Please be aware that the Philips PicoPix 4350 has 2 modes:

• Optimal mode: the battery lasts approximately 1,5 H
• Eco Mode: it lasts approximately 2 H

Important:
The battery charge depends also on the resources used, (Bluetooth and WiFi Direct functions). For example the battery autonomy can be as low as 50 minutes if WiFi Direct (4350 WIFI/4350 EXPLORER) is enabled. In such a case we suggest to use a 5 V/2A Power adapter like the Philips PPA6200, or a Power Bank.
