[bentenison]

From past 2 days I've been seeing excessive battery drain isuue in my samsung s21fe device R5CT4285EYY. I mean one day at night battery was 73 percent and till morning only 18 percent was left without usage. I am having difficulty even to make a full day out of it. I need samsung to please fix it bcoz this issue developed on its own from past 2 days and i am having difficulty with having it as my primary device

Common battery drain at night will be 3 to 4%....if you are having this much drain means maybe your mobile data,location was on...use routine save battery at night for reduced battery drain...

Dear Samsung Member,

Greetings from Samsung Customer Support!

As per your concern, we would request you to kindly perform the following steps to resolve your issue. However, we are taking your valuable feedback regarding this.

Charge in one go instead of charging many times as it affects the life span of the battery and battery performance

Perform Battery Optimization
Battery optimization helps you to boost the battery performance of your device. To check battery optimization:
Settings > Select Device Maintenance/Device Care/Battery and device care > Optimize > Optimize all options like Battery, Storage, and Memory

Turn off Wi-Fi, GPS, Bluetooth, etc.
Turn off unused functions like Wi-Fi, GPS, Bluetooth, and location settings when not using them: On the home screen swipe down the notification panel > Turn off Wi-Fi, GPS, Bluetooth, and other connectivity features when not using them.

Check device network fluctuation
Kindly check whether the mobile network fluctuates frequently or if the network signal is low in your area. In both cases, the battery will drain considerably fast.
Recommendation: We recommend you avoid using it in areas with low network/fluctuation.

Reduce display brightness level
Kindly set the device display brightness in auto mode (If available).
Adjust screen timeout settings: Settings > Display > Screen timeout > Select minimum screen timeout.

Check and update the App: Kindly check which application or interface is using more battery from device care. And try to update the app or avoid using that app.

Close background running apps
Close all the background running apps when not using them,

Turn off auto sync of e-mails, app data, etc.
We request you turn off the auto sync option, it will stop the synchronization of the device with the server & reduce the battery drainage.
The steps to turn off auto sync are:
1. Swipe down on the home screen to open the notification panel.
2. Turn off the auto sync option.
