Cansado vs. farto vs. cheio
In Portuguese, expressing that you are fed up differs slightly depending on whether you are simply weary, completely out of patience, or speaking informally. While farto, cansado, and cheio can often be used interchangeably to mean fed up, cansado implies fatigue, farto implies reaching a limit, and cheio implies casual annoyance.
Cansado
A1Literally meaning tired or exhausted, this word suggests weariness resulting from a repetitive situation. It is the mildest of the three and is used commonly in both Brazil and Portugal to express that you resultantly have no energy left for a specific annoyance.
Estou cansado de pedir para você arrumar o quarto.
(I am tired of asking you to clean the room.)
O gerente está cansado de resolver os mesmos problemas.
(The manager is tired of solving the same problems.)
Ela disse que estava cansada daquela música.
(She said she was tired of that song.)
Estamos cansados de esperar por uma resposta.
(We are tired of waiting for an answer.)
Farto
B1Derived from the concept of being satiated or full of food, farto means you have had enough and cannot take any more. In Portugal, this is the standard, everyday word for being fed up. In Brazil, farto sounds slightly more formal, dramatic, or literary compared to the other options.
Estou farto de ouvir as tuas mentiras.
(I am fed up with hearing your lies.)
O cliente estava farto do mau serviço.
(The customer was fed up with the bad service.)

(We are already fed up with this endless rain.)
Ela ficou farta e decidiu ir embora.
(She got fed up and decided to leave.)
Cheio
A1Literally meaning full, this is used figuratively to mean you are up to here with something. It is very colloquial and expresses a high level of annoyance or impatience. This is extremely common in spoken Brazilian Portuguese, whereas in Portugal it is used but farto is often preferred.
Estou cheio desse trânsito todo dia.
(I am sick of this traffic every day.)
Meu pai está cheio das reclamações do vizinho.
(My dad is fed up with the neighbor's complaints.)

(The girl was sick of that boring conversation.)
Estou cheio de ter que repetir isso.
(I am fed up with having to repeat this.)
Summary
Use cansado when the situation has made you weary or exhausted. Use farto to express you have reached your limit (standard in Portugal, formal in Brazil). Use cheio for informal, emotional expressions of impatience (very common in Brazil).
