Please tell us some basic information before asking for help:

  1. Model Name: ZS661KS-6A006IN
  2. Firmware Version: 17.0823.2008.70
  3. Rooted or not: No
  4. Frequency of Occurrence: Always
  5. APP Name & APP Version (If your issue relates to the app): System UI

In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.


After updating to the latest patch system UI is consuming too much battery. Is this usual? Even on standby the battery drain has increased significantly. Pre-update the standby drain during my 10hrs sleep was around 5%-6% but now post-update it has increased to 10%-12%.


  • It's not correct data . As long as you are getting good sot don't worry .

    I also observed battery drain stats weird after updated to 70 FOTA. Then I charged to 100% and drained to 10%. Did this twice and now battery calibration seems to be working normal.

  • Hi,

    For Battery App usage battery time can be sometimes inaccurate, the main stats which matters is Screen on time. If that gives you a good no. then I think there is nothing to be worried about. 

    You can do a battery stats reset and try a couple of cycle - Charge to around 95% and drain till 10% this way the stats should Auto reset and may give accurate readings.
