I was charging my galaxy tab while it was off to try the honeycomb rom. It showed around 8/10 and jumped to 9/10. Then I removed the cable from the wall plug and plugged the usb in my computer. The tab showed the charging battery stuff again. This morning is zeroed my battery to get better monitoring results. Then I unplugged the USB and opened my tab. It showed that the battery was 99% full. So I plugged in the charger again and in about 3-4 minutes it said the battery was charged. I plugged in the usb to backup data.
Did I kill some of my battery?

Hi,
My kaiser has been running fine, i installed a couple of apps this morning and all of a sudden my battery drained from like 70 - 80 % down to 15 %. even though i have plugged the handset into the charger the battery continues to discharge. I have uninstalled the apps from this morning but i have no power left in my kaiser and awaiting some charge to check if this has made a difference. Does anyone have any ideas?
Thanks
Still no luck after uninstalling some programs. Any advise would be appreciated.
Thanks
Does the phone charge at all? Did the phone ever indicate that it was charging even though it wasn't? When you were attempting to charge it, was it through a wall charger or through the computer? If it was the computer, make sure that "When device is turned on, do not charge the battery when connected to the PC" check box is not checked.
I wouldn't rule it out as a software only issue. If you were doing everything correctly, and it still wasn't charging, then there could be an issue with the charger, the battery, or the usb connector on your phone. I had unknowingly damaged my connecter before, and when I went to charge it, it said it was charging but in reality it wasn't.
Figure out... A long story!
I bought a vehicle charger for my beloved Xperia X1. Suddenly, the fusible of the charger blowed.
I tried to charge in my original charger AND in PC USB and the phone showed AC indicator. But the battery was still being drained until it finishes.
Checked battery and it was in 3.7v (it should be 4.2v). So, o plugged the USB power straight in battery, to send 5.0v. Charged just a little bit, turned on the phone, then it was dead. Forever.
Ok, I bought a new battery. The stupid seller from MercadoLivre (Brazilian eBay) sent me a BST-40 (3.7v) instead os BST-41 (original 4.2v). Wasn't the same size, but I made the connection. The phone turned on!! Amazing. But, altought It was plugged in wall charger, the battery keeps draining.
I ordered a external charger and a new battery. It takes 15 days to arrive =/.
So, someonde could (PLEASE) use a voltimeter and measure the voltage from PHONE without Battery and PLUGGED in original charger? Mine is telling now 3.325v.
I'm still hoping that nothing happened to my phone...
Is there any difference between (USB) charging from computer (Laptop) and charging directly from AC adapter (Samsung provided)?
Because, I was using my phone more than two month with SetCPU for more batter life, and I was able to use 3 or 4 days. But just yesterday I charged from my laptop and was full 100%. But after 21 hours I got 15% battery renaming. It’s seems like drain battery after i charged from Laptop. Anyway I will try to charge today from AC adapter which is Samsung provided with phone.
May I know if any one experienced this.

The only visible difference should be in charging time - AC adapter should do it much faster providing the current of up to 1A (1000mA), much less then that to be expected from PC USB port.
I'd rather search for some rogue app draining the battery, maybe betterbatterystats would be a good place to start.
there wont be any dfference, the battery will get a charge from either but usb as mentioned wil ltake longer to charge
if i got 21hrs from my battery i would not be asking ANY questions!!..

USB ports are low power
your wall plug has a higher output than your computer USB port
PC USB = 5v 0.5amps
wall plug = 5v 1amp
so a wall plug will charger faster.
use SetCPU governor, I am sure you will get 3 to 4 days (moderate usage). same as mine.
My final finding; If we charge through PC-USB, it will take time to charge and same time, will discharge rapidly. because I charge my phone yesterday with AC-adapter and now my batter level is 13 hours with 95%. While I charge from PC-USB it was 20 hours with 15%. (all time are in moderated usage, and no any apps are not installed during this period)
I don't know how this, but this is my experiences.
I get the same results that's why I don't charge it through my usb port.
I agree with your conclusion that low-power charging just doesn't last on the Note. I was travelling and mistakenly took the wall adapter for my Plantronics BT headset instead of the Sammy adapter. It charges basically at the same rate as the computer usb. It took forever to charge, which was expected, but drained EXTREMELY quickly (10% / hour with almost no usage). By the end of the trip I was keeping it plugged into the charger whenever possible.
Back home on my original charger the phone is behaving like normal again. (84% after 8 hours with BT on and about 20 minutes of talk time / display on)
I had Recently received my desktop pc from the repair shop and i plugged it in and wanted to transfer some files..
When i did so my phone's display went off!
I immediately unplugged my phone from the computer and it appeared to be working fine. Afterwards i plugged my phone into the wall charger but there was no light and it did not charge! But once i switched off the phone with the charger plugged in the light next to the port turned on! But it did not charge! I kept it like this for an hour or so but it did not charge! But if i unplug it and put it back in when it is off... It switches on but does not charge! Right now the battery is completely drained and is not accepting any charge..
I believe this is because of some current overload in the front ports of the desktop. I tried to plug in my PSP to it through the same ports and it too shut down but is still functioning...
I am running Ultimate ICS 1.0
If you dare to you could try supplying the voltage directly to the battery contacts.
Grab an old USB Cable - get rid of the plug that doesn't fit in your charger and stuff the red (+) and black (-) wire in between the battery and the connector.
DO IT AT YOUR OWN RISK!!!
Hey guys!
My phone will charge battery only sometimes. The PC usb is not charging the battery (but it does see the usb), my ac is not charging also. I bought a new one. not charging. I tried with 3 different batteries - not charging.
It only charge sometimes when im using the galaxy s2 mini charger. But then it charge ex to 50% or 80% and it stops. I get the charging animation but the battery power drops normally like if i were using the phone.
I opened my 9000 and tried to see if the usb charger is burned or the soldering is bad. But everything is all right :/
By mistake, when i was "rebuilding my phone" i put the simcard backwards. And then even with the mini2 charger i was unable to charge more than 1%.
Do you know what can cause it? Its not the custom rom (helly bean) because i did not update it when it happened a month or so.
Thanks for any help.
