On days with gentle use, I’ve 70 p.c left by bedtime. Once I spent extra time on the cellphone, utilizing it for music streaming, navigation, and Instagram Reels-ing, I usually ended with round 60 or 50 p.c. I might depart 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 perfect battery life on a flagship smartphone immediately within the US, particularly whenever you pair it with the extremely quick recharge instances. 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 expertise. I used to be in a position to ramp from 15 to 80 p.c in half-hour (50 p.c in quarter-hour). It is onerous to fret a few useless cellphone in the event you 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 at all times a compromise someplace. For those who’re a fan of wi-fi charging and are particularly thinking about Qi2 smartphones that use magnets (like Apple’s MagSafe) for extra handy and sooner charging, you may be dissatisfied right here. The OnePlus 15 helps wi-fi charging, however solely the usual Qi expertise. 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 cellphone. It would 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 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 glorious. In a Geekbench 6 take a look at, the OnePlus 15 is formally the primary cellphone to move 10,000 in multi-core CPU efficiency, even besting the iPhone 17 Professional Max. Nonetheless, the iPhone nonetheless had a slight leg up in single-core efficiency (it is also typically extra environment friendly).
