it's a screenshot from my device that I gave to the dev. It even went to 2430ma after the screen shot.

check this video I made when testing ampere (I made the screenshot while recording this video) : https://drive.google.com/file/d/0B0w34R--v2qIWVhYOW9LMnNLaFE/view?usp=sharing

I'm getting this with the supplied Motorola turbo charger.

I suppose that it's charging at 12v... and the ma shown here is based on 5v.

at 5v and 2430ma, it equals to 12.15watts.

on 12v, 12.15watts is just 1A... and the Motorola is supposed to give 1.2A at 12v
[Android Apps and Games] till22:
Thanks, didn't know yurbo charge increased the voltage. I can't imagine 12V being too good for the battery, although the low 1A seems to make up for it. I'm happy with my 2h charging time on N5 hehe
[Android Apps and Games] zadigre:
the Turbo charger is the motorola name for the Qualcomm Quick Charge 2.0. This technology can do 5, 9 and 12V.

I'm 100% sure that the 12V doesn't go to the battery without any conversion... the regulator inside the phone is probably converting this voltage to something lower with a switching circuit (or something similar).

Newer Lithium Polymer batteries can charge with a higher current without any problem...

The biggest enemy of those batteries is heat... this is why the charge starts with +2400mAh (according to what Ampere is showing)... and it will slowly decrease if there's some heat and/or after some time.
[Android Apps and Games] zgmfx20:
The rating of my charger is 1500mA but in the app, the reading is -170 on discharging and 1520 on charging. Is it normal?
[Android Apps and Games] zadigre:
probably yes...

-170 looks normal since this has nothing to do with your charger... but only your device using the battery.

1500mAh is only an average... so if your device is showing 1520... it's fine also.

The Moto X (2nd gen) has the turbocharging feature. I just would like to find out, on which interface the actual charge speed can be read. Because I don't own the device I would like to ask for a little help.

The Nexus 6 has a similar interface here:

/sys/class/power_supply/battery/charge_rate

It gives the following values by reading the interface: "none", "normal", "turbo"

Could you please help me, and find the interface on Moto X 2nd gen, which works like the interface on Nexus 6?

Thank you in advance!

I'm testing a magnetic charging cable on a Z3 tablet. Please correct me if im wrong.

1st image shows the amperage used on discharging. (180mA)

2nd image shows the amperage drawn using a magnetic charging cable. (1550mA)

3rd image shows the amperage drawn using its factory usb cable. (1070mA)

Using the magnetic cable, current being used+being drawn=the input to the device 1730mA? The rating of the factory charger i use is 1500mA 5V. If so, is this fine?
[Android Apps and Games] zadigre:
it looks fine... some device might not substract what is used to power the device from what is received from the charger...

also, a charger rated at 1500mAh can and will probably do more... it's up to the manufacturer to rate the charger properly.

the only way to be sure about that would be to use a special tool between the device and the charger that would measure the current that goes through the cable...

A description how to use Ampere on HTC M8

First of all, I disabled the app in Google Play for HTC M8 devices, because I got so many bad ratings from HTC users, and I will just enable it, if you confirm, that the App works great. Until then, please use the app from this thread from the first post.

After you start the app, you will realize, that the app shows 0mA, which is because the Lollipop interface is broken for most HTC devices. If you wait a few seconds, the app will ask you whether you would like to use the old measurement interface. You can say yes, or you can just select the same option in the settings menu.

After the "Old measurement method" is selected, please open the "Measurement interface" selector and select the third interface.

That's it. Now Ampere should show the charging current.

A last issue still exist. Because the firmware reports "not charging" instead of "discharging" in case that the charger is not connected, the discharging current will be not shown. While it is sad, I think it is not tragic.
[Android Apps and Games] platypoid:
I guess my device is too old - still have 0 ma on battery , continual searching for ma on USB with either method - just got newest Ampere 1.39 version

[Android Apps and Games] nihil0:
Please look if the "Measurement interface" settings options exist. If yes, this means, that the app has more than one measurement interfaces detected. You can just try out, whether one of them is working for you.
[Android Apps and Games] platypoid:
No - those options do not show up so guess this is not supported

I keep checking on new versions just in case there is some kind of breakthrough some day . But if the sensors are not in the phone I guess that means out of luck - ha ha .

LG G2: VS980 works I believe

I noticed no entry in this thread for the Verizon LG G2 (VS980). I used to use a widget a long time ago that showed the battery draw/charge, which was handy, but I stopped using it. Now with Lollipop my battery seems to be draining faster and charging slower, so I looked for that old widget app but couldn't find it, so I tried Ampere instead. It seems to work mostly, though the power drawn while not charging seems wrong - it's just -20mA no matter screen brightness or radios=off, etc...always -20mA. Oh well, moving on.

Device: LG G2 VS980 running Lollipop Extreme v1.1 (based on official 39A [Android 5.0.1] update and xdabebb's kernel)

Wireless charging from official LG wireless charger and slim non-TDU phone case, battery is at 78% - Ampere reports +20mV while phone is on it with screen-on. Rock-steady +20mA. This is ridiculously low, so I suspected Ampere simply didn't work with my device except it wasn't showing zeroes.

Wireless charging with case off, battery at 85%: Still camped out at 20mA. I believe it too because the last couple times I've tried to charge my phone at night on my other wireless charger, it claims to be charging but drains battery like 1% every 11 minutes (on KitKat my battery drained 1% per 60 minutes, yikes big difference). Yet at work it charged fine yesterday via wireless on this same charger that's showing 20mA in Ampere, so I don't know yet about wireless and how well it's working.

USB charging from PC: Plugged into a 500mA USB2.0 port and battery is at 83%: Ampere reports +330mA

USB charging from official LG charger, battery is at 84%: Ampere showing +930mA (max 1030 mA)

I haven't browsed this thread much yet, but I sure hope Braintrapp adds a historical view with logging and stuff. It would be great to see power draw while screen is off.

EDIT: p.s. The old app I used to use is Battery Monitor Widget, created by 3C. It has some ads that AdAway doesn't block, but gives you nice stats, history, graphs, etc. It was showing me a stable +15mA on wireless charger just like Ampere was showing me +20, but now with 99% battery on wireless charger it's showing +64mA. Maybe it changed since it's basically fully charged, but why would it go up from 15 to 64? More research and time needed, but at least it's working on Lollipop (for mA retrieval method I chose Real-time mA).

Does this support reading of charging off a turbo charger?

On my nexus 6 using this app there was only a .2 volt difference in charge rate on a normal charger vs turbocharger. Or am I just misunderstanding the whole turbocharg thing?
[Android Apps and Games] zadigre:
yes it supports turbo charging...

Charge rate will tell you if it's detected... it should say "Turbo" when a turbo charger is connected.

you might not see the benefit of a turbo charger if the battery is above xx % (I don't know exactly the value).

but if your battery is low enough (ex below 50%), you will see charging current of 2400mAh.

But I suspect this charging current is based on 5V even if the device is charging at 12V...

if that's the case, 2400mAh at 5V would mean 1000mAh at 12V which is about right.

Remeber that you have to use a good quality USB cable to get the full potential of your turbo charger... the supplied usb cable should do the job properly.

How accurate is this? I'm using a 2.1amp Verizon charger on my Moto X Dev. Edition (1st Gen) and only reading about 980mah
[Android Apps and Games] zadigre:
It's as accurate as your device can be...

Remember that only the current that goes directly to the battery is shown... So if your device is using 400ma to power itself, the charger is effectively outputting 1.389A.

Also, charging current is higher when the battery level is lower...

On my Nexus 6, I can see 2400mah when the battery is below a specific %... But when it's near 100%, it will be a lot lower than that .

A new version v1.43.1 Beta has been published on Google Play (and attached to the first post).

Changes:

* New: Setting option for "Enhanced Measurement" added

* Added: interface for GT-S6310N

Enhanced Measurement means, that Ampere tries to measure the current also if the state is "Not Charging". In this way the discharging current can be measured also with faulty firmwares (like the Nexus 7 2013 5.1).

I got Motorola Moto G XT1033 , and I'm using 2A charger..

so how to tell that my Charger are OK or great or bad...??

when I'm Charging my phone, from 30%, it says 900mA ,, it that mean good, or it should be higher than that, like maybe 1500mA or etc...??
[Android Apps and Games] TOLIPR:
.

Hi,

Charger power size depends basicly on the consumption for operating device and secondly on the overall accumulator capacity . Measuring software i suggest only shows the part of current going into accumulator, which will decrease successive in gaining higher capacity values to provide longer battery lifetime.

Negative *dis*charge would be a positive charge; it would be charging, not discharging. I believe the reported value takes into account the discharge rate of the device at that point in time. As you put it, 1090-230mA.
