If you thought we saw big gains in the best phone battery life this past year, the next 12 months figure to bring us even more long-lasting phones. We''ve just tested our first phone powered by the latest silicon from Qualcomm, and it''s delivered the best result we''ve ever seen on our custom battery test.
Each phone we review goes through the same endurance test, where we have the phones surf the web while we time how long it takes for them to run out of battery. It''s a fairly demanding test where the average phone can pass the 10-hour mark and truly long-lasting devices hold out for even longer.
These days, it takes a time of at least 14 hours to even be considered for a spot on our list. And it''s going to take a very special phone to unseat our new long-lasting champ, the Asus ROG Phone 9 Pro. This gaming-focused phone averaged a time that pushed past the 20.5 hour mark, topping the previous battery life winner by nearly 2 hours.
Even if you won''t want a gaming phone, there are plenty of other options on our best phone battery list, from the latest Apple and Samsung flagships to budget devices from Motorola, OnePlus and Nothing. Even a foldable phone has cracked our top 15 long-lasting phones, and those are devices not really known for lasting a long time on a charge.
The test numbers we use in the above chart reflect the results we got when testing each phone at their default setting for a display''s refresh rate. Often, that means a phone can adjust that rate during our test. We believe that using the default setting is the best way to get comparable results, but since we also test at different refresh rate settings to see what impact that can have on battery life, we''ll note in the write-ups below when phones produced significantly different results after adjusting the refresh rate on their displays.
Asus continues to set the battery life standard with its ROG phones. The latest entry, the ROG Phone 9 Pro pushes things out even further, with the phone posting an average time of 20 hours and 34 minutes on our battery test. That time came with the phone''s display set to an adaptive refresh rate. Locking the screen at its highest refresh rate — 165Hz — did put a hit on battery life, cutting the ROG Phone''s performance by nearly 6 hours. But even that 15-hour, 41-minute time would have put the ROG Phone 9 Pro in 10th place on our best phone battery life list.
Yes, the big battery inside the ROG Phone 9 Pro helps provide multi-day battery life. But the 5,800 mAh power pack has some help from the power-efficient Snapdragon 8 Elite chip running the show. This chipset figures to power a lot of top Android phones coming out in the next year, so the ROG Phone 9 Pro''s battery performance is an exciting preview of what to expect even if you''re not necessarily inclined to get a gaming phone.
The Asus ROG Phone 8 Pro gives up the top spot in our best phone battery life list to its successor, but its 18 hour, 48 minute time remains one of the best we''ve ever seen. And with the ROG Phone 9 Pro not expected to start shipping in the U.S. until 2025, this older gaming device remains the longest-lasting phone you can buy, at least for a little while longer.
While the ROG Phone 9 Pro made a big lead ahead of the ROG Phone 8 Pro''s time, this model improved on its successor by just 16 minutes on our test. Of course, the ROG Phone 8 Pro did that with a smaller battery than its predecessor, making its result look even more impressive.
Like the ROG Phone 9 Pro, you get a 65W charger with the ROG Phone 8 Pro, and charging results were similar — 71% on a drained phone after 30 minutes of charging. By 50 minutes, the phone was completely charged. So you''re never really out of the game with this long-lasting phone from Asus at your side.
The midrange OnePlus 12R is the longest-lasting phone we''ve tested that''s not built specifically for gaming, and it''s also one of three phones in our current rankings to last longer than 18 hours on our battery test. If you need to squeeze even more battery life out of the phone, you can adjust its refresh rate, as that produced a result a few minutes shy of the Asus ROG Phone 8 Pro''s record-setting pace.
The Snapdragon 8 Gen 2 may be an older chipset, especially with Snapdragon 8 Elite phones now emerging, but that''s what allows OnePlus to offer the 12R at such a low price, particularly in the U.S. You can buy a $499 model with 128GB of storage in the U.S., while the OnePlus 12R starts at $599 for 256GB of storage in other parts of the world.
Even with its lower price, the OnePlus 12R doesn''t skimp on OnePlus'' trademark fast-charging. With 80W wired charging speeds in the U.S., we got the phone to a 96% charge after 30 minutes. Don''t expect wireless charging, though.
Additional testing dropped the iPhone 16 Pro Max''s average time from its high of 18:06 to 17:17, but don''t be disappointed by that. This is still the longest-lasting phone Apple has ever offered.
The iPhone 16 Pro Max not only features a larger battery, but the A18 Pro silicon running the show exhibits excellent energy efficiency. The iPhone 16 Pro also runs on an A18 Pro chipset, and it just missed making our list even though it has a much smaller battery than the Pro Max.
Despite reports that 45W charging might be possible the iPhone 16 Pro Max is limited to 30W charging speeds, which helps it get to a respectable if not overwhelming 55% charge after 30 minutes.
The lower-cost OnePlus 12R may be the longer-lasting phone in the OnePlus 12 series, but don''t sell the flagship phone short. The OnePlus 12 still lasted a little more than 17 hours on our battery test with the help of a 5,400 mAh battery and the power management features of the Snapdragon 8 Gen 3 silicon. Curiously, locking the display''s refresh rate at 120Hz adds another half-hour or so to the test result, instead of the default adaptive setting.
