[Q] Battery Life, Standby Current

Hey all,
I just picked up a G2 and got all excited and dumped Virtuous onto it (I'm very used to Sense).
I soon realized that the battery life of this thing is ridiculously bad. I put CurrentWidget on it (I switched from Android on HD2), and noted that it's draining, on standby, at ~60-80 mA. That's very high; on the Android on HD2, it sometimes is as low as 7-9mA (on average).
I'm not doing anything particularly special, and I've got the same settings on both. It's unlikely it's the reading, as the percentages go down like crazy on the G2 (or get stuck; it often gets stuck at 96% for an hour or two and then goes down very quickly). Quantitatively, it's about 1% per five or ten minutes, while I could get maybe 1% per half hour or 45 minutes on the HD2.
Has anybody done any CurrentWidget tests on their G2? I've searched around, and it seems that not many others are using this test (it's very popular over with the HD2 kids. ). Does anybody have numbers they'd like to share? I'd be very interested in seeing them!
I'll, meanwhile, try the AOSP and stock build again to see how the widget performs on that. I'm very sure this isn't normal, though...
Thanks!

The norm for me is 28-38ma on stand by, you will not be able to get it as low as the HD2. It stays at 100% for about 1 1/2 hours after that it drops and at the 60's slows down again.

Do you have any task killers running? Menu, setting, about phone, battery stats, then youll see what app is eating the battery.

I've posted before and was able to get the phone to last 12 hours on 1%. It drained at such a low mA that it said 0 and 1 often. I will try to get it that low if i can again since i changed to RC4.
Will post screenshots and logs of information on apps running then make a guide about what settings need to be where and what files need to be deleted and added.

That's odd, though. I would've expected otherwise, considering that Android on HD2 requires most things to read/write to SD card, which would supposedly be more power-hungry than writing to NAND...
Nope; I've run tests on almost pure stock builds (just Astro + CurrentWidget + SetCPU installed, but I don't even have SetCPU running...). Happens on both Virtuous and Villain (Sense builds). Thanks for your input!

That's amazing. Please do post additional information when you have time! I'd be happy to spend some time in the coming weeks to replicate your behavior.

for some reason my g2s battery got better as time progressed.
fresh out the box=needed 2 charges a day
3 weeks later= 7am-10pm still at 36% with HEAVY use.

Shouldn't Standby eat more than the HD2 based on it being 4g? Also I use the GSM/CDMA Auto which has increased my battery life significantly. *#*#4636#*#* phone info. My time without signal was around 9% and is down to 0 since changing it. I am a pretty heavy user and I usually go about 24-30 hours on a single charge. (I'm using the chitech 1800 mah battery though.)
Edit: I'm OC'd to 1497 with 245/245 screen off profile.

I really want to get that type of battery life! It might have something to do with batterystats.bin being well conditioned. I've tried running to zero and it seems to help a little little bit...

That might be true, although I don't have any 4g around in my area. That said, I think HSPA+ is just another bit onto HSDPA, which is what the HD2 has anyway. I don't think it should consume that much more power... (3x fold!). I've tried switching to GSM/CDMA Auto (PRL), but I was using GSM Auto already. We'll see if it helps too!
Thanks guys for your input and feedback; I hope it'll help others, too.

Argh, it's not "4G", that's just some made-up T-Mobile nonsense about HSPA+ (still an uprated 3G technology).

[Q] Help? :(

Well, ill start off by saying "Im james! "
I recently made the switch to android because i absolutely love the capabilities and the functionality. I got myself an Incredible. Rooted and and installed Redemptive revolution and got sucky battery life. Then yesterday it starts raining and gets really cloudy. I lose my 3g coverage about an hour into the storm. Im guessing this is normal? Well i decide to install Myn's two point two, with kinxklick's LV kernel in an attempt to get better battery life.
My current standing: Im running Myn's 2.2 with LV kernel and my 3G is still timing out and crappy. My brother's Dx gets Fair signal during the storm, should i be worried about my phone? Ive wiped several times and i still get like 60 kbps down while he gets above 400 kbps.
So my questions are:
1. Is there something wrong with my incredible? Or is the X's signal generally better then the HTC's?
2. What ROM and kernel combination would give me the best battery life?
Its at :
Android System: 70 %
Display: 16%
Cell Standby: 14%
During the time writing this, my 3G has dropped at least 6 times. Is it normally like this during cloudy rainy weather?
Thank you in advance, and i Love the site by the way!

Lou's #4 is kicking ass with both his and warm.... fast and smooth, battery seems to be killer also.

Your going to heat this 50 times, but this is in the wrong place.
Nothing is (probably) wrong with your phone and its best to try several combinations. I am using MIUI to great success.

0) This forum is for discussion of development issues, not "which is right for me" or "how to use" issues... this should probably be posted in Q&A or General.
However, I hate leaving a question unanswered, so:
1) Signal strength is not related to which ROM you are using, and rather which radio. Look in settings->about phone->Software Info->Baseband version. The 3 current radios are 2.15.00.07.28, 2.15.00.09.01, and 2.15.00.11.19. Depending on your location, one of these three is the version you should use. BE CAREFUL - FLASHING ROMS IS VERY SAFE, BUT AN ERROR FLASHING THE RADIO WILL BRICK YOUR PHONE.
You could also try *228 to update your roaming as well.
2) This is constantly debated. Typically, horrible battery life is the result of an app running constantly or keeping the phone from sleeping. How does your awake time compare to your up time? Personally, I find that CyanogenMod 6.1 with incredibleK's kernel #18 gives me best battery life... I usually charge it every night to be safe, but can comfortably go two days of moderate use without draining the battery.

Sorry about the wrong forum, but im in the middle of flashing skyraider (3.5?) with King klicks #6. As for awake time and uptime, it used to be roughly the same. Give or take a few min. Ive speed tested on warm, and it still hasnt passed the 100 kbps mark Hows Cyanogen running for everything else?
Also, i cant get passed 1x on skyraider, it stays on "Turning on"
My radio is 2.15.00.07.38
Double check, my awake time is exactly the same as my up time.(Edit: Nevermind, i locked it and now the uptime is 2 min more than the awake time.)

That is a sign that either (a) you are literally using your phone 100% of the time, which will indeed suck batteries down very quickly, or (b) you have some app that is constantly asking for attention and wont let the phone sleep. By comparison, my uptime is 11+ hrs, and my awake time is about 3 hours. It's awake when I am using it, but it sleeps other times (can still receive calls/email/sms in this state). If your phone isn't sleeping when you're not using it, battery wil suffer.
EDIT: If you just rebooted, then it will of course be equal. You should check after you have been booted and running on battery (not plugged in) for a few hours.

No that doesnt work

Try a new radio. Legit, it will probably help a lot.
Research how to check an md5 sum before you actually flash it through hboot, but past that you're set. If the md5's don't match, redownload.
I suggest the 11.19 radio (The new EVO radio). 9.01 also worked well for me, but the EVO one works wonders. I also have a wannabEVO phone, so that might just be me.

REALISTIC battery life ???

I was just curious what you guys and gals were actually seeing from your batteries?
I have an LTE GNex that is rooted with APex ROM and Franco Kernel.
Everything i read is about all this fantastic battery life... im just not experiencing that. I did purchase francos app to keep the kernel updated and to support him. I am also running Antutu Battery Saver on Level 3. My phone will lose 10% an hour just replying to a few texts and sitting idle in my pocket. If i watch a few youtube videos or listen to some music itll drain quickly. Has any one experienced similar?
CPUspy shows that the phone spends most of its time in deep sleep... what is going on?

From the looks of your screenshot, it shows you have low signal. The phone could be dying faster trying to hold onto extra signal if you spend most of your time where the screenshot was taken

first thing i would do is get rid of that battery saver u dont need it and make sure ur on a current radio , mine and a few others battery posts are on frankos kernel thread page 747 . the first 20% OF my battery from full charge always drops fast than after that slows down . hope helps u

wow, thanks for the quick replies!
I thought maybe it could be struggling with a signal.. this house is the dang bermuda triangle of cell service... however with the same 2 bars of LTE im still getting decent speeds....
I am on the 4.0.2 radios only other ones i saw were the leaked 4.0.4 and from what i have read about them, they are iffy...
Thanks so much for posting a page number!!!!!!! i was getting worn out reading and finding nothing on his kernel page!!
I will ditch the battery app and see what happens with that...
I am also losing my OC... is this the fault of the kernel and the rom fighting to own the permission to OC ??? ill set it and check it a while later and ill be back to 1000mhz...
thanks again for the replies
much appreciated,
j

LTE will usually give you good speeds even with one bar. The problem is when the radio senses a weak signal the phone pushed more power to the radio in an attempt to catch and hold onto that signal

oohhhh that makes more sense then. so it could still be this dang house! lol
i will be in BFE west texas next week without a hint of LTE... ill put phone on CDMA and i bet my battery goes a full day then...
the Kernel Page only had 245 pages ... i didnt find the battery stuff... ill keep after it and see what i can come us with...
thanks again...

i have a gsm gnex and my house is also a very low signal area, 2 bars or 100 dBm is very good and the phone is constantly switching from edge to 3g but even with all this i still get excellent battery life. try switching radios like other said, certain radio are better at switching from 2g to 3g or LTE. im also using apex with the apex kernal. its the best one in terms of battery life, very simple and minimal but works great. there wasnt anything causing wakelocks.
did you check if you have any apps or process interrupting the phones sleep? 10% an hour seems more than just a radio problem but i could be wrong since LTE does use more power. try downloading better battery stats, its free, and will tell you what process or apps are waking your phone.

I would turn off lte and sync when not needed ...try stock rom and see how the battery life is...use it for few days then install a custom rom if needed

OK, So i downloaded better battery stats and found that i had a process that was really doing a number on me it was... "mobi.mgeek.TunnyBrowser" I did some research on it and found that it had to do with dolphin browser. I removed the browser, the bookmarks to SD, and the faster load... the process then went away and the battery percentages appeared to be more normal.
However im still losing battery really quickly. I unchecked some synced things that i dont use, browser, calendar, photos, music and wallet... hopefully this all helps.
I was sad to lose dolphin but i found Chrome instead... very very nice!!
I will watch the processes... i did not see anything that was waking the phone..
Thanks again!

How to reduce battery drain while using rom?

Hi. Battery drain in sleep mode is really good. Around 0.5 % an hour. But when using 3g internet, battery drain is massive, around 3% per minute. My friend was using his iPhone with similar usage to mine, his drained from 75% to 50%, mine drained from 73% to 20%!
I have brightness on low, GPS and Bluetooth off, and I am using radio 26.13.04.19 which is one that I have found to be good and reliable. Is there anyway to reduce my drain? It's way too much right now. Thank you!

3% per minute while screen is off means your phone isn't going into sleep mode.
I guess there's an app that keeps your 3G modem active.

No, I think you misunderstand. 3% per minute while using my phone (ie: when screen is on). Like I said, when screen is off, drain is only 0.5% per hour.

Try to switch to EDGE, I had it too before. The drain was caused by a bad and cell tower signal. By switching to EDGE the signal went better, same as the battery drain. Only uses 3G if you're signal/reception is good(above 3 bars).

you can turn off Wifi GPS BT and of course the screen brightness .
iyou need to activate sleep mode beacuse when in this mode you almost dont have battery drain ....

Jesus. I just spent 1 minute on facebook and had 4% battery drain! Using mobile network (getting 3 bars of 3g signal). Why does android have to do this to me. I'm jealous of iphone battery life

2-3% per minute during 3g session is pretty normal ,even I am having the same drain ,I have spent months and tried all the tricks in the book (uv script ,reduce CPU speed)to reduce the drain all my efforts have gone down the drain I think we have to live up with this sort of drain...

i agree.
i've given up trying to solve my batt issues. i've got icecoldsandwich 6.1. BT,GPS and WIFI is always on. cellular data is on WCDMA preffered. under volted, under clocked and even low vibration mod. screen brightness is at 10%. still drains at 3% per min when using the data. i've got a brand new battery from HTC service centre during this time and it doesnt help. i even started to think that my charging circuit was screwed up :|
got really paranoid..
but i guess the battery drain is pretty normal given the battery capacity

There are some build.prop tweaks that you could try. Related to sleep mode and hsdpa power collapse. Look through this page and add whichever are network and battery saving related (mentioned). Look through your current /system/build.prop and only add what isn't already there. If it's already there, just change the values.

To save my battery I have started to use Tasker, this is a profile manager. For example You can set up your phone to switch On Data and sync your apps every 30 min or more, instead of have it On all the time. There is a lot of options to set up your phone. For me it is working great and it helped me to lower daily battery drain. You can find other Profile Managers on Google Shop.

That doesn't help with the 3% per minute while awake.
And switching data on every 30 minutes often means that you can forget using apps like whatsapp and viber. Most of the time people rely on messages arriving shortly after they were sent.
Image your boyfriend/girlfriend sitting outside in the car and texting you "hurry up! we need to go!!" and you get that message 30 minutes later....
And consider using Llama....it's mostly the same as tasker but free

There is an app called battery calibration that can help with battery life. It helped me

Have compared battery drain with different radios? Some radios I have tried give better signal with higher drain. The M2 one I am using now gives a nice balance but it may differ for depending on your location/reception.

battery life

I recently bought a used nitro hd and unlocked it for use on t-mobile. I lose about 4% battery life per hour while in standby. bluetooth, gps, wifi are all off. cell radio is the only thing on. phonearena reports a 259 hour standby life, and at this rate I will get about 25 hours of standby time. and perish forbid I use the phone, when I can literally watch the battery percentage drop before my eyes. I lose about 1% every 2-3 minutes when using it. I have tried v20c and CM10 stable.
does this sound like a problem that can be dealt with somehow, or am I looking at a new battery? thanks.

Habe you tried disabling LTE? It may be because your phone is constantly searching for an LTE signal that it's wasting so much battery.
CM10 and V20c are not particularly great with battery life. You might try CM9 if you want to see if it makes a difference.

thank drumist. I forgot to mention I also downclocked the processor to 1ghz with cm10 with not much noticeable effect. in cm10, under preferred network mode, gsm/wwcdma preferred is checked. lte is not.I also lost a full 1% just checking that.

While in that same screen you selected gsm/wcdma, if you go to Access Point Names and switch it from ATT LTE to ATT you might see some improvement. Also, HO!NO!s Full Throttle seems to be quite good on battery life. It's CM9 based and it's pretty snappy. I've got it overclocked to 1728mhz and have been playing with mine almost constantly for about 5 hours so far today and I'm at 66% left.

You went back form pA 2.5x, eh? I'm currently running 1d 6hrs with 2hrs+ screen on time and at 14% bat life on FT.

That's why I've been playing with it so long today lol. After reading what you said the other day I had to give it another try. I do miss phablet mode though! What all have you done to it to get such ridiculous stats?
Also, I do tend to ROM hop a pretty good bit. I've tried every ROM in the Dev section except Liquid Nitro; PA just seems to be my fallback.

Left the OC at 1728. Left the GPU OC as is. I under volted -75 from 192mhz to 1026, then -50 up to 1512 and -25 above that. I leave sync off. Only have wifi on constantly when plugged in. I freeze Google Maps until I need it (constantly runs). Diplay-automatic backlight enabled-sample intervel 5s. Performance-memory management-allow purging of assets checked. And follow this guide for calibration: http://forum.xda-developers.com/showthread.php?t=1616598 ... I think that's about it. Oh, I also let it settle in for a few days before judging life of the battery.
EDIT: I also ROM hop often. Liquid Nitro is the only one I haven't tried, too. I love pA JB but the battery life drives me nuts (have a backup though). I'm lucky to get 8hrs out of a charge. I can't wait for thomas.raines to finish is LZ JB kernel. That's gonna improve things quite a bit.

Where do you set the uv settings? I swear I've read the entire FT thread but I must have missed it.

/ect/init.d/99ocvoltcontrol
/ect/init.d/99GPUoverclock if you wanna oc the GPU more which I've done but caused overheating.

thanks for the responses. I am trying FT and it seems better, but I lost 50% of battery with the phone off between yesterday and today. 50% with it off! what the heck?
