Abnormal battery life on stock 4.0.2?

Lately, I noticed my battery has been dying much faster than normal. I got the phone maybe like 3 weeks ago, and it was lasting longer. I'm not sure if it's some app I downloaded or just the bad radios in 4.0.2 causing me to keep searching for signal, but it's definitely impacted how much I use my phone.
Anyone know what's going on? Or if theres some known issue with this?
Attached are some pictures of the running applications and the battery charts.

8.5hrs with 31% is pretty good to me.
You should look at my battery, 5hrs down to 16% (I have all active sync disabled, turned of 4G AND screen brightness only at like 5% for the entire time.)
*sigh*

If you look that is almost all standby time, which should be lasting way longer.

That's not horrible but you should look into what's waking up your phone so often.
Whats your screen-on time there? It looks like its really low.

It was at about 25 minutes of screen-on, but the keep-awake on the android OS was an hour. Could this be the culprit?

Well look at your "awake" bar. Something is consistently waking the phone. Just syncing email etc wouldn't keep it awake that long. Its another app.
Use something like "BetterBatteryStats" to monitor microscopically whats waking the device.

Thanks, I'll use that app and post results.
Another thing is I looked at the cell standby, and it told me that 25% of the time it did not have signal. Could searching for signal cause the intense battery usage?

yes, absolutely
90% of battery problems are either user installed app or radio related so far on the nexus thread

Looks like you had some times of bad signal based on your screenshots, but not the entire time.
Bottom line your phone should be idling much better than that. Granted I'm on GSM and not LTE, but when I turn off my screen and let it idle (i.e. forget to plug it in over night) the graph is almost flat. It will idle forever. Yours is not seeming to do that.

reboot..
I reboot my phone twice a week. It works really good.
Battery after a reboot and 9 hours standby. 96%
Without a reboot 70%
Big difference..

After much testing, I found out the anti-theft feature in Avast! is causing the massive battery drain. It prevents the phone from going to sleep.

Ow that sucks well out with that app, I use avg very good. Also I get an average battery usage of 3hours screen on time.
That's with most syncs on also wifi and GPS are always on.
Usually its bad apps that can't handle ics

I'm also using Avast but I think my awake pattern fairly falls in line with the screen on pattern. Twice out of the 2 months I've owned my nexus the battery has drained really fast - normally I will get about 28 hours. Any ideas?

I dont get it.. I got the phone 3 days ago, but if Im lucky, the phone lasts for maybe 6-7 hours?
It gets extremely hot when used in couple of minutes, and its like the battery is drained by something hidden.
On a night it loses about 6-7% in 6-8 hours of standby with data etc turned off
I have turned push, sync, NFC, smart screen and all that "smart" stuff off.. so I have no idea bout what drains the battery. Even the screen is on 50% and auto -_-
I have the korean version (I think?) the european version - bought in Denmaek, stock. Not rooted or anything - but is it possible to root the EU/KR edition or is it only for the Canada/Sprint edition?

Same for me. Hes obviously not using hes phone much and not on LTE.
The battery life of G on LTE is really terrible.
By the way mo on arent hot last days, probably they fixed it.
Web via LTE eats like 15%-20% per hour, reading a book on small bright is 3%-4% per hour

Is there any way to tunr of LTE/4G then? I'd rather have good battery and like 20mbit than a few hours battery and 45-50mbit download speed .. :laugh:

Battery life is consistently around 11.5-13 hrs with moderate to heavy usage.

My battery is crap too sometimes is ok ..
but it is just screen what drains .. and + if u browsing internet and u have flash enabled it is big drainer added .. needs more cpu power..
if u put mobile on eco mode turn down screen to 25%-30% turn all radios off u should be fine
download apps like battery calibration . or battery stats or juice defender

I'm really not an expert at this. I have also just opened my Optimus G, so I can't share my personal experience with this phone. However, the battery of my Lumia 920 needed around a week to function properly. The first three days I got heating and drain, almost 10% per hour, but now the phone lasts easily for two days with light usage. I was looking everywhere on different forums for hidden factors draining the battery, until I found a comment, where someone described this phenomenon: he said that a battery needs around 12 full cycles of drain and full recharge before optimal performance can be obtained. So from now on I will be more patient.
Then again, I'm new here, so other opinions are welcome.

eeemm that is not true i had phones over years and batt been always same..
it is all about usage ..
jut do test charge it fully and dont do nothing with it just ocasional phone calls and sms's and ull see then..

For me on jb v03 I get around 18-19 hours with around 3 hours screen time, but agree its all about usage.
I mean if you leave your phone off most of the day with your wifi and data turned off it will drain very slowly..
I find the biggest drain is always screen, cellular connection especially when you have poor signal, and wakelocks.

I had same xperience with my iPhone 5 so I hope its the same with my LG.
But for know I've installed JuiceDefender and disabled LTE (HSDAP+ i fast enough for my needs on the phone anyway)

exactly this is my problem ..
we traveling to the places while am in work and there are areas where is poor signal or no signal that means phone automaticaly boost its signal which is very big drain and if your mobile has no signal at all and u obviously set to automatic search it searching searching and draining hell lot!

when 4g will be standard the manufs will have to make new generation of batteries to stay last longer o LTE..

Phone idle refers to the amount of battery cell radios are using up when the phone is sleeping. I would recommend moving to an area with better reception and disabling data when unneeded.

Data is disabled (and wifi).

battery life is fantastic, i get roughly 5 hours on screen time, when i finish work i have 70 - 80% battery with 1.5 hours screen time

My battery life on CM.
Disappointed kinda, expected great improvement compared to stock rom

After few weeks of heavy usage, I am noticing the battery performance to improve considerably, I'm running stock 4.1.2. V10D

Good news For G Battery(internal)

Hi To All I found This Battery For Our Belloved G.
The Good News is That The Battery Is internal.So Get some Looks At This:http://www.aliexpress.com/item/free...OR-LG-E960-E975-brand-battery/1303639873.html

Bigger capacity doesn't always mean better performance and battery life. I've read many opinions that custom batteries are in 99% of cases are worse than original even if they have 500 or more Mah than stock. So it would be great if someone shares his opinion about this model but I don't think anyone will want mess with opening phone etc.

Believe me or not, You'll never find a battery better that LG original one. LG 800 charge cycle itself makes a big difference.

as you wish. But I suggest you to do a factory reset and with a bit of simple settings you can have a battery as great as mine. I've had calls, text messages, wireless connection, taking about 50 photos in a party, sending over 100 megabytes via bluetooth, calculator and... with 63% of screen brightness. Eco mode was first off for a day and on after.

well, gaming and watching videos can easily drain the battery. This is true about every phone. considering the hardware, LGOG benefits from a OK battery. With similar specifications, Xperia ZR has a 2300 mah which doesn't make that much difference although it has a 0.1.5 inch smaller screen.

Yeah I would also like to have a better battery in this phone, I'm regularly killing the battery at the end of the day even though I charge it every night. Granted I work in a bad reception area which cranks up my radio and drains the battery, but still I think it should last the day...
If there is a third party battery that last longer I would love to know about it.

There can be but the one introduced here in the OP is not of high quality and may be dangerous for the device. Besides, it may not provide a better battery life. The best you could do is to request the mugen team to provide an alternative battery fo LGOG. They're really expert in their job.

Battery life not very impressive

How is the batter life for you guys? . I seem to be losing 60% in 6 hours with 30 mins Google navigation and some texting and browsing.

This is what I've been getting for battery life on my Verizon Samsung Galaxy Note 7. I've cut the bloat apps I don't want, almost all of my data connection was on wifi, web browsing, sending and checking emails, no gaming, had to turn it off twice (applying and reapplying a screen protector), used Bluetooth once for about an hour listening to music in the car, made a few calls and received a few calls. I turned battery saver on right around 85% battery life from 100%. The battery saver was custom and I left the screen resolution at 2k just only enabled limit performance and max brightness to 90%. Just over 9 hrs screen on time works for me.

Yeah mine hasn't been great. Think I'm gonna run it until Wednesday and if it's still not good I'm returning it and going back to my s7e in the meantime.

Mine has been doing very well, better than my note 4 did by a good percentage. The other day I tried to use Google maps for navigation but I was apparently in a dead area. Later that night I was checking battery stats and I saw that maps used 11% for a matter of minutes while the next non-system app was like 3%. There might be something wrong with the app on note 7 then maybe.

Mine has been really good. Usually when I leave work I'm at around 40% (on my S6 edge). Today I'm at 79% (on the Note 7).

So far, my best has been down to 14% in almost 16 hours, with about 5 hours of SoT.

Seriously, if you are getting 9 hours of screen on time, you have to have disabled so much of the functionality of the phone that I don't know why you would buy a Note. With every reviewer and average person getting 4.5-5.5 hours SOT, it just seems ridiculous..

I think it's satisfactory.
I find myself actually using it a lot more than the S7E AND the battery is better to boot.
Personally, if I couldn't use the Note 7 any more, I'd go back to using my iphone 6S+ before I'd use the S7E...
Or the Note 5 / 6S+.
From ergonomics, the S7E is just awful. It reminds me of using a Windows 8 PC for the first time! Mainly because of the horrible, horrible touch sensitivity of the screen and edge.
Perhaps the battery life is better because I've never charged wirelessly? I've heard that if you charge with the cord your battery life, particularly idle, is far better. I don't mind plugging in. USB-C connector is long overdue. No more fumbling in the dark trying to plug it in, scratching the bottom around the connector in the process!

The built in battery monitor is bad. I ran antutu benchmark once and it tonight it took up the equivalent of my whole battery. 5 minutes of app time and only 3% in real life. I have done a couple of full battery cycles to just make sure the software learns the top and bottom ends of my battery. Slowly figuring out what is killing battery and what not. If I have extra drain it's because something is glitching. I have been unplugged since 1 am last night. Still at 10% with almost 5 hours of screen on time.

I don't feel I disabled much of the phone, all I did was disable approximately 12 apps that I don't and or won't use, and at around 85% battery left, I turned on a custom mid power saving feature and used the phone a good amount over a 34+ hour span. This whole setup took me less than 15 minutes, so I'm not sure why you seem to have an issue with my choice in phone. It's not like I went in, rooted the thing and froze an incredible amount of apps, slapped in a custom kernel and messed with voltage and loaded some slim lightweight custom ROM. I simply used power saver and disabled some apps. This took no effort at all, simply sharing what I'd been getting, as others didn't seem to get as much out of their battery.
I got a note because I can pull serious hours SOT, multi task like a boss and enjoy multimedia on this gorgeous screen. I've had Notes since the Note 2.

I agree with the disappointing battery life. I had a galaxy 7 active and after a full day of work doing the same thing I had about 75% after my day ended ,with my note 7 I had about mid 60%. Keep in mind I dont use my phone except a little before work and on my breaks.i also turn my Data off when I'm not using my phone and yes all my bloatware is shut off. If we had root I'm sure I would be happy since I get a lot more out of my battery because of my root setup .

Battery life became horrendous the past couple of months

Hello. I bought my Mi 6 (Chinese ceramic model) in... January, I believed, maybe even February. The screen-on time from full charge used to be 12-13 hours with mostly web browsing and the occasional gaming. I guess it lowered somewhat throughout the first few months, but it was still quite high and usually over 10 hours. Now, Xiaomi released several OS updates in that time, and I suppose none improved battery life (even though I check user feedback before updating and occasionally that was a claimed improvement), but since the last update I think something went seriously wrong.
I'm not sure it became like this exactly after I updated to 10.0.1.0(OCAMIFH), which makes it even stranger, but currently my battery gives less than 3 hours screen-on time before shutting down. It also drains considerably when idle, possibly >10% over-night.
It doesn't seem right that the battery would age so quickly all of a sudden. The phone is less than a year old and the battery acts like it's 5. Is there anyone else who have it go this bad all of a sudden? Maybe something on my phone is spying on me and drains a ton of battery? Or perhaps the battery used in the Mi 6 is crap and loses capacity too quickly?
Thanks in advance.

you should check what is draining your battery (you can find it in the settings) and i would advice to do a "factory reset" as maybe after the update an app got "crazy" or dose/doze? isn't being "used", also there is an option on the app's settings page where you can select what type of "optimization" the phone does to conserve battery atm i have mine set to "let miui choose the best"

Hi! Did you for any chance bought a miband? I ask this because both me and my girlfriend have mi6 and I use the mifit app. I get around 3 or 4 hours screen on time per day while she gets 6 or 7.
Either way, don't think you should expect the 10 hours to be normal.

Nope, the phone isn't connected to any peripheral. I didn't think it should last 12+ hours (so even more than 10) for eternity, but to my understanding lithium ion batteries lose about 30% of their capacity after 1,000 recharging cycles, and I doubt I got even close to that in 10 months while my battery has supposedly already lost 50% or more than its original capacity.

Just for the record: We don't have lithium ion batteries, we have lithium polymer batteries.
But the thing that matters is, lithium polymer batteries have less full charge/discharge lifetimes.

Btw I have a mi band 2 too and I just use mi fit app for basic connection, then everything else is handled by mi band tools app + root for better sleep as android integration. And it just doesn't drain my battery as yours do. I still have around 10 hours sot here, after 14 months of use.

Oh I really want/need that ahaha I've been using this version of the app, I notice it doesn't drain as much battery, but still I almost never reach 4 hours of screen on time. Is there any tutorial where I can check how to configure mifit and mi band tools better or is it just a matter of having mi band tools installed?
Edit:
Is it this app?

@TLxda-d and my suggestion to you is making a clean installation/setup by factory resetting for example. To get rid of all these cache and also so called miui optimization sh¡t's cache too. Miui tends to be fuk'd up after a year or so.

Yes that app. Just disable everything in mi fit and use the same and more functionality in mi band tools.

Just for the record: We don't have lithium ion batteries, we have lithium polymer batteries.
But the thing that matters is, lithium polymer batteries have less full charge/discharge lifetimes.

Btw I have a mi band 2 too and I just use mi fit app for basic connection, then everything else is handled by mi band tools app + root for better sleep as android integration. And it just doesn't drain my battery as yours do. I still have around 10 hours sot here, after 14 months of use.

Are all phones using Lithium Polymer batteries?
And is it reasonable thus that my phone holds less than half the up-time now between charges?

As I'm aware of this, yes all mi 6 phones have lithium polymer batteries.

I meant smartphones in general, because I always hear "lithium ion".

Lithium-ion and Lithium-polymer (mainly know as Lithium-polymer-ion) are identical, just their physical sizes change and some of their characteristics are a tiny bit different, nonetheless i get on my mi 6 like more then 10hours of battery life (browsing instagram, playing a few games here and there [somewhat high demanding], listening to music all the time) and i also charge mine from 67%~40%-25% and i have not seen any type of "degradation" on my battery, i would reccomend you to not charge it all the way to 100% (as a way to lessen the charge cycles, i mean even if you dont reach 100% the closer it gets to "full" the more strain you put into the battery, the same goes for reaching 0%) i would also advice you to do a factory reset, as usually it is an "app" that eats the entire battery life. ( sorry for my bad-ish english, hope i helped)

My mi6 is suffering from the same sh*t... Almost 2 years old. I was on miui eu for almost one year... Never updated...
Wanted to go back to something different.. tried RR OS 8.1 final and now Mokee 9.0 but they give me horrible battery life. I did a complete fresh install with erase data.. can't make it through one day. Maybe 2hrs SOT..[emoji26]
Last night it drained 11% within 7hrs in airplane mode [emoji848]
In settings it says: no data about battery usage ..
It really annoys me since i don't wanna miss the smoothness of that ROM...
Miui eu gave me Bluetooth problems with my car otherwise it was okay, especially battery wise...
Any suggestions?
Appreciate it!

Well, let's not transform this in a Lithium related topic.
The thing is I'm having the same problem as OP, and have seen many users in en.MIUI forum in the same situation. I'm now with latest global stable(V10.2.1.0.OCAMIXM), but even after that update i was on V10.0.1.0, never rooted, never unlocked bootloader, etc. I always had good battery life, even in v10.0.1.0. But one day, suddendly my phone started a huge battery drain.
No, it's not associated with any app installation, my usage routine didn't changed, everything was still the same as before, but a ramdom battery drain appeares, did u guys get it?
Just to record the gravity of the situation: overnight i lost 20%~35% of juice, this is ridiculous!
I though to myself: It must be a battery problem. Ordered a new original one and for my surprise the problem continues.
I don't now what to do, i don't want a custom rom not based on miui because i really like it. Is anyone using the latest miui.eu and have this battery drain?
