As far as we know, the Nokia N900‘s battery life is comparable shorter to other phones out in the market. But there are some few tips we could use to reduce the power consumption to the device.

1) Disable touchscreen vibration

Go under Settings > Display. The touchscreen vibration feedback is actually recorded as a process. So imagine clicking 100 times would record 100 times of processes. This would take up a lil by a lil of the power. Proof :

As you can see, the process is recorded as [vibra]

NOTE: Above process is detected using the command “top’ in X-Terminal

2) Decrease the brightness level

Decrease the bright to a suitable level but not set it too high. Simple logic, brighter lights = more power consumption

3) Usage of Apps

Apps we’re looking at: AutoDisconnect, BatteryEye

In AutoDisconnect, you would get to choose when to disconnect your Internet Connection, 3G and even Bluetooth automatically when not in used. This would save up alot of power in the long run.

In BatteryEye, as the app’s name says it, it graphs the power consumption in your phone. So you can check where you are losing most of your power and try to reduce on it by changing your personal usage habits.

4) For Advanced Users

Multiboot between separate kernel patches would be a good idea. As far as I know, there are 3 types of kernel available for the Nokia N900 Maemo patch. These are:

2.6.8-omap1 which is the stock kernel

2.6.8.10power46 which is the power kernel or known as Titan’s kernel

2.6.8.10power46wl1 which is the bleeding edge driver for wifi cracking kernel

The stock kernel manages power the best. So boot into separate kernels up to your own likings and usage. If it is normal daily usage, stock kernel would manage the device power the best.

So anyone with extra knowledge, tips and idea would be welcomed to post it in the comment section and I would update this post as it goes.
