The devices are on fairly even ground in terms of radios. Both have dual-band Wi-Fi a/b/g/n and Bluetooth 4.0. Neither has NFC. Both devices build in sensors for GPS, gyro, accelerometer, compass and ambient light. Both offer an LTE option; Apple also provides iPad minis for GSM/EDGE and CDMA networks. The Galaxy Tab 3 also can control televisions, cable set-top boxes, audio/video and other electronic components thanks to an IR emitter.
Samsung includes a 4000 mAh battery but does not publish ratings or estimates of usage hours between charges. On its 4490 mAh battery, Apple claims nine hours while surfing the web with a cellular radio or 10 hours using Wi-Fi, listening to music or watching videos. Over the years, we've seen tremendous improvements in Samsung's battery-life algorithms, but Android is no Apple. And iOS is still worlds ahead in terms of battery life. iPad mini runs iOS 6.0; Galaxy Tab 3 7.0 runs Android 4.1.2 Jelly Bean.
