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 would love to know what your settings are, after 3 hours lite use i lost 45% battery, my gps is off and background update is also off....
2.12.50.xxxx radio.img
it has a lot to do with radi youre using, i found this one really good, have good bttery life, 3g, hdspa, wifi, gps, mms and all working really good...
Hello to all, iam using the android shubcraft version on my hd2 and i cant charge my device 100%. It stops on 85%. Did you guys have an idea??

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.
Hello,
I'v tried 3 ROM's (gingeryoshi 1.2, froyo by lazlo(last one)) and different kernels but on 2.2.x or 2.3.x my G1 get battery drain really fast..
Now I'm using COS-DS 2.3.4 and the battery drain is lower (when the mobile is on "stand by" drains really lower.. But when I get a call (2.. or 3 minutes..) or use Camera, Internet.. etc it consume battery really fast. (From the 3 ROM's above the one that giveme best baterry life on 2.x.x was COS-DS).
When I use my mobile on 1.x (1.5... 1.6) android ROM the baterry last's better than in those 2.x.x ROMs.
So here is my question.. I need sugestions of ROMs and Kernels for battery saving (I use the mobile a lot).
Thx a lot
I
Anyone can helpe me?
you're going to have to find a rom that you like and then flash a undervolted kernel over it. im using cm7 magpie with an undervolted kernel and battery is good but not great. most roms don't have amazing battery life since they are for speed. the g1 never had great battery life anyway. if you want good battery get an extende battery off ebay.
Thx a lot, do u sugest any kernel to froyo by lazlo with undervloting settings?
The kernel that I'm using with FBL 5.2 is the [email protected] #145. I've tried many with that ROM but this one seem to be working great and I've gotten the best battery life from it. With the radio off, I get over 6-7 hours before it drains a percent or two. With the radio on and I'm stationary with a decent signal, I get only 1 percent drain per 1 1/2 hour when the radio is in standby.
I flashed the kernel after I setup the phone and most of the apps I use. I also flashed this kernel on my wife's G1 with SuperBler v4 and it made a huge difference also. Give it a try. Good luck.
Will a Froyo rom be more conservative regarding battery life than a gingerbread one in the G1?
depends on the rom
Rom: unity 1.29
Kernal:unity V4
Radio: stock gingerbread
Set CPU: wake 1.1GHzmax - 245MHz min.. sleep 368max - 245min
So I recently came to the conclusion that it doesn't matter what Rom I use (sense or asop) that I always have horrible battery life.. I maybe get 4-6 hours of battery life with moderate to heavy use.. I was just wonder what is the best way to set up my phone to get the most out of my battery.. I've used the battery calibration app for all 3 of my batteries and nothing still get the same out of it.. yes I have 3 batteries but if they all die extremely fast whats the point? I've also used juice defender but that only helps if I don't use the phone..I've seen posts of people supposedly using the **** out of there phone and going a full 24 hours.. I just want to know what your settings are if it helps me at all.. oh I also know that T-Mobile recently had or still has 4g network problems but my battery drain has been going on forever ever since I got the phone when it came out.. thanks in advance for the help guys and girls

What i have been doing to counter the 4g problem is use 2g for non phone use times and 4g when i actually need to download or use mobile data. Ive also heard that auto brightness helps drain the battery faster than without. autosync settings can be important too. dont have it sync everything if you dont need it to. I get a long time on my battery and usually set it on the charger at night with 30-40% left.
edit: you didnt list the governer you are using. I use smartass or conservative for screen on or off and they help keep the clock speeds down if you arent doing something heavily dependant on phone speed like a game. Also when you say your radio is stock gingerbread, do you mean the newest leak one or stock that came with the phone? I have found the panache to give me the best reception which in turn saves the phone from draining itself from trying to find a signal.
Whoops New I forgot something..yeah my governors are smartass for when screen on and conservative when sleep.. when I say stock gingerbread radio I meant the link before the panache radio
I got my best battery life using faux123's AOSP roms, and his latest kernel has an undervolted version which makes it waste less battery without taking any toll on the performance. I don't particularly like the sense roms too much because I feel like they drain my battery power faster than aosp ones, and I don't even use all the features to their fullest extent.

I've heard the same thing as well actually. Personally I keep my brightness at minimum all the time(10%), but you could try 25% if that's too dim for you. 40%-60% is usually bright enough to see clearly on even the brightest days too, and I'm one of the unlucky people with a bad screen.
I'd also recommend downloading Muzikant's "AutomateIt" app and setting up some rules. I recommend setting rules that will brighten your display for apps that really need the light(Netflix, Camera, Gallery), and then dimming it back down once you close the applications. You can have it turn off your data and syncing and other such things under specific conditions and times as well, which can help your battery life immensely, and without you actively having to do anything.
And I guess you could try flashing a new radio as well. You might have to test out each one for a few days to notice the differences between them but eventually you'll find which one works best for your area and phone.
If the batteries you're using isn't the stock one, most likely those batteries will die out really quick. They don't hold their charge that well.

Hi! I wanted to know if you guys have a problem with the battery life on SwiftDroid RC5. I have a poor battery life and therefore big battery problems.
i had mine and bought a new batt no probs after that
Yes, I do. Since RC4 and RC5 I have very poor battery life. Before it was enough to charge once every other day, now I have to do it daily.
Actually after installing RC5 it was a disaster as battery didn't keep even 24 hours but after recalibration it's better. But even then during the course of the day while doing basically nothing (say, sending and receiving 3 or 4 sms) it goes down from 99% to 40%.
Edit: I should mention that I overclocked to 800MHz, but I used to do it before RC4.

Same here. I'm moving on Cyanogenmod 6.
yeah swiftdroid is a real battery drainer but
on swiftdroid on average my battery lasted 2 days..
but still i use cyan6!!
good in battery and performance!!
Same here. Experiencing battery problems on SwiftDroid aswell. Like mentioned above the battery drains even when doing nothing. Experience this on basically any mod built on SwifDroid ofcourse. Changed to EleganceSwift, waiting for mike to release AOSP with Bluetooth-free radio ;-)
There's something more to it.
Recently I was playing a bit with my phone, installed couple of applications and then suddenly I realized that battery doesn't drain as fast as it used to. One thing I noted is that for example Videos application doesn't reside in memory anymore. I'm not saying this one was the sole battery hog but I'm starting to suspect that those cases of battery going down very fast may be related to some misbehaving app or apps and not necessarily be Gingerbread's fault.
If that's the case, the solution would be, I imagine, to trim system preferences to have such apps killed fast not to let them stay active.
using ASIS atm, but when I was using RC5 I didn't notice much faster draining. Still, it depends how many apps are running on your device and did you overclock it? I used to have min 250MHz, max 600MHz and it was pretty fine with texting, multiple apps running and music. Now with min 825MHz/max 825MHz it's draining faster ofc
Well,I remember a day when i update to SwiftDroid RC5, the batter drains and there isnt any app running in background after that i changed to a another rom.
btw fdespotovski, Multiverse is my favorite rom, in fact, i wrote on the offcial blog but i have problems with the RC3, statusbar sound widget doesnt work properly for now im on RC2

I'm not using ASIS, still at RC5, and what I reported is that both RC5 and RC4 drain battery much faster than earlier versions. Assuming ASIS is just cosmetic change to RC5 it doesn't surprise me you didn't notice any difference. And again, I do overclock to 800MHz and I do it since M5 if memory serves me well. I know principles of overclocking and I know, and accept, drawbacks that come with it. But when at the same clock RC3 can live two days or more while sometimes RC5 barely manages only one then I suspect something is not right.
I tried to check which applications are responsible for battery drain but system report is not helping when telling that 98% took Android system, 2% cell standby and 2% phone idle.
Sorry for necroposting but I didn't want to litter forum with new thread and the problem itself hasn't go away.
I'm still using SwiftDroid v2.0 RC5 and until recently I still had problem of battery barely keeping one day: whole night on the charger and after moderate to no use during the day on the evening it was almost drained.
Recently I installed one more application (rather unrelated, I'd need really solid proof that CPU Spy directly improves energy usage) and after that the battery easily keeps for two days. Which brings back the theory I have that the short battery life is not necessarily caused by Android itself but by some applications staying in memory and not sleeping properly. If so, installing extra app may help just for this reason that it having higher priority will swap out those misbehaving ones.
Thus I propose little hunt, if anyone's interested. I'd like to stay focused on v2.0 RC5 (maybe RC4/ASIS if you believe the difference is not too big). I need reported both GOOD and BAD battery life. In either case please write down all apps currently in memory (you can skip those you have installed, I'm mostly interested in what comes from ROM). And don't forget to mention which actual version do you use and whether it's good or bad case.
Given some meaningful data I hope to isolate which apps cause excessive battery drainage. I'm not sure what to do with that information next but I think it would be good start anyway.
To make said start, here's what I have:
SwiftDroid 2.0 RC5 / GOOD battery
- DSP Manager
- Usage Timelines Free
- Doit.im
- K-9 Mail
- Auto Memory Manager
- Superuser
- Settings
- TM World Clock
- Go launcher EX (doesn't report itself as staying in memory but I suppose it has to be running somewhere)
custom roms...with gingerbread will definately have faster battery usage!! u cant help it
---------- Post added at 10:33 PM ---------- Previous post was at 10:31 PM ----------
use stock roms.... if u want good battery life!
Guys help please, I have a battery/charging problem after installing RC5, this is my first ever custom ROM, it worked great yesterday, but after charging it over night I'm stuck at 99% it won't go up nor down, the phone won't charge and it won't even connect to PC via USB I tried turning it off completely and then plugged in the charger but it just booted up (is it supposed to do that this is my first android?) and that was it. Everything else works fine, wifi etc.... Is there a way to fix this ? I can't transfer a new custom rom to the sd when it won't connect to the PC

the battery stuck at 99 % is a often coming bug and i don't know any solutions mine goes to 97 % ...
ehen phone is shut down and you plug the charger its normal that its booting(because of fastboot)
connection to pc should work, try another port re-install the drivers
thanks ...............
I also have a battery problem... i have installed this ROM 3 days ago, and now i can't charge my battery over 45-55%. Phone was charging all night long, and batter lasted for a day and a half, but its annoying... btw, what now, do I delete battstats now at 55%, when i can not charge phone to 100%?
Hi everyone,
I have a big problem of battey usage on Android...
I flashed the NexusHD2 rom in a first time and i realised the battery life was very bad ! (I lost 3% for 5 minute of use !)
I flashed the famous Typhoon CM7 rom and it's the same...
My Radio is 2.15.50.14 and i use CLK.
Thanks for your help
Try a different kernel. That helped in ICS, so after some trial-error you should find a good one.
Sent from my HTC HD2 using XDA
What kernel is the best for it ?
I use Hyperdroid w/ seader r9 kernel. I get pretty decent battery life with it. But you also have to remember that the HD2 is a bit older so it has a smaller battery and less power-efficient parts.

Agreed, i flashed STOCK Windows Mobile 6.5 from T-Mobile and the battery lasted exactly the same time as with Android on it. I found that the ROM/Kernel combinations only matter a little. The phone alone has horrible battery capacity.

A bit?! Lol that would obviously help a lot. I'm not quite sure how accurate CurrentWidget is, but in terms of standby battery drain I get 5ma drain with wifi on on my phone. On the same settings on my Mum's Desire S she gets 26ma. However she gets great battery life, which I would only guess is due to the larger battery (and the fact that she barely knows how to use the phone, so the screen isn't on very much at all).

I use batterymonitorwidget pro. And i get around 5ma with wifi and cellular on.
Try using an app called JuiceDefender - it works really well at extending battery life. It basically lets you tweak loads of options to do with data and syncing, so you can have it set that data doesnt run when certain apps are open, or data is off when the screen is off, etc.
There's an ultimate version available, but it is £4.99 from the play store. But I guess that'd be cheaper than a new battery?
The same problem occured to me a few weeks ago. I have been using HyperDroid-CM7 which worked quite decent for 5 or 6 months and had very good battery life. ABut a few weeks ago suddenly the battery life became to awfuly decay, wasting 20% of the energy for idle hour instead of the normal 1-2. I changed the rom to the NexusHD2 ICS port and the battery life slightly improved but rhe problem stays the same. Could it be because the battery itself is broken or some software calibrations are needed (I haben't done any for an year since I bought the device)
