I just (10 min ago) went to check the time on my phone, and when I grabbed it, it was extremely hot. When I turned it over (I put it face down at night so the notification led doesn't bug me) it was showing the battery charging screen except it was a question mark. The phone was plugged in since 10 pm (its 5 am now) and when it had cooled down enough I turned it back on and it said I only had 50%, even though it had been charging all night. Has anyone else had similar overheating issues, and should I return it for a new phone?

Tried a hard reset? If ao, return the phone is what I would do. No way its supposed to drain that quick or heat up. Charging, navigating and playing music over BT and my phone is warm, not hot.
Had a similar issue about 3 weeks ago. Wasn't plugged in charging though. It was just sitting in my pocket. I thought it felt warm against my leg so I pulled it out and the phone was super hot! Turned the phone off immediately, let it cool down, and it hasn't done it since.

The other day I was charging (stock moto AC charger) my battery (40%) and downloading stuff via 4g and mine got to 46 degrees C. I slid open the keyboard and put it in a opening of a vent that was blowing 60 degree F air. 1 hr latter battery was 80% +/- and i dl'd more stuff.

You said there was a battery with a question mark. Was your phone booted up at this point, or were you in the 'battery charging mode'?
Sounds like the phone overheated, which can sometimes happen. You could try to get a replacement, but unless it happens consistently they might give you trouble trying to return it.
The annoying thing is, they say our batteries aren't supposed to be removed. It was nice being able to swap in a spare when my wife was done with her A855 moto Droid and same with having a "spare" incredible...
Anyone know the reason they made ours not come out?

It is my understanding that they used a special type of battery to get it so thin. The downside to this special type of battery is that they are easily bendable, but explode when bent
As a result, they don't want anybody touching the battery and exploding themselves.
Somebody who is more knowledgeable in battery tech could probably give a better explanation.
Couple weeks ago I was using the GPS and had the phone on the Motorola cardock while plugged in (with a Verizon charger) to the car. Took the phone off to make a call and I literally couldn't touch it. I kept it on the side and opened the battery doctor app, told me the battery was 58C. Immediately pulled aside and turned off my phone. Stupid phone has the locked battery door also so I couldn't pull it off to let the battery cool faster. Worst battery door design by Motorola.

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.

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.

My battery got drained to about 4% this afternoon and when I got home I started charging my phone but now it doesn't boot anymore, connected to AC or no. It doesn't even show it's charging.
This is a new battery, not even 6 mo old. Anything I can do?
keep it connected to the charger in off condition for a couple of hours and try again... if still no go then try a working battery from another note
It's been connected to the charger for at least 8 hours now... Still it doesn't charge and it doesn't boot.
Is it a stock battery or a cheapo one?

It wasn't cheap and by the looks of it it's an original one, not the one that came with the phone, but identical in all respects.
This helped, now the phone is charging.
Got my Note 5 with the adaptive faster charger about 3 and a half weeks ago. On my second Note 5 now (had to send the first one in due to problems) and everything was working fine until a couple of days ago. I would notice my phone saying "charging" and then I would have to unplug and plug it back in then the "fast charging" would appear. Now it doesn't ever go into "fast charging" and no matter what I do I always get "charging". I currently have 93% battery and it is telling me 15 minutes until full which seems a lot slower. I tried using my old Note 4 fast charger and get the same issue.
Anyone else with this issue? Wondering if it's the phone or actual charger and if there is anything I can do to get a replacement.
I never paid attention, but I just always figured that the adaptive charger would switch from 5V/2A to 9V/1.67A when it was nearing full charge.

Try a factory reset. If it doesn't work, get it exchanged asap.
Check if the fast charging option in power settings is enabled

I know this thread is kind of old but in case you havent resolved your issue. I had the same problem with my phone so I called warranty, they sent me a brand new charger with cable and it works fine now. I compared the one they sent as a replacement and the one that came with the phone and the replacement cable is actually a lot thicker and feels way more durable. My guess is Samsung cheaped out and threw in a crappy cable to save cost but it wears down A LOT faster than a durable heavy duty one like the replacement I got. Anyways the new charger is working 100% of the time and has held up for about a week so far. we'll see how much longer this cable last.

I actually called ATT customer service/warranty center. He told me he'd send me a new charger and cable and I needed to send back my old one. Got it in less than 2 days. Sorry for not being more specific. Also fast charging is still going 100% of the time on the new cable.

Thanks. Looks like I'll have to give my provider a call. I can verify that once I switched the cable I have no issues fast charging. I'm not having a good experience with Samsung so far. When you charge almost $1,000 for a product I expect it to be free of defects in every day use. Meanwhile my cable is messed up after only 3 weeks of owning it and the phone has signal problems that require me to cycle airplane mode to get data working. Never had a problem with my Nexus phones or iPhones. Really poor qualify control.
I recently purchased a Note 8 but I notice that the phone only charge up to 80%.
When the battery is charged up to 80%, the red/orange led notification indicating the charging process turned off. I had to unplug and replug the charger multiple times but the battery only jumped up to 83~85%. Is this normal or is the battery defective?
Everytime, I unplugged and replugged the charger. The charging symbol & led notification showed up for about 30~35 sec and then it stopped charging.
Does anyone have the same problem like this?

Check the bootloader screen. Usually this restriction is placed when the phone has been rooted. Maybe your phone was a customer exchange, which if that were the case I would be very pissed off.
Either way, if you haven't interfered with it in any way then it warrants a replacement.

Have you tried re-calibrating the battery?
Maybe try draining the battery till it dies, then turn on phone until it dies again.
Finally charge it to full whilst switched off (i.e. notification light turns green)
This used to happen to me sometimes with an extended battery on the Note 4, where the fix was to remove the battery and replace it (obviously not possible here)
Sounds rooted to me. That's the only thing I have seen here at XDA that causes 80% battery . I would send it back right away, don't even try to screw with it. Samsung sent you somebody else's problem.

Read my reply again! I said maybe he was sent a customer exchange. It happened to me once (not direct from Samsung but from a very well known and normally reputable online store.
I sent my phone back to Samsung service center to fix the charging problem. They replaced some components on the mainboard that cause this problem. However, when I received the phone, I performed some tests to check if the problem still persists.
After I received the phone back, my phone was able to charge itself up to 96-97% and then it stopped charging. I had to unplug and replug the wired charger to get my phone up to 100%. So I don't know this is because of the software/firmware from phone or not !!
Then, I used the phone for a couple days and when the phone was about at 25% battery, the battery drained so fast. In about 10-15 min after 25%, the phone turned off.
I let the phone off and charged the phone again, but again, the phone could not be fully charged. It stopped at 96% again!!! Does anyone have the same problem?

I have the same problem.
some of this is caused by samsung's rightful fear that their batteries will explode. there are many complaints online about how slowly the note 8 charges. mine does some weird stuff while charging sometimes, and i am chocking it up to restrictions sammy has put in place to prevent another disaster. sometimes mine will only charge to like 87%, but if i unplug/plug in again it will finish charging. i think it also tries to charge around your charging/usage patterns as well. i suspect there is a way to turn off this feature.
I am getting the same issue. I have had my phone for for over a year now with no issues. And just a couple weeks ago I started having these issues. And no, I have not Rooted my phone, for all the people who suggested rooted.
Was there ever a fix for this?
