Phone batteries play a crucial role in sustaining the energy needed for mobile devices to operate. Thanks to phone batteries, the active time of phones can extend from a few hours to several days, depending on the battery quality and user usage frequency. The more calls and web browsing, the faster the phone battery depletes. Here are some ways to preserve your phone battery that you should follow.
2.1. Keep the battery at 50%
Do you think maintaining a fully charged battery at 100% is the best? In reality, keeping the battery at a high level for a long time can reduce its lifespan and capacity.
If you are not using the battery for an extended period, the best way to preserve it is to keep it at 50%. This advice is widely supported by many researchers and is a general consensus. Advice from a leading global phone manufacturer: If you stop using the device for 6 months or more, keep the battery at 50%. This advice applies not only to batteries installed in devices but also to backup batteries.
2.2. Avoid letting the battery stay at 0% for too long
Avoid keeping the battery fully charged, and especially, do not let the battery drain to 0% for an extended or frequent period. If this happens repeatedly, or if you let the battery drain for weeks or months, the battery may become 'dead' and irreparable.
Remember, 50% is the ideal figure for preserving the phone battery when not in use. At some point, when you want to restart the phone, the battery can still function well.
2.3. Avoid frequently draining the battery
Have you ever wondered why your phone notifies you about a low battery when it reaches around 20% and prompts you to connect to a charger? This is not by chance; manufacturers intentionally set it up this way. Most modern devices nowadays use Lithium-Ion batteries. The distinctive feature of these batteries is that they shouldn't be frequently depleted (used to 0%) but are suitable for shallow discharges. The ideal range is 40% – 70%, then recharge. Avoid letting the battery drop to 20%, as it's not beneficial for the battery lifespan.
2.4. Avoid storing the battery at extreme temperatures
Extreme hot or cold temperatures are detrimental to electronic devices and phone batteries. Besides reducing the battery capacity, inappropriate temperatures can also damage the battery. While high temperatures can cause the battery to swell, cold temperatures will reduce the battery lifespan when you use it again at normal temperatures.
It's best to store the phone battery at room temperature, around 25-30 degrees Celsius. Avoid placing it near heat-producing devices like heaters, refrigerator circuits, hot and cold water machines, etc.
2.5. Don't charge your phone overnight
Nowadays, smartphones are quite 'smart' and can automatically stop charging when the battery is full. However, did you know the best way to preserve smartphone battery life is to avoid keeping it at 100% overnight or connected to the power source for too long? When the battery is full, stop charging. This helps maintain the battery life effectively.
2.6. Avoid using the phone while charging
Using your phone while charging immediately depletes the charged battery. If this happens repeatedly and for an extended period, it will quickly degrade the battery. The battery may drain rapidly even if it's relatively new. Additionally, it poses a danger to users due to the risk of explosion with low-quality chargers or phones. Have you heard about accidents related to phones exploding while being used and charged at the same time?
3. Tips for preserving your phone battery during extended periods of non-use
a. Remove the battery from the phone
Of course, this can only be applied to phones with removable batteries, the 'brick' types. Since most modern smartphones have non-removable batteries, removing the battery (if possible) will help prolong the battery's lifespan without directly affecting the phone.
b. Turn off the phone
For various reasons, many people don't use their phones for weeks or months. The best way to preserve the phone battery during long periods of non-use is to turn off the phone (if the battery cannot be removed). Turning off the phone will temporarily stop all background applications, preventing battery drain during the idle period.
4. Tips for preserving the battery of a newly purchased phone
In the past, with older phone models, employees used to advise you to charge your phone continuously for 8 hours in the first 3 times. The purpose was to help the phone get a 'full charge'.
However, since 2016, Li-Ion batteries have become widely used for most types of phones. The standout feature of this battery type is that you no longer need to continuously charge for 8 hours. It's no longer meaningful. You just need to charge the battery to 100%.
Therefore, the best way to preserve a new phone battery is:
Use the original charging accessories that come with the device
Use up the phone's battery before charging. 'Using up' means when the phone signals 'low battery' and needs charging, not using it until it reaches 0%, causing the phone to shut down. This will quickly reduce the lifespan of the phone battery.
Avoid leaving the phone charging overnight or for too long. Ideally, after the phone indicates a full battery, leave it for an additional 5-10 minutes before unplugging.
Certainly, over time, the battery will degrade. The level of battery degradation depends on your storage and usage practices. Typically, after about 1000 charge cycles, the battery will degrade by 20%. One charge cycle is counted from when the battery is fully charged to when it's completely drained.
The principles for preserving an iPhone battery, preserving a Samsung phone battery, or any other phone, are fundamentally the same. Hopefully, the mentioned tips for preserving the phone battery will help extend its lifespan, ensuring your beloved device operates more efficiently. Wishing you success.
