Lithium-ion batteries hate two things: extreme cold and extreme heat. With cold, repeatedly charging a smartphone in sub-freezing temps can create a permanent “plating of metallic Lithium” on the battery anode, according to BatteryUniversity. You can’t fix that problem, and doing it too much is only going kill the battery faster.
The battery is not alone in hating heat: all the internals of any smartphone don’t like it. It’s a computer in there, and computers and hot air are enemies going back decades. Leave your black iPhone sitting in the sun as you laze by the pool someday, and don’t be surprised when it throws a warning at you that it needs to cool off. In the summer, keep it off the dash of the car, preferably in the shade.
Apple specifically says charging iPhones over 35 degrees C/95 degrees F will do permanent damage to the battery; expect the same with any modern smartphone.
Best thing to NEVER do: Don’t let it get too cold or hot when charging. And don’t put the phone in the freezer. That’s dumb.
The one thing all the experts agree upon is that smartphones are smart enough that they do not let an overload happen. Extra protection chips inside make sure that doesn’t happen in a tablet or smartphone or even a laptop. Once the internal Lithium-ion battery hits 100 percent of its capacity, charging stops. That usually happens within an hour or two, tops.
If you leave the smartphone plugged in overnight, it’s going to use a bit of energy constantly trickling new juice to the battery every time it falls to 99 percent. That is eating into your phone’s lifespan (see below).
The best thing to do: Don’t worry about this too much. Plug the phone in when you go to sleep; if you wake up sometime in the night, unplug it to prevent constant trickle-charging. If you don’t wake much, plug your phone into a smart home outlet that you put on a schedule so it turns off.
Potential problems that could be encountered while charging overnight:
1) It is hot in here? The trickle charge can cause some heating up. Many experts recommend taking a phone fully out of the case to charge overnight. At the very least, do NOT stack a bunch of crap like books or other devices on top of a charging device. And for the love of Jobs, don’t put it under your pillow. Do any of the above and you can expect the phone to get hot—not necessarily enough for spontaneous combustion, but at least enough to damage the battery (see below). If you are afraid of fire, some in the UK recommend leaving the charging device on a dish or saucer while plugged in, or put it on something metal that is more likely to disappate heat, like a heatsink does on the chips inside a PC.
2) Bad Cables. If you’re using a knock-off cable that isn’t from the manufacturer, or at least “certified” in some way (iPhone Lightning cables should be MFi certified, for example), it could be a problem. The cord and connectors may not be up to the specifications needed for the phone or tablet. Don’t skimp by buying chintzy cables.
It will not damage your battery.
It will shorten its life though, but there is nothing practical you can do about it.
Lithium Ion batteries age in two ways, one is through what is termed “Calendar Life” and the other is Cycle life. Here is what you need to understand about both:
Calendar life – the time spent at a given state of charge (SOC) and a given temperature causes a loss of capacity and increase in internal resistance that is proportional to the square root of the time. Higher SOC imparts greater degradation. Higher temperature imparts greater degradation. Keeping your computer plugged in all the time with the battery ensures that the battery stays hot and charged as much as is possible. If nothing else, turn down the performance of the laptop when you don’t need it to overperform so that it runs cooler.
Cycle life – while you might think that it makes sense to fully discharge the batteries, rather than put lots of little cycles into it, the opposite is true. Lots of little cycles do virtually nothing to the cells. 100% discharges are the bane of their existance.
So, the reality is, you could optimize battery life by keeping the battery about 50% charged, letting it discharge a bit and then recharging it, and if chargers allowed for it, floating them at a SOC that was not 100%. However, it is much much easier to just get on with life and use your laptop and not worry too much about this. Assume your battery costs you $1 a day. Put that much away for its replacement. When it is fine on the day you buy your next computer, you have now paid for that new computer, or a good size chunk of it.
You’ve probably heard some people say you should drain your battery completely before charging it, or that you should keep it between 40% and 80% all the time to make it last longer.
Most of these rules are outdated, applying to older nickel-based batteries. Luckily, most or all of your gadgets these days run on Lithium Ion batteries, which are easy to take care of.
They last longer when you perform shallow discharges, keep them cool, and don’t leave them plugged in while they’re running at 100%. Honestly, though, batteries have a finite life no matter what, and your efforts will only go so far—so don’t stress about it.
Focus your efforts on getting better battery life out of your phone or laptop on a given charge instead—and knowing how to replace the battery when it starts dying.
Apple’s MacBook, MacBook Air, and MacBook Pro laptops don’t have a battery slider, although many of the same settings described above are present in the Energy Saver preferences.
To open it, click on the Spotlight magnifying-glass icon in the upper right corner of the screen, search for Energy Saver, and then click on the Battery tab. If you want to approximate the Windows Better Battery or Battery Saver modes, make sure that the options “Put hard disks to sleep when possible” and “Slightly dim the display while on battery power” are checked, and the option “Enable Power Nap while on battery power” is unchecked. (With Power Nap enabled and your MacBook asleep, the machine will wake up now and then to check for updates. Disabling it keeps your MacBook fully asleep when it is asleep—until you choose wake it up.) On recent MacBook Pro laptops, the display brightness adjusts to 75 percent when you unplug the computer from power if you have “Slightly dim the display while on battery power” enabled.
So, if you want the best battery life, should you use Battery Saver all the time? Not exactly. Because Battery Saver mode disables some useful features, you might want to use it only when your battery is below 20 percent and a power outlet isn’t near. Likewise, turning off Power Nap can mean it will take longer to catch up on notifications you’ve missed while you’re away from your MacBook. That’s why most users should use the Better Battery setting and enable Power Nap most of the time.
The first stop on our battery-life betterment tour is the Windows battery performance slider, a recent addition to Windows 10. It aims to group all of the settings that affect battery life into a few easy-to-understand categories. The company that made your PC determines exactly which settings the battery slider controls. But in general, keep these guidelines in mind:
- The Best Performance mode is for people willing to trade off battery runtime to gain performance and responsiveness. In this mode, Windows won’t stop apps running in the background from consuming a lot of power.
- The Better Performance setting limits resources for background apps, but it otherwise prioritizes power over efficiency.
- Better Battery mode delivers longer battery life than the default settings on previous versions of Windows. (It’s actually labeled “Recommended” on many PCs.)
- Battery Saver mode, a slider choice that will appear only when your PC is unplugged, reduces the display brightness by 30 percent, prevents Windows update downloads, stops the Mail app from syncing, and suspends most background apps.
1. Control Panel – Power Management Options – High Performance – Change the schedule settings.
2. Find [Change Advanced Power Settings] in the pop-up window.
3. Adjust the brightness of the plan to be max. Wireless Adapter Settings – Energy Saver mode, all set to [Maximum Performance].
4. Turn off the low battery notification. This is very important. Low battery level notification – off.
5. Click Apply, OK, then close all computer programs, wait for the battery to fully charge, and make sure the computer is using an external power supply.
6. Unplug the power cord and consume power in the standby state until it is turned off. Then plug in the power cord directly, then turn it on again.
The correction method for the laptop battery is shared here, without using any third-party software, the operation is very convenient! If your laptop battery is always full, try correcting your laptop battery.
1, first open the computer driver wizard
2. After opening, click to detect the computer driver;
3. Click “Hardware Detection” at the top after checking.
4. Select “Battery Information” on the left;
5, you can see the battery loss of the battery.
The above is the way to check the laptop battery loss. If the user wants to maintain the battery, he can use the power adapter to power on, instead of using the laptop battery to discharge. The laptop battery is a lithium battery, and its life is based on charge and discharge. of.
The first trick brightness setting
The display screen is also a large power consumer, we can reduce the brightness of it to achieve the purpose of power saving. First, right-click on the desktop, then select the “nVIDIA” or “ATi” control panel from the pop-up menu, and lower the brightness value in the “Brightness” option.
After testing, the editor can save about 3W power consumption after lowering the screen brightness, which is equivalent to reducing the standby function by 14%.
The second trick is to turn off unnecessary peripheral devices.
First, enter the BIOS settings of the notebook (press F2 to enter during startup), and in the Advanced option, turn off some of the peripheral devices that are not available at the conference (Disabled). These devices are: Wireless LAN, mouse, and camera. After turning off these unnecessary devices, the editor found that it can save about 2.2W of power consumption, which is equivalent to a 10% reduction in standby function.
The third trick is to close the CPU core.
Many friends think that turning off the multi-core of the books can also save power. Is this the case? We also did a test, shutting down the three cores and leaving only one job. And surprised! In fact, the stupid power consumption has not decreased much. Turning off the CPU core will only increase the load on the processor (such as 4 people’s live, become a person) and does not reduce functionality.
The above is the tutorial on how to save power in the win7 pure version of the notebook battery. The above method can help you to extend the power supply time of the notebook when you need to use the laptop urgently, saving a total of 24% of power consumption. Of course, the best way is to connect the power supply or prepare an auxiliary battery to prevent power outages, so you won’t be afraid even if the game is played for a long time.
1. Right click on the Win logo in the lower left corner of the screen and select “Command Prompt (Administrator)” from the pop-up menu.
2. At the command prompt, type powercfg /batteryreport /output “D://ianChi.html”. Among them, the storage path of the battery usage report file in the bold part can be customized, and you can also save it to other locations;
3. After the carriage return, the system will prompt the file to be saved successfully;
4. Open the corresponding folder and double-click to open the battery usage report file.
5. Under Installed batteries, you can see the factory design capacity of the battery and the current full charge capacity (that is, how much power can be stored when the battery is fully charged. If the computer is used for a long time, this will be different from the factory design capacity. Degree of loss);
6. Under the Recent usage item, you can see the battery charge and discharge situation in the last three days (including when it is activated and when it is in standby mode);
7. Next is the statistical chart of the usage.
8. Finally, focus on the last battery life estimates. Here is an estimate of how long the battery life can last.
After installing the tutorial step content settings, win10 laptop battery health status knows how it is, you want to know the status of your laptop battery, directly refer to this method to view it.
