Solution 35699: TI-Nspire™ CX Family Handheld Battery Performance in a TI-Npire™ Navigator™ Classroom.

Why am I experiencing a quick battery drain in TI-Nspire CX Navigator classroom?

Problem:  User experiences a quick battery drain in 5Ghz Navigator class room if data collection  is also performed using EasyLink with certain probes/sensors. Fully charged battery lasts only for 3 to 4 hrs.

What causes this behavior?     
Some Vernier probes and sensors used with Easy Link require lots of power to operate. This combined with higher current requirements for 5GHz operation  leads to quicker battery drain (around 4 hours).

Products Affected: TI-Nspire™ CX.

OS' Affected: TI-Nspire handheld OS.

Action:  Following are the list of  sensors/probes that requires higher power. User should expect a quick battery drain if used and prepared for a recharging of the battery after few hours of operation.
- CO2  Sensor
- pH meter
- Force sensor
