We are continually working on improving battery life. One thing that may help in the meantime is using Dark theme, which was a top mobile request added to Teams mobile in February.

Microsoft Teams kills my battery life. I have been using it for maybe 2 weeks for daily meetings. My battery life on full charge went from 98% to 90%. One 30 minute meeting takes my phone from 90% to 63%!!! This is NOT OKAY. I am charging my phone to full TWICE a day because of it.
