[Q] Is it normal for my battery to be so bad?

Hey all!
I've bought my Optimus 4X HD recently. I'm loving everything! Except the battery...
Today, I've tested it again and here's what the battery is able to do!
- 6 hours of standby, 3G and Sync enabled
- 4 times checked mail for like 4 minutes total
6 Hours later: 30% remaining.
Is it normal for this battery to be so weak? I've "calibrated" (drained to 0% and charged to 100% - left it for a long charge the first time too)
If it's abnormal I'll contact the helpdesk and see if they can replace my battery, just want to be sure if it's normal or not.
Software is latest available, non-root, very few apps -- verified with taskkiller of AVG: nothing is running in background or anything.
Thanks!

I think there are some wake locks denying the system to go into deep sleep.
Search the forum for solutions, it's a well discussed topic on here

I usually get at least fourteen / sixteen hours on a single charge when I unplug it in the morning before work, varies with how long the Wi-Fi turned on, and I get at least three hours of screen time, one or two of voice calls. I also have mobile 3g data always on with alerts for email, Facebook and Google+. Usually I listen to music for about an hour and half too. I'm running the 20a euro rom official, rooted. Try factory resetting and rooting to remove bloatware and LG logging software.
Hope this helps!

Very few apps installed by you... there is a lot of stuff running in background that you don't even imagine.
Search for the threads about "battery drain" and you'll get some more info.

Do you run the new 4.1 Jelly Bean? There is some huge debate going on, how the update affects battery life. Personally, I ran into huge battery problems after updating to 4.1. The drain was especially heavy during the night, when I usually active airplane mode. With ICS I lost about 1% during an 8 hour night, under JB it was 20-30%. I read up on the threads in this forum and followed many suggestions. I started to monitor battery drain with different apps running/frozen, wifi, 3G, airplane mode enabled/disabled and so on. To analyse the battery I found the apps "CPU Spy", "Wakelock Detector", "GSam Battery Monitor", and "Battery Log" helpful.
But to be honest, I am no "android pro". I monitored my battery drain for over a week and did not find a satisfying solution for the problem. Thanks to this forum and many excellent posts I managed to roll back my phone to 4.0.3 ICS. Now my battery drain is the way I remember it and I am happy again
For me, this solved the problem. Although I do not run JB, and some of the enjoyable improvements it had, anymore. I know that for some people rolling back is no option. If you cannot locate the battery killer easily and you are willing to play around with your device (rooting, freezing apps...), you might as well roll back and give that a try.

You should explore your device and your stock apps...
My battery last in JB for so long as in ICS.
If there are differences they're small.

Yes!
Thanks all, very useful replies!
I've tried simply factory resetting it and, for about 3 hours it stayed on 100%, 2 hours on 99% and etc, very awesome!
I then set up my mail and other things and it went bad again. I had this sync symbol in my notification bar -- no clue why it was there all the time.
I googled why it was there and it's because the sync fails so it keeps trying. I removed the picasa for the email account (because uni mail doesn't support picasa and other google services) and my battery is top notch again! For now at least .

Looks like you're on WiFi which has good standby time. 3G standby is not good at all. That's when baseband_xmm_power starts acting up for me.

Following is my Battery usage still left some 17% with normal usage.

I've had terrible battery life... But when I went to cyanogen mod... It's been great for me ever since... Well two days actually. Lol

For me the same result with HSDPA. From 8:00 to about 15:00 oclock 15-20% of battery Just IM+ on, sync, some web browse + maybe one hour some games like beach buggy blitz or subway runner.

i am on cm 10.1 now and my battery is bad for now.For my case beleive or not my best battery life with some modifications is on stock ics v10h 19 hours on stand by and i still got 0% drain

mine is bad because of the baseband_xmm_power wakelock, had this on stock 20A but didn´t had on 10h... as far as i can search, there is no solution other than revert to old 10h....
I bought a spare battery so i never run out of juice! Reverting firmware is not an option for me.

i believe this wakelock is affecting every phone since 20A, just install betterbatterystats and see it plague and suck our battery juice

Battery drain, especially at idle

I love pretty much everything about this phone and can't imagine it being much better. One of the reasons I bought it was for the famed battery life. Most blogs and battery tests put it at just over the Z3 and one of the longest lasting phones out there.
However, that hasn't been my experience. I'm an Android veteran and I know how to look for battery drains and what generally causes them. I'm losing a lot of battery at idle and there doesn't seem to be any reason. Nothing shows up in the battery stats. I even tried stamina mode and the results were worse. I lost 20% over 11 hours without even touching the phone. It just sat there and lost 1/5th of the battery. Not quite 2%/hr, I know, but still significant for a phone in stamina mode and not being used.
The only thing that shows up in the battery stats are the usual suspects: Android OS and Android System. I don't have a weak LTE signal or anything.
So, I'm wondering if anyone else is experiencing fairly significant battery drain, especially idle drain. My battery life isn't horrible, but it should be a whole lot better from what I was reading before I purchased the phone.

Apologies for asking obvious questions, but are things like wifi, mobile date, auto-sync, bluetooth and NFC toggled on or off? Are certain apps repeatedly appearing in the Consuming Apps list? I tend to make sure I swipe these away which has helped when I've had similar excessive battery drain, for me these are (for example) Reddit Sync and Google Docs. It is weird that they don't appear to be high in the battery usage % list though...

Wifi, mobile data, auto sync, and Bluetooth are on all the time, as they are on all of my smartphones. These are not the cause of the drain I'm experiencing. If you leave all of those off all the time, there's no point in having a smartphone. NFC is off.
As stated, there is nothing in the app drain listing to cause alarm. Nothing in the battery stats is telling me I have an issue, which is why I'm frustrated.

Fair point, though I personally toggle them on and off as needed.
How any apps do you have installed over and above those bundled? I'd try uninstalling as much as possible then reinstalling then one by one. Or a less extreme option could be to clear cache in as many apps as you can, reboot and see if the drain stops.

I have everything enabled except Google Now and I lose about 0.2% per hour when idle. Also, I believe all the folks who are reporting battery life of 2 days with 6 hours SoT must be having very low idle drain.
So greyhulk I think your experience is not the norm, but unfortunately don't know how to help. Post up some screenshots of your battery stats.

When you look a the battery History details, do you see a lot of awake time? Also look at the top 3 or 4 items in Battery usage individually, do they show high amounts of Keep awake time while the phone is idle? A wakelock or poor cell signal are the two main causes of high idle battery drain.

It's definitely not poor signal. There is a bit of wake time, but the top 3 items are screen, android OS, and Android system. The wake time on those is not significant, either.

I'm about the same. I'm getting on average 7 hours on screen daily with everything on, no stamina mode, over 70% brightness. I left my phone unplugged for the first time overnight and it drained a whopping 1%! I've had the phone for over 2 weeks now.

Sorry to hear about your battery issues, but as mentioned, that's not the norm. Not sure how much help I can be, but I can tell you your Android System and OS percentages are about 2-3 times higher than mine so that seems related to the drain, but tracking down the culprit will be tricky. Have you considered factory resetting?

Here's are a couple screenshots for comparison:

when Android OS and/or Android System drain more than cell standby and phone idle you can rest assured that an app or service is draining your battery.
Many things can be disguised as Android System (/OS). It could be google now, location services, syncing of google drive, browser sync or an app running it's own service etc.

Android system and Android OS always drain 2-5% of a battery on all of my devices. However I turn on wi-fi and other stuff only when needed. Plus I have all the google services, google voice and account sync disabled.
But I wasn't happy with the battery life on my Z3c also. Cell standby, phone idle and 1-2 ours of screen time drained the battery almost in 24 ours. Maybe it was one-time occasion (I haven't had much time to test it since the phone is new), but I starting to have a bad feeling

That seems highly abnormal, I leave wifi, mobile data, and GPS on at all times, with numerous accounts syncing, yet battery life has been superb for me and many others.
It's been a few hours since I posted that screenshot from my previous comment, but my battery has dropped a mere 2% to 35% and my on screen is now at 5h20m. That's the drainage I've been typically experiencing with daily heavy usage.

Yep, Android OS and system are about twice what they should be, so that's probably at least part of the cause....

I'm not going to factory reset a phone a few days after I took it out of the box and set it up. That's ludicrous. It's set up exactly the same as several of my previous Android devices, none of which had this kind of drain.

I am seeing the same performance as you. Honestly, at the end of the day I still think the battery life is pretty solid, but not up to the legendary levels others are seeing.
Some guy said he left his phone sitting there overnight and saw a 1% drop? That is insane.
As an aside, how are you showing the Android L on screen buttons?

Factory reset is the lazy answer and should only be a last resort, especially when the device had only been active for a few days.
That would be like telling someone to format their computer every time it slows down a little.

A factory reset at the very start is the best time to do it, rather than wait weeks, months from now when it would really be cumbersome, but anyway, you do whatever you think will help. I already tried offering help and you were pretty rude about it so I'm done.

You're kidding, right? Two days out of the box, I have every account set up, all of my music downloaded, all of my apps set up, and my interface tweaked to be the way I want it. It's not any easier now than it will be three months from now. There's also the fact that the device shouldn't run this way out of the box.
Whenever there's a battery thread or a person asking for help on this forum because they have a weird drain, there are two predictable responses that will be offered almost immediately:
Turn everything off - Yes, if you toggle everything off, you'll get good battery life, but then why even have a smartphone? Most modern smartphones are capable of getting decent battery life with all radios on all the time. This is not a solution.
Factory reset - I work in I.T. If I told someone to wipe their computer every time they reported an issue, I'd be out of a job. That should be an absolute last resort. I could see it on a phone that you'd been using for months that suddenly had battery issues and you couldn't figure out what the cause was, but a phone that has been set up less than a week? Please.
These kind of offered solutions aren't helpful, yet they're always the first ones offered. It has been this way since I took it out of the box on day one. So, it either it doesn't like one of the apps I installed from the get go, or it has another issue, or is defective. I mainly posted this thread to see if others were having my experience and a few have confirmed that they are.
So, I'm sorry if you're butt hurt, but I certainly wasn't trying to be rude. I was just disregarding a solution that I predicted someone would offer that is not an option at this point (and really shouldn't be). Anyway, thanks for trying, I guess. Just please be aware that if someone comes here looking for help, they're doing so because they don't WANT to wipe their phone or turn off all of its features. They're looking for an alternative solution. Even newbies know enough to wipe their phone when things aren't working right and it's the last thing they want to hear if they ask for assistance.

Actually without having the phone in hand there is little anyone can do to tell you what is draining the battery, the suggestions given are typical of tech support help if standard things don't work. So you can either take those suggestions or do more research since you have the phone in hand and find the problem. Based on the information given there really is no magic answer to help you.

Let's discuss this battery problem

This is not another, I love this phone BUT the battery is too small.
Currently there is a massive bug affecting the T-Mobile (possibly others) Galaxy S6 (unconfirmed on edge)
Symptoms
Massive Battery Drain while Idle
Cellular Standby top Usage in Battery Stats
Random WiFi issues
Self Diagnosis
Go into Battery
Tap Cellular Standby and remember the "Total Connection Time"
Go back to "Battery" and hit refresh
Check Connection Time again
If the time increases but you are NOT using any applications, on the phone or downloading you are affected by this bug.
Fixes
Turn WiFi calling OFF
Disable VoLTE (VoLTE toggle is in the Phone App/More/VoLTE.)
Update - Turning off WiFi Calling along with disabling VOLTE appears to have patched this issue for now. You can still use WiFi like normal and turn that off and on and it shouldn't have any issues.
So lets discuss this, I have not been able to fix it. WiFi on or off, WiFi calling enabled or disabled nothing seems to correct the problem. Its as if the phone is ALWAYS on a call.
Edit- VoLTE seems to have corrected the issue somewhat. What I did is turned off VoLTE, Turned off WiFi calling and then turned WiFi off and back on. My Connection Time hasnt moved since. How long this patch lasts for, I don't know.
Mods - Please monitor this thread if you could for battery naysayers and complainers. We are out to diagnose and fix the problem, not complain about it.

Thanks for starting this thread. I have tried pretty much everything, including uninstalling/disabling most apps, turning off "keep awake" for what's left, etc. I just tried turning of VoLTE and I still lost about 2% in 15 minutes with my phone just sitting on the desk (no use). My next course of action is to try a wipe. I really don't want to take this phone back. I still think this is some sort of bug with 5.01. My Nexus 6 had battery life issues until 5.1 and now it's awesome.

Okay the VoLTE trick fixed my high cell standby drain.

I've used quite a few lollipop builds and I've noticed on just about all of them (including the s6) Google play services runs pretty high. Haven't had the phone long enough to accurately test, but I'd suggest for those seeing it run pretty high to completely disable auto update of apps. That should help limit its ability to wake up the phone.

I actually disabled wake for that app using App Ops. Nothing in Gsam or regular battery stars is telling me anything.
I just performed a wipe. If that doesn't do it, I give up.

Ok guys let me throw in my 2 cents.

that was yesterday usage. I had wifi on the whole time yesterday.
Now today usage wifi off since 100%, i have no ****ing idea why facebook is using that much, ive use it 10 mins at most.

Facebook is like a hydra when it comes to app permissions. It has the most permissions to your phone with few apps to rival it. Use an app that blocks particular functions you dont use in the facebook app (GPS, contacts, etc) and just install this (must be rooted) https://play.google.com/store/apps/details?id=com.findsdk.apppermission&hl=en

I realize it hasn't been a full days of use yet, but the Cell standby sums up the battery issue drain. I'd prefer to keep VoLTE on, and we should be able to without this being a problem. It was on, on my G3 and I didn't have such significant Cell standby battery drain. Any idea of another cause?

So, I finally caved in and wiped, even though I have had the device since Monday and battery has been bad all along. Prior to wiping, I was losing around 2%/15 minutes (8-10%/hr) without even using it. After wiping, seem to be losing around 4%/hr. I am not using it at all, just testing the idle drain. It's definitely better.
My question to the fine folks here: Does 4%/hr with no use seem reasonable? I only installed minimal apps and none of them are doing any kind of autosync or update. I have one exchange account set up through Nine and then my gmail account.

4%/hr completely idle still seems high

For me, even without ever turning on my phone, it's syncing with breaking news apps, facebook, twitter, hangouts, gmail push, work email push, a couple online RPG games pushing me alerts and so on. My battery drain ironically isn't stemming from apps syncing and emails/alerts being pushed constantly throughout the day. It's the cell standby for me.

contributing factor?

Seems to be the cell standby for me too. Disabling WiFi calling and VoLTE has fixed it for now.
Is there a Samsung support channel where we could get this recognized? It seems really asinine that people are exchanging the handset for what is clearly a software defect.

VoLTE seems to be my problem for now. Disabled it. And fully charged it to 100% and its now at 75% and cell standby isn't even on the battery stats list.

So, I can't believe I'm saying this, but a factory reset totally resolved my battery issue. It was only 4 days old. I couldn't see how it could have possibly been fixed by that, but it was a last resort before returning it.
Now I have some pretty normal Battery life. I love this phone!

If you hadn't been a douche in your follow-up reply, I certainty would consider it.

Having this issue as well..after having a nice battery cycle of almost 5 hours sot I'm seeing the same thing in bbs, losing 6% an hour idle. Will try the fixes to see if it helps thanks guys

so im getting the edge on the 15th
should i factory reset it right when i get it ?

The only thing I did out off the box was take the OTA and root. Maybe the OTA set it off? I pretty much have the same apps installed now.

[Battery Life] OP3 vs IP6

Hi! I know Android since 2008 (HTC Hero), had tons of devices and (have to) use IPhone6 Plus for work.
Can someone please explain why IPhone is basically not draining battery when screen is off? I can put my IPhone with all services running...Facebook, email, Google, Instagram etc...If I dont use it 24h it maybe looses 3%...
But on Android...not matter what I do (Greenify, disabling notifications for Facebook, Instagram... etc..) I don't get anything close to that. I discovered across multiple devices with different ROMS. With my fresh OP3T it is not any different...
What is Apple doing differently here?

Google has more services that sync in the background than apple by default, so things like location history (which I would recommend turning off) and sync for apps like Facebook that can't be disabled (unless you use Greenify) are the most common drains.

I know But even if I change massively on Android incl. Wakelocks etc there is not a lot of change. Facebook I had e.g. on Cyanogenmod as "keep active = no" and others as well...But IP was still way much better. And I get all updates on my IP6 incl. ebay, messages etc....
Honestly it is annoying because stand by drain should be at least the same with all the measures we can do with a rooted device...but in reality IPhone keeps e.g. 100% for at least 8 or 10 hours....
I know location history has definetly some influence...is there any way to send location history maybe only every 10 min?

That's all due to optimization of the app code and the os

Set localization to battery saving mode, and you should get better results on Android. IOS is better optimized though so you wont get the same results on android. Also if you suggest on battery stats you shouldnt comaper androids SoT and ios "device active" or something because they are not the same.

I know it's really bad. Look at my results. Can't even run for half day on battery

If you want really disgusting battery life, give the moto z play a try. My wife got one recently and it is unbelievable. +10 hours SOT over 48 hours with sync on and no battery saving techniques. It's only got a 3500 mah battery, which leads me to believe CPU efficiency plays a bigger role in battery life than optimization of the OS.

Because your device doesn't sleep, if it sleeps (screen is off) the battery drain should be way closer to a solid line that barely goes 1-2% down. Buy you are ilon Nougat CM 14.1? It's known that sleep is currently broken on 7.1 Nougat for Oneplus 3.

I think there is something really draining your battery or your battery is dieing.
Look here cb 8.
Download betterbatterystats this should give you a clear view what is the cause. Here an average drain of 1.7% per hour.

Hi I have better battery stats installed nothing significant in there too. I am. Running 4g all the time may be that's why the drain is so bad
Sent from my Pixel XL using Tapatalk

thank you for all the feedbacks. Just wanted to start discussion about it!
Real life experience with my work iphone 6plus yesterday.
3% at 8pm...sync and all services on (gmail, location for google, facebook, ebay, instagram etc...) and running. Phone was ringing twice because of skype call coming in, but was not used...Next morning 7am still at 2%....
Android got better, much better, but still is far from that....pretty much the only part I like about IP

ip6?!?..
It's that a phone?!?..:laugh:

The Iphone has better battery life, easily.
However, the battery life on this phone is such that it shouldn't be a problem... Who goes a day or two without access to a charger?
If you are doing nothing but watch Netflix and play Pokemon all day, yeah, the OP3 will run out of juice... But at that point you don't have a social life, so you can hug the wall and recharge and not miss a beat.

Phone was at 98% at 1:00am and then 96% at 8:30 when I woke back up. All sync is on. No greenify or anything like that. I think standby drain is just fine.

iOS does too. Here's a screenshot from my iPad. I was getting all notifications on time and did everything on it except game.
Over three weeks off the charger:

"Stand by 22 DAYS"..., hilarious. Apple drollery..

If I was a hardcore user, (which I'm not,) all that would concern me is whether my phone could last a day after a few years of use.
As a light user, its nice that my battery can go days but that's what it really is, a nicety.

Dunno about OP but my IP6 always had at least 8-10% battery drain overnight, and I never even had Facebook on it (just Messenger). OP3 is at 3-6% most of times, depending on how many times it got woken up due to notifications.

My battery life is just perfect.
Beta 8 Nougat.
Beta 9 is even better.

Poor battery performance, what to do?

Hey guys, I'm wondering what can I do to improve my Note 8 battery life. Seems to me that is draining and I do not get the chance to use it too much. Maybe you have an idea how to optimize and track the apps are overusing the battery, so far I was not able to detect which app/component drains my battery. Even Samsung seems that doesn't know since there is no message regarding background processes with heavy usage.
Basically I finished fully charging at 9:15 AM and now 16:15PM time I started to write the post and make the screenshots, it has 16%. What I did all this time with the phone, was:
- a bit of browsing,
- make one NFC payment,
- have the S3 gear connected on bluetooth.
- few twitter messages and viber really small usage. (less than 40 messages overall)
So here are my settings
- WIFI is off and I'm using 3G connection (I stopped LTE thinking that requires more battery.. , correct me if I'm wrong please),
- screen not even on 50% and auto brightness off (using HD+ and a dark theme, everything is so dark!)
- AOD
- no led, no gestures (most of them I turn off for testing purpose)
- Medium battery saver on.
- No phone calls
- few notifications (not more than 20, also the notification is optimized to apps I'm concerned)
Any suggestion how to make it to end of working day .. at least?
I was waiting so long for a new note and now I'm a bit disappointed and I hope that is something I do wrong..
Funny is I just realized that by mistake I put the phone on airplane mode while making the screenshots, still percentage was flying away even like this. I lost 2% making screenshots in a matter of couple of minutes.
Please find the screenshots attached in the link down bellow, were to big to add them to the post.

Thanks!

you might have some apps draining battery. I'm used to a rooted phone, so I'd always check with wakelock detector, but I'm not sure what you can do without installing an app as a system app.
Try factory resetting your phone and using it without installing anything for a day and see what the battery life is like. If it's significantly better, install your apps 1 by 1 until you find out which one is causing unnecessary cpu cycles or wakelocks.

But I wonder, I shouldn't see the heavy usage on the battery info page? Like which app does most of the usage and time spend in the background or CPU?

I had excessive battery drain, about 10-11% an hour with every off . A full factory reset cured the problem.

What's your screen on time usage? 5-6 is probably the normal amount you would get with most phones (This is the most important thing if nothings draining the battery). And yes, it seems you might need a factory reset.

You won't always see this as it could be a byproduct causing a kernel wakelock.
Either way, something is acting incorrectly. The only way to really figure it out is to start over and try things slowly till you find out what it is.
For instance, on my nvidia shield tablet k-1, I was getting horrendous battery life on every single rom, stock or AOSP/Lineage. I found that I was getting 30% wakelock killing ~20% battery life per day when it should be sub 5%. I found that wifi was causing these kernel wakelocks and setting wifi to be disabled with the screen off unless charging fixed the issue entirely.
Now, that anecdote likely has nothing to do with what you're experiencing, but note that you can usually find out what's wrong from trial and error.

I've had my note 8 for 6 days now, and battery life is excellent, i mean i have wi-fi and 4g lte on all the time, bluetooth on all the time, sync with 3 emails, Facebook, weather widget, weather screen refresh every 30mins, location high accuracy, edge lighting, aod schedule 7pm-7am, was 100% at 6am, played games on it lots, used the phone 2x, 1 hour call and a 30 mins call, text messages, it's 130pm and I'm at 55%, try a factory reset then log in to your gmail then just try to update the phone if there is any. Then reboot then start installing your apps. If it doesn't work call carrier customer service and complain about the battery not holding up like some people you know who has note 8. They might replace it with a new one.

Phone died 15-20 minutes after I did the screenshots, so a bit more than 2 hours...
So.. yeah.. I will try a factory reset and start install all the apps bit by bit and see which one causes the troubles.. hopefully is nothing more than that.

Did you restore a backup or did you load your apps fresh from the play store?
I've had horrible luck with issues like battery life restoring from backups. I always install apps fresh.

I did a google restore from backup! Damn! And I was thinking that I should maybe to a clean, one by one app install.

My battery life is also not great but im using full resolution and when i remember time when i got S6 edge on launch....the battery was horrible but after few updates it was perfect so stay strong and wait a bit

can you translate "not great" in hours? :laugh: Because I will say that mine is second after horrible.. with update done.
I will start the reset in a short while and I will test it tomorrow with minimum apps installed.. those which I really must have in a working day..

Maximum 5 hrs on wifi normally about 3-4 battery is not great on note yet....some optimalization would be nice

I use Ampere to monitor the instan drain of current. In a quiet situation (screen on, internet or tapatalk browsing, gear connected, wifi and data turned on) you should have something 200 mA drain.

Maybe some of the settings changes you're making are somehow rendering your phone less efficient.
I have the USA unlocked version and use it as it came without changing to a dark theme or turning anything off and the battery life is much better than yours.

I restored from a helium backup. My battery life wasn't good for about a week but it did last all day down to 20-30% at the end of the day. After a week it has improved maybe due to apps updating. Now I'm at 70-80% at the end of the day with moderate use. I have disabled several apps I didn't need as well.

Seems like it's hit or miss with the battery life. I see a lot of people happy and some are having problems. Hopefully Samsung might push a update to help.

Get cpu spy and verify that your devoce is going into deep sleep when off(mine wasnt at first until i froze/removed some rouge apps). Install accubattery and do a benchmark and see how your battery does. At least do 6 discharge cycles first to see an average. Also, in device maintenance, you can make all apps doze when not being used now.. this is a new feature. Add all of your apps and they get put to sleep immediately. I get 8 hours SOT this way
