The charge controllers which charge the battery are really smart. They are designed by really great companies such as ST Microelectronics. These charge controllers typically have many features. (I don't know if the ST ones I linked have all of them. I just pulled those parts out of the air). Every Lithium battery charging IC will have a smart charging ...

Technical Lithium Polymer batteries, such as those used in the iPhone, are a very well understood battery chemistry and use specific chargers to manage their charging. While the latest charging ICs Apple uses are proprietary (they work with Dialog for their power managment ICs) it is unlikely that Apple performs a significantly different charging process ...

As someone who works for a battery specific retailer and is asked this question a lot, the answer is "it won't hurt it in the short term, but in the long term it will shorten its lifespan." Between your phone's charging system and the internal circuit board built into the battery itself, there are enough layers of protection that will prevent either your ...

Leaving the iPhone to charge overnight doesn't affect your iPhone drastically. As phones are very smart, once it gets fully charged, it knows when to stop the current from coming in to protect the phone from overcharging. But there are also some reason which can affect your iPhone plugged in overnight, this can leads to slow down the lifespan of your iPhone. ...

I don't know if there is a software way to do that, but there is an hardware way: Use an unpowered USB cable (some company makes it, targeting audiophiles), might need an adapter to male lightning. Tape/Remove the power plugs on your USB cable. Also, not exactly an answer to your question, but maybe to your use-case: Build a binary, then export it to ...

No it does not. Nightly charging is the norm today for many people, and unlike older technology from a few years ago, today's lithium ion based batteries use newer technology and battery life is not damaged with nightly charging. All batteries wear out eventually, but unless you are charging multiple times per day, your battery is likely to outlast your ...

No, it's not harmful. Modern phones are smart enough to stop the electric current when fully charged. That may have been a problem before lithium-ion batteries, but nowadays you shouldn't have to worry about it. However, if your iPhone has a case that doesn't allow heat to escape very well, it might be better to remove the case to avoid overheating. ...
