How do you "carefully charge" a phone? And by how much would that extend the battery life? I am on my second "flagship" phone that is down to an hour of battery life after 2 years. This time I will attempt to replace the battery because these things cost way too much to replace every 2-3 years.

You can get it replaced for $29, which is cheaper than doing it yourself in most cases: https://www.apple.com/iphone-battery-and-performance/ https://www.apple.com/iphone-battery-and-performance/ If it is a 6S, you may be able to get it replaced for free: https://www.apple.com/support/iphone6s-unexpectedshutdown/ https://www.apple.com/support/iphone6s-unexpectedshutdown/

It's almost as if you have no idea what you're talking about and are just making stuff up. The top reply proves that.

Supposedly, lithium ion batteries like to be totally drained before being charged and then charged to max before being unplugged. I personally find this regime difficult to attain with phones because I'd rather not have the phone die while I'm far from a charger, so I often start charging when it is at 20% or so. And when I have to go to work, I unplug the phone, even if it isn't at 100% charge. I think most people do similarly, but the battery would really prefer you use it all the way up and charge to max. I think this is what the GP means by "carefully charging."

  Isn't that regime for old NiMH batteries that had the "memory" effect? I thought for lion it's the opposite, never fully charge and never fully drain.

    Yep, fully draining just wears the battery down faster.

  Not true. Actually, the less capacity is utilized (of theoretical maximum), the longer will be lifetime of li-ion batteries. For example, if kept between 20%...80%, they may last for 10x more cycles. That's why electric cars' batteries does not need to be replaced every couple of years.

    Interesting, thanks for correcting me.
