Magazine springs don't loosen up. They lose a small percentage of tension initally but leaving them stored loaded doesn't make them looser after that.

What weakens mag springs is use.

As already mentioned several times get the Uplula. It sure makes it easier. I used my Uplula's to load my P365's magazines especially the 15rnd mags. I don't know if I could load them w/o the Uplula.

I keep one in my range bag, one in my handgun hard case and one in my gun room.

That's the best 30.00 or so you can spend.

Yeah, yeah, yeah.

Load up that magazine and let it sit a while and it will be considerably easier to load again.

I've had some mags that I let sit for long periods, and they became useless. I had a P2000SK in which all the mags that sat loaded lost their spring and after stripping one round, the rounds had insufficient compression from beneath to properly feed. When I approached an HK rep at the NRA convention that year, he stupidly said it was user error...for letting the magazine sit loaded.

Yes, it's compression and release that eventually wears the mag springs out, but loading them to capacity and letting them sit will make them a lot easier to load in the future. The P365 mags are notorious for being stiff when new. Every one of mine has born this out; yes, they're stiff, but load them up and let them sit, and they're a lot easier to load by hand, no problem with a loader like an uplula.
