ios 16 battery draining and over heating
Since updating to maybe ios 16.5 i’ve noticed my battery needed to be recharged more often but with ios 16.6 a few days ago i have to constantly recharge my phone, it lasts about 12 hours and is constantly loosing power even when phone is idle. What can I do to remedy this please, my battery is 88% capacity, it’s reduced by 7% in 7 months. Thank you
