[HD2 Android Q&A, Help & Troubleshooting and Genera] RealPariah:
Um, this is quite interesting as you know Android itself never goes to the FULLY charged or FULY discharged state of the battery's limitations PHYSICALLY. To do so as you point out with any number of variances in ambient temperature a device may be stored or used in would invite WAY too many problems of dead batteries. Also, the reported maximum and minimum valtages both on paper and to the device are not the ACTUAL maximum or minimum of the PHYSICAL battery itself [this gives overhead or extra space for the battery's life both in usage and in storage] as even in regular usage a batteries cells die overtime as they are used no matter how you charge/discharge the battery.

I find it interesting MANY people seem to be under the impression the device you use actually uses the FULL PHYSICAL limitations of the battery they have. This is just not the case [and why chips were included in batteries to report the battery voltage as a manufacturer wants and not the true physical capacity of the battery [again so they could include overhead to accommodate cell loss and random user usage that may not always be in within battery specification [speeding up that cell loss and reduction in life of the battery even faster].

Battery calibration [removing or wiping the battery stats file [however you choose to do so]] only affects how Android views the battery, and is why the battery percentage gets misreported over time [due to any number of reasons say an incorrect shutdown, wrong code in the OS causing a bug of some sort, etc.] and is the only thing addressed through battery calibration in Android [in restarting the affected files at the correct time to have the phone begin reporting statistics and thus the battery level correctly again. You are in no way really adjusting the physical battery [or the included manufacturers chip in anyway you are only correcting the Androids reporting of said information given to it.

Now of course you may slow down cell loss even more by staying even further within the lines [charging before auto shutdown, or only charging up to 98%], but again here this doesn't make full sense to me personally [I say some as you could say save a little bit of money over the 2 - 3 year standard life of a phone or device (usual expected usage life of a standard user of a device oh and yes you could buy a replacement battery as well in MOST devices [and this is why I dont understand newer devices like Nexus 7s who lock the battery in the device so you cant replace it, it's only really an attempt to get you to buy a whole new device when the life of the battery is spent, but the hardware is still totally fine and good to use]], but here again you run in to the issue of the Lithium Ion technology limitation of it's life span IN GENERAL [there are exceptions to this rule due to any number of factors including manufacturing quality, usage, if you freeze it etc] a Lithium Ion battery only has a TOTAL EXPECTED life of 3 - 5 years to include storage and/or usage. There are technologies beginning to come out that are going to change this [newer lithium polymer batteries [like what Duracell is doing now when they have that "Duralock" technology available in some of their batteries], but I am speaking to the standard Lithium Ion battery found in 99% of today's devices.
