In 15.1 battery drain so much faster i done a lot of customisation to reduce battery drain but its keep draining

i done limit frame rate

Reduce motion

background app refresh stopped

location services turn off which one is not useful

reset network settings

and many more but still keep draining

even I restored my phone as well

i think ios 15.0 was much batter than ios 15.1

Me too, the iphone is consuming a lot of battery since the update. I’ve updated two XS MAX and one XR, and all three have the same issue. Battery health’s are 100%, 97%, 89%. Moreover, since I updated my Apple Watch Series 4 and 5 to the latest watchOS 8.1, both have lost more than 10-15% of battery life, and both have the battery health at 99%. No soft reset/restart nor switching the devices on and off has sorted this issue. It seems that Apple will have to release an new software update very soon as so many have battery drain issues having different iPhones and also the same happens with the Apple Watch.

I agree I do believe there is some type of pre-designed drain that Apple have worked into the software. The battery used to work great but they probably realized that not many people would buy new batteries so they’ve organized a systematic battery drain. My battery no matter what the usage seems to go down the same level and I end up at the same level at the end of the day. I.e. about 10%. It is actually pretty shocking that they are getting away with this. I have a iPhone max pro 12.

Time to time the same issue comes again and again after iOS updates... :( I have the same issue with iOS 15.1 (had it with some iOS 14.x, don't remember exactly) and there is no specific app which is shown as a battery eater (and I don't use Safari at all): so, the battery is drained by some system processes. It would be great if Apple published their update ONLY AFTER THEY TESTED BATTERY LIFE AND RESOLVED BATTERY DRAIN ISSUE IF FOUND.

I’ve got exactly the same problem, been running 15.1 for about a week after updating to it straight from 14.8 , I’ve been waiting for reports of any bugs in the initial 15 release before updating after not seeing anything obvious of concern I decided to take the plunge and update now wish I hadn’t


i’m running an iPhone se 1st gen with a battery health maximum capacity reeding of 77%


for the first week I had no problems at all , but since yesterday battery drain has been abysmal from 100% charge gone 88% in the space of half hour and instead of the indicator dropping 1% at a time it’s dropping around 6% in one ie 1% drops every 2 seconds


I always use low power mode to last me through the day but since last night the indicator isn’t dropping at all when in this mode and when I take it off it drops about 20% or I have to restart or power down for the gauge to reset


Apple really needs to sort this out as I fully believe it’s a bug in latest update, I’ve turned off background app refresh, but that hasn’t seem to worked and don’t know what else I can do?

Just to update everyone on this thread on my ongoing dialogue with Apple Support. Following a conversation with them, engineering had recommended that I charge my iPhone 12PM fully to 100%, and then use normally but take the battery to 1%. Then repeat that process and then charge and use normally and then send them screenshots of the last 24 hours of battery usage. That was all completed and submitted and the last set of logs are currently being reviewed by Apple engineering. I have also provided them a link to this community page so that they can recognise this isn't an isolated issue. I have a callback currently scheduled with Apple for next week where I'm hoping to get some more information after they've analysed the logs. From the description that I've provided, my phone is heating up directly where the motherboard for the phone is (i.e it's not the battery itself that is running hot - it's the processing). What I've also observed is that it runs hotter quicker when I'm using apps which are not predominantly on device i..e going through eithe Wi-Fi or mobile network (through the mobile network it runs hotter quicker). I'll update this community thread when I have further news.

It is not just Safari, apps on ios 15.1 (or any iOS 15) are power hungry. Drains battery fast. I am using iPhone 11 and its just 4 months old. Should have stayed on factory shipped version of iOS 14. If apple is allowing users to stay on IOS 14 then it’s only logical to keep iOS 14.8 signed so that iphone owners can continue using iOS 14. iOS 15 is the problem.

I had same problem with my iPhone 12 Pro Max after upgrading to iOS 15.1. After troubleshooting with online support and then at the genus bar, we decided to perform a device reset but kept the data on the device. Since then I’ve restored my phone’s normal battery life of practically a full days use like I had before. Hope that helps someone else facing this issue.

I’m traveling right now, so I have to plug into the car for GPS and CarPlay a few times a day, but between those short charges the battery drain on my 11 Pro Max seems to have slowed down significantly with having “turned off the apple news widget” and having done a “reset network settings”.


I might lose 25% with 2.5 hours of continuous all on-screen use, but then when I gently use it for an hour total over the next 3 hours it might only drop 2-3%. The hour after light use I saw 1% drain when it had 13 minutes of screen-off activity during an hour. Tile is also not using as much screen-off battery as before, so that I might lose 1% per hour with location always on. My 6 AirTags and Find My are not draining my battery at all.
