Xperia X10a Battery Questions

1) How to have best battery life? I currently already
-Turned off Bluetooth and GPS
-Wifi only when I need it
-Using SetCPU with profiles from another thread
-Low brightness
Im guessing that all the apps autostarting uses alot of battery so I always stop them with Task Killer but they just restart. I tried using Auto Task Killer but it doesnt seem to work. Any help?
2) I use like 40% a day so should I charge everyday or wait until its down at a certain level?
EDIT
Also, whats a good video converter to convert videos for the phone? Most that I tried takes forever and my computer is definately not a slow computer.

Stop using a task killer, the OS will handle the apps. If you keep shutting them down they have to keep restarting, that will suck power.
Any data sync will drain your battery if you us it to often, set it to a reasonable time frame.
I leave my screen on auto seems to work well, and you can charge whenever you feel like it no need to wait till it's low.
If you use Rockplayer you shouldn't even have to convert your movies unless they are full HD. It's a great player you should try it out.

Hi, mine goes down at an average of 1% battery per hour at normal use since the firmware update (v23).
I enable wifi only when I'm at home, for the rest I only use Edge/gprs because at my work the 3g signal appears to be too weak and 3G drains the battery really fast.
Bluetooth and gps are off, Google account syncing is on.
I believe that a lot of widgets have a negative effect on the battery life, so it might be a good idea to limit their number.

Ok I found out the major battery drainer via the battery usage in settings. It shows the the Display accounted for 80% of the battery usage. My display brightness is only set at aprx 25% and I have a total of 4 widgets on. Whats the problem?
Regarding the conversion, I am using rockplayer already but I just want to toggle the video settings a bit (mainly resolution) so the file size is smaller.

40% a day is a quite good result. what is your objective for a smartphone with 4-inch diaplay and 1G cpu?

Well 40% is with like 30 min wifi, 1hr gaming, 5 min calling. 3G, GPS, BT all off. But im not out of the new battery draining cycle yet.

More of a wish than an objective but a month would be nice
In the early 80s a 20MB HDD was about the size of 100 X10's and now my X10 has 32GB of storage the size of a postage stamp.
The computing power of an X10 would have filled a 10 story building in 1980.
Where are the big advancements in batteries?
What we need for the X10 is a Hydrogen Fuel Cell

Bottom line is that it's a huge screen and it sucks power.
Try this, turn off "everything" and play a 2 hour movie, doubt you'll get to the end of it.
Since the screen is so large battery life would have been better served by an AMOLED screen rather than TFT.

Gary.. Think this latest firm ware has a bug that shows the display draining battery much more than it really is.. You should ignore that. My display is set to auto. I get a full day from about 50%.

yes, the current battery technology is obviously far behind the development of mobil devices industry. egeryday, we see the faster cpu, better display and os etc. the battery has become a major weakness slowing down the related industries.

Did anyone manage to have 40hrs++ battery lifetime?

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.

Never used iOS devices before...So they have those kind of things hey..
I agree with you with the point that their OS was made for one device, while us is for millions
Thanks for the comment

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.
I always get a chuckle at the iHerd people I see on the bus holding their tiny screen 6 inches in front of their face so they can read it.
If battery life is really a concern get a couple of spare batteries and a charger.

Lasting 40+ hours is easy if you don't use the phone much...
The screenshot was taken on a long weekend a while ago. I was busy during the weekend and didn't use my phone much apart from listening to music for no more than 2 hours.

How to get epic battery life?

Hey guys,
I see some people here have AMAZING battery life. Some people are getting 4+ hours screen on time with a single charge.
I only get around 2 - 2.5 hours screen on time. Which is good, but not as good as other people.
I am using the latest Paranoid Android ROM, and I have tried many different kernels but battery life is the same with all of them. I tried undervolting, still the same battery life.
All location/gps settings are OFF. The only syncing I have is Facebook syncing every 4 hours. I checked the battery stats, and everything is normal. I checked Better Battery Stats and everything is normal too, no unusual wakelocks or anything like that.
I checked my cpu bin in terminal, and it has been binned as a 'FASTER' cpu.
I have very good signal all the time. Always use WiFi, never mobile data. Bluetooth, NFC are OFF, and brightness is autobrightness.
So after all this, why am I not getting amazing battery life like others?
Thank you!

Because you use the phone and the others no! I have similar battery life. I get 3 hours screen on time.
Try cyanogenmod. For me is the best rom.

Heres a few things that help me:
make sure if your on a ROM that has it to disable cell broadcasts in wireless & network settings.
In Google sync settings, uncheck everything you don't use or can manually sync. The only things I leave checked are gmail, contacts & calendar.
If you've opened maps, make sure to back all the way out of it & swipe it away from your recent tasks screen. Better yet, if you don't need it, uninstall it or use an alternative like mapquest app.
If you don't use Google talk, open it and sign out or uninstall it.
Try not to overdo it with widgets on your home screens. I mean a few is cool, but when u have 5 screens all jam packed with various widgets constantly running & syncing...
I know you said you've tried various kernels, but I honestly found that I got the best screen on time with Franco r86 kernel (just over 4hrs). I'm not a huge kernel fan so I haven't really tried others, but I was only getting just over 3 hrs on stock.

I use the greenify app to hibernate facebook and words with friends it helps somewhat on battery life

I recently discovered that if I reduce the brightness down to 50% (which is still very BRIGHT), I can get an extra 30% battery life.
Simple, and yet, effective

Turn the brightness down - even 10pct is plenty bright indoors.

Try Eugene's CPU Sleeper from the market. It turns off all but one of your cores while the screen is off to minimize cpu usage. On CM nightly with stock kernel I got 34 hours with 17% remaining and 2.5 hours screen on time til I ended up charging my phone. I run my CPU at 1350 max / 384 min.
Make sure under sound settings all the sound on touch, keypad, etc are all turned off. Each time your phone ticks a sound it uses battery. Also bright display backgrounds will use more battery.
I only sync chrome, calendar and instant upload
good luck

You can also try this, it takes a few days to "learn" your routine then it supposedly starts saving battery. I'm currently in day 2 of learning mode so I don't know for sure how well it works. But it seems to be getting good reviews so far...

Well it basically learns your routines and changes your sync settings, turns WiFi on/off when needed, and various other things you could do yourself but might forget. Kinda like tasker for lazy people so in theory yes it could save you some battery.

Tried his kernel already a few weeks ago. No real change in battery.

That seems weird
I am completely stock, and set things more or less the same with you (not syncing, no gps unless needed, on wifi all the time) and I could get over 4 hours screen on time on an 18 hours battery life. I believe this phone (chipset?) is really efficient on standby. Does your phone show that it's being kept awake much using the cpu spy app?

Same here... I'm on stock and the best i got was pretty impressive i think. 49 hours with 4 hours screen on time. I waited till the phone turned off by itself Even though i don't get that with heavier use, it's still enough to take me through a whole day which is better then my old phone
My battery saving tips:
-turn off everything you're not using (wi-fi when not at home or office/school, bluetooth, gps, low brightness indoors)
-swype away apps after you exit from them
-turn off the screen when you put it down/in your pocket etc.
-turn off google now
That is everything that i do. No sync disabling, undervolting, underclocking or other tricks

That doesn't do anything. Android as a native app killer. On the other side, this would lead to more battery consumption as Android would have to initalize data the next time you open that app. IMHO leave the apps as they are, Android would take care of them and kill them when required.

IMO it's isn't as powerful as tasker, but it's giving some extra juice.

Post your battery life here!

I've been noticing and reading many many posts regarding how bad or optimized our battery life is.
I had this phone little more than 24 hours now. And I feel like it hasn't fully when through the battery cycle. Thus killing my phone in less than 10 hours. This is with very light usage as well!
I've also turned off gps and wifi.
I have turned on stamina, along with various other battery saving features.
Now I am coming from galaxy s3, note 2, and iPhone 5. (my iPhone has this same issue and cleared when I've started using the phone and going through few charging cycles)
I just wanna make sure that our phone isn't plagued by the software, hence this phone is only available via t-mobile or Sony (unlocked as well).
Please post your battery life photos.
Including rooted or not.
Also post which rom / kernel you are using.
Mine: stock from t-mobile. And not rooted.

We already had/have a similar topic in the Q&A section, no need to open a new one.

I see a lot of wake events. Check what's keeping your phone from deepsleeping with wakelock detector.

Yup you have a lot of wake events, I had this problem too. I reseted, reflashed firmware multiple times and still experienced problems until I sent it to Sony and somehow now there is barely any awake entries at all. Only screen entries appear (blue line on screen) and no lines on awake.. I do still get *backup* wakelocks and some qcom_RX_wake lock though

i get about 20+ hours of stand by and around 3-4 hours of screen using it normaly not playing games

The phone was horrible initially and on 4.1.2 then after the 4.2.2 update it has been brilliant. It lasts me just over 24hrs on normal us with screen time between 5-6hrs. I'm very pleased as by 17h00 it is normally at around 55%. So it lasts me a full active day.

After 4 months my Xperia Z barely lasts a day with just 1,5h of screen on time. Sony said the battery is good. Restored different firmware, tried 4.1, 4.2, CM - nothing helps. I'm very unhappy...

The media server keep draining my battery...
But when I switch my sd card to a empty one or just remove it the media server nolonger drain my battery.
So I only keep a small amont of pic and musics in my sdcard and that makes the battery can last more the one day

the battery life was improved from 4.1 to 4.2 . That being said, the battery life is still much to be desired.

Tbh I was really worried about the battery life on the Z, I have had my phone nearly 24hours and I am not concerned by bad battery life so far. The battery seems very good actually, its no S4 but the S4 does have a bigger battery and uses a AMOLED screen. Iirc LCD/TFT use more battery or maybe I have got that wrong.

I'll assume you are not a heavy user of some sorts? The frequency of usage i mean.
I'm not sure about the screen part though but it does make sense if AMOLEDs screen uses less battery than LCD/TFT screens since they actually off the black pixels.

Don't we already have a Thread and lots of results for Battery life here? http://forum.xda-developers.com/showthread.php?t=2185362

Stock rooted 4.3. No undervolt, no nothing, just stamina mode on. This is the best update I ever had on a phone in terms of battery life.

S5 Worst battery ever

Got this phone about 10 days ago and my battery is terrible since day 1, someone suggested to root my phone and get the BBS app and dump a file i did that and installed a system tuner to disable google CHECKIN OR GCM and unchecked them. apps i got installed to help with battery battery doctor, wakelock detector, os monitor, system tuner, gsam battery, betterbatterystats.
Apps i disabled are:
Ant radio service
Ant+ plugins
App zone
Blurbcheckout
chaton
chrome
flipboard
google play book, games, movies, music, newstand , google search, google+ , hangouts
hp print service plugin
my magazine
s health , svoice , samsung account , samsung apps , samsung galaxy apps widget, samsung push service, smart remote , Top Hd Games
got a plain black wallpaper, even after all this i cant get more than 2h30m screentime and everyone is getting 5h+ do i have a defective unit? what are my options right now? cause basically i removed everything the phone has lol. i talk to my workplace and they can send the phone for repair but i want to see if someone can help me before i do that. i have to unroot the phone if i have to send it for repair even though my phone is 0x1 on knox cause i was stupid to root with cf-root and didnt check other methods.

After all that you did, then it sounds like a faulty battery or device.

How's your signal at work? I'm on 3g at half signal maybe? I get about 3:30 and standby. But when I'm at home WIFI only I get about 4-4:30 it all depends too on how bright your screen is.

How do I check if I have a good signal at work? Through an app or through a battery status.

This system tuner app you used it not any overclocking or something that might drain you battery?
What screen brightness do you use most of the time?
Can you see what use most of your battery? There is charts you can access in settings -> battery
I run with BLAZE kernel and Alliance ROM. (install without any samsung or google bloat if you can)
And I have been using my phone constantly, playing streemed music, installing apps, downloading from internet, browsing internet, having screen active a lot...
And Now I'm at 87% and have been running 1 hour and 38 minutes on battery. (Was at about 100% battery before)
I run +5 screen brightness and don't have any special powersaving features running that limit my experience with the phone.
You could try that kernel and ROM too, I feel they improved my battery time a lot.
I also shut down some samsung and google bloat stuff like air browse, s voice and such crap, saving a little little battery.

Here is my battery info and my brightness level. I have Canadian g900w from Rogers so I am not sure what roms or kernels you can use ?

Hey, here I have everything turned on and I never followed these stupid extreme battery guides and I easily get over 4 hours of screen time and one day away from the charger. I only use auto brightness, Greenify and KT Kernel.
It's a smartphone, if you're supposed to turn all the features off then you should have bought a dumb feature phone.

Looks like ur using max brightness? Nearly 2 hours screen on time for 44% isnt the best but isnt terrible. I get around 5 to 6 hours using low brightness 3g/4g on besides when screen on. Using android tuner and greenify for tuneing. Screen uses a lot of battery to. Im using. Ktoons kernal now with oc and the batterys probably the same to to me. No beter or worse but. Im running higher clock.

You're set for almost four hours of screen on time there, on what seems to be very poor mobile signal. Doesn't sound that unrealistic to me to be honest.
Poor mobile signal absolutely kills battery life, as your phone spends the entire time searching and trying to get a better signal.

I think his point is that most people get 5-6 hours screen time with everything on and without following the "stupid extreme battery guides". To be honest it looks like you aren't getting great life either if you are only getting 4 hours. I regularly get 6-7 with everything on and no greenify or kernel tweaks

I see a couple of things interesting with your setup, Speaking from personal experience, I too have had battery issues drive me up a wall. I'd get just about a day on a battery when everyone else gets about 3-9 days more. My friend has an s5 all stock and he gets 9 days on a freaking battery. WTF
I rooted my first s5, with ANCH baseband and still couldn't solve all the issues with it. So I sent it back to t-mo and they sent me another one, getting batteries on ebay has also ended up a wash. 2 batteries I've received go down 20% from a full charge in the first hour and shut completely down at 32 percent at least I got a refund on that. (So be careful about ebay batteries, even though they say samsung.
So looking at yours here's what I see, Your system is staying awake, lets look at wake locks. Kik is really tearing up your machines wakelock (900wake locks) as well as the camera CPU time, i'd imagine you were recording a video at some point.
1. Go get greenify and greenify those Kik, Instagram and camera apps if thats usage while the screen is off. (No notifications on those apps, i'm afraid when you do that.)
2. Go get system tuner, make sure your rooted by towelroot (If you so choose to keep from tripping knox) and go into app mgr and find android system and go through activities, receivers and services and make sure everything you see that says IQAgent gets unchecked. This will help you stay out of ServiceIQ's eyes and also help your battery as your entire phone is debugged through those apps. (Help is on the forums somewhere)
3. Turn off google now, hotword detection and location history or you'll start noticing Google services draining your battery
4. Go get deep sleep battery saver and remove that battery saver, I personally never liked it it only suggests things to do rather than do them for you. At night or whenever you need to save your battery turn on slumber and it will only take like a percent to 5% in the morning
5. You probably have a bad battery, especially if its down to that low. Time to exchange or return
I'm incredibly disappointed, i've had to do all these things to really figure things out, heck i'd be on firefox for about 15 minutes and go down 18% (Happened this morning)
Android really has some issues with kitkat, and even though we try and fix these problems with modifications there comes a point where one just gives up and tries to deal with it.
I don't understand why my phone gets 1.2 days and my co-workers Verizon s5 gets 9 days with normal usage. Everyone seems to have crazy all over the scale battery life results. Heck, i've reset my phone and flashed so many roms that i'd be safe to say that I have yet to have 10 full discharges in the 4 weeks i've had the phone. At the end of the day though, it's mountains better than my iphone 5 with a lenmar battery case.
Wish I could say the same with stability, I'd be on my bike and switch tracks (or try) and stuff just doesn't respond, heck I can't even go with voice activation with wired headphones and that is really a downer for me. I want to be able to hold down the pause and play and get the google now boop boop sound and speak as i'm riding.
I'm tired of this, and google has no answers, the fixes above only seem to add a couple of hours but not the 9 days I was seeing.

So? What do you do to have that many hours? Which rom? How often do you recharge? Which apps do you use? That's the point. I never freeze/uninstall anything...

My rom. With nothing removed or frozen as I have to keep all bloat due to development to check everything. I recharge every night usually with about 20% left and about 5h30 screen on. Using Tapatalk, music, calls, Internet. The usual stuff.
Sent from my SM-G900F using Tapatalk

I get 6-7 hours normal use with the bloatware I never use frozen. And I mean never use.
Gtalk, whatsapp, line, google drive, dropbox, gmail, Yahoo mail, corporate mail, all running. No greenify. No battery saver.
Now playing games is different thing. 2-3 hours max.

My battery is amazing. I keep the screen brightness lower, keep networks and chips off when not using, i use bootmanager to prevent apps from launching ay boot and only 1 active widget. Good for a day and a half of very fair use !

Yup probably, the only flaw with a smartphone is its user
