Phone's battery drains very fast

[aarion]

I use Samsung A30 which I purchased in July 2019. I still wonder why my phone's battery drains so fast. At 11:05 am, it was around 81%. Now (at 14:43), it is now just 47%. I have disabled battery usage of all apps in my setting but still it happens.

I have to charge my phone 2 times a day. I start charging at 26-27% and stop at 82-87%. Once my battery charge percent goes below 26-25%, it drastically reduces to 0.

Time to buy a new phone.

I will buy it later. Currently, I have many pending important things which I need to buy. We have to buy a car and a land first. The problem is that we lack enough budget.

I don't want to spend more than ₹15,000 for a phone. I want a phone which is not less than 6.4 inches and doesn't costs more than 15,000.
