I calibrated my note 8. After charing my note to 100% and used it the next day, then it reach 93%.. then i connect it to a laptop using my original usb cable. then after transfering my files i noticed that my battery reach 100% again even if i only connected it for about 5mins, is it normal? is it the effect of battery calibration? thanks for your answers

Hello all,
I am facing a weird issue and will be grateful if some solution is available for the same.
What Happened:
1) I had connected to a PC via a USB cable for data transfer.
Observations:
1) The cellphone had shut down unexpectedly
2) Battery was overheated
Steps taken after the issue:
1) Removed the batter for 5 minutes
2) Inserted the battery
3) Cellphone started working once again
Issues after all the dilemma:
1) Battery had drained out at the end of the day
2) Connected AC charger, and the cellphone showed 100% charged immediately as soon as it was connected.
3) Same thing happened when connected with USB
4) Still kept it connected to the charger overnight. The phone was charged, completely.Happily used it for the full day but at the end of the day again the battery was drained out again. During this the indicator did not refresh at all. The batter indicator was full during discharge fo the battery
5) And now the phone cannot connect to the USB for charging or data transfer as well.
I will appreciate any help for this issue
Thanks in advance!
i face some problem. Just take your phone to service center. Now my phone don't act like this
I think you need to re-calibrate you battery. Try Zep* battery calibrator or download one from the market, or you can do it manually, just search xda on battery calibration.

my battery acting funny too lately, do you play games, how much your battery consumption on 3D games ? I get 10-20% down on 10 Minute's of gaming... the most battery consumptive device I ever use, must be something wrong with the battery...
When I connected my Tab Pro 8.4 to my laptop just now, the battery status jumped from 93% to 100%. My workaround solution is to charge the tablet with the USB wall charger and wait for it to indicate a full battery to know that it is truly at 100%. I will get a notification to unplug once it's fully charged. From there, I think that the battery status is accurate...until I connect the tablet to my laptop again.
Why does this only happen when I connect the tablet to my laptop? This doesn't happen every single time, but enough times to cause annoyance. Is there a better fix to this? Thanks...
My 12.2 Tab Pro loses about 10% charge for every hour in use: about right, I think. It takes about an hour to charge about 10% when not in use: rather slow in my opinion.
When I am using my Tab while connected to the mains, it will not charge. In fact, it loses about the same amount as when it is not being charged.
Using in this context is reading books (Kindle), reading newspapers (PresReader) and web browsing.
I have tried USB 3 and USB 2 plugged into a mains plug, and USB 2 directly connected to a mains plug. I have tried different cables and plugs. They all behave similarly.
Should it not charge when in use?
Are you using the Samsung charger and cable that came with your tablet?

Amongst others, yes.
I have same problem with mine. Battery can die super quick from 100%, then a restart shows it with 60% (as example) battery. Are you rooted? I've seen others with similar problems, but no answers. Thinking of sending back to get fixed

Are you charging it from the computer?
Mine doesn't take an hour to charge 10%. You probably have a defective unit.
If it takes an hour to charge 10% using the stock cable and charger, there's a hardware fault somewhere, be it your cable, charger or the tablet itself.

USB ports do not provide enough current to charge these devices. I understand that, when on, the power drain exceeds input from USB sources. I use AC with adapters rated at 2 A. I also have a car charger with that current rating that plugs into the car lighter. USB ports, whether in computers, cars, or airport lobbies are useless.
If you are using wall plug rated at 2A and are not charging, then one of the 3 components is bad (charger, cable, or phone).

I'm also having the same issue . I have left it plugged in ( wall outlet ) and off for an entire day and it still wasn't charged 100% . I am rooted .
slow charging

I bought my Tab pro 8.4 in June 2014. I use it about an hour each day and charge it when the charge drops below 30 percent.
Recently I have noticed, it takes all night to charge. This should not happen. my Ipod touch charges in less than 1 hour and its an old version 3, (6 years old or more)..
I am using the wall plug that came with the unit, to charge it. It should not be taking 12 hours.
This seems to be a problem with these 8.4's.
there are a number of possible causes: bad battery, port, charger, power source, too many apps .... you might want to read this guide on how to fix an Android phone that doesn’t charge (or discharges) when connected to a power source to help you identify the cause and fix it

I have the exact same issue with My Galaxy Note Pro. It will not charge while in use and the battery drains extremely fast even with most all settings turned off and screen brightness turned down. I turn the tablet off every night to charge and the charging speed is extremely slow. I am using all Samsung OEM cables and chargers. Ive tried USB 2 & 3 cables with no noticeable difference. I am going to do a factory wipe and then closely monitor the power useage. Im starting to think that there is an issue with the Note Pro based on the sheer amount of users reporting the same or similar problems.
If anyone has figured out the culprit behind this issue, please pass it along!
Battery indication issues
I have the same problem with charging the Note Pro 8.4.
After some investigation and multiple tries it seems very much that the reported battery level is not in line with "reality".
It happened numerous times that while the tablet was on and charging, the battery level did not go up or only 1% every hour or so. After reboot the reported battery level was much higher.
I decided to throw some apps from the tablet which vastly improved the battery level indication and more or less seem to work as expected. I know from previous experiences with my Note 2 that some apps/widgets can wreak havoc on very basic functionality like charging. For example the stock picture frame widget on the old Note 2 had the effect the charging icon did not update. After reboot of the phone it was much better. Removing the widget solved the problem.
All in all carefully check installed apps/widgets on the Note Pro (8.4) because the firmware does not seem to cope well with certain apps/widget combination whatever that may be...
hi there.
i bought a brand new Galaxy Tab S 10.5, ive been charging it overnight. on the screen i always see that it is at 100%(while the device is off).
as soon as i unplug the charger and turn the device on, battery drops down to 99%.
however, as soon as i reconnect the charger while the device is on, it then charges to 100% and stays on 100% for a bit after some use.
just wondering if others have the same issue? or if its normal for it to not charge/stay on 100%?
and also how quick do others devices drop down from fully charged to 98 or 97%? because mine seems to last just a few minutes between the full charge-97%, when its updating apps and receiving notifications once I turn it on.
the battery will not be charged if it reachs 100% . btw it is normal , you dont have to be worry

ok, but how quick is it meant to drop down from fully charged to 98 or 97%
there isn't much running in the background. checked it using task manager and i only have basic apps running on the tab.
especially when its updating apps or on initial start up....it drops down within a few minutes.
I also face this kind of problem right after I bought this Tab, but 8.4 version, it will stuck at charging 100% for a long time but from 15 to 100 only takes 2 hour. Plus ,the battery drain a lot.Drop 1% in a minute.. But after a few cycle it gets better and dont have this kind of problem anymore.

ok cool. well i'll try a few charging cycles then.
also, when i connect it to the Desktop PC with the USB cord, it shows on the tablet that it isn't charging, it has an ex on the battery icon.....but in actual fact, the battery percentage does go up??? how or why??

The X on your battery icon, when connected to PC means that you do not have enough power from a USB port to charge the device. The tab recognizes that it is connected to a USB source but the USB port is not outputting enough voltage to charge your tablet. This is normal. These tablets are not meant to be charged from a computer. Nothing to worry about

But very slowly right?

I have the tab on sitting on my desk connected to PC. It charges, but if you use it at the same time charging can hardly keep up.
If I remember correctly it charges around 5 % an hour when connected to my PC.
