Is the old charger rumor true?

    USB stands for universal serial buss. A standard developed to insure consistatcy across devices and connections. I use my OG charger and my old EnV2 charger on my Bionic with no issues. I use a multitude of MonoPrice USBs to connect data and charge. I use a RadioShak car charger. All that being said, I have seen enough posts on the Bionic to know that this doesn't work for everyone for some reason. The Razr may be the same YMMV scenario

    I just got a Razr and have been going crazy with these issues, thinking at least any decent USB cable would work. However, I found that if I don't use the Moto charger and Moto USB cable I have trouble getting the phone to charge all the way. Also, I could not make the phone and computer recognize each other to sync USB (so I can download Rhapsody music to my sd card) until I saw a thread here and went out to my car and grabbed the USB cable the Razr came with and, voila, instant sync!

    I decided to not take any chances after spending so much on the phone. I went to the Verizon store to buy a wall charger. :blink:

    What you say is correct, to a point. USB standard is for certain specs, but doesn't cover things such as RF inference, voltage and current purity, etc. I did some testing last night with several different charger adapters I have, and found that the non-Motorola/Verizon charger adapters all caused the screen to go bonkers. Swap out them for the approved chargers, the screen responds normally. I plan to take a video of the proof and post it on youtube for everyone to see.

    Again, I am not saying this it's the same for all phones, not am I saying it's the same for all Motorola phones, but on the Droid 1 and 2, I can conclusively say it's so. It had been so across many replacements of both models. When I get my RAZR tomorrow, I'll see if it is so with that one as we'll.

    Personally I would switch chargers on the Droid Razr. I had a hard time with battery life on my razr when I first got it but then I went out to california on a trip and lost the charger. So when I got back, I switched to my old blackberry storm's charger and it seems to have improved battery life on my Razr. It is a 5w 700 mah charger, I don't know if that is higher or lower than the Razrs included charger but it has improved my battery life.

    I hate to bust your conclusion derived from a couple of D1's, but both MY D1 and Bionic charge/transfer data with no issues on any cable or any charger I described in my post #21 above. I don't doubt that yours has issues. Why some phones only work on only the factory charger/cable and some work on anything is above my paygrade, but both sides of the issue have multiple people posting in multiple threads in this forum.

    Oh I must have read wrong...lol It works flawlessly for charging my D2 and Razr both chargers. I thought he was saying those worked..Not sure if the manufacturer likes the idea but I've had success...

    I am studying to be an instrument technician. I've had to take AC/DC circuits. Higher current (ma) can cause damage to a circuit and will affect the charging speeds. Generally lower current will not damage a circuit, but may cause it to work improperly. When using a higher current it can affect the battery and possibly fry your circuit. It is best to use the correct voltages/currents to ensure proper function. On another note I got a charger for my D2 that came when I needed a refurbished phone. This charger only puts out 550ma. But, this could be due to the needs of the circuitry considering they don't use just the parts for that specific phone. Not sure about the refurbished phone but I am pretty positive on the needs of a circuit.

    I use my moms LG charger every night cuz it has a longer cord, hope this isn't hurting anything. Also my phone runs exactly the same plugged in or not. I do notice that the house charger seems to charge the phone a lot faster than my car charger does.

    From what I know and what I've read some people experience the touch screen acting up. That could be due to lower current or voltage spikes or possibly interference of some sort. I know the touchscreen on mine doesn't work correctly when using a blackberry charger. I read that when charging, the phone uses the power from the charger not the battery so that could be the issue with the low current. But, if it is just charging low current shouldn't do any damage just charge slower. I know for a fact higher current can cause damage. Almost all chargers have the same voltage output. Frequency, I am not too sure on. I think I need to brush up on my circuitry. It's been a few semesters...

    In my best judgment to all, I would say ONLY use the charger that was made for the particular device... That said, I do use my D2 charger on the razr. The USB that is to give me the use of the dual USB wall charger that comes with the razr ...Awesome charger...hope this may help someone. I would not advise using after market parts unless your in a bind...Peace!

    Voltage is important, current just needs to be high enough. The phone only pulls what it needs. You can use a 2A charger, so long as it's 5V. Many problems with using old chargers are caused by not enough current, not the other way around.

    For the $$ we spend on these phones, you should at least use a manufacturer suggested charger on it. They are generally inexpensive. The gas station specials should only be used if your stuck without a oem charger

    I was referring to current.

    Huh? Amperage is current. You said you know for a fact higher current can cause damage. Not true. You can use any same or higher amp-rated charger provided it's 5V.

    Hmmm. I was pretty positive otherwise.

    No it doesnt really matter and in some cases it can be good i tested the voltage from my old trac phone and on my new charger and my old charger actually gave me more voltage so i use that now
