Hermione's capacity for and relentless pursuit of knowledge makes her one of the most powerful characters in the Harry Potter universe. Of course, she doesn't look it, but there are plenty of times when she demonstrates this throughout both the books and the movies.
Albus Percival Wulfric Brian Dumbledore was the only wizard Voldemort ever feared and the only one who could have defeated him in a duel. Albus Dumbledore is the most powerful wizard in the Harry Potter.
Harry achieves a higher mark in their Defense Against The Dark Arts O.W.L., but Hermione grades higher in every other lesson. This includes Charms, Potions, and Transfiguration, all complicated methods of magic capable of overwhelming Harry's defensive skills.
Hermione could beat Dumbledore any day if she wanted to. She's one of the most brilliant minds of her generation; like any good Gryffindor, she's brave, loyal, and strong. She mastered advanced spells at a young age, could make any potion perfectly, and her quick thinking saved her, Ron, and Harry more than once.
28 More Powerful: Hermione Granger
She was not only extremely talented, but she was also very smart, and in the end, her wits would have given her the upper hand against Voldemort.
Harry's other best friend, the bookish and kind Hermione Granger can't be beaten in the classroom. Harry recognizes her as his year's best student and even said so at some point. But while Hermione can ace any test, she can't quite keep up with Harry on the battlefield.

Perhaps Hermione would have had some trouble against Voldemort in her early years, but as an adult witch, she could certainly give him a run for his money if not outright demolish the Dark Lord. Her power combined with her breadth of knowledge is tough to beat.
The power you are born with is the power you keep. Hermione, however, is one of the few characters who achieves great skill mostly through hard work. She edges out many other strong characters in Harry Potter due to her prodigious work ethic, friendship, and ability to get even more powerful overtime.
In each installment of the Harry Potter series, Hermione Granger is the smartest of the trio. She has the best academic memory, highest grades, and always expanding her knowledge. However, it is Hermione's logic and by-the-book mentality that allows Harry to surpass her.

Ginny is the youngest in the Weasley family but one would argue that she is the most powerful. The movies show a little bit of it but in the books, she can throw some pretty powerful spells right alongside Hermione, who happens to be one of her closest friends.

Even though Hermione is the brightest witch of her age, Bellatrix far outclasses her in terms of magic, may it be duelling skills or knowledge of the Dark Arts. If Hermione wanted to duel Bellatrix, then she should at least practice the Unforgiveables, most importantly Avada Kedavra.

Weak: Quirinus Quirrell
Although he was intelligent and bookish, Quirinus Quirrell was the weakest of the Hogwarts professors—mostly due to his extremely timid nature. He taught the Muggle Studies course for several years before going in search of the vanquished Voldemort.

Hermione was good at defensive spells and charms, but she was once caught and hurt by Bellatrix, which should be enough to suggest she couldn't defeat the evil witch in a duel.
If they had ended up together, it wouldn't be that much different from the world we saw in Cursed Child. It'd just be a lot more Hermione and Harry talking about their kids instead of the two just talking to each other about the wizarding world at large and how they could help.
She wasnt madam Pomfrey. Meaning, while she had a general knowledge of various spells, she did not have the expertise in healing specific spells to be able to heal a death wound on a house elf. Their physiology is very different from wizards.
