Hello friend, just wanna share my experience to not making our ZFlip Battery drain fast. Since it is become common issue, with 3.300 mAh combining SD 888, the battery draining so fast. As a consider i am using my phone in general use but gaming. Texting in social media, chat via whatsapp, mailing and little bit of youtube. From 100% to 15% in just half day.
So this what i do to maintain the batteries:
1. Turn AOD to " tap to show"
2. Adjust the screen brightness to Auto
3. Turn off the Volte
4. Turn the screen refresh rate to 60 Hz rather than 120Hz
5. Turn on the adaptive battery, this will limit battery usage for certain apps
6. Turn on the eye comfort shield
7. Turn on the power saving mode, and last
If possible, turn on WiFi whenever available, it will lighten the mobile network not to always search the best network in range
Those, help me maintain the batteries to not draining fast, although it is not that significant.
Hopefully the next OS update will fix the batterie issue, and the heat issue too
