Can anyone confirm whether their wireless charger behaves like the wired chargers, and "stops" charging after the LG G6 reaches 100% battery charge?
I'm concerned that wireless charging might harm battery longevity, because the wireless charger seems to continue charging after the phone has already reached 100% charge?
I checked this by using a watt meter to monitor power consumption of the wireless charger as follows:
* No phone placed on the charger = 0 watts
* During charging below 100% (phone is powered on) = around 10 watts
* After 100% (phone is powered on) = approx. 4 watts
Note: The phone automatically powers on if you place it on the wireless charger, so it's not possible to wirelessly charge with the phone turned off.
So it seems that the wireless charger will continuously apply ~4 watts to the phone after it reaches 100% charge. Won't that be a problem over time, especially if you use the wireless charger overnight?
No, it does not continue to charge. It draws some current because it continues to maintain a connection with the phone. Otherwise that little blue or red light would go off and you wouldn't know if the connection is working or not.

so, here's the problem -
i got HTC sfift, as a gift, and it was used sometime. second time I recharged it - it fails.
as soon as i take out power cable - it goes dead. ok, maybe a second, but it shuts down.
when i load vista, and go in battery info - it says - 1% and charging. and it stays on 1% all the time.
i'm asuming it is faulty battery, but could it be something else ? maybe a power socket ? or maybe those small metal pins beneath the battery, that touch battery and the backside of the shift .. ?
anyone ?
it's the battery. Mine charges up to 50-60% and stays there and the max is slowly decreasing downward ...
My shift can't charge or power up off AC
Hi, I have 2 shifts, and one of them is being funny (and not the funny "ha ha" kind)
The Shift X9500 will not charge off of AC power.
I have done these tests & got these results:
- Battery in & AC plugged in = no charge light comes on & W7 says nothing about charging
- Battery out & AC in = no charge light & W7 says no battery (expected)
- Battery in & AC out = no charge light & W7 says not charging (expected)
I tested AC adapter on a Tekkeon external battery and it charges that external battery so the AC cord works.
A new test was done.
With battery out, and AC cord in, the unit will not turn on
With battery in (and some voltage on battery), and the AC cord in, the unit can turn on, and I can remove the battery (while still on) and the unit remains on, and the battery area says (No battery-AC Power)
So what would make the Shift not turn on with the AC cord in only?
And, what would make the AC cord not charge the battery?
I'm thinking it is related to a fuse/circut protector or something from the AC to the unit, but mostly, why can the Shift "Run on AC, but not turn on with AC only (i.e. requires a battery to turn on)
UPDATE:
I called HTC and the Shift is under warranty so they said to mail it in.
It seems that the issue is mostly eluding to the AC not charging the Battery is causing all the other issues...we will see!
I have a simple Qi power mat that I use for charging my Nexus 4 overnight. It works quite well - a little too well in fact as it charges to full with about 6 hours left of the night. It then "disconnects" from the wireless charger and begins to discharge as if it were just sitting not on a charger.
If my backup is running or some other background tasks occur I end up with only 80% battery left in the morning which is annoying.
The way to restart charging is to remove it from the charger and place it down again - not something I can do while I am sleeping.
I was wondering if there would be a software way of 'resetting' the wireless charging so I could use something like tasker to fool the charger into thinking it had just been placed down again when, for example, the charge drops below 95%?
Would this be better in the Accessories or Developers forum?
I own a Galaxy S2. I have tried it using for navigation many times only to find that the battery discharges fully within 2 hours even if the phone is connected to a car charger. I used to think may be its because my car charger doesn't provide enough current to maintain the charge. But recently I found out the culprit. After around 20 minutes of use, the phone battery starts heating up, and it stops charging. I verified this with CPU-Z. It clearly shows battery overheated, power supply connected and not charging.
I was wondering if S4 also has similar issue. Has anybody used it for more than 2 hours with Google Navigation continuously while connected to car charger?

The most I have used it for is about an hour and half, and while the phone did heat up, it did continue to keep charging while connected to my in-car charger (just a cheap one). I can't remember whether the charger was able to keep up with the discharge though, I think it did. I was driving in bright sunlight, so I had screen brightness on max throughout that time.

I've found that the USB cable can have a big impact on the charging current. I had the same problem with my car charger not keeping the phone charged, even though I was using a 2A charger. When I changed the USB cable I managed to quadruple the charging current (from 300ma to 1200ma) and solved the problem (I measured the charging current using the Galaxy Charging Current Lite app).

In my case, I believe it was not because of the charging current or cable. I was trying with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. When the mobile stopped charging, I checked in CPU-Z app. The app was clearly showing status as "power supply connected, not charging and battery overheated". If I unplug the USB cable and connect it back, it will start charging again!
To make sure that I didn't miss anything, I will try with the app you suggested.
Just to update: The Galaxy Charging Current Lite doesn't seem to work with my Galaxy S2. It doesn't show any value.
Hi,
Recently I've got my wireless charging pad (a well-known $27 generic wireless charger off eBay). Put my phone on, and it charged flawlessly and quickly enough. As soon as it got 100%, the charging stopped, and the LED on the pad turned green. No problem here. But, if I remove the phone and put it back immediately, while it is still at full capacity, the charging starts over and continues infinitely, as if it is connected to a wall charger. This concerns me, since the battery is being kept on trickle charging forever (about 20mA in screen-off mode according to Battery Monitor Widget), and the phone gets slightly warm. Besides, the charger unnecessary drains power from outlet.
I suspect, there's something wrong with communication between power receiver (phone) and transmitter (charging pad), since according to Qi standard, the power receiver should send an End-of-Power message to transmitter, as soon as the battery gets full, which in fact happens initially. But once the phone is removed and put back on the pad with battery still full, it seems, the message is not transmitted anymore, and that causes the pad to continue feeding power infinitely.
Could you please check your Nexus 4 with the wireless chargers you posses? I need confirmation, that this is indeed the phone's fault, and not the charger itself.
Follow these steps to possibly reproduce the issue:
1. If the phone is fully charged, play with it a little to drop the charge for 1-2%.
2. Put the phone on the charging pad and wait until charging process stops (your charger should probably notify that by some beep or LED color).
3. Quickly remove and put back the phone on the pad.
4. Observe what happens.
5. Report here.
Thank you!
Hello XDA!.
I'm new here, but oh well.
My Galaxy S5, Is having charging issues, comes and goes.
Using the Ampere app I'm measuring the charging speed.
Charging with stock AC Charger - 450mA - USB Charging, It won't charge at full speed 1.8 - 2.0A.
Charging with an Aukey Superspeed charger - 1.8A, Charges fine but sometimes stuck at 450mA USB Speed.
Charging with Anker Powercore 20400mAh . 450mA, USB Speed?.
I've switched between three different batteries, all of them does this, sometimes the phone simply tells me that the battery is dead, and it won't charge. ( Note: Phone won't charge but turns on with cable in).
What can I do?, buy a new phone?
Thanks.
