[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

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.

[Q]Battery not charging to 100%

When I wake up and take my phone off the charger, it's always at like 98 or 97%. I have battery monitor and when looking at it, it shows that it gets to 100% through charging, then goes down to 98 or 97 and then stays at that state throughout the night.
Anyone else having this happen with their phone? With enough battery issues, it seems these 2 or 3% could be an hour of standby.

When the phone hits 100% on the charger it doesn't charge anymore to prevent overcharging.. pretty common feature in most phones nowadays.. if it goes below a threshold it charges again until 100 and the process repeats

same issue... my thunderbolt use to hit 100%, but the gnex stops at 99 or 98%. if i unplug the charger for few seconds, plug it back in and boom it goes to 100%

Same issue here. Seems to stay on 99 until I unplug charger and plug it back it.

If you want to get 100% (not saying it makes a difference when it's showing at 98/99%, what volfman suggest it the best way to do it. I did it with my SGS2

it should charge to 100% in the first place. another bug that needs to be fixed... hopefully the 4g gets fixed first cuz with this, i can live with.
The reason i want `100% is cuz its nice to see the 100% rather then 99%.

[Q] How long does it take you to charge your GN (GSM)

I hope it's not just my phone but does it take a long time for you guys to charge from 0-10% to 100% battery life? I'm not even exaggerating but it takes about 4-5 hours for my phone to fully charge.
1) I charge it through the wall outlet. I have no problems charging my 4S on the same wall adapter and outlet.

It takes me max 2 hours. Through the wall

It takes me just about 2 - 2.5 Hours plugged into the wall. I have the standard battery.

Crap, must be a defect with my battery =( I'm timing the charging right now and its been 55 minutes and it's only at 27% Started from 0%.

It takes me 1 hour and 40 minutes to charge from 0 to 100 with the wall charger ( GSM version)

Thanks for the input, I guess I have a defected battery or something. I'm going to see if the battery gets any better before I buy a battery replacement.

You could calibrate the battery ( charge to 100% and wipe the battery stats in cwm ), if that doesn't help i would go back to the store and ask for another battery cause it should charge from 0 to 100% in 2 hours max
Sent from my Galaxy Nexus using xda premium

the rate of chaging is depending on the output current that your charger have... my original charger have a rating of 5V 1A 0%-100% requires me a good 2hours leaving the phone ON in standby
5V 700mA chargers gives requires me 2.5 hours from 0-100%

Takes me less than 2 hours to go from about 15% to full 100% charge on the GSM GNex.

Since getting another battery would be a hassle for me, I decided to root and wipe my battery stats like you instructed. Wasn't planning on rooting or anything since I wanted to run stock for awhile but let's hope it fixes the battery issue. Thanks for all your input guys. Appreciated and +1'd for all.

Cdma GNex here. I've been a nexus user since the nexus one. This is bar far the fastest nexus charging phone if not phone in general that I have seen.
Definitely less than 2 hours

Baterry issue with the ZL

My battery in my ZL drop fast, it is charged at 100% for several hours, when I unpluged the electrical socket, it's at 99% in less than 3 minutes. My iPhone 4s will last for half a hour before drop to 99%. What is going on with the battery life?
Sent from my C6506 using xda app-developers app

Well, as i have readen several battery care threads here in xda, the charger, when the battery is full, to prevent overcharging or something else that may damage the battery, (correct me if i'm wrong) it stops charging until 99% or 98% and it charges again to 100% and then it keeps doing the same all the time until you unplug the charger (just in your case that you disconnect the charger when it's recharging again when it's almost full) That may be why.
Hope this helped
Sent from a phone >.<

That is strange because I do not see while charging when it hit 100% to go back to 98 or 99%. Not even my iPhone when I got it did this. (I sold it)
Sent from my C6506 using xda app-developers app

It damages the battery if you charge it to 100%, that's why most phones stop shortly bevor the battery would be completely charged. So if it shows 100% it is not really at full 100, that's why it drops right back to 99. That is also why it takes less time to go from 100 to 99 then from 99 to 98.
The iPhone does the same, it just stops at 99 and tells you it would be at 100 (it's actually cheating 1%).
These methods are build in because people love to charge till it reads 100, so they don't damage the battery doing that.
Also, remember the numbers you see is not really the true charge of your battery.

Very slow charging...

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.​​

Mine seems to charge quicker than what is stated on that chart. Will have to time it from 0% next time.
Sent from my SM-G900F using Tapatalk

The charger that comes with the tab s is the same all new galaxy devices are shipping with. They do 5.3volts instead of just 5 volts. You will get a little quicker charge with the stock charger.

I get a legit 6-8 hours SOT mixed use

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.
