Came from a TP2 and I could charge via USB at around 900 mA using fast charge driver.
Since I am a complete Android n00b, and an EVO n00b I have two questions.
1. Are there any apps out there that can show you how fast the battery is charging and discharging? I had one called Battery Monitor in WM, and I want an Android version of that.
2. It appears that USB charging is quite slow. Can anyone confirm the speed at which this phone charges via a USB port?
3. Is there a way to make this faster?
TIA!!

A 1. I don't believe there is one (someone correct me if wrong), but there are apps to monitor your battery percentage.
A 2. Not sure, shouldn't be too long, how long is it taking yours?
A 3. I don't believe so.

Thanks...Not sure how long it takes as I havent had the phone too long. I know while plugged into my computer last night it wouldn't charge very well.
Computers have much lower power than a wall socket. If you want to charge the EVO fast use the wall plug. Anyone who uses a Mac and the wired keyboard should know what I am talking about.

A USB port provides 500ma of power, you can get micro USB cable that will Y off and plug into two USB ports, providing 1000ma of power.

Every computer I owned charged my TP2 at around 800-900 mA as long as the fast charge driver was on the phone.
So I know for a fact that it's possible. It's limited by the phone, not the USB port. Appreciate the reply, but did you read Negrito's link?
And Negrito, I did search... This forum.... No hits. I see the link you provided was in the Hero forum. I didn't realize that the fast charge USB issue was affecting other Android phones as this is my first.

My bad broseph, totally forgot im still subscribed to Hero threads. I just switched to the Evo Launch day.
Its not really an issue per se as that's how all phones normally operate. On WinMo we just got spoiled my No2Chems hack. Anyone know if No2Chem made the jump to Android?
I have seen a lot of familiar names on the Evo forum, like OMJ, and Caulkin!!! I cant wait until someone comes up with an untethered root option and how to bypass the NAND cause I know the ROMs are just going to be simply amazing.
Was digging around in the custom menus, can't remember which one, but one of the ones that you type ##numbers# and enter your MSL and there was a check box for USB charging. Mine was unchecked for some reason. I left it alone but wonder if that makes a difference?
I've tested a few charging scenarios and can tell you that using a wall charger that outputs 1000 ma will help speed up the charge.
These from Monoprice work very well:
http://www.monoprice.com/products/product.asp?c_id=103&cp_id=10311&cs_id=1031106&p_id=6767&seq=1&format=2
want the same thing for the car?
try this one.
Here's the link to a micro usb cable at monoprice for $1.20.
There's a nice Rosewill 4 port charger, that will output 2000 ma IF you have only one device plugged in. With two devices plugged in, it falls back to 1000 ma (still really good). I have this in the kitchen for the kids to jack their various usb things in for charging.
The thing to remember is that the phone will pull as much as it can (most recent phones can pull between 750 and 1000 ma.) What will cause it to charge slower is not usually a software setting, it's having a port that will only put out 500 ma or less...which is what many computers output.
Sean
there is an option in settings /devolopment for usb charging doesnt ssy what it does though
I don't think mine has taken more than 4-5 hours to fully charge and signal strength isn't the greatest at my house so that probably has an impact on it as well... I've no idea if that's normal for a smartphone or if it's considered slow, I don't think my Sony Ericsson feature phone was any faster but the battery indicator on that thing was wildly inaccurate anyway.
My EVO seems to charge just as fast w/the included HTC adapter as with a generic Philips one I had, as well as one of those retractable cables. I was afraid that cable wouldn't be very well shielded and it wouldn't charge right but it seems fine, I'll only be using it when I travel anyway.

No one has seen nor heard from No2Chem in months... Some people think he may have died
I could charge my Touch Pro 2 in about an hour or two using a standard usb plug on any computer I owned.
Might I add the Touch Pro 2 and the EVO share the same identical battery. The EVO obviously draws more current..... I found while using my EVO while plugged into a computer, it barely charges at all. My guess is its discharging while charging at a very similar rate.
Contrary to what most of you are saying, the ma rating of the charger really makes no difference as the phone (and prior htc phones) will pull <500ma if they detect they are plugged into a computer or non-official charger and 1a if they detect an htc charger (which can even damage 500ma chargers). The way this is detected is through grounding of one of the microusb pins in the official charger (and indeed many generic chargers but not all will be detected this way). Absent this grounding (I forget which pin), it will charge at a slower speed. I know of cheap 500ma chargers which have been caused to smoke by attaching a cable with that grounding fooling the phone into thinking it is an oem charger. Many chargers labeled 1a will charge at the 500ma rate as well.
Also, modern computers are fully capable of outputting 1a of power through the usb port. While the spec indeed is 500ma, with a proper cable (or the fastcharge driver for windows mobile), you can force a 1a power draw without any issues. Cheap usb hubs or cheap usb power ports may run into issues.
I'd love to see a solution for android but I don't think one exists.
Actually the HTC battery Widget will show you if you are on AC (1A) or USB (500ma) charge. You can get this widget from the market (not sure why it is not included in the phone in the first place).
I think that the grounding pin is likely the trick and I will be searching the web to see if I can locate it. I have an older battery pack from APC that can output 1.6A but the only way to get the EVO to charge as if it was on "AC" is to use the HTC plug, and then quickly, before the charge light goes out switch to my alternate source. This seems to trick the EVO into thinking that it is still plugged in to the official charger.
This is of course trickier with my car charger, which has been very frustrating - using the phone for navigation and plugged in via usb usually has the battery draining rather than charging!
I wish there was an easy way to fix this, my old phones always attempted to pull as much current as they needed.
My friend uses a 2A charger for his HTC touch pro 2, and it uses the same battery as the EVO if u guys didnt know.
i havent tried it on my evo, but being its from htc too (and uses the same battery)... id expect it to work with that much current.
I currently use a 900mA one in my car, and i do notice that if i use something less than that i tend to get feedback from the audio jack that connects to my cassette player
Found a discussion on this on the android forums relating to the HTC Desire:
<Too new of a user, system won't let me post the link>
I opened a car charger and shorted pins 2 and 3, and the phone did show charging over AC (2 and 3 are the data pins, 1 & 2 are power). My multimeter was acting up, so I am not sure whether the EVO is actually pulling more current - it does appear to be charging faster.
If you try this make sure of 2 things:
1. You charger is capable of 1A.
2. If you choose to short the pins on a USB cable make sure this cable never gets plugged in to your PC.

For your Q #1 search the market for Battery Indicator, great simple app that gives you a battery percentage and how long you have been plugged in or unplugged.
Has anyone experimented with a greater than 700mA microUSB charger? The charging time with the stock unit is much too slow IMO.
I bought a 2A car charger and have had no problem
Sent from my... you know!
I have a 2A, 5v car charger, that works no worries. I needed the higher power charger to have the phone's BEAUTIFUL screen on with Sygic Navigation running while Im driving, and still have the phone charge.
Running it like this, it charges slowly, but doesnt get very hot and can be running the whole time.
I havent tried having it plugged in much without the screen on, but i reckon it would just charge faster without much fuss.
Cheers.
I'd like to know where you bought it from, guys...

Would you check the current the phone is drawing from your 2A charger?
Go to the file /sys/class/power_supply/battery/batt_chg_current and open it with Astro or some other file manager.
In the same location, the file charging_source gives the following values:
0 - no power source
1 - usb power source (with limited current per batt_chg_current)
2 - wall power source with higher current in batt_chg_current)
What is yours reporting when connected to the 2A, for both files?
Hi community,
I have a query I couldn't resolve on any ICS rom. For a number of weeks I was pretty sure it didn't charge when settled in a car dock. Lately it appeared in fact device is charged bit the ROM is unaware. It wouldn't show an icon nor show charging status on a lock screen. Also battery stats are unable to tell the phone has been charged.
I had a theory that car/lighter charger had too low power so I connected car dock to travel charged and got same result.
Same time desk dock works just perfect.
Anyone had same experience?

Not really a car dock, but I'm using a car charger bought for Samsung phones which is actually from energizer and works for just about anything usb. it plugs on the car lighter socket and has 2 usb outputs. My car supports 120w and the charger it good to up 1A so lack of power is never an issue. I just plug the phone's data cable there and the SGS charges normally. Using ics elite's 1.2 rom.
however, i do have your experience with some other (rather crappier, not even Android) Samsung phone. It appears connected and charging and it doesn't turn off if the battery is low if I'm phoning someone but as soon as i plug it out it didn't charge at all. My charger has a red light that turns on when it's charging something but it's not even on for this phone. Not really sure why this happens. The sgs works flawlessly though.

Been trying to find a convenient and affordable way to ensure I can charge my beloved S4 in my truck at a rate that can keep up with music streaming, navigation, and/or a dashcam app. It would be nice if it actually charged too, not just kept up.
So far, I have tried these chargers:
2.1A Output Dual USB Car Charger
1 Port USB Car Charger 2.1A
And this cable (note other lengths and right/left angles available):
Red Band Smartphone Quick Charge Cable
I can get just as fast a charging rate according to CurrentWidget as I can with the wall charger at home (1200mA).
Two problems.
One is I can not run Pandora and my Dash Cam App at the same time and still charge. Running the dashcam app alone, it still charges, but i need my music.
Two is how come I see people saying 1900mA? Is currentwidget lying to me? How come, even with the stock charger on an outlet I can't get over 1200mA?
Does anyone have any better suggestions for how to get the most out of car charging, or have I exhausted the best of the best?
P.S. I just ordered one of these to test out. Anyone have any experience with anything like this?
Okay so currently I use my genuine Samsung 2.0 MHL adapter for my car because I use the AppRadio 2 head unit in my car. I use the ARUnchained app with it and everything works great. However if I use a navigation app like Waze, my battery drains even though it states that it is charging. If i'm just listening to music without the phone constantly looking for my location then it will charge, but slowly. What really blows my mind is that if my phone is at 100% charge when I first plug it in and then use Waze, it will stay fully charged. I am using a Scosche car charger that puts out 2.4 amps per usb port. Also when I go into my battery settings it shows that the phone is being charged from (AC) instead of (USB). I have tried using various USB cables, MHL adapters, and even different car chargers(the one I currently use puts out the most power so I'm sticking with it). My question is, how can I get my phone to charge when using a battery draining app like Waze? It absolutely blows my mind that if you start with a full charge it will stay charged but you plug it in with anything less than 100% and it will drain.
I noticedon my phone that when navigation software being used my charger cannot keep up with battery drain untill i lover screen brightnes
