Potential fix for Battery Drain - T-Mobile LG G2x

First and foremost, I completely understand the battery reporting is inaccurate.
I, like most of the G2x users, have occasionally experienced excellent battery life and at other times barely lasted 5 hours. We all know this has to do with the LG battery drivers. I think I may have found a potential stop-gap fix though.
Another preface:I'm running CM7 nightlies.
Now, using SET CPU you can set a screen off profile that will underclock the cpu to be more efficient and save battery life, anyone worth their salt knows that. The other aspect of this that I have been doing is underclocking the CPU during normal usage. With min set at 312 and max at 760, I've gone 4 hrs and 13 minutes with 96% left. Even underclocked, this phone performs. The only issue I've noticed is a little bit of buggery with the lockscreen reactivating but honestly it's worth it to me to have a phone that lasts.

The issue is with the battery drivers, nothing else, your "fix" are just ways to increase battery life

Thunderbolt overheating?

I woke up this morning at 5am an found that my Thunderbolt was running very hot. 60 degrees Celsius to be exact and the phones charging led was flashing from amber to green very quickly. I pulled the phone off its stock charger and pulled the battery to find that the battery its self was very hot and even producing and odd smell. I let the phone cool for five mins an once cold to the touch, I installed my spare battery and with heavy use, I am back to running temp of 34c and not sure what caused this??? Phone is rooted an running Bamf 1.6.2 overclocked to 1.4 and has been running like this since may 5th with no issues. I have noticed in the past two days, so very rapid battery drain but haven't installed anything new and i have all HTC sense apps not syncing... Any ideas?

Do you use SetCPU to overclock? I would recommend it, as I think it would've prevented your phone from overheating.
I have 3 profiles set up, and then have the overall max set to 1.4ghz and min set to 245mhz using Smartass. I've found it's always a good idea to have a profile set up to limit the overclocking when the temperature is >50C, to prevent damage to the CPU. I have a profile to limit the max OC when the phone is charging, to help prevent it from overheating. I also use a profile to limit the max when the screen is off, since you don't need the extra speed then, and it helps on battery life. My profiles are:
Temp > 50C - Max=768; Min=245
Screen Off - Max=368; Min=245
Charging - Max=1024; Min=245
Just set up all these profiles and even added another. Thanks for the tip! I hope this helps with battery life also.

Are any of the governors better than the others for handling this?
The goverer used really depends on your own personal usage of the phone. Experment and see which works best for you. FWIW I use interactive and am pretty happy with it.
Ill try that one out. I found Ondemand to waste too much battery, and smartass to be passable.
i just had something weird happen myself. i just installed NONS3NS3 rom and then 'adownloader'. had it downloading a file then all of a sudden the phone locked up and was completely unresponsive. i pulled the battery and it was incredibly hot. waited for it to cool down and now everything is normal again. bizarre, because i could use adownloader just fine when i was on CM7.
My phone gets warm to when i charge it but not 60c. The kernel can cause this too.

I would probably not use that battery again. Sounds like it crapped out on you. 2 days of decreasing battery life, than that...

I don't think the battery has any issue. When a Li-on battery fails, it will create a lot of heat, but it will also alter the resistance and voltage characteristics in ways the phone will detect.
If SetCPU resolved the issue, then you've got an issue with your ROM. It shouldn't do that under normal circumstances, and even if you're using SetCPU, something is still trying to use resources abusively. I'd try a different ROM or radio and get SetCPU off of there. It's actually abusive in itself with resources. It's great for testing OC settings, but for long term implementations of settings, a script is the ideal tool for the job as it implements setting directly to the kernel with no further intervention.

Thunderbolt battery...lol

So I know this subject has been hashed a thousand times. But... My tb was actually getting fantastic battery. Ten hours without charging. Right now I'm on the latest thundersense, no OC, conservative scaling, juice defender ultimate with data off when the screen's off, and my battery went from 100% to 49% in two hours. Am I doing something wrong, or did I just not quite understand that one day my phone turns on and says "I'm going to have terrible battery life from now on"? Because that's literally what happened. One day I was bragging about how fantastic my battery life is, the next was like I got blindsided by a mugger.

Charge it fully, calibrate the battery.
I will try that and post back if I have any issues.

Sorry for being a newb, but I keep on hearing about calibrating the battery in these forums. How do I do that?

Download Battery Calibration from the Market. It's free. Open the app, it notifies you when you're charged to 100%, hit the calibrate button and you're done. Simple as that.
I had the same problem and set a profile in setCPU to have max and min cpu speed at 245 while the screen is off. Used onDemand at 1.28 i believe and I went from charging by 4pm to still at 50% by midnight. It really was night and day.

One thing I'm having trouble with understanding is the governors. I'm using smartass right now with no profiles. Will it underclock the phone to 245 when the screen is off? I read an article that said it didn't need profiles so I assumed it did this automatically.
i never expected fantastic battery just equivalent to my Dinc which is 9 hrs, on average i get 8 with my TB so it works for me
I get quite good battery out of my Thunderbolt. I ran it on stock battery with light usage almost 60 hours before I needed to charge.

To op first I would ditch juice defender never been a fan of that app plus it also takes resources to enable data again seems counter productive somewhat. Second it does seem these phones have days where they suck down the juice. Also I would use ondemand instead of conservative I have never seen one person even back to my Droid that said they had amazing battery on conservative scaling. I notice way to much lag with conservative as we its only supposed to scale up to the clock speed needed but it takes to long to scale up in my opinion. I've always gotten decent battery life from Droid to thunderbolt and I've always used ondemand with the min clock speed when screen off. Also if you dont have spareparts get it from the market it may have been a rogue app for some reason that day. I have Google voice act up on me from time to time. Hope this helps. Oh and I'm getting 20 to 30 hours out of mine. Whoever said 60 hours must have it hooked up to a car battery haha.

I don't know about 60 hours on this phone yet. I have gotten 2 days with small usage, but not longer. This might be doable when CM7 starts getting nightly cranked out. Or when our AOSP kernels get better. That is when I started getting 3 days with my evo, but then again, that was with 3G only.
Ever since I did the battery calibration, it seems a lot better. I tend to flipflop back and forth between conservative and ondemand with my main profile- I wouldn't say conservative is a total waste, I'll reserve that for the powersave scaling. So in any case, was it just bad values were written to the batterystats.bin file? And if so, what steps can I take to keep it from happening again? Other than this little bump, I'd say the tb has been the best phone I've ever owned.

[Q] Weird battery drain

So I've been having some weird battery drain the past couple of weeks. I have been trying to watch it and try to find the source of it but cannot seem to nail it down. I dont get that spectacular of battery life overall. First off, I am running zeus v6 with kl2 modem and nothing else done and no overclocking. Battery drain seems high overall, but above 50% battery its not too bad, however once it gets below about 50% battery the drain noticeably increases. Today for example, I unplugged my phone at about 8am, light usage pretty much all day, at 4 or 430pm it was about 50%, I get out of class at 7pm and the battery is down to 20%. Only thing I noticed was that I turned wifi on and left it on but it was connected to a network the whole time so its not like it was searching for a network. I had only about an hour of screen time, maybe a bit more. Its like this every day no matter what I do. I rarely get over 12hrs of battery life. I even got a new oem battery 3 or 4 weeks ago to see if that help but it hasnt much. I'm starting to wonder if it might be related to my phone that I just dont get as good of battery life? Not sure what to think, Im going to try flashing another GB rom in the next couple of days to see if that changes anything. I will post some screenshots of my battery life later tonight for you guys to look at. Let me know if there is anything else you want to know. Anyone else experiencing weird drain like this?
http://forum.xda-developers.com/showthread.php?t=1408433
I had tried the two most recent versions of Zeus, and had unbelievably high battery drain. No WiFi or GPS use at all. If I was actively using the phone, my battery power would drop at roughly 1% every minute or two. And that's with screen brightness turned all the way down. Even with the screen off, it was pretty bad. I'd lose something like 7% an hour, with the phone sitting unused. I had basically the same results with Saurom. I pretty much just chalked it up to something within the ROMs themselves. I get great battery life with stock GB, CM7.2, and Paranoid Android JB.
I was reading that thread you posted qkster and it didn't really seem to be having the same issues as were in that thread. It's more just like no matter what I do the battery drains normally above 50% but below that it drains way faster even with less usage and not doing anything different.

Battery life problems.

Hello, I'm currently running cm 9, however the battery life is just awful
When the phone is on sleep it loses like 1 percent every 5-10 minutes
I am using an extended battery as well, please tell me what to do I was on GB before and the battery was outstanding, I could go on one charge the whole day with heavy usage, now i dont think I can make it through the day with light usage on this
thank you
EDIT: This could be a sleep problem, because when the device is on, the battery is normal
If you flashed the Feb 27 cm9 you should flash proton kernel so you can watch videos. Battery life isn't as good as gb no matter what you do. Also give it some time to settle in. It takes more than a couple hours.
alright thank you... I just flashed the newest version of cm9 a few hours ago, I was flashing a bunch of roms and this one seemed the best... do you know how to force a device into deep sleep cause that seems to be the problem i believe
OK I was just on 20 percent, then i rebooted my phone, and now im on 2 percent... im seriously considering going back to gb
Sounds more like a battery thing? With CM9.? + Proton I'm getting at least a day* with light use. Maybe a bad app or combo of apps? What does BBS say is eating the charge?
* - I say at least a day because I can't not use it for that long.

just the screen and the android system... very interesting thing though is happening
I'm running a bunch of quadrants to get the battery down to 0, and the battery is all the way down to 1%, however it's been on 1% for like 6 quadrant tests... maybe its just a problem with the indicator, however another indicator also says it's at 1%... very interesting
If you are on CM9, I suggest you flash Hefe or Proton.
I use Hefe because according to the posts being made it puts your phone into deep sleep, which means longer battery life.

Definitely a battery problem. This happens to me on one of my batteries but not on another. Time to buy a new one. I haven't tested it fully but it does appear to be just a display issue. Sometimes the bad battery will make the phone display 1% but it will still act as if it had way more than 1% charge left. I haven't done any testing on that regard but that's what it appears to do.

I don't believe it to be a battery problem, because I've been on GB with absolutely no problems and exceptional battery... I just upgraded to ics not long ago, and the battery life instantly screwed up
Have you set the cpu governor to anything silly like performance?
Have you let it charge up fully at least once?
Search xda for "better battery stats" app, use it to see if you're getting deep sleep.
Flash hefe over release 8 and youll have a little better battery. Proton doesnt deep sleep
Sent from my SGH-T959V using Tapatalk 2
Proton DOES deep sleep. That was one of its major features.
Certain scheduler/governor combinations work better on different kernels, though. If the specific one you like most sleeps better on Hefe, great. If the one you like does best on Proton, great. Just be aware that most issues are either physical or user-inflicted...
In this case, your battery is almost certainly dying. The variance in power over a reboot is a definite tell that your battery is probably swollen. If you can spin it on a table, the cells are starting to die. This does not mean you can't keep using it, but it does mean that your battery life will be irregular. It also means that you'll have significantly "higher" battery levels if you reboot the phone with external power connected, but the battery will discharge very quickly if it hasn't actually reached whatever level it believes it should be at.

Bad battery life?

Anyone else having terrible battery life? I'm running stock with francos kernel and it's very lackluster to say the least. Even with the stock kernel it was not impressive at all. On my G2, that has a smaller battery and an older processor I got almost 24-26 hours with anywhere from 5-7 SOT hours consistently. Granted the G2 has a slightly smaller screen, I don't see that making much of a difference. This phone has a 3100 mah as opposed to the G2 3000 and has a newer 801 which is supposed to be a power sipper, as opposed to the G2's 800. I'm currently at 7 hours of battery time with 37 minutes of SOT and sitting at 81%, which is god awful. I mean the phone so far idols terribly and battery drains fairly quick while not being used, I checked battery stats and there's nothing out of the ordinary. I just don't understand how a 3100 mah battery with an 801 can be so lackluster.
Also I took these two pics, something's wrong here. Stand by is definitely something my phone was a lot but it should not be the reason for that much percent of the battery. I've never had a phone with stand by taking that much battery, screen is usually always by far the highest % even with not much sot, and I was in a area where I've always had reception so not sure why it had to search for 15% of the time.

Does anyone have an idea? Could it be kernel related? I'm on the Franco r7. I've never had a phone ever that used so much battery so quickly on being idle and on stand by.
