Mine is 5.3V / 2.0A. Why it is too small output current?
My Galaxy Note 3 also has charger with 2.0A output current, while its battery is only 3200mAh.
Our Tab S 10.5 has a battery with 7900mAh, but the charger output is the same.
That's why the charging time is too long (approx. 5h), while the charging time for Note 3 is only about 2h.
Do you guys have the same 2.0A charger?
Everybody has the same charger whether you have the 8.4 or 10.5. just the plug vary s
John.
Thanks for the info.
While the Note 3 has the 3200mAh and the 2.0A charger takes about 2h to fully charge,
our Tab S 10.5 (7900mAh) will need 5A charger to fully charge in the same interval 2h.
I know the 10.5" has an maximum charging rate of 1800ma, so using a more powerful charger will make no difference.
You can use the app below, to see your charging rate, maximum is the fastest you can charge at and does not change, average is what i look at, leave it for a while to get a good average , you have to press refresh on the free version, the paid version does this automatically.

I noticed that when I charge my Note 8.0 with the USB wall adapter that comes with it, charging only takes about 2-3 hours but when I use the power cable of my Samsung Galaxy S Advance, charging can take up to 4-6 hours.
Assuming that I don't mind the longer waiting time, will using the latter power cable to charge my device shorten its battery lifespan or damage it in anyway? Thanks!
Addtional details:
I'm guessing that the difference in charging time is due to the difference in current. High current contributes to greater heating, which damages the battery but I'm wondering if higher temperature over a shorter duration or lower temperature over a longer duration is more damanging. Is the difference even significant?
I've read this link How USB charging works, or how to avoid blowing up your smartphone from "is it safe to use any usb cable to charge s3?" and got the idea that my device isn't going to blow up or anything like that. I just want to know if it damages the device because I've spent a good fortune on it and I want it to last for as long as possible (hopefully a minimum of 5 years). Yes, any other advice on how to prolong device lifespan is also welcome. Thanks a lot guys!
The reason its taking longer is its not providing the same amt of juice the note charger is. I looked at the output of the samsung note 8 charger and its 2amps. Looking at an oem charger for your phone its 1000mah which is 1amp so half the charging amt thus the longer charging time. Now you need to take a look at the charger and read the output amperage on it and if its less then 2 amps you are fine. If its over 2 amps then I would discontinue using it as it could cause harm.
As long as the amperage of the other charger is less then the samsung note 8 charger you won't have any issues other then longer charging time. Once you go above the 2amp rating I would be concerned as you are putting more amps into the battery then what it could be rated for in the charging cycle.

Actually, the amps used to charge with is up to the device not the charger. If your device comes with a charger that has an output rating of [email protected] and you plug it into a charger rated at [email protected] it won't necessarily charge it any faster unless the device pulls more than it should. Just means the charger has a higher output rating and can handle more power hungry devices. It should not hurt the device. However, if you up the voltage than there will be problems so you need to make sure the charger does not exceed the voltage. Plugging the device into a charger with lower ratings will of course charge slower because the device cannot draw as much.

Thanks I checked the charger and it says 0.7amps.
Hi.
I have Samsung Galaxy Tab 3 10.1 and Galaxy S4 mini, and
I was wondering, can I cross use chargers of these two devices?
Both are 5.0Volt of course, but Mini's charger is 1.0Amp and Tab3's charger is 2.0Amp.
So, can I charge Mini with Tab3 charger?
I have understand, that if I charge Tab3 with Mini's charger, Amps are too low and charging is very slow.
But will Amps be too high to Mini if I charge with 2.0A charger? And what could happend to battery?
Thanks.

voltage is the only important bit ... 2amps will charge alot faster but MAYBE u will lose battery quickly ... but try
It's no problem

Hey.
I charged S4 mini with Tab 3 charger without any problems and quite fast as well,
but after my phone was fully charged I noticed that it drains battery very fast, even in idle.
If I charge S4 mini with original charger, battery will last much better.
It normally drains about <1% /hour or so (idle), but when charged full with tablet charger it
drains about 1%/5-10minutes (this was on regular use) or something like that. Much faster though.
So I think, I just use original chargers with my devices.
Another thing that I'm wondering is that my Tab 3 charges very slowly from time to time.
Sometimes it charges at normal speed and then the charger feels much warmer than time it charge slow.
I dont know if Galaxy Charging Current Lite (app) shows correct readings on my tab, but
normal charging (warm charger) readings are 1600-1800(amps?) and other times,
when charging slowly, readings are about 200-600(amps?)
I have tested with different USB cables, with same results. So is this normal (I think not), or is my charger broken?
i have lg pro 2 charger and it charge my tab s faster than the samsung charger
why is that?
check the V. My Note 2 charger charges slower because its 5.0 V, but the tab S is 5.3 V. Lg charger might be more.
Sent from my SM-G900F using XDA Premium 4 mobile app
yea you are wright so is it bad to use the lg charger?
lg v is 5 only can this damage the battary?
What you really need to compare is the current output (Amperage) output of the two. 5V or 5.3 will surely be OK. I think the Samsung wall wart is 2.1A your LG wall wart is most likely higher than that and this is really why it charges faster. It might not be good for the battery if it's too high. I don't know what the limit would be....
thank you pro
Your samsung charger is broke if the lg is Truely 2 times faster.
no not broke i tried 2 samsung charger and the same
lg charger was charging the lg pro 2 from 5% to 100% in one hour maximum
Please post the model number of LG charger.
lg travel adapter MCS-Q4UR
Bre careful i recomend u dont use another charger for ur device
How long take you charge from 0 to 100%?
Voltage is not responsible for charging time, but current. Samsung genuine charger has 2.1A current, but galaxy tab S gets only about 1770 mA (1,77A) maximum current (I measure this using voltage/current multimeter).
I have many chargers, and any of them (despite some of them have over 2A current) gets maximum current to galaxy tab S about 1.77A.
I also have I9300, and custom kernel (Boeffla, you can select own charging current from 0 to 1600mA), but i9300 takes maximum 920 mA (I don't know why they develop thi function to set current over 0.9A). Setting current over 920mA nothing changes.
I have to add, that very important is USB cable. Device can test the maximum current of charger, and when cable is not ok (for example cable is very thick) device can use a smaller than charger maximum current. You have to notice, that cable can works OK (transfer and/or charging) but can charge smaller than maximum current. Unfortunately on non-rooted devices you cannot see charging current (on device, of course you can use external multimeter)
I have many USB cables, and some of them on original samsung charger uses about 0.5A what is about 3x smaller current.
Hi Guys.
First off, I'm new here, and I did use the search function. However I did not find anything to my problem in particular.
I have a Lenovo Tab 2 A8-50 (it sucks, I know that by now).
I have 3 different original charger with the original cable that came with the devices.
1x Samsung Galaxy Note 5 - Adaptive Fast Charging - 5V, 2A.
1x iPad Air - 5.1V, 2,1A.
1x Lenovo Tab 2 charger that came with the device - 5V, 1.5A.
If I use any of those 2 other than my Lenovo charger, the charging process is incredibly slow.
For example, with the Lenovo 1.5A charger it takes about 90 min to charge from 25% to 100%.
If I use the Samsung or iPad charger, which have 2A , it takes 4-5 Hours!!
How is that possible that a 1.5A charger , charges faster than a 2A or 2.1A charger? Especially by so much?
I thought a higher Amp charger gives you shorter charging times?
Thanks
I have two fast charge power banks, one Anker PowerCore+ QC 2.0 and an iWalk Secretary. Neither will fast charge the Tab S4. Nor will plugging in the Tab S4 into the 3.0 and 2.0 quick charge ports on my Anker and Aukey multi port charging stations. The maximum charge (using AccuBattery app) I'm getting on these fast chargers is 500 ma and pretty up and down not really consistent. When I connect to a standard port it goes up to 900 ma without any dips. When I connect my Note 9 to the same fast chargers I'm getting 1300 ma.
Is this a Snapdragon issue?
Are you getting 800+ ma charging consistently with your power bank? If so which one are you using?

i never ever charge via fast charge as it destroy the battery in the long run, but i own an Belkin 15000 milliamp power bank.. i have just switched on fast charge for you I’m getting 1375ma charge that’s what AccuBattery is saying I’m averaging that of my power bank..
I hope that answers your question? pp.’s never i have heard of iwalk bit of advice avoid unknown brands! Anker is good but I don’t know about iwalk, get the Belkin one that I own.. I have charged my Note 9 twice in the last few weeks once full and once around 70% and I have charged my Tab S 8.4 LTE fully once and I still got 3 led lights left on the Belkin power bank..
Mate this Belkin power bank is a beast!
I will have to install accubattery but I have a Anker PowerCore 20000 with Qualcomm Quick Charge 3.0 and it works pretty well for what I need. but looking to upgrade to more power but smaller in size.
https://www.amazon.com/Anker-PowerC...re+20000+3.0&qid=1550676139&s=gateway&sr=8-13
These tabs support QC2.0 which allows for a theoretical 5V/2A or 9V/2A. In practice I've never seen it above 9v/1.7A. Does your accubattery app actually indicate the negotiated voltage? Or just the amperage?
The only way I've found to reliably check chargers, cables or devices is with a hardware ammeter like this:
Mini USB Tester DC Digital Voltmeter Ammeter LCD Display Current Voltage Meter Detector Power Bank Charger indicator Amperimetro
https://s.click.aliexpress.com/e/3rPyJb6
I've got one like this (reads 9volts despite the spec sheet stating otherwise):
