Please do something to fix the battery draining issue for IQOO Z9. I'm so disappointed and regret buying it. The back backup is so worse!! You said that you have fixed this issue in the April trial update but the battery is draining high like before. 8 to 10% is gone in 1 hour of just normal usage. I have done all I can to reduce battery draining like restricting backround activities of many apps and stopping auto start of certain apps, enabling dark mode, etc. But the issue is not fixed. Another thing you should note is after the April trial update, sometimes 4G and 5G network is connecting but no internet is available. Before the update, both 4G and 5G used to work better. 

So, to conclude:



1. Fix the battery draining issue on IQOO Z9. Try to make the battery drain only 5 or 6% for 1 hour. It'll be good.



2. Make 4G and 5G connectivity of Mobile network better



3. Show music playback timeline when the phone is in fullscreen horizontally and also add an option to control the timeline of music playing



I expect all these features and fixes to be added in the next update soon!
