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.
Hi all,
I'm rooted, S-Off and on Honeycomb with the revolutionary method with CWM and all is working great and has been for over a month now.
I'm just worried regarding the battery. I've seen snippets of info that if the battery fully discharges, i'm screwed.
can anyone please confirm that it is either OK or NOT OK to let the battery run down on the Flyer?
thanks,
Yes, if Li-ion batteries are actually drained to zero voltage, they are useless. However, technically, there are safety measures both in the battery itself (safety circuit) and the device that protect the battery from complete discharge. The device will tell you that zero battery is left, and shutdown. So in most instances, you are protected.
HOWEVER, I have seen plenty of cases on Android devices (and older phones, such as Windows Mobile) where the safety measures don't always kick in properly. People will let there phone/device drain until it shuts off, then they can't get it recharged. In these cases, the voltage is still not actually zero. But if the voltage is below a certain threshold, it won't take a charge from the normal charger. Only way to bring these batteries back, is a special battery meter with a boost function. Or replace the battery. As most of us don't have access to such a meter (and might not help anyway, since the battery is not designed to be removable) you're pretty well screwed.
This doesn't happen often. But if it happens to you, yes you are screwed.
Another thing about full discharge cycles on a Li-ion battery, is that it will shorten the life of the battery in the long term.
Moral of the story, is don't drain the battery to zero intentionally or often. Some people do it to calibrate the battery meter. This is worthless, as the battery meter on phones and tablets are not accurate enough to justify running the battery until the device shuts down. Just drain to 10 or even 20%, recharge to full (leave it there a while) and repeat a couple times, if you want to calibrate the battery meter.
As for normal usage, avoid draining the battery until shutdown. Its fine if it happens accidentally once in a while, we've all done it. But don't let it happen frequently.
How can I maximise the battery performance?
There are a few things you can do to improve the battery performance.
Charge your phone often. This will not affect the lifetime of the battery.

this is what they say on their official web site,does this mean that when we charge it more often battery will perform better or what? I mean abouth batter lifetime will it make longer or just same?

As it says, it won't affect the lifetime in any way. So not better but not worse.
Charge often. Even better wait till low batt and charge. The calibration software will average it out and it will start improving. If it is not calibrated properly the phone will show low bat quickly. I had a phone showing 1% charge for over 2 hours and not die.
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.

I'm interested in the greenify app, the only problem is that it does not support stock gingerbread which can give the most juice. Do you have any other recommendations of similar apps?

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!

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.
I am seeing too many battery misconceptions. Let me clear them up.
STORAGE:
Lithium batteries like to sit around 50% for prolonged periods. If you need to power down your phone and store it, do it around 50-60%.
STATE OF CHAGE / BATTERY LEVEL
- It will NOT hurt to keep your phone on the charger. The charging circuitry cuts off power once the Cell hits 4.35 - 4.4v (If it did not, your battery would swell and heat up and then explode or catch on fire or both)
- It is MUCH more harmful to deplete the battery than it is to keep it full. Lithium batteries DO NOT like to go below a certain voltage depending on specific chemistry formulation.
For Example: Chevy Volt electric car Lithium battery is set to stay within 30% - 80%. They are limited to never exceed an SOC of 80% and never go below 30%. Source: https://en.wikipedia.org/wiki/Chevrolet_Volt
To expand on this. It is BETTER to keep the phone at 95% than it is to keep it at 5% for example. I personally would NOT want my battery falling low enough that it gives a low battery indication (usually around 15%). Usually I do not want it hitting 30%. That's a good rule imho.
CHARGE AND DISCHARGE CURRENT
Lithium batteries prefer to be charged slowly and discharged slowly. They do NOT like high charge and drain.
You guessed it. AVOID high charge scenarios such as Fast Charge. AVOID fast discharge scenarios such as gaming with high brightness etc.
TEMPRATURE
Lithium batteries do not like getting hot. They don't even like getting warm. Getting hot hurts it. Getting warm isn't as bad but it DOES degrade the total capacity over time.
Again, this is usually caused due to high charge or discharge scenarios.
It also ties in with Fast charge, wireless charge and especially wireless fast charge. Wireless charging is not efficient and energy as wasted as heat.
Personally I disable fast charge and do not use wireless charging. Good old USB Type C already charges quickly enough for me.
TLDR: Disable Fast Charge. Try to use USB Type C charging instead of wireless charging. Disable stuff you don't actually use. Try to keep power save on even if using it with very little power saving settings. Try to keep brightness at a reasonable level and not too high (This reduces AMOLED degradation too).
Remember: THE BATTERY IS NOT EASILY REPLACEABLE IN THE NOTE 7 !!!!!!!! Therefore the more you baby it, the longer it will hold it's charge and the lower the chance of the battery going bad.
My old Notes (Note 2 and Note 4) both still have VERY good original batteries because they were well taken of.
Good luck !
But I like fast charging and wireless charging lol
Ironic that when your phone is new, this is when the battery gets hot and used a lot. Perhaps with the water resistant phones we should update the firmware and restore the backup under water to keep the phone cool!
I will be sure to disregard just about everything in here. Guy is spreading false panic.
Actually "store mode" example: found in 7420 kernel source is 60-70% capacity. There are a lot of checks within source including battery swell etc. Don't fret about things, use your device. It's not as delicate as you may think. Who cares about the efficiency of wireless charging. Great if you've got it
90% won't keep beyond 2 years, just enjoy the thing !!
