iPhone 4S Battery Draining While Audio Playback
Hi, I have a black unlocked 64 GB iPhone 4S. It runs the iOS 5.1. No jailbreak, I bought the factory unlocked model. Lately my iPhone's battery seems to be draining too fast. I played music with Beats Studio, and after like 10 minutes the battery dropped 2%. It can standby up to 10 hours and 4 hours of usage from 100% to 30% of the battery. Should I replace the battery? When the battery is low the battery seems to drain faster. Before, I also used PING but it didn't drain as much as now. Please post what you think and thank you.
