iPhone SE battery health

Thank you for your reply. I am afraid however that you have missed my point detailed and documented in my post.

I draw your attention to those detail. The gist of the issue is:

after every and each iOS update, the battery health dropped. This is consistent and to me it suggest a perhaps there is correlation between the iOS and battery degradation on an older chip on this first generation SE phone.

Note, even two months of having a new phone and 100% battery health, after an update, the percentage suddenly dropped and it continued from there.

We all know battery health is dependent on many things, usage, extreme heat/cold exposure, etc. This not the case here. Of course you do not know my usage Habib. But as reported in earlier post, I use the phone sparingly, not social networking at all, just occasional phone called, texting and emails. I also look after my device and follow good battery charging practices.

to view the battery health dropping 10% (your observation) in over a year is too simplistic and ignores the main concern carefully documented and reported in my post. It is provided as a knowledge base (not a question) for users some of whom by the way have reported similar battery problems albeit on other newer type iPhones.

Your assumption in “not charging as needed” could not be more incorrect.

in fact each time Apple Support checked the phone as recent as a week ago, and ran ‘battery diagnostics’ (as well as general diagnostics). They verified and pronounced the battery charging bro be correct and as prescribed, and found no issues.

i reiterate that my observation well documented has been that, following each iOS update, the battery health percentage consistently dropped a week or so later. Even one Apple technician at an Apple Store admitted as much to me that the older SE “chip set may not be able to keep with more robust iOS updates.”

i do not know you or your technical acumen but your assumption is quite astonishing.

Please no more reply post from you.

Having read, understood and appreciated your logic and by the way I was aware of the degradation after 500 charge and limitation, I am nevertheless convinced there is a direct correlation of iOS updates and battery health, decline, assuming the reporting software is accurate. Referring to your explanation though, my drop in battery health percentages is not due to just after using the phone for a period of time. But instead it’s consistently just after every IOS updates. In fact it just dropped again upon updating to 14.4.1, a couple of days ago. Further, I was concerned at the outset how only after only month normal use (my documentation) the battery health degraded in such a short period.

Anyway, thank you again for your input.

i was told to continue documenting and reporting though there is apparently no solution as discussed several times with Apple Support. However I am proving this information to the community as there have bee.n others reporting same or similar batter issues albeit with other iPhone models.

Thank you for your reply.

I can only refer to and speak for my experience here. As I have documented, my updates are not 100 or more, they are detailed to several (my earlier post) with timelines and versions indicated, going back to when my phone was brand new with 100% battery health.

If others too are reporting the same or similar concerns, are we all wrong?

Thank you Mr. Finch.

it is refreshing to receive much more logical and informative reply than assumptive comments by others.
