Discussion Overview

The discussion revolves around whether a phone needs to be recognized by a computer to charge via USB. Participants explore the conditions under which charging occurs, particularly focusing on different phone models and charging mechanisms.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant questions if the computer must recognize the phone for it to charge, noting their phone remains unresponsive after an hour of being connected.
  • Another participant suggests that recognition may depend on the specific phone model.
  • A warning is raised regarding the safety of charging phones with Li-Poly batteries, emphasizing the risks associated with improper charging methods.
  • Some participants assert that charging can occur without recognition, but the phone must support USB charging, as not all phones do despite having a USB data link.
  • It is mentioned that charging circuits may be located in the charger rather than the phone itself, which could affect charging capability.
  • A participant shares an example of a specific phone model (Razor) that requires software installation on the computer for USB charging to function properly.

Areas of Agreement / Disagreement

Participants express differing views on whether computer recognition is necessary for charging, indicating that multiple competing perspectives remain unresolved.

Contextual Notes

There are limitations regarding the assumptions about phone models and charging mechanisms, as well as the potential risks associated with using non-standard charging methods.

Ok, so my phone died :( and my outlet charger is broken so I charge it thru the USB. Does my computer have to actually recognize my phone in order for it to start charging it?

I've had it hooked for an hour now ... but it still hasn't turned on even for a second.

If your phone has a Li-Poly battery do NOT plug it into any old place. The battery can explode and burn your house down. Not kidding, Li-Po batterys are not a joke.
 
yes this will work
 
Grr ... I think it does need to recognize it :( it's still dead.
 
It doesn't have to recognise it - but it does have to be able to charge through USB!
Not all phones can even though they have a USB data link.
Sometimes the charging / battery control circuits are in the charger rather than the phone. Another problem is that the USB->charger plug adaptors just put 5V into the phone with no control - I have ruined phones with these before.
