There's a couple of advantages of the iPhone versus Android when it
comes to batteries.
First, Apple continues production of older models for several years
after the release so even if you're buying an older model, to save
money, you're likely to get a recent production model where the battery
has not been sitting around for a year or two.
Until recently, Apple's philosophy has been to use older models as their
mid-range models and not produce separate flagship, mid-range devices
(but to produce the SE as an entry-level device). With the iPhone 14,
this philosophy has changed, with the iPhone 14 and 14 Plus models being
mid-range models and the iPhone 14 Pro and Pro Max being flagship models.
With Android phones, almost none are manufactured for more than two
years after initial release.
My iPhones:
11 (First available: 20 September 2019)
Production date: 19 Jun 2022
Purchase date: 11 October 2022
Battery health: 100%
Xr (First available: 26 October 2018)
Production date: 19 July 2021
Purchase date: 7 August 2021
Battery health: 96%
6s Plus (First available: 9 September 2015)
Production date: 6 Nov 2018
Purchase date: 19 Jan 2019
Battery health: 96%
A little disappointing that the 16 month old Xr has the same 4% loss as
the four year old 6s Plus, but I used the Xr as my primary phone whereas
the 6s Plus was not used much, it was bought for me by my employer for
political reasons. I should check my wife's SE2020 which she uses
constantly for many hours per day.
Second, new production batteries are available for many years after the
iPhone was produced. With Android, a phone that's several years old
probably has only replacement batteries that are also several years old.
For all three of my iPhones, it's still a long way until the 80% level
where battery replacement is recommended. I only got the 11 so I'd have
two phones that are eSIM capable so when we travel to countries where
physical SIM cards with a phone number are complicated to buy (like in
China) we have the option of purchasing a data-only eSIM.
