Battery Life

The number of shots or movie footage that can be recorded with fully-charged batteries varies with the condition of the battery, temperature, the interval between shots, and the length of time menus are displayed. Sample figures for EN-EL20 (1020 mAh) batteries are given below.

•Still images: Approximately 220 shots

•Movies: Approximately 50 minutes of HD footage at 1080/60i Measured according to CIPA standards at 23 ±3 °C (73.4 ±5.4 °F) with the camera at default settings, a fully-charged battery, a 1 NIKKOR VR 10–30mmf/3.5–5.6 lens, and a 16 GB Toshiba SD-E016GUXUHS-I SDHC card. Value for still images obtained under the following test conditions: photographs taken at intervals of 30 s with the built-in flash fired with every other shot and the camera turned off and then on after every ten shots. Value for movies obtained under the following test con- ditions: a series of 20 minute movies with a file size of up to 4 GB were recorded; recording was only interrupted when tem- perature warning was displayed.
