No.

Neither does plugging it in and leaving it plugged in overnight.

The circuitry is smart and designed to prevent issues.
 
When will these old battery myths finally die?

You can charge/discharge your battery as much as you want, as often as you want, any time you want. Please spread the word because rechargeable batteries have not worked the way that a lot of people think they do for a long time now

 
No... why does everyone obsess about thinking they are going to do something to damage their battery? Do you really think Apple would sell millions of something that could be damaged by simply unplugging it at the wrong time?
 
There is a difference between "damage" and causing "increased wear" ultimately affecting battery life. For example if you charge from 20% to 50% and then stop it and use 20% and then charge all the way up to 100%.....will that have more wear than charging from 0-100% in one go?

No is the simple answer
 
The worst thing you can do for your phone battery is discharge it to 0%. The second worst thing is to let it sit for long periods of time at 100% (although this is much less worse than a full discharge). Using it between say 20-80% the battery will last nearly forever. This is how Toyota manages the batteries in the Prius that are discharged dozens or hundreds of times every day and last for 10 years or more.

I do this all the time, I plug it into my car when I get into the car, and I unplug it when I leave the car. When I am at home, I plug it into the wall, and unplug it when I need to use the phone. The only time the iPhone stays off the charger for the whole day, is if I am on the bus/train/in somebody elses' car for the day. I have been using iPhones like this since 2007, and never with any of my iPhones I have had a problem with it's battery life.

And even those worst type of scenarios won't have much of a noticeable effect, unless perhaps they are occurring very regularly and/or for really prolonged periods of time on practically a daily basis.

My understanding is that the phone handles all that automatically. You can not truly drain your battery, as 0% is still leaving a buffer of a charge. Same with 100%.

So just use your phone, OP. Don't worry about the details.

Basically yes that's true. Apple does a better job than most at leaving an adequate buffer at 0% - but it's still the worst state for your battery - even if indicated 0% is really 5% or whatever.

Why not? It didn't stop them selling millions of devices that could be held the wrong way :D haha
