Is my cell phone battery broken, if so which Apple and Huawei cell phones have a good battery?

I have a Huawei P Smart 2019 since September 2019 I'm on my cell phone daily my screen time is 10-15 hours and if the battery is 100% charged then I use the cell phone for an hour it drops immediately by 10-20%. I have to charge my cell phone every 5 hours and that really annoys me. My cell phone is not old now or so, but is the battery broken? Please write me good Apple phones that have a better battery life. Huawei models are also happy.

For what and for how long do you use the cell phone? (3h music, xh., Etc pp)
did you close unused apps in the background?

Would say your charging cable is broken

This is a sign that the battery has lost a lot of capacity, the battery needs to be replaced, Huawei also gives a 24-month manufacturer's warranty on the batteries, but whether it works under normal use is another question when you use it
