OnePlus 15 Review: A Phone With Two-Day Battery Life Leave a comment

On days with gentle use, I’ve 70 p.c left by bedtime. After I spent extra time on the cellphone, utilizing it for music streaming, navigation, and Instagram Reels-ing, I typically 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 and a half hours of screen-on time.

This is perhaps the most effective battery life on a flagship smartphone right this moment within the US, particularly once you pair it with the extremely quick recharge occasions. 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 reap the benefits of its SuperVooc fast-charging know-how. 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 laborious to fret a couple of useless cellphone for those who 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 at all times a compromise someplace. For those who’re a fan of wi-fi charging and are particularly occupied with Qi2 smartphones that use magnets (like Apple’s MagSafe) for extra handy and quicker 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 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 Prepared cellphone. It’ll 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 rapidly.)

The beefy battery and super-fast wired charging might outshine the lackluster wi-fi charging, however now it is time to discuss in regards to the second most spectacular feat of the OnePlus 15: efficiency.

Energy Play

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 check, the OnePlus 15 is formally the primary cellphone to go 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 typically extra environment friendly).
