HSR 3.7 release time, preload, and maintenance details

It’s almost time for our ultimate clash with Irontomb in HSR 3.7. It’s a battle with truly cosmic stakes, as we’re fighting to keep The Destruction from landing a lethal blow against the entire universe on top of trying to give our friends from Amphoreus a future.

While the latest Myriad Celestia Trailer has indicated a bittersweet outcome of the showdown for Amphoreus, we’ll see what kind of miracle the Trailblazer and Cyrene, who’ll be on the HSR 3.7 banners throughout its entire duration, can cook up.

Update 3.7 also has several quality-of-life improvements and new Planar Ornament sets in store.

Here are all the details on the Honkai: Star Rail update 3.7 start time and server downtime.

HSR 3.7 – server downtime

The HSR servers are scheduled to go offline on November 5, 2025, at 06:00am (UTC+8) in preparation for update 3.7. Here’s what that means for your timezone:

• November 4, 02:00pm PST
• November 4, 04:00pm CST (Central)
• November 4, 05:00pm EST
• November 4, 07:00pm BRT
• November 4, 10:00pm GMT
• November 4, 11:00pm CET
• November 5, 03:30am IST
• November 5, 06:00am CST (China)
• November 5, 07:00am KST/JST
• November 5, 09:00am AEDT
• November 5, 11:00am NZDT

The Honkai: Star Rail servers are estimated to be offline for a duration of five hours, after which players will be able to log in once again and start exploring the content of Version 3.7.

HSR 3.7 – release time

HoYoverse doesn’t usually need any more time than the scheduled five hours, so here’s when Honkai: Star Rail update 3.7 should be available in your timezone if all goes according to plan:

• November 4, 07:00pm PST
• November 4, 09:00pm CST (Central)
• November 4, 10:00pm EST
• November 5, 12:00am BRT
• November 5, 03:00am GMT
• November 5, 04:00am CET
• November 5, 08:30am IST
• November 5, 11:00am CST (China)
• November 5, 12:00pm KST/JST
• November 5, 02:00pm AEDT
• November 5, 04:00pm NZDT

Each hour of server downtime will be compensated with 60 Stellar Jades, so expect 300 Jades overall to come your way. In case maintenance takes any longer than planned there were bugs in the previous version that affected the player experience, another 300 Stellar Jades will be up for grabs.

Make sure to check your in-game mail and claim your compensation inside a timeframe of 30 days following the update — otherwise the currency will be lost.

HSR 3.7 – preload

The preload for Honkai: Star Rail update 3.7 on PC, iOS, Android, and PS5 will go live on November 4, 2025, at 06:00pm (UTC+8). Here’s what means for your timezone:

• November 4, 02:00am PST
• November 4, 04:00am CST (Central)
• November 4, 05:00am EST
• November 4, 07:00am BRT
• November 4, 10:00am GMT
• November 4, 11:00am CET
• November 4, 03:30pm IST
• November 4, 06:00pm CST (China)
• November 4, 07:00pm KST/JST
• November 4, 09:00pm AEDT
• November 4, 11:00pm NZDT

The preload will enable you to get the majority of files required for the update downloaded early, minimizing the time you need to get back into the game on patch day.

HSR 3.7 – download size

The download size for updates in HoYoverse games varies depending on the device you play on as well as the language packages you have installed, but here’s how large the files should be on average for Honkai: Star Rail version 3.7:

• PC: 5 to 6 GB
• Mobile: 2 to 3 GB
• PS5: TBD

Always make sure to have extra space on your device beyond the sheer download size, as the game will temporarily need some additional free storage to unpack all the data before installing the update.
