[Q] Faster Charger? Please advise

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

Well I am using the USB in the pc and the battery has not moved once notch ... has to be the rom (gingerbread) or the combnation of usb cord and charger.

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?

Skyrocket can't function as GPS Navigator?

This weekend I went on a trip and decided to try out using my Skyrocket as a GPS navigator using Google Navigation. I had my phone mounted and plugged in the whole time for about a 2 hour trip. The screen was on the whole time usually at high brightness (it would dim every once in a while.) When I removed my phone from the mount I noticed the power was down to the low 60's, which struck me as slightly odd since it was plugged into the charger the whole time. The next day I tried to use it as a GPS system again, but even as it was plugged in, this time I literally saw the battery gauge draining. When I turned off navigation and the screen the phone would finally start charging.
Is this a common thing or is there an issue with my phone or possibly my charger? Does doing all those things really drain the battery faster than it can charge it? One last note is that I was not in an LTE area during this, or at least not the whole time (I only noticed it was LTE at one time during the trip.) When I saw my battery draining in front of me I definitely was not in an LTE area.

Might be your charger. I'm having no problems using it as my primary driving, hiking and general outdoor GPS unit. When on car charger, it's charging faster then it drains.

I believe my charger is an old Motorola car charger that came with my wife's old dumbphone. It's actually not even a Micro-USB charger, but rather a Mini-USB with an adapter.
This may be a dumb question, but the actual charging port shouldn't be the issue right? I'm assuming those are always the same standard.

Check the car charger amperage output. I have an old car charger to USB that only puts out 750mA and another thats puts out 1A. Anything less than 1A with the navigation running (which means the screen and GPS stay on, of course), and it'll still drain the battery (and even at 1A it may still drain).
I've been putting off getting a powerful enough car charger myself. You'll need one that puts out 1-2A I would think. Most of the common ones off the shelf are 1A or less, and I've heard that some chargers reported max output is not as good as reported.

i second this...my phone won't even charge on some wall chargers, unless 700mAh or higher. let alone do any battery heavy functions like GPS. get something with at least 1a output

I'll try swapping the chargers. I have an overpriced AT&T one that I got for free that is collecting dust.

If the charger has 1A output then it should be OK

I'm having the same problem with my Skyrocket and cheapy charger that I bought at Fry's. Use the navigation with screen on and my battery is less than when I plugged it in.
Going to buy this combo 2A and 1A charger.

When I was looking for a more powerful option, I saw that one on Amazon as well. My only hesitation at buying it was why it was so much cheaper than all comparable options at local stores, or even online...I've heard that the cheapie chargers may not actually output what they say...though for $4 plus shipping, I guess it's not much of a gamble. Let us know how it performs!
P.S.-Pulled up the reviews...not too many positive ones (though 1 or 2 were good): http://www.amazon.com/GTMax-2-Port-...iewpoints=1&sortBy=bySubmissionDateDescending

Its actually more than just the charger output that is a problem. If the center two pins on the USB connection aren't shorted, the phone will treat it as a USB connection to a computer, not an AC connection from the wall, and only draw a max 500mah. I had bought a 1amp and 2 amp charger for my car and would get the same results as the 500. I started to think it was my car limiting my output!
But I then found an article detailing this problem that I've since lost the link to, but the method worked. Pop open the charger and solder the 2 middle connectors together and all is good.
I don't know why the charger manufacturers don't know this... Or maybe this phone is doing something new? Maybe someone makes a USB-> micro USB with the center pair shorted in cable?

Just Google "Solder USB Car Charger" and you'll find plenty of tutorials about how to do that. Personally I'd rather just buy one that out of the box works.

Tried out my AT&T charger (which can be found here) and it worked perfectly. Set up the GPS and everything and now it will charge even while doing all that stuff. Thanks for the help

I have the same issue with my SkyRocket. LTE makes no difference. If I'm using Google Navigation or Waze and the Screen is on my charger/phone can't keep up with the battery drain. If I turn the screen off and keep the GPS app running the battery either doesn't drain or doesn't drain as fast.
I've checked my car charger and it's one of those dual usb ones, with a 1 amp port and a 2.1 amp port. It has no indication of which port is which, so I don't know what port I'm using at any particular time. I've tried both and the effects are the same.
Regardless, when the phone is plugged in to that charger the phone reports that it's an AC charger. Supposedly that means I'm getting at least 1 amp, right? So why is 1 amp not enough?
I don't like the car charger you guys suggested because it has the curly cord. I'd rather use a car charger that doesn't come with a cable so I can plug in my own usb cable.
Any suggestions?

Discharging while using Navigation

Hey Guys,
So I was recently on a trip this weekend and was using Navigation on my Nexus 5 for a 4 hour drive. I had noticed though after a short while that while I had my Nexus 5 plugged into a charger it was still continuing to drain battery.
With my Galaxy Nexus in the past I was able to run Navigation / Music / Etc.. all whilst still charging so it came as a disappointment when I saw this.
I made sure that I was charging on (AC) mode and it still continued to fall, albeit a little slower than (USB) mode though. When I went to the battery usage navigation had taken up about 59% of the battery drain, I was surprised because I though it would have been the screen but that was only like 14% of the battery drain.
Anyone else run into this issue?

Check the Amp output on the charger. Anything less than 1A will not charge the phone while in use.
I had the exact opposite issue with my G-Nex, the "rapid" charger I was using only output 550mAh as opposed to the 1A that is required to charge while in use. I don't believe it is an issue with the phone, it's probably just the charger. $10 to $20 will get you a nice, reliable one with the proper output, and possibly an additional USB port.
Hopefully this helps

Don't buy cheap car chargers, just not enough power. I use a Verizon car charger that has an extra USB port for charging another device and it charges while the device is in use.

Thanks for the input guys, unfortunately the charger was 1 amp that I was using. I do have another car charger that I use and none of them are the cheap USB ones. I guess I'll have to do some more testing with the other car charger that I have.
I was just mainly concerned, not if there was something wrong with the phone, but with the fact that even when charging in AC it wouldn't keep up with navigation's wear on the battery usage.

Thought I would update to confirm that my Galaxy Nexus car dock charger charged it extremely well after testing while navigating.
Definitely was the other one I was using.

When you switched chargers did you happen to also use a different cable? I couldn't get any of three different chargers that I tried to keep up with the GPS battery drain. Then I realized I was using the same cable with all 3 chargers. The problem was that the cable kept the phone in DC charging mode at nothing more than 0.5 amps. I bought this fast charging cable on Amazon and now I actually gain battery percentage even while using my GPS full time.

[Q] Charging Too Slow Now

I have had my Verizon Galaxy S4 since February of this year. I've been using the stock Samsung AC charger that came with it. It's always charged the phone pretty fast if I wasn't using the phone. It would charge about 15% in 20 minutes. Now it's only charging about 3 or 4% in 20 or 30 minutes. Now I didn't do anything different to my phone. I've been on this same ROM for over a month and this is just now a problem in the last week. My wife has the exact phone and charger that I have and when I use her charger it charges just as rapidly as mine used to, so I know it's not the usb port on my phone itself. I haven't dropped or damaged my charger at all in any way either.
Does anyone have any ideas about why this is happening?

If it charges fast on you wife's charger you've pretty much answered your own question.
Try using her cable with your charger, if it still charges slow then get a new charger.

I had the same problem too ! Did a full battery reset and everything is going good now !
You have to charge it for 12 hours and drain your battery until your phone don't boot. Charge it and here you are !

Yeah these devices act funky every blue moon. My wifes didn't even recognize ANY oem charger for a week. Only detected others as USB devices causing slow charge rate. Removing dust, component cleaner, fresh install, all did no good. Eventually it just resolved the issue itself. All chargers work normally again.

change the usb cables
I also had the same problem before. I'd been using the original charger and usb cable and noticed that charging takes a lot of time than normal.
I found that it's on the usb cable. I accidentally found it when I used gsam battery monitor. It displays the current being received by your phone when charging. Using the original usb cable, it only gets around 600mah. I tried another usb cable (from a previous Samsung device) and now my phone gets 1,900mah (closed to the charger output of 2,000 mah).
Every since I changed the usb cable, my charging is fast now. Hope this helps.

I would try a new cable and Charger that is rated 2.1 amps or better if will be charged real quick

I noticed that using the Pure Nexus rom my charging time became significantly faster. In fact I can get a full charge from nearly dead in just over an hour. This is using the charger and cable that came with the phone.

MT tenso

How do you make full battery reset?

The charging rate is based on the output rating of the charger, which is determined by the resistance value between the Data+ and Data- USB pins. If you use a cheap cable with high(er) internal cabling resistance, that will throw off the detected charger output capacity rating, and knock you down to a lower charging current and longer charging time.
Also, one time, even with the original charger and original cable, I couldn't charge at anything more than the default USB 500mA. I ended up having to power off the phone, and power it on again, which fixed the charging current and speed problem.

Install this app & check if it is getting charged at max current; anything less than 1200 mA when screen on & 1900 mA when screen off, you need to change your cable or charger

How to measure charging rate even when the screen is off on S8 plus ?

Hi, I got the S8 plus verizon version.
I suspect I have fast charging issue. The phone doesn't seem to do fast charge all the time even when the screen is off.
I want to know if there is an app that can measure the "overall" charging rate from start to finish when the screen is off. I tried Ampere, it is good app, but it only shows the "current" rate, which very often is around 500mA to 700mA on average on Samsung original charger. Yes, it does occusionally go up to 900mA or 1020 mA. But never over, on samsung original charger. It is normal? I remember I used the Anker charger with QC, it shows it went up to 1680 mA ... However, when I do it now, it does not. It caps on 1020 mA.
Sometime even worst if I a QC car charger, at around 300mA .
When the screen is off, there is no way for me to see the charging rate. If QC is not working, is the phone has some minor defect? I should sent it for repair ?
Please let me know if I have other ways to measure it.
(Thanks in advance.)
Note:. Yes, I also experience some screen shut off or no powering on issue like some members here.

Please let me know if I have other ways to measure it.
(Thanks in advance.)
Note:. Yes, I also experience some screen shut off or no powering on issue like some members here.

Although not an app, this works great as it shows the charging voltage as well as the current.

AccuBattery Settings > Notification Priority > Minimum. It will still show in the pull down notification list but the battery % status bar indicator will be removed.
You could probably also disable it entirely via phone settings > notifications.

I think you are measuring with usb meter but im measuring with Galaxy Current Charge app & it shows MA per rate current. Can you tell why I'm not getti g stable MA rate, it constantly chaging.
