Samsung A7 2018 / Oppo F9 / Vivo V11 BATTERY DRAIN Test | Zeibiz By Zeibiz

OPPO F9 and VIVO V11 are Philippine version with 6GB RAM. Let's set the screen brightness to 75%. Let's increase the brightness to 85%.85% screen brightness remains on during this test. Screen brightness is still on 85%. Let’s lower the screen brightness back to 75%. I'll play PUBG with HD Screen Resolution and High Frame Rate settings.

Again, let's increase the screen brightness to 85%. Let's check the temperature! OPPO F9 is at 44C!!! Oppo F9 is using the Low Temperature TFT screen display. But the device usually produce high temperature when set to 75% or higher screen brightness. It's the heat that drains OPPO F9 battery faster. Meanwhile, Samsung A7 2018 and Vivo V11 uses AMOLED screen display.

AMOLED is more efficient and consume less power. This is why A7 manages to survive longer even with only 3300 mAh battery capacity.
