What do your battery stats indicate after such a drain?

I would suggest installing GSam Battery Monitor. It tracks what processes are draining the battery, and should tell you what is sucking power. Example screenshots are below from my U12+...

That phone was released 5.5 years ago. I think it's safe to say the battery is toast. Even if you found a brand new replacement battery, chances are it's been sitting on a warehouse shelf for years and would likely be in just as rough shape. That, plus the abysmal specs by today's standards, and I suggest biting the bullet on replacing it with a newer phone. Trying to fix this issue would most likely be a never ending quest.

Alcatel Fierce One has 1800 mAh battery. and today's applications are used more battery. I don't think a new battery can more effective. if your battery is not working 8hr then you can replace.
