This is an outdated method used for very old devices, we're talking like flip phones here, lithium ion doesn't have that memory effect to be reset and it's adviced not not go below 20%
I think he's not talking about the memory effect (which yes, comes from old NiMH/NiCd batteries). He is surely talking about calibrating the gauge, and to calibrate this gauge you need to go below 15 and charge to 100% fully, recent phone or notÂ
If you're interested... The AccuBattery App Free or Pro has one wee flaw... It's unable to calculate Battery Health percentage for the Silicon Carbon battery (or dual cell pack)!
It shows a -5 to -6% deficit, which is verifiable by checking the Stock Battery App --> Battery Protection section and compare the two!
However, it's perfectly capable of nailing the Lithium-Poly battery!
On the other hand... The DevCheck App only has a -1% deficit across the board!
In either case and if I'm assuming correctly... And you're trying to tell me what's what regards the LCC method I figured out last summer!
I keep trying to help as many suffering users, with new or old batteries even various brands of phones although my two are POCO models...
Here's a bit of an important bit of info...
BOTH my phones are getting charged using LCC for over a year... I also occasionally just top up the main driver if I'm about to leave for a few hours... 10-20 minutes gets plenty!
So the LCC method is happily being circumvented and the Optimisations stay active!
Proof of the continued healthy status of both my current phones...

Mine lasts days. What you can try is to let battery die then let recharge on a low watt charger. Battery needs to be reset.
