The Indicator Upower now supports battery charging limit on MTK and other devices - don't forget to reinstall indicator if this feature didn't work in older releases.

Telegram preference wasn't really a choice by the community. It's mainly because Canonical amd Telegram had some kind of a partnership and there has been a native Telegram app for Ubuntu Touch right from the start. We even have push notifications working until now. Moving to Matrix is ideal but that would mean a need for a good native app and an intentional push and effort.
