I have purchased my nothing phone 2(a) on June 5th 2024. I have purchased same nothing 45w charger with the phone. But I am facing heavy battery drain issues. I have done all updates but still same issue going on. Not even a standby for the phone. Daily morning I will charge but 90% and I will go for my work. I am not using phone on work time. Actually from 10am to 4pm there is no use for my phone. But while I take my device after 4pm the battery is showing 70%. I am very frustrated without any use 20% charge is lost. It was just 4 months after purchase. Please help me with this. I need an immediate attention on this issue.
