Hi,
I am unable to get my Galaxy S2 charged with an External Battery for Portable Devices (e.g. Just Mobile Gum Pro 4400mAh).
With the Galaxy Ace I had the same problem. After disconnecting the USB data wires, keeping the power ones intact, it worked fine, but that does not work with the S2. Anybody else having that issue? The USB cable charges with wall charger and PC.
I would hate to buy a new external battery. :-/
Thanks,
kuschel
Could you rephrase your sentences. I am not able to understand the problem clearly.
Sure. The phone does not charge when connected to the battery pack. Charges fine with the same cable using my HTC charger.

Which battery pack is this? Do you have any link to it? What mode is the phone when its connected. Is USB debugging enabled?
Same battery pack here, and same problem... Deactivate usb debug and it will charge. Too late for me... Already ordered another battery pack... Oh well...

I'm using a Pebble and it works perfectly
Charging works after reboot
I found a partial solution. I connect the battery pack to the phone as if I would charge it. The GS2 does not show any sign of charging. Then I turn the phone of, it automatically boots up again & shows that the battery is charging - guess that works for me.
PS: After a disconnect I have to do ist all over again.

This works for me also. Enabling or disabling USB Debug doesn't make a difference with the Gum Pro.
interesting i have an energizer xp8000 and about to try it on my S2 hopefully it works but thanks to this thread have some work arounds to try too :
Glad I am not the only one
Thanks for the info. Until someone finds a better solution I am glad to know it's not me or my phone.
well i can confirm my Energizer XP8000 battery works with S2 fine = 52hrs http://forum.xda-developers.com/showthread.php?t=1115104
XP18000 and ZaggSparq here charges my SGSII fine. It charges both in regular mode and USB debug mode.
just wait a while for extended batteries then you wont need an external battery. i have posted two links in the thread have a look in the thread forum.
I've used Proporta's 3400mAh Turbocharger battery without problems. Haven't tested it fully to see how much it recharges the phone, but I've gotten at least 50% charge back from it.

advantages of a good external battery is being able to charge more than one device i.e. notebook etc
I have the exact same issue when using a mini USB charger with a Motorola Mini to Micro USB converter. When I connect my charger, a pop-up on the notification bar shows "USB host cable connected", and it won't charge until I power off the phone. When I plug the charger while the phone is powered off, instead of showing the charging animation, it will boot up instead and start charging. Charging using the stock charger or PC work just fine. And I thought I was the one that created this complication while flashing different ROMs and kernels, but it seems like an issue with s2 phones.

I found that a lot of cell/mobile phones will not charge useless the two data lines on the usb adaptor are connected together , I have modified a number of usb adaptors myself to get them to work, some phones need certain resistances on the data lines before they will charge.
I use to have a Samsung galaxy tab 7" and it was super fussy about the chargers it would work with, I found this thread and this guy had found an usb to usb adaptor that has all the need fixes so you can easy make any usb charger work.
All my usb adaptors seem to work with my SGS2 without any adaptor so i dont know if this would work for you.
EDIT : unless you know what you are doing, dont do it.

I bought this and guess what:
http://www.amazon.co.uk/TeckNet-Dua...dible-Blackberry/dp/B000NDQ92W/ref=pd_cp_ce_1
the phone is discharging rather than charging while the battery icon shows that it charges.
more specific: I connect the phone to USB 1A port, I hear the beep tone and I see the battery icon turns to thunder icon , just the normal situation which shows that the phone is in charging mode. OK?
IF I use the phone (i.e. browsing with WiFi) the phone's battery level is dropping down instead of getting up. I use a battery app and I can check realtime the percentage. I must have the phone in standby on order to get charged!
Unbelievable but true! The external battery cannot hold the consumption while in use, even when connected to 1A port!!!
solution - how to charge SG2 with Gum Pro
Hello kuschel,
For me the following solution helped:
Just plug in your cable to the battery, switch it on. Then plug your cable into the phone but veeeeryy slow until the "MTP application" pops up. After that you can move the plug to its final position normally - your phone is loading.
For me it looks like to be a software issue - since I updated my phone to the current KIES version and rooted it (German KF3 Samsung original) I've had that issue no more...
Cheers

Well look at that. Worked first time and now my mobile gum battery pack is charging the phone just fine.
Which is a real shame as I have now ordered a replacement battery pack and the gum pro was actually really small and compact for a 4400mah device.
Hi, anyone know of a decent car charger that will provide enough power to charge the phone when it is being used with GPS and screen on? Currently when im using navigation the battery goes down even when its plugged in!
Thanks
[SOLVED] I just picked up the HD multimedia dock for my Atrix and have been using it in the evenings with my phone and love it! I have noticed that strangely it drains my battery! Much faster if streaming Hulu or something though. Yes, the power supply is attached
Have you experienced this? When I sleep the phone, it will charge it to 100%. Wondering if I have a dud. Wanted to find out if this is "normal" before I try to reach Motorola for warranty.
UPDATE - I failed to mention that I was using one of those wonderful Chinese cells I got on Ebay in the phone. Once I placed my OEM battery into the phone, the discharge appears to have gone away. Updated this post just in case someone searches for this in the future.
TJD
did you plug the dock into the wall? It suppose to charge your phone also, not drain it. Double check if you got an A/C adapter with it
Indeed as my question stated, it is plugged into the adaptor and it will charge to 100% once I turn off the screen.
By the lack of folks chiming in, I assume I got a faulty wall wart, so will start the process of figuring out how to exchange the power supply under warranty.
the dock can be kinda funky sometimes when it is plugged in. watch your battery icon to make sure it is charging when it goes into the dock. There are some comments about this on the motorola site. Sometimes I have to unplug the adapter and plug it back in until a couple of times before the charger "kicks in". the mods on that forum suggest plugging directly into the outlet, not a power strip.
On my primary car I use a USB adapter to charge the phone. Prior to the SG2 I had a HD2 which (I think) charged fine.
If the phone has a zero charge I plug it in and it will automatically boot and the charge indicator shows charging but the battery indicator does not move for a while. Charging when using the phone never seems to keep up with the charge. After about 5 minutes the top indicator (when phone is on) starts to move and the phone will charge - although it seems pretty slowly.
The weirdness - when I plug in the USB cable to a laptop when its off the battery indicator lights up on the screen (pictagram) showing the phone is charging but it doesn't boot which is correct. What is weird is below:
In the car when you attempt to turn it off the phone with the long power button press and select the right options the phone will close down - you get the TMobile logo then the screen blanks out - then IT REBOOTS on its own!
Could under voltage be doing this? or is the cig port doing something odd with the voltage or amps? Know the USB port works and charges because I can charge it off a laptop, wall charger, computer etc and it works as it should. Its not the cable because I tried it on the computers.
Also tried a different usb/cig adapter - actually three and get the same results. Car only has 1 cig port.
Anyone have an idea?
I just started to have charging issues a few days ago. I have not changed my charging equipment and don't think it's hardware. I have tried a variety of wall chargers and cables - some Samsung and some not.
Here are a few facts (as far as I can tell, from testing).
USB connection (I almost never charge this way, but it's helpful in the car.)
- Charges fine connect to USB/Wall charger when phone is power down (completely off).
- Leave it connected to wall charger and boot and then it no is no longer charging (after it was charging fine while off).
- I did get it to charge after booting it a number of times. I don't know what triggered it.
- I made sure to hold the device steady while booting to make sure I didn't change the cable contacts
Desktop Dock (This is how I usually charge - in the dock while I sleep)
- Charges fine in dock when phone is power down (completely off).
- Sometimes starts charging and engages Daydream when put in the desktop dock
- If it doesn't charge in the dock, a reboot usual starts it charging/Daydream again
This sure sounds like a software problem to me, since it charges fine in both scenarios when it is powered off. Any ideas about any software or device settings that may block charging after boot? Any other ideas on what is happening?

Thanks. I have cleaned the port out and moved the pins toward the screen. it doesn't seem to have helped.
