You need to work on optimization. iPhone 16 pro max almost completely discharges in battery saving mode after 7 hours of continuous operation. Also, it has long process of searching for records when using the Util function (the process can stretch up to 7 seconds of waiting after the entered request) when I need move records. Frequent errors when synchronizing offline phone data to online.This process is interrupted and when re-synchronizing it continues again until an error occurs after a dozen records. It has also too long optimization of large-sized photos when loading. You need to add clearing the application cache. Why is this still not there. When exiting offline mode and entering online, an error occurs, and entry is possible only the second time. Also, when synchronizing offline data in download mode, the music that was playing via Bluetooth stops. And so every time synchronization occurs. What does the application have to do with music playback? All these problems are observed on the iPhone XR, iPhone 13 Pro Max, iPhone 16 pro max.
