Battery drain fast and have to keep charging

just let it die and then charge it to full. do this for several days and see the improvement

How long have you been using the phone? Is the adaptive battery on? It takes a few days to learn your usage when it's new. My battery backup improve after using it for a month or so.

For a month

If the adaptive battery is turned on then I would say give it a few more weeks. Initially I used to get around 4 hours of Screen On Time on heavy usage with 120 Hz refresh rate and AOD turned off. After 2 months I'm getting around 5 hours SOT with the same usage. If after a few weeks the issue still persists then get your unit tested at the nearest service center.

Thank you

5hours of SOT is ok or normal?

[Phoenix10]

5 hours of SOT is pretty decent for a phone with flagship specifications. If you charge it fully in the morning it should last you the whole day.

And since this is an Exynos processor, I wouldn't expect a lot more battery life from them cause Exynos processors heat up more and it decreases the battery life.
