Ever since I flashed GrapheneOS onto my phone ( Google Pixel 9 PRO XL ) my battery life has severely improved even on heavy use, I thought you had to root your device to under clock the device for better battery life.
But nope because all the background bull shit is taken away EVEN with the google services sandboxed and running the battery life is greatly improved my phone is almost 3 years old and charges to about 80% and I can get 2+ days of heavy use now instead of about 6 hours or so.
Such a great improvement, thank you so much Graphene Devs, you made a great OS for us keep up the great work!
Also if anyone is reading this, to get banking apps to work you just need to bypass securities and or go on auditor and DNS and add them to allow or trusted list.
Have a great day everyone!
