What is the best thing to do to keep battery life as long as possible with a single charge?
- kernel setting ? (I am using Calkulin froyo 1.5Ghz version 6)
- some battery saving script?
- some app that I don't know which saves battery life
- And how do i turn low the performance as the battery goes down?
Went to gtabcomb 3.3. really made big difference in batt life. I power completely down at night too.

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.

all roms are gonna be similar in terms of battery life. Battery life really depends on what measures you take to reduce idle usage.
-download "green power / premium" and set it to turn off data while the screen is off
-keep wi-fi, btooth and gps off when you're not using them
-use "setcpu" and create a profile for when the screen is off, limiting processor load
-download "battery calibration" and charge phone to 100%. Use the app.
I do all these things (I use battery calibration after flashing every new rom / kernel/ ect) and on CM7 with a 1.3ghz OC, I got 18 hours of battery life with high usage. I've only used 5% of my battery in 4 hours with little use (mostly idle)
I've tried pretty much every ROM. The one I got the best battery life out of was pi crust 0.7. I'm currently on Aura 1.1.3.8 bloat with the stock att kernel and battery life isn't horrible, but nowhere near as good as pi crust.

+1 on πcrust 0.7 I can can 30hours + on a single charge with moderate use. Over Clocked 1.1hghz and Under volted slightly.
Yeah, I used to be on Picrust and the battery life was really good. I got tired of the stock experience though so I installed Alien w/ theme. The ROM is really good, but the battery life is not consistent. Sometimes it's as good as PiCrust and other times it barely gets through the night.
if you do the things I told you to, the alien rom will get much better battery life. I used to be on alien 4 and got 30+ hours on a full charge
Ninja SpeedFreak gives me by far the best battery life over anything else. 40-50hours. Tried Alien, RedPill, Aura Debloat, Aura Accounts, PiCrust, Froyo stock, GB stock (Bell). Nothing but SpeedFreak will consistently get me more than 20 hours.
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
guys i have been using grif_07 cyanogenmod 7.1 for some time now.....although i loved every portion of it(espically the blazing speed and super fast performance) it was at the cost of battery.....
even if the phone was charged to 100%,the battey would drain out overnight despite it being idle for the whole night......
so i am using stock now.....bettery battery but below avg. on performance.....
best rom which balances out both??
I'm currently using 7.2 (1st version), and with it I use CPU Tuner to config my battery usage... It takes about 24h to drain completely, I use a lot my phone, mainly wifi to send emails and facebook...
Im trying Icecream Sunday2 and its going very well
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
