This is very helpful. Thanks button clicked.

I also found that when I installed a femtocell, and now booster for tmobile, my batteries lasted about 50%ish longer. I wish I had before and after data. Anyway, it made a significant difference since the phone didn't have to ping the tower at full power.

Tips for Saving Battery:

*I don't take any responsibility if anything terrible happens to your phone. If you point your fingers at me I will just laugh at you.

- Turn off the Wi-Fi/WLAN of your phone

- Turn off the Bluetooth

- Turn off the GPS

- Disable the Account Auto-Sync (if you have an Android Phone)

- Turn down/Lower the Brightness of the Display (if you have an Android Phone)

- Leave your phone charged when going to sleep (it will have a good battery backup)

- Delete the "batterystats.bin" (if you have an Android Phone)

- If you are an Advance User, you may also consider UNDERCLOCKING your phone :rolleyes:

like where to get a kernel that allows undervolting?

does cf-root support it?
[General Topics] prince9030:
hopefully it helps me out
[General Topics] Xenova:
I wish to. But the kernel for every phone is different and it is also depend on the version of ROM base. Thus, it is best for the users to refer to their respective thread.

One question. Leaving the battery on charge for the whole night is safe and good for the battery?

time to look for a kernel that has undervoltage.

What about juice defender?
[General Topics] chrcol:
ok I will install the app, hopefully it will detect if my cf-root can do it or not.

is it harmless changing a setting when kernel doesnt support it?
[General Topics] Xenova:
It's safe. The battery has circuit that automatically cut off the current when it is fully charged. That's why it is important to use original battery and charger that have quality assured
[General Topics] Xenova:
It's a useful app if you have data plan and like to turn on your wifi most of the time :)

you got to be careful using Juice Defender as it might reduce your battery life rather then improve it but its definitely worth a try... good app :)

[General Topics] Xenova:
These are especially more useful if most of the time if you're out there for 1 or 2 days and every percent of the battery count.

Personally I have 3 batteries. You are right, the way to use a phone is just use it and don't so particular about the number (especially in daily normal use) and be happy by getting all the smartness of the phone
[General Topics] chrcol:
Because to everyone its used in a different way, to you it may be a portable mobile internet multimedia device and phone 2nd.

To me however its a phone first and as a 2nd use it gives me internet access. I expect a mobile phone to last for many days between charges.

tasker

I don´t think tasker help a lot too, it´s just a suggestion because it turns off things when I don´t use like sync one time for a day only, turn brightness low after 11pm wifi on and off, but it consumes ram and cpu, so the tasker consume or save battery?

I was WONDERing

since I started using tasker to turn on airplane mode at night without it been disabled hourly to allow sms to come in, my battery drain has shot up.

2 charges in a row from an average of 5 days down to around 3 days, it shows not everything is what would expect, tasker is probably chewing cpu monitoring the time so it knows when to toggle airplane mode.

[General Topics] Kumarankav:
Wow really cool tweaks, thank you
[General Topics] RyanWyan:
I have a tip...

So, I know it's pretty much common sense, but nobody does it..

One good tip, is to turn your brightness all the way down and turn auto-brightness off, and also, keep GPS off when you're not using it... Be sure to keep Wifi and Bluetooth off when not in use too!

And if you're really low on battery, but you can't charge it and you need your phone, (this happens to me because I don't drive and I go see people often) you can go to Settings, Wireless & networks, Mobile networks, and un-select "Data enabled" be sure you turn it back on! (This is your 3G [and/or] 4G.)

Well, for me, here is something that works:

-Always keep your screen brightness at minimum. Smartphone screens recently have enough contrast.

-Use as little home screens as you can.

-Don't turn on 4g, 3g, gps, data packets unless necessary.

-Use as little widgets as possible. Prefer full apps over widgets.

-Turn off animations.

-Turn off haptic feedback.

-Turn off general interface sounds, like touch sounds, etc.

I don't see any great changes... but,

I'm posting my settings. To help and be helped :cool:.

My device is an .69 rom the clean 'n' tweaked with v2.8 Rage Kernel, xperia mini st15i

I don't want overclock only undervolt, so my clock settings are the default.

Images attached.

Edit: instability with AutoKiller and UV settings from the guide in this envrmt.

AutoKiller works awesome with the settings from the guide on stock.

Edit: CPU Control app show a message: the kernel don't have UV capablt. Rage Kernel do OV but not UV.

Trying to fix AutoKiller haha

Edit: Some AutoKiller configs causes conflicts with Rage Kernel, because the kernel is already tweaked, ima noob xPP. Removing AutoKiller... but the kernel only have a nice batt consumption.

My method is to keep a bricky extended battery in my backpack. My dinc2 with CM7 usually lasts through the day even with some considerable gaming. I've rarely had to pull out the brick. I even have it overclocked to 1.3ghz.

After upgrading to 2.3.6 from 2.3.3 battery life seems a large jump up, in 10 hours its used 4% battery and the awake periods on the battery graph are tiny so the phone seems to go back to sleep much quicker.
[General Topics] SolidMGSnake:
thx
[General Topics] Xenova:
Ya, you need a kernel that support undervolting. I believe each ROM has alot of kernels to be chosen from. You can ask around the thread.

This is how we undervolt (basically it's all try n error)

1. Only change the voltage of the frequency that you will use

For example:

ur max cpu freq is 10750, then no need to set the voltage for freq after that, leave them as it​

2. Reduce all voltage by 25mv, then use "TEMPORARY".

Try to use it for at least 1 day, don't just leave the phone there to sleep. Use it.​

3. If not sudden freeze or shut down, go lower by 25mv.

4. Until you find ur phone freeze. (for example: reduce all freq by 100mv)

5. Revert to the last setting that works (for example: all freq reduced by 75mv)

6. Now start to reduce ONE frequency at 1 time (for example: Freq: 384000, reduced by 100mv, the rest of the Freq remain as -75mv)

7. Use the phone for at least 1 day. If stable, continue to the next freq (example: Freq: 460800 reduced by 100mv). Continue this for the rest of the freq that you will use.

8. This process is to make sure you at identify the frequency that CANNOT go lower. So the one cannot go lower will maintain.

Try to caliberate your battery each time you flash ROM.

Cuz Rom will take the existing voltage (e.g. 3.7 @60%) as your new 100%.

Save batery

Hi everyone,

In my opinion and experience the best way to improve a better batery capacity is using a friendly batery kernel and a combination of diferent profiles in OC/OV app.

For example I'm using semaphore kernel and at the end of the day I still have 40% batery, and it's my professional phone.
