It's a beautiful and very fast phone, and I absolutely adore it, but the lack of a swappable battery does concern me.
I have a habit of charging the phone overnight, and considering it charges from empty to full in just 2 hours, I'm wondering if this is a bad practice. This is what I envision happening.
1) The phone reaches full charge. Charging stops.
2) The phone discharges very slightly, charging begins again.
3) Goto 1 until unplugged from the charger.
Will this result in a problem in the long term?
In theory you would think that's how it would work. Honestly, I don't know though. I use the Samsung Wireless Charger on my night stand. The way it works is, when it's full charged, it shuts off and will not charge again until the phone is removed and replaced on the wireless charger. I know that doesn't answer your question directly, but if you have the Samsung wireless charger, then leaving on the charger over night would only charge once. With that being said, some could argue that wireless charging generates more heat which also can degrade battery life. Basically, you can't win. LOL. If you have some time, I recommend these two articles.
