Hi,
I got a new S3 mini I8190, unlocked sim free, 8GB. I plugged it into my existing USB charger (single port 750mA, Sony) while it was switched off and it charged to 100%. All fine. So, I set it up with sim card, SD card and apps and then charged it again, this time the phone was switched on. It appeared to be charging fine, but the charging topped out at around 87%. It wouldn't go any higher. I tried a load of testing, killing services, switching off wifi, using a different battery etc etc. However, it turns out that any USB charger will charge this phone, but only up to a certain level. So a 500mA charger would only take it to around 75% charge. The charger that came with the phone (rated at 750mA) fully charges the battery as does a 1A supply I have.
Question, is this normal for this device or have I got a duff phone?
Thanks in advance,
Niall
i also have a 500mA charger. charge to 100% but it's taking almost a day to complete if the device is on

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)
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.

I am having a problem where charging is beyond slow when using this cable. It will charge 50% in 8 hours.
And if phone is in use it will discharge while plugged in.
When i switch back to original cable that came with my note 2 it takes 4h or so to fully charge my battery.
Anybody else have tested this or similar cable?
I no longer need it since i got my zero-lemon battery but it would be good for my wife on her S3
Is there a tested alternative someone can recommend?

Mine too, too slow. Check the current with: Galaxy Charger current, get from play store. Only 400mAH.
and,
I bought one which LED, 1 meter, it can not charge. 0mAH.
:crying:
The longer/thinner the cable the slower the charging will be. Its best to always either stick with OEM or verified manufacturers for chargers and cables
Hey guys,
I haven't used my Galaxy Tab S2 in a while now. When I plugged it in it was at 0%. I used "a" (possibly not original that came with box) OEM 2.0A Samsung Charger + Note 5/Samsung Official Cable to charge my tablet. It has only gone up by 5% in the past 30 minutes.
Also when it was at 0% it said it'd take 7hr 12min to fully charge.
Is this normal when the tablet has not been used in a long time, or am I possibly looking at a bad charger/cable as the charger and cable charge my Note 5 just fine at the normal (non-fast charge) speed where it charges my phone fully in just over 1hr 30 min.
If someone could help me out to resolve this I'd be grateful.
Thanks! :laugh:
Don't think the charger and cable are faulty as they work on your mobile. Generally whenever I charge my Samsung galaxy tab s2 using a different charger it shows a notification if the charger plugged in is slow. If it didn't show this I don't see why it would take so long other than the charger your using has a lower output causing it to take a lot longer than usual to charge.
Every android device I have will sometimes not charge fast enough - it doesn't matter what charger I'm using. If I catch that the charge is slow I just unplug it and replug it a it'll be normal again. I think the "smart charge" goes crazy sometimes.
I had the same problem on the tab s2 8''. It was because the motherboard broke. They fixed it under warranty.
When I had this problem I couldn't attach any external device (usb, playstation controller) through USB. Try if you can
I don't have the original charger anymore to compare on my 9.7. I use anker potable batteries to be free of wall sockets. It isn't 2.0. In battery monitor widget, really good app, shows charge anywhere from 1200-1600mA 20% per hour while in use during charging. 5 hours total. I think with screen off I get 30%. I get 10 hours of screen on time zero loss with it off over night. Using 5.1
It could be the motherboard. I know with laptops charging starts to mess up a few weeks before it no longer works at. The connection between the USB and board weakens over time/use.

Sounds normal. The big Lion batteries in these devices are just weird at time. Running one down to 0 is a good way to kill the battery permanently. Let it charge slowly and then keep it above 20-30% from now on. Should improve over time.
I think its a myth you shouldn't let the battery get low. As long as the battery itself says I'm at zero at the correct voltage then zero is perfectly fine. I'm not an expert here but at 5% battery I'm at 3.6v and will turn off in a few minutes after that. I think batteries are manufactured to safely go down to 3.2 before saying no more. Need to charge.
