Alright so, i grew tired of this, i literally tried everything, changed kernal used [Phenomenal Extreme, Siyah undervolted and battery friendly governer and i/o.. other kernals also]
Fast democracy disabled, GPS disabled, Wifi disabled, 2G Network, Auto brightness, disabled heptick feedback... other things i cant remember
Tried different ROMS with different base(AOKP, Samsung based)
Undervolting and underclocking, also tried different modems.
And still my battery can't last 24 Hours with soft use, 2 - 3 maximum display time, also i guess deep sleep is working perfectly with SOME wakelocks, when the mobile is on 100% battery, it remains that for 6 - 7 hours if it went to deep sleep, the problem is when it drop below 100% it starts to drop fast, today i went out to my college with 84% went back after 6 hours with 66% left, with really soft use, just 10 min gaming and 2 phone calls, thats a huge drain for a deep sleep.
Ill leave you with the screen shots.
Your battery usage looks normal, you just seem to be expecting too much.

You think? Does you battery last more than 20 hour with 2 hours screen on?
seems normal to me...
How your telco signal??great or bad??
seeing the pics well its normal,the only thing wiv power comsuming is audio so ill say turn off audible touch tone,selection,lock sound,heptic feedback...and sometimes batterys die soon ,i mean they don deliver the power they must....

This is not always true. It all depends if your network supports fast dormancy.
In my case, fast dormancy enabled enhances my battery life very much because my network supports it.
To check if your network supports fast dormancy do the following:
dial *#0011#
look at your RRC STATE
If your rrc state reaches IDLE after a few seconds then your network supports fast dormancy.
In that case fast dormancy should be enabled in order to benefit from it and help you save more battery.
I hope this helps.

Hi Everyone,
I am disappointed with the battery of Optimus One.
My Battery in Standby (GPS/Wi-fi/3g/Sync/Screen, ALL OFF and without USE ), does not last even 20 hours.
I have an application that shows what application is consuming more battery power and the "phone in standby mode" takes up 95%!
What are your experiences with this battery?
Mine has problems?
Thx
I bought it one week ago and the battery last one day with no problem (and it's not at its full "potential" since is new). When did you buy the phone?
I bought it 2 weeks ago
Using a custom rom you won't be disappointed with your battery no more...
I have openOptimus Rom with Franco kernel 15. I am at 85% battery after 14 hours. The phone has been pretty much idle.
Only 2G networks
Data disabled
Wi-fi on
Auto-sync on
Overclocked 480/729 interactive (interactive may not be optimal)
I'm using franco kernel v15.1 with devoid.franco, i'll try do update do devoid.froyo.final today.

Hi, what is data disabled? and how to put only 2g networks?
20 hours on idling? Send it back for repair/replace. Mine will last days if left idling (about 1% every two hours)
When I travel I turn all data connections off (Bluetooth, wifi, gps, data) and it lasts about 3days

Here are some potential things to turn off that might make the battery last longer. They are all in the settings app. I do not do all these since I find that some things might make the battery last longer but reduce the usefulness of the phone.
Setting/Display/Brightness
Setting/wireless & networks/wi-fi off
Setting/wireless & networks/bluetooth off*
Setting/wireless & networks/mobile networks/use only 2G networks*
Setting/wireless & networks/mobile networks/data enabled off* (I have this turned off all the time as I do not have a data plan.)
The items * I have off unless I am actively using them. I also overclock my Optimus. I think that this probably gives me a longer battery life, since it is running at 480 when I am not using it. I suppose if I was desperate, I would undercloack the phone (min 480 and max 480).
What version of Android are you running? 2.2 or 2.2.1/2.2.2?
When you click on Cell Standby, how much Time Without Signal does it show?
follow these steps and i think ull have what you want..
go to battery use and click on cell standby : then see time without signal. how much does it show ? if its above even one percent (unless uve mannually put ur device in airplane mode) i know the problem.
go to settings >wireless & network settings > mobile network > mark 2G only (if u are not using 3G) cause the cell might spen loads of battery searching for 3G.. then go to network operators and search for (mannually) and select ur own network provider.. like mine is airtel.. then let your battery run down totally.. completly to zero. then recharge your phone to full without any break.. this is called recaliberation. then see how much your battery lasts..
remember to turn off bletooth, wifi, internet, all ! while the phone is idle and you wont be using it for sometime. or, if you wont be doing or getting any calls or sms, consider switching to airplane mode..
you might be getting less battery if ur in a area with weak signal strength.. this makes the phone go wilder to search for signal. in these conditions, switch to airplane mode if you can . thatll save a lot of battery. and also during night if you want to.
dont hesitate to click the thanx if i helped !
EDIT: and ya every thing that the person after me 'Y.u.v.i' said.. though those are normal things and brightness level is most important..
and about francos kernel, ive had many f/c s with mik's cm7 beta 6.2.5 ..i prefer its own kernel , though dunno for other roms.. u might wanna try it.. ill try myself too..
yes ..few step here u can try
1.reduce ur brightness level to minimum ...
2. use 2g signal only.
3. turn off all extra connection like wi-fi , Bluetooth, auto sync , data.
4. use advance task killer and set it to auto kill app aftr every 30 mints.
5.automatic screen time to 30 sec.
6.if u r using custom ROM use Franco 15.1 kernal . and wipe battery after charging it up-to 100%
use thanks if u like my post ...
I did all the tips posted here. Let us now see what happens

I'm using 2.2
7% without signal.
Sorry for the dumb question (about 2.2 or 2.2.x) - I didn't read the first page carefully enough.
Try this: reboot, then enable airplane mode, lock your screen and leave it like that for about a minute, unlock screen, disable airplane mode.
Are you still seeing Time Without Signal? (of course, after a few hours, not straight away)
EDIT:
DON'T do any of the following:
- reduce brightness to 1%... come on, be serious! you really like squinting at the screen? screen brightness doesn't affect battery life that much anyway...
- don't use task killers! it doesn't matter if you have little RAM - it's there to be used. I will not go into details about this (there's whole threads about it), but trust me!
You could also try monitoring your apps with https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result and see if any of them start behaving wildly and keep your CPU awake.
Another thing would be to try Nessy Hypnos2... I had great battery life when using that ROM! If you're still experiencing the same battery drain with a fresh install of Hypnos, then I'm sorry to tell you but you'll probably have to send your phone for repairs.
I ended up recharging the phone two hours ago and it is at 91%.
Was 9% in 2 Hours - 4,5% per Hour. Very Bad...
...with nothing in use.
Only 2g networks
wi-fi/dates/sync/bluetooth ( ALL OFF )
Screen OFF (black, with -0% of brigth, because he is OFF)
I install Battery Monitor Widget that estimates my uses of battery in:
18h52m of Discharge (100->0%)
and 5h of charg in USB and 3h of charge inc AC.
I'm installing watchdog now, to see if have an App draining battery.
EDIT:
But I do not think that's because I have an application that shows the the CPU clock in%.
480MHz = 80%
729Mh = 20% or less
and another that shows the applications that consume battery
and Cell Standby = 90%

I got the same. My phone is also on the same settings, same rom, same kernel. Battery life was awesome some days ago, but now I experience average battery drain, I think I need to callibrate my phone as well. :/ I will do it probably after flashing void.final.
Hi all, after a lots of pots from a lots of users claiming their battery is great or their battery is ok and even that their battery is a crap... I decided to open this thread to share my opinion with you all and see how many of you think like me.
Here it comes:
For me, BATTERY LIFE is how GOOD-OK-BAD our battery behaves and how much it lasts WHILE USING THE PHONE.
Having looooong periods of deep sleep is just the Stand-By 640hrs that Samsung itself offers with its ACE.
Under heavy use, ACE is supposed to last at least 11hrs using 2g and 6hrs using 3g.
Me just quoting Samsung and GSM ARENA
Click to expand...
Click to collapse
If you do the math, most of the people that claim to have a HUGE battery life have their phones on DEEP SLEEP (Stand By) MOST OF THE TIME, plus they don't use 3g but WI-FI.
So, when they say: HEY BRO, I unplugged my phone 1 day ago and my battery is still at 30% and then they put a graphic on it you can see that about 20 hours the phone have been deep sleeping. Then you use it and PUFFF!!! A huge percent down...
I don't know if you know what I mean, english is not my first languaje... But what I'm trying to say is...
Battery life is most of the times the same WHEN USING THE PHONE!
Dude stop worrying too much abt battery... Simple battery rule. Charge it when its less than 20%... Let it drain by its own.. Then charge again... There s something called life explore it...
WOW!! What a superb reply... Great, wonderful, splendid...
You're so wise... OMG I can't even believe you took time to reply my request... Thank you Oh Lord!!!
Sigh!
My battery drains so fast on my home wi-fi I tend to browse whilst charging for most of the time (I'm sure it's not recommended). Wish I knew where people get the improved stats for wi-fi over 2g/3g from.
Of course samsung is gonna claim great battery life, they have to sell.
On my experience, i use the phone constantly with 3g for whatsapp and music all the time. I still charge it every night and thats ok. Its a smartphone, a micro computer. Unplugg your lap top and see how long it lasts! If you cannot get a day of battery, youre using your phone too much. The biggest battery hog is your screen, turn it off when not using, lower brightness, dont use 3g and 2g at the same time. Otherwise, get a stupidphone and marvel at your 5 day battery life.

The point about WiFi/3G/2G and battery stats is that if the phone isn't having to work hard to get its connection then it won't drain so much battery. So for example, I have almost no 3G coverage and no WiFi hotspot for miles, urgo if I have them both on the phone will search hard for them and drain battery. I have only 2G allowed and that works for me.
Technically if I had a WI-FI hotspot I should use that because it should provide better coverage than either 2G or 3G, and so the phone won't have to work so hard to get connectivity.
How strong is the signal for your WI-FI, is it very changeable?
I sit about 2m below it and it locks in seconds, varies between 2 and 3 bars on indication. Perceived drain is battery falls from 100% to charge warning in 3 - 4hrs approx.

my ace drains battery fastest when i play games,when playing any game 10-15 minutes my battery drains for like 10%
i have good battery life ,,about 36hours when using wifi
the problem of my battery life only happens when the phone is on. I've tried turning it off for a few days and the battery held up too long. So my advice for the battery last long, its always keep the phone off, and use it to shoot on someone's head (devs?). You may even withdraw the battery, lasts longer without recharging.
I suggest that someone makes a rom that doesnt work and keep the phone off, and we will have long battery life

In my case, I've had the best battery life duration with StockRom Lite, AceOne (this seems to fly in my phone).
The AceOne rom seems to "survive" between 16- 18 hours in my chase listening music, checking some emails with 3G (not 16 hours, time by time).
I've installed a rom made by Nathan (TouchWiz) and I was worried about the battery's duration, but since I've installed nims kernel it works better, I'm gonna view how it works
The only problem of mine with SGS 2 is wake up lag. Pressing power or home button when screen is locked and after a call, screen wakes up 2 seconds later and this makes me crazy and i want to throw it when it happens.
Do u guys have any ICS ROM suggestion that has no wake up lag?
You're not going to remove wake-up lag without keeping a permanent wake-lock.
You can help to reduce it by not using a kernel which is by default utilising a governor inhibiting screen off CPU frequency.
No wake up lag = no deep sleep = battery draining very fast.
I guess you can grab an app that mantains a permanent wakelock and you won't have that lag. Your battery won't last long either.
I'm running Resurrection Remix 1.1 with the Siyah 3.0.1 Kernel. When you mention wake up lag, I can't even imagine what you are talking about because I have none whatsoever. And my battery goes all day with heavy usage and I still have at least 45% left when I go to bed....

Auto brightness, turn it on. NFC, Bluetooth turn it off. I always suggest that users turn on extended standby mode but some people want their whatsapp or email to come through instantly all the time which I can understand but it's a real life saver for me, I personally don't have a massive issue with my battery, lasts a whole day, sometimes less if I use the phone heavily.

You could use clockwork recovery to erase the battery stats as well. I don't think you need root for it.
You charge to 100%, reboot into recovery erase battery stats, unplug and boot normal. After that you let it drain on its own until dead.
I've read that sometimes it worked after the second calibration or something but i believe it might be user error.
I erase the stats every time I flash a new rom. ...
I am now on 2.3.7. ... Maybe is better

Battery stats doesn't do anything: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.

I would advise you to update your phone to the latest firmware, it has better battery management... If you are rooted, you can try custom kernel like ThP or Sliding_XP and custom Rom based on stock... I used to get only 10-12 hours of battery life in 2.3.7 before rooting.. The steps I took to improve battery life are:
1) Root the phone, add init.d and build.prop tweaks or install a Rom that has tweaks like Brain_ICS or XPT's Vision Roms.
2) Use any custom kernel based on stock that are tweaked to give better performance and battery life, along with above Roms
3) Switch off WiFi, Bluetooth, NFC when not in use. Or better, use NFC tags to switch settings (like WiFi on only at home, Bluetooth on only in car)
4) Keep the brightness to the minimum setting when indoors and keep it in auto brightness when outdoors.
5) I live in an area which has better 2g coverage. In network settings, if you set the network mode to select only gsm, battery life vastly improves as there is no searching and switching for a 3g connection. Also I find that staying in 2g gives better network clarity. I shift to 3g when I require high speed browsing only.
6) I usually keep data connected with auto sync on and extended standby mode on. If you switch off extended standby off, you can last through the day but only if you reduce the amount of apps syncing and the polling time of each app. In my case, I have switched off syncing for Twitter, facebook, Google+ etc and sync only for Google contacts, calender and Gmail.
7) I also have automated the phone to switch to airplane mode from midnight to early morning.
By the time I get home from work, I have at least 40% battery remaining. On the whole, I get 22hours on average and I have got 1day 12 hours maximum from my Xperia P. And happy with my choice.

Forgot two things:
I keep all location services switched off and turn it on only when required. This prevents the Map app from unnecessarily polling for location and helps save battery.
And sorry for such a long post. There won't be a tldr.

Just had this weird experience, battery was on 1 percent then I rebooted my phone using power button and volume up, then my battery shot up to 28 percent

that was android normal problem....thats why developer making phone by using high capacity battery (motorola razr maxx) . By using 3000mAh battery also just give certain phone for 2 days (using galaxy note 2). Android jelly bean suck battery juice faster because of its f***** project butter (uses cpu and gpu at the same time). Now phone developer starts frustrated on android...hehe (from my speculation)
Android problem how?
Almost all smartphones last about 1 day. Don't blame the Operating System it's the same battery life in all smartphones. Blame the battery technology.

PS: Xperia P, Red, for sale - 2 months old
Does anyone know any current news about this function and battery consumption? Really it consumes more battery? I believe it was something to consume more battery, Sony would report this to enable the option!
It seems negligible. The phone still goes into deep sleep.
hi.im check .do not exceed battery consumption
I don't think this feature consumes a lot of energy. It's a great feature for me, btw. So why disable it? I'd rather use my phone 10 mins less than not using this feature.
Thanks guys for the reply!
I believe if consuming battery, Sony put a warning when activating this option!

@behroozexe, how did you check?
I'm pretty sure it doesn't use battery either. Still goes into deep sleep for me. But if ever it DOES use battery life, it's probably very minimal anyway.

hi dear. i disable all other app and check at 2 period. first with 2 tap enable and then without 2 tap.
There was no significant change
Well I think it just keeps your digitizer on and uses a negligible amount of power ..but correct me if I am wrong !
In a device from Nokia that I can not remember the model has the same function and activate it the user is informed that this option will consume more battery than normal!
Simple! If you want to use such tech then enable it and take risk (if there's any like battery consumption and such), and if not, DISABLE it, cased closed.
I don't notice any further battery consumption using this feature. 3-4h with 1% battery consumption is really good.
Take it easy, pals! Why are you so serious about battery consumption? Be happy and use it.

It once raised this doubt in a thread and I had that in mind! I find it strange it consume more battery and Sony always worried about the battery do not put any advise to enable this option!

@azeter go to settings - display - tap to wake up.
Just to let you know, I have completely forgotten about this feature and started using it since this Wednesday, after comming across this thread.
I have not noticed any effect on the battery life, not noticable as my usage pattern is quite consistant daily and I could tell...
