    Allows me to go through a full work day with moderate to high usage. Which is about 10 hours before the case goes dead

    Exactly what I expected from this product. You MUST make sure the connection between the phone and charger port are snug and secure or it will not work. Otherwise a bit overpriced but that is what you pay to have the apple logo on a product. Overall satisfied. Would recommend for heavy phone users.

    It’s not the best but this case does a good job with maintaining battery throughout the day. But if you’re like me I’d like to keep the phone alive for more than 2 days without a charge even with darker backgrounds and dark mode. That being said, it’s a step in the right direction, but I could use a little more efficiency in using it throughout 3-4 day.
