larrylu Posted May 5, 2013 Report Share Posted May 5, 2013 I couldn't find my old thread for this wrap up report but some may remember my struggles to get my Nexus 7 tablet running Torque to stay charged. I finally got it. Seems the A/C charger that Nexus supplies shorts out the USB data pins to signal to the tablet that fast charge is available when plugged into the wall outlet. My two previous high output 2.1 amp car chargers did not short out those pins so all I got for charge was an anemic .5 amps which would not keep up with the use. I tried unlocking, rooting, and a custom kernel, to get the tablet to fast charge on the D/C device and that did not help. Finally I found a 3.1 amp USB charger ($9.95 Amazon) that offered fast charge for Android devices by shorting the data pins and I tried it. Magic! The tablet is maintaining 99% charge with short hauls. I also found USB cables available that offer the shorted data pins and that would most likely be another way to access the fast charge without changing the charger and probably that might work also....not sure but I'm sure glad I finally got the Nexus to work the way I envisioned. dalum 1 Quote Link to comment Share on other sites More sharing options...
