[Discussion] All You Need To Know About Charging Cycle!

Hi Mi Fans!
You may know that charging habit of your smartphones is very vital issue to keep your battery life for long time. Today we will discuss about battery cycle and battery life to use your beloved Xiaomi phone for long time.

About Battery Life and Charge Cycles
There are two camps on how to best protect the capacity of your cell phone battery: charge it when it’s dead, or charge it every night.

I’ve heard older NiCd battery technology should be deep cycled to avoid the old “memory effect”, but our phones, tablets and laptops all have newer lithium-based batteries. The conventional knowledge seems to be that completely discharging a lithium battery permanently degrades its lifespan. But I haven’t found a definitive source on how to best care for my battery.

As an Xiaomi user, I thought I’d check with Xiaomi first. For maximizing battery lifespan, their website suggests keeping your phone at the right temperature and adjusting your settings to use your battery less. They don’t offer any specific recommendation on deep vs. shallow charge cycling, but they do suggest going through at least one complete charge cycle (charging the battery to 100% and then completely running it down) per month. That seemed like an oddly specific recommendation with no data to back it up.

Measuring Battery Performance
When evaluating any kind of performance, engineers need a metric. The standard lifespan metric seems to be “number of charging cycles through which the battery can retain 80% of its original capacity”. For example, Xiaomi promises 300-400 charging cycles for your Xiaomi battery.

Temperature
I found an interesting part on the aging mechanisms of lithium ion batteries. Sure enough, there’s good science verifying that temperature play a  big role in battery lifespan. Most batteries are designed to operate at room temperature, and both hot and cold temperatures accelerator aging. They also note that battery capacity will fade over time regardless of your usage habits because the chemicals simply break down.

Shallow cycling
A researcher preconditioned a fraction of these batteries by shallow cycling those 900 times (draining just 7% of charge before recharging). Amazingly, he found the preconditioned (i.e., shallow-cycled) batteries were able to withstand about the same number of deep cycles as brand-new batteries. In other words, shallow cycling didn’t seem to degrade battery capacity at all!

Apple says its battery charge cycle is 500 before it goes below 80% charging capacity. Any one knows Xiaomi's claim, is it 300, 400 or 500?
