Battery life.

I havehorrible batter life and it takes forever for this phone to charge and it overheats. I'm using the andromeda kernal and OC widget. Can someone tell me some settings I should use? Or tweaks or whatever? I'm talking non-commonsense stuff (not stuff like "turn 4g off")

Turn on Airplane mode and leave it on. Tell people to call you on the house phone. Your battery life will improve dramatically.

The radio really sucks up tht much power, huh? :/ I wish sprint used simcards so I can have a reason to lug around my hero for when I'm out for more than 3 hours

Wow, 3 hours huh? I'm at least getting 8. I was getting 15 or 20 hours, but then started putting lots of widgets on my screens and that really killlllllllllled it

I usemy phone a lot. I was spoiled by my hero. I was getting days on a single charge with the same usage, if not, more. I wish I knew what's killing it so fast :/ spare prts says the screen is a majority of power consumption, but I usually have brightness on 0 (its plenty bright enough. It seems brighter than my hero at 50% ).

Is the Running time at 100%? If so, check Partial Wake Usage. Click on whatever's at the top of the list and check it's running time. Report back and let us know what you find.

Battery life

Is there anyway to make evo battery last longer

Theres toms of threads on this, just use search

The usual popular ways involve custom kernals, specific charging routines.
As started above, the most effective way to find out is search the forums because there are literally thousands of post about that already existing
Swyped from a galaxy far far away......

I can get my battery to stay at 100% for 4 hours is I have data turned off. That's 3g or 4g and WiFi. I turn it on when I go to check when I have the time then turn it off again. That's why the power notifications is a must have mod.

Root your phone and install a custom rom, that helps tremendously. Then I recommend you flash a custom kernel from here.

Use Wifi instead of 3g whenever possible. It makes a difference. Turn off 3g when you are at work this way you will still receive texts and calls. It really lasts. I'm on 19 hours with 37%.

I surf a lot on my phone...I mean a lot. I don't even use my PC anymore, and I probably surf the net for at least three to four hours a day (maybe more). Unfortunately, hours of surfing, even on WiFi, kills my battery. However, I have found that by turning brightness all the way down I can almost double my browsing time. It is a significant difference. You just have to learn to tolerate the dim screen, but for me it is very worth the trouble. And by the way, I have tried every trick I could find on this forum...moat made only marginal, if any, improvements. I use warm 2.2 with HTC 17 kernel.
Not much of a hack or trick...I know. But it is honestly worth it, at least for me.

Display always 75% or higher

I don't know what happened but I'm having issues. I cannot get the display to fall below 75% and it sucks because between my EVO stock battery and my extended battery you can actually see the battery life being sucked away rapidly.

I have the same issue, it is isolated to Sense roms. It doesn't happen with AOSP, which is why those are the only roms I can use due to the battery life. We had a thread going for a while with some other people who had the same problem, but nobody could really get to the bottom of it. I reached out to Aamikam but he couldn't really help or didn't want to. I didn't know if a logcat or anything would have helped but no one really answered me. It happens on froyo and gingerbread sense roms, and I never had the issue for a long time but then I noticed it the first time on MikFroyo 4.62. I've tried everything since then but no results.
Only thing to do right now is switch to an AOSP rom, I highly recommend Team Nocturnal's Xplod. Very smooth with Tiamat 3.3.7 kernel and more eye candy than CM7. I would love to be able to use MikG again but my battery literally dies in 4 hours, regardless if I'm using the phone or not.

Alot of ppl seem to think that 75 percent or more of display is bad. Really it isn't. The battery stats need to equal 100 percent. On sense roms that's the way it is and there is nothing wrong with it. Now if your experiencing high.android system usage, that's a problem. As long as everything else is relatively low, its all good
Sent from my PC36100 using XDA App

Its after I installed the new update. Even downgraded to earlier gingerbread and still 75 plus.
Yes my system is low but I can watch my battery meter lower in realtime. Well I guess its time for a new toy.

If your actively using your phone and it drains rapidly that's pretty normal in my experience. But if its draining a lot during idle, check for a rogue running app. Otherwise not using auto brightness is a good mentioned trick along with underclocking with a new kernel should help
Sent from my PC36100 using XDA App

It has to do with the use of a generic power_profile.xml. Neither CM or stock use correct values for this.

You don't get it...this is not normal display usage. I remember what my battery usage and battery life was like before this problem came up and there was a huge difference. Before, cell standby was my highest usage and I could get 25-30 hours on a charge. Then display usage shot up to 90% give or take some, and battery life dropped to 4-8 hours. I can understand if display was slightly higher than everything else, but display is at 75-95% while everything else is under 5 or 10. There is absolutely no reason why the display usage should be that high even when the screen has been OFF the entire time. That's not normal. I have multiple screen shots to back it up.

Someone help me! (BatLife woes)

Alright I wasn't going to make a thread on this because this topic is already discussed elsewhere naturally but I feel my situation is different. All over the place I see people reporting great battery life with ICS.. well mine is HORRIBLE. I just flashed the latest nightly for Pete's bugless. I didn't change the kernel. Everything is stock. Only a few apps installed. Noop for scheduler and ondemand for governer.
The phones been off the charger for 55 minutes and I'm sitting at 76%. Idk what's going on. I've tried so many rom/kernel combos and I seem to get the same exact battery life no matter what. Around 6-9 hours with less than 1 hour of screen on time.
Things I've tried to combat this:
Undervolting
Freezing apps
Restricting background data
Underclocking
Brightness set to auto
And I'm sure a few other things I'm forgetting about. I've done all this and still get ****ty battery life. I've flashed the new radio hoping that it would solve my issues but no dice. My signal strength reports at -67 dbm yet the bars never go over 2. 3g or 4g. Even after updating plr.
On gingerbread cm7 I ran brightness at 70%, ocd to 1.4ghz and always got 15+ hours.
For the love of god someone help me. Cuz I think my phone hates the cream sammiches.

try this kernel, trinity teuv underclocked/undervolted kernel, oc'd gpu http://goo.gl/rY6ga
and do not set brightness to auto, its a battery killer. i keep my brightness at about 20-25%.
also, be sure to fully discharge your battery then charge it completely, after 2 or 3 cycles you should be good.

I do this every day lol I let the battery drain to around 15-30% before I plug it back in.
Screenie: 1 hour later and I lost another 25% this can't be rom or kernel related. As I have tried trinity already and the same thing happens

Ugh. Another 20% gone. Its only been a half hour from the above screenie. You guys see my dilemma? Lol **** me.

i was having horrible battery drain after flashing a new rom & kernel - i finally figured it out that my APN settings were messed up and I re-entered them according to the correct carrier settings.
i don't know if that will apply to you since it looks like your 4G data is working properly, but since I was on wifi 99% of the time, as soon as I went off, my data didn't work. but it's something to look at.

4 hours later I'm down to 4% from a full charge.

I would be interested to see what your battle life diff is without 4g switched on. Also in that 4 hrs what was ur screen on time?
Have you thought of trying a new batt? Just got an OEM Samsung for 5 bucks on eBay. Worth a shot.
Oh remove fb app it blows...install friend caster way better less batt make sure you change the sync interval.
You could also try green power from the market to manage your data use while screen is off.

Ok here's how my battery performs back in cm7 nightly 174 gingerbread. Almost 4 hours and only 25% chipped away. If you look above you'll notice I lost more than 40% in the same time with ics. And I'm doing nothing different. I'm even overclocked to 1.3ghz ondemand with noop for a scheduler.
I think I'm sticking to gbread until official source is out. Maybe then ill get the same battery life.
Sent from my Nexus S 4G using xda premium

That is really weird, if you have time try Milestone 3 and SG's latest kernel and just leave the settings stock . I get wonderful battery life with it hopefully you do to
Oh and are there any apps you are using on ICS that you aren't on CM7?
Sent from my Nexus S 4G using XDA App

Nope. Lately its only been a handful. I actually have more apps installed on gbread to achieve some of the features that are baked into ics. I just don't get it. Ics hates my phone. I even used the GPS today. So weird.

This. If you are installing the same ol battery-draining POS app then you are not going to fix it with any rom or kernel.

So you guys think my batter watcher widget is preventing my phone from sleeping properly? Ok.. I'm on cm7 right now. Battery is def back to normal. And this is with bacround data on. Ill delete bw and get better battery stats.

Better battery stats is not the same thing as other (mostly useless) monitoring apps.

Look. 16 hours on gb. If none of my apps are killing the battery then what could it be?

Camping and battery life

Hello all. I am going camping for 5 days and I was wondering how I can get the best battery life out of my phone on 1 charge. (I won't have any electricity for 5 days)
I am currently using cnote's port of ice cold sandwich Rossi edition. I will be only using my phone for playing music and taking pictures. The phone will be in airplane mode for 5 days.
My question is if its good to idle it for 5 days in airplane mode or shut it down if it won't be used for more than 5 hours? Does it require more power when booting or does it consume less battery power when idling?
Thanks in advance.

The Indian's recommendation is good.
I would shut it off at night. Airplane mode will save LOTS of juice, but nothing saves power like being off for hours. Lol.
You might also consider one of those portable external chargers. They're pretty cheap.

They have campsites with wi-fi? Daaaamn. I've got to find one of those.

Sorry for being brief, if you only need it for 5 hours of just listening to music and reading ebooks, any rom other than sense 4 and stock will serve you well. Underclock so CPU max is 700ish (thats all you need) and turn it off completely if you aren't using it. I also recommend buying an external battery from amazon. Anker makes nice big ones of like $20

I believe he meant there will periods of, maybe, 5 hours where he won't be using it and he wanted to know if it would be better to leave it on for those periods or turn it off.

If you feel like your battery life with that is well enough, go for it then; just because everyone says cm7 will get you the best battery life, doesn't mean your phone will agree. Oh and the play music thing is an app problem.

Pretty much anything non-sense by TDJ. I swear everything I've gotten at least 3 days with use on every one of his roms/kernels.
I've even gotten 2 days on DARKSIDE sense. But it's always a good idea to keep an external charger if you're going to be gone for a while. Whenever I go on a business trip, even though I know that there will be available outlets, I always keep an external charger in case anything happens. Plus, it's always nice to not have to stick around a wall when you're charging your phone and have to use it at the same time.
