Does mi5 really have autocut charging when charging overnight?
I dont think so
Sent from my MI 5 using XDA-Developers mobile app
Not really a cut to 0 A, but the current becomes so low that it's safe to be left charged. Checked by USB doctor (0.1-0.3 A only when you left charged at 100%).
I use a long cable so it takes longer to charge
Why does this matter again? It's not like it's using NiCd that is exposed to memory effect.
I have a 3rd party USB Type-C-to-Type-A cable with metal USB head which is slightly warm to the touch when charging, but when it got to 100%, it's not as warm.

Hi,
I have a new and flawless Note, the USB connector is OK.
At night I connect the Note to the charger and I put some music on to fall asleep. Playback is configured to just play one album once.
Normally I put the phone in Flight Mode, in order to sleep without unnecessary radiation next to me.
On some few occations (it happend to me for like 5 times now), in the morning, the phone is not charged at all! But I am 100% sure that the battery status icon on the top bar signaled the charging mode.
This morning it happend again and I noticed that I left the Flight Mode off (because my wife is away and I want to stay in contact if needed).
Also, I noticed that I have been using a ZTE charger specked with 750mA, while the original Samsung Galaxy Note charger is rated 1000mA.
Can it be, that I was using the ZTE charger on its limit and that having apps running, or maintaining flight mode off, was enough to actually not being able to deliver that extra juice to charge the battery?
The other reason could perhaps be a software problem, like some app draining the battery as much as the charger is able to charge, so in the end the battery stays more or less the same.
I am positive that the USB port is not broken. I.E. I tested by unplugging and plugging the charger from the wall socket instead from the phone and all is recognized OK. Also, no issues when connecting to the PC.
What is odd: on previous occations I think I remember that I just plugged the phone back and it charged.
I swapped the chargers, but still I have this odd impression, fearing that the device might have an issue.
Anyone had similar problems?
Cheers,
vma
Yes, looks like a weak USB charge problem. You get similar behaviour if you try to charge the device from a PC - sometimes I have mine plugged in to my PC at work all day and it barely charges. Get home, put the official charger from Samsung in from a walk socket and it charges in an hour or two max.

Hi, I've been using a note for about a month and a half now, and all has been well.
Until about two weeks ago, when my phone started charging very slowly via USB. Using a 2.1amp charger, it takes about 4-6 hours to charge, and about 7-8 hours using a 1.1amp USB charger. The less said about 0.5 amp chargers the better!
However, when I'm charging using a 1.1amp charger (Standard USB output), often when at 15 or less percent of the battery, if I still use the phone while plugged in, it actually drains power faster than the USB port can provide it! It will often shut itself down and give me a "extreme low battery" screen, meaning I can't turn it back on until it has some charge in it... which can take up to 20 minutes via the same USB port/wall adaptor
Running stock 2.3.6, unrooted.
You could have a faulty or dirty micro-usb port or a faulty battery.

I have the same problem. My Note is new and I don't think the battery is faulty
With stock ICS in comparison to GB, it consumes more juice thus takes longer time recharging.
This is normal, but sad.

Same here
I have the exactly same problem and ended up here, while searching on google if there are othere with similar observations. I can as well comfirm that during playing certain games the phone looses charger faster than it can be recharged.
Beside that my phone overally looses battery much faster than it used to be.
I found out that you can recharge the phone considerably faster when it is completely turned off.
[edit:] The problem started after the update to Android 4.0.
Now I have no way out but to root my SGN running stock ICS that allows me to do more customization.
I am using SetCPU to limit CPU clock at 1200 MHz (from 1400 max). Only certain apps really requiring CPU power, I specifically allow them to run at max MHz.
This helps reducing recharging time a lot...a lot (even much faster than charging when on GB) and allows more time in outdoor uses. And there is no lag.

I've found the total opposite, I find charging in ICS (Stock not a custom as I've not tried one) to be loads faster at charging than in Gingerbread.
What programs do you have constantly running? The more that's running, the more juice it's gonna use and therefore the slower the charging will be.
How long does it take to charge with the phone off?

Same problem with charging as well.I an using ics 4.0.3 cpw version and it draws more than it gets from the usb charger.
I also experienced slow charging before.
What I do is to close all the applications and see if that works.
Same thing happened wid me... Its Kernel fault.. Try changing kernel.. It will help
Noted by the BEAST!!
Look for runaway tasks consuming high CPU and maxing out the CPU clock rate. You can use a CPU monitor like System Panel Lite, and also simply feel the phone at the rear near the camera. If it is hot you have a problem of some process going nuts.
This is a classic problem I've faced on ICS and I've given up with it and gone back to GB. No problems since.

Just to clarify, a standard USB port on a pc/laptop can only provide 500mA not 1.1amp. Not sure where you got this value from. Therefore it will not provide anywhere near the required current, especially if you are actively using the phone. Most cheapo car chargers are also innadequate at 500mA. The standard sumsung wall charger only provides 1000mA.
What 2.1Amp charger are you using? Its not recommended to use more than the standard samsung charger outputs !
You need 1000 mA (1 A) charger for proper recharge even on GB.

1A is the standard Samsung charger.
So is it okay to force the note to use the 1 A ? standard it is set on 700mA
You can adjust the charging control with Voltage Control
I too started having this problem yesterday after updating to a recent version of Visual Voicemail Plus. Even charging from the wall outlet could barely keep up. Turns out the problem was VVMP continually polling NON-STOP for voicemail. Reverted back to older version and problem ceased immediately.
My point....your problem might be software and not hardware. I'm still on rooted and overclocked GB with franco.kernel.

data cable will charge slower via usb port.
I'm using non-data cable to charge via usb port, it's way faster. Only cons is that u won't be able to transfer any data.

I have been using HTC & Samsung wall chargers, Belkin 1A in car. All chargers provide fast recharge. However, the quality & length of USB cables are crucial.

Just to clarify things, the 2.1amp charger is a USB battery pack, and the 1.1 amp charger is a USB wall adaptor. I'm running 2.3.6 GINGERBREAD, unrooted.
There are two charging rates, slow via the USB data cable, and faster via the charger (where the D- and D+ pins of the USB are shorted). If it thinks that you are using a computer USB when you are in fact using a charger, your charging will be at the lower rate.
I had this problem of slow charging and the cause was a dirty connector, get some electronic connection cleaner from an electronics store and spray the USB connection and cables - that fixed my slow charging problem.

I'll give that a try, thanks
Hey I was wondering if something is wrong with my device.
I am encountering weird things regarding recharging the device in reliability charging up.
So i am using the original charger which came with the phone, the phone is just like 3 month old i didnt notice anything like that earlier.
So when i am charging the device, sometimes it stops charging, Today I encountered it charging to like 56% and afterwards no more charging so when i got up, my phone was 14% left even when plugged in.
I encountered it several times recently that it stuck recharging at around 50-ish or 70-ish %.
charging usually takes up reasonably long. About 10% an hour. In Settings -> Battery it sometimes it displays USB even when it's charging via AC.
I am not running any fancy apps which drain the phone or clock cpu.
I am running 4.1.2 I9305XXBLL3 Rooted.
Anyone have any suggestion?

Samsung charger that come with the box really charge slow because it only supplies 1Amp.
But for your case seems different. Before checking the software side... have you checked if it's the charger or the cable itself has the problem? Try using other charger.
do you think a nexus 7 charger works fine w/o doing any (more) damage?
Many times it's because of dust and dirt collecting inside usb port. Clean it with compressed air or small brush and try again.

i am aware that dirt might be the problem, but i've took my torch and put some light into the dark usb port to see if there's any dirt but everything looked quite clean to me. I don't have compressed air with me atm do you think a manual air blower used to clean dslr sensors can also do the job?
any other suggestions if the charger and usb port ( dirty ) is not the case?
Use toothbrush and tiny bit of alcohol ( can be after shave) on it to clean port. Do it when phone it's switched off. It's worth to try.
Did you try different charger?? This can be main problem. Many faulty chargers this days.....

i have been trying out the nexus 7 charger. it seems to be a bit faster but not as fast as i am used to be on galaxy s2 ... i used the air blower and a tiny bit of dust came out but not quite much, i will see how it performs.

Check the output voltage if same, a bit higher ampere would be fine just not too high, and not voltage.

Samsung charger provides 1000mah because that's the stock charging setting for the SGS3. You'd only need a different charger, like a N7 one if you change the settings to above 1000mah.
OP use current widget to see what current your phone is charging at. It should be 999mah from the wall charger, then you can change chargers and see whether it's the charger or your phone with the problem.

It's what I said
So... Yesterday my battery decided to drain really fast. Checked the mA and it was -1137 and when I plug in my charger it decreases still to-500 or more than -2000. When im not using my phone the phone will charge about 5% per hour and stops charging at times. Leave it over noght and it might charge 10%. Same gies for when the phone is turned off and charging. So, is it the usb port or the battery.
The battery drains real fast. The port is clean and the board looks fine when i dissassemble. Usb cable holds tight, when i pull the connector part up then it disconnects.Used multipll cables, sockets, and chargers.
Is it my battery or the port?

I've just posted my solutions to some very similar problems you've described. Not able to to post links but it should be easy to find, just search for [solution]usb port / charging issues.
Have you checked the two copper plates on the under side of the removable plastic unit just above the usb socket. Adjust / manipulating the connection there has solved my charging problems.
Hope this helps. I'm not an expert by a long shot, but if this is not the case, and you have replaced / renewed everything, then I at very least would recommend trying a new battery.

Hi,
My wife's S5 mini seems to have developed a nasty habit of not even fully charging overnight.
When using a USB powermeter, I see the current fluctuating between (roughly) 200 and 800mA. Other devices on the same multiport USB charger have no such issues, so it is not the charger.
When using the OEM charger and lead it will also charge very slow, to the point where it may not even be full the next morning.
I downloaded the Galaxy charging app (very informative on my S4), but it always shows 1mA chargingcurrent, so I assume it does not work on the S5 mini.
I cleaned the USB-port on the phone and removed some lint, but no difference.
Wiggling the micro-USB-plug makes no difference, nor do different charging cables.
We switched the phone OFF and removed and reseated the battery: the problem persists.
What I did NOT yet do is swap the battery (we have two same-age S5 mini's in the house and only one has the issue). If I can pry the second one from my daughters hands, I will try this and report back. Obviously if the problem moves with the battery, it is the battery. If not, it's the phone. Or if the problem is gone, then it is just those darn Gremlins again.
What I also did not do is boot into safe mode (or whatever is sometimes adviced) as the phone does not go through its battery fasst, it just charges very slow. An inefficient app would also not explain the fluctuating currentdraw (certainly not it dropping below 500mA when battery is 80% empty), so atm I don't consider an app to be a likely culprit.
Any ideas are welcomed.
Ideas:
1. Install and use the free app Ampere to check both cable and charger;
2. Turn phone off and plug in charger, even off it shows the percent charged, so you can check if it's system software problem or not.
Check if the micro usb port is dirty. You can't imagine how much dirt can get there, specially fibers from clothes. Normally I use a needle to clean it, maybe there is something more appropiate.
Got the same problem after 3months use.
To avoid this problem:
1- Plug the charger
2- After 5 seconds connect micro-usb into the phone
If you connect first the phone to the charger it will not charge properly
