Zebra’s range of Android Mobile devices come equipped with Power Precision or Power Precision+ batteries. You can learn more about Power Precision / Power Precision+ from the product page but one advantage of these batteries for the app developer is access to a wealth of additional battery information not available on consumer Android handsets:
Last week James Swinton-Bland, Darryn Campbell & Rabeb Othmani (Bibi) had the privilege to once again represent Zebra at Droidcon London 2019.
Zebra’s series of developer conferences for 2019 has recently concluded with our AppForum event in Las Vegas.

October 24th – 25th sees the annual Droidcon London event taking place at the city’s Business Design Centre in Islington. Yet again, Zebra will be sponsoring the event giving us a booth and the opportunity to speak with and get feedback from event attendees.
