Definitive Battery Thread how people are getting amazing battery life

Ok guys here is the deal. Some people claim they are getting amazing battery life and I want to know what they are running.
If you are getting great battery life like some claim. Post up this info about your phone. Let me know if i left out anything.
1. ROM
2. Kernel
3. Radio version
4. WiMax radio version
3. Are you using set cpu if so how are your profiles set up
4. Are you using juice defender/ultimate juice if so how are your profiles set up
5.Sync Settings
6.Radios always on or do you turn them on and off
7.Display settings
8.Categorize usage (light,moderate,heavy)
9.How do you charge your battery(through the phone, through the phone with an odd technique, wall charger, car charger, usb, etc..)
10.Anything else that would affect battery life/miscellaneous comments
11.Post up some screen shots of battery life unplugged and device up and awake time(be sure to reboot before your battery run as awake and up time do not reset every time you unplug)
I will be testing out my phone today and ill post my results later. Thanks guys I think this should help users get better battery life.

good luck on trying to start a "definitive" thread. I think you may be asking for a bit much of people though. 11 items? screenshots?
How do you define "amazing"? I generally get about 17-21 hours with moderate usage on baked snack 1.7 with default kernel. I have latest radio, and the 2nd latest wimax radio. I'm not running cetcpu, any of the juices, or anytype of task killer, although I do have systempanel set up to monitor all the time. I have echange and gmail set up to sync as items arrive (with no off peak times). I uninstalled FB (cuz it would try and sync even when I told it not to - even the one for sense), uninstalled news, stocks and all of the other bloatware. data always on, rarely use wifi (cuz my router sucks), and keep radios always on - i never turn them off. Moderate daily usage - maybe 20 minutes worth of calls, read and reply to 15-20 emails, 40-60 minutes of pandora, 30 minutes of internet browsing with stock browser, and my biggest battery drain is the xda app, which as some of you might have guessed, I'm slightly addicted to. I generally charge for an hour or 2 at night with the stock wall charger, then top off in the car on the way to work if I'm below 75% or so (30 minute drive will charge about 25% battery with an aftermarket palm pre car charger). Keep my brightness at auto until I get home, when I change it to 19% (because I can't seem to get the slider to hit exactly 20% on the dazzle widget lol)
occationally, I'll charge at my desk or on the way home, but those are the exceptions, on days when I'm using the phone heavily
biggest thing Ive found to help my battery is system panel - helped me identify a number of rogue apps using cpu and sucking my battery dry.
no screenshots.
and just so you know, you can probably find all of this info by searching and going through the threads. There are a ton of battery threads already.
edit - heyhey this is my 600th post!

Battery life is horrible..just horrible

after getting 2.1 update..my phones battery life has become more horrible.
when i am out clubbing, phone doesnt even last 8 hours.
most friends with Blackberries keep their 3G switched on always so they can use whatsapp or BBM
but for me..if i keep 3G on..the battery wont last for few hours..
how are you guys dealing with this problem?
i am thinkin of buying an extra battery and keeping it in my pocket when out.
or thinkin of upgrading to some other android phone with froyo

My phone is lasting 2 days now.. I did find a few things that were killing my battery though (Handscent bug on unread text messages, some self updating widgets I was using.. ).. suggest you try to suss out what's preventing the phone from sleeping and ditch the app, or replace with one that doesn't cause the problems...
(I've also rooted, enabled JIT, removed Timescape and a few of the other std apps too but don't really think that any of that made much difference to my battery)

Using custom rom (2.1 b005 ; i know old, but good ) with a task killer and extended controls (app) for de-/activating APNs
Also using setcpu set to poversave, max 512 and min the lowest
Loosing 1% battery in ~3-4 hours

1% in 3-4 hours ..u mean standby time?
standby time is pretty decent by default anyway
but usage time is very very low.

Disable face recognition service. I get ~3-4 days of light usage now and can do a full day at heavy usage no problem.

i'm losing 3% an hour on standby and i have nothing running, how do you guys last 1-2 days?

that looks like you have such a lot of battery draining apps.
do this:
charge the phone all the night and in the morning turn it off.
instead of turning it on with the power button, press the MENU button and the power button both at the same time.
after you see the sony ericcson logo release the power button, keep the MENU button pressed until the phone boots up
now you are in safe mode
in this mode all your start-up apps won't boot, only the needed by the system.
Keep this way all day long and by the night check your battery indicator, if it is way too much diferent than before, blame your apps.
Also remove timescape, this will give you around 15% more of battery life.
btw: make a shorcut on the homescree of your whatsapp and everything you need to stay communicated, because they won't be on the apps drawer

Custom b006 is also great at battery life. I have 3g always enabled and connect a lot to wifi at home and my battery is at about 60% after a full day of usage.
Another tip, if you want to stick with original firmware, you could try data on demand. This enables mobile data connection only when screen is on and saves you a lot of battery.
Sent from custom AOSP 2.1 using XDA App

Battery life has been greatly improved in 2.1 so I would be checking what apps you've installed because it's more than likely due to one.

If you don't use/configure Timescape, it doesn't take battery life. No need to uninstall. I haven't, and I can get two days, with plenty of usage.
I've found, though, if you reboot the phone after giving it a full charge, it tends to work a lot better. Yesterday, after using the phone for a few hours at/after work, I was at 70%. Played Angry Birds for 30 minutes, brought it down to 60%, and it was 56% by bed time.

I don't know how you guys are getting 2 days or more... for me, I'm struggling to get through the 24 hour period !!
Between, I don't like to turn off the data or stop syncing this and that sort of things. Stopping these to save on the battery, must get a old Nokia phone which can last a week without a charge.
Give any real advice other than this if possible.

Did u check whether ur battery usage have high "cell standby" consumption? I know mine has bloody high 40%...believe this is one of the culprit...
Compared with wife's x10 mini...hers superb battery life easily 3 days normal use..with 0% cell standby...argh..
Sent from my X10i using XDA App

I've said it before... Bad apps or bad widgets cause the battery to drain when on standby..
If you are getting substantial drain when your not using the phone then it's bad apps or bad widgets preventing your phone from sleeping.. when sleeping (even with wifi/ 2G/ 3G and syncing switched ON) you should be seeing between 1-3% per hour depending on how much you have syncing.
I've got FB syncing, auto sync on google sync (contacts, calendar), and googlemail push all on, all the time.
You need to work out what's at fault and find an alternative which doesn't cause the problems.

Also when you just updated your phone is doing all kind of stuff in the background. After a few days it is much better already, my phone last now for 2 days without any task killing application, but I did remove a lot of useless default crap using titanium backup application...

when i'm using it i got max 4-5 hours my phone like airplane drinking battery but when used custom roms is better
Sent from my X10i using the XDA mobile application powered by Tapatalk

my x10 was stay for 2-2.5 days .
after using BB charger it stays 20 hours .
even when i back with the original charger it stays worse than before

I habe 3G always on and my Phone lasts 2-3 Days

Hmm without 3G / Data enabled I can use my phone for 3 to 5 days because I only use them when I needed it only. My friends have it enabled everytime and he gets about 1 days and a half in quite poor reception area, maybe other setting also affect battey life? because I think the x10 battery life is comparable to my previous nokia e52 with 1500 mAh battery in similar condition (3g / data and gps active only when needed).

Battery time on 2.1
Hello i'm a x10 owner and after the upgrade at 2.1 mi battery time is more than awful around 1,5 days on 1.6 i have the battery up to minimum 3 days, i use advanced tak killer on 1.6 i had es task killer (much better than advanced task) but on 2.1 if i select kill all it turnes of my signal and my sd card and if i select kill when scren off when i'm in a call and the scren goes of bye bye signal and convesation ( what to do??????????????????????????????
And a anoyng thing i have many aplications that run by themselfs like yahoo messenger & mail, youtube, gesture search, and 2or3 more the question is whyyy? I never touch them and they are running i think thats why my battery dies so quick please helppp, i was weryyyy happy with my battery time on 1.6 now i hate 2.1 (

its not recommended to use a task killer on 2.1 as it has better task management

Juice Defender and Battery enhancing applications

Any positive reviews with Juice Defender ? I had it on my phone and used it on the extreme settings but didn't notice any difference even though it say it has improved my battery life by 1.68 times.
How do you make it really work ? Any tweaks and suggestions are welcome.
PS: Are there are more battery boosting applications out there that enhance the battery life ?

Is there any battery life boosting app that works?
I don't believe all the hype.. It runs in the background, so the apps itself is a battery drainer..
Sorry, but for me, lowering brightness, turning off 3g and mobile network when unused and also turning off haptic feedback helps increasing my battery's charge..

Of course these apps work. They turn off all radios when the screen is off, so, of course, they save battery.
Have you used this baby with radios enabled and the screen off? It gushes battery. With Juicedefender it looses very little battery when you're not using it (I should point out that the app will occasionally switch on the radio to get updates).
I recommend that you let JD manage your data and wi fi connections. It will intelligently use the radio that best saves battery. After some training, its like magic (it trains itself).
I've used several battery savers and I like Juicedefender best. It permits you to actually use the phone without disabling every damn facility and still get a day of use out of it.

Tried it once but use Green Power Battery Saver now, much prefer the easier UI
If rooted, along with LeeDrOiD 1.5.0 my battery life is amazing

I turn off wifi when I'm not using it, but 3g is too much hassle and I suppose I do struggle to get much more than 24 hours out of a single charge but gushing battery?

I think the phone does this without the help of additional apps. I'm losing only 1% per hour on standby with 3g enabled and auto sync. I did nothing special to the phone and I have no "battery saving" app. Does it, practically anyway, get any better?

You get 100 hours out of this phone with 3G enabled and auto-syncing Facebook, Twitter, etc? You must have got one out of that batch of super-phones that HTC accidentally produced.

I'm trying green power at the mo.

What settings do you use for green power?
Mine settings:
Managing wifi and mobile network
checking traffic (0,1kB/s)
Starting at boot
Day Mode:
07:00 - 22:00
On 10min - Off 10min
On if power ON
On if screen unlocked
Night mode:
22:00-07:00
On 1min-Off 8h
On if power ON
On if screen unlocked

I don't see the need to use stuff like this. I unplugged mine this morning and I still have 85% left with some moderate use with Facebook on push, weather and e-mail on 1 hour and others on once a day or update when opened.
I should point out I am using the Cingular radio and Android Revolution HD 2.0.9 but even when I was on stock I didn't have a terrible drain unless I had HTC Sense syncing away to itself. That seems to be the key issue.

I'm using the premium one though so there is a few extra settings. It definitely works though.

You may be missing the "on standby" part of my post that refers to the one made by another poster. The point is, I think the phone already disabled unneeded functions without the need for an app. My phone doesn't have unbelievable battery life, but it doesn't suck either.
Anyways, I think "battery saving" apps just end up using more power.
Cheers from my DHD.

I have dissconnected phone from computer on Sunday 7 pm. Started Juice defender. About three hours of reading comics, about 30 minutes phone calls, email few times a day and some internet/market (about 1/1.5 hours) and on Tuesday, 2 pm, I still have 34% battery. There was some music playing for about an hour and video clips for same time. Great result in my opinion. I think Juice defender works great. At least very good.

JD is alright, its not stellar but it does help (for me and my settings and usage). It will help a lot better if you purchase Ultimate Juice, that's when it starts to be interesting but that's the thing, you'd have to purchase it before you discover if its the best solution for you.
I don't think there's one app that will universally make our battery life better. The apps will help if you could make its functions play well with your settings and style of usage. Short of saying that if you find an app that will enhance your battery saving habits and capitalize on the opportunities that your phone can save power, then that'll be the best option for you...
JD is alright, UJ makes it a lot better...

It looks like it is better solution then buying extra bettery. Good job. I am gonna try it for some more time and if the effect will be the same I will get the UJ. Thanks.

No, I didn't miss that part. This phone does not drain at 1% per hour with 3G and syncing enabled - in standby or not in standby. It just doesn't. And there are newbies reading this forum who might believe your figures.

It does. I sleep for 8 hours, I lose 8%. I think its supports the argument that the phone only uses resources when needed. Since it doesnt sync the entire time and only when its scheduled to, I dont see this is as an impossible figure.
Lets try to remember the context comments are presented in this thread.

Android Assistant 2.2
Hi all, I would like just let you know, I tried a lot of apps for improving battery life, incl. Juice defender, and I must say the best one I tried is Android Assistant 2.2 build 15, after few settings I can say is really the best : full auto sync on gmail + company mail + weather, screen on 10%, screen off after 30s, gsm only, mobile data always-on, playing tank hero and few more games couple times a day, phone calls 30 - 45 minutes per day, 10 - 15 text per day, GTalk always on - and using quite a lot, wifi is on from 7.00 pm till 12.00 am, vibration always on, and result Full 2 days without any problems and overnight no any limitations, if I am using limitations overnight and not playing so much, and no wifi, battery will make easy 3 full days...

Battery Obsession

What is wrong with almost everyone's obsession regarding battery life??
Oh my gosh I'm so tired of hearing everyone saying: I have switched everything off now and still only get 2 days of use.. Why??
If you want a weeks worth of battery life get 1" non-touch black & white screen phone.
If you want a awesome phone get a Galaxy Note, switch everything on, sync your social networks and mail every 10 minutes. Browse the web on the awesome 5.3" screen, play games and enjoy the phone to the full. So what if you need to charge it every 12hours.

2 days 10 hours with light usage (1 hour screen on time, automatic brightness, few 5 minute calls, about 20 notes, apps updating and some browsing over wifi) and still have 70% left.
It depends on the user. It surely has the juice to cope with heavy use. I couldn't be more happy

Roger that, entering good guy Greg mode.
First of all, the fist charges are important. Once i bought it, i updated it to latest 2.3.6 OTA and started using it till it shut itself off. Then charged it to full while off. Repeated this circle 5-6 times, maybe more. I haven't rooted the device yet. Its 100% stock running KK5. (Europe)
As i am in places where there is wifi available, i switched data off. In wireless and network options, i use "GSM only" mode. I left auto synch, auto brightness and gps on.
Widgets. I use the stock weather, stock digital clock, battery solo widget, stock task killer, stock news and weather, stock calendar. All those spread across 6 homescreens with 39 other app shortcuts on a black/silver background.
About the light usage. 5-6 times a day, i switch wifi on for synching. I read my mail and check my Facebook messages. Once i am done doing whatever i wanted to do that requires internet (update any app that requires updating etc.), i switch wifi off.
Lastly, before going to sleep, i close all active apps using the stock task killing widget and clear the ram. Overnight, i lose 2% battery.

Now that's what I call a battery obsession!
I just use my device as I see fit, and top up charge when I can - I have a Micro USB cable on my keyring, which means I've always got a charging cable on me.
Regards,
Dave

I partly agree with you. But we lack the battery technology to do all that. Not having enough signal coverage alone is enough to drain your battery. In some ways, you adjust yourself so as to keep using the phone for longer periods of time.
I must disagree with the fact that all the above i mentioned are garbage though. I am happy that i figured out a combination that will save me huge amounts of battery. I can still do all the heavy use i need, when i need it. With smart-phones there are options in settings to let you do just that. No-one forces you to do all that, just as no-one forces me to leave everything on.
Having lost 30% battery in 2+ days, means that theoretically if i kept using it like that i would get 7 days of one charge. For example, i know when i will receive an email, from who and when he/she expects me to reply. I hardly get any emails that require immediate response. If someone expects me to reply instantly, they send an sms, or call. Both of the options work fine using gsm only mode.
I also don't find important being logged in facebook 24/7. I 'll log when i have a break, before sleeping and when i wake up. Need to check the weather before leaving for work? Tap on wifi, wait 2 secs for it to connect, click refresh on the widget, done. It doesn't take more than 10 seconds.
I don't rush to turn off wifi or anything. I just use the battery juice and the phone's cpu on demand. The note is indeed a smart-phone, but with all it's features it is reaching laptop territory. I find that treating it as a laptop works better for my needs. Then again, thats just me. If your lifestyle demands all of the note's features on 24/7, then by all means leave them on. There are external 18000 mAh battery packs you can grab.

I'm running Cassies's Lite ROM and I can get between 5 hours and one week on a single charge. Just do everybody a favor and understand that this thing can go into sleep state for days.
If I leave it alone, nothing playing or syncing on the background I lose about 1-2% in 8 hours, so this could go on for days, even a week if you don't touch it.
Of course if the screen is on for only 15 minutes on 2 days, you're not going to have much power used.
During calls screen is off, yesterday I did a 1 hour call and lost less than 10% battery. So you can make several calls on 2 days and lose litlle charge.
If you play a 3D game with screen on at full brightnees, you'll deplete the battery in 5 hours.
It's no difficult to understand. battery life depends on what you do with the thing. Whenever the screen is on, it will consume power. How much depends on the brightness level and the color of the pixels displayed.
Syncing facebook / twitter / e-mail through 3G takes a lot of power too, specially when you're on a low signal area.

Anybody noticed the difference charging the phone while off versus charging it while on.
It looks to me charging while off makes the phone battery last much longer
it also takes much longer time to charge

Yes thats a fact, it also happens with my girlfriend's galaxy s2.. With my note the other day, found out that even plugged by usb to the pc with intensive using, wasn't enough to charge the battery % and actually it was decreasing..

My old iPhone 4 did that . I was downloading an app while having it plugged in into the wall outlet, and the battery just started going down (600+ meg download).
The note is a sloooowww charging device, that's for sure.

i always get over 2 days life out of mine. i never use wifi and i have gps on all the time. But what i do is i have the screen to auto and i use the stock task manager widget. With applications i always use the back button instead of home which 90% of the time closes the app. As a browser i use opera mobile as this has an exit button too. keeping running apps to a minimum seems to help my battery las well.

I'm getting amazing battery life.
And still going strong 11hrs with somewhat light usage and it's nowhere near 50% battery yet hehehe

i can get around 5 hours display time, wich is faaaaar better than sgs2. During the night the power consumption is 1% per 5 hours with wireless off or 1%/hour with wireless on. I'm on Rocket rom v12 which rocks!

I see things like this and I cringe... It's a smartphone. It shouldn't need all this garbage done to it to get good battery life. It shouldn't need toggling, everything should be on, push notifications should be used, and it should still get good battery life

I'm getting 3.5 days on a charge with moderate use.
I have 4 email accounts that are polled every 60 minutes.
I make a few calls a day and use the browser a little.
What seems to help is doing a force stop on apps that I'm not using like AP Mobile and Yahoo Finance.
Also, I am runnning KL7.

With light usage, few sync's a few calls ((4-5 min) some texts and notes and few minutes of gaming.. I get a around with 16+ hours of usage easily. I'm happy with the battery and the Note can definitely get on with a more aggressive battery usage...

I need major battery saving tips!!!

Nuff Said

Dunno' about you, but after an year I started noticing the battery isn't as good as back then.
Try JuiceDefender, that's what I'm using right now and it's quite good.

Doesnt that waste more battery?
Cause it runs in the background?
Not really sure, but thats what i think.

I vote JuiceDefender as well. It has very minor battery impact for a decent amount saved (as long as the phone's on standby and not syncing a lot). You don't state what you've already tried, but with root & unlocked bootloader you can underclock and undervolt which helps save battery a lot. Delete unneeded apps, especially the stock crud. Make sure no apps are using partial wake locks (keeping the phone from going into deep sleep) by using BetterBatteryStats. Btw, BetterBatteryStats can identify a lot of things that might be draining your battery. Of course, the most obvious battery savers would be turning brightness down, turning off GPS, turning off WiFi, lowering volume, etc.

Auto Brightness on or off ?

Really? Xperia Play's been the only Android device I've ever owned where battery life WASN'T a concern.
...at any rate... here's some tips!
• Toggle Data to "Off" when it's not needed or switch to 2G/EDGE (or even Airplane Mode for dedicated gaming sessions)
• Enable Auto-Brightness
• Disable the notifications in any app that keeps your phone in a data retrieving cycle (Facebook, Twitter, Skype, Weather, etc)
• Keep GPS/Location Data off whenever possible
• Stay away from process heavy battery destroying whores like Regina Launcher, GoLauncher, Xperia Home, Fullscreen Launcher and Claystone
• Use a minimalistic launcher (LauncherPro, Smart Launcher, Lightning Launcher, ssLauncher)
• If you like live wallpapers, that's fine - but fine-tune their options so that they aren't always murdering your battery
• Make sure your WiFi connection is set to disable mobile data (this is commonly set by default)
• Be very wise about your widget usage. If you're going to use them, fine-tune their settings so that they don't murder your battery
• Give your phone a complete battery drain, then recharge fully at least once every month.
• If you're in low-reception areas that have WiFi, save your phone a lot of battery-draining connection conflicts by keeping WiFi on.

I'm using almost everything TLR suggested plus set CPU with a profile for screen off that turns the CPU down to 340mhz. Battery seems to last pretty decent for me.

TLR brightness option is diff than mine, instead of auto bright i just simply put it as low as possible. It totally savs more.

Im using a Mugen 1800 battery . Bought it last week and i easily get 20-40% more charge than with the standard one.
It lasted me for full 2 days of light usage (2 hours and 30 minutes of display time) .

Tried nearly everything on this page.BUT, does OC waste alot of battery??

Overclocking would make your battery worse. I don't know if it has a major effect though, depends what you overclock it to.

How much battery time are you getting now?
My advice, go back to 100% stock factory reset.
Then debloat.
If your phone is old, your battery probably lost some of its capacity, so you could try a new battery.

My battery is fine now, tried all the tips and made massive difference. Thanks everyone!!

I don't know if battery is different here in Aus (BST41-1500mAh), but mine is 18 months old and just by turning off bluetooth and WiFi and controlling screen brightness and 3G as i need them, i got 2 days general use (10 calls per day 50 sms and 1hr 3G web browsing per day) R800i.
Last month i flashed JellyBean following these instructions: http://forum.xda-developers.com/showthread.php?t=1801983 and now I get 3-4 days use! With this mod I can leave it in 2G mode and for some reason it still gets data via EDGE so I can still get facebook + skype messages etc. This feature and i'm guessing better control of the CPU and tasks are obviously the main reasons for better life

I would really like that rom but i need camera.
