If battery is charged to 95% and i turn on 85% protection, and cable from charger is still connected - battery percentage do not drop down, and there is no loading indicator either. Is smartphone using only energy from charger bypassing battery?
?
Hi, my understanding is that the phone always use the battery, but I may be wrong. It's an interesting question. Did you wait enough time to confirm that battery wasn't dropping, in this condition?

Yes, no dropping, and no indicator that it is loading.
On menu diagnose phone said that charger cable is not connected.
(when turned on 85% prot after above 85)
Do this: when your battery is below 85% go to settings battery diagnose and check charging through cable.
Status will be normal.
Now disable 85% prot.
Charge to 88%.
Do not disconnect charging cable.
Enable 85% prot.
Battery status indicator will still look as not charging.
Again go to settings battery diagnose and check charging through cable.
You will see that it is not charging, but battery % will also not drop anymore when cable is connected.

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.
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.

did u try a different charger?
Hello! I need a little help finding an app or a tweak if any exists.
I have samsung galaxy tab(GT-P3110), the charging port is totally destroyed, so now the only way to charge the battery is to directly charge it. I opened the back of the device and extended two wires (+) and (-) from the battery socket and then put back the cover. So now I charge the device by connecting those two wires sticking out of the device with the stripped end of a usb cable.
I know this way of charging is damaging the battery or inappropriate, but atleast i'm able to use the device than just uselessly throwing it away.
When i use the device, there is no real way to say how much charge is remaining. Even if the device is charging, the device shows that the charge is decreasing like as if it wasn't charging but it is. and once i reboot, it shows the real increased charge %.
So i wanna know, is there anything i can do to get real battery stats while the tablet is still on?
Hello,
I have had this tabled for a while and it was always charging extremely slowly but I never took it out of the house so it wasn't a bid deal for me. However I have given it to my mother and she uses it in other ways. Anyways, the note 10.1 is the slowest charging device I have ever seen. It takes probably 48h-72h to charge it completely. I am using the original cable and power brick, I have tried ALL the outlets in my house, I have tried using the computer, I have tried using another cable (probably like 5 different ones) and other bricks (from iPads, my note 5, etc) and nothing is working. I have seen other posts regarding slow charging but none of them solve my problem.
Thank you
Thats is not normal .
I would factory reset and flash a stock rom .
Swap battery or take to a service centre .

"probably"?
You can't troubleshoot perceptions and guesses. How long does it actually take--repeatably--to charge from what percentage to what percentage? (i.e. "Went to bed, battery was at 40%, charged overnight for 7 hours and battery was at 60%.")
There are apps to check charging current (Ampere being one of them).
The fastest charge you can get is with the OEM charger in an outlet, not a PC.
Understand that this is a 7,000mAh battery without any quick charging applied to it.
Additionally, if you are using the device whilst charging it, you aren't really charging it since the drain is about the same as the charge; you'll effectively neither charge nor discharge.
Finally, check for battery-draining apps; you might not have a charging problem but an app-drain problem.

The time varies, but it is between 2 and 3 days to charge from 0, never less.
I do use the OEM charger and cable and an outlet.
I do understand that but 2 days seems a bit of a stretch, don't you think?
I am definitely not using it while charging, because it's impossible. It just doesn't charge fast enough to be able to use it. It drains quicker than it charges.
I highly doubt that, I only have YouTube and Chrome installed on it.
Above 6 hours with stock rom and charger is abnormal .
Usual replies .
One cable
Two charger
Three battery or connections .
Four USB port
Five motherboard .

Yeah, 2 days isn't right. It also shouldn't be discharging faster than charging, especially with the OEM charger.
I leave mine plugged into my PC (only 500mA max current) with the screen on (about medium brightness, mostly black screen, which is most power-friendly for OLED) using LectureNotes all day and it will neither charge nor discharge (technically, it's charging at the same rate it is discharging); the percentage doesn't move.
What does Ampere report?
Do you have another charger you could try? any 5V and at least 2A would work.
Also, ensure your cable isn't intermittently open (a break in the cable, temporarily disconnecting the charger).
If the cable and charger are good, then the battery would be the next likely culprit, followed by the charging circuit.
Finally, ensure heat isn't an issue (is it in a case? remove it).
Mine was messed up but I concluded it was the port and cable. I got a new cable and then replaced the charging port and viola. Charge time went from 8 hours back to the usual 3-4
