I believe Professor FoxKat once post a chart that shows this is normal.
You might be able to find a Razr charger on eBay.
I'm sure he'll chime in on this, as well as the rest of your post.
You know I am a stout believer in staying with the OEM equipment.
Can another charger work (loose interpretation of the word), well...yeah.
Can another charger cause unknown problems that could reduce the effective usable life of the phone and/or battery, well...yeah.
Can another charger's inferior power filtering cause distortion of the data being transmitted from the digitizer causing erratic response and "ghost touching/typing", well...yeah.
Can another charger cause distortion of the voltages and current readings of the battery while charging, resulting in either under or (worse), over-charging of the battery, well...yeah (and there are examples to prove it).
Can another charger cause catastrophic failure, well...yeah.
All of are here to learn. We're fortunate to have Professor FoxKat share his knowledge with us.
:blush:
What does the charger have to do with it? As long as it's with in 10% +_ of the voltage and amperage of supplied unit. I use my kindle, Bluetooth, and a dual output cube from Walgreen. Never had a problem with my X2 and Maxx.
Can a charger that falls within a safe range of the recommended voltage (+/- 5% - not 10%), and minimum current requirements (at least enough to support the phone if charging while powered on, and still have some left over to actually "charge" with), suffice for a timeframe in a pinch and have little if any long-term detrimental effects (whether detectible or not), well...yeah.
Case in point for the last comment. Yesterday, I broke my own golden rule. My phone died with 0% and powered down itself. It was completely unresponsive to power button presses, and I had left my back pack home due to an unrelated issue, so I didn't have my charger with me. So I thought...no problem, I have a spare Motorola power/data cable at my desk plugged in at all times to do data transfer. I'll just plug in the phone and the USB port on my computer will charge the phone.
I plugged in and the white light came on solid on the screen. Nothing else. I pressed the power button while plugged in, the white light flashed briefly - then nothing. So I am worried now. I decided to leave it connected to the computer and see what happens. In about 20 minutes, the screen popped up the familiar red circle with the Motorola logo and I was relieved. It booted into Charge only mode, the large battery icon appeared and it first showed simply a big ?...and after about 5 seconds, it showed 5%. Whew! I was really scared for a minute. So I let it do its thing and continued with my work. By the time I left to go home, about 2 hours later, I unplugged the phone, pressed the power button and waited for it to boot..........................................................NOTHING!
Plugged it back in, this time NO WHITE LIGHT! Nothing...absolutely nothing.
So I called my wife to tell her my phone was dead and that I wouldn't be able to speak to her on the phone until I got to my car and dropped the phone onto the Motorola Navigation dock which is connected to the Motorola Rapid Charger Adapter (which charges at 5.1V +/- 5%, 1Amp Max - 1000mAh). 10 minutes later when I arrived at my car, started it and popped the phone onto the dock, NOTHING. I disconnected and reconnected, and again, NOTHING, no light, no icons, no boot, nunya!
So I proceeded to drive home. After 10 minutes into the drive the phone suddenly booted into Charge only mode and started with the ?, followed by 5%. I decided to let it do its thing for the entire drive home, another 20 minutes. Along the way, I kept checking...10%, 15%, 20%, waiting to see 25% but it never got there. I took it off the dock at home, walked in and plugged it onto the Motorola Wall Adapter, it booted into Charge only mode again and showed 20%. I left it and did some chores, came back 15 minutes later, now it's at 40%!
Why did I go into all this? To once again say to those who believe deep discharging to 0% is no big deal, that I almost lost my phone to a deep discharge and to a USB charge that failed. SO... I'm on my soap box. I will not recommend, nor agree to bless anyone who uses any charger other than the one supplied by the manufacturer, at least until the "Charger Standard" is implemented in the USA. If it's already in play elsewhere I can't say and if so, then I say use at your own risk.
I also say that if you can avoid it, don't let your phone go to 0% under any circumstances. It may be the beginning of the end for you.
