Necessary arrangement of maps in social science subject and graph paper in mathematics subject should be done by the district administration / corporation along with the test papers.
Keeping your gadgets charged is easy in the short term. Just keep an eye on their battery levels and plug them into the wall when they gets low. But keeping your gadgets’ batteries healthy in the long run is a much more complicated proposition. The lithium-ion batteries that are in virtually all of our gadgets are chemically destined to degrade over time, holding less charge than they used to, and blowing through what little they have faster then before. It’s impossible to stop this process, but it is possible to slow it.
To find out the best ways to postpone the inevitable, we talked to Isidor Buchmann, CEO and founder of Cadex Electronics and main contributor to extremely in-depth and invaluable online resource Battery University, about how exactly you should treat your batteries in a perfect world, what you can do to maximize their life.
So brace yourself, because here’s what you’re probably doing wrong.
Is it bad to charge my phone to 100 percent?
For optimized battery life, your phone should never go below 20 percent or never above 80 percent. It may put your mind at ease when your smartphone’s battery reads 100 percent charge, but it’s actually not ideal for the battery. “A lithium-ion battery doesn’t like to be fully charged,” Buchmann says. “And it doesn’t like to be fully charged and warm.”
Is it bad to run your phone down to zero?
Letting your phone reach zero percent (aka, die) is not great for the long-term heath of its battery. This is because each time it reduces the number of cycles left on its Lithium-ion cell. The fewer number of cycles, the less amount of charge it's able to hold and the shorter the life of the battery.
At what percentage should I charge my phone?
In a perfect world, your battery never goes below 20 percent, and also never above 80 percent.
Electric vehicles, with batteries that are required by various regulations to have a minimum operational life on the order of several years, make that prospect more feasible than it is for your phone by using drastically oversized batteries that are purposefully designed to never be fully charged. “You’ll typically charge to about 80 percent and discharge down to about 20,” Buchmann says. “In that mid-range use, you get far more cycles than if you fully charged and discharged as we do on our cellphones.”
Fast charging" is a convenient feature that allows smartphones to charge up to 50 percent in less than an hour. Maybe surprisingly, using a fast charger isn't actually all that bad for the long-term health of your phone’s battery.
How do I enable optimized charging on my phone?
Optimized charging is a feature on most smartphones designed to protect their longterm battery health. And it does a few things. It slows down the charging of your smartphone when connected to power and it stops charging your smartphone when at full health, both of which are healthy for your smartphone's battery. It can also delay charging your smartphone past 80-percent when, using AI, it predicts that your phone will be connected to power for an extended period of time (like at night); this way your phone stays in that "sweet spot" between 20-percent and 80-percent for longer.
To enable optimized charging on an iPhone (must be running iOS 13 or later): open Settings > select Battery > select Battery Health > turn on "Optimized Battery Charging.
Is it bad to charge your phone multiple times a day?
No. Lithium-ion batteries like to be charged in short spurts, so plugging in for five-percent here and 10-percent there is not only fine, but advisable. Cycling your phone from 100 percent, down to zero, and back up has a very limited utility in that it can “recalibrate” a battery if it’s doing strange things like dying out of nowhere when it claims to be decently charged, says Buchmann. “But other than that, it’s not advised to fully cycle lithium-ion.”
Is using a fast charger bad for my phone's battery?
Most new smartphones come with a feature called "fast charging," which means that when paired with a compatible high-capacity wall adapter, they can get a high-percentage charge quite quickly.
You might be thinking that faster charging speeds, and the heat that comes from them, are bad for the overall health of your phone, but this isn't the case. Degradation has more to do with the number of cycles your phone's Lithium-ion battery goes through than how fast it completes each cycle. No matter what, a phone's battery will degrade to about 80% percent after two years (or 500 completed charge cycles).
What's the worst thing for my phone's battery?
The worst thing for your phone's battery health is to have it warm and fully charged at the same time. So get your phone off the charger when at 100-percent (or turn on its optimized charging feature).
The most stressful thing that can happen to your phone’s battery during regular use is not, in fact, being discharged, or even being empty. “The combination of full charge and warm actually causes more stress than usage,” Buchmann warns. “If you’re in a car in the summer, don’t put it on the dashboard. Put it on the floor, or in the shade.”
Circumstances where your phone or laptop are fully charged and extremely hot should be relatively rare and, as such, relatively avoidable. Don’t leave your fully-charged phone in the summer sun! Perhaps the most dangerous recurring heat-and-charge combination is a laptop that is always plugged in and prone to running hot, in which case investing in a cooling stand may be a smart move in case you ever want to use your laptop away from its tether.

Is it OK to use a wireless charger?
Using a wireless charger if fine for your phone's battery life, especially if you maintain a charge that's between 20-to-80 percent.
While lithium-ion batteries don’t like to be hot when they’re full, Buchmann says recent studies on vehicle batteries suggest they do like to be warm while they charge and discharge, so your wireless charger is probably not terrible for your battery’s health even though it may create additional heat. And if it helps you stay within the 20 to 80 percent power band, that's a very good thing.
“For charging and discharging, the battery likes to be warm. Between 25 and 40 degrees Celsius (77-104 F),” Buchmann says. “But in storage, the battery should be cool, maybe 15 or 10 degrees Celsius (59-50 F).” Monitoring these temperatures constantly is a tall order and probably not feasible, but you can find apps that will take note of your batteries temperature and warn you if it hits extremes, which will at least help you avoid the worst scenarios.
Wireless charging is slower and less efficient than a hardwire connection. However, it’s not all bad news as charging your smartphone slower can actually be beneficial for your phone's long-term battery health.
Can I fix my battery if it's already bad?
If your phone's battery isn't great, the thing you can do before going about replacing it is to recalibrate it. This process does a "full cycle" — running your device's battery from 100% down to zero in one fell swoop — to determine if it really is that bad. While this is not great a healthy battery's long-term health, it can help provide a last gasp of clarity for a battery that's going senile.
