Is it a good idea to use this to calibrate my batt now that I have so much stuff running in my handset?
Seems like it's better to do a calibration when freshly flashed

that's what i'd recommend you. battery stats easily get f***ed up after flashing. just get battery calibration or wipe battery stats in cwm. you will see results after 2 or 3 days. u have to do that everytime u flash tho...

Thanks, I was just wondering though, is it ok to battery calibrate halfway through using the phone?
I hard-resetted the phone upon getting it. Does this f***k up the stats? I didn't flash new ROM. Just CF rooted, that's all
Hey guys I'm kind of new to the rom world and let me say i LOVE IT. So much stuff you can do with the android. I'm on a i747 galaxy s3 and I've just downloaded the Pacman rom.I've downloaded other roms so i know i flashed this one correctly. I even re flashed it again last night. Both yesterday and tonight my battery went to 100%-%50 in one hour. After i charged it up it would decline 20 percent in one hour. I look at the time screen time on and to see if anything is waking up my phone excessively. And all sings say to no. Any tips? I feel like I'm back in pre ics days haha.

when you flash a new ROM it is recommended to wipe Cache, Dalvik, Factory Reset and System. If you've done that you should be okay with the installation portion.
Have you modified the kernel at all, have you over clocked anything?
Go to the play store and download BetterBatteryStats. This will help you determine the cause.

Yeah i have. When i installed i did the whole wipe thing. And I'm useing gsm batter monitor. All the readings are normal which is the weird part to me. And no i haven't over clocked (No need to imo) and haven't modified the kernel. I know that on previous androids you would have to do a wipe batter stats. I actually tried looking for that in CMW but i wasn't able to find it. Would you have to wipe the battery stats using "batter calibration" or wiping it manually in CMW? Or is that even necessary for galaxy s3s?

I would also recommend using Better Battery Stats as it is the best one I think. I always use the battery calibration app after I flash a new ROM. It usually takes a couple days or so anyways to have the new ROM settle in and everything. After a couple days you should see your battery life where it should be and not draining so fast depending on what your settings are.
Battery calibration is a myth and has been confirmed by Google themselves. Its all over the forum and wholly unnecessary. Those apps are useless. The only way to truly let your battery stats "calibrate" is to let the ROM and kernel settle into the phone after a few charge cycles.
Here's the Google+ discussion by one of Google's people: https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
If you want to keep "calibrating" your battery for the warm and fuzzies, its your time and device.

Wow thats interesting. Everywhere i go people say that battery calibration is a necessary part when switching roms. Just out of curiosity what do you do for better battery life ? Basically what you use and not use settings wise.

Everyone's battery life varies. Honestly, it doesn't matter the ROM. The kernel does play a part in it but its how YOU use the phone, display brightness, sync, etc. Way too many factors.
As for me, I get about the same life on most ROM's I use after letting the phone settle for a few days. The only constant I have is the kernel I use which is in my signature. Lately, I've settled on one ROM as the dev is on top of his game with this device. That ROM is also in my sig.
As per title. Battery will drain .... Quickly !!! Then when I plug in to charge it instantly changes to over 50% charged. It will then charge to 100 (which I guess is actually less than 50% in reality).
I have tried various ROMs. I believe the battery is empty, just don't understand the instant reading of over 50% ??
I would assume the battery is done for. But I would try to drain battery boot into recovery And wipe battery stats. I've heard wiping the stats doesn't ddo anything useful..but its worth a shot.

Thanks. I was going to try resetting the stats but so many people say that does nothing .,... Have tried flashing 4.3 and will see if that kick starts the battery again.

Let us know how it goes, I've noticed my stock battery lasts about the same amount of time as my extended because I've used my extended the whole time I've had this phone. Good luck: 4.3 is slick

A full wipe and flash to 4.3 has managed to clear it.... Next dilemma though I've been offered a 4 month early upgrade to an s4 ..... With the x phone disappointing (IMHO) I'm not sure what else is worth waiting for

As the title said, i'm looking for a kernel to improve my nexus 7 battery life. I do not play games, my most concern is improve battery life when browsing web. Anyone can help me? I'm quite busy so i don't have time to try every kernel.
Thanks in advance

Screen on time is taking about 20% instead of the 60% I used to have ( I normally have it on lowest settings). Lasts me a day without charging.

This of course is BS, a kernel can't alter the percentage the screen uses in such a ludicrous amount. But if it works for you, great :angel:

Kernels can affect screen time in "ludicrous amount" when you overclock, use the device for a period of time, application usage, GPS, Bluetooth, and display settings etc.

No. Not in the amount you specified. Complete nonsense, with all due respect. Underclocking, undervolting, all those things will never yield your result. One hundred percent impossible.

Well I don't know what to say to this. I know what my battery stats were and I wipe them (and I continue to wipe them) daily. Maybe my nexus is special. Come to think of it, it has had some problems before. Maybe this is a way for it to make up to me

Its true, battery stats have no effect on battery life. I wipe them across ROMS because the battery stats file can get messed up when switching ( it has happened to me before ).

No, it can't. Wiping battery stats has no influence over the battery indication whatsoever. As per Google themselves.

I never said that the battery stats file had influence over battery indication. Like in the link you provided :

That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."

Interesting things happen when you wipe the cache. This is from my Nexus 7 during Video playback. Seem like the battery consumption gets attributed differently.
Exactly the same setting, ROM & Kernel, both cases I use MX Player Pro with H/W+ accleration to playback 720p videos. Only difference is in first case Screen battery consumption 83.5%, the other 57.7%.

Get Elemental X 1.8 and run it at stock clocks (1.5Ghz CPU/400mhz GPU) will probably give you the best battery life. If adjusting a lot of settings when installing a kernel is a hassle to you, get Bulletproof 1.3 instead. Bulletproof have the same developer(flar2) as Elemental X, it is basically a developer optimized version of Elemental X running stock clocks & optimized for Battery life.

I wipe them because like I said before, the file can get messed up when switching ROMS. It got messed up on my LG phone before so I wipe just to be thorough.

Thought so. Unclear answer as you don't have anything conclusive to say.
Just keep on wiping, it's highly recommended :good:
Hi guys -
So I saw in one of the 4.4 ROM threads that someone had used the Battery Calibration app from the Play Store and they claimed it seriously helped their battery life on the geespr. I decided to look at the app in the Store, and I started reading the reviews. I'm perplexed - - many people gave five star reviews claiming it significantly improved their battery life, while others said it did nothing, and a few even said it made their battery WORSE. Then there's the few who have said that wiping the battery stats file (the function that the app fulfills) can't possibly make a difference to your battery life because it only affects how Android reports the battery info. Still further, some say that the battery stats are ALREADY wiped when you flash a new ROM or even just unplug your charger.
So how about it, guys? Can we get a definitive answer about this? Surely our talented devs know the truth?

I've been confused by the same thing. I usually recommend doing it when switching between roms. While I can't give you a definite answer, I have also read that wiping the batterystats.bin file does nothing. This thread here says it does absolutely nothing and explains why. That being said, I am one of the people who have noticed significant increases in battery performance from it - which is why I recommend it. Apparently it shouldn't work though! So now the real question is, why the hell did my battery performance increase to such a high degree afterwards, if it does nothing? I didn't use the app, I just deleted the file once my phone hit 100%.
That thread I posted states it is clearly a placebo, and is even backed up by google. It won't hurt so I still do it because like I said Ive noticed an increase. Now Im completely unsure as to why that increase has taken place.
The app also says to let your phone drain to 0% and then recharge uninterrupted back to 100%. It says that it isn't necessary but helpful. Now this could help your battery IF it was a nickel based battery. Since ours in Lithium based, it can actually hurt performance and shorten your batteries life span.

Yeah, it appears as if it is simply a placebo. That thread is clear on what that file does and it shouldn't affect performance. Perhaps my increases happened because of changes in charging that just happened to coincide with wiping that file? What I do know is that I was regularly getting 15 hours or so with moderate use. Afterwards it doubled. The longest this battery has lasted for me was a little over 30 hours on a full charge.

It must just be a combination of factors then...which would explain why some people say it helps and some people say it hurts. Seems there's no real clear trend. Thanks for your replies
