I seem to get a longer battery life (first step down from 100%) if I charge my MDA C4 using the supplied charger as opposed to a charge from a PC using the USB lead.
If I charge using the charger, and just use 2G, I get approx 14 hours before the first drop in the batterymeter. From the PC it happens well before 11 hours.
Is this possible or am I just imagining things?

To get full capacity phone needs 5v 1000mA (= 1A) input, which is the charger outputs. If the PC USB output cannot pump that amount it might last shorter....
a PC's standard USB port only outputs 500mA (0.5A)
i think the supplied charger may be 2A (cant check atm), i know the official HTC Car Charger is 2A.

My original HTC charger (Model: TC P300) outputs 5v 1A
Interesting. I'll check the HTC charger when I get home.
However, Would this not mean that it would just take longer to charge the battery?
(Analagous to having to fill a bucket of water from a 1/2" bore pipe as opposed to a 1" bore pipe).

My original HTC charger is at 5V 2A.
What I did notice is that charging form USB takes much longer than charging off the wall.

It will do, should not effect the overall charge (as long as it is left long enough!)

Correct, actually water analogy is quite often used here
yes i thought that...
phone charge lasted longer with the mains charger than the usb on pc
and usb pc takes ages to charge full
So I guess we'll all be using our wall chargers now? As the charge is faster and some believe better!
Make no sense to me as to why the charge of the PCs USB cable is not as good as from the wall....
However the slow charge time bit of it makes sense
Car Charger
I have huge problem with my car charger. I use Noname USB car charger, that worked perfectly with my Trinity. Now, when i connect my Diamond it sometimes connects and disconnects the device to USB twice in two seconds and so if the battery is low message about battery fklashes in an out. SOmetimes it does not happen and the battery is charging normally. When i start IGO8 while battery is full and Diamond being charged, it sometimes LOOSES power and after couple of hours it gets out of power even when charged. Sometimes it doesnt happen and the device is charging properly, but very very slowly. When i turn device off, it charges normally. I tried two different chargers and get the same results. But none was HTC original.
It's irrelevent how the phone was charged. If the battery is full, then its full ,and it will last the same period of time irrespective of how it was charged.
Charging rates will vary depending on input current, but once the touch sensor light stays on, then the battery is full.
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.

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.
Sent from my GT-N7000
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.
Andrew
I'll give that a try, thanks
Some kernels come with USB fast charging as an option that you can toggle. If you use this, does it shorten the battery health long-term ? I'm not referring to turbo chargers (aftermarket), this is just the kernel setting. I recall reading this awhile ago, but I was curious myself.

all it does is increase the voltage coming in when charging via a USB. USB charging voltage is about a quarter/third that of a wall charger. no, no negative affects.
Not at all, even with USB fast charge on it will draw less power than if it were plugged in a regular wall charger or the turbo charger. There's an app called Ampere you can use to monitor how much power the phone draws while charging (or even discharging) you can use it to see the differences between regular usb, fast charge usb, turbo charge, etc.
Ok, that's good to know. Now I can re-toggle the feature and not worry.:good:
What about if it is toggled on and you put it on a regular charger ? Is it still fine ?

Motorola put in support for the Qualcomm rapid charge in the nexus 6.
Read up:
https://www.qualcomm.com/products/snapdragon/quick-charge
It allows the battery to charge at a higher voltage with USB connections and Qualcomm certified rapid chargers AND a compatible cable. The nexus 6 can still recharge with standard chargers and cables, just at a slower rate regardless of kernel support.
To answer the damage questions: Moto says no damage to the battery as long as certified chargers are used.
Can't you use any standard usb charging cable? (Assuming it's not really long or poor quality)
Hi everyone, so my issue I currently have with my Nexus 6 is as follows:
Device Details: Nexus 6, rooted, running CM13, Xposed Framework installed
Charging from USB: shows "charging slowly" message on lockscreen. Ampere shows an average of about 200mA, regardless of type of charger. Tried several QuickCharger adapters and a regular adapter, as well as several different cables to the same result. When connecting to a PC via USB, it shows the same charging power, however my laptop is not recognizing that the device has been plugged in.
Charging Wirelessly: charges normal as it always had, showing a average of about 500-700mA.
The issue occurred suddenly while I was out hiking and attempting to charge via a QuickCharge capable portable battery. The previous day it was charging as it always has.
All signs point to a damaged micro USB port on my Nexus 6, but wondering if there could be any other possible causes. I'm hesitant to try a factory reset to troubleshoot it as a software issue since I have no way of connecting it to my PC to re-root and re-flash CM if that doesn't fix the issue.
If it is the micro USB port as I think, any suggestions on how to remedy this? I'm used to using my device heavily everyday and charging it with a QuickCharger as needed, so this slow charging is a significant issue right now.
Thanks for any help!
your phone charges at differing speeds at differing parts of its charging cycle. and on top of that, charging via usb instead of wall charger will carge your phone at a much slower rate. that said, we also have a "usb fastcharge" option included in many kernels/custom roms. but you also have to know that fastcharge doesnt work with every usb port that you can plug into. it only will work with certain usb ports.

Sorry, I should have been more clear. When I said "Charging via USB" I just mean through the phone's microUSB port. Regardless of whether it was plugged into a wall charger(with or without QuickCharge 2.0) or my laptop or a portable battery, or a QuickCharge car charger, I was getting the same charge rate and message showing "charging slowly", much slower than wireless charge rate which showed the normal "charging" message. The Qualcomm QuickCharge 2.0 using the provided Motorola Supercharger or my QuickCharge 2.0 capable portable battery has always worked great prior to this issue.

ok, because the included "fastcharge" is only for usb charging. but regular charging still depends on where in the charging cycle you were. for example, at 92 itll charge at a much slower rate than at 50. what battery percent where you at when you noticed?

Initially very low, under 15%. Was attempting to charge with a QC2.0 portable battery, but the device was draining quicker than it was charging. When I got home, I attempted the Motorola "Turbocharger" wall charger and got the same rate. So I put it on the wireless charger, and as it charged, I kept testing the wall charger every 20% or so, getting the same slow charge rate.
The bottom line is really that the Wireless Qi charging is functioning properly as it always has, but any "plugged-in" type charging is charging at an extremely slow rate, no matter what type of charger, no matter what % the battery is at.

odd! it could be a software issue or just a derp. have you tried rebooting? im one of the few that i know with a broken usb on my n6. and it charges slower. it used to charge at about 2400mV, now it charges at 800mV max. now that its completely broken, i cant charge it via a usb anymore, now i charge it wirelessly, which is at about 800mV max as well. anyways, try a reboot, or reflashing your software first, before doing anything extreme.

Yea I've tried rebooting like 20 times lol. Also tried doing a CM nightly software update. I'll see if reflashing will do the trick. Any suggestion on reflashing from the device? I've always used Nexus Root Toolkit and did it from my PC.
If that doesn't work, guess I'm stuck with wireless charging too. Thanks for your help!

I've been having a repeatable problem. I have a Note 9 that will charge faster when I disable fast charging under battery settings. I tested the load being drawn with a USB Power meter these are the results I got.
Using a USB-A to USB-C cable:
When QC is enabled:
Phone draws 0.5amp charge, 10ohms resistance at 5.02V.
When QC is disabled:
Phone draws 1.2 amps, 3.9 ohms resistance, at 5.02V
I am using the same cable, same power bank. The power bank's USB-A port is able to draw ~1.9 amps at 5V, tested using a USB Meter and Load Tester that will put the USB under 1 amp and 2 amp loads at 5V, with resistance being ~2.7 ohms without the power bank turning off. I haven't tested the power bank at 9V, I don't have a 9V load tester
When I immediately switch from QC to non QC, the results above are repeatable.
Things I Have Done So Far:
Reboot Phone
Clear Phone Cache
Reboot Into Safe Mode
Try Different Charging Cables, Blocks, including OEM parts.
Every once in a while, it will switch back to being able to QC fast charge but it is random.
If I use a Power delivery capable block charger, it will charge at ~2750mA (I dont have other numbers like amps, voltage, or resistance, I'm still waiting on a USB-C meter)
My phone's wireless charging has no problem operating at it's max capacity
Any one else have this problem? Anything else I could do before I factory reset my phone?
I posted about losing Fast Charge thru the stock cable a while back and got no answers or a fix. I have not tried turning off the option to see if it charges any faster. It takes almost 2 to 3hrs to fully charge at this point. I'll take any fix or work around at this point.

Turning off fast charge made my charging a bit better. With Fast Charge (FC) turned on, I was getting 0.5amps (gave around 400-500mA). Turning FC off, sped up my charging by 50%, charging at 1.2 amp (roughly gave me 800-1000mA; Both charges were at 5V). Im able to charge at around 1000 mA with this setup, a little less than wireless quick charge. No idea why turning it off helped.
Another workaround that brought my charging speed WAY UP, to 2500mA, was buying a Power Delivery (PD) capable block WITH A USB-C to USB-C cable. I can get normal fast charging speeds with that setup.
I cant get FC with USB-A to USB-C cables, which is frustrating as most of my charging blocks are the regular USB-A input port.
Hope this helps you. 2-3 hour charge is brutal.
What's even weirder is in my car my phone would barely charge. But since I lost FC at home, it started working in the car. So in my car I can FC but not at home. I even tried the wire I use in the car and still nothing. Idk what is going on
Is it possible that turning off QC is turning off a regulation in the software to keep the battery from overheating? With this regulation turned off that would normally be on when quickcharging, the regulation is not active, thus causing the battery to charge at a less regulated speed, causing charging to be faster? Maybe there's a QC bug currently that's hampering it's full potential? What software version are you guys currently?
I just checked QC on mine on the latest Xfinity version and no matter what charger or cable I use with the function, it is working.
It's def not a software thing. I'm on latest October patch. Samsung told me that they have seen some issue with the charging port and once it goes bad there is nothing to do but replace it. They told me to bring it in to a store for repair thru my carrier. Haven't had a chance to go.

That what I was thinking. Something is actively limiting the charge coming in. Everytime I had quick charge enabled I've been monitoring the ohms and the resistance would automatically jump to 10ohms. Then I disable QC and the resistance automatically drops to around 6 ohms.
I'm running Android Pie 9.0, Kernel version 4.9.112

Yeah it could definitely be hardware related as well, due to each pin on a type c charging serving different purposes. There are two specific pins(I think it's two), that are responsible for enabling higher input of electricity. Couple years ago Google made comments about the cheap Amazon knock off cables and why they failed after a short while. Wouldn't surprise me if Samsung cheaped up for the cables and port on the device. I'll have to try and find the articles I read concerning the pins.
Here's a good start to understanding Type C.
https://www.allaboutcircuits.com/te...pe-c-which-pins-power-delivery-data-transfer/
Its the **** cable they supply with the phone.
I had all the same problems.
I noticed that when I turn off quick charge the phone can charge at 5v 1.7 amps. (USB doctor).
When I turn on quick charge it can only charge at 5 volts 0.40 amps.
The phone is trying to charge at 9 volts but for some reason cant so it goes into this safe mode.
I purchased a new Samsung cable it lasted for a week and developed the same problem.
A hint when it develops this problem Dex stops working.
I tried all kinds of cables. One Plus 5, and a few others. I finally got it to work again with my wifes one plus 6 cable.
Im now researching USB Type C ports and USB standard 2, 3, 3.1, 3.2
As well the quick charge tech used by Samsung. Its not Quick Charge 2. Its a proprietary standard.
So if your having problems with quick charge it could be due to your cable or your Port. Things very rarely go wrong with the charger. Also get yourself a USB Doctor. Its a big help. And only costs a few bucks.
Hope this helps somebody out there.
Right now I am trying to compare Note 9 vs Note 20 USB cable.
