is it just me or is the kitkat ROM really sucks----battery pretty well?
I also notice that the CPU usage does not drop to 20 percent idle but when I used other ROM (JB based) it becomes 5 percent.
RAM usage is good but I think it hogs the CPU. I used cpuz on measuring the cpu usage

Where can I get the JB rom for OGP?
For me, Android was best at JB and went backwards with KK.
Yes, I've noticed absolutely horrible battery life with KK. KK just feels like it is several different parts all just thrown together.
The only reason I think is that theoretically JB uses more battery is that the system uses more voltage than the kitkat. however, what's less voltage use if the CPU is always busy and wakeups are just everywhere.
Hi guys, maybe you could post in some battery stats so we could know more about whats draining your battery in particular and suggest some fixes. I've actually experienced the opposite with kitkat-battery life for me improved. There was even an instance that I got the phone to last 30 hours, with 5 hours, 48 mins. screen. On another instance I got 15 hours life and 5 hours 25 mins screen on. I just lost the screenshots as I had to reflash stock when i was doing some G3 mods., but nevertheless i could post some new ones.
I value batter life was well and i'm curious to see how yours could be improved too..

What a battery life. 15 hours screen time?
how can we accurately measure? because I only use CPU-Z and installed DS battery saver to save power. right now it only used 2% of my battery during the night. (from 1:45 - 5:50am)
I see. can you tell me what app should I use to determine CPU usage of each app/service?

No, my battery lasted 15 hours, and my screen-on time (total time i spent using the phone) was 5+ hours coz i basically used my phone then for gaming the whole day I suggest you download gsam battery monitor app (it also has a temperature_bat. Usage graph), as well as wakelock detector. Another alternative would be better battery stats. What you would need to observe would be the apps and wakelocks draining your battery both when you are using your phone, and also when its idle.
I also notice that battery capacity is 2A in which it should be 3.140A right?
this shows on kitKat but on jellybean, it's 3.140A again.
is there something wrong with the detection of battery capacity?

What happened was that in kitkat, the permisssions required to be able to access battery stat files changed. Thus, apps w/c could freely access the batter stats in JB cannot gain complete access in Kitkat. This is the case for some battery monitor apps w/c now have lesser accuracy in reporting battery. No worries though, as there are means to bypass this problem. If you have xposed you could install a module for this. Also, some apps like gsam battery monitor come with a separate root companion app. Once you install those batter stats will be accurate.
Here's a screenshot of my battery stats for today..might not be 5+ hrs of screen on as i did a lot of rebooting today (themed with g3 tweaksbox). Nevertheless, this is just to show that kitkat has the potential to provide good battery life. Also enclosed is a screenshot of one of the battery apps i use, gsam.
Hey everybody! I have some findings I absolutely must share so you can benefit as well.
I've been doing some tinkering and I've find a way to significantly increase battery life on the OGP.
First thing you'll want to do is put your phone into airplane mode.
Second, turn your screen brightness down as low as it will go. I mean, all of the way down.
Third, don't play any games on your phone.
Try those three tweaks and see what kind of battery improvement you get.

Just so you know, first my cell radio and wifi were both on the whole time. Second, i was on auto brightness the whole time. Third, i played clash of clans as you see in there.
If you have not done this already, adjust your cpu to save your battery juice. Set the cpu governor to powersaver or interactive mode if you just using the phone to send msg and make calls. I let my phone run on msm-dvcs and when I'm not plug in. Check out ROM toolbox if you're rooted. Seriously folks, instead of complaint about how much the roms suck the juice, try these different ways to see they make any difference for you.

That's pretty much a tablet use. You want great battery buy a zero lemon battery, the bulk is worth it, I got 3 days with very heavy use

I found a way to make my phone last a long time. I just turn my phone off and don't use it. I wish I would have though of this sooner.

Hi,
I have noticed that my battery is getting eaten very fast recently. I used to have the energy consumption around 3%/h now I am having it closer to 7%-9%. According to the battery usage overview my watch will last for 12 hours - that's definitely too little. I guess a part of this added consumption could be attributed to AutoWear but I doubt it is so much. What is puzzling me is that the energy consumption attributed to particular apps does not even add to half of the consumed energy as on the attached screenshot.
The total consumption of apps listed there is 10% whereas my battery is at 61% - where did the other 29% go? Any ideas would be welcome

I noticed similar battery drain on my SW3 under certain circumstances. I did some experimentation to figure out what was causing it, and my biggest culprit turned out to be the watch face! I designed several custom watch faces in Facer and Watchmaker, and both were consuming 6-9% per hour. I even cut back on details, got rid of things like weather and temperature updates, etc, and still the battery wouldn't last a full day. I didn't like any of the stock watch faces, and was overwhelmed with the selection of 3rd-party ones, so I kept at it. Eventually I settled on Intellicom Watch Face. It doesn't give you anywhere near the customizability of the other apps out there, but boy did it do wonders for my battery! I have a simple watch face now that gives me time, date, and battery percentage (only date and time in ambient mode). I get several alerts an hour, all day long. They vibrate and light up the screen. I have motion detection turned off (where the backlight turns on when I twist my wrist). I also use Google Now 5-10 times a day for reminders or replying to text. Now I get two full days of battery life if I turn it off while I'm sleeping. Also, try turning off auto brightness and set to the lowest level. With the transflective sceen, that's all you ever need really. Not sure how much a difference that makes, but it can't hurt, right?
Autowear
This is because of autowear. A screenshot from google play. Seems the developer does not have a current plan to fix the problem...

Some apps eat the battery I had this problem uninstalled the rogue app and my battery life recovered.
I do not know what AutoWear does to battery life but if it was the last thing you installed, I recommend getting rid of it and seeing if it helps.
Hey, everyone!
So my phone's been having a few issues, and I've been trying to figure out the cause, but to no avail.
I've had my S3 for about a year (ran stock ROM for a month, then switched to Paranoid, then Quantum, and now SlimKat) and I noticed my battery life decreased significantly, namely after I started using Fast Charge, so I promptly disabled that. I used to be able to leave my phone on idle for about 2 days at a time before the battery finally gave out, and recently my battery was barely lasting 3 hours, which really isn't good. I'd charge my phone to 100%, go to sleep, and by the time I woke up (I sleep on average 8 hours) my phone would be completely dead.
I bought a replacement battery (of which I'm pretty sure is genuine, but there's no real knowing), but I noticed my battery's still draining pretty quickly. More specifically, according to BetterBatteryStats, it's draining at 8.4%/hr on idle. My phone's gone from 98% to 75% in the last 2 hours with me only turning the screen on three times for the span of maybe 5 seconds each to check the battery level.
Any recommendations? I charge my phone with my PC and PS3 via USB with two different cables, if that's relevant at all.
Also, the apps I have installed are Skype, Facebook, BBS, Chrome, Snapchat, and a bunch of games to keep me entertained on long bus rides.
Also, for those with Bell, how much would they charge to possibly replace the phone in case someone else is going? I still have a year before my contract allows me to get a new phone.
My current phone is the I747M, running the latest SlimKat version and kernel.
Attached are screenshots from BetterBatteryStats.
UPDATE: I ended up installing QuantumROM again, plus the latest LeanKernel, and I went from 80% battery to 20% battery idle in the span of 12 hours, which isn't as nice as I'd like, but is LEAGUES better than it was, considering it used to completely die in 4-5 hours of idle time.
Any tips to squeeze out a bit more battery life without sacrificing a ton of performance? My governor is interactiveX and my scheduler is ROW.

It sounds like something is keeping your phone from getting into deep sleep. That program will help you find it. Figure out what is causing the wakelock and you can probably use privacy guard in your ROM to block wake up / keep awake for that app or service.
From what I've checked, it seems to be from Google Play Services, but I've done everything in the book (Wakelock Terminator, running an init.d script to disable Google Play Services, etc.) but I'm still running into issues. and SystemUpdateService is 88% of why my phone's not going into deep sleep. The other two are AudioMix (5%) and google.android.gms ConfigFetchService (2%).
Any suggestions?
I have same issues using quantum rom,I switched to touchwiz roms because they are more battery efficient, 8% / hour is not normal,My battery drains 1-2% / 6 hr ( with flight mode) in touchwiz roms.

I've never run quantum, but if it has privacy guard you can use that to block this. In privacy guard enable showing built in apps. Find Google play services in the list and long press it. In the list that opens deny keep awake and wake up for Google play services.
I've always got the best battery life out of ROMs based directly on aosp like slim. Cm and other cm based ROMs are a close second.
Thanks for the suggestions, everyone!
I ended up figuring out some weird convoluted way to disable Google Play Services, but something's still preventing me from deep sleeping completely. When I checked this morning, my Deep Sleep was at 66% (better than 0) and I only lost about 10-15% battery.
I'll keep you all updated!
Hello,
I am trying to monitor my battery consumption over the days. I have an excel sheet an I report regularly the battery %, the SOT, the drains,....
I applied different OS, different kernels (stock, EXKM), Greenify or not,... and I monitor my battery.
I do that at least 2 or 3 days for every cases in order to have a significant daily usage with less usage variance as possible.
Then I generate an average consumption curve to calculate max expected SOT. Target obviously is to get the best combination of OS, kernel,... for best battery consumption.
But it takes time.....more than 2 weeks now I am doing that....
I am wondering what soft I could use that simulates a "normal" usage of the phone. Not AnTuTu like software that evaluates the performance, but a soft that runs the phone normally, with a routine that leaves the screen on, runs the CPU at moderate level, times to times at high level as you were playing to a game, access internet as you were surfing,.....
A soft that you adjust according to a kind of user usage profile and I can leave my phone on the table (while I am working ) to drain my battery and to have a complete set of full cycle battery datas in 4hrs (max SOT I got) instead of in 24hrs of phone usage.
I hope I am clear :fingers-crossed:
Thank you for your help.
I am actually looking for the same thing to test some phones at work. Did you find anything yet?
I'm new to my Pixel 2 XL and have the 8.1 update and am seeing horrible battery life. Noticed others in here also experiencing this and wondered if any of you have some recommended settings for EX Kernel that can improve battery life? I only use the phone for notes, camera, calls, messages, etc... Daily use type of stuff. I don't play any games on my phone other than Hearthstone and it doesn't require much to be smooth and I watch some YouTube here and there but it also doesn't require much so anything I can do to get those 6 hour SoTs everyone raves about with this phone.
Standby is great, in use is just embarrassing.
Mine is opposite. It easy to get 6 or more hours SOT using the phone but the thing drops like 10% battery overnight even with battery and data saver on.

Well that's not good. I would much rather deal with on drain than stand-by.

A kernel will not stop a badly behaving app from drawing too much power, or not dozing when it is supposed to. You would be better served in using a battery drain app to find your wakelock/bad actors and deal with them. Beyond the information you can get from the improved Google battery applet, GSam and BBS are two apps that can help pinpoint the application or service causing excessive battery drain. It is not the kernel, and as flar2 states, the new chips are so efficient with power there is almost no room for improvement battery-wise. Most people leave it on the default settings, and use it for extra features and customization.
https://elementalx.org/the-truth-about-kernels-and-battery-life/
I agree 100%, I just thought some settings adjustments with the kernel could do some good and maybe someone might have some ideas on what would help the in-use battery consumption. I'm currently clean flashed with only Google APPs and Nova Launcher installed along with EX Kernel and Magisk no modules. Battery drain only shows android system... Not a lot to tell me what it really is. Will try the apps you suggest
