You are not the first - and are unlikely to be the last - to comment upon (and dislike) the revised style/presentation of the battery charge percentage to within the charging graphic icon. Arguably, this change introduced with iPadOS 27 significantly detracts from the legibility/readability of the battery status icon. This is not a configurable item; you cannot restore the prior presentation
Apple invites submission of constructive comments and feature requests via its Product Feedback portal.
If you would like to request that Apple reconsider this change and return the iPad battery status to its previous visual elements - or request that this becomes a configuration setting in a future release of iPadOS - this would be the most appropriate channel through which to make your request:
Feedback - iPad - Apple
You are unlikely to receive a personal reply, however, it is our understanding that all feedback is logged, analysed and forwarded to the appropriate team(s) for consideration. If a sufficient number of similar requests are submitted, it is quite possible that Apple will implement change - as has previously occurred with Apple's contentious Liquid Glass transparency.
Every request matters. If you would like to see change, it is in your own best interest to add your voice via the Feedback Portal.
The Apple Support Community is a user-to-user technical forum, that is not monitored by Apple Developers or Apple Support. Any comments or protests that you post here will not be seen or acted upon by anyone that can implement change.
