speaking of which... is there a app or tool out there that let you selectively turn off the cell radio only? the airplane mode kills all my radios including wifi, then i have to turn it back on... my use pattern is wifi always on, but i only need cell when i dont have wifi

Is there a app that can manage screen brightness?

I mean automatically during the day increase brightness and reduce it during the night

[Optimus One, P500, V General] viv_jen:
I dnt use chainfire

So any other option?
[Optimus One, P500, V General] Marcovecchio:
Great guide! I would just add two points:

- Use 2G only: 3G networks uses a lot more power than plain old 2G. Unless you need network bandwidth, keep 3G off. For voice, there´s no difference in quality, so 2G is fine. I can easily double my battery life just doing this. For those using CM, it´s easy to add a 2G/3G toggle in the power notifications bar.

- Turn radio off in bad signal places: if you go into a building (or anywhere else) with weak or absent signal, simply turn off your radio, if possible. The phone will try to to compensate bad signal situations by boosting it´s own signal, using more power. Or worse: if it looses signal completely, it will keep trying to attach to a network, but will keep failing on this, wasting even more power.
[Optimus One, P500, V General] Whyzor:
Thanks for the suggestions. I've noticed that (at least on CDMA networks), that 1x data speed uses lower power, but it takes longer to transmit a certain amount of data, so it ends up using more power to get the same megabyte transmitted. I've also read that it's the same with 2G vs 3G data. 3G just transmits it faster, then goes into low-power idle quicker.
[Optimus One, P500, V General] nocterum:
using 2G(GPRS/EDGE) saves battery when you use it for like, transferring small packets of data and syncing things like news feed. For browsing and market obviously 3G is better choice but if you are doing a small google search EDGE is better as GPRS(if your location does not have EDGE) is too slow, and only fit for syncing and loading a dictionary app or XDA mobile app.
[Optimus One, P500, V General] matikemin:
Awesome. Pretty straight-forward. I almost forgot that i can set clocks in my phone :-)
[Optimus One, P500, V General] Vyom:
This is confusing.

I read somewhere that Overclocking actually increases battery life, since a task will perform faster due to higher rate of cycles.

But the OP states otherwise! :(
[Optimus One, P500, V General] Bec de Xorbin:
OP is right. But you can compesate battery usage by undervolting. AFAIK franco uses lower voltage in his kernel.

EDIT: I was wrong, he has overclocked FSB/BUS, so no undervolting. Guess it's not possible to undervolt our phone.
[Optimus One, P500, V General] lgp500user:
Thanks for the tips:) I will try to slightly increase the life of my phone)
[Optimus One, P500, V General] Vyom:
So does that mean, underclock uses less battery, or overclock?
[Optimus One, P500, V General] ninham:
I really don't understand why my phone's battery usually won't last longer than 12h. I've been using CM7.1 (mik's 6.5.8) for a month now.

I try and follow most of the tips listed. I leave 3G on because I use whatsapp quite often (turning it off overnight), but I wouldn't believe it drains that much battery. I've tried uninstalling other apps that run in background (twitter, facebook) and freezing some others that startup randomly (maps, dropbox). Background data, auto sync, GPS, bluetooth and etc are always disabled. I hardly ever play games. Also changed network to 2G only. Nothing seems to improve battery life.

In BetterBatteryStats, it says the phone was awake for 3h, even though the screen was on for only half an hour... There's also a significant wakelock (around 3h too) called GpsLocationProvider, even though I always keep GPS off. I attached some screenshots hoping someone can figure it out.

What should I do? I really want to be able to go through a full day at least without having to charge the phone.
[Optimus One, P500, V General] Agent3:
Thanks for the tip but I do heavy texting and calling. I sometimes use the wifi and every now and then the GPS and camera. I don't play games and the battery will last me for 2 days at most.
[Optimus One, P500, V General] santachaos:
After using GPS turn off it and reboot your phone to clear the wakelock
[Optimus One, P500, V General] Whyzor:
There is a theory that faster clock speed "races to idle" quicker, but it has limits when the rest of the system is slow like the memory reads/writes. Too slow of a clock takes too long to finish any task and ends up using more power. I would just recommend regular default clock speeds since without undervolting, the cpu freq is only a small factor compared to other parts like 3G radio, screen backlight, and vibration motors, which draw a lot more current.

The Optimus V had some gps wakelock bugs that have been resolved in recent CM7 ROMs. A lot of phones probably have unintentional wakelocks, only in ICS have Google started to try to make it easier to detect them.
[Optimus One, P500, V General] reven20:
thanks for the tips...I will try out
[Optimus One, P500, V General] preeth:
Thanks

Useful info. If my battery can last for 3 days without charging it even once, I'd be a happy camper.

[Galaxy S II Q&A, Help & Troubleshooting] mystic01:
My question is, how does a USB Jig work?

Why does this small cut-off/altered piece of a USB cable do what it does?
[Galaxy S II Q&A, Help & Troubleshooting] veyka:
It's a micro usb head with a 301k resistor between some of the pins which makes the bootloader reset the counter, theres loads of threads about this.
[Galaxy S II Q&A, Help & Troubleshooting] mystic01:
This isn't a thread asking about what the hardware is, the question is, why does it work? What's so special about this 301k resistor that makes the unit go into download mode and reset the counter?
[Galaxy S II Q&A, Help & Troubleshooting] ccrows:
NOOB question. Does anyone know if the USB jig for the original SGS works for the SGSII?...
[Galaxy S II Q&A, Help & Troubleshooting] kakarotto87:
yep bro, it works.

if i helped, use the thanks buttom :D
[Galaxy S II Q&A, Help & Troubleshooting] Sideromelane:
I'm in the preocess of making my own jig, just picked up the resistors today (300k and 1k since maplin suck and dont carry a clean 301k)

My guess is that the jig works by sending a low voltage signal down a normally disused USB line.

USB 2.0 heads have a fifth 'unused' pin, specificly for manufacturers of devices to add in thier own proprietary signal line. By shorting the ground and a signal pin, via the resistor, you probably trigger a reset signal to the phones 'bios' rom.

And why 301k ohm? Probably, originally, to make it harder for non-samsung personel to 'guess' the correct trigger voltage. It could have easily been 235kOhm or 20M Ohm or anything.

This is conjecture honestly, but it makes sense to me.
[Galaxy S II Q&A, Help & Troubleshooting] nicksnoobie:
It works. Had a jig for my Captivate and now using it for SGSII
[Galaxy S II Q&A, Help & Troubleshooting] 3waygeek:
IIRC, the resistance is across the two USB data pins, at least for some functions, e.g. determining if you're plugged into an AC charger. There are several significant resistance values in the addition to the 301k ohm you cite. Other values will put the SGS2 into dock mode, or put the device into MHL mode, where the micro USB connector is repurposed to send HD video & audio to a display, either a MHL-compliant device or a HDMI device after going through the MHL-to-HDMI adapter.

[AT&T Samsung Galaxy S II SGH-I777] brent8577:
i read that people had notification bar burn in on these AMOLED screens after a few months of use. i know that within the first year, i can exchange it for another one if this happens, but i'd like to avoid that. do these screens really do that or is it not true? i've set up Gentle Alarm to work with the Samsung Galaxy S dock, which makes the screen stay on if i don't exit. the idea of leaving a clock on for 8-10 hours has me worried.
[AT&T Samsung Galaxy S II SGH-I777] winnotcho:
If you go to the at&t store and look at the infuse models that have been out for a while.. You can see definite burn in the screen.. It was pretty bad when I was messing around when I bought my gs2... I'm hoping it's from the screen dabbers that they have on the phones.. I think you should be fine..
[AT&T Samsung Galaxy S II SGH-I777] link12245:
Yeah, those phones run 24x7 and most of the time they get stuck on the 'Unplug your charger to save battery' for 8-9 hrs at a time, and thats where we see a lot of screen burn in. You won't see this from day to day usage, but if you leave it on all night every night, it may burn in.
[AT&T Samsung Galaxy S II SGH-I777] BarryH_GEG:
One of the downsides of OLED is burn-in. There's no way around it. Why don't you order the official Samsung dock? The phone has built in docking s/w that recognizes it and the time moves around the screen when idle so there's no risk of burn in.
[AT&T Samsung Galaxy S II SGH-I777] brent8577:
that's the dock i have, but the box doesn't have the II on it. the phone fits, the blue light comes on, and the Samsung Desk Home opens up with it. i had just set it to Gentle Alarm since i'd grabbed that from Amazon. i'll check the Desk Home style and use it instead if it moves like that. thanks!

[G2 and Desire Z Q&A, Help & Troubleshooting] ibrahima:
guys how can i put a bunch of applications in a zip folder a flash it by recovery.Ive tried putting 3 apps in a zip folder and flshing it via recovery but it says failed..
[G2 and Desire Z Q&A, Help & Troubleshooting] gee one:
I tried that a while ago on the g1 with mixed results.

You have to put them in the data/app/ folder the same way they appear on your phone. If you are feeling ambitious, you can also grab the corresponding folder in data/data. You'll have to look for the java package name, not the app name. Lastly, you have to adjust the updater-script in META-INF/com/google/android/ to mount and flash the data folder, not system and then clean out the extra cruft.

You might have to resign the zip or just toggle sig checks.

Other options include using recovery to restore the data partition, but this will be everything, not just your 3 favorite apps. Alternatively, you could write a script that runs from your PC while your phone is in recovery and use the "adb install" command. I think there are also apps that do that for you, such as Titanium backup.
[G2 and Desire Z Q&A, Help & Troubleshooting] ibrahima:
Gee one thanks for the reply but can you plz reexplain "If you are feeling ambitious, you can also grab the corresponding folder in data/data. You'll have to look for the java package name, not the app name. Lastly, you have to adjust the updater-script in META-INF/com/google/android/ to mount and flash the data folder, not system and then clean out the extra cruft.

You might have to resign the zip or just toggle sig checks."
[G2 and Desire Z Q&A, Help & Troubleshooting] gee one:
Your phone stores the app in data/app/some.java.name.here so if you use flash those files, your apps will be installed. The app itself stores settings, history, etc in data/data/some.java.name.here If you flash the corresponding folder in data/data, you'll also get all your settings and won't have to bother setting it all up from scratch.

If you use adb or a file explorer to poke around in your data/data and data/app folders, you'll see what I mean.

In order to get the zip to flash, you have to include "instructions" that tell the recovery what to do with the zip. Unzip one of the flashable roms and look in the META-INF/com/google/android folder. There should be two files there. You want to edit the updater-script so that it flashes your data. Most likely, it is set up to flash a custom rom to your system folder. You'll have to do some editing and some trial and error to figure it out, but if you are just flashing the data partition, most of the commands in updater-script will be superfluous.

Lastly, and this the part that everyone hates (second only to adding adb to your path), you either have to sign the zip with jarsigner, signapk, or something similar, or turn off signature checking in your recovery. Signing the zip is essentially adding a digital signature so that your phone knows that the zip is intact. Clockworkmod recovery will let you toggle the signature checks in one of the options- poke around and get familiar with your recovery. It's probably in there somewhere.

I think Titanium backup will let you freeze/unfreeze apps- you might want to consider it.

[Desire Q&A, Help & Troubleshooting] danarama:

Actually after using the cwm application included with the rom i noticed that it installs the zip file as it would with cwm but all i see is a pixilated screen as before ..

everytime i use the cwm app or i use the 3 button combo to access it , it gives me a horrible pixilated screen or just restarts the phone ???

additionally every time i download an application from the market it disappears when the phone restarts for some reason...Overall after messing around with this rom it definitely has a lot of potential.
