Lihium ion battery

Some people charge their mobile phones daily. Others insist on letting the power completely drain away.

But, either way, mobile phone owners will do anything to prevent their batteries from running out. Now, experts have given their verdict: if you want your battery to last, don?t chargeit all the way.

Technology enthusiast, Eric Limer, from website Gizmodo, claims that a full charge is not good for phones. In fact, he said they should be unplugged before they reach 100 per cent.

?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,? he explained.

?That said, it?s smart to do one full discharge about once a month.? Running down the battery this way apparently helps to reset the phone.

Limer said users should try to keep batteries charged up to 50 per cent, if possible ? but warned that leaving phones plugged in after charging causes the battery to wear out.

In general, the optimum charge level is between 40 per cent and 80 per cent, he said.

He also debunked the myth that you should charge a new phone for 72 hours before use so that it ?remembers? what it is like to be fully charged.

This apparently works for nickel batteries, but not the lithium-ion type in new phones.

He said, ?Battery memory is a real thing, but it applies to nickel-based batteries.

?Your trusty sidekick doubtlessly has a lithium-ion battery and it needs to be treated a little differently. It should be topped up whenever you get the chance.?

You can also protect your battery by keeping your phone cool, he said.

The recommended storage temperature for most batteries is 15C (59F), while the maximum safe temperature is typically between 40C and 50C.

He added that at an average temperature of 25C, a lithium-ion battery will lose 20 per cent of its maximum capacity every year. At 40C, it jumps to 35 per cent.

As a result, it is best to avoid wireless chargers: ?The inductive, wireless chargers out there have this nasty habit of generating a fair bit of waste heat. That heat will toast your battery,? he said.

Day to day, you can extend battery life by turning down the brightness of your phone?s screen and turning off applications that use GPS, such as maps.

In areas with poor signal, turn on airplane mode to stop your phone from wasting charge searching for a connection. It can also help to lock your phone when not in use and use a quiet ring signal.

Top tips for boosting battery

Your phone works best from 0? to 35?C. Keeping your it as near room temperature as possible (22? C or 72?F) is ideal.

Viewing usage statistics

Awareness of how you use your phone and knowing how long your battery typically lasts can help you improve its battery life. Typically you?ll see two items:


Amount of time the phone has been awake and in use since the last full charge. The phone is awake when you?re on a call, using email, listening to music, browsing the web, or sending and receiving text messages, or during certain background tasks such as auto-checking email.


Amount of time the phone has been powered on since its last full charge, including the time the phone has been asleep.

Update to the latest software

Always make sure your phone has the latest software.

Optimise your settings

Depending on how they are configured, a few features may decrease your phone battery life. For example, the frequency with which you retrieve email and the number of email accounts you auto-check can both affect battery life.

Adjust brightness

Dimming the screen?s brightness extends battery life.

In addition, turning on Auto-Brightness allows the screen to adjust its brightness based on current lighting conditions.

Turn off push notifications: Instead of automatically syncing accounts, manually sync them instead to save battery life.

Minimise use of location services:

Applications that actively use location and GPS services such as Maps reduce battery life.

Use Airplane mode or flight mode in low- or no-coverage areas: Because your phone always tries to maintain a connection with the network, it may use more power in low -or no-coverage

Lock Your phone

Lock your phone when you?re not using it. You will be able to receive calls and text messages while it is locked, but nothing happens if you touch the screen.

Use your phone regularly

For proper maintenance of a lithium-based battery, it?s important to keep the electrons in it moving occasionally.

Be sure to go through at least one charge cycle per month (charging the battery to 100% and then completely running it down).
