I'm on Stock 2.2 US and Battery Life is HORRENDOUS. I have the Moto Charge app that displays actual battery in the status bar. I charged to 100%, wiped battery stats, turned it on and after 6 minutes of no use, I'm at 97%. What am I missing here?
Are there any apps constantly running in the background?
Do you have bluetooth/wi-fi/gps switched on all the time?
Are you using your phone somewhere that's unusually hot, cold or humid?

No, no, no, no, no
How long have you had it?
Has the battery always been this bad?
Has it only started recently? Is there some sort of cause, something that happened that has brought about this poor performance?
I just got the phone from a friend but I do not believe it to be an issue directly related to this specific handset.
Having GPS "on" all the time will not drain your battery as it is only being made "available" when an app needs it (mine is always checked and has zero effect on the battery until actually used). Did you do a factory reset after installing 2.2? On the Moto forum many issues are resolved with a reset.

Lithium-ion batteries have a big drop off at the start of the discharge profile.
They will then maintain a fairly steady state between about 80% - 40%.
A 3% change, therefore, from 100 to 97 is not equivalent to a 3% change from 80% to 77%.
I'm pretty certain it is specific to your handset - most Defys have very good battery life.
Here's my handset:

At that rate, it should last ~5 days.
There are always something running in the background. Install a cpu monitoring application and see if the cpu is running wild.
In my case, 1% power lasts for 3~5 minutes usage (game, movie, surfing etc), or 2 hours standby (wifi off), or 1 hour standby (wifi on).
I checked Battery Use, there is nothing crazy. I've also checked Battery History and nothing is using the CPU or keeping it awake. I actually wiped the phone last night, didn't have a sim card in it and left it on over night and it lost 14% in 7 hours. It shouldn't have even lost 2% given that it wasn't connected to a cell tower. I have wiped it twice.

I am of a differing opinion.. I think these android devices have terrible battery life.
That being said, invest in a few of the cheap Hong Kong 1800mAH batteries on ebay.
I had a good experience ordering from "farmerseller". Curiously, I ordered 1500mAH batteries but received 1800 mAH batteries..... it took a while to arrive, but they work great and the charger is nicely designed.

Compared to what?
What's your frame of reference?
I'm not aware of any other smartphone with specs similar-to or better-than the Defy's that gets anywhere near the battery performance my phone does.
Everyone I know with Galaxy Ss or Desires charges basically every day, one friend with an iPhone4 can get a couple of days out of it but most are only a day, friends with Blackberrys get a couple of days or so.
I regularly surpass 3 days of what I would call normal usage - web browsing, texting, a bit of gaming and the odd call here and there.
Are there any ROMs known to get better battery life? On both my N1 and NS, certain ROMs performed LIGHTYEARS better than other ROMs in the battery department. This is a well known fact that Android is inconsistent on battery life.
So I wiped, re-wiped, flash the beach update.zip, wiped, re-wiped and I'm not confident the wipe is working. http://forum.xda-developers.com/showthread.php?t=988036
Regardless, I also find it odd that my battery was at 85% and, after the flash/wipe, it charged to full in <10 minutes.
Give it a few days of usage and see the results afterward. Basically it needs some cycles to re-create the battery stats after wiping.
You can also install Powertutor to check what apps are "consuming" the battery.
From my experience: with light usage I made once 3 days but normally 1-2 days is all I get (3g, some talks, 30 min browsing, some ebook reading). It was the same with my past 2 Android phones and some 4 Win Mobile phones...
When you are in a really tight spot do the usual tricks: 2g only, disable APN, don't play too much with the phone. You will probably get 3-4 days in one charge
I updated to 2.2.1 also, and battery life went right down the tubes. I lived with it for two days, and then did a factory reset, and now I have better battery life than with 2.1. I really didn't want to factory reset because of all the fine tuning I did, and not to mention re-downloading all the apps and setting them back up, but I must say it was worth it. After 13 hours I'm at 30%, and that is with heavy use. I started at 100% and in 10 hours without using it much at all, it only dropped 10%, so 1% an hour I can live with. Once I started playing game it went fast, but that is to be expected.
Ahhh!!!!! You guys are killing me from laughter. Don't take this the wrong way....but read more items on these forums...they are a welath of information. First off.... battery stats are wiped. It will take a few days of charging/discharging for the phone to get an accurate idea of actual use. It needs a baseline created. Don't worry yet. It can take up to a week to get really good stats. As for the horrible life on 2.2....did you wipe battery stats before flashing? If not thats your problem. You have to wipe the stats when you go to 2.2. Different profiles and usage. It's mentioned in a number of the roms. With steady hard usage I'm averaging about 2 days between charging. On standby with no use the best I have gotten so far is 6 days. RTFM.... Hope this helps out.
Is it just me, or is the battery spontaneously getting better? I don't use any juice defender or battery-saving apps, no setcpu, I have 4g data (not in an lte area), wifi, push email, a live wallpaper, and gps enabled (though it only comes on only when maps uses it, of course) at all times with normal automatic brightness on the screen, and I'm on stock rom, and I swear the battery lasts longer and longer all by itself. I used to get maybe 14-18 hours of moderate use, but now I get a little over 24 hours. Super heavy use, (and I mean streaming, screwing with framework-res.apk, backups, installs, etc) I get at least 12 hours, and if I'm using it lightly (still texting 10/20 times a day, push email, web browsing maybe half an hour a day, maybe a couple 5/10 minute calls), I get a day and a half, sometimes almost two days, like below:

I don't think it's the battery, since I have two and they behave very similarly, so I'm not really sure what it is. Even when I visited some friends in a lte area, with lte active, moderate use, I was still getting around 16 hours. Anyone else experiencing this sort of... healing battery?
Pretty obvious your phone is draining heavily when in a lower signal area. Also, you have a TON of wakelocks. Not sure what you're running on your phone but there's something or many things keeping your phone awake despite your screen barely being used. I would expect my phone to last 3 days with that kind of usage...
Well, like I said in my other posts, the phone seems to improve itself in its battery usage. The first 2-3 weeks, I could barely hold charge for a whole day. Now, almost 2 months later, I can leave the phone uncharged from morning till nite with average use and still manage 5-10% left charge.
Haha, well, you're probably not going to get three days out of a nitro. Sorry! =)

My experience is the same, the battery efficiency improved over the 1st month + of use.
My understanding is that rechargeable batteries have a "break-in" period, where it takes maybe a dozen or so cycles of (dis)charging to reach peak performance.
It seems with our batteries it just took a bit longer to reach its' peak.

I agree. That is phenomenal battery life iamkonrad compared to what I've been experiencing..
Oh, when are you going to share those status bar goodies with the rest of us. ;]
If I'm not mistaken android collects battery stats, that uses to more accurately detect battery life. Perhaps that's the case here? If you clear batter stats with CWM, you should see different results.
could you also put screenshot of display usage. display takes a lot of power
idea
What would really be nice is if somone would make a thin case with a slim solar panel in the back of the case, you could lay it face down and have it charge from your office lights or at least supplement the battery... lol
How about make the screen itself a solar panel?
Well looks like it's already been thought about: engadget.com/2008/05/26/apple-files-patent-for-solar-cells-on-portable-devices/
Solar panels of that size would provide a minimal amount of juice to the device. It wouldnt really be worth it until photovoltaic efficiency improves..

Perhaps 2.5x5 solar panels are not able produce 1.1A juice.
hi itiskonrad. could you tell me what is the name of your battery monitor?
I don't have one. What I'm showing is just the battery info under settings, about phone
I just got my Glide a few days ago. From the specs of the phone and reviews online I was expecting the battery to last very long, but that hasn't been my experience.
My battery was going down about 10% every hour which means I would barely make it through a work day without charging it again.
I found a great app called Battery Mix that tracks battery usage and estimates how long the battery is going to last. It shows a number called P/H (percent per hour) which tells you how many percent per hour the battery is going down (or up if you're charging). You can find the app here: https://play.google.com/store/apps/details?id=jp.smapho.battery_mix
When I first installed the app I was getting about 12.5 P/H which means the phone will only last 8 hours. I then uninstalled a few apps that use battery, but that didn't help much. Somebody said their battery improved when they formatted their SD card, so I just removed the SD card from mine. Now my battery consumption is down to about 8 P/H. The best I've seen is 7 P/H. This is better but still would only get me 12 hours and I'm not running all the apps I would like to be running.
I have JuiceDefender running now on the balanced setting. I'm running the Osimood ROM with Android 2.3.5. I've removed all background network polling apps like Facebook. Android OS is using 56% of the battery followed by display at 15%, so there isn't anything else that's eating up my battery.
How is the battery life on your Glide? Could you please install this app so we can compare numbers?
Woah, 56% battery life for the Android OS?
On daily usage it barely gets above 20%. The screen takes most battery life.

Thanks for the info.
Mine has been sitting on standby most of the day so that's probably why display is so much lower on mine than yours.
The high percentage of Android OS doesn't really worry me. It doesn't mean it's using a lot of battery; it just means it's using most of whatever is being used which could be a small amount.
Mine is doing much better now. P/H is down to 4.3 which means it could last 23 hours.
I really think the problem was the SD card. I'll pick up a different one after work today and see if it works better. I need a bigger one anyway.
I also found a thread that talks about corrupt image or video files on your phone causing bad battery life. That could definitely be what I'm experiencing. Should be fun figuring out which image is causing the problem.
what about downclocikng your cpu to 800? it will help i belive.
OK just installed it. I will let you know how mine is doing in a few days. I am fully Rogers stock.
I replaced the SD card and it seems to be doing better now. There may have been images on that card contributing to the problem.
I actually had GPS, wi-fi and bluetooth on the whole time. I've turned them all off now.
I've also underclocked it to 800. Thanks, taiber2000.
It looks like for the last hour it only dropped 3 percentage points.
If you are rooted and have ClockworkMod installed, you can sometimes get better battery life by resetting your battery stats. I think there are even some apps for rooted phones that will do it, but I don't have any experience with them. I can say, however, that resetting my battery stats using CWM increased my battery life significantly.
See here for one guide on how to do it: http://www.droidforums.net/forum/bugless/111009-get-better-battery-life-reset-battery-stats.html
sjbotha your welcome.
i belive i will do the same when i'll get my phone as well. altugh i will install the OC rooted kernel for better overall performance i will still downclock via software, not need the extra sterngh for my uses and i better have longer use time then CPU power.
I get 4.9 but the other day I was getting 12. All I did was Reboot my phone and I haven't started many apps. I think when they start they stay in memory.

Mine depends on usage:
-about whole day wifi-on with 3 hours games and calls; if battery is 100% at 6am, it will be 20-30% at 10pm
-whole day HSPA+ on, 2 hours phone calls + SMS/MMS, emails etc; if battery is 100 at 6am, it will be 50-60% at 11pm or before I sleep...
in terms of P/H:
-i get 3-5 P/H when wi-fi, Auto-Sync is on.
-i get 2-4 P/H on HSPA + Auto-Sync on.
-about 1-2 P/H or sometimes a straight line on Battery Stats when Idle, no data connection and/or auto-sync is on.
in other words, the glide can handle my needs in a whole day without completely draining it's battery.

I am stock rooted
This battery drain is so pathetic, please help me out on this one guys.
I charged to 100%, then played games for like 50 minutes, Plants Vs zombies for around 32 minutes and Kingdom rush for the remaining.
Charge became 84% , not sure if this one is to be expected.
But the main issue was the drain during screen off, i went to sleep when the charge was 84% and the device was screen off for almost 8 hours,
I woke up and checked, now its 66% ???? . really around 18% drain during a 8 hour screen off window
This is so lame, i checked the battery usage, nothing seems out of the ordinary, yes WIFI was On the whole time, is that the reason..
Does the notifications cause battery drain?, i had received some mails and t-mobile my account crap had sent some notification and LED was glowing all along.
i moved from note 1 only because of the stupid drain during screen off, its annoying , i know we can switch off WIFI, data, restart the device and use some app to reduce the drain, but i thought the battery will be good out of the box with Note 3, this feels the same like my note, no difference, something is messed up.
Any help is appreciated sorry for my bad English.
that idle drain seems very excessive. I lose like maybe 1% overnight. have you managed your accounts and only sync the necessary things? that could be a big drain.
Yes thats very excessive , thats why i am losing it, i did check for syncing, apparently nothing was running overnight.
Could be because i have only one point in the network signal? , not sure, i did check on the Cell standby it said "Time withou signal 0%"
i never had 1% drain overnight , would be nice if i can find out a way to make it work for me as well.
Call me strange, but if i am going to be sleeping, I plug it in. When I wake up even with just a nap the phone is fully charged.
i do too.. but i want to check the battery drain during sleep, often when traveling, i wont even use the phone but it would have drained , that's why i am checking how bad the drain is and the ways to fix it.
not sure you need these setting enable or not, but try uncheck all in Location Services under Setting.
Maybe you should start with basics and see what have you changed, since this drain begin?
For example I was trouble shooting WiFi calling and followed one of suggestions to shut down WiFi power save in service menu. It didn't work (updating router FW did the trick) and I forgot about it, but then I realized my phone was discharging 20% overnight (yeah, I charge when come home from work, by the time I go sleep phone is fully charged) and this was way too much. To make long story short, once I put WiFi save mode back on, I get 3% discharge overnight as it should be. The problem with such high discharge rate was that the phone barely lasted a day of light use and if I forgot to charge it night before it would be dead before morning. It also kills battery to have it fully charged daily, battery will lasts much longer if the charge is light (80% to 100% for example.)
Yup, i think it was this Wifi power save option in the service menu, i had switched this off and forgotten about it. thanks for reminding me .
i will check tonight as well.
Bad thing about this setting is, its very hard to pinpoint if you had forgotten about changing this setting, it wont show up in any of the battery usage app.
Go into wifi, hit menu and go into advanced settings. Uncheck wifi always scanning.

Those 2 games kill battery like a mutha, even if you kill the screen. I always use androids built in task killer by holding home button for a few seconds and killing battery hogging apps like those. If i do decide to end up installing those again and playing them i can expect shorter battery life for sure. Ever since i stopped gaming on my phone less and just game on my 360,ps3 and now wii u(kids got 1 for xmas,mario 3d world is addicting lol) ive seen huge boost in battery life and light to normal battery consumption on common sense settings for our phones.

Yeah idk I barely use my phone and still only get about 12 hours out of my phone. I think 4.3 just doesn't like our battery hopefully 4.4 is better.
iTzXAmAzED On Note3
So I think I've found the best way to manage the heating/battery issues of the Snapdragon 810. I'm not sure if its my entire setup that's correcting all my issues or if its just the primary app.
My setup is Leedroid ROM with power saver on but only for display dimming and CPU managing. The important stuff: I am running the CPU Tuner app with a custom made profile running the On
demand governor at a 50/50 powersave bias (slider in app), and running only 4 cores out of 8. I believe this completely removes the high-power/performance cores from running. However, I do barely any gaming and performance for all other apps is very snappy and more than acceptable.
Just figured I'd share my thoughts and setup. My hands have yet to get uncomfortably warm like they usually do when doing multiple things in apps. Battery life is also MUCH better. If anything, you may use this setup temporarily until we get more kernels and developers working on fixing the issues with the snapdragon 810.
I don't have any issues with the snapdragon 810. I am still all stock unrooted and average just over 5 hours SOT. I don't use powersaver at all, not even when the battery falls below 15%. If battery life is that bad for you that you have to go to those extremes, then you probably have issues beyond the CPU.

I don't know how that's possible running stock, unless I have a bad unit or something. Then again I've tested some coworkers M9s, and theirs have issues the same as mine even though they're stock. I don't even have many apps installed, but my battery plummets just browsing the web or reddit, until I cripple the 810. Do you have any apps at all that help to preserve battery life? Or run exceptionally low screen brightness?

No, I do not use any apps to improve battery. I am on AT&T and at home I use a microcell and WiFi, so I do not get much battery drain from lack of having a good signal. I do not use exceptionally low screen brightness, but since high brightness does hurt my eyes, I do keep it around 33% and only raise it higher as needed. Overall, in comparison to other devices I have used and have or have had in the household, while not the best, I do find the M9 to have good battery life. And another good thing is, there is this update coming that improves battery life. Here is a current screenshot. Not half way through the battery and I already have 9 1/2 hours of life and just over 2 1/2 hours of SOT.

There's nothing wrong with your phone, the M9 hasn't got great battery life period, you can squeeze a lot out of it if you go to extreme lengths or if you don't hardly use your device, for example my last two phones which i just got rid of (Note 4 and an iPhone 6)
The Note 4 would last over 1 day comfortably as it was my main phone, the iPhone 6 however was simply a work phone, this bad boy lasted 4 days and 22 hours on a single charge, running IOS 8.1.3. I have a screen shot of it at home on my PC i'll upload later, the point i'm trying to make is, this is completely down to your Apps, your habits, your set up, rom you're using, mods installed etc.
All these combined make up the footprint of how long your battery lasts, no two people are the same, just as no two CPU's are the same, or for that matter the battery in your device, some may have a really good one, some might not, even your signal can have an adverse effect on the battery, especially if it's low and trying to get the signal out.
My advice for better battery life is to set up your phone the way you want it, start by cutting out the dead weight, remove and apps that start up at silly times (use autostarts for this) , check for wakelocks, reduce wireless activity, modify the CPU settings (like you have already) and then just use it as you would, anything else you can cut out,any other accounts that you really don't need, lose them, avoid task managers like the plague and remove apps like better battery stats once you've used them, use manual brightness, turn off ambient display, turn off hand gestures like double tap to wake
Beyond this there isn't much more you can do.
