Ahead of the Galaxy Unpacked event on August 10, Samsung’s executive vice president teased the Galaxy Watch for those who are “passionate about the outdoors” and want to “strive to be the best version of themselves.”
While it’s unclear if these announcements are specific to the rumored Galaxy Watch 5, they suggest that Samsung is working on a smartwatch that’s more like one of the best Garmin watches than the Apple Watch 7.
Following rumors that Apple itself is working on an Apple Watch 8 Rugged and will launch alongside the upcoming Apple Watch 8, we wouldn’t be surprised to see Samsung diversifying its wearables portfolio to appeal to a wider range of client.
Galaxy Watch made just for you
As explained by Executive Vice President TaeJong Jay Yang (who also heads Samsung’s health R&D team), everyone has a different view of what health means. For some, it’s just about hitting a daily step goal and getting a little exercise, while for others it’s just about breaking last week’s PB to reach a new level of physical performance. It added that Samsung’s goal is to make technology that enables people to achieve their personal goals, no matter what they happen to be.
For those with more subtle goals, something like the Samsung Galaxy Watch 4 might be enough for you. There’s basic step counting and GPS tracking to keep track of how far you’ve walked, and BioActive sensors can track your heart rate and sleep patterns, giving you a comprehensive view of key health factors.
However, data collection and presentation from sensors can be too much for the average user, and features like body composition monitoring are better suited for those with more ambitious health goals. The Galaxy Watch may not quite meet all the needs of fitness fanatics, though, as those who enjoy the outdoors will want a fitness tracker that can take a beating better and has a longer battery life.
As a result, Samsung appears to be planning to launch a wider variety of watches, Yang said: “Samsung is excited to continue expanding our Galaxy Watch lineup to better meet the many unique needs of our users.”
Lithium polymer batteries are rechargeable and use polymer electrolytes as an alternative to liquid electrolytes. These lithium-ion batteries provide higher energy compared to other types of lithium batteries. In addition, Lipo batteries offer manufacturers a wide range of advantages, so a variety of shapes can be produced. They are used in serious applications requiring weight, including mobile phones, computers and radio-controlled aircraft. Lithium batteries have pros and cons, and there are some features to check before choosing a good battery. Let’s take a look below!
What are the advantages of lithium-ion polymer batteries?
Energy Density
Lithium-ion has twice the energy density of standard batteries. Additionally, the Lipo offers 3.6v, which is three times more than other rechargeable batteries like NiMH and NiCd. As a result, batteries are able to deliver higher currents for critical applications.
lack of memory effect
The memory effect is the process by which repeated charge or discharge cycles cause a battery to decrease in capacity. Li-ion polymers have no memory effect, which is a common effect in Ni-MH and Ni-Cd technologies.
low discharge rate
Lithium-ion batteries have an average discharge rate of about 1.5% to 2% per month. Additionally, they do not contain toxic cadmium; therefore, they are easy to handle.
safe
Many attempts have been made to manufacture rechargeable lithium batteries. This is because lithium metal is not stable during charging. To this end, research has shifted from metallic lithium batteries to non-metallic lithium batteries using lithium ions. Although lithium ion has a lower energy density compared to lithium metal, it is safe. Add safety measures by following precautions when charging or discharging.
low maintenance
Lithium-ion batteries require less maintenance than other batteries. Therefore, they do not need loops to maintain their life cycle.
What are the disadvantages of lithium-ion polymer batteries?
overheat
While lithium-ion technology is superior, it also has drawbacks. Batteries can overheat and therefore be damaged under high pressure. This problem can lead to burning and thermal runaway.
Security Mechanism
Lithium ions require safety mechanisms to reduce internal pressure and voltage. These issues tend to reduce performance and add weight.
fragile
Lithium ions are fragile and require protection circuits for added safe operation. The built-in protection circuit does not allow the battery voltage to drop during discharge. Most battery packs limit the maximum charge current and discharge to 1C and 2C. Eliminate lithium plating by following precautions such as monitoring temperature.
Ageing
Aging is a serious problem, and lithium-ion batteries age. That means the battery could fail within two to three years. However, other technologies also suffer from this problem. For example, nickel metal hydride ages rapidly when exposed to extreme temperatures. Store batteries in a cool, dry place to limit the aging process. The recommended temperature is 15 degrees Celsius. Also, charge the battery to 40% during storage.
transportation
Lithium-ion batteries have massive shipment restrictions and are therefore under control. However, this limitation does not apply to personal batteries. This applies to international and domestic shipments by sea, land and air. Also, the lithium content depends on the number and capacity of cells in each battery pack. Any lithium content above 1.5 to 8 grams per battery is classified as a hazardous material.
expensive to make
Lithium-ion polymer batteries are expensive to manufacture, about 40 percent higher than nickel-cadmium batteries.
How to choose a high-quality lithium-ion polymer battery?
The following characteristics should be considered when selecting a high-quality lithium-ion polymer battery:
capacity
The capacity of the battery is displayed in ampere hours. It can be increased by connecting batteries in parallel. Multiply the voltage by the capacity to get the amount of electricity stored in kilowatt-hours.
size
The correct size of the battery is calculated by calculating the daily consumption and dividing by the current voltage. You can get the minimum power by dividing the result by 0.5.
Voltage
Battery voltage is displayed in volts (V). The normal voltage is 3.6V/cell, and other manufacturers produce 3.70V/cell. For this reason, they gain a market advantage because high voltages add watt-hours.
Lithium-ion batteries have become the most promising and fastest growing batteries on the market. Today, such batteries are gaining acceptance from buyers. It also provides a huge electrochemical potential and gravimetric energy density. It is a safe battery and low maintenance.
Your battery is a rechargeable battery with a limited lifespan. These batteries gradually lose charge and sometimes take more time to recharge. If you want to extend the life of your batteries, you need to take good care of them. This means you should develop better charging habits and pay attention to battery storage. Below we will share some basic charging tips for Li-ion batteries.
Yes, it’s best to keep the Li-Ion battery charged. You can take care of the battery in these ways. You can leave your device powered up overnight.
This won’t be a huge problem if you don’t unplug the device right after charging it. That charger is smarter than you might think. You can leave the charger plugged in overnight or even all day. The charger will stop charging as soon as it is fully charged.
Charge your device as much as possible.
Lithium-ion batteries don’t respond well if you charge them and then use them to the last drop. If you charge them at appropriate intervals, you’ll get a good response from the battery.
Don’t let it get overcharged.
The biggest danger to your laptop battery, phone battery, and tablet battery isn’t overcharging, it’s heat. With that in mind, if you can, it’s a good idea to remove the laptop’s battery while it’s plugged into the wall. The trick is that if you’re using your computer without a battery, you’re in danger of shutting down in the event of a power outage or an unsuitable power adapter. Weigh your preferences.
If you can’t or don’t want to drain your laptop battery, at least make sure you have good airflow. Do not block cooling vents. The fan can even be pulled up with the stand.
Do Li-Ion batteries need to be fully charged the first time?
unnecessary. You don’t have to fully charge a Li-Ion battery the first time. Lithium-ion batteries have the highest usable range from the start, and a 1st charge is no different than a 10th charge.
All you need to do: Just plug in the charger and get started.
Normal use
Lithium-ion batteries have a lifespan of at least 300-500 charge and discharge cycles, typically 2-3 years. Throughout the life cycle, lithium-ion batteries typically experience capacity loss due to a variety of factors, including charge cycles, storage, temperature changes, usage patterns, and overall aging. To limit the risk of damaging the battery, use only the designated smart charger.
Hot and cold weather use
Lithium-ion batteries are comparable to humans in that none of them behave exactly the same, and they operate best at temperatures that are not too hot or too cold.
These batteries operate better at high temperatures than at low temperatures because heat reduces physical stability and speeds up chemical reactions inside the battery. A side effect of this method is that it puts stress on the battery, which can result in a shorter lifespan with continued use in hot conditions.
If your battery is at or below 50%, plug in the charger. You only need to charge your device’s battery when it’s fairly low, as having a fully charged battery all the time won’t enhance your device’s capabilities. If you want to check your device’s battery, look for the small battery icon in the menu bar. If you’re on a laptop, float over the icon to see the percentage. If you are using a smartphone or tablet, click the icon or expand the menu to see the percentage meter.

Lithium-ion batteries are rechargeable batteries commonly used in portable electronics. In a lithium-ion battery, lithium ions move from the positive electrode to the negative electrode during discharge and vice versa during charging. The positive electrode is made of intercalated lithium compounds, while the negative electrode is usually made of graphite. The two electrodes are separated by a thin layer of microporous plastic that prevents the two electrodes from touching each other.
Most explosions related to lithium-ion battery fires and explosions are caused by short circuit problems.
Some possible reasons for a separator to fail are:
Factory defect: The battery is poorly designed in this case. In some lithium-ion battery models, when the battery expands while charging, the electrodes tend to bend and cause a short circuit. Without quality control, even a well-designed battery can fail.
External factors: When lithium-ion batteries are placed too close to extreme heat, they tend to fail. Lithium-ion batteries will always explode if they are too close to a heat source or catch fire. Other external factors that can cause a battery to fail include dropping the phone too hard, which can damage the separator and cause the electrodes to come into contact. If you also pierce the battery, either intentionally or unintentionally, you have the potential to cause a short circuit.
Charger Issues: Chargers that are not properly insulated and poorly manufactured can damage Li-Ion batteries. If the charger generates heat near the battery, it can cause a lot of damage and cause it to malfunction.
Thermal runaway and multiple batteries: This is a typical battery with multiple batteries. Only one battery cell needs to fail for the entire battery to operate. Once a battery overheats, it causes an effect called thermal runaway.
Despite the aforementioned failures associated with lithium-ion batteries, it is still considered a safe and mature technology. Solutions for lithium-ion battery failures and explosions include:
1. Avoid exposing the battery to high temperature, such as placing the battery in a high temperature environment.
2. Avoid putting all devices that contain lithium-ion batteries together.
3. Avoid overcharging.
Can an uncharged lithium-ion battery explode?
Lithium is a reactive element that oxidizes when in contact with air, and reacts explosively when in contact with water. Uncharged lithium-ion batteries can explode because most of the materials in the battery are still highly flammable. It may not necessarily explode, but it can be quite unsafe in a fire.
Most cell phones, laptops, and several other electronic devices are powered by lithium-ion batteries. These batteries are generally very safe, but there is a risk of fire or explosion if not handled properly. The following steps can be taken to avoid battery explosion:
1. Buy your electronics from a reputable supplier with an excellent track record in safety and health.
2. Electronic devices usually come with a set of instruction manuals that explain how to use your device safely. These instructions can help you reduce your life-threatening risk of fire and explosion.
3. Always use the charger that came with the device. But in case you misplaced it, it is recommended that you buy a replacement recommended by the device manufacturer. Just because a charger fits your device doesn’t mean it’s safe to work. Using the wrong charger is one of the main reasons why lithium-ion batteries explode.
4. Electronic equipment should be kept away from extreme heat and cold. See extreme temperatures from the radiator or car dashboard on a sunny day. Placing your device in these places could cause an explosion.
5. Keep the equipment clean, dry and away from water.
6. Unplug your device when fully charged. Turn off the device when not in use.
7. Lithium-ion batteries should only be transported in specially designed containers. Batteries should be kept away from metals and other batteries. Lithium-ion batteries can explode when placed in pockets or handbags, and when bumped against coins and keys.
8. Modifying your equipment is dangerous and greatly increases the risk of explosion. Even experts can get hurt when tinkering.

Batteries are found in our vehicles, personal computers, CD players and other electronic devices. Due to the lack of battery maintenance, different problems can arise and be faced. Difficulties such as undercharging or overcharging are common problems, again due to lack of care. If the battery is not handled or maintained properly, the battery capacity may decrease. Early battery failure or abnormal sulfation can also occur if the battery is not properly maintained. Below is some information on battery maintenance, let’s take a look!
A battery is an electrical device and proper maintenance is critical to the battery to ensure its reliability. It is believed that if you neglect maintenance procedures, then you may shorten the life of the battery. Batteries like lithium-ion require little maintenance after initial setup, but other types of batteries, especially submerged lead-acid batteries, require regular maintenance to stay in good shape.
What are the steps in the battery maintenance process?
Proper battery maintenance procedures are often overlooked. Proper maintenance sequence is just as critical as the maintenance steps themselves when it comes to extending battery life and protecting your equipment.
Follow the steps below to properly maintain the battery:
1. The battery can only be charged when the power drops to 20%
The battery should not be allowed to drop to 20% before charging. Releasing the battery pack too far can damage the battery, always affecting its appearance and longevity. It can also overheat and damage the forklift’s circuitry. The battery should be allowed to charge without interruption. Charging for a short period of time before reaching 50% power can result in reduced performance and reduced battery life.
2. Balancer fees should be paid if necessary
This is the deliberate overcharging that many batteries require to function properly and efficiently. Battery chargers that require this feature will have a button that must be physically squeezed to turn on equalizer charging. For further instructions, consult your battery/charger manual to determine if equalizer charging is required, and if so, how often or how to provide equalizer charging. During the process of receiving the equalizer, the battery will charge for a longer time. The battery should be monitored during this process, as extended charging times may cause overheating.
3. Turn off and let the battery cool before removing
The battery should hit 100% before shutting down, not before that. This allows the battery to run more efficiently throughout the day. This also increases battery life and also reduces no. The number of times the battery needs to be charged. Damage to the battery and circuitry may occur if the battery is not cooled or may overheat before being put into service.

If you’re still emailing files from your iPhone to someone nearby, or you’re using a USB thumb drive to transfer a few photos from your Mac, please stop. Please use AirDrop instead. Whether you have an iPhone 13, iPad Mini or a new M1 MacBook Pro, AirDrop is the most convenient way to transfer files and content from one Apple device to another. AirDrop allows you to quickly share photos, documents, videos, recordings, contact cards, network links, and notes between Apple devices.
AirDrop is limited to iOS and MacOS. When AirDrop came out in 2012, it was one of the features that separated the iPhone from the Android phone. You don’t even need the latest iPhone 13 Pro or a 16-inch MacBook Pro equipped with an M1 Max chip to use AirDrop. It works on any iOS device running iOS 7 or higher and any Mac running OS X Yosemite or higher. The only “requirement” is that the distance between the two devices is within 30 feet, and both Wi-Fi and Bluetooth are turned on.
How to enable airdrop
On iPhone, make sure that Wi-Fi and Bluetooth are both turned on. Next, open the control center panel, and then press and hold the wireless connection icon until it expands into a rectangle. Click “Airdrop” and select “Close receiving”, “Contacts only” or “Everyone” to control who can send files to your phone.
On your Mac, check if you have Wi-Fi and Bluetooth enabled. Open a Finder window. Then, click AirDrop from the sidebar. A window with a radar-like graphic will open. Anyone nearby who has AirDrop enabled will appear in this window. At the bottom of the window, you can choose who can send you content.
How to airdrop on iPhone
To use AirDrop on iPhone, the person you want to send files to needs to have an Apple device with Wi-Fi and Bluetooth turned on. If any of you has enabled personal hotspot, please turn it off; otherwise AirDrop will not work. The same is true if you use a VPN.
Whenever you see the “Share” button on your phone, you can choose “Airdrop”. When you do this, you will see a list of all nearby Apple devices that also have AirDrop enabled. Tap the name of the device you want to send to. Find the person you want to send a photo to, and click their contact icon. Next, a reminder window pops up on the recipient’s phone, which contains a preview of the content you shared. They can choose to accept or reject. Once they click Accept, the photo you selected will be transferred. The pictures and videos will be saved to the photo application on the recipient’s phone.
If the person you want to send to has their AirDrop set as contacts only, then they need to have a contact card in the contacts app that contains your email address or phone number to make it work. If you are not in their address book, ask them to change their AirDrop preference to “Everyone” to receive your files.
How to airdrop on Mac
First, make sure that both Wi-Fi and Bluetooth on your Mac are turned on, and then open a Finder window. Next, click AirDrop from the sidebar. To share a file, simply drag and drop it onto the contact icon of the desired person in the AirDrop window. Also, just like on iOS, you can access AirDrop at any time when you see the “Share” button.
If you have trouble sending files via AirDrop on your Mac, click the “I can’t see the person you’re looking for” button at the bottom of the “AirDrop Finder” window. Then, click the Search Old Mac button that pops up.
How to airdrop from iPhone to Mac
If you want to airdrop content from iPhone to Mac, start with the content. For example, if you want a web link to AirDrop, please open that page on your iPhone. Then open the share menu and click on the AirDrop icon. Next, select the Mac icon and name of the device you want to send the web link to. The recipient’s Mac will display a prompt asking them to accept or decline. Once they click accept, the web link will be transmitted and opened in their default web browser.
If you want to airdrop from iPhone to Mac, and both are signed in to the same Apple ID, you will not see an option to accept or decline. The transfer will only happen.
How to change your AirDrop name
Your AirDrop name is the same as your generic device name. To check or change it on iPhone, open Settings. Tap “General” and then tap “About”. The first item in the list shows the current name of your iPhone. Just tap to change.
