Battery running super hot

I know that everyone has problems with the battery but I've never seen anything like this. I used to barely be able to squeeze 8 hours out of it but it keeps getting worse. The battery is always really hot, running at around 40 degrees celsius and depletes itself pretty rapidly. I've been off the charger for 2 and a half hours and I'm already down to 48%. Has anyone else seen this or had it this bad? I've searched the forums here and at PPC Geeks but to no avail. I'm running Fresh ROM 0.3.x. I haven't had time to update but it's on the to-do list for today. Any help would be greatly appreciated.

And it's dead. 4 and a half hours. PoS.

I am too getting these results. I think it is fresh rom because im running it too.

Try Damage Control. Battery life is pretty good. Set profile in Dconfig to battery saver. Even overclocked battery is pretty good. No matter what though, if you're power using the phone (games,internet,etc) its usually only gonna last a few hours. Task managers help also.

I've got ATK killing apps every half hour and today I barely used the thing. I didn't get a call, not one text, and maybe only used the Engadget app a couple of times.

Mine was a little warm when I first got it (power using while playing!); I took it to Sprint techs and they investigated. Mine was normal due to high use, but there WAS a known issue with some bad batteries, and they were ready to jump in and replace mine if it had shown those symptoms.
Now rooted, running DC ROM on mixed battery savings/performance profile...perfect. No issues. At least 18 hrs per charge with fairly heavy phone use.

what were the "symptoms"? i would like to know...

Try clearing your battery stats. I had the same problem(crazy warm battery and really bad battery life)
I did it through the recovery(clockworkmod) go to advanced then wipe battery stats. theres other ways to do it too just search around here and you'll find them.

I installed the latest Fresh ROM last night and it seems to be working great now. We'll see as time goes on.

[Q] Crazy Power Consumption

Hey please don't tear my head off, Ive been looking through all the threads that I can, but haven't really found an answer.
So I got my g2 and left it stock for a couple of days and the battery did pretty good, meaning I didn't have to charge it during the day. I then rooted and flashed cm 6.1.1 stable and the battery was terrible it would drop about 1% every 5 min or worse if I was playing a game or using maps etc.
I tried switching to pershoot's cm_2632.28 012211 and it was just as bad. I then tried reverting to a back up of stock and it is still bad, I also tried RC4 and one of the nightlies, same problem. I tried wiping the battery stats with the instructions on cm's wiki, still terrible.
It is really frustrating to me and I have been looking around and it seems a lot of people are having trouble with battery life. I don't really want to buy another battery, and have tried removing anything on my phone that could use battery (widgets, apps, etc.) I also think it's odd that Cell Standby takes up the most battery.
So really what I want to know is does anyone have an idea of something for me to try? A mistake I might have made? Tip? Or am I just crazy in expecting my battery to last the day on stock?
Any help would be appreciated thanks

A lot of people who ran the cm rom seemed to have this problem I don't and I assume it only happened after cm and still occuring I think somethings wrong with cm's kernal idk but it seems like it shorts out the battery because I ran a wrong kernal on my stockrom and had terrible battery life.

The battery truly might be a dud... The fact that your Cell Standby consumes most of the power is probably normal because you said you stripped your phone of widgets, apps, etc.
My gf has a Wildfire and her first battery couldn't last more than a couple hours, and she's a fairly light user. She switched out the battery and now it's fine, goes for a couple days now..

I am running cm 6.1.1 oc to 1.2 I do not have this issue. Try a new battery maybe?

Which kernel are you using? And with what settings?

Kernel is toxygene #1, screen brightness auto, gps off, bluetooth off, Wifi only when I need it, "wcdma only" so I don't get any edge drop-offs, overclocked to 1.2ghz-368mhz screen on, 245mhz screen off. My battery will last 9-12 hours of normal use, that's a few calls, some txting, facebook, mp3s in the car on the drive home from work, and an hour or two of XDA. I unplug at for work at 10am, I let it die and charge from 0 every day..
Google sync every hour, weather widget sync 4 hours, facebook widget every hour. Those are all my widgets.

You should really upgrade to CM7 now. Pretty stable, and my battery life is SO MUCH BETTER. If I use my phone heavily I will lose about 30~40% during the ENTIRE DAY lol. So my battery with moderate usage will easily last 12 hours. Before I had the exact same battery life as yours.
Also, I'm using the UV kernel from pershoot.

I'm on Virtuous v0.9.0 and I routinely get 12-15 hours a day out of my phone. That's with brightness set full, WiFi running (and usually connected), Tweetdeck, gmail, gtalk, etc all running with constant updates, etc.
If I pull it off the charger at 7a, by 7p I'm typically still around 20%, depending on how much extra use I've done (sms, voice calls, etc)

Yes, the newer version of virtuous is great on battery life and doesn't even have to be oc. I just flashed back to cm today to get everything up to date (I'm ocd like that and have to have all my ROMs current) and I too am having the cell standby issue with 70% battery after 2 hrs and light use. Just flashed the newest pershoots and letting it fully charge before I clear batt stats... will report back.
Have setcpu set to lowest with screen off and oc 1.2-346mhz

synchronization
I am using Visionary 0.9.0 and I had lousy battery life too, and have now either turned off background synchronization or at least made it very infrequent for all my apps that use it (facebook, peep/twitter, HTC Sense, HTC Hub, News, Weather, etc. etc.)
This has made a very big difference!
The biggest difference of all came from turning off synch within the HTC Sense and HTC Hub apps. These were having trouble connecting to their servers, and were constantly tying up my 3G signal causing battery drain. This change alone has almost doubled my battery life.
I recommend you check what is using wifi/3G and how much before we assign blame to kernel or ROM.
Also, I can recommend GreenPower app which turns off connectivity automatically when it's not needed, greatly extending battery life. However after a long period of using this successfuly, I have turned it off as I started having trouble "waking" my 3G connection during the day. Hopefully future updates will help with that app.

I had the same problem with my first G2 and after complaining/convincing T-Mobile it was defective, they sent me a replacement and that problem never came up again.

Alright I feel stupid but I was charging my phone with my bluetooth charger (didn't even think about it) but now I'm using the stock charger and my battery is lasting way longer. Night and day difference. I don't exactly understand why this would make such a difference in technical terms but eitherway major facepalm.

[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

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] Instant battery drops

Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?

Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.

Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS

That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?

Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.

Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.

Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.

Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.

so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.

Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

These are my overnight stats when I was sleeping. It's usually worse when wifi is on.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.

Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.

figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.

FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml

Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.

Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?

[Q] Weird HTC Wildfire Battery Meter Issue

ROM : Cyanogenmod 7.1.0.1 Android 2.3.7 <<< Doubt this is important
Kernel: 2.6.35.14-nFinity [email protected] #1 <<< Might be important
S-ON
Okay so my Battery meter is definitely acting up. After charging the battery overnight it only charges to about 89%, maybe 91% if I'm lucky.
If I unplug and immediately reboot the device the battery meter says 98% or 97% at startup. Right now I have a reboot scheduler app that restarts my phone every morning at 4AM so that it's accurate-ish in the morning.
But that's not the only issue...
When I use my phone during the day, maybe making a call or two, on a 2G network to save battery, no Wifi or Bluetooth use and phone not overclocked, my battery drains incredibly fast. It goes down 15%-20% per hour! By about 3PM the phone says 15% left and then slowly drains down to 3% battery life. This is when it gets real weird... The battery level stays on 3% for about 6-8 hours, then finally goes to 2,1 and then dies. I got 3.5-4 hours on 3% with max overclock (768mhz on performance setting), maximum brightness, screen doesn't turn off, playing music while on HSDPA network, bluetooth on... So the battery doesn't seem to be the problem, only the battery reading that is displayed.
I tried going back to the default software that came with the phone, Android 2.1 with Sense and original kernel. The battery drain was a little slower but same effect, staying forever on 3%.
Can someone please explain to me why the phone does this? It's not a trainsmash, at least the phone isn't really draining as fast as it looks, but I effectively have no idea how much time the battery has left, which isn't ideal. It still lasts me the day and I charge it every night but I'd like to have this solved, it wasn't always like this. The phone is now 10 months old.
Any help at all will be greatly appreciated.

I sent in my Wildfire for repair. Got it back and it's not the chipset.
Its something to do with clockwork or Cyanogen.
The battery was fine until I re-flashed them.
Now it's back to the same ****ty battery life before I sent it.
Soon as I get home. I am going to flash a new rom. Possibly an older clockwork and flash a new radio.
Will post results.

If you notice the first thread, people who have never rooted/modded are also experiencing this. But, in either case, do post your results.

True, but in my case I know the problem to an extent.
I remember now that the battery starting acting up after updating to newest Clockwork recovery.
So I will flash that first. Run tests.
Flash Radio. Run tests.
Flash Rom (non-cyanogen). Run tests.
I shall do tests 1 day at a time maybe if tests prove a posotive results then I will do 2 on the same day.

Don't forget to re-calibrate the battery before your tests. It's a major cause of battery drain on Custom ROMs.

Ah, yes. Almost forgot :3
