Editing MessagePad (section)

===Power options===
The original Apple MessagePad and MessagePad 100 used four [[AAA battery|AAA batteries]]. They were eventually replaced by AA batteries with the release of the Apple MessagePad 110.

The use of 4 [[AA battery|AA]] [[NiCd]] (MessagePad 110, 120 and 130) and 4x AA [[NiMH]] cells (MP2x00 series, [[eMate 300]]) give a runtime of up to 30 hours (MP2100 with two 20&nbsp;MB [[Linear Flash]] memory [[PC Card]]s, no backlight usage) and up to 24 hours with backlight on. While adding more weight to the handheld Newton devices than AAA batteries or custom battery packs, the choice of an easily replaceable/rechargeable cell format gives the user a still unsurpassed runtime and flexibility of power supply. This, together with the [[flash memory]] used as internal storage starting with the Apple MessagePad 120 (if all cells lost their power, no data was lost due to the non-volatility of this storage), gave birth to the slogan "Newton never dies, it only gets new batteries".
