Battery Graph Misreporting?

Disclaimer: This is not not supposed to be another battery life issues thread.
So! I have been noticing that my nexus has been showing a slight increase in available charge without being plugged in. I never noticed this occurring on my thunderbolt and my old touch never made it that far along so I can't compare it to that.
I have calibrated my battery 3 times since I bought it and have been swapping ROMs. I am currently running Android Revolution 2.1.2.
Does anyone know what might be happening?

It happens. It's normal. Sometimes you demand too much of your battery. It heats up losing a little voltage but gains a little back when it cools down. Another epic reason uv'ing is valuable. Lower heat. It also extends longevity of electronics and your battery.

Its just voltage being under load and then being relaxed so it pops up a bit. Some phones exhibit this and some don't. It all depends on the type of battery driver used. Some like the max17040 use voltage to determine SOC and some use strictly coulomb counting which don't have this bounce effect. Most Samsung phones use the max17xxx fuel gauge using voltage, and most HTC phones use ds2784 and similar which just counts current, so no bounce.

Thanks guys, I had a feeling it was something like this. Thanks for all the info, especially the stuff about the drivers. I find it fascinating how something like the way a charge is measured can cause effects like this.

SetCPU profiles?

Hello all... I'm new to Setcpu and have been able figure out how to OC and UV while still keeping everything relatively stable. As of now I'm experimenting with making profiles, I was wondering if someone could post a screen shoot of their profiles and pass on any advice. I am running TNZ Blend 2.6.2 with the Hitman kernel. Here's a screen shot of what I have so far.

The only thing I would comment on is your "screen off" there is no reason for it to be scaling/jumping from 800-1200 "ondemand" while the phone is not being used or the screen is off in general, just have 800 low and high or have 800 as your high and set it to "performance" so that there is no polling being done and it will set itself to the high value which would still be 800 anyway.
You might have a reason for that setting, just trying to save you a little bit more of battery juice.

Definitely bring down that screen off! I have mine set to 200-500 ondemand. I'm sure it'll save you a lot of battery. Also the battery 100% is kinda pointless because that's what the main profile is for. And expect your phone to get extremely hot if you use it while charging since you have it overclocked. I did that same mistake now I keep it at 200-800 to avoid the over heating.

Just a recommendation...you should give tegrak a go. I find it to be much more beneficial than setcpu...

Why scale cpu depending on the battery level? I prefer scaling CPU on my phone by the temperature. 1.6Ghz normal usage and then gradually scale it down if it gets too hot. I bought this phone for its performance, not battery life, which actually is pretty amazing for such powerful device.

be careful with Tegrak, as it doesn't work with some of the non stock kernels, and will freeze your phone for sure..

Pretty good. You don't need the battery>100% profile. Adjust that from the main page.

Yikes! I wasn't aware of that. Guess I'll do a bit more research on that before I fire out recommendations. Note to self...not all devices have the same setup as yours

Slow/Laggy CM9 Nightly Fix!

I'm not sure if anyone else was experiencing lag from the new CM9 Nightly like I was after I flashed it.. So I played around with the options and noticed that the CPU governor under "Performance" was set to "Interactive". I switched this to "On Demand" & checked "Set on Boot" and man this phone flies now! Also make sure that the min and max speeds are set correctly.

I dunno, maybe your battery life is going to suck now lol. Let us know how the drain is. If I weren't at work right now I'd be playing with the latest nightly myself.

CM9 is Great! Flashing LU6200 and used X2.

You have succesfully flashed CM9 on LU6200 ?

On demand governor draining more battery then interactive one?

Much snappier for me too. Can't report on how it affects battery life yet. With this phone and the newness of the ROM, definitely keep your charger handy.

thank you, I made these changes.
I did a bit of the google to try and find the difference between interactive and on-demand, the nomenclature sure seems similar, but could not find any descriptions of the 2, anybody know?

http://wiki.rootzwiki.com/CPU_Governors
Ondemand
Quickly scales up the CPU frequency once there is sufficient load, and then quickly scales down the frequency once the load is no longer present.
* Pro: Good performance, decent battery life.
* Con: CPU frequency can constantly shoot up and down, causing more power drain than staying at an "ideal" frequency.
Interactive
Quickly ramps up to the maximum allowed frequency, then slowly drops the frequency once no longer under load.
* Pro: Faster to ramp up and down means a snappier response from the device.
* Con: CPU will run quickly for a few moments after it is no longer needed to do so, resulting in longer periods of higher power consumption and heat generation.

I don't notice a major difference in battery drain yet. Still mediocre. But I am willing to sacrifice some life for the absence of lag. I almost reverted back to gingerbread before discovering this minor change fix lol.

Thanks Namuna

THANK YOU VERY MUCH FOR THIS
actually i have a much better battery right now and an almost lag free phone !

I do not recommend enabling KSM as posted above. I found out that ksmd process utilizes cpu by 3-5% for hours!!! It drain battery on my eyes!

Battery drain on 4.2.2

Been having battery issues ever since I flashed a 4.2.2 ROM.. I think its the modem. Being on like over drive, draining my batt.
Or is it 4.2.2? I tried all the 4.2.2 Roms that there is for our phone. And its seems to drain at the same rate every time. I don't know of its just me or can my radio be the cause of it. Or android 4.2.2??

Battery Drain......?! Try Battery Not Holding Any Charge!
I've kind of got a similar problem. Can't quite figure out what is causing it though. Everything was fine until I updated to tha latest nightly last night. It slowly took a nose dive after that. It actually died all the way out on me while sitting plugged in. Now, as I stated in the title, it won't hold any sort of a charge whatsoever. Every once in a while I can get it to boot up but almost instantly it shuts right back own. Can't seem to boot into recovery either, but have gotten it into Download Mode pretty easily. That's where it'll remain on for the longest duration, but still not long enough to be able to reflash anything to it. The battery state check said the battery health was good all the way until it completely died on me the first time. There has been no moisture or other damage done to it in an kind of way either. Any ideas as to what exactly the issue at hand may be?

Sounds like it might be your battery...know anyone with an s3 that you can use there battery for a bit to see if it charges...if so then its your battery if not might be the ROM or phone.

I'm running the most recent PACman ROM, which is 4.2.2 and what I do is set my governor to interactive and my I/O Scheduler to SIO. Running stock kernel at the lowest min and highest max, I can get almost a day and a half out of a charge. My trick is to toggle things when I'm not using them. I mean all the time. Screen brightness never above halfway, no haptic feedback, no live wallpapers, and I'm always clearing my recent apps. I don't know if this'll help you any but that's my battery saving procedure.

I really don't know anyone with an s3. Seems Apple has everyone around here convinced they're better. HA HA! That's a great laugh! Seriously though, there is a used cell phone shop I'll go talk to though. As for my kernel settings go I run interactive, on demand, 648 & 2100, under volt everything 100, and either raise or lower all other settings within one point from the least or maximum it could be. Been running that since I got the phone in September without any problems battery wise whatsoever. I'll start with checking the battery though and see where that journey leads....... Thanks for the thoughts and suggestions.

Temperature goes too HOT!!!

Hello everyone, I just bought my G3 3 days ago. But the temperature seems bad for me.
The CPU temperature is between 54C and 68C in normal use (Facebook app, messenger) and it reaches 75C in heavy use (Shadow Fight 2, VR Games, screen brightness +80%, Google chrome). The battery is something cooler, but I think it is in bad situation too. Its temperature in normal use is between 36C and 38C and in heavy use it reaches 40C. What should I do?
- The apps I have used are (Antutu Benchmarks and CPU Temp).
- I did not make any changes in software or even hardware.
- My phone runs at Lollipop V5.0 OS.
- When the temperature of CPU reaches 70C, I can't make the brightness +90%.
- Sorry for my English.

this works like a charm for me! but if you will do it, do carefully to dont damage the board!

I was thinking to return the phone, specially it just 3 days ago, as I don't want to open the phone.

no difference because it will happen the same on next phone, its a issue of the processor itself because the gap between the processor and the frame of phone! all stock LG G3 have this issue.
sure, you do what is the best for you, mine have only 2 months and i do this anyway...have no fear to loose the guarantee!

You should buy a portable console, maybe.

Noob. My G3 can be at 101ºC

I gonna call firefighter T.T

Basicly u need to root use a diffrent kernal than stock most have built in thermal mods plus the thermal paste mod i get 62 max

you should also try using ctt thermal mod.root your device.istall twrp and flash that mod in twrp and you are good to go.i dont know how low temps you will get after that but it does help in lowering cpu temp.try it.

mcafee....
