Please, let me know what should I do after installing better battery stats and SpyCPU. What options should I choose and what to do next to discover what is causing my battery drain.
This is where the reading part comes in...

I'm afraid there are no short cuts... it's a case of sitting down with a beverage of your choice and reading since everything you need to know about optimising the battery life of your phone, is there.
No one can say to you that you must delete this, or keep this... because everyone uses their phone differently. Only you can decide!
Those sites are the best places to look for answers and pose questions. At the end of it, you will be as knowledgeable as some of the other guys on here.
You can also start by getting rid of, "
bloatware", if you haven't already.
Is there a way to turn off wifi / data automatically when your phone is in stand by and letting it check for mails without using juice defender or any software like it?
I don't bother as my phone is now optimised and it would use more battery to monitor and turn them on and off, than I would save.

There are basically 2 areas to focus your attentions to on battery life.
1. For when your screen is on
2. When your screen is off.
Obvious eh? But just think about this for just a second...
* The screen is THE biggest battery drainer there is. Full stop. Its one of the pitfalls of having such a good one!
* The most used state of your phone is when its on idle.
Therefore, if you can make inroads into improving the efficiency of your phone in one or ideally both of these states, then you will be enjoying your phone for much longer periods between charges.
Therefore, you could start by doing the following...
At bedtime tonight, just before going to sleep, take a screenshot of your HOME screen, providing this shows the time and battery %.
Then go to CPU Spy > Menu > Reset Timers.
Then BetterBatteryStats > Menu > More > Set Custom Ref.
Go back to your HOME screen and do not touch your phone until the following morning. After your 3rd coffee, in my case, wake your phone up and take the following screenshots..
Home screen
CPU Spy screen
BBS screens, after setting the 2nd option on the screen to, "Since Custom Ref.", take a screenshot of all states, i.e. Other, Kernel Wakelock, etc; etc:
You will now be able to compare your 2 HOME screen shots and see how long your phone has been asleep/idle and how much battery it used in that time.For example... if your phone was asleep for 8 hours and your battery dropped by 12% then you average battery usage is..
12 / 8 = 1.5 Therefore your battery drop is 1.5% per hour.
You can then refer to your CPU Spy and see how much Deep Sleep % you had. In other words, how much your phone was awake.
You then look through your BBS screenshots and find out what was keeping your phone awake. Do this every night and you're halfway to solving your battery problems.
as I said in my previous post..."
it has taken me months of trial and testing to achieve my battery performance and it is still ongoing."
(I suggest that you start a new post rather than clog up the NEAT thread as this is not directly related exclusively to NEAT)
