Deepsleep only works sometimes

[LMolenkamp]

I'm trying to program a ESP32 to run with batteries, and collect accelerometer data with MPU-6050, but my deepsleep only works on short periods of time, i was trying to make him function during 5 minutes, and deepsleep for 55 minutes.

This is my code, i'm kinda new, so any tips are helpful.

Thanks.

Try
esp_sleep_enable_timer_wakeup(TIME_TO_SLEEP * 1000000ULL);

It didn't work, i tried the new code, but after 10 minutes collecting, he still doesn't sleep
