The OnePlus 15 Can Ease Your Cellphone Energy Anxiousness With Two-Day Battery Life and Lightspeed Charging

Habit-Altering Battery Performance

At 7,300 mAh, the OnePlus 15 has the most important battery in a contemporary cellphone, and it’s not even shut. It’s 20 p.c bigger than the already large 6,000 mAh battery in its predecessor, the OnePlus 13, and near 50 p.c bigger than the batteries on this 12 months’s hottest Android flagships, Google Pixel 10 Pro XL (5,200 mAh) and Samsung Galaxy S25 Ultra (5,000 mAh). Powering an environment friendly, cutting-edge Qualcomm Snapdragon Elite Gen 5 chip and an FHD+ show, that greater battery makes the OnePlus 15 the longest-lasting smartphone I’ve examined in my 15 years of expertise.

I had zero hassle getting by means of two full days of my traditional, pretty intensive cellphone utilization with out plugging it in. I normally wind up spending a number of hours on my cellphone each day — it’s a part of the job, y’know? — I’m usually bouncing between looking the net, scrolling by means of my social media accounts on Instagram, Threads, and Reddit, protecting tabs on e-mail, all whereas sending messages to pals and colleagues and streaming music. (For testing functions, I additionally made positive to squeeze in about an hour a day of gaming and watching YouTube movies.)

Most Android telephones would at the very least want a top-off from a charger to get by means of a day like that. The big-screen Pixel Pro and the Galaxy S25 Ultra can final two days, however provided that you don’t use them as a lot. When I toned down my utilization, I discovered the OnePlus 15 might truly final three full days with out charging. That’s fully remarkable amongst fashionable telephones.

If all this discuss in regards to the dimension of the battery was worrying you in regards to the cellphone’s heft, don’t fret. The OnePlus 15 truly weighs lower than the Google Pixel 10 Pro and the Samsung Galaxy S25 Ultra — 211 grams, versus 232 grams for the ten Pro and 218 grams for the S25 Ultra. The secret, it appears, is that the OnePlus battery makes use of superior silicon nanostack expertise, which boosts its capability whereas taking over much less area than a typical battery.

Peerless Charging Speeds

Equally essential to the OnePlus 15’s battery-life victory lap, this cellphone prices rapidly. With a most 50-Watt (W) charging enter, it smokes the competitors in each wired and wi-fi charging pace. Using the bundled charging adapter — one thing most cellphone manufacturers make you purchase individually as of late — you’ll be able to absolutely cost it from 0 to 100% in about 45 minutes.

And the quantity of battery life you get from a fast top-off is simply as spectacular. I used to be capable of get 15 p.c, from 25 to 40, within the 5 minutes it took me to organize and drink my afternoon espresso. You can truly watch the battery meter refill in actual time because it prices. I discovered it thrilling, to be sincere.

OnePlus additionally sells a big 50W wireless fast charger, which may cost the cellphone sooner than different flagships do with wired charging. 50W charging is uncommon amongst smartphones proper now: The Pixel 10 Pro and the Galaxy S25 Ultra assist a most charging enter of 30W and 45W, respectively. Those identical telephones cost wirelessly at simply 25W — half of what you get with the OnePlus 15.

It’s More Than a Big Battery, Though

As with earlier OnePlus telephones, the parts beneath the hood listed below are according to different flagship Android telephones — there’s a cause I’ve been mentioning the S25 Ultra and Pixel 10 Pro a lot: They are the simplest factors of comparability.

As anticipated, the OnePlus 15 packs Qualcomm’s newest Snapdragon 8 Elite Gen 5 chip, with 12 or 16 GB of RAM for fast interactions and flawless multitasking, and as much as 512 GB of ultra-fast storage. The cellphone’s AMOLED touchscreen is vivid, sharp, and snappy, delivering easy animation on menus and in video games at as much as 165 frames per second. The digital camera, too, is in the identical ballpark as different prime Android telephones, that includes a lens stack with a trio of high-resolution sensors and a high-resolution selfie snapper on the entrance.

Wrap-Up

The OnePlus 15 rewrites the foundations of smartphone battery efficiency and charging. It isn’t as flashy an improve as Apple’s and Samsung’s ultra-thin iPhone Air and Galaxy S25 Edge. Those telephones look superb, however should be charged incessantly: You’re buying and selling fashion for substance. The OnePlus 15 is a little more modest in its aspirations, but additionally extra sensible. Personally, I’ll take the improve that makes my life simpler and provides me the liberty to look away from the battery meter.
