Blokada 5 has been very nice to me, no root, and doesn’t use much battery (android tells me 4% after a full day). Only downside is that it counts as a VPN connection, so if you want to connect to another VPN you have to turn it off temporarily.
Otherwise definitely Firefox with ublock origin
Rethink DNS is an amazing app if you’re on android. Highly worth giving a shot! Even for the peeps on other solutions.
ublock origin on Firefox, VPN that blocks ads, plus most apps I install without network permission
When I’m outside my home network, I rely on Tracker Control (installed via F-Droid) for most traffic. And the usual uBlock Origin and such for my mobile Firefox browser.
If you have root, then AdAway: https://f-droid.org/en/packages/org.adaway/
I use it without root and it’s fine. Not perfect, but at least you can disable it if you have to without rebooting your phone
I’ve been using DNS 66 for a while with no complaints.
Can you use a VPN at the same time as DNS66?
Set your DNS to AdGuard servers. Downloads the Mull Browser from F-Droid with the uBlockOrigin addon, so you can browse the internet without ads. Download a Firewall: Netguard is recommended. Apps that don’t have internet can’t load ads.
If you have root: Firewall: AfWall+ Also, use the app “App Manager” from F-Droid to disable all app components that have “ad” in their name.
With this multi-layer approach you’ll deal with 99.99% of ads
