Battery drain problem

I did updated all roms that you guys post on 'Hermes Mobile 6'. I would say that everything goes very good but the problem is battery drain decrease very fast. Any suggestion about this problem?

When you say all ROMs, have you tried different Radio ROM's? Different radios can have a big impact on battery use; only way to find out is to flash one, use it for a few days. Helps to have Battery Bar which monitors power consumption as well. The latest is not necessarily the greatest. Sometimes it's best to use an older radio ROM. Trying out is the only answer
Hope this helps

Let it drain all the way to null..so you can't even turn it on. Then charge up fully and it should last much longer. Or flash only with 100% on battery. I've had this a coupla times with new flashes on 60 or 70% battery. I'll drain it down and charge it up and battery life is back to normal.

What u mean drain? 2-3 hrs less or more? My battery life is normal it doesn’t mater witch ROM I’m Flashing. Do as Scrog saying is good idea

I think I know what jcute means...
My dopod is occasionally going from a full charge to empty sometimes during the night. I *think* it only occurs when Edge is connected (I haven't really studied it thoroughly).
If this is the same problem, a full charge will not help.
I'm currently using radio version 1.40.30.00. I'm going to try upgrading it to see if it improves the situation. jcute: which radio rom do you have installed?

[Q] AARRGGH!....Battery on my Evo stinks!

Configuring this thing for good battery life is exhausting. Before root I had done most things listed in this thread : http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/ and finally achieved pretty good battery life.
After root, I have never been able to achieve this even though the bloatware isnt running, have various tweaks on there for performance, and so on.
Have tried Fresh Rom with stock and Kings #11 and liked it but had terrible battery life. Tried Myn's 2.2 with stock, Kings #11, and Netarchy and battery was not much better. Now running AVA9 (no flashed kernel) and battery is no better. Have tried running setCPU on all these setups and does not help.
Any suggestions? Seems someone will say this rom/kernel combo works for them and another person will say it sucks, don't use it.
I couldn't stick with Myn's because there were too many bugs/errors. If my best bet is to go back to all HTC stock rom w/root then so be it.
.....and yes, I have read through the numerous amount of threads on this topic but no clear combination has been highlighted that I have seen. I use my phone for business primarily so it needs to last me as long as possible. The thought of increasing my phone size with an extended battery is not appealing to me.

I have stock rooted 3.29. I initially did the plug-unplug trick when I got the phone. Then, I turned off always on data, and set email, google accounts, and Sense weather widget to update once an hour. Phone behaves the same as when data is always on, so I don't even notice 3G off when the screen is off.
I get 8 - 10 hours under very heavy use (constant fiddling, email, games, internet, calls, etc),
10 - 15 hours moderate (surfing, ebooks, email, internet),
and easily 18+ with light use (email, occasional light surfing, occasional call)

I have everything the same as before root so with the bloatware and some other things not running would think it would last longer than stock......not!
@greyopaque...what was the reasoning for using stock rom instead of custom? Battery life or just never tried any of the others? Would like to know if your battery life is better with just the stock over others.

Ditto....I am a heavy user and leave everything running that I need. I use the phone for what it was made for. After trying/not trying all different types of roms/battery tweaks/advanced task killers/battery monitors etc., I decided to buy another original red 1500 battery as I don't like the extended battery look either. So, until they come with better battery technology....I guess that would be the career to go into and make some money ;0).....we are stuck with the best phone ever...yet....with a battery life that sucks for those of us that put the phone to the test....have a great day!

Yep...only problem is having to shut the phone off, change battery, then power back on. All the while, missing whatever phone calls come in.
***My point of the thread really isn't the terrible stock battery but the fact that the pre-rooted setup lasted so much longer than the rooted w/custom rom. Why??
I would think the battery life would get better without all the bloatware and other worthless services running all the time.

Once again.. you need to check your apps. Most likely there's something causing a drain.. Try updating to the newest rooted stock roms (3.30). The new kernel is definitely an improvement.
As an aside.. what bugs did you have with myn's 2.2 rls2? I ran it, and it was fine. Now on rls3 beta and amazing rom with great battery (3.30 base).

To be honest, I've never tried anything else. I really like the stock Sense experience... and since this is a work phone, I need it to work without glitches.

Well....hopefully I can hear from some peeps that have used a good amount of custom roms/kernels, as well as the stock one and see what they think.
Cmon guys....let me know!
@eyeballer1......Myn's was just acting weird and I kept getting a "com.htc.bgp" force close that I couldn't fix. Also, I have tried the newest stock rom but it is just so darn plain jane didn't keep it on long enough to test it. As for apps, I have basically the same apps on my phone that I had before root (except for specific root apps such as rom manager, titanium, etc).

Sadly they won't.. That is battery technology.. This world is pretty much stuck where its at and will probably stay there.. Its the one thing that is not progressing that much.. Even from the 50's
That said.. the thicker battery is the way to go.. Only you will know its thicker, and trust me.. ITS NOT THAT BAD! Believe it or not you get used to it.. If its for business, well then a thicker battery should not bother you at all, use it during the day and maybe at night switch back to the smaller one.. You know, for the dates and ****
The thicker battery will be a life savior.. All these battery tricks and tips help, but nothing is going to be mind blowing.. The fact is, this phone is extremely advanced and requires a lot of power.. I just except the fact that I need to be close to a power charger at most times..

I might go ahead and try Myn's new beta with 3.30 and see what happens. Looks as though I need to look deep into what is actually using my battery. I have always used K-9 for email and have heard it sucks up battery, but it only uses about 2% on mine and is the best email app I have ever found.
@fastfed......I'll have to ask my wife if I can go on a date sometime.

what helped me the most was wiping battery stats correctly (as per cyanogen wiki, but applies to all roms).
Charge to full, turn off, wipe battery stats. Turn back on, wait till everythings loaded, unplug. Use as normal until battery dies (do not charge at all until battery dies). Recharge fully in one go (meaning do not unplug while charging until full). Use and charge as normal.
This should be done whenever flashing new rom.

The biggest positive jump I have seen in regards to battery life was going from Cm6 to 3.29 ruu stock, then I ur3 to root.
I'm still sceptical that the 3.30 zip update gave any improvement to battery life as I have seen others report. In fact, I almost wonder if I somehow have less battery life now, but it could be in my head. It's almost impossible to approach this issue scientifically since I use this evo all day.

Try bakedsnack 1.8, its the best battery life I've seen on a rom w/o having to make all these stupid tweeks and disabling features on ur phone.

I'm gettin great battery life using vaelpak 2.3 with the stock htc kernel. I imagine most of the custom kernels around are based off of older kernels and while they may have higher "performance" ratings though I have hardly been able to tell a difference between kings 11 or baked speed and battery, I think the newer stock kernel is your best choice no set cpu to worry about, its just simple. I'm personally gettin about 14 hours with almost constant music playing to bluetooth headset, a bunch of browsing, and occasional use of google navigation which is a big battery eater. With just phone and text use after 21 hours I was at 52% yesterday.

ok so i have literally flashed every major rom / kernel and a comination of each. I have found that with minor tweaking most sense based roms get close to the same battery life. some people will argue that this or that rom is best but I would challenge others to truely preform a test on them and i bet they would be suprised.
k-9 is only a battery hog if you have it constantly polling for new emails if you have it set up to scan constantly then it will take a reasonable about of battery life but nothing more then most other email apps with the same settings.
have you tried as was lsited above and recalibrating your battery? I am assuming you are a pretty heavy user from the sound of things. How long where you getting pre root and how long are you now getting rooted? do you have titanium back up set up on a schedule? If so that can cause major battery drain as it sometimes keeps your phone awake.
All in all with the information you provided no one can actually tell you what is wrong. there are to many variabes and everything we say is a shot in the dark hoping to hit common problems.
my best recomendation configure your battery stats as listed above, if you havent tried use the HTC trick (chrage battery for 8 hours turn off phone charge for 1 hour turn on phone unplug it or 2 minutes then turn it off and charge for another hour.)
Anytime you wipe data you wipe your batary stats and it can drasitally impact your phones "battery life".

At this point I'm not so sure my battery or charging device on the phone isn't defective. But, only time will tell.
Currently I am running the newest, non-beta Myn TwoPointTwo and Netarchy 4.2 non-havs. I also ran this procedure (which fachadick already suggested):
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
I'm still on step 3. Will report back after a few days.
I had never heard of doing this when switching roms so hopefully it will help since I have swapped out a good amount lately.
Does anyone know where to get the newest HTC flashable kernel based on the new 3.30 release? All I have found is the rom package.

big mistake updating to 2.2

ever since I updated to 2.2, no matter what rom I'm using..performance has been so poor compared to 2.1. I wish I never updated. My battery runs out quick, temperature goes up to 100F even when idle and my phone hangs every time I turn on wifi. Hopefully I find out a solution soon, i've been flashing and uninstalling roms all day these past two days. I love the phone though don't get me wrong =\

That sounds quite odd.
Are you using an unmodified SBF, or are you using a release where the author/publisher has made a lot of changes? When having problems, it may be best to stick to one release and try to narrow down your problems, instead of trying many different releases and introducing new variables into the mix.
Are you overclocking your phone - perhaps it's causing the rise in temperature? Or are you running a lot of widgets? There may be some widgets that use the system too aggressively, causing too much strain/heat.

Hi! Did you do "wipe" before and after flashing?

That is very odd. I am on Froyo and performance has been phenomenal ever since the flash.
I agree with naenee, check the ROM you're flashing...

i flashed the UK 3.4.2-117 and right now using Pay's 2.1 rom. I remember that I did wipe data/cache before flashing and after flashing. IDK, im just not having problem's with this particular rom..it seems like it happens on all the other ones im trying. I get random freezes and especially when I toggle on wifi. I recently installed setVEL and will see if battery improves, this means i don't need milestone right? I'm also using setCPU.
I might try to flash 3.4.2_131-003 PL version. Will it cause any trouble and can I go back down to UK 3.4.2-117?

Seeing as it uses the same kernel, you should be able to do so...

I have been using the orange 2.2 for several days and no specific problem is noted.

well I reinstalled pays rom first and everything is working good. No more hang ups or freezes but I still can't get the battery to last as long.My phone is mostly idled, running on 2G, just one widget, and everything in settings turned down to the least minimal settings..im talking about battery saver, screen brightness all the way down..everything off! 6 hours in and im already on 70%. I can live with that but I'm using setVsel and I know it could do better. Anyone know another way I can make my battery last longer?

I'm running Pays latest rom based on the UK 3.4.2 and it runs great. I'm also using setvsel (as every defy user should) and optimized all my vsels ([email protected], [email protected], [email protected]) using stability test. I haven't had a 'normal' day of use yet, but with heavy use (installing apps, web browsing, flashing rom) I've gotten at least a full day (~15 hrs) out of a charge.
I recommend minimizing your vsels using setvsel, then judging your battery life. Check out the setvsel thread for more help.

And remember this is a smart phone, some people report getting 2 to 3 days of use out of it. That's basically idle time tho. These new smart phones are just that, and use much more battery than the Dumbphone.

Even if that's the case (and I dispute it, I use my phone a fair amount in the ~3 days the battery averages), it still doesn't explain why the OP's phone is dropping 30% in 6 hours while idling.

When I updated to froyo, my battery life went from about 15 hours of use to 21 hours between charges. So I'm thinking the op has an app doing the draining.

Unfortunately, this is a characteristic of Android.... Ridiculously inconsistent in the battery department.

Wife's phone is on official froyo, has been amazing since updated (a few weeks ago) but since yesterday some weird reason it's been super glitchy and freezing up. Not sure why...haven't changed anything to it and she's only downloaded an app or two (such as pandora) in the last couple days...I was playing around with it trying to figure out what was up...can't figure it out. I went into titanium backup to freeze some apps thinking maybe some blur crap was freezing it up but TB froze up so I can't even get in there. Also, same as OP, the battery has been heating up really quick lately, especially when on wifi.
Not sure what's up here...but I'm hoping nothing serious! Will keep you all updated on this...we'll see if there is a trend going on here.

check your cpu usage... if it's constantly arround 99%, you may experience the "usb-plug/unplug"-bug.
try enabling usb debug and restart your phone.

I would rather say it is a characteristic of people using android, to have widely different usage patterns, causing differences in how long a charge lasts for each.

Hi there. Have you tried to recalibrate the battery? There is an app on the marke called Battery Calibrator. From what I understand if you play with roms the battery can give you problems so it need to be calibrated again. I hope this can help.

For those interested... I'm having a problem, I don't know yet if it's a bug or a hardware defect.
My phones wastes A LOT of battery while it should be suspended.
I've tracked the problem to, apparently, Motorola's SIM driver. From what I've discovered so far, the SIM isn't accepting the suspend state and therefore the "suspend" process uses too much CPU time... all of this when the phone is, supposedly, saving battery.
As I can't get a motorola engineer involved, I can't say for sure if this is the true cause... but it's the closer I've got to a diagnostic, so far.
Your problem might or not be related to this, but if you're interested about what I've found or what my kernel log looks like so you can compare with your own problem... this is the thread at motorola's owner forum:

[Q] Most stable custom ROM avail

Hi all,
I know most of you guys use CM7 RC0 But I just want to know which is the most stable custom ROM which has all the features avail and no FCs or ANRs?
I almost tried all the ROMs including Stock Eclair, Froyo, CM7, MIUI, China Unicom etc. Currently using China Unicom 2.10,
My main concern is about battery coz no matter which ROM i use I get only a day of battery life :
So I'm looking for a Froyo/Gingerbread ROM which gives MAX battery life, supports HD video recording, fast and stable. Of course Ill stick on to CM7 once the official version gets released.

I am also looking for a rom with good batt usages n smoothness will wait untill any1 rreplies

for good battery life, please keep the 2G on, and switch to 3G only when needed. this is probably the best thing you can do for your battery life. also, make sure the baseband is correct for your usage. however, only you will be able to do this yourself. try a few until you hit a good one.
cheers!

Well.. Of course I always follow the tips to conserve the battery like setting to 2G, very few animations, setvsel to undervolt, not many widgets. But still I get around 1 to 1.5 days of backup.

I have been using CM7 beta 6 for a few weeks already and it has been pretty stable. Lasts around 3.5 days with moderate use. Heavy use( a lot of phone calls), around 1.5 - 2 days.
Just make sure that you select the correct baseband.

Yes, I install the correct baseband everytime I change the ROM, I'm suspecting my sim might be the culprit which is not letting the phone to go to DSM. Ill change it and see..
How stable and cool is Pays rom???

If you can get through a full day with the "micro laptop" we now refer to as a phone, you're in good shape! Plug it in every night and be happy.
If your particular usage patterns don't get you through a full day, or if you can't plug in every night, there are plenty of extended battery options available.
You guys need to understand that the manufacturers are forced to decide between battery life and size/packaging. Today's phones are designed to be practical for the average consumer who is able to plug in/recharge their phone every day. And fortunately, the aftermarket offers us the option of getting longer battery life in exchange for a larger package (ie 3500+ mAh batteries with covers)...

Some Help in choosing a new ROM. (a few questions)

Hey everyone, this is my first post in this great forum.
I am looking for some help in choosing a new ROM for my HTC desire, the main thing i want to see is the new Gingerbread OS 2.3 and the improvements it brings (battery life), but sadly it has not been officially released to the Desire platform.
EDIT :
Okay now Im on CM7, probably gonna try oxygen later, but till now CM7 suits all my needs and the battery seems good (20 to 26 hours heavy usage) but im running into a small problem.
at 9% the battery dies and phone turns off, battery and phone seem somehow out of sync so 9% means 2% or something, how can i fix this and make it turn off at 2% ?

If it's battery life you're interested in, Oxygen is pretty awesome, but it's AOSP so doesn't have any Sense stuff (widgets, messaging app, camera etc) - there's stuff on the market that provides equivalents/better versions though.
I've just flashed a sense ROM a couple of days ago after coming from Oxygen and I'm missing Oxygen so much that I'll be going back to it tonight It's very fast and stable.
But if you want to stay with Sense, this ROM is as close to stock Gingerbread (with Sense) as you'll get http://forum.xda-developers.com/showthread.php?t=1124810
People have been getting good battery life with that but I've not had too much luck getting great results. It's very smooth though
EDIT: CyanogenMod 7 I can't tell you too much about as I've only briefly flashed it. I remember it didn't feel as "clean" as oxygen but it had a huge amount of customisation potential (though saying that, the latest Oxygen build has almost as much, with the ThemeChooser). Also I don't think CM7's battery life is as good as Oxygen's.
What I'd do if I were you: Flash the CM7r2 HBOOT from http://alpharev.nl/ then flash Oxygen/CM7/SGBS depending on what you want to try first - all 3 work on that HBOOT so if you don't like one you can just flash another quite easily.
Make sure you know what you're doing flashing HBOOT though as there's a risk of bricking associated with it. So just read up first.

Thanks.
I decided to try CM7 7.0.3 for a while and i like it. Alot of customization and some neat features, but the downside is that i dont feel like the Battery consumption has changed at all, its still as i have had my 2.2 froyo stock i think.
I did a small measurment of battery consumtion please tell me if i should be getting these results:
First
-Phone with CM7 rom Charged at 96%
(turned on wifi for like 10minutes, did around 6 phone calls, 1hour looking around settings, animated wallpaper activated for an hour)
After exactly 6hours the battery went down to 76%
So in 6hours the battery decreased 20%
Is this a good result? Will I be getting better battery life in the Oxygen rom ? If so i will definitely switch to Oxygen.

Well that's not exactly bad. I'm currently on 42% after 20 hours 30 minutes with WiFi on syncing emails every hour, a bit of browsing, over an hour of gaming (trial xtreme), some texting, about 20 minutes of calls and some music playing too. Idle it probably uses less than 1% per hour. I'm on the latest oxygen.
I'm really happy with this battery life
I'd recommend downloading battery calibration from the market to get the most from your battery.

Redux is a good ASOP ROM with good battery life - its quite stripped down.
For a sense ROM - I like LeeDroid.

Or completely ruin it. Battery calibration is to be used only if your battery percentage is out of sync with real mV status, so your phone ends up dead at say, 10%. It is not to be used to decrease battery consumption, which is not going to happen. Ever.
To OP, it boils down to your preference. I couldn't care less for ota updates, but if you do, flash ruu, or maybe even rooted stock would work, I'm not sure about that though. As for battery consumption, you had 1 hour screen on, some calls and texts. I'd call that fair.

Yeah you're right. I meant battery monitor widget. It was late at night, forgive me
Battery monitor widget gives you a good idea of what your drain can be attributed to so is a very handy thing to have on your phone. Battery calibration (as the poster above mentioned) is to line up the amounts your phone reports with the true amounts and should only be used if you're getting strange shutdown occurrences etc. Sorry about that
Some people use juice defender too but I don't really like it tbh.

Yeah, those placebo apps are the best
Juice defender, setcpu, task killers, memory menagers etc share the same place in the Hall of sillyness.

Or completely ruin it. Battery calibration is to be used only if your battery percentage is out of sync with real mV status, so your phone ends up dead at say, 10%. It is not to be used to decrease battery consumption, which is not going to happen. Ever.
To OP, it boils down to your preference. I couldn't care less for ota updates, but if you do, flash ruu, or maybe even rooted stock would work, I'm not sure about that though. As for battery consumption, you had 1 hour screen on, some calls and texts. I'd call that fair.

To the OP (not erklat)
If you flash a carrier RUU you're all set for ota UPDATES.
If you de-branded the phone yourself, you can still get ota updates, just make sure your goldcard is installed prior to installing the update. If you update without a goldcard you will lose your data connection
If you have a rooted stoc, same as erklat's opinion, I think it should work but I have never tested this myself.

No i read this method and many users are reporting battery damage. I dont want to do this. My battery on regular use (calls, wifi, games,browsing) lasts 26 hours max and on idle it could last like 40 hours or more maybe.
Its just that the phone is turning off at 9% battery.
I used the Battery calibration app suggested before by cgmorris89 but then erklat said that it would ruin things.
What can i do to make my phone turn off at 2% ?

Oxygen every day!

Try MIUI.us!
Miui is using cyanogenmod kernel and base over which it gives great launcher and best default sms and phone apps.
Firewall and white/black list call blockers are included also.
If you can live with english locale, of course.

Thank you guys, yes i will try Oxygen and MIUI later on, but now im testing with CM7 and i have this battery percentage problem. If anyone has a solution to this, will be very much appreciated.
And another thing, should i update my Radio ? i have 4.08.00 something, is it safe to do so or might i brick my phone ?
