Settle down buddy...
Those threads weren't the same and for a very different purpose than this one.
This thread (from what I understand) is a place for people to post their setup and their actual usage figures. The ones you linked were about tweaks and optimisation which is not a comparison thread.
The first post could be updated to better reflect and standardise the way users post their figures.

If you lose 10% battery life in one hour on standby with 3-5 MaH drain, your battery might not be calibrated. Recharge it with the phone off and then delete batterystats.bin in /system/data on the next boot.

The main reason I throttled my processor down to 384 mhz to get 100-350 mah is so that I can surf the web for 5-8 hours a day without having to recharge. No noticeable lag except with animations.
Any thoughts?

I said same setup, not same battery drain.
Now I have followed all guides and my current drain is 60mA, still far away from 11mA
Share some settings?

Wifi the biggest battery killer?

So I notice that an hour on wifi surfing the web took about 20% or more of thE battery...even playing game doesn't do that to the battery. Anyone experiencing similar thing? Anyone with 3g, is data looking the battery too?

Just keeping wifi turned on is also drains the battery for me.

Check your screen luminosity.it is the biggest battery killer

I'm running the Moto234_eVo_Carbon_V0.3 build and I've noticed that even with the screen off and the phone idle my battery drains at a pretty good rate when compared to WinMo. Any fixes for this?

for me 3g/h draw much power than wifi, almost 1.5x-2x of the wifi surfing..

Screen brightness is easily the biggest batter drain keep brightness as low as possible,
Data connection will hog more than WiFi if you are in an area of weak signal and your device is constantly searching for a signal, when your at home or work using WiFi just turn data off and switch to only 2g networks, set setcpu to screen off 245 245

Screen brightness definitely hits it hard, then wifi and bluetooth, keep em off whenever you are not using them and of course apps running in the background, grab a task killer, if its not needed, it shouldnt be running or else it will use power.

Get "current widget" from the market to see how much powers are being used. While screen off, my phone only drain about 4~7 mA...

I just came across this. Super detailed analysis of battery usage.

3g draws much more power than wifi. If wifi is available use it over 3g. But like others have said, the screen is by far the biggest battery hog.

I don't see how the screen is the biggest energy hog. When I leave my phone uncharged untouched over night and it it displays 7mah on current widget, I lose 40% battery in 7 hours.

That's unusual...i lose less than 10% over night...even with bad reception in my room, that didn't kill my battery. Maybe you can try this to test it out. Fully charge before you go to sleep. The next morning, check your battery in setting to see what is using the majority of the battery drain during that period...this might help you find the reason...
If noting else is running, Cell standby will eat the majority of the battery power.

Yes thats true, exactly the same in my HD2: 3-7mA = 1% an hour or less

Wow, I installed Mdeejay_eVo_Sense_v_2.3Revolution to see if this build helped on battery life. I charged my phone over night and had a full battery at 11AM (according to the meter) but by 7:30PM, my phone was completely dead. During this time, I had two 5 minute phone conversations and used GPS for 9 minutes. Other than that, the screen was not active and I didn't have WiFi enabled. Is this typical? Doesn't make running Android very practical on the HD2. This is only the second build I've tried but it's not looking very promising.

Something is wrong with your build. Try his newer build. They got a new kernel. If that were my habits, my battery would drop by only about 25%. You should install "current widget" from the market. It help you keep track of battery usage. On standby, most people and I got about 3~7mA. If you get a higher mA, that mean something is eating your battery.
Please give Mdj's New Build "Froyo Sense Revolution 1.6" that comes with his new kernel which is suppose to make battery last longer. Hope this helps.

i hope this enlightens you and yes wifi kills battery but it is not the biggest battery killer and wifi is more harmful to your battery life if it is not connected which means it is constantly searching for a network which sucks the life out of your battery.

I think the wifi modules on the new kernels (Hastarin > 8 & MDJ) are consuming too much power.
I usually got 5 ~ 8 mA in sleeping mode with my wifi turning on on the previous kernels, but now I got 8~60 mA and the battery status is showing that wifi is taking about 30% of the battery. Maybe this is because the 802.1n is enabled by default!

battery usage assessment

I decided to test - on my DHD with Current widget - how much electricity does different hardware parts and softwares use.
I test the battery usage with different brightness settings, wifi and mobile internet download, call, call over bluetooth, music, games, etc. I do it with stock battery, and with LeeDroid 1.4.1 (what is 1.72 based and uses stock kernel) Most tests made in flight mode to make as accurate as possible.
Now, the battery is 1230 mAh what is 1230 mA x 60 minutes = 73800 mAmin. It means if the phone uses 123 mA, than it would last 10 hours (123 mA x 10 h = 1230 mAh). And if the screen uses at least 73 mA, than ( 1230 mAh / 73 mA = 16,85 h ) it won't last more than 16,85 hours with screen on. And it means that only the screen is on on the lowest brightness. So don't expect more than 16,85 hours if you continously browse, play, chat, etc.
Screen:
In flight mode.
I took the lowest number, because the screen uses what it needs, and sometimes some process starts.
brightness---->usage
0%...............73 mA
15%.............76 mA
30%.............92 mA
45%.............107 mA
60%.............125 mA
75%.............149 mA
90%.............172 mA
100%...........191 mA
If nothing else uses much electricity, you can expect 10-15 h screen on, on average brightness.
Music:
In flight mode, screen off.
Normal text - speaker; bold text - headphones; normal text - active speakers
volume------>usage--------->usage---------->usage
0.................49 mA.............52 mA.............50,5 mA
5.................50 mA.............54 mA.............51,5 mA
10...............55 mA.............57 mA.............52,5 mA
15(max)........75 mA.............62 mA...............55 mA
It's enough for about 24 h music with volume on around 10 (in flight mode, screen off).
-Real life test:
Today morning I used my phone for listening music only. It playd music for 6,5 hours and it used 30% battery.
It is 4,6% per hour.
There was no flight mode or other special settings. Of course wifi, bluetooth, etc. were turned off.
It means, that it used 56,8 mA, what is quite good, and a full charge lasts for 21,5 hours with this usage.
Download:
Screen continously on lowest brightness, what uses 73 mA
wifi..............220 mA - 70 mA
3G...............300 mA - 70 mA
GPRS............100 mA - 70 mA
It took 30 sec to download over wifi and 3G, and it downloaded 10% in 6-8 min.
So I recommend wifi. Don't forget it at home!
Navigation:
Maps and 3G and GPRS
It used 350 mA with both settings.
I will test the Locations tomorrow and see if there's a big difference.
Games:
Low brightness.
Need for Speed - Shift ....................... 315 mA

Either you can't be arsed reading around to get optimum battery usage out of your DHD (wifi off when not in use, battery calibration etc) or you have a hardware fault! My battery easily lasts 15-18 hours of heavy usebetween charges (currently at 78% after 11 hours unplugged albeit with moderate use)

I'd relay like to know how you have achieved that kind of usage with heavy usage, I can get my DHD to last the day, but its always giving me 15% or worse warnings by 11pm after being unplugged at 9am. I don't use it excessively, bit of browsing, screen on auto, bit of music. The battery life has gotten way better since I got the phone. Does calibration name that much difference, I run the phone basically right the way down every day as it is.
Just be nice to use it as much as id like to (aka not use it and worry about it dying) and still last the day.

After doing the battery reset, I finaly got through the hole day with heavy use, without worying that my battery runs out. If you havent done it yet, do it! Tried diffrent methods, but the one that worked was the one that HTC recomended. Charge with phone on for 8 houres, unplugg charger, shut down, charge for one houre, unplug, turn on, wait two minutes, shut down and charge for one houre. Remember to disable the fastboot befor shutting down phone.

There are numerous posts in these forums where people have doubled their battery life by calibration, I won't claim any such results as I fiddle that much that I can't really pinpoint one factor, so yes it can I believe what is happening is that as the battery improves with charge cycles the dhd is assuming it's capacity remains the same so with calibration you are resetting the max charge level

Can you list down the items under "Android System Process"? I am using my phone roughly the same way you mentioned on your other post but I'm at 8-hours with 80% left. Maybe you have an app doing the damage.

Stand-by consumption

Sorry for my bad english...
However, I installed "battery monitor widget" to see consumption in stand by ... I noticed that with no background applications, consumption is almost always around 100 mA ... to you?

You are able to see current readings in mA with battery monitor? Because so far the current widget does not seem to be working with this phone.
Regular standby current reading should be 5-10mA or so on the nexus one, desire, xperia arc, desire HD, so 100 mA is way too high.
Take some over night readings to confirm. It should be much less than 100 mA.

How would you go about finding this out.
What would be classed as normal standby use - I reckon mine is using 2 - 3% per hour as long as wifi is disabled.

I use juice defender, so with everything syncing but data only enabled every 30mins, i lose 1% an hour on standby...
without i'd say about 2%, as most apps only sync every 15mins or 30min anyways, other than push email, which of course depends on how popular you are lol

i figured out that wifi on has lower mA value than 3g. on all my ex phones it was different.
i now switched off wifi, switched off mobile data via apndroid and the mA dropped down to 5.

on every phone i have owned, wifi was always better than 3G. on wifi the power draw stays at 6mA for me. on 3G it is higher. always been like this on my nexus one, desire, etc. nothing new.
what IS good news is that the SGS2 outputs current readings. i'm surprised any apps are able to find the current reading so soon though. usually they have to be updated for the new phone model.

I'm wondering the same thing... the Desire Z only comes with a 1300mAh battery... My previous phone had a more powerfull battery (2100mAh) and that was an older model WM6 smartphone (which was rubbish on power savings) and it would outlast the desire Z... Even after two years of extensive use, the old phone's battery is better then this phones brand new battery
I've been unable to find any official HTC batteries for the Desire Z which pack more juice...

I am in the process of 'breaking in' a new 1800 MuganPower battery. Fits perfectly with no mods needed.
It should take a few more charges etc to settle down, so things should theoretically improve.
I pulled the plug off charge 6.5 hours ago.
I have it set to use wifi when at home, and 3g for the phone connection (I have a 3G femtocell at home).
When I leave my home area, it switches off 3g and wifi and drops to 2g.
I have made a couple of 2 minute calls, checked my emails and twitter, and was out of the house for say 1.5 hours earlier.
I have had a couple of texts to which i replied.
I am on 95% charge now, and pretty pleased with that.

I've got the same mugen battery, and get through a full day easily no matter what I do. Screen full bright, wifi always on, some internet, games, gps.... etc. Only 7 hours of battery to me sounds terrible.

since my last post, i havent touched the phone at all, and its got 66% charge -__- i seriously need a better battery, may buy the mugen, would you say they are worth it?

the battery seems okay when not touching the phone, as i have only checked facebook for 2 minutes, and sent around 10 texts (been playing football)
looks like imma turn off wifi when not using it from now!

When I first got my Desire Z when it first came out I was pretty disappointed in the battery life. I tried programs like juice defender and minimized every possible battery sucking option I could find. I could maybe get 12 hours of use out of it so I bought a 1800mAh MuganPower battery which gave me maybe 15 hours instead. Pretty poor I thought but what more could I do?
A couple of months ago I finally did a factory reset after encountering a lot of frustrating little bugs, some of which had been around since the phone was new. Since then not only has my phone worked a lot better and faster, but battery life is MUCH improved. My phone now consistently lasts 24 - 30 hours with the same usage or more than I was using it before. So obviously buggy software can make a huge impact on battery life and it's not something you are going to be able to easily discern as to what program(s) are causing the problem.

Hmmm im not sure then..
