I installed Quantum 3.15 ROM a few days ago with decimalman's kernel.
I am getting battery drain with my phone doing nothing at a rate of 7-8% per hour. BBS lists the PowerManagerService.wakelock at the top of the kernel wakelock section. A little research tells me this is a placeholder for all partial wakelocks. Problem is, partial wakelocks lists nothing. So I have no idea what is really going on. Can anyone give me some advice where to look next?

+1 Having the same question. About to post but turns out you have already post it :good:
Exactly the same situation tho my battery did not drain that much but still found the powermanagerservice and main kernel wakelock had been running very long time, while partial wakelock had very few awake. Any method to decrease the running time of powermanageservice and main without rooting your device?
bump for the answer!
Anyone got it fixed?

There are many batter app that claims to be able to extend the battery life. Which one do you recommend? Has anybody tried "2 Battery" by Sam Lu. The developer claims that it could extend the battery life by at much as 1.7 times.

It depends on your own usage.
For instance, Greenify is a good once. It has a shortcut to force-stop all apps you add to its list. Which, for people who don't manually do so, can double battery life. If you're a bit OCD like me and do it manually already, it will matter very little.
Also, disabling as much bloatware as possible also helps tremendously.

I have to agree... greenify is great.. dont forget that not only does it stop it.. it prevents it (for the most part and most apps) from loading up again until you manually open it... that is the other benefit.. so stops those apps from causing wakelocks and draining your battery even more.. so by far one of my most recommended apps to have

DU Battery Saver in combination with Deep Sleep Battery Saver.
Buy full versions, set up Smart saver settings requiring root access.
Can't be beat.
Greenify too.
So, I checked my battery usage on my M8 and saw some apps like Facebook,Whatsapp are taking too much battery compared to other apps.
So my question is, How can I disable the apps without entering into settings>app.
Is there any widget that we can place on the homepage so that we can disable/enable apps whenever we want ?
Thanks

Greenify. It works for both rooted and nonrooted devices.
consider also xposed + amplify. for the same price I think there is more control about what is eating battery. you can disable or limit rate of strict wakelock/alarm/service. but it is not so simple as greenify and require some set-trial-repeat process.
but once set you have pretty much full working device with all connectivity goodness but with considerably lover battery leak.
for me it was like dropping from sane uncontrolled 50mA to 6-8mA per period during idle hours (when the phone screen is off). 1% drop per 2 hours. kk but different device - s3 lte.
btw. that's interesting if it could manage to last ~200h on single charge - workweek [emoji15] however I'm not at position to resist so long period without checking Parez Hilton rumors [emoji6]
Hey guys
I recently installed CM12 (official version) but i noticed that it eats up alot of battery alot quicker than my stock ROM
i installed better battery stats and started recording stuff but idk how to read the information it provides
can someone help me?
Thanks
You could also try a cpu app such as no frills cpu to set the min and max frequencies.
I don't want to mess with clocks till I have expended all my other options. Do you guys know how to use the information betterbattery stats record?

Set BBS to show stats since Unplugged.
Charge your device so that it is fully charged just before going to bed.
Unplug and let it set idle overnight. This will let you know about background processes consuming battery, as opposed to you actually using the phone and consuming battery.
First thing in the morning open BBS. Click the share icon at the top left of the screen. Select the Text Dumpfile option and then Save. You could then take screenshots of the BBS pages; especially Partial Wakelocks, Other, and Alarms.
There are active threads with participants who are very familiar with interpreting the BBS results obtained.

You could also try dkp kernel. Search the forums here. I've heard you can get better battery life with it on cm12.

I used to use Greenify when I had my Xperia Z3, but I don't know if I should keep it on my 5T, and if it affects performance or not (ex. reopening apps draining more battery or apps taking more time to open).
I have the 8 GB model, so I don't have any RAM problem.
Lately I've decided to try not using any battery "optimizer". I'm currently on OOS B2 with Flash Kernel 3.0..1 and I can easily get nearly two days if battery life with a "normal" use with around 4hrs of screen on time and 1~1.5% per hour while on idle overnight.
So, I think that overall that's not worth messing with Greenify. IMHO
About performances, in theory having to relaunch apps that have been terminated by Greenify would have some inpact on that. Guess that would be quite low, being the device so fast!
My advice would be see how it goes as it is and then try installing Greenify and see if you notice any improvement.
My two cents.
M!

Greenify only hibernate apps, not terminate.
I use Greenify for Facebook and Messenger as they drain a lot of power. I would simply check your battery stats if there are apps that use a lot of power without active usage. If so, Greenify then. If not, it probably doesn't make a huge difference.
Greenify is no matter what, a must download app for me.. Until V30+ and OP5T.. Didn't need it anymore, because I didn't notice a different between installed it and not..
This is an easy one. No.
Deep sleep and idle battery drain seem pretty good on the OP5T so far, I wouldn't bother.
I still use it, nothing related to performance but because I personally do not need some of my apps to run in background. I only use them when I open them so I can save a bit of battery by keeping them hibernated until the next use.

As long as I have good cell signal, I can routinely get 8hrs of SoT with the stock One plus kernel from OpenBeta2. I do use Greenify for the social media apps though. Greenify will basically tell you if it will help or not by displaying apps that it thinks will benefit from hibernating. Although, if you aren't rooted, it basically isn't worth installing.

I'm just asking because I use Amplify, Greenify and Android's built-in battery saver and Android OS still drains A LOT, and by a lot I mean that I can get 3 hours SoT with amoled themes on.

Wait, you get that on the 5T? If so, return it.

I reinstalled the whole rom, seems like its fixed now, I probably messed something up with the kernel.
