Best time to charge your phone?

jackroo · Apr 5, 2013

I know there are a lot of threads about batteries, battery life, etc but I was just wondering what is really the best time to plug in your charger? Some say around 20%, some say 10% etc. I heard it's bad to just let the battery fully die. Anyone have some more accurate info on this? Thank you!

It honestly doesnt matter with lithium ion batterys mate. They dont have a "memory" like the old nickel cadmium ones :thumbup:

I charge it every night, wherever the battery happens to be. If its getting low before that, I swap it out for a full one and put in on the wall charger

The way ive read it explained is that the battery has a life based on how many full cycles it has so say if you run the battery down only to 90% then charge it back to 100%, that only counts as 10% (a tenth) of a full cycle.. charging it from 50% every day is same as charging it from 0% every 2 days and so on so u cant really go wrong :thumbup:

The way I see it, use it however you please. If the battery goes bad, you can pick up some good ones off amazon for ~$10

Good point, funkylogik. That makes sense so thank you

Yep, just do what is convenient for you. I charge mine at night like rxpert every night without fail and rarely have to charge during the day.

I just go by convenience: charge every nite whilsts sleeping. But I do know that the experts at Battery University say that the battery will last longer if charged at about 70%. But, as usual, I ignore the experts

With the battery technology that's out there currently, there's no rule of thumb on when to charge your phone.

I usually charge mine overnight and keep it in the charging cradle when I'm at work.

So keeping your phone on charge after it reaches 100% does not reduce the life or performance of your battery?

Never noticeably affected any of the batteries in the phones I've owned, always charge mine nightly at various levels of remaining battery %.

The phone cuts current when it gets to 100%

Any real damage would take years to develop, and would likely take longer than the life of the battery to develop

A lot of factors influence LiIon longevity. Two important factors are number of cycles and time above 4.0v state of charge with around 4.2v being 100% charge state. 4.0v is probably around 80% remaining capacity. Some studies have shown storing LiIon batteries at 4.1v for 1 year can result in a 30% reduction in capacity of the cell. There is truth in minimizing the time your cell is fully charged to increase longevity. However as mentioned earlier batteries are relatively inexpensive and easily replaceable (unlike on the Apple devices).
