Yes I tried it on my other N900. It is a "nice-to-have" but not really a "must-have".

ah ok. tumatagal naman po ba yung batt life using those 2 sir? or any suggestions po kung pano mapatagal batt life ng n900?

install wifi switcher. This will turn off the wifi from scanning which drains a lot of battery life.

install auto disconnect. Will automatically disconnect any connections.

install the 2g/3g switcher. Some area doesn't have 3g connection so it will try to search 3g which it will drain battery. So it will save more battery life when its in 2g.

Friend,

I don't think any application is designed to help prolong the battery life of a device. There are applications which help you save battery but by themselves, they don't really save battery. In short, these are just applications that automate stuff that you need to do to save battery life (such as Wifi Switcher, Brightness App, etc.).

By the way, I noticed you've been asking this question from the start as well as in other forums...you need to understand that the N900 is a Mobile Internet Device (a tablet) with phone features...it is not just a smart phone but instead it is like a mobile computer (like a netbook/notebook). With this, you need to set the expectation that the battery life of the N900 is not like the regular smart phones (which last at an average of 3-4 days with normal use).

On regular to strong usage, the N900's battery consumption will give you somewhere between 4-6 hours max and that's it. On minimal usage it can extend to probably 12 hours or so. Instead of comparing it to smart phones and thereby feel disappointed, why don't you compare it with regular laptops (notebook/netbook) or similar devices? (the N900 is a tablet anyway) Laptops using regular batteries last for only 2-4 hours or 6-8 hours using extended batteries. The N900 lasts for 4-6 (strong usage).

If you really need that much of "battery life", then the best suggestion for your situation is to either buy an extra battery or always bring a charger.

nowadays, what we call phones are not just only phones, there are so many features that we can make more than just call or send SMS that contributes to additional battery drain. If you have had a Nokia 3310 (who didnt?), i can say that mine lasts over 4 days normal, and 2 days with playing snake and space impact 2. but with phones today, more games, features and stuff......that you're not realizing using its non-telephony functions more.

ako i understand why my battery drainn fast using alot of apps that drain battery

pero sabi nga nila nokia n900 is not just smartphone its computer

ako nga naka OC pa before i use 1.1ghz that drian my battery fast i even use all the 4 windows kaya ang bilis sobrang ma drain now i OC in 900z na lang battery last long now battery drain

gusto ko lang magrant sa phone na ito dahil mga me ari lang din ng n900 ang makakaintindi:

wala talgang kwenta tong phone na ito. halos sang taon ko ng ginagmit at pinagsisisihan ko kung bakit ko binenta iphone 2g ko para lang makabili ng 27k nung unang labas, ngaun 2nd hand eh 10k n lang, napakabagal ng browser, nacorrupt n ilang beses ang conversations ko, naghahang at madalas kahit sariling recorded video eh unsupported daw. iniwanan pa ng nokia ang maemo. battery eh, pag dating ko bahay dapat magcharge, pagdating ng office kelngan ulit. sising sisi ako dito.

hinde porket ang daming apps eh rason para mubos ang battery kagad. nagcraxrash pa madalas ang mga application. hayyy

sir sorry to hear that pero sakin nabasa dito sa forum na eto ikaw pa lang ang nag sisi ng grabe sa phone na to

na try mo bang fix yung mga problema kung bakit ganon

sakin eto na ang phone na pinaka madaling ayusin kasi pwede mong flash pag nasira kuing babasahin mo yung post ni sir Topet2k12001 maiinitindihan mo kung bakit mabilis mag lowbat

pasensya na pero gusto ko lang talga umangal. me mga kakilala kong me n900 din though gamit nila sa phone na ito eh talk n text lang, kung baga eh nababaliwalang kwenta yung phone sa opinyon ko lang, kahit tatay ko gumaya n900 din at madalas kahit pag me nawalang shortcut o widget eh sakin lagi tatakbo

gusto ko to dahil sa multitasking, though madalas napakabagal ng phone lalo na pag me browser na nakabukas. yung sa conversations na biglang masisira napakasakit nun. maraming pwedeng gawin at lang kalikut na ginawa ko dito pero sa totoo lang mas marami pang sakit ng ulo at madalas napapahiya pa ko kahit magopen lang ng video o picture ang tagal.
