Extreme measures for better battery life

Whyzor · Dec 9, 2011

I've taken similar measures and have been able to go 11 DAYS on a single charge at one time, now averaging about 6-7 days per charge.

The important thing is to get the idle battery use down (< 1%/hr idle), and let important notifications through (using SMS is more efficient than keeping a 3G connection active.

I bought a larger capacity battery as mentioned above. I now run an Anker 1900mAh battery in my SGS2. Using Battery Moniter Widget pro here are the differences:

Stock 1650mAh battery empty estimation on average usage after a week:

approx 7 hours 30 minutes from 100% till empty
(bear in mind this is including approx 6 hours of phone calls with 3g enabled, lots and lots of sms, approx 3 hours of music, all via bluetooth with some random gaming for about 30 minutes, always on minimum brightness settings unless it's really bright, in which case I go up to a maximum of 50% brightness.)

Anker 1900mAh batter empty estimation as above:

approx 10 hours 30 minutes from 100% till empty
(same usage as above, but adding about 4 more hours of talk time).

The battery is no bigger than the stock battery and lasts a lot longer...plus the battery was relatively inexpensive from amazon.

I would also like to let y'all know that the measured mAh for the stock battery using the above app was 1570mAh, where the Anker battery has measured as below in my signature. I use 8 widgets (4 Color Note widgets, 1 Beautiful widget superclock, 1 Poweramp, 1 Widgetsoid Switcher and 1 Battery Monitor Widget Pro) on 3 separate homescreens.

Better Batteries: New Technology Improves Both Energy Capacity and Charge Rate in Rechargeable Batteries

phoenix_rizzen · Dec 9, 2011

JuiceDefender, SetCPU, screen brightness, and screen timeout seem to have the biggest effect on saving battery.

My Xperia Pro with factory defaults wouldn't last an entire workday.

With the above apps installed/tweaked, I get over 50 hours of usage.

Usage hasn't changed (GMail, GReader, G+, Facebook, Opera Mobile, some gaming, lots of SMS, some phone calls), but JD+SCPU have done wonders.

No animated widgets, dark wallpaper, 3 homescreens, data/wireless off if screen off (wake every 2 hours to allow syncing).

Omg, +1, that is absolutely epic research and graphene can be made quite economically too.. but I doubt that will stop them costing the earth

Here is what i call " my Special Extreme measures "

please note : that u might not apply all of the following but doing the most of them will greatly increase ur battery life

1- standard measures

- use Auto backlight
- use 2 to 3 pages for home screen at most
- dont use widgets unless u need to
- disable AUTO sync
- disable ( wireless - Data ) and only enable them when needed

2- advanced Measures

- use 3rd party apps [cpu scaling apps like " setcpu " - juice Defender]( but i dont use them )
- if u use mails and apps that require regular updates from the internet make sure to set the update frequency to 2 hours or to the highest period u see it reasonable
- if u use power widget/switch widget "make sure to tick the options that allows to disable the 3G while wifi is active " and don't use 3G if u dont need it
- if u use a custom launcher .. make sure not to use too much transition effects and stick to the Default ones

3- Extreme Measures

[ most of the following Requires Root and professional useres ]

- Use a Custom Kernel known of saving battery ( like speedmod for the sgs2 )
- open the titanuim Backup and do the following
Menu button > Batch > Freez ALL APPS
and tick all the System programs and widgets that u do not use or rarely use them
i always freeze the following in the SGS2

http://img812.imageshack.us/img812/7626/sc20111210001702.png

Note : that the Red ones are the system apps .. only freez what you know
and only freeze what u really dont need or use including the unused user apps wich are the white ones
u can defrost them anytime u like
- at the end calibrate ur battery for maximum performance

One thing that I found that helps a fair amount too is a tool called "Autorun Manager". It tried to keep applications that start automatically from starting. If you get the pro version you get this feature called persistant mode which will stop it every time it tries to start. It's really useful with apps that run a lot on their own.

In addition to that, I've deleted app that I rarely use. Sometime they connect in the background even when I don't run them which I can see through my battery stats, so I delete them.

EDIT: also I have a 3500mAh battery for my Infuse. I get ~2days with standard use on Galnet MIUI

The most extreme I ever went was disabling anything wireless, min brightness, UC to 122MHz, pretty much just using it as an oversize watch. Got about 4 days from my dhd.

I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.

I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)

What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.

Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.

Change the Network Mode to GSM Auto (PRL)

whats the difference between 'autostart' and 'autorun manager'?

Neuron · Dec 10, 2011

i have my NS OCed to 1.36GHz, have 7 homescreens almost full 5 of which are widgets with news (tweeter, pulse etc) i use it to message a lot and have music playing for a good number of hours daily. wifi permanently on (in and out of house) sometimes cell data and BT as well. still it manages to get a full day, 7:30am-12:30am with around 20% left each night

Autostart runs programs/scripts when you boot up and autorun manager does the opposite. it block apps that try to start by themselves at boot

Actually.... Autostarts is the name of an application that also lets you remove apps from automatic startup on various system events...

so technically they both do the same thing?

deathsled · Dec 10, 2011

Are these really extreme measures?

I've been running 1 homescreen with no icons or widgets with all autosyncing disabled since I got my EVO well over a year ago. I considered all of that stuff pretty wasteful to start with. I was just trying to make the phone feel less cluttered. Turning off synchronizations is probably the biggest battery saver.

An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.

An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

Sent from my Wildfire S

Thank you. I assume everything I download is an app, and the widget is that newsreel that came with it that probably sucks battery because it's constantly updating online.

Buy the biggest battery I can find on eBay....

Use the fsck out of my phone all day and have plenty of battery left.

Problem solved.

They make larger batteries than what comes with a phone?

hi tl;dr but your title is self-explanatory. Download Tasker :} You're welcome ^.^

On my HD2, I have Nexus HD2, version 2.9, with tytung r10. I have also installed Android Assistant, Battery Calibration and BetterBatteryStats. My phone ''it's alive'' even after 4 days in standby.

Moscow Desire · Dec 10, 2011

3 months. Leave phone turned off

Seriously, who said 11 days???? (know what my reply to that is

)

Same with 7 days for that matter, although if you remove the SIM functions, it's theoretically possible. Or just turn everything off so it looks at you with a black single color screen.

4 days, max. With cpu profiles. simple usage. Sms, occasional call. CM7.1.

leonardoaraujo · Dec 10, 2011

for me is also the type of user, using battery drains very quickly, if it can not last long ..

the only thing that made all the difference for me was setting underclock when in standby ..
Let me give you my example:

I have a Motorola Atrix (CM7)

screen on = 1GHz

on 3G
wifi off (turn on only when I use, but can be used to "political inactivity")
Bluethooth off (I do not use)
Sync off (turn on from time to time and do the sync, do not let on at all times, also drains the battery)

Screen off = 912Mhz

Off 3G, only 2G
Sync off
wifi off

I also use droidwall and blocking access to the Internet from almost all my apps, with the exception that I do not want blocked. (blacklist)

---because manufacturers do not make larger batteries???
---because with so much technology in the devices has not had any moron that made the backs of smartphones solar cells to help recharge the batteries???
"In the case of my country that would be quite functional"

-----I sometimes feel I have a maverick v8 (ATRIX), but my gas tank (battery), is nothing but a bottle of coke .-----------
