On my previous device (an HTC Incredible), I found CurrentWidget to be an extremely useful app. Not only does it log battery level and voltage, but it measures the mA current being drawn from the battery (or being provided by the charger).
CW, unfortunately, does not read current on the GNex, which is mentioned as a possibility in the app description:
NOTE: The electric current reading doesn't work on all devices. The reason is that the manufactures (mostly Motorola and Samsung) don't support this in the battery driver or in the hardware.

So am I just out of luck?
Is there any way to measure current on the GNex?
There no way to measure current on this phone and most samsung devices cause this one uses the max17040 fuel gauge chip which does not output mA readings. Most htc use a different chip that allows this. Nothing we can do.

Is this what your talking about? Its built into the franco.kernel paid app, you will need franco.kernel.

Ouch; that really sucks.
Thank you though for the quick and comprehensive answer.

Unfortunately, no
mV =/= mA
They are measuring very different things.
I have been enjoying Franco's kernel and app though.
Battery Monitor Widget by 3c calculates an estimate based on battery capacity and voltage, but that's about it.

Thank you for the heads up. I was hoping to use mA readings as an independent check on other battery information, so unfortunately the estimate can't really accomplish that, but BMW still has some other features that make it interesting. I appreciate the recommendation.

Just wondering if there is an app to monitor the correct voltage and percent instead of trickle charging it or charging it in an external ? I mean its been out a while now...
Sent from my Evo!
nope, no app, doubt there will ever be one, or a modified kernel specifically for extendeds
Use any SBC kernel, there have been a few people with issues. I have used it for like 3 months with no issues. I use current widget and when it reaches 0 the battery is fully charged.

Bignipp can u explain that again? What widget do u use? I am using an sbc kernel but it didn't seem to charge my battery like the external. Im getting another battery tomorrow well see how that one charges
Sent from my Evo!
I guess you were talking to me (2 b's not p's) the widget I use is the current widget. It can be found in the market under that name. It measures current lost to current gained reguardless of the size of the battery so when it says full but still has like 350 mAh until its full to zero you can see it. I have it installed on my home screen. I am running netarchy 4.3.2 (I think it is) kernal with the SBC tweak and no undervolting and no bfs or cfs and it works flawessly.
Hope this helps

+1 for current widget. It'll show you your drain when not charging or net charge when it's on the charger. it'll also keep a CSV log on your SD card so that you can see how your device has been charging /draining over time, along with what services are running at the time the data is polled. It doesn't exactly do what you;re asking, but the phone will turn down the charging current as the battery approaches it's capacity, so you can infer that the battery is getting full when you see the charge current start to drop (the stock kernel starts dropping current around 65%, by the time you're at 90+% you're at around 100mA net charging current, not sure what the values would be with the SBC kernels, or how the stock kernel would behave with the extended battery)
Disclaimer: This is not not supposed to be another battery life issues thread.
So! I have been noticing that my nexus has been showing a slight increase in available charge without being plugged in. I never noticed this occurring on my thunderbolt and my old touch never made it that far along so I can't compare it to that.
I have calibrated my battery 3 times since I bought it and have been swapping ROMs. I am currently running Android Revolution 2.1.2.
Does anyone know what might be happening?

It happens. It's normal. Sometimes you demand too much of your battery. It heats up losing a little voltage but gains a little back when it cools down. Another epic reason uv'ing is valuable. Lower heat. It also extends longevity of electronics and your battery.

Its just voltage being under load and then being relaxed so it pops up a bit. Some phones exhibit this and some don't. It all depends on the type of battery driver used. Some like the max17040 use voltage to determine SOC and some use strictly coulomb counting which don't have this bounce effect. Most Samsung phones use the max17xxx fuel gauge using voltage, and most HTC phones use ds2784 and similar which just counts current, so no bounce.

Thanks guys, I had a feeling it was something like this. Thanks for all the info, especially the stuff about the drivers. I find it fascinating how something like the way a charge is measured can cause effects like this.
Anyone know of a app that works on the G3 to show the actual charging current the phone is receiving/using? There was one that worked on my last phone, the S4, but it nor any others that I've tried work. Just seeing if anyone has come across one that does work.
Try this one mate i had to press refresh a couple of times though to get it to register.

Tried that one and I don't trust the results. Every second the mA are drastically changing from 1mA to 950mA while it's plugged in. To my understanding it should be staying around a mA and not jumping all over.

App is indeed useless.
Well, you could use it as a random number generator, true.

I could send you a random number generator in CPP
Anyway is there an actual day to tell how much current it's drawing? Also I know the SD801 is QC 2.0 compatible, but do we need a software update to utilize a QC 2.0 charger the way it's intended?

Don't know, yet. On the SGS4 the Charging Current app worked quite well, haven't found anything so far for the G3 which is as accurate/at all.
I've read, don't remember where, that LG's way of charging differs from Quals and other manufacturers standards on the hardware level. So the G3 wouldn't be able to use the Quick Charge even with some software change. I've tried that Galaxy Current app and that reports negative mA when charging on the G3 so that's also a no go.

It's a baked in feature of the SD 800/801/805 chips so I don't know if they could disable it. I really hope it's still there just in case I need to use it (even though I have a spare battery). Is there anyway to know for sure?

Custom kernels for older phones had a feature that limits battery capacity to ~80?. This dramatically extends the life of your battery, as that last 10?-20? of charging will wear a lithium ion battery down significantly.
See this thread:
http://forum.xda-developers.com/showthread.php?t=1743977
Im a heavy user, I intend on keeping my HTC 10 for a long time, and I'd like the battery to hold a decent charge 2 years from now.
But after trying a few, I haven't found a kernel/ROM for my HTC 10 that supports this feature...
TL;DR Does anyone know of an HTC 10 kernel that lets you limit the battery capacity?

Make a request to an existing kernel developer to add this as a feature to their kernel.

Aaaaannnndddd it does work on the HTC 10
But if you deactivate charging it STILL shows as the phone charging and STILL has 7V on the Charger, but it draws 0.001Ampere so it's not charging.
Btw:
echo 1000000 > /sys/class/power_supply/battery/constant_charge_current_max
Needs to be typed every time you connect a Charger.

But it gets reseted when the display turns off, so make sure you check the Developer options "Keep screen active while charging"

It works, thank you! But how to set it on boot? All explanations I found were outdated respectively are referring to files which don't exist in Android 6/7 and the app Script Manager – SManager does not work on N at least...
Ohhh, that's why the app crashed xD
I guess any terminal should work.
Hi to all,
We want to announce new Motorola Moto mod we are working on, Solar Z sun-powered charger with battery.
Simply leave Mod in the sun and snap it to the phone when you need additional power and it will be transferred to the phone battery. Charge your phone without cables.
Time and knowledge have been invested in design and development and now we need your help to finish this product. We are about to start crowdfunding campaign, please follow us at:
Indegogo Campaign
Solar Z has a simple design and easy to use approach. It has no movable parts, one button only, however, electronic design is latest with high-level integration components.
It contains 2600 mAh Li-Ion battery which charges to 80% in 12 hours on an average sunny day, compatible with all Moto Z phones.
Let us know your thoughts!
as you working on the MOD design, is there a way to use the pogo pins w/o any extra circuit/chip to charge or supply with power?

Unfortunately no. Just short time after connecting Mod to the phone pin (corner top left hand size) is open (from phone perspective) and can accept charging. However, if communication through main connector between phone and mod does not exist, this pin will be closed from phone side and phone can not be charged. Answer is that you can not just hook ub battery or anything else to charge phone. You actually need micro-controller who knows how to talk to the phone.
