OnePlus might be working on a phone with unbelievably good battery life

Mobile device batteries are not just improving — they are evolving. As a result, modern smartphones can last at least 24 hours between charges, if not longer. Now, thanks to innovative work happening at OnePlus and Oppo, the companies are reportedly creating a 7,000mAh battery for a future smartphone. If this becomes a reality, it could redefine the design and usage of smartphones going forward

According to leaker Digital Chat Station (first spotted by Android Authority), the large battery could arrive on at least one upcoming smartphone. For context, it was previously reported that the OnePlus 13 would have a 6,000mAh battery.

The phone mentioned in this latest leak is not believed to be the OnePlus 13, but another model. Specifically, it’s rumored that the OnePlus/Oppo phone with this 7,000mAh battery will be a midrange device.

The world has already seen phones with 7,000mAh or similar-sized batteries, including the Samsung Galaxy F62 and Galaxy M51. Others, from niche players, have even included larger batteries. Unfortunately, larger batteries have meant much larger phones; most of today’s bestselling phones are around 5,000mAh.

For example, the Samsung Galaxy S24 Ultra and Apple iPhone 15 Pro Max batteries have around this capacity. The OnePlus 12 has a typical battery capacity of 5400mAh. If OnePlus and Oppo release phones with 7,000mAh batteries, let’s hope they can make them thinner than previous attempts.

Android Authority notes the OnePlus Ace 3 Pro features a prominently advertised silicon-based 5,500mAh battery. This type of battery offers higher density than competing options, allowing for greater capacity with a smaller footprint. It’s reasonable to assume that the company’s 7,000mAh battery could use similar technology without resulting in increased thickness or weight.

Is the OnePlus 13R’s camera worth an extra $100? I found out
White OnePlus 13R held in hand over blue OnePlus 12R.

In 2024, OnePlus made a breakthrough with the 12R. Despite having followed the trend of launching R-series phones for several generations prior without any significant impact, OnePlus finally appeared to find the perfect feature blend that qualifies as an excellent value for money and recreated the same effected early generations of OnePlus phones had.

The OnePlus 12R was rightly dubbed spectacular in our review last year, and the OnePlus 13R is a step in the same direction, except it improves -- at least, on paper -- in areas where the former couldn't impress us. The camera is one of those aspects, and OnePlus touts the 13R to be significantly better. Our review of the OnePlus 13R also leans towards a similar conclusion, calling the 13R's cameras "genuinely solid."

OnePlus 13 lands useful AI tricks and a fix for camera snags

Merely days after releasing a major software update for its latest flagship, OnePlus has begun the rollout of another incremental patch for its new flagship phone. The OxygenOS 15.0.0.405 build, which is now headed to OnePlus 13 users in all major markets, brings a bunch of practical AI upgrades, among other feature tweaks.

The focus of these AI upgrades is mostly on refining the translation experience. For example, the phone will show the live-translated speech in real time on the screen. Taking a leaf out of Samsung’s Galaxy AI book, the latest update also brings a “face-to-face translation feature.”

The OnePlus 13 has ruined Android phones for me
A person holding the OnePlus 13.

The Samsung Galaxy S25 Ultra is going to be my primary smartphone for at least the next few weeks, and I’m coming to it from the OnePlus 13. I first put my SIM card in the OnePlus 13 three months ago, and no one has been able to wrestle it from my hands since. For me, this is an astonishingly long time to use an Android phone, and it speaks volumes about what a superb phone it is.

I'll be using the Galaxy S25 Ultra for the next few weeks, but I'm going to miss the OnePlus 13. Here's why.
Why so long?
