these have a problem with the battery connector not being on all the way because of a short cable you have to open the tablet up and either tape connector in place or extend cable I have fixed 2 of these tablets by doing this it would shut off at 20% or not charge fully see this link http://freaktab.com/forum/tablet-support-android/nextbook-tablets/16839-shaunmt-s-modified-rom-for-nextbook-nx785qc8g-support-thread?16263-ShaunMT-s-Modified-ROM-for-Nextbook-NX785QC8G-(Support-Thread)=
