hello there. Firstly, please excuse the following rather long post - I'm just anxious to make sure I explain my query without confusing anybody further.
Since updating to IOS13 on my iPhone SE yesterday I've noticed my battery is draining at an alarming rate. I realize it is getting a bit old now (current maximum performance is 81%), but it's losing life at an incredible rate. For instance, after performing 2 tasks consecutively (clearing my notification centre and making an alteration to my control centre). Following those two simple and quick tasks the battery life had decreased from 17 to 13%.
I have made various alterations within settings in an attempt to save battery life, including switching the screen to dark mode (since I rely solely on Voiceover), I always leave screen curtain turned on unless I need sighted assistance, Bluetooth stays switched off unless I am using other devices like my Bluetooth speakers, battery optimizing is currently turned on, and the device is set to lock automatically after 1 minute of inactivity. I never leave the phone on charge overnight, but each night before bed I make a habit of forcing all apps to close down using the app switcher, Wi-Fi is switched off, and I turn on airplane mode so that I'm not disturbed by notifications during the night.
Before I updated my battery would typically notify me once a day that it was low. Since the update it has started telling me at least twice.
While I understand that there are countless reasons why phone batteries might not hold their charge for long, I am nonetheless a bit concerned that even though mine is getting older, surely it shouldn't be losing charge quite so quickly considering it was behaving fine while I was using IOS12?
I just wondered if anyone might be able to suggest anything else I might try apart from the steps I have listed above in order to conserve battery life a bit longer.
Many thanks in advance for any suggestions; much appreciated :)
