Poor battery life on beastmod ii 4.2?

I don't know but for some reason battery life has been horrible since I switched to beastmod yesterday it lasted only 6 hours and 45 minutes when the phone was on 3g. When I'm on wifi, I get around 19 hours. No offense to the developer (it is a great ROM) just curious as people on this forum have reported
excellent battery performance on this ROM.

Battery life for me was better then stock. With regular (periodic) use I would get around 23 hours, with heavy use around 12 hours. Could be the install or wipe the battery stats.

Let the battery do like 3 or 4 cycles..

My battery life is doing great. Give it time.

I'd recommend an app that helped me extend my battery life. "Traffic Monitor" by RadioOpt GmbH. I was able to identify apps that were eating up data and battery.

Whats the most you get from your battery from full charge? I am really impressed with battery performance of Note 2 with out any mod or custom rom its way better than my old S3 LTE version.

I have got so far 27 hours, with 3.5 hours of screen time, on LTE on about 80% of the time. This is on my first full charge on the battery. I did not use any power saver settings.

Fantastic battery life on 4.2

Battery life is very good compared to the previous releases. I ran for forty minutes with Bluetooth turned on while listening to tune in radio and using endomondo app. Google now turned on. I lost fifteen percent compared to losing 35% with similar usage. Very satisfied.
What do you think?

Why would you make a thread linking to a post you made in another thread?
Bit unnecessary. To answer the question it's too early for me to thoroughly test battery life.

thats not fantastic at all...

I would wait for at least 2 complete battery cycles to make a thread like this.

Ditto. My phone ran like a champ on a freshly flashed ROM. Then my phone realized it was born as a Verizon-Nexus mutt and had a psychological breakdown to the point of 1.75 hours of on-screen time the day after.
Twas a sad day

I'm reading my work email over the exchange service account. After upgrde to 4.2 the exchange service process eats my whole battery so I can't tell about any improvement.

When it comes to battery life (in general, though especially true with this newest release), it's crazy how many divergent opinions you get. Some people claim to get amazing battery life (exactly what quantifies for amazing?) and some people claim the battery life is crap. This is just to remind you that unless you have a good way of measuring battery life, your measurements can be plus/minus hour(s). Someone who just leaves their phone on a black screen with no wi-fi and cell may get 10 hours of screen-on time. Someone who is watching videos with cell/wi-fi might only get 2 hours of screen-on time.
In the future, I can make two recommendations:
Always report a complete cycle (from 100% to close to 0%). This is because the battery does not discharge at a constant rate.
Always report screen on time
Average for GNexus in previous builds was 2-4 hours. I've no idea about the plus/minus, but they tend not to be under 2 and over 4 with moderate usage. I think an average of 3-3.5 hours is what most people are happy to report.

And that is really sad because my old atrix used to get over 8 hours on Wi-Fi with over twelve hours of standby time. I wish they would make this phone but with a smaller screen size. The technology used on this phone is not battery efficient at all.

This tells us nothing....u don't show ur screen on time and uve been charging off and on..

Battery life in sleep mode is worse for me. I am losing 3% an hour with the screen off, I used to lose only 3% total overnight with the screen off not per hour. I tested this over the last 4 hours only waking the tablet up long enough to check the battery level and it has gone down by 3% each time. Nothing has changed with any apps or setting since I upgraded from 4.1.2 to 4.2. I got concerned when I noticed this morning that my battery was over 15% less then when I went to sleep. Anyone else notice this?

This is very good battery by my standards.

The screen on time is good but not much of an improvement. Also it appears you had WiFi off for most of the time.

[Q] Heavy battery drain on jellybro 4.2!!!?

Hey guys im new in this forum so hello to you all
I recognized a heavy battery drain the last days since i updated to jellybro 4.2
To be more precisely : i used my phone 2 hours display on simple surfing and lost 40 percent at 75% display power
Then i switched to cyanogen mod 10.1 and it was nearly the same switched to leankernel ...nothing
I also did a complet format of my storage and flashed the stock by the toolkit and still theres the same problem it s better now but nethertheless bad enough
So what do you think?? I dont know what to do ...
Thanks to you all

2hrs screen on time and you only lost 40% battery? seems fine to me.

Normal.
Beamed from my Grouper.

You are kidding me arent you ? On jellybean 4.1 i just lost around 10 -15 percent!

So you're claiming that on 4.1 you have 13-20 hours of screen on time at 75% brightness? Yeah, not buying that at all. Losing 40% for 2 hours of screen on time is pretty good, even for the 2000/2100 mAh battery.

Totally normal drain. I'm calling bs on the 10-15% in 2 hours with screen on.

Hmm yeah of course there were Not so impressive Times but IT feels To me like too much naah i will watch it a Bit a big thanks to all of you guys i liked to hear other opinions on that

I will switch to that and try. Is one of the few that i have not tried.
Sent from my Galaxy Nexus using xda premium

My average is 8hrs on battery and 2-3hrs screen on time with stock battery so I think yours is fine.

Finally i dropped to 0.2-3% per hour in flight mode using 007 kernel.
With almost all others were at 1.4% with same config.

Battery Life

I recently bought a GSM galaxy nexus (NTT DoCoMo version) and I use it on T-Mobile's prepaid network. The original battery that it came with was terrible.. Literally only lasted 7 hours regardless of screen on time. So I bought a stock Samsung battery off eBay thinking maybe it was a bad battery. No help whatsoever. I've flashed different ROMs, radios, and different kernels. Can anyone help me figure out what's going on? I had a Sprint Galaxy Nexus and I could get up to a day on the battery with 2.5 hours of screen on time so I know the Galaxy Nexus can last a long time. What's the deal?

Could you post some info on battery drain statistics from battery settings tab or preferably gsam monitor over a full drain? I could probably help you out, just need some more info. Also try flashing fancy kernel if you haven't already. This is a newer kernel that gives the best battery life you'll find freshly flashed.
Before discharging toget battery stats I would try charging to 100% and using "battery calibration" by NeMa to clean your phone's batterystats file and then drain to zero with a screen flashlight or running gallery slideshow. This can always be a problem no matter how healthy your battery is.

This is what I have showing for my battery so far. I flashed the newest radio last night and that seems to have helped a little bit with the battery. I have tried the battery calibration and it didn't really seem to help much.

I have flashed a stock 4.2.2 ROM a week or so ago and I was still having this issue. I bought a new battery too and its still happening. Flashed the fancy kernel today and it seems to be helping a lot actually.
Sent from my Galaxy Nexus using xda app-developers app

The stock kernel performs way better then what you are experiencing. A custom kernel may help a bit, but it's not magic. I'd recommend using the app BetterBatteryStats in order to find out what's going on.

Do any of you think that me restoring apps would have anything to do with the battery drain? I'm not seeing anything out of the ordinary in the GSAM battery stats but the battery drains way too quickly. 10% per hour even when I'm not using it..

Glad to hear that fancy kernel is helping. It's probably the closest thing to magic you'll find. I agree that 1 hour of screen time and under 12 hours is under par, but I was having these same issues 2 months ago and could not believe how crappy battery life was. It really got better though trying a bunch of different radios to find the right ones, using minimal gapps/resource hogging apps as possible, finding the right build.prop tweaks to use, and most helpful flashing some good reliable kernels like fancy and AK/anarkia that have incredibly useful customizations that stock just doesn't have, I.e., contrast and color settings, battery friendly governors and frequency profiles, optimized smart-reflex, and custom regulator voltages for display.

Well, didn't feel like it lasted too long. Fell asleep with my battery at 33%, woke up 3 hours later and it's dead. I'm ready to throw this phone out the window.

Battery App
I've tried to find a rom and kerneI that would help with battery too, nothing made that much of a difference though. I use the 2x battery saver app now. I get at least double the battery life sometimes more.

I see you got the app. Good. Now a few minutes isn't enough time to gather reliable stats. Review the results after a full drain cycle of the battery. Check partial wakelocks and alarms for suspicious activity.

Here's what was listed on BBS after a full drain. Do you see anything unusual? I turned my data on and kept it on 2G to prevent the no or unknown signal from eating more battery but that was the only change. Battery life still looks terrible.

No need for the snake oil app, as simply unplugging the phone after a full charge wipes battery stats. Wiping battery stats and draining to zero aren't going to have any bearing whatsoever on this issue and would needlessly shorten the battery's serviceable lifespan.

Whoops.. I forgot to screenshot those. I'll get those later today. So I put my phone in airplane mode to see if maybe it was the reception... Phone kept draining. I will try to wipe everything off the phone later and not install any apps and see if that helps.

According to these stats, it looks like Google talk and the calendar are my biggest wake locks? I disabled Google talk, turned off location history for Google maps last night, what should I do about the calendar? I feel like my phone is becoming useless because I have disabled so many things.
