Why they are so many rumors about smartphone battery?

 

There are so many rumors about smartphone batteries, for example, some say that charging from 0% to 100% will improve battery life but others disagree. Fast charge is good for battery health, others say no it will damage the battery.

Reasons:

• Long-Term consequences is hard to measure
• Usage types
• Technology evolution
• Different battery types
• Hundreds of manufactures

Long-term effects:

Obviously it is hard to measure a 2 to 3 year period of battery life, measuring each cycle, discharge rate, charging rate and etc...  Requires time and patience and it is often expensive.

Different usage types:

People don't use phones equally, A gamer drains the battery in 3 hours while an average user uses the same device for days and the list goes on...
It is not possible to measure each type of usage and their effect on battery health, at least with current technology.

Technology evoloution:

Imagine a company spent time and effort to know the good & bad about a batteries health. While the measuring is done. A new type of battery has already hit the market, so the measurement would be useless and they should redo it for the new battery type.

Battery types :

We have different types of battery. Li-Po, Li-ion and etc....
Each have different properties but this one is easy to tackle because 90% of manufactures use Li-Po and Li-ion.

Tons of manufactures:

There are tons of battery manufactures for smartphones, each company in smartphone, Laptop and tablet industry has it's own battery lab, SAMSUNG, Xiaomi, Dell, Apple, HP, HUAWEI, Sony etc...

What we know for now:

Research centers have some information in hand now, including:

• Do not discharge your phone to the max, charge it when you get the charge warning.
• Charge to 100% every month to ensure your unused parts of the battery get a refresh. Not recommended to charge to 100% in every single time.
• Use latest fast charge platform, each new version add optimizations for security and health of the battery. for example Fast charge 4+ added more heat control which is a great factor.
• Use certified charger, don't use a 5$ charger for a 500$ phone.
• Remove bulky casing when charging, to make the battery nice and cool.
