On average I get atleast 15hrs on my G2. I underestimated this phone before even owning it. Coming from a HD2 i can honestly say that this phone is a serious upgrade and powerhouse of a phone. Im still running stock, but i have switched in between the most recent builds to get a feel of things. Training your battery plays a major part of getting the full potential out of your battery. Im not running any task killers, and no battery saving apps. just games and regular apps. I like this phone alot. May have to hold onto it for a lil while, and that means alot since i switch phones almost every other month. CANT WAIT FOR GINGERBREAD!!!!!!!!!!!!
#1 Battery-- Nokia N93
#2 But Not Far Behind-- T-Mobile G2
Yeah I have to say that I agree - battery life (even overclocked to 1.2) with this thing p*sses all over my old Desire. I can actually rely on this baby to get me through my day - a feat which my Desire had to be underclocked to 800mhz and/or run on 2G to achieve.
actually that is one of the things ive been meaning to address, im not a skilled coder by any means but there is a script (made for the heroc) that scales your cpu frequency based off your battery remaining. i have it ported over to the epic (my last phone), and was thinking about porting it to the g2 just wasnt sure yet if there would be any interest in it. on the heroc with cm6 juicedefender and the battery tweak i hit over 49 hours of useage. i will be honest tho, even if i do it it wont be this overnight thing i have a bad case of add when dealing with stuff i work on >.>

This can be easily achieved with setcpu by setting up profiles for the battery level. I've hit 2 days using only setcpu on cm6.1.
I love this phone too, but I'm not having as much luck with the battery as you guys seem to be - in particular when I'm connected to 3g on the move. Are you not running sync/sense sync or anything like that? What about htcsense.com services?

I have all my widgets sync to manual brightness on zero, and 3g running all day. I could get a day and a half with moderate use. Heavy use I get atleast 9hrs
Sent from my T-Mobile G2 using XDA App
teh problem with using profiles is that it basically has to reach a certain battery level for it to change, and even then setcpu runs as a app (taking up more cpu process) then the script does
I just got 30 hours of use and plugged it in at 8% but of course it was light use.

HTC Vision S-OFF CM6.1 Stable Oc'd to 1.5ghz on Pershoots Kernel
I get at least 24 hours from my phone most days, with a good amount of use, the only times I have struggled for battery life was when I was playing angry birds for hours at a time trying to 3 star all the levels.
Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?
turn off gps when not need
data when not needed
Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps
also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running
@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks
Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.
I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.
just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery
My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.
i owe setcpu and screen off seting for my battery life
I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.
I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!
My girlfriends Evo battery life is horrible. She mainly just text a lot and surfs facebook. I need a rom to get her battery life to where she can make it at lease 8 hours before having to charge her phone.

A 3500 battery...nuff said
Savage-Mod
I would get Savage mod 1.1 with savaged zen 1.1.0 cfs havs sbc. I've been using it for the past week and it has been great. The texting and phone it self is faster and smoother than any rom i've used and i've been through most. I am currently on 65%, its been unplugged for 8 and a half hours. I understand that others may have better battery live but i'm using my stock battery, which is great cause I saved money and didn't add any thickness. PM if you have any questions.
I'm on Myn's Warm Z with Netarchy 4.3.2 cfs, sbc, havs more. Even with heavy usage (including video streaming and web surfing) my battery lasts a good 10 hours. I can't recommend this combo enough. I had horrible battery life with the stock kernel on Warm Z. Only thing is, depending on her hardward build, you may have to test a couple different kernels.
Easy answer:
EViO 2, SetCPU to underclock to 921, remove sense and use ADW.
Long answer:
To really figure it out, you'll have to try a bunch of diff ROM/Kernel combos for a couple days each.
I would try with CM7, the ROM from "yet another AOSP ginger ROM," Salvage-Mod, Savaged-Zen(Mod) RC2, Miui and whatever sense ROMs you want.
Also, Juice Defender and Autostarts will help you.
I recommend CM7 with a Savaged-Zen ROM CFS- SBC. Even after flashing a new nightly, I avg. 13-14 hours the first day before the kernel is broken in. Best of all Roms that I've tried and I really use my phone (data & mp3). Forgot to mention, I use Setcpu with profiles.

Let's face it: women have a better sense of style than us dudes, and no chick in their right mind would put up with having a hideous cinderblock of a phone. 6mm might as well be an inch when it comes to stuffing a phone into her jeans. In the interest of keeping our women looking fine as hell, let's find software solutions to battery life
To the OP, try this first: go into settings/wireless and networks and uncheck enable always on mobile data. When I was on a stock Evo, this helped me immensely with battery life. Also, uninstall any task killers she has. Check what programs are syncing with the internet too, it's really just data use that eats up battery life with these phones.
Also, post up a screenshot of her battery use screen, maybe we can help figure out what the drain is Even a stock evo running the latest Sprint update should get around 10 hours, minimum, with moderate use like facebook and texting.

so you base your decision off the fact that your wife/girlfriend/friend will be holding your phone and will buldge out of her pocket...maybe YOU should be holding YOUR phone, but hey i guess im weird, my girl might hold my phone, but she doesnt stuff it in her pocket and walk around with it thats stupid, besides my girl puts everything in her pocketbook as most do, keeps the figure , at least thats what i tell her lol
I am running well with deck's rom (the "yet another gingerbread" rom), rc9 now, and the new savaged-zen kernel (1.1). The phone is running really well. I just tried the undervolting script and that made a few reboots, which never happened since I went aosp last month, so I removed that. battery life seems really good though. 1st run through on the latest kernel went from about 11pm last night until 6pm today with pretty good use. I expect as it settles in it should do well.
Juice defender should help immensely if all she does is text and fb

CM7 RC4 with Savage Zen 1.1.0 kernel, Seidio 3500mAh battery will give you DAYS of battery life if you use it moderately to little usage. With a stock battery you will still get over a day easily.
I have wifi on most of the day, live wallpaper (the smoke one), I DONT use any task killer (because it actually slows down my phone), Bluetooth is on and connected to my car whenever Im driving (at least 60 miles per day)
I believe that if I have to use airplane mode, turn off GPS, not use wifi, not use the phone to its full potential then I rather have a cheaper phone and get a laptop...
The screen shots below were made with STOCK battery because I wanted to know the real difference in battery life between the roms!
Note the usage... I listen to music, voice calls...
here is another comparisson...
I really hope this helps you find what you are looking for
Actually, lies, those screen shots were made with gginggerbread 6(which is based on CM7) with savage zen 0.2.something...
The following screen shots were made with the specs I mentioned in the previous post... Its possible that the battery has improved note the 10 hours of usage and only 12% spent and bluetooth usage
hello everyone. I have been using Cyanogenmod 7.1 for a little while now. I am getting tired of it for right now. I am wanting to try something with sense 3.0 and GB rom. Which one's are great and fully working on the Evo? Also do any of them have better battery life?
P.S. I am currently trying out Synergy rom. My friend has the LG phones on Verizon and man they get awesome battery life. 12 hours off the charger and his phone is only down to 73%. He has been making a lot of calls but man my Evo was off the charger for 16 hours and was down to 15% and I barely even used the phone. I hope the Evo 3D has much better battery life, otherwise I may buy an 3500MAH battery for my evo.

ok thank you. Looks like I'll be flashing and testing out roms today, thanks again I will report anything else here.
Alliance Rom is pretty
Evo 4g
MikG-c2.15 is working very well - no issues at all. Battery easily lasts a day with fairly heavy use. This is probably the best ROM I have ever had on the Evo. (and I have tried MANY.)
RECOMMENDED.
I love Synergy and MikG but I can't use them as an everyday rom because of the battery life. With Synergy I watched my battery drop to 70% in like three hours after I had my phone off the charger for a few hours yesterday morning. And I had barely touched the phone! That is completely unacceptable to me, sorry. I need my SBC and HAVS. I wanted to go back to MikFroyo but I have an issue with the display usage (stays at like 90% even with the screen off and not touching the phone) that drains the battery in like 10 hours.
Tried to go back to my Salvage-Mod nandroid but it somehow got corrupt. I almost went back to Myn's twopointtwo but I didn't want something so outdated (still a great rom though). So here I am now using CM7...not the biggest fan in the world but it works and it's giving me great battery life with Tiamat kernel 4.0.5. A little over 20 hours with medium usage.
I don't understand what happened with MikFroyo. I never had the display usage issue before. Then it just came out of no where and stayed like that. I tried going back to 4.5 (which I know for a fact it didn't do that on) and it still did it. Tried switching kernels, nothing. I used to get 25-30 hours with a charge on 4.62, and Salvage-Mod gave me the same battery life. So I'm just hoping that new kernels with SBC and HAVS will let me be able to keep Synergy or MikG as a daily.

Keep me updated. I have been using Syngergy today and battery life is ok. I would go back to CM7 but having all of the random reboots when 4G is turned on kinda got old.
I need my SBC and HAVS,. also, but you DO know you cannot judge battery life right after flashing the ROM, right? You DO know you have to let it settle in for a day or 2, right?
this is with 28% remaining after heavy use
this is with 12% remaining after heavy use (ignore the 28% in the header...)

Hello all
I have been roaming around XDA for a very long time now and I finally made an account because I simply cannot find an answer. I have a samsung vibrant and not the 4g nor can I upgrade(long story). I use my phone when I need it and i text alot. But lately my battery life hasn't been any good, I've tried reconditioning and the whole bit and nothing seems to give me my needed battery life. I am currently using ICS passion 13 RC1 and it works great, when Im not doing anything -.-; When I use it like for the internet or text a lot it drains. I got to 48% in 2 hours one time and thats with limited background processes. I know ALL about the keeping background proccesses and data using apps down so I hardly have any apps installed, which is very irritating at times, I dont even use the facebook app for that reason. I tried many different roms and it seemed Axura had done that best at one point but it was taken down or is no longer supported for whatever reason so I am now in search for a rom that can get me through the day. I text a lot and web browse occasionally. I dont have wifi so i cannot use that to save battery life while surfing so thats out. I would appreciate all the help and will try every rom if i have to lol XD
I appologize for the long message but I am so tired of hesitating to use my phone as a smart phone.
I get good battery life on the ICS Euphoria ROM. Your battery could be shot, you might try replacing it.
Any of the 2.3 or newer roms are going to get bad battery life. Fishmanmod's updating of Bionics has been very smooth and getting great battery life for me.
I find that battery life between 2.2 and ics is pretty much identical for me as long as there are no wakelocks preventing deep sleep. I'm currently on CM9 nightly w/ glitch kernel and deep idle enabled in nstools and have no battery life problems.
You could also look into getting an official 1800mah battery if you really need more juice
ICS Slim hands down the best.

Your issue is Passion. That ROM chews through battery worse than any I've ever used in the 2 years I've had my phone.

Its not just your Rom, I am on the CM9 nightly and noticed ICS ate my battery by noon today. I was down to 3% from 7am. Granted I am toying with it a bit more but I was still at work so I couldnt use it non stop and I wasnt even watching videos or listening to music on it. I have updated the kernel to SubZero 34 to see if that helps.
Chances are, your battery has lost some of its ability to hold a charge. I recommend buying a new OEM battery, chances are it'll increase your battery life by a good two or three hours.
So far, I haven't noticed a significant variation in battery use in various ROMs, I've found battery life to be more determined by the kernel.

On a side note, I destroyed my screen by stepping on it a few weeks ago. Ordered a new AMOLED screen (not the LCD knockoffs) and battery life did in crease by about 3-4 hours. Same OS, same battery.
So I think some excess drain could be caused by the screen, which might explain why some phones had such poor battery and others don't. I also no longer have the "graying/shadow" issue that plagues some of these phone.
So far ive had the best battery life with ICS passion RC2.1 and my 1800mah anker battery
Since flashing CM9 and then putting on the SubZero kernel (34) I did a full charge and decharge to test and got 12+ hours on it with my normal use. So I have to say SubZero kernel really helps out if you are on ICS.
I f you dont mind going back to a 2.2 rom I would suggest trying bionix 1.3.1 fishmanMod or Deranged9 fishmanMod alpha 1 both get awesome battery life especially when mixed with juice defender.
I was also using ICS Passion and noticed a significant degradation in available battery life. I have three batteries so I'm confident it was the From. Until then I had been using various Froyo rooms and all seemed to have better battery life than ICS. I personally felt it was more likely to be your kernel choice that would impact battery life. I just switched to the SLIM ICS from and I gave been very impressed with both the battery and the responsiveness. Same quadrant scores as Passion but it feels so much faster

I haven't taken the dive into ICS yet i may have to try that out.
If you r searching for nice n smooth rom try
[4.0.4][6-Apr]Slim ICS [3.2]

another thing you can do while flashing wipe battery stats only once....then reboot to normal drain your battery till it reaches 1% charge it full widout any interruption and when it reaches to 100% unplug it and do the calibration from any software available in the market I use Battery Calibration Professionals

repeat the process for atleast 3 days in a row and you will feel the difference..hit thanks if it helps
@OP ICS is simply not battery friendly. You're going to want to use froyo if battery life is that important to you.
Or you can build a battery friendly ICS rom and let us know how it all is
The later builds of Cyanogenmod9 I have been on the stock kernel and its going all day with moderate use without battery issues.

Bionix Fishman Mod is the first custom ROM I've ever installed on my phone and it's battery life is AWESOME. I recently added an 1800 mah battery and I've had 24+ hours on one charge with moderate to heavy use. The ROM itself is smooth as glass and no glitches to speak of.
Trying Bionix

I just installed bionix-V FishmanMod Final 3. Fingers crossed. I don't mind switching back to 2.2 as long as I have better battery. However I did notice when I reinstalled ICS before going to bionix that just factory, not even logging into the market. I got 1 day and 7 hours of battery life, granted I did not do much but text occasionally and some web browsing here and there. Is it possible that the android market is constantly checking on stuff or there is some data being proccessed constantly? I do live in an area where my signal is not great for 3g like 1-2 bars.

Alright so after about a day with the rom, I noticed it's just as bad. I am still getting battery drain and yes I have a new battery in so it is not that. I unplugged it from around noon, did alot of working on it with reflashes and little bits of texting and mostly just scrolling around the O.S. im now at 44%. its been about 5 - 6 hours.
Although I have been switching the battery between 2 phones and their battery meter is very different. like a 5% difference so that may be confusing it. Will update.
