Do I Charge My Iphone When I First Get It. 3Charge it uninterrupted to 100. I would suggest giving it a refresher charge once taken out of the box.

Apple lithium-ion batteries work in charge. The iPhone 13 is available to buy. Theres no need to let it discharge 100 per cent before recharging.
Take the USB-C to Lightning cable you received with your new iPhone.
I bought yesterday my new iPhone X I charged it for about 2 hours before first use because I already have the old idea that the new batteries must full charge before first use and wait until full discharge before charging again is it a wrong idea. 1Charge it to 100 and keep charging it for at least 2 more hours. Dont forget to use the included wall. Only charge when it needs charging.
