Hello,
my nexus 5 after 4.4.3 discharge faster than charges when its connected to usb and i do nothing, only texting sms messages and turned on wifi. I mean, when its connected to usb my phone discharges. Also, i left turned on wifi through the all night and my phone within 9 hours charged from 10% to 65%!!! What's the problem?
USB charging is limited to only 500mA. At any second your phone may be using 200-1000mA and might not receive enough juice to charge. Best case scenario is a slow charge.

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.
I got a Nexus S the other day and so far impressed apart from one thing. I left the phone on charge overnight and in the morning it said it was only 96% charged. This was with it plugged into the mains charger for almost 8 hours with the phone on stand-by.
So I read on a thread somewhere you need to discharge the battery fully, then charge the phone with it turned off to correct this. So I did that last night and again this morning it says it's only 96% charged.
I'm also disappointed at how slowly it charges via the USB cable. Had it plugged in for a couple hours at work on my computer and it only went up by around 3%, this is shocking. I'm trying it again now on a different computer and so far it's only gone up 1% in an hour.
What is going on?
It's meant to stop at 95% - 96%
Leaving your battery at high voltage (100%) will cost the battery lifespan to shorten in the long run. So usually chargers do not charge it to 100% at all but slightly below it to lengthen battery life.
OK thanks for your quick response.
Regarding it being slow to charge connected to a computer, is that normal?
Are you leaving your screen on while charging? Because the screen eat alot of power, so that might be the case.

Nope, it turns off after 30 seconds. Wifi was also turned off.
Maybe try using SetCPU to alter your processor speed during charging and screen off to the lowest. It will significantly increase your charging speed.

I will give that a go. But really should this be something that I have to do, shouldn't the phone charge on it's default settings via USB at a decent rate?
It might be due to programs running at the background. I'm not sure. But my Nexus S charges fast enough though. Not as slow as you mention. Maybe try doing a charge after a reboot of your phone? If it charges faster after the reboot, it is most likely the background processes you had.

Yes it is. USB only supplies 500mA. Plugging into the wall is usually 700mA or 1A. Have you ever seen how long it takes to charge an iPad on USB? Its wall charger is 2A.

No because usb is only half power of regular wall charger, so it takes much longer to charge on usb. It's possible when using the phone during usb charging to pull more power than usb can provide, stopping the charge completely.

I also have this problems, but if don't use the computer usb to charge, it seems no problem.
Ive been using my s3 for about 40 minutes on CM10. Plugged into a dual usb charger connected to not ip port, which in the past i have used fine. I have lost 5% battery in this time. Current widget doesn't work yet with S3. Suggestions?
Edit - The first time I got the phone after a full charge and discharge, while plugged into stock charger and before anything root, the same problem happened.

From what I heard, the charger can't charge the phone fast enough when you are using it thus the losing charge while plugging in. If you are talking about losing percentage right after you disconnect the phone from the charger, that is a feature, I do not know at the top of my head why it does it.
If charging through USB port (and many car chargers) you're capped at 500mA vs 700+ for wall chargers. You can install a kernel that supports fast charging and you will get 700mA through USB.

I'm having the same issue whether charging from usb or a power outlet. Charges for a bit initially, then drains. Happens with different cords, too. I'll pick it up and it will feel warm, see that the battery is lower than when I plugged it in, then put it down. Then it cools off and starts charging again. Any ideas?
Same here except
i have the same issue, i had stock Touchwiz and suddenly the phone started to discharge while on charging outlet, tried different chargers, outlets, different ports, etc. still wouldnt work, i even deleted several applications and turned off several phone functions, etc. still nothing, then i rooted to CM10.1 and the same issue still presists, the phone charges a bit then discharges weather i use it or not. the only solution to charge it, it seems to be by turning off the phone. i think it has to do with the usb port on the phone as i even had the battery changed and it still would discharge while on a charger.

Hello,
When I charge my Nexus 5, the battery icon keeps on showing it is charging even so the battery is at 100%. Also my USB charger (not the one LG one) indicates that the device is still charging. Is this normal ? Would this damage the battery ?
Thanks
It's normal.

Thanks ! (But i just find this weird as I expected a device to stop at 100%)
I understand what you're saying but it's not a charging icon, it's a connected to power icon. If you were to use something like the dashclock extension it would show that it actually stopped charging once it reached 100%
Thanks for the reply.
The thing is that I have this charger http://www.portablepowersupplies.co.uk/portapow-quad-usb-mains-charger/) and the LED indicates charging (albeit I did not measure the current ).
Nice unit!
Are you connected to WiFi while charging? I had the really bad battery drain issue while connected to WiFi after the 4.4.2 update. I lost about 30% of charge after 4ish hours while connected. Currently I'm at 92% after 3 hours.
The WiFi battery drain could be causing your phone to not fully charge or at the very least make your charger THINK it's not fully charged. No harm should come of it either way but it's always best to pull your phone off the charger once it gets to 99-100%
Thanks for the reply. I had Wifi activated; it might be the reason.
My wireless charger LED didn't shut off when my N5 was charged in a powered off state. Usually it does once the battery is full.
That said, I don't think it's over-charging the battery, as that would be really bad

Don't worry about it. This isn't the 2000s where constant charging is an issue.
Just tried with the Wifi Off. My USB charger then indicates that the unit is not charging.
Thanks for the replies and great help.
Don't worry about it. The charger isn't the thing that determines how charging is handled, it's all done on the phone side. The phone knows how to take and stop taking power.
In the case of the Nexus 5, it most-likely stops charging the battery but continues using the power from the charger to actually power the unit (thereby no-longer using the battery to run the device, but not charging it any longer).
Hello.
I have a new Moto g 4g and sometimes when I plug it into the mains to charge the charging battery icon appears and the phone says charging on the lock screen. But as soon as the % number should go up (i.e. after a couple of mins on charge), the battery charge icon is still there but the phone no longer says charging on the lock screen, and it doesn't charge no matter how long it is plugged in for (although the battery doesnt drain either).
I turned the phone off and plugged it in and when it got to the charge screen it kept flicking between a question mark, and the percentage charged amount.
It seems to always charge fine when I plug it into a USB on my computer (although slowly).
Has anyone else seen this? Is it worth completly draining the battery and charging from flat, or would this do more harm than good?
Thanks for the help.
