What do you recommend for extended battery?

What do you recommend for extended battery life,preferably something that doesnt include me flashing another rom. currently on cyanogen.

well...
I use Juice Defender to control data connections, etc.
Also, I use nemesis2all's OTB kernel http://forum.xda-developers.com/showthread.php?t=1119169
and use the "voltage control" app to undervolt my phone.
That's a pretty good start right there.

I know you want to extend your current battery life, but I use the above. Works pretty good. Ya it makes the phone bigger, but really its not a big deal.

I've been getting amazing battery life while overclocked and undervolted using nemesis2all's OTB with CM7. And you can also change the screen rendering effects in CyanogenMod settings. I used to use juicedefender, but now I find it easier to just manually toggle data in the notification bar.

[Q] Question about Kernels

Hi, my Triumph should be arriving in the mail in just a few days and i was wondering which is the best kernel or ROM and Kernel combination that is best for battery life? I've heard that battery life on the Triumph is not so good. Maybe it's false but i would still like to know.

I would go with CM7

That's what i was planning on. Does your Triumph give you battery problems?

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.

It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.

CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.

[Q] Which kernel is best for Stock ICS?

Hi, first to defend myself, I did search and found that everybody says good things for every kernel. So every kernel is best for Stock ICS?
I got confused. Yes I'am total noob and recently learned how to root and flash custom rom's.
I just want to hear your opinion for best kernel running on Stock ICS.
I need kernel that is good for the battery but also snappy for the system. I don't play games and I use my phone for calls, reading news, working on excel files, google maps, mail and taking pictures.
My phone is Nexus S GT-I9020T on Wind network.

Thank you. Is this kernel stable?

Im just trying to set it up as we speak, will let you know how stable it appears once I figure it out
Stuck on trying to flash an unsecure boot image at the moment.

*shrugs* The stock kernel?
Unless you want the functions third party kernels bring to the table, I don't see a good enough reason to swap the stock kernel for another.

That's what I was thinking. With Glados kernel I had problems with restarting after the screen turns of, also with Matr1x kernel. Also I read that there are restarting issues with IMO ezekeel kernels. Yes I know that probably the most stable it's the stock kernel, but there is problem with battery, I had more juice with GB and CMD 7. That's why Google paused ICS update on Nexus. But probably I will stick with Stock Kernel because for me it's better to have less battery for now instead random restarts. I hate when my phone it's not in perfect state.

Just managed to get ezekeels CFS on there and I get the reboot bug after going to standby.
Looking for updates but the thread is huge. Yet to try BFS.

You can try and turn off deep idle for your reboots.
Solves the problem 99% of the time (totally made up stat that could actually be true)

But actualy that function (deep idle) it's the most impotant thing in the kernel. It gives more battery time. Other thing are just fancy. More battery and no hickups, I dont need overclocking because I dont play games.

Deep idle gives more battery time under certain conditions (screen off but not completely idle, playing music for instance). It won't really give you more battery time if your phone is actually idle with the screen off.

But according to this http://forum.xda-developers.com/showthread.php?t=1297535 I understood differently. Maybe you are right, I'am still noob to all of this.

The first post that you linked actually just confirms what I said.
Ezekeel said:
Since this is just theory and Morfic noted that his experience seems to indicate otherwise and that limiting the CPU frequency does actually decrease the battery drain, I put this theory to the test and logged the battery charge over 10h of FLAC playback in Airplane mode with the screen switched off.

1) Playing FLAC (not idle)
2) Screen off
Pre-requisites are met.

So as I understood the battery consumption is reduced only if you listen music, because you can't do anything else when the screen is off. And the deep idle is working only in standby mode (screen off).

Deep idle only shows savings if there is tasks running while the screen is off VS the same situation without deep idle.
So for someone doing commuting (like simms22 for example) and listening to music for around an hour, they'll lose less battery with deep idle than without.
You won't actually save battery if your phone is actually idle with deep idle enabled.
It's not some kind of magical function that makes your phone use less battery doing tasks with the screen on, deep idle disables certain components of the phone while executing tasks with the screen off, instead of having it "at full speed" as if the screen was on.

Now I understood. Thank you very much.

No problem. I think Deep Idle is probably the mod by Ezekeel surrounded by the most misconceptions.
Most new users want it absolutely but don't seem to know why.

On His Glados kernel I noticed that Android OS was using 20%-21% of the battery and on the stock kernel 30%-31%.
Android System was using around 14% and on the stock around 19%.

Ok, have you decided to give the Glados 2.2 another go? I believe I have finally tweaked it so that it is stable for me.
Before I was getting restarts within 30 seconds of the screen turning off. I have cornered this (on my phone at least) to a problem with NSTools auto-setting the lower frequency to 100mhz. Changing it back to 200mhz and I have yet to see the system restart itself. Im not overclocked, because I dont see the point as everything is fairly snappy with this new kernel. I dont really play games on it so Im not fussed.

I did used NSTools and the frequency was set to 200mhz and I had system restarting on screen off. Using stock ICS with Glados 2.2
Also I had green annoying flickr on locking and unlocking the screen.

Best rom for battery life

Hello guys,
as for me the most annoying part of a smartphone is running out of battery when there is no chance to recharge, I want to collect your experieces with different roms concerning battery life.
WHich rom gave you the longest battery?
Cheers

There are many factors not only the ROM.
It's the kernel you flashed, it's the settings you have chosen... and at least it's your daily behavior with your phone....
Usually you have a better battery life with custom kernels...

as it was answered
custom kernel with feature as ability to set minimum CPU frequency and probablly voltage control
and U'll have to try some of them in order to find out the wright one

Longest battery life i get with stock rom so far (around 20h with moderate usage)
for custom roms:
Best battery life gave me PAC-Man rom with bubbav4 kernel - which was almost like stock.
ViperOneS had the worst battery life for me.
just try some roms and kernels, it also depends on how you use your phone of course.

in my experience, 4.2.2 roms have the lowest battery life ~3.5 hours screen on + wifi on (active Web surfing) with auto brightness.
Viper rom 2.1 ~4 hours
aosp 4.1.2 (cm10) and viper 1.2.1 ~4.5
very rough numbers obviously so no one roast me. remember I'm talking about total screen on time as reported by the battery app.
The newer jb 4.2 roms are very popular and have a lot of great features, but if battery is your thing, try out some of the older android and sense roms.

For me it was pretty much a tie between Liquid Smooth with Bubba Kernel(OC to 1890 for heavy periods, 1134 for light usage, and complete collapse of the CPU when the screen is off) And Viper One S with the Stock Kernel. Like everyone said though you'll experience wildly different numbers depending on what settings you use and how much

Viper has always had phenomenal battery life.

Tips for Best Battery

So guys, its a fact we have a small battery for our phone but I was wondering, how do you get the best battery life?
Just post anything! What ROM your using, what kernel, your kernel settings or maybe a tweak you found.
I want this to become a help center for people who suffer from bad battery
EDIT: Also, have you guys expierenced a difference with unfervolting?

Try Greenify in the Play Store. It seems to help for me.

I use a Tasker profile that will disable mobile data when my screen is off and when it's not being used. Don't know if it helps or not I don't worry about battery because I have a a portable battery pack charger thing

I wholeheartedly believe in Greenify! I have it on my tablet and phone. I've seen a jump in battery life by about 30% since installing it. Not sure if you will have the same type of luck or not.

There's many factors that can be affecting your battery. More importantly it depends on the type of rom you are using, assuming it's sense based... Try using elementalx 6.6 kernel, it'll help your battery; tweaked with the right settings. Power saver also seems to help a bit.

This probably isn't what you had in mind but my best tip is to keep my old iPhone with me and use it for media consumption. That way my android always has a full battery for actual getting work done.

Why not just Greenify maps as suggested by others. Did wonders for my battery life, used to go to 15% in the evening, now regularly above 60%. I also use autostarts to kill some other processes that are launched by default

I'm using the stock Android 4.1.1 ROM unrooted. With my normal usage, I can get through two full days. I make sure to toggle off WiFi and mobile data when not in use, as well as toggle on the "battery saver" built into Sense. I also turn off sync for everything (Facebook, Twitter, etc) except for two Gmail accounts which only check for email. It's about on par with my old Nexus One that I moved from. Keep in mind, however, that I just got the phone and these might change, but this is what I've noticed thus far.

A combination of 2xBattery (toggles data connections when screen off) Tasker (toggle data in different times/locations) and Greenify.

When it comes to battery life, the basics really are the most important.
here's a couple:
1. Don't use auto brightness. It tends to keep the display super bright even when it's not needed. The display may very well be the component that draws the most power in the entire phone! Look for widgets that let you select manually (I use "Brightness widget - backlight" from Google Play and even manually, I set the brightest it can go to 79%) or apps that still let you have auto brightness but more controlled (Try "Yet another auto brightness" from Play Store).
2. Use a setup as stock as possible. I know some people are going to disagree with me , but having your phone as close to stock as possible will have the best proven battery life. I think some of the developers here do amazing work on custom roms and kernels, but when people report good battery life you should keep in mind that are so many factors involved that it's hard to replicate it if you want to. Carriers test their phones extensively to ensure good battery life, and while I am NOT saying custom roms and kernels is a bad idea, I AM saying that I believe a stock experience is a more proven option.
3. It also has been proven that undervolting does NOT help with battery life because not only the difference in millivolts is negligible, it may cause instability and finally a reboot, which just happens to be the biggest software-related power drainer.
Hope this helps

im running clearrom 6.5 but i havnt been able to get greenify to work really. when i install it, it only shows a couple apps that i dont really use to begin with. correct me if i am mistaken, but greenify will hibernate/shut off running apps and the apps that the greenify app shows are apps that are currently running?

Correct. If the app you want to hibernate isnt running you would have to run it to add it to the hibernate list.

I don't know if I agree 100% on that one. Undervolting can reduce the amount of heat discharge caused by too much voltage being provided. A hot battery affects battery life both in the short term, and the long term.
Yes, not all phones can handle undervolting (because they're already receiving a good amount of voltage out of the box), and will glitch and reboot, which drains battery.
But, for phones like mine (which I can generally UV by about -75mv without adverse effects), the reduction in heat can only be a good thing for my battery life.
Sent from my Evita using XDA Premium

Heat itself should not cause your battery to drain quicker. Heat is moreso an effect from the cause of something causing the battery to drain rather than heat causing the battery to drain faster. Heat can damage the battery which would cause it to drain faster... so what I mean to say is heat will often accompany the battery draining quickly but not be the cause of it. Hopefully this post makes sense.
Sent from my HTC One X using xda app-developers app

Yeah it's the damage caused by heat that I was talking about. I've heard a hot battery will discharge quicker though. But heat is also a side-effect of the battery providing the CPU with too much voltage, that extra voltage being provided has nowhere to go so that energy ends being dispersed in the form of heat. Which in turn damages the battery.

That is mostly incorrect. The voltage options we can tweak are not enough to make such a big difference, so you can and will still experience heat even with an undervolted cpu, provided the load is the same. And that's my point, that the difference in undervolting in millivolts is negligible yet one reboot can wipe out an entire day's worth of battery life "savings" from an undervolted CPU.

Ok well all I can say is UV'ing definitely decreases heat for me, particularly when playing games (which is when it heats up the most), and I can safely operate without reboots. Before you say it's a placebo effect, I check my temp regularly to verify it.
