So I'm starting to remember how weird the charging of Note 10.1 is. I left it chargong for a couple hours and it barely charged, course it was on.
Do people "Power off" there notes before they charge it, or just plug it in and walk away?
Is there an app or some setting to auto "hibernate" or even shut off when it gets plugged in and not used? Just seems like an annoying habit to have to power it off regularly.
Note take a long long time to charge 5 - 7 hours for a full charge.
I always care mine while on, usually wifi and it charges from 20% to full in about 5 hours using AC. If you're charging via USB and it's powered on it will barely charge (its charging at 1/4 the current).
If you're using AC and it's still taking that long, you must have a battery hungry app running, try killing a) apps before you charge.

mine usually takes 5-6 hours to get fully recharged from 15-20%
I usually just leave on in the night. Wake up and it's fully charged.

any "speed charger" option? 6hr sounds ridiculous, particular if it's used heavily on the go ...
You're talking about 7000mah of raw power. So this takes some time to charge...this is just plain physics

You may be able to charge faster, I know there's a fix for the SGS3 but faster charging causes more heat which will kill your battery VERY quickly...
Unlike the SGS3 you can't just get a replacement battery and swap out easily... Slower charging will maximise your batteries life....
Yep, forget about charging quickly. The battery is high capacity so it should take maximum 5 hours. It may charge faster with a different adapter but that will shorten your battery life in the long run. If you want, you can buy a battery pack type portable charger I guess...

I find this tablets charging time so annoying I'm coming from a zoom with charged so fast compared to my note
Sent from my GT-I9300 using xda app-developers app
Not trying to sound mean, but what's the point to the thread? Is it a question asking how to improve charging times?
BTW, I have a Xoom and I think it's just that it charges a lot faster due to the special charging port.
It will charge much faster if you connect it to 220 volt power sources, rather than 110.
Well I wanted to point out that it is an annoying factor for people to think about when considering buying the tablet but I understand your point

Ummm... wall voltage won't affect it. The device only takes in 5v regardless of the where you plug the charger.

Is it just me or do you guys think its slow charging
Sent from my GT-I9300 using xda app-developers app
up to 90% it seems pretty decent. it's that last 10 that seems to take forever. I think the last time I charged it I went from 30 to 90 in 2hrs then the last 10 took another hour.
I ran my note into the ground today and then started a stop watch to see how long it would take to fully charge it. 4.5 hours!!!!
Mine takes way too long to charge also!!
Charging a battery faster leads to more heat which reduces the life of the battery. A very high capacity battery will take longer to charge, all else being equal.
They could have sped up charging by using a non-standard supply voltage/current from the charging cable (like ASUS Transformers, which uses 15v instead of 5v) and thus charging the battery faster. But it would have just got a bit hotter which is not good for the battery.
The battery stores many times more energy than a smartphone battery, yet it only takes about twice as long to charge. I think that's pretty decent.
Given the battery's capacity (7000+mah) and the charge rate (around 2A) I'd say the charge time is right around what I'd expect.
I found the charge a bit slow aswell, but the battery last so long that it balances things out for me, i was disapointed at first until i realised how well the battery performs, regardless what apps i used.
Yeah, Im not too worried about the 4.5hour charging time, my battery lasts me a few days and I can always plug it in before bed and wake up to a fully charged tablet.
I use my tablet during the day and before I go to bed I put it on charge and it's full in the morning. Do some people use their tablet so much in the morning it's out of juice by the afternoon? Give your fingers a rest. My battery lasts me usually all day. Even with looking at YouTube etc.

Slow charging after last firmware update
When I went to bed last night I had 19% power left. Like I normally do, connected my Note to charge overnight. Woke up 7 hours later to find that it had only charged up to 49%. Within 5 hours from a depleted battery, I usually have a full charge. Any thoughts as to why this is the case?
My galaxy note 2 charges faster than my note 10.1. But I have no problem with it.

I just bought my note yesterday, and I have to admit I was so surprised when I charged my note. It took 4hr to go from 7% to 89%. My previous Asus transformer tf300 can go from 0% to full charged in 2 hrs.( Not really big deal but it will be better if Samsung includes high voltage wall charger .

It sounds like you may have charged with your note 10.1 turned off.
The note 10.1 like many other tablets needs the tablet to be on while charging so the tablet can regular the rate of charge.
My Note 10.1 charges much faster turned on with WiFi, Sync and GPS disabled.
Mine goes from 25% to 100% in about 3.5 hrs.
from 90% to 100% takes about 45 minutes.

So do I (hello, fellow convert! ) and the real reason the Xoom charges faster isn't the port, it's 'cause the charger is 18W and is of a higher voltage (12v/1.5A vs. our 5v/2.1A). (I guess it could be argued that they had to go to a different port to not violate the PDMI spec the Samsung units use, though.)

You're being funny, I hope - our charger (just like any other charger released in the last decade) is a Universal Charger (100-240V/50-60Hz) so in any case the output voltage and current is the same no matter where in the world you plug it in.

That's not really true, though, as our tablet is in fact on when you're charging it- if you tap the power button when it's charging in the "off" state, you'll see that battery animation, and that's in fact a fully-running kernel but instead of running "Android" it's a special run mode more like a Recovery. The kernel is in fact running and alive.
FWIW my tablet charges far faster when off vs on, as there's far less simultaneous drain on the battery. Not sure what's going on with yours.
Back to normal

I hadn't completely shutdown my tablet since the update last week. I did so yesterday and now charging times seem to be back to normal. Something new from the update I noticed, when batery gets somewhere around 20% left, the battery indicator changes from green to yellow.
My tablet gets about 10 hours on battery, or more if im just reading the web. The most intensive app I run is candy crush and s-note.
That being said it seems to charge quickly, in about 3 hours. My complaint is the short charging cable it shipped with.

Is it safe to charge the battery overnight?
I mean, charging more than 100%, charging over the 3-4 hours needed, charging for 7-8 hours..
I think it won't effect it cuz i charge my phone from overnight too.nothing happens.
when battery gets full it stops charging after that
Of course
I've been doing that for a year.
Usually my battery reaches 10% at the end of the day, then I just leave it charging over night.
Thanks, i've been doing it since I bought the phone but I've never really cared until now..
Do you guys turn off the phone before charging overnight?
No. I don't know how does it affect the quality/capacity of battery though!
I remember as a kid I had those RC-cars and there were always warnings about how it will 'destroy' the battery if it is charged for too long. lol.
I don't have any battery problems.
Just make sure your LED isn't turned on!
I once forgot it on overnight...
It's a little dimmer now. :c
They said once it reachs 100% to stop charging. It can have an negative impact on your battery. Lithium technology or not. But I do it too. I think it just shorten the life span on a slow scale.

Here is the thing...
Yes the phone has a voltage shut off when it reached 100%.
However, it will start to drain battery immediately once it cuts off charging. Even when idle with teh screen off it uses some power. And once it drops to 99% it will start charging again until it reached 100%.
Depending on your set up and how much the phone runs when idle it would keep 'topping off' the battery several times overnight. This is harsh on the battery.
So it's not like once it cuts off charging it stays off until it's unplugged and replugged in. It'll keep charging everytime it drops to 99%

Ok guys often we unplug charger when fone says 100% but i found a simple trick. I installed battery saver app
https://play.google.com/store/apps/details?id=com.ijinshan.kbatterydoctor_en
Even after 100% the charging system enters trickle charging system which takes 10 mins even after 100%. Point to note is when the status is at 3 the fone reports the batt is 100% but that is the time trickle charging kicks in..and doing this my battery did showed little more improvement
Please note : I did not use any batt saving options via app i just used it for monitoring the trickle charge...
Really puzzles me why such a basic app would need to many permissions. Better apps on the store that requires much less permissions to run.

No need for any app to do this, I always let my devices to charge at least 10 mins more after reaching 100%.
No need for this application as phone does not give message of fully charged even after reaching 100% and status will be " (100% charging). Once the trickle charging is complete you will get message on lock screen" Fully charged".
80%
There is an option on my Samsung laptop to only charge to 80% to prolong battery lifespan. My Note 3's battery is so good, I would rather see such an app that would stop charging at 80% or 90%.
I usually have 50-60% battery left by the end of a long day. And that's with quite heavy work. I stopped plugging in the charger in the car for my commute, there is no need!

Wow! I agree that the note 3 battery life is the best I've experienced so far but mine is not as good as yours. Will have to try your method of charging to 80%.
When i forget my phone in the charger all night, i get like 20% more battery life out of it!

Just charge it overnight.
On the big screen U do not do anything ... For normal use the battery life is max 2 days. With gaming max 1 day maybe less...
I use the tablet a few hours a day (say, 6 hours) and among those most of the time (say 4 hours) it is on my desk so I can plugin the charger if I want.
My question is in this case what's the recommended behavior, for the purpose of saving battery cycles (I mean, say, after a year, the battery life per charge is reduced less compared with when it was new)? Would it be better to use the whole day without charging it, and charge at night? Or Charge it whenever I can?
Thanks for your advice!
Keep it plugged in. The battery will not overcharge and it wont effect the battert cycles as much as draining it and then charging it. Its better to do shallow charges (above 50%) than deep charges.

Trickle charge kills battery. If you arrive home late, put your phone on the charger and charge it overnight it kills battery.
It would be cool if it was possible that an app could cut off charging at ~80% when trickle charge kicks in. Maybe root is needed but is it possible at all?
Or a physical timer which cuts off charging after a certain time (2 hours to charge from 0% to 80; 1 additional hour to trickle charge from 80% to 100%).
Any thoughts or solutions for this?

There are timer sockets available for purchase. You set the amount of time you want to charge the phone and you're done.

Exactly that. Thanks.
Personally I use a powerpack to charge my phone overnight. Once the device is full, the powerpack stops charging.
Admittedly I have to remember to recharge the pack every week (it's 15600mah), but on the other hand I can also bring it with me. It's also safer.

If you're rooted, I know some custom kernels (I want to say I saw it in the Aroma installer of ElementalX for my Nexus 7) have an option to cut off charging around 95% for this reason.
But of course, that's only if you're comfortable rooting and tinkering with kernels and such.
