here is additional information. I used Map following mode of roam3 at that time.
A new fw has been released 
- Added: Performance and battery improvements
7th May 26 16.10 BST
Checked as follows:
Roam 3 WH49 - no update since last year
Wahoo App Android - 3022231 - I suspect may have been updated last few days.
Just completed a 28 mile today, 2h 45min riding, 3h 57min elapsed with Roam 3 still running. From 100% at start, upon return battery is 80% with Auto max backlight, connected to Wahoo app, Varia radar, Tickr, Cadence sensor and wheel sensor.
So almost 4h used 20%.
Is the update you posted about for Wahoo App ?
i dont think you read it correctly
i understand it as following:
wh49 - major version of the roam3 device. hasnt changed recetnly
302231 - minor release of the roam3 device, receives updates as per Release Notes page, every few weeks.
i dont think any of them has anything to do with android/ios app.
my feeling is still that mid april minor update had detrimental effect on the battery, which was apparently recognised by wahoo team and 2weeks later they tried to fix it (with the 302231 minor release)
all of above is my understanding, so i might be of course wrong 
Just checked Wahoo app version in Android on my phone, currently version 6.83.0.
So, looks like you’re correct. Checked release notes and WH49-302231 date 5 May 26. I suppose Wahoo may use WH** for firmware where reboot needed and six digit number for software that can easily update?
It’s a pity their release notes never describe the full story. No mention of detail problems fixed, just “bug fixes, stability improvements”!
Seems to have been pulled out?
I took a screenshot and that was version 302241, listing performance and battery improvements.
When I went to update last night the only version avalaible was 302231, where they’ve added Komoot live sync. No mention of battery improvements.

I think it’s closer to WH49 being the OS version and 302231 being the UI version, but yeah.
WH49 will change to WH50 or something when a fix happens that is real deep, stuff that affects interactions with the hardware. Those are different for the different devices - Roam 3 has WH versions, Ace has WG versions, etc.
They all share the same current software version, 302231.
Wahoo support:
"I have been talking with our hardware experts, and I have been assured that the battery drain issues are indeed software related, and they are aware of the issues.
I’m sorry for your experience, but I have been reassured that this is a hot topic that will be addressed in a future update."
So Wahoo’s own support would suggest we’re stuck for now with devices with battery life that is way below advertised spec, and barely fit for purpose.
“for now” is the key part of that phrase. Sounds like they’re working on it.
Interesting take. Given this thread started 6 weeks ago (30 March), does that give you confidence? Is it a reasonable expectation that buying a Roam 3 would mean having a premium and stable device which meets its advertised spec, vs dealing with what feels like a beta-test software platform?
I mean it was good for like a year, they broke it in software recently, and said they’re working on fixing it.
Sounds like a case of fixing one problem or adding a new feature to then create a new problem. Given the recent announcement about Komoot route updates during a ride, could this new feature be the cause?
Phone running Wahoo app will already be connected by BT LE. If by chance WiFi is enabled, considerable increase in power consumption?
BT LE with same poll rate but increased MTU size for increased data transfer to support route updates could also increase consumption.
Just checked for Roam 3 which has a WH## firmware:
ELEMNT WH49-302241 - 13 May, 2026
- Updated: Performance/Battery Improvements to address recent battery issues
ELEMNT WH49-302231 - 5 May, 2026
- Added: Komoot Live Sync feature
I’ll update and test.
So far this looks much better for me, hope it works for everyone else.
I’ve done 6h2m with battery dropping from 100% to 66%. Let’s see if it keeps it up.
Live track, all the sensors, backlight always on (not max).
As users we are the ultimate testers of a software release. No idea how much beta testing has been done by the Wahoo software team. Its a complex product with lots of integration variables. Hopefully, they have a good rapid software development process with automated test harness, or a team of 50 beta testers who went on a long ride yesterday?
Its a pity that release notes are so brief, with no reference to reason for problem or software module fixes. That information would be useful for integration testers and users looking for non-regression, i.e did fix break some other function.
Often a fix can have knock on consequences.
To be frank, as a developer, the sheer volume of bugs and things breaking in Wahoo software on a monthly basis (not just head unit firmware) makes me think there is not much testing in place.. or a lot of pressure from higher up to ship on tight deadline.
Unfortunately the battery drain continues even with the latest fw 
Yesterday it was 15% over a two hours ride with no navigation
Hi vjakub, just to be clear, do you mean it displays 15% remaining after 2h ride, i.e. was 100% at start and after 2h reads read 15%?
Did the Roam 3 feel warm at end of ride (assuming you’re not riding in strong sun, that would heat up the Roam)?
FYI - I’ve no idea what’s inside Roam 3. However, judging by Roam size I’d guess Wahoo could squeeze in two Lithium Polymer pouches each 3.7V (maybe 800mAh), series connected with BMS charge control. Each pouch a bit less than 2.96Wh capacity. Down to 15% capacity, rough calc at 2.5Wh dissipation within the Roam. I think it would feel warm to touch, maybe hot?
