iPhone X iPhone X owners Post you battery health after one year of usage

Launch day. Was at 99% until about a month ago. I checked it after seeing one of these threads and saw it was suddenly at 94%.

Seems odd it dropped that much in a couple weeks.

Mine was reading 97% on iOS 11.4.1 around a week before I upgraded to iOS 12. After the upgrade, it dropped to 92%.

I’m guessing the indicator is more accurate in iOS 12. Wasn’t it still in beta in 11.4.1!?
 
92%

Bought at launch date, been using a 5W qi charger every night.

I definitely believe a 100% battery is better than a 80% battery, but can we believe that e.g. 94% is better than e.g. 92%? I just don’t believe the test is that accurate. Also given that CoconutBattery have for me and others reported different % health compared to Apple’s report.

Bought on launch day. Currently at 88%. Can definitely tell the difference now as the phone struggles to last all day whereas before it could easily do it.

When I read the results here, I have the feeling that it makes no difference at all how you treat the battery. Just a matter of luck.

Indeed, I have tried to see a connection between charging and battery health, but can't find a connection (in this thread at least).

I bought my X at launch date. I read an article before about Lithium lon batteries and it was specifically stated that in order to have longer li ion battery lifespan, always charge lithium ion batteries not to reach 100%. Don’t let li ion batteries drain and if possible always don’t go below 25% and don’t charge above 85%. Lower temperature and lower volts while charging is good to the battery too. I followed this charging routine since then.

Yep according to laboratory tests i read before. Charging method affects battery life and not just battery cycles.

My wife is a heavy user. Most nights she ends at 20% or so. A lot of the time she charges during the day. She uses the camera in the sun for long periods of time. Very stressful for the battery. Charges every night to 100%. Her launch X just hit 99% within the last few weeks. Babying a cheap battery isn’t worth it. Been there, done that.

Whilst it’s great that you still have 100% battery health following this routine, it means only 60% of your iPhones battery life is useable to you. If that works for you, then that’s great, but it just isn’t feasible for a lot of people.

My battery health is at 92%, but my useable battery life is a lot better than yours as I have no qualms about running it down to zero.

Well it’s up to you what you want to do with your battery. My post says “if possible”. If a user has no choice, a user can drain their battery lol. Everyone has their own needs.

So you don‘t charge overnight?

Honestly, I can’t tell because the 10% that I’m plugged in is either when I’m plugged into the USB in my car or into my iPad charger if I need to charge quickly.

I am a hardcore Pokemon Go player, so there are days where I’ll fully charge and discharge my battery twice, and the game can be processor intensive at times, so my phone has gotten very hot on occasion. This is the reason I suspect my lower battery health after about a year.
 
A lot of you won't agree with me but Ive been noticing consistently that its the people who use wireless charging heavily have around 90%.

Please keep in mind heat is the #1 enemy of lithium batteries, If your phone gets hot/warm while wireless charging thats a good bet its degrading your battery.

Also, we should be posting our location or continent, because outside heat does play a role on battery degradation.

iPhone X IOS 11.4, from mid December 2017, battery health according to apple is 99% but this is more accurate.
