00:00Hey guys we've got the OnePlus 15 here. I thought about doing an episode of Buyer's Skip but you
00:04guys have been loving these Tom's Guide battery test videos and the OnePlus 15 battery life
00:09absolutely deserves its own video so let's get into it. So over the years OnePlus has put in a
00:16lot of work around smartphone batteries and with the kind of features this phone has the OnePlus
00:2115 is basically one big battery life flex. The OnePlus 15 packs a record setting 7300 milliamp
00:28our silicon nanostack battery. Yeah that's ridiculous maybe even overkill but what makes
00:33this cooler isn't just the battery size it's the tech inside. That nanostack technology features an
00:39industry-high 15% silicone in the anode. Translation more energy in the same space so you get insane
00:45endurance without making your phone a brick. And get this the battery isn't just big it's built to
00:50stay healthy long term. After four years of use OnePlus says it should still hold over 80% of its
00:55original capacity. We talked a lot about this in our iPhone battery life tips video. That 80% gauge is
01:01actually pretty important when it comes to battery health and speaking from observations a lot of
01:06iPhone users get there in two and a half to three years. Extreme weather is a secret battery life killer
01:11but for the OnePlus 15 it apparently should be no problem. This battery can handle the cold. We're
01:16talking negative 20 degrees Celsius or negative 4 degrees Fahrenheit. That all sounds great but we have to
01:22put all of OnePlus claims and features to the test. For this new to the channel at Tom's Guide we
01:27run a
01:27standardized battery test across every phone. We call it the Tom's Guide battery test. The screen is
01:33locked to 150 nits. The phone's on 5G and it just keeps surfing the web until it dies. That way
01:38the results
01:39are consistent and easy to compare. So much so that we even keep a running list of the best phones
01:44for
01:44battery life which I'll link below. Speaking of lists, the OnePlus 15 makes it but where does it fall in
01:50the
01:50rankings? Can I get a drumroll please? Last thing in an absolutely insane 25 hours and 13 minutes, the
01:57OnePlus 15 is officially crowned the best phone for battery life overall. Not only that, I'm like 99% sure
02:03this is the best smartphone we've ever tested for battery life. I honestly haven't even wrapped my head
02:08around it yet. And it's not just the fixed test that the OnePlus 15 battery life wowed. In addition to
02:14running
02:14it on the bench, I've also been using this for a minute now and I'm averaging two days and 11
02:19hours of use
02:19on a full charge. So like two and a half days. Incredible. Now let's compare the OnePlus 15 battery life
02:27to
02:27some other flagship smartphones starting with the iPhone 17 Pro Max. Another one that ranked very highly on our battery
02:34life list. The iPhone 17 Pro Max lasted 17 hours and 54 minutes in the same test. So basically 18
02:40hours,
02:41that's over a six hour difference from the OnePlus 15. Even with how much Apple also prioritized battery life
02:47in this year's iPhone family. Then there's the Galaxy S25 Ultra, another flagship Android competitor.
02:54That phone lasts 14 hours and 27 minutes or about 14 and a half hours. That means the OnePlus 15
03:00lasts over
03:0010 hours more than the Galaxy S25 Ultra. Do with that information what you will. Maybe factor in that
03:06the OnePlus 15 starts at $900 versus $1,300 for the S25 Ultra. We usually don't go too in-depth
03:14with
03:14charging in these videos. But with this phone in particular, there are some special features worth
03:19calling out. The OnePlus 15 supports 50 watt AirVOOC wireless charging and 80 watt SuperVOOC wire charging.
03:25Meaning it can charge up to 100 watts with an optional OnePlus power adapter that I'll link in the description
03:31in case you want to pick one up. So with the adapter, it goes from dead to over 80%
03:36in just 30 minutes.
03:37Then there's bypass charging. This one's interesting. This feature powers the device directly from the outlet
03:43while gaming, bypassing the battery to significantly minimize heat generation and preserve long-term battery
03:49health during marathon sessions.
03:52So that's pretty much everything you need to know about the OnePlus 15 battery life.
03:56This thing's like a monster. And like I said at the top of this video, I could do a full
04:00review,
04:00but the battery life is the thing that we'd hype up the most anyway. Let me know if the results
04:05surprised
04:05you and how much you actually consider battery life when making your next smartphone purchase.
