[Q] Battery recharge time?

is normal to take more than 4 hours to charge up to 100% the battery?
Case i think that is to much, are faster ways to recharge the cellphone?

Use a charger with more power....an iPad charger provides 2a current nd 10 watts power...it should reduce charging time...while the one with the note gives 1a....

Using a PC port? Computer USB ports only output 100 ma. We have a 2500 mah battery. So you're looking at at least 25 hours for a full charge.

Like i said before...buy an ipad charger...

As far as I know, according to USB specs, it should have 500mA. (5 hours charging time).
I believe that there is a charger provided with the Note that is at least 1000mA.

And the note Suport that charger?

That's right, yesterday i ler it charging while doing a benchmark, in the pc it loses 2% and hardly came to the same Power that before. Out in the samsung charger it's much master, i dont have lose any power at all.

Use a more powerful charger.

Any USB charger that plugs into a wall should output much more power, generally up to one amp. Any USB charger should work.
I use the one that came with my mytouch 4g because it is tiny.

My iPad charger outputs 2.1A, the Samsung charger only outputs 1A. Since the Note's battery is only 2.5A, it will be fully charged within 1 hr and 12 mins with the iPad charger. Using the standard Samsung charger it will take 2 hr and 20 mins.
Using an USB-port it would take you approximately 25 hours since the USB-port only outputs 0.1A. There is no way to draw more power from this port, since it's the 'safe' limit of the USB-circuitry.

thanks i have buy it today, and now i am going to test it.
Later i will give you a feedback
After 1:30 Min is about 50%, do you think the 2,1 amp's aren't being used?

It's not - but you really wouldn't want to charge that fast. It's not good for the battery.

i know the limits of the amperage but they are not put by me, any usb 2.0 cable is good for the job?

finally i get 100% after 3 hours, is that a good result?

Should be OK. My phone usually takes 3 hours to charge as well.

thanks, i tough that the phone has some problem.

2500mAh/1000mA = 2.5Hrs.
But I think the charge curve for lithium batteries isn't linear, the amount of juice near the end is reduced by the controller, so all in all 3hrs for an almost drained battery seems reasonable.

[Q] How long does your tab 8.9 charge?

How long does it take your Tab to charge from about 0-20% to 100%?
It takes mine forever - about 16 hours, although I'm on stock Honeycomb rom

I'm not completely sure, but 16 hours seems to be too much to me. I usually charge over night, so i guess it might be something around 8 hours.

I think so too!
I just wonder what is causing this... (1) some faulty chip in the tab itself, (2) faulty battery, (3) faulty Samsung cord or (4) faulty charger. No way to find out for sure, unless I return it to the shop and wait about 30 days (at best) while they figure that out and give their verdict
I hope someone has\had this problem and knows what exactly was causing it.

the last 5% take forever. That's usual behaviour for charging. Check out how long it takes to charge to 90% or maybe 95%. Should not take longer than 6 hours. If it does then maybe try a different charger or reset your tab to make sure it's no software bug.
Hard to tell the real source of error, sorry...

Are you ABSOLUTELY certain to be using the original, for your tab, charger, with a 2 amp output.
With such charger, it should be about 4 - 4.5 hours.
But if you are using a generic, or something made for an avg phone, with .5A output... Well 16h seems normal

I am using Samsung banded charger that came with the Tab.
Sometimes it does charge fast, but most of the time it either charges very slow, as though it were charging from USB, or doesn't recognize the charger, or even says it's established MTP-connection...

from 8 to 10 hours on hc 3.2
but now on ICS take less

using the charger that came with the tab, you should get charging times around the 4/5 hours. HC 3.1 and 3.2.

Does the cable work properly when you use it for USB operations (file transfer, etc.)?
If so, then maybe the charger is broken/faulty. Samsung (in its infinite wisdom ) put a resistor network in their chargers so that the tab/phone can recognize a charger vs a usb connection ... or maybe just to make money from over-engineered accessories. who knows? However, if that resistor network has failed (or the cable is broken, hence the question above about USB operations) then the charger will present as a USB port rather than as a Samsung power source.
Oh! Another data point to consider: does gently wiggling/straightening the cable when it's connected cause the behavior to change?

There isn't much difference with ICS 4.0.4 US rom in my opinion. And it is still picky what chargers it accepts when it's turned on (DX.COM charger works for me). I usually turn the TAB off and use a stronger charger, but it still takes a LONG time to charge in my opinion. I do an overnight charge as much as I can.

Did an overnight charge with the Tab turned off, and it charged to 100%, finally. But when it's on (even in airplane mode) it only charged to 60% last night (took 12 hours!).
Weird)

i always charging my tab from 0 or 2-5% to 100% either when powered on or off and it always takes 5 to 5 1/2 hours. no more and no less with default charger set.
first i thought it was taking too long but when i saw this thread i'm glad its only 5 hours

Common belief (knowledge) is that this is not the best for a lithium ion battery... It increases the wear, gets it to lose capacity sooner... If possible, charge your battery often, like as soon as you can below 75%. Only occasionally drop battery to 0%. IIRC, there's a good website called "battery university" talking about that

Thanks, used your post to fix mine. I ended up replacing the cable and not the charger. I'm using an original charger with a new cable now.

I am seeing same problem with my brother's 7300 tab as well. Its taking around 10 or more hrs to charge.
Anybody got tablet replaced in warranty for the same reason? Even with Nexus 7 original 2 A charger its taking too much time. With samsung original charger also it was taking similar time so i am sure problem is with the tab only.

4-5 hours on mine.
Sent from my GT-P7310 using xda app-developers app

Many Galaxy tab 8.9 owners have reported experiencing long charge times to the tune of about 16 hours, me included.
Solution:
Plug in the charger to the tab very very slowly. The charge icon in the system tray has a lightning symbol on it aka normal charge.
Connecting it at normal speed results to the charging icon in the system tray having a cross on it. It then charges very very slowly.
Why should we need gymnastics to normally charge our tablets? Ask Samsung.

Charging Questions for Z1s

Couple of questions.
1. Anyone notice when using a magnetic charging cable that the phone charges at literally half the speed that it does from using the regular usb cable?
2. Does the magnetic charging doc that was made for the Z1 work with the Z1s?
3. Does it charge super slow with the magnetic charging dock too?
Sent from my C6916 using xda app-developers app

1. Yes, because your magnetric cable is not original. Many of this cables make problems because they do not respect Sony Specification. Mine for example charge 10% in 1 hour. Some of them working well, but is just luck.
2. Not sure about that but I think you can. I don't think they made a different everything in Z1s.
3. No. I got Original DK31 and in less than 2 hours my phone is fully charged. But if you buy not original one you can face this problem.

No I was just asking so I could just use the magnetic charger instead of the cable, the cable takes me like 3 hours to charge unless it's because I plug in the charger with the surge protector thing I have plugged in with my computer. Cause when I charge the phone with just an outlet, not attached to any surge protector or the such, it seems to charge faster but it's probably just me, but anyways if that dock does charge in under 2 hours I will get one from the Sony website lol.

I use the Stock Wall Charger 1.5mAh to 5V with the Original Dock. I spend like 26 euros for a best magnetic cable possible on eBay and it charge 10% in 1 Hour, Unbelievable. BTW, 3 hours from computer is normal because the mAh output is less than the Wall Charger. Next time I will buy original only or I will check the functionality of the cable and if it not working like it should I sand it back. Now I can't because i thought it was fine, but is not.

I wasn't clear my mistake, I meant I had the charger plugged in with the block plugged into an outlet extension( the thing where it plugs into one outlet allowing 5 more things to be plugged in through that one outlet) with my computer also plugged into the extension outlet also, but my phone takes 3 hours to charge, but when I charge it through the outlet alone not into the extension it seems to charge faster.

Thanks for the help, I will look into Sony charging dock or magnetic charging cable. Think mine does like 8-10% in an hour... But my phone charges much faster with the usb charger that came with the phone. 3 hours tops and my phone is charged. I'm trying to preserve the flap, so may have to spend more and go straight from Sony, instead of Amazon.

If you buy a DK31 go to Sony. Well spend money and no problem at all. The magnetic cable it's expensive but not original one do not working like they should.

Actually its not the Phone's issue but the Chargers'
I am using my Lumia's charger and phone gets charged in a hour from 0-100%

I will have an answer for this in a few days.

Theoritically it should take 225mins to charger from 0-100% with stock charger..
Anyone knows maximum charging rate?

Just did a full charge (0-100%) without the OS running. Took 2 hours. I'm using Anker Power IQ 40W 5-port desktop charger and Moto's USB cable.
Remember, quality of the cable (as well as the charger) directly affects charge time. So try to use official or high quality cable and charger

Mine also takes almost 3 hours. That is because they have given a 500mAmp charger . I am using my iPad charger block rated at 2.1A and it charged from 25% to 100% in 70 minutes

Yep,
Use a 2 Amp charger and you will get full charge in 1.5 hours.

[Q] Slow charge?

I'm using the "fast charger" that comes with the phone, but it seem to charge slower than I predicted. It says 1 hour until full charge when they phone is at 55%.
Is this right?

did you use the cable that come with the phone?
not all microusb cable can do fast charge.

Yes. I'm using everthing that comes with it.

The next question is.... were you messing with the phone while it gave you that estimated 1 hour left to fully charged? If you have the screen on and doing a lot of crap with it, of course it will take longer (this may be obvious to some, I'm not trying to insult you if you didn't know this, just stating the fact)
My experience with it went like this yesterday - note that I haven't even unpacked the factory charger, was using the Motorola Turbo Charger for this "experiment"
0% (phone died over night off charger to make this test)
30 mins on Turbo Charger - 45%
1 hour on Turbo Charger - 85%
Had to take it off to go to work, but those are some great numbers for a charger not necessarily designed for this phone, but the device was in Fast Charging mode the whole time, of course, so it was comparative

Is there some way to turn on fast charge? Because 6hours to fully charge or even charge a lot I don't have.

Use the fast charger that came with it or the Turbo Charger and it comes on automatically, 6 hours was with me using wireless charging which is always going to be slower than any wired 2+ amp charger will do

Lol I plugged into the the stock charger from the box and it said 6hrs to charge (from 0) switched outlet just incase that outlet was wonky but same result. The I said screw it and just figured I use to wireless charger so at least the phone would be near me, low and behold it says 3hrs (from 0). So apparently wireless is the way to go.

You must have had something else going on with the phone for it to say 6 hours on the factory charger....... I don't remember what mine said because I plugged it in, powered it on, and started watching the clock in the kitchen, turning on the phone screen only to check battery levels at those specific intervals I stated! I didn't even touch the device to start anything when I started this experiment, so it wasn't running any apps other than Android system level stuff, but no, wireless definitely isn't going to be faster, despite what the estimated timer said on the phone!

Well it's charging super quick compared to that factory charger. On the factory charger (plugged in right after phone died) went from 0 to 5 percent in about 25 minutes. on the wireless charger right now its gone from 5 to 16 in under 20 minutes. more than twice as fast.
Aslo, I am using the new Samsung wireless charger that is supposed to support fast charging.
**EDIT**
It charges even faster if I plug it directly into the cable for the wireless charger. Now it says 1hr29mn instead of 2hrs.

Make sure the cable is plugged all the way in to the charging brick. If it's not plugged in all the way, even a few mm, it will charge much slower.
