Battery Life

I've had the phone since Sept 6th and this is 4th day I have my phone.
My battery life has been draining like crazy. I don't have a data plan, but I do go on wifi sometimes (not very often, and I don't keep it on for long). Maybe in total an hour to two a day.
I wouldn't say I am a heavy user, I don't play any games or watch any videos nor listen to music at all. I only sms and download apps.
It's been 5h 42m 35s since unplugged and my battery life is down to 57. I hardly use it, my settings are pretty much the lowest.
It says
Android System 40%
Cell standby 21%
Phone idle 13%
Display 12% (weird, since I have animations are turned off and I used lowest brightness)
Camera 6% (I took 3 photos)
Wifi 4%
Maps 2%
Dialer 2%
about 2 hours ago, I rooted my desire since I've read reviews that it makes it faster, prolongs battery life and what not. (plus I could do so much more with it later on). But my battery was still draining at like 1% every minute and half that I touch it. (I also have task killer, but I don't kill task very often)
Then my friend suggested I get SetCPU (which I did) around 2 hours ago after I rooted my phone. Then I went out and hardly touched the phone unless I received sms, or to check the time. And it went from like 69 to 56 (within that 2 hours of doing nothing)
I've searched the forum for extending battery life (and googled as well) and read other users who have the same problem, and I pretty much did what was recommended but it's still draining.
I can hardly make it through the day!!
Is there any other way that I can charge it (when to charge it) or.. do you think it might be my battery's problem? Should I buy a new one?
Thanks for all the help again (I know this kind of thread has already been done, but that was in like April)

Your battery takes time to settle if it's a brand new device. It takes a few charge/discharge cycles for that.
If after say 14 days you are still getting poor life I'd try calibrating it. Instructions are HERE.

thanks! i will try that if my battery life still drains this crazily in a week.

Cell standby

I've been better monitoring my batterylife today to see if I can get by on a normal work day or if I'll need an exteded battery (ever since getting the phone its been dying very quickly, because I've been playing games on it). So far, it's been going all day and will definetly reach the 10 hour mark with web browsing and texting. However I do 1 concern, 30% of my battery life has been used up by 'Cell Standby'. Is this normal? I had an extended battery on my g1, so I never had to worry about battery life too much, and don't know how much cell standby took up on it. I'm just suprised that it takes up more than "android System" or anything else on my phone.

Update- just to give you a grasp of my battery usage for the day:
was not put in charger all day
currently at 10%
been on for 13h and 56m

cell stanby 31%

[Q] Battery Life Issue

I am having battery drainage due to the display (unlike most people who are having battery issues because of the android system). I've tried dimming down the brightness and putting the screen timeout to the lowest possible but the display still sucks up most of my battery. Can anyone help me with this ?

I think that would be normal. It's a 4.5 inch touch screen; it takes a lot of juice to be so pretty ...
Under settings - about phone - battery usage - display, what is the time on vs. % of battery usage?
I've been off the charger for 30 minutes and display use is at 76% since I've been browsing news and xda non stop.
If your screen on time is low compared to it's battery usage, it's a different story. Sounds like you've tried the usual fixes.

Well I've been off the charger since 12 last night so it would be 12 hours. But the thing is that the display usage says 51% and the actual time on for display was only 2 hours.
and also my battery drains 1% about every 30 minutes with the screen off.

2 hours of screen on time sucking 51% of the battery sounds normal to me, even across other Android phones on GB. Touch screens use lots of power.
Maybe someone else can chime in with something I'm not getting, but it seems normal to me.

This is a screenshot of my E4GT after 33 hours off the charger with normal usage. I don't play games, but I do text a lot and had a few calls as well. As you can see, the screen was on 20% of the 33 hours, meaning 6.6 hours etc etc and I still had 9% battery life at that point.
I am loving my phone!

Doesn't that 20% mean that the display used 20% of the battery power, not that it was on for 20% of the time? If you select the Display, it actually shows you how long it's been on.

I just feel like my battery should last longer than it does. I used to own the moment and that would last me three days with moderate use. ButI guess that this phone is more powerful it would make sense not to last three days. If only that would happen haha

[Q] Fast Battery Drain?

Hi,
Yesterday I was on my Xperia Play - because we were on a day out.
However, and the my surprise, we weren't even halfway there (to the destination which was a 1 hour journey) where my battery went from 100% to around 40% with only occasionally use and using my data. Then, once I was there, my battery (without even using it!) went from 40% to around 20%. Once I finally got home, using things like turning off WIFI and data, lowing the screen brightness and turning off GPS - I only had 4% battery left!
Is it normal for my battery to only last 10 hours - even though I'm not a heavy user!
(My friend's iPhone still had around 60% after doing the same things I did!)

My battery on the xperia play lasts about 5 hours with heavy usage. There is another thread in this forum where people talk about the kind of battery life they get. You can go there to see what kind of battery life others have.

[Q] Plz Help!! Battery issue (fixed for now)

I bought G Pro day before yesterday. The device is amazing and i love it but i have got a small problem. First day i charged battery to 100% and i got a day usage with 25% of brightness set with screen on time for about a little less than 4 hours which is amazing. Yesterday i had to charge phone twice because the battery depleted within 2 hours on screen time and moderate usage like calls n text (no gaming). Today morning 80% power was left of second charge. I went to college and and did not use the phone much but battery got completely depleted within 1 hour of screen on time at 50% brightness. When i came home back i charged the phone to 100%, when i disconnected charger from phone the charge dropped immediately to 98%. After 3 mins it fell to 93% and now is depleting fast. there is no apps running in background or anything and no apps showing up in battery stats that may be depleting battery. Any solutions to this? can it be faulty battery? Plz Help!!!
Edited: viber or whatsapp was causing this battery drain. I rooted my phone n installed greenify. Hibernating all user apps fixed the battery drain. If anyone has battery drain issue may try this solution.
