How do you know when an Extended Battery is full charged?

I just bought an extended battery (the Sprint Store one) and when it stops charging, it doesn't show the number of chargness anymore and it doesn't show the lightning bolt on the battery once the LED light is green. So do I just leave it overnight to charge?

It will be charged by the time you wake up in the morning lol

You sure? It doesn't show the charging icon on the battery... And I doubt a bigger battery would charge that fast?

Why don't you download battery monitor widget its free and shows all stats.

Once you install it, just go into.settings and set update intervals to 60 seconds.

It will still reads the accurate mA's + and -, why not just check the stats and watch when it hits 0mA's.

Yes... SBC will get you maximum charge... if you don't use SBC then what you need to do is follow the instructions located here:

Personally, I love SBC kernels. I've never had issues with them at all and it works great with my 3500mah battery.

It will not pass 1500 unless you use sbc, the stock kernel will stop at 90% but say it's at 100% to prevent overheating. So technically your initial drain will be really fast cause when you unplug your phone its really on 90% and not 100%. My phone has never overheated or any weird issue you would expect to happen.

The ONLY way you're going to get full potential out of your battery is by using SBC kernels. HTC has a charging bug where it won't let you charge past 1500, so technically it will stop(go green) you at about 90% but shows 100%. Check out this thread with a bunch of kids using 3500 batteries; they're mad because they can't charge to 100% but if they use sbc they wont have that problem lol.

Here's some info about kernels/sbc
http://forum.xda-developers.com/showthread.php?t=894880
To flash a kernel you need to make sure you only flash a sense kernel for a sense rom and aosp kernels for aosp or you phone might not boot beyond the evo logo(nothing major its easy fix). You find a compatible kernel and grab the package and boot into recovery and flash it. I'd recommended wiping dalvik cache after flashing a kernel.

Here below is the direct link to the kernel that I would recommend for myn. Its the netatchy toast mod cfs with hdmi built in. Good luck

i dont know but its been a day and im still at 50% so i guess i dont need sbc

I have the seidio 3500mah extended battery and they recommend charging an extra 2-3 hours after it says full. I've found this to be true; if I pull it off right when it says full it will soon drop anywhere from 30-50% of the charge.

Yeah if its sleeping 80% of the time then I would expect it to last that long but not for heavy users.

I got two extended batteries. One in the phone and one on an external charger. I never use the cable to charge anymore. I just swap the batteries when my phone dies.
Sent from my PC36100

I also have the Sprint extended.
I see people saying that the battery won't fully charge without SBC. Completely untrue.
Also untrue is that the phone will not charge past 1500. This doesn't make any sense to begin with -- why would they sell extended batteries if they don't work...? Or why would they sell it if consumers needed a special kernel that you can only get if you're rooted?
Perhaps the reason the people with 3500 batteries don't get the full 3500 charge is because most of those batteries aren't even 3500.
----
You need to cycle charge it a few times and then you'll start seeing the battery life go up. I can get at around 2 days with light usage now.
----
Honestly you don't need an SBC kernel at all, though it might extend the life a bit. It's completely a preference thing...

Using Nexus 7 charger for S3 and vice a versa

Any effect on battery life or any other considerations to keep in mind when trading charges between different devices? Nexus 7 charger outputs 2A while S3 charger outputs 1A

I always charge my S3 using my Nexus 7 charger and have had no differences in battery life. Except charging is a lot faster.

Well if you do in fact see difference in charging speed, then why would not Samsung supply this kind of charger with S3 instead of 1A one? I assume this would be another feature to brag about (now charging twice as fast as ordinary charges or something). So I would assume it's either not true (placebo effect) or it's infact shall be having bad influence on battery. We need somebody with electrical degree probably to render final verdict.

BlackBerry has a rapid charger for the Playbook and they actually tell you there's no problems to use it on their handsets. I think the reason for not including it is that the price is so much higher - retail $50 vs $25. Same as iphone and ipad chargers.
I use my Play book charger almost exclusively with my S3 - and the Playbook has sat unused on the shelf for over 6 months.

Charging speed is controlled by the kernel, so you could technically charge with any charger in existence but the kernel will only allow the phone to charge at a preset amount. The stock charger is under this voltage cap so other chargers will charge faster, but as I said, it is capped. So I wouldn't worry about it.

As I said, the in box charger will not max out the phones charging speed, so other chargers can and will charge faster, to a certain extent.

I've tried with my OEM sgs3 and sony vita charger. The phone draws the same current on both. So yes placebo. And to answer if charging at a higher current is bad for the battery, it depends on the battery cell. But usually charging at a higher current does shorten it's life.

What about in reverse? Can I charge Nexus 7 with lower amperage S3 charger? Any ill effects?

I use a Motorola charger because it has two usb females
Sent from my SGH-I747M using xda app-developers app

As long as a USB charger puts out the required 5v it will do fine. The device will pull as many amps as it wants out of the charger up to the max capacity of the charger. If the charger cant put out as many amps as the device wants, the device will just charge slower at the lower amperage.
As slower charging heats up batteries less and stresses them less, this isnt a problem at all unless you are in a hurry. I charge mine at night and could care less how fast it charges.
Sent from my SAMSUNG-SGH-I747 using Tapatalk 2

Over drawing current from a charger isn't a great idea. Most chargers are designed to run at 80% max current for short periods if you run them higher they can do a number of bad things.

what in the blue hell is going on? (battery charge sucks)

so i tried charging my phone in different outlets, using my other family's charger, different cables, everything.
as of like 15 days ago or something, the charging is extremely slow (like it will take 8 hrs to COMPLETELY charge)
look at the graphs.
what in the world is going on here??? sometimes juiceplotter tells me that my wi-fi is on during the charging (which it shouldnt be since juice defender is supposed to turn it off when screen is off, but EVEN if it was on 100% of the time, the charging should NOT take that long)
but in most cases, the wifi is actually off so wtf is going on?

I use my stock charger at night when I don't care how long it takes to charge (it takes a ridiculous ~8hrs to charge). When I need a quick boost I use my old HTC charger and HTC cable. I think the output amps is higher but it seriously only takes an hour to fully charge my S III.

How long does your S 10.5 take to charge

Mine takes 6 hours to go from 10% to 100% using the included samsung charger and cable. That seems like a long time.

Mine takes 2 or 3 hours. 6 hour charge might are the chargers with slow charging. My dad has a slpw charger till he changed it. Have you tried changing chargers?

It's USB 2.0 so it's expected to be slow. The 3.0 port would have been bigger. Samsung sacrificed charging speed for aesthetic. To be the thinnest tablet they've ever made.

This is the first tablet for me and in effects.....too much slow on charges. Fortunately I use only at home. A part that....it's a bomb !!

Too long
I just bought a TAB S and using the included charger and cable it has taken 10 hours to go from 18% to 58%. The tab was turned off. TOO SLOW. Do I have a defective tab? Please let me know so I can return it.

DO IT ON YOUR OWN RISK! but i will recommend u guys to get the charger of say, Oppo find 7. or any ANDROID device charger which is more than 2A. it will be better. of course, better find samsung charger with more amperage.

Samsung Model EP-TA10JWE that the same as original one but it charge faster that the old one , I think Bcuz the original is old enough for me to buy new one

Mine charges exactly from 0 to 100 in 4 hours.

A full charge take around 5hrs.

That`s not a full charge 7900mah / 1800ma is 4.38hrs and it`s over 5hrs when you add the 20% charge inefficiency.

My Note II taking 12+ hours to charge, sometimes shows 24+ hours to full charge, help

My 3 years old Note II - N7100 is acting weird since few months, when I connect to charger it takes more than 12 hours to full charge. I connect it to charger overnight, and when I see in the morning it's just around 60%, it charges 60% in 8-9 hours.
But this keeps changing, few nights ago it charged only 20% overnight.
I changed my 3 years old battery thinking that might be a problem, bought Intex 2500mah one , same problem. Changed chargers, I usually use my Note 5's original charger but no use. I was using custom Rom - Eclipse,then flashed original Rom but still problem persist. I thought my usb port must be faulty so ordered usb flex from eBay and changed it, but didn't work, actually after installing new usb flex, my mic stopped working but charging showed same - 12+ hours time, so returned it.
So what you think is the problem? Should I buy new original battery or try another usb flex? I am frustrated. Sorry for long Question.

Try to test using a different cable... and also check if your adapter is working properly...
most of the time the cable is at fault...

Install app galaxy charging current and see what current your charger and cable is giving should be around 1500. Most of time cable and charger is at fault. Hope it helps

I had the same problem. Mine solved by charging the device couple of times while it's off. Now the device gets charged in 2-3 hours.

Problem solved, after trying everything changing cable worked. My note 5 cable charges my note 5 fast but same cable takes 20 hrs to charge note 2, combination of note 5 adapter and gionee cable worked. Now it takes around 2 hours to full charge my note 2.
