I went to sleep last night with the battery at 15%, slept for ~5 hours, woke up, and the battery was only at 50%. Is this normal? Does it take this long to charge for anyone else?
For reference I'm using an HTC charger from a previous Android phone, would using the Samsung charger make a difference?
Yes it seems like too long for too little of a charge. Give the Samsung one a shot.
Your using a charger that at very best pumps out 1amp
The default note 2 charger pumps out 2amps
In other words your charger will take twice as long as it should to charge your phone

If you use note 2 charger,than it can charge to full within 2 1/2 hours.

I agree, the Samsung charger with its 2A is necessary for this large battery if you want it to charge fast.

It's there any harm done to the battery if you use an old charger from a previous Android?

were you charging from mains or pc ? from pc it takes .... ages to charge ( like 1% in 15~30 mins) but from mains it takes more or less 2-2.5 hours to hit 100%.

It's from a HTC wall charger. I changed it to the Samsung charger that came with the phone. Will let you guys know how it goes when I go to sleep tonight.
Will the USB cable make a difference? I have a super long USB cable that I like to use instead of the short default cable that came with the phone.
I know about the 1 Amp / 2 Amp charger ratings, but unlike the original post:
I have my Motorola Xoom 10.1 plugged into the wall, and i use a USB OTG cable from the Xoom to charge my Note 2 overnight (so to only use 1 plug socket).
So i assume this is providing 1 Amp or even less to my Note 2.
I often have it charge my Note 2 from 5% or less all the way to 100% in under the 6/7 hours sleep i get.
Somehow the original posters 35% charge in 5 Hours seems very slow.
with my Samsung box set usb cable, it still takes 8 hrs to charge 100%. sometimes the red led is on but without a single percent charge. I am talking about charging with the usb connected to the laptop. if plugged in power, it takes less that 3 hrs for a full charge.
I remember my previous win7 was perfect, may be the new win8 is having some problem or not, I don't know?

My Xoom must give out some good Amperage if i can get a 100% charge in 6/7 hours then.
The "only" thing that matters is the voltage.
The included charger puts out 5V(+-5%) and 2A.
Too little voltage, and it won't charge.
Too much voltage and you will burn a fuse or the charging circuits in either the phone or the charger.
The phone chargers (no matter what brand it is) are within the limits, so don't worry.
The current (Ampere) shows how much power your charger can deliver at a given time, but the phone itself decides how much current it can take.
A standard USB-port (1.1) gives out 5V and 500mA.
I've built LED cables based on this.
USB 2.0 and higher are supposed to be able to give up to 1500mA under certain circumstances.
My motherboard has a pair of special USB-ports which can recognize cameras, phones, etc. and charge with a higher current and even without having the computer turned on.
While charging through USB-ports a full charge takes ages for me, 6 hours while sleeping will never even charge close to 100%.
On the other hand, charging though the adaptor that came with it or any other adaptor that can pump some juice is blazing fast... 3-4 hours and it's back to a 100%.
Okay, this will sound too silly but this worked for me! Encountered and suffered from the same problem..
It used to take 8 hours to get fully charged...but in time i noticed this silly and weird thing...should work though..
Before putting the phonw on charging, kill all running apps...then when you plug the charger-DO NOT TURN THE SCREEN OFF BY YOURSELF...let it sleep automatically. And it'd get charged lighting fast...it worked for me!

If i put my Note 2 on charge where its at 25% battery, in 30 mins my battery gets charged to $85%! And you should ALWAYS use the charger that comes with your phone instead of a charger made for another phone. The HTC charger is designed to charge that HTC Phones battery. Each charger is different in the sense it provides different amounts of power. The Note 2 battery is huge so the Note 2 charger is designed to push a specific amount of power to it to charge it in a reasonable time.
For e.g. If you use the iPhone 4 charger to charge an iPad, in 5 hours it will charge the iPad to approx 50%, and if you use the original charger to charge the iPad the iPad will be more than fully charged. Thats because the iPad charger is designed to accommodate the huge battery inside the iPad.
Also i read an article not too long ago that said that alot of science goes behind these smartphone / tablet chargers and how its dangerous for the charger and device / battery if you start mixing and matching chargers.
My $.02 cents!

Now here's the kicker... It's currently unavailable...but two days ago when I wanted to make this thread is was not even listed on Amazon, so possible restocking ? I don't know.
I killed my battery to the point of total shut down by about midnight Saturday night. When I got up about 930 am I was fully charged. Now I know we've seen longer run times leaving the charger on after 100% pops up, so to speak to that I am on 94hrs run time and have forgotten how to check Screen On Time...
I am now at that dreadfully annoying -10% level. So I can use the phone all day on 100% brightness but it will chime in all day to warn me of the coming Powerpocalypse to come :laugh:

If you rooted your device you can put an xposed module on that will eliminate all low battery warnings.
On your setup, I don't really see the difference between it and using the OGP's standard high-power charger. The cable isn't going to do anything, as far as I can see. And the charging port is 8A/5 ports — from what I've read it adapts to the device to allow it to pull what it needs within that allotment, thus I don't see the OGP pulling more than 1.8A. So, my question to you is, you've tested the standard 1.8A charger against your setup and you get X hours reduction on charge time?
FYI, I don't have the ZeroLemon pack. Thinking about it but might upgrade my device to the GP2.
I have, it took a day and a half.

36 hours to charge?
Most using this pack state around 12 hours. Seems something is wrong if it's taking 36 hours to charge with the standard charger that comes with the OGP — normal battery charges in less than 3 hours. I've seen where some zerolemon packs hit 100% but are actually only half charged, thus causing increased charge times. . . . strange stuff.
Using Yoobao 2 Amps wall charger
My zerolemon (9000 mAh) only took 10 hrs to charge. And standard battery (3140 mAh) took 2 hrs using Yoobao 2 Amps wall charger.
I was hoping someone could tell me where to find 4A or 5A wall charger near Jakarta.

This is the only electronic device I have ever owned that seems to charge slower than it discharges. I mean it takes FOREVER.
Is this a bug, a too weak charger or something else? I expected battery life to not be so great with this amazing screen but didn't expect the very slow charging. Any ideas? Thanks in advance.
When I first opened mine it was at 60%. I charged it while setting it up & play with it. It took about 3 hours to 100%. So charging is still faster than discharging but of course it all depends on how you use it. One thing I did notice is that battery drains very little when it's in sleep mode, which is great.
Looks like Samsung charger is slow. I just tried using my wife's Nook HD+ charger which also has 2.0A output and it went from 65% to 100% in 1 hour 20 minutes. I have a 10.5.
My 8.4 took just over a couple of hours to charge from 0% last night. Tablet was switched off though. Haven't tried it powered on yet.

It seems to be improving a bit now that it has a few full cycles under its belt. Regardless the Samsung charger charges my Note 3 very quickly. Perhaps turning it off completely during recharge is the answer.
Big difference in chargers, been using my LG GPad charger and it's been good about 25% an hour, last night I put it on a cheaper charger in my bedroom, was at 15% and 8 hours later was at 80%. Definitely want to use 2 amp chargers

Well the Samsung charger is 2 amps. I have noticed charging seems much quicker with the table completely off.
Charged my tab up whilst switched on last night. Was at 9% and about 2 and half hours to reach 100%. Seems good to me.

Is anyone else experiencing this problem or is it just how long it takes to charge this tab?
Plugged into the charger for an hour with the tablet off and it's only charged 15%. So it's going to take 6 and a half hours to fully charge?
Also the battery seems to die pretty quickly from just normal Web browsing. From 40 to 15% in an hr.
Battery life / charging / Simpsons tapped out lags / lots of stuttering with TouchWiz...
I want to be happy with this tab but it hasn't been easy
My battery life improves after a few charging cycles. I found Samsung charger is slow but not too bad. Mine charges about 30% an hour with tablet powered on but not in use. It goes a lot faster when using Nook HD charger, though both have 2.0A output.
My Note 3 charges so much faster that it's not even funny. And considering it's 10000 mAh...
Yep charges super slow. No idea why. Also drains super fast surfing web. People talk about getting 8 hours on this. Im lucky to get 4 but then again i like brightness high.
Use a launcher to improve Touchwiz stutter (funny that some folks complain about this stutter thing - on 10.5 have never experienced it even without a launcher).

Try to power down for a few minutes and then see if there was a difference after you powered on.
You can also check the task manager to see what is running on your system.

I always kill apps when I'm done with them. Guess I'll give rooting and removing all the Samsung apps a shot.
I got some decent battery life out of mine when I had it about 6-8 hours mixed use. Def noticed a big drop when surfing the web using white backgrounds. Charging also was painfully slow on mine I think around 3-4 hours from 0 to full charge for me when not in use.
It's been a staple of their latest tablets unfortunately. Just make sure you're using the stock cable/adapter as some of the aftermarkets don't have enough power. For example, I have a 10 foot cable but it only puts out one third the power then the included power cable using the same adapter.

Try using Galaxy Charging Current lite it helped me. I was using a Anker intelligent charger and it took forever to charge it. App showed current at 350-450mA. Used Samsungs and it showed 1800mA.
I have to agree, just received the tablet today albeit stressed out to the max because the fedex guy marked it as delivered when it wasn't to squeeze out extra minutes for a break (seriously?!?) I thought it got ripped off! So, back to the battery, I turned on the tab, beautiful this thing is by the way...and was at 62% out of the box. I began charging it using the included power cable and adapter, and 3 hours later I realized just how long this was taking to charge. Granted I was using it practically the whole time, I am hoping a higher amp charger will fix this for me.
Yup it took me 5.5 hours to charge fully. I'd be lucky if i get 5 hours of usage before the juice runs out.
8.4 inch charges fines here. 2.5 hours max, powered on or off.

Charge time isn’t particularly fast on any of the devices, but the 10.5-inch model in particular takes a while to make it to a full charge. The 10.5 will reach a 90% charge in just under 4 hours, but to make it to 97% takes another hour and the last 3% takes another 42 minutes on top of that. Usable charge time is competitive, but if you’re obsessive about always charging to 100% the 10.5-inch model does take a while to get there.

Slow charging NO charging
I hope this is okay to post here since it is a charging problem. I am on my third SM t-800. Mine stop charging all together! First one charged one time then stopped. Second on would not charge at all, It used up its factory 45% that it shipped with and nothing more. Third one was best by far and charged untill this moring and has stopped. Now, here are the details. I checked the cord by pluging into my note 3 on all of them. Infact my wifes Note 2. They charge fine. I don't have my ameter to check ampers but they clearly are delivering volts to the other devices. Now get this. I have a Bose external speaker that uses a mini usb. I plugged that one into the tablet and it is charging right now. Of note I had a concern that maybe some how the socket was bumped on the tab and somehow messed it up. But that is a long shot since the first two were used while only on a desk. So this third one has been supper "babied". I'm so frustrated right now.
BTW my first tab charged very slowly. 6-7 hours or so. Maybe more? I feel at this point the pins in the tab are not making contact. Any thoughts?

Just got of the horn w/ Samsung. Got issue taken care of. In short, the phone tech mentioned ampreage and I yanked the AC transformer off the wall and checked it. The factory transformer is 5.3v. 2.00ampers. In the dark last night i plugged into a "white" charger. An ipad charger I think, that is 5.2v. 2.4amp transformer. I switched the cord to the corect transformer and the tab is charging. Apparenty the chip in the tab was protecting the unit from over ampreage and it shut down charging. I know better than this and feel like a fool but thought I should let you all know what happened. This brings up a issue. Slow charging.... could the slowness be caused by a transformer with say 1.5 amps? Maybe the tab will let it charge but at a slow rate? Just a thought. Moral of the story for me? Plug in the tab in a lighted area, and into the correct charger.

Charging is a little slow, but the battery is large, so i accept that, but when it's charged 100% it lasts for ages. Faster charging shortens the life of the battery anyway. I could easily get 7- 8 hours constant surfing out of this tab. I've been on it now for over 2hrs surfing and it's used 13% . I always use auto brightness.
I get 6-8 hrs of mixed use, YouTube, surfing the Web and some movies with a little gaming. It takes me around 4 hrs to fully charge. Battery life is average. I'm using a 10.5 LTE.

Technically this is not true at all. It is heat that hurts batteries. You can charge as fast as you want as long as you keep it cold. That being said, Lithium Ion batteries will take a much faster charge rate and not cause heat. You could easily charge this battery in 2 hours, but the common chargers aren't that powerful.
I have a issue with my pixel 2 XL charging slow, usually taking 4-6hrs to charge from 15-20 to 100%. I had google troubleshoot it but seems nothing can fix the issue. They asked me to replace my phone twice and I even got new cables and adapter but the same issue alerts occurs again and again. I even tried switching ports and tried outside my house but the charging time is still slow. I even tried in safe mode and still same behavior. Any advice that i could do good with?
Thank you!!
Same here. Went from @ 2 hours to fully charge to now taking 5-8 hours and won't charge at all while being used. Google issued an RMA but the link hasn't worked yet. Talked with 2 other Google reps and no one can figure out the problem. I'm doing advance replacement so I won't be without my phone for 2 weeks.
Hi, i was experiencing the same problem, but I have this workaround and is working, this battery is Li-Ion, so they don't like cold temperatures, install AccuBattery and check battery temperature before charging, try to warm up the battery to 23° or higher to start the fast charging (PD) capability of the Pixel 2 XL, this have worked for me everytime.
Doesn't work. Accubattery is how I knew how slow mine is. 490mA charging versus my daughter's 5x at over 1400mA. My battery is 86°F right now and nothing is different. Tried that after seeing the article last week. Seems mine changed after the February update.
Im experiencing this as well, rather annoying.
From my personal experience I have noticed that my device usually charges at around 3000-3400Mah while the screen is off, once the screen is turned on though it will drop to 1000 or below. This is a feature to keep temperatures down. What does accubattery say your screen off charge rates are? I will also add that I am on a custom ROM.
Sent from my Pixel 2 XL using XDA Labs
Accubattery shows average of 491 for screen on and screen off.
I noticed that when I first plug in the charger, accubattery shows charging well over 1000mah but after a few seconds it drops back down to the 4-500 range. Temp seems to be irrelevant, it was in the high 90s when I noticed this.
I'm having this 5 hour charge issue as well, but I started using an old moto z play stock charger and the phone now charges in like 1.5 hours. Crazy.
I guess this Picel 2 XL "slow charging" issue is quite a known issue (kinda glad actually for finding out I'm not the only one)
But my problem is that this "slow charging" issue gets even worst, my Pixel 2 XL sometime wont charge at all at the first attempt in plugging in the charging cable. And Now I have to make sure the "charging" icon is there when I plugged the charging cable sothat it will keep on charging till full (kinda annoying actually)
This started to happen to me about a week ago, while before that it only took me 2 hrs or so for having a full charged. anybody else care to share their experience e.q. when this is start happening to you guys or does the "slow charging" attempt always sucessfully charged when you plugged the cable or not (like what Im experiencing right now).
Do you guys return your phone?
Thanks in advance...
I have been using my og pixel XL charger and works way better than the pixel 2 xls. Seems to charge about 5 mins faster.

I've had slow charging issues with all the custom roms. Plus the phone in with Ambient display, says slow charging. On a stock Rom, same thing, and it says Charging rapidly, and it charges faster.
Been posting on a few rom threads about this. All sorts of theories. Using stock charger/cable. They work fine with the stock OS installed.
