"Don’t wait until your phone gets close to a 0% battery charge until you recharge it, advises Cadex’s Bradshaw. Full discharges wear out the battery sooner than do partial discharges. Bradshaw recommends that you wait until your phone gets down to around a 35% or 40% charge and then plug it into a charger. That will help preserve the capacity of the battery. You should also keep your phone cool, as higher temperatures accelerate the loss of battery capacity. Pro tip: Take off your phone’s case before you charge it."
Kaya kung mapapansin nyo mas mataas yung chance na uminit yung phone kapag galing sa lower percentage, Pero sa ROG PHONE 2 ko, ginagawa ko hindi ko siya hinahayaang bumaba ng 20%, kaya makunat parin battery ko, And also, mapapansin nyo rin na yung ibang phone nag ii-stop magcharge due to high temperature(feature ng mga bagong phone). Lithium-ion operates safely within the designated operating voltages; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage. Prolonged charging above 4.30V on a Li-ion designed for 4.20V/cell will plate metallic lithium on the anode. The cathode material becomes an oxidizing agent, loses stability and produces carbon dioxide (CO2). The cell pressure rises and if the charge is allowed to continue, the current interrupt device (CID) responsible for cell safety disconnects at 1,000–1,380kPa (145–200psi). Should the pressure rise further, the safety membrane on some Li-ion bursts open at about 3,450kPa (500psi) and the cell might eventually vent with flame. And lastly my own advice kung gusto niyo humina consumption sa battery niyo, use dark themes(wallpaper/darkmode/nightmode), check and turn off unnecessary Start up applications, disable location, at wag masyado iexpose sa maiinit na lugar yung phone(lalo na kung nagge-games) yun lang po. this is my own opinyon and some research hehe
