Xiaomi Has Included Headphone jack In Mi 9 SE Smartphone which is a good thing in my opinion. All the brand are not taking interest in the headphone jack and removing it. Coming to 3.5mm and earphones, the 3.5mm port provides a punchy and clear sound.

Battery life:

My Mi 9 SE Thinq lasted a Full Working day with heavy usage and at the end of the day, I had 15% of charge left in the phone which is good for a 3500 mAH Battery. We got 4.5 to 5 Hours of Sot( Screen on time) on using Mobile data which is good. you will get above 5.5hr Battery life if you use Continuously on WiFi. The ideal drain of Mi 9 SE is very low. the 18W Quick charging 4+ makes a difference and charges the phone in 110 min which is a bit good.
