Hey! So about the battery life for the Canon EOS R100, our info mostly touched on image stabilization, but let's focus on the battery.
The EOS R100 uses a rechargeable LP-E17 battery, which is a pretty standard one for Canon cameras. When you're just taking photos, the battery is good for about 320 shots per charge, based on the manufacturer's specs.
But keep in mind, if you're using the LCD screen a lot, taking long photo sessions, or using the flash often, you might run out of juice faster.
For video recording, it's a bit different. You can expect about 1 hour and 30 minutes of continuous shooting, depending on how you've got it set up. Using features like image stabilization can drain the battery quicker as well.
If you're planning on shooting for a while, it might be a good idea to bring an extra battery or a portable charger. It'll help make sure you don't miss anything important because of a dead battery.
While it's not as long-lasting as some of the higher-end models out there, the EOS R100 is compact and lightweight, which many find convenient.
Most folks say the battery life is decent for casual use—but having a backup plan with extra power is always smart for longer shoots.
Hope this helps!
