OnePlus continues to announce interesting news this week. Earlier today, the company announced the OnePlus Nord CE4 Lite. This is a budget but fully featured phone that will debut later this summer.

Not to leave high-end consumers behind, OnePlus also announced the Ace 3 Pro, a high-end smartphone series generally only available in China. What makes the upcoming phone interesting, however, is its new "glacier battery." [In general, cell phone batteries haven't changed much in the last few years. Indeed, most flagship phones like the Samsung Galaxy S24 Ultra and the Google Pixel 8 Pro have 5,000 mAh batteries, with even larger ones expected in the future.

OnePlus promises to change this with its new Glacier Battery, which, as Android Authority discovered on Weibo, is said to pack 6,100 mAh battery cells into the space occupied by a 5,000 mAh cell.

While most batteries are composed of lithium-ion, OnePlus has built this new Glacier with "silicon carbon anode" technology, co-developed by OnePlus and Chinese battery maker CATL, which is said to provide two days of use on a single charge. It is said to be able to last two days on a single charge.

OnePlus says the battery is capable of a 100W fast charge and can go from 1% to 100% in just over 36 minutes. The company claims the battery will retain at least 80% of its original capacity even after four years of use.

For reference, the battery is said to run for up to 2 hours of gaming or 3.5 hours of watching videos like TikTok.

According to a Weibo post, Glacier Battery's "high-capacity bionic silicon carbon material" allowed OnePlus to develop a smaller battery than the graphite batteries that make up the standard 5000mAh battery.

The handset maker is no stranger to putting high-capacity batteries in its phones; OnePlus phones like the OnePlus 12 and OnePlus 12R come with 5,400 mAh and 5,500 mAh batteries. The just announced Nord CE4 Lite will have 5,110 mAh, at least in Europe, and probably 5,110 mAh in the US due to battery density regulations. In the rest of the world, it has a 5,500 mAh battery.

Next year's chipsets like Qualcomm's Snapdragon 3 Gen 4 are expected to be battery-eating monsters, so if OnePlus' new batteries ship from China and end up in other OnePlus phones, or even competitors' devices would be of some use.
