Draining battery 10 time than normal after android 15 in every mode even in standby mode and when playing games, it gives only one hour of battery backup. I reported through feedback options, contacted customer care services but still no update.Congratulations to IQOO Company! This is the legend IQOO 12! The Gaming phone! Monster inside (draining battery 🤣🤣🤣)! Useless upgrade, useless updates! 

To IQOO agents, team and company: why are you releasing updates before 1 or 2 months than other companies without fixing glitches/bugs/ and without checking! Is your brand for test trials so that other companies can launch next upgrade without glitches, when you fix glitches in next upgrade. Is this the reason for releasing upgrade months before for other brands. And what about your customers? From last 1 and half month battery backup is like 10 years old phone. What about battery health? Take my example, i am charging my device atleast five times per day since your upgrade 15. My battery health is also decreasing due to charging again and again in same day. Now my battery health is only 89%! Who is responsible for this now. Whenever you fix this problem, may be in 1 month or 2 months, but what kind of benefit will i get, may be my battery health may decrease more till then! Will you pay for next battery? It was nearly about my 1 years salary to purchase this device in 58k. You don't have any right to waste my money giving these kind of useless updates. Hope you understand!
