[Poll] Galaxy S8 on Oreo suffering from high battery drain in airplane mode

The Android 8.0 Oreo update brought many new features and enhancements to the Galaxy S8 and Galaxy S8+, but many users have also complained of poorer battery life on Oreo compared to Nougat. Reduced battery life is often a side effect of major updates, but for some Galaxy S8 and S8+ owners, battery life seems to have been affected in an unusual manner after the Oreo update: The phones have begun draining battery excessively when airplane mode is enabled.

European Galaxy S8 units seem to be most affected

Galaxy S8 and S8+ users have taken to the Samsung Community and other forums to complain that their phone now eats up to 20 percent battery in idle with airplane mode enabled. On Nougat, the battery drain in airplane mode for these users was around 1 to 2 percent, which is standard fare for most smartphones when all the connectivity options are disabled. European consumers seem to have been affected the most, and while Samsung’s official forum moderators have said the company is aware of the issue and is looking into the matter, no fix has been offered yet.

Factory resets and cache wipes haven’t helped, either, and it looks like the problem lies in the code for the phone’s modem/radio. Switching to 3G/2G network mode (from Settings » Connections » Mobile networks) before switching airplane mode has been touted as a temporary solution and, of course, one can also simply use Do Not Disturb mode if they don’t want to be disturbed by calls and notifications in the middle of the night.

Complaints about the excessive battery drain on airplane mode have been coming in since March, so it’s high time Samsung offers a permanent solution by way of an update. Maybe the April 2018 security patch update will include a fix, and we’ve asked Samsung for an official statement. We’ll let you know once we hear back from the company and also test one of our Galaxy S8 units in airplane mode to see if the same issue affects us.

In the meantime, you can tell us if you have been facing this issue on your Galaxy S8 after updating to Oreo by voting in the poll and leaving a comment.

Is your Galaxy S8 or S8+ facing high battery drain on airplane mode on Oreo?

My S8+ is running hot, especially when using maps to navigate. Even putting it on the charger it uses more power than it receives. It also causes the phone to run slower too. Have we heard any leaks on if Samsung is going to be fixing this anytime soon? The Note 9 release can’t come fast enough if they don’t plan on fixing it.

AOD and Android system are using too much battery since Oreo. On Nougat I didn’t have AOD on list now it using almost 10% and Android System is using battery same as display. This is poor update. If you ask Samsung 7 months is not enough for good update.

Moi je passerais bien directement a Oreo 8″0 avec mon grand prime sm-g530w. Il semble que ce soit maintenant faisable.

I wont upgrade my S7 edge ever. Battery life has gotton really worse while I was on 6. I’m on the first version of 7. Through my life, update on android, ios, windows has taught me 1 thing. If yoy know you are on good version, don’t update. Never, ever. Update once, factıry reset, use for ever. But everybody has their own opinion.

European S8 here, 0 problems. The battery lasts even a bit longer than it used to last before. I’m running AoD 24/7 as well.

S7 users (like myself) with a 2 years old device (whose battery capacity might have reduced to about 70%) should read this while thinking about having this major update.

Even without airplane mode, my current 1 year old S8 (Android 8) is still draining even with or without Always on display.
