iphone 14 battery drain
I got new iphone 14 around 6 days ago and at that time it was giving good battery backup but I had to reset it because of data remaining to transfer but after reset and setting it up again it gave half battery backup than before and also when I restart the phone it drops 4-5% battery I also went to service centre and they did restore and update saying it might be due to ios bug and also diagnosed it later on their diagnosis dock and no issue was shown in the analytics data but still facing the same issue battery draining heavily can someone please let me know normal sot on iphone 14 and also how do I fix this issue?
iPhone 14, iOS 17
