Battery takes long to charge.

Been charging my phone for more than 3-4 hours now and it's still not fully charged. Its connected to my PC thru the issued USB. I don't think that's normal. Wondering if you guys are having this issue?

I've noticed that too. Don't know if the wall charger will do better. Probably not, but it might deliver more power. I'll give it a try tonight

It's a big battery, but it does take quite a long time on the wall charger, and quite a long time plus forever via USB.

A big battery but drains in a day with normal use. I though Super AMOLED was suppose to be very power conservative. I see on the battery status that the display is the main source of use.

In the Android 1Ghz world, the longevity of the Captivate battery is pretty darn good.
Just don't forget you're in the new and shiny "I just got this ****, check it out!" phase. That phase has been scientifically proven to shorten battery life by up to 80% for the first few days/weeks.

if there was a quote of the week this would be it. i use my phone so much the first few weeks.

I do admit I've been playing with it so much, I just thought it would surprise me by having enough juice left by the end of the day. I just hope it charges faster than 3-5 hours.

try charging it in one of the back usb ports if your using one in the front
sometimes the front puts out less power

I agree, the battery does take an abnormally long time to charge. It sure is fun discharging it though!

why not just use a wall charger it would be waay faster wouldnt it

Wall charger is slow for me.
From my Samsung Captivate

I've found that USB charging from either the back of a computer or a "higher output" port on a laptop charges faster for me at least on my iPhone 3G.
Wall charging has always been faster for previous phones as well. Strange that this isn't the case for the Captivate

That was the question around the office today. How's the battery life? TBH, I don't know. It's only been 24+ hours since I got the phone. I've enabled WiFi, Bluetooth, and GPS tonight to see how the battery drains.

On the many previous smartphones that I have had, I've found that the wall charger gives the best charge. Charging on from a USB port can take much longer.
NOTE: You can only mount the SD card properly, if you plug it into a native USB port (the back of your pc). Can it be that native USB voltage requirement?

Charging on your PC's usb is slower than wall charging. It takes a better half of a day to charge my Cowon S9 via PC, and 1-2 hours via wall charger.

Ive also heard that it takes time to "break in" these batteries. After a week or two see if you are having the same charge times.

I've not had this problem as charging time surprised me with how quick it was. I went from 30% to full in a couple of hours. I was not expecting a message to unplug the charger when the battery got full. I am used to plugging in the charger and taking it off only when I am leaving the house. Id it a problem leaving this phone on charge? I think not but then why the message?

My phone was at 7percent at 11am and by the tIME 2am rolled around it was only at 92. 3 hours and still not a full charge? I think there is something wrong. Lol

I noticed that too. i was like WHY ISNT IT MOUNTING! but then i swapped to a native port on the rear and voila!

I have noticed that mine charges fine with the wall mount and slower through PC. I actually tested GPS and Nav for 4 hours while driving from out of town using the car charger. The car charger couldn't keep up and the battery was still slowly discharging.
-J Chao

On wall charger mine is taking about 7 hours to charge from 0% - 100%, and with pretty normal use it's down to 0% again in about 5-6 hours. Swapped my battery for a new one and still getting the same results. I'd like to swap out my device but there aren't any available at AT&T.

Extremely slow charging

Has anyone had a problem with extremely slow charging? I would plug my phone in and wake up 6 hours later and the phone is still not charged. It's even worse now with the extended battery. 7 hours worth of charging and I'm only at 85%. I'm rooted and using the de-bloat rom without the kernel, but it was like this even before the root. Has anyone else encountered this strange issue. I have been using the stock HTC charger.

mine charges in a couple hours using the wall charger and wifi hotspot. In the car or via computer USB, it charges very slowly and if wifi hotspot is on, it loses charger over time.

I typically turn my phone off to charge; speeds things up 2-3 fold.

Mine doesn't even take an hour . Power it off and try it that way and see how long it takes.

damn mine charges super fast compared to my nexus s i had

If you have plug to the computer it might take longer but not 6 hours, on the wall it only takes like an hour or two to be fully charge.
If it's an issue just take it back and get another one.

Yeah I might have to return this phone. Do you think it matters whether I use the cable that came with the phone, or a regular usb cable to charge.

You need to look at the power ratings of the adapters you're using. This behemoth phone can receive 1000ma, while many car and home chargers (like Droid1) are only rated at 500ma. I'm still trying to figure out what the power draw is on the phone when just idling (battery monitor widget is hard to understand), but if the phone draws 250-500ma with regular usage, its going to lose charge plugged into USB (rated at 500ma per port) and running hotspot (drawing closer to 600ma). That's -100ma.
These numbers are guesstimates. I'm not sure if the cable itself can pose limitations, but would suspect that as long as there's no shorts in the wire, it would be able to handle any of the above currents.

yeah i find it impossible to charge the thing on USB, and it takes forever plugged into the wall with the charger it came with.
Had an evo, and it would almost full charge (from the time it said to plug it in, so 15%) in about an hour and a half. The thunderbolt seems to take 3 hours ish for me. I know I can turn the phone off, but since it usually charges over night its not a big deal, I just think it is interesting that it is so different.

yeah I'm one of the folks who charges FAST. It has really surprised me...I actually thought everyone was charging super fast until this thread.

+1 on looking at your adapter. Use the one that comes with the phone or make sure that it's rated at 1000mA/1A or more. I tried a MicroUSB adapter I had lying around that came with a bluetooth headset; turns out it only puts out 200mA, so the phone would take forever to charge on it.

with an output of 200mA I would be amazed if you could get this phone to charge at all, without having a custome kernel and underclocking the processor. If anything I would see it maybe staying same battery percentage.

Overall I feel this phone does charge really slow. It is way slow charging on a computer. I was charging it and just doing some light texting and after 4 hours the battery only went up by like 25%.
I have a second wall charger rated at 1000mAH, and after 30min it went up like 10%. This was with the phone off btw. With it on, but not in use, it went up like 4% over 30min. I'm kind of surprised how long it takes to charge. I've had no problems charging it at night. Plug it in before bed, and its full when I wake up. How does the 1400mAH battery size compare to other phones?
I did a little math too, the battery is a 5.18 W/hr battery. So with a 1AH charge at 5V, you'd expect the phone to charge in 2 hrs if only about 50% of the electricity is getting retained by the battery.

I've noticed that mine takes about 1hr 45ish mins to charge from completly dead. My Droid used to be an hour at the most.

i just checked on the adapter it came with, it's 200 mA...did people get better chargers than me or something? Mine takes forever to charge also...been stuck at 99% for 30 mins
EDIT: nvm, i was looking at input, not output...still isnt moving from 99% to 100% though

@lorijuan1024 im with you man the Nexus S took forever...... To charge

its impossible for me to charge it through the computer, it went up 5% over 3 hours, wasnt on hotspot, sending texts.

Mine charges fine on anything, I am using my old fascinate charger.

Charging speed seems to fluctuate for me... sometimes I get lucky and its fast. Other times, not so much.

[Q] LTE +Netflix+USB = Fail?

My charge is running stock Froyo with the latest version of Netflix and the rotation patch applied.
In my office here, I get LTE, so I enabled it, fire up Netflix, and connect with my USB cable (The cable is Samsung, leftover from my Epic) to my computer to keep it charged.
The battery still drains, and eventually it even overheated (said charging was paused because of battery temperature).
Anyone else experience anything similar? Any suggestions on how to fix?

First off, the Charge has a specific cable with a special connector pin that helps with flashing(among other things) and that might be your problem. Second, USB charging is much slower then direct wall socket charging, and third Netflix is a battery devouring MONSTER. I think one episode of Prison Break(42mins) drained about 10-20% battery. You can't out-charge Netflix with a USB charge, as for the overheating there's nothing you can do on stock, if you flash the PBJ OTB kernel you can underclock/volt to keep your battery cool, it still got slightly warm during netflix but everything else felt air conditioned. Sorry if I sound like an asshole, just read my post and I sounded like I was trying to prove a point lol. Just trying to help.

It's cool. I figured the Epic USB cable would work since it's an SGS phone, and I've used it to flash ROMs to that phone - and I definitely don't feel like shelling out to samsung for more special magical heavy duty usb cables. Maybe a powered USB hub would help. It seems it's heating up quite a bit just using Pandora, too. I'm wondering if it's a combination of volts/amps/whatever that it's trying to suck from the USB port, and maybe also my otterbox not allowing the heat to dissipate off of the back.

The otterbox will definitely hold in some heat. As for the powered usb hub, that won't do anything unfortunately. The max amount of power coming from a usb port is 500 mA and a wall charger (at least the one specified for the charge) shells out 1000 mA.

I did find a 12 adapter that puts out 1A. Not that has to do with anything on this topic.
OK, I am going back to work.

Charger getting hot | Controller for quake

Hi guys, I got 2 subject so I thought I'll just make one thread for this.
I'm from EU so I used my US charger with an other plug. Seemed to
work great, doesn't complain like it does with my HTC phone charger.
But now the charger gets pretty hot, along with the USBplug that is in the charger. Should I be worried? I would say its about 50-70celsius.
_______________________
So I got Quake from preware, but it doesn't work with touch only (even tho there r touch controls?) so Im wondering if its possible to get it working with this:
http://icontrolpad.com/
That would be nice with the snes emulator also so I might buy it, its very expensive tho but I like the oldschool'ness of it.

You're likely to burn it out if you keep using it, don't leave it on unattended.

Sure? Does your get hot?
The charger should handle ~220v as we got here. So I don't get why this shouldn't work.

Isnt there a way to find a compatible European charger without paying 30$ for the travel pack?

Pretty much any micro-USB charge will charge the Touchpad, it is just some will be quicker than others. I am charging from the USB port on my laptop at the moment and it has upped the charge by 8% in the last hour or so with the screen off.

Yeah but the normal one gives about 30% on that time. But as I said, it should work, no problem. I don't think its uncommon for it to get hot but I'm not sure tho

My official charger gets quite warm, together with the USB plug. Clearly that is the only device that will charge at full speed and without a warning on the screen. However, as I was trying to point out, you don't have to go down the official charger route if you are prepared to either accept the on-screen warning or a slower charge rate. The Blackberry Playbook charger gives 5V 2A and although it comes up with the on-screen warning charges almost as quickly as the official unit.

I bought one of these http://www.mymemory.co.uk/iPod---iP...s-USB-Charger-and-Socket-for-iPod_iPhone_iPad the other day, rated at 2.1 amps (though the unit shows 3 amps). I get the dire message about not enough voltage or current but it works fine and quickly. Obviously I don't use the supplied Apple cable...

Stock charger - charges slow and drops battery

Hello there,
I decided to open this thread as I've now had a bunch of issues with the stock charger that came with the device and it would be interesting to know if there's anyone else who's having this type of issues.
The exact issues that I've been having with the stock charger seems to be that the charger doesn't output enough of a amperage for the tablet to hold charge while in use, and even when it's not in use it takes almost 7-8 hours to charge from 50% up to 100%. It's as slow as if I would charge it from a regular USB port, if not, even slower and I don't really know why exactly this happens as it says that it's charging from AC adapter in settings.
To comfirm my issue was not related to the tablet itself, I used another charger that's rated at similar specs to the stock charger (2.1A) but with the same Micro-Usb cable that came with the tab. With that charger, it charged up from 50% extremely fast (around 1,5 hour) and I could even use the tablet while charging without any battery drops. So that comfirms two things, it's not related to the tablet or data cable but to the actual charger itself.
Anyone else that's been having this type of issues with the stock charger?

My tab needs max. about 3 hours to charge full and imo it's ok. Tried charging during Half Life2 gaming and can confirm that there's not a lot of charging going on, maybe 1or 2% in an hour. But that's ok for me, as long as it doesn't start to get emty while charging during gaming.

The charger is defective or don't bring enough power to the unit. I also get negative charge while playing high end games an also increase when i am, on Optimized mode. Many others has reported this situation on GeForce forums but nVidia is quiet about it.

I get negative charge even when doing basic tasks like listen to music or watch a video with the stock charger, so I guess my charger is faulty. I've already reported the issue to Amazon and they gave me a 50GBP partial refund (80 USD!) because of the faulty charger without having to ship anything back.
I just find it odd that theres many people that have the issue and nvidia doesn't seem to do anything about it either!

If i were you, i'll check with another charger doing normal stuff, if you still get negative charger maybe it could be your battery itself.

My guess is that a faulty cable or the charger itself is causing D+ and D- to not be shorted together by the charger, resulting in the tablet thinking it's charging from a USB port instead of a dedicated charger.
Does device status report charging state as Charging (USB) instead of Charging (AC)?
I admit I never even unwrapped the stock charger, I've got one of those nice Anker 40W 5-port chargers along with a bunch of 24/28AWG MicroUSB cables from Monoprice.

The charger appears as AC in settings, so it should be charging faster than it does.
I'm using a charger similar to what you use right now, a Dodocool 4 port charger that works great! However, I'm using the stock cable.

First make sure you are using stock charger and cable.
If you see discharge during non intensive activities you may have a defective charger. Nvidia has rma'd the charger by itself for people.

I have the same issue but my charging time is a bit better 3-4 hours. But what is really annoying that it makes a lot of electrical noise. I have a lot of things that I charge, but I have never heard this so load earlier. Its coming from the adapter, I can cleary hear from 3m. Anybody has similar issue? I try to record the sound, and send to nvidia. Maybe they will react.

I can confirm that this combo works a treat for my NST. I use it to simultaneously charge my G3, NST, N7 and some small LiPos. Fast charge.

Sorry to dig up this thread but I've had the same issue and i was WTF-ing like crazy until i switch the USB cable to a charging cable i got from a power bank... The charge time dropped from 6-7 hours to 2-3 hours. I'm not sure why, perhaps my cable is faulty or perhaps it was meant to charge like this, or perhaps it is supposed to be used to connect a controller only (both ends seem to have a controller icon on them)?

It's not due to the MicroUSB cable but due to a wallwart that's messing up the amperage I believe, as I've used the MicroUSB cable with other wallwarts and it charges normally then

You are correct. I charged the tablet at home 2 times this weekend and it's definitely an issue with the charger as it sometimes charges properly and sometimes it does not.

A bit hard to do since i got it from amazon.com when i was in the US (back in EU now) and there's no point in returning the tablet just for a semi faulty charger.

Contact amazon and tell them exactly about the issue, they'll compensate you for it probably. I got 50£ back from Amazon.co.uk for the broken charger, which is quite a bit of money.

Thanks for the tip, i'll give that a try

Well, same thing here. Just noticed it while using Skype. Battery dropped from 100% to 95% pretty quickly while charging.
I'm going to ask Amazon for another charger or compensation.

I have a 2.4A charger and still battery no good.
I lose around 2% per min of battery charge while idling with battery saving features on (2 cores shut off, CPU frequency set at 50% and Framerate locked at 30FPS) when ingame the battery drops 2-3 times faster. takes 2 hours to charge from 97% to 100% and 2 mins to lose that charge. I think I bought a Tablet that has a faulty battery as this is not acceptable. My tablet is unusable as the battery takes a couple of mins to lose 3% of charge and a couple of hours to regain the 3% charge only to lose that charge (and then some) when I try to use the tablet.
