[Official] battery stats thread

Once we get charged up (and back down), let's see how the battery life in the S4 compares to the quad core.
Please make sure to include your screen on time, as that is the best indicator of light/heavy use.

pleasantly surprised
I can't believe how good the battery has been so far, 84% after 13hours (over night)
I am a light user. still - that is impressive for stock. I never got close to that with my OG Epic on stock which was usually 3% per hour.

1h, 3M Battery down to 76%.
screen on for 38 min, 33% of battery usage.

Heres mine on a first day full charge...

Not too bad for first day with moderate to heavy use!

This is heavy usage. Screen on time of 3.5 hours. Downloading Max Payne and a lot of apps. Downloading and listening to audio on Google chrome. Lots of Pulse usage. Games, YouTube, and 30 minutes of phone calls.
*edit* Bluetooth and wifi on all day long.

More information is better for those of us living vicariously through you guys. Remember to include screen-on time. Thanks!

Here's mine for the first full day. Should my cell idle be taking up that much of the battery?
Sent from my SPH-L710 using Tapatalk 2

one thing im NOT noticing here is Allshare Service taking up a high percentage in your guys battery stats...
on mine its been at 7-9% and i dont know why, i have something waking up my phone when the screen is off and it might be that... ive forced stop, but i check later and its active again, ive disabled the service and the Allshare play in the application manager but still comes back on... hmmm i think im gonna have to root and just get rid of that file, or freeze it or something

Question... Does having all the motion settings on effect the battery? Also does having the NFC and sbeam on hurt the battery?

in addition, the eye tracker thingy?

This is only the 2nd cycle. Going to wipe stats after this charge

I'm still waiting for the second cycle to finish I have the motion controls on and the eye thing and I had no drop at all overnight

I wish I could get some stats like that. The screenshots are while I was sleeping and 7% seems like a lot of drain for it just sitting there. Only thing on was wifi. Cell standby time on is always the same as the time on battery, is that normal?
edit: the phone now shows 79% battery left with time on battery of 12h 46m; cell standby the exact same; screen on at 9% with time on of 48m. I'm fully stock and running power save mode.

Here are my stats. I think the battery life isn't too bad so far but we will see.

are the battery stats suppose to reset when you restart the phone? For dinner reason my persist even after a reboot

No, they will carry over until you re-charge or change the battery.
I was going to make a thread like this, but it was already here! Here are my results after my second full charge and regular usage. The results are on par with my fully modified and decked out Epic. Of course, this device has a bigger battery, but it also has a larger screen. Between the hardware and software upgrades, I'm very impressed with the stock battery life. This includes wifi on at all times as well as signal w/data. Some motion features are enabled, nfc is not, and google sync is off (I use stock email). Now how much further can this be improved?? Remember not to be discouraged, Screen On times will vary depending on what the phone is used for. Showing pictures is much less battery intensive than watching YouTube videos.

Really bad battery life

My device has been completely stock running ART kitkat.
Battery life has been really bad the last few weeks. (Possibly due to 4.4.4?)
I have switched off location services, Google now, and only sync gmail.
I can only squeeze out around 2 hours and 30 minutes max compared to 4 hours 30 I was able to before. (Same settings, flight mode WiFi only)
Any one have any advice please? How can I monitor and see what's draining? I've tried a a few apps but I can't find anything.
Thank you.

None taken.
I may be a recognised contributor, however in the last 18 months I've lost my interest in mobile technology, and hence I have little knowledge on mobile tech today.
I consider myself a "normal user" now. I just use my phone as it is as a regular user completely stock and I don't know these tech things anymore.
Any help is appreciated, any other info I can give? I'm rather incline not to factory reset my phone.

App sucker screen if this helps?
So daily mail is the cause?

It is the usage that drains your battery life. If fact daily mail online doesnt drain so much. I dont know, how much and how often you use your phone and that is what really matters.
What really drains batterie (and most people dont know this) is waking up your device often. When you wake up your device all cores goes to max frequency before turning down slowly. By 4 cores it drains a lot of energy. The second is the screen brightness. The brighter the screen, the more it drains. An than there are many other factors like signal strength and quality, apps...
So to sum it up, it is your usage behavior that influence your battery life. To compare I am on cm11 with matr1x kernel, do alot of surfing, chatting, listening to music and the average screen on time is 4 hours. You may try it out.

Thanks mate, appreciated.
I forgot to post my brightness.
I usually have my phone on flight mode at home and WiFi signal a minimum of 3 bars. (Excuse the screenshot which is an exception)
I suppose with my phone I do always switch it on and off multiple times, however I haven't had this battery drainage problem in the past, it only occurred in the last few weeks and I have the same usage pattern. I suspect it was the 4.4.3/4.4.4 update because prior to that battery was fine.
Thanks for the suggestion of the ROM, however I'm planning to keep my device stock and I still haven't factory reseted it since day 1 (August 2013) and hope I do not need to.
Thanks all the same.
Open to more suggestions many thanks to everyone.

Install Greenify and hibernate Daily Mail Online. It's the one draining your battery I guess.
Greenify works without root, but if I remember correctly you need to hibernate apps manually.

Help with Battery Life/Power Issues

Hey all
I've been having massive issues with my battery life recently, it's never been great however it's actually gotten a lot worse post Kit Kat. I've taken a few screenshots on a few different apps like GSam Monitor, Wakelock detector and Battery Widget, I was wondering if somebody could help me diagnose the issue. Or at least just give me general insights into the numbers that I'm getting in terms of battery life.
EDIT: Just noticed a new issue where a couple of times my battery was somewhere in the 40's and then the phone crashes and when I start it back again it just has about 2 % battery left. Weirdly enough, after charging it for a couple of minutes, that battery now goes up to 30%. Would love to know if somebody has had a similar issue and what might be a way to go about trying to find some sort of solution.

1. If the screen is jittering and phone crashes... Battery is bad..
2. Try flashing stock firmware... Might be a software issue
Sent from my Nexus 4 using XDA Free mobile app

same battery issue here. Its not because software. i tryed CM11m11, Ubuntu Touch, stock.. same problem. Im waitting new battery, because i was not that gentle with batteru when i was repalcing camera 15 days ago.
Usualy moment before phone restart, lose sim signal, then freeze and restart

If flashing stock doesn't resolve it, I'd say the battery is dying. I went from 2 hours between charges to 12-14 with a new battery.

I installed stock rom by tutorial what i found here, but problem stay same. Waiting for new battery

My battery is also dying (switched to new phone now). It averages about 1 hour of SOT over several days and it's only wifi only. I guess I could swap out a fresh one but it goes to show that we need easily removable batteries but they just don't last that long.

Experienced the same issues like you did. A friend of mine who is used to fix iPhones did it for me. I just bought the new battery and paid him a beer

Did your battery life return to "normal"? Not that the Nexus 4 ever had great usage time. I might attempt it myself as a challenge.

It did. I've connected my LG G Watch to my N4 so Bluetooth, GPS and mobile data are always on.
But Facebook is a Batterykiller I'm working from 07:45am till 4pm and when I come home I've around 40%-50% battery left.

Intriguing, but what is your SoT?

Around 3-4 hours when my Bluetooth, mobile data(3G) and gps is on. But I can't tell it exactly cause I'm not using it that much anymore cause my primary phone is the N5.

I replace battery, now everithing works perfect. It was battery problem, not software.

Crazy wakelocks: please help

I'm noticing some incredibly high kernel wakelocks on my Note 4, which aren't present on my Note 2 (which rules out something on my network causing the problem ).
It's anyone having these? Any idea how the heck I'm suppose to get these lower? Wlan_wake in particular is firing off several dozen wakelocks per second.

get an app called Amplify, aka LiOn Tamer, aka as far as i know dev could be changing the name of the app again as we speak. The regular version is usually good enough, although the donate version takes care of most of the other wakelocks...assuming you are rooted and have xposed installed, if not, good luck.
This app is probably one of the best apps to control wakelocks, the battery life increase is also considerable.
As of now I got 4h34 screen on time in 19h47 of battery life and have 37% left. I'm pretty sure if I wasn't working tomorrow and needed a full charge in the morning I could hit 6.5h of screen on time and an extra 7h battery life before I reach 0%. Stats that are not possible without this app

I've got Amplify, but it's not showing any wakelocks that would be close to those listed (in # of triggers). I am experimenting with a completely isolated wifi AP - so there's no way that devices on my network are pinging my phone. So far, wlan_wake and KeyEvents are still highish ,but there are some strange ones named "Event"followed by a number DASH number... I have no clue what the hell those are

dont disable it, just make sure you update the app list on it. I also got a N4 on launch day and the update was there out of the box, i dont have such issues though. I'm pretty sure an app is causing this, just gotta know which one. It could be almost any app, check your per app battery usage and see if an app is draining abnormally your battery.
You haven't mentioned this anywhere, but is this affecting battery life?

Could 7.1.1 battery drain be from apps not optimized

Optimize all apps on 7.1.1system apps is there a fast multi select way
Noticed upon boot never does it and after looking into battery history telling me to do this but setting's menu under apps don't have a method . By the way this is on pure nexus ROM.
7.1.1 seems to drain the life fast and my device is new 3/days old
Sent from my Nexus 6P using XDA-Developers Legacy app

Pure Nexus isn't great for battery life compared with other ROMs I've been on. Android doesn't allow some apps to be optimized. If your battery life seriously concerns you then you might want to try an app like Naptime which puts your phone into deep doze as soon as the screen goes off. You could also download a kernel manager if you don't have one and see if you are using a performance oriented governor or something more battery friendly.

I took phone off charger at 8:49am by 25min later it persists to drain in 2% increment drops showing 5 hours left before 0% that's insane .
Not the 6p I remember when I had it once before the day it came out .

If your phone truly is brand new, you're going to need to wait longer than 3 days to achieve optimal battery life. What is the date of manufacture in recovery>>barcodes? There are a few good apps that will tell you definitively what is draining your battery. BBS and GSam are two. It is also a great time to install Accubattery and get a benchmark on your current battery capacity vs. design.

The problem is not with stock Android 7.1.1. It could be your battery is defective or degraded. That's why I asked if your phone really is "brand new" or refurbished, and what the date of manufacture is. Install Accubattery and use it to calculate your battery's capacity vs. design.

Last few months my battery is also getting worse. Accubattery says capacity is around 2000mAh right now. I did often charge my battery, even when it wasn't below 50%. Maybe that killed it.

Not your fault mate, regardless of how you charged it. Battery was defective. Get an RMA if you can through Google or Huawei (even if it is out of warranty). If not, there are a few places selling good replacement batteries. Install yourself if you can, or take it somewhere to have the battery swapped out. Good luck to you.
