With Lithium batteries, they are pretty much "charge them as you like, relax and enjoy your phone"
Please allow me to disagree vigorously. See
Battery University - How to Prolong Lithium-based Batteries. Sure you can charge them whenever, but if you drain them almost all the way every day, the battery won't give you full performance for even a year, and will be dead in less than 2. (As opposed to some 10 year old lithiums I still use in my 10 year old phone.)
1. Slower and cooler is better.
The difference in life between a 1C charge and a 0.5C charge has a smaller influence on lifespan than the difference in lifespan between batteries. That said, almost no phone charges anywhere near 1C (or even 0.5C - 1C with a 3750mA battery would be a 3.75 Amp charge rate).
as long as you are within the temperature range of the battery chemistry, the cooler you keep the battery the better it is (within reason - don't put it in the fridge).
As long as you stay within the
charging temperature range (which is different than the
discharging temperature range), there's very little change in lifespan.
Wireless charging is slow and as long as the circuit isn't generating heat, it's a great way to go.
Wireless receivers generate heat. If they're inside the case, against the battery, the heat is transferred to the battery by conduction. It's not much, but in a hot car it can make enough of a difference to harm the battery.
2. When possible, avoid the extremes. Charge to 80% or less, recharge at 20% or more.
Again, vigorous disagreement, and the above link. Try to never let the charge drop below 40%. Charging at above 60% gives you a slightly shorter battery life. (The chart is easy 4th grade arithmetic.)
Lithium batteries do not have a "memory", though a full charge/discharge can be helpful when you first get the phone
Three times. To condition the battery. If it's been sitting on the shelf somewhere for a few months or more. (And, since it won't hurt, do it with every new battery, since you don't know how long it's been since it was manufactured or last charged.)
and once every few months so the recharging algorithm in your phone can adapt to reductions in capacity properly as the battery ages.
"Recharging algorithm"? It's fixed in hardware, it doesn't "adapt". Only do full charge/discharge cycles if the battery has been sitting for a few months. (And let the charge drop to about 40% before putting it away for storage.) The charge file in Android has nothing to do with charging the battery. ("Recalibration" is about as useful as wings on a truck.)
With all that being said, Lithium has come a long way and you can happily use a properly designed fast charger and charge it all the way to 100% and let it discharge to shutdown every single day, and you probably won't see more than a 10-15% capacity drop in the first year.
Not borne out by actual testing. But treat the battery right - the above link is a whole course on batteries by a company that tests thousands of them (they make battery analysis equipment) and you'll get 100% performance after the first year, and a 10-15% drop after a few years.
And with more and more phones having to go into the shop for battery replacement (and manufacturers charging $45 for a $10 battery, 10 cents worth of cable and a 20 cent connector), it's more important than ever to maximize the life of the battery. $100 for a battery replacement every 6 months doesn't sound like much, but I'm sure most people have better things to spend the money on.
