[Q] Battery Drain - Yet another whining thread - CM7.2 - HTC Wildfire S

Hello all together
I'm browsing xda for a little more than a year now. You guys helped me a lot!
First I want to apology my english, I hope you understand what I want to say
Not a long time ago the battery of my WFS lasted up to 3 days (incredible if I think of it now).
That was with a self rooted stock rom and some changes (bravia, turboboost script, oc-kernel, etc.).
Out of nowhere I had problems with my calendar.sync.provider. Processes htc.bg and htc.bgp used the most of my battery (found out with Battery Mix).
I could watch the percent falling... Battery was getting very hot.
After i killed calendar.provider and calendar itself those bg-processes disappeared and all went back to normal.
Installed m1nd's rom, tried a lot of different settings, used calengoo instead of normal calendar (uninstalled the other)...
But battery life was never the same since then.
We also had a really rough winter and I was outside a lot. my battery began to drain faster. First I began to install apps like "auto wifi toggle" to stop that battery drain, after all I just bought a new battery this spring - 1500mAh.
But other than i expected - battery life did not increase. So I decided to install CM7.2 (wanted to do it anyway - great work btw!).
And guess what, nothing changed...
You will find some screenshots at the end... (did barely use the phone this 4 hours)
So what can I do? I'm desperate. The battery does not hold the whole day...
Please give me some tipps (if you have others than the general battery saving thread) or at least cheer me up
tl;dr: Phone works for 10h (mail,text, no phones, no games) - Changing battery & ROM does not fix battery drain...
Thank you in advance!

it happens to me too unfortunately, i charge it everyday or every 2 days
when i play a small mini game for a few minutes, battery drains like over 10% in a few minutes.

Have you tried calibrating the battery?

Hey scilax can you please tell me how to. Calibrate the battery.
Me too get a smaller backup when 3g is used for some 3 to 4 hours.
Please tell about that calibrating

Thing is, I charge my phone everyday. And I've been using CM7 or CM9, battery life never lasts more than a day. If it's only lasting 4-10 hours. Check your sync settings. Keep it only on 2G networks if using data. Get a battery saving application, in my opinion, it sounds like your using a lot of mobile data/wifi.

Short battery life!

Hello people, after having used my Touch pro 2's GPS function extensively one day on battery, I have realized that the battery's life has shortened by huge amounts of time. It lasts for less than 24 hours now, so I was wondering if I needed a new battery or is there something I can do to restore it back to the previous state. Thanks!
I don't think using the GPS should ruin your battery, just doesn't make sense! Are you sure you shut off the GPS after using it? Are you running any other programmes in the background? Did you flash a new ROM?
My battery started going down twice as fast after swapping to the new "official" Sense 2.5 ROM.
you can try a couple of things that may extend your battery life. try first turning off the auto speakerphone when the phone is face down. i just did this and i can tell a marked difference in just a couple of days. also search battery life reg edits. theres a ton out there here and on ppcgeeks that will definetly help. in general i noticed that when I use GPS the battery drain is pretty high. hope that helps

Using the GPS all day will def drain your battery much faster, especially if you're using aGPS and/or an app that also downloads data to compliment the location info (like google maps). The GPS radio isn't 2-way like the phone or 3G or wifi, but it's still a radio and will give a noticible hit on your batt life when used even moderately, let alone all day.
If you're going to be using GPS a lot, you might want to try different radio roms to see if any of them make a difference in the batt life for you, but I don't know that will make as much of a difference as it does for the phone reception, etc. I would also suggest evaluating various GPS apps, with an eye on relative battery drain
Well guys, thanks for the answers, but that still doesn't solve my problem because I don't use the GPS function often at all, but the battery still drains quickly. Also, there are no programs running in the background. There is however a data connection that is always on and the mail checks for mail every hour. But the thing is I don't want to change any settings to enhance battery life, If it worked fine with the same settings before, why wont it do the same now? Do I need a new battery? Thanks!

Ahhh sorry, I misunderstood, I thought you were just saying it drains faster while you use the GPS like that, not since you used it...I get it now.
That one day of heavy use shouldn't have killed your battery, take a look at THIS thread, others with the same issue/question have posted different things that have worked for them...you might want to give the steps in post #31 a try before thinking about buying a new batt.

You can install " battclock " and you can continuously see what the battery drain actually is during different functions.

Yes, great recommendation! (why didn't I think of that? lol)
And with battclock you can now see your CPU usage in real-time, which is probably one of the best coincidental indicators of battery drain (much more so than memory load, in my opinion)
Hi Dimitri,
I experienced the same problem where my battery life suddenly "shifted" from 48 hours to 12 hours on regular use..
I thought the problem was the battery and I replaced it, this did not help at all..
The only cause of this problem that I can think was loading the official HTC UK 6.5 ROM (1.86.401.0)..

This is exactly what I am experiencing. (This together with not being able to connect the device to PC)
Installed several 6.5 ROMs and suddenly the battery lasts only half a night.
My question is: When the battery is full, when you turn the device off (completely off, not in standby mode!) does the battery drain then?
As far as I see, the battery has only 50% left after a night rest while it is off. So, the only way to keep the battery full is to remove it from the device.
What are your experiences with this?

If you are truely turning it completely off, the battery should NOT drain at all. Have you tried a new battery? I bought a pair of batteries and an external charger on flEabay for like $12. The batteries are good as originals as far as I can tell.

Yes, I have two batteries, even an external charger.
Even when a battery is charged with the external charger, then put in the phone it drains the battery
hey guys can anyone link any of the forum topics to tweak battery life? the only things I have done is the general setting on the phone and the power management options with advance config are there more options and tweaks available?
thanks for all help!

Bright light...I'm also having BOTH of those problems...stock ATT rom. Within the past week my battery life has dropped exponentially, and when I went to sync last night, had not done so in a week or so, I get nothing...none of my PC's will recognize the phone as even being plugged in, let alone sync. I'm thinking maybe an ATT botched update?

So it seems I'm not alone.
Mine is a universal one, no brand whatsoever. I will try to reflash the original (6.1) stock ROM, including radio.
Have you flashed yours already?
@Bright.light @VirtualHomer:
I have the crap battery + no activesync issue.
I'm on the Josh's Black 1.7 ROM. I tried hard reseting, reflashing, going back to the stock ROM, but no improvement.
I have heard that removing the battery overnight is a possible fix for the USB issue (maybe for both?), but I haven't tried yet, will try tonight.
If anyone out there has any potential soultions here... would be great. Right now, I only get 1/2 a day (~6 hours) out of the battery & no hotsync at all (other than BT).
One thing I am pretty sure of: The bad battery life and the activesync issue came up around the same time. Wierd.
Cheers

You are right in assuming that battery life and connectivity issues came at the same time.
I was assuming this was because of a (bad?) flash, or maybe a bad ROM which changed something in a position that should not be changed and which is not restored by flashing another ROM.
A night without battery won't help, I think, because my device has been numerous times without any power and without any battery. However, I will try it again.
Could this be a faulty device? Or a design error?
@Bright.Light
I confirm that a night without the battery solved nothing. I have had my phone on for 5 hours now, taken 5 calls, none of them too long, checked email every 10 minutes (automagically) and I am down to 27% battery.
Also, I confirm that a replacement battery solves nothing, as I have also tried this.
I am planning on returning my device to an ATT store next week for a replacement... We'll see how it goes.
Cheers,
Matt
I'm in the same boat with mine. About two weeks ago the battery just started draining fast. Fast enough that it wouldn't make it to 4-5 hours without being charged. You could watch the battery meter drain. And what was weird was that there was no ROM change or anything that started this. Came out of the blue. Calling Spring tomorrow and getting a replacement is the best solution I can think of.

Kernel Advice

I have poor battery life on my desire, it barely lasts 7 hours. I have tried wiping battery stats etc, and have the screen brightness at 50%. I have read that some kernels can greatly improve battery life, is this true? If so, which would you recommend, and do I just flash it like I would a rom? I am using the latest miui.
Cheers,
Steve

They can but finding the underlying app causing the phone not to sleep would be what I'd be looking at. Remove all installed apps and add them 1 at a time and see how the battery goes

Yeah i've tried this, there's nothing draining the battery.
Not at all
Such battery drainage can only be induced by either heavy usage, or phone not being able to go to sleep.
The differences between kernels in custom roms are merely a shades since all of them are pretty much battery efficient. You won't miraculously jump from battery life of 7 hours to 30 hours. Concentrate on your apps or even better, third party Widgets.

Probably a hardware fault then - the OS on it's own with no apps installed shouldn't drain a battery that quickly. Did you also turn off the sync options to test that theory?
Personally sounds like a knackered battery/phone
If it isn't apps/widgets (they are the culprit for heavy usage) then it would prob be a faulty battery. I did a little test last month to see how much battery I could lose in 24 hours. I lost 8%. I guess it could be a baseline to start off with.

[Q] Investigating a battery drain issue

Hello all,
A few months ago I became a proud owner of a Moto Defy, a great rugged phone that has been working great for me until just last week. For some reason the battery life was cut drastically! So bad that while the screen was off and not touched at all, the battery percentage would go from 100% to 40% in four hours.
what was even worse was when I would connect the charger, the phone would charge completely in less that 1 hour! I didn't seem to matter if I was browsing the web, playing music over the loud speaker, or just leaving it alone, the battery seemed to fall the same.
I began to research online for some answers since I couldn't believe that the battery would just go bad just like that! first I installed a custom recovery that had the option of wiping the battery stats, but that didn't work. then I stumbled across this thread on a battery bug in the android os 2.3.
http://forum.xda-developers.com/showthread.php?t=1039696
Even though the os on this defy is 2.2.1 I thought I was on to something. they talked about an app called watchdog. I also found an app called Battery monitor widget, which allowed me to see the battery usage in milli-amps.
I got concerned when during the day, I noticed a spike in the battery usage that was crazy! the app showed where the usage went from 99ma to 2399ma drain and I lost 8% of the battery in that one minuet! Keep in mind that the battery is only rated at 1500mAh to begin with. With that being said, I was thinking I have a short in the phone! The spike happened again later on that brought my phone to it's knees!
while reading further into the thread, I installed watch dog lite. Immediately after the installation finished, I started getting flagged for an app using over 60% of the cpu while the screen was off! Fancy widget 1.3, I had liked this app so much on my old Moto cliq, I imported it over to my defy.
Maybe I have found the culprit, I donno. This is just my experience so far, if anyone can add to this, please do. I will continue to monitor the phone and the activity of the apps. I am still shocked about the battery drain spikes that I saw! I am still, to my knolage, running the stock rom that came with the defy, now with the addition of Clockwork MOD recovery installed.
i have issues too, in the last week my battery dies in 13-14 hours with normal use. before that, it lasted 24-25 hours with heavy use. i also have sudden pattery percentage drops (which is probably the same as yours, that 8% in one minute). i already tried reflashing sbf/cm7, calibrated battery with cwm and app, nothing seems to work. now i disabled boot oc and use setvsel, and installed battery monitor widget and watchdog lite, maybe those will help :S
sent from my cm7 defy...
Since I installed rc1.5 my battery last for a fairly long time. It droped from 100% to 26% in 23 hours with medium use (data connection always active, when I used it heavily I turned on 3g, I used wifi and I was on a sunny place so the screen was bright)
Sent from my MB525 using xda premium
many have reported battery drain on rc1.5, seems its not present in every case. just installed 110909 nightly, so cant really report on that yet, but ill do as soon as i can.
Im on CM& RC 1.5, my battery last me a long time (more than 30 hours) using a lot of wifi + edge data, and lots of calls and sms, so i guess i dont have the battery drain bug

[Q] Battery drain

Hi, I've got my S4 mini week ago and I was really satisfied with battery life, but suddenly yesterday my battery went crazy and right now, I get over 10% battery drain per hour, with just simple use. I didn't perform root or anything else with my phone. Please does anyone know where should be the problem? I don't wanna go to service with my phone in first week that I have it.
I've attached picture of my battery use.
Thank you for your answers..
Judging by the screenshot, the battery drain seems to be quite ok - you have made some phone calls, the screen was on for longer time as it seems.
Try to test the battery drain without using the phone.
To get more detailed information about battery usage, you can try Better Battery Stats (here on XDA http://forum.xda-developers.com/showthread.php?t=1179809 or in Play store) or Wakelock Detector (in Play store) apps.

I have the same problem. One time i killed about 20 apps and my stats looks like below
but when i restarted phone baterry problem come back. Now i don't know what i killed, but i try to find it.
PS
I have 9192 phone. (3G, wifi, gps are disable)
Get an app which offers some better statistics. I would recommend BetterBatteryStats, but since it costs two bucks you can try your luck with WakeLock Detector first (sorry, not allowed to post links). What you want to look into first is, if your phone is going into deepsleep mode when you are not using it. Wakelocks wake your phone from deepsleep and this costs battery life. Install one of the above apps (if it is BBS activate the WatchDog from Settings), reboot your phone and put it away for an hour or do this over night. Then check if there apps which keep your phone awake. Good luck.
P.S.: It seems there is a bug in Android 4+ which causes battery drain on some devices, including Samsung devices. It occurs suddenly and can be stopped by a reboot. Google: android issue 22878
The ticket is from 2011 but was recently marked as obsolete, whatever that means.
cheers

CleanRom 5 battery

Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
