Just ignore that feature entirely. I've had iPhones that still hold a decent charge after a decade! I got a PowerBook G4 that has an ancient battery still holding enough charge to play an MP3 playlist hours long!

While all my Androids have either flat batteries or are swelling after a year.

IMO that 'battery health' feature is only good for one thing: Disabling the performance throttle. That was a big complaint from past iPhone users for years. But just ignore the number. My mother has a 6S where it's showing like 65% under 'battery health' but she's still getting a couple days between charges.

That works thanks for explaining.

Mine's at 98% and it's fine.

If you come to think about it, you'll be putting around 400 cycles on that battery by the time it is 1 year old. Since it probably has around 60 cycles by now, 99% is probably an overestimation.

I think it’s fine. Nothing to be concerned about.

Users post Battery health figures on these boards and some have 100% after five/six months etc and it can make other users paranoid or concerned they have lemons when in reality it’s just the iOS software guesstimating figures based on individual usage patterns.

Chances are if you halved your daily usage for a few weeks, followed that with a factory reset your phone would display 100% again. Basically you could manipulate the software predictions or accuracy with a temporary change to user habit

FYI you can 'reset' the 'battery health' on an iRobot Roomba by merely pulling the battery for an hour and placing it back in. It resets it to 100% 'new'. Doesn't do jack for the actual run-time however lol

Battery Health allows for you to disable the performance toggle but I am guessing it's just there for warranty/lawsuit claims. More like a warranty.

Well with all the complaints and panic over 'battery health' I can see it coming. Maybe not officially but among the customers. When I had an iPhone 4 I was unaffected by so-called 'Antennagate' (well it probably helped that it was in an Otterbox Defender but I digress) but that didn't stop endless complaints about it.

All the complaints? Doesn't really seem to be anything more than what has been more or less the usual essentially.

There's currently a few active threads here about it. People are nervous it's dipped to 98%. It doesn't amount to anything. Mom's 6S has 65% and still gets decent standby times of a day or two--as mine does and the difference is mine is still showing 100%. The number is meaningless. People are panicking over nothing.
