Welcome to the Forum, and we are delighted that you are here. This is a very basic question -- not that it isn't important, because it is -- but it is also one that has been asked and answered a thousand times, with a lot of discussion. To ask such a question without first using the search feature to find the answer will try the patience of what otherwise is a very helpful group.

@mchen123 , keeping the battery at either a very high or very low state of charge degrades battery life. You can charge to 100% without problems if you are going to depart soon after on a long trip where you need the full charge.
If you want the technical electro-chemical reason for this, which involves the buildup of molecular dendrites on the anodes and cathodes, do a search on this site for some great explanations.
When you set your max charge on the charging screen, note that 90% is labeled as the upper end of the Daily Charge range. You can go lower if don't drive very far every day. I only charge to 70% unless I'm leaving on a trip.
