‘Hush’ kills unused apps to boost your battery: Free tool tracks how you use your phone to save energy
- Hush tool is available on Github for developers but will become an app
- Automatically stops rarely-used apps from running in the background
- Purdue University researchers said the Android tool can reduce the total daily energy drain by 16 per percent
If you are fed up of constantly closing apps in a constant battle to save smartphone battery, a new tool may help.
Called Hush, it automatically ‘kills’ the apps you rarely use so they don’t carry out any activity in the background, draining battery out of sight.
The researchers claim the Android software can reduce the total daily energy drain by 16 per percent, and extend battery life by a sixth.
A tool called Hush automatically stops apps you rarely use so they don’t carry on running in the background, draining battery in the process. A stock image showing a range of popular apps is shown
It is estimated 46 per cent of battery drain happens while a phone is ‘sleeping’ and 29 per cent of this is due to apps ‘waking up’ and running in the background.
To solve this problem, computer scientists at Purdue University in Indiana, together with Intel and a start-up called Mobile Enerlytics, developed Hush.
Android phone users can download the software now from Github but will need a certain level of technical expertise to follow the steps and install it.
Hush’s creators have said, however, that they intend to turn it into an app.

Hush works by detecting frequently used apps and stopping the background activity of other rarely used apps.
The researchers claim the software for Android phones can reduce the total daily energy drain by 16 per per cent and extend battery life by one-sixth, meaning users will have to plug in their mobiles less frequently
‘They are not letting the phone go back to sleep because of software bugs and, specifically, due to the incorrect use of Android power control application programming interfaces called wakelocks.’
The team revealed the tool at the Association for Computing Machinery (ACM) MobiCom 2015 conference in Paris.
While developing the tool the team found that when a phone’s screen is off, a device continues draining power for various legitimate maintenance purposes such as its Wi-Fi system sending a periodic signal to the access point once every 200 milliseconds and a ‘cellular paging’ function, when the phone talks to the base station every 1.28 seconds to check for incoming calls or data.
They will now look at ways to cut down battery usages even further and Professor Hu’s ultimate aim is to double battery life for smartphones by refining the tool.
