A smart phone’s low battery warning is the only warning that most people take seriously. Try the following steps and you will improve your battery life.
1. Let there be less light
For larger smart phones, the longer the screen is on and the brighter it is, the faster you
r battery goes. Try making the screen as dark as you can bear it and still read a text. Darkening the screen is common among teenagers, but it may be hard for Mom and Dad to see what’s showing on their phone.2. Turn off the signals
Your smart phone does a lot of communicating in the background. They’re checking for things like new emails, text messages, Wi-Fi signals, Bluetooth signals, your location and more. These activities do drain your battery life, so you should turn off whatever you aren’t using. Location Services is also another feature that burns up your battery, so you can use
GPS and Wi-Fi to find out which apps have access to Location Services and turn them off.3. Turn off notifications (通告)
Another way to improve battery life is to stop the constant flow of notifications and updates from Facebook, email, games and sites. Your phone will automatically pick up these notifications when it’s connected to the Internet, and they can have a noticeable impact on battery life.
4. Use battery saving mode (模式)
For a quick way to improve your battery, simply put your smart phone in Airplane Mode. If Airplane Mode is too limiting, some phones have a specific battery saver mode. This shuts down unimportant functions and apps like Wi-Fi, some updates and more.
If used properly, these tips above will improve your battery life up to 30 percent.

Picture the scene: the battery on your mobile phone has run out． You can't make any calls for help and no one can contact you． You are all alone - well, not quite． Just reach into your pocket and take out a piece of sugar．Put it into the battery, wait a minute, and you're back on the phone．
Thanks to a couple of American scientists, this situation could become real．Swadesh Chaudhuri and Derek Lovely have invented the"bacteria battery" - powered by bacteria that eats sugar and turns it into electricity．
"This is a special organism," Lovely said．"You can harvest enough electricity to power a cell phone battery for about four days from a spoonful of sugar．"
In the past, bacteria batteries have been expensive and not long-lasting． But this battery uses more efficient bacteria that can turn 80 percent of sugar into electrical energy． This is 30 percent more than similar batteries can manage．
The bacteria battery could become as small as a household battery． It's also cheap and stable, as sugar can be taken from waste and crops．
But the sugar to electricity process is slow: it could take weeks for the bacteria to digest a cup of sugar．And it produces "greenhouse" gases which pollute the environment．
The scientists understand there is a lot more work to be done． "It is still young," said Lovely．"Where we are now is where solar power was 200r 30 years ago．"
But he believes the battery could be used in scientific equipment at the bottom of the ocean．Other ideas include using sugar in the blood to run medical devices in the human body, and taking sugar from animal waste to provide energy to power homes in rural areas．
1.This passage is mainly about_ ．
A． how to change sugar into electricity
B． a scientific invention of a new kind of bacteria battery
C． a new way to reduce pollution caused by mobile phones
D． a new kind of mobile phones and its future
2.Which of the following is not the strong point of the newly-developed battery?
A． Convenient． B．Stable． C． Inexpensive． D． Quick．
3.The underlined sentence in the 7th paragraph actually means ．
A． the bacteria battery shares some similarities with solar energy
B． scientists will continue their work until they find solar power
C． there is much room for the improvement of the bacteria battery
D． the bacteria battery will get popular in 20 0r 30 years
4.According to the passage, who will find the bacteria battery less useful?
A． Farmers． B． Divers． C． Doctors． D． Electricians．
