I was watching the Mavericks vs Thunder game using the watch ESPN app and my nexus battery was at about 93%
I watch since halftime to the end of the game and I was plugged in to a car charger the whole time and when the game ended about 1 1/2 hrs later the battery had dropped to 53%. Can't understand it. Hope someone here can explain this to me.
Phone is galaxy nexus, obviously, the battery is the 2100 OEM battery from Verizon store, charger is a belkin dual outlet 1amp micro car charger with the cable that came with a Droid charge.
Thanks in advance ladies and gentlemen, I did look and search, didn't fins anything covering this specific issue.

5V right? that's not a huge draw at all on your battery, i'm assuming your car was either running or started right up afterwards...you can be certain your phone was getting that full 1A especially if your car was running. if your phone showed charging and your phone will normally charge from your car like that then you shouldve been in good shape. despite what you may think, i actually am trying to present relevant info lol but ummm other than that? i would definitely try a multimeter (.....if you have one.....) cuz that would show you exactly what you're getting in/out. usb pinouts should be somewhere on the internet. other than that, try doing the same thing (except for maybe a shorter time period if preferred) on a wall charger which should be more reliable and compare results. i've had devices that burn power faster than they receive them....but the good ole gnex? im not so sure. (engineer here).
I just recently join big red and coming from sprint with an evo 4g and didnt have this issue with that phone and same charger. I'm definitely going to try it with home charger to see if its the charger.
Extra info, the vehicle was powered on before I plugged in the charger, in case it matters any.
Thanks to all the reply thus far.

I find that under heavy usage, only the plug in wall charger gives enough juice to keep it increasing... and even that can go flat or decrease if you are really pushing it... also the way the battery stats are displayed can be flaky too... jumps in the level of charge and quick drops... hard to tell how accurate the reading is.
I hear you. That's crazy, basically the phone draws more power that the charger can provide. I would think the charger should be fine since its 1 amp just like the home charger.

Check in settings - status if it says charging (ac) or charging (usb) when plugged in you car.
If it says charging (usb) the charge amps are limited to 500mA.

The phone can use more power than a car charger can supply. This is commonly posted all over. Check your car charger, its likely a 0.5 amp. Buy a 1 amp or higher.

Your problem is the charger, 1 amp is the sum of the two outlets, hence you're only giving your phone 500mA max. When charging at that low of a rate, you'll drain the battery when doing anything power intensive on the phone. Your only remedies for this is to get a car charger that's capable of putting out 1 amp or more on a single line. What I personally did was get the Griffin Powerjolt dual charger for $8 on Amazon, opened it up, and soldered the center data pins on each port together.

I though that the griffin powerjolt dual outlet charger would dish out 1amp on a single port if the 2nd port was not being used. Interesting, I can see your point. Would you happen to have a picture of, or remember which are the two that need to be bridge inside to make it a full 1amp output?
Thanks in advance.

Okay, I tried what you said and I got weird results. I used the awkward griffin powerjolt dual outlet car charger. I tried using two different cables, one was from my girl's Droid charge and when I plugged it in and check the status it said usb charging, then I plugged in a cable that came with a i go green adapter that I had purchased at an airport and the phone said ac charging. Unless the cable that came with the Droid charge can only pass 500mamp, I'm puzzle.
Both were plugged in at same time and also both cables were tried by themselves in each outlet of the griffin charger by themselves.
Interesting huh. I will keep testing and see what gives, last resort I get a more powerful car charger. Will keep you guys posted, thanks to everyone that contributed and pitch in thus far.

Got an update on this issue. I streamed another 45 mins to 1 hr of ESPN using watch ESPN app and the results are even more interesting. I was using the wall charger that came with the Droid charge and the USB cable that came with the I go green wall adapter that I have purchased at an airport a while back. Here is what happened, when I started streaming the battery was at 94% and I plugged in phone to charger and under settings/about/status it showed AC charging. After 45 mins to 1 hr of streaming the phone was extremely Hot towards the center of the back and below the cam lenses and led light. Also the battery had dropped to 93% and the phone status showed not charging, even though the battery icon on home screen next to clock shows the lightning symbol inside the battery like is charging.
I don't understand what is happening. Grrrrrr. This is using a wall a charger for a droid charge. Now of to trying it with the OEM charger and cable.

Exactly, in the driver i think the overheat is set to 140F. Also when your charger showed as usb it only gets 509mA and when showing ac it gets the full 1 amp. So just pay attention next time and see if it drains when showing ac.
My car charger is a 1.3 amp and always shows as ac and never drains while charging.

I though about that but then I was wondering, shouldn't the wall charger provide enough power to run everything in there while charging the battery or even without the battery in the phone. Like shouldn't the battery hold the charge that it already has when I started streaming as long as the charger is 1amp?
I would not care if when I stream the phone battery would just hold its charge at what it has at the moment even if it does not charge while streaming. Hopefully that is clear to understand.
To all the fellow galaxy nexus owners out there, maybe you all can test on your phones and see if you get same results as me. Download watch espn and stream the channel for 30 mins, notice what is your battery level before you start streaming, of course plug the phone to a car charger or wall charger and see if battery remains the same, drops charge, or gain charge at the end of 30 mins, or maybe an hour. I am not asking you to watch it for the 30 mins or 1 hour, just let it run and see what happen, if you can of course. only reason why I ask for watch espn is because it is the app that I have been using to stream nba games for the last few days.
Another thing since I am already here with this streaming issue, I have an original SlingBox, the cheapest of the cheapest when they first came out, just coax and that is it. I would like to know if I pay the $29.99 for the app from the market when i switch roms on my galaxy nexus would I lose the app? I have already unlocked and rooted my galaxy nexus and lets say I buy the app and I am running cm9 when I purchase it, if I change to gummy rom or back to a stock rom while still rooted would I have to re-buy the app ?
Thanks in advance for all the input.

No I haven't try that. I am currently testing out roms like a mad man trying to find the best for my liking. Question for ya, As far as I know that is kernel dependent right? Like the kernel has to support it, if so which kernels do support it and what would be good underclocking settings ?
I get similar results while using navigation and pandora at the same time, the phone uses more juice than the car charger can provide.
Ironically I plugged in the oem charger and oem cable from the galaxy nexus box and open it (didn't really wanyed to do that) and streamed 30 mins of espn on watch espn and battery was at 70% when I started after 30 mins streaming it had actually climb to 78%. Confused yet everyone? What gives?
Sent from my PC36100 using xda premium
Not all that odd. Using my Fascinate charger (0.7 amp) I get noticeably slower charge times than the OEM charger (1 amp). I don't use my phone much while I'm charging so I can't provide any feedback for that.
What is the Droid Charge charger rated at?
Any car chargers that anyone could point me to that charges as fast as a wall charger?
As it is right now, unless I have my screen off and no apps running it drains faster than the charger can put juice into it...
I'm just using an el-cheap-o aftermarket car charger.
Thanks!

What I use is a cig to usb plug (cost me 10 bucks at walmart). Then I bring the cord from home that came with my phone and plug that into the USB to cig thingy. Works like a charm, I haven't noticed it charging slower than when at home.

All I know is that now I can run my GPS with the screen on and still move UP in battery - before it would drain faster than the car charger would charge, so, I'm happy with what I have now.
Actually the problem is that some of the car chargers are not at 1amp output but less .75 or .85. Thats why your not really seeing an increase. The stock charger is at 1amp. I know AllGamer likes to use the Blackberry ones (which i believe are 1.5amps) Correct me if im wrong AllGamer.
So just look for 1 amp car chargers the cable doesnt matter itll hold whatever you attach it to.
So, no matter wht brand charger you have as long as you connect the two middle pins you will get full charge as long as the charger can put out 1000ma?
I really need a good charger for the car, right now i use a blackberry charger at work an it charges pretty fast. But i need to know how do i find the currect charge rate of a charger. Is there an app for that?
Get tmobiles car charger. Its faster than any others I've tried.

I need a great car charger and really dont want to spend to much money on it. Furthermore, if I am getting a 1+amp charger, as long as i am using the stock samsung charging cable then it shouldnt matter if the charger itself has D- and D+ shorted right?
Im assuming this is something standard on all usb CHARGING cables as appose to data cables.?

You want a good reliable charger at eBay pricing..... spend the money 1 time and be done with it. You could've already gotten the T-Mobile one and been done with it.

For those of you buying the USB 12V Cigarette adapters read this.
Basically if you use a data sync cord with one of those adapters, unless it shorts the 2 data pins together internally (probably not) the phone is going to think it's plugged into a computer and only charge at 500ma (max output for a computer USB port). The write up above explains to short the 2 data cables together (this is done internally with the main AC charger head) back towards the phone so it will charge at 1amp instead of 500ma.
You can buy this cable and just modify it as described. I bought this USB adapter so I could charge 2 things at once.
Let me get this clear.
All i need to look for when it is charging is AC mode. As long as it says that, it doesnt matter what i have or have not done to the cables, AC mode is AC mode.
The charger i am looking at getting is 2.1 amp (because it has a spare usb port...so 1amp per line) and when i plug it in and it says AC MODE then its good to go right.
I just bought a TMOBILE offical charger that shows AC MODE, so when it MONOPRICE charger arrives i can compare. If it doesnt work its another 5 bucks, if it does i can take the tmo one back.
But again i am just wondering are there any caveats to AC MODE, or is it that once AC mode shows that is all that matters.
Hi guys,
I am running a custom rom, (Pkmn v2), but over the weekend i did my first test of the MHL.. watching a divx 90 min movie on a bigscreen connected via hdmi.
Even though the mhl was connected to the mains (and the red charging light was on the phone), the phone wasnt charging (or even just running on mains), i lost about 40% battery from the start to finish of the movie.
Has anyone else tested the mhl.. seems a bit stupid that it wouldnt run off the power that is plugged in.. is this a bug in general.. can anyone else test.
Tested it a while ago. Mine does charge. No problems at all with MHL adapter.
I'm on ARHD 5.0.
It charges the phone, the thing is... the phone drains battery faster than it charges when connected to MHL.
This was the case with my Nexus, and i'm guessing its the same case with the One X.
My mhl adapter splits the current , 500ma to the hdmi bit, and 500ma to the phone, it is expected for it to run out

What charger and cable were you using? some non-oem chargers & cables won't give enaugh current. Watching HD Youtube videos, my phone was charging until it became green.
I'm getting rapid battery drain issues while using MHL adapter. I'm still trouble shooting, but have to experiment more. In the mean time, I was thinking maybe someone may have some suggestions.
I just transition from the HTV Evo 4G. Great phone, but it's showing its age. I have a job with a lot of dead time. With the Evo, and Cyangenmod, I would mirror the phone onto a 16" HDTV and watch Netflix, Hulu, NFL, Crackle, Plex, play games and so forth. I would also WiFi tether so I could use my tablet to do email, web browser, IM and so forth. I had the phone over clocked and used the performance gov. If had the phone connect to a charger, it would actually charge, albeit slowly back up to a fully charge This is with the screen that new shut off while pausing a media, but set to the lowest brightness.
The GN2, nowhere near the performance. If I WiFi tether and stream some media and mirror to the TV via the MHL adapter, I loose around 20% battery.per hour. I have power save on. I use my tablets power adapter with outputs 2.1mah instead of the 1 like the one that comes with GN2. I still have the screen set to lowest brightness.
From the settings menu for battery, the screen takes up the most juice. This is expected. But I also streamed content on phone while charging and it did build up a charge, albeit very slow.
I'm thinking it may be the MHL adapter itselt. I have the have USB charger connected to work. It's possible the phone doesn't put out enough power to work the MHL adapter. I'm not certain, but it's possible the MHL adapter is only doing a trickle charge. I had it plugged in, but phone screen off, and looks like it draining the battery. I want to run a longer test to confirm.
I purchase a cheap MHL from monoprice. I had to get the 11pin to 5pin adapter to use it. I'm not sure it is the MHL or the adapter that may cause issues.
In the mean time, I changed the kernals to Persus. Hoping to get better performance, or higher charging capablities. It's improved slightly, maybe 18% drain per hour. I'm just using CPU Mater, free version. I upped the CPU to 1.8ghz, but the free version does include anything for the battery. I don't really want to spend the $3 on SetCPU because I don't know if there gov has a lot towards the battery charging mods.
Any ideas or suggestions?

A. you are wrong, the charger that comes with our phone is 2 amps.
B. make sure you use the cable that came with the phone as it is rated for 2 amps, other cables will have too much resistance
C. it is normal for the mhl adapter to eat through your battery, maybe not as much as you are saying, but this phone uses the 11 pin mhl adapter which allows for FULL hd unlike older mhls/microhdmi ports so it is bound to murder your battery
D. I don't recommend you wirelessly tethering at the same time, my phone will eat through my battery like crazy with the screen turned off while tethering to play online games... this might be the root of your problem

I think you're right on the cable. I tried it at home, using the charger and cable that came with the phone. Did an hour of Netflix, WiFi tethered the tablet. Battery drain...1%
I'll guess I need to get new USB cables since I like to keep extras in various locations, LOL.
Also, I miss read the chrager. I shouldn't read when I'm too tired. The good news, my tablets 2.1A charger should be only a very low risk of too much power. I was concerned with it, when I thought the charger was 1A
I realize what I'm doing is power drain, but it should be doable is the phone is on a charger. I'm not necessarily expecting it to charge back up, but I figure in the six to seven hours, a reasonable drain on the charger should be maybe 30%. This is only an assumption since I don't know how much the screen drains the battery.

there is no risk of overcharging from amperage, the phone will take what it wants and not use the rest... you could have a 500 amp charger yet our phone would only use the 2 amps it's rated for. The problem comes from voltage if you have to much voltage then you overcharge.
you also fail to realize that the phone takes a lot of juice to convert it's image into a standard hdmi signal, it's the difference between you talking to yourself and you trying to make someone else understand you... the processor has to act as a graphics card, a sound card and its usual processing needs... the epic 4g touch ate just as much power per hour while on mhl yet it was only outputting 16:9 480p
as for getting more cables be careful and ensure they can handle the 2 amp drop
Sent from my SPH-L900 using xda app-developers app
Well, it seemed the biggest culprit was not the cable, but the charger. I actually brought the Samsung charger to work. I was only getting around 2% to 5% battery drain per hour. It was really low.
Unfortunately my ignorence on electricity is showing. I'm not seeing why such a dramatic difference between the Samsung and ASUS (TF700T tablet) chargers. Their readings are similar but not exact:
ASUS: Input: 100-240V 50/60Hz 0.5A, Output: 5V==2A or 15V==1.2A
Samsung: Input 100-240V 50/60Hz 0.35A, Output 5V ==2.0A
As for cables, I'm not sure where I can go to find good USB cables that work as well or better than the one that came with the phone. Usually I just go to monoprice, but that's where I got my other cables.
BlackBerry cables r usually more beefy than others since they are rated for data transfer. whenever flashing through Odin that's what I use never had a problem. assuming it's the same for charging. they usually only run like 5 bucks too

they might be beefy, but still have ****ty materials. it all depends on the impedance of the cable... if you have a multimeter check the resistance on the cables and compare them to the stock

Hey guys,
I currently own a SG4 and briefly tried the older HTC One, but returned it because it didn't meet my specific needs.
I use my phone in conjunction with an APPRADIO headunit so max charging current, battery life as well as a fully functioning MHL adapter (capable of supporting 2amps) is required.
Currently my SG4 has no problems keeping up with current draw and can even charge while in use, however the M7 I tried could barely make it half a day. The only reason I'm comtemplating replacing my Sg4 is due to a BT compatibility issue with Samung and APPRadio that causes BT drops, hence causing me to lose control over the screen via headunit.
My questions to you guys are:
Can you guys charge your M8's at 2 amps?
Can you charge at 2 amps with an mhl adapter installed?
How does the MHL adapter work for you guys?
If you can charge at 2amps, does it require a custom kernel (fast charge)?
Anyone?

Just to clarify, I'm not taking about QC 2.0, just standard charging at 5v 2a through a MHL adapter.
It won't charge at any higher a rate then the phone is designed for. No matter the charger.

Doesn't answer my question at all.
Phone was designed to charge at QC 2.0, which is much faster than 5v 2a.
All I'm asking is if someone is actually getting 2a charging with a mhl came connected.
Good luck! ?
Just wanted to chime in about your setup. I have a very similar one in my car right now, however, instead of an appradio, i'm using mimicsX2 and the stock radio's video input. But i'm typically running media apps, streaming, screen on, etc. Instead of an MHL connection though, i'm using a wireless miracast adapter (push2TV). So far, it's been amazing. I can still charge the phone while using all of that and while it does get a tad warm, it's not enough for it to be much of a concern. I've read that people have hooked up miracast adapters to appradios and that it does work fairly well. The only downside i've seen so far is a ~half second delay with interactions. But to directly answer your question, in my experience, charging isn't an issue.
EDIT: Forgot to note one other thing you might want to know about MHL. It seems like only stock-based ROMs work with it, and the adapters are quite limited. If you get an adapter that is MHL 1.0 it makes the phone run at 24 or 30 FPS and the UI lags like crazy. However, all of the 2.0+ adapters all seem like they are the short variety, so if you're trying to hide the adapter somewhere in the car and just run the one wire out, you may need to buy an extender. ALSO, note that the M8 uses standard MHL and NOT the proprietary 11 pin one that Samsung uses.
EDIT2: Looks like monoprice has them on sale today for ~$7 (double check that this is MHL2.0 though) http://www.monoprice.com/Product?c_id=108&cp_id=10833&cs_id=1083314&p_id=8675&seq=1&format=2
I think the software only allows the mate to charge at 1500ma tops as of now.
Really unsure, because the stock charger provides 1.5A of current. I don't have a 2A charger to test, sorry.
