I let my phone discharge fully till it turned itself off!
Charged it for 4 or 5 hours.
Now I used it to make 3 short calls (5mins each) and send 10 or so texts, and surf for about 5 minutes, use google sjy mpas for 5minutes, showcase some video to some friends 2mins, general messing 10mins altogether.
Phone is up 40hours now (since charge) and still at 80%. I am very impressed.
I put it to airplane mode between 12am and 7am though as I don't like to be woken by drunk friends texts at 2am etc. (it happens sometimes).
I think those of us (me included) who slated the battery life originally didn't relaise we were using the phone non-stop pretty much for the entire day, trying out all the features on it. I doubt the first week of use will be "typical use" for ANY user
Happy Days
My battery on day one seems fine, 12.5 hours running so far, screen at 100%, everything on automatic syncing (and I mean everything, Weather, Twitter, FB, Gmail etc), continuous WiFi connection throughout, plenty of "first day" playing around and still sitting at something like 20%. With a few more charges and more typical use will last a day just fine, which is all I ask, since I always charge my phones overnight...
When i got my phone i let it run out as it had half power, i overcharged it a few hours then let it die, then i do the same again but not overcharge it and let it die. Now i charge it when i need to but i seem to be getting 3 days worth with usage out of it and i use gps, web and have things on auto. Seems to be much better than when i first had it as the battery didnt even last a day but now its past 2 days.
I assume with newer firmwares etc this will improve
My battery life seems to get worse. I charged it fully ... it has been on for 6 hours and I have put 3g on for a while (1hour max and i barely have used it) and my battery is already 60% ... is that poor?? This is my second phone as well!!!

I thought a full charge only required 3 hours..?
Anyone having surprisingly short battery life go into the phone keypad and dial in *#*#4636#*#*, when you key in that last * you will be taken to a testing menu (I've added a contact with this number and when in the dialer I can long press on the number as select edit number before calling to take me to this screen)
In this menu there are options to see phone and battery information as well as usage statistics for apps. The best battery option is "battery history" this shows you what apps are using your battery for various things such as network and processor usage. You can see this data for since you last rebooted your phone, unplugged it or for the whole life of the phone.
The first important part is "other usage", "running" shows you the percentage of the time your phone has been awake and doing stuff, "screen on" is the percentage of time your screen has been on, the difference between these two is when your phone has the screen is turned off but the phone is still working such as when syncing. Ideally you want these two percentages to be as close together as possible but it depends on how much syncing you have going on automatically in the background. If your running percentage is at or near 100% then an app is keeping your phone awake and using battery.
Next we have "partial awake use", this is what as been running in the background when you have the screen turned off and any apps that process or sync in the background would be listed here, the longer the bar, the bigger the drain on your battery. On my phone now the biggest bar by far is android system but it is still only small.
With "sensor usage" this is what has been using your sensors, games that use the sensors will feature heavily here.
"Gps usage" is again pretty self explanatory, whatever has been using gps.
"Network usage" was a real eye opener for me, I found out that an app was downloading megs of data all day and dwarfed all the other bars and was the reason for my bad battery life. Here the blue part of the bar is download and the red part is upload.
And lastly "cpu usage" on mine these are all practically non-existent but if anything is using massive amounts of processing it will show up here.
I only found out about this the other day but it has helped my battery life substantially, I used to take it off charge in the morning and be down to around 60% by lunch time, now I'm at 98%. I did this by uninstalling any apps that used too much battery and that I didn't really use very much as well as the vampire apps that were running and syncing continuously in the background, I also reduced the frequency at which some of my services such as stocks, email and weather synced, and used it on a low brightness when possible.
This is my first android device and I can now happily use it without the fear of running out of battery before the days end
Wow, thanks andybut85, that was a very informative post!
If you download Spare Parts from the Market it gives you access to the same info - instead of 'dialing' to test mode.

My biggest is "Calendar" (54mins from Boot, compared to 1min for Andriod System!)
What Calendar could this be? Im syncing from Google Calendar, so will it be that? If so, wouldnt my email syncing show up as constantly on too?
Or could it be some other App that is making it run constantly?
Any help gratefully received.

Have a look for "Total in all time" with mine the calendar is roughly half that of android system, it could be that recently your calendar has had to sync for a long time, this could be a one off or if it's still high for the total time it could be a deeper problem. You could also try rebooting and seeing if it occurs again.

I'm still having problems with battery drain.
My Desire will not last a day
Installed Juiceplotter to find out when and why my battery drops so fast.
See attached image.
The battery drains very fast when i USE the phone, so when the screen is on. (20% in one hour)
I have two push email account activated, one with the HTC Exchange, and one with TouchDown.
But that doesn't explain the drops when phone is active.
Anyone else having this kind of batterydrain ?
I have positive "story" about battery too. Im on second charging. Saturday at 1:00 Im unplug it from charger and now 34h later Im on 7/10 battery.
Im make few calls(cca. 10 calls long 1-3min), few times(cca. 3-5x) check emails accounts(4 pop3 email accountes), quick test sygic navigation, little search on market(install calendar widget and some other app), and play few levels of Teeter...
3G is turned ON
GPS, WIFI is turned OFF
Also automatic sync is for most things disabled or setup to sync 1x per day...
Hmm Can't say I'm impressed by my battery life... it dropped 20% overnight..
I''ll keep an eye out on what's running and see if i can fine tune, but turning things off seems to be a bit pointless as it is made for use not just sit on a desk being pretty.

i got great battery life at home over the weekend connected to my wi-fi network.. i have a feeling its the crappy edge reception in my office thats eating into battery life during the week..

yep, that sounds highly plausible. Bad or weak connections to the network (especially mobile internet connections) will really drain a battery as the phone needs to use more power to maintain adequate connection strength.
you can check your signal strength in the "settings / network strength" section. I notice in good 3G areas my connection is -95dBm or higher. At work (which is in some sort of black spot in Dublin) I only get EDGE connection and my signal strength is about -80 to -85dBm. I bet this makes a big difference to battery life, especially if I try browsing or data connection.
my signal strength at work is -91 dbm...
i'm guessing bigger numbers are worse?

spare parts showed me that "media" was using the network a lot, bowever i cant work out what this corresponds to, it says DRM protected content storage, download manager and media storage. shows as having downloaded several megs
i use spotify for music, anyone any ides what these could be?
thanks
only guess but i'd say its spotify.. i have used servcies like that in the past on my pc.. and they sometimes have a lot of downloading going on that you dont even ask for!... worth checking out..

yes it could be, but spotify also comes up as a separate user of resources and i tested it since unplugging when spotify wasnt running and "media" still comes up as the biggest user.
makes me think that its not spotify
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.
Unrooted Evo
My crappy AT&T Razr lasts me 2-3days with text message + call + 1.5hr of playing Bejeweled a day

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.
Why in the world is my battery dropping so fast? and why is cell standby taking most of my battery like My phone went from 55-50 within 10 mins of just sitting there. Can anyone help shed light on this?
^^^^BUMP^^^^^
Try going into Settings -> About Phone -> Battery -> Battery use
It'll show you a breakdown of what was draining the battery.
I have the same problem, I have tried different roms, kernels, wiping batt stats, calibrating the batt...nothing. The only idea I have left is to get a new battery. Its frustrating because I feel like it wasn't wasn't bad before I tried flashing cm6.
I remember digging into this issue on another phone with cm6. If I remember right the phone.apk or dialer.apk (I believe it was this one) was keeping the phone in a partial wakelock. That in turn, ate the hell out of our batteries - not everyone had the issue though so we figured it was just a matter of how different HW/SW revisions handled the ROM and/or kernels. Basically we knew what caused it but not why it was happening.
As for the cell standby all that means it that out of the entire time your phone has been booted, cell standby it the most active. If it's at 70% that doesn't mean it used 70% of your battery - just 70% of the total active time.

Mine had that issue because it kept going 3G > E > 3G > E. Soon as I turned 3G off when I wasn't needing to use it that helped a lot.
3G and wifi consumes battery a lot
Make sure your phone isn't constantly syncing, make sure that it's only syncing at certain intervals.
Also, download JuiceDefender because this app will customize your options so that when your screen is off, your data will be turned off and will only be reactivated when you unlock your screen (plus the certain intervals that it will turn on to do some email and other syncing)
and also make sure you have this option disabled "Flip the phone to make it silent" , from what i have read they said it will always keep the phone partial awake and yes like others said make sure your sync intervals aren't too short like checking for every 1 or 2mts for changes/updates
Well, I searched the forums and haven't found anything specifically for the Defy.
Coming from an HTC Wildfire, which under similar usage had a battery drain split of 30% Cell standby, 30% wifi, 30% system, I noticed that with the exact same usage, the Defy has a cell standby use of over 50% every single day (right now its at 54%). Funny thing is, it ALWAYS says on the battery manager that there is no reception for exactly 50% of the time. This is bull, because I live in central London, and I rarely get less than maximum signal displayed.
Also, I'm on WiFi almost all the time, (WiFi at home and at uni, so the only time it uses 3g/HSPA is on the way there and back, which is less than half an hour).
Has anyone else had this? Any idea what may cause it? I feel like I should be getting better battery life than what I'm getting now, it lasts under a day.
Setting your mobile to 2G only should save you a little power, also be careful with task killers as they can kill some system processes that reduce battery usage, restart you cell to get them back.
I can get 3-4days of battery life with lite use.

Thanks for the reply.
I'm not using any task killers, so that shouldn't be a problem.
Any tips on how to switch it to 2G? I can't figure out anything in the network settings.
I'm just thinking that there may be something wrong with my radio receiver/transmitter to be using so much power in comparison to wifi and phone idle (well, compared to my last phone).
You can switch to 2G in wireless & network settings, mobile networks, select network.
But I am already using 2G and I have the same issue, maybe it is a little better than 3G, but still the "cell standby" is using most of the battery.
I saw the battery usage on Galaxy and there is only a very small usage for "cell standby" only about 10%.
i dont know what's going on with your cell,but WIFI is actually the biggest battery taker
,and the strength of signal power really do something to your WIFI chipset battery usage
what about a better WIFI signal....err i tried to change my cell into 2G or even outline
it doesn't work too much as i want
so maybe think about the WIFI problem?
Well, right now the main drainers are as follows:
Mobile standby: 44%
Go Launcher EX: 25%
Wi-Fi: 15%
Display: 15%
Phone idle: 2%
I was in my place all day today, with the phone permanently connected to Wi-Fi, so 3G was not in use. I get very strong cell reception in my place so I either have a spectacularly efficient WiFi module, or a power hungry cell radio. Or the measurements the phone is taking are wrong.
On another note, Go Launcher seems to be taking up a large percentage since its last update (yesterday or the day before), so I'm uninstalling that.
if WIFI should not be the reason and you've uninstalled the update task,i think it should be OK...but what would you do if that doesn't work?
the battery usage of standby was still more than 40 percent,yes?
why dont you download another battery monitor software....?
i'd have a longtime software error in my HTC G3.....it alwaws show me 45percent remaining battery ....
in setting/wireless & network/mobile networks/select network --- it's good to set 2G or 3G do not let automatic because it switches from 3G to 2G if the signal drops. Set 3g and see how it is.
(sorry for english)
mine on automatic in 6 hours battery dropped to 50% in standby, and now it is set to 3g all the time
mine:
Mobile standby: 40%
Display: 22%
Phone idle: 21%
System: 4%
Games, Adw Launcher EX and os: each 3-2%
when in games mine sometimes freezes and i must get out and restart the game???? i dont no why and i dont no if it is ok but ....
Thanks for the input everybody. So all of today I used the phone pretty sparingly at home, and it's been constantly connected to WiFi. Distribution is:
Mobile Standby: 56%
Wi-Fi: 19%
Display: 12%
Phone idle: 9%
Android System 2%
Under Mobile Standby, it still says "Time without a signal: 50%" even though it's definitely had perfect reception all day. I don't know what's causing it to report incorrect numbers :/
Anyway, I switched from auto to 3g auto (I tried 2G, it didn't seem to work properly, Google wouldn't even load).
I guess I'll just ignore it :/
Edit: When not on wifi, it seems to switch between 3g and HSPA quite often. Could this mean something?

just like what <stapuv>says when your cell drops any one of the 3G or HSPA singnal another singnal will be switched...it'll use more power for changing network frequently.....but i dont no if this could be the reason for your situation...hmmmm
From my reading the 50% without signal is just a software bug, and can be fixed by toggling on aeroplane mode turning of teh screen for 20 seconds or so and then turning of aeroplane mod when you notice it's happening. the 50% will soon decrease. I too believe that cell standby is using way to much on my phone (always 45%+) even though im browesing the web facebook or playing games for larger peroids of time and those apps don't even show up on the battery usage display and if they do theya re only 2 percent or less.
I have a question for you guys :
I get
46% mobile standby
43% phone idle
10% voice calls
3% display
is this 43% phone idle all right? Doea it mean that 43% of the battery have beed drained by phone in idle state (so maybe not sleeping?) or it means that from all the time phone was idle (asleep) for 43%?
I guess mobile standby use is about the same on everyones phones. That's what I wanted to find out!

After Go Launcher EX latest update, the battery seems to drain a lot faster during idle/standby. Removed that and standby battery usage is better.
Just thought I'd add my finding on this.
My Defy regularly showed Mobile Standard over 50% - but also time without signal was always double the time that the phone had been switched on. For instance if the phone was switched on since a reboot for 1 hour then mobile standby would show the total time as 2 hours but time without a signal as 1 hour.
I had always been running on a battery saver profile (in froyo I was running the custom battery profile) & after every reboot the mobile standby bug would show.
Yesterday I changed my battery profile to the Performance mode & after several reboots the bug hasn't shown up & now the mobile standby shows the total time correctly & zero minutes without signal. The %age use has dropped to be more in line with wifi at around 32%.
I haven't noticed any difference in battery life so as mentioned in a previous post it does look like some sort of bug.
A percentage is a proportion.
Just because it's higher on the Defy, that doesn't mean the mobile standby is using more power than it does on other handsets, it could just mean everything else is using less.
There's no point comparing your Defy's battery usage to any other handset apart from another Defy.

OK so after a few days of having no issue I rebooted the phone & the "bug" came back today so I guess it wasn't to do with the battery mode as I then put it back into custom battery mode, rebooted the bug went away.
Haven't noticed any difference over the last few days so I'm not going to worry about it.
I have found that DEFY is getting the readings wrong!
Here is how I get this:
1) fully charged the battery
2) started angry birds.
3) ~2 hour later, battery dropped to 60% and usages was as follows:
mobile standby 49%
phone idle 40%
display 4%
angry birds 7%
WTF ?!?! it should be : angry birds ~ 80%
This mettery is tottaly useless!
Personally I couldn't care less what the battery usage breakdown says. In my case 1% battery can standby 1~2 hours or use 3~5 minutes. That's pretty good for me as a charge can last 2 days.
Hi.
Could someone with this "bug" or "battery problems" do a test for me ?
A few hours after you've last charged your phone (or connected to USB) and being sure you haven't rebooted your phone recently (24 hours or so), do the following:
(My phone uses spanish language so the names might be different ...)
Dial *#*#4636#*#*, and choose battery history.
There, choose "CPU Use" and "since last charged".
What are the 4 or 5 main processes appearing in that list, and what's the CPU time they've used (you'll find that by "clicking" on the process' name) ?
Sometimes the battery works great, lasts a couple days. And sometimes, I get strange spikes where the battery drains extremely quickly (see attached images).
I have tried:
1. New device - I swapped my unit yesterday
2. Hard reset - restore all factory settings (and erase everything) off the phone
3. Battery cycle - i.e. let the battery run out entirely, recharge it from scratch
I have also tried diagnosing the issue via the stock battery app, GO Power Master, and BetterBatteryStats, but I don't see anything out of the ordinary when the battery usage spike occurs. Maybe there is some process running wild, but it doesn't seem to do anything...
Has anyone had similar issues? The only non-Google Play store app I have installed is Visual Voicemail - the apk I downloaded from this board.
You have tried everything I would normally suggest, but might have noticed something. Your sharp drop coincides with that red band on your signal bar. The red part signifying no cell tower signal. The sharp drop seems to start there. Is your phone stuck searching for cell towers when it has already re-established a signal? The earlier dip in the battery also has a red bar under it.
Also battery performance is not linear. If you are at 50% after 24 hours, you will not necessarily get another 24 hours. I am alwaysfinding myself at 50% after 18 hours and think, "Cool, I've found the right kernel" but sure enough I'm still plugging it into charge at 24 hours!
I know you say you normally get two days (which is very good) but this is all I can think of.
I use a powerful automation app called Tasker. With it you can set any phone setting to any phone condition. I've just checked, and it is possible to set a profile based on signal strength. With this you could specify a weak or no signal to do any manner of things, from play a notification sound, to turn off 3G and auto-sync. Set an exit task and it will also turn 3G and auto-sync back on when signal strength is healthy again. Might be worth a try.
Edit: If you have root access, Tasker supports the app 'Quick Boot Plus' as a plugin. With this you could set Tasker to reboot your phone if it is out of signal for more than 'x' seconds. I know it might not be very practical, but it would tell you if you we are looking at the real culprit.
Another edit: Scratch that. You could set Tasker thatif it sees no signal for 'x' seconds, turn on airplane mode, wait 'y' seconds, turn off airplane mode. No need to buy a plugin.
Thanks, wnp_79 - appreciate the thoughtful response!
Yes, that's a good point - there is a drop in battery starting with the red line for the signal. I take the subway to/from work in the morning and evening. But I don't see any problems connecting after I get outside (i.e. it doesn't seem to be searching for signal).
Perhaps next time I can try setting airplane mode on/off when I notice the battery draining quickly - and see if that helps the issue. If it does, clearly it's a signal issue.
I like the Tasker idea, I will give that a try! Thank you for the suggestion.
I wasn't by any means expecting another 24 hrs, but that drain of "50%" occured over a span of like 3 hours... with no screen usage (i.e. the phone was just sitting next to me at the desk, supposedly "idle").
Whatever you do, don't cycle your battery deeply unnecessarily.

Thanks tsleng, will keep that in mind.
I guess I am surprised other people haven't seen this issue. Maybe it's something specific to my software...
I've got this issue but it's down to my signal. At home it's fine and battery last's me well but as soon as I get to work my battery starts to dip due to Vodafone having poorer signal. Bad signal is killing my battery too bad we can't change radio's as of yet due to no S-OFF.
what happens when we can s-off? i mean what adv will we encounter regarding with the issues that we are having?

Well S-OFF, we can unlock bootloader without having to use HTCDev meaning we can revert back to stock easily and without it tampering the status. We can lock it back to it's original state.
We can flash kernels without having to use fastboot.
We can flash radios. By flashing other radios we can improve our signals if one radio is bad, an improved signal is friendlier on the battery.
I get a weird spike too but mine causes the phone to die. Also mine was done overnight when I was sleeping. (see attachment) I'm not really sure what I can do. I hope this was a one time problem...but i'm not so sure. I'm still under warnty and this is my second HOX

You have the LTE version of the one x Maybe they can help you there:
