Ok lets do facts checking one by one here since i m being ignorant here and with the spirit of posting only correct info to help visitor to this thread.

1. To lengthen battery life span, avoid/minimize full charge
- You can't full charge li-ion batteries, your 100% on screen is not actual 100% charged. Modern batteries have a built in mechanism to cut off when this threshold is reached.

2. To lengthen battery life span, avoid/minimize full drain.
- Again, you cant fully drain to 0% in all ori battery, there is a cut off reserve to avoid permanent damage to li-ion

3. Preferable, use your phone until battery dropped to 5-10%, then charge up to 95%
- Lithium ion chemistry prefers partial, bite-size discharge to big discharge, say 5% to 95% in your example. Your battery can have longer life if you charge it often rather than charging it in one full charge.

4. Full charge/ full drain will exhaust the battery even quicker.
- You can't. Refer 1 and 2.

Anyway, the misconceptions on battery charging happened when we read sites with lab information on battery charging best practices than the actual current advances in battery manufacturing processes in the industry.

Mind to share how to do?
I am net resting to addd few app to multi windows

You need to root your phone first.

Sure root after out of box

1. like fruitie said, u need root
2. make the zip file here. read carefully from the instruction http://www.modaco.com/topic/358494-lj1-not...ti-window-tool/
3. click "build me the zip" & download & transfer the zip file into ur sdcard
4. boot to recovery
5. flash the zip.
6. reboot
7. open the multi window blue thinggy, click edit. the apps u just flash will be there


( i only tried 2 apps, so dont know how safe it is ) but, u can add multiple line from the modaco site.

example : <item>put.packagename.here(1)</item>
<item>put.packagename.here(2)</item>

decide to pass the note2 for my wife.... only keep note1 and use back nexus... later will start waiting game again for nexus 4... bye bye n2 :_(

Interested in battery issues. Read this guide

http://batteryuniversity.com/learn/article...based_batteries

u r running LJ3 or LJ7 rom ?

Table 2: Cycle life as a function of
depth of discharge

A partial discharge reduces stress and prolongs battery life. Elevated temperature and high currents also affect cycle life.


last time when i think to makes to battery more long alsting...i reduce the charging time and wait until it drop to critical level on charge... but seems this is the wrong way...

I'm loving my phone so much. Aargh. It is so brilliant.

"Avoid charging a battery faster than 1C; a more moderate charge rate of 0.7C is preferred. Manufacturers of electric powertrains are concerned about super-fast charging of 20 minutes and less. Similarly, harsh discharges should be avoided as also this also adds to battery stress. Read more about Charging Lithium-ion and Ultra-fast Chargers."



i still remember that sony phone highlight on their product that they can super fast charge the xperia p from 0 -60% in 20 min times using their original charger.... wondering is that 1 of the reason xperia p battery not lasting...

LJ3. Im on stock rom

glad u happy with it... i am passing my 3nd wife (note2, 2nd wife is my car) to my wife....

Same here, the more u use, the more u like, my iphone just put aside lol, the screen is big and nice, just the colour is not as good as retina display that I have to admit, amoled stil behind retina display

For the paranoid or statistically inclined:

More concerning is that many apps collect information or require permissions unnecessary for the described functionality of the apps. This is not the first time this issue has surfaced – reports of popular apps collecting irrelevant information or transmitting data when devices are turned off has led to significant backlash. However, less is known about the state of privacy across the entire application ecosystem.

To get a sense of the state of application privacy today, Juniper Networks’ Mobile Threat Center (MTC) analyzed over 1.7 million apps on the Google Play market from March 2011 to September 2012.

......
Accept some exposure with free apps. It seems there is no such thing as a free lunch in mobile. If people choose to use free applications, they will likely need to provide information in exchange. Often times, the value provided by the app is well worth the information given up by a user; however, many do not realize that this tracking is happening and may not be making informed choices. Communicating why information is needed in a concise and easy-to-understand means could help people become more comfortable with information sharing.
......

So, CHECK APP PERMISSIONS BEFORE INSTALL.

Here is my battery life today, on 3g all the way, not sure good lol

Addictive..??

My english is bad, so i don't make myself clear i guess... my points is avoid/minimize 1. full discharge; 2. full charge. but yes, you can charge it often, from 20-50%, from 5-80%, from 50-90%, no issues, and i agree often charge is better for Lithium ion battery (LIB)

just a head up by the way.. lengthen battery life-span is more important than worrying how many hours your battery can lasts a day.

EDIT: correction on my terms. what i mean by "full charge" was actually "overcharged". like you leave your device charging overnight. if your battery is working good, supposedly it will stop charging when its "full".. but, again, prevention. prolong charging will also induce heat, which may lead to cell rupture.

Aiyo bro, i didn't invent the cut off mechanism la, its been an industry standard for almost a decade already...if its not reliable, Apple/HP/SONY had probably kena gazillions of lawsuits on battery already.

And of course a battery can full discharge and dies one day if leave on table untouched for a month...unless it is a macbook air. You are missing on the context on what we are discussing. We are talking about day to day charging practice of the phone, not talking about leaving the phone discharge while you go holiday for a month. Thats why every manual you read says keep 50% charge if you battery not used for long period of time. But what im saying is that the battery will not fully discharge until unusable within your normal day to day use, otherwise you wont be using the phone.

I signed up for maxis plan on sunday...
RM30 (Calls) + RM68 (3GB Data package) + Galaxy Note 2 for RM1799.
Today there's a new package...
RM75 (5GB data package) + calls depending on how much u use.
Is it possible for me to change to it?
