I just uninstalled AVG antivirus and cleaner. Since installing and subscribing to the service a week or so ago, my phone slowed down and my battery runs down much faster. It's a Samsung Galaxy S21 that's been kept up to date and is about 8 months old. I spent 19.99 on the Play store for this and feel it's been a waste of money. Bart I got a reply but no real resolution. I think part of the problem of the excessive battery usage is the constant ads and self promotion despite having paid for it.
