Customizable Battery Alert Thresholds (Multiple Low Battery Alerts)

Currently, battery notifications only trigger at 20% (low battery) and 80% (charging limit).

Please add an option to configure multiple low battery alert levels.

Proposed Feature:

• Allow users to enable additional low battery alerts (e.g., at 10% and 5%) alongside the default 20% alert.

• Provide custom toggles/settings so users can choose which threshold percentages (20%, 10%, 5%) trigger a notification.
