A Dell Precision 5690 is a workstation with a high-power processor and an NVIDIA RTX graphics card, so a battery that empties fast under real work is expected, and the question is whether it empties fast at idle. Dell's battery guide points to the battery's health and settings. Open Dell Power Manager, which shows the battery's health and lets you choose a thermal profile and charge mode:
The checks in more detail
the Standard, Primarily AC and Custom modes control charging thresholds, and keeping a desk laptop at a threshold lengthens the battery's life while a laptop you carry should use Standard. The discrete GPU draws power when an app uses it, so check in Task Manager's GPU column and in the NVIDIA control panel which apps use it, and set the browser to the integrated graphics. The display's brightness and refresh rate matter, and a high-resolution panel uses more power.
Run a battery report with powercfg /batteryreport to compare the design and full charge capacity, and the diagnostics from F12 test the battery. A battery under two years old whose capacity is far below design is a warranty matter. Dell's software can also show which apps woke the laptop during sleep: run powercfg /requests in an administrator prompt to list anything keeping the laptop awake, and powercfg /sleepstudy to produce a report of drain during sleep;
a laptop that loses ten percent overnight has an app or a device preventing deep sleep. Keep in mind that the Precision's large display and RTX card make it among the heaviest laptops on battery, so for long days away from power use Dell's Cool profile, dim the display, close GPU-using apps and consider an external battery pack that supports USB-C Power Delivery at the laptop's wattage.

Model-specific
What is true of this model and not of its siblings
- Workstation power
- A high-power chip drains quickly under load.
- Charge modes
- They trade capacity for battery life.
- Overnight drain
- A sleeping laptop should lose little.
- Sleep study
- It shows which app woke the system.
Stop boundary
When this stops being a self-service repair
- !If capacity is far below design under warranty, contact Dell
- !If diagnostics fail the battery, ask for a replacement
- !A swollen battery means stop
