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.

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.

Sent from my Nexus S 4G using XDA App
I donno...between 3 and 3.5 hours roughly. Pretty fast.
I'm using stock charger that came with phone.
No light indicator to indicate charging or fully charged? I've been charging via USB and it gets to 94%, so fully charged and stops charging. That's as high as it will get...
About to go work out, going to put it on wall charger and see what happens!!
Anyone else have this problem or just me because of the usb charge?
Mine only goes upto 94% br well with the wall charger.
Apparently It's a safety feature
Sent from my Nexus S using XDA App
Mine goes to 96% typically and I've once seen it reach 97%, it's a bug, not a safety feature. As a safety feature, to prevent it from overcharging, it's supposed to charge up to 100% then stop charging until it reaches a safety level such as 95% then resume charging again. This is just a bug in the system.
Takes me just over 3 1/2 hours from dead to fully charged.
Mine goes up to 98%. Once in a while it will go up to 99%.
Sent from my Nexus S using Tapatalk
1500mAh/700mA = 2.1h, i.e. less than 2h.
It will never (ever) reach 100% if your charger and phone is working correctly. It IS a safety feature. Eventhough the phone is connected to the charger, it still uses battery to run. The charger stops charging when it gets close to 100% and charges some more when it's safe to do so. Meanwhile the phone uses the battery to stay alive and if you unplug it between theese charging cycles it will be anything between ~93 and ~99%.
It seems like forever honestly with this phone. My Evo would charge in about an hour and a half. This phone takes easily 3.5 hours if not more.
For some reason Samsung chargers take longer to charge a phone.
If I use my HTC charger the phone charges a lot quicker

HTC chargers are typically 1000mah and samsung chargers are 700mah... So there's the difference.
what is up with this phone i went to sprint got a new battery not knowing this was an issue of not getting to 100%. i came from att and having the htc inspire kinda like the evo i guess it would fully charge in about an hour and last me about 12 hrs of actual use. the nexus s takes about 3 hours to fully charge and i get about 5 hours with 0% brightness im thinking about going back and returning the phone.

While I do not what is draining your battery so quickly, the reason for the charge time is stated in the post above yours. The charger that came with the Nexus S is a 700mAh charger, while many others (notably HTC's) use the full 1000mAh charge possible on a MicroUSB line. More power over the same amount of time = faster charging.

hi there
is any one have my problem?
i buy a nexus s in yesterday
but the battry cant hold charge for atleast 1 day!!
it usage is about 1 - 2 % charge in every houre!
i do workinig for example 10 minutes with the phone for setting ant etc .and then i saw the 4-6 % of battry charge go down!
or sometimes the phone is puting on standby for 30-40 mintunes
with no sms or calls,but its use about 6 % of battry chage!!!!!
and for wifi and games its even faster that it!
finally for a normal usage like 10-20 sms ,15 min call ,30 min browsing phone menues and apps and 20 web,
its going to be full empty!
and its meaning it cant keep charging for atleast 1 day!
i have the SLCD one ofcourse! => I9023 XXKD1
i couldnt find any superamoled version in my country to buy,
do you think its for the slcd screen?
i didnt think that its may cause this charging resaults for me just for the screen type!!!
my charging time is about 1.5 - 2 houres to full charge,that its not acceptable for me too!
i had a diamond2 with that poor battry.but i didnt think so the NS could be the same and even worst!
i upgrated my device to gingerbread officaly, from 2.3.3 to 2.3.4 by the phone,but its still no differance!
it the back of the battry i can see the 1500MA Lion , but the battry control app i my NS shows maximun 1200 MA power!?!!
can it be the truth?
do u think its battry power completly depended to rom and radio version to fix?
if that is,can any one intreduce me a good and fast and bugless rom and radio version?
thanks a lot :roze
I am running Continuum v5.6. I have gotten amazing battery life but I do not understand what I do to obtain this. Here is what I did.
So I was getting terrible battery life and decided to recalibrate my battery. After wiping the battery stats after making sure my phone was %100 charged I decided to run the battery till my phone shut itself off. I was getting terrible battery life even after the wipe and everything. In about 24 hours the phone drained itself out with moderate to light use.
I recharged the phone with another USB outlet forcing the phone to charge slowly in USB mode. I believe it charges at 400 mah instead of the usual 700 mah when using the samsung charger. I left it until it charged from 2% all the way to %100.
This was mid Saturday. It is now Monday morning and I am still running on the same charge.
I don't doubt I could have reached up to 48 hours on my Captivate! I've never even came close to 36.5 hours without needing to charge.
What do you guys think gave me such great battery life? I am speculating that when we recalibrate our batteries we should do a SLOW charge. Slow charging batteries have always been the best method in the past IMO.
Possibility. However there are MANY different factors that contribute to battery life.
I would like to see some other confirmed reports of USB charging leading to longer battery life over AC charging.
Interesting stuff though.
Slow charging is always better with batteries. But in over a year i have never used usb to charge. So cant say if it last longer or not. I am a heavy user so no time for a slow charge
seems interesting...ima try this out as soon as i find a charger that charges at a slower speed..
I agree
I am 100% confident slow charging lasts considerably longer.
I normally use the USB on my computer to charge, and I get two days of what I consider pretty heavy use out of it, maybe longer but I'm never away from power for more than 2 days. When I charge with AC it's pretty tough to even last a single day.
Other things help as well. I always have the screen at minimum brightness, I would turn it down further at night if I could. I don't run any home screen widgets that constantly update, no haptic feedback, ect.
I'll have to try this out!
Let me do all the noobs out there a favor and ask how do i slow charge? Where do i get the whatever i need, is it a cable or plug thing and is the stock samsung stuff fast charge i assume?

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.

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...

As everyone else has mentioned. Charge it at night.
Just curious how you handle this, because everybody says something different:
First use: completely charge the battery and then complete discharge, or first complete discharge and the full charge?
I also remember someone telling me that you shouldn't let your battery run completely empty, is that true?

I don't buy the bit about wireless charging. I've used my Nexus 4 with an LG wireless charger daily for almost a year now and haven't noticed any side effects with battery drain or overheating. In fact, I'd argue that the Nexus 4 and my Nexus 7 get hotter when plugged in than they do on the wireless charger. I have absolutely no reservations about using the Nexus 5 on my LG wireless charger when it arrives this week.

Well the charge and discharge isn't necessary, IIRC that's only for older battery technologies like Ni-Cd batteries (Nickel-Cadmium). On the other side, you probably shouldn't let it discharge all the way since these are Li-Po and it could shorten their lifespan (apparently).
I just plug mine in whenever I'm near a charger.
I'm at work at my desk... its plugged into the charger.
I'm in my car... its plugged into the charger.
I'm at my girls house... its plugged into the charger.
I'm at home replying to xda / android central posts... its plugged into the charger.
This is what I've done with every phone I've had. I only had issues with one battery. I used to have sprint and I had the Samsung Galaxy S2 Epic 4g Touch. After about 8 months the battery got fat (they said it was called a swollen battery at the sprint store) and it kept turning off. They gave me a new battery at the sprint store and I continued with my routine above and never had any other issues with it or any other phones.

this is right on both accounts. you dont need to discharge it all the way, and doing so will reduce its life a little. i recently read about lithium poly batteries and the particular blog i was reading talked about running the battery down to 20% then charging it to 80%
i think when i first get the device i will use it down to 0%, charge it up to 100% uninterrupted and then hopefully keep it within that 20/80 range and probably doing a 0-100 refresh on the first of every month
If you guys want to read some in depth material on charging lithium batteries I would recommend reading this. Very informative.

It's fine. Phone manufacturers know that people charge their phones overnight. That's why there is a trickle charge mechanism built into all phones nowadays.
u have to calibrate the battery too
Over the last month I've had somewhat of a binge of buying phones from Amazon and returning them for one reason or another and I've noticed that the first 1-3 days of phone ownership are usually the toughest on the phone / battery.
I've owned over the last 2 months (in order):
- S4
- HTC One (x3 as 2 were faulty out the box)
- LG G2
- S4
- N5
I've decided on the N5 as being the best for a number of reasons, but my favourite is price.
I havn't worked out whether it's a combination of new phone = more usage or new phone = requires battery calibration. But the N5 is the only device out the major players that actually made it through day 2 (the day after it came out the box) without a charge midway, infact it's ONLY JUST gone on the charger after some 28 hours of moderate (3 1/2 hours screen on) usage.
My gut feeling is that once you're out the first week just use the damn thing, but the first few charges can make a difference to how quickly the battery feels calibrated. My N5 came with 50% charge out the box, I ran it down to 0% and topped up charge as much as I could the first day. Once I got home I once more let it 0% and then did a full 0-100% recharge. Then my 28 hour experiment started and now I'll just use it as normal, and not worry.
I keep brightness at 50% to enjoy this beauty and I do not give a single **** about the battery.
Charge battery between 20% - 80%
Do not use phone while charging
Unplug charger when battery full
Hey guys,
You can see the problem in the Screenshot. At one point the phone stops charging fast and goes on charging very slow. It looks like the phone thinks the battery is full and minimizes the charging power. It is a 1500mah battery, bought a few days ago. I also calibrated the battery at 100% in the 4ext recovery. CM 10.2 from 08.08.
Sent from my Nexus 4 using xda app-developers app
Provably not a problem at all. My guess would be that the battery or charging circuits were getting too hot so it dropped the charging current - fairly normal behavior.
The phone is staying completely cool. I think the calibration is wrong. It is supposed to charge slower at 90% Not something like 50
Sent from my Nexus 4 using xda app-developers app
I suspect a cheap battery... What brand is it?
Its a german brand MTec, oder via ebay.
I've noticed my battery does the exact same thing. Charges quickly to around 50% and then very slow for the remaining 50%. I'm using the original HTC battery that came with my Desire S so I just presumed that it was either the due to the battery aging or perhaps due to the CM 10.1 I'm running. Can't say I noticed this charging behaviour before I used CM 10.1 but I didn't immediately notice it after flashing either.
My phone takes around 8 hours to do a full charge. I've noticed that I can get it to charge to 100% more quickly if I let it charge to near 50%, unplug it and leave it for 5/10 mins, then plug it in again. It's starts off with a fast charge again. It slows after a while but overall it's a quicker way to get to 100%. It's probably not the best thing for your battery to do that regularly so I don't do it unless I need it to charge quickly.
