Galaxy S4 vs iPhone 5S on Battery Life and Processing Speeds, See How Top 8 Smartphones Perform [PICTURE]

Apple 5S has passed performance tests as the high processor speeds, but battery life is left lacking compared to other smartphones. Clearly the Samsung Galaxy S4 has a bigger body so it leaves more room for battery size which helps. 

Research carried out by Which? magazine has compared the battery life of the Top 8 smartphones including Samsung, Apple, HTC, Nokia and BlackBerry phones in terms of call and web browsing time. 

Here is how the test worked: 

Each phone was tested using Which?'s'phone network simulator' in which each handset is placed on the same mobile network and tested in the same place. 

This means Which? could make sure the signalstrength was the same every time. Signal strength can impact battery life because phones in poor reception areas have to work harder to get a signal.

Which? also set the screen brightness on every phone to the same 'readable' level and not on maximum because Which? didn't want to 'penalise phones with brighter displays.' 

Each of the phone's batteries were 'conditioned' before testing, which means they were fully charged and discharged prior to the tests. 

During tests, principal researcher and writer at Which? magazine Jon Barrow made a continuous call, for the call time test, and regularly updated a specific web page over 3G, to test web browsing battery life. (via Dailymail.co.uk)

The tests prove that the batteries in the new iPhones last longer than those in the iPhone 5, but still aren't capacity of the best Android phones.

The iPhone 5C managed 564 minutes (9 hours and 24 minutes) of calls or 252 minutes (4 hours and 12 minutes) online. 

Meanwhile, the iPhone 5S ran out after 651 minutes (10 hours and 51 minutes) of calls or 298 minutes (4 hours and 58 minutes) browsing the web.

The processing speed tests came with these results, Apple's iPhone 5S was at the top of list, with the LG's G2 in second. Samsung's Galaxy S4 came third. iPhone 5S broke all records in the magazine's processor benchmarking tests which is very impressive.
