I've had a very sudden and dramatic improvement in battery life and I thought that I'd post what seems to have worked for me.
I installed setCPU and set it for
768/254 on demand - main
245/245 performance screen off
368/368 performance - battery<41%
battery<101% 768/245 on demand
I installed Ultimate JuiceDefender and set it for extreme - blocking all connectivity except for a white-list
I decided that I could do a better job than the auto screen, so I installed Brightness level and I keep it generally at about 20% and then flick it up a bit if I need it.
I disabled auto rotation and now toggle the screen with a widget.
I've taken phone calls, recorded phone calls, checked email a few times, tweeted - very often using wifi which I operate using a toggle widget
I had the phone on charge all night switched off.
Disconnected it at 8.00 this morning and at 6.30 this evening, the JD widget tells me that there is still 12hrs and 28 mins of battery time left.
Considering the size of the screen and what this phone does. And considering the very poor battery life - 8hrs max I was getting before, I am far happier and the phone now becomes a practical item to have.
Whats your percentage battery left?
seems to be saying 72%
I also noticed that for the first time screen usage is less than running usage.
Screen consumption has always been the big factor on phone - and I see that is what people say on the forum, so I'm very pleased to have reduced it so well.
The Brightness level app allows a variable control whereas all the other screen controllers have seen allow you only to rotate through three or four preset brightness levels.
Brightness Level lets you do that with a widget but it also has a slide bar, which is what I was looking for
So basically you've downgraded the DHD to a level of a Nokia S40 device imo As this has been covered by many others in many other battery life related threads I'm just saying this short and simple. Just use the device as it is supposed to, enjoy the awesome features it provides at the full potential and don't get fixated on the battery life, it'll get you through the day no problem (doesn't include playing angry birds for three hours straight ) and just plug it in when you have the chance.
About battery, some tips, my battery life is around 2 days with normal usage of phone, only i dont use 3g only wi-fi:
Brightness - between 25% and 50%
When you on the internet and use native explorer for android go to "Menu-more-settings-enable plugins" and set it to "On demand"
Tupe *#*#4636*#*# - "Phone information" and set "Preffered network type" to "GSM Auto Prl"

your on stock rom mate?
i can see that you can charge your phone while its turnd off..
i think on customized ROM like ARHD LD CORE cm7 and etc cannot charge their phone while its off because iT will BOOTup to recovery mode
Doesn't performance mode just keep the CPU clock on it's maximum? It would rather shorten the battery life than prolong it.
Why buy a smartphone and use it like a landline lol i hammer my phone and still get 10-14 hours out of it, thats fine for me, i only get 3hrs out of my laptop lol

Mate there is something eating your battery if u only get 8 hours battery life.
These adjustments you made are unnecessary if you find the culprit that is eating your battery, why get a phone like the dhd and run it on 20% brightness and lower the cpu to such a level.
Have you used spare parts to check your battery usage?
Im currently on 40% and my phone has been unplugged since 27 hours and I don't even have setcpu installed.
Maybe you should post details on your barret usage!
Swyped from my sexy galaxy tab
But I'm not compromising anything now. I'm completely happy with the way that the phone works for me now.
I'm actually operating the screen at 12% for most of the time - when I am not outside and it doesn't present any difficulty for me.
Obviously I would always like better battery life and I'll look for more ways to improve it.

According to setCPU, if you set it to on demand, it will keep on scanning for required power level. Performance automatically goes to the max. Apparently on demand uses slightly more power so they advice to use performance when possible. So I set the same max/min figure and use a performance governor.
i would actually consider rooting the phone as an alternative, or getting a bigger battery. i have alot of issue with the battery life previously, but after switching rom, it actually help alot
Well it is rooted to enable JD and setcpu to work. But I haven't dared go further because I am still trying to understand the entire process - and also the way back!
I probably will eventually.
I've ordered a 1500 Mugen - and if that actually exists and if it is an improvement on the stock battery then that will advance things as well.
I'm very pleased with the improvement I have achieved so far because at least I'm able to take the thing off the tit for a full working day and use it as a real mobile phone!!

Yup2x, it's true that we can charge it very well while in recovery mode. I was referring to the situation wherein the printer reboots to recovery as soon as you plug in the charger to your DHD. Some users have reported that and they are all using 3.x.x.x.

As far as I've understood, you will always have max frequency when performance is applied. So there is no use setting min value really as it doesn't matter.

By far the most excellent advice. I totally agree with you.
I know people are always complaining about battery performance, or see stories of how someones phone will go from 100-40 in an hour and half to two hours. I think I've found a solution (notice how I said I THINK). I've seen random battery fluctuations on my device for months now, some days it lasts longer than others (obviously data off, wifi off, and all that good stuff) but the battery life would still be eaten away like crazy. Here's what I noticed a few days ago: I went to sleep and when I woke up the next day my battery life had dropped 20 percent overnight, and everything that sucks battery was off. It confused me because that doesn't happen unless I leave data or wifi on. So I looked through the phone and I turned off "Standalone GPS services" one night and went to bed again. The next morning, the phone battery had only dropped 2 percent!
tl;dr turn off Standalone GPS under Location and security settings. IT may help your phones battery life significantly
Hope this helps with your battery performance folks, and if this has been brought to your attention already, then sorry for the repost!
just thought i would reply
first of when i sleep if i need the alarm i turn the flight mode on as the battery only uses between 1-4 % a night normally 2
i dont have a standalone option only turn gp on and off
r800i 2.3.4
but i dont have any battery issues really if my battery is draining fast its because im playing a game or browsing the web alot
a good tip is
use wifi instead of data when a wifi network is available but keep wifi off when not in use.
too many people either leave wifi on all the time which wastes alot of battery or never use wifi as there confused and always use data connections even when at home (major battery killer)
What happens with my battery is that if I leave the phone on standby overnight it'll gain about 10% and that's not even in airplane mode.
But as usual my battery does drain quite a lot when playing games using wifi and all that. Using EDGE drains more than using wifi.
I always charge my phone every night so would turning off the gps help much during the day?

This is about Li-Ion batteries. Xperia PLAY's stock battery isn't Li-Ion, it's Li-Poly.

Each has its own pro's and cons. Here is a list:
Lithium ion:
-The lightest of all metals
-The greatest electrochemical potential
-The largest energy density for weight.
-The load characteristics are reasonably good in terms of discharge.
-The high cell voltage of 3.6 volts allows battery pack designs with only one cell versus three.
-It is is a low maintenance battery.
-No memory and no scheduled cycling is required to prolong the battery's life.
-Lithium-ion cells cause little harm when disposed.
-It is fragile and requires a protection circuit to maintain safe operation.
-Cell temperature is monitored to prevent temperature extremes.
-Capacity deterioration is noticeable after one year (whether the battery is in use or not).
Lithium Polymer:
-Lithium polymer chemistry differentiates itself from Lithium Ion in the type of electrolyte used (a plastic-like film that does not conduct electricity but allows ion exchange - electrically charged atoms or groups of atoms).
-The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
-The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry.
-Cell thickness measures as little as one millimeter (0.039 inches).
-Can be formed and shaped in any way imagined.
-Commercial lithium polymer batteries are hybrid cells that contain gelled electrolyte to enhane conductivity.
-Gelled electrolyte added to the lithium ion polymer replaces the porous separator. -The gelled electrolyte is simply added to enhance ion conductivity.
Capacity is slightly less than that of the standard lithium ion battery.
-Lithium ion polymer finds its market niche in wafer-thin geometries, such as PDA batteries.
-Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Ice Cream Sandwich (Beta) already has this feature off by default.. but great tip anyway.
yeah i know my battery sucks too but it vary's sometimes
You could try out apps like juice defender. It disables your data connection and enables it every 30 minutes for example, to update whatsapp etc. When I am at home, I use our WiFi network. My play has the best battery life of all my friends phones and I'm a heavy user, playing a lot of games and using the internet too.

You need to try the ultimate version. You can select what happens on specific apps. So apps that dont use the internet, the data will be disabled whilst playing them
Also, you can set it to automatically turn data on/off depending on your location so you connect to wifi at home ect
I find it very useful

Dear People,
I am posting this out of big ENVY from my friend's story of his iPh*** 4 battery life with 40hrs ++ of usage (social network on, moderate usage, data always on, bla bla bla) and he still got 20% left of his battery!!!
I was just wondering did anyone managed to experience 40hrs ++ of battery lifetime? My best achievement with my nexus s battery life is
1 day 3 hrs with
MIUI Rom JB 2.8.17
Marmite Kernel 4.3
SmartassV2/deadline
100/1000
Automatic brightness on
Could we EVER achieved 40hrs ++ battery lifetime??? Since Iph*** 4 has practically same specs with Nexus S
It has 1Ghz procs, 512mb ram, 1500mah battery, bla bla bla
Any comments?
A very big advantage of the iphone is the very dim (to my opinion) screen backlight. If you change that to default 1 min instead of 20 on a custom rom, and then change your auto brightness values as well to lower ones your lifetime should increase alot. At least mine does. Also I use Llama to close mobile data after 5 minutes of sleep and then instantly turn it on on unlock. Anyway..we will never be able to win versus apple at some things. They have one operating system made for one device. We got one operating system for like..1 milion devices? That's the same story of console vs pc games.

I've been getting pretty excellent battery life lately, will put up a screen shot but got almost 52hrs battery life with wifi and 3g on until it got to about 15% with about 2h 24m screen on time, although this was pretty light usage to be fair.
Using codename 3.3.2 with standard kernal, I turned NFC off and this seemed to help massively although I've also heard the new Maps app has solved some battery drain so not sure which has contributed the most.

52hrs?????? Cant wait for your screenshots man!
You may think the specs are the same, but the hw in the iPhone and power management is still superior. They get a push notification, even while the 3g radio is in idle and almost off (in which it saves more power). It's hard for Android to optimize the power management specially because of that many hardware variations, it's not only the CPU that counts.

Well, thats good to know, but since its the software differences (meaning coding and stuff), surely (i assume and hope) that we could also applied it (somehow) in our devices through tweaks, can we?
IMHO not much is possible since this is older hardware already and a question for how long will Google bother with it. It might be alot of work needed and you gain some insignificant amount of savings.
Would be nice to see some kind of power management tweaks in coming version of Android though.
well its halfly because android works differently and half way because of the hardware.
yes, the hardware is similar, but the nexus screen takes up more power, the processor is not very efficient, and nfc takes up power... also, the 3g radios are honestly HORRIBLE on the nexus s and that might have something to do with it.
but, the software side does make a major impact. iPhones do not multitask like android, which saves power on slower devices like the iphone 4. thats only half of it though, for instance, the iphone 4S has much worse battery life than the nexus s (by far). ROMs make a big difference also, I am very picky when choosing a ROM- if it doesnt have great battery life then I immediately replace it by another ROM that does.
I get on average about 16-20hours pretty consistantly if you are wondering, and I am OK with that as long as it makes it to the end of the day... I wake at 3:30 and normally it does. My advice is to experiment with different ROMs, I would suggest some, but I use an S 4G...
I don't really believe it. My friend has an iPhone and he uses it quit a bit and seems to have to keep it plugged in as much as I keep my phone. I think he said he usually gets about 8 hrs out of it. And the screen is pretty dull compared to mine so that might make a difference to

The iPhone screen is a lot smaller too and that's a big tradeoff.

Yeah, I managed to squeeze out around 15 hours on my Mini (around 14 hours screen on), on Wifi browsing 10~, 2~ hours on Pdfs, 2 hour video, 1 hour music with screen off.
Brightness @ 55-60%? not entirly sure but somewhere around there.
That again, its fully data on Wifi and not 3G.
The Mini does seem to use RAM a lot more efficiently, It does run a like 2 task in the background and pauses the rest doesn't jerk up (99% jerk free).
Tab runs a huge ton of apps in the background without pausing intensive ups, it uses up RAM fairly heavily and jerks up a bit. I find myself constantly tapping on the multi-task menu killing background task dispite having 1GB<-Thats a touchwiz ROM btw haven't tried AOSP on that.
Besides that, Ti OMAP 4430 vs Apple A5 2nd Gen
Both Cortex A9 Dual Cores running at 1Ghz, Ti uses 45nm while the second gen uses 32nm (More power efficientcy)
Both have PowerVRs, Ti has a Single Core PowerVR SGX540 @ 304MHz Vs A5's Dual Core PowerVR SGX543MP2 @ 250Mhz/core
Overall, I believe it has more to do with Android's base. It is written on Java as a pose to C+ like iOS. Java needs its codes to be emulated on a virtual machine while iOS runs it nativly.
If Android can be coded in C+, It will take away CPU cycles and we could see a drynamic improvement in battery life, speed, literacy and closer CPU and GPU integration.

I second "Greenify" suggestion. It has almost doubled my tablet and phone's standby time.
I had improved my battery life using old method such like for my HTC . No it work about 48 - 50 hours on medium use.

That's pretty bad for the battery... Fully (as in FULL) charging the battery is not good for the long term.

The tab stops feeding charge to the battery when it's full. Leaving it on the charger has no effect positive or negative

I believe its the kernel.

Do you suggest that it is better to keep plug the charger even though already full.
Is there a Charge and Discharge Counter or something like that, just like a notebook, that would shortened the battery lifetime?
In that case, it is okay then to let it charge over the night, right?
The one your describing is called charge-cycle. Every battery has one. Its better to fully drain your battery once in awhile so the cell on your battery wont solidify. Do it maybe monthly. On notebooks we can remove the battery, and use it plugged-in so it would not wear-out the battery fast. Plugging your device while the battery is still installed is different from no battery and plugged-in at all.

Its been about 2 weeks since I got my phone and I'm mighty impressed with the battery life, probably because of stamina mode. I know it's only this good since I also haven't installed too many apps on it yet, but it's still much better than any android device I've ever had before.
Shame the battery isn't removable though. How's the battery holding up on your phones?

Holy crap, what's screen on time like? Performance?
If you post such a screenshot you might aswell tell us the trick that did it I could get 4 days out of my phone on stamina mode and this was with some hours of music and music browser of course, but not much more.
the best that i have seen on my phone is 45 hours ( almost 2 days ) but with 4.5 HOURS SCREEN! too much i think!

I use mine moderately most days sometimes heavily and I still get about 1.5 days usage.
Stamina mode is very impressive indeed. :silly:
regards
No tricks really. Here's how I've been using it.
Settings:
Bravia engine off
Mobile data off most of the time
Wi-Fi on most of the time
GPS off
Stamina mode on of course
Apps:
Streamed a video episode
Streamed music (on chrome)
Played music (on app)
Took pictures
Used flashlight once or twice
Sent a couple of files via bluetooth
Yeah its generally light usage, but again I suspect the lack of apps that have running background services are also a factor in this. Apart from Gmail I don't have any other email or social network apps set up yet. I check my accounts manually on Chrome.

9 to 12 hours
Hmm, well that's just great. Thing is I have cleaned all the bloatware from my device and I dont use social media, I do have whatsapp and gmail+google calendar running. Normally I get 2 days most out of one battery and this is when stamine mode is off because of whatsapp. But maybe I should try data mode off, wifi on and see what will happen that way. There is almost no situation where I'm not near wifi which I can connect too Still I think using whatsapp a lot eats battery.
I'd love to see 3 days with average use on this device.
My results are just shi**y!
My brightness is on auto.
Data always off.
Sync off.
No other apps installed, which are running in the background except whatsapp.
Stamina is on, for sure! But the battery life is anyway very bad!
5.5-6 hours of screen on time isn't mind blowing. My friend's iPhone 5 gets 8-9. What's surprising is that this has a much bigger battery, and even when the brightness is low and the CPU is underclocked it still drains the battery faster than similar devices. I don't think it's very efficient....

What, no, I'm just saying that with a 2370mah battery and only a dual core, it should be better xD

and asynchronous dual-core should make battery life better
well he doesnt seem to use the phone to play or use apps.... so if it is idle all the time you can pretty sure get even more out of it. If you set a cpu-profile for screen-off time, it will be hardly losing battery. I did that on my old phone and despite it was lagging when waking up it lost less than five percent over a week while i did nothing but checking clock from time to time
Greetings
ps it is said that screen-off-profiles are not good for processor.... but i don't know anymore where i read that

I haven't checked the screen on time and I already charged my phone yesterday. I'll check it again when it's needs a recharge again and post it here (it might take a while lol). Also, not using any performance altering apps or techniques, is there a certain way you check performance?

Whatsapp does eat up a lot of battery. Since I charged my phone I've been using Whatsapp and the phone is already down 20%.
I don't know if this affects battery or not since I haven't tried it before on any other device, but I'm using 3 home screens instead of 5, I'm gonna try adding back 2 screens on the next charging cycle and see if it makes a difference.
I might have a look into changing cpu frequencies when in idle then. For now I'm with a HTC One X because of dead pixels on my SPs camera sensor.
The HTC(nVidia Tegra3) has less battery capacity but with average plus use it gets two days easily, makes me wonder what is wrong with the Sony firmware....

Do you know, that in Stamina mode you can allow certain apps to run.
So turn on Stamina mode, long press on stamina, and add Whatsapp.
mine loses 10% when im asleep lol. with stamina mode on, its around 7%

I did know this but I thought the stamina mode switches of the 3G connection, when the screen is off, which is needed for whatsapp or am I mistaken? Thanks for the hint.
I'll try, my phone should be delivered home tomorrow morning

You haven't really thought this thoroughly
The iPhone cpu runs at 1.3 ghz vs 1.7 ghz on the SP
The iPhone Gpu runs at 275 mhz vs 400 on the SP
The resolution is lower than the SP, which means the GPU on the iPhone doesn't have to work as hard
My Xperia SP still runs longer than my friends iPhone 5,
Easily get two days use out of it, screen on time of about 5-6 hours
That's not bad,
