Hi guys,
Here's one for you!
After I performed the widely reported HTC Desire battery calibration on my HTC Desire S I was easily getting about 40hours usage from it. I was extremely impressed by its long battery life.
However in recent days I have been getting just a fraction of this. Perhaps 15hours at most. My usage hasn't increased or decreased and I'm struggling to find an explanation as to why the battery life has been slashed. I recalibrated and still no improvement.
Can anybody shed some light please!?

You need to run some battery monitoring tools to see whats actually eating the battery.
I'd recommend battery monitor widget this should show the amount of battery being eaten at a given time and record history, so you can determine if its a rouge application or a duff battery?!
After you install it it change Settings->Monitoring->Battery Capacity to the correct value of 1450.
Try to think about what applications you may have installed around the time the consumption changed or if you have recently added new accounts to sync.
Indeed you need a battery monitoring tool to see exactly what is going on but for me I noticed that running a GPS application and after that stoping GPS module never release completly the resources and the battery is discharging faster.
All indications shows there are no GPS connections and the module is off but the battery discharge at 2x speed than usual. I had to restart the phone and the problem is solved until the next time I start any GPS app (Navigon , iGO ..).
I use stock ROM.
You could also try, where is my android power.
It's an app that shows you which app consume how many % of battery.
Maybe the problem is related to an app you downloaded lately
Thank you for all your comments so far guys. Unfortunately I am no closer to finding out what has started to dissolve my battery.
I have done a factory reset today to rule out any rogue app causing problems.
Just seems odd that I can go from getting 36-40 hours usage down to about 15 without dramatically increasing my time spent using the phone.
Hey all
I am loving ICS on my Xoom. However, I have noticed that "Android OS" is taking up tons of battery, with high awake times. I have had it unplugged for about 3 days, and the screen has only been on for like 2 hours. However, "Android OS" is the highest battery eater on the list and has kept the device awake for over 10 hours. Anyone else seeing this? I am having the same problem on my Galaxy Nexus. Thanks for any input.
Have you tried CPU Spy? Mine shows deep sleep when the screen is off. Also screen is the biggest battery user, by far.
Yeah. I used it and it said that it spent 2 hours at 1000mhz (amount of time the screen was on) and 12 hours at 216mhz and 76 hours in deep sleep. That 12 hours is taken by Android OS, and I don't know why. It is killing my battery. Does anyone know why Android OS is staying awake so much?
It is probably apps that are trying to sync. See what you have that might be trying to update/sync.
You also may want to try uninstalling some older applications. I think I read somewhere that some older non-ICS optimized apps can prevent the OS from sleeping.

Do you know of any that are especially problematic?
I have 120 apps. Isolating the problem is going to prove to be difficult. Any ideas which ones? This has been happening with my Nexus for 3 weeks now, nobody else is seeing Android OS taking up a lot of awake time?

Just wipe your system clean and reinstall your apps. That will fix all your ICS upgrade issues.
Are you syncing email via activesync? If so, turn it off for a while and check if it makes a difference. This is what makes android os go through the roof for me on the tablet and the phone!

Is that 120 downloaded apps or 120 altogether (including system apps)? Either way, disabling auto-sync and background data before putting your Xoom down could/should help curb the excess battery drain. The only issue with that is certain apps, like Market, won't function without background data enabled but that shouldn't be an issue if you won't be using your Xoom for a while. You could search the forums or Google on how to create scripts to disable/enable background data and auto-sync for you when you put the device to sleep and wake it back up, respectively. Or just search the Market for an app that does that for you.
Do you leave your wireless radios on (wifi, bluetooth, etc.) while not using your Xoom? Setting wifi to disconnect while sleep may also help.
Thank you all for your input, however I think many people do not understand what I am saying...
I understand how to reduce battery drain IN GENERAL, what I am asking is, are people seeing battery drain faster overall on ICS compared to HC? I am, and I think that Android OS is the culprit. Is anyone else experiencing this?
Thanks!
You know, I had the same exact problem when I installed the first fully functional EOS ICS rom for my Verizon Xoom. The Android OS kept draining the hell out of my battery. I went from having about 5 days of battery life to 1 or two tops.
I decided to try a different rom. Since I don't have Mobile Internet, I decided to experiment and installed the Wingray Version of the CM9 ICS Leak(Kang) and I haven't had this issue since.
So I'm not sure what fixed it, was it because I tried a different type of rom, or was it because I downloaded the Wingray version? Not sure, but either way the problem stopped.
Perhaps try a different rom if you're rooted?
I am experience this issue on my Nexus. Try using easy batter saver. It extends my battery life very well.

I'm seeing some of the same issues on EoS nightly 49. I'm down to 88 percent with barely any use. 14 hours of up time. Android OS at 3hrs and 27 mins up time.

I'm not, if anything ICS is giving me better battery life than HC. Even considering I'm now overclocked and using my Xoom a lot more.
I think a lot of people misinterpret the battery % used though. Just because something is using a higher percent of battery does not mean its sucking your battery down, there will always be something at top of that % list, it doesn't mean there's a problem. It's a relative list. It's entirely possible (and reasonable IMO) to have Android OS at the top of your list if you've used your device for only 2 hours over 3 days! You barely used it, what would you expect to be at the top?
that's a known problem,
Android OS is also taking up a lot in the stats for e.g. the Galaxy S on its ICS port
a related question though:
I'm mainly using my Xoom for ebook reading (PDFs via ezPDF and/or repligo reader) - which ROM in your opinion offers the better battery runtime
Team Eos ICS ROM
or
the Team Tiamat Moray ROM
?
Many thanks in advance !
Android OS battery bug 4.0.3
If your android device has been off for a considerable amount of time, Android os should not be at the top of battery usage list; phone idle would be in that spot under normal situation. However, there is a battery bug in 4.0.3. After installing 4.0.4 on my Gnex it fixed the problem (from my understanding 4.0.4 was only for the Gnex as its a newer device and the Xoom wifi is slowly becoming obsolete). I'm guessing this will be fixed in 4.0.5 that will be released sooner or later... my guess is later with aging devices.
My Wifi only Xoom with Team EOS is getting 4+ days of battery life and my screen is whats taking most of the battery. I am using the latest nightly as well as the latest GAPPs. There is something running on your Tablet that is casing the problem you are having. I am having no probles with ICS at all and having great battery life. Have you tryed using maybe setcpu to setup a screen off profle. I would maybe think about doing a full wipe and starting over with the latest of everything.
My android OS was at the top of my battery usage (74%) even when in sleep mode. I used to get 5-6 days, now I get only 2 at best.
I disabled wireless and the drain goes away, android os goes back down to 2-3%.
Any ideas?
ICS 4.04 Xoom WiFi only.
Thanks
Bruce

Hello everyone!
I own a LG G3 D855 and from the moment I bought it, I've noticed problems regarding battery life. After some resets, the store changed my battery. Despite this, it remained more or less the same. I usually never pass 3 hours of screen-on-time (no gaming!) with a full charge. After that, I considered it was due to the 2K display and reports around the internet talk about 4 hours with this phone, so I became thinking it was quite normal to have this battery life (asking your opinion, guys). Notice I usually have wifi on; 3g, nfc and gps turned off.
However there's a second problem. Sometimes, at random days, like it happen today, I get android system using more battery than the screen (around 50-60%).
I'm avoiding sending it over to the warranty, because I'll be 30 days without the phone and not sure they're figure out the problem.
Any help?
PS: I'm running stock Lollipop, haven't rooted yet. Same behaviour when I had 4.4

Battery life ... oh there are many different fators that influence the battery life.
For example: The battery (capacity and health), the firmware (many the kernel), the apps, the usage, the system/apps settings, the temperature, the (wifi and/or mobile) signal strength, etc.
So it's hard to say if your battery life is "normal" or not.
For detailed discussion about the battery life on your device, please post in the G3 General > Battery Life Discussion thread.
If you think your battery is fine and suspect an app draining your battery, I recommend to install and use Better Battery Stats (BBS) app.
For some stats you will need to root your phone though. But you can record all stats and post a dumpfile from the app to the app thread, and the "experts" will analyze it for you ... helping to identify the culprit.
Thread closed. Thank you!
Has anyone noticed their battery getting incredibly worse over time? I bought my S7 on release (non edge). And since then, I've noticed that it doesn't last no where near as long. Today, for example I started my day at 7:00am when the battery was 100%. As of 30 minutes ago, the battery reached critically low (5%). From 7am all I did was watch a few videos, facebook, snapchat and then play music. But all the above for not too long.
I've also noticed that once the phone hits the 15% battery (I know due to the notification), that within minutes the battery can be done to 10% or so, without touching it.
I'm more so tempted just to take it back, unless there's an easy fix OR it's a known issue with the current version.
Thanks!

I've definitely noticed this since rooting. Maybe it has something to do with that? Like a ROM you flashed or what not? I'd like some suggestions here as well.
Thanks!

I haven't rooted the S7, it was the first phone that I've left stock from opening.
What does the battery stats say is using the most mAh?
Facebook app is a known battery hog
Obviously over time, you'll install different things, and slowly the phone will start using more and more power running background apps
A backup and Factory reset will show if there is a hardware / battery issue, or if it's purely from stuff you've installed over time
Also clearing the caches from recovery could help
yeah ive noticed this too. My usage habits havent changed but my battery life is almost half of what it was when i just got the phone.

Cache has been cleared from recovery, and I don't generally install many apps so since I've bought the phone the apps have stayed the same.
Android system is always on top. Unless of course I spend hours on Facebook.
Might have to factory reset. I've used my phone with the same apps and time since I've bought it, and I'm finding I'm charging it 3x as much.
I think it's a root issue - deep sleep.
After S6 Edge Plus, when you root a samsung phone, it won't go in deep sleep. I believe there's a fix for that.
Have you checked the battery usage stats? It gives you the breakdown on what apps are eating up the battery.
I have had my S7 for about a month and battery is about the same.
Just to update this thread for those that may have a similar issue...the other day I couldn't live with the battery life the way it was. The phone used 50% in several hours where I barely used it.
Decided to completely re-flash with stock (was stock before) as opposed to simply wiping all data. A week in, and the phone's battery life is back to the way it was. I went to bed when it was on 100% (as a test) and woke up 7 hours later with the phone on 94%, with wifi, location and bluetooth on.
Not sure what had caused it to use so much battery previously, but it's back to what it should be and that's all that matters.
hi with my s7 exynos i do 3h screen. i think there is a problem. i bought my s7 one week ago. can anyone help me?
Rooting and installing custom kernels when done right should greatly increase the battery life of your device. This is a well known guide here on XDA for improving battery life for our devices.
That being said, Lithium Ion Batteries hold less charge the more cycles they are put through, its a given fact but as you said your device is relatively new and therefore should not be experiencing this kind of problem. The way I see this is there are 3 possibilities which may be causing the said problem...
1) You have rooted the device and done some modification/s. ( which you haven't done )
2) Your battery is being drained by a service ( Like Oculus or VR ) in fact a number of reddit users complained their S7 was overheating and battery was draining really fast for some reason. Check This page out, It might help you.
3) Battery Defect, you must've gotten a "bad" model, if you haven't tripped KNOX you could try bringing your phone to Samsung and see if they would fix or replace it.
Good luck
I think this has to due to them samsung updates. As far as i know samsung been always doing things like this where they made the OS slow as hell after a while so you gonna get a upgrade sooner but a battery should last 2 years minimal without degrading.

i get like 5 hours screen on time and bout 1 day standby time but i have most bloatware disabled with the package disabler. But if i was you i would contact samsung.
This happens with Samsung updates on every Galaxy phone. It's like a curse. It's unavoidable.

May i ask if the people with these problems use the fast charge? I hearing many bad things bout this so i switched it off and must say the normal charge isn't that slow and if it can keep the battery good for longer then we all should use this.
I turned fast charge off about a week after I got the phone, was making the phone and charger pretty hot for the sake of about 5-10 mins quicker charge
Pointless really, unless you are desperate, only have a few mins spare and need as much power as possible in that short time, and if that's the case, enable it for that one time
Restrict background data on all but the most important apps (phone, text, email), dave power all but the most important apps. Battery life is fine

I bought my OP7 7 days ago , I have been experiencing poor battery life from day 1. SOT is around 3 to 4 hours , standby time is around 22 hours. If I leave the phone idle for an hour , the battery percentage drops 4 percent without any activity . I do remember receiving an OTA update on the first boot , I don't know if that was the culprit or I have been sold a lemon. I have waited for a week hoping that the battery life would improve after a few charge cycles but there has been no change.
Is everybody else facing the same issue , especially those who are on 9.5.x ?
I have to say that i do not experience any issues like that. The overnight drain is minimal, a few % over 8 - 9 hours, and overall the screen time is as expected (i daily play some extremely CPU heavy games for a couple of hours and i still get around 5 hours of screen).
I'm also experiencing the same issues. When phone idle abnormal battery drain.
Can you tell me if the phone with the cellular data turned off, uses data from your plan? Can you see that?
I had same issue with my phone so then I returned it to Amazon and I received replacement which is working fine and giving good battery backup.

I made 2 returns, I'm now with the third phone and still had the same issue. I'm losing my mind how is that possible. And for sure is all new phones with different imei.
Every user has different usage profiles.
If your phone is rooted install Better Battery stats or FK to get detailed info about the rogue process that may be consuming more battery than it should.
