Battery Health Tips: How to Make Your Phone Battery Last Longer
Gaurav Shukla Reviewed By Jordan Gloor
Your phone’s battery can last longer and perform better if you avoid extreme temperatures, charge smartly, use battery saver mode, and update your software. In addition, you can monitor battery health for any issues, turn off connectivity options you don’t need, and use a power bank to avoid draining it completely.
Many of us rely on our phones for work, relaxation, and staying in touch with loved ones, so it’s a good idea to do everything possible to avoid wearing your battery our prematurely. Here are some tips and tricks to delay its wear and tear and keep it in good condition.
Avoid Extreme Temperatures
Your phone battery is sensitive to heat and cold. So its exposure to high or low temperatures can shorten its lifespan or cause it to drain faster. You should avoid both scenarios if you want your battery to have a long life. Apple says storing your iPhone or iPad in temperatures between.20 degrees and 45 degrees Celsius (-4 degrees to 113 degrees Fahrenheit) is safe. Similar temperature ranges are valid for Android devices as well.
You don’t need to wait for your phone battery to hit zero to start charging or to reach 100% to stop. Charge as much or as little as you may need. This is because each battery has a limited number of charge cycles, and its performance will degrade, or it’ll completely stop holding a charge after reaching the charge cycles.
Frequent deep discharging, overcharging, and undercharging can impact the charge cycles, so it’s best to avoid them. You can also use features like “Optimized Charging,” “Adaptive Charging,” or “Optimized Battery Charging” to increase the battery life.
Update Your Software
Always ensure you are running on the latest version of your phone’s software, whether it’s Android or iOS. Software updates often bring optimizations to get the most out of your phone’s components, besides new features and security improvements. So if you don’t install an update, you may lose out on features or improvements that can increase the battery’s lifespan.
Use a Battery Health App
Battery health apps are quite helpful in determining the condition of your phone battery. They can tell you its maximum capacity, peak performance level, and general health. This information can be beneficial in changing your battery usage patterns to increase its life or understand why your phone is dying quickly after every charge.
While Apple includes an iPhone battery health feature in iOS, Android users can install third-party apps like AccuBattery. That said, some Android phone manufacturers, like Samsung, have built-in battery health tools.
Use Battery Saver Mode
Although there are some trade-offs to using a battery saver or low power mode, it’s excellent at reducing the overall power consumption of your phone.

This not only increases the backup time on a single charge but is also helpful in the long run. Almost every phone will ask you to turn one of these modes on once you reach 20% battery life, but you can also enable it at any time to take advantage of the energy-saving measures.
Use a Power Bank
When you are likely to stay away from an outlet for a significant duration, a power bank can help you avoid discharging your phone completely.
Remember, if possible, you want to avoid deep discharges, as they negatively impact its lifespan. And, of course, it’ll also charge your phone when you need it. We have several excellent recommendations for power banks.

Review: Anker PowerCore 10000 PD Redux.- USB-C portable charger
Portable chargers with a traditional USB connector are always useful for anyone with an iPhone or iPad. They are useful when you are away from the home or office, especially when traveling. And as many in the country (including me) were reminded last week, they are also very useful when you lose power at your home as a result of bad weather.
Nowadays, however, many devices can charge faster with a newer USB-C PD connection, which provides more power and can charge more quickly. Some devices even require the extra power that you get with USB-C. Earlier this year, after doing some research on the available portable chargers, I decided to purchase a device made by Anker called the PowerCore 10000 PDF Redux. After using this product for over a month, I’m incredibly happy with it and I highly recommend it. It is great for charging an iPhone or iPad, and it has even made my HomePod mini much more enjoyable.
This device is small and portable. It is just over 4” long, about 2” wide and about 1” tall. Because of the curved sides, it is easy to hold in a hand. The device weighs less than 7 ounces, so it adds a little bit of weight to a briefcase or purse, but not very much. You can definitely walk around with this device in your. if necessary.
The short edge of the device has two ports. One is a traditional USB port, which can provide up to 12.3 watts of power. The other is a USB-C PD port, which can provide 18.8 watts of power.
There is a single button on the top of the device. Press the button to see how much charge the device has, and between one and four blue lights will turn on.
The Anker PowerCore 10000 PD Redux charges itself using the USB-C port. Just connect a USB-C to USB-C cable (one is included) to any USB-C power adapter (which is not included), such as the power adapter that comes with an iPad Pro or the newer iPhone models. The PowerCore can recharge itself from 0% to 100% in about 3.5 hours. Anker says that you can also charge using a traditional USB charger, but that it will take 9 hours to charge. (I didn’t test that.) When the PowerCore is charging, the blue lights around the button flash, and you can see roughly how much the PowerCore is charged based on how many of the four blue lights are illuminated.
When the PowerCore is fully charged, you can use it to charge other devices using either the USB port or the USB-C port, making it incredibly versatile. I have found the PowerCore to be particularly useful for charging the following three products:
Use your own USB-C to Lightning cable (the one that comes with newer iPhones) to use the PowerCore to charge an iPhone. As the name indicates, it has a 10,000 mAh battery, which means that it will recharge a typical iPhone almost three times. And because it is USB-C PD charging, it charges my iPhone 12 Pro much faster than a traditional USB-to-Lightning charge. Nobody likes waiting for an iPhone to charge, especially when you only have a short amount of time to charge. Thus, the extra charging speed that you get with USB-C on the PowerCore is quite welcome.
Note that you can use the PowerCore to charge two devices at the same time by using both the USB-C port and the USB port, but when you do this, you lose the ability to fast charge on the USB-C port. Once you are done using both ports, unplug the USB-C cord and plug it in again to go back to the fast charging mode.
iPad Pro charging
With my 12.9 iPad Pro down to almost 0%, this PowerCore was not enough to get back to 100%. It got me to around 60% or so. Critically, however, if I started with a full 100% at the beginning of the day and then plugged in to the PowerCore as the power started to go below 50%, that was enough additional charge for me to make it through the end of the day for those days when I was using my iPad extensively during the day without plugging it into a wall outlet. Using a traditional USB charger with an iPad Pro is sort of a joke; all it really does is slow down somewhat the speed at which your battery goes down. But with USB-C on this PowerCore, I was able to use my iPad while the battery percentage also increased back up to 100%.
For both an iPhone and an iPad, in the past, I’ve found portable chargers most useful when I am traveling. I have not traveled during the past year due to the pandemic, but I find that portable chargers are now useful for another reason: independence. When I am working at home with my wife and two teenagers in the house, I typically use my iPad with an external keyboard. That’s how I am typing this post right now. In the past, I would have to make sure that my iPad (or iPhone) had a sufficient charge before I started to get work done; otherwise, I would need to find a place to work that was close enough to a wall outlet so that I could charge. But with the Anker PowerCore 10000 PD Redux, it really doesn’t matter how much charge my iPad has when I start. I can find any corner of the house to call my own, or even someplace in the backyard, to get work done. Whenever I need more power, the PowerCore is there to give it.
I’ve been using two HomePod mini speakers since my wife gave them to me as a present for Christmas. The HomePod mini has a built-in cord, which you cannot remove from the device, with a USB-C connector at the end. The HomePod mini comes with a 20W power adapter, and at first, it required 20W to power it, but in late 2020, Apple updated the firmware to support 18W charging. That means that you can now use it with the PowerCore, which provides just over 18W.
The Anker PowerCore 10000 PD Redux does a fantastic job charging the HomePod mini, so much so that it actually transforms the HomePod mini into a new device: a portable HomePod mini. I’ll discuss this more in my upcoming review of the HomePod mini, but suffice it to say that I love my HomePod mini much more now that I have the PowerCore.
Using a PowerCore to power a HomePod mini does not seem to take much power. I once played music for eight hours straight with my HomePod mini plugged into the PowerCore. When I started, the battery indicator on the PowerCore was at four out of four lights. When I finished, it was still at four out of four lights. I guess I could have kept the music playing for much, much longer.
This device shines when it provides a lot of power. But sometimes, you want to charge something that takes a very small amount of power, like a Bluetooth headphone or a Fitbit. When a portable battery like the PowerCore senses that not much power is being drawn from it, it may think that it is done charging and it will shut off for safety.
To help with this, Anker includes a Trickle-Charging Mode with this device. To activate it, press the power button twice or press and hold for two seconds. This causes the lights around the button to change color from blue to green. In this mode, this device will output much less power and will know that it is supposed to be doing so. Thus, you get all of the power that you need to charge something small that doesn’t need much power to begin with.
I’ve been very happy with the PowerCore 10000 PD Redux. It provides lots of power when I am on-the-go — which one day will mean when traveling, and for now mostly means just finding a place to get work done. And for my HomePod mini, this charger actually adds a new feature, turning it into a portable speaker that I can bring to the backyard. Because the this device is so powerful, I think it is perfect to keep in a briefcase or purse so that it is always there if you need it. And finally, I’ve had very good experiences with the Anker brand in the past, so this is a name that I trust.
If you are looking for a great, small portable charger for your iPad, your iPhone, or for any other device that can take advantage of USB-C, you should consider the PowerCore 10000 PD Redux. I’m very glad that I have it.

The Anker PowerCore 10000 PD Redux is the compact version of Anker’s 18W/10,000mAh power banks. The Redux model has a large, round button on top. Used for checking capacity and activating trickle charge mode. Unlike some older models, there are only 4 LEDs on the button, not 8-10. Don’t expect the circle to fill when recharging, the LEDs cover less than half of the curve. The top also has a grip-friendly surface. But the bottom doesn’t, lessening the gripping surface’s effectiveness.

Check with your device’s manufacturer to verify which charging standards it supports.
USB Power Delivery Quick Charge 4 Phones
- Apple iPhone 8/X/XR/XS/11/SE
- Essential Phone
- Google Pixel
- LG ThinQ/V30
- Samsung Galaxy S8/S9/S10/S20
- Samsung Galaxy Note 8/9/10
- Xiaomi Mi 8/9
- ZTE Axon Pro 9/10
Using an iPhone 8 for testing we find USB PD phones will fast charge over the USB-C port. iPhones will need to use a USB-C to Lightning cable, not included. And Android phones will need a USB-C to USB-C cable, which is included.
For older and newer iPhones the USB-A port supports Apple 2.4A. An older, but still functional fast-charging standard. Older iPhones (4-7) can fast charge using USB-A. Newer iPhones will charge ~15 minutes faster using USB-C.
Quick Charge 3.0 Phones
- Samsung Galaxy
- Xiaomi Mi 5/6
Using a Moto G6 for testing we get normal charging rates. As no Quick Charge or compatible fast charging standard is supported. The USB-A port provided for the faster charge rate, around 10W.
Works great for all model Nintendo Switch in handheld/tabletop mode. The rare 15V power profile support allows all model Switches to reach their max charge rate.
It will not support the Switch’s dock, as it doesn’t offer the required output.
15V Power Profile Support
A stand out feature of the Anker PowerCore 10000 PD series is the inclusion of 15V in their power profiles. Most other brands either stop at 9V or 12V. Which is fine for most devices. iPhone and Android supporting USB PD don’t need more than 9V. Smaller accessories stick with 5V.
The 15V is nice for larger devices, namely the Nintendo Switch and iPad Pro. Both of those devices accept and thrive at 15V. The original model Switch goes from 12W with a 12V option to 18W with a 15V option. Newer model Switches and the iPad Pro has less of a jump. But an increase in power max power draws nonetheless.
The 15V power profile isn’t enough to fully justify the cost of an Anker power bank. But if you’re trying to pick between it any other option it makes for a good tie-breaker.
Trickle Charge Mode
Anker PowerCore 10000 PD Redux in trickle charge mode
On the Anker, PD Redux press the button once to turn it on. Turn double press the button to active trickle charge mode. One of the four blue LEDs will turn green, indicating the mode is active. It’ll stay active for up to two hours. Or you can turn the mode off by pressing the button once.
No Fast Charging With Two Devices
The total output is limited to 18W. With no fast charging available when both USB ports are in use.
When you connect the second device you’ll notice the charging resets on the first. This is the power bank stepping down to a 5V output level. If you disconnect the second device you’ll want to unplug and replug the first. To make sure fast charging turns back on.
This limitation is typical of most power banks. The few I’ve seen which allow for two fast-charging devices are unusually large. There is a limit to how much current can cross its circuits without extra hardware. Which adds size, weight, and cost.
Most smaller devices will revert to their normal charging rate. Which will continue to charge the battery while they are in use. The total charge time for the two devices is about the same. Whether you fast charge them one at a time. Or charged them at a slower rate together.
The Anker PowerCore 10000 PD Redux has its pros and cons. Whether it is worth the price will depend on your personal needs.
Anker PowerCore 10000 PD Redux ports
On the upside, it offers a trickle charge mode for small accessories. Including Bluetooth earbuds such as Apple Airpods. It also offers a 15V power profile, making it a better option for older model Nintendo Switches. It includes a USB-C cable and travel pouch, but cable inclusion isn’t as exclusive to Anker as it once was.
On the downside, there’s no Quick Charge support. Making it less desirable for some LG and Motorola phones. Unlike previous Anker models, you lose fast charging support when using both ports. You will also pay a premium for the Anker brand and customer support. Worth it for some, but less so for others.
It’ll fast charge iPhone 8/X/XR/XS/11/SE, Samsung Galaxy, and Google Pixel. No fast charging for Quick Charge supporting Android phones.
All models of the Nintendo Switch can charge at or near their max rate. of an advantage for launch day model Switches.
Larger tablets, including the iPad Pro, will also take advantage of the 15V power profile. Though the 10,000mAh capacity is more limiting for those devices.
It comes bundled with a good USB-C cable and travel pouch, which can carry both a power bank and cable. Anker is renowned for their customer service. With 15V also supported on the input side you can use most of any USB-C power adapter to recharge it in a few hours. Including the Nintendo Switch’s AC adapter and older Apple USB-C power banks.
Anker has U.S. based support (web, email, phone) and an 18-month warranty. And their own online community with forums. They are a beloved brand within many USB-C communities.
The Anker PowerCore 10000 PD Redux offers the usual Anker quality and support. Including the needed USB-C cable and a decent travel pouch. Its 15V power profile offers better charge rates for some devices. But it has the same weak dual device charge rate as cheaper competitors.
Buy if you:
- Need to fast charge iPhone, Samsung, Pixel, iPad Pro, or Nintendo Switch
- Want to charge an original model Switch as fast as possible
- Prefer the Anker brand and customer support
Don’t buy if you:
- Need to fast charge a Quick Charge supporting Android phone
- Value price over potential performance drop
You’ll want a USB-C wall charger to quickly recharge this USB-C power bank. I recommend the Anker PowerPort III Nano.

Best Portable Charger Overall
INIU B62 Power Bank
Battery capacity: 15,000mAh | Output ports: 2x USB-A, 1x USB-C | Size: 5.8 x 2.8 x 0.9 inches | Weight: 11.7 ounces | Display: Yes
Best for: Charging smartphones and tablets quickly.
INIU is a less recognizable name, but its lineup of power bank and charging accessories stands out from the crowd. The INIU B62 has a single USB-C port that supports up to 45-watt output with USB Power Delivery. That means you can use this versatile battery for charging a low-power laptop or a portable gaming system.
This model supports a range of fast-charging protocols, but it only handles up to Qualcomm’s Quick Charge 3.0. If you want to charge a QC 4.0 device, look at the INIUs B5 Power Bank, which has a similar physical design, adds QC 4.0 and can charge three devices simultaneously (but it lacks enough power output to charge a laptop). The B62 has a large LCD that shows your remaining power, and it has a grippy texture that resists scuffs and grit. Bonus: It comes with a nifty pull-out stand that works well to prop up a phone while it’s charging.
What the editors say: Tech editor Melissa Perenson notes, “This battery is a workhorse, handily charging up devices with surprising speed. It recharges quickly, too. It’s a little thick, but its rectangular design pairs well with a smartphone.”
Anker PowerCore III 10K
Battery capacity: 10,000mAh | Output ports: 1x USB-A, 1x USB-C | Size: 5.9 x 2.7 x 0.8 inches | Weight: 8.6 ounces
Best for: Mix of wired and wireless charging, in a slim design and mid-range capacity.
The Anker PowerCore III 10K hits a good balance between features, performance and price. The svelte, candy bar design houses 10-watt Qi wireless charging, with one each of USB-A and USB-C ports on the top edge. This model is slim, but not as slim as one Anker model. Nor does it have the magnetic attachment of Anker’s newer MagGo series. Or the power to handle charging a laptop or gaming system.
Despite those caveats, the PowerCore III 10K stands out for its balance of charging features and its performance—which was faster for both wired and wireless charging than on some competing models. This battery pairs well with a standard rectangular phone design, and it’s lightweight, too. The unit itself has a textured plastic case that did a better job withstanding scuffs than some of Anker’s other models. The chassis also has a built-in stand—a simple pull-out bracket to prop up your phone. However, the recessed power button is a bit awkwardly placed.
What the editors say: “This model’s Qi wireless gives it an edge over the typical portable charger with the same capacity,” says tech editor Melissa Perenson. “I especially liked this battery’s light weight, and how easy it was to hold alongside an iPhone or Android phone.”
- Textured case keeps fingerprints and scuffs away
- Qi wireless charging at 10 watts
- Built-in stand
Best Portable Charger For iPhone
Apple MagSafe Battery Pack
Battery capacity: Unavailable | Ports: MagSafe (wireless) only | Size: 3.8 x 2.5 x 0.4 inches | Weight: 6.4 ounces
Best for: iPhone users who want a small MagSafe battery pack.
The Apple MagSafe Battery Pack is a bit pricey, but it is the Apple-branded battery—and it has a simplicity to it not found elsewhere. This compact battery pack attaches to the back of any iPhone 12 or later smartphone. It provides additional power when you need to extend the life of your smartphone. Thanks to its MagSafe compatibility. you can use the battery pack on its own or in conjunction with any Apple MagSafe phone case. It won’t, however, work with non-MagSafe cases.
This battery is a bit pricey considering it will only recharge your iPhone once—and only between 40 percent and 70 percent. However, that’s enough juice to keep your phone operational for a few hours more.
- Compact design for any iPhone (12 and later)
- Compatible with all MagSafe cases
- Genuine Apple product
Best Portable Charger With AC Outlet
Mophie PowerStation Pro AC
Battery capacity: 27,000mAh | Output ports: 2x USB-C, 1x USB-A, 1x AC | Size: 10.8 x 5.9 x 1.4 inches | Weight: 2.6 pounds
Best for: Capacious charging via USB and a 3-prong AC outlet.
The Mophie PowerStation Pro AC makes it easy to charge four devices simultaneously. At 27,000mAh, this model is at the maximum limit for transporting a single battery onto a plane. All that battery capacity matters, though, since it can recharge an iPhone five times. The 3-prong AC outlet is one reason this model stands out; with an outlet, you can then charge things like camera batteries, or run a laptop or other device that uses AC power.
The battery can handle 100 watts, while the USB ports handle 20 watts each and the USB Power Delivery port is at 60 watts. One drawback lies with its weight: The PowerStation Pro AC is a hefty 2.6 pounds. The battery has a loop that makes it easier to grab, which is good since its casing is smooth hard to hold.
Omnicharge Omni 20
Battery capacity: 20,000mAh | Output ports: Qi wireless, 1x USB-C, 2X USB-A, 1x AC/HVDC, 1x barrel | Size: 5.0 x 4.8 x 1.0 inches | Weight: 1.3 pounds
The Omnicharge Omni 20 is highly versatile, especially considering its relatively compact size. It includes a 20,000mAh capacity battery, fast 18-watt charging over USB-A, 60-watt charging over USB-C and 10-watt Qi wireless charging. The 100-watt AC/HCDC outlet provides power to laptops, drones and cameras that don’t support USB charging.
The Omni 20 has a built-in OLED display that shows the total power left in the charger, as well as the demands of each connected device. It even supports pass-through charging, so you can continue to charge your array of devices even when recharging the Omni itself.
- Offers pass-through charging
- 20,0000mAh capacity battery
- Portable and convenient
Best Portable Charger With Built-In Cables
Mophie PowerStation Plus
Battery capacity: 10,000mAh | Output Ports: 1x USB-C | Built-in cables: 1x USB-C, 1x Lightning | Size: 5.8 x 0.7 x 2.8 inches | Weight: 8 ounces
Best for: Charging a phone or tablet with a Lightning or USB-C port.
The Mophie PowerStation Plus conveniently integrates cables into the sides of the portable charger. This otherwise nondescript rectangle has smooth front and back surfaces, and it has a rubberized layer around the edges. The Lightning and USB-C cables tuck neatly into the top of the unit with a snug fit, and little tabs to help you free them when needed. The cables are long enough for you to plug them into a phone and stack the charger neatly beneath it.
This charger’s dedicated USB-C Power Delivery port delivers 20 watts of power, and a total of 25 watts shared. The USB-C port charges faster than the integrated cables.
Best Portable Charger For Laptops
Baseus Laptop Power Bank
Battery capacity: 20,000mAh | Ports: 2x USB-C, 2x USB-A | Size: 6.4 x 5.3 x 0.7 inches | Weight: 1.1 pounds | Display: Yes
Best for: Charging a laptop or mobile device.
The Baseus Laptop Power Bank stands out for delivering 100 watts of power in a thin and lightweight square design that’s highly portable. Most competitors’ portable chargers that output 100 watts are larger, thicker and heavier than this Baseus model. The low profile makes it easy to slide this charger alongside a laptop when traveling.
This fast, portable charger has a textured plastic front, with a large, monochromatic digital display that shows its remaining battery power and charging status. It can handle small current devices like earbuds and smartwatches as well as it can a phone or laptop. The ports are all along the top edge, with two USB-A and two USB-C ports, each labeled with their output levels. The unit comes with a carry case, and a 100-watt USB-C to USB-C cable, for use with a laptop.
What the editors say: “I like the stylish yet functional industrial design of this charger,” says tech editor Melissa Perenson. “It was easy to carry around while charging multiple devices quickly.”
- Slim, lightweight design
- Informative display
- Charges four devices simultaneously
Best High-Output Portable Charger For Laptops
Anker 737 Power Bank
