My sister got the GT-I9305 a little while back. Usually, she takes quite a few hours to charge it fully, about 7-8 hours. However, recently, it got worse. The phone has been sitting at 37% for over an hour now, and it is still stuck at 37%! I've searched for other threads on this issue but they didn't really solve my issue. It seems really weird that the battery hasn't even turned for the better(or the worse) after over an hour.
Anyone has any insight on this? Thanks a bunch!
P.S. Everything was off except for Power Saving mode and the mobile signal.
use a different charger, cable, port
i own that phone and i have to say that the charger is very weak 1000mAh charger for 2100mAh takes a lot i currently use my nokia's charger it has1200mAh and that makes a huge difference,my friend's uses nokia lumia's or of you have a recent computer you might have a supercharging port that provides much more power,
Hi everbody.
I use 2 different chargers, one from my tablet BQ Maxell Plus, other from another cellular...
NEVER had issues charging my I9300, with stock rom or other one....very fast and until 100%.
NEVER used the original one, but looking at it, is a joke of charger.....
Values: All debitate 5V, and 0.1 and 0.2 Amperes.
You must take in consideration other factors like electronic heat dissipation, filtrate, stabilitie, etc,etc with it seens not works well with the original one....
Who says that bigger ins`t better?:good:
1000mah is more than enough, must be a charger /cable problem

you guys are using capacity units on a charger. Chargers don't have any capacity, they have current, which is measured in amps, not amp/hours. So S3 charger would be a 1000mA or 1A, not 1000mAh
Never had a problem with the original charger. Charge time more than decent

how can that have an effect on the charging current?
On some cyanogenmod 10.1nigthlies versions it has problem with charging takes forever with oem charger, i am now on sentinel rom 4.6 it has same problem. Just use usb port from computer or some media player. It charge to full in maybe 5 hours from usb port, i dont remember excatly.
I agree the S3 Lte does not have the same speed in charging as the 9300 I use to own even though the chargers are the same, even different roms don't solve the issue, need a custom kernel to up the charging current that was available with the i9300 to reduce charging times

I'm about to use a Moto Milestone 1 charger for OB but I'm afraid that it may harm the phone. Both phones are listed with MicroUSB 2. Any tips?
thanks
Don't worry.. it will work Ok, but OB charger has 1000ma, if you use another charger that has let's say 500ma (like USB) it will take 3 hours to charge the phone instead of the regular 45 minutes!
I use a samsung cable directly from USB, the car USB port, a samsung 5530 charger, a LG optimus one charger, and they all worked, with various degrees of effectiveness!
The most useful one is the car's USB port that, even if it cannot keep up with the GPS (it charges slower than the battery drains), it can keep the phone running with 10% loss every hour with screen activated and GPS at the same time! The problem is that I hate radio and don't use CD's that much, and usually end up with the phone depleted before I reach the destination!
Thanks man! Ok I'll check that "ma" thing. BTW is it written on the battery or charger?

Both places; battery specify working and standby V and mA, charger specify the V and mA provider
So you can use almost every different charger if the specs are the same, but be aware of this: don't use a charger with less mA since it can burn the charger
Ma - miliamps.
How many milliamps in 1 watt/volt? The answer is 1000.
I assume you are converting between milliampere and watt/volt.
I never had a burnt charger by the way, that would be very strange considering that the phone is accepting 500ma from the start (that is the USB output on any PC), and I even saw chargers with a power of 2W (SUPER FAST CHARGERS). The Motorola chargers are 850 ma usually, so it should work quite good!
Indeed, it's very strange to have a burnt charger and we don't need to go into an electrical discussion but that happens because of 2 possible things, very high-peak of voltage or prolonged use of under-voltage

Thanks. Printed on my Moto charger is 850mA so I'll rather use it for my OB next time.
BTW, currently I'm using a replacement charger for my OB with a name "super charger" printed "4.5v - 9.5v 800ma"
It's charging at normal duration in fact I'm using it for days. The only problem is that my OB touchscreen freaks out if I use it while that charger is connected. It's obvious when I run the multitouch testing app because touch points run all over the place. Touchscreen goes back to normal if I disconnect the charger. I tested that "super charger" to my milestone and the same abnormal thing happens to the screen. What causes it?
Probably it's something to do with high voltage... I'd avoid using it if something like that happens to my phone..
Usually the USB style chargers are pretty standard... the speed with which they work are strongly related to the power (Amperes) they provide, the voltage "should" be pretty standard!

Battery experts say to try and use a charger that's rated half the power of the battery.
So for a 1500 mAh battery, a charger of 850 mAh should be a better option than a 1000 mAh one.
Yes, the 1000 mAh charger would charge the battery faster than the 850 mAh one but it will decrease the lifetime of the battery faster.
Just for be able to post new thread. Sorry.
Hello, I don't want to start a new thread so I'll ask here.
The charger that came with my OB seems to be damaged. It was working properly until last last night. My phone detects the charger but it won't charge. Got powermax turned on and it automatically turned off when I connected the charger, so I know my charger does have issues.
Tried banging the charger last night, connected it to phone and started charging, woke up to see that it stopped charging 2 hours ago. It didn't even fully charge my phone. Now I'm charging it with my pc via the USB cable. I noticed that the touch screen goes wild when I use it while connected with the USB.
Now, I'm planning to buy a Galaxy S2 charger. Is it safe to use? S2 and OB has almost the same battery capacity so I'm considering it. Any other suggestions? OB ain't popular here in the Philippines so finding accessories is a real pain in the a**.
Fitted a Corby 2 charger and it seems like they use Mini-usb too. Haven't tried charging with it though.
My original charger also died... Now I use the one that came with my bluetooth headset
So I guess using the OB charger on other stuff is okay too. USB is always ~5v.
You need to test the charger with something else to be sure, though.
I had the same touchscreen freaking out problem with my old LG KS20, whenever I charged it. Like it was shorted or something. So it maybe a problem with the phone itself.

Ok kabayan, don't forget to share here the result after u try gs2 charger. I too am looking for safe alternative to my milestone charger.
Standard port - standard voltage
Don't even bother, if it has a micro USB it should be fallowing the same standard as USB for charging (5V)...
Of course test the charger for any adverse side effects like screen flickering or short battery life, and don't use it if something like that occurs, but because of the standardized voltage and the fact that usually phone chargers have between 500 - 1000 mA, 99% of chargers work...
I still haven't found any incompatible charger for my phone and I don't even buy a phone if it has a non standard Charging/Data Port... it's just stupid... so no Iphone for me!

Hello guys! I'm here for an update. For the past week I've been using a Corby 2 charger. And guess what, it works just fine! only downside is it won't charge it up to 100% (usually gets to 99% upon unplugging). And it charges the phone a little slower than the original charger. I always let the phone overcharge overnight to have 100% battery.

I'm not sure of the voltage of the I9305 but the more volts = faster charging but hotter and hotter means a shorter life for the battery but it should be fine, I would trade it for faster charging. For amps, I have no clue and please correct me if I'm wrong anybody.

I'm pretty sure that you are saying the opposite way.
You can use more Amp but not more voltage.
More Amp - charges quickly.

AW: [Q] Charge with 5V/2A..?
In principle, the battery would load faster at higher charging current when the battery is capable of fast charging. If not, could reduce the battery life. I believe according to the charging control of Samsung, a current limiter is installed that can always draw only 1 amp. So it brings no benefit to using the charger of the tab. It may also be that the charging control of the current is limited so that is not loaded. The phone should not be harmed.

Should be fine for short term use.I've used half amp one amp and one and half amp car chargers wouldn't go any more than two amps no need to..may degrade battery a little so what there cheap enough to replace lol..easy peasy.. I live in tents an caravans 24/7 use leisure battery's not problem with amps just volts..bless solar panels..
The phone take what Amp it needs.. No more than its made for. 2A is only what the maximum out is for the charger.
You could make a charger with 50A, the phone still dont take more.
The volt is the value that need to be fixed though.
All phones charged via a usb needs 5V, no more, no less.(Usb =5V allways) Most batterys now days is something like 3.7V. Correct me if Im wrong.
Any way, you need a couple more volts in the charger than the battery to charge it.
Answere=Yes.. go ahead and charge.

I have had an HTC HD2 and used it's charger to charge my SGSII and now my SGSIII.
The time taken to charge with that is about the same as the SGSIII charger.
The charging circuits on the phone are smart enough to know that you are charging from a mains' adapter instead of an USB output from a computer and thus adapts the current draw from the system.
I previously did tests on the HD2 regardsing charging times and even with bigger supplies that the 1A one from HTC, it did not charge any quicker.

That charging circuit is made to cooperate with the battery and the rest of the phone.
So only difference you will notice is slower charge time if you are using a to weak charger that cant deliver the right amp.
As mentioned earlier you could use a 50A charger with out any faster charging time. Amps is allmoust of no interest if its not to weak.
Look at electricity as water. Amp is like how many liters of water a sertain pipe could deliver. Volts is more like how strong the flow is. To mouch pressure will destroy the flower. But with Amps you could pretend that the flower demands a certain amount of water and it will not suck more just becaus it could get more.

We all know that charging with the stock charger is very very slow so i was wondering if i can use a charger that outputs A) 5.2V/2.4A B) 5.1V/2.1A C) 5.0V/1.2A these are all charger that i have which one is the best to use without damaging the battery ????
none, as long as the charger your using isnt weaker than the stock charger, it'll make no difference. Having a 2amp charger might produce more current, but the phones going to accept only what its programmed for, which is what the stock charger outputs.
Its safest to use the stock charger with the stock cable, and if your phones fairly new, don't worry, charging speeds up after a week or two.

Phone has power supply control chip that limits the maximum charging current (1A in case of HTC One). Unlike fast USB charging maximum charging current is not something that is possible to be changed from any software.
Is it just my device or does this thing charge super slow? I can't even get a full charge in a hour and a half and the battery is only 410mah.
Do you use original AC Adapter? I use another one now and I can get it charged in 45 minutes, which is ok to me.

Can someone tell me how long the actual charging time exactly takes ?
I use the original charger that comes with the device and it takes about 3 to 4 hours to fully charge the watch.
I find that quite long as I read the comments here.
The first tames it takes only 1,5 hours to charge it but all the other times it goes real slow.
A factory reset didn't help to resolve this issue.
Thanks.
As far as i remember battery have a capacity 410mAh, original charger have power output 700mAh, so charging time should be about 40-45 minutes max.
Change usb cable, if it doesn't help change charger (but it should have power output >700mAh)
PS. AFAIK using charger with power output >700mAh is harmless because watch limits charging current by itself.
Measuring charging time is best indicator.
Charging with 2.0A adapter will not increase the charging speed - the watchregulates the charging current, it will not just blindy "connect" the charger to the battery (in fact, I can't think of any piece of electronics that would have the charging logic in the adapter nowadays).
I had no problems with any chargers, not even with USB charging - the battery is very small, so unless you have a charger that can't put even 500mA you should have no problem.
I've seen an issue where the watch was "charging" constantly and ended with 85% and wouldn't charge anymore - reboot fixed that and it showed 100%.
I was thinking that your charge takes so long because you could have some process draining your battery in the meanwhile (that starts when you connect your phone, like a tasker thing or smt). Newbie thoughts so correct me if this is impossible
I could try to do a factory reset and see after that if it charges much faster then now.
For the moment i have a few apps on the watch, i do not know if it matters or not for to influence the charging time.
It's weird that we do not have the ability to load the watch while it is off.
From the moment that i put it on the charger it turns on automatically !
hello my friends.
the charging dock is limited to 0.85 A (850mA)
It makes not more sense to use a Adapter with 2.0 A Output. It won't charge faster.
Look if every pin on your dock is ok.
also the connection pin on your watch.
Try to clean a little bit with high percentage alcohol.
best regards
Problem solved by using another USB cable.
Now fully charged in 1,5 till 2 hours.
I haven't measured the charging time of my watch but it looks to me pretty fast. I guess with original charger 30 mins - 45 max, not a min more.

Hi,
that statement isn't particularly correct. The charging system in the watch (as with any LiIon battery) will draw as much current as is "good for it" and no more.
Just because a charger offers 2A doesn't mean that this is the amount of current flowing through the charger / battery!

Are you certain it`s not the app that is wrong as the S2 is new and the app might not have been updated yet, Try the Samsung charging app below, you have to keep pressing the refresh button on the free version.

The charging rate can be anything from 300mAh to the maximum the power adapter can output, the tablet will determine the amount of power it will accept, and will jump from fast to slow charge depending on how much more power is needed until it reach 100%.
Thanks guys - obviously does not seen to be wide issue.
I tried the Samsung app above ... Sort of showed similar values ....
I did a charge from 69% to full and it took about 1.5 hours... So would be maybe 5 hours to charge fully?? Unless the device does much quicker charging at very low battery??
I will do a full discharge down to say 5% and then charge from there and see how I go.

Normally it will trickle charge slow once it reach approximate 80%, and is normally fast if the unit is almost power empty.

There is another thread on this that I have mentions about this, just use a good quality charger, or just go for a Qualcomm QC 2.0 charger from any known brand like htc, aukey, xpower, lots to name, just searh Qualcomm site for a full list.
It won't used the QC2.0, but all should work just like the OEM Samsung one
the ipad charger should be pretty high quality though, so I don't get why it's being so picky.

If you also followed the tab S thread, it's also been mentioned, Samsung tabs S are also picky, and yes all apple stuff don't work.
Should I rephrase it and say some good quality charger will work, even branded ones like sony may not even work, but my intital testing, most QC 2.0 charger will work.
The issue is that I'm trying to find one charger that will charge both my tab s2 and my iphone 6+ quickly. Any idea how qc chargers fare with iphones? The bundled tab s2 charger only gave my iphone 0.4A (it charges the tablet at 1.5A)

Odd, my old Nexus 7 2012 charger fast-charges my S2 710 without any issue at all. I had it spare as the N7 died on me (the S2 is its replacement) and was initially wondering myself as I had a few supposedly 2A chargers at home which only slow-charged the S2 (or indeed under Android 5.0.2 said it wasn't charging at all, even though it evidently was, but 5.1.1 has fixed that).
That said this is a charger without fixed cable (but with a decent USB cable) and I know from Raspberry Pi experience that the cable is almost as important as the charger for getting decent charging (ie enough current) to the device on the far end.
I would make sure the USB cable is a decent one intended for charging.
Proper charging USB cables have the shield connected at both ends for use as ground which is why they are notably thicker.

I agree, a good quality cable is required, as well as the charger itself, I'm using a magnetic cable and a reversible micro USB cable with a OEM Samsung, Aukey and Xpower charger, I don't get the speed of the QC 2.0, but it isn't suppose to as the S2 is not QC 2.0 compatible, but it does charge pretty quick, it also charges my ipod 4, and my nw-ZX2 work without any problems.
I get the "slow charging" message when using the Galaxy Tab S2 bundled charger.
If I use the charger from my Note 4 (Exynos) I get faster charging and no "slow" warning.
Did Samsung bundle it with the slow charger??
I can confirm that samsung did in fact bundle the tab s2 WITHOUT a quick charge usb charger.
I also thought the tab s2 didnt come with quick charge. I have extremely slow charge times but my battery lasts for DAYS... I can fully charge it, put it in airplane mode and check on it after 2 days and be at 98-99% battery.
I also use the quick charge cable AND the quick charge usb adapter that came with my note 5 and the tab still slow charges..
Here the same problem use Samsung charger and cable charge from 20% to 100% in 6 hrs and when use HUAWEI cable with Samsung charger It charged in 2 hrs
I guess Samsung have poor quality cable *-*
