Hey all, I don't know if anyone has even noticed on their Evo's but on mine, the Android system usually eats most of the battery. I noticed there is a ton of processes under Android system that are running compared to like five on my Hero. I've never seen the core system processes take up more than maybe 15% of the battery, but right now, I'm at like 41% with 16m 6s of CPU total and 47s of CPU foreground. If anyone knows why this is or a way to fix it, please let me know. I'm on the first MR update. I've been able to get a lot of battery stuff figured out, if I can get the system to calm down, then I should be able to get even better battery life than my Hero.
I'm seeing the same thing, android system is at 96% battery use after letting the phone sit overnight. Never saw that on my nexus, this is strange.
Could be related to the fact that everything is syncing up, I just activated last night too.

Yeah, the system seems to have calmed down a bit today, though I also have the OC widget running to keep the processor lower during sleep. I'm guessing its helping, but I'm not sure if there is something else to get it down. I almost never even saw the System show up in usage on my Hero, now its one of the top contributers. I got used to having custom roms on the Hero, but so far all I need on the Evo is unrevoked. I know a lot of people around here don't like it, but I found I only needed a couple of apps that require root and so far love it. That OC widget really comes in handy.
maybe i can clear things up a little bit for you guys...what you see in the battery use section is distributed across 100% of the time since you last had it plugged in. if you notice all the percentage numbers add up to 100%.
if you plug your phone in and turn it on and off on you will see that android system is probably around the 90's thats because android system has used 90+ percent of the phone since you plugged it in....over time that number will lower, becuase other things will start using the battery power... what you see is a percentage based on time. not based on whats actually working RIGHT THEN AND THERE do you guys understand?
I too am having that problem and at 15% battery life warning - it still shows my Android system @ 40-44% usage after 8hrs of work.
I mostly text message all day long due to work - make phone calls and recieve calls from work every hour. GPS on for no more than 15min all day long to get direction when my keymap book doesnt help.
4g off, bluetooth off, background data 15 min only (gps) than off, gps off when not in use, mobile network (3g) off when not in use.
I would have figured my screen being on would have drained my battery life since I check text message every 10-15mins for 8hrs...
So went to work at 9am, 100% life
got off work 6pm, 25% life
I've done all the tricks, cdma only, force stopped a bunch of apps, goggle talk off, sync off, making sure maps/gps has been closed (forced or not)
still disappointed with battery life.

My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day
*facepalm* you guys don't get it....

check your hardware version there is a thread about different types of evos and it seems like everyone who has the hardware revision 0001 has really bad battery life. i would exchange your device.
Yes we know, Freelancerx, or at least I do. But after over 8 hours and the system is still using more of the battery than anything else is a little disturbing. Never seen that on any other device. I have Hardware 0002.
I have this same issue with hardware version 0002. I run Fresh 1.0.1, i use Netarchy-toastmod kernal, have latest radio. I have also tried Damage Control (did get slightly better battery life out of DC but not amazingly different)
after 7 hrs since unplugged my andriod system is at 39%, cell standby 28% phone idle 20% display 9%.
i dont have bluetooth, wifi or 4g on. I use juicedefender+ultimate to turn off apn when screen is not on. I use set CPU to underclock when i am unplugged and go down to 128 when screen off and i am Stilll lucky if i make it all day with moderate usage.
Every day it is the same andrioid system is around 40% of the usage for the time it was unpluged.
the following is listed under included packages (not sure if this shows the same for everyone or if it shows what packages are running)
BRCMBluetoothService - Bluetooth is not on so if it shows packages running this may be an issue
Sync Feeds - I have all android syncs off and mail at 6 hours
settings storage
Rosie Utility
Acounts & syync
Account and sync settings
settings
HTC Widget Download Manager
Network Location
Setup
HTC Checkin service
Checkin serivce
VPN services
Android system
Wonder if there is something to the android system on these (ie something not turning off that should) or if we are all just crazy and happen to get the same results.
I had a hardware 0002 model and often experienced the same thing with high system % usage.
My phone was replaced, due to a screen issue, and now I have the 0003 model and seems system % is much lower so far.
I haven't installed any system update yet, so I am on the first original release rom (not rooted yet).
Going to be testing it for a few days before I update and root, so I can make a fair comparison between the original and current oem's.

I think everyone here understands this. the question i think we are trying to figure out is why with similar usage and configurations some people get 40-60% android systems usage while others get 10% over the same period of time.
Android system is way too high.

Yes but if it is configured in an optimal way then android system is always beneath cell standby and phone idle.
For example, today after 15h 28m 23s since unplugged I have...
Cell stanby 38%
Phone idle 37%
Android System.....12%
That is with background processing with auto syncing every hour or so.
My battery life has been great with the current set-up, but in the past 3 hours something screwy happened. I basically went to a function and I turned off BT, Wi-Fi, Mobile Data and GPS. Only thing on was the cellular network and I swear I didn't use it for more than 5 minutes. The battery was at 98% before leaving, now in those 3 hours it came down to 50%. What the crap? The only thing I did was to play Super KO Boxing 2 before leaving for about 5 minutes(It still shows its battery usage as 20% but no option to force close, so I am presuming it isn't running). I did open Maps and HTC Locations(Sense 2.0) for 2 minutes but I closed it because I didn't need it anymore, I also disabled GPS right after that. Now after all of this(game and gps stuff) I had 98% battery. Yet 48% of my battery went into thin air just like that, my battery use is Display: ~40%, SKOB : ~20%, Voice calls: ~15%(About 3 minutes), Cell standby ~2%, Wi-Fi ~4-5% or something like that. These are from memory since I turned it off and kept it for charging.
Any ideas what screwed things up?
Edit: Just noticed you are already familiar with the battery %age lcations.
From what you describe, it sounds as though there were some apps running in the background, slowly om nom nom'ing your battery. I daresay there are a few apps on the Android Market and elsewhere that can tell you what services are running at any given time, so you could get one of those.
If you're after ensuring maximum battery life, however, your best bet is to shut down the Desire, then fire it up again. That way, you can be sure there are no background services to drain charge. Couple that with lowering the screen brightness and display idle timeout (not to mention upgrading to Android 2.2), you should be able to go at least a couple of days on standby.
Sounds like one of your apps is keeping your device awake. I'd suggest getting app monitor like SystemPanel and run the monitoring for a few hours to see which app is consuming the battery.
And get WatchDog. It will notify you if there's any app that use the CPU more than 20%. You can set the percentage yourself btw.
All right, I'll be formatting the phone and flashing the RCMixHD v8 ROM(Was using v7) and then see what happens. i can bet my life that it was either HTC Locations or Google Maps screwing things up.
Hi guys,
I'm all new to Android, having previously used the TG01, moving to DHD is such a right decision and honesty think i may not use winmo ever again.
However, I notice something weird (or at least I think it is) one of which is my free Ram at boost is only 3xx Mb. Considering I have 768 Mb RAM, am I supposed to have around 700 Mb at boot??? or is that the way Android work??. Also note that I use Advanced task killer to see that number since I don't know where to know my available free Ram (noob?). Do you guys have the same amount of Free Ram at boot?
Lots of apps like yahoo messenger, internet browser.. which I do not how to properly close them (I press either home or back keys). They keeps running in the background and even after using advanced task killer to close them, they are amazingly still there. Do I suck or again is it how Android works.
Also, after 3 full charging cycle, unplugging at 7 am, having around 30 mins gaming, wifi on all the time but sometimes not connected, 3g all the time, Yahoo messenger running in background, some mails (not automatically syncs), messages, calls and about half an hour web surfing, it rests in peace at 4.30 pm. Is it normal or Do I have faulty battery. Forgot to mention I set back light at 30%.
Again, if the thread duplicates please accept my apology. I did do some search but have not found info I need. I'm all new to android so any help would do.
Cheers,
Hi,
This is how Android works. Task killers are a waste of time, your phone will use more resources just loading the apps back into memory.
As for the battery, do you need to keep wifi on all day? There is your problem. Turn it off.
Try JuiceDefender from the Android Market. You will certainly notice a battery improvement using it.

Removed task killers and installing Juice Defender, hope to see improvement there.
Well,the DHD in all its awesomeness is always gonna miss one thing:Good battery life.Not because it sucks much power or something,but the battery is the smallest I've seen on a high-end device,and,considering the huge screen(which uses from 60% up to 85% of the battery),it won't do really well.However it's not so bad either!I for one,after some charging cycles(I have it about a month now)get much better battery life.Taken off charge at 8am,usage varying depending on the day(eg I don't use it much at school),I still have enough battery at night(around midnight)to play some games for a while and listen to music.Brightness is always full!Can't accept lower with this screen!

No No Noooooooo
With JuiceDefender activated, wifi on occasionally, 3G and Yahoo messenger all the time, 1 hour game, about 30 mins calls and some text, my phone was dead after 10 hours.
Really depressed, I read in battery thread this trick:
Quote from santu001
The official battery trick from HTC tells us to first charge 8 hours or more, then 1 hour while off, boot and let it settle for two minutes, turn off and charge another hour.
I'm on the fourth day since i've done this. After i did this, i deactived all appkillers (advanced taskkiller i.m.c.). Letting the system balance itself as quoted in one of my earlier posts.
I'm on the fifth day after calibration now and have 35% left after 21 hours since last plugin. I didn't turn off anything. I can see through current widget log it's still been very active from -3ma till -30ma in standby, no spikes though. For now i'm getting increased batterlife.
Default phone battery monitor results
Juice left 35%
Screen 39%
Mobile standby 20%
Phone inactive 18%
Speach 7%
Wifi 7%
Android system 4%
Android OS 3%
com.htc launcher 2% (Even though a lot of apps still loaded in BG)
Does anyone try that one?? Does it really improve your battery life (i do not understand the logic though)
keep in mind also, 250mb of ram is dedicated to adreno as vram, so the device only has just over 500mb of usable ram

Be patient young Padawan!
On my Diamond(good old days...well,maybe not so good! )the situation was about the same and it took the battery a little more than a month to give me its full potential.This might be the case here too.Don't judge it just yet.Except it's faulty of course!
Anyway,there is always a chance that a badly coded app is doing something nasty with your device.You might want to install system panel(very useful app,both one of the best task killers I've used and a really good system monitoring app) from market.It will show you if any app is using your ram or cpu too much.If one does,try uninstalling it and see what happens.
Hope you solve your problem!
This seems strange.Yesterday after upgrading to gingerbread ( with the RUU because the OTA didn't work for me) I got a huge battery drain.Over the night I got a loose of 40% and now only 3 hours after unplugged and lost 20%.
I only took a few pictures and a phone call.
Only few apps installed since i got this rom since only yesterday.
Anybody experienced this and is there a fix?
Hello,
I can confirm this.
I have also a high battery drain with ALL Android 2.3.* ROMs.
I use the recommend Radio for each ROM and I've checked the RIL to be sure the Radio is correct. But doesn't matter, current in StandBy is between 30 and 50mA.
Only if I turn off WLAN and Mobile Intenet, then I have normal values between 3 and 5mA.
With FroYo I can leave WLAN and Mobile Internet enabled and I had 3-5mA in StandBy
It could not be an application, because I've tried this with a fresh install without Google account to avoid the installation of external apps.

you'd have to edit the build.prop and change the rescan time from 15 seconds to 30, 60, 90 or 120 (or whatever you perfer the rescan intercal to be at)

Try resetting the battery stats by doing the whole charge, lead out, charge, turn off, charge etc. thing.
Also, whilst not a stock RUU I did find it took a few days for the battery drain to calm down a bit. First instal lowest was around 50mA but adfter a fe days it went down to 4-5mA.

What does that value do?
Is that the rescan value of WLAN?
The current stays high even if WLAN is off and mobile internet is on.
Only if both are disabled I get a low StandBy current.

Yes I know this, and I've tried this every time I was flashing a ROM (I mean reset the battery stats)
After a few days? How many days do you mean? 2, 3, 4, 5 days?
@both
But why this problem does not exist on froyo?

Varies but on average I find it takes about 3 days to settle to a point where I see a consistent drain.

Unknown. It's not 100% due to GingerBread as I've only seen a handful of people complain of this issue (relatively speaking). I see more people saying how much better their battery life is after the update than saying it's poorer.
Doesn't help I know but makes me believe that this is maybe a Network / Radio issue in that the new Radio with GB does not play well with the Network. We had this a few times on the HTC Hero.
Ok...i have airplane mode on for about 2 days.in those 2 days i almost didn't use the phone and got only a 7% lose.As soon as i used the camera(recorded around 15 min) it got down to 50% .
I will test it tonight widought airplane mode on and see the resoults.Also wifi seems to a lot of battery in comparance to froyo.

I haven't noticed these problems with CM7. I got 2.5-3 hours per 1% of drain in standby using juice defender.
If you are finding that turning off data etc is fixing the problem use juice defender. Even the free version will help a lot as it will stop your phone using data willynilly and instead turn it to a periodic sync. With the paid version you can have it stop all together during certain periods or increase doing certain periods. Aka stoping at night and extra during busy hours at work.
Should be a good fix, though it is only covering up the underlying problem still.
Can't really recommend the app enough. With it my phone only uses data when I tell it to (like opening facebook app) or periodicaly to sync and check emails etc. I do use the paid version though for the extra features.
totally agree. i have been using juice defender for about a week. its been a big help. just bought the ultimate a few min ago. going to start customizing.
sorry that i dont have any data yet to back up my statement. maybe in a future post.

im using Leedroid 3.0.3 and i dont get any such battery drain..
tbh im getting a better battery life from GB than from froyo..
on standby currentwidget shows me between 4-7ma with wifi on... with a peak once in a while..and i lose abt 1 to 1.5% per hour
with wifi off i get about 3-5ma..
i dont use mobile data much so cant really comment on that..
try calibrating your battery and try changing the scan interval in the build.prop... i normally keep it at 90...
i never used any battery saving apps, so cant comment on their performance either...
go to wifi advanced settings and untick Best Wifi Performance... that also helps a lot!
hope you get your problem sorted
Thank you all for the help
The issue was not with gingerbread...I just left my phone one night with wifi turned on and lost 40%.But still when I was on Froyo wifi wouldn't loose so much battery.Now I loose almost 2-3% every 15 min if surfing the web with wifi.
And about changing the scan interval in the build.prop...How can I do that?Do I need root?
I'm also having battery problems, but mine are a little bit different, if I'm on wifi it uses between 3 to 5% with a peak now and then. if wifi is off and I'm on 3g, it's between 5 and 500 ma and you see only peaks if you check currentwidget. anyone a clue? working on ARHD 5.1.6 now, but problem was there since version 3
I have battery problems also, my battery dries after 1 day of use. For example this morning, I unplugged my phone full from the charger at 10 am. I went into town, listened to about 20 minutes of FM radio. When i stopped the radio, I still had 98% left of the battery. OK so far. After, I talked for about 5 minutes, sent 4 messages and played for about 15 minutes. I arrived home at 2 pm with 75% of battery left. That is 25% in 4 hours.
I was on 3G, but with Mobile network off. BT, WIFI, GPS off. A few days ago, I tried running the Battery Calibration app, but seen no improvements so far. My phone is routed, 2.3.3 and has Android Revolution HD 5.0 RC1 ROM .
I expected the battery not to last for long, but this is ridiculous.
Help me, please!
I don't know if that will help, but I sometimes switch to 2G networks as HSDPA is using quite a lot the battery.
I have a DHD running 2.3.3, and it's definitely the mobile standby bit which is first in the battery use screen (33%). It was true before 2.3xx but now it's a bit more - annoying in other words.
I have to admit, having to switch to 2G networks is a bit of a pain in the *ss, so I'll check if juice defender give me some good results tomorrow and will post a feedback there.
Maybe try AR 5.1.6. + he recommended radio. It works wonders. the battery life is improved a lot...
malik
Juice Defender works very well - with basic settings I still have 35-40% of battery by 7pm.
furstrated with the battery life...
hey guys,
so this is my first post and all i've done up until now was to read... i'm afraid not real solution has come up.
i have:
Leedroid 3.1.2 with the recommended radio and i ran the script for Full Wipe 1.5 and cleared the battery stats, i did a fresh install and then didnt restore from backup - just installed everything from scratch. i hoped it would be ok, but when i woke up to check the current widget log, i saw that in the middle of the night he climbed to 150mA and stayed there draining about a 1% of battery in 3-4 minutes (!!!)
what can i do? 'where is my droid power' shows only HTC Sense at about 3.8%
please please help... thanks!
So I've been running the RCMix3d for a week or two now, and everything has been great. Generally, after 16 hours or so I have 40% left on my extended battery (both on stock and RCMix3d). Now for the last two days, I've been getting this extreme battery drop where my phone dies in something like 10 hours.
I have no idea what it is, I thought it might be the newest facebook update (and facebook in the past was a CPU hog), but this time neither facebook nor any other offending app was appearing in the "Battery Use" chart. Everything seems completely normal, my battery use percentages are just about where they were when everything was fine. Watchdog is not showing any apps exceeding over the default threshold.
What can this be?!
Thank you
Run a dumpsys power command from a terminal. I bet you have a wake lock.

Too bad I wasn't patient enough to wait. I have reflashed stock already. Out of curiosity, what could cause a "wake lock"?

something like that happened to me ( battery dies quickly ) , and the reason was phone is searching for network all the time
