Do I need a Battery saver?

[#1]

I follow these steps regularly..

I always keep my brightness to level 0 whenever i need i increase it by 40%

I always keep my GPS,WiFi,DataConn. & Background Sync. is in off - when ever I need enable them

Most of the time I use the GSM only as prefered network mode... when ever I connect mobile Data Conn. I switch to WCDMA(prefered)/GSM mode.

once I finish browsing I revert it to GSM mode.

frequently check my running services & stop them which I unwanted settings-->applications-->running services

So do I need to install Battery saver (ex juice defender)?

I installed macafee security... it seems to be use more battery when i check "battery use" menu

is there any way to reduce it... or does this app really need?

if your battery last 10-12hours thats normal. juice defenders, taskillers, anti virus are really bad, they drain a lot of battery and slow down your phone

charge your phone 100% then use it normal, once you get to 10% go to

settings -> about phone -> battery use take screenshots and post them here also tap on each one and take screenshots

Do not charge the phone inbetween

today morning at 6 -100%

I didn't follow any of steps which i mentioned early.

once i remove from charger i do the following.

brightness - 25% 

Data conn - ON

network mode -WCDMA(prefered)/GSM

background sync - ON

GPS - OFF

WiFi - OFF

Today I browse little more when compare to other days (FB,Gtalk,Market)

suprisingly I didn't c any Macafee security... 2 days b4 it sucks more battery then display

that looks like a normal battery use, screen will be #1, 12hrs seems about right. don't use any of those battery/juice defenders, that's my suggestion

Thks Dude.....

                          If I maintain the battery level between 30-80%

is it increase the battery life?

[Uliwooly]

30-100% it's fine, you are asking because of that article that was released right?

but one thing that has a big impact to li-ion batteries is heat, so don't keep your phone close to really hot things or during summer direct sunlight, just a suggestion

Guys.. Thanks for all your responses....

I didn't ON bravia engine & hepatic...

More over I always in roaming circle, I didn't change my location... but this happens from last night..

my standby & idle sucks battery very much... ( changed from 5%(usual)  to 30% (last night))...

Take a look at this screen shot... within 3 hrs it drains 22% ....

I used FB ,YouTube for 10 min,3-4 min of call.

Plz tel me what's the gray area & green area in phone signal column in that graph....

I see an icon on the top left side, from which app is that? was the screen ON the whole time your fine was supposed to be on Idle? make sure to include how many hrs/mins the screen as on and the other top items.

but as you can see, your phone its constantly looking for a signal, thus, draining your battery
