For me programs that automate data usage don't help my battery at all. Always causes wakelock issues since the programs service is always running. My battery seems fine for me though, I got autosync & background data running and I normally can get around 30 hours from the battery with an average screen on time of about 4 hours. 5 Hours screen on time if I'm web browsing rather than playing games. I always leave the phone running 3g/hspa+ just see what how it would fare. Could probably get another hour out of the phone if I used wifi instead

Guys,

I do think that Battery Calibration app is a useless method.

Maybe I am wrong but let's brainstorming here

I can remember a saving settings option on this app (if my memory is good), so if you give me your saved file, I can include it on the first post with pleasure :)

Your thread is interesting. I'am just a bit sceptic about this method but keep comments going :) so we will see !

At the beginning, I can't deny that I was a bit sceptic too, but after some rechearch and tests, it seems to be meaningfull.

The following can be saved as preferences.xml (I can't upload xml attachments) in the /sdcard/NoLED/backup folder, then you can go to Backup and Restore in NoLED and click "Restore" to import these settings.

Of course everyone prefers different settings, but I think I've struck a balance between battery savings and the usefulness of the notifications. People just need to poke around in the settings before decrying the app as inefficient (not that you've done so :) )

Best battery saving tip, turn off background sync and get in the habit of doing that manually.

The last thing you need is for a battery to sync in a weak signal area, because that's like a hot knife going through butter on the battery life...

[Galaxy S II General] AndroidGX:
Hey! :)

Just tried to modify your framework-res but it confirm what I was thinking before decompiling : I guess you are using JKay 12.1 mod, right? I had similar problem when trying to recompile my apk after modifying my values (anyway if you change them or not, it will be same problem).. and the problem is that framework file we are trying to decompile, has broken .9.png files. This happens when someone doesnt change the .9 png the proper way. People think you can just edit the .9.png like a normal file and you cant. While yes they work when flashed (sometimes) they break when decompiling it. The log file shows you the files that are broken.

So to sum up we should ask for JKay to check this (if not already asked) on his thread but I'am actually too lazy to do it :p

I gonna edit my first post on the way to avoid people giving me JKay 12.1 framework-res.apk :( hoping it will be fixed in futur releases. :cool:

I want to ask about sync,,, If i disable auto-sync, how much battery it will save ???

The main reason i sync facebook and gmail is to get email alerts,, if i disable auto sync, will i still get email notifications from gmail ???
[Galaxy S II General] AndroidGX:
A lot. Sync is the most draining thing on our smartphones. You will clearly see a big difference of you disable it. Just try it.

No, as you force disabling automatic data receiving for those apps, but you can always put interval refresh, works for Facebook (every 2 hours seems good ratio between refresh/battery saving), but not for Gmail app (sadly..), you can use "E-mail" app instead and set an interval aswell.
[Galaxy S II General] marvi0:
Used to be sceptical about juice defender, but for me it appears to work not sure whether it's just psychological thinking, but it appears to do the trick. Also being in uk, am on vodafone and only get about 750 mb data, so having my data cut of at intervals by juice defender means I save data as well. Otherwise if i had unlimited data, i wouldn't worry too much about juice defender. The evidence for and against it is well documented, give it a try you never know.

[Galaxy S II General] AndroidGX:
Thanks, glad you like it :)

My favorite modem thread is so far this one which give you some idea about battery life of each modems. I'am actually with XXKI4 modem and very pleased, but anyway, every devices are different, there is not 1 to eat them all, it's like roms, kernels, etc ;)

btw, you can use <2.3.4 modems into >2.3.5 without any problem since it's not versions related, it will be compatible :cool:
[Galaxy S II General] Perceval from Hyrule:
Thanks for your link GX, didn't know aout this thread - being on XXKI3 too long ;)

For instance, using several of the tips provided here, I get correct lifetime in Androidmeda 4.4.7 (http://xdaforums.com/showthread.php?t=1288850).

This lifetime can be extended because I'm using live wallpaper, wifi, autotask killer... But I've set SetCPU to wake clock 100-800 MHz onDemand and screen off 100-200 MHz conservative.

You can use your Galaxy S2 @ 800 Mhz, it's smooth (not as smooth as 1.2 GHz) and usable for almost anything you can do :)

You can even use 500 Mhz, but it's not smooth enough (for me ! Test and see if you like, most of time it will work perfect and you'll save even more battery).

ScrenOff profile @ 100 or 200 Mhz is fine most of time, but it's lagging a bit while getting incall (only first seconds : it will take few seconds for screen to turn on, that's the only boring thing).

Also note that weird battery "self-charging" ^^

About task killer, it's your choice : task killer drains battery, but kills apps you don't use anymore. Since these apps are/were stored in RAM, they continue to work (connect to network, cpu usage, ...) and because it's in RAM, it needs power to keep it in ;)

So.... task killer empties ram and save battery, BUT the process uses battery.

And running background apps drain battery because they're stored in RAM and because they're still running. It's up to you to choose how you can optimize your battery regarding which apps you use (ex. xScope browser should be automatically killed OR properly closed because it's using network and keeps lots of RAM... Meaning for you : big drain).
[Galaxy S II General] Mone181:
great thank you
[Galaxy S II General] sutheep:
Thank you!

Great Thread, extending battery life from 8 hours to almost 20 hours!
[Galaxy S II General] A|ex:
task killer is a battery drainer, yes it can kill tasks that have not closed but you can do that in standard Android OS anyway. Also majority of the popular apps will kill on exit.
[Galaxy S II General] r3dd09:
Most people never think of this, but it's true. the good thing is, that it doesn't drain the battery like other apps. A lazy killer is better than no killer.
[Galaxy S II General] Perceval from Hyrule:
Sadly, most of apps I run do not close after exiting. Sometimes, even by using the "regular method" to fully close app (press return until going back to Launcher).

It's very hard to know if task killers are so battery draining, I'm using Android Assistant and it's using about 0.20% CPU, where for instance SetCPU uses 0.09% CPU and stock launcher 2.60% CPU.
[Galaxy S II General] andreagragnato:
I've seen the best power saver is that one already included in the phone. Go setting-energy saver-setting-mark everything. It normally came on if battery level drop below 20%, but you can leave it on manully since when battery is 100%. It reduces cpu speed, rendering video and other hot stuff. I use every time energy saver on and I've obained 3 days of battery. You should add also data enable widjet to manually swith on and off data connection without any background process. Performance are a little slowed. You can see the difference mostly on launcher animations but application, web, navigator and other stuff works as the same way as without energy saver on.

Trust me, it works better than any other complicated app

Biggest drain I have found are apps that sync in the background.

I've made a habit of checking the settings of each app to disable sync and notifications. Worst offenders:

Facebook ( all off except messages)

Google reader ( manual and never use the widget)

Beautiful Widgets ( weather sync needs to be 8 hours for me at Max )

Hope this helps.

[Galaxy S II General] Perceval from Hyrule:
I remember we are able on some Chinese tablets to change power consumption of Wifi component. I'll check this out if I have some time, but it might be interesting to do so on SG2 :)

Also, if some extra-terrestrial people are using Galaxy S2 without any cellphone providing (no SIM, etc...

only

using Wifi/Bluetooth), you will gain hours by deleting/renaming phone.apk.

Don't do this if you use cellphone providing ! You'll lose phone (I don't know if you keep VoIP function), cellular data, etc etc.

Also, dunno if it's already stated by AndroidGX or somewhere else in the post, but it's interesting on some roms to use Smartassv2 profile (ie on CM7.1) and create SetCPU profile for screen off 100Mhz min - 200 MHz max (on underclocked kernels, like Siyahahahahah) :)
[Galaxy S II General] AndroidGX:
As far as I can remember, at that time is to undervolt wifi component, I saw this on "Phenomenal" kernel.

*edit* : can't see anymore this information on the original thread, so I guess it's been removed or my brain was burned or something :p

Be careful about Phone apk, should NOT be removed since it's critical one (cf. here at line "Phone.apk"), I don't recommand this at all.

I can remember using smartass (the first version) on my sold galaxy tab first gen (which I enjoyed pretty much btw :p) it really was a nice gov, which saved me a lot of battery, but governor's depends highly of each devices, here also we cannot say there is one governor to govern them all :D, as always it depends of each people, their needs, etc. I tested smartassv2 and was dissapointed by it surely because of Siyah's kernel. That's why I don't use it anymore, this kernel drains a lot of battery, generally speaking. At that time the best kernel I should recommand is NEAK 1.4x, with every options to save battery enabled since you will not lost any performance thought. Would be nice to see smartassv2 gov into NEAK one day :) (starved to test).
[Galaxy S II General] Perceval from Hyrule:
+1, it should not be removed (especially on Samsung roms, it is probably linked with TouchWiz). On my father's tablet (a Chinese MID 7" 799ca) you can remove phone.apk : causes no problem (!) and heavily enhance battery.

I suppose so you *might* remove it from any vanilla rom (no rom with overlay UI, it will make framework.jar crazy lol), but the main idea remains the same : phone functionnality (phone, data...) is one of the most draining stuff on our devices.

As AndroidGX said, if some newbie read this : do not remove phone.apk, ESPECIALLY if you don't know what you're doing. This is for testers/devs and suicide people. It will make you gain lots of baterry at the cost of misc FC and... woops I can't phone anymore with my phone :D
[Galaxy S II General] carr823:
sound great

thanks for your tips
[Galaxy S II General] AndroidGX:
Exactly :)

Your tip must works perfectly with devices who dosen't need to phone with, especially good for tablets without 3G. Unfortunately, for our SGSII : forget this :p

I think I will add asap on first post a list of apps that should be removed by default from Samsung rom's, as they drain much in background, I'am wondering why I did not this before :D

*edit* : tip now added on first page ! enjoy ;)

Ok..lets discuss the advantages of UV..will us??

http://xdaforums.com/newreply.php?do=newreply&p=22126846

Do you agree that UV will give more battery juice??
[Galaxy S II General] kangaroody:
how i tripled my standby duration

Here's something that works just perfectly for me and at least tripled my standby times:

First, I'm leaving network mode at GSM only most of the time and turn it on manually only when I really need it, i.e. use browser, youtube, maps or something...

Second I've installed GreenPower and made following settings (just the most important ones):

Manage Wifi: On

Manage Mobile Network: Off

Screen OFF wireless delay: 5 minutes

Wifi manual toggle: Disable Wifi Management until screen OFF

Wireless OFF duration: stay off

This automatically turns my wifi off 5 minutes after screen off and leaves it off until i turn it on manually -

YES manually, even if I'm within hotspot range. I am doing this, because in many many cases I don't need wifi when I use the phone, i.e. i dont need it for phonecalls, sms, whatsapp, reading or writing mails, reading ebooks and so on. For all the notification stuff i still have my gsm connection which consumes much less power than wifi and/or 3g and its quick and easy to turn one of them on only if I really need it.

Hope this helps.
[Galaxy S II General] ballonspotten:
Thank you for the tips

Thank You fot the battery saving tips! its realy works
[Galaxy S II General] AndroidGX:
I will be honest with you :)

After 2 years of pure android experience with tablets/phones, UV mean something yes, but it really depends on devices. On my old Galaxy Tab 7 inch, I can remember that with extreme UV values, battery was drastically better. But.. I will not say that it's as drastically as the Galaxy Tab does, at least on my own SGSII. When I talk about UVing on SGSII, I would say it's pure psychological. Finally, I don't really see real improvement about battery life while UVing on this device. I don't know if it's due to my galaxy SII, maybe it's different from all you guys ?

Anyway from what I've seen on my galaxy tab, I only can push everybody to UV their SGSII, even if I dont trust this.

Why I don't trust ? I don't want to read several technical links and pages about the subject that will proof that UVing will results battery gain, but I only trust my experience months with it and I talk from what I'm really thinking ;)

Hope you understood my opinion :cool:
[Galaxy S II General] A|ex:
Well i have creeped into 3 days with moderate use and a full 2 days of massive use after these settings. The biggest saver for me was under volting and using setcpu, the profiles provided gave ok power saving (mainly declock when screen off). I have added a lot more to mine and i manage to squeeze an extra few hours.

Turning the data off while i sleep was a massive saver

On every rom I have used, when I'm outside in a pitch black situation and I need my flashlight on my phone. When I leave it on for more than 60 seconds, the phone automatically restarts. I suppose because the LED gets too hot? This is on Torch bright widget or widgetsoid flashlight using method 2 for led. However I'm fairly sure that using heart rate monitor app in the market the phone can stay on with the flashlight for more than 60 seconds. I'm going to test this now. This is weird since my HTC HD2 could leave the led flashlight on for hours if I wanted. Well I never had it on for more than say 20 minutes but it worked and the phone never restarted. Any help would be great, thanks!

By the way this happens on all roms including with all kernels and all radios.
