apple made significant improvements to the battery life of its iphone 6 and 6 plus, but they still fail to last more than a full day with typical usage to address these issues, the tech giant is recruiting for battery and power software experts at least nine job listings have been spotted on the firm's official recruitment site as the company looks to boost the battery across its range of mobiles and laptops fan site appleinsider has spotted nine job listings on apple's official recruitment site in the past month that relate to batteries these include one for an ios battery life software engineer (pictured left) and another for ios software power systems engineer (pictured right) the job listings were discovered by fan site appleinsider and include listings for an ios battery life software engineer, a software power systems engineer, battery pack engineering manager and a cell engineer in particular, the ios software power systems engineer role said the successful candidate 'will be working on design and development of software for triage of battery life issues, modeling of power consumed by different parts of the system, and analytics to understand large scale battery life trends' apple defines the apple watch battery on its watch product page it says its all day battery life is based on 18 hours of use all day battery life: this includes 90 time checks, 90 notifications, 45 minutes of app use, and a 30 minute workout with music audio playback: the battery will last up to 65 hours when playing music talk time: apple said the watch can be used for up to three hours for calls workout: during this test the watch lasted for seven hours when a workout session was active and the heart rate sensor was on watch: when used as a watch the device will last for 48 hours if checked five times an hour power reserve: when the apple watch's battery  gets low it switches into power reserve mode letting users tell the time for up to 72 hours   with four time checks an hour charging time: the company said it takes 15 hours to charge the watch to 80% and 25 hours for a full charge apple's tests were carried out in march 2015 with a pre production apple watch and software paired with an iphone using pre production software apple said battery life varies with environmental factors, use, configuration, and 'many other factors' so actual results will vary  as the site suggests, this shows apple is looking to boost the battery on ios devices but also its range of macbooks apple's larger iphone 6 and 6 plus have been found to last about eight hours with heavy usage and up to 22 hours with normal usage   although its difficult to quantify what 'normal usage' is and this can differ from person to person these times have only been beaten by samsung's latest galaxy s6 apple also said its new 12 inch macbook uses 30 per cent less energy than the previous model and could last more than nine hours on a single charge however, official figures suggest its watch in particular will struggle to last for anywhere near that long boss tim cook said at the launch event last month that the watch will last 18 hours, but this only includes 90 time checks, 90 notifications, 45 minutes of app use, and a 30 minute workout with music apple is expected to launch an iphone 6s, 6s plus as well as potentially a four inch model later this year battery improvements could be made to these handsets, or they may be a feature on next year's iphone 7 alternatively, because a number of the jobs refer to a software rather than hardware engineer, these battery improvements could be made and rolled out to existing phones as part of an ios upgrade earlier this week atmel released its latest  microcontrollers (mcus) for a variety of gadgets that are so low power they can harvest energy from a person's body the  sam l microcontrollers are part of atmel's 32 bit arm based mcu range and are powered by chip maker arm's cortex m0+ 32 bit processors a number of apple devices, including the iphone 5s and ipad air are powered by chips based around arm technology atmel said its mcus extend 'battery life from years to decades, reducing the number of times batteries need to be changed in devices such as fire alarms, healthcare, medical, wearable, and devices placed in rural, agriculture, offshore and other remote areas' apple's iphone 6 and 6 plus have been found to last about eight hours with heavy usage and up to 22 hours with normal usage   although its difficult to quantify what 'normal usage' is and this can differ from person to person apple also said its new 12 inch macbook (pictured) uses 30% less energy than previous models  apple boss tim cook said the watch's 'all day' battery life lasts 18 hours with 'typical use'   but official tests recently revealed this equates to just 90 time checks, 90 notifications, 45 minutes of app use, and a 30 minute workout with music apple defines the battery on its watch page and said a time check  lasts four seconds  they use a third of the power of rival chips and tests have shown they are the lowest power microprocessor ever made the microcontrollers run on the firm's picopower technology and atmel's event system that makes different parts of the device work together to carry out tasks by effectively 'sharing' energy, the whole device uses less power and, subsequently, less battery it can also manage how much energy is being used by other components to make them as efficient as possible plus, the technology is so low power it can harvest energy from the body using changes in temperature earlier this week atmel released its latest microcontrollers (mcus) for a variety of gadgets that are so low power they can even harvest energy from a person's body atmel said its mcus extend 'battery life from years to decades, reducing the number of times batteries need to be changed in devices' during a demonstration of the microcontrollers at this year's ces, andreas eieland, atmel's director of product marketing demonstrated how he could power a radio by placing his hand on a panel this panel recognised a change in temperature between the hand and the room and this was harvested to create charge
