Quite honestly I have no freakin idea lol. Ever since swapping out my original phone that I rooted and keeping the new one stock I get absolutely ridiculous battery life lol.
Well I need to know from you guys, it's not that I don't know, but need to reconfirm. I think mine is taking much lower now than it was. A full charge, say from 5% to 100%, with Stock charger?
Thanks in adv.

roughly 1 percent for 1 minute. should be charged in a couple of hours

Charging from 0 to 90% happens in no more that 2 hours I would say. from 90% to 100% the charging rate gets slowed a lot. So basically shouldn't take more than 2:30 hours from 0 to 100%.
Thanks guys. Now I remember it was 2 hours 45 mins for me too at first.
Today it took 4 hrs 30 mins. Reason? I'll say tomorrow, after confirming.
Jeez PowerAMP!

I rarely charge it to 100%, usually to 70 or 80%. much better for the battery in the long term
Any research or refrence for this longevity ? I heard its always better to charge 100% ?

you are welcome. the general rule is to try to 1) avoid charging to 100%, really diminishing return the higher it goes; and 2) avoid deep discharge cycle. I usually use 40% of the capacity at work everyday, so charge to ~70% in the morning, use down to ~30% and then charge again. charging time in this range is rather linear, about 1 percent a minute

Yeah, it happened to mine too few days back. My Note2 went crazy, taking around 7-8 hrs to fully charge from 15%. So, i tried searching about the problem on google but to no avail. Did a factory reset with cache wipe and problem solved :good:. Now it takes about 2.5 hrs to fully charge from say 10% (using the samsung wall charger with phone switched on). I can only say that the slow charging was caused due to some software but don't know exactly which one? You may as well try the hard reset if anything else doesn't work out .
P.S : Btw i'm on stock fw with no root or mod! Only did some OTA updates couple of weeks ago.
Guys, we have a changeable battery and is already writed Inside to android that it won't charge to 100%, it just shows at 100% but really it is at 95%-98% that feature came with 2.2.1 update 2yrs ago.
And we can change the battery after 2yrs for 20-30$, unlike Nokia lumia users or HTC one x or iPhone users.

Yeah, thanks. But if you've Watchdog installed then you can see which app is going over threshold and keep running on background. And yes, this time, again, the culprit was PowerAMP! Uninstalled it and voila. The same app created problem for me when I had my S2, charging was pathetically slow, even I had to go to SC and they said battery is gone. But I didn't believe and asked a techy friend and he said it might be some app, and damn right he was.
Anyway, if anyone having the same issue like mine, that is, charging duration has increased with Stock charger, then install Watchdog (the lite version will do) and see who is the culprit.
I have no idea how a top app like PowerAMP could cause this! Jeez!

The same problem happen to me few days ago..during that that i was charging using extension cable where 3 pin plug is sharing with my note 2, laptop n tablet charging @ the same time..its take nearly 4 hour for fully charge the note 2 while im using n charging my laptop n tablet..but, from that i understand that when the connection all charging at the same time on the same 3 pin plug, the load are higher which decrease the current value (current drop)..that the reason why my note 2 charging slow..check if OP case is same like me??

So I decided to do what the manufacturer recommends when it comes to the battery, you know, charge it fully then discharge it. So I pulled it off the charger at 6am at 100%....moderate to heavy usage all day as I just unwrapped it, went to bed at 76%...so i turned on navigation and opened up a movie on Netflix hoping that would drive the battery down. I woke up at 56%! Myvold note would be dead, but this thing just keeps going! Christmas have mercy, this thing is amazing!

Yea man,Samsung did a phenomenal job this time around with the battery .I came from the i717 and I am so happy about battery life now!!!!
agreed. I was skeptical about the battery life reviews prior to purchasing and with a larger display and faster processor I figured no way any of this could be true. Coming from Galaxy SII that could not make a 6 hour day of use without being tethered to a PC and going out with anything less than a full charge was a recipe for disaster.
I can go a full day browsing and playing music on my Note II and not drain the battery.
Battery life is amazing. I have to really try and kill it to get it dead inside of a day.

It's not too hard to kill the battery on this monster. You can do a few things to really get the battery down, such as actual gaming, watching movies, and a lot of web browsing. Outside of that, it's really difficult to kill this battery under 24 hours. I have had very limited usage on my phone over the holiday. I am up to 77+ hours of battery time and a little over 3 hours of screen-on time and still have 7% battery left! If someone put a gun to my head and asked me to truthfully tell them when's the last time I had a phone other than the Note II, that could last 3 days without a charge, someone better call a really good clean-up crew!
I love the battery life, but I'm thinking about getting an extended battery just for the heck of it.

I have everything turned on. Bluetooth, exchange sync, all Google services sync, Skype in background, IM+ in background, weather update at 15min and still can't come close in draining the battery. I am also trying to fully charge the battery and drain it. It takes me a day and half to kill it with everything running and navigation running wherever I go.

When the phone uses L T E connection the battery goes down 10% per hour. I guess that is normal for everyone too.

I too am quite surprised by the battery life offered by the Note II. This thing simply smokes any other phone I've used in terms of how long I can get out of a single charge, it's really impressive. I'm used to plugging my phone in every 6-8 hours on a day of heavy usage even with power saving mode turned on, whereas the Note II seems to be able to go pretty much all day and even then some depending on the usage.
I have the s3, but two of my good friends both have noteII and the first thing they both mentioned to me about the phone is the battery life! After being around one for a full day with much usage, I must agree it is very impressive for such a big screen!
A friend of mine told me that his Note 2 GT N7100 is charging from 20% to loo % in only one hour.
the Battery usage is Normal as it withstand 10 hours with heavy usage.
He bought it a month ago.
Is this normal or he should go back to the reseller?
He is using original charger by the way.
thanks for your help.

Firstly install Galaxy Current widget and check the current that is getting transferred how much Volts, Make sure you try this with the Wall out let as well as USB from your pc and make a note of it and let XDA know here and we will suggest if there is any problem or not.
also mention if its complete Stock or Rooted and What Mods are implemented ?
Ok I'll do this first and let u know.
Thanks a lot.

i have to charge my note2 for 4 - 5 hours.
Is it normal? i want to charge faster. What should i do?ยด
Sent from my GT-N7100 using xda premium
Average normal charging time from 0 to 100percent is 2hours, regardless of the rom, from an AC wall charger. And about 4hours from a USB connected to the computer. 1hour is very unusual, I would suggest doing a full system wipe and reinstall the rom. If the charger is delivering above normal current then it may damage the battery in the long run.

Im getting lousier battery life these days. Used to be 10 percent for every half hour of screen time, now i do not get that. Is it time for a battery swap? Bought it since May, so its about half a year on now.
First try to stick to the charging cycle (which means, dont charge your phone untill it gets 20% or less, and dont take it off the charger untill it becomes 100% + try not using it while charging)
Second, my gn2 on the original battery, lasts 2 days, if im using it for heavy gaming.
Lasts 5 days for whatsapp.
And lasts 10 days with only some touches and screen on with cellular.
Maximum for my gn2 is 13 days.

I know right?
2+ days with moderate usage.
My estimate is like 16 hours from 100 to 0% (since I never let it discharge completely).... very annoying, since I can't charge it once a day. Screen usage like 1-3 hours. No heavy gaming, just the usual stuff, mail, facebook, news, foursquare, book reader, calls, IM+ chat....
My note 2 can last for about 12h with normal usage. That`s with 3-4h screen on time, and everything turned on(GPS,sync,data,auto-brightness)..Only thing that I noticed that eats the battery is gaming..For example Riptide gp 2 can take 10% of battery in 15-20 minutes...And yeah (CM 10.2,neak kernel)..
about 8hrs heavy use for me
My note 2 lasts about 8 hours too. This is basically cause I use whatsapp continuously.
