I'd like to hear some experiences that everyone is having on how the battery life is on the stock ROM (POST OTA, NOT OVERCLOCKED) vs custom ROMs (Again, NOT overclocked).
I've tried the Virtuous ROM, and as expected the battery life got slurped down like coca-cola! CM6.1 isn't as bad, but still seems to suck the life out of the battery quite a bit faster than stock.
Is everyone seeing similar? What makes the stock ROM so much better on the battery?
My experience was actually quite the opposite. When I switched to CM, my battery life improved by about 20-25%. I have a NAM Desire Z so it was running HTC Sense over Froyo.
Remember that it takes a few days of usage for your battery to 'calibrate' itself to the new ROM. My first two days on CM were really bad, but since then, battery life has improved greatly. Yesterday, after moderate use and 15 hours, I still had 45% of my battery left. With my stock ROM, I would be lucky to get 15 hours of use out of the phone period.
As far as overclocking goes, I haven't seen much of a difference in battery life. Reason is, even though you are overclocked when the screen is on, you can adjust settings to under-clock at other times, saving battery power.
I would recommend trying a Custom ROM for 4-5 days, that will give you a better idea about its battery life. Also, there are lots of settings you can tweak that affect battery life greatly. Widgets, background data, signal strength... SOO many variables in personal usage that battery life is going to fluctuate user to user regardless.
Hey guys, I am on cm 7 nightly #11. I am on radio 09.01 and have experimented with Chad's and the stock kernel.
I have background data, auto-sync, wifi, bluetooth, gps all off. I dont have facebook or anything pushing either. Screen brightness is on about 60%.
With the seido 1750 mah battery, I am getting around 7-8 hours of battery. That is to the bone dead .
That is making maybe 1 call a day, a couple dozen texts, browsing the web a bit and listening to an hour or so of music/pandora.
In spare parts it says under 'other usage'. Running 42.7%, screen on 23.8%. 'Partial wake' only ones on here are really music and pandora, but they are relatively small slivers.
Under settings it is 68% display, 8% cell standby, 7% voicecalls, 4% android, 4% idle.
I have tried wiping battery stats, doing the drain all the way technique, etc.
Anyone have any suggestion on what to do here?
Thanks.
I'h suggest moving to Cymod 7 RC1 (unless you mean the new nightly, then I'm not sure) I have been running cyanogenmod since before the nightlies hit and I've never had battery that bad. I get about 3 days of standby out of my phone on RC1 and the incredikernel. I listen to pandora on 3G (charging only in that time) about an hour a day and never charge otherwise unless I'm using it heavily. I text semi often, but don't really listen to music or call.
Seems wildly different that my experience. I take it this is specific to this rom, and your battery is better on others, ie battery itself not going south? With pretty similar usage and syncs to yours, I make it about 10 hours to use 50% of batt while at work. That's with stock battery. Only new nightly #8 with stock cm7 kernel.
1) change to 2.15 radio
2) did you buy the battery off ebay for $10? If so its really a 1250mAh or so. Either way OEM batteries are better than the aftermarket (ie Siedio)
3) Is the battery really old? If so it may be wearing down
4) Kernels are all decent, they should all get better than what you are getting...
5) Don't overclock to 1300+ it should run smooth at 998 or whatever it is.
I get 12+ hours of moderate use out of my OEM 1500mAh battery.
When I first started on the nightlies and flashing different kernels, I was having the same issue.
I stopped flashing other kernels and started using the stock cm7 kernel, now I am getting awesome battery life. Also, after flashing, several people recommend immediate rebooting to improve battery life.
Thanks guys.
Few questions.
1.) Radio 2.15? I am on 2.15.00.09.01 currently. Is that the same?
2.) Mine is an authentic Seido. But should I start using the OEM 1300mah battery?
Oh, I should mention. I don't overclock at all.
I was using the stock battery and got ~6 hours even with UC to ~850 most of the time and ~200 while screen off. Turns out my battery was defective and even now OCing to ~1100 most of the time I'm getting 4x the battery. Of course I couldn't be sure that my battery was defective until after I bought the new one but if the battery life just doesn't make sense then you might want to try going back to stock (assuming that's fine) and comparing.
try a different battery maybe
i currently have the stock battery which was only used a couple days
a HTC 1500 battery
a seido 1750 battery but i havent tried any of the other batteries in awhile but i also use CM7 nightlies on #11 because it seems to have best battery life
maybe ill try my other battiers and see my findings
I've had a similar experience and I'm fairly certain it was not my battery. The battery worked great with other ROM's; Normal usage of my phone would yield roughly 40% remaining battery life at the end of the day.
After going to CM7 (I started at #38) my battery has been lousy. I can't get through a day at all.
Two days ago I flashed incredikernel 2272011 as well as CM7 build #11. I'm using the default smartass governor and my battery performance is back where it used to be. Going through an entire day for me is no problem with normal usage.
Not sure if that helps but I've had good luck with this kernel thus far. Oh... and phone has been rock solid!
I'm on CM7 Nightly 11 right now with stock kernel. Seidio 1750 that I've had since last June. I've recently been comparing Tiamat's 3.14 to stock. If I'm on any kernel that has Smartass I'll use that as my governor. If I'm on the stock kernel then I use SetCPU with the kernel set to ondemand and a screen off profile set to 245. Either scenario seems to give me pretty good battery life, but I think Tiamat's with smartass may be a little better. With any kernel I've had it overclocked to 1.03.
Also, the brightness settings based off of HTC's ROM that were posted in the cm nightly thread in the development section have worked great. I've definitely noticed an increase in battery life.
I use advanced task manager with the shortcut on the desktop. I leave essentials running in the background but try to make sure everything else is killed.
All in all with the current setup I have I can get roughly 12-14 hours with heavy texting, 4-5 phone calls, internet and games scattered throughout the day.
I found this thread on Desize HD forum:
http://forum.xda-developers.com/showthread.php?t=984337&page=6
then i wonder can we get some information to know where the problem come from?=> we can fix the battery drain issue on all GB build. Hope it help out devs. cheer
Sorry for my bad english
What drain?
Are there really so many problems with drainage on CM7/GB builds?
2d, 3h, 25m on battery with 60% left.
The first CM7 build i used is the one in my sig. I'm amazed by the lack of problems with this build
The only drain that's still ongoing is bluetooth on standby drain AFAIK. This DSP issue is not related to the HD2, thus I don't think it's valid to implement. With bluetooth turned off and heavy usage, I get roughly 2 days out of my device also... I really don't think the drain is a big issue. Honestly, the biggest issues is (And it's not much): Robot voice once in a while, some Wifi issues (EAP mostly), Wakeup lag and BT drain on standby.
the drain is related to the toolchain used to compile our kernals and roms?). I however can do easily 3 days with out charging on android, using the same setup as KrewsialNL
Actually
Actually, i get pretty horrible battery life across all builds...
it could be that I have a v1 TMOUS hd2 though... something is weird with it. I always get random energy spikes (even with sync off)
can't get more than 14-18 hours...
My battery drainage is fine using the Typhoon rom. I think some people are expecting a little too much out of their batteries.
It's only 1230mah if it was 1500mah it would have been way better.

How on EARTH are you getting that long out of your battery?
Are you using the phone at all?
I've used loads of different builds and never come even close to half that battery life, in fact no more than about 20hours MAX with light usage.
I am using Juice Defender to disable my WiFi and Data when the phone is not in use too.
Any tips?
I have run all the latest GB builds and I also get this weird spike (around 70mA to 100mA) usually when I leave the phone overnight (not charging) and this drains my battery down to almost empty by morning. This is with bluetooth off and wifi on. No apps installed on the phone.

mmmm That CM7 build has great battery life but yours is beyond reality... are you sure you haven't connect the phone in those 2 days?
Mine says "4D 10h 1m 50s on battery" and has more than 50% left but it has 3 green spikes (in battery use, I connected 3 times but didnt charge to 100%)

Well I was going to say exactly EXACTLY the same thing! Except that i didn't like Juice Defender
Is battery THAT GOOD?!?
Battery
well yes, it's certainly feasible...
it's just that MY hd2 specifically gets random spikes in energy usage.... I'm not sure why, been trying to resolve it for a while.
I don't really get those spikes in WM, only when I go someplace that doesn't have signal... it will spike up initially and then settle down (dutty's rom)
However, with these android roms.... i get random spikes of increased current around 100-200ma while the phone is in sleep. Bluetooth off, sync off, wifi off etc.
also, when the phone is in use... it is not uncommon to have current of 400+ consumption... hitting 500+ when web browsing...
I never got this high in windows mobile...generally around 400 when streaming youtube in wm. I'm wondering if it is an android thing...
edit:
in a perfect world, our battery consumption should stay around 4ma constantly... Which we know that isn't always the case because we have data syncing and signal strength changing...but to give you an idea....
if we have a 1230mah battery... dividing that by the current draw (4ma) gives us a standby time of ~307.5h....
that's ~12.8 days
however, with my current usage... say, i'm getting about 14 hours out of my battery... that's like if i constantly had a current draw of ~68ma...
Taking a look of my usage charts.... if we say the phone is only in use for 6 hours, and the rest is in standby for 10h at 4ma...
the 6 hours would have a power consumption of ~300ma the whole time....
which i think is kinda excessive....
meh. i don't know.
perhaps i'll upload my usage charts later... lately on this new rom, i've been getting only 8 hours of battery :/
but it could be because i've been playing around with it too much
I am on a TMO US HD2 first generation and I am doing good if I can get 6 hrs of battery with the stock battery and normal usage. No wifi, 3/4g, no GPS, and auto screen dim. If I am using the net or something like angry birds I am down to 2-3 hrs max. I have tried underclocking and still not getting a full 8 hrs of life. Would love to find a solid rom that lasts 12 hrs or more. Ordered an extended battery so maybe that will help a bit.

I have the same TMO US 1st Gen. I'm using
TyphooN CyanogenMod 7
http://forum.xda-developers.com/showthread.php?t=933951 just uncheck bluethoot when you don't use it.
I get from 1 to 2 days with moderate use.
Define what's good and what bad with the standard battery? I have been getting on average about 10-15 hours and that's with doing alot of texting, web surfing, mp3 player and xda lol, and crunchyroll (streaming shows) usually over 3g but sometimes over 4g.

Thanks for the tip. I have a second HD2 that I test builds on and I was actually in the process of installing the ROM you mentioned last night I am excited that this may be the rom to drop on my daily driver I have noticed that non GB roms (2.2) seem to have much stronger WIFI signal strength so I am hopeful this GB version will have solid WIFI signal too. Love using GB but hate the wifi issues I keep having. Thanks agian for the tip.
Well, this thread didn't go anywhere.
I'm finally trying to get up the courage to switch to a NAND rom.
I get awful battery life out of my SD build I've been playing with and that is with a 1500mAh replacement battery.
I'd hate to switch only to find myself in the same position?

battery drain on SD builds may vary from SD card used.
I can confirm that from my experience, i was not able to use the phone on the second day (total up time 1d + 12h TOP) when i was on SD builds
BUT.. while on NAND (no A2SD no Data2SD)
I can confirm that i can now use the phone for 2d + some hours, depending on use.
All battery info apps told me that battery life is Good (not excellent, not very good).
Made the switch. Battery life as good if not better than with WM and SD build. I feel the biggest improvement came when I installed setCPU.

Hey there,
I want to know what is the BEST setup to maximize battery life. What ROM? What Kernel? What UnderVolt ( if any )? What Radio?
My room mate has an iPhone that he modded and it now lasts two days without being charged and that's with moderate usage. I'd like to out do him with my Android. Any help?
-Reiz
So far personally I've had the best experience with the following :
ROM : CM7 ( 7.0.0 )
Kernel : Tiamat 2.6.32.27
Radio : 11.19
I can't seem to get undervolting to work since I don't have the folder that Viper describes even though I am using an AOSP rom ( as far as I know ) . o.o It's odd really... Anyways, that usually gets me about 20 hours of usage or so .
Twenty hours isn't bad, as the Incredible isn't known for it's battery life. You won't get what your roommate's getting with his phone, maybe get a bigger battery...? I don't think you're going to really out do yourself with the experience you've posted, I'd be happy with that.
I am running SkyRaider 4.0, Chad's 12232010 kernel, OC'd to 1.0368 (small OC, I know) with the leaked 04.08 radio, and I can get about 20 - 24 hours before charging, low to moderate usage (no games, emails for work/personal, maybe 1 call of 5 minutes, lots of web browsing).
Cm7 stock kernal. On metro pcs with a seidio 3500 mah extended battery. Unplug at 7am 12 hours later only sitting on 74% lmao. And in that time bout 100 text. And 200 work emails.. and 30 mins of surfing on lunch. This setup has been the best for me on bat life.. used to run sense and my bat life would just suck..

Two things that will kill your battery faster than anything:
-Anything that syncs
-your screen
So, turn your brightness and screen timeout down and turn off anything you don't need syncing all the time, or at least turn the sync frequency down.
Also, keep your wifi, vibration, tactile feedback, and gps off unless you really need it.
Kernels, roms, undervolting...no where near as effective.
Think about your phone as a smaller version of a laptop (which it pretty much is), what's going to save you the most energy: throttling your cpu speed, or turning the screen brightness down?
Much love brother
Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.
