Its been a while since I've seen any comparisons on here. Just list how much screen on time, time since unplugged, percentage remaining, avg. battery life. I'm trying to get a good feel for a ROM and kernel that fits my user habits. I spend a lot of time creating home screens, texting, playing droid words. I use Pandora when I can't sleep. The ROM I have is di11i's 5.4 stripped with the rGB-v.4-Voodoo #10. I use voltage control but I still seem to get worse results than most people however, I don't really know the extent of their use.
I just changed kernel from rGB-v.4-Voodoo #10 to I9000 reoriented v2.3.2 01.31.2011. This might help me.
first off if you want beter battery life ditch the oc kernal im on andromeda 2.0 with speedmods t1 series kernal and it honestly is some of the best life ive had yet the other best ive had wwhich was by far the absolute best but didnt suit alot of either of our needs, i mean were talking time since unplugged 40 hours
but my current setup , my best results(moderate use lots of speakerphone , txting gps, home screen switching)
time since unplugged best time 26 hours had about 8 % left
display time was like 85 % i always turn on the screen
and check for txts and scroll through my home screens to make sure im sold.
but avg battery life is about a day solid and right around 70 % it seems to take a while to drain it, but its the first kernal/rom that i ca actually plug in my 3.5mm headphone jack in the car and using only a tape adapter get calls through the speakers yay

Thread with tons of battery stats from different people. One of the most useful battery stat posts I've ever seen.
Ok guys\gals, I have a question that I haven’t seem to find. Right now I’m using CM7 stable on my Nook emmc drive and it works great (Special thanks to all Devs in the Android world that make all is possible). Me and the family are going on vacation at the end of next month and I’m little concerned about battery life on a 5 hour plane ride with my Nook. I know of the sleep bug that CM has and everyone has been working on it but right now I get about day use out of it with normal to heavy use. This is fine because I’m always somewhere I can plug into if the power starts to get low, but now have a little concern since won’t have power. I have successfully converted a few movies using Handbrake and would love to use my nook as entertainment\movies for me and the family while in the Air. So in my testing I haven’t been able to get through a few 2 hours or so movies without the power draining down fast.
Ok with all that being said, it’s my understanding is that the stock ROM with root (Nooter 3.0) works great with Video and has good battery life. Would it be idea for me to just restore to a stock rooted Rom, then create a CM7 SD-Card? The cm7 card would be for my use only till we great back from Seattle. Mainly I’m just trying to keep the kiddos happy since they have never been on a plane before LOL. They LOVE all what my little Nook can do and love watching movies on the bigger 7 in screen (Transformers is Awesome on the Nook by the way). Any suggestions would be great.
Thanks Guys\Gals…
Derek.
Yes, what you propose will work.
I actually have a dualboot on my NC with CM7 as a primary boot; and the stock (rooted) on the secondary partition. (you can follow the dualboot thread in the developer section).
However, while you are actually USING the NC, the battery life shouldn't be terribly different between CM7 and stock. The biggest difference in battery life is while in "suspend" mode, because CM7 doesn't go into as deep of a sleep mode as when in suspend while in stock; so if you are willing to actually power down the NC, rather than suspend, you shouldn't experience any additional power drain while on CM7.
If you still have significantly more power drain on CM7, it is probably because you are overclocking. I have found that shutting wifi off when not being used, being conservative in the screen brightness, and adjust the the processor tweak in the cyanogen settings to "conservative" will help with battery.
All of that being said, I hope to get an external USB battery the next time I need to fly ....
My Nook, running CM7 Stable with screen brightness at 100% and wifi off, uses about 18% of its battery life for every one hour of full-screen video that I watch (.avi files, Rockplayer, mostly). The times that I've flown with it (only once since installing CM7) I usually watch an hour or two of video with internal battery then plug in one of those Duracell rechargeable batteries that you use with a USB cable to power portable devices. Using the rechargeable with a Nook-specific cable (in case that helps) my battery drain per hour of video drops to 10%. On night flights both rates improve somewhat due to much lower brightness levels. Plus, if the Nook is plugged in but inactive (powered on or off) it'll ADD charge 5-10% per hour. One charged 750MAH battery (half the size of a deck of cards) and I'm good for at least 8 hours of heavy use (could go longer, that's the most I've needed).
As jasoraso mentioned, you're really not going to get much better life while using it, if you switch to Stock. Cm7's battery usage is only when usage is suspended as it can't go as deep into sleep as the stock os can.
So even if you move back to stock, you're not going to get better life while watching videos. Your best option would be as both posters before me mentioned, an external charger.
Hi,
I don't have sufficient posts to be able to participate directly in that forum, so have no other choice but to raise my queries here.
I've just flashed over from Overcome "Hermes" to "Jupiter". All's well except that the battery performance is quite drastically affected for me.
I've been reading the improved battery life "Jupiter" gets over earlier versions of the Overcome ROMs, but I seem to be experiencing the opposite.
Already did the batt stat wipe via recovery menu. Do I need to so call "run-in" before it reflects correctly? Even if accuracy is one thing... but dropping 3% just on bootup.... is this typical of an uncalibrated battery?
Appreciate any advise here on what I should do. (Apart from a fresh wipe install )
Thanks
I appreciate the enthusiasm these coding geniuses have in rolling out update after updates in the ROMS yet I am apprehensive about the effect of these frequent flashing on the Galaxy Tab components itself. This includes the battery.
My job involves electronic repair and there is a so called number of hours before an equipment goes for a thorough check(preventive maintenance) say for example 1000 hours on a meter. Unfortunately the galaxy tab (or any tablet) does not have this. So if you frequently do a flashing on your tab you subject the electronic components to unnecessary stress,thereby affecting the life of the components like the battery.
In "normal" everyday use of the tab you will seldom do any restart/reboot of your tab,yet in flashing ROMs as many as 3 reboots is needed. As I don't know how to measure the surge in current during reboot, I can just imagine how high an initial current during startup is generated, thus putting a big strain on the battery.
Unfortunately the battery is not user detachable.
There was an author here in XDA describing himself/herself as an "flashing addict"(or something similar). I would like to appeal to everyone-please don't be a flashing addict.

According to the Tweaks section at the team overcome website, it will take several charge cycles before you notice an improvement after the stat wipe. Try giving it a few days before going any further.
PS Not to question your ability to follow instructions (sometimes we miss things) but did you charge to 100% with the tab off?
Yes, I did charge to 100% with the Tab off.
Now upon reading the instructions once more..... I might have conducted it slightly different from the written procedure.
I unplugged the Tab from the mains, then only booted up and wiped the batt stats before re-booting. Hmmm.... maybe I'll go try booting up while still plugged into the mains, do the batt stat wipe, and re-boot. (all while plugged into the mains). Then only unplug the charger.
Wonder is there any diff in doing so.....
Would definitely try re-doing it with the tab plugged in while doing the stat wipe. And if it doesn't seem to fix it, do go through a few cycles before reverting back to a previous ROM.
It's important to completely drain your battery before recharging it to 100% in order to complete a cycle.
Hope you fix it. Battery life results vary between tab's even if they are used very similarly, I'm running the OVERCOME Jupiter ROM with IMPROVED battery life. I keep my Bluetooth, Wifi and GPS on all the time. I also flash quite often and have not seen a decrease in overall battery life. It seams that each tab is a bit different, hardware wise, than one another. Everything from battery to board it seems is slightly different coming out of the manufacturing process.
Thanks. Will try that out.
But it just seems strange coming from Overcome ver 1.4 (Froyo) which had no batt drain problem.... to Hermes which was better in batt performance.... to Jupiter which I'm experiencing heavy drain.
As I did a NoWipe install, all apps and setting are similar (except the new market app).
I was able to run 2 movies back to back (about 3 hours total) and still have at least 40% life left (usually about 45 to 50%). Now on Jupiter, just fiddling around testing the various features for functionality, plus maybe an hour of NFS (total about 3 hours as well).... the batt drops to about 10% life.
Anyway, I'll re-do the calibration and and give it some time to "settle in". Hopefully, that is all that is needed. (I would hate to have to do a full wipe install... and re-installing all apps)

As mentioned in the Tweaks section, perform the Stat wipe and then two full recharge cycle
recharge to 100% (while the Tab is closed) then drain the battery till it is off then repeat the cycle and you will enjoy it man
Please tell me if you need anything

Viewed purely from an engineering perspective, I'm unable to see any significant connection between the flashing of the ROM and a degradation of battery capacity. Further, in the event that the TAB was connected to a charger during the flashing, I can see absolutely no connection at all! Please help me understand your logic.
Ok Back on topic. PCdumb (dude what's with the username lol). Check your app list. It could a new app you or an old app you updated or an app you didnt use before but you use now that is being a battery hog. A small trick I learned is checking apps running services in the background. Go to Settings, applications, running services and check (why is skype working after Isigned out its not a battery drainer but I hope you got the picture).
Thanks for the advise. That was one of the 1st few things I did to check that there's nothing out of the ordinary running in the background and taking up the juice.
Mine's actually draining alot when in usage. Not too sure about when in standby.... will check later.
If after a few charge cycles and the drain is still bad, guess my only next best option is to do a full wipe, re-stock and re-install.....
I did not get any effect from Battery calibration. As expeced. Anybody did actually?
The background services instead might have an effect on power consumption, I agree. But needs numerous testing...
Batt recal did not give me better battery life. There's no difference in the battery performance after 3 recharge cycles.
My tab can at most get slightly more than 5 hours of continuous usage compared to about close to 7 hours on hermes. This is when i dial down the OC from smartass mode to conservative and also put the min freq to 200 instead of 400 which was the setting i was using all the while.
Doesn't seem to be anything else running in the background. On standby overnight, i only lose about 3% which is not too bad. But when in use, that's where the Batt drains fast. Just for comparison, i only lost 1% at most for overnight standby of about 7 hours when running hermes.
Guess I'll have to live with this if i want the speed and smoothness. Still contemplating whether to restock and do a clean flash.

If you want to confirm that JUPITER is the reason that you are experiencing poor battery life, try re-installing a previous version that you feel worked better for you. Maybe reverting back to a previous version may yield better battery results, and I sure hope so, this way you will know if it's the ROM or other elements affecting the abnormal battery drain.
If you do see an increase in battery life, try flashing JUPITER again, see what the results are. I don't know if flashing and re-flashing will have a negative long term effect on your SGT, I know that I flash every time a new release is out (Stock safe, cooked ROM, Kernel) and if i'm not happy with the release i go back to a proven one by flashing another three times (stock safe, cooked ROM, Kernel) and so far I have not had any (knock on wood) abnormal battery activity.
It's worth giving it a shot (if you haven't already).
EDIT: I know, I know the proper sequence is stock safe, kernel, rom.
after week of using the Overcome ROM i can confirm that the battery performance is between 85 and 90% from the Orignial stock ROM performance
No problem since this is normal as we are using a cooked ROM

I do get 4 to 5 hours of continuous use with overcome Jupiter, mostly browsing the web over
WLAN or umts. Hermes release didn't gave me so much more juice, probably 5 hours.
In the background I have emai push, contacts and calendar sync and some instant messaging apps, if I switch off all that I might get an hour or so more.

Wow, maybe your tab is one of the ones with a battery from the bad batch, and it's finally on its way out. I upgraded from the stock AT&T Rom to Overcome Jupiter, and on Airplane Mode with all stock settings (no overclock or undervolt), mine only drops 1% in standby over 14 hours and I can get about 5 hours of video watching straight with the brightness on max before it dies!

I also been experiencing a major increase in battery drain even after doing a couple wipes exactly according to the tweak guide. I went from about 24 hour normal use down to 6-8 hours normal use.
Checked the services as per your suggestion above and found a couple major battery drainers running. Skype and Yahoo but also Google+. What I dont understand is why Skype and Yahoo would be running even though I had not started either since at least several re-boots ago. I had Skype and Yahoo installed for quite a while Google+ is a new one. Anyway I killed all of them and now and will see what happens next.
Not sure thought that this is all there is to the issue. Recahrging is finiky as well. I can turn off the tab and let it charge all night just to find that it charged to about 70% if I re-plug it might charge to 90%-95% and then if re-plug it might get to 100%. The drain from 100% to 60%-70% is extremely fast and still quite fast from there. On one occasion after complete drain I couldnt get it to start charging at all for about 5-10 minutes. I was checking power, cables, connections and starting to panic when all of a sudden it started to charge.
Any advice on possible reasons or solution woud be appreciated. Not sure I want to go beck to stock ROM and un-root just to take it to service center for repairs.
I also posted this on the "htcone" subreddit:
I'm currently using CM 11, which is not yet stable on HTC One M7 GSM (currently on "snapshot"), and the battery life just kills me, so inefficient. I have an external 16,800 mAh battery and it does a good job eating through that too. 20% from that will give me 30% on the phone if the phone isn't powered all the way off -- that seems like a lot of usage (even if that external battery is used and only half that capacity now). I take measures to help my battery like auto brightness, turn off mobile data or wifi depending on what I'm using, or both to really save, I'm usually on silent, no bluetooth ever, location services always fully off unless I'm driving (rarely) etc. Just being in my pocket with a couple of hours or so total streaming music over LTE during the day the thing is under 20% after around 8-10 hours. A few days ago just a couple hours of music streaming (some downloaded some mobile data, not sure how much of each but still; this was not "screen on" time either) and an hour of web browsing ate 70% of it. It was 100% when I unplugged it around 6:30am and shy of 30% around 11am -- jeez!
I have been starting to think my battery is just worn out, I mean the phone is 2 years old (contract ends a week from tomorrow; it really is). But, what if it's the non-stable CM 11? Maybe a different ROM would help? I don't remember it being like this back on the stock ROM but it's been a while since then, and I remember being kinda frustrated with battery life every since I switched but I never got around to messing with this until now when I am even more irritated. I'm due for an upgrade, but squeezing some more life so I can wait another couple of months to see what unfolds (or change my mind entirely) would be great.
Can someone suggest some more efficient ROMs? I could handle Sense but I prefer AOSP -- whatever gets me more juice though. Or feel free to suggest other possible problems/solutions as well. In my power options in settings where it shows power usage, screen is always at the top with around 30%, so nothing jumps out there either. Thanks for any and all time!

I get the best battery life from Android 4.3 Sense 5.5
InsertCoin HTC ONE v8.1.3 >> http://insertcoin-roms.org/category/devices/one_m7/one_sense5/
It's also not real bad on AT&T Stock 5.12.502.2
I unplug the phone at 6AM and take it to work, normal use txt a few calls some web and emails and I have around 50% battery left when I get home at 3:30. On heavy use days I have about 30% when I get home. I should note my phone is also going on 20 months old.
