10 tips to make Apple Watch life last longer


It's not really a problem for me that the run out of my Apple Watch battery life. This is never an issue for me. But it doesn't mean that you shouldn’t know how to get more out of your battery. Here's what to do...


You should disable those snippets of information you get when you swipe your Apple Watch grab data from your iPhone. Although these information don't use too much energy, but just do so if you will need more battery life. Do so in My Watch>Glances, where you just need to tap the red minus button beside any less important apps.


Turn off unwanted notifications – this makes sense because each new notification you receive will launch the Taptic Engine, which uses a little power to give you motion feedback. Limit notifications to only your most essential info in My Watch>Notifications where you can flick those you don’t need to mirror to off.


Reduce Transparency and use the Reduce Motion tool in My Watch>General> Accessibility, you will lose some of the visual appeal of the product but you might get a few critical minutes.

Turn your Apple Watche display to Grayscale in My Watch>General>Accessibility, this can same a lot of power.


Launch the Settings app on your watch, open Sounds & Haptics and turn Prominent Haptics to Off. You may also save a little more power by reducing Haptic Strength using the slide control in Sounds & Haptics. My Watch>Sounds & Haptics is the place to go to limit the energy your watch uses giving you haptic feedback.

Volume & brightness

Reduce Alert Volume and display brightness in the Sounds & Haptic settings to make your watch a little longer. You can do so on either your watch or iPhone.


Disable the automatically download any aiavilable Apple Watch equivalents of any apps you have installed on your iPhone. You can do so in General> Automatic Downloads, toggle the Automatically Download Apps button to off.


Your Watch uses power when it tracks your workouts using its built-in sensors. Launch My Watch>Workout and toggle Show Goal Metric to off and enable Power saving Mode to disable the heart rate sensor. While doing so means calorie burn calculations will be less accurate, you will save a little more battery life.

Airplane Mode

Enabling this mode (in the Connected frame) on your Apple Watch or iPhone will immediately apply it to the companion device. You will still be able to use some apps but you will no longer receive messages, alerts or calls on either device.

Power Reserve

Your last option to keep your watch working, Power Reserve, is accessed when you  press the side button on the Watch until the power dialog appears. Just tap Power Reserve to enable this – now your Apple Watch will only do one thing for you, tell the time. But perhaps that’s all you needed, after all.

Daimler commits to release its own line of home batteries to take on Tesla

Daimler, Mercedes-Benz and smart parent company, has announced that it will release its own line of batteries for homes and small businesses within this year. The batteries will be available exclusively in Germany initially, but Daimler wants to gradually expand the market to other European countries and, possibly, the United States in the medium-term future.

Daimler executives explained quickly that the decision to enter the home battery market isn’t a direct response to Tesla’s recent announcement. The company outsources production of the lithium-ion battery packs found its in hybrids and electric vehicles to a wholly-owned subsidiary called Accumotive, which has also been building high-capacity battery packs for large commercial and industrial applications since 2012.
Chemically speaking, Daimler’s home battery is closely related to the lithium-ion battery packs found in the company’s cars. The battery works just like Tesla’s: Ideally mounted on a wall, it can be charged during off-peak hours when electricity is cheaper and turned on during peak hours when it is more expensive. Two or more batteries can be combined if extra capacity is needed, and homeowners looking to seriously trim their power bill can link the installation to solar panels or wind turbines.

Will The Alumium-Ion Battery Be Widely Applicated At Electronic Device?

Researchers at Stanford announced what many saw as a breakthrough in battery technology at April 6. It appears that there are several advantages of the aluminum-ion (Al-ion) battery over lithium-ion (Li-ion) batteries, the current standard for laptops, smartphones and other rechargeable devices:

1.Safety. Li-ion battery is a explosive materials that may burst into flames, which has led to a number of recalls since their introduction in early 90s. The video Stanford released shows researchers drilling a hole through their prototype without eliciting so much as a snarl.

2.Flexible. As Scientific American explains that the battery’s aluminum metal anode (negative side) is divided from its graphite foam cathode (positive side) by a liquid electrolyte separator, which, in consumer terms, translates into a pouch as bendable—even foldable—as an underfilled ketchup packet.
3.Can be fully charged incredibly fast. Researchers managed to charge a smartphone in a minute using their prototype while Li-ion batteries require hours to fully charged.
4.Much more charging cycles, completing over 7500 charge cycles without losing capacity, compared to the typical Li-ion battery’s 1000 cycles. Previous cracks at developing an Al-ion battery usually only managed about 100 cycles.

5,Lithium is much expensive than Aluminum.
According to the advantages said above, you might be saying, eureka, they’ve done it. Unfortunately, it may be too early to declare a breakthrough yet.


The Al-ion battery’s energy density is a quarter of the typical Li-ion battery’s, according to Scientific American reports. Additionally, as Stanford chemistry professor Hongjie Dai admits, his team’s prototype “produces about half the voltage of a typical lithium battery.” He remains optimistic, however: “improving the cathode material could eventually increase the voltage and energy density.”

The same issue would likely make the Al-ion battery a no-go for smartphones and other portable devices, despite the fact that that application has generated much of the media buzz so far.

10400 mAh USB battery with water and shock resisting

This UNIFUN USB battery is the sturdiest pack I've found and my favorite portable battery yet. It is perfect for use on a bicycle, motorcycle or camping.

I do not trust the charging system on one of my motorcycles, and for long road trips apps like Waze and evidently the podcast player run down my iPhone 6 pretty fast. Over a multi-day trip, this pack allows several full recharges of my phone. It is also small and tough enough to allow me to put the battery in the handlebar mount, and ride with the two connected. I'm not worried the constant buzzing of my bars, or random rainstorms, will damage the battery.

While slightly larger than its less rugged cousins, this battery will hold up to some adventure. It offers 2 USB charging ports, one a higher speed 5v/2.1A and one the other 1.5v/1A, and a flashlight.

Guide of RC Battery: Lithium-Polymer Batteries Basics Part

With many advantages such as low weight, high energy density, and ever greater discharge rates, Lithium-Polymer (LiPo) batteries have been wodely used on RC. The emergence and continual improvement of these batteries has provided an excellent performance boost for RC cars, boats, airplanes, and helicopters, while also paving the way for new vehicles such as multi-rotors. All of this electric goodness does not come without a cost. If not handled and utilized properly, LiPo batteries can quickly become damaged or even catch on fire. Today, I would like to share some basic things you should know about making the most of LiPo batteries. I will also provide techniques to mitigate the risks that these batteries pose.

When talking about a LiPo, it's neccessery to know the primary characteristics to understand the battery’s voltage and capacity. This is typically noted in a shorthand such as “4S-2200”. In this case, “4S” denotes that the battery has four cells in series. The nominal voltage of each cell is 3.7 volts (4.2v fully-charged), so the total pack voltage is:

4 cells x 3.7v = 14.8v.

The "2200" means the capacity of the battery in milliamp-hours (mAh). A fully charged 2200mAh pack can provide a current of 2200 milliamps (2.2 amps) per hour before it is fully discharged. This capacity value is completely independent of how many cells are in series. In simple terms, the capacity value allows you to estimate how long a battery will provide useful power in a given application. In practical terms for RC use, the capacity rating is typically only helpful for rough comparisons of different batteries. i.e. a 2S-5000 battery will provide about double the run time of a 2S-2500 lipo in the same RC car.

It's quite common when it was 10 years ago, while is now rare to find a RC LiPo battery that uses cells in parallel. Let’s look at an example in case you happen across one. A 4S2P-2200 battery would consist of two 4S-1100 batteries wired in parallel to provide a total 2200mAh capacity. All other things being equal, you would care for and use this battery the same as you would the previous 4S-2200 example (which is really a 4S1P-2200, but we ignore the 1P). There may be a difference in physical size, but a 4S-2200 and a 4S2P-2200 are functionally equivalent. The differences will really only matter to the guy at the factory who has to assemble the battery.

A huge changed has been occured at the Grid the way

Currently, large power plants generated most power and provided to consumers. Electric energy storage offers a double-way flow of power that makes some obvious advantages for support of the power grid. For example, storage is particularly useful for offsetting the intermittent nature of wind and solar photovoltaics, which don’t produce power on demand as a fossil fuel power plant does.

Having a battery behind the meter provides a great deal of flexibility in  energy using manage for an individual consumer. Consumers are allowed to cut their electric bills by reducing how much power they consume during peak hours when waste a high power costs, which is usual situation in many states such as California.

Houses with rooftop solar panels on the top and batteries can actually use energy from their solar systems during power outages and, with The right amount of storage, have sufficient power to last for days if the grid is out. And with enough storage, they can disconnect from the grid indefinitely – a development utilities fear.

Some states have net metering, programs in which utilities purchase the excess electricity from solar panels that’s fed into the grid. In combination with net metering, behind-the-meter storage creates the opportunity for customers to buy power from the grid when prices are low and then sell stored energy from batteries when prices are high. This practice, known as arbitrage, has led to concerns at utilities which have levied large additional charges for equipment installations in some places.

Commercial and industrial customers stand to benefit from behind-the-meter storage as well. They can reduce their usage during times of peak demand and cut so-called demand charges – fees for maximum power usage – that can dominate how much they pay for energy.
