whats the proper way to charge your battery. I have been on many forums and I always find different answers to charging my iPhone. I was told to charge regularly between 40 and 80% and never charge from zero to a hundred. Never run phone below 20% and never charge to 100% only 80-90%. This seems bizarre to me if anyone could give advice

That was terrible advice, and not true at all.

Charge it when it's getting low. Feel free to charge it to 100%. The majority of iPhone users plug their phone in at night before bed and take it off the charger in the morning at 100%.

Whoever gave you advice did not know what they were talking about.

It was from an article in a news paper from some professor who studies batteries have a read http://www.theguardian.com/technology/2015/nov/04/why-your-phone-battery-is-rubbish

I think the person who posted that many plug their phones in at night and have 100% when they get up the next morning is correct.

Apple put a lot of technology in our devices and plugging them in when you go to bed every night is all you need to do. Cycling your battery from zero to 100% for the heck of it just eats up cycles. I have never done anything special to my battery other than just use it.

Charge it when you need it. That's it. Technology has advance quite a bit from the days of NiCd and NiMh rechargeable batteries.

Life's to short to overthink everything. For probably the last 10 years, I have just plugged in my devices at night and unplugged them in the morning and never had a problem. If my technique causes my batter to age prematurely, we are probably talking about a few weeks of life, one way or the other. Not worth worrying about.

What's the point of having a mobile device if you can only use it in the 40-80% battery region. Ridiculous.
My iPhone goes from 100-1% daily and I occasionally let it run down so far that it switches itself off. If I kept it for three years then I would just spend $20 on a new battery.

Go ahead and charge it to 100% as much as you want, that's really a not a concern. Discharging it down to 0% all the time will however eat up your battery cycles pretty quick.

Some battery testing software reported that my old GS4 had retained 79% of its maximum battery capacity after over 2 years of use. I usually followed the same usage pattern as sunking, I would use it for two days down to 1-5% before plugging it in. The thing with my GS4 though was that it had an easily replaceable battery, iPhones not so much...

It won't make much of a difference to worry about. Say you practice some sort of behavior that does extend the live of the battery a couple percent....is that worth the constant effort?

If cycles matter then it would be best to minimize the use of the phone....sooo why buy a phone and limit your use? Just charged the thing when you need too.

If you use your phone for streaming videos and playing games,you should expect that you will have short battery life with your phone.
If this is a problem for you, maybe a tablet might work better.

Just to be clear... The person who said to charge your phone "little and often" was a Gizmodo tech "expert" whose last article was "19 Things I'm Dying to Carbonate With SodaStream's Magical New Machine", not a professor who has studied batteries. The professors and researchers quoted in the article were discussing new technologies that are coming, not how to extend the battery life of your current system.

I'm in the "recharge when you need to or it's convenient" camp... I plug in overnight, no matter how much charge I have. Other than that, I'm only concerned if I know I'm going to be doing some heavy power sucking while being disconnected for awhile, like using my phone for my golf GPS app for 4 or 5 hours. I make sure I'm fully charged before that.

If any of those charging practices were true and worked it would probably only help if you had your device for 3+ years and only give you a very marginal benefit- like maybe your battery is 1-3% better. Definitely not worth it.
