Battery drain after One Ui

[varunfdo]

Once the One Ui was launched last week, my note 9 is facing massive battery drains and doesnt even last half a day as opposed to a full days charge previously. Is anyone else facing the same issue?

Thank you for being a part of Samsung community. We apologize for the battery issue facing in the device.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.
16) After doing the above procedure, kindly restart your device and check the performance.
17) Check the issue in the safe mode.
If issue still persists, KIndly provide logs/video within 15 minutes of issue occurrence by registering this feedback via Samsung member application i.e. Samsung member BETA app> BETA feedback>Sendfeedback>Error report>Collect log files>attach.

wow great

Thank you admin for the detailed explanation on what settings to check. I feel I have already done most of what you have recommended and still face this. prior to the update, I had battery power for a whole day. After the update it hardly lasts till the evening. is there any setting turned on by default in One Ui that I could change?

I too have same problem with my 3 days old note9. I charge the phone in the afternoon and 80% drains by midnight when most of the time the phone is idle.

mine was two weeks old when One Ui came.. I feel you..

I'm also facing above issue

[karthikeyans]

admin is just fooling us. the above said procedures is standard procedure followed. but current problem is due the bug in one ui which Samsung guys knowingly are not accepting the truth

so basically I had some service updated and the phone was back to normal - meaning by battery started lasting for more than a day. then again it's back to draining to half day thanks to some other service.

so this may not be a One Ui issue but some Google service manager or something.
