Thank you for sharing your concern. Performance of battery depends on various factors; any third party application, software glitches may cause trouble. Kindly follow below mentioned steps to overcome the issue.
1) We recommend you to charge you handset with original wall charger that came with your handset sales pack.
2) Kindly clean the charging point of your charger and battery with a dry and soft cotton cloth to remove unwanted accumulation of dust/waste material.
3) You can also check the charging process while device is in switched off mode.
4) We also suggest you to charge your handset with alternate Samsung Approved charger to exclude the possibility that current charger is not the root cause of failure.
5) Check whether Bluetooth, WI-FI, GPS, Bluetooth, NFC / S Beam, Tethering and Portable Hotspot is turned off when not in use.
6) Check whether the brightness of the device is set to minimum.
7) Smart Features in Flagship phones like Motion UI, Smart Stay, Air Gestures, and Screen Mirroring / Smart view etc. will drain battery considerably.
😎 Check Power Saving Mode (If available)
9) Auto Sync of E-mails, App data etc. will drain battery.
10) Multiple Applications running in back ground will drain battery power.
11) Network Fluctuation also drains battery.
12) Minimizing the back-light time would save battery.
13) Follow the standard charging procedure (i.e. charge a fully discharge battery in Switch-off mode up to 150 minutes.)
14) Periodic Software Update through KIES, FOTA or Smart Tool is intended to improve the battery life as well.
• (Setting>>About Device>>Software Update>>Update) update using 4G/3G/ WI-FI connectivity.
15) Check by Go to setting>Application Manager>Running>Stop downloaded application when not in use.
