Bad Battery Life

I'm getting bad battery using my phone. Can you guys recommend SetCPU profiles or settings, or do I need a new battery? Thanks!

In case you've set a min/max something like 19 (min) to 768 (max), try setting the min quite a bit higher, like in the 200-400 range. See if that helps. Also, don't go crazy setting a whole bunch of profiles. In fact, for troubleshooting, don't use any so you can narrow things down.

245 245 works really well and doesn't make the phone take forever waking up

Not specific to this topic, but I suspect you really see much difference between 806 and 604...
For your screen-off profile, change the min to something like 245. Just try it for a day or two and see what happens.

I too have poor battery life. We're talking down a percent every 2 minutes. I'm running the Droid does rom. I'm gonna try your settings and see how that works.

My battery drains fast too. I stopped using setcpu. When I'm not using the internet I turn it off. Now my battery last a lot longer.

im at 710/844 2**/4** with half decent battery life. but i do stil walk around with a charger
getting linpacks of 5.783 @ 844mhz!

Well a lot of you have seen my posts on this subject but the op asked so...
I have no setcpu installed, no autokiller. The Froyo ROMs are default set to 710mhz and I enable JIT as it helps battery life. You also NEED to calibrate correctly to see best battery life.
CGriffiths86 summed up my long winded version of battery calibration like this...
1. Fully charge the phone
2. Shutdown, boot into recovery, and Wipe battery stats
3. Reboot from recovery and use the phone as normal until it completely dies
4. Fully recharge the phone
With battery cal, no setcpu, and no autokiller, I get 27-30hrs on a full charge with solid use all day including bt music playback, navigation, calls, texting, and minimal web access.
The other settings I use are.
VMheap 24
Screen at 35% brightness

N2...
What about the other 2 settings with JIT? Do you have them checked or unchecked? Comcache? and Dithering?

I dont use compcache (although I have read that it works well with FROYO based ROMS), and I dont enable surface dithering (doesnt add that much crispness to the display to me and takes away from processing power). I dont believe either of these settings will have much impact on battery life though so try them out and if things are still as snappy as you want then MPTY.

oh yeah try turning off auto sync it helps me a bit

Using CELB 2.8, I get about 24-30 hours of battery life with a fair amount of usage.
http://www.techradar.com/news/phone...android-battery-life-should-last-a-day-690439 when Page made this comment, I was at the time convinced that my phone itself was to blame and quite incredulous with regard to his statement. Turned out...he's right, at least in my case. I'd say stop looking at OS settings and focus on the apps you have installed.
I was having absolutely terrible battery life, even with this rom (though at version 2.5 or so), and couldn't figure it out for the longest time. The culprit turned out to be NewsRob, an RSS reader that syncs with Google Reader. I had it initially set up to sync every 4 hours or so, but the default is 1. Somehow, thanks to Apps2SD, when I flashed a new ROM, the sync settings reverted back to the defaults. I finally figured this out and changed my settings to manual sync and battery life has been epic ever since.
Another app that I think was causing some drain was Locale, as it's constantly polling your phone for data about its condition. I stopped using it altogether and am just out the 6 bucks, I guess.
And another thing that helped was completely removing AutoKiller from my phone.

This is gotta help a lot, thanks! And thanks to the other guys for quick replies!

With a full battery in the morning, o usually have about 20% left about now which is 10:53pm EST. I charged all night last night, wiped battery stats this morning as soon as I took it off the charger, and I have 52% right now! And I have used it more than I usually do. I don't know why that seems to have worked but I hope it does the same tomorrow.
Oh yeah, Setcpu set to 710 max, 245 min, screen set to manual brightness at 45%

Go on ebay and search for HTC Eris batteries. For $15-20 you can buy 2 extra batteries with an EXTERNAL charger. I run my batteries to 15% or less, pop it out, put in a fresh (cool) battery, and put the dead one on the charger. No more carrying a charger everywhere I go or using a landline because my cell is about to die. Then your settings don't really matter. Even if you can use 3 batteries in a day, you'll have a fresh one (or 2) charged by the time you burn up the 3rd one.

Wow, the vibrant's battery.

I just switched from the G2, and I don't seem to be getting as good of a battery life. I just went down from 50 percent to 4 percent in 3 hours. Is this normal?
I don't think my phone is sleeping when the screen off. I'm kind of new to android, so excuse me asking, but how do you check if you phone is not sleeping and draining battery while idle? Is there an application or something to check?
One more thing, I just got the new update yesterday. I heard that it's not good to use a task killer, but I'm now using the built in task manager to close apps before I lock my phone seems to be helping with battery life. What are you opinions on this?

Check the battery thread, life seems to vary along among the Vibrants. A lot are reporting 11-15 hours of use before needing a charge.
I read that it's good to put Wifi on never sleep (if you're on Wifi) and use a black wallpaper

Interesting, how do I go about changing the wifi to never sleep? I can't find it in the settings!

Drm running. Go2 apps running- Apps & stop it
Vibrant + xda app

If you change WiFi to never sleep, it eats battery like crazy (at least for me, I'm bought with no data, and could barely last a day from when I woke up to going to sleep). With WiFi art to never sleep when charging, I only drain around 40% in an awake day (from when wake up to going to sleep).
Also, when I set WiFi to never sleep, my cell standby usage skyrockets.

Extend battery life
Couple of things I have noticed with this phone
1. Get an app Task manager or similar type apps. There are a bunch of them in the store and here. This will allow you at one click to see what is on in programs and better manage that.
2. Go to the Development section here and read the Bionix 1.9 Thread. It explains how to recondition the battery. Even if your battery is new it is good information understanding how the phone views the battery.
3. If I am out of range or do not need, I stop the wifi and bluetooth. In the menu you can set the settings alot of ways, so you just have to experiment on this. (In home screen, hit lower left button and go to settings)
4. I use my email and phone ALL day (min 10hrs) and typically, I get 15-17 hr of use before it hits 10%
5. Finally, once you are comfortable with the phone, you can load a custom ROM from the Development section. The developers here are very through and Do squeeze the most out of the phone.
Good luck and you will love the phone as I do.

1 - terrible advice - esp with JI6 having one built in (long press home).
2 - This is also in the General sticky
5 - try bionix 1.9.0 (or 1 if you want alt lock screens) and try JACs oc/uv - great battery life so far.

On average use I get close to 24 hours out of a charge using mostly WiFi and enabling no-sleep option, running Bionix 1.9.1 with stock kernel with JI6 modem. I'm also running LauncherPro Plus with facebook widget set to auto-refresh every 5 minutes, the most frequent setting for Google sync, and NoLED notification. I think that is very reasonable.
p.s. I do not use task manager since the operating system is supposed to manage the apps on its own.

I use an app from the market called Y5 (free) to automatically shut down wifi if I'm in an area without it and back on if I'm in an area with it.
Works well for me.

My vibrant is less 23% after being off the charger for 4 hrs. One of those hours was me driving without using it.
Something is wrong. Dunno if it's the update, but something is lilling it FAST - wifi ang gps off the entire time...

I use the living hell out of my Vibrant, and usually it lasts for about 4-5 hours. This being during playing games with brightness maxed, or streaming music over 3G and/or Wi-fi.
If I have a day where I am not doing the above, and just using my phone for emial and the facebook and gmail synching, I easily get over 10 hours before I hit 20%.
All in all I am quite happy with it's battery life. I have just learned to leave my phone on the charger till full charge after streaming music drains it to <20%.
I really should put MP3's on it and test how much that drains the battery compared to streaming.
Either way, I get better performance on battery and memory management then my old (work supplied) BB Bold.

My G2 definitely has more battery life than my Vibrant. That said, once you apply the above mentioned tweaks and especially with JAC's OC/UV kernel, and setcpu set at 200-1000 at conservative, the Vibrant battery life improves quite a bit. Still, its not as good as my G2. But not that bad either..

Keep in mind that the G2 doesn't have to power a billboard sized SAMOLED screen either.
Other than that flash on of Sombionix's ROMs with either of the new kernels and then recondition.
I get pretty good battery life because I don't have 3G in my area so I keep it forced to edge and I don't use bluetooth ever and wifi stays off unless i need it.

Ditto!
Fully charged on the way to work. On the charger less than 4 hours later with moderate use. No better after update. Was using a task killer with minimal improvement. Love the Vibrant but despise it's battery life.

Something is wrong. I just went 26 hours down to 19% before charging

People, recondition the battery. It's easy.
Charge it to 100%, keep it plugged in and reboot to recovery, clear the battery stats, drain it all the way, then charge it back to 100% again.
You can start in the morning before work/school and finish at the end of the day. I've never had an issue with battery life on this phone. I can play 6 continuous hours of video/games on this thing and still have battery left.

Battery Life Horrible

this just started starting recently.
battery drops 5% under 1 min without even use of the phone. on standby.

ran battery dry than charged it back to 100% and did battery calibration. still horrible!!

Check battery usage under settings see what's using it up. also check your CPU settings. Although I've had that kind of battery drain. Sense just hands down has terrible battery life. Go AOSP.

Whats a rogue app? And how do you get over 24 hours on battery life?

yeah Sense does drain the battery, but the UI is just awesome IMO. I get roughly 19hrs on a full charge with moderate usage(deleted bloatware, setcpu profiles) whereas on AOSP I would get 25+hrs on a full charge with same usage. really, the 'display' is the battery killer on sense. try to lower your backlight brightness, no window animations, and lower the screen timeout to see if that helps you

An app written badly enough to cause CPU to hang in 100% (sometimes it hangs the system, and then the system shows 100% CPU constant usage).
Happened sometimes to me on Nexus. Sometimes can also be caused by restoring system data from backup, if the system data isn't fully compatible.
When I almost don't use the phone - I can probably get past 40 hours of uptime before needing recharge, since the idle drain is somewhere between 1%-2% an hour for me. When I use it heavily (GPS) - I expect it to drain the hell out of battery after 6-7 hours of continued use, and no build would do better, Sense or no Sense. When tethering - it can last towards 10 hours (tethering drain is ~10-12% per hour too). My usage is light, I'm always on auto-brightness, I'm not overclocking, so generally I get the phone to recharge in the evening with half the charge still there - unless I tether for a couple of hours during the day and have several long calls, and in that case I'm charging it 18 hours later with ~20% left.
Ah, and I use customized Royal Panache.

drop the oc kernel and replace with faux enhanced 2.0 1 ghz , setcpu only controls one core at the moment , faux has alittle more work to do on his kernal to get full control of 2nd core so it's not runing at 1300 and burning up battery power
homebase 3.4, update 5.4a , faux enhanced 2.0 1 ghz kernel . battery last for 2 days + 20% left
use setcpu , set up profiles, underclock the profiles
task manager, add most of the apps to auto end list

For me it helped to get rid of market, gmail app, set CPU profiles, alarms, auto syncing, Ebay, juice defender! Google apps seem to be worst offenders.

Battery Life
I had the same problem recently, especially with Faux's 2.0 kernel @ 1.1ghz(1.9 had better battery life :/). Even with Juice Defender(the saint of batter life) I was only getting like 16 hours. My first suggestion is to use 1ghz for standard use, and to create a CPU profile which drops clock speed to 216mhz when screen is off. The difference between 1.1ghz and 1ghz with me was 80% after 12 hours compared to 30%. As I mentioned before, if you're rooted, get JuiceDefender. It has typically gets me 1.4x-1.5x the battery life. That is, even in you're sad case, 6 hours of extra life. Finally, kill Facebook and Browser when you're not using them, they seem to kill battery life.

I don't miss any of it. I check gmail manually via k9 mail , and I can thaw market if I need it. Right now I'm 14 hours with 42% batt.

Cyanogenmod 7 with faux's enhanced stock kernel for CM7. Make sure you have the correct radio and calibrate your battery, another member has already posted the link to that thread. I don't use juice defender or any other task killers or anything like that. Brightness turned to 20%, set CPU profile set to powersave, gps satellites disabled. I'm at 7 hours and 46 minutes with 86% left. This is with 124 texts sent, 1 five or so minute call and a couple pictures taken. If this set up doesn't work for you consider buying a new battery.

How to get epic battery life?

Hey guys,
I see some people here have AMAZING battery life. Some people are getting 4+ hours screen on time with a single charge.
I only get around 2 - 2.5 hours screen on time. Which is good, but not as good as other people.
I am using the latest Paranoid Android ROM, and I have tried many different kernels but battery life is the same with all of them. I tried undervolting, still the same battery life.
All location/gps settings are OFF. The only syncing I have is Facebook syncing every 4 hours. I checked the battery stats, and everything is normal. I checked Better Battery Stats and everything is normal too, no unusual wakelocks or anything like that.
I checked my cpu bin in terminal, and it has been binned as a 'FASTER' cpu.
I have very good signal all the time. Always use WiFi, never mobile data. Bluetooth, NFC are OFF, and brightness is autobrightness.
So after all this, why am I not getting amazing battery life like others?
Thank you!

Because you use the phone and the others no! I have similar battery life. I get 3 hours screen on time.
Try cyanogenmod. For me is the best rom.

Heres a few things that help me:
make sure if your on a ROM that has it to disable cell broadcasts in wireless & network settings.
In Google sync settings, uncheck everything you don't use or can manually sync. The only things I leave checked are gmail, contacts & calendar.
If you've opened maps, make sure to back all the way out of it & swipe it away from your recent tasks screen. Better yet, if you don't need it, uninstall it or use an alternative like mapquest app.
If you don't use Google talk, open it and sign out or uninstall it.
Try not to overdo it with widgets on your home screens. I mean a few is cool, but when u have 5 screens all jam packed with various widgets constantly running & syncing...
I know you said you've tried various kernels, but I honestly found that I got the best screen on time with Franco r86 kernel (just over 4hrs). I'm not a huge kernel fan so I haven't really tried others, but I was only getting just over 3 hrs on stock.

Hey guys,
I see some people here have AMAZING battery life. Some people are getting 4+ hours screen on time with a single charge.
I only get around 2 - 2.5 hours screen on time. Which is good, but not as good as other people.
I am using the latest Paranoid Android ROM, and I have tried many different kernels but battery life is the same with all of them. I tried undervolting, still the same battery life.
All location/gps settings are OFF. The only syncing I have is Facebook syncing every 4 hours. I checked the battery stats, and everything is normal. I checked Better Battery Stats and everything is normal too, no unusual wakelocks or anything like that.
I checked my cpu bin in terminal, and it has been binned as a 'FASTER' cpu.
I have very good signal all the time. Always use WiFi, never mobile data. Bluetooth, NFC are OFF, and brightness is autobrightness.
So after all this, why am I not getting amazing battery life like others?
Thank you!

I use the greenify app to hibernate facebook and words with friends it helps somewhat on battery life

I recently discovered that if I reduce the brightness down to 50% (which is still very BRIGHT), I can get an extra 30% battery life.
Simple, and yet, effective

Turn the brightness down - even 10pct is plenty bright indoors.

Thanks, I have now signed out of google talk. I only have one widget at the moment and that's the clock widget. It's annoying that everyone can get 3 or 4 hours screen on time and I only get 2

Try Eugene's CPU Sleeper from the market. It turns off all but one of your cores while the screen is off to minimize cpu usage. On CM nightly with stock kernel I got 34 hours with 17% remaining and 2.5 hours screen on time til I ended up charging my phone. I run my CPU at 1350 max / 384 min.
Make sure under sound settings all the sound on touch, keypad, etc are all turned off. Each time your phone ticks a sound it uses battery. Also bright display backgrounds will use more battery.
I only sync chrome, calendar and instant upload
good luck

Clock down your device
Use conservative cpu governor or something like that,
Undervolt if necessary
Have a low brightness screen if it's possible

You can also try this, it takes a few days to "learn" your routine then it supposedly starts saving battery. I'm currently in day 2 of learning mode so I don't know for sure how well it works. But it seems to be getting good reviews so far...

I've read the the battery guru app does nothing for your phone whatsoever...

It just turns radios off and shuts down syncing, nothing you can't do by yourself.

Well it basically learns your routines and changes your sync settings, turns WiFi on/off when needed, and various other things you could do yourself but might forget. Kinda like tasker for lazy people so in theory yes it could save you some battery.

All those sounds are already off, that's the first thing I do
Thanks for that app, I'll try it to see if it helps.

I undervolted the hell out of my phone, at one time it was a -150mv undervolt.
Brightness was on auto, I've now switched to controlling it manually to see if that helps

Tried his kernel already a few weeks ago. No real change in battery.

That seems weird
I am completely stock, and set things more or less the same with you (not syncing, no gps unless needed, on wifi all the time) and I could get over 4 hours screen on time on an 18 hours battery life. I believe this phone (chipset?) is really efficient on standby. Does your phone show that it's being kept awake much using the cpu spy app?

Same here... I'm on stock and the best i got was pretty impressive i think. 49 hours with 4 hours screen on time. I waited till the phone turned off by itself Even though i don't get that with heavier use, it's still enough to take me through a whole day which is better then my old phone
My battery saving tips:
-turn off everything you're not using (wi-fi when not at home or office/school, bluetooth, gps, low brightness indoors)
-swype away apps after you exit from them
-turn off the screen when you put it down/in your pocket etc.
-turn off google now
That is everything that i do. No sync disabling, undervolting, underclocking or other tricks

Install greenify app from playstore

That doesn't do anything. Android as a native app killer. On the other side, this would lead to more battery consumption as Android would have to initalize data the next time you open that app. IMHO leave the apps as they are, Android would take care of them and kill them when required.

IMO it's isn't as powerful as tasker, but it's giving some extra juice.
