Charging - Nexus S Q&A, Help & Troubleshooting

How long does it typically take to fully charge your phone from about 30% or so? I have noticed that it takes really long to charge, I have had mine on charge for 4 or 5 hours and its only at 88%.

Usually about 3 hours here.

Same, I would say about 3 hours.

I'm going to let it run down and time it. Something is definitely not right. If I put it charging when I go to bed it is not fully charged by the time I wake up.

Thread moved to Q&A.

Well the default charger is 0.15A right ?
I am using my Galaxy Tab's charger which is 2A and i get a full charge in like 1 hour.

The charger that came with it is a .7A I am using a 1A though.
I think I might have found the problem. The app "craigsphone" installed a service that was using 79% cpu. I tried killing it and it would come back. So I uninstalled it, now just have to test out to see if it charges faster.

I bought my phone on it's release day, and up until about a week or two ago, it's taken a VERY long time to charge up -literally all night long. But for some reason, it seems to have started charging faster here recently. It now only takes about 3 hours to charge up, from being near completely dead. I don't understand why this has apparently happened, but I'm not complaining lol.
-of course, I'm speaking of charging via the included wall charger. USB charging still takes all night for me

ikarma,
it depends on your charger.
I have 2 chargers:
- Original from HTC Desire
- Unknown brand
Both produce output 1000 mA (1A).
The time to charge from 4% to 100%:
- HTC charger = 4 hours
- Unknown brand = 6 hours
Here what I have done to this finding:
http://forum.xda-developers.com/showthread.php?t=917075
So again, it depends on your charger!
Probably my unknown brand does not really produce 1000 mA.
Bottom line, there are different quality chargers out there! Choose wisely

Extremely slow charging

Has anyone had a problem with extremely slow charging? I would plug my phone in and wake up 6 hours later and the phone is still not charged. It's even worse now with the extended battery. 7 hours worth of charging and I'm only at 85%. I'm rooted and using the de-bloat rom without the kernel, but it was like this even before the root. Has anyone else encountered this strange issue. I have been using the stock HTC charger.
mine charges in a couple hours using the wall charger and wifi hotspot. In the car or via computer USB, it charges very slowly and if wifi hotspot is on, it loses charger over time.
I typically turn my phone off to charge; speeds things up 2-3 fold.

Mine doesn't even take an hour . Power it off and try it that way and see how long it takes.
damn mine charges super fast compared to my nexus s i had
If you have plug to the computer it might take longer but not 6 hours, on the wall it only takes like an hour or two to be fully charge.
If it's an issue just take it back and get another one.
Yeah I might have to return this phone. Do you think it matters whether I use the cable that came with the phone, or a regular usb cable to charge.

You need to look at the power ratings of the adapters you're using. This behemoth phone can receive 1000ma, while many car and home chargers (like Droid1) are only rated at 500ma. I'm still trying to figure out what the power draw is on the phone when just idling (battery monitor widget is hard to understand), but if the phone draws 250-500ma with regular usage, its going to lose charge plugged into USB (rated at 500ma per port) and running hotspot (drawing closer to 600ma). That's -100ma.
These numbers are guesstimates. I'm not sure if the cable itself can pose limitations, but would suspect that as long as there's no shorts in the wire, it would be able to handle any of the above currents.

yeah i find it impossible to charge the thing on USB, and it takes forever plugged into the wall with the charger it came with.
Had an evo, and it would almost full charge (from the time it said to plug it in, so 15%) in about an hour and a half. The thunderbolt seems to take 3 hours ish for me. I know I can turn the phone off, but since it usually charges over night its not a big deal, I just think it is interesting that it is so different.
yeah I'm one of the folks who charges FAST. It has really surprised me...I actually thought everyone was charging super fast until this thread.

+1 on looking at your adapter. Use the one that comes with the phone or make sure that it's rated at 1000mA/1A or more. I tried a MicroUSB adapter I had lying around that came with a bluetooth headset; turns out it only puts out 200mA, so the phone would take forever to charge on it.

with an output of 200mA I would be amazed if you could get this phone to charge at all, without having a custome kernel and underclocking the processor. If anything I would see it maybe staying same battery percentage.
Overall I feel this phone does charge really slow. It is way slow charging on a computer. I was charging it and just doing some light texting and after 4 hours the battery only went up by like 25%.
I have a second wall charger rated at 1000mAH, and after 30min it went up like 10%. This was with the phone off btw. With it on, but not in use, it went up like 4% over 30min. I'm kind of surprised how long it takes to charge. I've had no problems charging it at night. Plug it in before bed, and its full when I wake up. How does the 1400mAH battery size compare to other phones?
I did a little math too, the battery is a 5.18 W/hr battery. So with a 1AH charge at 5V, you'd expect the phone to charge in 2 hrs if only about 50% of the electricity is getting retained by the battery.
I've noticed that mine takes about 1hr 45ish mins to charge from completly dead. My Droid used to be an hour at the most.
i just checked on the adapter it came with, it's 200 mA...did people get better chargers than me or something? Mine takes forever to charge also...been stuck at 99% for 30 mins
EDIT: nvm, i was looking at input, not output...still isnt moving from 99% to 100% though

@lorijuan1024 im with you man the Nexus S took forever...... To charge
its impossible for me to charge it through the computer, it went up 5% over 3 hours, wasnt on hotspot, sending texts.
Mine charges fine on anything, I am using my old fascinate charger.
Charging speed seems to fluctuate for me... sometimes I get lucky and its fast. Other times, not so much.

How long does your Nexus S take to do a full charge?

Hi guys, just realised my Nexus S takes pretty long to charge up.
Hoping for more users to come in and share ur charging time and also to check ur charger whether it's rated at 0.7mA for output?

How long is "pretty long"? Mine takes around 3 or 3 n a half hours usually.
But when I used my iPod's wall charger it was comparatively faster. iPod's is 1mA.
my wall charger is 5v/0.7a, takes around 3-4 hours for a full charge, but i leave it to charge overnight ready for the morning so not 100% sure
after charged to 94-95%, stay with display on and will charged to 99-100%

Define the "pretty long" term.
All Nexus S's come with the 0.7A wall charger. So the math is the following:
1500mAh / 700mA =~ 2h - DC current
1500mAh / 500mA = 3h - USB plug
So it should take aprox. 2 hours for a full charge with the wall charger, 3 hours with USB connection. That's theoretically speaking.

at least 4 hours on the wall socket.
Mine takes around 4 hours too. My Captivate runs circles around my Nexus S while charging. But the battery on the Nexus tends to last longer running the same programs. Both have 1500mAh.. Weird.

About four hours from 1% to full via wall socket. Give or take a little.
I use Battery Monitor Widget to track what is going on during charging. To avoid blowing up the battery, the charging circuit pulses the battery with current and a different profile appears to be used on USB as opposed to AC. I tried a heavy duty USB wall brick and it made no difference (1000ma/H) - the GNS still reports on USB charge so the AC wall charger has a wiring difference to USB. Some say the data lines are shorted on the AC charger telling the GNS that it is plugged directly and flagging the higher charging profile.
Basically the AC circuit takes about 3 - 3.5 hours and the USB circuit can take 4 - 5 hours. USB plugs are limited to 500 mA (or USB 1.0 used to be so I am concluding that USB 2 is the same). Anyone know different ?
The 97% charge limit seems to be the circuit limiting overcharge of the battery and if when fully charged you disconnect the charger and immediately reconnect you can squeeze an extra 2 - 3 % in to the battery. Mine reports 99 or 100 after such a cycle.
To make sure your GNS battery circuit is fully calibrated run the fone completey FLAT once in a while (50 charge cycles). This makes sure it knows what is flat and what is full. Before I did that it could take 4 - 5 hours or more to charge. After flat cycling, it is quicker. Use Battery Refresh Beta (maybe full version now) from the Market to flatten the beast........
All this assumes the stock 1500 mA battery pack. Anything else (1400 cheapies labelled 1600 or a fat 3200) will be different.
This is in stark contract to my XOOM which doesn't pulse at all but simply wacks 1500 mA in to the battery until it is full. Maybe heat disappation is not such an issue on the XOOM. I can't imagine the battery techology is much different but I don't know for sure.

over 25 hours to charge note 10.1 ?

Hi I just bought a used galaxy note 10.1
it did not come with a usb wall charger
after 7 hours of charging
a search said its my usb charger
I was wounding if it is normal for this to take over 24 hours from 0% battery on a charger like this
that only gives 0.5 A
or am I doing damage to my battery by leaving on charge for longer than 24 hours
its like a incredibly slow trickle charge
right now its almost full it claims but im not sure if it will ever be full at this rate
I thought maybe 24 hours but now its 1 hour past 24
I was trying to (calibrate the battery )
so I let it die to 0%
I turned the device on half way though charging
noticed it had an x though the batter so I freaked out and tryed plugging and unplugging it like 10 times
I was wounding how bad that might be for the memory of my battery to do something like that
because I unplugged it before it got to 100% when i was attempting to calibrate it
Im not sure how sensitive these batteries are
but your input would be much appreciated
You could use an off brand iPad charger with your USB cable to help it charge faster your typical phone charger will only give off 0.5 ma, so look for one for a tablet

to leave it plugged in now approaching 28 hours
the charging logo on the screen appears to have approximately 75% charge so far
I want it to get to 100%
should I unplug it if its not charged in 6-8 more hours
im mainly wondering if it is even possible to fully charge to 100%
on a old ipod usb charger or not

You are not harming your device. The only negative is that it will take longer to charge. The red is normal when not using either the correct type charging block or usb cable, it is not harming your tablet.
I would just do what some of the other posters have suggested, getting a new charger made for a tablet, just because waiting that long for it to charge is not practical.

SGN 10.1 GT-N80XX series need a specifically designed charger for them.
One thing for sure, it need to provide 2.1 A, 5 V & most phone charger only supply around 0.5 - 1 A.
Most 3rd party charger also only supply around 0.5 - 1 A.
The other is the data pin(s) & it quite different with Apple's charger.
I've tried several 3rd party chargers & Apple chargers (iPod,iPhone & iPad) & most of it unable to charge my N8000.
You need to buy an original charger for your device.
Or you can try buying 3rd Party N80XX charger on eBay from a reputable seller.
That being said, you also need an original cable to be used with the original charger.
Most 3rd party cable can only supply 0.5 A & some 3rd party charger can only be used using specific 3rd party cable.
A long 3rd party cable (10 ft / 3 m) usually can only supply around 1 A.
For example :
I have a Powerbank that uses its own cable to charge at 2.1A rate, but I can't use my own original cable with it
But my original cable is fine & I uses it to charge using my original wall charger.
It takes around 4-5 hours from 4% to 100% (with WiFi ON & all sync on)
0.5 A can't charge your device while in Power ON condition.
To charge at 0.5 A rate you have to turn OFF your device & it will take a long time to get 100%
(N80XX series have a 7000mAh battery so you can calculate how long).
NOTE:
The battery with red cross icon means that the charger/cable isn't designed for N80XX (usually the data pin settings is mismatching the original design), but it will still charge your device at a very low amperage (lower than 0.5A) to prevent damage for using inappropriate charger.

yes I will as soon as I can
thank you
I am still a little worried that It will never make it to 100% with the only one I have available for now
does not really sound like anyone has had the patience to let it go to full with this slow trickle
Amazon has the chargers and cables.

[Q] Charge Time

I am a bit surprised at how long my shield tablet takes to charge, around 6-8 hours depending on how much battery is left (usually around 20% before I charge).
Is this normal? Or are my expectations a little too high in thinking it would take 2-3 hours to charge?
Many thanks for for answers!!
What charger are you using? Mine doesn't take that long and I'm using NVIIDIA's retail charger (2.1A).
I am using the wall charger that is supplied with the tablet!!
I have spoken with nvidia support about this issue, however they couldn't confirm the charge time for some reason, hence why I am asking here for peoples experience with charging times. Also I have tried googling the answer and haven't found anything!!
Slightly frustrating!!
43 views so far and no answer?
come on people, all I am asking is your charge times for your shield tablets!
pretty please with cream and a cherry on top?
I havn't any exact number for how long the charging take, but I think the charging time has increased with Lollipop. Most of the time it is fully charged over night (6-8 hours) but sometimes it has just charged a few percent.
I have seen some unfortunate charging times as well, but I haven't recorded them or taken note of exactly how long they take. I also have chargers up to 2.1A and thicker gold plated cables I've tried.
Are there any apps I can use to record battery percentage by the minute?

What are we talking about? Time to go to 100% battery or time to go to green led?
There is a 30-45 min time difference between 100% and green led.
When my shield reaches around 20% i'll charge it over night whilst I'm asleep, 6-7 hours later when i wake up i still see the orange led and am surprised at how slow it takes to get to 100%. This is how I noticed the slow recharge time.
Admittedly this is my first tablet, and as stated I'm just surprised and lead me to think maybe the charger that was provided is a dud and/or the tablet is a dud. And no one likes a dud!!
However I just wanted to hear other peoples experiences as maybe the charge time is this long and I've just got too high of an expectation that a device like this should have a charge time of 2-3 hours.
Many thanks for all the responses so far, most appreciated. Keep 'em coming!! :good:
If you want 2 - 3 hours of charging time starting from 15% or 20, you have to get another charger. The stock one is weak. I got a Samsung Note 3 one and after 2 hours and a half, or even less depending the percentage, it's fully charged.

^^^This.
Also, I have a Quick Charge 2.0 charger that I found on Amazon that shows whether or not a device is capable of using the Quick Charge 2.0 standard. My nVidia Shield does, in fact, seem to support it, and charges pretty quickly on this charger. I can't say I've ever had the tablet get below 50% or so, but I've never seen it take more than an hour or two to get the Shield's charge indicator to go green with that charger.

18W. However, in the normal 5V mode, it's only 10W, like any other 2A charger.
In QuickCharge 2.0, the device being charged decides if/when the charger uses the 5V, 9V, and/or 12V charging modes. If the device is not QC 2.0 compatible, the charger will ALWAYS charge at 5V. This particular charger indicates when the device has allowed it to shift into the 9V or 12V charging modes (but unfortunately doesn't indicate which). In either of those modes, it's 18W (which incidentally is about 4W more than the Moto "Turbo Charger").
I've seen a 30W charger on Amazon (which is the maximum, according to the standard), but it doesn't have the indicator. This is important to me, because QC 2.0 needs a full data cable to communicate with the device. Accidentally use a charge-only cable, and it will stay in 5V mode. It's nice to have that warning that you've done something wrong.
However, in this case... that indicator showed me that my Shield had a fantastic unadvertised feature (at least as far as I knew).

Seems you have a problem, mine doesn't take more than 4:30 to go from 15% to green light.
Actually, using the stock charger, it only takes mine about 3 hours to fully charge from being dead.

I don't think so
Correct me if i'm wrong but the shield battery is 6900mAh.Stock charger is 2.1A... So what you are saying is impossible.
Doesn't charging a battery faster degrades it? Like, the faster you charge it the hotter it gets and the fastest it degrades overtime? And the same can be said of the opposite: the slower the better for the battery longevity?

Yeah, high amperage kill your battery faster, take care about "quick recharge" charger. Try to avoid long charge too. Don't forget : 1 cycle on Lion-ion battery don't mean 1 charge = 1 cycle. 1 cycle = 0% to 100%. So you can charge 20 percents at job, 10 percents in train, 70 percents at home.

See my post just up there. 6-8 hours is too long, maybe battery fail...
Thanks for all the replies guys, most appreciated!!
I have spoken to Nvidia Customer Care and I thought I would share what they advised me to try (which may or may not help others are experiencing the same issue), not sure if this will work or not, but at least it is something to try -
"We would kindly request you to follow the battery calibration producer mentioned in the steps below, observe the device performance and let us know the result.
You will have to calibrate the battery for just one time and observe the device battery backup for 2-3days to see the changes.
1: Drain your Shield tablet battery by using it normally until it turns off by itself.
2: Power-on your Shield tablet, if it wakes up and if you see some power left, follow step 1.
3: If Shield tablet is now drained to the point it can't wake up, set the device to charge for 7-8 hours.
The device should remain off when you set it for charging here.
4: Unplug the charger after 7-8hours, power on and wait for the battery charge to drop down to 90-95%.
5: Once the device battery drops down to 90-95%, plug in the charger and charge for one complete hour.
6: Unplug the charger once the device is fully charged.
7: Go to Shield settings > Shield power control > Apps> select optimize all option.
8: Go to Shield settings > Shield power control > system>
• Set the brightness to auto.
• Change the sleep option to 2 minutes of inactivity instead of default 10 minutes inactivity.
• Change the processor mode to either optimized or Battery savings.
• Check the Wifi optimization on.
Observe the device performance and report to us if you are still facing issue with the battery backup.
For better battery backup and optimization, you may also consider following steps.
1: Always use the Shield tablet charger and not the computer USB ports or any other charger as the power specifications vary from the device to device.
2: In case if the charger is missing, use the back port of the desktop computer to charge the device instead of front port.
3: Always remember to exit the application instead of tapping the home button which will continue to run the application in the background.
4: Restart your Shield tablet at least once in a week. This will refresh the device making it work faster and efficient.
5: Connect the charger only when the battery comes down to 15% and unplug the charger only when it reaches 90% or above. This will reduce the number of charge cycles which will make battery last longer.
6: Use a third party app manager like Clean Master and free the memory at-least once a day to keep the device running faster. "
Fingers crossed this helps.
Your charger is faulty I believe, same as mine which Amazon and Nvidia themselves said was faulty and I got a partial refund due to that. I would suggest you to get some other charger, that charges at like 2.1A as they charge the tablet ridicolously fast (about 2,5 hours from 20%) and I'm finally able to play games while charging too (however, then it charges at a slower rate).
I made a thread about this not so long ago:

Huawei Fast Charger is slow as heck

I have imported my Huawei and I absolutely love the phone. Since it is an import it came with a UK Type fast charger. I simply used a wall adapter and powered it over the US current. Well, that fast charger isn't working what so ever - after 2 hours I only go to about 35 percent from 0. I have used my Note 7 charger to charge it, and there the charging times are much faster. Any ideas on what, if anything, I am doing wrong and maybe where I can buy a working Huawei charger. I can't return the charger since I bought the phone over Amazon and it strictly came with no warranty. It is not the end of the world if I can't use the included charger I just want to see how fast this phone truly charges.
Either this post is a joke or someone sold you a non supercharge Huawei charger. Also are you using both the charger and charging cable that came with the phone in the box. It's white with purple in the USB A area
Here from 10 to 80% in 45 minutes
Same here. I find the first 80% to be lightning quick and then it slows to a "normal" charging speed for the last 20%.
Must be something wrong with your charger or cable.

Using the european adapter, not the UK one, but charging is lightning fast for me as well.
hi
the orginal adapter and cable
i charge from 0% to 90% in about 55 minutes, the last 10 % are slower maybe 30 minutes to full

Mine took almost 2 hours from 48% to 100%. I'm using Original Huawei charger.......
Install ampere and see what the milliamp charge rate shows as. When the battery is almost dead it should charge at just under 5 amps and will slowly decrease as the battery level increases.
Mine typically goes from 0 to 65% in half an hour, then 90% around half an hour on top of this. The final 10% takes almost another hour.

Well there is obviously something wrong with your charger, cable or phone. I would guess the first two.
Mine turbocharges in a few minutes. I've been using fir about a year now.
Could be that an "European" charger intended for 220 volts does not provide rapid charge when plugged into a 110 volts wall plug. I have for example an electric toothbrush I bought here in Europe and it refuses to charge on a 110 volt system when using an adapter. Maybe see if you can buy an OEM charger intended for the US?
There are 2 different chargers that are official, there's the supercharge one that comes bundled with the phone which I guess everyone is using and is getting great charging speeds... (Gotta use both the charger and the cable)
And then there's the fast charger which is pretty slow compared to the bundled charger.
The next time you wanna travel abroad make sure you buy a supercharger for that regions type of socket.

If you buy a replacement make sure it actually says SuperCharge on it.
