Hi there guys,
I was just wondering if it's possible to enable the GS3 to switch over to power saving mode hits a certain battery percentage. If I'm not mistaken my sister's GS2 has this option in her settings.
Would really be a bit of a life saver for me as I don't seem to be getting the best battery performance on the phone (needs a daily recharge under light-moderate use).

Hi All,
After googling lot on improving the battery life.. I found many ways to improve the battery life. Sharing it with you..
1. Use Auto Killers - Kill all the background processes. *
2. Use in Aeroplane Mode - while you are in out of signal area. ****
3. UnderClocking - Apps available like setCPU, OverClockWidget, cpuTuner.. sets the clock frequency to lower values when screen is off. ****
4. Undervolting - make processor to work below the standard voltage. This is kernel level configuration.. not sure how to implement..
5. Use a powerful battery - there are some batteries with more mAh which last longer. ***
6. Proper Charging - ****
turn off the phone, plug it in, preferably overnight.
boot the phone up while still plugged in.
delete the batterystats.bin file ether through adb, Root Explorer or terminal
drain the battery fully, until it powers down. wait a min or two and reboot it to completely drain it.
then your phone now knows correct voltage values for 100% and dead.
Remember: Flashing a new Android build erases the battery stats, and automatically rebuilds them based on voltages it see's.so must recondition after each flash to get max battery life.
Please Reshare your view and observation...
I was out of WCDMA range for a week over Christmas (just GSM network available) and using my phone with Wifi and a bit of Bluetooth Audio (and even a bit of angry birds!) The battery lasted for.. wait for it..
5days, 3h, 27min 29sec (I put it on Charge at 23% capacity!!) so I think I could have got 6 or even 7 days out of it (not that I would let the battery get that low on purpose)!
must be some kind of record!
and in reply to the above post about discharging the battery.... (I don't want to bore people on here with another one of my Li-po Battery care rants so I will keep it short this time)
I wouldn't recommend discharging Li-Po batteries too often, they hate it and it can significantly reduce the over all life of the battery (which would suck for the mini) I say leave the charging up to the phone and just top up regularly using a low Amp charger (USB is good or other 500mA charger, I feel the 850mA charger that came with the phone is a bit over powered) try not to let the phone discharge until it shuts off (this is triggering a safety switch to protect the battery from damage, and its not good for it)
That is all.. carry on.
whats battery duration for x10 mini pro?
with a normal / litle intensive usage, my battery must be charged every day.
Is this normal?

I usually get 2 or 3 days. On days that I skype, I have to recharge. It depends a lot on usage. I guess that, if you don't use the smartphone capabilities, you will get an even longer battery time.
More info about the battery on the wiki.
I was just rereading the comment of kiwi braad worst, and he might have a good point on using a low amp charger. I mostly use the charger from the usb. When I use the charger that came with the phone (850mA) I get less battery. Though, that could be placebo effect.

My experience with the X10 Mini (not PRO) is that the battery life gets better over time. It's worth discharging and recharging the battery fully a couple of times and then resuming a 'normal' charge routine - let it drop below 20 or 15% and charge it until it's 80%+ charged. When I first got my phone it needed a charge every day. Now it needs one every three or more on average. I've also found that turning off the 3G aerial (allowing GSM only) and manually selecting the network operator (preventing regular polling) helped extend the time between recharges. There are widgets available that will allow quick access to those functions when needed. I will say that I'm not an 'always-on' kinda user. It's mostly a phone/music player to me, but once or twice a day I check email, browse web etc
Try Juice Defender
The two biggest things on my battery use is the display and the cell standby.
So the best way to save battery would be not to use it that often....
sucks but that is pretty much the truth about it.

I Turned the brightness down and that gave me abit extra.
One very good way to save battery power is to disable vibration if possible. Vibration uses two times more battery power than ringtones due to the low frequency required by the speaker. Disable vibration and save batter power.
Use an application that can edit cpufreq, like Overclock Widget and SetCPU to reduce battery power when screen turns off
Overclock widget can set different cpu max and min speeds for when screen turned on or off.
Battery Diviner can record patterns in battery usage and change performance according to your usage.
Hello all....this strange thing I have noticed in the last few months....I used to keep the power saving mode enabled....and every time by afternoon my battery will fall below 30% which I have kept as the threshold. In the last two weeks I have disabled the power saving mode and I have a longer battery life....now I only have to put it for charge at night!
Anybody having this same issue!!!!
Lol, congratulation XD
If you're using a custom ROM, probably the kernel governor handles battery better than the stock saving mode from Samsung.
power saving mode also uses battery as it periodically wakes the phone to check the battery level when sleeping.
Enable it if you are a heavy user and need warning when the phone battery level falls below a certain level.
I have the stock rom...still not gone into rooting or custom roms
I'm curious, since my new Note has been inhaling battery life... Has been since I got it and there were only the basic apps. I can't even charge it up while using it (the indicator declines even on wall power if I'm browsing or sketching with the screen on one tick from lowest brightness).
Anyway, I have Juice Defender and Battery Widget 1x1... Was thinking of adding Badass Battery Monitor but wonder if these running apps cause harm as well as help?
I have i717 AT&T updated stock ICS rooted. I set the device in Power Saving mode to kick in at 50% battery life. Once it hits the 50% battery life mark it displays a notification window saying "Battery level below 50%. Power saving will run. Continue?" It seems this notification pops up almost every time I bring the phone out of rest mode (clicking power button to turn on the screen's lockscreen). It alerts me many times.
It's incredibly annoying when my phone alarm wakes me up in the morning and I'm reaching over to try to slide my finger over the screen to shut off the alarm, but it won't do anything because the damn power saving mode notification window is up and waiting for me to press OK or CANCEL.
Can I disable this notification? I can't find the area to make this setting.
I also looked at installed apps and don't see anything that resembles Power Saving Mode to see if there are any settings I can make through ROMToolbox.
Is this something I can try to disable through Tasker?
Can anyone please advise?
Why is your battery below half first thing in the morning?
You could charge it overnight then the battery will be full when your alarm goes off.
Otherwise to turn off that notification will take some editing of the rom.
That notification is there because power saving mode under clocks the cpu amongst other things that sacrifice performance for battery life... if when you want to unlock the device and run it full speed for just a couple minutes you hit cancel on that notification... or ok to run at the throttled specs of power saving mode.
I played around with power saving mode when I first got the note and noticed that any power saved by the throttling was wasted by me waiting on it with the screen on lol . So I just bought a second battery and external charger.
I am of the old school of "rechargeable batteries" where I let the battery drain to near 100% before charging again, and when I have it plugged in for charging I let it get 100% before disconnecting. I don't know if the batteries today don't have the problem of losing its lifespan due to incomplete charge sessions.
I get about 48hrs between charges with the workload I put on the device...NOT a phone gamer or constant "feelings" updater on facebook.
Studacris (I feel odd saying that) - mind if I pass an issue by you for your opinion?

I'm reply #7 - I thought I found the issue of my default ringtone/notification sound resetting to default all the time...but it JUST happened again.
Advise?
The chemistry in batteries nowadays is much improved as well as software for charging:
True a battery does have a finite amount of charge cycles, however a charge cycle doesn't count add each time it's plugged in, it's each time a full 100% charge and drain have occurred:
drain halfway, charge full, drain half, charge= 1 cycle and so forth.
Furthermore overcharging isn't possible. android stops charging at full and the lets the battery sip on 1% for a while then starts charging eventually once needed.
And with such a low cost for a replacement battery it really isn't much to worry about.
My x10 is losing all of its juice in maximum of 5 hours , I've bought a new battery from SE showroom but the brand new battery is also giving me the same bitter taste ..... I have tried various ROMs and presently flashed my fave ROM DONUT HD2 ROM based on GB......I also flashed stock GB 2.3 with new batterty but the same battery issue is noticed.
Its music port also stopped working from the day im experiencing this battery issue.
I calibrated the batteries , but also NO use.
In battery stats it shows that the maximum battery consumption is for Display and Cell Standbuy. NOW I have no idea what the hell is my phone problem , but i love it , so wanna fix it ANYWAY.
Please suggest me your valuable ideas.

What screen display timeout do you have? I have mine set to 2minutes.
What screen brightness do you have? I have mine set to the lowest setting as I'm indoors mostly.
However, it doesn't really matter if you have a short screen timeout.
Do you have 3G mobile data, Wifi, Bluetooth, GPS and Google Maps with Latitude/location tracking all turned on?
The battery can be drained in low/poor mobile cell areas.
The phone boosts the receiver to get a signal which all takes power.
If you have no or very poor 3G mobile data signal, it'd be best to disable 3G mobile data when in poor signal area(s).
In the battery History display (Settings->About->battery use), tap on the graph to display battery status.
This will show you the signal strength of the battery over the time from the last full charge.
If the phone signal strength indicates red/yellowish that's not good, dark grey/green is good.
A new battery should be charged to 100% and left to continue charging for approx 8-12 hours.
The charging cuts out at 100% and then drops back to ~93% and then charges again.
Leaving it for 8-12 hours on the first 4-5 charges help the battery find it's maximum charge.
Any new battery may not provide it's maximum charge for the first 4-5 charges.
I found Google Play Store GSam Battery Monitor a very good indicator of process and battery usage. Also shows percentage of cell signal strength state.
Look for "View time held awake" and "View number of times waking device" in the applications section.
If you have root access, you can run something like Google Play Store SetCPU and have a screen-off profile which can under-clock the CPU when the screen is not on. Using a Powersave Governor can massively improve battery life when the phone is in standby state and/or not in use.
You can use Google Play Store CPU Spy Plus to verify that when the screen is off the phone is going into 'deep sleep' for most of the time.
I get approx 60-70% of the time spent in 'Deep Sleep'.
I know on my 1800mAh battery in my XPERIA X10i gets 3hrs 17mins when CPU is at 100% and screen on 100% brightness, with 19% of the battery still left.
In 'normal' operation I get from 1 - 5 days of battery life.
I have had 10 days when I didn't use the phone, with WiFi forced active at 8:00am once a day and email(5 accounts), whatsApp and weather widget active.
In 24hr period when not using my phone, it uses approx 7-9% of battery(1800mAh).
should CPU rate decreased????
THANKS for your REPLY
I set my Network Mode to ONLY GSM , switched OFF location services (GPS,Maps,G altitude,etc etc) and my screen Brightness is ZERO , time out is 30 seconds. And i've been living in the same place since 3 years and it is not the problem of the network.
From your suggestions it is clear that , we (x10 users) should not use x10's at 100% CPU.I should NOW try this.
I got a 1500mAh battery in the box when I bought my x10 and the battery I bought when i messed up with old battery (I thought that the old one is damaged) ) was also a same 1500mAh battery.
The apps(EXCEPT GSAM battery Monitor) you have suggested me were also used by me in the past and Im actually fedup with the battery.
Now i will try to underclock the CPU rates at screen OFF mode and use GSAM battery monitor App.
ONCE AGAIN THANKS FOR YOUR REPLY.

The 100% CPU was an AnTuTu battery stress test know as Google Play Store AnTuTu Tester
This tests the battery use from 100% down to ~20%, calculating how long it would last.
Using a 1500mAh battery the AnTuTu Tester should return approx 2hrs 45mins on a battery operating at the same capacity as my 1800mAh battery.
I still really enjoy my XPERIA X10i and use it daily, probably helped by the fact I have a 64GB SanDisk Ultra card in it.
