I don't know how those apps decide, because my kaput 5S battery still gets 85% from them ... when it barely holds enough to last half a day's usage. If I don't use it it's very good :) but as soon as I use it, the battery drains very fast.

I read that it makes no difference. It has x cycles in its life, whether thats all full charges or double half charges.

A higher amp charge makes no difference as the phone decides what amps to draw, so on a 2.1A iPad charger it will still only charge at 500mA

As to keeping it on 100% a lot, i.e. sitting on a charger when already charged, I'm not sure, so I'd believe @1eStar

If you drained it fully (not recommended as a habit), I think that corrects any battery miscalibration

When I plug the 5W charger, the app says charging at 1000mAh

When I plug the 12W charger, the app says charging at 2400mAh

FWIW

All that means is that the phone isn't the limiting factor in those charging equations - the chargers are. Put it on a 50W maximum output charger and you'll find it will peak and hold at the design maximum.

I don't pay any special attention to mine, in fact it usually sits on 100% all day as it's plugged in to my Mac. Health is still in the 90% range according to battery apps.

I'm sure Apple have implemented some smart hardware/software tech to manage the charging.

I take this assumption too these days. If there's something simple like stopping charging the battery when it reaches 100% surely the phone's firmware would stop it.

I used to stress about this sort of thing but after several times of leaving my phone at home to avoid it dropping below 20% i figured what's the point. If I can't use the thing when I need it I might was well put it back in its box. These days I charge overnight every night so it's ready to go the following day.

I have two iPhones, my old 5c for personal stuff and work phone for work

The 5c I purchased not long after they came out, and the battery still lasts me a day. I certainly don't treat it nicely, it's been cooked in the car while running gps and charging, kept on charge with external battery while sitting in a back pack pocket on flights, tramps etc, repeatedly run down to zero in countries with next to no reception.

You're not on Atlantis anymore, Duncan Idaho.

That's what I've been doing. Charging overnight. But I think I'll use the 5W charger, it's not that hard to do.

I just go online and buy a replacement battery for about $10 NZ or so and problem solved.

That is, of course, why I am keeping my Galaxy S5 around for as long as I can.

I thought about it, but the risk of setting fire to anything it touches (inc my man bits) put me off the $10 ones.

Then I'm sure you'll feel much better about the risk when buying the $10 one from a local retailer for $40 or more.

I don't buy the $40 either. In fact I bought another phone. But at trademe low ball prices.

I recall reading somewhere that Apple had moved the smart charging capability from the phone board to the cables, starting with the 6. This meant the cables need to be MFI'd, and listed as 'compatible with 6, 6s, 7 etc' - to prevent overcharging etc.
