Fast battery draining issue in new s21 ultra

[karan08]

Hi, 2 month back I purchased new Galaxy S21 ultra, and I have noticed the battery drains pretty fast. In the normal use its always empty before the day ends. I also did the all battery saving settings in phone but I am still facing the problem.I compared with other Samsung S22 ultra and S23 ultra. My New S21 ultra battery drained super fast as compared to S22 ultra and S23 Ultra. Also I have checked battery health but its showing good. Pls suggest.

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.

Battery life depends on how the battery is used. Note that different devices have different battery life. The expected battery life for your model can be found in the manual.

We would like to inform you about the standard charging procedure (charge in one go instead of charging many times as it affects the life span of the battery and battery performance).

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.

Dear sumsung support team,

Thanks for your suggestions, I already tried all the above-mentioned methods, but I didn't get any results. Also, I am an old samsung customer I know about battery life.

It's my new phone. It's hardly 2 months back I purchased. In full charge its showing 13 hours only.

Pls suggest..
