Hi
Using today the phone @ 100% brightness with car charger connected and using Sygic / Copilot, I see that my device can't not even charge at the same time that I am using it, but maintain their % of battery. Even with the charger the phone drains battery.
WTF samsung, So i cant make a long travel without running out of battery?
Anyone more with this problem?
PS: My HD2, HD, TyTN2, etc doesn't have this problem with the same car charger, they even charge at the same time.
What's the rating on your charger? I had to swap mine out for a 1A one in order to cope with GPS use in the car. Haven't had a problem since then.
I suspect the one you're using is 750mA or even potentially 500.
I have just had the same problem. I knew i needed a higher amp charger but i thought i would give it a try. The one i used is 650mA, so that's definitely not large enough. The normal 'house' charger is 0.7A (700mA) so in theory that size or above should charge whilst the S2 is being used.
I have a 1200 mA usb adapter for car (a sony ericsson, very very slim one) and I have no issues. You need a decent amount of power for that phone so 650mA will not do, have at least 1000.

Not sure if this is the exact model but I found it to be the best because it's slim and there is nothing sticking out of the car socket, has a lot of power and I can power any usb device with it.

Yest but probably you hava a chinese charger. The rating on it is never near the real one.
oh, I see, crappy charger, ill change then thanks guys
TomTom recently released a high speed multi charger. I replaced my old car charger with this one as I had a similar slow charge problem. Never had a problem ever since. All my weapons are always fully loaded with enough power! Expensive though!
http://www.tomtom.com/en_gb/product...-cables/high-speed-multi-charger-9UUC.001.04/
If someone is using a cheap higher-powered mains adaptor without issue, could you please post a (UK) link? Also if anyone knows of a cheaper alternative to the £20 car charger that would be great too!
I had same problem.I bought Samsung charger and no problem after

2.1 Amp TomTom charger is way too much for this device. Samsung wall charger is only rated at 750mA, but someone even found out that in source level Samsung has limited the power current at only 650mA.
With 1 Amp (1000mA) top quality car charger, the phone lost charge while using Navigation on full brightness.
Very slow charging in general for this phone.

When you have the car charger plugged into the phone go into Settings/About phone/Status & look at "Battery status"; it should tell you if the phone thinks it's plugged into a USB port (in which case the phone will draw only 450 mA) or an AC charger (from which the phone will draw 650 mA). These limits are built into the Samsung ROM, presumably to keep the phone cool and/or extend the battery's lifespan. They could be overridden (especially the AC charger current limit) in a custom ROM.
Absent a custom ROM, if the Status display says you're connected to a USB port, you could try a different charger, or connecting USB pins 2 & 3 (the two center pins on the USB A connector) together. That's how the phone decides if it's connected to a USB port or AC charger -- the low-resistance (less than 200 ohm) connection between the two USB data pins is the key. The spec calls for 200 ohms resistance between the data pins, but some of the low-end high current chargers I've seen just have a direct short.
If that doesn't work, or if the Status display says you're charging off AC, then try some of the other battery-life tricks documented here in the forums; they should reduce the device's draw from the battery, allowing the charger to do its job.
Wow, this is kind of disappointing i have to say. I have noticed the USB charging is incredibly slow. You can't ever rely on it, i think it would take close to 5 hrs to fully charge from USB, that's insane! By mains it's somewhere between 2 and 3, but that's still way too high.
I take it if you buy a higher-powered mains adaptor (not one for the car) then we'd definitely get the benefits of a faster charge? Can someone post a link to one they are using and know works faster that the stock one?
Cheers
I ll try ur tricks guyz.
for the time being this is my situation (and it sux):
-car charger 1A 5v
-slow chargin and hot device
-using navigator equals : phone burns, drains battery and in the worst scenario freezes
yesterday I received a call while phone plugged into car charger with navigator session. wot happened is phone freezed (screen didnt switch off) and I saw PROXIMITY SENSOR WAS RED!

The first post got me worried for a while, but this info has put me back to ease. Pre-ordered the GS2 (India) and getting the original Samsung charger along as a freebie.
Yeah, i have simelar experience with the samsung s2 in my car.
Its eating the battery even when its plugged in and i think i have a good charger..
I found 1 solution.. I use now copilot, you can set different setting to disable the screen automatically when you drive a straigt forward for some kilometres, only when you need to turn it comes up again.
thats how i set it and it loads a little, but bad anyway.
Maybe thats what the + means in Super Amoled + (+batteryusage)

Hey guys, while this information may be redundant to some, this is my first 2A charging phone having come from a GS2. A few note's i thought i'd share about fully utilizing the maximum charging of this phone. Using Elixer app, i was able to determine a few tips when charging
CABLE LENGTH MATTERS
I went out and bought some nice long monoprice cables, 10' and 15', i hated the feeling of being sucked to the nearest wall when you wanted to charge and use your phone. Plugged it into my nice new S4 wall port with a 10' cable, and checked the amperage being sucked in, to my surprise it was no where near the 1900mA max i should be getting. Went to the 15', even lower current (duh, for those who weren't able to put that together), went back to my 6' cable, boom, back up to 1900mA.
TLDR: 6' max for maximum charging
PAY ATTENTION TO 3rd PARTY SPECS
often times these specs are misleading on amazon and such. Often times you will see a 2A car charger with two ports! Awesome, but sadly each port is usually rated for 1A each. This will not be enough to output a full 1.9A (1900mA) for your device. You need to look for 3.1A rated two port items (2.1A and 1A port), or 2/2.1A output for single port chargers, or for true dual charging, a 4.2A rated with each port rated for 2.1A. They do exist.
Also, pay attention to whether the device is iPAD (or any dumb iDevice) certified or marketed to the iCommunitiy. Often times even though the dual port chargers with the 2.1 and a 1 amp port, the 2.1 amp port does NOT have the correct data ports shorted out. What this means is how the phone detects the power source. When you hook your phone up to a computer, there are channels in the USB cable that tell the phone it will be using data, this then limits the amount of power it will draw. The iPAD chargers are set up this way where the data ports are not shorted out, so your phone will not suck the full amount of power. To bypass this, you either need 'CHARGING ONLY' USB cables, which short out this channel for you, or you need to mod the charger with some light soldering. Often times i find this iPAD issue on the ones rated for 2.1A, the 2A chargers generally do not have this issue (just a generalization on the marketing of the chargers, not a fact)
do some reading on the spec's before you blast the product, i hate it when people bash it when they buy the wrong thing and it's their own fault for not taking the time to research it. And if it's not clear, don't buy it!
Ok, that's all i have for now, hopefully this helped some people out there. make sure you do your reading before you write up posts about your phone charging slow, or bash a product you bought because you didnt understand what it was truly designed for.
My adapter is getting warm while charging. I'm on my 2nd note 3 because the other one stopped charging. That could have been the cord as well, but I was still under warranty and got a new device. I have a LG travel adpter that is probably for a G2 and that adapter seems to handle more power based on the numbers. I'm not an expert though.
It's normal for chargers to get warm, particularly modern ones. Lots of charge goong through it.
What are the numbers for the g2's charger?

.3v isn't a lot, since you lose about .3v in transfer (so 5.0 is actually 4.7). Not enough to make a difference in heat, anyway.
Is there an ampere value listed after the output voltage? I know it should be 2.0 or 2.1 for the Samsung one. The ampere value determines charging rate on equal voltages, and so a 2.0A charger puts out twice the charge as a 1.0A charger. That's generally why one overheats when another doesn't.

Using chargers and batteries that are not specifically for Note 3 can void your warranty (and basically all the horror stories with S4 battery problems so far were from either a non-Samsung battery or a non-Samsung charger).
The Samsung USB3 cable has the extra thing with the extra pins for USB3 - I would suggest using that cable only with the Samsung charger OR with a PC when you need a USB3 connection. For everything else you can use a good USB2 cable (those are like 1-3 EUR, maybe cheaper in other parts of the world).
All that being said - the battery will last longer is you recharge it slower and if kept cooler.
The G2 seems to be capable of using Quick Charge 2.0, which is part of the Snapdragon 801 chipset. But with mine I got a basic AC wall charger, and if you read the (literally) microscopic text on it, it says it's putting out only 1.1 amps... which is well short of the at least 2 to 5 amps of many other chargers. So my questions are this:
1. Did anyone else get a higher capacity charger with their retail kit? Mine is a long rectangle bearing the LG logo.
2. If not, is this stock charger really not compatible with Quick Charge 2.0, or am I just reading the fine print wrong?
I've been researching this further, and it may be that LG intentionally shipped a low amperage charger. Because the battery is not user-serviceable, it would behoove them to use a slower charger, since ultra-fast charging harmful to the its life and capacity. The intricacies of rechargeable batteries are many, but the excess heat generated during charging degrades a Li-Ion pack pretty quickly, among other things.
Still, based on the assumption that the stock charger is truly 1.1A, I just bought a QC2 charger -- when I'm out in the field, I don't have time to sit and wait for something to charge at an outlet. I also bought a 10000mAh external battery with a solar panel. The rate at which LP eats juice is no joke.
@voxluna the g2 is using an Snapdragon 800 chipset and it might be capable of doing it but I don't know about it. But the micro usb port also doesn't support it as the additional pins were highlikely for slimport. Also using quickcharge on a device like this is highly risky as the device might not handle it too well. If the stock drains too much I suggest to find the cause of the problem and kill it or use an good custom rom with an good kernel and remove apps you aren't using. Goodluck.

I will dig into the QC2 wiring plan, just out of curiosity. I am confused as to whether an extra USB 3.0 port/pins are necessary (like on the Note 3) or not. Though I believe that plugging a phone into a higher amperage device is not supposed to be harmful. It's too late to cancel the Amazon order, so we'll see.
What I don't know is if my 1.1A charger is what's standard with a retail G2. The reason I asked if anyone else got a different charger is that this phone was a refurb I got from T-Mobile. For example, it came with a cable that I don't think is OEM LG, because it doesn't work with ADB. OTOH, it is possible they just don't implement QC2, like most models don't have the FM radio capability. But, the radio is omitted because carriers don't want it competing with music downloads; as for faster charging, I can't think of a good reason you wouldn't offer that feature.
@wulsic After a little digging, it appears you don't need any extra pins like on the Note 3; a sync+charge cable will suffice. And that makes sense, because the QC2 standard applies all the way from Snapdragon 200s to 8xx. Nonetheless, so far I haven't seen any documentation saying the G2 compatible with 2.0 -- the single LG device listed by Qualcomm is a G4. Crazy, really.
That still leaves QC 1.0, but I have yet find anything that shows the G2 (however, Qualcomm's listing is dated from before the phone came out, so it's not definitive). It may also be that a plain 2A charger, which I do have, can do the job faster than this LG 1.1A. I'll have to do some accurate testing to quantify a difference.
Further research: I came across this thread, a post in which seems to indicate that the G2 can do fast charging. However, I'm having a problem with the current not showing up properly in monitoring apps, which is confounding this entire process.
Method:
First I used my phone until the battery was below 15% in order to get a better picture of what the charging would look like over almost a full battery cycle. I did not start at the same battery percentage for each test because I did not find any benefit to doing so. I original did this for uniformity, but it did not make a difference after trying it using the more accurate equipment.
I then cleared my history in the Battery Monitor Pro Widget (BMW Pro) recording app which was used to log the battery [mV], battery temperature [F], time, and battery percentage changes. Once this was done I plugged in my USB Power Monitor, turned airplane mode on, removed the case, and let the phone charge. I started logging the data via my power monitor once the phone showed it was charging. From this point onward I let the phone charge without interrupting it until it reached 100%, then I let it charge for another 10-60 minutes to see if it was still drawing power from each charger. Once all of this was done, I exported my data collected from BMW Pro, emailed it to myself, and pasted it along with the USB Power Monitor data into an Excel spreadsheet. All of the data was then delimited to separate the clusters of data due to the way they were recorded, and subsequently graphed. The USB Power Monitor recorded data points every 0.36 seconds, while the BMW Pro took recordings every 5 seconds because I was having issues with the “real-time” recording option in the app working correctly.
All of the data was then graphed into the nice figures you will see below; each color reflects the same variable across all of the graphs to make reading them easier. I included a legend at the top of each set of graphs which should also help make it easier to read the data.
The most interesting part of this test is how cool the S7 Edge stays while charging, and the very marginal difference in overall charging time between QC 2.0/1.0. A 15-minute gap is marginal at best given the ‘big improvements’ Qualcomm claimed when launching the newer standards.
When conducting the wireless charging tests I think there is some error in the Samsung Fast Wireless charging data, so I plan on redoing it at some point. I already redid the Choetech one because it has a similar strangely long, but now it seems more in line with what I initially found before using the newer testing equipment.
I wanted to also quickly point out that both my HTC 10 and S7 Edge keep pulling current even after the phones show they are 100% charged. I’m not talking about a tiny amount; they both pulled ~1-5W+ after hitting 100% battery which is A LOT considering they are reporting to be fully charged. I verified this using 3 multimeters just to be sure. It appears as if Qualcomm, or the OEM’s are falsely reporting when the phone is actually charged, or there’s some other shady things going on here.
Another thing I wanted to mention is how the S7 Edge is so consistent in the way it charges the battery. It could be due to the lower rates Samsung uses (9V/1.67A max which is 15.03W) vs the HTC 10’s up to 18W that I’ve seen it pull. Just take a look at how the S7 Edge charges using QC 2.0 compared to the HTC 10 with lower temperatures, similar times, and a much more consistent overall charging curve.
If you look at the Tronsmart & Choetech QC2.0 tests, then you might notice the large difference between the two. The Tronsmart charger has a harder time holding onto the proper voltages, therefore it bounces around more from ~8.92V-9.03V (a 0.11V change) while the Choetech one ranges from 9.077V-9.092 which is a significantly smaller 0.015V range. The power control chip is responsible for controlling these voltages, and clearly the Choetech one has a better chip in it. This is especially important for external battery packs where efficiency really matters due to the limited amount of power they can store.
Equipment:
These tests were conducted using a series of different chargers. The same brand was used for both Quick Charge 2.0/3.0 tests to minimize experimental error; This trend remained the same was also done for the wireless charging tests

very good stuff!
maybe you could also record the heat at the hottest spot of the phone during charging? I think qc3 has the same charge rate but its able to change voltage to reduce creating waste heat compared to qc2.0.
my main concern with the s7 is the battery life, i know it won't last me a full 18hr day so i really need a portable fast qc2 charger that is pocketable, so maybe 5000mah, but have not seen such a small qc charger tho

I don't have a thermal camera, or way to do that otherwise I gladly would. I can recommend a small 6000mah external battery pack if you want; Ill do a quick write up too (if you need one). The Samsung charger stayed at 9V the whole time per my multimeter's reading it just dropped go .5A near the end.

Thank you, I will add in a standard wireless charger test (since my free Samsung one is enroute), and I can also get their fast charger too. I believe Samsung's fast wireless charger is only 7W so it would be slower than the Choetech one but it never hurts to see how fast it is.

@Pilz yes pls let me know of a qc2.0 small portable charger I think a quick 30mins charge to add 50% battery life mid day will be the best ease-of-use solution for me.
with the heat measurement, I'll be happy with your commercial grade temperature sensor that the great designer created for you, your fingers or better yet, the inside of your wrist.
preferably touching the same area on the phone every time and grading something like 1-5 hot/comfort levels maybe? just suggesting, no pressure

I'll look into some methods to measure the heat easily while they're charging. I'm conducting the standard wireless charger test using my free Samsung wireless charger right now QC 2.0 chargers the fastest when you start at a very low battery percentage, so ideally you can achieve the results posted, but ambient temperature, starting % etc contribute to whether or not that's attainable. It's still a good estimate for 30 minutes of charging +/- 5% for other factors. The phone also chargers slower when the screen is in. The rate would go from 9V/1.67A to 9V/1.10A with the screen on. It was very consistent when I turned the screen on and off during the test.

i actually won't care about heat issues while charging this time round, it'll be like my moto defy, i just run it under cold water after a fast hot charge, wont be using the s7 for many years so not worried about moisture build up.
i have ordered a magnet micro usb cable that says its rated for 2.4A charging so hopefully it'll allow easy qc2.0 charging, no need to plug in, it magnetically snaps on and off.
i think the best charge setup would be a 30mins quick charge (magnet) on the office desk than a 60mins wireless qi charge, carried in your pocket type situation.

Did you by chance order the Znaps? I backed them ages ago for both the Type-C and micro USB connectors. If I'm lucky I might eventually maybe sometime before I die receive them. I don't expect much from a kickstarter campaign that's been delayed this much. I'm finishing up the standard Qi/PMA charging test. It shouldn't matter the standard it's using but if it's important the Samsung wireless charger is actually PMA.

Yes it doesn't matter becuase the phone is only rated for 15.03W so it can't use more than that no matter the charging method. See screenshot below:

@Pilz yeah sure, it should arrive in a couple of weeks. i hate plugging in as well, even with the usb type c, its reversible but finding the port isn't always easy, they should have made the port surface like a cone or funnel so your guided into the port more easily.
the use of the magnet is awesome, Sony's external side charging pins have been around for ages, its really the charging current and quality of the copper that im worried about.

I never knew that plugging in a micro USB cable was so difficult. It could be one of those things that once you try a better alternative (type c maybe?) makes you ask how you lived without it, but I don't see what the fuss is about just yet.
I've used wireless chargers for years (way back in the NExus 5 days even) including in the car. Any word on fast wireless charging and heat? I'm worried about it pumping a ton of heat on to the back of the phone especially for extended periods such as overnight.

Micro USB is just more of a hassle becusse usually you need to angle it while inserting it into the phone. Type-C is nice becuase there no worrying about how I need to orient a cable when I'm half awake plugging my phone in. It's hard to understand why its nice until you use it everyday.
I haven't been able to measure the heat yet, but the phone is cooler using the 10W wireless fast charger than it is using QC 2.0. The phone isn't hot to the touch but it is warm using the fast wireless charger. I'll try to download a battery monitoring app that measures battery temp while it's charging. This method won't be as accurate as physically measuring it, but it should still give a good indication of the temperature.
Edit: I tested the temperature using GSAM battery montior via the fast wireless charger fro ~6% charge (28-34%) and the temperature rose 6 [F], the I let the phone cool and tested QC 2.0. The phone was charger for 6% to keep things cosnistent with a temperature change of 5[F]. I would need to find a way to more accurately measure these values because that quick test doesn't really mean anything at this point.

It's just a QC 2.0 charger from what I can tell. I have a battery pack that will charge using QC 2.0 so I can test it using my multimeter
