    This guy ^ is apparently an unknown disciple of mine! Good work! He's absolutely right. Draining a LIPO battery to the self-shutdown point (or worse...lower), is stressful to the internal chemistry of the battery and over time will reduce its live expectancy. Likewise, charging to the maximum amount will have a similar diminishing effect on the battery.

    This is evident in electric cars, where they have a "battery extender" charging setting which only charges the batteries to 85%, and shut down at 15%. This means the batteries only run in the middle 70% of the full cycle, and can result in from doubling to as much as 5 times the life (net 100% charge cycles), of the batteries. Considering a battery pack for a car can be $7,000 or more, it makes good sense to be gentle to them.

    Motorola and other manufacturers are trying to balance the wants and desires of the end users (long runtime, low weight and size), with the cost-effectiveness and engineering limitations of the current battery technologies. As a result, some manufacturers will install slightly smaller batteries (to cut costs), and then set the charge and discharge thresholds wider to allow for longer runtimes on one charge. This unfortunately means the batteries will start to show their age sooner.

    Other manufacturers (like Motorola with the RAZR MAXX), decided to go with a larger battery in a bigger footprint but with less bulk (thickness), and by having the larger "tank", they then set the charge and discharge thresholds narrower, so the runtime is comparable (and actually longer than competitors), but a the same time the battery lasts longer due to being less stressed at the top and bottom of the charge cycle.

    I have posted countless times about all of the information above and earlier in this thread, as well as in countless other threads. I've even gotten into a couple "heated" debates with a few who insisted, even with all the third-party information I was able to throw at them, that I was wrong...well, I'm still here, they're gone. I'll let the reputation speak for itself.
