Many users have noticed that after using their phones for a few days, the battery charges faster and lasts shorter. To make their phone batteries last longer, people often search online for tips on how to extend battery life. But did you know that many of these common charging practices are actually incorrect? You may have been following them for years without realizing it.
Should I wait until my battery is completely drained before charging?
No! “Deep discharge†can harm your battery.
In the past, there was a belief that older batteries had a memory effect, so you needed to fully drain them before recharging to 100%. Otherwise, the battery would "remember" the partial charge and fail to charge properly. However, modern smartphones use lithium-ion batteries, which are very different from the old nickel-based ones.
According to Wang Yonggang, an engineer from Tianneng Lithium Battery, a leading company in new energy power batteries, "deep discharge" — meaning letting your phone run out of power completely — can cause irreversible damage to the internal structure of the battery. This shortens its lifespan over time.
When charging, lithium ions move from the positive electrode through the electrolyte, across the separator, and into the negative electrode. Dr. Zhang Hua from UCLA explained this process with an analogy: it's like moving items from one room to another. Each time the battery charges or discharges, the lithium ions have to move, which puts stress on the battery structure. The more they move, the more damage occurs.
Is it safe to charge my phone all night?
No need to worry — lithium batteries have overcharge protection.
Many people believe that leaving their phone plugged in overnight damages the battery. However, modern lithium-ion batteries are designed with overcharge protection. Once the battery reaches 100%, it switches to a trickle charge mode, where it only receives a small amount of current to maintain the charge. This prevents overcharging and minimizes damage.
However, keeping your phone plugged in for extended periods can still affect the battery over time. Even though the phone isn’t overcharging, constant cycling between full and slightly lower charge levels can reduce the overall lifespan of the battery.
Does charging frequently damage the battery?
No — “shallow charging†is actually better for the battery.
Contrary to popular belief, frequent, short charges are not harmful. In fact, lithium-ion batteries perform best when they are charged in small increments rather than fully discharged and then fully charged. This is known as "shallow charging" and "shallow discharging." It reduces the stress on the battery’s internal structure and helps maintain its longevity.
Other habits that affect battery life
Using non-original chargers can be risky. These chargers might supply too much current, which can degrade battery performance over time. Always use the charger that came with your device or a certified replacement.
Also, using your phone while it's charging — such as playing games or watching videos — can lead to increased power consumption. If the phone uses more power than the charger provides, it will draw from the battery instead, effectively discharging it while it's supposed to be charging. This back-and-forth can shorten battery life.
Extreme temperatures also take a toll on batteries. High heat can speed up chemical reactions inside the battery, causing it to lose capacity faster. Cold temperatures below zero degrees Celsius can also damage the battery’s internal structure, potentially leading to permanent issues.
REMOTE CONTROL SOCKET
Important Safeguards
When using any electrical appliance, in order to reduce the risk of fire, electric shock and/or injury to persons, basic safety precautions should always be follow8d. including:
• The appliance is for household and indoor use only.
• Before plugging in. check that the voitage on the rating label is the same as the mains supply.
• To protect against electric shock, do not immerse any part of the product in water or other liquid.
• This socket is intended for use by competent adults only and children should be supervised at all times.
• Do not use the socket for other than its intended use.
• This socket can be used by children aged from 8 years arxl above and persons with reduced physical, sensory or mental capabilities or lack of experience and knowledge if they have been given supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children shall not p<ay with the appliance Cleaning and user maintenance shall M be made by children without supervision.
• Children of less than 3 years should be kept away unless continuously supervised.
Children from 3 years and less than 8 years shall only switch on/off the appliance provided that it has been placed or installed in its intended normal operating position and they have been supervision or instruction concerning use of the appliance in a safe way and understand the hazards involved. Children aged from 3 years and less than 8 years shall not plug in. regulate and clean the appliance or perform user maintenance.
• Don't use this socket in the immediate surroundings of a bath, a shower or a swimming pool.
• In case of malfunction, do not try to repair the socket yourself, it may result in a fire hazard or electric shock
Do Not Exceed Maximum a680W
Place the LR44 batteries provided into the compartment in the back of the Remote Control, please insert as sho*/m in the back of the compartment to ensure the polarity is correct.
Programming Instructions
• Plug the Remoce Socket$($)lnto the wall socket(s) and switch on the mams supply, the red LED will flash every second.
• If the LED is not flashing press & hold the manual ON/OFF button for 5 seconds until it Hashes
•Press any ON switch on the Remote Control for approximately 2 seconds and the Remote Socket(s) learn the code. The LED will stop flashing top confirm the codehas been accepted.
• Any number of Remote Sockets can be programmed to one Remote Control ON button to create multiple switching.
• To programme o<her Remote Sockets on different Remote Control ON buttons repeat the prevous steps
• If the mains supply is turned off the Remote Sockets v/ill lose their code and it wil be necessary to re-pcogramme.
Operation:
• Plug your appliance(s) into the Remote Socket(s)
• Press the programmed ON or OFF button on the Remote Control to control the Remote Socket.
♦ The Remote Sockets can also be operated manually using its ON/OFF Button Trouble shooting
If a Remote Socket does not react to the Remote Control please check the followng:
♦ Low battery in tbo Remote Control
• Distance too large between the remote control and the recerver (ensure the range distance is no more than 20 clear Metres) and free from obstacle that may reduce the distance.
• If programming has not been successful, tum the power off and back on then follow the programming steps above.
How to decode
• Press the manual ONX)FF button for 5 seconds until the red LED flashes once per
second to confirm de-coding is successful
♦ Press the ALL OFF switch on the Remote Control for more than 3 seconds, the LED
flashes once per second to confirm (decoding successful.
