I really don't understand my hero - Hero, G2 Touch Q&A, Help & Troubleshooting

Hi everyone, I really don't know where locate this "thing" is happening to my hero but it is definitely related to ROMs.
I recently post my battery problem in the battery's thread in this forum but seems like a battery calibration was not the solution.
I used to have Floyo on my hero and it worked perfect, also battery life was pretty good. Since I changed it to try another one, I can not have any 2.2 ROM in my hero cause battery drains almost 15-20%/hour with wifi off, sync off, screen minimum, 2G network, just the necessary to receive calls.
I've tried all 2.2 ROMs with different kernels, always wiping everything and none of them works property. I decided to install a 2.1 ROM and voila, more than 2 days of battery. Does anyone have any idea of the problem?
Other thing is driving me crazy is why I have to use toggle set (because of handset problem->always is on even when is not plugged) but only with VillainROM 12 I don't have this problem, I thought it was a hardware problem.
For all of this, my hero is understandable, any light to see what's going on? Thank you all

BEfore flashing a 2.2 ROM, wipe EVERYTHING, including battery stats. Let then the battery drain to 0, and charge the phone with the wall charger for 6-7 hours, then turn it on while it's still plugged and leave it like that for 1-2 hrs. Then unplug it and there will be no more drain.

Maybe this could also help you, when you set up your 2.2 rom for the first time,
have you ever disable google backup?
I have been told that drain battery like hell....

Thanks, I'll try next time doing it in this way and I'll see the results thought I think it won't change cause even if it's not fully charged I wipe battery stats also when i flash

Batteries die with time, so if you keep having a problem, you can consider investing $20 in a Mugen Power extended battery (1550 mAh) which doesn't need the back cover to be changed.
I greatly recommend it.

HOW TO: Solve Battery Life Issues

***NOTICE***
The ROM Manager version of CWM does NOT wipe battery stats properly, as with many other things. What you need is jt1134's version of CWM that is all happy and works and stuff.
You can find his happy CWM here. And here. And also here.
And here.
Big thanks to LegionTHEFecalExcretion for the heads up on that.
***END NOTICE***
NOTE: On current DL30 and EB01 ROMs, you will not see battery life like you did on DL09 with undervolted kernels. There are NO undervolted kernels as of yet, everything kernel wise with Froyo ROMs in very much stock. These steps will improve your battery life in comparison to when you flashed Froyo, but you are not going to see spectacular changes in battery life up to what you were getting with undervolted DL09, etc. It's just not possible until we get undervolted kernels and Froyo matures for our device, development wise.
Hi everyone, I've been seeing a lot of threads about bad battery life, whether switching to Kaoscinate, Vanilla, or DL30. Stop it! Just kidding. There is a simple process everyone should follow when switching between different enough ROMs, like AOSP, CM6 and TW Eclair and Froyo. This is how you retrain your battery.
1. Charge your battery to 100% (when it gets there, let it SIT there, your phone is NOT reporting correctly).
2. Reboot to Recovery and Advanced -> Wipe Battery Stats.
3. Reboot, and use your phone until it is VERY low (5-10%, you can let it die if you want).
4. Charge your phone back to 100%
5. (Optional) Power down, then power on phone. (Thanks goes to BrwnSuperman for this suggestion, give it a try!)
Your battery issues should be solved. This needs to be done every once in a while, especially when switching between different ROMs and OS versions.
User dalrym05 posted this alternate method for retraining the battery on page 4 as well, so I thought I would share it here in the OP. I'm posting this as a USE AT YOUR OWN RISK method, as I have not tested it, and am not quite sure what the *228 steps for it actually accomplish and have to do with retraining the OS battery reporting, so I'm leaving it quoted to dalrym05 for the time being.
dalrym05 said:
Here were my steps to better battery.
1.*228 option 1
2.*228 option 2
3. Run battery completely dead to 0%
4. Plug in and boot immediately into cwm
5. Wipe battery stats and dalvik cache
6. Reboot and let charge fully before unplugging
7. Completely discharge again and fully charge again.
After this you should notice a very nice increase in battery as I did. My battery life is back up to par with eclair.

NOTE: I did edit his post to make it a little more clear. I'm slightly anal retentive that way.
HybridByNature had an excellent suggestion on page 4. If people have good tips and tricks for maintaining good battery life, and they are easily reproducible, then I will gladly add them to the OP here. What works for you?
HybridByNature said:
This might also be a good place to add tips & tricks to extending battery life.
IE
-Close programs that you aren't using.
-Don't leave your camera or navigation running in the background.
-Turn off WiFi & GPS etc when you aren't using them.
-Don't run your screen at full brightness if you can help it.
-Figure out what uses more battery life than other things:
Pandora, internet browsing, downloading, camera/camcorder, Angry Birds etc.
If you are rooted, try and narrow it down to the best kernel/theme for your situation. I've found that I have better battery with a non-voodoo kernel but the performance increase is worth it so that's a trade-off that I make.
Let's hear from our readers: What is working for you?

Would not surprise me if this is all it is. I have turned my phone off at 5% for an hour and turned it back on without charging and then it showed 45%. I know when batteries are low letting them sit a little bit can help, but not that much.
It is just being reported inaccurately by the OS.

Yes, but not as a thread, it gets posted in everyone else's "Why does my battery life suck ass" threads, so I made this so maybe people would see it and try it before posting another useless question thread in Development.
Definitely works though. Did it yesterday. Good post. It has been posted in other threads ... but I think we all know people don't read through everything very often.

I have the battery charger and 3 batteries, I always run my battery low and leave it in the charger for a day.
I did this last night and it didn't work too well for me.
Also, when I go to wipe battery stats in the recovery, it doesn't tell me if it wiped or not, just goes back to the advanced menu.
And also, should I be concerned that when I cold boot into the recovery, it doesn't appear to be CWM? It says Android recovery...I know I have CWM recovery installed.

Wow same here..I just took mine off the charger bout 10 minutes ago and it's at 95% now. I guess I'm gonna let the battery run completely dead and charge it and see what happens.
I did something similar. I charged to 100% while it was on, removed from charger then powered off. When phone was off I plugged charger back in and waited til it was at 100% then unplugged again and powered on. Waited until phone was completely on then unplugged again and connected to charger. Waited til it was at 100% and while still plugged in at 100% booted into recovery and wiped battery stats. Then rebooted phone into OS and unplugged. I had tried this previously with DL09 and it helped a little. Last night I wanted to see how my battery would drain after doing this. With WiFi on and I got about 10 emails during the night, from 8:30pm to 6:00am I lost only 13%!!! Previously I would have lost from 35 to 40%. ymmv

This is a proven technique, and it takes patience. Seeing the battery drop from 100% down to 95 or 96% after unplugging is normal behavior. I've done this already. Left my phone unplugged overnight and lost 1% battery. If you're too impatient to take the time to do this, that's your loss. You'll see the battery life "improve" over the course of a few days as the reporting gets more and more accurate.
Sent from my Fascinate using the XDA app
I agree with supplysidejesus. This is a standard practice and should be done with each major rom or kernel install. This leak hasn't been put long enough for most of us to know what our expected battery life will be yet. Give it a few days for your phones to adjust.

[Q] Fishy battery life

Hello all,
I bought the Atrix around 6 months ago and I have always had the same problem I'm about to describe. First I should mention that I used to have a stock rom and stock radio (77.15) until a couple of weeks ago when I flashed Cyanogenmod and radio 77.30p, yet the problem is present in both configurations.
My problem is as follows: my battery life is mediocre. Without using the phone very heavly, I get around 7-8 hours until it shuts off. Since day one I've tried many different fixes to see if the battery improved without success. Now here's the fishy part: for whatever reason, every time I make a full wipe (when I was using stock I did it from the "reset to factory defaults" option, now I do a full wipe on recovery) the battery lasts an insanely amount of time, something like 24 hours or more.
Here's how it usually works for me: I do the wipe, I boot my phone and configure my accounts, the phone syncs and installs the apps I usually use. Like I said, that day the battery will last forever, last time I've tried this I reached around 31 hours before I plugged the phone back on, and it was around 17% still. Now, the next day, without installing any new app or using the phone for nothing different, I go right back to the mediocre battery life. For example, it just went from full charge to 88% for just 10 minutes of browsing the net on wifi, not even using 3G.
Like I said, this happened with stock ROM and now with Cyanogenmod regardless of the radio I'm using. I have calibrated the battery a million times, I've tried with Watchdog which didn't show nothing, the same with Better Battery Stats. I really need some suggestions on what to try because it irritates me that the battery is dropping so much with such a light use.
Thanks!
I'm getting also quite short battery life with CM7. I'm wondering what the reason could be. It gets down with 15% for just 5 hours without any phone calls. I have just whatsapp and email checking every hour. No other resource hungry applications. With the stock ROM and the same usage I'm getting around three days ~ 72 hours.
Well in my case it's the same but with both stock and others roms. I suspect it's a software problem because I get normal battery life when I do a full wipe.
Did you try to revert back to unlocked bootloader.
What I found strange is that somehow the indicator doesn't show the ratio mAhercentage. On 85% battery the calibration battery shows charge 4030 mAh which is not 15% less than the full charge of 4200 mAh.
Well actually this problem has existed from before I unlocked the bootloader so I don't think that's the problem. And in my case the mah percentage is correct. It's like if somethings draining the battery that I can't find. Maybe is a problem with my carrier?
If the coverage is poor where you live then it is possible to get lower battery life than expected. Another solution is to revisit the application you use, try also to do a full wipe including formatting the internal memory card.
Go through this process: http://forum.xda-developers.com/showthread.php?t=1198333
You'll be good to go after that. Check also BetterBatteryStats here in xda, will show you what processes eat the battery.
Thanks but I've tried that when using the stock rom and it didn't help me. I think that solution is for a different problem as it's mainly to display the correct mah percentage, which is not exactly my problem. Also, CM7 already includes juggernaut fix.

Have you tried a different radio?
Yeah, like I said I had 77.15 at first and now I'm using 77.30
There's more radio's, check in General.
Ok, I flashed 77.36p and there was an improvement, I've unplugged the phone around 13 hours ago and I'm at 25%. Would you consider a good battery life for a light use? It's getting better but I saw many people crossing the 24 hour mark on their phones. Are there any other radio to try other than 77.15, .30 and .36 that would be worth it?
Do a full wipe in Fastboot & install Nottach's DarkSide and leave it with the stock kernel. I'm at 77% with 1hr 40 minutes screen time & 17,5 hrs standby..
P. S. I'm using the N_01.100.00R radio. Am in Germany, though on an at&t phone. Best radio so far.
Anywhere from 13-20 hours is fine but keep in mind it's all dependent on what's on your phone. If u have a bunch of apps pulling data from the internet or something ....I mean its all dependent on your phone setup.

[Q] Battery Drain Problem

Hello all,
I purchased a Galaxy S2 at the end of July, I live in the US, so it was from Amazon. The phone has been phenomenal, an amazing piece of technology.
I rooted the phone and flashed Lite'ning Rom 6.1 XXKH3. Still worked great, with no problems at all.
However, starting about a week ago, I am getting an extremely fast battery drain. Since then, I have spent hours looking at threads trying to figure out what was going on. I updated the rom to UltraToxic Rom v8.0 XWKK5, still no change.
I used Titanium Backup to freeze many widgets and app processes, still no change. I am currently using better battery stats to monitor wake locks, however after managing the wake locks, still no change.
I then bought a replacement battery thinking that the battery may have been bad, sadly, there was no change.
I have been trying to find a solution to this and had tried many other suggestions in other threads to no avail. As of now I have come to the conclusion that the device might have some type of malfunction that is causing this.
Am I going crazy or am I missing something obvious? Any help would be greatly appreciated.
Thanks
I have also re-calibrated the battery, still no positive changes.
Seeing the battery graph, you have your screen on a lot of time. Screen sucks battery a lot, so there might be one of the causes of battery draing.
Also you seem to have all day enabled 3G/WiFi, that also sucks some battery with it.
You can try JuiceDefender and see if it can help you extend a little your battery.
change kernel
Try flashing hardcore's "SpeedMod Kernel" and you will never complain about your battery life.....
After flashing this kernel my worse battery life was 1day and 12h with 3.5h screen on and wifi 85% ON.

Lol.... It's obvious he has some kind of battery problem, he is not using the phone much, and galaxy S 2 should have at least 5-6 hours screen on time and the phone lasted 3 hours.
Sent from my GT-I9000 using xda premium
Since I had all data on the phone backed up, I did a factory reset. I also flashed the UltraToxic Rom v8.0 XWKK5 as well as the suggested SpeedMod Kernel. When the battery was at 100%, I calibrated the battery. I tried to leave the phone idle as much as possible, I did use the internet for about 10 minutes to check e-mail, news, etc. So now the phone is essentially "empty" in terms of apps downloaded, I got rid of all widgets on all home screens.
There was still no positive change, I do really like the SpeedMod Kernel though, I do notice faster responsiveness from the phone.
I am beginning to think that the problem may be the hardware and not the software or battery.
I've got similar problems here. I am suspecting a hardware problem (I damn well hope it isn't coz i got mine from hong kong) because my phone never goes into deep sleep mode for more than 50% while the screen is off. I've tried at least half a dozen different kernels and roms and nothing helps, this is even in airplane mode i.e. with pretty much everything turned off. I've tested wakelocks and dont get anything more than a couple of seconds. I had my battery charged to full at 6:30am this morning, went to work and got home and it was dead after just under 12 hours with being idle 75% of the time. This is worrying as most people's battery lasts at least a whole day.
So I know it can't be the kernel, I know it cant be wakelocks, I know it cant be wifi or 3g data or anything of that nature so the only thing it comes down to now is hardware...
Funnily enough I've had exactly the same issue since about a week ago. Even when I take it off charge it's almost immediately down to around 80%. It's lasting around 4-5 hours, even when I'm not using the phone much, plus it gets really hot.
A couple of times Social Hub has appeared high up on the list of battery draining apps, although I don't use it. It doesn't always show up though. I switched to the CF-Root kernel and started using GO Launcher EX recently and wondered if that (or one of it's addon widgets) could be the cause.
It's really bugging me now!
SOLVED!
After days and days of trying to fix the issue of the phone not sleeping (and therefore draining excess battery whilst idling) I have finally fixed it!!!!!
First i noticed that along with the sleep problems, I was getting the problems with car mode popping up randomly, the phone going into mtp connection mode, and thinking its charging when it was unplugged. After looking into these issues (and i thought it was a longshot) I decided to do what people were saying and CLEAN THE MICRO USB PORT.
Now you're probably thinking I am a crazy man, but now im just crazy happy that I don't have to send my phone back to Hong Kong!
Instructions:
1. Get a clean, dry, soft-bristled toothbrush.
2. Take any case you have off the phone.
3. Gently insert the bristles into the port and "flick" it out softly.
4. Repeat this about 10-15 times
No matter what ROM, what kernel, what modem i tried flashing, my phone was always sitting on no more than 50% deep sleep mode when idle and had no wakelocks or "rogue apps".
I am now getting 90% - 98% DEEP SLEEP MODE!
I obviously can't guarantee that it will work for everyone, heck how it solved the issue is a mystery to me, one which probably an electronically-minded/computer systems person could answer. What I can say though is I searched high and low online for about a week. I tried different kernels, I tried different ROMs, I tried "re-calibrating" the battery, I used BBS to check for partial wakelocks. If you too have tried all this and have had no success please PLEASE try this and see if you have success!!
Thanks for reading!
....
Or if you didnt...
TL;DR: If you're having battery drain problems clean the micro USB port with a soft toothbrush.
The phone never sleeps when charging, the CPU idles at 200 MHz, whatever was in your USB port was probably making contact with the pins that tells the phone it is connected to a charger when it actually is not, so it was idling at 200 MHz and was not receiving power, that's the only explanation I could fathom
Do two things:
Install CPU spy and show us what the deep sleep percentages are,
and try disabling wifi. Also, what is the router?
I have a battery drain issue; but its kind of screwey as i will reboot my phone and lose about 20% of the phones charge. If i turn it off and leave it off for an hour the charge comes back. Its random as well; only happens once a week. I have had this problem on different roms. You might have a similar problem to me. Possible the hardware that detects battery state is knackered.

ICS Passion v11 battery life is horrible for me

I was running bionix from before I decided to switch. I flashed back to stock via Odin and flashed to ICS Passion v11. It's an excellent ROM but my battery life is abysmal. Just texting for 5 mins drains it about 8%. I have to charge my phone 3x a day in order to keep it alive. Really like this rom so does anyone have suggestions on what to tweak or disable to fix this?

Yeah same for me.. I had to buy the Samsung Galaxy Epic 4g 1800mAh battery.. It solved my problem. You can get one on amazon for like 20 bucks. It's totally worth it. For some reason the 1500mAh battery gets random drains on this ROM
It's not just this ROM. I have noticed it on all the ICS Roms. Some of the apps are not configured properly for ICS yet, thus the battery drain. When you re-install your apps using Titanium Backup try not restoring data.
Bump for possible solutions. The new battery is a good idea. I hear so many people claiming battery life is superb and mine is far from it. I never restored apps with titanium backup either. Everything was clean slate
When I was running ics, i had a few times where my phone would not deep sleep. I just reinstalled and it seemed to correct it.

When I first installed Passion V11 my first full charge only got me about 8 hours of use. I installed BetterbatteryStats and CPU Spy, and Battery Monitor Widget. I looked at the logs and saw that Beautiful Widgets was causing alarms and kernel wakelocks almost non-stop. After identifying the problem app and uninstalling it, my phone still has 70% battery with 24 hours of use.
You guys just need an 1800 mAH battery. The thing can last me a day and a half with no charge (assuming I put it in airplane mode at night). You can find it for $10-20 on Amazon or eBay.
To get best battery life all you need to do is "Charge Cycles"
For ICS Passion v8,
Charge Cycle means completely charging your phone too 100%, reboot and LET IT DRAIN UPTO 0%
Now charge it to 100% again without interuption and then reboot.
This is one/first charge cycle. Also get unused toggles off and remove unused widgets.
I would add that you need to go into Clockwork Mod manager by rebooting your phone, selecting advanced, wipe battery stats, repeat after drain to 0 and recharge to 100%

Best way to get the most out of your battery, hands down (although I never let it fully discharge. Got pegged once on another phone and it never held a charge again. My own superstitiion though b/c it was an entirely different manufacturer).
Also get unused toggles off and remove unused widgets.

[Q] Very fast battery draining!

Hello! I bought this phone last month. Since I got it, I've never experienced any problem with it. For four days, I noticed that the battery drains very quickly, without any logical explanation for this. The data connection is turned off, Wi-Fi is turned off. Last evening, I charge it to 100%. This morning,I found it turned off, with 0% battery. What solutions do you have to solve this problem? Have you encountered this problem?

- I ask this because I had a phone that would actually consume more power than a USB port could put out. when turning off the laptop, it actually allowed a back drain for some reason, and the next morning the device was dead. (Not this phone)
Also, what applications are running? Any?
Finally, you can try to retrain your battery... Wiping stats does not work, ever. So despite what anyone tells you, don't do it. You're just wasting time. SOURCE
So, how do you retrain your battery? Let it die completely. Then plug it in to charge. Don't use it while it's charging if you can help it. DO NOT remove it from the charger until it's at 100%. Once this is done, use it til it dies on it's own. Then yet again, charge it fully and then go back to your normal use.
In some cases, these batteries can go bad, for various reasons. A quick test, but is not always trustworthy is to spin your battery on either side. If it makes more than 2 full rotations, it's swelling and going out. Replace it.
The best alternative is to take it to a battery shop, and let them put it on a Cadex machine. (Pronounced Kay-Dex) ... This machine will charge and discharge the battery several times over a few hours and truly test the current life -vs- the life it should be. Anything rated less than 80% remaining life should be replaced.

I charge it only from power outlet, with stock charger.
Trib wrote 5 paragraphs on info you need to provide and you come back with a small sentence? Pretty much if you use your phone a good amount it will only last you a day per charge. Unless you give us an explanation on how fast it is draining it's impossible to even start helping

6 hours 40 minutes from 100% to 10%, and the phone in stand by! Cell standby - 45%, Phone idle - 48%, Screen - 7%
And all this after a hard reset and retrain battery! The battery is almost new (aprox 1 month)!
I want it to make a screen shot of battery drain, but I have no clue how to do that on LG L9...

I hard reset it once again. Now is on charging. After that, I will provide you a screenshot with battery stats. Thank you for your help! I try to borrow an othe battery from an other LG L9 phone to see if is the battery or the phone! I hope to find someone with that kind of phone.

I attached a screenshot. Yesterday I changed the battery. Same problem! I take it this screenshot this morning, after I fully charged the phone ... Same problem, a new battery.
Can you please tell us what applications you have running in the background?
Also deactivate google now.(or the google services in google maps). download and install GSam Battery Monitor and after a cycle tell us what applications are eating your battery the most. It's clear that you either use yout phone(screen on time) allot or there is/are some applications that prevent your phone from going to sleep.
I use battery widget reborn and it shows me wneh the phone woke up,when the phone had the screen on,wi-fi on,gps on. Try it as well.
I also had battery issues when on JB. I downgraded back to ics. It's much more reliable when it comes to battery life. And the performance is about the same.
I don't have any app installed. After i replace the battery, i made a hard reset and I did not installed any app. I will install cpuspy and betterbatterystats for more results. I will back tomorrow. Until than, maybe you can provide me more advices. It can be from a damage sim card?

I guess your signal quality isn't good enough because cell standby is eating up more than 40% of battery. Cell standby in my phone is only around 5%..

I removed the sim card, but in flight mode is the same problem... The last solution is to change the rom with a custom one. Any recomandation?
It's not that. Not the signal. It's the firmware. JB has these problems. In ICS Display is the major consumer followed by Phone Idle and Cell Standby.
I also had these problems in JB and reverted back to ICS .
I would advise you to install CM 10.1 on the phone. The battery life is better than stock. I get around 12-16 hours normally. The latest RC4 has fixed almost all the bugs present in older CM 10.1 variations. Give it a try.
I will root the phone and I will give a try with CM 10.1 or I revert to 4.0.4. If all this will be for nothing, I will sell the phone!

On ICS you will get great battery life Telling from my experience as i have reverted back to ICS after trying JB and CM 10.1( both have very poor battery life ) . So instead of wasting time just flash ICS and forget about battery issue :good:
Where can I find a tutorial to revert to ICS?
Same question. Can some one please give a step by step guide on how to revert to ics for l9

Use the offline flash..
I also reverted to ICS and the battery drain keeps like a countdown
I have the p769, and I offline flashed up to V20D (and rooted). Removed some tmobile bloat, and I have pretty decent battery life. I guess I'm lucky.
