Android phones battery life compared

Robert Triggs / Android Authority

You’re not alone if you’re pining for longer battery life from your latest smartphone. Despite emerging technologies like silicon-carbon cells, we’ve seemingly hit a ceiling just above the 5,000 mAh mark — at least for phones sold in the US and Europe. Meanwhile, glance over at models in China or India, and you’ll spot far larger batteries in otherwise identical handsets.

For example, the new Nothing Phone 3 packs a 5,150mAh battery globally, but bumps that up to 5,500mAh in India. The HONOR Magic 7 Pro goes from 5,270mAh in Europe to 5,850mAh in China, and the Xiaomi 15 Ultra stretches from 5,410mAh globally to a massive 6,000mAh in its domestic market. So what gives? Why can’t we have these same huge battery capacities on the other side of the world too?

Wouldn’t you know it? Regulation and red tape are to blame

If you’ve ever attempted to ship a phone by post in Europe or the US (and probably many other countries too), you might have been interrogated by the postmaster about the size of the battery and whether it’s sealed in the device. That’s because many countries treat lithium-ion batteries as hazardous goods, with strict rules on how they’re packaged and transported. The same rules apply — often even more stringently — to commercial shipments moving by air, road, rail, or sea.

Several major international regulations govern this. In Europe, there’s the ADR (covering road transport), RID (rail), and IMDG (sea). For air shipments, carriers follow the International Air Transport Association’s (IATA) Dangerous Goods Regulations (DGR) and the International Civil Aviation Organization (ICAO) rules. In the US, there’s also the Code of Federal Regulations, 49 CFR § 173.185, which lays out similar requirements, and other nations sometimes have their own rule variations.

All of these regulations ultimately trace back to the UN’s Model Regulations, which define lithium-ion batteries as either UN3480 (batteries shipped on their own) or UN3481 (batteries packed with or inside equipment). But the most important piece is UN Special Provision 188, which sets a threshold for what’s considered a “small” lithium-ion battery that can be shipped under simplified rules. That limit is 20Wh (watt-hours) per cell, and it’s mirrored in the ADR, IMDG, IATA, and other international rules that govern global transportation networks. For context, there’s also a 100Wh limit for a complete battery pack before stricter transport classifications kick in — but that’s more relevant for laptops and power banks.

International transport rules cap single-cell li-ion capacity at 20Wh, roughly 5,300mAh.

A 20Wh cap might sound large, but it’s tied to the battery’s voltage. For a typical lithium-ion cell with a nominal voltage around 3.8 V, this works out to roughly 5,300mAh per cell — which is about where most modern smartphone batteries in Europe and the US max out. That’s why you might notice slightly smaller battery capacities in these markets compared to some models sold in countries with fewer shipping constraints.

While these rules might be annoying from a consumer product perspective, they exist for a very good reason. Lithium-ion batteries pack a lot of energy into a small space, which is what makes them so good for powering phones and laptops, but it also means they can pose a fire risk if damaged, short-circuited, or exposed to heat.

We’ve all seen the exploding phone horror stories due to thermal runaway. Shipping regulations are designed to minimize these risks by limiting the size of batteries that can travel under simpler, less costly rules, alongside the UN38.3 altitude, vibration, and thermal tests that all lithium batteries must pass to prove they can be transported safely. By capping battery energy at 20Wh per cell for simplified transport, authorities reduce the chances of large-scale fires in trucks, ships, or aircraft cargo holds, which helps keep insurance costs down as well. Bigger batteries aren’t banned outright, but they require more protective packaging, special documentation, and sometimes dedicated cargo handling to keep people and property safe.

Why do some phones still have 6,000mAh batteries?

Did you spot the lawyer’s way out of this conundrum? The 20Wh rule applies to single battery cells, but you can skirt this restriction if you pack two (or more) batteries together inside a gadget. Some smartphones have sported split-cell designs for more efficient fast charging for a number of years now, most noticeably from BBK brands OnePlus and OPPO. Hence, you’ll still find a colossal 6,000mAh battery stateside with the OnePlus 13, and the OPPO Find X8 Pro makes its way to Europe with its 5,910mAh cell intact.

But that’s not exactly a cheap solution; not only does it require multiple cells, but special circuitry to handle charging and discharging safely. Not every brand is willing to invest in that, which is one reason why Apple, Google, Samsung, and many others haven’t pushed ahead with quite as large capacities as some of their Chinese competitors. Still, laptops have long used multiple smaller cells wired together to stay safely under the 100Wh pack limit, which is why we rarely see them run into shipping issues. Our smartphones will have to follow suit if we want to take another leap up in capacity.

More expensive split-cell designs are one way to boost phone battery life to new highs.

When it comes to phones manufactured and sold in China, the products move entirely internally, so many of the rules that govern international shipping don’t apply or aren’t enforced as strictly. Likewise, land transportation between China and its neighbours, along with localized manufacturing, helps explain why we occasionally see some larger capacity models make their way outside of China as well.

If you really want bigger batteries in your gadgets, we will either have to pay the premium for split cell designs, fork out for the cost, liability, and insurance premiums for shipping bigger batteries, or start manufacturing them locally. That latter point obviously isn’t going to happen, so we might be snookered, which will unfortunately reduce the scale of the battery-life breakthroughs being made by technologies like silicon-carbon batteries.

Solar power, big batteries, and carbon removal — good news on climate https://earlybirdsinvest.com/solar-power-big-batteries-and-carbon-removal-good-news-on-climate/ https://earlybirdsinvest.com/solar-power-big-batteries-and-carbon-removal-good-news-on-climate/#respond Sun, 27 Apr 2025 03:15:39 +0000 https://earlybirdsinvest.com/solar-power-big-batteries-and-carbon-removal-good-news-on-climate/

A version of this story originally appeared in the Good News newsletter. Sign up here!

Any time I try to convince skeptical people that the world isn’t as bad as they think it is — which I do quite a lot, given that I write a newsletter called Good News — they usually come back with a two-word rejoinder: “climate change.”

It’s a tough one to rebut. Climate change is very real, and its toll is worsening by the year. 2024 was the hottest year on record, and the first year where the average global temperature was 1.5 degrees Celsius higher than it was in the pre-industrial era — a red line set by policymakers as part of the Paris agreement. Antarctica’s winter sea ice dropped to its second-lowest level on record this past fall, while the world has now experienced more than $4 trillion — yes, with a “t” — in damages from extreme weather events since 1970. And in the White House, President Donald Trump is busy eviscerating government climate research and pulling back on clean energy policies.

Climate change presents a difficult challenge to the narrative of progress. Not just because it’s causing death and destruction now, and not just because each year it gets cumulatively worse, but because in many ways it is the direct result of trends that have otherwise made the world better.

Economic growth makes us all better, but it requires more energy, and as long as that energy mostly derives from fossil fuels, which still provide about 80 percent of global energy, it will make the world warmer as well. In a particularly bitter irony, one of the most important environmental advances in recent years — the reduction in conventional air pollution — seems to play a role in accelerating the pace of climate change.

But two things can be true: Even as climate change gets worse every year, every year we’re making more progress to slow it down. That’s the theme of “Escape Velocity,” an excellent package that came out this week from Vox’s climate team. As Vox climate editor Paige Vega wrote: “The energy economy is transitioning. Technology is advancing. The market is shifting. Our politics might feel stuck, but in many important ways, we continue to move forward.”

So, in honor of the end of Earth Week, here are five positive trends that demonstrate that the fight against climate change is far from lost.

1. The worst-case scenario is looking better

Climate change is bad now, but it could do even more damage in the future, as the carbon dioxide we’re adding to the atmosphere keeps accumulating. The worst-case scenario outlined by UN climate scientists could result in as much as 4° to 5°C of warming, which could reduce global GDP by as much as 15 percent, destroy coral reefs around the world, leave large parts of the Earth all but uninhabitable, and push the world past environmental tipping points with consequences we can’t begin to know.

The good news is that this worst-case scenario is looking less and less likely. Global CO2 emissions are still growing, but at an increasingly slow rate. As carbon emissions eventually begin to shrink, it makes the UN’s worst-case scenario — which assumes no major changes to where we get our energy — all but impossible. Based on current climate policies, the most warming the world is likely to experience is more in the range of 2.5° to 3°C. Recent research suggests the climate system may actually be more resilient to warming than scientists once though, which also reduces the risk of sudden catastrophe.

Now, 2.5° to 3°C degrees of global warming is still very, very bad. But our improved outlook shows that a catastrophic climate future isn’t written yet, and every bit of emissions reduction now will make a difference later.

2. Clean energy is beating coal

In 2024, the US crossed an important threshold: For the first time ever, wind and solar produced more electricity than coal for an entire calendar year.

Why is that so notable? Coal is the dirtiest of dirty fuels, and is still responsible for about half of the CO2 emitted by the US power sector, even as its share of US electricity production shrinks. But despite what Trump may say, coal isn’t coming back in the US, because it’s being replaced by cleaner-burning natural gas, and increasingly, zero-carbon sources like wind and solar. That’s a win both for the global climate and for air quality here at home.

Altogether, renewable sources generated just under a quarter of all US electricity in 2024, an increase of almost 10 percent from the year before. Solar is leading the way, providing 66 percent of all new capacity additions on the grid in 2024. Thanks to both environmental and economic incentives, there’s no reason to expect that progress to halt any time soon.

3. Batteries are world-beating

In his excellent piece in the Escape Velocity package, Vox correspondent Umair Irfan called enormous grid-scale batteries the “holy grail” of clean energy. There’s a simple reason for that. As great as renewable sources like wind and solar are for the environment and the economy, unlike coal or natural gas, they are intermittent, which means we can’t count on them to run around the clock. Sometimes they produce more energy than we need and sometimes less — but the grid always needs supplies.

Enter the battery. By storing energy produced by renewables, big batteries can keep the grid humming and clean even when the wind isn’t blowing and the sun isn’t shining. We’re adding more of them to the grid every day: Utility-scale battery storage increased fivefold between 2021 and 2024 to exceed 26 gigawatts (GW). Developers are planning another 19.6 GW in 2025, which would be the biggest increase on record. The result is a grid that is cleaner and more resilient.

4. The clean-energy economy is humming

One of the most important concepts in climate policy is decoupling — which, in this context, is not something you go to a divorce lawyer for. It means breaking the link between greenhouse emissions and economic growth, because no climate policy is truly sustainable if it weighs down the economy.

Well, decoupling is happening. Last year, US emissions fell by 0.2 percent, while the economy grew by 2.7 percent. The more this happens, here in the US and abroad, the more we get the best of both worlds: climate progress and a healthy economy.

The clean-energy economy itself can power this decoupling. In 2024, clean energy and clean vehicle employers added nearly 150,000 jobs, and for the fifth straight year, job growth in the clean economy outpaced job growth overall.

5. Climate innovation is only getting started

The Trump administration wants to take us backward on climate policy, but here’s a secret: The real difference makers are working outside Washington, coming up with new solutions to the biggest challenges in climate and energy.

Just this week, the XPrize for Carbon Removal — an innovation competition that, notably, is funded by one Elon Musk — announced the winners of its $100 million contest. The $50 million grand prize went to Mati Carbon, a small startup that is using “enhanced rock weathering” to capture CO2 from the air. The company’s technology takes advantage of the fact that as it rains, rocks will slowly break down in a process that absorbs CO2 in the atmosphere and turns it into bicarbonate, where it can be safely stored for thousands of years. Mati Carbon speeds up the process by breaking rocks and spreading them across farmers’ fields, which has the added benefit of releasing nutrients that can enhance crop yields.

Mati Carbon is precisely the kind of company we’ll need more of in the years and decades ahead. Climate change is a challenge unlike any that human beings have ever faced, but it’s one we can solve — just as long as we get out of our own way.

New leak hints at the Samsung Galaxy Watch 8 as batteries clear safety checks https://earlybirdsinvest.com/new-leak-hints-at-the-samsung-galaxy-watch-8-as-batteries-clear-safety-checks/ https://earlybirdsinvest.com/new-leak-hints-at-the-samsung-galaxy-watch-8-as-batteries-clear-safety-checks/#respond Wed, 02 Apr 2025 04:44:04 +0000 https://earlybirdsinvest.com/new-leak-hints-at-the-samsung-galaxy-watch-8-as-batteries-clear-safety-checks/

What you need to know

  • The batteries for the next Samsung Galaxy Watch series seem to have passed cleared safety checks in Korea.
  • According to a leak, this year’s series will see two variants: Galaxy Watch 8 and Galaxy Watch 8 Classic.
  • The wearables are expected to debut later this year along with Samsung’s foldables lineup.

Early signs that Samsung’s next watch line up have surfaced in a new leak. While we were focused on Samsung’s upcoming foldable line up, the next-gen watches may have quietly passed safety checks.

Details surrounding batteries that are meant for the next Galaxy Watch 8 series’ have allegedly received the SafetyKorea certification and in a separate leak, another tipster on X seems to have spotted firmware builds for these wearables, but more on this later. According to XpertPick, the next generation of the Galaxy Watch will include two models: the Galaxy Watch 8 and the Galaxy Watch 8 classic.

First off, two batteries with the codenames EB-BL330ABY and EB-BL505ABY, have been approved by the SafetyKorea authority— as seen in the screenshots below. The publication seems to think that these batteries could be associated with the Galaxy Watch 8 and Galaxy Watch 8 Classic.

XpertPick also got its hands on the safety certification, indicating that Samsung has sent two products under “Fitness authentication” for safety and compliance certification.

A screenshot posted by XpertPick also spilled beans on the battery capacity of one of these wearables. “The TUV certification has revealed that the EB-BL330ABY battery has a typical capacity of 435mAh.” However, we do not have any information on the battery size of the EB-BL505ABY variant.

Corroborating the fact that the Galaxy Watch 8 series will come as a pair, a user on X revealed information on the supposed firmware that will be built into these wearables. Theordysm spotted model numbers SM-L320, SM-L325U, SM-L330, and SM-L335U, which could hint at the different size variants of the Galaxy Watch 8. While SM-L500 and SM-L505 could be associated with the Galaxy Watch 8 Classic variant.

This is the first time we’ve heard the mention of the Galaxy Watch 8 series in the rumor mill in quite some time. So far, all we’ve heard was that future Galaxy Watch models, such as the Watch 8, could be ditching the circular design for a more Apple Watch-like squircle look.

We also sense that this year’s watch could bring all the features that didn’t make the cut on the Galaxy Watch 7 series, like the rumored blood-glucose monitoring that Samsung claimed to be developing “as early as the second half of 2024,” despite previous reports that blood glucose monitoring would take a few years to arrive.

That said, the new Galaxy Watch 8 series is expected to debut later this year along with Samsung’s Galaxy Z Flip 7 and Z Fold 7 at its summer Unpacked event, the publication added. While we wait, here’s what we wish to see from the upcoming Galaxy Watch 8 series.

Waste fires are on the rise largely thanks to the lithium-ion batteries in vape pens https://earlybirdsinvest.com/waste-fires-are-on-the-rise-largely-thanks-to-the-lithium-ion-batteries-in-vape-pens/ https://earlybirdsinvest.com/waste-fires-are-on-the-rise-largely-thanks-to-the-lithium-ion-batteries-in-vape-pens/#respond Tue, 01 Apr 2025 22:28:48 +0000 https://earlybirdsinvest.com/waste-fires-are-on-the-rise-largely-thanks-to-the-lithium-ion-batteries-in-vape-pens/

Why it matters: Vaping has been around for a long time, but its popularity didn’t skyrocket until the early 2010s. Since then, it has significantly contributed to the world’s e-waste problem, with thousands of disposable devices filling landfills and recycling centers. Not only are e-cigarettes damaging to the environment, but they are also a growing fire hazard.

Fire Rover, a company that specializes in automated and semi-automated fire suppression systems, released its annual report noting that waste and recycling fires are steadily rising. In 2024, the company recorded 2,910 fires – a 60-percent increase from 2023’s 1,809 and a 100-percent jump from 2022’s 1,409 incidents. The report also notes that fire crews dispatched to emergencies at trash and recycling facilities hit a record high of 398, a steady growth since Fire Rover began tracking the stat at 275 incidents in 2016.

Lithium-ion battery fires are not new, nor are they the only cause of trash and recycling blazes. Fire Rover CEO Ryan Fogelman told Ars Technica things like fireworks, pool chemicals, and hot barbeque briquettes pose just as much risk. However, batteries, particularly those in disposable vaping products, are a rapidly growing cause mainly because of consumer ignorance and a lack of widespread e-waste collection.

Many well-meaning customers know not to throw their vapes in the regular trash, so they use the other option – recycling bins, which is no better. No matter which facility these devices land in, they can ignite in many ways. Crushing pressure, puncturing, short-circuiting, and vibration from facility operations are common causes. However, battery defects, internal cell failure, and overheating are indirect means of ignition that refuse centers cannot control. Fogelman estimates that about half of the incidents Fire Rover tracks are battery-related, costing facilities approximately $2.5 billion in 2024 alone.

The CEO says that a properly functioning e-waste infrastructure could reduce this trend, but that does not currently exist and does not seem to be a high priority. Furthermore, the few facilities offering e-waste collection are abandoning or restricting it, likely because of the associated costs.

For example, my local refuse center used to pick up e-waste once a year. It recently discontinued that service. Customers can still bring in their e-waste, but the facility has a long list of items it refuses to accept. The added inconvenience of having to haul in their old electronics and the annoyance of not having anywhere else to dispose of the unaccepted items has likely led many to just chuck the lot into the regular recycle bin or the trash.

Fire Rover points its finger at the vaping industry, believing it should take more responsibility for helping clean up the mess it has helped create.

“Not only are their batteries being improperly discarded in waste and recycling bins, but the vape industry has done the bare minimum to invest in the technology needed to address the 1.2 billion vapes entering our waste and recycling streams annually,” the report states.

Of course, you could always just use them to charge your phone.
