ESP32 Low-Power Optimization Sprint (Battery & Sleep)
$0.00
Extend ESP32 battery life by profiling real power draw, fixing wake leaks, and implementing deep sleep and duty cycling correctly.
Description
This sprint is for ESP32-based IoT products that work functionally but die far sooner than expected.
If your device:
-
Drains battery even in “sleep”
-
Wakes up too often or unpredictably
-
Uses Wi-Fi / BLE inefficiently
-
Needs months (not days) of standby life
This sprint turns power behavior into a controlled system, not guesswork.
What You Get
✔ Power consumption diagnosis
Measured analysis of idle, active, transmit, and sleep currents.
✔ Deep sleep & wake strategy fixes
Firmware changes to correctly use deep / light sleep, RTC memory, and wake sources.
✔ Peripheral power gating recommendations
Identification of peripherals and GPIOs that leak power and how to shut them down safely.
✔ Before / after power profile
Clear comparison showing improvements achieved and a battery-life estimate model.
✔ Low-power checklist (ESP32-specific)
Reusable checklist your team can apply to future firmware updates and manufacturing tests.
Scope
-
ESP32 firmware (Arduino / ESP-IDF)
-
Deep sleep & light sleep configuration
-
Wake sources (timer, GPIO, ULP, RTC)
-
Wi-Fi / BLE duty cycling strategy
-
Sensor sampling schedules and batching
-
Firmware-level fixes only
Hardware redesign or PCB respin is outside scope but can be advised separately.
-
Battery IoT products draining too fast
-
Devices that “never truly sleep”
-
Field-deployed nodes needing long standby life
-
Products approaching production or certification
