Powering using USB 5v/gnd via the battery pins. - HTC EVO 3D

Hey all i am wondering if it will do just fine if i hook up the USB 5v/gnd to the pins on the back where the battery pins would go?
On the battery itself it says:
(4 pins )
HTML:
[][][][]
- +
However, the battery is rated 3.8vdc so i wanted to make sure it wouldn't blow something giving it 5v in that area.
And i am guessing the first 3 pins are all ground pins? And the last (4th) pin is the positive?

you will not burn it, because battery on 100% is 4,3 V. But i think it will not work, cause battery has electronics on 3rd and 4th pins

You cannot just apply current to the battery directly. It has to go through the charging circuitry of the phone first. Otherwise, you will blow up the battery.

I'm not also keeping the battery there. There will be no battery hooked up at the same time.

well, as i said it will not damage the phone, but phone will not work. Try, if you have time
i know it worked on sonyericsson T100

Just use a miniUSB cable and plug it into your computer. Any USB wall charger should work. I've used iPhone USB chragers with a miniUSB cable, Nikon camera chargers, as well as a Motorola one. You just need to plug it into any USB port either on a wall or on your computer. Leave the device off while it charges overnight.
Problem with charged
I use both ways but no result , phone indicates to charged but battery not charging.Charger is original and consists of two parts: the charger and mini usb cable .When i run it sometimes on the displays show this message : The charging current is not enough for device power consumption.Please shut down unused applications , or switch to AC adapter. And I do not use any applications. I tried to load phone in the off position , indicates that the charger is ON but the battery is not charging .Please help if someone has the same problem

Try it with a different miniUSB cable. If you don't have one handy, miniUSB cables go for pennies on Amazon or eBay. You can find them in retail stores for about 10 dollars or so as well. If the cable isn't the problem, then it is either a problem with the charge port on the device, or the battery. It's far cheaper to trouble shoot the cable, so let's just start with that.
Sound like the charger is insufficient power, even though it says 1A. Try charging from a computer USB port and see if it charges. HTC don't list TP2 as suitable for this charger.
I am also facing same problem. LED shows charging but phone does not charge. And when I insert charger "USB TO PC" page shows up, Like I have connected the phone to PC.
Please Help...
I just had an issue charging which turned out to be an easy fix.
The led would come on and the icon would show charging but it wasn't increasing the battery %. Then I would get a message about the power not being enough and to plug it into a charger. I tried several chargers and was getting the same thing happening. I blew a few puffs into the charging port which looked clean and it was still happening. I wiggled the cable/plug in the port and occassionally the charging light would go on and off. The charging led even started to go on and off with the phone just sitting still on my table. I feared that my charging port had gone bad so I ordered 2 spare batteries and battery charger from ebay for $10 (works well and battery life good).
While waiting for the ebay purchase to arrive I did some reading up and saw that pins could be bent etc. In my fustration I used a pair of tweezers to gently scrape the charging port pins/contacts (in a straight direction). Then I used an old toothbrush and firmly brushed out the usb port - a whole bunch of lint and stuff come out of the port even though it had previously looked clean.
I plugged in my charger and bingo! My charging issue was gone.

That was the biggest problem with MiniUSB was the width and height of those ports. It's a haven for stray dust and dirt. They need to be brushed out every so often, especially when you just drop it in you pocket.
hi buy and it schould work
buy a new charging cable

I was facing the same charging problem and was looking for a solution. And i found this forum and read it and did the same thing and my problem is fix.. I can charge my mobile now. Thanks a lot for the great help.

All of these dumb charges, ie bricks in the wall, use the unused USB pins to communicate how much power they can provide. There are some resistors they put on the D-/D+ to say this is a 700ma charger or whatever. Trouble is that there are limited standards on these resistors so it's more than possible that a phone will charge but not enter high current charging when attached to a new brick in the wall. The cables however are more universal.

HTC Car charger 1amp vs generic 2.1amp car charger

When ever I drive, I have my phone hooked up to my Escort Red Line radar detector and my car's stereo via bluetooth (both). In order for me to use the radar detector effective, I need to have GPS and Blueooth enabled. This is a HUGE SUPER OMG battery drainer for my amaze. 20 minutes drive kills about 35% of the phone's power. My radar detector offers a slot to charge my phone BUT it still drains, not enough juice flowing in. Someone said it is because it's probably a .5amp.
So I am running a extension from the 12v lighter that's in the trunk to the front of my car. Amazon has a generic 2.1amp for 3 bucks.
http://www.amazon.com/Premium-Heavy...121&sr=8-1&keywords=htc+amaze+car+charger+amp
But on ebay, I found the original HTC car charger for 15 bucks which is a 1amp.
http://www.ebay.com/itm/HTC-Amaze-4...918506?pt=PDA_Accessories&hash=item27c867022a
What do you guys recommend? My logic says go for the 2.1amp, the phone will draw as much as it needs from it.
The 1amp.
Anything higher you'll damage the phone or the battery.
A wall plug power supply or a usb supply is 5.0v/1amp.
The 2.1 amp is probably 1 amp per port. Although it does not seem to specify.

That means a higher capacity battery (more current NOT MORE VOLTAGE) will damage the phone?!!!!
Totally wrong!
A higher current will not damage the phone. A higher voltage will do it!
Please do not mix the current with voltage!
Voltage is same 5 Volts (±5%) for these “USB like” applications (1A or 2.1A power supply our case )They use USB socket/connector but usually only pin 1 and 4 (+ and-)
Regular computer USB port can supply max 0.5-0.9 A depending on version.
For battery charging devices the current can go to 5A.
Higher voltage will trip a warning window telling you to disconnect and use official HTC equipment.
The phone monitors input voltage to protect the equipment.

and to add to that... unless you take the charger apart and short pins 2 and 3, it will only ever draw 500mA, as it assumes that it is hooked up to a regular powered USB port... I have bought multiple car charger usb adapters, and I have taken all of them apart and soldered the 2nd and 3rd pins together... otherwise charge time = forever, and sometimes it won't even charge if you have wifi or data/gps/bluetooth all going at once...
I recently got an Amaze and am generally happy with it. The biggest problem I have right now is finding the right car charger for it because the car charger I previously used (a 1A monoprice car charger) doesn't give it enough charge. I have been reading through the forums and some has been saying that if the charger is not working properly, it will recognize it as charging via USB rather than AC. In my case, the phone seems to be reading it as charging through AC, but there still doesn't seem to be enough current going through it. The phone will only charge if NOTHING is going on (i.e. screen's off, no GPS, etc.). I've been using CoPilot GPS and it draws the battery like crazy. Anyone has any idea as to which car charger would work properly with the Amaze such that I'll be able to charge (or at least maintain the charge) while using it as a GPS? Do I need to go up to a 2.1A charger?
I would look for a 4-5 star rated 2.1a car charger on Amazon.
Just read through the comments and feedback and you'll find one that's right for you.
I prefer the USB charger base itself and then using the OEM cable that came with the Amaze.
It seems to charge faster with that cable, at least to me anyway.
Remember though if it's rated 2.1a but has two USB slots that 2.1a will be cut in half if used to charge two different devices.
Hope this helps.
I couldve sworn we talked about this months ago. Let me see if I can find the thread.

you won't get the full 2.1a unless you usee a charge only cable or modify the charger as I stated above...
I ended up getting a 2.1A car charger and a USB charge only cable, and it's working perfectly. When I have the screen on full brightness and doing navigation with Co-Pilot GPS, my phone's no longer losing charge and is actually charging. The combo also works with my tablet as well.

This is damn helpful! So THAT is why when driving and using gps or whatnot I would always lose more battery even on charger.. So basically I can just solder the middle 2 pins together to trick it into thinking it is being powered like a home charger? No chance it will hurt anything I assume?

Weird Charging Method!!! Challenge accepted???

so i think i have the most weird droid razr out there. in order for me to charge my droid razr i have to take two wires wrap them around the battery terminals and connect the to a special made charger ( usb or wall charger with a hot and ground wire sticking out). the phone does not say it is charging when i do so but after connected for awhile the phone holds charge just like a regular charger. also when i try pluging a regular charger into the phone to charge it it says its charged a 100% but the phone will not keep charge and eventually cut off. if the phone dies it will only come on witht the special method. if using a regular charger the phone displays and battery with a question mark inside it. i figured that it has something to do with the two connecters on the board that touch the battery connector. not the battery terminals but the two prongs inbetween the terminals. i have not found a actual fix for this problem and the phone is such a good phone its worth doing this to get it to work. if anybody has any ideas on how to permanently fix this so i can go back to using the regular charger i would like to here it but until then the challenge is still unaccepted let me know what you think

[Q] Phone Not Charging - Draining While Plugged In

Hey, been on these forums for a while, I rarely ask for help (been pretty lucky with the phones), but I have a question.
My phone won't charge. Or rather, it requires a time consuming process of fiddling, unplugging, replugging, and sometimes minor surgery on the USB port with a toothbrush or a tool I've crafted out of a Q-tip. However, after a night of charging (or some interrupted equivalent that results in a charged battery) the battery quickly depletes while still plugged in.
This is most clearly illustrated when yesterday, at 8:45 I rolled over and checked my phone to see if it had been charged. Pleased to see that it had been charged up to 100% I fell back asleep. When I woke up again to go to school at 9:10, my phone was entirely dead. I couldn't even get it to turn on to the point where it showed the I9100 screen. After following the time consuming and frustrating process of fiddling with the USB port and Micro USB charger, I coaxed the phone to show the powered-down charging screen, where I left it to charge to full.
I have been experiencing this over the course of a few weeks and I have tried many chargers, but only one of them will work at all (Interestingly a Motorola cord). Upon inspection of the USB port, nothing seems out of the ordinary, though the 2 prongs on the outside of the USB port male receiver look slightly different than the inside 2, though they difference is symmetrical.
Does anybody have any idea of what could be plaguing my phone? USB or battery? This is my second SII, a replacement one after my original one was tragically lost in a hot tub . Any thoughts would be awesome.
Thanks
Braidonh
If you are using Siyah kernel have you altered the charging current through EsTweeks?
If so then it is possible that the battery / charging circuit has been damaged. Try resetting the values to default (I think its 700mV on AC and misc and 600mV on USB but dont quote me).
Failing that then some hardware trouble shooting (trying a new battery / external battery charger) will help you figure out what is going on.

My signature is quite outdated... Currently just running CM 10.1 with stock everything. Haven't tweaked anything in that capacity... but will try my other battery (if I can find it). Thanks!
I was having this same problem with my HTC vivid. I tried charging with may chargers, the phone claimed it was charging (orange light lit up) but the phones battery was dying while plugged in. Just like you said, the battery depleted rather quickly when plugged in. Since my phone refused to accept any form of charge I bought an external battery charger and some extra batteries.
However, last week I wondered if maybe there was some sort of dust, or small pieces of sand inside the Micro-USB port on my in my phone that were possibly "blocking" the charger from properly charging.
So I bought an air duster and blew air into the USB port of my phone. I guess there must have been something in there because that fixed my issue and now my phone charges!
Now I have 4 batteries for my phone and an external battery charger.
Try it on your phone, see if you have the same luck I had.

Maybe I'm missing something here because you seem to be experienced on this forum and understand about searching first.
Anyway, this sounds like the common USB problem that S2s have. It can be the jack or more typically, the flex cable. You replace the little board. Search for USB in this forum. I just changed mine with one I got on Ebay. Cheap and easy.

S3 not charging/home made charger.

Hi my s3 is no longer charging. The USB micro port is damaged.
I am not anywhere near my home at the moment and I really need the phone. So I made the most ghetto charger known to man. Which is basically just a stripped USB cable attached to some paperclips acting as springs to charge the battery when it is removed from the phone. This actually works surprisingly well and consistently charges to 88% in a bit over an hour.
However, what I'm really interested in (and I want to stress that this is only a temporary solution while I'm travelling) is what are the two gold pins in the middle, left on the back of the phone for?
I believe they are for attaching an extended battery to the back of the phone.
However I can't find any information on them, nor do I have a multimeter with me.
Can I just apply 4.5 volts to these two pins so I can charge my phone while using it?
Also which is positive and which is negative.
I just need a quick and dirty solution, thanks.
