On days with gentle use, I’ve 70 p.c left by bedtime. After I spent extra time on the telephone, utilizing it for music streaming, navigation, and Instagram Reels-ing, I usually ended with round 60 or 50 p.c. I might go away it on my nightstand with out bothering to plug it in, a refreshing change of tempo. Over the course of two days, I hit a tremendous 10 and a half hours of screen-on time.
This is likely to be one of the best battery life on a flagship smartphone at present within the US, particularly whenever you pair it with the extremely quick recharge occasions. OnePlus stays one of many solely corporations to incorporate a charger within the field—largely as a result of it is the one solution to reap the benefits of its SuperVooc fast-charging know-how. I used to be capable of ramp from 15 to 80 p.c in half-hour (50 p.c in quarter-hour). It is arduous to fret a couple of useless telephone if you happen to do not thoughts retaining the cumbersome charger in your particular person (is a folding prong an excessive amount of of an ask?).
However there’s all the time a compromise someplace. In the event you’re a fan of wi-fi charging and are particularly concerned about Qi2 smartphones that use magnets (like Apple’s MagSafe) for extra handy and sooner charging, you will be disillusioned right here. The OnePlus 15 helps wi-fi charging, however solely the usual Qi know-how. OnePlus is promoting magnetic instances as a salve, however not like Samsung’s present crop of top-end telephones, this does not even flip it right into a Qi2 Prepared telephone. It is going to solely cost at gradual Qi wi-fi charging speeds. (You can purchase OnePlus’ proprietary wi-fi charger to fast-charge, however that is a separate buy, and that wi-fi charger will solely recharge choose OnePlus units shortly.)
The beefy battery and super-fast wired charging might outshine the lackluster wi-fi charging, however now it is time to speak in regards to the second most spectacular feat of the OnePlus 15: efficiency.

That is the primary smartphone within the US to make use of Qualcomm’s Snapdragon 8 Elite Gen 5, a processor we’ll see in most high-end Android telephones in 2026. The benchmark numbers are glorious. In a Geekbench 6 take a look at, the OnePlus 15 is formally the primary telephone to cross 10,000 in multi-core CPU efficiency, even besting the iPhone 17 Professional Max. Nevertheless, the iPhone nonetheless had a slight leg up in single-core efficiency (it is also usually extra environment friendly).
