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.

NASA Admits Fault in Starliner Test Flight, Classifies It as ‘Type A’ Mishap
Remember the astronauts who were stranded in space for months? NASA says it’s close to identifying the «true technical root cause» of the spaceship malfunctions.
NASA has been investigating the now-infamous Boeing Starliner incident since the story dominated headlines in late 2024 and early 2025. The Starliner suffered malfunctions that stranded now-retired astronauts Suni Williams and Butch Wilmore for months. The agency has now released a report on what happened, taking responsibility for its role in the mission’s failure.
«The Boeing Starliner spacecraft has faced challenges throughout its uncrewed and most recent crewed missions,» said NASA Administrator Jared Isaacman in a NASA blog post on Thursday. «While Boeing built Starliner, NASA accepted it and launched two astronauts into space. The technical difficulties encountered during docking with the International Space Station were very apparent.»
NASA has now labelled the mission a «Type A mishap,» which is defined as a «total direct cost of mission failure and property damage greater than $2 million or more,» or where «crewed aircraft hull loss has occurred.» Both of those apply to the Starliner, which has cost the agency $4.2 billion to date.
Isaacman also released a letter addressed to all NASA employees on X. The letter outlined various issues with the mission, including a «prior OFT thruster risk that was never fully understood,» disagreements among leadership about Williams and Wilmore’s return options, and the agency’s delay in declaring the mission a failure, despite its high-profile nature clearly showing it was.
These sentiments were echoed in NASA’s press conference on Thursday.
NASA has committed to working with Boeing to make the Starliner launch-worthy again and has been investigating technical issues and addressing them since the mishap early last year. Isaacman admitted at the press conference that the «true technical root cause» of the malfunctions still hasn’t been identified, but NASA believes it is close to identifying it.
«We’re not starting from zero here,» Isaacman told a reporter during the press conference. «We’re sharing the results of multiple investigations that will be coming to light in the hours and days ahead. Boeing and NASA have been working to try and understand these technical challenges during that entire time period.»
A malfunction to remember
The crewed Starliner flight was delayed several times before finally launching on June 5, 2024. The crew experienced malfunctions en route to the ISS, including several thruster failures, which made docking particularly stressful.
The Starliner’s return was delayed by two weeks before finally being sent home without Wilmore and Williams, who were left stranded on the ISS until returning with Crew-9 in March 2025.
The Starliner’s story is far from over. NASA and Boeing intend to send the Starliner back to the ISS in an uncrewed resupply mission with a launch date currently set for April 2026.

How Team USA’s Olympic Skiers and Snowboarders Got an Edge From Google AI
Google engineers hit the slopes with Team USA’s skiers and snowboarders to build a custom AI training tool.
Team USA’s skiers and snowboarders are going home with some new hardware, including a few gold medals, from the 2026 Olympics. Along with the years of hard work that go into being an Olympic athlete, this year’s crew had an extra edge in their training thanks to a custom AI tool from Google Cloud.
US Ski and Snowboard, the governing body for the US national teams, oversees the training of the best skiers and snowboarders in the country to prepare them for big events, such as national championships and the Olympics. The organization partnered with Google Cloud to build an AI tool to offer more insight into how athletes are training and performing on the slopes.
Video review is a big part of winter sports training. A coach will literally stand on the sidelines recording an athlete’s run, then review the footage with them afterward to spot errors. But this process is somewhat dated, Anouk Patty, chief of sport at US Ski and Snowboard, told me. That’s where Google came in, bringing new AI-powered data insights to the training process.
Google Cloud engineers hit the slopes with the skiers and snowboarders to understand how to build an actually useful AI model for athletic training. They used video footage as the base of the currently unnamed AI tool. Gemini did a frame-by-frame analysis of the video, which was then fed into spatial intelligence models from Google DeepMind. Those models were able to take the 2D rendering of the athlete from the video and transform it into a 3D skeleton of an athlete as they contort and twist on runs.
Final touches from Gemini help the AI tool analyze the physics in the pixels, according to Ravi Rajamani, global head of Google’s AI Blackbelt team. which worked on the project. Coaches and athletes told the engineers the specific metrics they wanted to track — speed, rotation, trajectory — and the Google engineers coded the model to make it easy to monitor them and compare between different videos. There’s also a chat interface to ask Gemini questions about performance.
«From just a video, we are actually able to recreate it in 3D, so you don’t need expensive equipment, [like] sensors, that get in the way of an athlete performing,» Rajamani said.
Coaches are undeniably the experts on the mountain, but the AI can act as a kind of gut check. The data can help confirm or deny what coaches are seeing and give them extra insight into the specifics of each athlete’s performance. It can catch things that humans would struggle to see with the naked eye or in poor video quality, like where an athlete was looking while doing a trick and the exact speed and angle of a rotation.
«It’s data that they wouldn’t otherwise have,» Patty said. The 3D skeleton is especially helpful because it makes it easier to see movement obscured by the puffy jackets and pants athletes wear, she said.
For elite athletes in skiing and snowboarding, making small adjustments can mean the difference between a gold medal and no medal at all. Technological advances in training are meant to help athletes get every available tool for improvement.
«You’re always trying to find that 1% that can make the difference for an athlete to get them on the podium or to win,» Patty said. It can also democratize coaching. «It’s a way for every coach who’s out there in a club working with young athletes to have that level of understanding of what an athlete should do that the national team athletes have.»
For Google, this purpose-built AI tool is «the tip of the iceberg,» Rajamani said. There are a lot of potential future use cases, including expanding the base model to be customized to other sports. It also lays the foundation for work in sports medicine, physical therapy, robotics and ergonomics — disciplines where understanding body positioning is important. But for now, there’s satisfaction in knowing the AI was built to actually help real athletes.
«This was not a case of tech engineers building something in the lab and handing it over,» Rajamani said. «This is a real-world problem that we are solving. For us, the motivation was building a tool that provides a true competitive advantage for our athletes.»
