Li-ion Battery Care

With the currently widespread use of Li-ion batteries (starting from mobile phones, laptops, and so on), it's interesting when people discuss about how to care for it in order to get the most out of it. Here are 2 of the most interesting articles I've found so far on the subject:

• Getting Great Battery Life
• Apple - Batteries - Notebooks

Recently, I also found a thread started by DarkDvr back in 2010 on the XDA-Developers forum specifically for Android-powered devices. The 1^st post there summarizes his findings regarding Li-ion battery care taken from sources like Wikipedia and BatteryUniversity. Here is my compilation of some interesting points, not just from the 1^st post, but through the entire thread (page 7 as of this writing):

1. A complete, full FIRST charge is recommended for 12 hours.
2. The slower the charge - the longer (long-term) battery will serve you. Trickle-charge (USB) is best.
3. Frequent partial charges about 40 to 90 or so percent are probably the best.
4. Calibrating should be done every 30 or so days/partial-charges: drain it fully (keep turning the phone on after it's "dead" until it doesn't turn on anymore) and then charge it to 100%.
5. Don't worry about charging your phone to 100% everytime. Charging to max voltage every time reduces battery life.

However, at the end of the day,

The thing with Li-ion batteries is that you don't really have to worry too much about them, it'll die regardless. Just keep it cool whenever possible, and don't let it die to 0% (aside from the calibration cycle).
