[Q] Charging Galaxy Nexus

I noticed that it takes about 2 hours to charge the battery from 0% to 100%
Do you guys leave it plugged the phone in for the night ?
Battery's life is great so far.
12 H
Screen on for 2.30 hours.
Calls 1.5 hours
1 exchange account
2 gmail account.
And still 20% left when I get back home.

I hate it. The battery is really bad compared to the GS2 that I had.

I was shocked at how bad the bat life was when I first got the phone but after a few days it really improved. I know you tend to use it more the first few days cos its new but I believe it also has something to do with how the phone calibrates the battery which takes a few days to do. Not entirely sure of the ins and outs but I know clockwork mod allows you to wipe the battery stats presumably undoing the battery calibration... something you prob only want to do if you are flashing a new rom that is supposed to be more efficient with power.

Yeah my batt life has improved compared to when i first got it. Compared to my Vibrant this phone charges faster from what i can tell. I also made sure im using a 1.0A rated charger. I found an OEM Samsung 1 amp charger on Amazon since my Nexus came with a UK plug and i didnt feel like using an adapter. Ive also used my ipod OEM usb charger which is rated the same output.

I don't leave my nexus on the charger anymore. Standby time is so good there is no need. And yes I also noticed this phone charges pretty fast.

How long does it take for your LTE Nexus to fully charge (on AC, not USB)?

I know there are a lot of battery threads out there, but I can't seem to find any that deal specifically with the issue I have and it's got me worried.
I understand that USB charging is slow no matter what, and there's already a thread about that, but even when I plug the device into the wall (AC charging), it takes at least 3 1/2 hours to charge from zero. I timed it last night, and in a matter of 20 minutes the battery went from 73% to 77%. This was with 3G on and the screen turned off. If I actually use the device while charging, it may jump 1 or 2% in 15 minutes.
So, my question is does anyone else have this issue, or do I have a bad battery/device?

Not sure what's wrong with yours maybe your using a charger other than what came with the phone. Mine charges from zero to 100 in a little over a hour. Feels like faster than that lol I was actually amazed how fast this thing charges.

Hmm. Def. something up, then. It takes for freakin' ever to charge even sitting idle the whole time. I'm going to drain it again today and let it charge again and time it with the stopwatch app on my tablet.
I also ordered the extended battery from vzw for $25. Hopefully that will help.

Working on battery stats atm over at RootzWiki. Far from complete.

@ 1 amp mine charges about 1% a minute if I'm not using it. If I'm listening to music it goes to 1.5 mins a percent. With the screen on and actively using it takes about 2-4 mins a percent.
Sent from my Galaxy Nexus using xda premium

Im still using the standard battery and with my phone on a full charge from ~10% takes 1.5-2 hours on the other hand with the phone off its 0-100% in about an hour...

GSM here. 1 Hour charge from 0 to 100 on average.

How long does it take to charge GS3?

My GS3 takes about 3-4 hours to charge from 0% to 100%. I am on stock and am using the OEM wall charger that came with the phone. Is this normal?

Mine takes around an hour or two I believe it used to take around the same as yours but it doesn't last as long. But how long does yours last

Mine take over 2 hours from 5% to 100% using stock wall charger,,, 3 to 4 seen like a lot.

The answer is... it depends.
If you're charging with the phone on, it will take longer, if you're charging via a usb port, it will take longer.
If the phone is off and you're using the stock wall charger, you're charging at a maximum of one amp. If you have a stock 2100mah battery (2.1 amp-hours) and your charger is 100% efficient (never happens), the best possible 0-100% charge time is... 2.1 hours, it really is that simple
Now, you're not getting 100% efficiency, plus the way lithium batteries charge, at around ~50% capacity, the charge current steps down gradually from 1 amp to nearly 0 amps, so your real full charge time with phone off is probably going to be closer to 4 hours than 2. The step down is necessary to avoid over-charging. The logic (usually in the battery itself for phone batteries) to determine full charge is when the battery reaches 4.2 unloaded volts. Charging current will increase the voltage reading, so as it gets closer to full, charge current is gradually stepped down to maintain the 4.2 volt full charge state. As the current approaches zero and volts stay at 4.2, the charge controller knows that the battery is full.

3 hours is the average using the included 1amp A/C charger.
Charges 10% about every 15 minutes for 0% to 90%, and charges the last 10% in about half an hour.
(don't bother trying to charge using your computer's 0.5amp usb port, though; takes forever, especially if you're using it while charging)

There are reports that the charger that came with the s3 is garbage.
I was using the s2 cable to charge and it took approximately 1.5 hours.
Now it's taking 3 - 4 hours.

The charger that comes with the S3 is NOT garbage. I tested charging times against a "better" 2.1amp charger about a month ago and there was no difference. (If your custom kernel supports "fast charge", then there'll be a difference, but your battery will suffer. Better to stick with 1amp)

Flashed JB today. Phone currently charging. Started charging at 2%, now at 41% and it's been 45 min. Estimate completion time, 1 hour 45 min.
So the culprit is not the USB charger, but rather something I had installed on ICS. I suspect it is the launcher I was using, which was GO launcher. Prior to JB, i was using apex and it was charging a little bit faster than GO, but still wasn't acceptable. I think it was 3ish hours for full charge.
My current JB setup is pure stock launcher and apps.

With stock charger it takes my phone approximately 2.5 hours to go from 5% to 100%.

I can confirm that,my AT&T S3 has been charging with that charger for 6 hours and I am still showing a 50%,so I had to grab a Motorola charger and it went up from 50% to 73% in half an hour.
Freaking Samsung,there's always something.

I'm on Slimbean 4.2.1 RC1 w/ lean kernel and my phone will usually last (with average daily use) about 3 days on one charge. The rom/kernel supports fast charge so I can get it from 0-100% charge in under an hour and a half. On stock rooted rom I was getting maybe a day and a half of battery life. Darned AT&T bloat lol

So how do we decide the most efficient charging method possible? How do we look at the Amperage of the battery and the amperage of the charger and decide what's best?
Also what's faster? Wall charging or fast/quick charging to a USB line?

Fast Charge will make it charge the same speed the wall charger would (but breaks storage mount while it's turned on).

This doesn't mean you battery is "on charge" for all the time... once the battery is 100%, the charge changes to something called "trickle charge". At this point charge does not happen continuous, but like a trickle to maintain the 100%.
Pull the phone out at the end of 8 hours of charge, and notice how quickly it goes to 99. Pull it like 10 mins after it says full, and it takes longer to go to 99%.

Higher amps charge battery faster... but... at the cost of capacity... At approximate 10% more charge than the battery is optimized of, it kills the battery by as much as 30% sooner. So its not really worth that. At the same time lowering the amps by 10% increases life by about 20-30%.

Does charging take a long time for anyone else?

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

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

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.
