This is a post from the Xperia play forum about battery life. Since the new Xperia phones shares a common software maybe the Mini is affected too?
http://forum.xda-developers.com/showthread.php?t=1238230
I'm gonna try and see if there is any difference for me on the sk17i.
good idea
nice, please let me know if there will be some difference for sk17i
thanks
well i tried it, and im sorry to say that ... but it doent change anything
Let me here give you and example of how bad is this phone battery situation is .
I have an HTC HD2 running android 2.3.3 and it has a 1GHZ processor which is the same with the xperia mini pro i bought , on the other hand the HD2 has 4.3" screen while the mini pro is only 3" so I already nticed after using the mini pro that its consuming so much battery than the HD2 but i wanted to be more specific so below are the details
HD2 Battery is 1230mA, xperia mini pro 1200mA ( Almost the same )
so I left both of them in idle for 8 hours ( wifi is on both have the same apps like facebook , google+, twitter, with the same update settings, )
the HD2 dropped from 82% to 71% in 8 hours in idle (Lost 11% )
The mini pro dropped from 100% to 50% in 8 hours in idle ( lost 50%)
for me this is a big gap between the two devices and to be honest i expected the HD2 to have a shorted battery life conidering its much more powerfull device and its 2 years old with the same 2 years old battery.
and i also noticed that during the test:
the HD2 never exceeded 10mAh consumption at all
the mini pro rarely went below 50mAh and the minimum was 26mAh
so i guess there is something that eats the battery during the idle time and it is taking alot of it comparing the two devices.
in fact when i bought the mini pro i wanted smaller device that will have a better battery life , but now its totally the opposit which make me confused.

Maybe very little actually.. but I'm gonna keep at manual.. no need to auto scan when I'm locked to one operator anyway.

I have been struggling a bit too with battery life. But with my current settings I have 21hours since charge and I'm on 65%. (so thats about 2.1% each hour) But thats not standby only. I have been using connectbot, some browsing, facebooking, whatsapp.
wifi on all the time and push enabled for activesyncemail, facebook+googleplus+twitter notifications, whatsapp messages and gmail.
I have disabled 3G and set my operator manually and most important of all I have unchecked the Allow wireless network-option in Location and security.
Did attach two screenshots showing the battery usage. I had to connect the USB-cable to take those (with ddms) so it did charge for a minute or so (same thing abit earlier so it shows a small charge period for 1-2 min)
A bit funny also that it shows battery gain in two places (which wasn't when I had the device USB-plugged) and also it looks like something has been keeping the phone awake while the screen hasn't been on.
But as you say it's not very often down to 10mAh as you get on the HD2. (3rd screenshot)

WOW i really envy you now , i should find whats making mine drop that fast in idle while yours can last that long while using it. i will check the settings you specified and report back the results
I attached a screenshot of the HD2 idle usage
Wifi
I've found that the culprit for mine is the Wifi.
I went from ~8 hours to 32,5 hours(is just about to turn itself off) by turning wifi off and on only when I used it.
This is with me watching a 40 min mkv show, and playing myth defence for 30 minutes and a little talk and sms and searching the market.
Wifi location function has been off from the start.
It's a bit weird because on the x10 mini it turned off wifi when the screen timed out and it held for about the same time, so maybe it's a "feature" they forgot to implement on this phone.
On normal usage mine lasts max of 2 days and thats pushing it. Normal use means I do browsing on it via wifi for maybe 10 minutes at a time per hour I guess. Will sync to wifi every 15 mins for 1 minute then off (via Green Power app). To help the thing, I am downclocked to 122Mhz on idle, max to 800+ on load via SetCPU, always on minimum brightness. Playing with autostarts too to disable apps to run and eat memory as well.
There is a higher capacity battery thread

At 10% the phone suddenly dropped to 1% and it did shutdown.
Something is draining the battery during the sleep and i cant find it.

Yes, this thing happens to me, 30% them immediately 1% and stays on for maybe 2-3 mins then dies (when in heavy use). I will recalibrate the battery stats when the phone is fully cycle charged (drained to dead, and charge on AC overnight). Hopefully should fix the issue.

Check the battery usage what consumes it (Settings, About Phone, Battery use).

yeah. it died again at about 10%, I did plug the charger and switched on the phone and it went directly to 10% again. Unplugged it and it died after a few mins. Did pull out the battery and inserted it again and now it started to behave correctly starting from 1%.
Another thing I have noticed is that when it reaches 100% it starts to discharge until it goes down to 95% then it charges again (quite normal behavior) but the phone still shows 100%. So it could be down at 95% when you disconnect it but it starts to tick down from 100%. I did check the kernel source and it was a comment there that it should show 100% while still charging in that mode.
It's possible to see the real value when using adb logcat|grep charge and also betterbatterystats shows the real value instead of the 100%.
thanks for the tip will try that. i get that same thing too, dies at 30% but when charged, it goes up at 30% immediately hehe... well, i didn't went to extent remove the battery though. what i do know is to have "Battery Monitor" sound some notification at 3425mA. At that rating, that just means I have some time to look for the cable and charge it.
Side by side, the st15i screen is significantly brighter than the st18i screen at the same brightness level. Though the st18i has a higher resolution, its colors appear more washed out, in a way though that is easy on the eyes. The st15i seems to be brighter and perhaps that is hurting the battery life.
Upon further testing, it appears the auto brightness feature of the stock rom is doing this.
With both devices in a dark environment, the st18i appeared brighter, with the same brightness settings.
Unfortunately, there doesnt seem to be a way to turn off auto brightness on the stock rom.
My mini pro's battery last much longer then it did on my old phone galaxy s2 so I have not a problem with battery

how long does it take for your mini-pro to fully charge when is on?
2 hours and i have 13% from dead and i on to charge it.. i killed all apps...
This there something wrong?

I'm currently on almost 2 days since charge and on 8%. And just when I started writing this it did just go down to 1% and a warning that battery is almost dead.
So it become 2% "better" ;-)
But I'm still happy with almost 2d with mixed usage and standby (wifi,push etc all the time).
THIS THREAD IS FOR ALL QUESTIONS AND ANSWERS WHICH HAS NOTHING TO DO WITH DEVELOPEMENT!!!
I think about 50% of the Post´s in Lees Developement Thread are irrelevant vor him. A Developement Thread is for bugreport, for things which doesnt work, ....
And not for: "When is the next release?" "Can you please include this and this ..." "A third parts app is not working" ...... and so on and so on!
Its Lee´s Rom and its his joice what he will include and what not!
So please Guys post here and keep the Developement Thread clean!!!!!

Can someone confirm, that without the dual core scripts the 2nd core never kicks in? The normal behaviour should be that the 2nd core kicks in when the first core is stressed, e.g. setcpu stress test ore playing a 3D game.
Lee confirmed, that he configured the second core to be not so sensible..and said that he will have a look at the config again.
I think the behaviour of the second core is controlled in the system/bin/mpdecision file...I changed it with one of a Evo 3D cdma rom,after that i saw the first time that my second core kicks in in system tuner, it turned on/off several times - altough it shouldn't be needed.
i think the standard config is too sensible, so it was a good move from lee to lower it - but I think now with the current config it seems that the second core is completly turned off =D
Yep i can confirm! My second score never kicks in! Ive flashed the ondemand patch from first post and undervolted -100 and love the battery life now!

...I don't like the behaviour, that the second core is always on - not very battery friendly
Hope Lee will fix this issue in the next release - hopefully he will use the new base which is flaoting around the gsm forums.

Yeah i know but battery life for my usage is ok! But i know dat right. I really miss 3 days of battery life with my Nexus S! But i know the kernels getting better and better
what do you guys use to change the volt with lee's kernel ?
I am having huge battery drain and cant figure out what it is!?
getting about 100-300 mA in standby 90% of the time and an everything from 450 - 950 mA while using the phone, some times I don't even use any load on the cpu but it still peaks to 900 mA
I am carefully watching a cpu notification while using the phone and it draws usually 300+ mA with max 10 % cpu load with interactive governor
I tried downclock to 192MHz and disabling second core (since it never enables with lee's new rom) and it still uses the exact same mA. so downclock and disabling doesnt help the powerdrain at all
what to do ? just lost about 10 % by 15 minutes of standby !?
my only thought was that the cpu was giving the same voltage no matter what the frequency is, so if there is any app that could change the volt ?
have any of you had huge power drain ? could anyone try to check how much mA your evo uses in standby with the new kernel and rom ?

dont trust the ma values, for me all battery apps are showing 200+ in standby. htc delivers crappy weird ma values and theirs no way to fix that. The dev if battery monitor can confirm that.
...im loosing 1% over night.
Try to reinstall rom without third party app. Are you using htc Mail with exchange - it got a bug which keeps your device awake when in airplane mode.
Theres also an app in the market, where you can check if your phone goes to standby or not..srx dont remember the name - Google it

well have you tried "battery Monitor widget pro" thats the one I am using, it has an fix for evo 3d to fix mA drain
problem is that I calculated the drain by just simple math and it confirms the mA drain ;/ so the program does really appear to be correct
maybe some one else could try "battery Monitor widget pro" and see if they are experiencing the same mA drain with this program ?
but the strange thing is that it wasnt draining so much before the kernel update and rom, and some times it goes down to normal usage but happens rarely
I do not use mail exchange, going to check for the standby program though and try to reinstall without any apps ! thanks for the suggestion

Yeah, know this app but its not working for me, still shows >200 during screen off also with the special evo 3d fix.
..searched about 30 min to find that app:
Cpu spy from market.
it shows you how long your device is on which frequencies or in deep sleep.
Reset the values in the menu and turn your device off. After a minute check the values.
Sent from my HTC EVO 3D X515m using xda premium
I just tested the cpu spy, and I had the screen off for 5 min, and only deep state was counted, said 90% (5 min)
And 30 second on 192mhz
Seems to be right?
yeah, should be fine. And yourre sure, that you lost 10% of battery in 15min of standby? Try calibrating your battery with battery calibration from market.
charge to 100% and then calibrate.
yes 100 % sure but i wass messing with the the frequency of the cpu , might be what drained the power because today it has been normal standby time
already used battery calibrating, it did get a little better in standby after that.
but i still have huge power drain by just turning on the screen, and typing
i had just sent a couple of messages through "messenger for facebook" throught an hour and it used 20 % battery and I only turned on the screen, unlocked it typed a fast short messages and turned the screen off again a couple of times
I was connected with Edge all the time (gsm) since 3G was turned off to save battery but still huge power drain.
I just feel like every time the screen is on the % start falling fast :s
thats why I wanted to check out undervolting but cant find a app that supports lee's kernel

Use System Tuner from 3c (same dev as battery monitor) to undervolt.
Easy as hell
Haha thanks, lol I had an old version of system tuner that's why I didn't have any voltage control
Seems like my battery life is a bit more normal now, thanks for all the help and time you spent!

Maybe Edge is the problem for your battery-drain! When my Evo is on Edge it needs way more battery as with 3g!
And try to disable "automatic display light" (no plan how it is called in english). I always use the second stage from 4... i hope you know what i mean!

Well I did notice that edge drain at least as much as 3g so no point at disabling 3g, I got my battery a little more stable but still use Huge power drain sometimes
But going to reinstall everything, do a clean wipe and stuff and install only the apps I use not all the cap I got now.
Maybe that will help a bit on the battery
still questioning the LeeDrOiD rom for battery life.
I love the rom but miss battery life, sense 3.5 and the new Android version 4(i know the new android version isn't released for htc evo 3d yet though) but really looking forward to it!
Don't know if anyone else has played with it, but if i need a FAST charge and i can afford to do it, i use setcpu to turn the max CPU as low as it will go, which is 216mhz and let the phone charge.
I am using Battery Circle on the stock moto ROM with as much blur removed as i can, and if i let it sit with this CPU speed forced, i will see it go from 20-80% in as little as an HOUR...
restarting the phone with the battery bug can get me even higher, maybe upper 80% on the battery.
Try it, it really works! I have played with a profile that sets it as soon as the charger is plugged in to around 400mhz but the phone i find lags and it is hard to use, so i just plug, launch the setcpu app and crank down to 216hz
when i am done i unlock the phone, and put the speed back to where ever i need it to be.
Wouldn't powering down the phone while charging achieve the same results?
I've had a lot of problems with cranking the cpu speed down to the minimum -- a lot of laggy performance and some lockups that required a battery yank. In fact I use setcpu to force the minimum speed on my phone to 456 MHz to avoid any such problems.

It really depends on a few things.
Your launcher, what the phone is trying to do while idle, etc.
Example, i find that if i have a lockscreen pattern that needs to be drawn i will have to be patient with it.
and obviously powering down the phone works.
It also makes it so your calls go straight to voicemail and you miss all sms messages.
I use my phone for business and i cannot have that problem, so long as i use fast reboot to "wipe" things out once in a while nothing bothers me putting the speed down.
You can charge lower, around 500mhz.. it also helps.
I think it has to do with the voltage being used to power the CPU being very low that helps it charge so much faster.
My P760 is heating in the sim card area with almost no use, the battery doesn't get hotter then 38C.
Is this normal?

No, as far as I know there is CPU somewhere nearby and that causes heat. What CPU governon you have? If "performance" you should change it. Also maybe some apps working cause high use of CPU? There can be a lot of reasons. You have to tell us more details such as ROM which you use, if this thing happened from the start etc. For start you can try hard reset and see how it will work.

And if I integrated some app updates into rom, can I use hard reset?

So can I hard reset if I integrated apps into rom?
You can but you will lose them. You will need reinstall them.

So how long it stays in 1000 Mhz? Did you try different governon?
8 hours on battery. 37% battery. 37 min at 300mhz. 1h at 600mhz. 9min at 800mhz. 32min at 1ghz. 5h 34min deep sleep. All of these with hotplug governer.

It look everything is fine. Well the last resort is to give your phone to LG service if noone else will write something but I wouldn't bother if it's only heat. My phone sometimes heats up if I watch a lot of videos or something but not in normal use as listening music or surfing in the net so it's still strange.
It start warming fast and it fills like a cold spot. Warm middle cold outise. Also if I tap the back of the phone I can hear a sound like a jingle or a spring.
I have changed my device and this one has the same symptoms. I think that this is a fabrication issue. It is happening also for Nexus 4 (made by LG too). http://code.google.com/p/android/issues/detail?id=40334

Hello,
I got a battery issue on my Samsung Galaxy Core Prime for at least more than a year.
The problem is: almost everytime, my phone crash when arround 40% battery level. It's not an informatic crash but... I'm not sure. The phone just suddenly shut down, not as it ran out of battery, displaying the shutdown logo and going to sleep, it behave like I pulled off the battery.
This is not a battery misplacement problem because the shutdown doesn't happen a totally random way: it never triggered over 50% for now.
Moreover, the battery level goes wrong after such crash. Even after waiting some time with battery out of phone I got randomly a new battery percentage that will be either lower, same or even higher than when it crashed. So maybe the whole problem is due to a shift between real battery percentage and what phone determined.
I also noticed that when rebooting after the crash the phone speakers make a weird sound, a kind of "shhhhhhhh" even with silent mode enabled and no system sound, and when it happens phone recrash on booting (system) logo.
I personally don't think it's system's fault, because between the first time it happened and now I may have flashed at least 6 times my ROM and made various wipes. Also somebody getting the same phone model than me never got such problem, even tough he is not rooted and has recent firmware. In the end the problem getting worse and worse again (=more frequent) so I'm almost sure it's a material problem.
But which one? Is this directly battery's fault or is it captor's fault? Actually I threatened the battery very badly, it's true. But everything I did — overcharging, emptying battery at the time I thought that was a good thing because of a suppoesed memory effect like nickel batteries, using charger block from an older device with a bit different configuration — should have shortened the battery's life, however it's just like the battery is now discharging a bit faster but got a kind of danger zone where you're not sure that it will keep behaving normally, so much that some measurements and developing apps determined that my battery have a good health, that is maybe absolutely FALSE.
Talking about this danger zone, I also noticed something even stranger over all.
Depending of what I do, I got higher or lower chance to have my phone crashing under 40% level:
- If Wifi is enabled, the phone got arround a half more chance to shut down unexpectedly.
- This is worse when using data consuming app (i.e. Youtube)
- Using more hardware also increase this phenomenon (when using camera) and enabling flash instantaneously and almost everytime crash the phone.
Here are what I reported.
What do you think?
It has happened to me many times. So i normally keep it charging all the time to be safe.

All the time for real? Be careful, that's not a good practice. Unless you removed the battery first, this will get worse if you do that.
I have a similar but possibly unrelated problem.
If i charge upto 100%, the battery goes directly to 0 after around 50%.
If i charge upto 50%, then the battery drains rapidly after around 20%.
I don't think its a battery problem because its the same with two replacement batteries and a stock battery. (Or maybe I have a bad luck and bought ****ty batteries)
Will post a screenshot soon...
I have the Same problem i changed the battery twice but i still have the issue

What you posted is close to what I noticed, so it is not unrelated.
This is weird that after buying two more batteries the issue still occure...
I've this problem too :/ (G361H)
I have this problem too. This is the batteries fault only.

Hello,
I got a battery issue on my Samsung Galaxy Core Prime for at least more than a year.
The problem is: almost everytime, my phone crash when arround 40% battery level. It's not an informatic crash but... I'm not sure. The phone just suddenly shut down, not as it ran out of battery, displaying the shutdown logo and going to sleep, it behave like I pulled off the battery.
This is not a battery misplacement problem because the shutdown doesn't happen a totally random way: it never triggered over 50% for now.
Moreover, the battery level goes wrong after such crash. Even after waiting some time with battery out of phone I got randomly a new battery percentage that will be either lower, same or even higher than when it crashed. So maybe the whole problem is due to a shift between real battery percentage and what phone determined.
I also noticed that when rebooting after the crash the phone speakers make a weird sound, a kind of "shhhhhhhh" even with silent mode enabled and no system sound, and when it happens phone recrash on booting (system) logo.
I personally don't think it's system's fault, because between the first time it happened and now I may have flashed at least 6 times my ROM and made various wipes. Also somebody getting the same phone model than me never got such problem, even tough he is not rooted and has recent firmware. In the end the problem getting worse and worse again (=more frequent) so I'm almost sure it's a material problem.
But which one? Is this directly battery's fault or is it captor's fault? Actually I threatened the battery very badly, it's true. But everything I did — overcharging, emptying battery at the time I thought that was a good thing because of a suppoesed memory effect like nickel batteries, using charger block from an older device with a bit different configuration — should have shortened the battery's life, however it's just like the battery is now discharging a bit faster but got a kind of danger zone where you're not sure that it will keep behaving normally, so much that some measurements and developing apps determined that my battery have a good health, that is maybe absolutely FALSE.
Talking about this danger zone, I also noticed something even stranger over all.

My device goes at 60%, 40%, etc. and then it starts repedeatly pressing the right side of my screen and not letting me tap the screen, so I lock it and unlock it very fast and I can use the touchscreen for a few moments, before it shuts down without the shutdown screen and makes a *tick* sound, almost like there was an electrical shock inside the battery. I have a PRF and TWRP 2.8.7.0.

Got exactly the same problem. You can try to change the battery but in my opinion the only good solution would be to buy another phone. This is personally what I did, as this model gets old really early.

I have this same exact problem and the only fixes according to me is to buy a new phone or replace the battery. Also I noticed that the battery of my device has bulged.
RIP, I have the SM-G360T1, stock based custom ROM with TWRP 3.0.1 and this thing's started to give up. Same issues as the people above encountered. The phantom touches are getting wayyy more repetitive, the battery all of a sudden goes down to an extremely low percentage, even at medium to high percentages (such as 50-60%) and even shuts off without any notification. I also had cases where the phone would completely turn off with no shutdown animation AT ALL, plus a spontaneous but audible *TICK* that follows it. Device performance in general also started to horribly depreciate.
Well, to be fair, I had this device for 3 years and I guess it had its day. Time to upgrade.
My device has started to shut off at 80% battery levels and even worse the device gives just about 25-30 min of SOT. Also stressing the device in any way.. games, YouTube et al just causes it to shut down. I now permanently have a battery pack connected to it at all times. But even after all this, the gives good standby time. Notably the device stand for 3+hrs on 3% battery.
Still my phone is in a pathetic condition. ?
Edit - I just got a new battery (aftermarket brand though) and the ghost touches along with sudden shutdown has gone. Also the OG battery was never touching the connectors properly or the battery placement design was not proper, cause the new aftermarket battery was not connected to the connectors properly.
Peace ?
i also got this problem on my sm-g360HU , try chaging different roms and buying a new battery pack, but still this sudden drain battery still exist, it seems like it's the hardware problem already.
