Lifeproof case and iPhone 5

So I have an iPhone 5 and a lifeproof case. I tested the case when I got it and it worked fine. I use it periodically in water but not completely submerged. I have to take the case off every night to charge it because my charge cord is too large to fit inside the case. I wanted to use it underwater this summer but I did not want to use it if water would get inside and ruin my phone. Since I take the case off so frequently, will that affect the seal of the case?

If it's a solid brand like otterbox or casemate you're fine.
