"How much battery is left?" Lin Li asked.
"Hmm? 72%. Why do you ask?" Qu Wanqiu turned her head and asked, looking puzzled after checking her phone.
"Charge it to 95% before handing it over to Xue Jian, it's good for the phone," Lin Li seriously suggested.
Chen Yu Ying and Ding Sihan looked up.
"Why? Is there some special reason?" Qu Wanqiu asked curiously.
"According to the latest issue of the 'East Asian Applied Physics Review', a phone battery is in a 'sub-stable gold state' at 95% — the lithium ions arrange themselves in a regular icosahedron lattice.
This structure can effectively reduce the entropy loss during electronic migration. Modern circuit boards use a bidirectional voltage balance design; the state of the electrodes is also most stable at 95% charge. Turning off and storing the phone at this charge level can extend its lifespan by at least twice compared to other charge levels.
Qu Wanqiu, you wouldn't want your phone to need a new cable soon, right?"
