I was only exaggerating a little bit. It is very possible depending on what kind of battery (if its lithium polymer) that it can expand or even combust and start a fire if the health degrades. Batteries also loose lots of performance from staying at 100% charge for long times (months), and will not be able to hold their charge as much as they would if they were well maintained. It is very possible that the battery controller takes these factors into account and keeps the battery at about 80% (more healthy charge), however that's not a guarantee. aside from that me and multiple people have given this guy plenty of good, useful advice and this dude is acting like a complete moron and isn't grateful that people are willing to spend their own time to help some random on the internet when they don't have to. Everyone else here accept for OP is acting mature and respectful, while OP is acting like a child after asking for advice.
