Like a school scholar emailing their project to the professor at 11:59 p.m., OnePlus rolled out its Put on OS 5 replace to some OnePlus Watch 2 and 2R customers on December 29, sneaking below their self-imposed end-of-year deadline. And as you may anticipate, this last-minute replace has been inflicting issues since then.
The OnePlus Watch 2 and Watch 2R, each launched in 2024 working Put on OS 4, have been initially presupposed to obtain Put on OS 5 between July and September 2025; solely after Android Authority requested concerning the delay in October did the corporate say the replace would arrive “within the close to future.”
Now, some OnePlus Watch homeowners have obtained the replace, although not everybody; my U.S.-based OnePlus Watch 2R, for instance, nonetheless reveals Put on OS 4 and the Might 2025 safety replace. However this is perhaps a blessing in disguise, given the replace’s impact.
This Reddit thread and several other OnePlus discussion board posts (right here, right here, and right here) have talked about that the replace is inflicting extreme battery drain. The Watch 2 and 2R often lasted about three days in good mode earlier than the replace; now, some customers say it will not final a full day, even after making an attempt manufacturing unit resets and different fixes.
“I am totally heartbroken and pissed off with the drastic battery drain concern plaguing my OnePlus Watch 2 following the Put on OS 5 replace,” says one person. “My OnePlus Watch 2 now plummets from full cost at 1:00 PM to a essential 10% by 11:00 PM on gentle utilization.”
“Earlier I used to get 2.5 days simply with most settings on (at the least 2 days)… Now barely getting 1 day,” says one other person. Somebody responded that his drain wasn’t fairly as dangerous, however that he’d gone from 3–4 days earlier than to “a strict 2 days” now.
A number of customers level to particular apps inflicting the drain, just like the Climate app, Play Retailer, or “Put on OS” itself, however the selection suggests this can be a system-wide concern moderately than one app inflicting issues.
What makes this replace particularly irritating to customers is that inventory Put on OS 5 is (A) a really refined replace with few notable adjustments and (B) presupposed to make Put on OS run extra effectively, because it did on Pixel and Galaxy Watches. The OnePlus Watch 3 has run this model since April with no points, making this unoptimized replace on last-gen fashions disappointing to see.
Any model can push a buggy replace, however two weeks later, I would have anticipated OnePlus to both roll it again or announce a timetable for fixes. As a substitute, OnePlus hasn’t made any official announcement, from what we have seen. My colleague reached out to OnePlus concerning the replace just a few days in the past, however we have but to listen to again.
Having advisable the OnePlus Watch 2R as my greatest finances Android smartwatch choose, totally on the power of its battery life, this replace is deeply regarding to me. OnePlus must show that its promise of two Put on OS updates and three years of safety updates is not simply empty rhetoric, and that it will correctly help these watches.
As it’s, it is notable that the latest OnePlus Watch Lite skipped Put on OS completely, utilizing a proprietary RTOS like the unique OnePlus Watch.
