A7 lite battery health

[Anand_Avn]

I've been using this tablet since its launch, which means it's been around 2.5 years old. I've adopted the habit of limiting charging to 85%, and from a full charge down to 15%, I'm getting approximately 4.5 hours of usage. I'm confident that it will last up to 5 hours before it becomes completely empty. Even at 85% charge,the tablet is able to serve me for 4.5 to 5 hours consistently.

Additionally, I routinely utilize its full potential bykeeping data, Wi-Fi, location, and Bluetooth turned on at all times. Despite this, the battery performance u can see.

What r the ur phone nd tablet status let me know in the comments which make me to compare.

Dear Samsung Member,

Greetings from Samsung Customer Support!

Thankyou for sharing this, we suggest you kindly perform the following steps to optimize your device battery and to resolve the battery drain isssue.

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.
