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!

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)

nexus S didnt have such a problems. it's only around how samsung managed chipset.
I ll try to set cpu downclock while temperature goes over 40..
I'm looking to get an adapter for the car to plug-in my TF on roadtrips.
I sincerely doubt it pulls much power, but I'd like to know so I can buy the smallest possible DC / AC adapter possible.
Does anyone know how many watts (@ what amps) the TF pulls while running? While charging?
I was looking at:
http://www.amazon.com/Duracell-813-0291-07-Pocket-Source-Inverter/dp/B000U0M7PG/ref=pd_cp_e_2
Which I would imagine should cover it, but if I could get an even smaller one (since this is the most power hungry device I travel with...well maybe my thunderbolt while running 4G is, but I'm less worried about that) I will search that out instead. Thanks!
why don't just buy a phone car charger that uses USB? The USB end of your Transformer cable would plug into the charger. You can pick one up online for a couple of bucks as opposed to $30. Just about anyone will work.
No, you should NOT take any usb car charger, because most of them have not enough output.
The original has up to 15V and 1.2A.
I used one of a mobile phone with just 0.4A, nothing happens.
One with 5V and 1.0A need about 3 days to fully charge.
I suggest that you go over this thread:

Hey everyone,
Before my Transformer arrived at my door-step...I started reading around a bit more about spare chargers and such - and came across a few threads that people had had trouble charging their TF101 because the AC Adaptor was fried/dead/whatever.
I own the B60 version and all seemed to be going well until late today. I plugged in my charger as per usual...and no charging icon. I did a few plug ins/outs and swapping the polarity of the plug to no avail. I also tried an iPad 10W charger and that did nothing; proving to me that only the supplied charger or a 12V molex rail can charge the thing.
I then thought of any changes I had done to my TF101 over the course of the last 24 hours. I remembered. I had installed Clemsyn's kernel v9 on the Revolver 2.5 ROM. So...I thought about reverting to Netformer 1.6 kernel I was using before.
After flashing, it started to charge again. (Note: I did reboot the TF101 a few times before this to see if it was a Honeycomb issue).
This is a theory anyway....if the chargers are failing on stock ROMs and kernels...well that's ASUS' fault.
Hoped I helped anyone.
i don't know about this. I got a b60 also. The charger didn't work the first night I got the transformer. Stock rrom stock everything. I played around with the charger and it worked again. Now sometimes it works, sometimes it doesn't. Im on custom rom now and its still the same.

I was completely stock when my charger just stopped charging both the dock and the tablet. A few days later it started charging only the tablet and only doing that occasionally. It never did charge the dock again. It was the impetus I needed to finally RMA everything back to Asus for which I am waiting its return. It seems to me that this charger just can not be trusted and that is a big problem with a proprietary charger!

How many chargers have you owned, and how many of them have died? If it's a sample size of one, it's pretty-much meaningless. You only hear complaints from people who have a problem, after all.
Personally, I've used three chargers (mine, my wife's, my fathers) with three tablets and three docks, and none have had problems as yet (several months).
I have a B4O TF (fantastic BTW) and my charger died ...stock rom etc.
sent to asus...week later they still can't find my RMA (and I thought Dells customer service was bad)
I had already bought a charger for spare so I can wait
I bought a 5mm DC Female Barrel to USB Female cable - EBAY $2.99 and I'm always looking at chargers for it when I see one... Bought a I home 120V AC to 15VDC adapter at goodwill this weekend for 1.99 total cost of my new charger (others gonna stay in the drawer) 5 bucks and some change

i had the same problem with my charger month back when i got my pad. i called asus. it is a known problem. they sent me a new /replcemnt part for the charger. no hassles . ive been fine since
I experienced this same thing last night. I had flashed to Clemsyn's kernel Elite v12a kernel. I did a reboot however and charging resumed. I was having a hard time connecting to the computer as well. Perhaps, the kernel or settings still thought that the Transformer was connected to a PC because it will not charge from a PC unless the screen is off. There must be some script that is being interfered with here. Your theory may have some traction.
I was rooted when mine decided it didn't want to charge anymore, I had only had it for 5 weeks. I unrooted and even back to stock it still didn't want to charge. I sent it back to them and they fixed it after a week. Everything's been good so far.
My charger was working intermittently and I was near the point of returning the TF w/ dock or buying another charger. Then I tried running the charger thru a car power converter in my car and it seems that did the trick. Now it charges everytime, its worth the try.

okay so im not the only person here. my charger just stop charging yesterder. never rooted, always stock rom. i did factory reset, and still no good. now it only charges very slow, no charging icon showed. the cable is good, i can still connect to laptop.
The real question is: Is it the pad or the adapter? Because if it's the pad, that sucks big-time, if it's the adapter it is irritating but not a real problem, you could charge it via USB on your laptop/PC
I finally contacted Asus regarding to the faulty charger. And they told me to return the whole thing to the my retailer, because im still within the 30 day return period.

Charging via a PC is very limited. It will be very slow if it works at all. The charger provides higher voltage (15 vs 5) and higher current (1.2 vs. 0.5 amps). The charger and pad also expect the current on non standard pins association with USB 3 connectors.

Gotta be the adapter. I tried everything to get it working again, I noticed that when the screen was off, and I plugged it in, nothing would happen. But If I plugged it in to a smaller charge adapter, it would show the screen (as if something were connected), but not charge. So I tried my friends charger and it instantly started charging. However, After I charged it, I went back to my old charger, and it worked again. WEIRD! I have a backup adapter now just in case it happens again. Same thing happen in the past, It wouldnt charge (and I didnt have my friends), so I let it die, and charged it with my smaller adapter (which took like 1-2 hours to get 7%). Then I plugged it in again to my old adapter, and it charged it. It's almost like the charger reads it as full, and wont allow it to charge anymore. Then when some other adapter start charging, then it realizes it does need battery. No idea. Just my 2 cents.
Clemson Blades v.17 fixed it for me
Charging required a reboot after a certain amount of uptime. But, I also use Battery Monitor Widget's circle battery status icon. What was wierd is that sometimes the ASUS battery icon wouldn't show charging, but the circle battery status icon would.
Anyway, everything works for me now with Clemson Blades v.17. He specifically added in usb forced charging with v.17.
I saw the same problem with both ac adapter and computer's usb, but it was fine for a while after reboot but would stop working again after a while.

If anyone did a search, you would know that this is a common problem.
The trick is to unplug it for 5 or so minutes and it'll work again. Also, the writing on the plug should be facing up.
can i use any charger that can fit into my kindlle fire?
i have a charger of LG optimus one and it fits exactly.
i cant find shops selling kindle fire charger here in the philippines.
the original has 1.8A - would try to get one that has around this value
with a charger under 1A i'm pretty shure you'll get charging problems or at least it lasts very long
basically you can use every usb charger ...
Yes you can as long as a charger has equivalent current as the original charger.

Any USB charger will work, but one with less current won't charge as fast.

No... I got a charger off ebay and it said it was for the Kindle Fire, but it was only 1000 ma. and I had all kind of problems, There are several threads on this already..Get one at least 1.8 amps and you'll be ok..
The Kindle Fire will recharge from a powered USB hub or computer just fine, and that's only 500 mA. The USB spec doesn't allow for anything greater, so you may run into incompatibilities with other chargers since compatibility is the main reason we have specs. Hopefully manufacturers are talking to each other about how to make fast chargers, but, given Houndog101's experience, it doesn't seem like that's always the case.
The Kindle has a 16.3 W*h battery, so you can calculate how long it'll take to charge given any current (5V * current = Watts), if you account for the loss due to the Kindle being on at the time. A standard USB port is going to take at least 7 hours to fully recharge the Kindle, and probably more like 10+ if WiFi is on. So I'd definitely go for a 1.8 A charger, and hope for the best. Don't spend too much since it might not work unless it's specifically made for the Kindle.
Belkin F8Z630 charger
I've bought several of the Belkin F8Z630 chargers and been very pleased with them. Not cheap, but they deliver a solid 2.1 A at 5 Vdc, they can handle any input 100-240 Vac (basically worldwide usage), and they have a nice rotating plug feature that is handy in some tight spots. Works great for charging the KF quickly.
I found one in my car from an LG that chargers it just fine, and in a timely manner.

I usually stick with the OEM charger and cable with devices but since the Shield K1 doesn't ship with either I was using another cable I had around.
I noticed the tablet was discharging while in use even on a 2A charger. I tested the charger's power consumption with a wattmeter and found it was only running about 1A. The cable was inadequate. Trying different cables was an illuminating experience.
I found some informative sites about this. Here are my favorites.

Those are some really informative links. Thanks for that.
Noticed that too! Bought some days ago an longer USB cable (3m) but used it with the original charger. During gaming battery drops, with original cable it doesn't load but also doesn't drop, strange....
yeah, also bought some generic cable (1.5m long) but im using the oem charger/adaptor of nvidia shield tablet, since i broke the tip (micro usb port) of the oem cable.. there is a noticeable slowness in charging.. so, with regards to charging time, it's not always the adaptor itself, you can also consider the cable..
I had similar experiences using other devices.
I recall reading recently that there are estimates that *more than* 50% of USB cable manufactuered in 2014 were fakes. The trend was not going down - who knows, it might be 60% in 2016 :|

Ampere doesn't work with the shield tablet.
I tested with the shield tablet k1, marshmallow update. Just always showed 0mah. I put up a review explaining it, but the developer simply flagged the device as incompatible rather than trying to fix it.
I have a usb detector device from amazon tho, and I get 1.2 to 1.8 amps with if I use my galaxy s5s charger. Oddly out of the 4 different ones i have, thats the fastest. I read it supports quick charge 2.0 so I gota fancy charger with that that does supports it, 2.1 amps.. But it actually charges much slower then the samsung one - Yet chargers my actual S5 at the same rate, so I just swapped the cables and leave it like that.
PS: Was charging MEGA SLOW no matter what before I did this fix:
chmod a-x logd in terminal emulator.
(This also greatly enhanced battery life)
Also charges much slower with screen on.
