I find battery life on my zenfone 2 laser is quite good but then it has a snapdragon processor not an Intel. I think that's the problem.

the problem is software related i recon

I had the battery drain issue pretty badly until I rooted my device and installed Root Booster.
I choose under extreme modes: Battery Boost in which you must pay 1.50 for but I find it too be well worth it as it manages to reduce the battery drain by quite a bit.
A good example is during the night I always lose 7% battery even with everything off and I only lose 2% during the night and around 3% during the day ^^
I usually have between 12-14% extra battery left over before my usual daily recharge so I'm extremely happy with this program ^^
Give it a try!

[Q] SGW I8150 drain battery very very fast after i flashed it with CM-10.1 alpha6

i just flashed my samsung galaxy wonder to have CM-10.1 alpha6 a few days ago. and i realised that it drain battery very fast.. just simply fully charge it to 100% and left there with wifi,bluetooth and all applications off, yet the battery drained in half day..
if open 3G, the battery drain 30% in 20 minutes.
can sumeone tell me what's the problem and how can i solve it? thx a lots
Why don't you try to flash another kernel..
I personally recommend kernel by hurtsky, or by castagnaIT.
that's only my opinion..
you're welcome to try..

first, how old is your battery?
older than 1 yr, u should try getting a new battery.
mine was 1.4 yr old, battery drain when play game lasted 5 mins from fully charge to zero.

Well..
It's just the same way like how you flashed the cm10.1 rom..
Try to head to this page:
http://forum.xda-developers.com/showthread.php?t=2218087
There's also an instruction on a proper way to flash it..
And don't forget to thanks him if you like his kernel
CM10.1 aka Android 4.2.2 uses higher voltage compared to CM10 and CM9(especially CM9).
So its understandable. But in CM10.1, SGW can use 1.0Ghz and still fluently do a lot of things.
Try underclocking and undervolting.

try to consider the age of your battery, your lcd revision , and usage.

agree..alpha 6 still not in revert kernel..maybe your lcd is the main cause drain your battery..

I have CM 10.2 everythings is ok..battery consumption is depends from life time of your battery then the number of apps and services activated...
Change to new battery
hmmm.... maybe it's because of your battery.. from my experience , you should buy new battery if the battery is used more than 1 year... i had experinced before when my battery drain faster, after i bought new battery.. the problem solved...
Guys. Stop telling him it´s the battery. If it were the battery the draining would be already that fast before flashing CM10.1, but not just after.
A bloated and aged battery can of course be the reason, but this doesn´t have to be always the case. My stock Samsung battery is already 2 years old but working like new. However I have to admit that I don´t use it that often. Having here 3 batteries I´m changing them regulary every few months.
This draining will be more related to the LCD version in his phone, which he should read about and check before flashing a CM10.1 based rom. Additionally the recent Google updates can cause even more battery drain than the LCD Rev.3 issue alone, which has to be taken also into account.

Samsung galaxy S4 mini battery drain!

Hi everybody...I have this phone and I have a problem.When I charge the phone up to 100% battery and then take it from the charger,battery drops to 99 or less without phone usage...And when I go to sleep and then wake up,the phone lost about 10-15 percent...Can somebody plesase help me?
Check what's keeping your phone awake during idle, "wakelock detector" and "better battery stats". Though you need root for these. You've nor given us any details of what your phone is and what ROM?? Try searching for threads on how to calibrate your phone battery.
Ohh sorry...My phone is S4 mini GT-I9195 LTE....I have stock android 4.4.2 kitkat...I have already calibrated battery and bought new battery...But same problem...
Will be an app causing your phone to wake
I dont know...i searched on the web and someone said that stock kernel have some problems

Not always the case... Depends when and where your phone was made. Could be a faulty kernel or motherboard but it also could be an app or a setting on your phone or an unclean install. Have you always suffered this issue?
I got phone about 3 weeks ago...and the battery was very bad so i bought new one.I also tried CM 12.1 but the phone is heating in unnormal way but the battery there is better...
You have problems with motherboard. Go to service center to replace it on waranty.
Powered by CM12.1
But my phone isnt on waranty...i got it used haha....ahh nvm,i will live with that problem.thanks for help!
Bad luck then. Normal consumption for our device is 0.2 - 0.3 % per hour in stand by.
Powered by CM12.1
How long does yours battery last with some normal usage?
Almost 3 days with moderate usage.
Powered by CM12.1
Woww thats a very big difference haha.

Your best bet seeing as unless you pay for a new motherboard is to try one of the battery drain fix kernels on here. Though I think you may be limited to certain compatible ROMs.
Why are you not staying on cm 12.1? For me it's amazing, i observed at least 100% more battery efficiency than stock (4.2.2). I also observed the same problem with high temp too. But i think we can't have it all. When i play games and the outside temperature is about 35 celsius, i do not expect anything less, because this mobile is not designed for this android version. I think that's reasonable and i finally can use my mobile with a joyful way without having my mind always on the battery stats!

Thanks guys! And i will try CM 12.1 for longer time to see if anything will be better!

What is the truth about the Android OS battery drain?

First, sorry for my bad English.
Everyone using ZF2 knows about what I'm talking about here: if you look at the battery graph in the settings, Android OS is probably responsible for most of the battery usage. :silly:
At first I was horrified about that, but then I realized something was off, something that I notice everyone is ignoring: Android OS drain is too high. I mean for me it's always 5 to 8 times higher than the second that is the Screen. The reality is that I can still have 4 to 4.30 hours of screen-on time, 3% drain for 7 hours of stand-by at night. So just think about it logically, what if we can make the Android OS work "normally", which is that Screen will be on top of the list and Android OS somewhere below, then how long my screen on time will be? You know what I mean? We are getting rid of a drain that is 5 times higher than Screen on the list! Does it mean our Screen on time will now be 20 hours???
So, I came to a conclusion that this issue may be in fact an error in the data. Maybe nothing was wrong but the Zenfone 2 team messed up the calculation for the battery usage and ended up showing a ridiculous result. what do you think about this?

wow that's crazy, how is that possible for you do you think? :angel:
I'm using stock, disable most of the bloatwares but I'm keeping all Asus important ones such as power saver (I always set it normal however), start manager (disable all except OTTs and sms ... you know why).
Does that mean I'm partly right? If Android OS truely eats up so much battery power, how can we achieve such low drain during stand-by time? It's not logical :silly:

i use Extreme v2 script.
i disable all app in auto-start manager
power-saver is normal mode.
i go to sleep 9pm ---> 6am. my phone just get 1% ^^
u can try this.
p/s: my phone ZE550ml. maybe your ZE551ml with 4GB ram , cpu 2.3GHz could eat battery life more than mine ^^

thanks for the link. However I don't want to root my phone, I just bought it a few weeks ago and I will keep it intact until I get Marshmallow, I used to be addicted to Rom Flashing and it nearly killed me haha. I can use the lists for reference, anyway.
Yes my phone is 551ML 4GB ram, probably that's why I have higher drain when stand-by. Because I have lots of experience with Rom modding I believe I'm not missing anything with my current settings.
Ps: your English is fine, don't worry :fingers-crossed: judging at your username I bet one penny that you're from the same country as me
how many times its been said..zenfone 2 stand by time is superb ...its when its use the drainage is fast..why fast because of incompatibility of zenfone 2 screen( cheap screen ?) and intels hardward... ...so no matter how you adjust it will never be a 2 days single charged phone. anyway ive had a nice experience with my zenfone 2 ..gave it to my brother and bought nexus 6...wanted to have 6 inch phone anyway....

i think so. bạn ở đâu ?? mình hcm kakaka
The main responsable in battery drains is usually not Android OS, but Google Play Services that screws everything
This issue has already been discussed to death all over the place in different forums. There are many reasons why the battery life is not good on ZF2 some of which are what you pointed out. The main problem is with 5.0 itself, this was and is a known problem, no amount of "tweaking" is going to fix a problem with the OS itself. This is why many people wanted the 5.1 update to no avail from Asus. Did it fix all the problems? No, it did not but it did stop a lot of the battery drain.

I agree that 5.0 is not optimized and it's not the best, but people are talking like Android OS is a crimminal, I think that Android OS is just taking a bit of battery, but definitely not 5 times higer than the screen as explained above like instead of 5% of battery it is consuming 10%, it's not good, but not a disaster either :silly:

it might be, I used to greenify Google Play Services, but on some phone it will lead to a lot of force closes. Supposed it's the cause, it also can't be 5 times higher then the screen, or else our phone won't be able to maintain >4 hours of SOT, isn't it? :silly:
No, 5.0 is and was a disaster. It had so many bugs it should have never been released
That is for sure...

which rom for oneplus 3 has best battery life and performance

Please tell me which rom is overall gud for oneplus 3. Checking all the rom ia not possible for me it takes lot of time and i m really disappointed form oxygen os 4.0.3 it drain lots of battery please suggest me a rom with good battery life and performance i dont care much about customization
Iam afraid there is really nothing that can help you (or others like me..). I have tried allot of ROMS and they all result in somewhat the same result.
1 charge 1 day (or almost 1 day) Does not matter if i use custom kernel battery improvement tools or "special" tips and tricks at the end of the afternoon iam still running low. I know i use my phone ALLOT and i use allot of connectivity (WIFI, 3/4G, BT) that is properly the issue, but still its sad that the only thing that might help is buying the oneplus3T.

If you want to stick to MM then go for Sultan's CM & if you want to upgrade to N then go for Resurrection Remix. Both ROM's stock kernels have new good battery life but in the camera part they are out numbered. Sultanxda has done best job by optimising the inbuilt camera app at par with stock OOS & also he gives security patch updates too as soon as they are released.
Resurrection Remix on other hand works great with Android N but has buggy camera due to buggy camera on LOS & we know that till now OnePlus has not released blobs so can't do anything.
All this is my personal preference. You can try out both our any other ROM's from development section like Cypheros or AOSP extended which are AOSP & LOS based or for for Freedom OS or Experience ROM which are OOS based.
I have around 7h SOT with latest freedomOS and bluspark kernel. In my eyes thats pretty good and carries me easily through the day. And light use even 2 days.
If you have any heavy battery drain you should search for the reason. Check wakelocks and logcat too find out whats wrong.

Try VertexOS.. You wont feel a stutter and I'm not joking.. Als it scales way more efficient because of EAS. It delivers a near stock experience

Well it has EAS.. Which means that the CPU can be really tamed.. Battery depends on standby but in my usage pattern I can easily get 4 hours SOT. I get an average drain of 13% per hour.

Bluetooth battery drain

Before flashing a custom rom i had no problems with my p2 at all. Last week I installed the lineage 14.1 rom and now suddenly the bluetooth function drains my battery a crazy amount. It can go up to 88% of the total battery usage, i think on the stock rom it was about 5 or 10%. I searched everywhere but couldn't find a fix for me. Any help?

Do u actually notice a battery drain...what is the SOT u get as compared to stock ROM
Sometimes it is a bug n shows wrong statistics

I don't know the sot exactly. But it has been a big difference since then. I used to charge my phone every 3 days and now i have to charge it almost every day. It has become a pretty big inconvenience for me
