SSD upgrade for 2017 MacBook air

[lemonade09]

I'm interested in getting a higher storage name ssd for my MacBook Air. I only care about battery life and not peformance. I'm interested in the aura pro x2 and off the counter ssds combined with a Sintech adapter
Any suggestions much appreciated

There is no nvme drive that provides the same battery life as the Apple SSD.

There have been posts from people using the same nvme drive in different configurations and some experience a reduction in battery life by 20% while others experience as little as 10%.
