battery taking to long to charge

hi i recently got a xda exec cheap from a charity shop as it had no charger ive got a charger that fits and seems to charge it but i left it on for 7 hours last nite and it only charged 70% i tried using a usb cable from an old nokia ngage and it charges it aswell but at the same speed does anyone know if this is a common fault that could be sorted with a new battery ect? Thanks for looking.

I would recommend to find someone lend you an original one (I mean the same charge amps and so on)
USB charging is not the more recommenden (Don´t know why)
If same problem continues then yes buy a new battery
In the Universal Wiki, there is a section related to battery problems with some solutions, you can also try one of those
Good luck,

Car charger problems

I use TomTom on my Touch HD with a car charger.
The first charger I used was fine but since I lost it I cannot find a charger that works properly... At first I thought I was just using faulty charger's but as I have now tried 3 different ones I am beggining to wonder if the problem is with my HD!
The funny thing is that on both the main screen and in TomTom it is showing the status as 'charging'... even the light on the top of the phone is lit to show it is charging but the battery level is still going down all the time!
The only thing I can think of is that maybe the chargers I am using now are not as powerful as the first one I used? Or are all car chargers standard?
Either that or my HD is broken!
Can anyone please help me find a solution?
Ps. The phone still charges fine through both a wall plug socket and a USB connected to a PC.

The car charger I use I bought for my old Tytn 2 (original HTC one), works great for the HD and Diamond, even when the battery was at about 20% left on the HD, TomTom 7 running, screen brightness max, the battery was almost fully charged within an 1hr.
Think it's rated at 1amp, you might want to check the power rating on yours, anything under 1amp and it's really going struggle to charge while using it.

Unfortunately its not printed on any of my chargers what amp they are... I actually thought they were all the same amp but if some are more powerful than others this could be my problem.
What does concern me however is that even when the HD is switched off it is still not charging (even though the light at the top of the phone shows it should be!)

There are plenty of tools around (HTC's battery.exe, acbpowermonitor, battlog, powerguard, etc...) that can show you charge/discharge current. If your car charger gives you less than the unit is consuming, battery will not be able to charge.

I had this problem and found it was because I was charging through the usb socket on the stereo which always worked on Polaris but not with Blackstone. If I charge from the cig lighter socket it works good.

link the charger to the main battery under the bonet and you will recieve a quicker phone charge, usually a full battery charge will take 24 hours, link it up to your main battery and a full charge will be done ina matter of minutes, its genius

First I used my original HTCTyTn carcharger by trial. But he has not
enough power to charge and run TomTom at the same time!
So, i bought this new one (more powerfull) for the Touch HD.

I bought a cheap and cheerful universal usb charger from tesco's for a couple quid. Works great and no problems with power whilst running TomTom

Hi, first post here and rather than start a similar thread so soon, i thought it best to post here.
Is it possible for car chargers to over-charge the device? I bought a cheap and cheerful car charger off ebay but was a bit concerned some of them are listed as having overcharge protection and this one wasn't. Wouldn't normally be bothered but its a £550 handset!
Cheers!

When using phone heavily and charging battery drians.

Hey guys thought I would post here has anyone else expierence this before?
When charging in my car and using either gmaps with gps and listening to music with my g2 the battery drians even while charging!
Yesterday it screwed me over. I was going to a place I had never been and no matter what I tried it wouldn't boot any more. Even after plugging it in to the car charger.
The farthest I would get is that it boots into recovery I hit reboot now and it endlessly loops. Its weird. Is my battery bad?
Thanks!

Your battery is fine. I suggest you pull the battery out for a minute or 2 and put it back in
BUT
do not turn the phone on yet. let it charge for half and hour to an hour to give it some charge back and see what happens from there.

Pretty much agree with the above. Make sure you use the wall charger, not USB or the car charger, as those supply lower voltage (EDIT: current or mA, thats the term/units I should have said, per below). Let the phone charge for a long time, maybe overnight, and see what happens.
I've never tried using GPS and playing music at the same time (at least not for any significant length of time). What do you have your screen brightness set at? Since the screen is always on when using Maps/Navigation, turning it down may have a big impact on battery drain, and might result in the charging rate being greater than the drain rate.

I bought the official HTC car usb adaptor for this very reason. Most car adaptors only output between about 300 to 500mA which is less than the battery drain when you play music, use gps and have 3g activated. The HTC adaptor outputs 1000mA and is the fastest car charger I have found. It is as fast as the Nokia N86 home charger I have. Buy one and you won't be dissapointed. It comes with a coiled usb lead in the pack but I use mine with the retractable usb lead that came with my powertraveller.

USB supplies only 500mA and car chargers often only supply 1000mA as mentioned. This might not be enough to cover everything =/
My car charger (the official HTC Nexus One car dock) does 2000mA though so it's great =)

Great info. I didn't realize the HTC car charger was that much better than others.

Ah ok this has to be it! Yes I imagine between taxing the cpu, generating heat, 3g, gps, and the screen on with music playing would drain faster than a regular usb can keep up with! Thanks guys. I will be finding a better car adapter! Anyone have any links of where they went?

I purchased the Motorola Car Charger from the thread below. Did some research on it, and it is rated to put out 950mah. Not quite as much as the stock HTC car charger, but its only $5 if you follow the link from the thread.
http://forum.xda-developers.com/showthread.php?t=819465&highlight=car+charger
I don't use my phone nearly as heavily as you do in the car, only for GPS directions when I need them. But it works great when I need a quick charge. Drove to work last night (about 15 minutes) and it took me from 22% - 34%. Enough to make it through the evening shift!

battery drain with car usb and gps

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.
http://www.nextag.com/Sony-Ericsson-AN400-Compact-853915153/specs-html
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)

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..

Chargers

Any risk in using a different charger than the original samsung one to charge the sgs2?
I use a combination of blackberry charger at work, universal micro usb charger downstairs at home, universal car charger and official charger upstairs.
Any concerns with this?

I've been doing that for ages. I use the droid, SE x10 and iPhone chargers with no issue.
As always YMMV

I am using htc's charger which has a higher rating than samsung charger. No problem at all...

I use a Sony charger to charge my S2 , I have not even removed the Samsung one from the box , As long as you use a branded charger will be fine.

I've tried to use Nokia's 1200 mA charger, It did charge the phone but whenever i connected that charger the phone would slow down terribly. So, whatever you use, try to keep it around Samsung's charger's 700 mA.

Ive found that the standard charger is rubbish! I had my galaxy s 4 month and it broke, my wifes galaxy 3 did same and now i dont even bother with the one out the box, just use the usb cable and the adapter i got with my tab.

Absolutely right...my phone is about 1 month old..and the official samsung charger is already broken..not charging anymore..i guess there is an internal wire breakage at the flexible point of the charger becoz when i shake the wire at that point it starts charging intermittently..

Same here. I tried all sorts to get it to work with no joy. I now have 3 duff samsung chargers that are potentially a fire hazard if left plugged in! Tempted to email samsung and raise this concern.

At home I use a Lenmar AC-to-USB 1A charger I picked up at Fry's for around $10; in the car I use a 1A Cygnett 12V-to-USB charger, also from Fry's. Both charge the device at least as well as the OEM AC charger; the car charger appears to charge the SGS2 even when I'm running CoPilot Live.

I use the iGO charge anywhere.
It's a tad pricey, but since the GS2 battery life isn't great (my only complaint on the phone), the charger is great for it since it has an internal battery that charges up when you put it in an outlet so you can charge the phone without needing an outlet. Great for in school or walking around, just put it in my bag and press the button and it charges.

I'm using my BlackBerry charger with no issues, I just do it for convenience as the charging time is the same as the standard charger.

Cheers for the replies, you have put my worried little mind at ease!

+1 .Just used the charger from a different brand and no bad feelings while using it

well, i just emailed samsung raising my concerns regarding the faulty chargers... see what they come back with....

Guys have you noticed any change in response when we plug in another charger?
I have been using the HTC charger, 200 mA (input), Output 5V --> 1A.
Whenever i connect my phone to charge and try to work on it, i see my screen lag terribly. Haven't tried it with the supplied charger though due to the low voltage that came with it.
I know i would be wrong, but wanted to check with the experts on this forum...

200ma is way low, less than half the 500 ma usb standard. Get a new charger. Most of the chargers you are going to see will be 500 ma I would go with double that.

Some (bad?) chargers will disable touchscreen
I have a couple of usb-chargers off ebay and they give some trouble.
When connected, the touchscreen will not work anymore.
This is mentioned in the manual btw.
Guess the SII is a little sensitive.

Yeah, ebay chargers are a crapshoot. Head to walmart or similar and read the power specs, get something that puts out 5v at 1A LPS. This will charge much faster than the often usb based standard 500 mA chargers and the battery will not be harmed at that charging level which is what many stock HTC chargers put out nowdays. Do not get anything less than 500mA, this is the usb standard and works but will be slower to charge. El Cheapo no name chargers on ebay and such may have the spec but may or may not actually put out the juice. You can usually tell this because the phone will have problems like the ones mentioned right here. The stock charger does not put out any special juice, juice is juice. If a charger puts out to spec the phone will work while charging.
