Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.

I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.

Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:

http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea

I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
[myTouch 4G General] ags29:
Maybe. All I know is my battery increased dramatically after running that app once.

I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.

Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.
[myTouch 4G General] rosebud1:
How long does 1 of those batteries last?
[myTouch 4G General] erickdj:
simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.
[myTouch 4G General] iambryantho:
does the royal ginger gets the same battery result?
[myTouch 4G General] erickdj:
Better than what's reported under CM7. The battery life I posted above was on RG.
[myTouch 4G General] danyune:
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?

To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken

I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps

For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage
[myTouch 4G General] sundayhustler:
Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
[myTouch 4G General] sundayhustler:
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.
[myTouch 4G General] sunsean:
At the end of the day, about to charge, and I'm at 6% battery left, been on 15h 40m 28s, and screen has been on 2h 27m 23s, and used 11%. This is the best battery life I've had since getting the phone, and I think it's all due to switching from stock to cm7. It's really almost double what I was getting earlier. Usage was moderate, browsing, about 45-50 minutes of listening to music, about 30 minutes of word mix, about 5 minutes of maps with gps, a couple short phone calls, several texts (incoming and outgoing), some google talk, and a little bit of customization/playing with phone. Oh, and this is with automatic brightness, so I can only imagine how much better it'd be with lower brightness setting.
[myTouch 4G General] NeverAlwaysEver:
This is my latest battery performance after calibrating with battery calibration app and it has been consistent. 20% left after 1 Day 15 hours 34 mins since unplugged, 2 1/2 hours display on, light data, avg text and talk, Pro Evolution Soccer game 54 mins (this is a heck of a game), Music through earphone on poweramp app at least 1 1/2 hours, Pandora music on phone speaker 30mins, 4g on always and Wifi on 8 hrs. Setcpu max 1401/ min 576 smartass, the rest of my phone stats are in my signature. I am sure ROM and kernel has to do with battery performance also. And as you can see in the pics I just took now.
[myTouch 4G General] sunsean:
Wow, that's pretty impressive. I've heard Royal offers better battery life than cm7, and based on your results that seems true...may have to flash over to check it out.
[myTouch 4G General] NeverAlwaysEver:
Yes Royal Glacier is great on battery and performance with all the sense features
[myTouch 4G General] chipmaniac:
My Experience

I get from 17 to 25 hours on a charge using CM7 with moderate use. Currently I've been off the charger 7.5 hours and I am at 84%. I've had the display on for 50 minutes.

The changes I've made that seem to help:

1. Turn off Wi-Fi when not in use

2. Turn on Wi-Fi whenever a connection is available. This is huge. It takes a lot less transmission power to reach your router than it does a cell tower, especially in 3G/4G.

3. Set the data connection to Edge when I'm not actively using the Web on the device and not on Wi-Fi. It only takes several seconds to switch back to 3G/4G when I need speed.

4. I use SetCPU to set my processor to the minimum when the screen is off.

It's notable that I don't turn off data sync or selectively disable sync in apps. To me, having your apps sync in the background is even more important to me than having the absolute maximum battery life.

I'm doing an experiment tonight to see if having Wi-Fi calling on at home extends the battery. In theory it should so I might even break my record this charge.
[myTouch 4G General] chipmaniac:
Addendum

I'm going to have to test another day regarding the Wi-Fi calling. My three-year old got the phone and went played an Angry Birds marathon session. I still ended up with 14% after 19 hours with my screen on 3h45m.
[myTouch 4G General] AndrewAD3:
Thanks for the tips.
[myTouch 4G General] sabo2000:
Carry a battery charger! Sorry, had too..... :D

I flash a new ROM at least 5 times a week, I can not keep up, though one of my backups is CM7 and I never worry about battery on CyanogenMod ROMs.

Though when I have really tried to track it it was about 17 hours and still had about 15% battery life (On CM7). Currently I am on Rafy's 3.0 Port/ROM and today I had 30% life before I plugged in and was up for around 12 hours.
[myTouch 4G General] iambryantho:
been using royal ginger 1.6 and i got 16hr at 11percent. with 4hr 16min display. used gps for 15min, music for 40min, phone 30min. no wifi
[myTouch 4G General] sunsean:
Been running evil's 3.0 rom the last few days, and have been getting surprisingly good battery life...easily going all day (about 14-16 hours) so far. And that's with auto-brightness.

Also - I picked up a great deal - 2 batteries and an external charger for $30, so now I'm not so concerned with getting that extra hour or two with all the tweaking...I use the phone freely (i.e. auto-brightness, 4g, background sync/data) and just make sure I've got an extra battery with me, in case.

Hi there, to those who have one, how much of the internal 16gigs is available for app installs? 1gig or 2gigs?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Zach Alt:
Like 14gigs. Whatever the OS doesn't take up.
[Eee Pad Transformer Q&A, Help & Troubleshooting] nxt:
Are you sure? There are no Android phones that can do that.

Galaxy S, Nexus S, etc..etc.. all have 16gigs or more "internal memory"

but only 1 or 2 gigs of it is available for the system for APP INSTALLS and the rest is partitioned out as an "internal external sd".
[Eee Pad Transformer Q&A, Help & Troubleshooting] Zach Alt:
I know. It's new for 3.0
[Eee Pad Transformer Q&A, Help & Troubleshooting] tineras:
That's awesome news. I was a little worried about ordering the 16GB model, but I will just leave that space for apps and put all of my music, movies, pictures, etc. on the external card. Now I just need to find a decent micro SD card that is supported by the Transformer.
[Eee Pad Transformer Q&A, Help & Troubleshooting] nxt:
Cool thanks.

Transformer will be my first Honeycomb.

Can you still mount this to your PC and copy stuff to it?

The Tablet will still work when mounted? (Since on Android 2.3 and less, anything on the SD/Internal SD is unusable while mounted).

If so, good job Google for finally figuring it out.
[Eee Pad Transformer Q&A, Help & Troubleshooting] lacrossev:
If you use multi-mount widget or dual-mount widget the device should still be usable, just don't mount using the built in mounts while doing so.

I received my Clip case on Saturday after ordering it on the previous Wednesday. Super quick shipping and the case is very good quality. I have been enjoying being able to prop up the G Tablet. The only niggle is that the left side clip covers the door for the USB/Micro SD slot, but that's not a big deal to me.

Hardware Breakdown by t3h_g3n3r4l
[General Topics] W0rmw00d:
Hello I am a grad student looking for bugs, apps, system configurations, or anything else that drains the battery of android devices unnaturally fast (especially Motorola's DroidX, but really any Android phone). I've been reading the forums a lot already and have a good understanding of all the basic issues that will drain the battery expectedly (GPS, wifi/radio, CPU, over clocking, frequent app syncing, etc).

I am NOT looking for an app to extend battery my life or trying to keep my phone running longer. I'm looking for repeatable software/configurations/bugs (especially version numbers) of things that kill battery performance.

I'm hoping to compile these into a characteristic study that helps me and my fellow students create system tools that will help everyone automatically find and fix battery issues.

Thanks for your help.

[General Topics] ladclothing:
basically just having a lot of widgets on your screens or even having tasks running will drain battery. I've noticed htc phones have the worst problem with battery cause they run off of sense UI and that takes more battery then lets say the droid x running off of the moto UI
[General Topics] ericatomars23:
There are alot of things that can and will drain your battery. Your screen brightness to high, especially since these newer phones have fancier screens that look great but kill the battery, as well as lighter, white wallpaper will also kill your battery.

Apps that will kill a battery fast

-Google Maps

-ESPN Sports center

-All kinds of games

-You Tube

-your browser

-Certain Livewallpapers

By USB support do you mean support for mass storage protocol? (I.e. the device showing up as a disk on a computer.)

Or do you mean USB support for peripherals such as keyboards, mice, and portable drives.
[Xoom General] novaIS350:
-Improved Flash support in the stock browser

-Cloud music/movie service

-Netflix app

-HBO Go app

-Native Google Docs app

-Google video chat support for tablets to phones.

-Improved enterprise support. (Xoom doesn't play nice with Gannett/USA Today's network)

-dedicated HD movie trailers section in Youtube. Similar to Apple.com/trailers.

-Mouse support <-- this would be flipping awesome.

Netflix and hbo go are not just apps. There are a lot of DRM related issues that could be addressed in updates. What I mean by 'doesn't play nice' is that simply isn't a supported device.

Something I've noticed in my phone, the camera app runs kind of slow.

It didn't use to happen, but almost a week go I noticed the camera took too long to load (I count 6 or 7 seconds) and picture gets stuck for a moment when focus is adjusted or the options button (the one on the bottom right corner) is pressed. Has anyone had a problem like this? I tried hard resetting, but no dice.

If it's important, it happened around the time I tried Android on the phone trough SD card.
[HD2 General] iamnotarobot:
I happened to find a solution to it. In case someone ever has the same issue, it's resolved by formatting the SD Card or by saving the pictures in the main memory. It's so simple.

If anyone has tried it, how did you get on with it? And also if someone can extract the myfiles.apk file from their system/app directory on a deodexed JVB and post it, I'd love to give it a try.

Using CM7, somehow I feel there is something wrong with this phone itself... will see what happens when t-mo gets the phone back for repair...
[G2 and Desire Z General] I AM VS4:
Well the iPhone 4 does not allow you to change features that alter the battery life too much like the HTC Desire Z. The iPhone 4 uses a stronger battery that allows the iPhone to reach a maximum of about 36 hours. HTC Desire Z's battery life all depends on use but this phone could last about the same with moderate use. Hope I helped :)
[G2 and Desire Z General] lil-devil:
well mine last around 14 hours with minimum use using the OEM battery....

wondering if changing to the 1800mAh battery would help

but it really seems like that battery life just sucks
[G2 and Desire Z General] creativedevil:
I don't know if the battery life really sucks or not... When I don't just touch the phone, it lasts atleast 2 days and more... but as soon as I start using it, well... battery just want juice all the time...

Changing to 1800mAH will certainly help as it is bigger and as some of those who have experienced, it certainly lasts somewhere around 40-50 hours.

As a note, I have even tried the Battery calibrator app, can't really say if it helped.
