Version update

[daiguru]

Hi guys! I have 6s 128g version 10.1.1.
What will happen if i update it to latest version of ios? What will happen to the battery consumption? the speed and performance of my phone? I heard that if you update or upgrade to the latest version the speed of the phone will go slower. Need some advice. TIA

iOS updates contain important security patches as well as enhanced and new features. That reason in itself is a very important consideration when deciding to update.
