Well, in my case, I was using a second hand Nexus One for years (almost 3 years if I remember it right) without problems with the battery. I think that if you respect the charging cycles, you make it last longer (I usually wait until 10% of battery left to charge it)

FYI, waiting until a Li-ion battery is nearly fully discharged before recharging will actually shorten its life by 3-4x compared to recharging when it hits 50%. See: http://batteryuniversity.com/learn/article/how_to_prolong_li...

Really? I've heard that by doing that what you are doing is reducing the time the battery will be charged (it's like instead of using 100% of your battery, it set its limit at 50%). I don't have the source where I saw this, sorry.

You may be thinking of the "memory effect" of old NiCad batteries, which indeed needed to be thoroughly discharged before recharging otherwise they'd lose capacity. However, LiIon is a different chemistry, and different rules apply. I don't know of any modern device that still uses NiCad, though I'm sure there's still some legacy niche where they're useful...

Do not follow his advice.

To lessen the strain on your smartphone battery, keep it between 15% and 90% of charge and don't let it become too hot.

Modern batteries are not like the old ones.
