Stock battery life survey

After using CM 10.1 for the last two weeks and loving every second of it (including the unbelievably impressive battery life), I regretfully had to return to a stock ROM to avoid outgoing call audio bugs that were interrupting my phone's use for my job.
Out of curiousity, what kind of battery life is the typical stock ROM user getting? On CM 10.1, I was getting almost 4 hours of screen on time with 40ish percent battery left by the end of the day. What can I expect with stock TW?
There's a thread somewhere in here that talks about battery life and I'm seeing most people get between 3 and 5 hours of screen on time. A few people have horrible stats at around 1 or 2 hours, a few get 6+, it just depends on what you have installed, sync etc, and how you use your phone. Personally I average 3 1/2 - 4 hours on the stock ROM with Gmail, Facebook, Instagram, and a few other small things syncing.
Im running stock rom rooted with awesome battery life 5+

[Q] 4.2.2-4.3 battery difference?

Before, while running 4.2.2, usually cm10, i had been getting just barely over 3 hours sot, so not bad, it was acceptable for me. Now, after flashing 4.3 roms, and the new bootloader, Im struggling to get even 2 hours sot, even with lighter than normal usage. After going to 4.3, if i flash back to 4.2.2 roms, I now still get the same awful battery life. Generally, to go along with the 2 & 3 hours sot, my total time off charger is between 8-10 hours off charger.
My question is does anyone else have the same big difference? Could it have been the new bootloader and any new firmware i may have flashed along with it?
With how i spend my day, (I play Junior Hockey), up about 8am, light texting, snapchat, Instagram, while connected to WiFi, then about the same usage until about 6pm, keeping light usage, i drain completely with 2 hours sot.
Try calibrating the battery, go to the play store and download an app called battery recalibration, follow the instructions in the app, and you should be good. I noticed a definite increase in battery life from 4.2.2-4.3 so, you should be fine.

Hello.
I noticed that on CM is battery drain faster than on stock LG rom. How is this possible if lg rom is bloated?
Has someone bettery battery life with aosp rom, or is LG always better?

It all comes down the the kernel for the most part, in this case, I have seen exceptional battery life with AICP - http://forum.xda-developers.com/showthread.php?t=2494700 -
It's been stellar, and has an unbelievable number of options. It has rebooted on me in a week all of twice, which is way acceptable in my book compared to the bloat and stuff that comes on the LG rom. I love the rom, tons of themes out there on the playstore for 10.2, etc.
I was wondering the same thing, if the battery was going to be better or worse on AOSP.
I've been debating what direction I was going to go with software on my phone AOSP or custom stock
So i tried CM M1 snapshot. Usage was same as with debloated stock LG rom. Sync on, wifi or internet on, some low brightness and some high brightness.
I think that even phone was used more with LG rom, for same period of time LG rom was at 78-80% and CM rom was at 69 %.
As you can see from screenshots, no wakelock on CM.
Second screen is display.
In my experience, lg rom giving me better battery life than cm.
I get 24 hours battery life with 5 hours SOT with LG rom, with cm I only get around 4 SOT

It s quite big difference. Hope that future roms and kernels will improve battery compare to stock.

Taking your battery to 69% after 18 hours with an hour screen on time is not an indication of anything other than great battery life for the first 18 HOURS!!
Then you DON'T post screen shots of the LG ROM and just say "I think" it was 10% higher and are upset?
At the rate you're going you'll be at 3 days with three hours screen on [email protected][email protected] - Now THAT was a scientific calculation!!

For awhile i thought CM was better, but running the 11/7 version, it seems to be draining faster than stock
I haven't been particularly happy with my battery drain running AOSP (Cyanogen mod nightly at the moment) which is a pity because other than that it runs great.
What I've been doing is charging my phone up to 100% before going to bed then leaving it idle (connected to wifi) while monitoring it with BBS.
What I've found is it's draining at around 3-6%/hour. The strange thing is BBS shows that my phone is going into deep sleep mode so why the battery drain, possibly powermanagerservice wakelocks?
...
I made second test. Tried to use CM and stock ROM in same way (browsing, fb, some videos, calls, mails) plus I greeniefied some apps and some system apps and with same screen time I have result 84% stock rom for 1:20 screen time and 70% for same screen time in CM M1 snapshot.
On both screen was mostly at 0%, sometimes about 30-40% .
Honestly, can´t find any explanation why CM drains more battery, every post or article just said that it was wakelock or that CM just drains more battery.

Wow. What´s your magic.

Very disappointed with the S4 Battery Life

I'm currently on deadly venom v 8.2 on mf3. I only get 2-3hrs screen time w this device. I already greenified all everything connected to Google like maps, services, search, etc. I hate the fact that you even have to do that just to maximize battery life. I don't like turning on and off stuffs like location services, blue tooth, and wifi. I always leave them on. I hate the fact that you need to lower the brightness or readjust the brightness again and again just to increase battery life. That's a no no! I have bad eyes, I use lux dash as my auto brightness. I don't have any background widgets on my phone. My home screen is just filled w apps (no widgets) because they say widgets eat battery. My phone can last the whole day when it's on idle. Battery is 3-4.5% per hour when on idle. It balloons to 15%—25% per hour once I start using it which is very annoying. These are the only apps I use and I always close them all the time. Instagram, Facebook, Twitter, viber, Google voice, BBM, Gmail. What can you guys suggest to improve battery life? I don't believe people saying that they last 2 days or even the whole day. That's complete BS. I'll attach a screen shot on from better batter stats when I started making this, I started from 100%
12% in 33mins. Geeeez

If you need a phone with good battery life you should of bought a note 3 or LG g2.

You might want to get a new battery... My phone is running Graviton and I have excellent battery life. I keep power saving mode on, use Greenify, turn off Wifi, GPS, and Mobile Data when NOT needed. Generally I push at least a day and a half out of this stock battery before doing a complete charge. I try my best to not let the battery drain 100%.

If it went from 100 to 12% in 33 minutes you have a bad battery, plain and simple.

Right. Bad battery is very likely. That and should be using better battery stats to get a picture of what's going on.
It's not the phone and naming the ROM as if that has something to do with it is bad form.

What he said. I am stock but rooted and using Juice Defender, Greenify, toggling gps and mobile data off etc, I get full day on high usage and 28 hours on light usage. Must be a bad battery.
Meh, did some math. 12% in 33 min did cross-multiplication for 99% battery used, got 272.25 minuets divided by 60 to get an hourly total. You'll be getting 4.5 hours on screen time.
I don't personally think that's bad. Did some more calculations for Nexus 5 on battery. Heard it's getting about 3.5 hours screen on time, so with that to get your 4.5 hours screen on time the nexus 5 would need about a 2960mah battery.
Well, firstly, you should believe that some people's last 2 days or so; as I've seen photos posted by "battery life enthusiasts" in the better-battery-stats thread and other places showing it's possible. 12% in 33 minutes isn't that bad and is around a stock TW battery expectancy.
You're on MF3.. which means you cannot run an AOSP rom, so almost anything your running isn't going to be extremely lightweight for battery. ALL TW based roms will drain battery more than a single AOSP or GPE rom, as the system is a lot more heavy.
I greenify anything associated with the google-cloud or push-notifications, if I want to know my Facebook updates I can click on the app myself. I have location services turned off because there's ZERO reasons to use it unless I have a need for my GPS. Do you know that MANY apps use your location service even when not running and cause constant wake-locks. I've also moved my Google Services Framework from a system app to a user app with Titanium Backup Pro so I can greenify it and completely disconnect myself from Google if I have no needs for the play store or push-notifications. Gmail and gmaps can still run independently fine without the Framework, the GSF is also a major cause of wake-lock battery drain. Even if you greenify google apps, the GSF is still going to cause numerous wake-locks and affect battery.
I don't have a photo at the moment, since my phone is plugged in all the time anyway (just to keep it topped off), but I've had it run for almost 2 days without charging it; with occasional screen time, gaming, and having it idle. I'm also on a non-TW AOKP rom that's very very lightweight.

Here is my battery so far. As you can see, it barely has been used since yesterday. Screen on time is 25 minutes. Wifi is always on and I weather widget reloads every 4 hours. GPS is off though. Obviously, it lasts slightly less than a day if I use extensively with games, web browsing, email. Considering how much I usually use the phone, it does last 2 days.
Im on MF3 and using Wicked rom with SS.
If you get a new battery....
If you are thinking about getting a new battery and don't mind the extra bulk, go for the 7500mAh Zero Lemon Battery. I got one over a month ago and it will EASILY get 3+ days of battery life. It will add a lot of mass to the phone, but if you are looking for stupid battery life, check it out. Right now I have 26 minutes of screen time and 92% battery life left. It's been off charger for over 8 hours.

Edit: Forgot to mention I'm Full Stock / Full Lock.
I have noticed the standby battery on this phone is AMAZING!... but the screen on time is horrible for me too :S... can barely get 3 hours and that is with like 30% brightness... sigh
people said amoled helps save battery... but i used to have muchhh better battery with my htc one
So these are my stats on very light usage. Very good idle time. Just 2.5 hrs screen time

[Q] Lollipop battery life stats

Hi all,
Just wondering what the battery life is like for all you Lollipop users. I feel like the battery is around the same compared to when I was still using Kitkat.
I currently have 8 hours of screen on time with about 16% of battery left. I'm using AryaMod build March 16th 2015. No custom kernels.
Power mode setting is enabled, I don't listen to music, no GPS, no web browsing, but occasionally I do watch a few Youtube videos. I also use a lot of Memedroid and some textings with Line.
No Xposed installed (don't want to mess with it until it's stable for Lollipop) but I do use Greenify.
Anyway, most people might think 8 hours of SOT is a lot with 16% battery left. But if I look at BBS, the stats are rather disappointing. There are a lot of Google Play Services wakelocks (even though Google Play Services is already Greenified). I also see a lot of PowerManageService.Wakelocks under Kernel Wakelock. I've done the best I could to troubleshoot this but it seems like there's not much else I can do to optimize it.
Just wondering what battery life you guys are getting?
no one?
I justupgraded yrster to 5.0 on my note 3 and it is draining a lot fater. If there was a root i would get rid of the stock aps that run in the backround. I would say it could use a partial charge around 4pm if i take it off the charger at 630am
