Doesnt work at all and drain the battery

The Smart Alarm doesnt work on highest sensitivity it always alarms at 8:15 if I set the alarm from 7:45-8:15. On the same place Sleep Time and Sleep Cycle works perfect. And Sleep Bot drains battery much faster in spite of it should activate motion tracker only 30 minutes before the time set and Sleep Cycle monitor motions for the whole night. The only advantage is that I can add how long I slept manually in Sleep Bot.
