[Q] Samsung Tab chargers cause slow charging? Or is it crappy JB?

Is it just me? Is anyone else getting bad charge time from their pre-packaged Samsung charger? We use our Tab 2 10.1 and Note 10.1 (original) with the same Samsung charger. But, it has begun to charge slower and slower until we actually have to leave it overnight just to charge it. And even then it isn't even fully charged! This is a recurring issue with many people here and i haven't been able to find a solution. Maybe it's the rom... or its the charger.

Oy. I was hoping it was just the ROM. Samsung is known for crappy Touchwiz....but that's why i got the Note in the first place, LOL. So, an official manufactuer of this charger, like Belkin, would make a charger that actually lets this thing work properly? Sam Tabs...do they have a history of a really crappy charger?

You mean wall charging through DC or USB charging ?

Then there might be an issue with your Charging adapter.......it shouldn't take that much long..... Wall charging only takes 3-4 hours to fully charge the tablet for me...My tablet is almost similar to yours(4000 maH) and yours may be 4450 maH(if its tab 3 8.0),,,so you can consider 5-6 hours in worst case.

It is Tab 3, 7". I thought the same thing. I tried charging it with my Samsung Galaxy 3 phone - charging adapter but still the same.
I bought it in Dubai. I won't be able to go there until May. It has 1 year warranty. Thanks lokesh

my tab had been charging 100% within 5-6 hrs in wall mount... later i tried many kitkat roms and due to problem in bluetooth now i back to stock based rom... i tried 8 different roms in 5 days time.. and started to facing the delay in charging from the second day itself... many times even i work in my tab with charging... but still charge was draining rather than charging... even after switching to my old rom i am facing the same problem... the battery drains instead of charge...even when i keep it untouched it takes a lot more time to chrge, say for 10 hrs .... does that mean the adapter is messy or the rom related issue

Reviving the dead
Came across this thread looking for a solution to an extremely slow charging Tab 3 8.0. I also have an S5 as a personal phone and an S3 as a work phone. The Tab charged at about 2-3% per hour on all of the chargers. I plugged it up to my wife's Motorola Moto G charger and went from 65% to 100% charge in about an hour.
It's insane that the manufacturer of the device can't make a charger that works properly, but whatever.
If you're having this issue, try a different (respected) third party charger.

Finally, I guess I found the solution
Yup, It's not the device, not charger, and not the ports
Well, it's the cables,
Loose/Bad/Thin cables generally aren't able to transfer high rates of Amps, thus, a infinite time to charge.
I noticed my Tablet is having the same issue, so I plugged the original charger with it's original cable into my phone, and measured the current, my phone usually charges at 700ma, however, I noticed the current going up to 700ma for few moments, and then down to 400, again to 700, and down to 400, this made me think that this was a bad cable
And you ask, why Galaxy S3 and other chargers weren't able to charge the tablet quickly, it's simple, because these cables are cheaper cables that can't transfer 2A for the tablet, use a better 2A designed cable, it will charge your tablet

My tip, buy the shortest cable you can and charge with that. I have compared charging times with so many devices and come to the conclusion the shorter the cable the shorter the charging time. Everytime! A 20cm cable will dramatically reduce charging time!

Galaxy S6 slow charging issue

Hi,
couple of weeks ago, my phone starts charging slowly. Whenever I use any other charger, than original, its charges only with arround 400-700mAh - thats only 1/3 of the charging speed. The non original chargers have 2A output: Samsung car charger, ASUS tablet charger, ADATA powerbank. I tried different cables, restared the phone, charging while phone was off, cleaning the phone conector with contact spray.
The battery consumption is normal, arround 50mAh. The fast charging with original charger works OK. All the chargers, I mentoined, worked perfectly just month ago. Unfortunately, I do not have the options test the chargers on other phones, because all other are just slow chargers (1A)...
Any idea, why this is happening?

partialy solved
I perform some tasks, and it seems, that it helps:
I did: wipe system cache. This increases the charging speed from 1/4 to 3/4 (400mAh -> 1300mAh) from the powerbank. The charging speed from car charger didnt changes
Then I did factory reset of the phone and it seems, that this helps.
The charging speed is very depending on the proper usb cable used. One cable works fino on one charger, but performs bad on another...

all USB Cables have different amperes, some have 2A some have 2.1A, furthermore, it also depends on the power source, the car's charger couldn't be as strong as the wall socket i think.
Anyways, on a side note, i suggest you try Aukey quick charge 2.0 powerbank. fast charges your S6.

I am wondering if this may be related to an update? Both me and the wife started experiencing this same problem, at the same time (different chargers). A few nights ago our chargers were working fine then the next night after 12 hours of charging battery is only around 80%
I did a factory reset on mine on Sunday for other reasons but this has made no difference to the charging issue

Download Advanced Battery Calibrator from Play Store.

I tried this app as you suggest and to be honest my battery is worse rather than better. From fully charged, my battery has dropped by 20% in less than 2 hours pretty much being on standby. See screenshots below.

It's weird, anyway download the latest stock firmware for your device model and flash it using Odin. Wipe everything from Recovery Mode before and after flashing.

What difference would flashing stock firmware make? My phone is up to date and I did a factory reset on Sunday

Hi everyone .I'm also using s6 is very slow almost a week and it take almost 5 hour to be full charged and also it's not detected bu usb in computer and otg is also not recognized

I have the same situation, my s6is chargind just at 400mA speed, and my pc is showing USB not recognized (windows 10), thought it could be a usb charging board just pluged in new one, nothing changed... the same problem. there is somthing more, likely usb chip on motherboard or maybe battery... or some kind of problems

my culprit was the provided samsung cable. if you're in the UK the "betron" reinforced cables from Amazon sorted my problem... cheap and comes with warranty. Mine is still going strong and no problems here

For my case, it happened after my phone is updated. I brought my phone to a service center unfortunately it's already out of warranty. They are asking around $90 to have my phone fixed. According to them, they need to replace the battery and the sub board.
Im really dumbfounded how this happened.

I have the same problem with my s6 I have replaced the charger port and still won't connect to the pc or fast charge

Slow charging after update

My phone is taking forever to charge since yesterday, and the only thing that changed was I updated to COI5. Was never rooted. My phone has been on the charger for 4 hours and is 63%. I've tried different chargers and power bricks, all which worked fine yesterday. I would get a full charge in under 2 hours. My current time to full from 63% is 2 hours 13 minutes.
Anyone else noticing this after update?

Same happening for me, actually. I noticed after last week's T-Mobile update that my phone doesn't really fast charge.

Are you talking about the 30mb update?

Yes, I have.
When you plug it in, make sure it say fast charging. I noticed that it sometimes shows cable charging, I then replug it until it say fast charging.
roger1955

I'll have to try that Roger, as I've noticed the same thing. Really slow to charge now, so perhaps I needed to reseat the cable. On a positive note, I tried Samsung Pay at PetSmart today, and have to admit, I was very, very impressed.

After the update i noticed i have to plug ,unplug , replug for fast charging to work as well

I heard the same problem. it was an app that i installed which was causing that problem. problem solved after installing all my apps.

I'm having this same problem and it's driving me nuts...

From my troubleshooting I found it to be the Samsung charger. Every Samsung micro USB cable including the one that came with the phone. If I use any other micro USB it charges fast. Any Qualcomm fast charge brick works better than the Samsung brick as well. All the combinations I tried that is what I found. Use a moto quick charge brick and any micro USB cable. It seems that whatever update was sent out only let's us charge through USB 1.0 amp and after 3 or more tries fast charge with the Samsung cable and adapter. Not sure how or why that was done, but every other cable charges 2.0 amp and fast charge on first try

Weird my note 5 fast charging started acting up as well. Also my phone somehow went into factory mode while it was off all I did was plugged in the charger too. Been having a lot of issues with the Note 5, exchanged once already now my new phone is having the same issues still.

Im also having issues with fast charging. this is really pissing me off....

My wife has the same phone and with my charged and cable if the fast charge works, please your help I do not know what to do

Do you use the good charger?
Till now, I used a Samsung charger with same output (ampere and volt) and it worked fine. But since 2 days, I had the same issue than you. I didn't use this one of Huawei because the plug wasn't compatible with my country. I then tinkered the connection to adapt it to my country. Now all works fine again.

Hi, I have been facing the same problem recently. Please tell me if you found any solution to the problem? I have done everything to solve it. Changed chargers, done the hard reset. Even replaced the spare part. But my Mate 8 still does not connect to PC nor does it support fast charging. Any help will be appreciated.

malfunction of the battery

Hello everyone! this morning something really unexpected happened to me. my Honor 8, which I usually leave on at night, woke up with me about 20% of residual charge. after a few minutes of use, the latter has passed (20 ---> 2) in an instantaneous way, forcing me to turn off the phone. then I connected the charger but charging still started by 20%. Unsatisfied, I turned on the phone again and again I went from 19 to> 1% instantly. now I'm charging with the charger but I have no idea what might have happened. I think the life of the battery is good, since alternatives are generally fast charging with slow charge from the USB port of the PC. what could have happened?

Do you use the stock charger that comes in the box? Other chargers don't work well with Honor 8

Yes, only stock charger! Sometimes USB port of the PC (like 1 charge every 10 from original charger)

Check the charger for any possible damage. There may also be something with the phone itself.
