I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
I have enjoyed using kernels from geeknik, jt and Adrynalyne and have been using them since I picked up my Fascinate since September. I have been using this phone along with juice defender and juice plotter as well, an it has had a great impact on battery life. One thing I noticed back on Di01 was that the standby on this phone was phenomenal. There have been time where I have only lost 3% over 12 hours with the combination of juice defender. However, since I have upgraded to DJ05 and DL09, it would have the same standby for 3 or four hours then precipitously drop 10-15% on standby in around a half an hour. I notice this on juice plotter. I was wondering if anyone else has noticed this, and if it may be something with this rom or a particular kernel. I am running Adryn's 12/30 kernel and I have tried jt's kernels and stupidfast when it was being used as well. I also used Adryn's 12/16 and 12/17 voodoo kernels with no difference. Any takers? I am also apologizing for this being posted in development. Was jumping on tabs between development and general and put this in the wrong section. It's kind of late.
Try a cache wipe and wipe the battery stats too in cwm the kernels themselves are fine and the undervolting will give you better battery life than not
Has to be your phone or battery.
I'm dj05 voodoo with juice defender, on standby for over 3 hours I well lose at most 1%
Newb question. What is considered standby? Hitting the power button thus turning the screen off and locking it?

I have done the battery wipe, but not with the cache. I don't think it's the battery because it was working great before. Had two fascinates with shot batteries and I know the difference haha. I'll try the combo of cache and stats wipe. I thought it was strange too because there should have been nothing short of the screen on full blast and a demanding game that could make the battery draw down like that. I'll give it a few days and see what happens. Thanks for the replies.
You and me both brother. But I don't use juice defender. I'm actually resorting to turning off data to save battery once school is back in session.
I hear ya. What I love about juice defender is that it keeps the data off most of the day and pings the network for data for one minute every 15 or whenever you want it to. I was doing great on it before. I recommend it pretty highly... unless it is actually the culprit for my battery drain haha. I was using doubletwist, but noticed in the logs it was using 45% of my battery some days without me even using the app. Keep a lookout for that everyone. Not an app you'd expect to be doing that.
I am having the same battery issues. I don't think it started after my bump to DJ05. It was definitely the worst when I ran StupidFast 12.20, after rolling back to StupidFast 1.56, it improved a lot. Still not as good as it was in the before time, in the long, long ago.
I did wipe my batt stats, but not my cache, so please let me know if that makes a difference. Battery life is everything.
Well, I'm DJ05 and voodoo, and have had a terrible battery life ever since I upgraded. I just installed juice defender and ultimate juice this morning, and in about 3 hours, I've lost about 12 percent battery... that's with moderate usage, so I'll keep this going and see whether it actually lasts to the end of the day.
Update:
Well, it seems to have actually helped a decent amount... while my phone was idling for about 5 hours, I lost about 5 percent battery. But, under heavy usage later tonight, it went down a lot faster. So, for anyone having these problems, these two programs seem to help, at least while idling.
Experiencing the same issues. Yesterday I went from 76% to 38% in 5 hours with moderate use. Before DJ05 I used to be able to get atleast 15 hours of moderate use on a full charge. Now I get about 10 if I'm lucky. I've tried various kernels. I used to run geekniks on DI01 with no problems. Thought it was voodoo, but since have removed it and am running geekniks 1.54. Not sure what's going on. I'm wondering if it is because I am using the stock DJ05 w/ certain apps removed......

edit: Since unplugging from car charger not even an hour ago, I've lost 11%! I've used my phone just to do about 10 minute Google chat and gotten about 5 emails. I'm almost tempted to go back to DI01......
edit: Unplugged at 10:30 from car charger and now at 31%! this truly sucks. I won't be able to last a day with the phone like this. May have to go back to DI01 and put up with the GPS.....
I have noticed the same since I went to DJ05, what I am running is in my signature, I noticed the other day I was watching a movie with 54% batter left and 1hr and 30mins later I was down to 15% batter power left... is watching a movie that demanding? My screen res is as low as can go on the stock adjuster,
Well I unplugged at 6:30 and I am 75% and it is 3:25. Not that bad, but from 7:30 to 10 I went from 93% to 80% all on stand by. Then 8 went from 80 to to 75 from 10 to 3:25 also on standby. Makes no sense really. It seems to just have random times where the phone just eats battery on standby for no reason. It does tempt me to downgrade and yes, this is not official for a reason. I wish there was something that could be done about it. I don't want to give up my Gps

My phone was down to 9% at 8:30 with pretty light usage. I'm hoping that there is something in the new DL05 build that will help with this. DL05, for me, has been having lightning quick gps lock ons. As quick a my og droid was actually. I just can't give that up though. I have been tracking this for a while, so I was curious to see if others had the same issue. Glad to see that I was able to bring this to people's attention.
My battery sucks as well no matter what I try with DJ05 or DL09.
I'm even running Voodoo5 125mv under-volted

I had absolutely terrible battery using the Stupidfast kernels after 1.54. It seems like most posting about poor battery life are using one of his kernels. I switched to Adrynalynes 12/30 and have MUCH better battery life. Maybe 2% per hour loss on standby and went about 30 hours with moderate use. I suggest you guys try this kernel or JT's.
Edit: Just FWIW anytime you use the GPS the battery is going to be raped. I think I used about 30% in less than an hour while geocaching. I was really shocked.
I am seeing the same thing as KenKeno. The stupidfast kernels sucked my phone dry so I gave up on them back in december. I'm using JT's 12/30 and went 35 hours with light to moderate usage. I don't use juice defender or anything like that either.
One other thing I noticed about the stupidfast kernals was that they tend to slow down the longer you go with out a reboot. Jt's kernals don't feel like they do this. So, maybe just give jt's kernals or adrynalynes (just an undervolted version of jt's kernal) a shot, they feel just as snapy to me. boot times maybe a little longer but that doesn't really matter does it?
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.
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.

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 keep hearing about not all batteries are equal I wonder how true that is. I just flashed the ACS SyndicateROM Frozen 1.0.2 and I am curious to see how my battery life is on the road tomorrow..errr...today at this point.
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%

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.

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..
