On days with mild use, I’ve 70 % left by bedtime. Once 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 %. I would 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 10.5 hours of screen-on time.
This is likely to be the very best battery life on a flagship smartphone right this moment within the US, particularly while you pair it with the extremely quick recharge instances. OnePlus stays one of many solely corporations to incorporate a charger within the field—principally as a result of it is the one approach to make the most of its SuperVooc fast-charging expertise. I used to be capable of ramp from 15 to 80 % in half-hour (50 % in quarter-hour). It is onerous to fret a couple of lifeless telephone should you do not thoughts preserving 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. Should you’re a fan of wi-fi charging and are particularly excited by Qi2 smartphones that use magnets (like Apple’s MagSafe) for extra handy and quicker charging, you may be dissatisfied right here. The OnePlus 15 helps wi-fi charging, however solely the usual Qi expertise. OnePlus is promoting magnetic circumstances as a salve, however in contrast to Samsung’s present crop of top-end telephones, this does not even flip it right into a Qi2 Prepared telephone. It’s going to solely cost at sluggish 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 gadgets shortly.)
The beefy battery and super-fast wired charging might outshine the lackluster wi-fi charging, however now it is time to discuss concerning 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 wonderful. In a Geekbench 6 check, 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).
