Hi. I know there are tonnes of battery related threads out there but I would appreciate if I got some personalized help.
I am running Trigger 3.2 Final with Bali v1.8.4 and the JK6 modem.
I have gone through all the modems available for Froyo and JK6 gives the best battery life for cell and data. No overclocking or anything.
The problem is I get extremely bad battery life on data on all modems. JK6 seems to be the best of the bad. With data off, I can get 20+hrs with light phone usage, but the moment data is turned on, the bat percentage just drops like a rock. If I enable data and browse the net with Opera Mini (no flash), a 100% charged battery can be reduced to to around 30% in around 1 hour. Sometimes more, sometimes less.
If it is the battery needed replacing, why do I get excellent cell life with no data activated. Bali is supposed to be battery efficient, but I am bleeding power. I bought those cheap knock off batteries from ebay and get the same results.
Brightness is on lowest, syncs are all off and email checks every hour I think. Nothing else I can think off can be chewing the battery.
I have calibrated the battery many times and makes no difference. I should also mention that I had worse battery life on the bionix roms.
On battery use,
Display takes up around 83%,
Cell Standby 11%,
Idle 5%
What can I do? Is there an app that will tell me if I should replace my battery or anything. I am all out of options right now
Bali Is The Problem
I just read about this same problem from other users, the Bali kernel eats up a charge cycle extremely fast and has even caused major over heating problems!
My suggestion is to go to a different kernel or change the ROM completely to something less power hungry
it could possibly be the batttery itself, mine did this a while back and replacing it helped, maybe even upgrade to the extended battery if a little more bulk doesn't bother you it's a great option try a different kernel, i use Bali and am not overclocked with the JK6 modem and text all the time at school I then got an iPod touch and stopped using my phone for music and it saves me an average of 30% battery 0_o idk why but oh well

So here's the situation...basically am getting about 12-14hrs of battery life. I have been switching roms, sticking mostly with bionix. However it doesn't matter what rom I still average about the same.
I'm not sure what I actually should be getting so I thought I would ask. I user my phone for basic use; texting, checking email, 30 min podcast, and an app or something. I don't game or watch videos.
Can we here what people are getting and if there is something that can be done to get more life on my battery?

The other dozen threads on the same topic didn't provide enough information?
Use 2G/3G Network Switcher and stay in 2G mode unless you really need speeds faster than EDGE (downloading a podcast). For texting and email, 2G is fine and will help battery life. Also using Juice Defender can help as well.
Go download Auto Killer, and set it to whatever level you want.
Also, go wipe you battery stats.
See if that helps...
Yup I've done all the above. Just curious if I'm still getting what is standard. I've searched the forums but if you know the best place to look then point me in the right direction. Keep the advice coming

12-14 hours is pretty good. Best I got was with Franken-Twiz 3. I think the J16 modem in Franken-Twiz 4 is killing my battery faster so you can flash Modem J12 or try Bionix 1.8 which has Modem J12 in it.
how do you wipe battery stats?
Yeah how do you wipe battery stats

wipe battery stats
Welp with 3g and wifi off I'm easily getting 16hours and on average I'll have 50-70% left of my battery.
I just normally use it as a phone thou. You know some emails, text messages, some surfing.
Just in case you think I'm nuts heres a screen shot as of now. 98% with 3hours on the battery and 48% with 16hours on the battery.
Last night I went to bed at 10pm and my phone was off the charger since 6am and I had 72% on the battery.
I've learned the more you fiddle with your phone the more battery it uses obviously. I've had several phones so I don't have to constantly play with it. Play videos or stream and well it will eat batteries. Use GPS and wifi it will destroy your battery life. Of course I'm not a power miser, but honestly I use it when I need it and when I don't it just sits there until I do.
Got it thanks

I'm getting similar performance with the JI6 OTA, and I generally leave both GPS and 3G on all the time. I just checked my battery stats and my phone's been off the charger for almost 4 hours and my battery percentage is still at 99%. Granted, I've only made two short calls and checked e-mail a few times but I'd call this very good performance. I also woke at 7:30am and surfed around on my phone reading forums and web sites (my display was on for the ENTIRE hour+) for over an hour this morning and when I plugged back in at 8:45 am, I'd used less than 10% battery. I'm also noticing that my phone is charging WAY faster than stock or JI2.
Personally, I have posted about this topic many times but I'm ignored. My battery was terrible before I rooted and did OCLF. After root+lag fix my battery literally tripled in life. I could go 2 days with the same amount of use. Watch videos, surf internet, make calls, do whatever and it would barely use my battery. After this JI6 update I am back to square one. I 'reconditioned' my battery by running it down to zero then charging it back up completely. It definitely helped but I'm still losing a percent by the minute just having the screen on.
Dont waste your time telling me to use juicedefender, turning off wifi, switching to 2g only, task killers, blah blah blah, or any of that crap. I've done it all. I"m still looking into the JI6 radio draining my battery though. Theres a lot of talk about that being an issue.
The JI6 Modem does drain your battery. No doubt about it. I've switched to JI2 and yes my GPS appeared to have suffered a bit and sometimes my Edge connection isn't as good as JI6, but way better battery life.
Or you can do what I do and leave your headphones plugged in and leave the music playing overnight. Seems to make my battery last about 2-4 hours more than it regularly would. Hope that helps

I have uninstalled any battery app because I noticed they drained my battery faster. What I have noticed about the phone, when I charge it with lets say 25 percent still remaining it charges faster,, naturally,, but the battery drains much much much faster. To remedy this,,i use the phone until the battery icon is blank and blinking before I start charging the phone. Naturally, this causes the phone to need a substantial amount of time to charge however the battery doesn't drain nearly as fast. I am a heavy user btw...give it a shot and confirm what I say.

I flashed bionix 1.8 two days ago, charged it up, wiped the battery stats, and let it dry clean.
The phone was in Auto mode for EDGE/WCDMA, reinstalled/downloaded my apps and some more, tested GPS on a few occasions, watched some HQ content on Youtube, and tested VideoPlayer, a few calls, some SMS and MMS, I listened to my music for the most part on it. 30+ hours later the phone finally drained.
With any stock FW's I could not get through more than 24 hours of a regular use with 2G mode only.
Currently I am at 79% at 11hr mark since unplugged.

True. You have to sacrifice something.
Hi everyone, this is my first ever post on the forums so don't be too harsh on me lol anyways, my question is what is the best ROM + radio + kernel combination to get the longest battery life out of my stock thunderbolt battery? Currently I am running DasBAMF 2.0-5 the MR2.5 radio and the dream kernel. I haven't really noticed a huge improvement in my battery life since I flashed this rom a few days ago. I have seen people who claim to be getting 10-15 hrs on one charge. I don't think I need that much because I charge overnight every night, but it would be nice to know how people do that. also, what are your thoughts on juice defender? thanks!
I am currently using CM7 R1.2 w/ the MR2 radio and I get very good battery life. 10 hrs plus with minimal use on the regular battery.
I've been running Gingeritis 1.0 with JuiceDefender Ultimate and I've been getting anywhere from 16-20 hours on the standard battery with regular use (facebook, email, words with friends, browsing, etc.). What I find most helpful with this rom is the brightness slider in the dropdown quick settings. Unless you're outside on a bright day or it's absolutely necessary, keep the brightness as low as you can comfortably use. I've found this to be huggee in the ongoing battle to get better battery life.
And if you can tolerate life without 4G, use an LTE toggle app to keep your phone on 3G. This also helps a lot.
i like the Inj3ctTh3ory rom so far.
It looks to me that all MR2 radios use more battery. The best battery performance for me was on BAMF 1.7 and MR1 radio. I would use 2 to 3% battery on standby overnight, with the phone on 3G. I am on BAMF 1.8.6 now with the OTA radio and the overnight battery usage is up to 10%. I will keep testing, but I think stripped MR1 ROMs have the best battery performance.

BAMF 3.0 RC4, imo 3.4.0, OTA MR2 Radio... constant 40-45 hours on the extended battery.
How I maximized my battery
In terms of my battery I just wanted decent battery life without using a tone of extra apps to do it. I'm using the CM7 RC 1.2 with the MR2 Radio getting about 20+ hours of battery with standard use. I am not using Juice defender or any battery saver apps. I am just using Tasker to turn on and off my Wi-Fi when I'm not at home, because I hate doing manually
One thing I did do to maximize my battery life is after I flashed my new ROM I did the following after searching multiple forums for battery optimization methods
1. Charged my Battery to 100%
2. Did a Bump Charge Cycle 4 times, and then turned on phone
3. This step is probably key. Downloaded the Battery Calibration App. You can find the app in the Android Market.
4. Plugged in the charger until the Battery Calibration App read 100% and 4200+ mV. I found that even after bump charging my BW battery widget would say 100% and the led would be green. However when I go into the Battery Calibration App it would say 99% and the mV would be about 4160. I just plugged it in and waited about 30 - 45 minutes and it would finally be fully charged at 100% ~4200 mV.
5. Press the Battery Calibration button in the App to clear the batterstats.bin and unplug the phone. Do not shutdown or reboot.
6. Let battery drain completely without plugging it in (USB and AC)
7. After it completely dies Charged battery straight until 100% with no interruptions.
I'm getting good battery life without having to use juice defender or anything, and that's also with streaming bluetooth music everyday driving to and from work for a total of 1 hour. I also keep the radio at 3G the entire day unless I really need high speed data. And unless I'm in the car, Bluetooth is turned off. I'm pretty sure these steps should work on any rooted phone regardless of ROM.
I tried many different rom and kernel across the forum... I dun see any differences in term of battery life, just go with the one you love.........weeeeeeeeeeeeeeeee
My bolt gets better life running Ziggy's kernels for some reason. Not sure why, but it does. I've tried every sense ROM out there. +1 on the post above. Go with what works best for you and the way you use your phone.

I've found cm7 (cm7 kernel) to have the best battery life for me, getting up to 28 hours with light use and no 4g. I find the auto-brightness on cm7 to work much better than on any other ROM I've tried, and for some reason all other ROMs drained the battery around 50x faster while idling. I can leave my phone unplugged overnight and expect to lose maybe 2-3%.
There certainly is no universal solution though. That is the only certainty
Whatever rom/s you test with...make sure you try various kernel versions (lean kernels mostly) to find what works the best.
I've tried them all,
GINGERTH3ORY V5.0 DreamKernel is my favorite one. it's super fast and very responsive.
Battery life is best on this one .
I use speedtweak batt saver ondemandx.
I'm on Bamf 1.8.6 remix right now with the OTA MR2 radio and getting about 14 hours on 3g all day and 8.5 hours if on 4g all day. Still looking for something better.
I have had a lot of luck with Inj3ctTh3ory. I have only had it now for two days but I'm already impressed with how long the battery has lasted. I have not experimented with any Kernel/CPU combo's yet but it's performing so well now I might not mess with it.
ROM and kernel linked in my sig. I'm using the 1.4GHz extreme UV with interactivex speedtweak, I love it. Bulletproof stability and with mild/moderate use I can make it through a 9hr work day with 50% left on the stock battery. 4G left on, everything syncs every hour. I don't get 4G coverage at work, I don't know if that helps or hurts, but I do leave it on.
Are there any good ways to extend battery life besides the obvious stuff (no WiFi, GPS, screen brightness, etc.)? I just converted from my iPhone 4 to a Nexus S and battery life is pretty miserable - I can make it through a day but I have to plug in as soon as I get home. If I could stretch that 12 hours to 18 or so it'd be perfect. My iPhone could do 24-36 no problem, so I feel like 18 should be reasonable.
You can try different kernels for your firmware. The custom ones (good ones) normally consume less battery.
You can try to calibrate your battery, as well.
That is if you're rooted. If you're not there's not that much you can do. Install Current Widget from the market and let it be in standby for around 1 hour with WiFi and that stuff off, and check how many mA it's draining.
Other than that, turn auto sync off, and don't let everything send out push notifications (news readers, Facebook etc.) and if you're using a weather widget check that it's not updating every 30 mins or something.
BazookaAce, but having a smatphone like this without being rooted it's a waste of gadget...IMO.
Yeah, I'm rooted and running brainmaster's MIUI ROM. I do have syncing turned on for everything, I'll try messing with that since I certainly don't need FB or Twitter updates every 30 seconds.
just dont use any of battery saver tools. it doesnt work. wipe battery stat if ur phone rooted.
I have a similar problem. I am running an XT860 and am barely getting 12 hours and that's with an extended battery! I have read that keeping the software on your phone up to date usually improves the battery life.
What kind of droid do you have?
Root your phone, install cyanogen or miui.
Download setcpu app.
In setcpu, set it so your phone uses 500-600 mhz of processor speed when the screen is off.
That alone should help your battery life by at least 25%.
Not so sure setCPU is the end all solution here. I have this as well and I have mine actually down to 245mhz when in screen off mode, yet my battery life still is horrible. I have screen brightness pretty low and only gmail is setup to autosync, and checking the stats gmail does not use much of the battery.
I think it also has a lot to do with how good of a signal you get in your area. If your phone is constantly cycling through to get a signal that will eat up your battery as well and is pretty much out of your control.
Dropping the speed with the battery life sucks hd2 setcpu that does not taste at all
hey guys - need an answer to solve my neverending search to this problem
i'm trying to determine the best way to get as much battery power out of my SGSII and i've been experimenting between a SGSII and a Motorola Photon 4G. both phones are running a ICS-AOKP rom, same CPU clock settings, both on "conservative" governor, and both on power save mode..
the only significant difference is with the battery and the kernel, while the photon is running with a stock 1700Mah battery and stock jokersax CM9 kernel while the SGSII had an 2000Mah Extended battery with Siyah 3.0 (with "battery" kernel tweek on)
at the start of the experiment the SGSII had 73% power while the Photon had 48% - i plugged in both phones to the wall and ran a game of order and chaos on both for about an hour and then checked back on the battery power.. the SGSII had drained from 73% to 45% while the the photon 4G had actually charged from 48% to 62%
i've tried a similar experiment with not only AOKP but also CM7, CM9 and MiUi and MiUi V4 and both yield similar results
now my question - if both phones are using the same rom with the same settings practically speaking, with the SGSII being slightly more optimized towards battery performance, why is it that the SGSII's battery will still drain while the photon 4G's battery will still charge?
Wow, i haven't had battery drain like this, give it like 4 battery charges then you'll see whether you still have this problem or not
I can normally get near enough 2 days battery life with medium usage. I'm using the stick battery MIUI GB
wow dude, are u using the stock battery or an extended?
always calibrating ma battery everytime it gets to 100% and it doesnt seem to help much -
Id love if someone else attempted the test by plugging in the phone and having wifi on + run a quick game to see if your results are the same as mine.. the typical response i get from others i've shared my result with is "duh - the battery will drain if ur playing a game while charging, all devices do it" but i have to ask "then why is it that this doesnt happen to the photon 4G?" i remember going on the samsung thread and someone mentioned that the board is set to absorb a charge that is less than how much the Chipset consumes
I get about 7 hours of battery everyday through medium usage and my battery drains quite a lot when I am revising and listening to music. I have a 1900 battery instead of the stock 1650 and it does improve battery life but is there anything else I can do? I find it a bit stupid that my battery drains so much when I'm just listening to music!
I am running CM9.
Whats the signal strength like in your area? Aside from the screen (put screen brightness down), 3g seems to drain my battery most in weak signal areas, where the signal bars are continuously on 1 or 0. I put my 3g / data off and my phone can easily go hours before any drop in battery percentage, I got 4 days battery life with 3g off using it sparingly or wifi when i could to check my emails. Only other thing i did was calls and texts, but that was just as a test.
But i like to keep data on, and gps, all the time. I often get 4 hours screen time and approx 24 hours battery life with my 2000mAh Samsung battery.
Aside from that, last time i checked cm9 was a battery drain, may have moved on a bit.
the only real way you can save battery "during use" is with some restraint. Ie turn brightness down if screen is on, listen at lower volumes if it's playing music. The more voltage it's using the faster it drains. So less brightness or volume output = less power used.
7 hours is around the average use for battery life savy users around here. Even with the extended battery I'd say your right about on the money for battery use (based on what I assume you do and don't know at this stage). But there is certainly room for improvement .
Now before I go on, you probably won't notice any significant difference to battery life during use from these steps. My only hope is that in-between use it'll save more power, and squeeze out a bit more usage time for you.
First/easiest thing would be go to check if it's sleeping properly. Just don't use it for say an hour, then go to the battery monitor in settings. Check the screen on and awake times, they should be almost idenical. If there are several awake records in between screen on's, then you have a problem.
If you use sounds like unlock sounds etc, go turn them all off.. this was/pretty sure still is an issue in CM9 (causes audio_out1 to continuously wake up the phone from deep sleep and drains the battery like a mofo). Also getting rid of facebook (if it's installed) will help.. it loves waking the phone for no obvious reason.. even with every form of sync, background data, and mobile data in general turned off .
^^ you don't have to do that step but I'm pretty confident you'd have to anyway, so it's just easier to do it straight up. Then you can look for other problems.
Next, install "better battery stats". If you like to support developers, you can quickly buy it off the market. Otherwise it's free here if you search for the official thread.
Reboot your phone, then leave you phone for an hour or two, then check out whats happening in better battery stats. I'm not going to pretend I unerstand what half of the stuff it bangs on about is, but I digress. Select "since charged" and then check each different tabs of data (partial wakelocks, kernel wakelocks etc). You are really just looking for anything that stands out as a red bar basically. small amounts aren't a real worry/bound to happen. If it's bigger than say 1cm long, it's probably an issue. Then it's up to you to find out what the app/process is doing the damage . So either google or the better battery stats thread will be your friend at that stage. It was obvious what is was for me cause it said facebook but you might have a different experience.
Hope that helps. But the only way that's going to make a real dent would be trying to use it less.. lol.
Oh and if possible, turning on airplane mode would save a bit of battery in use. And of course the obvious ones like turn of wifi, gps, bluetooth, data, auto sync, soft key backlight and anything else you can turn off
Just do it what i say .. Download the full version of app. called juice defender from play store..install it and then see the magic by yourself ..i have been using the same ..it almost double up the battery backup through its advance settings.
