You’ve Probably Been Charging Your Smartphone The Wrong Way.
Quick draining out of the battery is one problem that every Smartphone user faces. While avoiding demanding tasks (ex games/video) and reducing screen backlight/brightness can help save precious battery life, a new study has found that you might be charging your smartphone the wrong way.
A site from battery company Cadex called Battery University has released a study proving that many people are charging their phones in way that will ruin their battery life in the long run. The report goes into detail describing wrong charging practices and why they are bad for your phone. The lithium-ion batteries in our smartphones are sensitive to their own versions of “stress” which could be damaging battery’s long-term lifespan.
If you want to keep your smartphone battery in good condition and go about your day without worrying about battery life, you need to change a few things. Battery University gave these guidelines for correct charging practices:
1. DON’T KEEP IT PLUGGED IN WHEN IT’S FULLY CHARGED
Remove your phone from the charger as soon as it is fully charged. Leaving your phone plugged in when fully charged is bad for battery life. Once your smartphone has reached 100% charge, it gets “trickle charges” to keep it at 100% while plugged in. It keeps the battery in a high-stress, high-tension state, which wears down the chemistry within. According to Battery University, “When fully charged, remove the battery. This is like relaxing the muscles after strenuous exercise.”
2. IN FACT, TRY NOT TO CHARGE IT TO 100%
Lithium-ion batteries does not need to be fully charged, nor is it desirable to do so. Battery University says, “In fact, it is better not to fully charge, because a high voltage stresses the battery.”
3. KEEP IT COOL
Don’t charge your battery at extreme temperatures. If you notice that your device gets hot when you charge it, take it out of its case. “Extreme cold and high heat reduce charge acceptance, so the battery must be brought to a moderate temperature before charging,” Battery University says. It will protect your battery’s health.
4. CHARGE YOUR PHONE PERIODICALLY DURING THE DAY. AVOID LONG CHARGING SESSIONS.
The study found that smartphone battery last longer if you charge them occasionally throughout the day, instead of plugging them in for a big charging session when they are empty. The report says charging your phone when it loses 10 percent of its charge is the best scenario.
