Today, cell phones have become indispensable for each of us, but do you know what to do if you want to prolong the battery life? The following article will guide you on how to extend battery life. If you understand how to do it, you can optimize battery life easily.

Steps

Method 1 of 3: Extend Time Between Charges

1. 

   Turn off the phone. You should only turn off your phone if you do not use it for many hours as turning on / off will consume a lot of energy. This is the most effective and simple way to protect your phone's battery. Why? This will help conserve energy and charge the phone. If you don't want to listen to the phone while sleeping or after work, switch it off. Do the same when in an area with no signal (for example, on a subway or in remote areas, because the device will drain the battery rapidly when constantly tuning).
   • Some phones have automatic power saving functions, but the downtime can last up to 30 minutes so it consumes a lot of battery. If you are using a smartphone and in an area with no signal, set the phone to flight mode.

2. 

   
   
   Stop looking for signals. When you have a weak signal or no signal, the phone continuously scans and uses a lot of power. You will understand this if you forget to turn off your phone while on the plane. The best way to prolong battery life is to always leave your phone in a good signal area. If the signal is weak, you can buy a booster to amplify the signal anywhere or simply leave the phone in airplane mode (as mentioned before).

3. 

   
   
   Don't Follow the method of fully charging and discharging the battery. Avoid letting the phone shut down. Unlike nickel batteries (such as the AA NiCd or NiMH rechargeable batteries commonly found at supermarkets), lithium batteries are designed to be charged early and often, so that the power level drops too low can affect the battery's life. With lithium batteries, recharging frequently and not depleted will prolong battery life.

4. 

   
   
   Turn off your phone's vibrate mode. Use ringtones only. A vibrating phone consumes energy. You should also set the ringtone to the lowest volume possible.

5. 

   Turn off phone backlight. Backlight makes it easy to see the screen in bright weather or outdoors. However, the backlight consumes a lot of energy. If you can look at the screen without using it, it will prolong their battery life. If you need to use the backlight, many phones have a function to set the time to turn on the light, you can shorten the time using the light. Usually, only 1-2 seconds is enough to see. Some phones also have ambient light sensors, which automatically turn off the backlight in well-lit conditions and turn on the light when it's dark.

6. 

   Avoid unnecessary functions. If the battery is running low, do not use the camera or access the network. Photographing consumes energy quickly.

7. 

   Talk on the phone briefly. How many times have you heard someone say "My phone is going to shut down" but still try to say for a few more minutes. Sometimes saying your phone is about to power down is just an excuse to turn it off (and quite effectively) but if you really want to protect your phone's battery, limit your talk time.

8. 

   Turn off Bluetooth. This feature drains the battery rapidly. Turn on Bluetooth only when needed.

9. 

   Same goes for WIFI, GPS or infrared functionality, if your phone has the above features built in. Turn them off when not in use.

10. 

    Reduce screen brightness to the lowest possible level.

11. 

    Adjust network settings when possible. Use 3G (HSPA, HSPA +, UMTS) or 2G (GSM) instead of 4G (LTE). Turning on 4G on your phone will drain the battery faster when using 3G and 2G. Turn off 4G (LTE) when in areas with poor signal. When using 4G, both 3G and 2G are turned on so the phone uses a lot of power. You can turn off 3G and use 2G when the 3G signal is not good.

12. 

    On smartphones, avoid using animations or videos as wallpaper. Live wallpapers will drain the battery quickly.
    • Use a black background image if possible. The AMOLED screen consumes less power when the screen is set to black instead of white.

Method 2 of 3: Extend Battery Life

1. 

   New battery launch. It is recommended that you fully charge a new battery before using it to maximize its capacity. Nickel batteries usually charge about 16 hours and repeat the full-charge process 2-4 times, while lithium ion batteries should only charge in about 5-6 hours. Please ignore the battery full notification as it is not correct with the new battery.

2. 

   Avoid depleting lithium ion batteries! Unlike Ni-Cd batteries, lithium-ion batteries last less each time you drain them. You should charge the battery with one bar remaining. Lithium-ion batteries, like other rechargeable batteries, have a charge level.

3. 

   Cool the battery. Put the battery in the refrigerator. Battery life will last longer if you keep your battery at room temperature, and there is nothing more harmful than continuously using it at high temperatures. If you can't control the weather, you can avoid leaving your phone in your car or in direct sunlight, you don't need to keep your phone in your pocket because body heat will increase battery temperature. Also, check the battery while it is charging. If the battery gets too hot, the charger may be damaged.

4. 

   Charge the battery properly, suitable for each type of battery. Most newer cell phones use lithium-ion batteries, and some older models use nickel batteries. Read the information on the back of the battery or the specifications to determine the type of battery.
   • Nickel batteries (NiCd or NiMH) generally do not experience the misleading "memory effect". As described on Wikipedia and many other in-depth sources, the term "memory effect" is used to refer to damage to NiCd batteries (and other chemical batteries), but in many cases the user misunderstands them. to deterioration of battery life due to improper discharge and charging.
   • Lithium-ion batteries can be stored if they are carefully charged and stored separately. You do not need to "fix" them.
   • Regardless of the battery type, use only one charger and stop charging if it becomes too hot.

5. 

   Store batteries properly. If you do not use the battery for a while, remove the battery from the phone and store it in a cool, dry place without freezing (it can be stored in the refrigerator compartment, but not in the freezer). Do not put together metal objects that could move and short the terminals. Lithium-ion batteries do not work in cold temperatures, so you need to take them out for a few hours before using them. The lithium-ion battery oxidizes at 40% charge and is stored. Do not store batteries in low voltage. Recharge the battery after storing.

6. 

   Clean the battery contacts and the phone. Over time, the contact part can become dirty, which reduces the efficiency of energy transfer. Clean them with a cotton swab or use the solvent IPA (isopropyl alcohol). If the contact part is made of two different metals, such as gold and tin, corrosion known as "charged or needles" will occur. You will need to use a solvent such as acetone or nail remover to remove corrosion from contact parts. Be careful: the solvents dissolve plastic, so use a Q-Tip to avoid damaging the battery cover or the phone. advertisement

Method 3 of 3: Battery Failure Index

1. 

   Find out ways to avoid damaging the battery:
   • The use time after recharging is shortened.
   • The battery becomes unusually hot during a recharge process.
   • The battery becomes unusually hot while using the phone.
   • The battery face is swollen. You can confirm by touching or looking at the battery cover. At the same time, when placing the battery on a flat surface, it will sway or rotate. A good battery case is flat and doesn't turn around easily.
   • There is a hard spot on the battery. You check by pressing your finger on the surface of the battery.

Advice

• Check if your phone has the "Battery Saver" function. If so, turn it on to extend battery life.
• When charging, place your phone on non-heat absorbing objects such as wooden tables, plastic shelves, books, metal desks (because it is a conductor of heat, it will lower the battery temperature).
• When you plan to restart your phone because of network issue, try turning airplane mode off and on first as booting up takes a lot of battery.
• If your phone connects to email, be sure to turn off mail checking every 15-30 minutes. This means that every time you check mail, your phone consumes energy. Set do not test to save battery power.
• You should not turn off the phone to charge the battery. Most chargers give your phone more power than usual and charge it simultaneously. Turning off the device also does not shorten the charging time without seeing the fuel gauge, not knowing when the battery is full.
• When using a car charger, do not charge it when the car is hot. Wait until the car is cooler before plugging in the charger.
• Activate battery saver mode and charge the battery. Do not overcharge as it reduces battery life, you will have to buy new batteries.
• Turn off phone screen when calling.
• Leaving airplane mode on while charging may shorten the time, but depends on the charger you use and the internal circuitry of your phone.
• If you are in a place where there is no wifi, turn off the wifi function.
• Charge the battery to 80% and then charge again when it is 40%.
• Do not use your phone for a long time while it is charging, as it may damage the battery and charge. Also causes the phenomenon of "memory effect".

Warning

• Avoid exposing the phone to the sun. Prolonged exposure to direct sunlight will affect battery performance.
• Do not care the lithium battery at low voltage for a long time, the battery tester will collect small data leading to battery depletion condition 'damage the battery.
• You should only turn off your phone if it's only for texting and not making calls. If you use it often, don't turn off your phone unless absolutely necessary, because people will call your cell phone if you're not at home but can't be contacted when something important.
• Do not throw old batteries in the trash. Batteries contain a lot of harmful substances, and excess power in the battery and other electronic components will become a serious problem. Improper battery disposal is illegal in many countries.
