On days with mild use, I’ve 70 % left by bedtime. After I spent extra time on the telephone, utilizing it for music streaming, navigation, and Instagram Reels-ing, I typically ended with round 60 or 50 %. I would 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 an incredible 10 and a half hours of screen-on time.
This may be the very best battery life on a flagship smartphone at this time within the US, particularly while you pair it with the extremely quick recharge occasions. OnePlus stays one of many solely firms to incorporate a charger in the box—principally as a result of it is the one option 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 useless telephone if you happen to do not thoughts protecting 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. If you happen to’re a fan of wireless charging and are particularly curious 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 circumstances as a salve, however not like Samsung’s present crop of top-end telephones, this does not even flip it right into a Qi2 Ready phone. It’s going to solely cost at sluggish Qi wi-fi charging speeds. (You can purchase OnePlus’ proprietary wireless 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 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 go 10,000 in multi-core CPU efficiency, even besting the iPhone 17 Pro Max. Nonetheless, the iPhone nonetheless had a slight leg up in single-core efficiency (it is also typically extra environment friendly).
