This is bad advice if you want your battery to last longer until you need to buy a new one.
Full discharge cycles might give you a slightly longer charge for the next cycle but they reduce the overall lifetime of the battery as much as 3-4 drain/charge cycles between 20% and 80%. A battery that continually runs 0% to 100% drain/charge cycles will only live 300-400 cycles, versus a 20% to 80% battery that may live 1200 cycles.
You might think the tradeoff in battery lifetime versus charge duration is worth it but as the battery loses lifetime, its maximum charge will be reduced so you'll quickly have shorter charge durations.

- pytrin 13y agoYou are correct. I also mention the tradeoff between discharging very low to battery life, with a link to a nice article on the topic.
- magic_haze 13y agoI've seen this advice floating around the internet before, and while I agree with the lower limit, who the hell charges their phone to just 80%? I just plug the phone in at night and let it charge to 100% while I sleep. Is there even an option on smartphones to do anything different?

- akhilcacharya 13y agoThis is done just once in order to finish calibration. It shouldn't be done more than a few times if possible.
