Sometime in the nearest future, phone batteries will charge in a few seconds, last for months,

and get energy through Wi-Fi! Sounds great, but that time is yet to come. (Hey, I’m

Reflexive pronouns

holding out for the four-day work week myself) ! For now, people have to try other ways to

save battery life. Let's figure out if such methods as switching off Wi-Fi really work!

- If you need to save your phone's battery, switching the device off won't do the trick,

especially if you're planning to use it again in an hour or so. The whole switching on/switching

off thing takes too much battery power. At some point, your phone's screen just won't

light up anymore because trying to save energy, you've drained the battery completely.

- If your phone is running low, turning on Airplane Mode will indeed help to make the

battery last longer. This function shuts off cellular, Wi-Fi, and Bluetooth connection,

which saves a lot of energy. It's especially effective when you're in the area without

a proper cell signal. If you don't turn on Airplane Mode, your phone won't stop looking

for a signal, and it will drain the battery shockingly fast.

- Turning off location services can prolong your almost-empty battery life. The worst

thing is that you may not even realize that some of your apps are using this feature behind

your back. But anything that needs GPS navigation, for example, taxi services, particular games,

or even social media apps, will effectively wear your smartphone's battery out.

- Turning off vibration on your gadget can help you to save a bit of battery charge.

Both Silent Mode and an audible signal need far less power than vibrations.

- Closing background apps to make the battery last longer won't do you any good. Background

apps don't mean "running apps." It only means that they're in a state where you can easily

re-launch them again. They don't use much of your battery resources. Closing and opening

them again needs way more power and drains your battery very fast.

- Your phone's display needs a lot of energy to animate moving wallpapers. However pretty

and entertaining they are, try not to set them as a background. The fewer colors your

background has, the more energy-saving it is. The screen needs more power to render

numerous bright colors than it does while dealing with a black-and-white or three-color

background. - There is a belief that if you freeze your

phone, you'll be able to prevent lots of battery problems. In reality though, you should protect

the battery from any extreme temperatures, both hot and cold, because they can drain

your battery in no time. And by putting your phone into a freezer, you shorten its battery

life altogether. - Fast charging isn't for everyday use. It

does top off your battery amazingly fast, but it also wears it down more than regular

charging. Try to use this method only when you're in a hurry.

- I bet your smartphone's screen looks great, all big and bright. No surprise that it's

also a massive battery drain! Even if your battery isn't running low, go to the display

settings and turn the screen brightness down. Both the battery and your eyes will thank

you. Disabling auto-brightness can also come in handy - then your display's brightness

won't get higher than you want it to be. You can also choose how long your screen should

stay active: the shorter this time is, the more battery you save.

- If you know your phone's battery is about to run low, and the next charge is nowhere

in sight, try not to use the camera, especially with the flash on - it needs way more power

than any other app! - Turning off push notifications can also

help to make the battery last longer; otherwise, every time a notification arrives, your phone

will light up and waste its battery charge. If you still want to get some apps' notifications,

open Settings on your smartphone and choose Notifications. There you can tap those apps

- Energy-saving apps look like a great way to prolong your battery life! They clamp down

on unnecessary tasks, shut down faulty programs that draw too much energy, and close apps

that insist on launching themselves and downloading updates. Is there a catch? If you download

an energy-saving app advertised in another app, you'll most likely get malware that can

later steal your personal info. Battery-saving apps should be downloaded only from authorized

stores, and only after you read other users' reviews.

- The phone battery won't last longer than two years. That's a myth too many people believe

in. How long the battery will serve you depends not on time but on charge cycles. Most smartphone

batteries these days have a lifespan of about 300 to 500 cycles. You may assume that every

time you fill up your phone, you waste one charge cycle, but that's not exactly so. One

charge cycle is when a battery discharges from 100% to 0%.

- That's why letting your smartphone's battery discharge completely before charging it again

is a bad idea. From the time it's produced, a lithium-ion battery (which is the battery

used in your device) remains in a state of permanent internal corrosion. And it's normal

that over time, it can't hold so much charge. If you always wait until your phone's battery

fully discharges before "feeding" it again, it wears out much faster than it's designed

to. It's better not to let your battery drop below 25%.

- If you aren't using Wi-Fi, switch it off, and you'll save your battery. But is it really

so? Wi-Fi is far less battery-hungry than the cellular connection. If there is a Wi-Fi

network somewhere nearby, your phone will indeed try to connect to it. If not, your

gadget will keep searching for a suitable Wi-Fi network, but it will sip only a bit

of battery power. Turning off your Wi-Fi also means that your

gadget will use cellular data. It won't only drain the battery faster, but it will also

cost you quite a lot if you don't have an unlimited data plan. Switching off Wi-Fi on

your smartphone only makes sense if you're going on a long trip with no Wi-Fi networks

along the way. And if you just travel between home and work or run some errands, there's

no problem with leaving Wi-Fi on. - Another valid reason for not switching off

your phone's Wi-Fi is the Wi-Fi Positioning System. If your GPS uses Wi-Fi, not cellular

connection, your battery will last longer! In some places, such as big shopping malls,

GPS signals may get blocked or become confused. While trying to get back on track, GPS navigation

will empty your battery in no time. But if you connect to a safe local Wi-Fi network

(with the key word being "safe"), it will help you to navigate your way through the

mall. - I won't probably surprise you here, but

Power Saving or Low Power Mode DOES help when your battery is running out. Depending on

your software, this mode can limit different phone functions, from reducing the processor's

speed to turning off all push notifications. But here's the thing: in SOME phones, lower

speed means that apps take longer to finish tasks, put more strain on the processor, and

consume more energy. The whole power-saving idea defeated.

- Switching off auto-downloads and uninstalling unnecessary apps is an effective way to save

battery. In your settings, you can also opt for your downloads to occur only over Wi-Fi

- it will prolong the battery charge as well. And make it a habit to look through the apps

on your phone and delete the ones you don't use anymore. However little energy they consume

throughout the day, it may still add up with time.

- Facebook, Twitter, Instagram, and other social media are some of the most potent battery-draining

apps. Even when you aren't using them, they keep updating data. That's why every time

you open one of them, you see fresh information. You can deal with this problem by, for example,

opening Facebook in its browser mode or choosing to fetch data less frequently or manually
