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

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.
What is everyone's battery life on this phone? 55 minutes in with light use I'm down to 75%
My phone is rooted so not sure if that matters, waiting on someone to allow LTE to be switched off

I haven't done any objective tests (too busy playing with it) but mine has been great. I'm rooted and overclocked. I've enabled the lowest power stepping, my battery power has been phenomenonal and getting better. Inverted apps, dark themes, great deep idle and a massive stock battery I fully expect the g -note to shape up as a new standard in phone battery life.
You've must have something, a background service, something like that, and it is chewing up your electrons. Have you checked your battery stats? If you can't find a power thief return it, or at least exchange the battery. With millions of batteries there has got to be a few bad ones. Until then, can you post a battery usage graph?

I've always found it wise to run the battery to full charge/complete discharge a time or two to calibrate the battery
When I got my skyrocket new, I drained the battery down to 20% in 5 hours, then it took another 5 hours to drain that. Afterwards, the battery "appeared" to last longer. Today is my "kill the battery" day.
I've always read the Li-Ion batteries work best at 40% capacity. Not sure why, but I would think that the meter is highly inaccurate at the upper and lower ends of the readings.
I have seen lots of threads about people complaining about very poor battery life after flashing roms. Sometimes battery charges to 100% quickly and discharges very quickly.
So, these are the solutions. These solutions are IN ORDER. If the first one has no effect, then try the next one. If the second one doesn't work, then try the third one.
Now-
1) Try reflashing your ROM.
2) If reflashing your current ROM doesn't work, that probably means the ROM itself has poor battery life and you should change it. Stock ROM's have the best battery life.
3) If you are on stock ROM and still having problems, switch off your phone, take off the back cover and remove the battery. If the battery is swollen or the shaped weirdly, this means your battery is dead and almost useless. You need to buy a new one.
I recommend buying only stock batteries manufactured by Samsung because other batteries can be fake, incompatible, or just used batteries sold to you. Don't buy anything else unless you're absolutely sure of what you're doing.
Hopefully I helped.

General tips for saving your battery-
1) Switch off mobile data whenever you're not using the internet.
2) Change your wifi sleep policy. This can be done by going to wifi settings, pressing menu button and then select advanced.
You can change your sleep policy so that your wifi sleeps when the screen is off.
3) Decrease your brightness! Your screen is responsible for most of the battery drain. Increase your brightness only when you are in bright sunlight or when you're watching videos etc.
4) Switch off GPS. Keeping it on all the time also drains a lot of battery.
5) There is an app called 'Greenify' which hibernates the apps running in the background. This app has increased my battery life. Here a link https://play.google.com/store/apps/...e=google&utm_medium=organic&utm_term=greenify
6) Don't charge your phone when it's at 70%. Wait till it is between 20-30% and then charge it continuously till it reaches 100%.
7) Let your battery completely discharge once every month.
8) Don't use task killers. They use more battery life than they save.
9) NEVER charge your phone overnight. Your phone takes only about 4 hours to charge. Overcharging reduces your battery life
10) If you use a Bluetooth headset, switch off Bluetooth whenever not in use.
11) Using setCPU profiles. This is one of the most effective ways of saving battery. You all know about overclocking, but do you know about underclocking or undervolting? Using profiles, You decrease the clock speed of your CPU when certain conditions are met. These profiles can be on the basis of time, screen off/on, battery etc. So when my screen is off, it automatically reduces the clockspeed which saves battery

Using these tips, I have gotten almost 2 days of battery life on stock Roms and a whole day of battery life on custom roms like CM10.1 and CM7
If you have your own battery saving tips, please share and help expand this list.

Are you sure about these? Because I've read that phones only take how much ever charge that they need, so charging overnight isn't a problem. And i've also heard that letting the battery charge fall below 40% actually reduces the life over time.

Yes, I am sure and it is something I have verified.
Overcharging kills the battery.
I saw a video once of an evo 3d. The battery almost completely died after it was charged for 3 days
And you should always charge only when your battery is low.
This will ensure longer battery life

Normally, when the battery is fully charged, the chip that controls the charging process reduce the current exponentially to 0: this avoid the overcharging.
I think all smartphones have the charging chip control integrated (an USB cable is simply a power source, not a battery charger), so I hope we can leave the phones on charge all the night without any problem. I do that always and never had problems.

Well, if you see again, I never mentioned that clearing battery stats saves battery. It is for those people whose phone charges very quickly with big increments, which typically happens after changing ROM's.

Quoting Dianne Hacborn(Android Framework Engineer):
"Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away."
Its just a myth mate..
And also, it's a myth that you should let ur phone charge reach 10% or get fully discharged before charging. This actually leads to decrease in the battery life over time.

Think of your battery as a person working out and charging is like taking rest. If the person's ability is to do 100 reps yet he takes rest after only 60 reps and keeps doing that continuously, he won't be able to do 100 reps after a few weeks!
Look at the logic mate.

Clearing battery stats does not:

Affect the battery level displayed to you
The only thing it does is, it wipes the history of battery consumption by each app. I am talking about the battery consumption by each app shown to you in Settings>About phone. If you clear the battery stats.bin file, the only thing that geta erased is this

This! Anything about wiping battery stats is not a myth anymore, so please stop misleading people,
Also "6) Don't charge your phone when it's at 40%. Wait till is below 10% and then charge it continuously till it reaches 100%."
Not true! Charging your battery around 50% is the most efficient way to keep lithium battery alive longer. A discharge once a month is also recommended.
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.
This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.
