Yes but that last 10% drain before total discharge seems to have a disproportionate impact on Lithium based rechargeables, and if the low voltage cutoff is set too low or the user defeats it by repeated attempts to power up then the battery is truly toast.
My suggestions are pretty much unchanged
* Don't run the charge so low the phone shuts down, unless you need the last few electrons to save a life.
* Don't try to overcharge above 100% unless you like pyrotechnic displays. (The phone should self-regulate and prevent this automatically)
* If the phone is to be left powered down for long periods (weeks...months) try to put it to storage with around 50% charge in the battery. (In reality this is only likely to be of interest to people like seafarers and deployed military who are away from usable cellular signals for extended periods)
