Safari draining too much battery life

Thanks for posting in the Apple Support Communities Bcsbug,

First, determine if Safari us using power in the foreground or background.

To do this, tap Settings > Battery > Show Activity. The following page explains further: About the battery usage on your iPhone, iPad, and iPod touch

You can than use themes relevant guidance on the following page to make changes that will improve battery life: Maximizing Battery Life and Lifespan

We hope this helps!

Take care.

Tap the 2 squares at the bottom right in the Safari app and see how many tabs are open. Each open tab uses some power.
