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)

Sorry if this has been asked before but I could not find anything!
I have problems with charging while using copilot and spotify!
I have a 1A car charger but it still drains the battery!
Also I have noticed that using the hdmi while playing games or watching movies with the original charger also drains battery instead of charging!
Does anyone know a solution to this, or am I the only one with this problem?

Its been covered in many threads, just search. The battery driver limits charge current to 650 mA in sourcce code, and the device can easily pull more than 650 mA doing many things like navigation or browsing etc.
So there's nothing you can do except someone compiling a new kernel with charge current raised.
I have lately experience on this issue.
I wanted a full day working device at my holidays, so I bought this battery pack from amazon: TeckNet Dual-Port iEP380 5000mAh 1.5Amp Output Universal USB Battery Pack (you may search it at amazon)
I thought that 5000mah capacity with 1A output is pretty enough!
Guess what: just browsing on internet (wifi) the phone's battery still drains while charging it from 1A USB port !! (using 1m long cable usb to microusb).
The phone must be in standby in order to charge it. ! UNBELIEVABLE !
Have anyone else experienced same issues with an external battery pack?
Any updates on this? Can it be fixed, or is there a reason why samsung has capped it to 750 mah?
I really hope it's not because of overheating or something like that!?

experiencing the same issue here as well... no solution online :\
I'm still searching for a powerful external battery
Nice phone, love the screen size and quality, but it seems it needs a plutonium rather than a Li-Ion battery.
Pretty much the same with mine but I was using Papago X5 on the go
Got SONY ERICSSON AN400 from ebay and my phone now charges with sygic running.
I was using samsung charger earlier and battery was draining while using sat nav apps
I am using the cardle in the link below. I would recommend both items as they are great quality and does the job well

While traveling I was using the gps (coPilot) with my bluetooth on, (just for calls) and was getting low on battery!
So... Naturally I plugged in the charger! Guess what! Battery drained nonetheless!
Has anyone else seen this? I have the screen brightness to the lowest setting... But to no avail!
I apologize if it's been covered before, but just looking to see if anyone else had this issue and any suggestions on making that battery not run down while plugged in!
Thanks everyone! Oh, and yes I have a second battery for these occasions!
Sent from my GT-N7000 using XDA App
Yes. covered before and many people see this. May be worth tying a 1amp or higher charger.
Also, if the phone gets too hot, it will stop charging.
I have the same thing... Its just don't charge however it maintain the battery at whatever level it was.. This is simply fixed by getting a higher amp charger
Thanks everyone will get a higher amp charger...

my official samsung charger that came with it has decided to pack in after a month of use, it no longer charges at the rate it used to of about 24% an hour and im lucky to get about 5% an hour now. I've tried my old hd2 charger (same 5v 1a output) and it charges without any issues

I got a 1A car charger with my mount which works ok (cheapo chinese says 1A). I think any car charger with a USB slot which says 'Ipad' would work better, IIRC the ipad needs ~2.2A so it would have plenty of juice.
I've got various car chargers, one at 850mA, one at 1A and one at 2.1A. None of them charge the Note while using sat nav (Copilot) even using night mode (dark backgrounds to maps) and dimming the backlight in between junctions. I've tried the USB lead that came with the Note and a lead from another phone. No improvement.
The phone shows Charging AC because I have the central pins shorted on the chargers, but even that is not enough. I'm thinking the only solution is to buy a proper Samsung charger, which might have some other trick up its sleeve for getting the Note to draw sufficient current.
I have just switched from using co pilot to another satnav app and the phone now charges faster. I knew co pilot was juice hungry. ...

My nexus 7 has been plugged in since 7 hours and still is just 70 % . using official asus wall charger rated 2.1 A . stock rom rooted device
Problem has been persisting since many days now . usually charges at this rate only ! While at 4.1 it used to be fine but now at 4.2.2 charges this slowly . please help..!
Here you go.
Please correct me if I'm wrong... I've had a quick look through a few of those threads and it seems as if there is no real solution? The charger that the tablet comes with takes many hours to charge the device fully?
Ridiculous! I hate that while I am using the tablet when its charging the battery still goes down (despite being plugged in)!

- you could have a bad battery
- you could have a bad charger
- you could have a bad cable
- you could have a variable amount of power drawn by an active device - which depends on what apps you have installed, your screen settings, kernels used etc cetera. (read : VARIABLE)
- you could be trying to charge the device via a USB port, which provides only 500mA of current - less power than the device uses in certain screen-on scenarios (esp. the 3G model)
Until you run tests which are meant to discriminate between these different scenarios, you will be just wandering around in the dark.
So try this - run the battery down through normal usage (not too far though) - say to 10%.
Then, turn the tablet off (not just the screen, I mean powered completely off).
Then charge it (on the 2A AC charger!) for about 75 minutes. Boot it up and see what the battery charge state is. Then, power it off completely again and charge it more (on the 2A AC charger!) for another 75 minutes. The first 75 minutes should bring it to somewhere around 50% charge, and the 2nd should be enough to bring it to 100% charge.
My (December '12) N7 charges from about 4% to 100% in 150 minutes (2.5 hrs) when it is on the A/C charger. That seems pretty reasonable, as 4.325 A-h / 2.5 hrs = 1.73 Amps.
By the same simple maths, a 500-mA current limit (e.g. USB hub/computer port) should take 8.7 hours to charge the N7 - even when it is completely turned off! And if you are using the device in this scenario, it might not charge at all!
This will at least tell you if there is a problem with the battery, charger, or cable. If it takes too long to charge when there's no software running, then the problem can not be software, right? (There's no software running with the device powered off.)
If it turns out that the battery/charger/cable seems OK in the above test, then the next thing to do is to determine what you have done to the stock configuration (in the way of adding apps, whatever). It's easy to say "4.2.x did this to me" or "4.1.x was so much better", but there does not seem to really be any compelling evidence coming from a majority of users that this is true.
I don't deny that people experience battery troubles; otoh, I'd wager that the root-cause of 95% of the trouble falls into two basic classes: defective hardware (incl. worn-out batteries and/or loose battery terminals), and user-caused software additions/changes.
good luck
I've had experience with 3 models that all three had power issues. Reconnecting the battery cable solved it for me, but in my case the N7 went 'dead' on me, didnt notice slow charging times. Disconnecting the battery cable for 30s then reconnecting and powering up solved the problem for me. Left me thinking their battery hardware assembly is very flawed. Or my local store has had a bad batch.
I found this movie helpful with the unhooking of the connector (at around 3:30)

My nexus device has stock ROM (not rooted) so I hope its a charger issue. Then the issue will go away quickly by replacing the charger.

similar observations while charging till 100% ..
It turns out that the charger may be faulty . I'll have try out other chargers. The problem is that I am here in india and made my relative bring it for me from the U.S. . I can't find any trusted chargers here . I'll try charging it with the other Sony charger I have (rated at 850 mah ) and compare the relative results . Thanks for the info anyways !

850 mA is going to charge pretty slowly also. Appearances (simple maths, A-h = Amps * hours) are that to get a 2.5-hour charge (4% to 100%) you are going to need a 2000 mA (2 A) charger.
As I said before, not accounting for losses the 4.325 A-h capacity of the battery works out to 1.73 Amps for 150 minutes. But probably due to losses the current is in fact higher - perhaps very close to the 2A limit of the US OEM A/C charger.
good luck
AW: nexus 7 charging awfully slowly !
This could be the solution:
It seems that the charger marked as 2amp is only 1amp: see this[first result googling <nexus7 battery charge slow>]:

I use an OEM charger - no problems.
I suppose that Asus could be multi-sourcing them from a variety of suppliers though, and that could account for different experience.
(Either that or something worse - funny business in Asus' supply chain or in the retail sales chain. There seems to no limit the amount of counterfeit electronics from the pacific rim and batteries & charger hardware seem like a likely place for that kind of activity).

Hi,
My Note 2 charging has become drastically slow in the recent times. Initially, when i checked the charging current using the GCC app (galaxy charging current), it showed me 1800 and now it never goes beyond 1000 and most of the times, it's between 800-900.
I have tried doing a factory reset and the problem still occurs.
Any clue on how to increase the charging capacity?
The reason I want the phone to charge at its max capacity is because I travel a lot and I do not get a lot of time to charge my phone and with its current state, I barely get 10 percent charge in 15-20 mins...
Please advice...

Correct guys, the included cable in the package will only give you around 800-1000MA. I have read a thread about this here so what I did I swap my white cable to a different one (original cable of Note 1) and the charging capacity of my note 2 is now 1800MA.

The cable does seem to degrade over time .Mine would even seem to get loose much easier than before. It happened to me. I ended up buying a heavy duty cable from Amazon that makes a secure and tight connection to the phone and charging has become so much faster now.
use perseus kernel and go to power then ignore unstable power, try, it may work

with perseus (with the same hardware) it works perfectly.
