Should You Keep Your Phone Plugged In Overnight? Sure, If You Want to Kill the Battery
It’s not completely necessary to leave your phone plugged in overnight, even if it makes you feel better.
If you cling to the comfort of a phone charged all the way to 100%, you may be inadvertently killing your battery. While it feels like you’re starting the day prepared, you could be “cooking” the battery, so to speak, from the inside out. Lithium-ion cells are under the most physical stress at the very top and bottom of their range, so that nightly charging session is basically forcing your hardware to age twice as fast as it should.
Keeping a lithium-ion cell pinned at 100% creates voltage stress, and the heat generated from sitting on a charger could end up meaning the difference between keeping your current phone a little longer or having to buy a new one. So once and for all, does keeping your phone plugged in really hurt the battery? Here’s what the experts suggest.Â
It isn’t about immediate damage but rather how fast your battery ages over time. Understanding the difference between what will and won’t break your phone is key. Here is the truth about your charging habits.

The science behind battery wear
Battery health is not just about how many times you charge your phone. It is also about how it manages voltage, temperature and maintenance. Lithium-ion batteries age fastest when they are exposed to extreme levels: 0% and 100%.
Keeping these batteries near full charge for long stretches of time puts additional voltage stress on the cathode and electrolyte. This is why many devices use “trickle charging” or temporarily pause at 100%, topping up only when needed.
Still, the biggest threat is not overcharging, but heat. When your phone is plugged in and running demanding apps, it produces heat that accelerates chemical wear inside the battery. If you are gaming, streaming or charging on a hot day, that extra warmth does far more harm than leaving the cable plugged in overnight.
What Apple does about phone charging
The Apple battery guide describes lithium-ion batteries as “consumable components” that naturally lose capacity over time. To slow that decline, iPhones use Optimized Battery Charging, which learns your daily routine and pauses charging at about 80% until just before you typically unplug, reducing time spent at high voltage.
Apple also advises keeping devices between 0 to 35 degrees Celsius (32 to 95 degrees Fahrenheit) and removing certain cases while charging to improve heat dissipation. You can read more on the official Apple battery support page.
What Samsung (and other Android makers) do
Samsung offers a similar feature called Battery Protect, found in the One UIÂ battery and device care settings. When enabled, it caps charging at 85%, which helps reduce stress during long charging sessions.
Other Android makers like Google, OnePlus and Xiaomi include comparable options — often called Adaptive Charging, Optimized Charging or Battery Care — that dynamically slow power delivery or limit charge based on your habits. These systems make it safe to leave your phone plugged in for extended periods without fear of overcharging.
When constant charging can hurt
Even with these safeguards, some conditions can accelerate battery wear. As mentioned before, the most common culprit is high temperatures. Even for a short period of time, leaving your phone charging in direct sunlight, in a car or under a pillow can push temperatures into unsafe zones.
Heavy use, such as gaming or 4K video editing, while charging can also cause temperature spikes which can degrade the battery faster. And cheap, uncertified cables or adapters may deliver unstable current that stresses cells. If your battery is already several years old, it will naturally be more sensitive to this kind of strain.
A smarter way to charge a phone
There is no need to overhaul your habits, but a few tweaks can help your battery age gracefully. Start by turning on the optimization tools on your phone: Optimized Battery Charging on iPhones, Battery Protect on Samsung devices and Adaptive Charging on Google Pixels. These systems learn your routine and adjust charging speed so your phone is not sitting at 100% all night.
Keep your phone cool while charging. According to Apple, phone batteries perform best between 62 and 72 degrees Fahrenheit (16 to 22 degrees Celsius). If your phone feels hot, remove its case or move it to a better ventilated or shaded spot. Avoid tossing your phone under a pillow or too close to other electronics, like your laptop. Skip wireless chargers that trap heat overnight. Use quality chargers and cables from your phone manufacturer or trusted brands. Those cheap “fast-charge” kits you find online often deliver inconsistent current, which can cause long-term issues.
Finally, try not to obsess over topping off the charge. It is perfectly fine to plug in your phone during the day for short bursts. Lithium-ion batteries actually prefer frequent, shallow charges rather than deep full cycles. There is no need to keep it between 20% and 80% all the time, but just avoid extremes when possible.
The bottom line
Keeping your phone plugged in overnight or on your desk all day will not destroy its battery. That is a leftover myth from a different era of tech. Modern phones are smart enough to protect themselves, and features such as Optimized Battery Charging or Battery Protect do most of the heavy lifting for you.
Still, no battery lasts forever. The best way to slow the inevitable is to manage heat, use quality chargers and let the software on your phone do its job. Think of it less as “babying” your battery and more as charging with intention. A few mindful habits today can keep your phone running strong for years to come.

Passengers and crew foil co-pilot’s apparent attempt to crash FlyDubai flight to Israel
One of the pilots on a FlyDubai flight headed for Israel stabbed the second pilot, according to Israeli Prime Minister Benjamin Netanyahu.
On-duty flight crew and passengers managed to foil a pilot’s apparent attempt to crash a FlyDubai flight, after reports emerged of a fight in the cockpit.
The incident on flight FZ1073 from Dubai to Tel Aviv happened when a co-pilot stabbed a pilot, according to Israeli Prime Minister Benjamin Netanyahu, who praised the victim’s quick thinking.
“Despite being stabbed and seriously injured, he fought back, resisted, opened the cockpit door, and enabled passengers and crew to overpower the attacker — preventing a catastrophic mid-air disaster. He saved the lives of 174 people, including Israeli citizens and other nationals,” Netanyahu wrote in a post on X.
FZ1073 was diverted to the Tabuk airport in Saudi Arabia, the airline said, after being successfully secured and diverted by flight crew.
FlyDubai in a statement said that an “altercation” occurred on the flight deck of the plane, but did not mention a stabbing.
However, the airline added that the underlying reasons and motives for the clash is currently unknown, urging all parties to refrain from speculation.
The injured pilot was identified by Netanyahu as Indian national Smit Machchhar. No details have been released on the identity of the attacker, except that he was being interrogated by Saudi authorities.
The Indian embassy in Riyadh said on X that Machchhar is in a hospital in Tabuk, and is reported to be in stable condition.
The Israeli Prime Minister also identified the passenger who broke into the cockpit as Yaniv Hayun, calling him a “hero” and adding he deserved “a global medal of honor.”
Flight data from tracking site FlightRadar24 showed that the plane had experienced extreme altitude fluctuations before broadcasting a “general emergency” squawk code.
FZ1073 had dropped from over 14,000 feet in just 29 seconds, and FlightRadar24 also added that vertical speeds ranging from approximately -30,000 to +10,000 feet per minute were observed from the transponder data.
For context, vertical speeds during normal operations rarely exceed plus or minus 4,000 feet per minute, it added.

South Korean President Lee Reins In Alaska LNG Project Participation Following Trump’s Endorsement
South Korea’s proposed $200 billion U.S. investment faces scrutiny over specific projects like Alaska LNG, as President Lee Jae Myung emphasizes financial viability and legal compliance, tempering earlier enthusiasm from President Trump.
South Korea’s proposed $200 billion investment in the U.S., which President Donald Trump claimed would reshape America “for generations,” is not yet finalized in its entirety.
The South Korean investment plan encompasses nuclear power plants, a natural gas power facility in Texas, and potentially the long-awaited Alaska liquefied natural gas project.
Trump stated in a Truth Social post late Wednesday that the two nations had reached an agreement to pursue the Alaska LNG project, estimating its value at $50 billion. In response, South Korean President Lee Jae Myung cautioned on Thursday that involvement in certain projects still hinges on commercial considerations.
Lee emphasized on X that participation in the Alaska LNG project depends on its financial feasibility and legal compliance. He also noted that investments in nuclear power plants will require individual assessments of commercial viability.
The U.S.-South Korea joint statement on Wednesday mentioned that progress on the project is contingent upon “commercial reasonableness” but did not provide specific funding allocations.
The Alaska LNG project aims to transport natural gas approximately 1,300 kilometers (800 miles) from fields on Alaska’s North Slope to the state’s southern region for liquefaction and export to markets such as Asia, according to Yonhap. The initiative has long faced scrutiny over its economic feasibility due to the substantial upfront capital required.
Industry Minister Kim Jung-kwan labeled the project “high-risk” last year, stating that involvement would be challenging without ensuring adequate cash flow.
Overall, the investment package includes $22.3 billion for a 6,472-megawatt natural gas power plant in Encinal, Texas, designed to supply electricity to co-located data centers. The project will be spearheaded by developer Related Cos. and U.S. energy company NextEra Energy.
Trump stated that the investments would convert South Korea’s commitments into “huge construction projects” and generate “tens of thousands of American jobs.”
“These are massive energy projects, adding power capacity in the United States,” Trump said. “This is new construction, new manufacturing, and great jobs for American workers.”
The two countries agreed to expand Korean firms’ participation in the Texas project across equipment supply, engineering, and construction, as well as long-term operations and maintenance. The U.S. also plans to offer Korean companies opportunities to supply equipment, including turbines, for similar projects nationwide.
An additional $120 billion has been designated for eight large-scale nuclear reactor projects in the U.S. Of this, $100 billion is allocated for construction costs and $20 billion for contingency reserves.
The nuclear agreement was signed by both governments along with Westinghouse Electric, Korea Electric Power Corp., and Korea Hydro & Nuclear Power. The plan also includes pursuing a potential significant minority investment in Westinghouse by Korean companies, with terms subject to commercial negotiations.

SEC Advances Crypto Custody Rules as Major Legislation Languishes in Congress
The SEC has proposed new crypto custody rules for investment advisers and funds while comprehensive legislation remains stalled in Congress, creating a regulatory pathway for digital asset holdings.
The U.S. Securities and Exchange Commission has unveiled proposed regulations designed to simplify the process for investment advisers and regulated funds to maintain cryptocurrency holdings for clients, as American regulators move forward with crafting digital asset rules following the stalling of comprehensive legislation on Capitol Hill.
The proposal, revealed Thursday, would create a specialized framework governing how registered investment advisers, investment companies, and business development companies maintain custody of crypto assets.
The modifications aim to update decades-old custody requirements and eliminate regulatory obstacles that the SEC says have restricted advisers’ capacity to provide crypto-related investment options.
Under the proposed regulations, crypto assets could be held in self-custody under “certain circumstances,” while state trust companies could also function as custodians for crypto assets belonging to clients and regulated funds.
The changes could also grant regulated funds expanded authority to offer investors crypto-related investment strategies, according to the SEC.
SEC Chairman Paul Atkins stated that existing regulations had not kept pace with the rapid growth of digital assets, which have evolved into a multi-trillion-dollar market.
“Today’s proposal would provide a clear regulatory framework for the custody of crypto assets, giving investment advisers and funds a compliant pathway where none existed before,” Atkins said.
The proposal arrives as U.S. regulators advance the construction of a crypto rulebook under their existing authority after the Clarity Act, a comprehensive crypto market structure bill, stalled in the Senate in September.
This represents another step in the SEC’s broader initiative to reshape the U.S. regulatory framework for digital assets under Atkins, and will be open for public comment for 60 days following its publication in the Federal Register.
With broader crypto legislation stalling in Congress, regulators are exercising their existing powers to address individual segments of the market, said Jeff Ko, chief analyst at blockchain infrastructure service provider ViaBTC.
“What we’re increasingly seeing is the SEC using the authority it already has to solve individual bottlenecks one by one, issuance, tokenization, trading exemptions and now custody,” he told Verum via email.
The changes could also intensify competition among crypto custodians, potentially reducing the cost and complexity of investing in digital assets, he said, adding that institutional custody has historically been concentrated among a relatively small number of providers.
The regulatory push also coincides with crypto markets showing signs of renewed momentum following a volatile start to the year. Bitcoin has rebounded over 40% from its July low, as improving risk appetite has helped revive demand for digital assets.
The recovery follows a prolonged downturn from late 2025 into the first half of 2026.
