OnePlus’ gigantic rumored battery exhibits w...

I’ve at all times supported the thought of user-replaceable batteries in smartphones, however I do perceive why it makes some sense to make use of non-replaceable ones past simply the income concerned. A totally built-in one generally permits a telephone to be extra compact, or tackle new and strange type elements. By extension, this will additionally improve energy effectivity, since different elements will be positioned and sized extra optimally.

A first-rate instance of this can be a mysterious, upcoming OnePlus system, rumored to have a large 7,800mAh battery (per Wccftech). That is even bigger than the 6,260mAh one within the

OnePlus 13T
, and it will completely smoke the 5,000 and 4,685mAH batteries within the

Galaxy S25 Ultra
and

iPhone 16 Pro Max
, respectively. Actually, given studies about Apple and Samsung’s upcoming ultra-slim telephones, it feels like it may be as much as corporations like OnePlus to point out the majors methods to do batteries appropriately.

Is the iPhone 15 still worth buying in 2025? The answer is complicated

Presumably, however you should not get one straight from Apple.

What are Apple and Samsung doing flawed, precisely?

Type over perform

I’ve touched on this lately, so I will not go into the complete particulars, however the brief model is that Apple’s rumored

iPhone 17 Air
and Samsung’s teased

Galaxy S25 Edge
are every anticipated to sacrifice battery life to realize most thinness. Certainly, the declare from The Information is that inner Apple testing estimates solely 60 to 70% of individuals will have the ability to get via a full day with out recharging — which is why the corporate can be rumored to be creating a brand new battery pack, regardless of having discontinued the MagSafe Battery Pack in 2023.

The kicker is that each Apple and Samsung are probably utilizing silicon-carbon battery expertise, a current improve of the lithium-ion batteries we see in all the pieces from smartphones to

electric cars
and PEVs (private electrical autos). The key profit is improved vitality density — so that you’d assume that at a minimal, telephone makers would maintain the road on battery life, merely shrinking their telephones a little bit.

As an alternative, Apple and Samsung appear to be prioritizing thinness in any respect prices, for causes that are not completely clear past aesthetics and bragging rights. It has been years since I’ve heard anybody complain about how thick a telephone is, if not a decade or extra. Complaints have trended in the wrong way, I would say — with no case, some telephones will be so skinny and slippery that they are exhausting to grip securely. Even my spouse’s OnePlus 9 5G has that subject. A couple of foldables, like Google’s

Pixel 9 Pro Fold
, are so skinny when open that they really feel like they may bend or snap.

My greatest guess is that the businesses are attempting to offset the elevated manufacturing prices of silicon-carbon, however I do not know that this excuse flies in gentle of the OnePlus rumors. That 7,800mAh battery is explicitly claimed to be a silicon-carbon mannequin, making it exhausting to know why the iPhone 17 Air could not match the 4,685mAh capability of the iPhone 16 Professional Max, by no means thoughts providing worse efficiency than the bottom iPhone 16. Even when the 7,800mAh rumor is fake, the OnePlus 13T’s 6,260mAh battery is a concrete actuality. That telephone launched in April 2025 — one thing coming in Might or later should be in the identical ballpark.

Getting priorities straight

Or, listening to what prospects truly need

My largest subject is that Apple and Samsung appear to be actively ignoring the longest-running public gripe about smartphones: longevity. Whereas some pre-iPhone gadgets may final a number of days on a cost, it is taken as a right now that it’s worthwhile to cost a telephone daily. Typically, twice per day is the sensible actuality.

As an experiment, I lately prevented topping up my iPhone 16 Professional in any respect till bedtime. The outcome was that after roughly 16 hours, my telephone was right down to 17% — regardless of my most intense actions being podcasts, some app updates, a Reuters video briefing, and some rounds of Wordle and Phrases With Mates. Apple claims that the telephone ought to be able to 22 hours of continuous streaming video. That is pure fantasy, but supposedly two hours higher than the iPhone 15 Professional. I won’t have the ability to deal with the iPhone 17 Air below each day situations, not to mention cross-country journeys.

Each smartphone maker ought to prioritize battery life. It has been a very long time since smartphones have been a luxurious for wealthy professionals — many people rely upon them for our jobs, social lives, and navigating round city. There are rural African farmers utilizing smartphones to enhance their crop yields. In excessive eventualities, individuals rely on smartphones for survival, to the purpose that catastrophe reduction businesses generally embody telephone charging of their listing of priorities. Nobody ought to be panicking about their telephone operating low similtaneously they’re making an attempt to flee a hurricane or earthquake.

I am glad, then, that at the least one firm is profiting from silicon-carbon to do what ought to be an apparent factor. Typically revenue margins must take a backseat, if not for charitable causes, then simply to fulfill genuine buyer demand and preserve individuals loyal. Somebody whose telephone is at all times operating on fumes goes to be tempted by different manufacturers.

In that respect, I am inquisitive about how Apple and Samsung’s ultra-slim telephones are going to promote. I doubt they’re going to be outright failures, because the corporations have a whole lot of promoting may, they usually’ve presumably completed some fundamental market analysis. However I additionally doubt that the merchandise might be runaway hits — charging a premium for sub-par battery life is a recipe for weak gross sales until you provide a dramatic profit in change. And as I’ve hopefully established, thinness can truly be a detriment as of late.

I believe the best-case state of affairs is that Apple and Samsung are conscious of this, however hope that sufficient individuals will purchase in to make silicon-carbon batteries cheaper to provide, and thereby de facto for improved capability within the

iPhone 18
and

Galaxy S26
. I’d get my want in spite of everything, if I am fortunate — simply not as well timed as I would like.
