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.
For those of you who have tried the wireless charging mod for the T889 version of the SGN2, do you get a voltage drop across the receiver coils with the phone not charging on the Touchstone but powered up? What about NOT charging but powered off? I'm just wondering if the missing hardware controller shuts off power to the receiver coil when the phone is not in wireless charging mode. Do you notice a drop in battery usage time or no drop at all?
Anyone have access to the N7100 version that can verify this?
I'm contemplating applying this mod, but I also want some control over when the receiver coil is active. [I was hoping to post this under the developer thread started by Vinas1, but don't have posting rights to that area yet. I need to pay my dues with 10 posts]
Wireless charging is not much current. I think around standard usb current which is 500mah. The stock charger is 2000mah (2amps). So that means when in wireless charging if you have the screen on it will most likely not charge but keep it at whatever percent it is currently at. If you are doing anything else as well like GPS you can expect it to drain on wireless charging.
I always use a HTC usb cable and iPad charger for my note 2 and they work perfectly.
But today when I use them to charge my note 2, I find it charging very slowly.
I check the batter status and find it is USB charging while I use the wall charger.
I plug it out and plug in again , the problem remains.
Resolution: When I restart my Note 2 and use another cable , it turns back to AC cable.
But I don't know which one is faulty? My phone or my cable?
My phone: stand by for 17 days and I didn't charge it cuz I only use this to answer phone calls.
My cable: no physical damage and use perfectly before, though I use it with other devices.
what's more: After I use another USB cable , I try the previous one again and it works well ...
I don't know why.
Is it happening to you guys as well? Is it gonna harm my note 2?
I have the latest nexus Qi charging pad along with this USB car charger
http://www.amazon.com/gp/product/B0088U4YAG/ref=oh_aui_detailpage_o06_s00?ie=UTF8&psc=1
its dual port and has one for apple and the other for non apple phones.
the non apple port has 4.2amps output max.
it charges my Nexus 5 and Nexus 7 easily and fast and shows as AC charging.
the first few weeks i was able to use this car charger with the Nexus Qi charging pad no problem but now it doesnt work and the charging pad shows a RED LIGHT which means its not getting enough amps.
when I plug that car charger directly to the Nexus 5 and 7 it still charges as AC easily and fast no problem so it boggles my mind why it just stopped working with the charging pad.
What USB charger are you guys using that is still working with no issues with the charging pad?
Anyone?
I don't use it regularly with the wireless charger but I have tested it and it worked in the past...
http://www.amazon.com/Anker®-Dual-P..._18?s=wireless&ie=UTF8&qid=1406656736&sr=1-18
For some reason the black model is no longer available from Anker, so it's very expensive compared to the white... hopefully they get it back in stock.
Charging pads only need around 0.7 or 0.8A since they only output 0.5A so you don't need anything special for them.
