1. Dim the tablet display. First up, and perhaps the simplest way to save battery life, is to dim the tablet display, much like you would on a desktop or laptop PC. Simply visit the battery usage page, opt out of the auto-brightness controls, and manually dim the brightness as you see fit.
Where is the Bottom Bracket on a bicycle? In a nutshell. Your bottom bracket is housed in the bottom bracket shell of your bike frame, it connects your chainset to the frame and allows the cranks to turn smoothly. When selecting a replacement bike bottom bracket you need to make sure that you get the correct model.
To summarize: When you specify your bottom bracket, you need to know: 1  The threading of your frame: BSC, Italian, French (or Swiss). 2  The taper of your cranks: JIS or ISO. 3  The length of your spindle in millimeters, depending on the type of crank you use.
