Long live the N900 – a word on battery life

2 March 2010Entry by

While browsing the web I’ve seen some discussions on what the N900 actually is. Some say it’s ‘obviously’ a smartphone, pretty advanced, based on Linux, but still smartphone. On the other hand it may be considered very small computer with phone application and hardware. All of this opinions have one mutual concept: Nokia N900 is mobile device. If it is, battery life is one of the most significant characteristics that people pay attention to.

Doing nothing with mobile device is the best way to let the battery live longer but I don’t think any of us bought N900 to let it be in stand-by all the time. Some of applications or widgets drain battery more when working in the background, for example:

  • instant messengers – most of them remain constantly connected to the internet, sending and receiving data and using CPU, so having many accounts connected al the time will drain battery faster
  • frequently updated widgets - similary to messengers if you have lots of widgets using your internet connection
  • bright screen backlight – more light is more battery drained
  • applications running in the background – some of those applications may use your processor and subsequently baterry
  • frequent e-mail accounts synchronization – especially the exchange account may cause battery drain if synchronized to often because it causes significant CPU load

So how to make your battery last longer? Let’s try few simple things:

  • lower screen brightness and backlight time, turn on energy saving and turn off screen vibrations (Settings, Screen)
  • swich IM status to offline when you don’t need to use it
  • change synchronization interval of your mail accounts to longer
  • prevent using frequently updated widgets, if you have the possibility change update interval to bigger or to update on demand or homescreen switch (like in Personal Dataplan Monitor widget)
  • turn off Bluetooth if you don’t use it (I find it also safer to remain hidden)
  • close application if you don’t need to use it for some time

If you need to check what is the best for you, try some of options and use battery-eye or BatteryGraph application to compare energy usage on your N900. As for me it works quite well, sometimes I hit over 2 days with such precautions, try yourself.
