I9305 Taking Forever to Charge

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

right ^^ it's 1A and 1.2 A

Try disabling USB debugging if its on. Its in developer settings.

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

Charging Issues, special cable and charger needed

Just picked up this phone and I love it. On stock 4.1.2 I have charging issues where the phone will only charge with a very good charger capable of putting out >1A and a beefier cable.
Which rules out charging from computer and some shoddier chargers. This is a deal breaker for me.
I will go ahead with rooting and upgrading OS to custom, if someone can verify that this will be a non issue after completing that? Thanks.
Edit: further when streaming netflix and charging, the chargers can't keep up with about 30% screen brightness. Will also be resolved?

how many chargers don't output 1a or greater these days? im using a htc hd2 charger that's nearly 4 years old and a generic usb cable and have no issues charging the phone

Well for the second point I'm even using a 2A charger and and its charged 3% in 2 hours, with netflix, which seems more like a software issue.

and have you rebooted the phone? I had issues like that on my old galaxy note, a reboot often fixed it due to other processes and apps running in the background

I also am struggling to find a decent cable to charge my phone with.
The supplied cable charges it very quickly, but is a little too short to comfortably use the phone while it's charging.
I have purchased a couple of longer cables that seem to be of decent quality (24 awg), but the time to charge the phone fully increases dramatically when using them.
This is all when using the supplied charger.

Tried the reboot, still the same issue. I think I've realized the problem and it looks like software.
I have a kill-a-watt meter. With screen on, and netflix streaming, for some reason its only drawing 3.3W. @ 5V this is only .66A. Clearly too low to charge with. However when I turn the screen off, after a few seconds draw goes to 8.2W, ~1.6A. Now I'm not concerned with staying on the stock OS, however do people still have trouble with this on custom OS?

Sweird...I've never noticed any slow charging on my 6606. I've used a few old chargers from HTC , nexus and Samsung. My Motorola Bluetooth charger however doesn't charge very fast at all but I'd expect it not to.

Its not the best to use ur phone to much while charging tbh. It might kill u battery quickly and damage the phone itself.

charging note3

I usually have my note3 plugged into normal usb port on my notebook as i work to recharge it just using a normal micro usb cable.. i noticed that re-charges usually take forever and even after 2-3 hours of charging it only goes up only about 10%... is this normal ? my previous phone iphone 2-3 hours on a charger its fully charged.
is there anything i can do to speed up the re-charging like asus ai charger ? or anything else ?

Usb 2.0 is limited to ~ 500ma, the phone will pull 1.2a- 1.5a on the Samsung charger

The ASUS AI charger is for 3.0 only I believe, and your Note isn't compatible with that. I purchased one of the RCA plugs from Lowes that has 4 USB ports on it and has an output of 4.1 or 4.2 amps and using the 3.0 cable that came with the phone it charges it very fast.

Here's what I use guys. I used it on my Note 2, my brother's S3, my Note 3, and also my LG G Pad 8.3. It has about 1.8-1.9A charging capability and charges a little faster oddly enough than the 2.0A stock plug when plugged into the wall. Yes, it's a wall charger, so that's obviously the best way to charge. It's cheap and very convenient; the cable is actually quite long, which is much nicer so you have more room to move around when charging. You won't be disappointed. I don't advertise garbage products. I always look for the best quality things and share my results and opinions to help others. Before my Note 3, I had rooted my Note 2 and had Perseus kernel; I increased the charging values so I could utilize faster charging, and this charger was the best for that. I highly recommend it. I've had it for about almost 11 months. It has never given me any issues, and it has great reviews.

So what is the max that note3 will take?

hilarious jab at samsung

Idk if this is just for the vzw version of the g2 but anytime i plug it in to one of my samsung chargers that came with my galaxy nexus (when on the stock vzw rom), instead of going to slow charge mode it says something along the lines of it being a substandard charger and that i should plug the cord that came with my g2 to charge it safely then cuts the power. Has this happened to anyone else using samsung chargers? Or could it just be that it really did dectect something wrong with the 2 particular samsung chargers i tried?

The actual charger that comes with the G2 has integrated QuickCharge 2.0. Hence why you will notice much, much faster charge times.
Not many other chargers and phones have this capability.

I get that with a BlackBerry charger, too. It has to do with the amperage output.

Oh ok lol i thought it was a little brazen to just not allow your competitors chargers to work as all the other non samsung chargers i have at least will slow charge.

Yea i get that its faster w the stock charger what i was saying is that normally you get a notification when using a non stock charger that its in slow charge mode but with all my samsung chargers it wont charge at all, it shuts it off compleatly. I thought it was a Samsung specific thing but apparently it has to do with certain amperage outputs it wont let the phone charge with

You make it sound so special
It's nothing more than a high output charger. Plug it in an Ipad or > 2.0 AMP charger and it will charge just as fast, without the fancy "2.0" technology

Ohhh so thats why it charges so fast! Mine gets 15% up in literally 15 minutes lol. I go bed 21:45, at 22:00 its already beeping that its full back from 85% xD Great stuff really:good:

Yeah idk it seems like it does charge a lot faster, definitely a lot faster than my S III

This phone is stupid with chargers.
I have a dual charger, 2.3 amps and 1 amp. It fast charges on the 1 but complains about the other.
It complains about an HTC cable and cuts charging, but will charge normally when simply unplugged and plugged in again.

question about new wireless charger

i got the new (circular) wireless charging station from samsung as well with s6e. i was wondering if i can use the advance fast charging that comes with the phone on the wireless charger to have it charge my phone wireless faster.
or will it damage the charger?

I don't think wireless charging will be any faster no matter what 5v USB adaptor you use as the wireless pad will only put out a set current, but I used the adaptive fast charger that came with the phone and to give you a rough idea of it's speed it topped my Edge up from 24% to 97% in about 2 hours. Quick enough for me and way faster than my old Nexus 4 on wireless charging.

While we are on this subject, would it be harmful for the phone to be wirelessly charging and plugged charging simultaneously? Would it do nothing, charge even faster, or overheat and damage the phone? I dont plan on trying it, just curious.

I would imagine that once something is plugged into the USB port (charger, OTG or whatever) wireless charging would be disabled as a safety precaution. This has been the case on other devices and I assume the same would apply in this instance.

The new wireless charger from Samsung supports AFC (adaptive fast charging) and it works with the cable and power brick that came with it. Been confirmed online a few times and I can also confirm because it charged my phone from about 5% to 100% in under 2.5 hours. That being said it's still not as fast as just plugging into the wall.

Just so everyone knows how it works you can use either the charger that comes with the phone or in the box with the wireless charger. As far as it charging faster the way it works is 50% in 30 mins when connected physically to the wall. On the wireless charging pad it goes up 20% in 30 mins. Now the good thing about it is when the devices charging port goes out you can still charge your phone and it's faster then the old pad they used to use.

This makes little sense. If it supports fast charging, it supports fast charging. If it's "not as fast as just plugging into the wall," then it doesn't support fast charging.
Fast charging will get you from 5% to full in around an hour, not 2.5; which correlates with where wireless tech is right now. Because regardless of whether or not it can support the power input from a fast charging adapter, wireless chargers currently cannot utilize "fast charge" tech. The fastest wireless Qi chargers currently are 5V/1A chargers. That's as good as it gets right now and they're nowhere near fast charge spec.
So regardless of what you may have seen "confirmed" online, the Samsung charger isn't a fast charge device.

I am using a wireless charging and I would comment like "so far so good"
I think you should also try this. !!!

The charging pad for me is a convenience factor. The fact that the fast charging gets ours phones up to 100% in 1-2hours depending on who you listen too is already fantastic. I like the idea of just walking in my door at home and placing it on the pad. Who cares if it takes a little longer that plugged in fast charging. Enjoy the ability of just placing the phone on the pad when you get home and have things to get done right away. Can't believe so much negativity for a phone just released with no development yet such as custom ROMs and kernels to make a beast of a phone, a KILLER beast. Sorry, just too much negativity for me. I have owned every Samsung Galaxy all the way up to this Edge 128GB. Yeah, you can't remove the battery. Yeah, no SD card slot. But the Internal memory is so damn fast, I am no longer in that complaint department camp. As for people moaning that their rear glass magically broke all by itself...I have a hard time believing that. I bought a Spigen NeoHybrid case that covers the back with a nice rubberized well fitting cover. The edges of the case ar metal, so you still have that wonderful tactile feeling of a solid metal phone. Best Samsung phone to date, IMHO and once ROMs and custom recoveries come along, it can only get sweeter. In the meantime, I will get off my soapbox and enjoy a phone that far exceeds my S5 and happily wait for developers to do their magic. Patience is a virtue. Sorry for my rant if it offends those that expect perfection out of the box. Yes, it's a damn expensive phone. So are IPhones. And they had issues right out of the box and their OTA fixes caused worse problems. I rest my case.
EDIT: The help so far from users here in general have been fantastic and my hat off to thos that helped me deal with softbricking my phone from either initially using a root file that didn't work for our 925 models, to showing the way to use Kies to actually restore the full stock image, and to ZiDroid to actually give us the ability to at least have a working stock recovery screen instead of the dreaded black only screen after rooting. And I enjoy using apps that require rooting so as far as warranty issues goes, I don't really care. If I can Odin, Kies, smartswitch or whatever new stuff comes along, then I'm a happy camper. Other here just need to do a little reading and search before posting rants that have fixes already out there posted. Off soapbox again

S6 wireless chargin box doesn't include cable and plug in it. I will buy a new data cable and plug for it. Should I buy adaptive fast charging cable and plug which comes with S6 or can I use S5/Note 3 charger for it? I am asking cos S6's adaptive fast charging cable and plug is more expensive than S5 charger

In Turkey, they give it free with S6 edge as a promotion without cable and plug. What kind of cable and plug does it have? Same as S6 fast charger or classic S5/Note 3 charger?

That's probably why you just got the pad since it was a promotion. I bought both of mine through samsung mobile website and they came with white ones but not adaptive fast charging. The pad cannot charge fast with it anyways.
