**Samsung S21 FE Battery Drain Issue: Need Help!**

[Asad7715]

Hey everyone,

I hope you're all doing well. I wanted to reach out to the community because I've been facing a frustrating issue with my Samsung S21 FE. My phone's battery seems to be draining excessively overnight, even when I'm not running any apps in the background and have turned off all unnecessary settings. 

Usually, I lose around 20% to 25% of my battery life overnight, which is quite unusual. I've always been careful with my phone's settings, and I'm not a heavy user, so this rapid battery drain has left me scratching my head.

Here's what I've tried so far:

- Checked for any rogue apps running in the background, but there don't seem to be any.

- Turned off features like Wi-Fi, Bluetooth, and location services.

- Lowered screen brightness and set the phone to power-saving mode.

- Cleared the cache partition.

Despite these efforts, the issue persists, and I'm left with a drained battery every morning. 

I'm hoping some of you might have experienced a similar problem or have some insights into what could be causing this. I'd really appreciate any advice or suggestions you can offer to help me solve this battery drain mystery.

Thanks in advance for your help! 🙏

You can say it's because of Exynos.

Exynos is a type of chipset used in s21 fe and other samsung phones

Don't think so I run exynos as well a weaker chipset on a midrange phone but there's no battery drain at all!

May be network issues. As 5g being implemented recently, in some areas especially in indoors, the network often keeps switching from 5g to 4g and vice-versa. In this case when 5g implementation gets improved your device might be back to normal as before .

See the settings I mentioned there. But I think it may be the problem with the battery. Do you fast charge your phone? Overcharge? Is protect battery on? Turn off AOD?
