London: Want to extend the life of your cell phone's battery? Do not charge your mobile to 100 per cent!
Mobile phones should be charged only about 50 per cent in order to prolong their battery life, a tech expert has claimed.
According to technology expert Eric Limer, rather than ensuring phones are constantly charged or running down the battery completely, the best thing to do is keep batteries running at about 50 per cent.
Limer said as overcharging, or having a full battery, and going from down to zero does gradual damage to phone batteries, 'The Telegraph' reported.
Keeping a phone too hot by constant charging can cause it to lose power every year, he said.
"For the most part, going from all the way full to all the way empty won't help; in fact, it'll do a little damage if you do it too often," said Limer.
"It is smart to do one full discharge about once a month," Limer said, adding this resets the phone.
He said that leaving phones connected to a charger after they are fully charged can do damage to batteries, as can high temperatures.
The best temperature for phone batteries, according to Limer, is about 15 degrees Celsius, and batteries kept at an average temperature of 25 degrees Celsius lose about 20 per cent of their power every year.
Limer also advised turning phones to airplane or flight mode in areas with poor signal, using a quiet ring tone and turning off applications that use Global Positioning System (GPS) as a way to conserve battery life.
Experts have also dispelled the common notion that new mobile phones should be charged for hours before using them, as this no longer works with the new types of batteries which are made from different materials and don't have the same "memory."
