It's often said, Lithium battery has no memory and stop when full, and won't overcharge. We can charge or discharge our battery at any time at any %..

Some still says it's better to charge it when the battery drops to 20% or never fully charges it, that will extend the battery lifespan...

Is it just NOT true and I don't need to worry about 20% battery or fully charged?

Just charge the battery when it’s needed, the battery’s lifespan is based on many different variables. Besides it can be replaced for $50 by Apple so not a big deal..

There are optimal percentages to keep the battery in, but that isn't to say that being outside of them is necessarily bad or damaging. You might be able to get slightly better battery life overall by really sticking to the optimal ranges all or most of the time, but how noticeable that improvement would be is fairly questionable and can still have some variety across different devices. So, for all the hassles of doing it all it's usually not really worth it, so the usual best way of just using and changing it when as as you need to or want to is generally the better way to go.

Thank all. However, Apple store in my country is very far from me and will take hours and hours to drive or fly so replacing battery is not feasible. Does anyone know if I can ship the phone back to Apple and they ship back for me

Will they still replace for $50 after expiry of 1 year warranty and Applecare expires

You can check out Apple's information about the price. It says they'll still replace out of warranty units for 49$ as long as it's eligible.

If you find that expensive, there are 3rd party sellers who sell DIY battery replacement kits. I did mine successfully. Just look up Amazon for those kits.

I'd also like to add that batteries and mobile devices are generally items that are consumable. Eventually, you'll have to replace it regardless. So my advice is to just enjoy your device and charge it when you need to. Worrying too much about something that's going to be replaced eventually is just a waste of time and energy.
