Canon EOS 1100D Battery life

All figures are calculated based on CIPA (Camera & Imaging Products Association) testing standards (see the section titled "Standard Procedure for Measuring Digital Still Camera Battery Consumption" for more information), and assuming the following power supply condition:

1. One fully-charged Canon LP-E10.

Viewfinder Shooting – Approximate Number of Shots

1. Temperature 23°C / 73°F, Autoexposure only (no flash used): 800
2. Temperature 23°C / 73°F, Autoexposure 50%, Internal flash activated and used 50%: 700
3. Temperature 0°C / 32°F, Autoexposure only (no flash used): 750
4. Temperature 0°C / 32°F, Autoexposure 50%, Internal flash activated and used 50%: 650

Live View Shooting – Approximate Number of Shots
Two LP-E10 batteries, with an attached battery grip:

1. Temperature 23°C / 73°F, Autoexposure only (no flash used): 240
2. Temperature 23°C / 73°F, Autoexposure 50%, Internal flash activated and used 50%: 220
3. Temperature 0°C / 32°F, Autoexposure only (no flash used): 230
4. Temperature 0°C / 32°F, Autoexposure 50%, Internal flash activated and used 50%: 210

At 23°C / 73°F, the Live View mode can stay switched on for a duration of approximately 2 hours, or 1 hour 40 minutes at 0°C / 32°F.

Movie Shooting Time
With a fully-charged LP-E10 battery pack, Canon quotes the following approximate durations:

1. Temperature 23°C / 73°F: 1 hour 50 minutes
2. Temperature 0°C / 32°F: 1 hour 30 minutes

Other Battery Life Factors
In the T3 Manual, Canon advised that the battery life and number of shots decreases when:

1. The shutter button is pressed halfway for a prolonged period.
2. Autofocus is frequently activated without taking a picture.
3. The LCD Monitor is used a lot.
4. IS (Image Stabilization) on the lens is activated.

Some lenses draw more power from the camera's battery during operation due to their physical (heavy lens elements that need more power to move) and electronic (type and technology of the IS employed) properties.
