I tried Elixir 2, and Current Widget to see how quickly my charger is charging my Gnex, but both of them wont display the Current.
Anyone know?
Oh, im on Cm10, 4.1.1
Try Battstatt or Android Assistant

The fuel gauge used in the gnex max17040 does not support mAh or mA readings. It only reads volt and temp. Other phones from htc use different fuel gauges that output those values, but most Samsung phones do not since they stick with these fuel gauges.

Is it normal for the charge to charge up extremely fast. I'm using Francos kernel 11 on gummy rom.
I just bought this phone and noticing it charges 10 times faster than my nexus s? Is this normal. I wiped my battery stats already

As it seems Samsung delivered a stronger power supply with the gnex.

Thanks didn't know if it was normal or not. It charges without exaggeration at least 10 times faster. That's good to know I no longer have to wait for 5 hours for a full charge
Sent from my Galaxy Nexus using xda premium
Since I had the sgs2 beforehand I tested both power supplies from 25% battery and the gnex power supply was definitely faster. Hope that proves my point tough I dont know the timings anymore

Those with a Verizon Galaxy Nexus, can you look at your charger and see what the output is?
Some of us GSM users got some generic Samsung one, so might not be optimized for the Galaxy Nexus.
So is it 5V, 2.1Amps or what? I've been using my iPad2/Touchpad/Transformer charger with my GSM version and it charges super fast cuz of the high amps.
It charges much quicker that my Galaxy S with a bigger battery on the same charger (the one from the Galaxy S, 700mA). Seems they made charging much more efficient in the Galaxy Nexus.

I don't think a bigger amp charger charges faster. I think the nexus is limited to 1A. I've tried a bc 1.1 compliant usb hub which allows charging of one device at 1.5a and I noticed no difference mentioning. But yeah, using a 1amp charger charges nexus ridiculously fast.

Its definitely not samsungs. At least I don't think so because its kind of fancy looking compared to my vibrant, tab,nexus s look. Its also really tiny I mean extremely small just big enough to have prongs

I think the fast charge is better on the battery. You don't get as full but it prolongs the battery. I read that hear some where

5V 1A is the standard for US wall chargers. My HTC ones, Belkin & Kingston ones are all that way also.
[EDIT] i actually just went through my box of cables/chargers and even found a Griffin one that's 5.2V 1A. i should be using this one
I installed Battery Monitor (a few bucks on the market), among many features, it shows the actual charging and discharging rate. On average my GNex charges at 1200+ mA per hour without use and discharges on idle between 2mA-350mA per hour screen off depending on background processes. I have the 2100 mA battery and average 2hrs for 15%+- to 100%. The stock charger is definitely fast with an exceptional charge rate averaging well over 1Amp per hour when uninterrupted.
**Edit: when charging & using the device I average 650 mA charge rate. Still respectable.

My GSM one charges full in at least an hour or two. And NEVER FREAKING DIES. This is the first phone ever that i can charge fully and let it go a full day into the next day and i know it will still be alive. I remember i let it stay alive for two days straight. only reason why it only lasted only 1 day, 2hs and 35mins this time was because i flashed a different rom. Only had the phone for a full week including today. Been reading alot about this franco dev. Does every rom currently use his kernel? Just flashed gummynex and i don't know if its running his kernel or not. A little off topic i know but its still pertaining to battery

You do know that the nexus doesn't have a chip capable of reading or outputting current? So anything software tells you is a guess.

Okay so, my last phone was a Droid X2 and I got a 3500 mah extended battery for it. It was on Android 2.3.5 and Android's battery meter did not correctly read the battery's percentage.
When it got to 1% battery it would simply stay there for a while before it died.
I am wondering if this problem is fixed with the Galaxy Nexus or ICS in general?
I purchased a Seidio 3800mah battery and I'm curious to know if I can rely on it's battery readings.
Thanks in advanced!

I have the official Samsung Extended Battery (2100mAh) and it reads it perfectly. Charges all the way to 100% and then dies at 0% (doesn't hang at 1%).

Thanks for the quick response
I see you said you have the official battery and I'm wondering if there's anybody with a non official battery (if that even makes a difference).
Also I'm wondering about high mah batteries such as the 3800 mah from Seidio or another from Mugen Power.
Thanks
The percentage comes from the chip in the battery, not ICS. So any official battery would output the correct SoC which the driver can read. A cheap battery may or may not depending if that manufacturer setup the chip correctly.
Android 2.3.5 was identical. If it was a 3500 seido they typically give correct charge. If it was a cheaper one then thats why your droidx didnt display properly.
Has to do with the fuel gauge chip, not the OS. Galaxy nexus uses max10740. Nexus one used ds2784. Droidx was totally different too. All depends on that chip.

Yes it was a cheap off-brand battery and that probably explains why it wasn't showing correct percentages.
Thank you!
I've seen a similar subject for other phones but not for the GNex. I bought some OEM batteries off eBay and turns out they're fake... not only does the NFC not work but they also put out 3.8 volts where the real battery puts out 3.7... Does anyone know if this is safe to use. I really don't want to jack up my phone from using a bogus battery.
With other phones it seems that the main problem is the battery will not charge fully unless charged in the dock. I've used the battery long enough to check the voltage and if the NFC worked then took it out.

I'm not sure about the gnex specifically. I have an extended battery in my G2 and on "battery widget" it says it's 4.19V, on the battery the label reads 3.7VDC. It is a ebay china battery. I can't say if the widget is accurate or not, but I haven't had any issues on my phone.
Lithium batteries fully charge around 4.2v, 3.7-3.8v is for storing the battery long term. Since at that voltage there isn't much stress on the cells.
Thanks for the info. I'll just have to assume since the guy has sold quite a few of these china batteries that none have blown up yet or else it would have been reported on eBay.

ok guys you can laugh as much as you want but i did it lol . i used to have the nexus that google used to sell which was a great phone i had 2 backup batteries for the phone . i was looking at my note two and note 3 and was looking at the difference in battery in each one and found a way to run the nexus battery on the note 2 and the note 3 lol it looks ghetto but works and i never have to run to charger. look at the pics
you can see the size difference in the battery size is major but the battery for the nexus does last pretty damn good for some reason. on the nexus battery on the side where the metal connections are i shaved off the tabs on that side look at pics lol

Well the battery from the nexus was just sitting in my desk not being used being that ibsold the nexus . So I was like wait will this work in my note 2 and 3 it did. Very little mods needed yo be done other then shaving a peace of wood or plastic to hold the battery in place and shaving the tabs on one side off so it would sit flush against the pins .

It might run okay for now, but in the end you'll blow up the battery and make the phone unstable. The GN3 battery is 3.8V while the GNex battery is 3.7V. Yes, that 0.1V makes a difference - the phone will charge the GNex battery with a too high voltage which can cause it to overheat and swell. The phone running off 3.7V will be underpowered and might or might not randomly crash.

It's not that big of a deal. Lithium batteries have an upper limit of 4.2 Volts which is why if you use a general purpose charger such as those used for charging RC packs you can charge Li-Ion and Li-Po batteries both on the same setting. Either way it charges them up to 4.2V and then cuts off. Once a load is applied, the battery drops to its nominal voltage - 3.7 or 3.8V and remains at that level for most of its life before rapidly dropping off when it gets low. When this happens cut-off circuitry kicks in around 3.2V or so to prevent the battery from discharging too much which will permanently damage it. Since the battery can't be safely charged above 4.2 or let drop below 3.2 or so, all the charging and discharging is managed by a chip designed for that purpose. Also, it means that you can't overcharge your battery by leaving your phone plugged in 24/7 as the charging chip will stop charging when it reaches that upper limit.

Lithium ion batteries with a nominal 3.7 voltage should be charged to 4.20 V or so.
Lithium ion batteries with a nominal 3.8 voltage are typically charged to 4.30 or 4.35 V. It's a new type of lithium ion battery with different chemistry, and hence the different voltages. If you take a battery meant to be charged to 4.20 V and repeatedly charge it to 4.35 V, its cycle life will be significantly reduced. 0.1 V difference will reduce the cycle life by something on the order of 50%. Here is a reference: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
Apple, Samsung, and Motorola seem to be using this new type of battery, and the phones are charging them to 4.30 or 4.35 V. I'm not sure how widespread the technology is or if it has trickled into aftermarket battery offerings.
I commend you for your work and glad your getting more battery life with this mod but I'm sure most of us are fine with the life of the phone stock gives us without any modifications or just wait til zero lemon releases their behemoth 10k mah battery with zero shock case to protect the phone.

awesome. this means i will probably be able to stick 4pin samsung batteries in my note2. must be sure the 3 pins on the note2 correctly connect pos and neg with the plates on the 4-pin batteries. in a few years the note2 replacement batteries on ebay will have shorter lifespan due to storage in the warehouse. instead i may purchase a battery for a then current model (such as galaxy s6 battery) and stick that that in my note2.

But with this new 'smart battery' and 'smart charger' system it seems very likely that the battery's capabilities are read by the charger so that the charger will not cause damage. It might be that the charger will adjust the charging protocol if it can support the battery's needs, or perhaps refuse to charge an unsupported battery. I think if he measures the charging voltage he might find that it is different for the two batteries.

Thanks to this, I will have more battery life. Cheers! Just kidding!

It is claimed that Galaxy Nexus is using Maxim 17040 fuel gauge. I wonder is it possible to get the real time battery current,voltage and capacity information from the kernel of this phone or Nexus 5.
Uh, isn't it just at
/sys/class/power_supply/battery?
There's capacity and voltage. Couldn't find current draw though.
