I have had my iPhone 8 since Black Friday 2019, so the 29th/30th November. It’s usual trend is to decrease in battery health 1% every month; I have been told this is normal. What is not normal, however, is that the battery has gone down by 2% in the last two days. My battery health is at 92% and my phone is only about 7 months old now. Should I be worried about this?

Hi, celine322.
Thank you for reaching out on the Apple Support Communities. We understand that you’re concerned that the capacity of your iPhone battery has reduced faster than expected over the last month.
Your iPhone battery capacity is calculated by charge cycles. A complete charge cycle occurs when an amount that equals 100% of your battery charge has been discharged. Have you been charging your battery more frequently recently?
If so, review your battery usage to see if you can pinpoint a specific app or process using most of your battery resources. We also suggest following the suggestions to improve your battery life here.

celine322,
We totally get being confused about the battery life on your iPhone. Let’s take look at your battery usage to see if we can determine why your capacity is reducing.
If you go to Settings > Battery, do you see any suggestions? Some examples might be to Reduce Brightness, Enable Auto-Lock, or Auto-Brightness. If you do, try enabling the suggestions here.
Then tap “Last 24 Hours” and review the “Battery Usage by App” section. Do you see an app or service using a large portion of your battery?

Sorry about that, brenden. I didn’t know anyone replied. No, I have not been charging my phone more than usual. It has actually gone down one more percent last night. I’m extremely confused because nothing about the charge cycles has changed!! I’m also very worried about my battery. Thank you though.
No, there are not any suggestions. The app taking up the most battery is Instagram taking up 26%. Which is normal as I am on Instagram quite a bit. Thank you though!!
Battery Health decreased 2% in less than two days. Should I be worried?
