When the droid charge is fully charged it puts an alert on the screen saying so and saying to disconnect it from the charger... obviously when you are sleeping you won't see this message... so is it okay to keep the charger plugged in for like 12 hours? can the phone OVERcharge itself and hurt the battery life?
I have killed the battery and fully charged it and over charged on purposed and haven't seen this message.

I get the message too every time charge reaches 100%
No. Samsung Androids will stop charging at 100% (that's when the message pops) and won't start again until the battery has dropped to 95%.
Getting rid of the nag will be one of the first mods to drop.
yup message definately shows... but once the message shows does it automatically STOP accepting the charge or does it OVER charge itself if left plugged in?
Please reread my post.
just saw it now.. sorry..
how are you certain of this?
also, is it okay to use a Blackberry Bold AC charger on the Samsung Droid Charge? the output voltage is the same but the output Amps are slightly different.. the Droid Charger is 1,000 millamps output.. the blackberry charger is 700 miliamps output

You might be ok using the BB charger, but I don't know. It would be safer to use one rated for 1000mA or greater. I haven't looked to see what the charging rate is yet on the Charge, but on the Fascinate it was only 600mA max.

Because every other Samsung phone works like this.
Also, they auto-limit their current intake from charging cables (there was a *lot* of experimenting with these in the Vibrant and Captivate forums last year). So it's safe -- but no faster -- to use a higher-current charger. Lower-current should be fine, too -- they'll just take longer.
The main problem with using BB chargers:
(1) the micro-USB tip might not go in all the way. Other Galaxy S models (dunno about the Charge specifically) have a particularly recessed port that's finicky with many non-Samsung cables/chargers.
(2) the phone might not detect it as a wall charger. I believe Galaxy S phones detect to see if the data lines on USB are shorted together, which some but not all non-Samsung chargers do in the same way. If it doesn't detect as a wall unit, it will charge but the current intake will be much more restricted on the phone end (so it will take longer).
It may not give you the full 1a from the wall, but this cheap charger works great on older Galaxy S models.
thanks for the info.. well I guess I will have to figure out what the Samsung Droid Charge actually PULLS for the charge...
since the BB Charger is putting out 5 volts and 700 miliamps.. if the Samsung needs more than 700 miliamps then it may detect as a USB charger and just charge slower.. which really doesn't matter to me since it will be plugged in for about 8 hours straight while I'm sleeping... I just wanted to make sure I could NOT overcharge it and hurt something inside the phone.
I just found that if you go into the phone status screen under the settings and you plug it in via either USB or AC Charger it will say 'Charging USB' or 'Charging AC' respectively.. just tested that with a Blackberry Bold ac charger it it says 'Charging AC' so I guess the Droid Charge is pulling LESS than 700 milamps because that's what the BB Bold charger is outputting..
The Charge charges at 475mA via wireless charging or USB (computer) connection, and 800mA via wall charger. See here - lines 3125 to 3150.

Most devices work this way. USB power via your computer can't safely sustain the charge rate that a wall outlet can. To avoid issues, they just set it up to charge slower over the USB connection compared to via a wall charger.
Long story short: if the phone manufacturer has any common sense they know to stop the charging at 100%, let it back off to about 90% and trickle it. That's how most new smartphones work.

Nope, the phone stops charging when the battery reaches target voltage and shuts the port off completely if the battery gets over a certain temperature.
Hey,
I noticed that the droid charge has a bigger battery but it take a lifetime to charge.. is there a better charger I can get other than the one that came stock with the phone? Please let me know. I would really appreciate it.
The stock actually charges fast compared to USB...use a higher amperage charger with the stock usb cord (so it doesn't limit to 500ma). I use my Galaxy Tab charger...works great

PC USB ports do not do a good job charging phones. they don't have a lot of power going to them. In addition, if you're using your phone while its charging from your computer you will not likely see it charging at all since all the power its getting is going to whatever it is your doing.
The same is true of car chargers. I had mine plugged in in the car for 45 minutes using the GPS. It charged 2%. The point is, the only real effective way to charge your phone is by using a regular outlet.

Correct about the pc charging; it only runs at .5 amps (500 ma) while the stock charger has 1 amp. However, the car charger really depends on what kind you're using. I use a 2A and it charges fine.

ok cool. so i could just look for a charger will higher voltage being delivered. I hope i get the right one that is compatible to the droid charge. Dont wanna burn the battery out etc
No, not voltage. Amperage. Big difference. Just get a charger with a USB port and a high amperage...I don't think you'll find a higher amp charger specifically compatible with the Charge.

ok thanks!
You need a charger that won't be seen as a USB connection on the phone. If the phone thinks that it is plugged into your computer, it will charge at roughly half the rate of the wall charger. Wall charger will charge at ~700mA I believe, and the USB/Computer connection will charge at ~400mA. You can find the actual numbers in the power regulator driver in the kernel source though.
I have a motorola 950 amp car charger I got off amazon for $5. It works well but if the screen is full bright and I'm running navagation I have seen the battery level drop. To keep up you need a 1+amp charger. That being said the harder you charge the batteries the quicker they will wear out.

This is pretty interesting. I'm not a phone dev or an electrician, but I assume these mA numbers are something that are 1) lower than what is actually safe and 2) might be able to be tweaked by a dev with nothing better to do. Not that you are even close to falling in that category, but I think many users would be quite interested in being able to get more charge out of shorter durations, albeit at the risk of burning out their phones.
Search for my responses here on charging cables... Sorry but I'm at 35,000 feet in an airliner and can't search very well to include a link. The "magic" to allow a charge current greater than 500ma is either in the stock AC charger or in a "charge only" cable. The data wires to the phone have to be shorted otherwise the phone will think that it is plugged into a computer and will start USB services and will limit the charging current. Cheapest to fabricate your own adapter!

So it wont harm my battery at all to use my galaxy tab charger on my phone? What about in the long run will it degrade faster?
I think the phone has intelligent charging logic (like the newest iphones) so if you keep it cool it will take care of itself. YMMV however!

You could have a 10 amp charger, and if it is picked up as a computer/usb connection, the phone is going to pull the same amount of current as it would just plugging it in to your computer. The same goes for car and wall chargers that get picked up as a computer/usb connection. It doesn't matter what charge rate the charger supports, the phone is going to pull the same current as it is regulated to via the kernel. The only time it won't pull the full charge current it is setup to pull is if you have a charger that is rated for a slower charge rate than what the phone wants AND it won't allow charging above its stated capacity (any good charger should do this).
I have looked around (not much though) at how to make the charge rate faster before, but couldn't see how to do anything besides make the phone charge as fast over USB as it can via the wall charger. However, from what I have read, Li Ion batteries do better if they receive a slower charge to full and will not die as fast compared to being rapidly charged.

Slow charging is true to some extent, but there is no need to charge our battery's under 1.5amp.
And shorting the two data pins on the USB doesn't work it looks for a specific resistance, I saw the ohm load somewhere, but now of course I can't find it lol..
When I get really bored tonight I will edit this and figure it out. But yeah our phones can easily pull 800ma or more with full screen brightness and maxed out processor. So that would result in no charging at all on some chargers. I use a 2a wall charger that came with my evo and it charges very very quickly. Never more than 1 hour to full charge unless I am gaming on it while it charges lol. This is using the cord that came with the phone of course so that it knows it isn't in a data enabled usb slot.

In electronics, when given a voltage source (as opposed to a current source) the Voltage is set to a fixed value. That is what our wall USB outlets are. Voltage sources
Think of Voltage like a waterfall. The water is always dropping from the same height. The voltage is always set to the same value.
The mA rating (the current) is determined by how much juice the phone can pull. Just because a charger is capable of supplying more current (say 1 or 2 amps), it doesn't mean that the Droid is going to draw that much current. However, if the droid is capable of pulling more current, it will benefit by charging faster.
Does that help at all?
*edit* Dang it. Didn't scroll down enough to see that imnuts posted already. Oh well, screw it. I'm leaving my post. lol. People who don't know about Voltage and Amperage need to hear the waterfall example at some point in their lives.

Did you read anything I posted The phone is only going to pull a set charge rate, depending on what type of connection it sees. It doesn't care what power rating the connection has, it will pull as much power as it can, up to the limit defined in the power regulator of the kernel. You can use a 1A charger, or a 2A charger, doesn't matter, the phone is still only going to pull a set. The phone will pull 475mA via USB connection (your computer) or 800mA via an AC adapter (wall charger). Unless you figure out how to hack the battery driver to allow a faster charge, those are the two rates you get, regardless of how much power the wall charger can supply.

A charger is going to provide a set voltage (5V I believe) and that is the only constant in the charging process for what is going into the phone. The amperage is going to be determined by the phone or the wall charger. The only time the wall charger will be the limiting part in charging is if its circuitry is setup to cut off charging over a certain level, and if it is rated for a lower charging rate, odds are, it probably won't cut it off and instead produce a fire hazard.
Something else people don't realize is that the charging rate isn't just bad for the battery if you charge to fast, pulling to much power in to charge the battery, especially while using the phone, creates a heat problem as well. While the phone will shut itself down before any major damage can occur, why would you even want to create a situation that could potentially damage the phone hardware?

How can you use a USB Port to charge? It is not possible.

Depends on the amount of current your USB port can supply. I have some on my desktop that can go 1A that will charge it painfully slowly. My laptops won't give more than 500mA and never show charging when Tablet is connected

You are totally rigth, it's impossible ... with your computer.
With mine i can charge to 100% in about 12 hours.
It's (very) long but it (really) works.
Many quality USB wall chargers will put out 5V 1A. USB on a compiuter usually puts out around 5V .5A. Closer to the low end if your on a laptop, higher if your using a desktop with good power managment.
The tablet is set to charge either from 5V or 15V. Basically, if you charge from the supplied charger it will charge at 15V. If you charge with 5V it will take aprox 3x as long. If you have fewer amps then thats less current and less overall power getting to the tablet, meaning a longer charge time.
You CAN charge the tablet off USB from your comptuer, tho it can be slow. I have also seen intense games that cause the tablet to use more power than a 5V charger can supply so depending what your doing you may not be able to charge the tablet connected only to USB.
I searched through some of the threads and I didn't see one directly related to my question so here it goes. I have been unable to get my tablet and or dock to charge with any other charger other then the one it came with. I'ver tried a samsun tablet charger, an 8w usb charger, other misc wall blocks etc. Will our tablet only charge with the asus charger? Any thought's or ideas on this would be great.

According to some it is possible to use a USB 5V charger to charge but you need the patience of Job and have it shut down. The simplest answer is that this tablet cannot be charged from ANY USB 5V power source.
The tablet charges at 12V 1.2A. The ASUS Charger is wired in such a way that when using the supplied cable it charges the tablet with 12V @ 1.2 A. When any other USB cable is used the charger will output 5V so that it can be used to charged other devices.
The only other source of chargers is from eBay. Just make sure you buy one that puts out 12Volts with a minimum of 1.2Amps.
There are other answers to this same question just maybe not the way you posed it!

Yes, the tablet (but not the dock) will charge from a 5V USB port, but it will be *very* slow (a few % per hour), and the tablet must be in standby or off.

Yes the original is 15V, it does actually switch to 5V if a non transformer USB device is connected. I'll add that a lot of the cheap eBay chargers output 11V to 12V which is why we have so many issues with the device trying to figure out what it is connected to.... imo.
A regular USB charger is 5V.
The tablet starts detecting a charge at 12V.
The original charger is 15V.
It CAN be charged from 5V, but you have to shut it down and it charges at 3-5% an hour. This isn't "some" mentioning it; it's in the bloody manual.
@sbdags If the cheap chargers indeed charge at between 11V and 12V, that explains the constant beeping people experience whilst using them. It keeps varying between "Charging" and "Not Charging".
So basically it sounds like the best way to charge is from the original charger/cable that came with the unit. This is no biggie. I was just trying to understand why a 8v battery back wasn't charging the tablet, but it wasn't idle, i had it on. So if I wanted to use that I would need to power off the device and it will essentially trickle charge. I don't see to many 15v usb car chargers on the market, though I haven't done extensive research. Thanks for the input.
It does charge (slowly) when on and idle - I regularly charge it overnight hooked up to my PC.

It probably depends on the amount of amps the charger can push. The stock charger is about 1200 amp (or 6 watts), which is likely the limit the phone can pull. Are you using the stock charger or something else?
I've never timed how long it takes myself. I just plug in when I go to bed and unplug when I wake up. (Actually, these days I usually use wireless charging overnight.)
Are you using a wall charger or another device's usb port? USB is limited to 500mA for USB 2.0 (900mA for USB 3.0 ports.) Also a cheap 28 gauge USB cable will only put out 500Ma even if you plug it into the stock wall charger.
