The upgrade itself uses a good deal of power, and it continues to use power over the following hours as all of your apps and systems update. This is perfectly normal and can lead to temporarily shortened battery life and higher temperatures. Our research shows that it can take up to a week or 10 days before battery life stabilizes after an OS upgrade. Please do not draw conclusions about your battery life soon after it upgrades.
