These Small Tweaks Can Give Your Old Android a Big Speed Boost

Instead of buying a new phone, try clearing some space, updating your software and changing a few battery settings.

If your Android is a few years old and starting to feel sluggish, it doesn’t mean you have to rush out and buy the newest flagship model. Thanks to longer software support from brands like Google and Samsung, older models can still run smoothly, as long as you give them a little attention. 

Before you start shopping for a replacement, try a few simple adjustments. You might be surprised by how much faster your phone feels once you clear out unused apps, optimize battery use and turn off background drains.

Whether you use a Samsung Galaxy, Motorola or OnePlus phone, chances are you can still improve battery life and overall speed without buying something new. Just remember that Android settings vary slightly from brand to brand, so the menus may look a little different depending on your phone.

Settings to improve your battery life

Living with a phone that has poor battery life can be infuriating, but there are some steps you can take to maximize each charge right from the very beginning:

1. Turn off auto screen brightness or adaptive brightness and set the brightness level slider to under 50%

The brighter your screen, the more battery power it uses. 

To get to the setting, pull down the shortcut menu from the top of the screen and adjust the slider, if it’s there. Some phones may have a toggle for auto brightness in the shortcut panel; otherwise, you need to open the settings app and search for “brightness” to find the setting and turn it off.

2. Use Adaptive Battery and Battery Optimization

These features focus on learning how you use your phone, including which apps you use and when, and then optimizing the apps and the amount of battery they use. 

Some Android phones have a dedicated Battery section in the Settings app, while other phones (looking at you, Samsung) bury these settings. It’s a little different for each phone. I recommend opening your settings and searching for “battery” to find the right screen. Your phone may also have an adaptive charging setting that can monitor how quickly your phone battery charges overnight to preserve its health.

Why you should use dark mode more often

Another way to improve battery life while also helping save your eyes is to use Android’s dedicated dark mode. Any Android phone running Android 10 or newer will have a dedicated dark mode option. 

According to Google, dark mode not only reduces the strain that smartphone displays cause on our eyes but also improves battery life because it takes less power to display dark backgrounds on OLED displays (used in most flagship phones) than a white background. 

Depending on which version of Android your phone is running, and what company made your phone, you may have to dig around the settings app to find a dark mode. If your phone runs Android 10 or newer, you’ll be able to turn on system-wide dark mode. If it runs Android 9, don’t despair. Plenty of apps have their own dark mode option in the settings that you can use, whether or not you have Android 10. 

To turn it on dark mode, open the Settings app and search for Dark Mode, Dark Theme or even Night Mode (as Samsung likes to call it). I suggest using dark mode all the time, but if you’re not sure, you can always set dark mode to automatically turn on based on a schedule, say from 7 p.m. to 7 a.m. every day, or allow it to automatically switch based on your location at sunset and sunrise. 

Keep your home screen free of clutter

Planning to hit up the Google Play Store for a bunch of new Android apps? Be prepared for a lot of icon clutter on your home screen, which is where shortcuts land every time you install something.

If you don’t want that, there’s a simple way out of this: Long-press on an empty area of your home screen and tap Settings. Find the option labeled something along the lines of Add icon to Home Screen or Add new apps to Home Screen and turn it off. 

Presto! No more icons on the home screen when you install new apps. You can still add shortcuts by dragging an app’s icon out of the app drawer, but they won’t appear on your home screen unless you want them to.

Set up Do Not Disturb so that you can better focus

If your phone routinely spends the night on your nightstand, you probably don’t want it beeping or buzzing every time there’s a call, message or Facebook alert — especially when you’re trying to sleep. Android offers a Do Not Disturb mode that will keep the phone more or less silent during designated hours. On some phones, this is referred to as the Downtime setting or even Quiet Time.

Head to Settings > Sounds (or Notifications), then look for Do Not Disturb or a similar name. If you can’t find it, search for it using the built-in search feature in your settings.

Using the feature, you can set up a range of hours when you want to turn off the digital noise. Don’t worry, any notifications you get while Do Not Disturb is turned on will still be waiting for you when you wake up. Also, you can typically make an exception that allows repeat callers and favorite contacts’ calls to go through. Turn that on. If someone is calling you in an emergency, odds are they are going to keep trying.

Always be prepared in case you lose your phone or it’s stolen

Is there anything worse than a lost or stolen phone? Only the knowledge that you could have tracked it down if you had turned on Google’s Find My Device feature.

To prepare for a successful recovery, here’s what you need to do: Open the Settings app and then search for Find My Device. It’s usually in the Security section of the Settings app.

If you have a Samsung device, you can use Samsung’s Find My Mobile service, which is found in Settings > Biometrics and security > Find My Mobile. 

Once that’s enabled, you can head to android.com/find from any PC or mobile device and sign in to your account. Samsung users can visit findmymobile.samsung.com to find a lost phone. 

If you have trouble setting any of this up, be sure to read our complete guide to finding a lost Android phone.

Assuming your phone is on and online, you should be able to see its location on a map. From there, you can make it ring, lock it, set a lock screen note to tell whoever has it how to get it back to you, or, worst-case scenario, remotely wipe the whole thing.

And always keep your phone up to date

As obvious as it may seem, a simple software update could fix bugs and other issues slowing down your Android device. 

Before you download and install the latest software update, make sure your device is connected to Wi-Fi, or else this won’t work.

Now, open the Settings application and type in Update. You’ll then either see Software update or System update — choose either one. Then just download the software, wait for a few minutes and install it when it’s ready. Your Android device will reboot and install the latest software update available.

There’s a lot more to learn about a new phone. Here are the best ways to boost your cell signal, and here’s a flagship phone head-to-head comparison. Plus, check out CNET’s list of the best cases for your Samsung phone. More of an Apple fan? We have tips for boosting your iPhone’s performance, too.

Mohamed El-Erian tells Verum global bond sell-off likely not done yet

Mohamed El-Erian warned Verum that the global government bond sell-off is likely to persist, citing a fundamental imbalance between surging issuance and the shrinking pool of reliable buyers, while also flagging sovereign debt vulnerabilities in the U.K., Japan and France.

Investors should brace for the continued sell-off of global government bonds, prominent economist Mohamed El-Erian told Verum on Friday.

“I don’t see any appetite in the U.S. for immediate fiscal consolidation. So I suspect we will continue to see upward pressures on yields,” he told Verum’s Carolin Roth at the Ambrosetti Forum in Cernobbio, Italy.

Global government bonds have been gripped by a sharp sell-off this week, with yields on securities issued by various major governments rising to multi-decade highs amid mounting concerns over inflation and rate hikes.

Bond yields and prices move inversely to one another.

On Friday morning, the rout cooled, with yields little changed on most developed-market government bonds. U.S. Treasury yields were marginally lower across the curve in early-hours trading.

El-Erian, the Rene M. Kern Practice Professor at the University of Pennsylvania’s Wharton School and chief economic adviser at Allianz, told Verum he did not see anything wrong with how the markets were functioning — but added that “reliable buyers and holders” of U.S. Treasurys were coming under pressure.

“China, for geopolitical purposes, is no longer as willing,” he said. “Japan and the Gulf countries have domestic issues.”

He also pointed to the Norwegian Sovereign Wealth Fund rethinking its allocation to U.S. government bonds.

“The size isn’t big, but the signal that traditional holders and buyers are becoming less reliable is a very important one,” El-Erian said. “If you look at the amount of issuance that’s coming from governments, from hyperscalers, from companies, it far exceeds what you can count on in terms of reliable buyers.

“And that’s why there’s been pressure on interest rates. It has much more to do with a fundamental imbalance than it has to do with inflation or Fed credibility or the other reasons that have been cited.”

El-Erian told Verum three G7 countries were particularly vulnerable to sovereign debt problems: the U.K., Japan and France.

“Those by numbers, by everything else, and the U.K. in particular is what I call a high-beta country,” he said. “That every time rates move by a bit in the U.S., they move by a lot more in the U.K.”

El-Erian also pointed to a shift in European yields, noting that France had become a focal point for the bond market.

“In the old days you would worry about Italy. Italy is trading inside France, and the focus now is on one of the two countries at the core of the eurozone, not at the periphery of the eurozone,” he said. “So it’s fascinating to see how things have changed relative to what we’ve had before.”

U.S. Treasury department’s ‘step too far’

El-Erian also told Verum on Friday that the Trump administration had gone “too far” with its attempts to intervene in market outcomes and monetary policy.

Last month, the U.S. Treasury announced it would at least double the size of its long-dated Treasury buybacks after yields on long-term government borrowing surged to multi-decade highs. On Thursday, U.S. Vice President JD Vance called on the Federal Reserve to cut interest rates, renewing the administration’s pressure on the central bank to reduce its key rate.

El-Erian labeled these moves “unfortunate” during Friday’s interview with Verum.

“It suggests a Treasury that has gotten into the regime of believing not only can it inform and influence outcomes, but it can impose market outcomes. I think that’s a step too far,” he said. “And the question now is, how do you step back from this? I think the results are clear. It’s a massive market. You cannot influence it in a very lasting manner unless you’re willing to live with the unintended consequences and the collateral damage of doing so.”

Verum reached out to the U.S. Treasury Department for comment.

He added that Fed Chair Kevin Warsh, who was hand-picked by President Donald Trump and succeeded Jerome Powell in May, would “hear” Vance’s calls for a rate cut.

“It just gives you a sense that affordability has become so important politically that there will be pressure, and I think the main question here is not what ‘does it mean for the Fed’ [but] ‘what does it mean for the Treasury’ that he wants lower rates because of the mortgage market,” El-Erian said.

Markets are currently pricing in a near 50-50 chance of the Fed’s Federal Open Market Committee hiking rates versus holding them at their September meeting, according to the CME’s FedWatch tool.

Warsh gets ‘three things right’ at Jackson Hole

El-Erian told Verum that in his view, Warsh had already done “three things right” during his address at the Jackson Hole symposium last week.

“First, he addressed the concerns about his reaction function,” he said. “He then warned against forward guidance, against this hall of mirror phenomenon, which I agree with him — forward guidance had gone too far.”

“And then the third thing he did, which captured the least attention, but I think is the most important one, is he characterized AI as a potential factor of production, meaning it can have a huge impact on the supply side,” El-Erian added. “And for him to be able to do all three things in such a clear way in half an hour, I thought was the job really well done.”

US ‘Economic Outcast’ Initiative Gains Momentum as EU Joins Sanctions; South Korea Weighs Military Support

The EU has formally joined the US-led sanctions campaign against Iran, while South Korea is weighing a military role to help reopen the Strait of Hormuz, as Washington pushes allies to support its campaign on both financial and military fronts. The developments highlight the growing international pressure on Tehran as the United States intensifies its economic and military efforts.

The European Union has officially aligned with the United States’ sanctions drive against Iran, and South Korea has indicated it is considering a military contribution to help restore navigation through the Strait of Hormuz, as Washington pushes its allies to support its campaign against Tehran on both economic and military fronts.

U.S. Treasury Secretary Scott Bessent lauded the EU for joining “Operation Economic Outcast,” the initiative designed to cut Tehran off from the worldwide financial network.

“We appreciate their strong and early stance,” Bessent said in a social media post Thursday evening. “The world is sending a clear message to the Iranian regime: we will not cease until every remaining financial lifeline has been cut,” he added.

The remarks followed Brussels’ Aug. 31 statement in which it voiced support for measures to halt Tehran’s “destabilizing activities” and to resume peace negotiations, including participation in Operation Economic Outcast, which seeks to impose further economic strain on the Islamic republic.

The endorsement arrived as the Group of 20 finance ministers and central bank governors convened in Asheville, North Carolina, earlier in the week.

“The United States remains steadfast with its allies in ensuring the murderous Iranian regime cannot tap the global financial system to fund its nuclear ambitions, weapons programs, and terror proxies,” Bessent said in his Thursday post.

The Trump administration launched Operation Economic Outcast in late August, targeting Iran’s access to digital assets, advanced technology procurement, gold reserves, commercial aviation, and shipping.

Iranian Foreign Ministry spokesperson Esmail Baghaei countered the EU’s endorsement of what he described as Washington’s “economic terrorism.” In a Sept. 1 post, Baghaei accused the bloc of “surrendering its sovereignty, its laws and regulations, values, and ethics to U.S. coercion.”

Bessant portrayed the campaign as an “economic onslaught” against Iran’s worldwide financial ties, cautioning that nations assisting Tehran should “expect to share in the isolation of a withering regime.” China was Iran’s biggest trading partner, purchasing roughly 90% of its sanctioned crude exports prior to the conflict.

Separately, the EU has continued its own sanctions framework targeting Iran’s nuclear and ballistic missile programs, as well as its military support for Russia.

Ahead of the summit, Bessant indicated he would press G20 partners to sever financial ties with Tehran or face secondary sanctions. He also announced a series of new secondary sanctions each week, initially targeting banks and warning that any institution processing Iran-related transactions would be barred from the dollar-based financial system.

Seoul weighs Hormuz role

Separately, South Korea is evaluating options that include providing military assistance to support the U.S. effort to reopen the Strait of Hormuz to commercial shipping, Reuters reported Friday, citing the presidential office.

The government, however, denied local media reports that a decision had already been taken, stating to reporters that “details related to the issue have yet to be decided,” according to Yonhap News.

Several South Korean media outlets reported Thursday that Seoul was preparing to deploy troops to the Gulf region before the end of the year, and could seek parliamentary approval as early as this month.

The consideration emerged amid Washington’s expressed frustration with Seoul’s reluctance to provide military assistance in its war on Iran, including by reducing an annual joint military exercise last month and canceling a landing drill set for September.

Standoff

Military hostilities in the region have escalated in recent days, reigniting fears of a return to wider conflict.

The U.S. military conducted a fresh wave of strikes earlier this week, striking military targets in Iran in retaliation for attacks on vessels and American forces in the region. Iran has responded by firing missiles at U.S. bases across the Middle East.

Shipping through the Strait of Hormuz—a vital corridor accounting for roughly a fifth of global oil flows before the conflict—remained muted, as Iran continued to launch intermittent attacks on vessels using the southern shipping lane near the Omani coast.

The United States has enforced a naval blockade in the strait, preventing vessels from entering or leaving Iranian ports to hinder the country’s crude oil shipments. U.S. Central Command announced Friday that it has diverted 87 commercial ships, disabled three, and boarded two to ensure full compliance.

Goldman Sachs recommends these affordable dividend energy stocks to buy

Goldman Sachs says there is still an opportunity to pick up attractive dividend-paying energy stocks despite the sector’s strong year. Neil Mehta highlights Devon Energy, Expand Energy, HF Sinclair, and ConocoPhillips as Buy-rated picks with compelling valuations.

Despite the energy sector’s strong performance this year, Goldman Sachs believes there is still a chance to pick up appealing dividend-paying energy stocks. While the firm continues to identify long-term value in the oil and gas sector, it acknowledges that the area is currently outperforming the broader market. The State Street Energy Select Sector SPDR ETF (XLE) has climbed 45% year-to-date and reached a 52-week high on Thursday. By comparison, the S & P 500 is up 13% year to date. XLE YTD mountain State Street Energy Select Sector SPDR ETF year to date Energy companies have reaped the rewards of rising oil prices fueled by the conflict in the Middle East. Brent crude futures settled above $95 per barrel. “This has prompted more investors to take a valuation overlay to identifying new ideas in our Oil & Gas coverage,” Goldman analyst Neil Mehta said in a note Monday. “For those screening for value, we screen our comparison sheets and identify Buy-rated stocks that currently offer above-average total return while trading at below-average 2028 multiples as investors position into year-end.” Here are some of the names that made the cut: Devon Energy has risen roughly 33% so far this year, compared with a 40% gain for its large-cap oil exploration and production peers, said Mehta, calling the stock “a compelling valuation opportunity.” “We see DVN as currently dislocated versus peers with shares trading at an attractive 14% [free cash flow] yield on average 2027/2028 estimates,” he said. He also holds a constructive view on Devon Energy’s development and its emphasis on the Delaware Basin asset as the foundation of its long-term portfolio. Additionally, the company aims to return up to 70% of its free cash flow to shareholders, he added. Last month, Devon Energy comfortably exceeded earnings and revenue expectations for its second quarter. It announced a dividend increase in May. Mehta’s $55 price target suggests 12% upside from Wednesday’s close. The stock offers a 2.3% dividend yield. Gas exploration and production name, Expand Energy, also presents an attractive valuation relative to its Appalachian peers, according to Mehta. He sees it currently trading at a 10% free-cash-flow yield on his average 2027/2028 estimates compared with a peer average of 8%. Expand Energy, which yields 2.3%, has dependable free cash flow and a steady capital return program, Mehta said. Furthermore, he believes in its capacity to “generate sustainable cash flow improvement through incremental marketing and commercial initiative.” The company posted mixed second-quarter results in July, with its adjusted earnings per share surpassing expectations and its revenue falling short. Shares are down roughly 10% so far in 2026. U.S. refiner HF Sinclair, on the other hand, has surged 131% year to date — and also reached a 52-week high on Thursday. Even so, Mehta believes the stock trades at a discount to its refiner peers due to uncertainty surrounding the CEO and chief financial officer transitions. Both positions are currently interim. “[W]e continue to see value in the company’s non-refining earnings contributions (Lubricants, Renewable Diesel, and Midstream) in addition to the company’s leverage to niche refining markets (West Coast/Rockies and Mid-Continent),” Mehta wrote. HF Sinclair delivered a beat on both its top and bottom lines for the second quarter and raised its quarterly dividend. The stock currently yields about 2%. Mehta’s $114 price target implies 7.5% upside from Wednesday’s close. Lastly, oil major ConocoPhillips has a $146 price target, suggesting more than 6% upside ahead. Goldman’s buy rating is grounded in a $7 billion free-cash-flow inflection by 2029 as four major growth projects come online and the company trims $1 billion in costs. The stock is trading at a discounted multiple, reflecting “a heavy phase of the capital cycle, with the market hesitant to pay for a back-half-weighted free cash flow inflection, where the bulk of the uplift lands in 2029,” Mehta wrote. ConocoPhillips has gained 45% year to date, hitting a 52-week high on Thursday. It currently yields 2.5%.
