My answer to Is it bad to charge your phone over night?

Answer by Allen He:

As we know, our smartphone batteries are bad as they barely last a day. At the earlier days when we buy it, it’s the fault of smartphone manufacturers. But what about several days later? It’s to some extent your own fault for charging it wrong this whole time. For example, charging phone overnight.

Firstly, let’s have a look at the following saying: charging phone overnight, or more specifically, charging phone when it’s already fully charged, will keep it in a high-stress, high-tension state, which will surely do wear down the battery with lasting damage at the same time.
So, is it true? Is charging phone overnight bad?
Well, you’d better ignore that. We couldn’t be more wrong.
And the truth is that Charging phone overnight will not harm your battery in the slightest. Any device with a Lithium Polymer battery must incorporate a charging circuit that will cut off charging power when the battery reaches 100%.
Besides, the smartphone battery is as smart as the phone itself. Apple, Samsung and all the top tech companies, almost of whose products use lithium-based batteries.

That aside, however, Lithium-ion batteries don’t need to be charged all the way to 100%. While your phone runs troughtout the night, it loses battery life. And this will cause the charging mechanism to kick in over and over again as amounts of battery drain occurs during standby when checking emails, receiving text messages, and updating various apps while you sleep.

Let’s take an example. If you head to bed at 11 p.m. with a battery percentage in the single digits, your phone will be fully charged by 2 a.m. If you wake up at 6 a.m., that’s 4 hours that your phone stays plugged in with a full battery.

So what is the optimal way to charge your phone? That is to keep them charged between 50 and 80 percent.

Additionally, we have to mention Charge Cycles, that is, your battery goes from empty or near-empty to full. Every phone battery has a limited number of charge cycles before the end of its life. An iPhone has about 500 charging cycles. When charged up from 90%, only 10% of a complete charge cycle used. Whereas, when charged up from zero, then a complete charge cycle done. Or you’ll actually shorten your battery life if you do so.

Surely, here is another good idea for charging, or portable charging. And that is to take a power bank in hand, in pocket.
