Changing it makes it easier to identify in AirDrop transfers and in the iCloud device list.
Go to Ajustes > Geral > Sobre > Nome and type the desired text.
This simple change makes the device more personal.
Control background updates
By default, apps update content automatically, even when closed.
This consumes battery and mobile data unnecessarily.
In Ajustes > Geral > Atualização in Segundo Plano, choose Desligado, Apenas Wi-Fi or
Individually disable apps that don’t need constant updates.
This option preserves battery life during intense use.
Appearance and screen adjustments
iOS allows you to program automatic switching between light and dark mode.
Go to Ajustes > Tela and Brilho > Opções from Aparência to set custom times or use sunset to sunrise.
Features such as Always On Display, available on Pro and some recent basic models, can be disabled to save power.

Go to Ajustes > Face ID and Código > Acesso Permitido Quando Bloqueado and uncheck the option.

This function adds delay in unknown locations.

Set up emergency contacts in the Saúde app.
Go to Perfil > ID Médico > Editar and add numbers.
These contacts are accessible on the locked screen via SOS from Emergência.
Include medical information relevant to critical situations.
This simple setup can be vital in accidents.
Visuals and battery

Set to Tinted mode at Ajustes > Tela and Brilho for greater opacity and contrast.
Combine with background refresh limitations to optimize battery life.
Always On Display test disabled on supported models for longer duration.
These changes adapt the iPhone to each user’s profile.
