[OnePlus 8 Pro  Guides, News, & Discussion] spiral5:
Hello everyone, I put a small tutorial to maximize the battery life of our Oneplus 8 Pro. As I describe, I have my unit configured.

If you want you can go reporting in the thread what results your terminals now show you with this configuration. I haven't done any bloatware, just uninstall Facebook and Instagram. Greetings.

1.- DEACTIVATE AUTOMATIC UPDATES.

In this way we will avoid that the mobile is constantly looking for updates and therefore consuming battery.

1.1- We go to the Play Store and in Settings / General / Automatically update applications, we mark "do not update applications automatically".

1.2- Once this is done, we go to the Oxygen OS updates. We follow the path Settings / System / System Updates, we give the little wheel that is at the top right and deactivate “Automatic download in Wifi”.

2.- DEACTIVATE THE WIFI ASSISTANT.

This option allows the mobile to automatically change the network, without us having to be aware of it, but it uses the battery unnecessarily. We are going to configure it to do it manually.

We follow the route Adjustment / Wifi and Mobile Networks / Wifi / Wifi Preferences / Inside we go and deactivate “Select the best Wifi network intelligently”.

3.-DEACTIVATE THE PRINTING SERVICES.

We have these services to connect to printers active all the time and the phone will be constantly looking for printers so that we can connect.

We go to Settings / Bluetooth and device connection / Printing / Default printing services, when pressing it it opens, once inside we deactivate it, we will see that on the screen below, we have a red bar with a text that says "searching for printers" This way we prevent it from being in constant search.

4.- DEACTIVATE EXPERIENCE IMPROVEMENT PROGRAMS.

We follow the route Settings / System / Experience improvement programs and deactivate the first three options:

“Oneplus Notifications”, “User Experience Program” and “System Stability Program”.

5.- BATTERY OPTIMIZATION.

We follow the route Adjustment / Battery / Battery optimization. Click on the three dots on the top right and Advanced Optimization will appear. Once inside we will activate the three options that we find, "Activate adaptive battery", "Optimization of standby at rest" and "Optimize energy consumption of applications".

6.- OPTIMIZATION OF THE GOOGLE ACCOUNT.

We go into Settings, select Accounts and inside we go to the Google account and open it, once inside we choose "Synchronization", we deactivate the following options:

Google Fit data / People data / Drive / Google Play Movies / Save Play Games in the cloud / Tasks in Calendar.

If you use any of these options, do not deactivate it or if you do not use any of the others, deactivate it.

In addition to the above settings I also have the following:

Display, FHD + resolution, dark mode, manual brightness at 85-90%, touch sounds, screen lock sounds, capture sounds, keyboard sounds, all off, vibration off.

In Developer Options:

"Registry Buffer Size", I have it set to 1Mb.

Window Animation Level / Transitions Animation Level / Transitions Duration Level. All three are by default at 1x, I lowered all three to 0.5x.
