My first guess would simply be the battery is going bad and due for replacement. What are your charging habits like? I.e. How far do you drain it before plugging in? Do you charge overnight? How often do you charge it? And on a related note, is it shutting off before hitting 0%, such as at 10-20% left?

i start charging it when its like 30-20% but if im going out even if it on 60-68% i charge it and yes i charge it overnight and it shuts down normally on 0%

but before a few weeks when something was showing up on the notification bar that cause faster draining i managed to delete it (it was app DUrecorder for screen recording) on that same day and the next one i can remember that not only the battery fall but at 1% it took him 10 minutes(no joke) using to shut down

and because of that case i think that something is draining the battery and the phone cant show me what it is.....

Waiting until 20% is pushing it. Ideally it's best to plug in around 40%. I'm still leaning towards the battery being bad, given its age. You could try booting into recovery and clearing the system cache, as that sometimes helps improve battery life, but I wouldn't be surprised if that doesn't help.
