Im going for an Xperia Z3, but battery

[Ultimate-Biohazard]

Ok, Im about to take another decision to get a phone, a cheaper one due ...Mexico and poor economy, I want to buy an Xperia Z3, but, i saw many times the Z has the battery drain problem (Like my Z1 that drops to zero suddendly)

and i i saw this phone may have it


I want to ask

DOES this phone drain drops its battery that bad?
My z1 has likely 60/40 % and drops to zero instantly, I dont want to have that problem too
I could go for Xperia X, but is a bit more expensive,and Xperia Z3 has the 120fps option..


Thanks for reading and hope you can help me with this decision
