Which Andriod phone has good battery life? And how do they compare with iphone or Nokia's

i can last for 4days,very light user here.most of the time i put on the table...

APN off?
Even leaving it overnight (finish charging at 12am) and wake up at 8pm, battery already drop 10-15%. Didnt even touch it.

My Desire usually only last about 8 hours lol, sad. But after installing Juice Defender, seems to be able to go to 16 hours or more now.

how does the juice defender work in saving battery?

Cool tips cleave.

Btw how do you wipe battery stats?

Ok, so I bump charge my battery and it's performing better now. 
After the bump charge, I did some extreme battery draining activities just to test it out:-
1) downloaded 157MB of data through Wi-Fi for the Let's Golf game (it's currently free from Gameloft, BTW)
2) Played a couple rounds of golf.
3) Updating facebook, crusing round the forums with Tapatalk.
4) Sent a couple of emails
5) Trying out the new ADW launcher themes.
6) Made and answered a couple of calls and SMS (normal day-to-day usage)

Around the 12th hour, I still had 63% left on my battery. A full 24-hours and it was at 42%. This is just amazing. When I first used FroYo, the phone would never lasted that long. I'd say without me 'going to town on WiFi and playing 3D games' the battery should last like 2days or more.

Anyways, here's how you bump charge your battery with battery calibration steps embedded. If you're not rooted and have no way of wiping the battery stats, I suppose you can just ignore the step. 

1.) Connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged (use OS Monitor to make sure its at 100%.)
2.) Disconnect the phone from the charger, and power it off.
3.) Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
4.) Disconnect the phone from the charger and power it on and wipe battery stats, then reboot.
5.) Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green for a minimum of 30-60 minutes.
6.) Disconnect the phone, power it on, and use it.

Here are a couple of things to note on my phone setup. They may or may not affect my battery performance results:-
[*] I have Juicedefender running
[*] I run an undervolted kernel. A somewhat unstable one I might add. I grabbed a nightly build from intersectRaven's file dump before realizing that he hasnt officially released it yet. And I'm kinda lazy to re-flash a stable kernel. 

if want to use the method need to root?

I understand your concern regarding battery life on your Nexus One device. The following steps should significantly extend the battery life on your phone. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged. Disconnect the phone from the charger, and power it off. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green. Disconnect the phone, power it on, and use it. You need to use this sequence only once. If the issue of battery life on our phone persists, I recommend you contact our HTC accessory department directly, by dialing 1-888-716-3594. Their business hours are Monday to Friday 8:00 AM – 8:00 PM Eastern Time...

I see. Will do this immediately after got my Desire in 2days. Thanks!

EDIT : need to do this only once right?

Thx for sharing cleave , will give a try today ..
Wonder if it can be practice on WM HTC like TD2 ?

I suppose so since it was engineered by HTC.

Not sure it's just me or the method is strange

I tried step 3 and step 5 - but it immediately went to green although the power is off... does it mean my phone battery is Ok and no bump charging required?

from what i read, i dont need to do this if i just bought my Desire? whats the rules to do this bumping anyway?

I guess if you're satisfied with your battery life, you wont need to use it. 

I suppose so since it was engineered by HTC. 

I see. but lets say i'm satisfied, will this bumping helps my battery goes longer?

That depends on your setup like how many widgets are you using, do you have live wallpaper on etc. An indication that you may need to bump charge your battery is when all of a sudden you feel that the battery life gets shorter even though you're using your phone normally. Let's say that you normally get 1.5 day, out of the blue it dropped to 0.5 day. Your battery then either needs to be recalibrated or it is physically damaged. A total recalibration would be to discharge the battery totally, partial charge, wipe the battery stats and recharge it to full power. But that would need a root permission or some crazy looking adb commands (at least to those outside the Linux world), so HTC came up with this bump charging method that is more suitable for all users (with or without rooted device).

Anyways, EVO 4G is an awesome phone but with a terrible battery life (as reported by its users). Here's a post detailing how to fix it. There are probably some tips in there that may apply to other HTC sets:-

Another unproven myth is that task killers can improve battery life. This has been debated in countless occasions. Do task killers really help? Or is it just a placebo effect? Does it do more harm than good? Here are some good threads on the issue, read them if you have the time and you decide:-

I used task killer on my 1.5 Hero. It did help in releasing memory and maybe prolonging the battery life a bit. But since going to 2.1, I didnt see any difference using a task killer in terms of battery life. In fact, on Eclair, I found that my phone was lagging whenever I have the task killer on. So, I abandoned it. On FroYo, task killer is made more redundant as FroYo's memory management is just fantastic. You'll get twice as much free memory than on Eclair.

im getting this in adb .. where did i go wrong?
exec '/system/bin/sh' failed: No such file or directory (2) -
i really am not quite sure how to type it in adb btw.. any guides?

I assume you're in Recovery. Did you mount the filesystem?  

i guess no..
update :

C:\androidkit\android-sdk-windows\tools>adb shell
~ # rm /data/system/batterystats.bin
rm /data/system/batterystats.bin
thats what i guess after entering rm /data/system/batterystats.bin.. it showed up back rm /data/system/batterystats.bin without saying anything else.. is it correct?

ummm... yes. you can ls the directory to reconfirm. 
Actually the safe way to do it is to mv the file to some other place and later if things get screwed up, you can always un-mv the step. But WTH. 

yup. if there .bin file wasnt there and you try to rm it, you'll get an error message. An echo would mean that the command was successful.

BTW when I wrote about how to manually wipe the battery stats, I was doing it hypothetically. I wasnt expecting someone would actually attempt it. 

thanks.. got it.. i did it 3 times btw.. did once, rebooted then did it again and one more time again.. haha.. just to make sure that the echo was a success like output.. u should have known that once a guide posted, there would be itchy hands to try.. lol.. u should always post any disclaimer next time or sumone will hunt u down in case anything goes wrong.. kiddin.. thanks again btw

owh.. i did realized that bump charging and clearing the batt stats dosent do much on mine.. it does went back to green after a few minutes only.. seems like it is showing that i charged to full capacity ait?

If you charge it during off state and it straight away go green, it is at full capacity. Anyways, if you want a more detailed report on how your battery is faring, go to the Market and look for 'OS Monitor'. If you go to the 'Misc' tab you'll see some info about the battery. If you see 4000mV and you're around 90% capacity or more. Then the battery is fine, generally speaking.

Here's the good part though, something that can measure whether bump charging will have any effect on your batt. Go to the 'Message' tab and click the 'menu' button on your phone. Choose 'Option' from the pop-up menu and scroll down until you see the 'Message' section. In the 'View Log' option choose 'dmesg'. Tap 'Filter dmesg', check 'Enable Filtering', tap 'Tag Filter' and type 'batt' in the text box. Get out from the 'Options' (press 'back' a couple of times) to the 'Message' tab. You'll now see a more detailed stats of the battery condition, including the rate of it discharging. Apply some common sense here, a Desire/Nexus battery is 1400mA (it's actually more but HTC rounds the figure). So if your condition is at 100% and you see the reading is below 1400mAh (like 1300mAh or something worse), then you'll need to bump charge it and reset the battery stats as it is obviously giving the wrong reading. Some guys on XDA managed to get it up to 1480mAh through bump charging. That mAh is actually an indicator on how much juice your battery has. The more, the better.

Im charging it now and observing the figures. Seems like it is 100% at 1377mAh for 10minutes ago. Now it is still increasing and ill monitor it until it stops and ill try to wipe the batt stats once its not increasing anymore

update : sigh.. system detects it as full at 1363 actually.. it says batterycharge stop 1363mAh.. im trying to follow the bumping steps all over again.. seems like i did it wrong previously.. now its charging during off with the green LED not appearing yet.. seems like trying to charge to full i guess..
btw Cleave, u mentioned ur running an undervolted kernel. Mind telling what is ur clockspeed that u set in SetCPU? Ive been running my desire at 1113 and psxdroid seems sluggish a bit when i underclocked it to a lower clock. I know that im draining the battery so much but i really wanna hear what is the speed others have set in CPU for their daily tasks. Btw, I really dont want my agumon to be running slow or not it wont digivolve into a metalgreymon soon.. lol

how come i dont see my battery capacity after i do that? 
all i see is
active wake lock ds2784-battery ?

just got my Desire 2 hours ago. can i do the bump charging straight away? the lady said i need to charge for 8 hours first, can this be counted as first step?

Ah, the old 8 hour-charge myth. That only applies to dinosaur age Ni Cad batteries not the current Li Po batteries. Years and years of misinformation by those vendors and nothing has changed  What I do is charge (untill it fully charges or 2.5hrs-max is fine) and discharge the battery fully for the first 4-5 usage cycles to condition the battery so that the phone can read the battery level accurately. After that you can bump it or just charge your battery as often as you can which will improve the battery life (tip for X10 from Sony Ericsson). I have my usb charger at work and a cigarette charger in the car which I plug in all the time so I never have to worry about battery life

nope!

I need to ask, where's this message tab you speak of?    I literally went to my message app LOL

Which Andriod phone has good battery life? And how do they compare with iphone or Nokia's

well, iPhones Battery Drains very fast, i use an iphone, but when u upgrade the latest firmware the battery life increases and becomes a longer lasting 1 , so if ur buying an iphone, upgrade it to iOS4.0.1

haha he is actually talking about OSMonitor there.

Yeah on Eclair. So it's only for froyo?

yeah and at least some of htc phones can do the bump charging, meaning much more better after that.

It works on Eclair too as it is more to hardware than software. Just that the dmesg batt output on Eclair is raw and a hassle to read, unlike Froyo where it is formatted to display in units (mAh and mV). I guess I'll snoop around my old Hero and see if I can come up with a way to translate those weird numbers to comprehensible figure.
And we can swap batteries too. 
While iPhones can only rely on software updates to improve its battery life, Androids have wider options for the task. We can do it through software (e.g undervolting the kernel) or hardware (e.g buying extra battery).

What kernel are you using for that ROM? is it a .32? 
Can you do this through ABD? :-
adb shell
? dmesg | grep -i batt

Please show me the output.

i mean the charging, turn off, on, off and min 30-60 minutes dont need to re-do right?

I've done active surfing for that past hour and my X10 battery is still 100%. WTF?

Complete Guide to Maximizing Your Android Phone’s Battery Life

You’re no doubt reading this article because you’ve got a new Android phone, but there’s just one problem: that the battery runs out on a daily basis. Instead of putting the phone down, let’s maximize the battery life.

Saving your battery life isn’t rocket science—the general principle is to get rid of the things that are draining the battery the most, and trim down other things that you need to use, but maybe can tweak a little. Keep reading for the full explanation.
Use Android’s Built-in Battery Usage Screen

There’s a screen built into Android that most casual users probably don’t even know about, and it can tell you exactly what is killing your battery. Head into Settings –> About Phone –> Battery use to see what has been killing your battery life.




From this screen, you can usually see what apps are the worst offenders, and you will probably notice that the biggest problem—at least, the biggest one that we can fix—is actually the backlight on the phone. Personally I’d prefer to talk less to other humans, but that isn’t always an option!

Note: on my phone, I’ve already configured the backlight to not be very bright—normally that number would be a lot higher.
Adjust the Backlight to be Less Bright

Since we’ve already determined that the backlight is usually the biggest problem, you should probably adjust the settings. Head into Settings –> Display –> Brightness, where you can choose to automatically adjust, which usually works fairly well, or you can just turn the brightness down to the lowest acceptable level.




You should make sure that the screen timeout value is set to turn off quickly as well.
Disable Your Wi-Fi When You Don’t Need It

Wi-Fi can really speed up accessing data on your phone, but it can also be a big drain on the battery if you don’t need it enabled, especially when you are out and about… The phone will try and scan for a wireless network even though you may not want it to.

To enable Airplane mode, you can head into Settings –> Wireless & networks–> Airplane mode.




You can easily toggle the Wi-Fi on or off with a widget or shortcut—there’s a built-in widget included in Android phones, or you can use the AnyCut or BetterCut utilities to create your own shortcuts to directly turn them on or off without requiring a widget.
Disable Bluetooth if You Don’t Use It

If you aren’t using a wireless headset, there’s no reason to have Bluetooth running all the time, and you should probably cut it off to save the battery life. If you never use it at all, head into Settings –> Wireless & networks–> Bluetooth.


You can also enable or disable the Bluetooth when you do need it, using the power widget.
Use the Power Widget to Easily Toggle GPS, Bluetooth, Wireless, and Screen Brightness

Android includes a built-in Power Widget that can easily toggle these settings on or off—just long press on the background of one of your screens, choose Widget –> Power Control to add it to the screen. You’ll notice in this example screenshot that I’ve got my GPS enabled but I’m not using Wi-Fi or Bluetooth at the moment—the icon all the way on the right lets you easily toggle the screen brightness settings.


This is probably the simplest and easiest thing that you can do to save your battery without having to dig into the settings all the time.
Disable Apps that Sync Constantly

The built-in Email application (not the Gmail one, which uses Push technology) can suck the battery badly, because it syncs on a too-regular basis, especially when you have lots of accounts—each one of them is set to sync every 15 minutes. You’d be better off setting it up to sync manually, but if you want it to sync automatically, you should set it to sync less frequently.

Open up the Email application, head to your account, and choose Account settings –> Email check frequency from the menu. Change this to something more like an hour… or never. You can always hit refresh manually when you want to read your email.



The same thing holds true for other accounts, like Twitter clients, which are even less important to update all the time. For Seesmic, you can head into Settings –> Background Updates from the main screen. For the official Twitter app, the settings are similar.



The Facebook application polls automatically in the background, and you can customize the refresh interval for that as well—if you don’t need Facebook updating all the time, you should set this value as high as possible.

From the main Facebook screen—the one with the icons—head into Settings –> Refresh interval from the menu.


Disable the GPS Location Features

One of the biggest battery sucking features on my droid is the GPS… When I have navigation going, the battery dies far too fast, so I end up having to keep it plugged in the whole time I am driving. This makes sense… but what you might not know is that a lot of other applications use the GPS as well.

You can also change the GPS to use wireless networks, and uncheck the option for Use GPS satellites—this will make the GPS a little less accurate, but it will save your battery. Note that you probably want the real GPS enabled if you’re using Google Maps Navigation.



Additionally, you should turn off the geolocation features in your Twitter client, weather application, or whatever other apps that you really don’t need them in. If you want to keep it enabled, that’s great, just realize that it does drain the battery, so uncheck this option to help.
Use a Task Manager to See What is Always Running

It is a wise decision to have a copy of Advanced Task Cleaner or a similar application installed on your phone to help you kill applications that don’t need to be running, but more so that you can see what exactly is launching itself repeatedly in the background. You can setup an auto-kill list for applications you don’t use that often—make them cut off when you shut off the screen, or after an interval.

Note: If you’ve configured your application settings to not pull down lots of data or do checking in the background, it’s not quite as important to keep tasks killed all the time—that’s really what kills your battery, not having them sitting idle.


You can also configure advanced task manager to show you CPU usage for each app, which is a more useful meter than memory usage when it comes to battery life.
Disable or Remove Applications That You Aren’t Using

Once you have identified the application that you don’t want running all the time, check in the settings to see if it can be removed from running in the background. Some applications will give you an option for notifications that can be turned off if you don’t need them, making the application not check in the background so often.

It should go without saying, but we’ll say it anyway—you should remove the apps that you don’t need anymore, especially the ones that are draining your battery as determined from the android battery panel or task manager. Head into Settings –> Applications –> Manage Applications and then you can click the Uninstall button for an app.


Disable Home Screen Widgets You Don’t Need

If you’ve got loads of widgets that are pulling data from the web, that means they are likely pulling down data in the background all the time. You should try not to go overboard with these, or remove the ones you don’t actually need.
Disable Animated Wallpaper

Yeah, that sweet animated wallpaper doesn’t help your battery any. Get rid of it for a small extra battery savings.


Use APNDroid to Kill Your Entire Data Connection When You Don’t Need It

If you’re using a phone that’s on the AT&T or T-Mobile networks, you can use the APNDroid utility to kill your data connection entirely with a simple widget. It doesn’t work on Verizon phones in my testing. It’ll disable the data but still allow regular calls and SMS.


Keep the Battery from Getting Too Hot

One of the quickest ways to kill a battery is to leave it out in the sun—try and keep your phone somewhere that isn’t too hot whenever possible. You’ll end up needing to replace the battery a lot quicker if you don’t.
Additional Notes

There’s a number of other things you can do to extend your battery life a bit—one of which is to use a rooted phone and install the Autostarts utility, which you can use to keep applications from launching themselves automatically. Since this isn’t something you can do on a stock phone, we’re not covering how to do it here.

You can also use an application called Tasker to automate certain actions, like turning on or off the GPS or Wi-Fi when you launch a particular application, or scheduling a time of day to make sure that Wi-Fi is disabled. Lifehacker has a great guide to using Tasker to automate your phone, and they also explain how to use a  configuration to scale back data usage at night.
