    I recently learned of this feature while Googling symptoms. My battery life has decreased dramatically in last 4 days. First time I figured maybe it wasn't plugged in at night like I thought it was. Nope, next fews days I checked battery percentage when waking up. I don't think it's software since there hasn't been any changes to that (just got the 11.4 notice a few minutes ago, have not installed yet). Anyways, If I got to settings>battery,>battery health (beta), my battery health is at 88% but still performing optimally. Just curious to see what you guys are seeing, and if it's under 100%, have you noticed a life span change? I wake up at 5:45am, and by the time I get home from work at 4:00pm, my battery has been 20-something% all week. This literally happened over night. Before this, it was 60-something% when I got home. Just curious if my battery is on it's last leg and getting ready to quit on me.

    What does battery usage say about it. Has anything different started using a lot of battery power.

    Nope, nothing has changed there. Typical numbers from the apps I use.

    Mine was at 88% too prior to the upgrade to 11.4. iPhone 7 Plus purchased on release date in 2016.

    After upgrading to 11.4 my battery health is now 90%

    I didn't think to check after going to 11.4. Mine went up from 88% to 89%. Whatever 11.4 did, my battery is back to normal and lasting all day again.

    Be sure when you check the battery health %, your device is at 100% charge. It's most accurate then.

    Thanks. I saw your reply last night just before bed and my phone was at 37% and battery health was at 89%. This morning I unplugged my phone at 100% and checked my phone health, still 89%. I’ve had my phone since it came out, so that’s probably about right.

    Last week was weird and I don’t know what caused such rapid battery drain, but it’s back to working normal again.
