How long to charge?

Yes. But ...

If you want the battery to last as long as possible, never let it drop below 40%, and don't charge it past 80%. That won't give you 2 days of Screen on time, but it will give you the longest battery life you can get. (Lithium batteries weren't chosen for toughness, they were chosen because a) lithium is the lightest metal at normal temperatures and b) a lithium polymer battery can be shaped into almost anything - like a very thin battery - which is what people want, light and thin.

It's taking 2 hours to charge and that's from like 30-100. Is that normal?
Do you have fast charge enabled. It can usually charge up faster than that, if you'd like it to. I've been fast charging as long as it's been around and havent noticed ill effects. I charge usually to 100 % or sometimes less if I'm in a hurry.

I think? How do you see if it's enabled. I think it says fast charging but still takes long.

If I'm not mistaken, the charging speeds vary depending on your battery percentage. At lower percentages, the speed is a lot quicker and it slows down once it gets better closer to full.
So, 30-100% might be not take much longer than 0-100%.

Man i hate those tips. I'm not saying that they are false, I believe they are true, but it's like "hey, pay 100% of the battery capacity but only use its 40% capacity for longevity reasons" so 4000mah turns into less than 2000mah, I then should have a 8000mah battery to get it to last at least a day using only its 40% capacity. It's bullsh*it! You'll never get to enjoy the battery at its all. It is like buying a guitar an only playing with 4 strings and save the rest for longevity reasons. It's laughable. Enjoy your battery man. By the time it's dead or its performance has dropped drastically, for sure you have change your smartphone.

I just charge when I need to. I've always done this and haven't had any issue with battery degradation whatsoever. I usually charge once I see it's 15% or below, sometimes earlier depending on if i would need to have a full charge (when I have to be out of the house).

I have a wireless charger and it sits on the charger all night. The battery then lasts all day with heavy use. If I didn't have a wireless charger I would plug it in overnight, although it sure doesn't take long. Samsung says to use the original equipment charger for a fast charge. I don't know why but a cheap charger doesn't charge as fast and the phone is always quick to tell me that as well.

lol who actually has time to monitor a cell phone that closely, that's ridiculous. Like saying to get the best gas mileage, drive 35 in a 55 but don't let the people flipping you off and trying to run you off the road bother you.

Lol. Imagining me in my charger, driving 20 under the limit. I'm physically incapable of that.

But, I do see his point. I'm sure that would extend the battery life to a point, but ita certainly not practical for me and I like to use my device not keep it charging and out of use etc. May work for some, but doubt the majority.

Fast charge is really only good from 0-60/70%, or something like that. It enables you to get a quick charge in a very short amount of time. Anything from 70/80, up to 100, is pretty normal speed. 0-50% might take 20 minutes, but then it may take 40 for 50-100%. Something like that.

Fast charge should be on by default. It's under Battery settings.

Also, you must be using a fast charging plug. I don't know really, about the cable, but the USB plug that goes into the electrical socket must be a fast-enabled as well. A standard one for 4$ from the local gas station isn't going to do the trick.

Also, Fast Charging will make your phone/battery a little warm. Some people recommend turning it off to keep your phone cooler, thus improving the longevity. /shrug.

See this is the other crap that makes me sick to my stomach, having to make sacrifices for a something that's supposed to be a work horse. F that, it's the most expensive phone on the planet. Run it at full brightness, high performance mode, no exceptions, 24/7. need to reboot it every so often, fine... that should be about it. If it can't handle that, move on.
