A junk phone maker anyway.
A friend got a g54 power because the online reviews praised the battery life, guess what, he needs to charge it twice a day, older phone with 1000mah less battery had better stamina. Screen is horrible, camera is junk. Earphone has massive sound distortion. He hates this brand now.
I've seen old spec laptopts used daily for 10+ hours for ages with no issues. They have protections or should have, depends on what brand you go for. Stay with known brands and you should be ok.
