Whacky battery life theory...

OKAY. As many of you know, I used to be pissed about my battery life until I hit the gold mine with one of raven's 800 kernels. Even after trying 10 of them, only recently did one of them hit the spot for my phone. As most know, the higher the battery temperature, traditionally - the higher the battery drain. I noticed that most of the YouTube videos where people are showing off their N1s didn't have cases on their phones. Now, I regularly use two different cases: A seidio snap and one of the gel-like hard/flexible cases. Recently, I have been using the gel one. I also have a friend that I work with whose phone on the same setup and same kernel gets half the battery life that I do and she is using the snap right now. This morning, I flashed Raven's new 800 kernel AND switched my case to the Snap. If you saw my posts, I got roughly 35 hours of light-moderate use and still had 19% left a few days ago on his 800 from 5/04. After upgrading the kernel, my battery was better than stock, but not great (losing about 3%/hour). I just took off the Snap case and am flying naked right now and think I've already seen an increase in battery life. Obviously, it is too soon to tell. That being said, I'm a computer guy, not a physics guy and I don't know the thermodynamics of the material. I can say that the Seidio Snap has a felt lining and is plastic which I think traps more heat. You guys may tell me I'm nuts but I'm posting a poll to see. Now, I know everything is going to be a little subjective, especially the word "moderate"; however, I think most people contributing in the kernel threads have a solid understanding of the general consensus of the word. Sorry if the poll didn't include every option but I'm just curious.

<10 hour battery life is not crap. With moderate use that's what u get.

I considerate moderate use around 30 minutes total web browsing, 10-30 texts, <1 hr of phone usage and a few e-mails. Even the iPhone can go longer than that (and I hate the iPhone). Also, coming from someone now on 800AVS kernels that can finally get over a day, 10 hours is not very good.

I found the difference between nekkid and a rubber/felt case to be neglegable if any.
Conversely I found some apps to be bad about it when it comes to waking the phone for refreshing data or keeping the system awake (or more awake) even after the display is off. My biggest battery gains were in curtailing a few apps. ymmv, best of luck.

10 Hour moderate use is ok.
But i get double that...
Recently testing the GSM Auto (PRL) mod and it seems to boost my phone considerably.
Unhooked it yesterday at 8.00 PM went for my night shift.
At work i have used it for 20 min. Music and 20-25 min of surfing and nothing else. The rest of the time it has been on standby.
Is now almost 8.00 am. 12 hour has passed and is at 73% left discharging.
Here is my hacks and settings:
ROM: CyanogenMod 5.0.6-N1
Baseband: 2.6.24.00.22U-4.03.00.21_2 (unchanged)
Kernel: 2.6.33.2 CyanogenMod [email protected] #1

SYNC is constantly OFF always!!!
Brightness is at 1-13 %, and i just boost it if i need it.
Keep in mind im a light phone user. I mostly use my N1 for data service.

Honestly, I don't think kernel has anything to do with your battery life. At least not much.
I constantly PUSH 2 email accounts (never turn it off), I always have WiFi, BT, 3G and GPS on. I never turn them off. My brightness is at least at 75%, sometimes at 100%.
I constantly check up on Pocket Empires (game) for about 2-3 minutes every 1-2 hours.. do about 10 min calls.. check engadget, browse xda through an app a little..
And I get 10 hours. If I set brightness/sync like you, I'd probably get that battery life too. I got Cyan 5.x (latest), Amon recovery, stock kernel, stock radio.
I'm happy with my batt life, I can always swap to another battery that's always charged on the dock.. but I use the phone to its fullest and never have to wait for gps/mail/wifi.

Didn't think that I'd have to point out that iPhone has a 600MHz processor, 480x320 weak-ass screen and it only has 1 app running at a time?

I agree 100%. (Except I drive an Evo, not an STI)...
I get ~10 hours and that's just fine and as I would expect for this phone.
I am delighted that some people get more, but their experience is the exception, not the rule.

My experience with flashing in the pursuit of better battery life.

So I upgraded my Pre for the EVO when it came out and have been using the same phone and battery since getting it. I found XDA and immediately started rooting and flashing. I started with Fresh and DC when those were about the only options. I use my phone fairly heavily as I am almost always listening to downloaded radio shows either thru a plugged in headset or a jawbone icon BT set. I would say that I averaged about 8 hours of battery life no matter what ROM and kernel combo I tried. This is everything from Fresh, DC, Virus, Warm, CM6, EViO, Evo-NonSense, MIUI, and all of the applicable kernels. The best I had gotten with all of the various combos was a little over 16 hours (with an SBC kernel), which I thought was AWESOME! Needless to say, I used Warm TwoPointTwo (including betas) for a while and touted its look, feel, performance, ease of use, and feature set alongside an SBC kernel.
I ALWAYS keep an eye on the development section for something to pique my interest and pull me away from my current setup. After trolling Lucid's thread for cm7 for a while, I took the dive when the official cm7 nightlies started rolling out. I have been with cm7 ever since. I also took advantage of savage and zendroid kernels and now savaged zen.
The longest I have gone so far is 2 days 10 hours! How? Well...conservative governor on an SBC savaged zen kernel and toggling mobile data off when not in use. Will that same setup work for you? Maybe. Unfortunately all EVO' s are not created equal.
Moral of the story? It takes alot of time, reading, and work to find the thing that works for your EVO. It was a pain to find the right combo, but it is worth all the work.

Thanks for your post. When you got the battery to last over 2 days, it looks like the phone mostly sat there, am I seeing that incorrectly?
I, like you, have tried all different things with the Evo trying to get battery and performance. I am locked on MIUI right now, it gives me the best of both worlds. If you want to try a Sense rom, try Ava's stuff. When I get "bored" with MIUI I will go back to Ava.

God will kill a kitten if you switch from MIUI. You don't want that on your conscience now, do you?

Yeah it really depends on your usage without it the 2 days 10 hours don't mean much. 2 days is no problem if I only use it to make a couple of calls. every 8 hours it only loses 4% charge when untouched with autosync on. The evo battery isn't bad it just takes tweaking like the op says

I get on average two complete days on a charge. With heavy usage I het like a day and a half, with light usage I can go 3 days. MIUI 1.1.28 w/ savage 1.6 kernel. I used to shut off my data too when I wasn't using it but with the MIUI build I'm on, I don't need to.

I really don't trust the battery use(in settings) in CM7 at ALL. I had my phone plugged into my car charger for 45mins on the way home tonight I unplugged it at 7:38pm.
It is now two hours later(10pm) it is showing I have been unplugged for10h55m9s on the posted screenshot. Then if you look at the other screenshot my battery indicator pro is showing the correct amount of time since unplugged.

I've noticed that the battery stats in cm7 do not reset unless you fully charge your phone. Otherwise it continues the count even if you plug a charger in.

MetalHead, do you overclock/undervolt? If so, would you mind sharing your settings? Lastly, have you noticed an increase in browser speeds since you flashed MIUI and tweaked your settings?

I know I need to come up with something. my battery drain is friggin' horrid.
Unplug @ 100%, turn the screen on, let it sit with nothing, pretty much, running in the background and in 10 minutes will be down to about 93%....
Tried several different combos, but all are pretty much the same results...

I overclock at 1152 with smartass governor 98% of the time. Savage 1.6 is a HAVS kernel so I guess technically it is undervolted. I honestly couldn't tell you about the browser speeds, I've been on MIUI since the beginning of November so I really have no clue what the browser speed on a Sense ROM is. Everything is a lot faster with MIUI so I'm assuming my browser speeds have also increased.

This is typical, unless you use an SBC kernel, bump charge your phone, or unplug it exactly when the light turns green.
Any non-SBC kernel will not keep the phone at 100% charge while on the charger. Some will argue that doing so is dangerous for the battery or methods like bump charging put too much wear on the battery.
This is most likely the reason that phone companies rarely have a true percentage shown on their batteries, because they all do this. If we didnt mod to get that real number shown, you would think your phone was acting just fine.
Personally, if I am really going to be using my phone a ton in one day, Ill bump charge it, but otherwise I just accept that its going to drop that first 10% really fast.
The best measure imo of battery performance is how much % you lose when the battery is somewhat discharged, and off. Every phone will drain while you use it, but most of the hours of a day, your phone is off and idle. If you lose 1% per hour, or 5% per hour, that will make a huge difference in your up time per charge.

Unfortunately, mine doesn't stop at that 10%. For instance, mine came off the charger at 5:30 AM at 100%.
By Noon, it was down to 70%, and I had 1 - 3 minute call, no texts and maybe 20 minutes of playing Klondike before work.
I guess I'm gonna have to go SBC. Worst that can happen is I end up buying a new battery, just incase it does so it in.

So in 10 minutes you drop 7%, and in the next 6 1/3 hours you drop another 23% with moderate use?
That sounds like pretty typical battery results to me, thats about 26 hours uptime with a fair amount of use. But maybe others could chime in.

Dude, 5 hands of a card game is NOT moderate use. It's practically no use. Klondike doesn't use data, GPS, etc... nothing, except minimal graphics.
The one phone call literally lasted less than 5 mins, so yes, a phone that drops 30% doing nothing is drastic.

I seem to get pretty good battery life on Myns rom.
I can go at least 24 hours with moderate usage, all on the stock kernel.

Looks like I may have found a little better stability with the Netarchy-Toast CFS 4.3.2 Havs SBC less.
30 minutes of moderate use today and it only dropped 5%

The best battery life I have gotten is from Feb 09 Plutonium.

Miks 4.5 4.2 sbc, gps on updating all every hour call, text, surf, angry birds all freaking day, and get 14 to 16hours every day

MIUI
Wow i have been wanting to try MIUI for a while and i definitely will now.

I'm getting pretty bad battery life with MIUI 2.11 on hw 003. Can anyone recommend a good kernel? I'm hesitant to try the SBC kernels based on the potential battery damage, so savaged-zen is out, also savage-zen seems to have issues with usb mounting.
Is there a link to savage 1.6 CFS, which I've read in a number of threads now is a good one. Speed is not imp, stability, bt+usb working and battery life is.

SyndicateROM Frozen (EB13) - Battery Life Thread

Hey guys,
Just created this thread so we could all have our battery life info in once place and keep the dev thread from getting cluttered.
Please post the following info:
1. Standard or Fully Loaded version
2. Total hours unplugged and percentage
3. Details (percentage and time) for each service
4. And any pertinent details such as apps used (juice defender), or extended batterys
Also, please don't forget to calibrate, airplane bug fix, and kill that drm.
Ex. (will edit with final time)
1. Loaded
2. Total - 8h50m @66%
3.
Display - 55m 78%
Cell standby - 8h50m 9%
Wifi - 6h40m 7%
Phone idle - 7h54m 4%
Voice - 1m 3%
4. Juice defender, setcpu @ 100/1000
Ideally we want to wait for a full drain to post stats but this is just an example. Thx guys looking forward to seeing what you all are getting.

Just installed it will get back to you in a couple of days after recalibrating my battery.
Btw, i hear Juice defender does more harm than good...

Interesting. I think you are right, we are essentialy minimizing out idle drain to a certain extent. However, even activily using my phone it drans slower than stock with this rom. My next run ill try and use it all day to see what I get.

Battery drain
Hello everyone, noob here. I can't post in the development forum on this but it pertains to the battery and charge to a degree. Maybe someone here can help me in some sort of way.
I rooted and flashed the SyndicateROM Frozen yesterday, used it all day and never a hiccup. This thing is lightning fast and props to the dev's but here is the only issue I found. This morning after waking up I noticed the phone was stuck on the ACS android startup icon. I plugged in to charge last night and it's like it froze the phone when it reached full charge. Anyone else experience this?
Thanks for any help that I receive.

I think I read in the dev thread that it's a known problem with the kernel? Or maybe it was the rom... or CWM? anyways the dev's know about it. Just don't charge your phone when it's off.
Battery for me seems to be a lot better than stock, but I'm always charging here and there... today I'll let it run without charging for 4-5 hours and I'll report back. Using a lot of setCPU profiles.

Are you charging it with the power OFF? Lots of people were posting issues of freezing when charging with the battery off --- and I think the probs are related to CWM -- not the ROM. Only charge while the phone is on -- and you should not see problems.

I put on to charge with the power on last night because I had set the alarm to wake me up and it never did so that is when I noticed it. I don't think I've ever charged it with the power off, even when it was stock.
Maybe the dev's will come up with a fix sometime in the future. As for now, I'm happy as hell 'cause this ROM is great.

Did this just happen once? If it doesn't happen over and over, I wouldn't consider it a bug. I have only heard of issues like you describe with the power off.

I'm looking at 12 hours on ACS Frozen on average. I haven't even gotten close to the rumored 30 hours with "heavy use" I think my use has been moderate. My battery use log only only lists display 98% and cell standby 2%. This confuses me. I do more than sit there staring at my homescreen.

How you use your phone makes a difference and while 30h is possible, I don't see it happening with heavy use unless that is little display use. Below is my most recent "heavy use" run. Basically tried to use the phone all day, xda app, browsing, mainly wifi, 0% screen brightness.
1. Loaded
2. 8h7m @5%
3.
Display - 5h33m 95% <- serious display use which kills the phone quick
Wifi - 4h56m 2%
Cell standby - 8h7m 2%
Voice - 4m30s 2%
4. Setcpu @100/1000, juicedefender, 0% brightness
Pretty good considering the insane display usage. With normal use I get over 20h so that just shows how fast it kills your battery. Going to do an "extreme" run next to include heavy cpu use (play emulators all day haha).

You did that with a standard battery? I haven't seen anyone post more than 4 hours of display "time on". That's impressive. Maybe I should try 0% brightness. I have mine at 25%. Are you on "Conservative" on SetCPU?

The 98% means that 98% of your battery use is coming from the screen. Click on where is says 98% and look at see what the use details are (the "time on"). Generally, most people are getting less than 4 hours of display time on with a single charge. The explanation is that some people stretch 4 hours of display time over 30 hours of use. In other words, the people who are getting 30 hours of use only have their screen on 10 - 15% of the time (or less).

Yes, using the standard battery. Setcpu is on conservative. I always use 0% as it looks great (kick it up tp 25-50% outside). I think I was able to get that long of display use due to minimizing cpu usage and other services. All I did is browse in dolphin and use xda app. And, that was pretty much all on wifi. Only change was the hour I was at the dog park on 3g and I recorded a 5 min video.
I bet my gaming session tomorrow will kick it down to ~4 hours

With phone calls, texting, and music player, I average between 16-18hrs. If I start to web browse or watch videos then about 8-12hrs. Very impressed with this ROM to say the least.

1. Standard
2. 31 @ 5%
3. don't have that it was yesterday
4. standard battery, auto brightness, overclocked to 1.2, wifi on when I was at home and 3g at work.
I calibrated the day after froyo dropped. I didn't do the airplane thing and I thought drm was not in this rom. So in other words I didn't do any fancy stuff.
I will note today I tried 1ghz (which is undervolted) with 4G on all day (I have a repeter on my roof at work) and after 14.5 hours I am at 30% with about the same concistancy of usage as yesterday.
Edit: I only have 1 gmail syncing right now. We will see if I get these magical numbers when I put my other 2 gmail accounts and my 3 actice sync exchange accounts on Monday.

I'm getting mixed battery life. The first day on the rom/kernel I dropped down to 79% in 9 hours, with medium use (no web browsing). I was getting 1% drop every 1-2hrs, and thought it was amazing. Today I tried to be really conservative and didn't use it at all and it dropped 4-5% every hour WHILE IDLE.
Anyone else experiencing the same problem? It seems to happen after a reboot to be honest.
NOTE: If I disable data network mode, battery life is amazing,

I'm not sure about my battery life. I charge mine differently than the average person though. I charge it at work and leave it in my desk, because I use it a lot during my lunch break or whenever I get any downtime. When I get home it's usually at about 70%, and it remains unplugged until the next day. I used to have to charge it at home and at work.

Anyone else getting poor battery life with EC05?

I have the device on auto-brightness settings. I will say that the auto-brightness IS pretty bright with EC05. MUCH brighter than other versions. Anyone else noticing this?
I came from EB13 and I got excellent battery life. So far, today, while getting full bars:
Time on: 7 Hours 21 minutes since unplugged
Time on display: 56 minutes (86%)
Voice calls: 8 minutes
Total battery left: 32%. That's a far cry from what I was getting with EB13.
Otherwise, I'm pretty happy with this version! Although, EB13 was awesome as well. I just had a bit more force closes here and there on EB13.

Took mine off the charger around 8am with moderate use mine tanked around 6. I also live in an excellent 3G/4G area.

Any reason why?

Its probably the brightness broham. Try turning it on manual and keep it as low as possible. The screen is the biggest stress on the battery. The brighter the background the worse the battery life as well.

re: waiting a while... the battery gets 'conditioned'... look up one of the MANY threads on that subject on here... some you have to be an astrophysicist to understand, but interesting nonetheless. Re: brightness, yeah, turn it on manual, set it on lowest poss setting, indoors most of the time its plenty bright, and if your ROM didnt disable it (idunno why they would) hold down your status bar and a little drop thingy comes down, slide L or R for brightness, like for outside, or if you really wanna make an EVO user sad and show off the AMOLED mmmmm..... contrast ratio and black levels....

This is some of the best battery life I have gotten out of this phone period. Its so good I dont even want to flash a custom ROM. I have brightness turned down. F that auto brightness..I hate that feature. I unplugged today at 6 in the morning...Played on it before work....Played while at work.....Some more after work...A little while driving...(dont judge me) ....... And now Im on it playing poker online. I love it. Im so serious about not flashing a custom ROM. I am loving this new update and its battery life.

This is EXACTLY my usage patterns and battery for the last 2 days. The only way I'm getting 14 hours out of this thing is if I don't turn it on once. And fixing the brightness isn't going to help me too much if it loses 80% just sitting there idle is it? I'm pretty close to just flashing it back to DI18, declining updates (or flashing the Syndicate rom from that era) and just living with it. For the record, I also had miserable battery with everything DK28 and EB13. Perhaps my phone just doesn't like Froyo?

I know if I am using it off and on pretty constantly I get no more than 6hours with moderate activity (email, web, occasional phone call) we will see what happens now that I am on this ROM.
I told myself I wouldn't go to a non-factory ROM but this is stable, runs the processor with less power @1GHz and with the click of a button you have on-demand 1.2GHz.
A few other things I noticed is the interface is MUCH snappier even though I am using the TouchWiz launcher and the "Fully Loaded" Version I can't wait to see how it goes.

After 2 days on EC05 my battery life is ok, but not as good as when I used a custom undervolting kernel. After 12 hours I'm at about 40%. Today I'm going to try using setCPU to run a different profile and see if it works or makes a difference.

i havent seen good battery life since 2.1 :/ i used to get 24 hours of use with epic experience and the phoenix kernel.
no way im going back to 2.1 just for battery life. although it is the most important thing to me

I have bad battery life with EC05. Tested today with only 3 texts, and two 10 minute phone calls.
8 hours of standby time and I've burned 5.25% of battery per hour.
Wifi on 99% of the time and within range. Policy = never sleep
Same usage for the weekend on DI18 I'd be around ~85% rather than my current 57%.
My battery life is even worse for work days when I have Lotus Notes Traveler sync scheduling every 15 minutes.
DI18 end % of 8 hours of work = ~70-75%
EC05 end % of 8 hours of work = ~43%

Took mine off the charger around 8am with moderate use mine tanked around 6. I also live in an excellent 3G/4G area.

Just to follow up, I flashed back to Bonsai 4.0 and unplugged at the same time today(8AM.) it's now 8:00p and I'm at 66% battery with just about the same amount of moderate usage.

This is EXACTLY my usage patterns and battery for the last 2 days. The only way I'm getting 14 hours out of this thing is if I don't turn it on once. And fixing the brightness isn't going to help me too much if it loses 80% just sitting there idle is it? I'm pretty close to just flashing it back to DI18, declining updates (or flashing the Syndicate rom from that era) and just living with it. For the record, I also had miserable battery with everything DK28 and EB13. Perhaps my phone just doesn't like Froyo?

Take it in and tell the sprint rep. Maybe you could get a new battery for free. if not you may want to buy one.

Automatic Brightness says that it will hurt your battery more then manually setting your brightness. Gosh, no wonder why so many people complain about battery life. No one can read anymore. Seriously, my battery life is the exact same as DI18 as it is on EC05. Learn how to use your phone efficiently.
Also take into account EC05 is Froyo, and DI18 is Eclair. A big difference in how they have to be treated. You will hurt your battery more doing certain things in Froyo then you did in Eclair, one example is Task Killing.
And if you dare to have the nerve to disagree with me, I'll redirect you to "Poor Battery Life" threads from EVERY SINGLE DEVICE on XDA. I doubt every carrier and company is making the battery life horrible, nah just the users.

Does that mean we should NOT kill tasks on froyo?

hold down your status bar and a little drop thingy comes down, slide L or R for brightness, [/QUOTE]
See, thanks for that info. I thought that feature was disabled on froyo builds. Even with you saying it works, its very rare that it works for me. On 2.1 it was so easy to swipe and adjust it....

I'm getting some pretty good battery life with ec05 so far. Right now I'm at 13% battery and here's the usage:
23hrs 39mins
display 78%, 1hr 49mins
cell standby 12%, tws 30% (I still get that bug from time to time, but not always like before)
voice calls 7% 19mins
phone idle 4% 21hrs 50mins
I had odin'd back to di18 and got ec05 ota friday morning, still not even rooted. I keep brightness at the lowest setting and use a black background.

Yes, you should not kill task or applications at all in froyo.

Synergy battery life

I flashed myns synergy rom a couple of weeks ago and have been getting decent battery life. Today my battery life is blowing me away. Going on 11 1/2 hours since being unplugged with my normal usage and still have 22% battery left. Not heavy use by any means but moderate at least. I have never seen this kind of battery life on any other rom I have flashed. Any other synergy users seeing good battery life?

Yeah, I am a pretty light user but I can get two full days

I got decent battery life on Synergy, but its nothing compared to my battery life on my current CM7.1 setup. 20 hours of moderate use and I still have 48% on the stock battery.

There's a great battery guide in the Q/A section, all kinds of tricks. Might find the guide to kernels there too, another way to drastically improve battery life. The new GB kernel sprint released is garbage, try netarcy-toast "brand" kernels

No where near CM7's battery life, but still very much a daily driver. I usually plugged up at around 40% battery after at least 12 hours usage.

Pretty decent for a Sense rom.

I've had my Evo unplugged for the last 2 days and still sitting at 43%. This is with sending about 60 texts, facebooked, got on frostwire for a bit, made like 12 calls, played a couple of rounds of Angry Birds and been on wifi about 95 percent of the time. Never has this happened with other roms. And I have tried a lot. Only thing disabled was 4G(none in my area)

Unplugged Sunday at about 2pm, it's now Tues at noon, I'm still at 49%.
Light to moderate usage since then, about 200 texts, a few short phone calls, and about two hours combined of facebook and twitter. VERY good life for 2 days worth of usage.

I just recently switched over from CM7 to Synergy RC1... I loved when I went away from Sense to AOSP and was reluctant to switch back. But very pleased and battery life I can confirm is excellent for me as well. My only gripe now is that I'm getting the darn unread email count showing up on my home screen icons even though there is no unread emails. I have found online that it is a known issue and mostly seen in 2.3.3? Can anyone confirm that?
Thanks!

I have tried several sense 2.1+3.0 roms, Virus Kingdom revolution, and mik g I have never been more happy than once I began using Synergy. Heck I even devoted a whole post on Google+ about it. Very stable and my battery is ridiculous. I took my phone off the charger at 6:30 am cdt its now 12:15 pm and I'm at 78%. That's with heavy usage. Great job devs.

Seems like people are getting better battery life now that its been out for awhile, aging like a fine wine

When I first flashed I was goeeting okay battery life, the past few days has blown me away. I am used to seeing my battery drop like mad...but it does not do that anymore. I did nothing that I have not done on other ROMs, it just seems to work better after being on the phone a couple of weeks. This will be my ROM for quite some time now!

I'm really trying to get to the bottom of this display usage issue. My display usage stays extremely high compared to everything else. The more I use the phone, the higher it goes. Say if I use the phone a lot, it will be around 90%. If I barely touch the phone, it will go down to 50% but it's still a LOT higher than everything else. And it drains the hell out of my battery. If I barely use it I can get maybe 12 hours at most. If I do use it, I'll be lucky to get 7-8 hours.
It starting happening to me on MikFroyo but it didn't use to do it before. And now I'm noticing the same thing with Synergy. This is driving me nuts because it's keeping me from using my two favorite roms as a daily. I'll post three pictures. One is what my battery life/usage used to look like, one on MikFroyo 4.62, and one on Synergy RC1. I would really appreciate any insight to this.
Edit: It's only these two roms (that I've tried at least) that gives me this issue, and I think MikG if I can remember correctly. CM, Salvage-Mod, and a few other older Sense roms do not cause it.

This is with MikG 1.5, with my usual fairly heavy use.
AMAZING battery life, and 100% stable in my experience.
I have tried many, many ROMs and this one beats all.

no idea how people get battery life like that. i'm lucky to make it a 14 hours~ with similar usage

I was getting maybe 14-16 hours, then I removed the check mark from Always On Data, and the battery life doubled. (again, this is with MikG only.)

let me start by saying that i used to think the same way your thinking untill one of the guys on the synergy post broke it down for me. it's simple, you keep thinking that the display% is an issue but it's only a number and it doesnt represent your actual battery drain. if you hardly use your phone, lets say u make a couple of calls, check some mail and browse the web. well the percentage is correct, your display was on longer than any other application. so it's going to be higher no question. the real question is are you getting good battery life or not? i'm on synergy RLC1 and after some suggestions that i upgrade my PRL, PRi, and wimax. which i did, now im getting great battery life even though my display percentage is still the highest application.

That is only the case if it's maybe a little higher than the rest of the things. It's a percentage of what has used the battery. When the display is at 90% and everything else is at 3% or less, there is a problem. And no, I am getting HORRIBLE battery life. Like I explained, on ROMs that don't have the extremely high display usage I can get 20-30 hours on one charge. The way the battery drains when I'm using it is extremely noticeable. The picture I posted that has been on for 14 hours with 48% left, that's how my battery usage should look. Granted I hadn't used the phone as much as normal that day, it still would be around the range of everything else.

ok, may i suggest that you upgrade all PRI, PRL, wimax etc.. you know all that stuff and give it 2 days to see if that helps. it made a major difference for me..
