Battery life dropped after EMUI 9 update

[sKyb0y]

Hello guys
Just received the EMUI 9 update on my P20 Pro. The installation worked perfectly however I've noticed that after a few days of usage that the battery life dropped.

Is something that I'm missing or it because of Android Pie update? Or this is the Huawei way to make users upgrade?

Wait a couple of days... It's going to learn how you use the battery and improve

Wait a couple days, your phone will pick up your usage and improve on battery life

I did a factory reset and I'm waiting to see any changes.

Also Unlock Magazine was not working, photos weren't changing. After reset now magazine Unlock is working

Excuse my ignorance . How do you clear cache on this phone? And what exactly does it do? Will I lose any data/settings/etc.. ?

Thanks

Wipe Cache Partition on the Huawei P20
First turn off the Huawei P20 completely
Then turn the Huawei P20 on again while holding down the following key combination:
Power Button Volume louder Button Hold down the buttons until the Huawei logo disappears from the display and the screen turns black.
You can now release the buttons. This will now display the boot menu after a moment.

Please mark the entry "Wipe Cache Partition" with the volume keys of the Huawei P20.
Important!! Please do not accidentally go to "Wipe Cache Factory Reset" <-- This will erase all data on the internal memory.
The wipe cache partition, on the other hand, will not delete any private data from you.
If you have marked the correct entry, confirm this with the Power key.
The process is now performed on your smartphone, which usually takes only 1-2 seconds.
The boot menu reappears. Select "Reboot system now" and confirm with the power button.
You have just successfully performed a wipe cache partition on your Huawei P20.
Your system should now run faster again, the battery consumption should be reduced and the performance should be noticeably better.
