When i turn off my g flex 2 and plug in the charger it turns on and boots up to android is this normal?
Yes
Okay. Thanks for the fast answer.
I have this phone now for a month or so and everything was good so far. But now it started to charge very slowly (i use included LG charger). It used to take 1 hour and a half to full charge, but now it takes 4 hours or more. What shoud I do? BTW the first time I plug in the charger it charges even slower (shows 10 hours till full charge), but after a few minutes I replug it again and its 4 hours then.
Beside a USB volt meter there is no indicator that tell that the phone charge at 5V or 9V. So it seems that you charger don't recognize the quickcharge phone everytime.
I have a usb volt meter and I noticed that usb cable quality is the second most important factor after the charger quality. Bad cable will result in high resistance and low intensity (and low power as you may know P=U*I)
At 9V, it's less sensitive to high resistance/low quality cable.

I was wondering if this is normal for the Raphael (I have a fuze) to charge VERY slowly..ive always charged via usb and read somewhere that usb does a trickle charge (i never knew this) so i tried an ac charger and still same thing..my kaiser (tilt) charged full in a few hours..this thing charges maybe half way in 2 or 3 hours...any ideas?
I have had my device plugged in (i.e. not USB) for a couple of hours now. The charge has gone up from about 30% to 88% and seems to have stopped there.
Usb charging takes much longer than charging via AC. My phone will go empty -> full battery in maybe 4 hours on AC power, and will not fully charge in 6 hours using usb.
Also, I have a setting where the screen doesnt turn off for 30 minutes when plugged in, plus much brighter. If this is the case and I am playing with the phone plugged in it takes even longer still (i.e. when I am charging at work).
dg252: It is possible that your battery may be charged, but the battery indicator is stuck. Let it charge till the LED stops pulsing, then soft reset.
I've found that the provided charger work very quickly, however standard mini-usb chargers or usb leads will take forever to fuly charge, if they do ever reach a full charge. I think I read somewhere that the provided charger works at a slightly higher ampage.
Hello. I bought a Moto G two weeks ago and I got a 5V - 1A(output) charger for it. It took about 2.5 - 3 hours to fully charge it. My charger broke and I bought another one today with an output of 700mA( at least this is what was written on it) and I noticed it was charging my phone very slow, about 3% per 10 min( 96% for 5 hours, if you calculate it). I brought it back to the seller for that reason(even though the seller insisted that it was better for the battery to be charged slow). What kind of charger should I buy? And how long should my phone take to charge(optimal time) ?
You can calculate this. Battery is 2070mAh, which means if you have 1A (1000mA) charger it should take about 2 hours. if you have 700mA charger it should be full in about 3 hours. That's in theory. In reality it takes a bit more due to efficiency of charging process.
With a 10v wall charger and Moto G default charging cable, 1h and 30 minutes maximum. This is for when the battery is at 0 percent.

And the phone still consumes energy if it is turned on, or being used during charging.

Does this still apply when charging from PC with original charging Motorola charging cable?
I charge mine in about an hour and 30/50 minutes.

Yes it does, because charging from pc only gives you 0.5 amps i.e if you're using a USB2.0
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

only one thing to your problem with charging, replace the new one usb cable and your problem will be solving

I know that but I was wondering if leaving it plugged in will it be bad for my battery at all
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.

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?
If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

Ok, I'll give that a shot. Thanks.
I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !
Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.
change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.
I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

How do you make full battery reset?
The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.
Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

I read somewhere that if you activate airplane mode the battery is charging faster.
Ok, so I have my Nexus 5 for about 8 months, but the charger that came with it doesn't work properly anymore.
Just after I got it, and few months later, the charger worked pretty well, and I also have a small amp meter that is connected into charger's usb port to measure Volts, amps and mAh, and when new, it pushed about 1.7 amps of current (it is rated to 1.8), and charged the phone in about hour and a half from 5% to 100%. Right now, the charger gives only 0.4-0.5 ams of current and charging time varies from 3 to 3.5 hours!
Has anyone experienced this problem?
Is an LG G2 (2.2amp) or G3 charger safe to use, as I tried G2 before and it charged the battery in less than an hour, without heating the device.
Also, I frequently leave my charger plugged in wall socket all day long, and it's plugged in without using more than it is plugged out (just when carrying it somewhere). Maybe that's why it degraded over time...
