Battery life has become a nagging headache for the majority of today’s touchscreen smartphones. Those displays with the fancy user interfaces that require high-clock CPUs simply guzzle humongous amounts of power. In many cases, the batteries do not last through a day of heavy use.
I have had the X10 Mini Pro for a couple of months now. As a rule, it gets me through a day of intensive use. By intensive use, I mean that the Mini Pro is automatically syncing with Gmail, Google contacts and Google calendar on a 3G connection, making and receiving calls, sending and receiving SMS, and being used for Facebook and web browsing.
By way of comparison, for example, I had to set the Nokia N900 to connect to my mail server once every 2 hours in order to get the battery to last me till 5 p.m. If set the mail client to a sync time of 5 minutes, the N900’s battery gives up in a few hours.
I ran an extreme battery test on the X10 Mini Pro to see how much to expect of it in a worst case scenario. In this test, here are the parametres that I set up:
- I charged the battery full
- Set network mode to always-on 3G
- switched WiFi radio on
- switched Bluetooth on
- set volume to loudest
- set Gmail synchronisation to automatic, so delivering always-on real-time email
- set the display backlight to brightest
- watched a movie for about 20 minutes
- played some music for about 10 minutes
- automatic synchronisation with Google calendar and contacts
During the period of the test, I received 2 SMS conversations and had three phone calls of a little over 4 minutes. I also browsed the web for 1 hour.
The test commenced at 7.25 p.m. About nine hours and twenty minutes later, the X10 Mini pro shut down at 4.43 a.m. That kind of result in an extreme situation suggests that my regular experience of having the battery last a day or more is just fine.
The X10 Mini Pro’s battery life is very much comparable to the Touch Pro2’s. Certainly much, much better than what the N900 delivers.
