Discharging while charging

Does anyone have issues where they are using their phone (just for simple tasks) and noticed your battery is draining significantly? Like right now, I'm typing and my battery just went down another percentage point while posing this.

charging off USB or the wall? USB or car chargers often can't keep up with the drain of LTE phones if you're using them at all.

I'm on AC right now. I have a power strip that sits at the foot of my bed that provides my devices juice.

At which battery level % did this occur?

I'd say if it happens between the 100% to 95% range, its normal, as I have seen that with other phones too.
If it happens at any other percentage, maybe you're charger adapter is not supplying enough power, but that should not be an issue with the stock charger that came in the box.

Have you checked that it's actually charging at AC rate ? I was surprised to find that the charger for my Palm Pre 2 was charging @ USB, I swapped the cable for the one for my TouchPad (same charger) and it changed to AC charging. I'll try different cable and charger combinations when I get time.

Install "Battery Monitor Widget" and monitor the charging rate under mA.

I use the plug that came with the phone a usb to the ac adaptor. I install the app will see tonight when i charge. Also an other point when i charge at night arround 10 pm 5% in the morning wake up at 6 am my phone is charge at 95 to 97% so not fully charge plug all night

It says it's charging USB, not AC.
What does Settings -> Battery say when plugged in, AC or USB ?

Ok for some reason the adaptor that came with the phone when I charge say usb but when I use same adaptor and an other usb cable a blackberry one its say AC. What the...?

Install BetterBattery to figure out what apps are being hung up (partial wakelocks) and re-install them. This drastically increased my battery life!
Also, the screen on wastes the most battery. Try dimming your brightness

Get a 1A charger.

Its the cable. Some USB cables have the data wires shorted or missing altogether and these USB cables are known as charging cables. All they can do is charge the phone. In AC mode. Bought a USB charging cable on amazon for 7 bucks now my car charger charges in AC mode.

I will work with no problems. I have done this many times as I forget my charger at a friends and use thier iPhone, WiMax, Bluetooth chargers.

I used to charge my WFS with philips mp3 charger.It works without any problem

I charge mine with my dad's LG Optimus One P500 charger if I forget mine.
If you have any of those phones, just twist the phone cable and put it in.
It works vice versa too.

USB is a standard voltage. You will be fine. There's essentially no difference between both the adapters you have.
Sent from my HTC Wildfire S A510e using XDA

USB is 5V and will carge fine anywhere from 500mA (standard computer USB port) to 2-3A (most wall and car chargers). I have only once seen a USB wall charger that violated this, it was 6V and came with a AA battery charger. you'll be fine with the ipad one.

I use a trust and ipod chrager, no problem since now!

any voltage up to 6V should be alright, the phone regulates it down to 5V automatically (though more heat is generated). the problems occur the other way where the charger doesn't have enough voltage (ex. my tablet requires 5.3V to charge normally, on 5.1 it takes a few days, and 5.0 it continues to drain the battery)

if you have 5v and 1Ah you can use it without any damge to battery if it's 1Ah+ it will charge your phone fatser but it will overheat phone. if it 1Ah- it will charge slow and after long using wont charge it till 100%

Chargers are so cheap on e-bay.... I usually get all my accessories there!

Q - why won't my one x charge with other USB cables

Hi
I have a few other normal micro USB cables and when I try to use them with the standard HTC plug, the phone shows its charging but the percentage never goes up. In fact it drains even though it says its charging. Why is this? I've tried two new cables with the official wall charger but I get the same. I really want to be able to use a longer cable.
Any ideas? If it helps I'm running Franco r11 kernel.

Not enough power coming from the power supply. Cable isn't the problem.

Well how can that be? I'm using the same HTC plug. It works with the white cable that came with the phone. But when a plug a different micro USB cable into it it doesn't.

I charge mine with a nokia cable which came with e7.no problem here.

all cables are the same, unless they are "charge only" cables (I got one like this for my Nvidia glasses)
it will not drain more than 500mA from USB. But the charging logic is acting weird sometimes so I think you just saw it glitching with other cable and not with the original one. It will drain with both if you use it in the meantime, try it.

Hmmm. I got the battery widget app which shows + mv when charged with the official HTC cable. When I plug in the other two miscellaneous cables the discharge rate is negative under the same conditions. Maybe its the kernel?

My phone currently charges with different USB cables.
I have a blackberry short cable (for when I'm at client sites) and I use my old SE cables to charge and even do file transfers..
Have you ran the charger test in the HTC Phone Diagnostics??

From my experience this phone is picky as hell when it comes to what charger it wants you to use. I ended up using the one it comes with. It charges the fastest.
Go to the play store and download battery monitor widget. Its really helpful! Shows you how fast it drains the temperature all in graphs.

My one x will not charge with a car charger for some reason. Even with original charger fine with usb from pc or mains charger.

I get the your phone is using more power than charge etc. Two cables from eBay and the same thing. Such a pain! I wanted a longer charger
Sent from my HTC One X using xda app-developers app

Its got nothing to do with the micro usb cables, there has been another power management update that was released last week, so HTC have told me, as mine sometimes doesnt charge more than 23%-29%, but when rebooted it goes to 63% and sometimes takes 12 hours for a simple charge, but was told it can take up to 4 weeks for the networks to distribute it. Im waiting for it too as my software is still on 1.28.771.9.
Im on 3 uk so it will probably never happen, but im currently in dispute with them because of faulty phone.

Hi I'm having the same problem with a longer USB cable.
I have a 3 meter cable from ebay which I've been using to charge my Desire HD for the past year without a problem.
When I tried this with my new One X it will not charge. The charge light is on but battery level decreases. I've left the phone sitting with the screen off for a while, but no charge.
When I tried it with the USB cable that came with the phone it charges fine, even whilst using the phone, with the same wall charger plug.
I've tried it with the wall charger plug that came with the One X and the one that came with the Desire HD, both same results:
Desire HD charges with both short USB and long USB cable.
One X will only charge with the short USB cable.
Is there a quality difference in the cables, or maybe a length restriction?
My One X is running Stock Android 4.0.3 (1.29.206.11)

I've just bought another 3 meter micro USB cable of higher quality, this one stated it would work with HTC One series phones. This cable charges my phone perfectly. The software on my phone hasn't changed from above.
Somehow it seems the One X, and maybe all other One series phones, are particularly sensitive to the type of USB cable? I didn't realise this could be an issue!

weird. i would have thought it was the increased resistance in the cable that was making it charge slower/drain
maybe its literally the quality of the cable, better materials, equals lesser resistance over a longer distance, therefore why the new cable will work and the other doesn't?

Cable

I'd like to buy a new and extra cable (not the charger) to connect my device to my computer and charge it then as well.
Apparently this kind of cable, micro data usb, seems to be universal. Is it really so as I don't want to damage it if I buy a generic cable.
Any help me would be great

I was also wondering this because I would like to buy a much longer cable since my power outlet is far from my bedside table.

The cables are universal, so any length would work for charging (data transfer not guaranteed).

Actually they are not that universal. While I dont have any technical specs there are quite large differences.
eg a PC USB slot will only deliver 500 mA UNLESS certain pins are connected that allows the connected device to tell the PC that it can take more than 500 mA. They will look the same but 1 cable will only deliver 500 mA & a different cable could deliver 1000 mA.
Another cable might be wired up for delivering power only from a USB slot or from the wall adapter, but at the same time not be able to do any data transfer.

To be sure I bought an Htc official cable.

You could always just buy a usb extender. That way you can use it for multiple things.

USB cables
Sorry to revive a dead thread, but there is some unclear info in here that I thought I could clear up:
Micro-USB cables are universal in the sense that they will all fit and to one degree or another charge your phone. The combination of the charger and the cable, however can yield wildly different charge rates. If you want fast charging:
1. Look at the small print on your wall charger and see what current level it will output. You're looking for something 1 amp or higher. Some chargers will say something like 500ma, which is 500 milliamps or half an amp, and that's slower.
2. Consider buying a special "charging" cable. These cables use the USB power that would normally be used for data to charge the battery faster, and thus they won't work as data cables when plugged into your computer. Here's an example of a charging cable from Amazon:
http://www.amazon.com/Mediabridge-U...1367955673&sr=8-2&keywords=usb+charging+cable
Basically what you want to look for on your One V is in the power settings for the phone it should say "Charging (AC)" when you plug it in and *not* "Charging (USB)". With the AC setting you know you're getting as much charging power as you can get.

I use my old Blackberry charge/USB cable with my One V without issue.

Yeah, I don't even use my HTC cable anymore. I originally stopped using it because I dropped my phone while it was plugged into it and it bent the connector. However, I HATED how short it was!! Then, I noticed that my Blackberry cable had the same end on it, and I've been using that for USB tethering, and I use my Samsung bluetooth earpiece charger to just charge my One V. lol
Oh, and I use the HTC USB to wall socket adapter to plug in my ecig. XD

I unintentionally bought some blackberry ones to have in my car, at my PC, at work, etc and they work great for me. I am just really careful about the wall adapter output because using my dad's tablet charger with micro usb killed my wife's optimus t.

[Q] Longer Cable = Less Voltage ?

OK, I was wondering...
I got a 2m cable for my hox, and it seems to work fine.
BUT the charging time is much longer with it!
Like 4.5-5h for full charge!! Why is that?
Does the extra meter looses power?

It depends on the type of charger.
If you look at battery stats does it say charging (AC) or Charging (USB)
Phone chargers have to have a couple of pins shorted out to charge at full speed

It's slower Compered to the Same Charger.
And it says AC too.

V=I*R where V is voltage, I is current and R is resistance. The charger will hold voltage constant at 5 V for USB.
A longer cable increases the resistance of the circuit. This reduces the current, and increases the charge time.

Ya, Thats what I thought
1. So what is the longest cable I can use without deceasing the current?
2. I tried a new charger that gives 5V 1.5A and it's even slower! (and the
phone says USB CHARGING, why is that?

Strange that a 1.5 A charger ended up slower.
I would say 1-2 meter cable is about the longest I would use for my USB chargers. For my tablet I use a 1 meter cable. Same for my phone (but it is not the same phone you have).

As i said previously about the shorted pins.
If they are not shorted then it will appear as USB charging.
Even though the charger can provide 1.5amps the phone is limiting the pull to 0.5amps because it thinks its pulling power via USB.

Any way I can Short those connectors myself?
cause I know the phone can take 1.5A from other chargers.

can anyone know when you charge the phone in less then 80% in will charge normally but beyond it, it wil slows the charging down...that will make charging longer...i check this and it only happen in HTC phone...
