[Q] HTC EVO -- Best Battery life ROM???

Can anyone tell me which ROM (STABLE) provides the best battery life on HTC EVO???
Thanks!

I have been through just about all on this site and Fresh's newest seems to work best for me. With moderate daily usage I can go without charging for about 22-24 hours. Of course all I need to go is 12-14 b/c I charge every night anyway, but I did leave off charger one day just to see how far I could go. I'm giving Calk's latest a try right now to see how it goes. Just be sure to give whatever ROM you try a couple charges before making a final decision, as it usually takes this amount to get an accurate read on true battery life.

how many of these post are we going to need lol

I know that the latest kernels off the latest build have been killing my battery, it's horrible for my EVO.
But you really have to try different rom/kernel/PRI/radio combinations to find the best battery life for your Evo. I wish there was a preset rating system for each rom though, just to see how things work for everyone else(i.e. battery life, quadrant scores, force close problems, etc.)...but there really are a lot of variables, so I don't think that may ever happen.

Yeah I agree there isn't a clear cut winner. Everyone uses their phone different so it will differ for everyone.
Totally agree to give it a few full charges... I suggest when you get a new rom and/or kernel installed to reset the battery stats (can be done in recovery) then use it till it dies then charge to full before turning it back on.
Personally, I've been using Fresh 3.3 w/ the Kings #6 kernel and not only has the phone been screamin' fast the battery has been good. I'm only on my 2nd charge up though so I still have one or two to go before everything smooths out.

As posted here, the tests showed that CM w/ Snap 7.5 probably has the best battery life - and it seems by a lot.

I'm using the latest Fresh and I just plugged my phone in at 15% battery after 37 hours. I'm pretty happy with that.

Fresh Rom always gave me good battery.. I'm just using the rooted stock OTA and am getting great battery life.

I think it would be a great idea for this kind of stuff to happen. Some aggregated source where everyone can submit their information using various roms, kernels, etc. Whether it be information regarding Quadrant scores, linpacks or battery life. On computer hardware forums they generally have a section dedicated to OCing records with charts listing someones entire setup while attaining the clock speeds. I don't see why a similar implementation can not be done here.

i use Fresh's Rom made my battery life live avg abt 15 hours

Over 40 kernels were tested and benchmarked in 7 different ways, and the results are posted here.
Should tell you everything you want to know, without bringing roms into the picture (since battery life is most affected by the kernel used, not the rom)
edit - looks like I'm a bit late withthat link - I see the thread for that site was already posted above. It's a great resource.

Fresh 3.2, hands down best battery life for me. 3.3 was pretty bad, as was myn's release....which sucks, because myn's rom is otherwise awesome.

I am using Fresh 3.3.0.1 with a baked kernel that is able to over clock. I then have SetCPU installed with profiles for different states of the phone. If my screen is off I have the cpu set to a max of 500MHz to save battery if there are any processes running in the background. I then have my cpu set to 1119MHz when the phone is plugged in or at 100% with the screen on just because I like a snappy phone. Then when the battery drops below 50% I have it return to stock speeds.
I use my phone heavily for things like subsonic, QIK, FB, Calendar, wireless tether, and of course since unlimited data, calling to any cell, and texting I am on it a lot keeping in touch with friends. I also use the sprint nav at least twice a week.
Results will vary from user to user but so far the phone has been on 7 hours and after some moderate use it's only down to around 75% on the battery.
Again this is how I MYSELF use my phone with this rom and kernel this may not be how you use your phone and you may see different results.
What I have done is searched roms and installed them in total I have used 4 different roms. Baked, Cyanogen, Fresh, and Virus. After installing each rom and setting up my phone I made a nand backup of each so I can flash between them as needed to test. I have found out of all of these roms Fresh 3.3.0.1 with a kernel from the baked roms has worked the best for MY daily use.

Best ROM for battery?

What is the best ROM for battery usuage?

Every sense with leedroid kernel...
Sent from my Desire HD using Tapatalk

i use revolution hd 3.1 and its great for performance and battery

I will second that Revolution HD 3.1 makes such a difference to battery life, its much smoother than stock too. Tried CM7 and CoreDroid but they were both a little too battery hungry to be useful.

ROM, Kernel and Radio
I have used LeeDroid HD, Spike CM7 and Android Revolution HD. All with different kernels and radios.
I would think the battery drain has to do with both ROM, Kernel and Radio versions (and maybe more). So it's vital that all the components is compatible. Most ROM devs recommend both a radio and a kernel.
And of cause it depends on all the services and app installed after the flash
Anyway, to you question:
I use the new Spike CM7 build 19 and have great battery life now.
I had problems with no sleep mode on other ROM/Kernel before. (and yes I have tried various patches)

I'm using CM7 latest nightly with mad murdocks battery fix and the the most latest radio and I'm getting 3-5 mA battery drain while in standby (with constant 3g, mobile data and sync on). So I'd say all the roms are quite close to each other when it comes to battery drain nowadays and the battery drain isn't a main concern anymore while choosing between roms.

My friend and myself bought the phones on same day. He runs Revolution and I run LeeDroid. Looks like there is a small advantage with LeeDroid.

i'm using Spike CM7 build 19 flashed with mad-murdock's batfix build7 and my battery life is great

I recommend Android Revolution HD 3.2 for you!
I had 2-3 days of battery with ARHD3.1 all the time!

I'm not saying that it isn't possible as you can get a week out of the device if you just let it run on standby but as soon as you switch the screen on the consumption jumps to at least around 200mA and add a little gaming, browsing etc the consumption doubles from that (not an exact figure). So what I am saying is that it's kind of false to imply that another rom has way better battery consumption if you really don't use it that much. As it has been implied in many other threads that you just can't get over a day out of the device if you actively use it. It's just maths and there is no way around it as 1230mAhs will only get you that far
It is possible to get a few days by using it as a "regular" phone, it is all really usage dependent, and therefore the times are pretty hard to compare.

I am seeing a battery improvement using Coredroid V4 over Coredroid V3.2.
Today I have given the phone light use, about 4 short phone calls, email browsing, some facebook browsing but no gaming and I am at 73% after 12 hrs from full charge.

Combination of Buzz 1.3.8.2. 1.61GHz kernel, ARHD 3.2 with sense and the recommended radio is working great for me battery- and performance-wize. Using On demand gov at 1.22 GHz with 230-460MHz screen off profile.

I did'nt say that it all depends on the ROM I use, but with my normal mobile phone lifestyle and this ROM I get those battery lifetime. It was ment as an example, because on the other hand, if I use my DHD more frequent with playing games and stuff, I don't get around the 24h with a single battery charge, but that's (like you say) ROM independet because of the big display consumption and the 1230mA battery.
I just wanted to state the ROM I use with my normal battery experience for the thread author to test out.
It all depends on the user

[Q] Battery Drain Since Moving To Stable?

Hey there,
I was using the CM7 nightlies for a while, and the battery life was great. However, it seems like ever since I flashed CM7 Stable my battery life has went down. The part I'm finding odd is that it didn't even last 12 hours today and I barely used the phone (especially in the first 8 hours since I was at work). As well, the battery usage shows Cell Standby and Phone Idle combined using over 85% power, which I've never seen before. I want to say it might be some of my apps, but they're the same ones I've been using. In case it makes a difference, here's my setup:
LauncherPro
Trillian
Clock/Weather widget from Fancy Widget
SetCPU on "conservative" setting
Gmail, Facebook, Messages widgets from LauncherPro
Power Widget
Score Mobile widget
None of my sync settings are really frequent, most are hourly refresh, another is 30 minutes. And since I haven't had this problem before CM7 stable I'm still thinking maybe it's something with the ROM.
What I'd like to know is if I should try to calibrate the battery first. And if that's the case, what is the best method to calibrate the battery so the ROM is reporting it accurately.
Thanks in advance

Anyone have any ideas?

Which radio is that?

Always flash at 100%. Then use your phone at least 4 days, as in 2 complete cycles of using until you have to charge it again. Do not change your radio unless you are absolutely confident about the things you are going to do. Chances are you have a custom rom which does not match the radio you are trying to flash, resulting in a expensive ¨presse papier`.

I appreciate the caution, but the current radio I have is the version that Virtuous recommended to update to. Is there a more "Cyanogen-specific" radio?

I got the stock radio and it's working perfectly. 28hours of uptime with ease (and everything on, incl pushmail). No GPS issues, good reception and no static in the background.

when you say use your phone for 4 days (2 completely cycles) until you have to charge it agian... what do you mean exactly? i need to charge mine after like 8 hours...

What I mean is that you should, after you flashed a new rom, drain the battery at least two times and charge it again fully. Or charge at 100%, flash and wipe battery stats after flashing to speed this up a little. Point is, there is no definite daily use. You could (usually not) notice a very small difference in batterydrain after flashing, but be sure it's not because of Bluetooth, Wifi, GPS or some other thing which is accidently turn on. That's why I said to use the phone for 4 days, and 2 complete cycles. I do not use my phone as heavy as you seem to do. Furthermore, I take care not to turn Wifi, Bluetooth or GPS on when I do not need those functions.

Best ROM for battery life

What ROM's are you using and what do you think has the best battery life? I love my DHD but my biggest pain with it is it's battery life, I would love to get around 15 hours of moderate-heavy use out of it, but right now I only get between 8-10 hours of it, I've tried LeeDroid, Revolution and CyanogenMod. Which custom rom do you think is best for battery life?

in my humble opinion i would say CM7... thats after a fresh flash, battery calibration, and one full charge till total discharge (sometimes i like to do it two times just to make sure the bat stats get proper readings)... Maybe its just me but i usuall get around 15-18 hours depending... I would say that i am a medium to heavy user...mainly surf the web, movies, mp3s, text, light emails and of course downloading new roms and themes to flash...
Other than cm7 i find that RCMix and revolution to be pretty decent on battery life
U can always use currency widget to determin power loss and check whats soaking up your power
I'm no expert but so far this has worked for me

i've flashed a few roms over the last few weeks and i must say that they are all pretty decent in terms of battery life. i haven't really noticed one being significantly better than the next.
i can easily kill my phone within 7-8 hours with heavy usage but i can also keep my phone going for about 30 hours with light usage and about 16 hours with moderate usage, using the same rom.
if you asked me, i think it just depends on your style of usage. perhaps this isn't the answer you're looking for but i really don't think there's one rom out there that is going to give you that edge.

If you are looking for battery, use MIUI Freshly squeezed versions...CM7 was my first ROM, I loved it but battery life was terrible.. I could hardly squeeze out 12-13 hours even on low usage..MIUI is great! I easily get 15-20 hrs plus battery on moderate usage(wifi connected most of the time, abt 30 min gaming etc)..I bet if u try u'll see the difference.....

thanks for the replies, I think you're right with how you use it. Going to try MIUI now as well

+1
but i use leedroid_hd_GB_3.0.1

Leedroid's roms always have very good battery life

Also bare in mind the radio you use has a big affect. I used the stock radio from December with Android Revolution when I first flashed it and my battery drain was extremely bad, about 15% an hour. Flashed some new radios and I get at least 18 hours before I hit 30%.

Yup radio plays a very important role.I tried 6-7 different radios before I found the right one.....

If it is not important for you to lose HTC sense, MIUI is nice in spite of the fact that it looks like too much the firmware of the iphone
CM 7.0.0 HAS a bad battery drain but its fixed in the cyanogenmod 7.0.2... now the battery works for a long time.. 24 30 hrs moderate use..
and finally if you are interested for a better battery drain try SETCPU.apk (free for XDA MEMBERS) AND configure your proccessor for a conservative work or setdown de cpu (900 mhz for example)
under my experience with the custom roms leedroid (lastest froyo 2.2.1 with leedroid kernel 2.2.9 at 960 mhz max) was provided the best battery drain

Yup MIUI does look like iOS...That was one of the reason I didn't pay much attention to it at first.
You can always use a good launcher like ADW or Launcher Pro to replace the iOS feel...I personally am a fan of Go Launcher EX...its simple n fast n serves my purpose

ouu!good idea!!! i like miui´s performance but i don´t like his app drawer hahah

Newest Android Revolution HD + matching radio.img and MDJ's kernel v8 and good SetCPU settings makes for a REALLY fast DHD ( 1.6GHz ) and great battery life, a full day with medium to heavy usage from what I've experienced so far.

Used MIUI for the last day, really impressed, except for the iPhoneish feel as been said above. Going to try the setcpu too so I can underclock
I'm using the recommended radio too, which I always make sure I do, I rely on that for improved signal as well, the reception around my place is quite dodgy. Vodafone is Australia's equivalent of AT&T in America in terms of dodgy reception ha

My DHD is now running CyanogenMod7 2.3.5 Nightly and it drains about 1% every two hours idle. I think that's good.
Can anyone make a comparison table?

ARHD 5.2.3............almost 36 hours with regular use here.............24 hours atleast..................

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

Yes exactly, I hate when people post screenshots of their phone getting 24+ hours, I'm there thinking "well obviously they don't use their phone alot". There is no way in hell i could get 24 hours no matter what rom/kernal I use. Im just happy when my phone can make it till I get home at night
