I got problems with WP7 battery charging so I decided to find out some infos about it.
In WM to build external charger you need to cross D+ and D- in usb (signal wires). In WP7 it's doesn't do the trick, it wouldn't charge.
Also USBHub also doesn't charge it.
The only way to charge TG01 in WP7 is to plug it into computer's usb port, then red led will appear and it will charge pretty fast.
If your battery got drowned too low to boot the phone, recharge it manually witl cut usb cable and red wire to + and black wire to -, hold about a minute or two and then boot the phone and charge.
Is there a solution yet to charge the phone in WM7? Can not we make a home charger?
thanks
you can. I am charging phone with regular charger i got with toshiba

the same here- i have no problems with battery or charging .......
So toshiba charger does something else than just shorting d+ and d-, I've built my own charger which works in winmo, but doesn't work with wp7
ok, thanks for the explanation
Hi,
i also use not orginal charger and it works fine ,but problem occure when battery will got drowned.
In this case the same charger will cause that led will be orange suggesting that charging process was started ,but in fact it won't charge. (phone was left in this condition for 10hourse without any progression)
I had the same situation with wm6.5 and then it was enough to plug this phone to usb, after a while it was able to charge.
But when you have wp7 phone will try to continuously boot up and charging won't start. So one solution is as Aeroflyluby wrote: charge this battery manualy for a one minute or you can do as follow:
1. plug phone into usb
2. hold down volume - and volume + and press power - this procedure will start bootloader menu
3. press volume + to select boot source = USBFb serial
4. press volume - until you will see Device ready to download image...and orange led lights up
there will be of course error information but it doesn't matter.
Important is that this procedure will force charge mode .
This procedure will not damage or erase your current ROM.

I can confirm that need only short +D and -D. I convert a generic car USB charger for my toshiba with this method .

Hi to all knowledgeble folks
My wizard on 02.
Will not charge thru usb, the battery was at about 12%
when i connected it to the pc the orange charge light came on, i left it
be now I ve just come back to it and theres nothing i cant use the mains adapter coz its at work my usb is a mains powered hub
any ideas :roll:
Hi, the usb has not enough output to charge wizard when its dead. You need the mains charger i am afraid. Even then you have to leave it connected for quite a while before the light comes on. Some people have had success with a car charger if you have one.
If you've got a spare usb cable you can cut the plug off, put the + / - wires against the relevant points on the battery, and leave it for 15 minutes. Should give you enough charge to boot the OS, at which point the USB connection will charge it.
Worked for me.
Contacting the battery terminals for just 2-3 minutes will give it enough charge to start up and give you time to place the USB charger on it to continue and complete the charge.
This is a fix that really works. Much cheaper than getting a new wall charger.
Oh, and (usually) the red usb cable is positive, the black negative. But I take no liability if your battery (or the PC) goes pop!
wizard wont charge thru usb it does now
:lol: :lol: :lol: meschle Webreaper jschaff
Your all stars i did the trick with the cut usb cable works a treat
Many MAny thanks
I powered off the phone last night and left on charge. Unplugged and tried to power on this morning and nothing happened.
Ive gotten to work now and plugged it back in and even with power connected it will not start.
Additionally the power light occasionally blinks off and back on twice in succession.
*UPDATE* insanely the problem i Had with both usb and mains intermittently not charging (or al least showing the red charging light) has gone but the phone still wont boot.
I have followed some of the soft reset advice holding in the power button for two seconds and the reset for 10 and apart from the power light flashing nothing else is happening

I am not sure Your battery was charging at the night. You wrote "and left on charge" but did You notice tg01 started to charge ?
Such effects with blinking leds are typically met on some tg01's when battery has been discharged too much. There is a problem to charge it inside tg01 then.
My advice is to charge battery a little bit in external charger ( to about 3.4V if You have opportunity to measure it ) and then continue and finish inside tg01.

damn i havent got an external charger
Yes the light did come on to show it was charging but it was still on this morning some 6 hours later which it hasnt been normally but you are right in your assumption that it had drained completely, it hadnt when i started trying to plug in the charger but by the 50th attempt it had shut itself down completely.
i was umming and ahing about getting one on ebay the other day and opted for the micro to mini usb adapter in the end which ironically has arrived today.
is there one in partucular you would recommend?

Unfortunately I do not know what models are available on the market. I even do not know whether such devices are available at all for tg01 battery.
I am electronical engeneer so for such purposes like Your ( one time usage ) I utilize anything I have at home . Colegues from the forum, having the same problem, utilized DC power supply with voltage and current limitations and it is cheapest solutions if You of course have such device. I do not know what are Your manual and electronic skills but as I mentioned You do not have to charge externally the battery too long ( to about 3.4V ) so other solution is possible but it requires any multimeter , any non regulated DC power supply and resistor to limit charging current. As DC source You can utlize USB socket . As You see You have some options.

here i find the link for you - http://forum.xda-developers.com/showpost.php?p=9587737&postcount=19 for external charge for ur tg01
Awesome - thanks - have seen similar mains powered items on ebay. will grab one of there for £4 delivered.
YAY
Universal charger arrived lunchtime, went home, brought it back to work and now have a 70% charged battery and working TG01
BOOH
Despite the fact that when the battery was dead every time the usb or mains charger was plugged in the red charging light came on, now the phone is ON the usb connection is again not working

using a mains charger works but its back to not connecting every time, i thought it was the usb port but now i really don't know. am starting to lose love for this device rapidly at the moment

Once again.
Mains charger works every time but You are not able to establish connection ( active sync or mass storage mode ) to PC ? ( not every time ).
If yes, maybe micro USB plug from cable You connect tg01 from PC is damaged or cable itself has any internal damage causing that one time connection is possible, other time is not possible.
Worse possible scenario is that micro USB socket in tg01 is damaged ( transmission lines or ID line ).

1. My phone never charges when the phone is completely off. It seems to only charge when in Android. Is this normal?
2. How do you enter that rapid battery recharge service mode from the boot menu's? The mode I'm referring to is when the phone has not booted Android but all it's doing is recharging the battery with the screen off. If you press the power button, the screen turns on for a second showing you the battery level.

Mine does that by default. When I plug it in to charge when three phone ifs switched off, it well show me A image of a battery with water like thing inside our and the charge level..
Did you change something in the phone?
Sent from my Motorola Razr using XDA App
I decided to try a USB wall charger and it's now showing that image of a battery.
Do you ever see that battery image when you plug the phone into a PC USB Port? My PC has decent powered ports (almost 1000ma) but it just won't charge the phone when powered off. But charges when in Android.
I basically only flashed a retail ROM and updated the Radio.
Something to check into is the USB cable that you are using...swap it out with another one.
Speaking from experience with a different Android (DInc), I know I have plugged it into some cables that provide just power via USB (no data) and then I am guessing there is the possibility that there are some that provide data and no power.
The USB cable is perfectly fine, I tried another cable anyway and the same thing happened.
I tried three PC's including a Desktop with decent USB ports, none of them charge the phone while turned off. I tried two USB Wall Adapters and both can power the phone while off.
So it seems that if the USB Port cannot supply more than say 1.5Amp or 2Amps (basically all PC USB Ports), it won't go into battery charge mode.
So I pay £45 a month for my Samsung galaxy mega 6.3 I've had it for a month and a half now and its a lovely phone, works well and everything, however all of a sudden I plug my charger in and it constantly flicks between charging and not charging (the little lightning bolt symbol appears and disappears constantly) whilst the cable is firmly plugged into the phone, this is when the screen started to flash at me and click on things I haven't touched , the most common thing it does is switch on driver mode , the back and options button flash at me and the screen switches on and off rapidly, I've reset the phone and tried a different battery and still the same result, its not as bad now, when I put the charger in this time the screen doesn't go weird it's fine its just my phone will charge but after 5-10 minutes it will stop charging again and I have to go and unplug it and plug it in again, this is seriously annoying so is it a malfunction with the phone? Is It something I've done? Is there an easy way to fix it? I need help please!
Is that the same when you charge your Mega through USB cable from PC? If yes, then it is phone's hardware problem, but if NOT, I would suggest to change charger.
Charging from PC is also possible, but the charging current is about 1/4 th of current from dedicated wall socket charger - the phone is charged although much less intensively.
Nominal charging current from wall socket charger is approx. 1.9 amp so if you need to find new one, choose wisely and accept only charger with 5V 2A specs.
Hello, my Huawei y300 (u8833) only turn on and works while I plug in my usb cable either (charge). My phone doesn't turn on when i press the power button and I'm on just my battery, amazingly it turns on instantly after i plug in the usb charger and remove the battery. So i got a little tired of having to plug in my phone all the time and not use it on battery. Any help? I dropped my phone 9 months ago and it didn't work back then but i never tried the usb cable on without battery. But now after 9 months i plugged in usb cable and no battery and *boom* it works. Any advice as to what is going on? Can i ever get it to work from my battery? (BTW there is a red notification light (not blinking) if i put battery in along with usb cable. Thanks for any help.
Update: Somehow its charging my battery!
Update: (PS:I'm rooted and have cwm)
Update: I'm fuc*ing stupid, its now working on battery! Sorry to have waster your time
