These battery life claims are impressive. I'd like to see how they hold up in the real world.
- judge2020 5y agoEvery year they make the same claims, but in recent year that I've had an iPhone (8 Plus -> 11 -> 12) it will last all-day for 4-5 months before needing charging in the car (especially while doing multiple things like Music, Maps, and perhaps mobile food ordering [without CarPlay]). The chemical properties of li-ion seemingly can't be overcome without making the battery module physically bigger, which is why my next iPhone (14 or 15) will have to be the Pro Max version.
- alibert 5y agoFrom my anecdotal evidence (+ research on the web), charging in car is the worse thing you could do to any phone. * charging in hot environment * charging in GPS mode with sunlight on the phone (very bad) * unstable current due to the way car alternator work * power charging with QC or USB-PD As a result, I have avoided all this and only charge with a genuine "low" current standard 2A Apple charger at night. Only exceptionally I will use a QC charger. I also avoid wireless charging with the excess heat. It has been 6 months and my battery health is still at 99%.
- photojosh 5y agoTotally agree with all of this except "unstable current due to the way car alternator work"... as an electronics designer, if this is an issue then it's a really poorly designed car charger. CarPlay alleviates a lot of these issues fortunately.
- alibert 5y agoCould you provide any advice on brands for a good car charger? Thank you.
- photojosh 5y agoI'm still using one I bought probably 10 years ago; it's a Belkin with 2x2.1A outputs. But I'd look at Anker too (have been happy with their wall chargers and headphones). If I were buying new I'd probably get USB-C now.
