So right now I've got my phone charging off my wifes macbook. I've installed the % battery mod so I can see how much juice I actually have, and in the last 20 minutes of use its actually gone DOWN fron 11% to 9% while ON the charger.
Wtf? I'm on wifi with screen brightness on max, but shouldn't it still atleast maintain the original level?

If you're charging off the computer, no. A computer's USB port can only push so much power.

Exactly. USB charging is sooo much less powerful than the wall. Also, the Nexus right now is pretty bad on battery life and having the screen maxxed out doesnt help lol.
Lol am I the only one happy with the lowest screen brightness?

Probably, can't stand it any less than 1/3rd
A laptop can't put out enough power to charge the phone under use. Especially if you're using LTE. You'll have to use a wall charger.
Same thing happens when you surf using wifi while plugged into the wall, I made a thread about this two weeks ago.

Mine does same, GN is crap in this way, my iPhone 4 could easy do that.
on my Thunderbolt & Rezound, the phones would still charge via "Charging USB" while connected to PC even during tethering... so long as i was just doing simple web browsing. If i tried to download something or do some online gaming, then the battery would go down.
I found also that if i had them charging in my car, also in "Charging USB" mode & streaming music to my stereo via AUX, it would also lose power.
The same exact thing applies to this Nexus also. However, if i have it plugged into PC and do wifi tethering instead of USB tethering(much slower data speeds), then i can download/game and it will actually charge... just very slowly.
As for the car, if i use an actual power inverter so that it will stay as "Charging AC", then i can stream/download/etc and it will charge up normally.
I have some USB cables that have a mini-USB on one end & split off into 2 USB-A(male) connectors on the other end. they are intended for external Hard Drives that need more power then what just 1 connection can supply...
i think i am going to modify one & replace the mini-USB connector with a micro-USB and see what happens.
this is so simple.
if charge equal usage=charge will be 0+/-%
if charge is greater than usage=1+%
if charge is less than usage=1-%(batt drain even if hooked to pc or laptop or wallcharger)
not actual charging numbers. but just a figure on how it works,
this also counts for the wall charger.
Anybody else having the issue (or perhaps it's normal?) where running the Google Navigation app on your Nitro absolutely KILLS the battery...Even if you have your Nitro connected to a high-output power connector?
On mine, running CM10.1 RC5, even plugged into a 1.0A car adapter, the battery drains at about 1% per minute! The area around the CPU is super hot so I imagine running Nav pushes the CPU quite a bit...But this seems excessive.
Any thoughts on workarounds, fixes or alternate Nav apps?
Thanks.

that's why all gps devices come with a car charger, it's the nature of the system combination of screen on alot, powering gps device etc.
or are u talking about worse than normal ?

This is actually a fair question, as what is "normal" usage when it comes to using Navigation on our Nitro? Is the 1% per minute drain to be expected?

What IS normal is high current draw during battery use. What ISN'T normal is the battery drain when plugged in. Try a different cord or even a different vehicle. I have noticed that on some cars for me it won't charge at all, but won't drain, and on others it will charge slowly. I would suggest also making sure that the cord is rated for at least 2 amps. When I tried the stock cord and charger with a power inverter it would drain the battery with GPS use, just not as bad as you described. Also with screen off I get a drain of about 5%/hr with the navigation working. This has been consistent with stock or cm10.1 for me

it's actually decided by the wiring in the vehicle, and the adapter (which is either a car plug that has usb or a straight car plug -> micro usb)
i drive 3 differant vehicles at work and my car and have 3 differant adapters, i noticed that each adapter has differant charge speeds, and each vehicle does as well, my dollar store charger can't even keep up with navigation drain, a rapid charger will. however in my car i have 2 outlets, one in the center console and one in the dash, the center console outlet is more powerful than the dash.
so if u can't control your vehicle power buy a higher priced rapid charger.
if you really want good charge, buy an adapter that turns your car plug into a wall outlet plug, then plug the wall charger that came with your phone into it, that will probably be the max possible current you can get in any outlet, the higher quality the wall outlet converter the better.
if you notice you can charge your phone in a wall plug about 5x faster than a cheap car adapter plug
that is why they added a "slow charge" warning in some rom's to hint to people that it isn't the phone that is broken it's that there is a LOW current coming into the micro usb port.
there are also some kernels that will force a faster charge and remove some media transfer over usb capabilities, but i think that only works when plugged into PC (not sure)
I've noticed mine drain like this too. Nav annihilates my battery, if it's plugged in it still slowly drains. Maybe someone still running a stock ICS ROM can try it for comparison.
My old phone (HTC) also drained fast on nav, but plugging it in would result in a VERY slow charge instead of a slow drain.
The only time I experienced an actual drain when plugged in was while using the stock adapter on a power inverter. My car adapter plugs straight into the micro USB and us rated at 2A that is why I suggested a 2A adapter. Also to answer mpsantiago I experience no battery drain on stock ICS but on cm10.1 it actually charges faster. The only thing I can say is get a 2A adapter as the phone clearly draws more than the stock 1.2A adapter can deliver.

that's interesting... well i guess the moral of the story is just find a good charger, usually dollar store ones are garbage, also, use a widget like power toggles which has a multi setting brightness toggle, and turn your brightness low while your screen is staying on in navigation, my only suggestions. you could also try a new ROM or flashing firmware for gps hardware but i doubt that is worth the effort, if i use a cheap charger or use a bad outlet on an old work truck i have these problems with ANY ROM, but i don't have them using a good charger.
I love this phone and all, but it tends to have strange battery drain tendencies. As in, the screen isn't what drains the battery most, a lot of the time. :/
I happen to have the 6200 variant, if that makes any difference.
I had installed the yahoo weather app and went from 2 day on one charge to less then 8 hours on a charge. Some apps are a bastard on the battery..

Yes, Navigation kills battery. I too have it plugged into my car charger and while it slows the drain down, it can not charge it fast enough to keep up with Navigation's drain.
I'm running HO!NO!'s ATT V20f rom with the latest Wind Kernel. It's not just your phone. The Nitro gets hot and if you didn't have the car charger plugged in while running Navigation, your battery would easily be dead in about an hour.

You have to use a 2 amp charger with the navigation app with the screen on. As part of my job I am constantly using Google navigator. The cord I purchased was $40 and it charges fine, slowly but fine. To test this I borrowed a buddy's cheap charger that he bought at Walmart and sure enough I experienced battery drain, as it was only rated at 1 amp. The good news just hit the power button on the phone to turn off the screen. You will still get the voice guidance and your phone will charge or get a decent charger. BTW my charger has charged my phone no matter what ROM I used from Gingerbread to Jellybean.

good advice, but if you need the screen because of volume issues or you don't have a bluetooth stereo to make listening to audio easy, then you can just turn your brightness down as far as possible, i use power toggles for this its a widget with a brightness button that has up to 4 options, so you can push it and toggle through, mine is 10% 20% 30% 75% and there is a settings for auto, this is handy because depending on the sun at the time you want to be able to quickly swap between the lower brightness settings to find one suitable for seeing but that has minimal battery drain.

Hi everyone!
As you can see on the attached picture the device's battery life was decreasing while charged, i was playing a game with 40% brightness.
Can someone explain ne this, please?
Thank you!
Depends on what game you're playing. Asphalt 8 while charging for me only slowly charges, 1% every 15 minutes or so. If the game is using more resources faster than the battery can charge, it will decrease.

Not sure if that is totally unreasonable. 40% is significant in addition to gaming with a game that requires significant power seems OK.
I have the problem sometimes of my nexus 7 losing battery while charging sometimes as well, but I never use my stock charger and don't know where my original micro usb cable is. I have found that different Micro USB cables can have a major impact on charge rate. When the Galaxy S3 came out I noticed that with the stock charger and stock cable, I lost battery anytime I used my phone even while charging. My suggestion to you is to install the app current widget and put a widget on your home screen to see the amount of charge your device is receiving while charging. Yes you cannot do this while in a game, but you can at least test out different cables and chargers you may have to see if maybe one of those hardware pieces is the culprit.
The wireless charging seems more like a gimmick rather than an actual option for recharging the phone. If I leave the screen on (with a screensaver), the charging process from 70 to 100 will take forever (buh bye bed table clock), and if I use wireless charging on a car craddle (I adapted one), it doesn't supply enough power to even maintain the charge while driving with GPS + 50% Brighness + 4G.
Yes, it discharges while recharging. It's ridiculous!
When I had the G2, I remember few kernels that allowed the user to change the charging current in different scenarios, and one of them was wireless charging. I think it is limited to 1A stock, and the USB charges at 1.8A.
Is it a known issue, or is my G3 problematic? I also feel it takes a long time to recharge even on cable. My G2 used to jump easily to 60% within' minutes, from 15%. G3 seems to sip a lot, and recharges too slow.
--
and on a related note, sometimes when I place the phone on the wireless craddle, it says "Charging wirelessly" or "slow charge, center the phone bla bla bla". But most of the time it doesn't say anything at all, and just charges. Should I consider it slow or normal charging?
---------- After a brief test, it seems that it doesn't report if it's charging slowly or normally, horizontally. Even with screen rotation disabled, it just refuses to report. Weird.
How can I see the charging current? Is it even possible (I used to be able to do so on my Galaxy S3)?
You can use CurrentWidget: Battery Monitor from the play store to look at the charging rate.
I seem to be getting 0.7 Amps with my wireless charger which is just about okay, but yeah it will take time to charge if you have screen powered on.

It says 0mA, wirelessly or cable. What the heck?
Hi, I just got an LG G4 yesterday. Charging using stock charger, or any other charger I had no problems with S3 before, is really slow. As in obviously slow. The unit is estimating 3-4 hours to charge 30%-40% of battery. Once it took around 20-30 minutes to just charge 5% of battery.
Using Ampere app it is showing on average just 270mah charge. Sometimes it registers 1660mah, then it drops down significantly and settles with 270mah.
Using the dual sim model if that's any help.
Is this a new battery thing? Should I insist to have the unit (or the battery) replaced? Is this a hardware or a software issue? Even if i insist to have this replaced I want to be able to explain that this is a factory defect.
Same problem here..
Really annoying.

Same here, I think it charges at full speed when the screen is off...
I got myself a QC2.0 charger and its doing exactly the same.
It does appear to charge faster with it while the screen is off but I'm wondering if there is an update to the device that needs to be done to fully support QC2.0
i've buy an Aukey Turbo Charger Adapter.
Then my G4 has fast charging more about 75%
I've seen the same thing happen on mine. Highest current I've seen was 1650 mah. And that's with the screen off. Leaving the screen on it reduces to 270 mah

I had the same problem but it stopped after about week. Now it charges quite quickly and that's not with the fastcharge that isn't too impressive.
Same issue. Charging went from 2% to 46% in about 3.5 hours and it says it's still another 4 hours before it completes charging. Totally annoying.
i using the Aukey Turbo Charger and get around 1%-1.5% every min i have done 30%-70% in like 40min
I have a HTC quick charger that I used with my M8. It works well with the G4. With the screen off I have had nearly 2 A charging. It is much less when the screen is on.
Just got my G4 and it's doing the same thing.

are you using the screen while its charging tho? how many times have you charged it already since you got it?

my post was made during 2nd ever charging. i did turn on screen occasionally, but not like it was on all the time.
last night charge was shorter - around 5.5 hours.
This is really annoying trying to stream music and navigation sometimes losses a charge. With nexus 5 I usually gained 30 plus percent on my way to work on 40 ish minutes with car charger.
It "might" be a software limitation, to avoid pushing the battery too hard in its early cycles. Same as a brand new car, they usually tell you not to drive too fast for the motor to actually run with optimal parameters.
[2cents]
I am also experiencing the same. I am getting 640mA. It is really frustrating. Yesterday I connected the phone with the provided cable with G4 with my laptop. And i was using the phone, not heavy using. And actually the battery was draining, rather than charging. I got so frustrated. I found the phone actually charges better while staying idle & screen off, but not very promising.
Yep, add me to that list too. T-Mobile G4 with screen off and no use because I'm driving almost all day just to see a 5-10% more charge after driving almost 2 hours. The original charger behaves the same way too. The only fix I've found is to turn the phone off and charge it. It charges really fast that way only.

@fatboypup does this also work with screen on? Imagine using gmaps in the car, screen and gps active - it would be a pity if the g4 lost power in such a situation when on the car charger

As I noted above it is an issue with cars too. I'm lucky to gain 5 to 10 percent with navigation and streaming music in 45 mins. The same situation with nexus was over 30%.
Does this behavior stay or is it only for the first charges? Is there anyone who has no slow charging with screen on? Is the g4 gaining at least some percent when navigating with gmaps?
