Cell phones can suffer battery drain due to various causes, including overheating, excessive use of certain apps and defective chargers.
Most of these problems can be avoided with some awareness and good habits. Here are 7 mistakes that drain cell phone batteries: 1. Utilizing it while charging.
1. Leaving Wi-Fi or Bluetooth On
Many users who utilize Bluetooth earbuds with their phones may not realize it can quickly drain battery power, as their phones will constantly look for other devices to pair with, which consumes energy.
Leave Wi-Fi turned on when not in use can drain the battery quickly, especially if your network is password protected and encrypted. To preserve battery power, reduce Wi-Fi use as much as possible while also avoiding websites requiring entry of personal information (e.g. online banking services) that require input.
Prolonging phone charging sessions too long may also cause it to overheat and shorten its lifespan, so for maximum battery health it is advisable to allow the battery to charge to around 80% before placing your phone back on its charger.
2. Leaving the Screen On
Leave your screen turned on can quickly deplete your battery, so reduce brightness on your device to help extend battery life. BetterBatteryStats or Battery HD+ apps provide useful monitoring solutions to track phone performance over multiple days and determine which apps consume the most battery life.
Push notifications can quickly drain a phone’s battery, so to save power it may be wise to disable them and even turn off location services in order to conserve even more power.
Avoid operating your phone in extreme temperatures as this could significantly impede its ability to hold a charge. Prolonged exposure can cause chemicals in the battery to degrade rapidly, leading to decreased performance and eventual battery death.
3. Leaving the Phone in the Car
Low smartphone battery can be alarmingly concerning for users, leading them to turn to car USB ports as an easy solution to recharge during their commute – but this can be highly dangerous.
USB ports in cars don’t provide enough electricity to fully recharge a phone (and could even cause it to stall), while leaving it inside exposes it to high temperatures and causes its battery to age faster than necessary. That is why it is best not to charge your phone in your car.
4. Leaving the Phone in the Sun
Smartphones can become overheated quickly when left exposed to sunlight for too long, potentially damaging themselves and even becoming inoperable. Extreme heat or cold can also have disastrous results on smartphones, so it is crucial that they are protected against all elements.
To reduce overheating, the best approach is to limit high-intensity programs, limit screen brightness and turn off background apps. Also try placing your phone in a cooler location like an air-conditioned room or shade to help bring down battery temperature faster; but do so gradually since extreme temperatures could lead to further damage.
5. Leaving the Phone on the Charger
Not uncommonly, your phone’s battery drains quickly. But it is essential that you identify what may be causing this and take steps to address and prevent future instances.
Some of these tricks are simple solutions, like turning off the flashlight or disabling auto-locking. You could also reduce screen brightness, disable features you don’t use and utilize low power mode to boost performance.
Another easy solution to improve battery health and lengthen its lifespan is charging only to 85 percent capacity before unplugging it. Over-charging can damage and shorten its lifespan.
6. Leaving the Phone on the Charger All Night
We’ve all heard the myth that leaving your phone plugged in overnight will drain it or even cause it to explode, yet this is far from being accurate or the best practice.
Battery researchers and reuse experts agree that it’s better to keep your smartphone partially charged rather than fully. Maintaining between 25-85% charging can slow the charging/discharging cycle and extend battery lifespan.
Lithium-ion batteries work by moving charge carriers from their graphite layer into lithium cobalt oxide and releasing power. Excessive heat or cold may damage these batteries, so be wary about leaving them in hot cars or near ovens for too long.
7. Leaving the Phone on the Charger All Day
Consumer electronics companies generally recommend charging your device between 20 and 80% battery capacity, as extreme battery charging can degrade it more than charging within its optimal range. Lithium-ion batteries have only so many charges they can accept from a charger before eventually ceasing to accept power altogether.
Lithium-ion batteries cannot be overcharged, and manufacturers provide safeguards to avoid this possibility. However, leaving your device plugged in all day could cause it to overheat, particularly if left under your pillow or near lights that generate heat.
