[Q] Battery lifetime on official OTA Froyo ROM release?

Hi
Any news on how long battery last on the new official release?
Im currently on Pays ROM, and battery last between 24-48 h, with 3g and wifi turned on and daily use of phone, sms and browsing.
Just tried some ROMs that didnt even last a whole day

In 3 hours I have nearly used 50% of battery and that is with 3 short phone calls.
System, cell standby, wifi and phone idle account for 80% usage. Was using a different froyo rom before putting oem one on and did not have this type of drain.
Also not using an app killer as people have been saying that the system can handle the apps, that has not been the case and will install again.

My battery drain has been up massively since I went to 2.2 with the OpenDesire ROM. Phone standby takes most of it. What's causing such excessive usage? Even on the official ROM now :-/
What ROM's are you guys getting best battery with?

You should post on which ROMs you have the battery drain...

I have had massive battery drain on all ROMs until I started using the rooted 2.2 OTA. I would have to charge my phone twice every day but now it's great, I have 65 percent left after a full day of heavy use.
Edit: tried almost every FroYo ROM before this.

Which ROM are you using? I can't decide which one to download
Battery life is also my only problem with this otherwise amazing phone

Maybe it's the rom/radio combination!?

I had PaysDesire v2.3 before installing the OTA 2.2. The battery with PaysDesire with average use went from 100% to like 60% in 12 hours. With the latest one, i lost 8% in 2 hours but with over average usage. Testing the camera, installing apps, setting up things...
That is why I am still not convinced that the battery sucks on 2.2 and I will wait few days (until the shine wears off, as Coldplay would say) before bringing my final decision.

i have also been using this rom and found the battery to be great been using it on and off through the day.
wifi tether, engadget web browsing, email couple of calls texts. i work in a phone shop so i use my phone to demo so it has been ran through it paces.

yep ,I now about
you use OTA officiall not ruted

Doesn't you guys' phones' display use most of the battery? For me it's at least 70% of the battery usage.
With SetCpu I use about 1% battery on standby, but as soon as I use it, it drains battery like crazy, even though the brightness is set to 25%...

I am using this one http://forum.xda-developers.com/showthread.php?t=741775
I took it off charge at 7 a.m. an have used it quite heavily today and the battery is still at 50% so I am pleased.

8 Hours and im on 68 %
2 Hours 3D Gaming and browsing 1 Hour.SmS/Few Calls between.
Official 2.2 Froyo ROM.
Wait for Kernel Sources and i think Battery Drain will fall and fall =)

I'll second that. Definitely getting better battery performance on ieftm's ROM than any of the 2.2 ROM's I've used before including Neophytes's, DeVillain, and various others. I've also got much more memory too.

you win the prize for the 1000th desire user posting in the wrong section. The moderators are probably going to win their 100th prize for not moving threads/warning people. And we'll just end up with the 10th thread about battery life scattered in every place.
that aside, no rom or os version has changed a fig for me about battery. It's still good in reasonable terms.

+1.i am getting really good battery performance on this ROM.
but from my experience even from WinMO you will never find a single ROM on which people would agre on 100% that is good or bad.everyone is getting different results.everyone has different apps instaled,using different combination of services (push mail,wi fi,3G...).
Someone will always claim good battery life and others will say it is crap.this is really about testing what works for you the best.
Sorry for my english guys...

When i have a good connection then my battery is ok. After 16 hours i have still 12%. If my connection is bad (i'm in a building) so it search for connection and lost it again i see the battery drain and my battery is empty after few hours...

Anyone found out what kernel works best with it for battery life. The kernel it comes with isn't that great on battery life. Sorry if this was already posted.

Unfortunately, there are no definitives, and if you aren't getting good battery life with the stock kernel with warm2.2, you might want to start looking at some battery tweaks.
There is a thread over in the Evo 4g General forum, the title is "2.2 ultimate kernel review :: Updated 11/6/10" and the OP is skydeaner. His site also has one of the battery "fixes" if its not holding a charge correctly.
Unfortunately, I can't link to it, since I'm still a newbie poster, but, some of the higher rated ones are Kings #11, and the new Net 4.2 kernels.

Im having good luck so far with Nets 4.2.1 CFS more aggressive smartass universal.
There were a lot of people complaining about the awake time of the 4.2 build, so Net tried to tweak the 4.2.1 to have the great sleep time of 42 with the great awake time of 4.1.9
I havent had the phone awake alot today but with light use I have gone from 100% at 8 am to..... 75% at 10:30pm This was no browsing or games, just phone for about 5-10 minutes and maybe 5 minutes of texting only 1.25 hrs awake time total so far.... so very light use today. But ive NEVER had the phone stay 75-80% inot the evening.
I REALLY hope the awake performance is as good as the sleep performance. We'll see how it does tomorrow under some stress.

Just for a baseline, I just put my phone back to root to take it back, I've lost 50% over about 26 hours of moderate texting and usage with just JuiceDefender running.

I have Kings #11 and my battery blows. I drain 25% in less than an hour with moderate use. This is off topic but when you enable your 4G does it automatically turn off on you. I think my 4G is broken and just want to know. I may need to reflash it.

im runnin it with stock kernal and i have no complaints. I just took a screenshot showing like 43% left off charger for 14 hours and talk time was like 1hour and 23 mins. Plus iv used it to play mabey half hour of games and half dozen text. Il see if i can get the ss posted.

Rom and kernel help!!!

I'm in a dilemma! For the last week I've been hunting around to find the right combination of Kernels and Roms. Natively I'm a CM ASOP man. But I've tried everything from CM to MIUI to Ava to Mym. None of the roms are giving a decent amount of battery life. I've tried several combinations of Kernels also. My battery life has been as terrible as 3 hours. I'm talking about losing a percent every minute!
I didn't buy an extended battery. But I have tried a brand new regular battery to make sure that I didn't have a bad battery. Both batteries have the same results under all combinations of Kernels and Roms.
I've seen members braggin on having 12 to 18th hours of life under heavy use! How is that possible!? Lol! I know it has to do with device, kernel, rom combinations.
Can the awsome members of the GREAT Xda please help me out? Point me in the right direction. fyi: I have a ver 003 device and also I don't overclock much at all but I underclock to try and save a lil juice!
Thanks in advanced!

No matter what rom/kernel combination I run I get really ****ty battery life with the stock red HTC battery. For me personally investing the $70 or so for the Seidio extended battery on Amazon was worthwhile. I also purchased their wall charger as well.
I'm not going to blow smoke up your ass and say that the battery last 2 days with heavy use because thats BS. However, with heavy use (running emulators, gmail sync, occasional bluetooth for wii mote, texting, web browsing, etc) I can get through a 9 hour work day with a lil life to spare.

At least go on amazon and get a1800 mah battery. They are cheap but goood.

I just bought another stock battery and a wall charger, I keep the spare in my wallet and battery life is a non issue now.
Check out batteryboss.org before buying an aftermarket one though, most of them are rips offs.

I'm not sure about rip offs on amazon but certainly ebay..i bought two batteries w/a charger for $25..and a third one since my oem battery took a bath, fully charged.

I'm going to research some better batteries. I appreciate the intel. But my thing is I know I can get a few more hours of battery time with a simple kernel modification. Loosing 1% a minute is unheard of lol. Like now: I had 100% when I started this reply and I'm officially at 95% as I press Submit lol! Terrible

You should see if you can get a replacement battery from sprint. I am using CM7 nightly 24, and can easily sustain 24+ hours with the OEM red battery.
Everyone will have different results even with the same rom/kernel, however the drain that your experiencing does sound like your battery might be going bad.

I see your stats and that sh*t is wicked! I used CM7 and that one drains the quickest lol.... before I cash out on a new extended battery where's an abundant source of Kernels? I've tried three and I wanted to do a little process of elimination before I pull out my visa lol
Sent from my PC36100 using Tapatalk

There aren't very many CM7 kernel's available yet, so few that I can't even begin to tell you where to start looking, for Sense roms though, search for Netarchy those kernels work really well.

I see... I appreciate that! Imma give Mym a try with a few of them Kernels. Thanks again for the help
And what exactly is the Kernel that you are using!? Lol
Sent from my PC36100 using Tapatalk

Honestly, I've found that the right kernel makes the biggest difference and setcpu, juicedefender, etc only make it worse. For me (also 003 hw) kings kernel and htc # 15 uv have been best. I've had great success with azrael and vaelpak roms. Currently on vaelpak with kings # 11 with NO battery saving apps. I get 24 hours with my regular use. Yesterday was very light, I went 24 hours with just under 50% left.

This is what I've been testing for a while. This build contains auto bump charging based on the voltage as opposed to the full charge method. I don't know how it works on extended batteries yet...but works pretty good on stock batteries. With this, you should have a better chance of picking up the phone at higher voltages.

I flashed the ver 8 with CM6. 1.2. so far I've gotten slightly better battery life. 20 minutes and I'm still on 99%. That's a whole lot better than losing 1% a minute lol! I'm still going to do another exhaustive research to pinpoint the best combination!
Sent from my PC36100 using Tapatalk

I know you guys said that setcpu can make matters worse. Is it alright if I use it to underclock to 245x245 when the screen is off and if the battery ever goes over 110°F automatically? That's the only profiles i use to help with battery maintenance

If your still using CM7, it has its own built in setCPU, I have mine set to ondemand 245min, 768max, and sorry for the delayed response, I went to lunch, however the Kernel I am using for my CM7 flash is just the stock kernel that comes with the initial build if CM7.

Incredibly RE -engineered questions

So I've flashed over to incredibly RE-engineered and I heard about the great battery life and speed. I sure did have a more noticeable speed improvement but my battery life hasn't gotten any better. Any reasons why this might be? And for some reason I can't load any videos off hulu either. Anyone have these similar problems?

Everyone's battery life is different because everyone uses their phone differently. One person may get great battery life because they don't do much with the phone, and someone else will try the same, but they do a lot of streaming, web browsing, etc and have horrible battery life. It's all trial and error until YOU find the combination that works well for YOU.
And the hulu problem I believe there is a fix for it in the thread. Search the thread for Hulu and you should be able to find it. (I am not sure of this because I don't use the rom, but I believe I read something about it when I tried it out.)

Battery life if tough to compare due to reasons above. When I was syncing a corporate email account via active sync I was getting 9-10 hours o this rom. I am no longer using active sync and right now am at 15 hrs 37 minutes since unplugged at 62%. Awake time is about 5 hours on this charge. This is with stock battery.
Exchange active sync is a hog.

I use my phone pretty often and Im usually texting and browsing on the net. But my battery life is maybe 6 or 7 hours? I haven't really gone all the way down to empty but that seems about right. Is that decent?

I'm not sure what's wrong with my phone. My battery usage says that most of my battery is being used by cell standby and the android system. Should I reflash the rom and see if that helps? I want incredible battery life too this battery life is pretty much the same as a stock rom which is why I flashed in the first place : more battery life!
Sent from my ADR6300 using XDA App

I'm not a power user but I get better battery life with this ROM. Yeah, maybe you should wipe and re-install the ROM. I would then not install any apps and see what your battery life is like. Disable auto-syncing too. Maybe you have an app sucking the battery down.

Is there an app that i can download to monitor my battery usage? I know you can check it through the "About Systems " menu but I almost don't trust it.

Running a faster rom like re engineered, if battery life is super important, you can use setcpu to underclock slightly at all times, and lot at screen off. It comes with a lou's kernel, which he doesn't recommend using setcpu with, but I've always had great luck with king klix kernals, which also undervolt.

Better battery life out of an extended battery?????

I have an extended battery (2600). I was wondering, what does everyone do to get the most out of their extended battery if you have one? I'm hoping to get tips and or tricks from my fellow EVO users. If you have nothing positive to say, please don't post.. Any help is appreciated.

I use the stock battery on my rooted Evo and it lasts all day.

It really does depend on weather your rooted or not cuz on my stock battery I can go about a day in a half maybe a couple hours less MAYBE but then I have a Seidio 3500 mAh that can go exactly 2 days 1 hour and 38 minutes with heavy heavy use and also on a charge of 93 percent
So again are you rooted?

Will give that one a go. I dled it a few days ago but i accidentally deactivated my EVO lol luckily i unrooted it and got it back to root just now so im going to give that one a go

Any stock kernel will not charge any extended battert correctly. I experimented with this for the last month.
I found an app called boot manager and now have 4 roms installed on my phone. At night I boot into a Froyo ROM with a SBC kernel and charge it, then in the am, boot into my Gingerbread ROM.

Yep. If I don't use my phone it will last all day and lose about 1.5% every two hours. I just recently switched to my current setup and am still not used to it. I'll unplug my phone at ~95% and head out the door. I'll pull it out of my pocket a number of hours later and see that it's only down to about 93% - 92%. Before I switched my setup I would've been down the low 80's if not lower. When I use it my battery depends on what I am doing with it and what I have my scaling set to. Using my phone for things like texting, facebook, email, and some web browsing on Skyfire, which is what I would consider heavy use, it goes down about 3.5% per hour. Yesterday I went to my little niece's dance class and I used my phone to record video of her entire 60 minute dance class. Battery went down about 30% percent from that but that's to be expected. I remained out of the house for another 8 hours after her class and my phone still had 50% battery left by the time I got home. Wireless tether eats up my battery. But Thats because I am usually tethering while texting and testing launchers and such on my phone.
I do all of this on a stock battery. So I can only imagine how much I'd be able to do with an extended battery.

I get 30+ hours on my extended battery 2600 from sprint. LOL on warm 2.2
