Fast charging has become an important feature in modern times; nearly all new phones pack the convenience of faster charging, which helps users get their phones charged faster. However, at the deep-down level, many think that fast charging is, in turn, ruining the battery of that very phone.
In recent decades, and as this question appeared to treat it, two years of study were undertaken to get the results for fast charging and the effect on the life of phones.
Is Fast Charging Bad for the Battery?
Virtually all smartphone batteries draw their power from lithium-ion batteries made specifically for fast charging. The Achilles' heel of fast charging, though, which reduces battery life, is that it builds heat during fast charging.
From an outcome of the research, high temperatures appear to be inflicted upon the battery while charging fast: Elevation in temperature accelerates the chemical reactions inside the battery cells and therefore damages the cells at an extremely quick rate. However, this may not mean the same for everyone.
Battery Performance in the Second Year
According to the study, fast charging had no considerable effect in the first year; by the second year, however, battery performance had declined, with the charge taking more time to complete. This was due to diminishing capacity from excess temperatures and pressures resulting from fast charging.
So, what happens is, the more you fast charge, the greater the reduction in battery cycles for the long run. After a while, you will start getting a charge drop-off from your phone's battery, and eventually, the charge will not reach a full charge.
Pros and Cons of Fast Charging
Fast charging means bypassing charging processes while the application saves further uploads to the battery in a limited period. However, these limitations also exert damage on fast charging processes. Relatively, with time, it degrades battery performance.
Battery Management Guidelines
A compromise to the longevity of one's phone may necessitate light use of fast charging. Performing timely charging will maintain battery vigor, while extended charging periods should be assiduously avoided because of susceptibility to overheating.
Charging should also start preferably at levels between 20% and 30%. Experience dictates that running down the charge most of the time below 0% or 10% should be discouraged in order to prolong the battery life.
Conclusion
The damage caused by fast charging occurs to the battery of the phone in the long run. Most users would hardly feel this damage; it would also differ according to the type of battery use and environmental conditions. With perspective, to maintain the health of the battery of the phone for a longer period, one should control the use of fast charging in conjunction with battery consumption.
