The battery life on a single charge will typically last between four and seven days, depending on individual usage (e.g., insulin delivery, CGM, frequency of alerts and alarms). For instance, if you utilize both CGM and the t:connect mobile app, a fully charged battery is designed to last up to four days.
The best thing you can do for battery health is to charge your t:slim X2 insulin pump each day for 10-15 minutes or until it is fully charged.
B. Causes for Battery Depletion
Battery Health Tips
- Charge your pump each day for 10-15 minutes or until it is fully charged
- Avoid leaving the pump plugged in for long periods when 100% charged
- Avoid frequently letting the battery fully drain to 0%
Causes for Battery Depletion
Just like with a cell phone, the more often the display is turned on, the greater the impact on battery life. You can help minimize your screen being turned on for longer than necessary by:
- Clearing alerts, alarms and reminders as soon as they appear
- Setting your Screen Timeout setting to 30 seconds (default)
- Turning your pump screen off before putting it away by pressing the Screen On/Quick Bolus button. Personal items in the pocket or purse can press against the pump screen and keep it active.
Other Causes
- Your pump is trying to connect to an expired CGM sensor. Check that the transmitter ID number you have entered is correct.
- You recently stopped a sensor session and did not start a new one. Unless your transmitter has expired, your pump may be searching for your transmitter even if the sensor session has been stopped. Battery depletion will return to normal once a new connection is established, or after 24 hours, if a new sensor session is not started.
- You are not using the t:connect mobile app, but you have your pump's Mobile Connection setting turned on. To turn it off, tap OPTIONS, Device Settings, Bluetooth Settings, and toggle the Mobile Connection off.
- Increased insulin usage can result in faster than average battery depletion
- You interact with your pump screen for longer than one hour each day. Increased screen interaction can result in faster than average depletion.
