Normally by getting the battery replaced. With the note 9 though software support has ended. Could treat your self to a new phone.

Make sure to back up all your data before. As you may have to factory reset if you choose to replace battery. Not sure if the note 9 has maintenance mode when repairing. Think that came along with newer software. Back up to the cloud or use smartswitch for PC. If you choose to upgrade device, just the case of transferring all data from old device to new.

Hey there and welcome to the Samsung UK and EU Community Customer to Customer Forum

Have you run the diagnostics tool on your device and if yes, is it telling you your battery is weak? Or do you say it is weak because the battery isn't lasting that long?

If it isn't weak in diagnostics, before you do anything, perform a Wipe Partition Cache on your device (especially if you've never done so before). This will clear old cached temporary files from your device and speed it up / reduce the battery usage to a degree.

You won't lose data doing a Wipe Partition Cache.

1. Turn off the device.
2. Connect To Computer USBC to USBC (you may also connect to another Samsung mobile via USBC). Press and hold the Volume Up key and then press and hold the Power key
3. When the Android logo displays, release both keys.
4. Wait until the Android system recovery menu options appear.
5. Press the Volume down key several times to highlight wipe cache partition.
6. Press Power key to select.
7. Press the Volume down key to highlight yes, them and press the Power key to select.
8. When the wipe cache partition is complete, Reboot system now is highlighted.
9. Press the Power key to restart the device.

If this doesn't work, there is also a way to optimise your battery.

@lminvti can you please add your link ref battery reset.

Again you won't lose data doing this but you do need to use the Samsung Phone App for the task, not the Google one.

Factory Data Reset would be your nuclear option and should be the last one used.

Also please be aware that the Note 9 will be out of support so you may also want to think about upgrading....
