My battery charge indicator (the screen info saying % full), flashes on/off/on/off, etc. sometimes.

I've switched the battery to a spare to see if that helps but it didn't.

When it does happen, this seems to happen at all the different wall sockets where I am. It happens a lot in cafe's.... perhaps not surprising... but also in my office building which seems pretty solid for such business services.

The only place it doesn't happen is at home.

My original theory was that it was due to too many people using the same circuit and reducing the amps too much. However the more places I see this behavior in, the less I think it is likely.

Any idea how to address this?

  • Have you tried using a different cord/charger? – Bryan Denny Jul 3 '12 at 21:12
  • yes. Looks like that was it. The cable went into a mini plug usb socket. – Michael Durrant Jul 4 '12 at 4:13
  • Same issue, cheap cable. The phone isn't detected by OS. – user598527 Apr 13 '17 at 10:54

Have you tried using a different cord/charger?

It seems as if it isn't related to a specific location, so I would suspect that the cable has gone bad.

  • This did not really work for me, I even tried a USB cable connected to my mac. – Gaurav Agarwal Dec 31 '13 at 11:51

Maybe the voltage supplied is too low for your tab to boot up with a completely drained battery. My suggestion is to try using original tab chargers or try charging your tab with a car charger. Using a JBL tab charger might work.

Mine does this ONLY when i use it in the garage, and I have an overloaded power strip, too many things plugged-into one outlet. It's not getting full power perhaps?

This may be a symptom of NSA eavesdropping. Another sign of NSA eavesdropping on your calls is quick battery drain within 1-2 minutes. I Suspect being monitored as Im constantly questioned each time I come into the US. Mail being redirected and opened, then delivered, etc. Good luck
