Hey guys, I'm leaving for a hike later this evening, 100km over 3 days and I need to use my Hero to track my exact location.
My question is, what is the best ROM for battery life?
I took the Hero on my last hike which was 30km tracking with MyTracks and running my own 2.1 ROM (see sig) and the battery died after 9 hours.
I DO NOT care what features the build has, I need it literally to be able to run MyTracks with GPS and nothing more for the next 3 days.
I have taken an emergency charger but the battery time that's likely to give me is negligable so I need something that can make the difference between an extra hour or two, or if more is possible it would be really great.
Any advice would be appreciated asap.
Thanks.
Frankly, with GPS on, even if you turn off everything else, theres no way your going to get a standard Hero battery to last 3 days. Take charged spares.

I'm aware of that, but I don't have any spares, not time to get hold of them, you an't just buy the things locally.
I'm looking for a ROM that will give me atleast a bit more battery life than I'm likely to get with my current one and hope I can find somewhere to charge half way (1.5 days) in
maybe modaco's 3.2 ROM? its based on 1.5. the kernel would offer best performance i would have thought. all the 2.1 ROMs have bad battery life so my advice would to be stay away from those.
next time buy this bad boy

Yeh, I'm currently frantically modifying the stock 1.5 to remove Sense etc and see if iI can modify it it to be a bit more battery saving, I don't need 99% of the apps cause I just need it to run myTracks and nothing else.
My concern with Modaco is all the additions and performance increases may not necessarily be battery efficient, and the one and only time I tried ModaCo was a bad experience.
As for 2.1, of course I know theyre not great for battery, I made one (see sig)
im currently looking for a 2.1 that has decent battery performance im on the VillianROM 5.1 at the moment.
might try yours next
sincerely , i dont think that any roms would be able to get you one and a half day with gps.(
what i noticed is that battery drain differed from rom to rom with a couple of hrs between them ( like 3-4 maximum) but nothing like days

Even 3-4 hours is good enough, it gets the last recorded location 3-4 hours closer to where i was before the battery died, I'm hiking so there is only so far I can have gone within that time.
I'v just stripped down the stock Hero ROM and removed all the HTC junk including Rosie and Lockscreen and most of the apps, all of the htc widgets etc. Going to see how I get o with this, I really do like Rosie but will be interesting to see how I get on with this ugly duckling.

the mugen battery is very nice. i even bought one for myself at the beginning but i ended keeping it in my closet. The phone gets too thick and the lovely htc hero just looses its charm
well maybe you could try mcr 2.8 , disable all data sync(even google ...), even disable mobile network ( or switch on 2g). basically you can disable all the phone functions and use it only as gps i guess cause u need it for my tracks only.

I'll definately look into one of these for next time, but I'm leaving tonight so don't have time to get hold of one.

that's the plan, I'm stripping the Stock one atm, I removed HTC_IME thinking it would default to the stock one though and I can't even get to input methods or anything to set it
would using a vanilla android ROM work?

Yeh, most probably, but which ones are light weight and stable (I'll stick with 1.5 builds because theyre official and fully working.)
Like I said I'm currently ripping everything out of the Hero stock one because I havn't been able to find a decent vanilla 1.5 for hero, most of it seems to be for the G1.

you could try aychteesee's vanilla cupcake from here :
http://android.modaco.com/content/h...illa-cupcake-rom-gsm-now-with-online-kitchen/
from what i know, he build it completely from the 2.73 hero rom.

Perfect thanks, looks like just that I need, and by the time I remove all the extra apps I don't need etc, should be great! Thanks.
after you have done that could you then post up the rom i would maybe like to test with out ripping and the only 2.1 rom i find that has goodish battery life is aHero
I would recoment SetCpu or something to keel the CPU running at 245mhz.
This is a age battery saver.

Like he said^^
Use SetCPU or CPUoverclockwidget.
I use CPUoverclockwidget because it can change the CPU speed to 128MHz and also change how fast the phone should be in standby and with screen on.
So I finally got rid of my iPhone 3G (jailbroken on T-Mobile), and got an HD2 instead. I've always liked Windows Mobile phones (and had most iterations), and since now there is finally some capacitative goodness on WM, I jumped on the opportunity.
And I'm regretting it already.
I'm hoping that somebody here has some suggestion that my two days of thread searching, and experimenting didn't cover.
The problem is, yay, .... the damn battery.
I left it on the charger from totally empty to completely full at 2AM. At 8AM, it was down to 85%. Ten minutes of reading e-mails, 74%. The thing is really not usable in this state.
Here are all the things I checked already:
It runs the latest T-Mobile ROM and radio (the one that just came out a few days ago).
Latest version of .NET (3.5.9).
No push e-mail, e-mail checking once per hour, weather checking once per hour.
Strong 3G coverage area, still tried out WMLongLife anyway (with no difference).
Did several cycles of full discharge, recharge.
Always check task manager, not leaving programs running.
Nothing else is set to go online - Live is disabled.
Screen brightness is set at 30%.
All charges done via wall charger.
I read every post I could find, especially fun the ones where people get 4 days of standby, and 6+ hours of heavy use. Short of loading the ARTEMIS ROM, I exhausted all options I could find. And really, it seems like people get decent performance from the stock ROM, so I'd like to stick with that for the moment.
What am I missing?
So frustrating. I can see how this sort of thing would make the average "just user" go run for the Android or Apple hills. No wonder we get stuck with restrictive babysitting technology, when others can't get their **** together. Spend $450 on a phone that can't make it through a half day of reasonable use? Argh!!
Any suggestions would be greatly appreciated.
same here
i have all the same problems my batt just sucks i figure i have to just by a new one
hey man, i was like you at first too. all my mates had iphones (i dislike apple in general) i didnt want one. At the time o2 (uk) didnt stock android phones and i had a sony x1 previously. So, i got the hd2 and...like you said was disapointed.
Changed the rom to a custom one here at xda (hdowners btw) which lasts 1.5 days (heavy usage)...never seems to get 2 full days when i use it alot.
installed a few different browsers (opera 9.7 and 10)
installed morphgear (with some amazing landscape skins)
fpsece (i found time crisis to be the only actual playable game)
coreplayer
and found it a awesome phone...changed my views on it. Try some custom roms and see what you think...usually you will go mad installing themes, skins, apps...just go wild and keep the ones you really like/work in a seperate folder. Then reflash and install the best only...thats how i done it and i now love this phone
good luck, im sure the rest of the forum will give you some advice.
wayandrs: The main thing that will help is by upgrading the ROM even if it is to stock 1.66 (the latest UK one available) then you notice a large difference and even more so with some of the cooked ones. Other things to note are the WiFi, make sure it doesn't be left on (and only turn it on if you need it) it proper drains the battery. Without knowing your habbits with your phone it is very hard to come up with decent suggestions that hasn't already been posted elsewhere.
I can safely say I get 2-3 days use out of my device but then I don't use it all that much (anymore), don't forget as it is a new toy for you, you will keep playing with it seeing what it can do, this will soon die down (as it always does) then it will be better.
there must be something wrong with your device or battery.
mine lasts for about 3-4 days while middle use. i think for such a powerful and huge device, this is more than respectable.
heavy use...mh...i would say it lasts minimal 2 days, sometimes more.
did you write a complain to t-mobile?
DN41
The battery will improve after a week or so .
Note : charging your battery the first time for only 6hours isn't much , the first time that i charged my battery i left it charging for 24 hours.
Updating to the latest ROM and Radio helps .
I have two suggestions:
1) Take your phone back to where you bought it and let them deal with it. I get at least a full day with heavy use which is to be expected from a high end device with a 4.3 inch screen. I spent a few dollars on a car charger and an extra wall charger for work, sorted.
2) If you want help on these forums leave out the useless complaining about what a rotten device you have. I think I speak for many contributors of this forum when I say that these kind of posts are getting old and wearisome. You will be more likely to get polite replies with inteligent suggestions if you simply state the problem without moaning about the horrible mistake you made in being seduced into buying an HD2. I have purchased phones that I simply did not care for. I returned them.
First step: Flash a decent ROM with most of the performance/battery tricks in there already. Many of these ROMs are constructed from the best (often most battery efficient) parts of multiple ROMS.
Touch-X, Energy, Artemis, CleanEx, etc. All are excellent (though I favour Touch-X myself for a great utility/preformance/battery balance).
Second step: Flash a good Radio that works well in your area but also works well with the ROM/has decent battery life. You'll need to research this for your chosen ROM.
I use the Korean radio in UK. Good quality/signal/battery life.
Run it for a few days, charging to full and emptying the battery before recharging to full again. Do this for 3/4 days at least.
Those changes alone got me upto 2.5 days standby and 4 hours usage (thats movie playing for 4 hours with 100% backlight in a hotel room). Good for a smartphone and longer than my friends IPhones.
Other small programs like WMLongLife, adjusting down the backlight automatically, added another .5 days to standby (though not much to active use life).

Yes, sorry I fell back on the usual retoric.
I do wonder though if when someone buys a new 'Toy' that they dont hammer it to start with for the 'joy' and never think of the consequences.
I like you, no matter which phone I own, being a businessman and needing maximum performance have a charger at my bedside (the phone is my alarm) and also connect it to the car charger when driving.
I wonder if many of the people that move up from a basic Nokia phone (or similar that can last a week) realise what is involved in powering all the functions they require?
Please don't quote iPhone as it dunt do half!
try elegencia rom v 8.5 and reply back
I use the stock rom 1.66 from the beginning and check my mail automatically every 30 minutes. Now and then I check some websites and download cabs and use HSDPA/3G and WIFI if available. My battery is 100% in the morning and 70 percent in the evening. Not bad at all. The first 12 times I fully charched the battery during the night.
I use Bandswitch, which automatically disables my connection within 30 seconds. This is the most important and useful tip! You don't need a custom ROM to solve the battery drain issue.

+1 - Lovely ROM
it looks like you have not a windows phone before
Thanks.
Thanks for the ROM suggestions. I'll try a few more days of deep cycling the battery to see if that helps - if not, I guess I'll try a custom ROM.
And yea, to those 'get a life' and 'don't complain about Windows phones' posts, whatever. I've owned Windows Mobile phones since they first came out, and it's just frustrating that the out-of-the box usability hasn't gotten any better to this day. Looks at the cool people that actually manage some constructive feedback - they are who make XDA forums great. Thanks guys!
A new 1200 battery is 15 pounds (the official from HTC) as a backup. I personaly have bought the extended battery 2400 and it is great. The default battery doesn't last the full day for me because I use it constinuosly as mp3 player , brownsing and video player. I mean, you have options.
ROM
I'll be trying the Elegancia ROM.
That is, once I find a ROM with 2.8 SPL that works on my 1024 version of the H2, to reflash mine so I can get HSPL to work to flash.
I've always really liked Windows Mobile for its flexibility and massive base of developers ... on the flip side, I've been screwing around with this thing for several days now, trying to get a phone that can last through a day. Ahhh, the bittersweet experience that is WM.
I get at most 2 days combined cycle out of my stanard battery and i've had my phone for about 10 days. It came with the stock 1.66 rom but i've run through the tips and tweaks threads so the phone ui is faster and a bit more usable. One of those is a replacement task manager that disables smart minimize in favour of actually closing programs. I've also set the weather software to update every 3 hours because tbh you don't need it to be any more often than that. I do use the wifi alot but i do turn it off when i'm not using the phone. i have also noticed with my phone is if the wifi is connected to an access point for more than 5 minutes it will automatically disable the 3G connection and turn it back on when the wifi is disabled.
for the first couple of days i was completely discharging the battery and then charging it for about 12 hours. this seems to have been the most beneficial. i also will not put it on charge unless it really needs it.
hi, from experience, 3G medium usuage.. 4/5 a day.
If you disconect the 3G connection when not using, it will help.
And of course if you go on GSM instead, one day is not difficult..
battery killer :
1) constant 3G activity
2) Watching video. Worst, video on 3G !
3) games, especially the 3Ds ones or high on processing like the Tower simulation game.
4) bright screen
5) bluetooth
From my experience, from a fresh flash, my battery improves as I get to use it longer and longer.
take a look at your data sync like weather and stock and also check the social networking sync.
Heya, I'm going to visit the gamescom 2010 in Cologne in a few weeks. And right now, my Dream is draining his battery faster than you could say uhhm... a really short word. And Cologne is not really close, that means atleast 8 hours of listening to music etc.
So I'm searching for a Eclair ROM with a nice, long battery life. I already looked into the ROM bible, but without real user experiences it don't really persuades me. Or does someone have some advices how to save as much battery life as possible?

Hey Alex, I got usually around 10 hours of battery life using SpeedTeam Eclair, now that wasnt playing music for 8 hours straight. All newer Roms on the G1, Eclair (2.1) and Froyo (2.2) drain battery life and will never last as long as a Donut (1.6) Rom did. I am current using SuperFast which is a Donut Rom and yesterday I got 17 hours before I plugged it in to fully charge and I still had 40% of battery life to go. So I would say if your looking for great battery life go back to a Donut rom.
If you want a rom to show off then an eclair or froyo rom is where its at but dont expect the battery to last over 10 hours of moderate use. Now you could try Speedteam and while traveling there Turn on Airplane mode (which of course shuts all cell/data Off) and you should get a better battery life. But then again you wont beable to talk to anybody or receive txt messages. Hope this helps.
Sorry about the Rom Bible the user experiences part has been lacking but I just dont have the time lately to flash all the roms and test them out, I have requested other users to give me there experiences and I would place it in the post. But yet again hope this helps.

Thanks for the reply, I'm gonna give SuperFast a try and with airplane mode and lowest screen brightness during the train ride, it could work.
Oh and ty for the quick answer D:
Use an app called "setcpu" ($2 on market, free from the G1 apps section). Use it and set the max to 128 or 245. Under 128, you might get music to skip. On eclair I seem to be stable at the lower frequencies so I use 128 to listen to music. If 128 isn't good for you, try 245. This will make your battery last aproximately 50% or more longer.
Also, try amazon.com. I'd be surprised if you have to spend more the $6 shipped to your house for an OEM battery.
$10 for an extended battery.
Adds about 1/4" to your device, but its well worth it.
http://cgi.ebay.com/2300mAh-Extende...ewItem&pt=PDA_Accessories&hash=item2a0345cc94
I already use SetCPU (But as far as I remember it is free?) and while the screen is off, it underclocks it to 128-245 it really saves some battery, but it still isn't enough I think.
I also already thought about buying a larger battery, but my G1 already seems pretty large to me, and just barely fits into my pockets.
I finally stopped trying to get Eclair and Froyo to have a decent battery life and went back to SuperD just before I went on vacation a while back. I couldn't be happier - you forget how fast a G1 can be after you get used to Eclair.

Turn off profile's on set cpu and underclock it while the screen is off. You're going for maximum battery life, not performance.
Been trying alot of builds recently trying to get reliable gps (+ compass) and decent battery life. I really like MDJ's desire HD build nice gps + nav and best of all loving the new sense interface. But as with a few other builds i have tried recently battery drainage has gone through the roof.
To compare to darkstones desire hd build i get 3-8 mA in standby and i can get around 18-22 hours out of the phone. But most of the recent builds i am only managing 8-10 hours max.
I have tried shubcraft 2.0, the latest hyperdroid, the latest MDJ evo and of course MDJ's latest desire hd. All of which have increased significantly in battery drainage. But when i switch back to an older build battery drainage falls in line again.
Is there something i can do to sort it out? As i see a lot of people report decent battery life whereas my observations are totally the opposite.

looked but can only find everything ive been doing ever since android was first developed for hd2. using winmo battery tweaks, setcpu, turning off all unnecessary wireless (wifi, data, syncs) using a android loader + making sure keypad lights are on. only thing new i found was your post about reconditioning the battery to let it know when it is actually full. none of that addresses the 100+ mA i get in standby and neither does reconditioning the battery.
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!!)

So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?

Gingerbread is Android v2.3. Froyo is v2.2.

@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?

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!
