery to give it a good charge afterwords so I turnd off the option of charging while unit is active( in batt. menu) but When I got to 5% batt.cap. an tried to charge the unit (batt. option enabled again) it doesn't charge. now my batt. is empty and can't get in the phone. while on power my battery charging led gives a couple of seconds of charge indication then it turns off.
Any suggestions or is my battery dead. (charging unit is oke, and when on power the HD does give sufficient power to the battery (measured with mulitmeter) thx guys edit - Als when on power green and amber lights blink.

Could that be that your battery is too hot ? There is some safety protection that prevent the batyery to charge when it is over a temperature level.

battery not charging properly
My touch hd not charge the battery more then 50% i change the battery but same as before.
any suggestion
Regards

Touch HD Battery Charging Problem
The rom i am using is Energy 3 Rom
and try to use both sources wall socket and pc usb both are same.
if i charge the battery on usb cradle and put the phone it shoes 100% but after some use of the phone the charging start again and never show's full even left it over night.
Best regards

Not sure what's going on there,but try draining the battery to almost empty each time and then turn your phone off before charging it. Do this a few times and see if it helps. Mine took about a month beforeit came good.

Dear samlives
Thanks for helping
I will try it
Best Regards

HTC Touch Battery Charging Problem
I got a solution its not 100% but for time being its working for me.
Long press the power button and put the device in sleep mode.
All Done now charging 80 to 90% quite better then before.
Thanks a lot

Battery drained out totally while connected to PC

This morning I almost got a shock because my X1 stayed black and seemed to be totally dead. Luckily I soon figured out that the Battery was empty, no currrent left on it to let the device even blink. But what happened? When I went to bed yesterday I connected it to the USB cable and left it charging! Everything seemed the same as all the times before. What may have caused this?
Only things that were diffrent from my usual charging procedure:
The Cable were connected to the PC USB Slot.
I shut the PC (laptop in this case) down but the USB Slots had still power. The charging lights of my X1 followed their normal pattern.
Normally I unplug the power cable from PC to prevent the USB Slots to have power. Because my USB harddisk keeps rotating while having power from the USB.
Normally I charge the X1 directly from the power outlet. X1 turned off.
So this time PC was off. X1 was off. USB Slots still got power. X1 connected with USB Slot. X1 seemed to charge normally.
Well, the result was that my X1's Battery was totally empty the next morning. Obviously instead of charging the USB slot drained of the whole battery power! But note that the charging lights were active as normal and the Battery was still warm in the morning.
Perhaps this helps others to prevent such issues.

you are crazy if you:
1. charges from laptop
2. from powered OFF device
you can repeat this case endless - xperia will be drained

Don't charge it in standby mode, how stupid is that?

What? I don't see any reason not to charge it from a laptop. Even if it's powered off, as long as the USB ports have power (mine has a BIOS setting for this) there is nothing wrong with that.
Also, what does it matter if you're charging the phone powered off or powered on?
On an interesting note, however, the same thing actually happened to me last night.
I plugged the phone into the wall socket to charge it (battery was at about 20%) and I actually saw the battery percentage rise as I was still using the phone. I turned it on in the morning (from standby, not powered off), and as soon as I pulled the power cable it went dead as the battery was completely empty.
I have no idea what might have caused this, and it hasn't happened to me before.

Next time dont power off ur X1,
if same happends then your battery is suffed.

1) This was accidently
2) Why? I dont like it when mobile phones are on standby while I'm asleep. Charging the device when powerd off should make absolute no difference? Worked everytime but the one where it was connected to a powered of laptop.
Why will the Xperia been drained?

Do you mean standby or powered off? Why should it make any difference? And why does the battery getting drained?

What does this BIOS setting say? I assume that my USB slots had too less power when laptop is off. But its very strange that your Device got drained while connected to the wall socket and in Standby mode. Maybe my USB slots were not the cause? Weird ...

It is weird. Since your phone was off I don't think it would use any of its battery power.
I have a ThinkPad, and IIRC the BIOS setting is something like "Always On USB", in the USB settings. With this turned on the laptop will power its USB ports even when turned off, as long as the laptop itself has the power cable connected.

from powered off PC, when power on usb enough to wakeup PC or feed LEDs,
but not to charge another device. in that case power go into the weaker side, means from x1 -> pc

I had this problem too... seems after hard resetting my phone one time, one option was different to normal after I hard reset,
Click on the battery icon at the top of the screen
Theres a tick box, that says:
"When device is turned on, do not charge the battery when connected to the PC."
this was ticked for some reason. Unticked it, and all was fine.
Try it

I noticed this happened to me too for the first time, after i put in the wall charger and the the phone seemed to charge, i found it completely dead after 3 hours and the battery was warm, running a vanilla R1A

Also I think for the X1 to charge- it requires activesync. from my experience, when connected to the pc- without activesync, the X1 would indicate charging- but never actually gets charges. Hence when your notebook is off, activesync obviously wouldn't be running-> no charge either.

I assume a turned off PC would only power its USB port power pins and wouldn't respond to any transmissions on the data pins. So to the phone it should look just the same as if it were connected to the wall charger (just probably with a bit less power).
Also, when I have my phone connected to my laptop through USB Internet Sharing it does actually charge (it doesn't connect to ActiveSync when using Internet Sharing).
The device should charge in any USB mode as the USB port's power pins supply power regardless of the protocol used on the data interface.

Does the X1 have no safety feature that does prevent the battery from being drained?
In my case I assumed it happened because of the USB Port had too less power. But when you turn off your PC (+USB power) and let the X1 connected it would still mean a movement of current from the X1 Battery --> inside the PC as long as they are not on the same potential. If the PC is earthed somewhere (for example connected to the wall socket) the Battery would be drained out totally! They never get to the same potential as long the Battery has power.
As jjm34 mentioned, if the PC is on and USB slots powered normally the X1 should charge in any case.
Maybe this is not the real cause of the problem. People are reporting that the X1 got drained while connected to the wall charger! That's really weird. How can the battery being drained by this? Any suggestions @Ethermind ?

It could be:
It's drawing power FROM your x1 to provide power for laptop internal components.

Mine has. Put it on the wall charger and the charging symbol is there. It reaches 100%, the charging symbol disappears and it shows 100. Then in the morning it's at 90% even though it was still on the wall charger.
I've not left it plugged into a 'running' pc or laptop long enough to see if the phone runs off the battery after it's reached 100%, but it shows the same symptoms. Charging symbol until 100%, then it changes to 100%, no more charging symbol.
Even MSVC stops reporting '% & charging', just reports the % level once it's reached 100%.

I made 2 observations :
It seems the X1 need usb data pins active to charge the battery. The wall plug has something enabled to give power to the data pins (by the way, the wall plug can charge an iPod or an iPhone, it works perfectly). I tried using a cheap wall plug bought in china, no way to charge the X1 or my iPod as there was no power on the data pins. So when connected to an off PC, I'm not sure what's happening. If someone can give a try to analyze this with a multimeter, that would be nice.
It seems also the X1 stop charging after going to 100 %, and won't charge anymore unless you unplug - replug it.

Thanks for your contribution.
Maybe there exists a real hardware failure.
Normally the X1 should charge until the Battery reaches the 100% level. Then there has to be a switch that prevents the Battery from getting overloaded which is good. So charging stops.
The switch blocks charging until you unplug the device once it has reached the full battery level. Thats ok, too. You should not loose much Battery after a full charge and with a device on standby or powered off. And it prevents the Battery getting reloaded at high percentages. Otherwise it would start charging at 99% and stop again at 100 and so on, all the time.
But now assume the switch has sometimes, somehow a failure.
Instead of preventing current to get inside the battery it enables that current can flow into the wall charger.
I do not expect that the current flows into the power outlet. Maybe it gets "lost" in the current transformer that you've plugged into the power outlet (Thats the one you plugged the USB cable in.). Lost means it simply gets warm / hot.
Measuring the current with a Multimeter would be a nice proof. If someone has the technical knowledge and qualification to disassemble the current transformer and the USB cable, you have the go .

I haven't tested it, but I doubt the current flows back into the charger, or back into the USB port on a laptop / pc.

But how does the Battery discharge then? When there is no current flowing out it will stay loaded. (it goes like d(q)/dt+div(j)=0 )

Did you all charge your phone while it is on (standby)? I noticed the same problem when I charged my x1 while it is standby. When I pull the plug from my laptop (I used my laptop for charging, laptop powered on), I get 90% battery life. It seems like there is a switch to cut out the power input if the battery reaches 100% and power the phone from the battery.
Try to charge your phone while it is off. I did it yesterday, and it had stopped charging even before I unplug it from wall output, and I got 100% battery life.
Btw, this is not confirmed yet... it is just based on my experience...

Battery charging in "old school mode"

I forgot the usb cable in the office and I have to charge the HD2 battery. I tried connecting the PSP charger directly to the battery blades for 30 minutes but nothing seems to have charged.
PSP Charger: 5Volt 1500A
The HD2 battery have 3 blades:
[+] [?] [-]
Did I have to use the blade in the middle as positive or negative?
Do you know anything?
Thanks

The middle one isn't needed for bare wire charging.
Just a thought but did you put + to + and - to - ? ( which you should)
Got an old mini USB cable? Use that, end off, black to - red to +,,,, and thirty minutes is about 28 minutes into the danger of explosion/damaged battery zone.

Try to measure charging current with a simple multimeter if got one and put a 1.5 kOhm resistor in series with battery and charger. This should limit charging voltage on battery poles to regular 4..4.2V as needed for Li-ION battery charging. Seems like internal battery security circuitry detects overvoltage (above 4.3V) and cuts off charging.

Phone doesnt reliably charge when connected to PC

Anyone else notice the phone randomly doesnt charge when plugging it into the computer?
The battery will say charging, the lock screen will say charging, but the battery screen will say not charging and the graph will show a green charging line but draining battery. Replugging the phone in fixes it. I havent had an issue with the wall charger.
Theres nothing wrong with the USB ports, it charged my other phone fine and it charges this phone when it works.

my N4 charges fast when I plug it to my laptop. I connect it to my USB 3.0 port..

PCs aren't designed to charge phones. It may work for a dumbphone with a 500 mAh battery, but it doesn't have the amperage to charge a smartphone efficiently. The charging adapter that comes with the phone is 1200 mA (milliamps), a computer USB port only provides 500 mA (on USB 2.0). On USB 3.0, it provides 900 mA, so it will charge faster, but not nearly as fast still as the 1.2 amp travel adapter.
On top of this, the phone is constantly using battery power while on, so it is very likely that when the screen is on and you are using the phone plugged into the computer, the phone is drawing power faster than the computer is charging it.

That is not what Im talking about. It says charging everywhere except the battery screen where it says not charging, that is obviously a bug. A computer can power a phone fine anyways, they are made to be powered by a USB port.

I had this problem today. The battery was dying fast (Average for this one) and I had popped it into my stereos USB, The battery didn't show the charging sign.
WTF? So I switched to the "Cigarette lighter port" and with a different cable plugged that in. No go. Held in the power button to simulate a battery pull, Still didnt work.
Turned it off, Went back to work and three hours later getting ready to drive home i plugged it in. The phone was getting warm, But the battery charging sign never popped up. I turned it on and the left side (By the sim card) was getting ultra-hot but betterbatterystats said the battery was only feeling at around 101degrees (Normal for this small sun). A minute later it was highly uncomfortable to hold (Just near the sim card area), I thought the battery was going to catch on fire like those youtube videos.
I power cycled once again, the battery charging sign popped up and I breathed a huge sigh of relief. Seconds later the phone ****ing flipped its wig, It kept making the charger plugged in sound and vibrate every half second. I about had a stroke, Thinking it's going critical. ONE MORE POWER CYCLE, Everything is normal.
My earlier experience seemed similar to yours OP, Let me know if your phone melts your hand off and goes all bi-polar like mine did.

I'm having the same problem. It has nothing to do with a computer not being powerful enough to charge it, especially when they aren't even being used such as overnight. It has charged every other smartphone that I've used. It will say that it is charging on the lockscreen and on the settings pulldown but it will just constantly drain battery. I will put it on the charger before bed and wake up 8 hours later and it says it is at 86% with a steady decline in battery. This only happens when connected to my iMac and not when plugged into a wall outlet.

I wouldn't think USB 3.0 improves the charging speed at all, since the protocol still uses USB 2.0

I just remove all the cables and replace them. It seems to solve it.
Same with the AC adapter. I noticed sometime it would say charging USB when I switched. I just unplug everything and plug it back in and it goes back to normal.
/shrug

I havent noticed it getting warm, it just doesnt charge even though it knows its plugged in and is supposed to be charging. It works after replugging it in.
It also seems to charge abnormally slowly.
I wonder if the issue with the phone not working right with Nokia chargers (constantly disconnects and reconnects) is related to this. It may not have anything to do with the Qi standard because the phone just doesnt charge right period.

Photon Q got hot now won't power on

Hi everyone,
My Photon Q was probably about 30% charge when I last checked with it on. An hour or 2 later it was a little warm and was off. So I went to charge it using the car charger with 500mah charge rate. I came back about an hour later and the phone was really hot and no charging screen so I unplugged it. The green led light is lit when the phone is plugged in.
I tried holding the power button and volume down button, but it won't boot. If I have the usb charging cable plugged in from a PC or charger adapter when pressing those buttons, the green light will flicker off for a fraction of a second.
I then proceeded to dismantling the phone as I suspect a battery issue and the one in this phone is stupidly non-removable. After taking the back cover off, I tested the battery posts and received 0 volts. I still don't know if the battery caused the drain or if there's a short in the phone. I then took off the inside cover that holds the battery in. A few T5 screws later and the battery was removed. I connected the battery to some AA batteries in series to see if I could get a charge. A few hours later I got it up to 3 volts which held for several hours. So I connected it to a few more AA batteries in series to try and raise the voltage. I got it up to 3.67 volts and the battery is listed at 3.7 volts.
A day later and the voltage is still at 3.67 volts so I put the battery in the phone. I went to try and power it on, but nothing. I then connected it to a usb cord and received the slow flashing red led light a couple times before switching to green. The battery started getting warm again connected to the usb charger. After 20 minutes it was approaching hot so I unplugged the USB. The battery read 3.54 volts. 30 minutes later, 0 volts again.
Does anyone know what the actual voltage range is for this phone, as my old Samsung M320 is also 3.7 volts, but when testing the battery I get 4.10 volts? I heard it's pretty specific on minimum voltage. Any ideas for a temporary battery or way to boot the phone before spending $50 on a replacement battery and then find out there's a short in the phone. Is there another key combination to boot the phone, I'm trying to boot it to at least get my pictures and other data off it.
Thanks a lot in advance
Matt

Not the battery, seems to be an electrical short but where
I bought a new battery for the phone which had a 0 volt charge when I received it. I tried putting it in the phone as is to use the phone charger to charge it, but got nothing. So I charged it using 2, then 3 and then 4 AA batteries in series to get it up to 3.7 volts. I then put the battery in the phone and noticed the 2 large chips and the chip centered above them located by the camera get a little hot. I tried with the charger connected and not connected, but same thing. Power button doesn't turn the phone on. Just the green led lit when the USB power cable is attached. So now it seems there must be a short in the phone. Anyone know where I can look to check for a short, blown resistor or something in this phone? Or at least where the rom chip is located so maybe I can turn it into a usb drive to get my data at the least.
And sorry about the double post. I didn't receive any replies in the other section and I really need to get some data off the phone. Seemed the hardware section would be the place to check. Tree fell on the house and pictures before the tree was removed were taken with the phone which of course ironically stopped working right after.
