For a low battery state of charge and colder temperatures, power management changes are temporary. If a device battery has chemically aged far enough, power management changes may be more lasting. This is because all rechargeable batteries are consumables and have a limited lifespan, eventually needing to be serviced or recycled. If you are impacted by this and would like to improve your device performance, replacing your device battery can help.
