With battery life still topping the list of most people ’ s smartphone wishlists , a London-based manufacturer has launched a handset with exactly this in mind . Kazam ’ s latest flagship , the Tornado 552L , has an ‘ extreme ’ power save mode that can extend battery life for up to a staggering 33 hours . When the battery reaches 10 per cent the power save mode kicks in and turns the whole screen black and white . Kazam ’ s Tornado 552L ( pictured ) has an ‘ extreme ’ power save mode that can extend battery life for up to a staggering 33 hours . When the battery reaches 10 per cent the power save mode kicks in . It also shuts down or manages certain services and apps to save as much energy as possible . This 33-hour figure is the absolute maximum and only applies when the phone is on standby . The total battery life on standby is almost two days or 45 hours approximately . Frame : Metal U-shaped skeleton measuring 5.5mm thick . Processor : 1.7Ghz octa-core processor . Screen : 5.2-inch capacitive touchscreen . Cameras : 13MP main camera and 8MP front camera with Magic Focus and LED flash . Battery : 45 hours on standby plus extreme power save mode . Software : Android 5.0 Lollipop . Extras : Kazam ’ s cracked screen replacement , Rescue package and three-year warranty as standard . Price : To be announced , but should be in the region of £290 ( €400 ) As with any battery life , the length of time will drop depending on how much it is being used . These are bold claims , however , and MailOnline will be putting the phone and its battery life to the test later this month . Other features on the flagship phone including a 5.2-inch touchscreen . The Tornado 552L runs the latest Android software 5.0 Lollipop , without a skin , and has a 13MP rear-facing and 8MP front-facing camera . Sleek : Other features on the flagship phone including a 5.2-inch touchscreen . It runs on a 1.7Ghz octa-core processor and is super slim at 5.5mm . It is part of the same Kazam range that includes the world ’ s thinnest handset , the Tornado 348 at 5.15mm . And to make the phone stronger , Kazam told MailOnline the phone has a unique so-called ‘ U-shaped ’ skeleton , or frame , designed to withstand knocks and drops better than other models . Elsewhere , the 552L comes with customisable gesture controls . For example , drawing a C in front of the phone ’ s screen opens the camera while drawing an M plays music . These are the stock gestures , but a range of shapes including V , W , S and Z as well as two-finger swipes up , down , left and right can be tailored to whatever function the user needs . Plus all Kazam phones offer free cracked screen replacements for the first year , a Rescue service that gives users direct access to technical support and three-year warranties as standard . The handset will be available across Europe but prices and availability haven ’ t been announced . As a guide , the Tornado 348 starts at £249 ( 342 Euros ) and the 552L is expected to be in the region of £290 ( 400 Euros ) . The official price will be announced nearer the time of launch later this year . ‘ MWC 2015 is a huge show for Kazam and the launch of the Tornado 552L shows our commitment to delivering a top of the range phone at an attractive price point , ’ said Kazam boss Michael Coombes . ‘ This phone combines distinctive , super slim design with super fast processing speeds , an incredible camera and all the unique Kazam service offerings including cracked screen replacement , Kazam Rescue and three-year warranty. ’ At the event Kazam also unveiled a 4.5-inch Trooper 445L , three tablets running Windows 8.1 - called L10 , L8 and L7 - and a feature phone called the Life C6 .
Kazam launched the Tornado 552L at Mobile World Congress in Barcelona . It has a 5.2-inch screen , 8MP rear and 13MP front-facing cameras . Extreme power save mode is enabled when battery reaches 10 % . Firm claims it will then last for 33 hours on standby . This time is a maximum and will be lower if the phone is used extensively , plus time depends on usage . Other features include customisable hand and finger gestures .
