Query about battery performance

[Avradeep]

I am Avradeep Hazra, an user of Samsung Galaxy F41, which I bought in the month of December, 2020. That time, when I fully charged (i.e. 100%) my phone, it showed a battery life of 1day 12hours. But now, within 7 months of using, it is showing battery life of 1day 3 hours after a full charge. I can't understand why this degradation in battery performance happened. Can you please give me an explanation? 

 Hoping for your prompt response.

Charge upto 80% to prolong battery life leaving some part uncharged keeps it healthy
Every time we charge 100% some part of the Li ion battery deteriorates

Depends upon your usage

It's software intel-analysis based on your usage. Initially it showed u 1day 12hrs because u were not using the mobile that much.
That is just an indication how long ur phone will last based on previous used patterns. Every week ur phone generates a unique battery life hour based on the usage of that week.
For eg: if you use your phone daily for only 2 hrs for a week then it's shows 2.5 days of battery standy
It's just an idea made by phone based on usage patterns. And it changes once you change the pattern of usage.

Dont worry man it is just estimation based on ur use

[hedgehog]

If u continue upto 80% charging prolonged life and probably use based analysis will show average 1 and half day full battery coverage for months

Depends on usage, if you use less it will show more time and if more reverse process
