Taking long to charge - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Is any one else having this problem. It takes my phone 6hours to charge to 100% using the provided charger.

That's how my One was and was one of the main reasons I switched to the S4 Active. No such problems here. I forgot to charge it last night and tossed it on at 8am with 40% on it. By 9:15 it was full.

I find its always best to turn off Wi-Fi, Bluetooth, data, and sync when charging to get the fastest result.

More then likely its just a short in my cord, but was curious if any one else had the problem
Sent from my SAMSUNG-SGH-I337 using xda premium

this is likely a problem with the cord or adapter. your device should be charging much quicker than this. have you tried another cable?

Even with everything turned on it should not take that long. For the whole 6 hours did it say it was charging?

New MF4 international ROM? If so it charges slow with screen on. Still shouldn't be that slow though. Download Galaxy Charging Current lite and see if the your getting between 1200 and 1900 mA

The s4 is probably the fastest charging phone I've ever had.. It charges to full from any percentage in about an hour.. Maybe bad outlet?

I checked the continiuty in the wire and was getting a lot of resistance. Bought a new cord.

It's supposed to do that.
It doesn't charge up to 100% to preserve the battery's health, it's designed this way.
If you really want it up to 100%, you can always bump charge it.

Also to note. Bump charging can cause problems, so read that to decide whether or not you want to do it.
Oh ok thanks..so just leave it at is? It bugs me but I can live with it lol

Also is it bad if I leave it plugged in if its at its highest charging point

Charger output

As I was putting my S3 on charge last night for the first time I noticed that the output of the new charger is 1A as opposed to .7A on the charger for the S2.
As the S2 had theoretically two charging modes, 450 &650mA (depending if it was enabled in the kernel..eg Siyah), I was wondering if any of the tech guru's out there would know what charging rates does the S3 accept (if kernel enabled of course) ?
I'm guessing this would have to be done with an ammeter but if anyone has any theories feel free to post here.

Hopefully GM of SiyahKernel fame will have an answer and tweak for us in no time in his upcoming kernel. I'm sure it'll be in his to do list somewhere.
Edit: First charge 4-100% in 3 hours.

1st charge got 4328mV.
Expect it to be a little more after a few full uninterrupted charge cycles.
Suppose I could do the maths and calculate an approx charge rate, but will need a true min. for that. Brain's a little tied right now though

ah , 4328mv ! im getting something closer to it, will get better with some more battery cycles.

Extended Battery Finds?

So, now that I've realized and begun the painful process of accepting my battery won't make it until my bed time (11ish). Anyone get a good find on an extended battery. Preferably one that doesn't require added bulk. A 2500 mah that fits the stock slot would be soooo nice
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Also interested in this. The phone is so thin a bigger battery might not add too much bulk anyway. Any word on official extended battery?
Just buy a spare battery.

Nope, I went through that with a captivate. Not gonna keep switching, its too much work especially with a case
Sent from my SAMSUNG-SGH-I747 using xda app-developers app
Do a search in this or the Q&A forum. There was someone who found an expensive one but he was getting something like 40 hours usage! The battery comes with its own battery cover that will replace the stock cover.

Extended batteries are nice, but you can never find a decent case to fit one. I'll go through the trouble of pulling off my case to pop in my spare battery. :cyclops:
There's already a thread on this in q&a which is where this belongs. Maybe a mod can merge this

you shouldn't have a problem downloading a 1 or 2gig movie within 30 minutes to an hr, it'll drain your battery half way regardless of kernel though.
If you're worried, you should stop pirating or Johnny Law will be on your rear. jkjk
To answer your question, just use it without connecting to the charger. Also, calibrating the battery is not necessary either.

So draining the battery regularly doesn't hurt it?
So in conclusion connecting the charger hurts the battery?

Keeping your battery at 100% all the time (letting your phone plugged into the charger) is literally the worst thing you could possibly do to the battery besides overheating it.
If you want to get the longest lifespan out of the battery, keep it between 40 and 80% and under 40°C (which is why the N4 starts throttling itself at 38°C)

Of course it will. It's a battery. They only have so many charge cycles. You can always buy another. With a little effort the battery can be swapped out.
That's right anyway I just wanted to know the least way I can damage the battery while downloading. ..do u have a suggestion

I can't give you advice on how to make piracy less damaging to your phone. That's against the rules.

I just had my lawyer answer a ~1800 euro claim for some song that had magically found its way into my torrent downloading software. He charged me 208€.
Don't download pirated media..
He never said he was downloading copyrighted material... plenty of legal Ubuntu torrents available and last time I checked that's not piracy

I should download until the battery drops to 40% and then recharge it

Haven't used wifi on this phone due to T-Mobile's 40mbps LTE, It's literally impossible to blow through the whole battery in a day unless the screen is on for 12 hours. Generally it's around 60% battery when I go to bed after being off the charger for 14ish hours after a heavy use day.
Its worth acquiring the Korean model. F320K. It comes with 2 x 2600 mAh batteries and a docking station that allows the batter which is not in the phone to charge independently. It also has a microSD slot supoorting up to 64GB!

What networks can it run on?
http://www.gsmarena.com/lg_g2-5543.php and all versions of the phone have all these bands I believe, the Korean versions have LTE A as a bonus.
