[Nexus 7 General] nhutquang972012:
I use OEM charger + OEM cable and it takes 10 hours to charge.

So I buy a new charger from ASUS and it's just the same problem. (I even try to change kernel, cable)

And then I use Blackberry charger with 0.75A and it charges but unstable, sometimes, it charges very well but sometimes, it charges very slowly.

Now I'm using Paranoid Android 2.99 beta 9.5 with stock kernel and charging with the Blackberry charging, first it's fast but from 50%, it takes 20 minutes to get to 51%.

Please give a suggest. :(
[Nexus 7 General] DonS:
I think I can clear up a lot of this

Its time to lay out some basic electricity and charging information so that people understand how charging works.

All USB chargers put out around 5 volts, but the amperage ratings vary widely. For those of you that don't fully understand volts and amps, I'll compare it to water pressure in a hose.

Volts is like the pressure, and amps is like the volume. So lets assume we are connecting different hoses to the same faucet. This means the pressure is the same. If you connect a larger hose, you'll get more volume (like more gallons or liters or water). Getting more volume is like getting more Amps. The Nexus tablet was designed to work with a 2 Amp charger, so that is the maximum that the tablet will use. With a charger rated at less amps, it will charge slower or not at all.

When you tablet is turned on, it draws a certain amount of current (measured in amps or milliamps). The amount of current it draws depends on what your tablet is doing. If the screen, or any of the radios (WiFi, 3G, Bluetooth, GPS, and NFC) are on it will draw more current. If it's actively syncing emails or Facebook, that will use more current. If you are playing an action game, it will use more current.

So now to how charging works. All chargers supply a certain amount of current. The stock charger supplies 2 Amps (or 2000 milliamps). If the tablet is drawing 400 milliamps to keep running, then the remaining 1600 milliamps are available for charging the battery, If you are using a 700 milliamp charger, then only 300 milliamps are available for charging and it will take approximately 7 times as long to charge. If you are using the USB port on your computer, you may not know the amperage available. The USB standard states that at least 500 milliamps needs to be available. Some computers put out twice that, so only meet that standard.

So If you want your tablet to charge the fastest possible, use the stock 2 Amp charger and reduce the current draw as much as possible. To determine if there are hardware differences, turn you tablet off and charge it with the stock cable and charger. By turning it off you reduce the current draw to the minimum and remove other variables such as radios and accounts/applications running in the background.

I've also noticed that not all micro usb cables are the same. I gave my son an HTC micro usb cable to charge his N7 16 GB and it charged very slowly. I tried to use that same cable to connect my N7 32GB 3G to my laptop and it kept connecting, then disconnecting, then connecting again. I tried two different HTC micro usb cables and they all did the same thing. That would cause slow charging because it would only charge when connected and it was only connected for very short periods of time.
[Nexus 7 General] knuckles1978:
Basic information is good. I've seen too many people speaking about current being 'pushed' from a charger etc. lol

Just to reiterate for some people.. Current is drawn by the device, not pushed into the device by the charger. And yes, it is much better to turn your tablet off while charging. That eliminates even a rogue app keeping your nexus awake using power. It also eliminates it being some kind of USB or android driver issue.

Because my nexus was an import I was supplied a cheap 700mA charger. If I was sitting playing need for speed, plugged in 'charging', the battery would actually go down. I since got a UK to US adaptor so I could use the Asus 2A charger, and it flies now. Charged from empty in about 2 1/2 hours.

But there are plenty of people also, who are doing all the right things, and something just ain't happening...
[Nexus 7 General] gerrylum:
My N7 used to charge very quickly. I recently took it on a cruise with me, and when I came back I left the N7 alone and it ran down its charge until it was dead. Now when I try to charge it, it's EXTREMELY slow. If I leave it plugged in overnight, it'll only charge about 5%. I've had it plugged into the stock charger for 3 days straight and it's still only up to about 23% charge. It's driving me crazy.
[Nexus 7 General] Oli1122:
Charging

Its to do with which model of the tablet you got an when it was made, The earlier versions of the n7 both 8GB and 16GB had a different power controller to the new 16GB and 32GB models, this along with a slightly different configuration of the internals means that they consume power at different rates :rolleyes:

EDIT: also the charger supplied with them depends on the country and shop that you purchased them from ;) and there are many variations in the amps of different chargers

Try this :D

http://www.amazon.co.uk/CostMad-Tec...s=electronics&ie=UTF8&qid=1357666577&sr=1-272

Try turning them both off an charging from nothing with the tablet powered down and you should see they are much closer in charge time :laugh:
[Nexus 7 General] atistang:
i'm not buying a new charger, i am not convinced that is the problem

some people in this thread seem to not under stand

my nexus used to charge from dead to full in a 6 hours or less, now it takes days to come to a complete charge. so far today i have been getting about 2% per hour on the charger
[Nexus 7 General] atistang:
So I tried an HTC charger I had laying around and this thing charges like it used too
[Nexus 7 General] knuckles1978:
Are you saying that the charger that you always used has suddenly stopped charging the N7 at the rate that it used to? That's very strange... Have you always used the same USB cable with it? And would you mind checking the current rating of the old asus? Charger, 2A?,, and the current rating of your HTC charger, and let me know please,, thanks,, I'm trying to get to the bottom of these strange charging issues....
[Nexus 7 General] atistang:
yes, i used the stock asus charger that came with it and that usb cable. It is a 2A charger

now here is the funny part, the HTC is a 1A charger
[Nexus 7 General] DowntownJeffBrown:
My first charge took forever but after the first change my N7 now charges at what I would say is a normal charging rate.

Am from india....using nexus 7 from 3months...on stock 4.1.2 it used to charge pretty quickly ard 3hrs max....now using PA 2.54 and today it took whooping 6hrs for 5-100% device turned off....dats pretty sad....maybe charger was displaced from his position.... let's c .....I'll try to charge with some other point and report full charging time...:)
[Nexus 7 General] knuckles1978:
The correct time with the asus charger and cable (2A) is 3 hours.

When i first got my n7, it took about double that, because im in the uk but had to get a US import because n7's were impossible to find here. The company i bought from supplied a charger. It was only 1A...

Luckily that cheap pile of crap charger they supplied me stopped working after about a week. That's when i took the US charger out of the box and noticed that it was indeed 2A. I went and bought a UK to US adaptor, and my n7 has been charging from empty to 100% in 3 hours every time.

When i was using the 1A charger, sitting playing need for speed or something with it plugged in, the nexus would actually slowly lose charge lol

But considering the great battery time you get out of these things, I'm very happy with a 3 hour charge time. It even charges at a decent rate when you're using it with the 2A charger.
[Nexus 7 General] freecity:
Thanks for posting this.

My 2A Asus charger takes 16+ hours to charge my Nexus 7. The tablet will not charge at all if it's connected to the charger when it is powered up. I tried my HTC 1A charger and it charges the tablet much more quickly in maybe 5 hours - 6 hours.

I called Asus and described the symptoms. They believe it is a bad charger and have authorized an RMA replacement.
[Nexus 7 General] soulshinobu:
32 GB Nexus 7 bought from Staples, haven't actually tested it too much yet, but I have charged it in my Biology class, which is about 50 minutes long, and it went from about 45% to 98% by the time class was over. I used the Asus charger, however, I am using the cable that came with my Galaxy Player 4.0. To me, the charge time seems to be pretty good.
[Nexus 7 General] Mungulz:
5 hours to charge for mine. Annoying because it means nothing but an overnight charge will put a dent in it.
[Nexus 7 General] SliTCX:
I don't really know how long it takes for my N7 to charge, but it should be around 7-8 hours as I charge it everyday at night (though I don't think it's good for my battery).

Do you own a Nexus 7? It should take about 3 hours for a full charge, not 7 or 8 hours.
[Nexus 7 General] AndDiSa:
I noticed differences in charging time when I was not using the original cable provided with the Nexus 7. When I was using a different cable, charging time was significantly longer, always with the same charger.
[Nexus 7 General] lolcopter:
I use a different cable, same charger, and wall charging is fine. Prob like 4-5 hours from low to full

Charging via direct usb is worthless, definitely use the wall
[Nexus 7 General] trssho91:
I've found charging from any AC source is fine. I did notice that some of my cheap USB wires don't identify themselves correctly. When I goto settings>battery it will say USB instead of AC.
[Nexus 7 General] Nate2:
I have not changed AC charger or USB cable (original ones that shipped with my N7). I am charging at the same location in my house, and I'm still using Android 4.1.2

My N7 used to fully charge in less than 3 hours. It is taking 8+ hours now.
[Nexus 7 General] trssho91:
Hmm... Are you stock 4.1.2 and have you tried to wipe battery stats?
[Nexus 7 General] Nate2:
My N7 is rooted, stock 4.1.2

I have not tried wiping battery stats.

I hope that does not cause more problems..
[Nexus 7 General] najaboy:
Don't waste your time. Wiping battery stats in no, way, shape, or form, accomplishes anything.... period. It has absolutely no correlation to battery charge or battery indication. Frankly, I'm a bit baffled as to why it was even seriously mentioned as a suggestion.
[Nexus 7 General] trssho91:
You are not correct, battery stats do not effect battery life. The only thing battery stats do is reporting. The reason it was suggested was that li batteries are not statically charged, and the charging circuit steps back as the battery approaches full. The is a off chance the device is not providing a full and correct current to the battery. Other than that, what's it going to hurt, no data lost and no time reloading apps since its not a reset. No need to troll if you have nothing to contribute to helping the op out.
[Nexus 7 General] lkspooky:
Samsung charger charges faster then stock

I am finding that my Samsung phone charger is charging faster then my Stock Chargers. I have 2 and they both drain faster then they charge.
[Nexus 7 General] najaboy:
Battery starts do not affect battery charge reporting. That fallacy of that was clearly and concisely debunked a year and a half ago. The one and only thing that the file being wiped has any relevancy to is reporting that "application x operated on battery for x:xx." As such, battery stats are wiped by the is whenever the device is unplugged after a full out near full charge. Nothing that's being wiped has any bearing whatsoever on charging or charge current.
[Nexus 7 General] trssho91:
Hmm, I am going to have to research that. Not to prove you wrong, but for my knowledge because that does contradict a lot of what I have read or learned over many years. If the battery stats do not help define the amperage curve, what does? There has to be some sort of adaptive charging circuity for lithium based batteries or they would all fry, overheat, or explode.
[Nexus 7 General] onejay09:
Battery stats have no impact on the battery level or charging operations, its basically just the info you see in settings/ battery usage, sorry guys
[Nexus 7 General] trssho91:
I knew it had no effect on charge level, that's what I meant by runtime. I simply implied that if the os thought the battery was higher than it was it would drop to a trickle charge too soon extending charge time. But anyway, whether I'm right or wrong let's not hijack this into another battery stats thread. There are too many of those already and the op still needs some help. Anyone wiser than me have and ideas.

Long story short my asus cable had a poor microsd connection if i barrely touch it... Will stop charging

My charging time changed from time to time from 3 hours to 6 then 12 hours.... So....

I bought a golden plated 75cm cable (short one) and its charging in under 3 hours. The microsd connection feel stronger, isnt moving or disconecting when touched.

Problem fixed for me.
[HTC One S] YawningAngel:
I have a friend with a One S that's stuck on version 1.78.206.4. She's rooted the phone and unlocked the bootloader, since which OTA updates haven't been applying properly (I'm assuming this is by design on HTC's part). What's the correct way to go about upgrading to JB? My current plan is to have her reset to stock, lock her bootloader, and accept OTAs until she reaches the most current ICS before manually applying the JB OTA, but she was a weird cid (O2___001) as a result of having a carrier-branded model (she uses it unlocked on 3, if that's salient) and I'm not sure if she can safely apply the OTA, as it's not in the list of cids that work in the thread (http://xdaforums.com/showthread.php?t=2063848). If she needs to be on the unbranded build, how can she achieve this?

Hey guys.

I'm looking for a faster way to transfer files from my PC to my GNex. MTP is way too slow (2.5 gigs is looking to take about 3 hours) and I don't have the patience.

Is there a good wifi transfer app to do this for me? I am not good with networking, so easy would be good. I bought "wifi file transfer" from the market and it works good for single files. I need something that will do my whole internal SD in a single shot.

Halp?

Hello guys, first of all i wanna thank u for your work, i'm a new user but i follow you by a really some times. Today i decided to install the 4.2.1 ROM on my nexus, i deleted all internal file in recovery mode but now when i connect the telephone on pc it doesn't work, maybe because the usb debugging is off and now i don't have any rom on my cellular phone. The problem is that i can't browse my telephone because my pc don't recognize it. i tryed to install some usb driver but nothing has worked then i can put in the now or old rom. how i can solved this problem? Thank u ( and sorry for my english )
[Samsung Galaxy Nexus] rudeguy:
To enable USB debugging, go to settings>about phone>tap on the build number 7 times. It will tell you "you are now a developer" and your will have USB debugging back

As far as your driver issues go, it sounds like you only installed fastboot drivers and not the regular drivers. Or somehow the regular drivers got deleted. If it was me, I would try rebooting my computer and phone. If that doesn't work, run the driver setup wizard in the Galaxy Nexus Toolkit. The first part of that process is deleting old drivers. It does a very thorough walkthrough on how to do that.
[Samsung Galaxy Nexus] NexusPsy:
Thanks for the answer, the problem is that i don't have any rom on my telephone atm then i can't go to settings ecc. is there a way to change the usb debugging in recovery mode?
[Samsung Galaxy Nexus] rudeguy:
so you are running stock 4.2.1?

Or...I guess I'm not understand what condition your phone is currently in.
[Samsung Galaxy Nexus] ahmadallica:
Try connecting your GNex to PC while in recovery mode then use ADB to push any ROM from PC to your /sdcard/ of your GNex in order to flash it.

At worst case, I think you can use a fastboot image to flash your GNex via fastboot.
[Samsung Galaxy Nexus] NexusPsy:
Now i running nothing, pratically i formatted all internal data because i would use the 4.2.1 version that is on my pc, after the format the computer does not recognize my cellular phone, so atm i don't have any rom on my phone and now i don't know how i can solve that, it could be easy if i can browse the phone on computer

As the title says, I got my Verizon Note II today but no LTE so far. I just took the SIM out of my Galaxy Nexus, which gets Verizon LTE in my home, and put it in my Note II (purchased for retail price without contract). Maybe the radio is just weaker in the Note II, but my Nexus always gets LTE in my home.

Do I need to contact Verizon to activate the phone or should I be able to just stick the SIM in there and have it work?
