Desire battery observations

I know you guys might be tired of these threads but I thought I might as well post this.
My desire is fairly new(Less than a week) and so far its been good apart from(What I though) battery life. i've been trying to improve it and I think I might have "some" progress.
Currently I'm running DeFrost 4.9 with HAVS @ 1137(4.9a) kernel with the very latest radio, I also use only 2G networks(No 3G here). I got two Gmail accounts but only one has sync(The other one is merely for Google checkout CC purchases), I got one Facebook account set to sync every hour as well as LP Facebook widget also set to sync every hour. I also got FancyWidget syncing weather every 3 hours. Apart from these I got Nimbuzz running 24/7 in background. The battery is calibrated and yesterday I did a complete discharge/recharge.
Now I plugged it off the charger 2 hours ago, it was at 100 according to spare parts. The brightness is at 2%. I did some lite browsing, browsed a bit with Tapatalk Pro and 40 minutes ago went to a market nearby. During my trip to market I had Google Navigation turned on navigating me(During both, the trip to the market and return). Now while making this post the battery is at 81%. Does it sound right?

How much time the display was on? How much time was the GPS on?

Be careful, don't be happy before time. I did the recalibration too, and found that my phone would turn itself off at ~20% remaining battery.

During the navigation, about 5 minutes for display, 40 minutes GPS during which I went into a building for 10 minutes and it probably lost signal then.

OK, this ain't good. I slept at around 2 AM with 29% battery life. In the morning(10:30 AM) it was dead(0% battery).

Sound about right. 8.5 hours with your facebook and other syncs. I don't see any problems at all. Mine does this too.

First, in the night put the phone in airplane mode (I dont think u need to check ur facebook )
Second, check if u have useless programs that are using cpu in background, if is this the case UNINSTALL that program and CONTACT the developer. We dont need to kill those kinds of app, we just have to UNINSTALL if an app doesn't work properly, untill the developer will fix it. If all people will do like me, the market will full of great apps

I don't think I have any useless stuff running in the background. All I got are 2 widgets(Facebook and Twitter) syncing every 1 hour and 3 hours respectively, one Fancy Widget fetching weather and Gmail push for one account. Is their a way I can check all the services running in the BG?
EDIT : Forgot to mention Nimbuzz running 24/7.

Agree... before I used to see 1% but after "calibration" now it shuts down itself at 8~9%

I won't rehash all of what has been heavily discussed by now in much greater depth, like in the FroYo Battery Usage thread. But auto sync with such social applications and you set yourself up for low battery runtime to begin with. Especially with a constant polling IM and/or battery widget running too. Don't expect much.
Anyway, I don't use them but weather, stocks, 5 mail accounts and news is set to auto-sync every 15 minutes and WiFi is always running if available. Last discharge as soon as I connected charger ended at:
http://bit.ly/c6R59G
http://bit.ly/bmM9oN
http://bit.ly/cMlnun
http://bit.ly/akPvr7
I slept twice for 7-8 hours each on that charge and it includes all of my daily usage including listening to 127 minutes of MP3 via headphones with the screen off.

Hmm Wi-Fi + Nimbuzz really screws up the battery . Last night I turned off the Wi-Fi and slept for 8 hours. I had 46% battery before and in the morning I had 40%. I also have disabled Auto-sync for Twitter/Facebook widget and Facebook app. Now the only running services I got are Gmail push, FancyWidget weather and Nimbuzz.

How did you manage to get such good battery life? Your phone lasted for over a 32 hours period which included 6 hours of display. And that too with stocks and News syncing every 15 minutes. Does Nimbuzz really screw you that much?

Well now datz some good battery. Which ROM are you using? Which Radio are you using?
I don't have any account/social networking syncing. Don't use wifi more than 20 mins a day. Brightness 20%. NO GPS. No Bluetooth. No stupid application sucking battery's power. If my screen is off I lose about 3-4% for a period of 5 hours, so no app sucking the battery in the sleep mode.
If i use EDGE when the battery is Full for about an hour I get battery drain of 20%
Would love to know more details on which ROM, Radio and your settings.

OK. There's not much I can say except what other guys who know better than me said here http://forum.xda-developers.com/showthread.php?t=743172
It's all usage/config/settings dependent. There's no secret sauce. Some setups and usages last shorter than others, yet further, some drastically shorter.
Firstly, I don't change something working well nor move from a setup until I've worked with it the best I could. The ROM I use daily is HTC 2.2 with root. The radio is some old one that worked perfect for me: 32.43.00.32U_5.09.00.20. I can give you some details so you can characterize the battery performance on mine better.
- H.264 sub 2.5Mbps 800*480 video playback at 18% brightness lasts 5.5-6.5h with about 15% remaining. This has been repeated more than 50 times since March.
- My average runtime used to be 13-18h since March but I knew something was wrong and drawing more juice than necessary. I kept looking (mainly at the logs). It took me months to figure out it was a few things including my build.prop WiFi/cell settings, A2SD+, my GMail install, battery widgets, eBuddy, Titanium Backup, Chrome2Phone, Pure Calendar/Grid widgets and my 3G baseband reception. Some app versions were buggy and constantly polling and returning random errors in the background. I had to eliminate them one by one.
I rectified such problems entirely and removed all the unnecessary apps installed which I rarely used. I had to revert back to FroYos A2SD with the install location mod. That took me to todays battery runtime which I'm very happy with. Chrome2Phone for instance could stay installed and be disconnected when not in use to avoid the large background drain it caused.
- I run personalized colour calibration with lowered overall luminance but more red and green with less blue sub-pixel luminance. Very near D6500 whites. I also keep most apps and my homescreens dark when and where possible. I disable button LEDs through a widget when not required (much).
- 24-39h is the norm for me in typical usage. Among much else that always includes a few short calls, some YouTube, some StreetView, some TapeMachine (audio record), some Scan2PDF, some Aldiko, some Chrome2Phone and Fox2Phone, some Tapatalk browsing, some XDA app browsing, some Quick App Clean Cache, some SpringPad, some Adobe PDF, max 15mins of MP3 playback, heavy net and NewsRoom browsing, 150-250 emails and messages and constant sync with what I listed priorly. Always 2G though, and whenever I reach areas I know have bad or no reception (causing high drain) that I'll be staying at for more than 10mins, I disable cell (frequently). I've nurtured the habit of putting the phone in standby after every use too.
- 6-9.5h display on aggregate is the norm for me. I use lowest brightness possible or 18% typically. 50% in very bright, direct summer sunlight. Just now the battery ran out after 26 hours with 9.2h display on, 13.5h cell on and 22h WiFi on.
- I have apps I consider junk removed: Facebook, Footprints, etc. The lot. So no sync or auto running for them or their widgets in the background. I also removed the base GMail because logs showed me it carried on running sync all the time even when not set to. I forced the latest GMail APK in and it has no such problems. I removed all battery widgets installed except one since they drain heavily.
- Heavy usage like GPS, lengthy calls, video recording and playback cuts the runtime down drastically which should be conspicuous. I can drain the battery fully in 5h with everything max and running.

Thats some damn battery life you have there. You are on a Sense ROM? Do you actually use Sense? If so you're either exaggerating or I'm a total fool(I'd prefer the latter).
I've been trying to fine tune the battery, currently I'm using DeFroST 4.9 with SVS 998Mhz @ 1275mv kernel with 17_2 radio. Re-calibrated the battery yesterday and compiled a custom wi-fi module containing fixes for sleep disconnection today morning.
I left it at night around 3 AM with 99% battery, turned off the Wi-Fi/EDGE but kept mobile on. In the morning(Around 9:30AM) I was at around 91%. Gave it a quick charge to 100 till around 11:15 AM. Disconnected it and from 11:20 to about 11:40/45 AM I had quite a heavy chat session over Nimbuzz with my friend. My battery went from 100 to 94% in that time. After that I pretty much left it, picked it up to check a mail once or twice and sent a few messages over Nimbuzz. It is 1:40AM now and I'm down to 89%. All of this was over Wi-Fi, GPS off, Bluetooth off, no tethering no nothing. I got no Facebook/Twitter auto-sync. Only FancyWidget(every 3 hours) and Gmail Push. Brightness is at 2%(Although even then it is a bit bright, maybe it is just me).
I am using Extended control widget to see the power percentage.

Whoa ! Amazing post there. This should keep me occupied for quite some time to figure out what the heck is going on with my battery. The battery life what you are getting is really good and that is what everybody should get provided they figure out what the heck is sucking their battery that bad. Lotsa things and apps you have said drains the battery is on my phone and I haven't even started looking at logs in detail. Itz been only couple of weeks since I have this phone so I'll defn start looking into this issue.
Few questions
1. What issues did you have with your build.prop?
2. What battery widget are your currently using ?
3. You have mentioned A2SD+ also is a battery drain, was it a particular ROM's implementation of A2SD+ or older version of A2SD+ or A2SD+ in general causes battery drain ? Would be great if you could link us to the location mod

OK, It is 7:05 PM now and I am down to 70%. Nimbuzz was on all the time along with Wi-Fi(Although I don't know what happened but it switched to EDGE as if it lost Wi-Fi connectivity, Wi-Fi wasn't disabled, just disconnected). And I pretty much haven't touched it since 1:40 PM. Not as good as I hoped, but still kind of decent.
And my Wi-Fi strength isn't that great either, it is either 1 or 2 bar out of 4.

Well, I haven't done any such kernel modifications intentionally. Never had any need to either. 14.5h since last charge now, cell on 5h, WiFi on 12.5h, display on 2h and 76% remaining (actually, those stats were collected and written an hour back). The Desire display has been verified to consume at least 70% of the total device power when the screen is on. So you can't get more hours with display on if it didn't run as such.
It's HTCs ROM so of course it is using Sense. I can't do without most HTC added goods in Sense. Let alone the Mail, Bookmarks, Calendar, Stocks, Copy/Paste, Lookup, Clock, Gallery and Camera apps and widgets. The widgets I depend on work well only on the HTC ROMs I've tried. The missed Sense goodness combined with the bugs and problems I had on AOSP ROMs were extremely problematic so I moved back. Even my video recording and native playback is much better on this ROM.
To be frank, you've hardly had the phone so you'll learn much more yet. And it comes through search->reading->experimenting first. 1-2 weeks is too little for even figuring out most of the basics, unless you're moving from a similar phone and OS. For one, you'll need to actually read the linked thread to see what many observed and experienced. It took me and many others 6 months to learn things and get to this stage. Every other day I was testing and monitoring. But be aware that you can't, for instance, have the exact same setup and usage as me to have the same resultant battery life.
Had you read the linked thread you'd also be aware by now that bugs were filed for inaccurate % readings by Androids Battery Usage section. However, its time tracking was reliable in my testing.
- On your typical full discharge, how much time and % is listed under Display on?
- And for cell?
- Which A2SD are you using?
- Static wallpaper/color?
- Animation settings?
- Location on?
- Network location errors in logcat?
- Cell network chosen auto or manual?
- Did you mention all the widgets on all homescreens?
- OSMonitor/CurrentWidget values in idle screen on and idle screen off?
I use EC and SwitchPro widgets too but their battery widgets (like you mentioned) are known as ones with high consistent drain. The EC dev also corroborated this in its thread under the Themes section.
The 'idle' drops you get don't make sense to me unless there's fundamental hardware/software activity you haven't properly monitored and logged. Even kernel and I/O usage in the background. You'd be surprised at the difference one buggy underlying feature can make.

If you're actually asking those questions, here goes. Note, I am at 66% and the time is 8:56PM. And after this I'm gonna nandroid this ROM and try SuperVillainHD just for the kicks. Also, can it be that since the phone is relatively new, the battery is not up to its full potential?
Q1, 2) Battery usage is :
Display: 35% (35m 37s)
Wi-Fi: 20% (9h 44m 22s)
Cell standby : 15% (9h 44m 22s)
Phone idle: 14% (9h 9m 42s)
Android system: 6% (CPU Total: 9m 35s, CPU Foreground: 27s, Data sent: 7.82KB, Date received: 11.38KB)
Nimbuzz: 4% (CPU Total: 6m 46s, CPU Foreground: 2m 54s, Data sent: 298KB, Data received: 851KB)
Android OS: 3% (4m 1s)
Voice calls: 2% (45s)
Q3) I'm using DeFroST ROM with A2SD+
Q4) Yes, I'm using a static wallpaper
Q5) Animations is set to : All animations
Q6) GPS is disabled, if that is what you mean.
Q7) How can I check this and what would it show?
Q8) Didn't touch this, so I'm presuming Auto.
Q9) I'm not sure, so here goes. I got a Twitter widget, Facebook widget, both are set for manual syncing. Got FancyWidget syncing every 3 hours and several harmless icons. I got 3 bars of Extended Control widget and a google search widget
Q10) I don't have those, are they available in market? Do they consume battery?

I'll have to open the file for that to check exactly the changes I made. I didn't really follow anyone, just went off my own understanding and intuition. If I try to access the dir or open the file whilst the phone is not in Recovery, it'll force a reboot so I'll give more details later on this when I'm near a PC.

FroYos A2SD was nice but I needed much more space and was trying A2SD+ with various ROMs as well as manual use on HTC ROMs. Endless problems such as very remarked, consistent sluggishness in basic functioning, total boot and app load slowness, including high, persistent background CPU and IO loads and very poor SD card transfers over USB and WiFi made me sack it. I lost a class 4 16GB Kingston SD card with errors inside 2 months. I transfer 2-4GB in/out daily and many transfers started failing. Widgets bugged out frequently when you needed them most and had to be all re-setup. Video record and playback became dis-able. The phone became useless except as a toy. That's not what I bought it for but as a helpful companion. I eliminated everything in question. It was simply the SD card [over]use compared to internal memory.

[Q] Poor battery life.. being reading a lot of threads but..

I have been reading of a lot of threads about how to save battery life..
here's what I done:
1. gps off
2. auto kill w/ advanced task killer
3. screen brightness at low
4. sleep screen after 15 seconds
I have got my desire for a few months and battery life has been bugging me. I understand that modern big touchscreen will drain the battery as compared to normal phones. Using a custom rooted rom atm.
I unplugged the phone at 12:00 with data on (push, auto-sync, etc), when i woke up at 7:00, I'm getting 73% of battery life. Charged it to full again and unplugged it at 8:30. My phone the phone shutdown by itself at 21:30. It's a little bit more than 13 hours of battery.
Is it me or everyone else is getting the same number? I just installed setcpu and see how it goes.. please tell me if there's any other way to preserve more battery!

I think it partly depends on which ROM you are using. I am currently using a new ROM (which I LOVE) but I've noticed that my battery life has decreased quite a bit. It can be kind of a trade off. I love the ROM so much that I'm not going to change it but it works ok for me because most of the time, I am somewhere where I can charge my phone if necessary.
Just found this thread which might help. http://forum.xda-developers.com/showthread.php?t=755903&highlight=battery+usage I'm going to try it and see if it helps.

- Display on time?
- Cell/WiFi on time?
- Chrome2Phone (or similar) running?
- Any battery widgets running?
- Any social networking apps/widgets running?

What's the average battery life with cellular data on?

My battery life is also quite shocking, also lasts for approximatly 13 hours under normal use, but if it is in standby then I'd say it lasts for 20 hours.
under normal use:
no 3/2g mode, just wifi
leedroid 2.2a
occasional games
occasional call (like 1 in 10 hours)
1~2 messages
btw you can find display on time in 設定->關於手機->電池->喚醒時間

and your current battery status?
(sorry I type faster in Eng XD been away from TW for like 9 years now...wanna go back TT)

Do a full typical usage discharge from full to near off and see what the battery stats in that section read for Display, Cell, Phone idle and anything other (tap each one for hours and percentage).

I'm not familiar with the app but I am with FB and such and their widgets. Any app/widget polling at high frequencies like per second or per minute produces a high additional average drain which cuts runtimes, especially standby efficiency. That includes monitoring apps.
Do you have the battery widget chosen in Extended Controls, or the auto-brightness?

I can't say because supposedly, mine is well above average. It depends critically on usage and setup, too. 24-42hours with 5-9h display on and WiFi/2G always on is quite the norm on mine. Put to sleep (standby), it doesn't drop 1% until 6-9 hours. There's many many threads every week about this now. And I have many updating widgets and auto syncs running, just nothing to do with social networking since I've completely deleted from my phone.

- HTC Desire via XDA App -

19 hours 40 minutes
Standby 35%
Phone idle 32%
Android system 17%
Voice call 5%
Display 5%
Maps 4%
Dialer 2%
I am on 3g/hsdpa

Sorta new to the forum.
Just got me a HTC Desire. Rooted running CM6.0.2
If i baby it, i get maybe 6am-2pm. Heavy use, its done before noon. Ouch
Standby is ok, i left it off the charger last night and I lost 25% over 10.5hrs.
Ive got 1 twitter app on a 5min refresh. Weather is on 1hr. Screeen is down around 15% brightness. setcpu is on 245min, 998max, scaling on demand an a screen off profile of 245.
I have no idea what more I can do to get more then half a day out of it without just not using it lol.
Im pretty new to Android and all this rooting/rom stuff so maybe Ive got something screwy. I also tried a second battery from a friend, no change.

set that friends widget to longer than 5 mins and the weather widget to every 3 or 6 hours. i bet you that will get you alot more time.

Made the switch but cant see it making that much of a change.
Any other suggestions?

[Q] Is this acceptable battery life?

So I unplugged the phone at 7am in the morning,its almost 12 hours since.
My Usage was browsing 20 mins,facebook 10 mins, 5-10 texts, few apps installation,5-10 emails,5 min instagram,10 minutes of calls, 5-10 minutes reading pulse,GPS on for 5-10 minutes
And general other things using the screen to look up contacts etc.
These are the screenshots below.
Im running everything stock jellybean 4.1.1,stock rom,stock kernel. Its rooted and installed flash apk.
Now i would like to know is this really light Usage?
For this usage,is the battery life good or can it be made better?
Thank you for your time!

Check your location settings in Maps. It seems Google Now is using up the battery by using the "Update Location" feature on my phone.

Yep the location settings are all enabled.

I think the "Location" features in Google Now need some fine tuning. I believe Google Now requires that you have location updating turned on to work so I have opted to turn off Google Now to see if Google will make it more efficient in the future.

But does this constitute average battery life?

And this is the screen usage time.

Maybe I've always had below average battery life, but if I'm on any rom and I get 12+ hours of it + around 3 hours of screen on time. I usually consider it average. But that's basically what I've got on any rom/kernel, even stock.

At least your Nexus has better battery life than mine!
I'm using stock JB JRO03C ROM with stock kernel + XXLF1 radio baseband and with 3 hours screen using will drain my Nexus's battery too quick...
I gonna buy extended battery for my GSM Nexus but it will not help really much, maybe I gonna test Jame Bond kernel for Jelly Bean if that gives better battery life to my Nexus..

I'd just checked mine and I'd gotten about 15 hours with at least 100 texts, 4 5 minute calls, 2 hours of music playing through headphones, constant facebook checking, and wifi on for 50% of battery time all with google now turned on and when put on charge still had about 30% batt. left.
I am using the jelly belly v3 rom though so can't speak for stock.

Wow thats amazing battery life.
I never could manage so much and listening to music drains a lot of battery for me. I'm on stock 4.1.1, I consider mine as light usage too,wish I could get more out of it.

The music doesn't seem to drain my battery much, its only if I keep messing with the player.

Are you just listening to music or streaming it?
Sent from my Galaxy Nexus using Tapatalk 2

about 3/4 just listening the other was streaming, mind you this was into my headphones not through phone speaker

Try reducing the display brightness, it's the biggest factor in battery-drainage for me.

The display is at quite a low level. Maybe I need to flash other Roms to get better battery life.
For example right now.
My phone has been unplugged for roughly 2 1/2 hours. And I'm down to 86% and the screen usage time is only 33 minutes.

try getting CPU spy and seeing if the phone is going into deep sleep, maybe you have an app that keeps it awake?

That roughly translates to 17 1/2 hours with 3 1/2 hours screen on time. Which is pretty average depending on what apps you use.
Could you provide more details like what apps/widgets you have with what sync settings you're using, email accounts, weather, etc?
Also, what variant of the Nexus are you using? GSM? Verizon? And are you using the stock battery or an extended?

Am getting 11hours 30 minutes now with 10% left.Thats worse than yesterday with pretty much the same usage. Infact i defaulted to 2G networks and didnt even use 3G.
Sure,Im using the stock weather widget and what's this song widget.
The apps that i use daily are pulse,facebook,twitter,gmail,messages,people,speedtest(maybe once or twice a day),xda,gallery,google talk,dropbox and Gtasks.
2 Gmail accounts and 1 other email account are in push sync.
and maybe few pictures with the stock camera app
Im using the GSM international version
Im on stock battery.
The accounts in sync are shown in the screenshot(except for dropbox,everything else is on)

Its even worse now.
6 hours from unplugging and am down to 50%

Facebook is notorious for battery drain. Check the settings in Facebook and make sure to "uncheck" the location setting. Also, try to switch a couple email accounts to do "hourly" checks instead of push (unless you absolutely need them to be push). Also, try reducing the sync intervals on apps like Pulse and Twitter.
Considering you're using the stock battery the battery life seems on par with the usage your phone is getting even when not using the screen. Push, sync, and apps that use a lot of data transfer (like Dropbox) use significant battery.
I noticed the "Maps" application is using up a good amount of battery in your screenshots which means it's probably updating your location quite a bit and/or you use Navigation. Either way, that eats battery life as well. A lot of apps use location so it would be best to check those settings as well.
Also, depending on when you're using "2G", it could mean it is taking longer to pull data which might lead to battery drain.

The OS isn't always the reason for battery drain, many factors take into play.
How often you use the device.
Applications like widgets, email push.
Wi-Fi. If your not on it shut it down it else is always going to try to find a signal and drain battery.
Bluetooth. same with this.
Using the net.
Things like Google now, it's always running and trying to update info, shut it off of make intervals longer.
These are just some things to take into account, but at all use the phone different, and im not saying the OS doesn't drain but it solely isn't the only reason.
Hope this help.

I seem to be having the same problem. ..

Same here. With sync turned off, google now turned off, and most everything else that eats battery...
In the battery setting is shows that media is eating at least 25% battery.

I'm having the same issue. I read that the media drain could be caused by bad media files, but I didn't have any issues before this weird.

In my experience when you first update to a new samsung rom, the media using the battery is your phone updating the picasa albums...which stinks because it also eats your data like crazy if you are not on wifi and forget to turn off sync until wifi is available.

I've noticed faster than normal battery drain as well on my device. Normally by 4:30pm I'd be at 40-50%. Now I'm in the 20-30% range.
I'm going to try factory defaulting it soon and run it for a day or two. OR I might not even do that and just go directly to Task's AOKP or CM10.

i dont have any issues with battery drain, but i would suggest a full restore after upgrade. dont restore using titanium, just install through playstore. then report back but i doubt it will be an issue

Before everyone jumps ship, may want to try a new kernel. KT and a few others should work on the new release. Just make sure you choose one that works on JB TW and not ASOP.

I have the same problem.. After JB update there is huge battery drain. With average usage it drains almost 100%. Before update with heavy usage I was going through the day.
Maybe I should try KT kernel I don't know. I wiped all after updated, nothing saved from ICS.

It's seem the culprit is the android.process.media.
Each time i bootup,android.process.media is running for about 30 min, non-stop.
I already do a factory reset+sd formatting, but no succes.
With startup manager, i can block that process,but you need to be rooted .

I use the same settings as before i did'nt upgrade yet..i got it fully charge with no texting and calls the next 1hr its already 80%..i think i would try to cycle first my battery for 2 more days..then i'll see if it still have heavy drains..thanks for the response guyss.

Check out my overnight drian! from 1:30 to 10 the average drain is around 4% an hour, Losing about 20% overnight doing nothing.

I just got this phone the other day and immediately updated to jelly bean.Though I have nothing to compare it to my battery drain seems normal. I'm losing about 5% an hour but that is with some use (it's new so I'm playing with it a lot).
I did notice more drain the first day of use (may have been because I was using it a lot) and noticed maps was taking up quite a bit of the battery and I wasn't using it. So I uninstalled the updates for Maps and then re installed it. Battery drain seemed much better after that and now the maps app doesn't even show up in the battery report(before it was about 3rd and it seems kinda high on yours as well though you may be using it).

i'm noticing about the same battery consumption as the stock ICS rom. about 1~2% per hour when idle and sitting, 2~5% per hour listening to music over bluetooth with the screen off, and 5~10% per hour surfing the net and watching videos and stuff.

Well after doing probably 5 resets on my phone , it seems like everything is working fine . I was having issues with the battery drain ,internet not connecting, and phone calls taking 2 minutes to connect.

I was having issues with high battery usage as well after updating to JB.
I froze most every app and widget associated with AT&T and Samsung (with the exception of AllShare) and flashed KT747 kernel and set governor to ktoonservative (default settings).
I am really never a heavy user during the day, but with the same usage I had on ICS, I average 15.5 hours (with the phone at approx 15% when I shut it off to charge) - screen on time between 2.5 and 3 hours; call time between 45 min and 1.5 hrs; media (which seems to be a big battery hog) only about 6 minutes. I use bluetooth exclusively, so that radio is on all the time the phone is on. I keep sync and background data on, but only turn mobile data on as needed.

Rapid Battery Drain - How can I improve?

My battery seems to be draining quite fast. I have removed a lot of bloatware, but I'm not getting the type of performance that others are getting.
It has lost 70% in 5 hours just doing a little browsing, watching a 20minute video and playing a game for half an hour. This was with Wifi on, and mobile data switched off, and background data switched off too.
I've had the device for a week now and I've charged it every day.
Any Ideas on how to improve it?

Could well be your brightness level? Are you using autobrightness or is it on a fixed level (I hope its not fixed at 100%!)
If you use autobrightness try using an app like LUX auto brightness instead.

Thanks for that, I did have it on Auto brightness for the first few days, but the last few days I switched it off just in case it was that, but the problem remained. I will try LUX auto as you suggested.

My guess is a corrupted media file somewhere which is causing your media server to prevent the phone from going into deep sleep. When you go to settings , battery, is media the no 1 juice sucker?

I did try that, but it didn't work and the phone was a bit laggy. Why would android system take up 15% of whatever the battery uses? I'm getting so frustrated, I might do a factory reset.

How long has that screen been on for?

A shot in the dark:
Do you skype? Skype was draining the battery down in the Nexus 7 2013 even when you were not using it. I disabled it and the battery improved greatly.
Another option:
It sounds to me that there's an app that is draining the battery down a whole lot. I would try to isolate that app (by deleting each one you downloaded one at a time) until you have found it.

I don't have skype, but I like your idea - I've gotten rid of almost all the bloatware stuff. What I think I'll do now is charge it to max. DO a factory reset and not allow Google to start downloading all my apps again.
Funny thing though - when I charged it last night and unplugged it for 3 hours it only dropped a couple of percent. It started dying rapidly after I opened up a few other apps.
What I'll do now is charge do a factory reset, then switch it off, then charge to max before turning it on again. When I first got it, it turned on as soon as I plugged it in. did the same happen for everyone?

What you might want to do is download Greenify on the play store. This will tell you what apps are running in the background and then it will turn them off (hibernate).

Make sure that you leave the battery charging for about 10-15 minutes more after your cradle light turns green. Sometimes the battery isn't fully charged despite the cradle light turning green. 30 minutes on a game shouldn't be using that much battery consumption.
I usually get about 10-12 hours or more on each of my batteries ( video calling, chatting, games and my 4g is turned on 90% of the time
