I was driving today and my phone was in its holder. At the time, I was using it for GPS and Pandora, and it was plugged in using my car charger. At one point, the notification LED began to flash in what looked like a regular pattern (but since I was driving, I can't be 100% sure), alternating between green and amber. I've never seen this before, and I had no notifications. What does it mean?

  • Was it flashing at an irregular rate? Its status could have been alternating between Full Battery and Charging.

  • I'll edit the question, but it was flashing in what appeared to be a regular pattern. I was driving, so I couldn't stare at it for a long period of time to confirm. Nov 27, 2010 at 15:06

I believe it means the battery is overheating.

  • Is there some way to check/confirm this? Nov 27, 2010 at 19:24
  • I haven’t been able to find any official documentation on this but there are various reports that describe the same symptoms and causes. For example: forum.androidcentral.com/htc-hero/… and forum.androidcentral.com/htc-evo-4g/…

  • Although there's no official documentation, the discussion forums seem to back this up. Unfortunately, I have no desire to test this out myself...until someone can find concrete reasons why this might not be the reason, I'm going to accept this answer. Dec 7, 2010 at 15:32

I think is because it is advising that the Micro USB is connected to charge the battery, but the battery is not charging, temperature or other reason
