Hey guys. I'm a bit new to this, and I have a few questions. 1. Does having a faster microsdcard worsen the battery life of android running on an hd2? 2. With set CPU clocked back to 576 MHz Max 245 min, and all the settings toned back, I barely make it through a days use on my nexus one 2.2 build. Is this normal? Does battery vary greatly from build to build? Is there a build known for good battery life?

Android builds will always use much more power than WinMo, reverse engineering the drivers is not ideal nor efficient. Some builds use less power than others, best try a few with the current widget installed.
This is a thread on SD card power, I'm not sure it makes a huge difference. If you check the power usage app you will the OS is using 2 or 3 times the power that the screen is - this isn't good for battery life.
Hi lads, iam new to this myself I got my hd2 about 2 weeks ago and havnt had out of my hand since.. the only changes I have made was download hspl3 & flash radio 2.14 and I am currently running darkstones froyo 2.2 and I love it.. the only prob I had for my self was battery it was eating it.. when screen was off I was getting around 168ma and using phone was was up to about 600ma.. after about a week of searching I found out a few things and now I get a full day wit heavy usage. I downloaded setcpu,advanced task killer,green power free,changed a few settings on my phone and now I have a battery tats just as good as running WM.. ill get the exact settings up for u later if u want... hope it helps
after doing a task29, i loaded "vbn reloaded" (minimal winmo rom) ;
use EBL android loader and load mdeejay EvoSense 2.0 revolution ;
using "currentwidget" my battery usage is only 7mA idle with four email
accounts getting updated in the background.
Been using android as the (only) daily OS
z
ps just did a rm /data/system/batterystats.bin
need to see if it charges to "100%"
if only battery usage GOES DOWN WHILE ACTUALLY USING ANDROID,
that would be penultimate
(ultimate obviously is NAND boot )

I've been testing 2 different batteries fully charged with phone off. Using current widget they get the same readings about 7ma with screen off and average 200 on. One battery drains at about twice the rate of the other. Im pretty sure one is defective. I've cycled both to make sure. Also running on wm I get the same experience. If your lucky enough to catch a battery problem in the first 3 months of purchase from t-mobile they may send you another like they did for me.

heres a good thread on conditioning the battery
http://forum.xda-developers.com/showthread.php?t=827355
as far as sd card speed, a faster card will use less system rescources due to faster read/write speeds, ie: the cpu is under less load for a shorter period of time.
faster io performance = better battery life.
side note, underclocking to far will hurt battery life. this is due to it takeing longer to complete tasks. so if your like me and do a lot of turn the screen on, check some thing , turn it off, then the longer the screen's on the more your draining it.
I'm using Mdeejay rEVOlution 2.3 ROM. 'Android System' is using 58% of my battery, Chucky lite ROM with most of the WM settings off, and Hastarin Kernel (can't remember which number). Is this right?
No, usually Display takes most of the battery. Might be a bad build or something, you might want to format your SD card and load a new version of android on it.

Cheers for the reply! I guess I'll crack on with it. Good job it's a Sunday, hey?
i have installed android for the first time yesterday. this is all new to me (flashing roms and stuff) but it all went ok. i have though noticed that battery life is poor. Firstly, i have searched the forum and noted that many users are stating what the battery usage is in mA. how exactly is this measured? is there an app? secondly, it appears the battery can be effected by what rom, radio etc is installed. if i was to try a different rom or radio, would i have to install android again along with all my apps?
thanks
i kind of have this problem too but it hink thats just how these early builds are.
Use currentwidget to measure mA.
My mA idle get down t 5mA, but I am still having some issues getting battery life that i think is acceptable

thanks for that. just tried the widget. lowest i get is 7mA
5 to 9 mA is great battery consumption at idle, I'm having an issue staying there, I bottom out one day at 3mA but then today my phone doesn't drop below 50mA at idle. Windows Rom and radios are important for it to run smoothly but I don't think a lite rom makes a difference over a full rom, when haret launches , is gonna keep anything from running on windows(so I hear) I've tried many many roms, and the vbn rom, which is a super lite rom, didn't perform better than what I'm using right now which is energy cht. Radio will keep you from having issues with the phone waking up,(bsod) I've tried a bunch of radios and settled with the 2.15, a lot of people swear by it!
Im looking for a rom with amazing battery life.....
Help Please!!!!!
Thanks!!!!
The rom i've found to be best on battery life is Royal Ginger. I've gone 2 days and a few hours on it with moderate use.

I also get amazing battery life on RoyalGinger 1.5

I was at 36 hours with wifi on for at least 24 of that. And I plugged it in with 10% remaining.
Edit: Make sure to calibrate your battery though. Don't judge the ROM off of the first 1 or 2 days.
Thanks ill try it.....
And how do i do the thing you was saying about the battery....

Search is your friend... there are a few guides in the Dev section
Sent from my HTC Glacier using XDA App
I have great battery life on CM7. There are a number of things that affect your battery life that all need to be taken into consideration.
ROM
- Find something by a reputable team like CyanogenMod and Team Royal. Their ROMs don't have HTC's SenseUI overlay and aren't bogegd down by the extra framework and overhead needed for Sense.
Kernel and CPU Clocking
- If the ROM supports changing the CPU clock speed, you can have your device run at lower clock speeds when idle (such as when the screen turns off), theoretically saving battery during those times. There are some great kernels by faux123 in the Development section.
- You can also try an undervolted kernel. Performance is no different than a stock voltage version of the same kernel, it just uses less battery to do the same functions.
The Screen
- This eats up battery like a beast. I don't use automatic brightness as most of the time a low setting is good enough (i.e. indoors).
- Gaming and other graphic-intensive activities will chew up battery
- I also use relatively dark-colored backgrounds because I think (can't prove) that it's requires less effort for the screen to show darker colors. Somewhere I read that it's easier to read light text on dark than dark text on light, so there's that too.
Connections
- GPS takes lots of power to use, so keep it off until you need it.
- Wi-Fi and bluetooth will continuously scan for connections while they are on, so leave those off while you aren't using them.
- In areas with poor network signal strength, your phone uses more energy than in areas with great signal strength.
Apps
- Be selective about which apps you install and run, especially ones designed to run all the time. I like to have something that can monitor CPU usage so that I can see when something is hogging system resources. Kind of like the Task Manager in Windows.
TasKillers - DON'T USE THEM!!!
- TasKillers cause more problems than they solve. Android is better at closing idle/unnecessary tasks than any TasKiller app.
- Killing tasks with TasKillers also adversely affects the stability of your device.
- Many of the things killed by TasKillers end up restarting anyway because they're needed for something, so you're repeatedly killing and starting the same apps over and over again. Guess how much battery that saves (hint: less than zero).
- If anything, use AutoKiller Memory Optimizer. This doesn't kill apps, it changes settings in Android that determine when to start closing apps to free memory.
Thanks you very much!!1
The biggest deal that has to do with battery life is how hard you push the phone. It has nothing to do with ROM or kernels...
If you truely wanted to test a ROM to see how the the battery life stack against each other you'd have to have x amount of devices with the SAME EXACT settings within the given ROM. Each phone running a different ROM. I ran a Sense ROM over the weekend and got HORRIBLE battery life. but other claim Cyanogen is the pits.
can someone help me with the battery life on my htc desire hd i want better battery life without dissabling features, thaanks in advance
Well, there are many factors to getting good battery life.
Matching Radio/RIL can be a good start, especially if rooted.
Definitely ROM's also have a big part.
Overall usage will also bare a pretty big footprint.
I get about 18 hours on a typical work day, with moderate usage which is generally enough for going to work, coming home, and then still have plenty of battery left when I'm ready to go to bed, which is obviously when I charge my phone.

Define "disable" and "features".
disable automatic synchronization and shine
+1 there's nothing wrong with setting your Facebook, Twitter, Email, background syncing, weather etc to less frequent but it will obviously give you more battery life than syncing every 5 minutes, common sense really. An app to preserve battery I have found is Apndroid. Have the widget on your home and you can use 3G when you need it rather than not.

I disable automatic sync of all apps. I only update manually when I use them.
if you can echo all the timings I've been disabled, the sync I maualmente when I access the email application, facebook, etc. .. tweteer
have you rooted your phone? which rom are you using? some details will be appreciated...
tried custom roms? i usually get better battery life with them,
also setting off auto brightness helps a lot for me.
Green power free,its amazing my battery lasts at least 60% longer with this app,amazing get it

hey, mate... you've got some very generic question... specific info like ROM you're using, Radio, Kernel would bring justice for members to give you some more specific help.
This probably might help:
ROM CoreDroid 7
Radio 12.54.60.25_26.09.04.11_M2 - (HTC Ace Gingerbread S Generic 2.36.0)
RIL_12.54.60.25_26.09.04.11_M2
Kernel LeeDrOiD GB V3.1.6 - 2.6.35.13 BFS KERNEL (thanks to LeeDroid)
Live wallpaper Nexus Revamp
disabled wifi, refresh, gps (used powercontrol widget for accesibility).
After flashing, my battery was drained in 5 hours even after an overnight full charge.

Cyanideskittle2010 tips will prove really helpful. tweak around phone settings which are my priorities... things i don't normally use disabled them, enabled them when i need to.
also, installed cpu clocking, initially used setcpu, then moved up to cputuner which gave me more options... juicedefender also can help if you prefer it. setcpu or cputuner are both available in market.
gave my phone 24 - 48 hours, after battery calibration, full batterystats wipe, now i am good at 30 hours battery time.
used to have 36 hours battlife but was using CoreDroid 6.7 then... shifted to CoreDroid 7 because i just love its UI.
hope this helps! credits to all xda cooks & chefs, sergio76, coredroid team etc..
the new honeysense 6.0 rom has a extremly good battery life. i wiped the battery stats and now my battery lasts abaout 2 days instead of one

Yeah I have been using APNdroid since Android 1.6 and always have it on my Android phones, battery does last miles longer by using the on off widget to disable 3G when you don't need to be using it.

Don't want to steal your post but i just have a question haha.
I ordered a battery off eBay the new battery runs on 1600mAh while the original battery goes on 1230 mAh. Should i worry about battery stats i should wipe after replacing the battery or something like that ?

I think it's better to wipe when the phone is fully charged (test with currentwidget) but i think to best is to use the original battery. It can damage your phone and I often read that those batterys don't have more power than the original.
Is it normal that from full battery after night I have only 50%? Extremely strange for me... I have ARHD 5.1.10, ANDIDA 1800 mAh
i am using ARHD, it has good battery life. Works for me
I'm running into a strange issue where my tablet will be running fine then all the sudden battery life will start to suck and when looking at my batter usage it shows "Android OS" will show something like 70% of usage where normally display and wifi are well above that on the list.
I don't know what Android OS is so I'm looking for an app to give me a good granular view of what is running and how much of the CPU it is using. A battery usage app that gives a more complete list of battery usage by app would also be helpful. Spare parts has this functionality but it force closes when I try to use it.
Anyone else having this drain or have a good app for tracking app/battery usage?
I've used BetterBatteryStats from the Market ( https://market.android.com/details?id=com.asksven.betterbatterystats ) Though not free it helped me find the app that was eating my battery. My phone would drop to 30-40% in a day with little or no use. Now with the same use it at 70-80% so I can go 2 days easy unless I use the phone alot.
According to the reviews for this app is is apparently available free for XDA members. Any idea where to find this (or another app that the review might be referring to)?

"Don't bother yourself. An upgraded free app is at xda site. Developer answers vaguely. Also it has bugs."
I use SystemPanel. With the long battery life of these tablets (and the fact that the screen chews through the battery faster than anything else for me) I keep it monitoring at all times and every now and then check up on what's taking the battery.
I can't remember if I purchased this or not, I don't believe I did but could be wrong. I am pretty sure there's a free version of it.
Battery monitor widget all the way
