Another battery life question...

I have a buddy with a droid x that gets RIDICULOUS battery life. What is it that causes such a difference in endurance? I mean most of the other specs basically match up... Is it htc related? Can I get "droid-like" battery life somehow? I'm on fresh 3.3 with netarchy 4.1.9.1 bfs

I havent played much with the DroidX but from what I have read it has a power profile managment on it much like a laptop . I believe that is the part Motorola put in the phone . Profiles like LONGER BATTERY LIFE , or MORE PERFORMANCE . Something Im kinda surprised the EVO wasnt given but I make it thorugh the day on one charge

Are you rooted?

Please keep in mind the apps you downloaded and the widgets you have set-up on your screens. Some apps require to be run in the background eventhough they are NOT used by you at the time, such as Google Talk, Qik, Fring, pedometer, and anything that needs to be "ON"...thats one of the culprit on battery drain you might want to look into.
Having one widget per homescreen is ideal, in my opinion..and learned that by having multiple widgets in one screen, is another culprit in battery drain due to it requiring to work upfront, for example, Facebook widget needs to be on constantly and updated for as long as that widget is there, regardless if you touched/used it or not.
Now, for the MOST OBVIOUS part...turning off GPS, WiFi, 4G, and bs when you DON'T need them, by following hot sexy COMMON SENSE, you should get AT LEAST 3 hours more on your battery. Pure sexy common sense LOL ;-)

Greetings,
I couldn't agree more with all the things you noted in your reply.
I rooted mine, and deleted many apps I don't use, but insisted on starting up
even if I had already killed them in the manage applications section.
But I was amazed at how short the life was in spite of having done that. I quickly
discovered (as you noted) that keeping 4G on, drains the batt.
In fact, for me anyway, it really drains the batt!
Just thought I'd mention it, because it was really surprising to me just how bad
an affect on the battery 4G was - bummer.
--Chris

Mine usually gets between 36-55 hours on a charge (record is 58 so far) with about 3-5 hours of "use" on the stock battery. I don't use it to play games or watch movies, just phone, internet, email, etc - widgets all over the place. Gmail push is always on as well. In fact, I unplugged it last at 10:50pm on the 28th (34 hours ago) and I'm at 48% still.
The biggest thing I've found is download setCPU and adjust the CPU frequency to 245 MHz when the screen is off. That saves a lot. Other then that I keep it at 998 MHz (max speed) all other times. I am playing around with tasker and turning airplane mode on while I sleep, but that seems to have a minimal effect, saving around 2% over 8 hours. I use tasker to turn GPS off unless I'm using one of my GPS-enabled programs, although that doesn't seem to do much either.
I'm running just a basic sense rom with a stock kernel, nothing special. rooted with clockworkmod and that's all I've done rom/kernel-wise.
If you actually use your phone a lot I'm not sure there's much you can do besides get a bigger battery. If you just use it mostly as a phone and less as a PMP or gaming device you should be able to get some nice results.
EDIT: Oh yea, and don't use a task killer (I don't). From what I've read those can actually cause the phone to consume MORE power as services are being killed and opened constantly. Android is very good about leaving tasks open in the background without them consuming power. Opening and closing them constantly is another story.

I wish I could figure this out too. I've been switching between a ton of kernels and roms and can't seem to find anything with good battery life. My phones been unplugged for about 2 1/2 hours and I'm at 53% battery life. No widgets running and just average usage.
Running virusrom and kings #9 and a lot of other roms and battery life is a joke.

So far, the best battery combo I've found is fresh 3.2 with it's stock rom and I returned to it last night. Some say 3.3 is as good or better but I can't seem to get those same results...
But my real question is, why is the droid able to get such great life?

My phone stays basically plugged in while I'm at work I'm running fresh 3.3 and kings#9 I thought they are suppose to get decent life but not mine I even have it underclocked oh well I guess thank god for car chargers and extension cords lol

What I have found to help most of all is to NOT use the Mail app - it drains the battery like crazy, especially if you are popping several accounts. Instead, use the gmail client and set it up to pop your other accounts, and push them to you. This literally trippled my battery life. And it is way faster than the 15 minute intervals that the mail app gives you. Give it a shot, you will be pleasantly surprised.

[Q] What is the best kernals for Cyanogen mod 7 rc4

Hi I've been looking around to find good kernals while running cyanogen mod 7 rc4. Some of the kernals I install like netatchy gives the screen a weird flickering. Can someone suggest a good kernal that's overclockable and stable. Thanks

Netarcys kernel really isn't for cm7 that's probably why its flickering. You should try savage zens latest sbc or non sbc kernel or tiamats sbc kernel both are pretty good. I'm running the tiamat sbc 3.3.4(great battery life) and I'm pretty happy with it.
Tiamat link. Be sure to get the evo version because he does kernels for the incredible also.

In a nutshell, sbc is a method of charging that allows you to "fully"(trickle) charge your battery. Normal kernels really only let you charge to about 90% for safety measures; while sbc lets you fully charge letting your battery completely fill. There's a few threads that talk about it if you search around to get more "details". I've been using them for months without any problems whatsoever. Good luck

Honestly I get great performance out of the stock kernel.

That happens to me sometimes but not all the time. I believe that's still a problem with cm7 in general though. For best results I recommended going to settings/ cyanogenmod settings/ performance/CPU settings then use the "smart ass" governor. It has provided me with the best overall battery/performance. I also have my min freq at 245 and max freq at 1152.

Those are also my settings, I've discovered my evo can't go beyond 1.15ghz without locking up. I've been trying to get to 1.2 but no go

I don't really put so much stock in scores anymore they don't mean anything to be honest. Dirk used to be a score whore but I just removed the apps so I wouldn't worry about it anymore. I came to terms that my scores won't go much higher then what they already were. Just ran 40 mflops and 1220 bench.

Yeah I just like the braging rights, hopefully they can figure how to overclock the gpu soon tho

I just wanna correct this misconception because it led me astray and it took a good amount of research to realize this was wrong.
All kernels will charge the phone to 100%. That's not an issue. What happens is, once they are charged to 100%, they start draining battery again, and coupled with the fact that li-ions inherently lose charge over time, and the fact that most people haven't conditioned their battery's memory by properly charging it, by the time you pull your phone off the charger it's already lost that 10% (give or take).
Trickle charging hopes to fix this by "trickling" a small charge into the battery constantly once it hits 100%, to compensate for discharge, so that it stays at 100%. The problem with this is, it pushes a current through the battery constantly, and that tends to shorten the life of lithium-ion batteries over time. You may get better immediate battery life off the charger, but you'll kill your battery quicker. Come months from now, your battery life isn't going to be what it should, whether you notice it or not.
If you want to minimize the discharge, you can take a couple safer steps:
- Condition your battery. Charge it to a true 100%. This will mean turning the phone off and on a few times while it's on the charger to make sure it's actually at 100%. Then completely discharge it until the phone cannot turn back on. Do this a couple times in a row, and repeat every month or so. This conditions your li-ion battery's internal charging memory so it knows its true charge potential.
- Charge your phone while it's off. It won't drain nearly as much battery this way, so when you're ready to take it off the charger it'll be much fresher.
- Avoid prolonged charging and continuous charging, because it can confuse the li-ion's internal charging memory. Rather than re-charging it when it hits 60%, let it drain as low as possible before you bother recharging it. Bursts of short charges don't harm the battery, but they make it "forget" how much it can be charged.
In short, SBC kernels are bad for your battery.
---
Also, Savaged-Zen 1.0.1 BFS no-SBC has been the best kernel I've found for the Evo 4G. Granted I haven't had this thing that long and there may be another gem lying around somewhere, but given the popularity of SZ, I doubt it. It's a very good, smooth kernel. It's giving me the best performance of what I've tried (most of the popular ones).
As for CFS vs BFS, flip a coin. Some will swear CFS is smoother, others will swear BFS is supposed to be smoother. BFS gives me more responsiveness personally, but I think it mostly depends on your workload. I keep scarcely-used tasks killed and I don't use widgets, so the lack of many processes may be what makes BFS better for me. Try both and see which feels smoother in daily use.

That's a great plan man. I visited the savage zen kernel thread earlier and some are complaing about their newest build causing charging issues or something along with 100% wake time idk. If you give it a shot use their 1.0.0 instead of the 1.0.1. Just give the kernels about a week and see how well they hold up. Its mainly about personal preference(sbc or non sbc) I'm actually testing the tiamat sbc but I was previously on savage zen. I like to give all kernels a chance(1 or 2 weeks) to see how well my phone performs with them.

Ok well ill just wait till Friday to install a new one then and see how the Zen works out

Phone feeling hot

Hey guys, I had my phone for no more than an hour. Rooted and flashed cm10. Phone seems to get warm like 100 degrees f. And that's not using data or WiFi.
I had stock on for a little and noticed the same thing, is my phone jacked or is this normal? I have warranty so if none of you guys experience this I'll take it in. I just don't think it's too healthy for the device...

My phone gets pretty hot sometimes too, but only during heavy usage and multitasking. If you're finding that it's heating up when you're just browsing the web or installing apps, try using another kernel. I recommend Lean Kernel with CM10

My s2 barely gets hot :/ and thats with no back cover on just a case. but the battery temps are much lower as well on the S2. usually around upper 70s to lower 80s degrees farenheit under normal load.

yeah
my phone does the same it sometimes does the same it gets hot on the bottom back part

Personally I believe it can be rom/kernel related too. Usually it doesn't get really warm for me except under load. But with the latest leak, if im using it at all, it just stays warm. When I was first using it this morn it actually got pretty hot and when charging got even hotter. I let it cool and hasn't been that hot since.

Well in my life of hacking phones, under/overvolting seriously reduces life of the CPU.. i dont quite feel comfortable undervolting my brand new galaxy s3. lol. Unless someone can provide scientific evidence to undervolting not causeing long term harm to my CPU.

No reason to undervolt or overclock this hardware. Overclocking became irrelevant when dual cores came out. Undervolting was never relevant. People do it because they like to play around with their hardware, which I understand, though I've always been more interested in software myself.

What are you doing when the phone gets warm?

Mine seems to get hot as the battery gets low (not even on the charger).

Juice Defender - Should I keep using it?

So over in a Development thread I mentioned that I use Juice Defender Ultimate still, I got some heat for it because it's old.
What's new that I should be using instead? Running CM10 11/30 Nightly that I v6 Supercharged (Die-Hard, so I don't think Tasker will work).
I don't need anything to sync or notify me when it's in my pocket, just calls/texts via radio. I also already use CPU Sleeper and it's locked in memory via v6 bulletproof.
My goal is to make the most out of my battery.

not sure exactly. i used to use green power battery. these data killing apps used to work miracles on gb and froyo. but nowadays i think the main battery killers are the hefty processors. i now focus on kernels and governors and whatnot to save battery. i think killing data will help if it stays off most frequently. when you have the settings to turn on data as soon as the screen turns on, the device is toggling data and constantly searching for signal, maybe even killing more battery than saving.. idk thats just my opinion. and on the other hand.. if your not really using your phone so much i think it would save more in the long run. i would just test it yourself and see what works

Only thing that will improve the battery is a new phone .
I've tried everything. The best result has been ditching AOSP and going back to TW. It might not be fancy schmancy, but it functions and has marginally better battery life (at least in my experience).
Good luck on your quest. I'll probably keep my eye on this thread to see if there are any new suggestions (but not very optimistic).

Sorry but no one can say for sure whats a rock solid combo. I suggest you try them all like I have to see what works best for you. After trying everything I came back to Ondemand and felt it gave me the best results but thats me.
Good app to try is Llama and its free and does all JD stuff and more

to add, regardless of what kernel i use sometimes the processor will climb to unnecessarily high frequencies when the screen is off. to tame it a little more use setcpu and enable profiles. my profile, when the screen is off, is min 384 max 540 and conservative/noop. then when the screen wakes, interactive/noop 384/1512. but im sure most of you already know this. cpu sleeper will do the trick too. beware of wake lag

I no longer use Juice Defender and, for me and my set up, JD did not have noticeable impact.
Nor did more complex strategies using Llama.

Super hot battery.

According to my dash clock widget and my toasted face, my battery reaches some super high temps. Just hit 131° F. Which has prompted me to post this since this is the hottest I have seen or felt.
Does this usually point to a battery issue, I know the galaxy s2 I had was prone to battery issues. Or possible hardware issue?
Thanks everyone for your thoughts!

Yup. As soon as I plug in the charger it goes up to about 104°. After 30 secs or so of use, its above 120° and stops charging due to overheating. This has just started happening as of late. Happens on both my stock and extended batteries.
Any ideas?

Some ROMs run very hot for some reason. Are you on Carbon? It seems to be the king of white-hot temperatures. Under clocking and undervolting should ease the heat a little bit, but I'm not sure what else you can do.

I noticed that AOKP with all stock settings tends to run a bit hot for my GNex. I've tried Paranoid & XenonHD, both run a bit better temperature wise

maybe kernel problem.
flash other kernel (fancy), wipe cache-dalvik and fix permissions.
with fancy kernel; charger in deep sleep battery:80° F, cpu 90° F. hardcore(benchmark) battery:95° F, cpu:120° F.
with ak kernel cpu:160° F and battery:120° F

For me the stock rom and aospa have been the coolest literally with AK you can set up the kernel in any way you like speed demon that eats thru batt. and runs hot OR cool and smooth thats easy on the batt. and temp.
You should check with another batt. :-S it might be possible that your batt. is borked
