Now, I know that it depends on what programs are running, like... whether you have any minimized or in the background, but on an average 1500 mAh/3.7V battery... what is the amount of use time that one can expect...?
Let's start a thread on this subject... listing the type of battery, approximate age of same, the names of the files/programs you run & use in a given day, and the amount of hours of overall use you get before you have to recharge or switch it over to a new/fresh battery. This way, we'll all have a better idea as to what programs really drain the phones, such as when you leave the WiFi and/or Bluetooth "on" all the time - waiting to be used (a sure guarantee to have a dead battery in a matter of hours).
We can subtitle this one under "The Cost of Staying Connected" (not including air-time charges or monthly fees).
i think my battery life is terrible... but its understandable. usually i run wifi and phone all day long.. the only reason i run wifi on all the time is because i have a feeling everytime i don't... somehow i get charged for using evdo (from bell in canada)... but i dont?? its really weird because i used to always get these random charges.. but ever since i kept my wifi on all day everything is all good. i have the original battery that came with my ppc 6700.. and i use the phone around 40-70 minutes of talk time. no real apps running but a few games of solitaire here and there. but if i were to talk non stop it only seems to last like 1hr
my battery life is like 10 hours and i always have to charge it when i get home from work or school or ill be doomed the next day
Since upgrading to WM6 (thanks helmi), my battery life has found NEW life. I used to have to charge it everyday: no wifi, 50% brightness, screen off in < 1min, etc. Since upgrading, I can run it at 100% brightness, screen off in 2min, and I don't have to charge it every day.
This is with the factory battery, and an eBay replacement sometimes used.
always running: freestyl (flashlite), sms threader, mbutton
phone is usually locked with s2u2
most use it usually gets is me checking the time
update rom from verizon, .net 3.5
ever since i updated the rom, it seems like i only get <24 hours per full charge (battery purchased less than a month ago)
w/o wifi or bt i get about 3 days however it depends on what version of windows are you running have you guys updated to the new 6.1 or 6.5 biulds?
My battery life its very short but, i use my apache with core play at my car with my kids plus the wifi, and blue with hand free, soo i've to conected every day, and i'm use 2batterys
original battery... i got 3 days on standby.. and 2 days in normal call usage...
but
with wifi my battery gets drained to the bone in 40 minutes LOL
thats all =D
About twenty minutes. I know I need a new battery >_>
... that and that I'm surprised I've got over 240 hours clocked in the lifetime call timer.
Using a 2600mAh 3.7v Battery
I had my extended battery for about 2 months now.....
TCPMP:Battery life is close to 5 hours on the lowest brightness level using headphones & on speaker mode I get about 3 1/2 hours.
Making Calls: I sometimes spend about 2 to 3 hours on the phone & that leaves the battery to about 70% or 60%.
Wifi: I don't use it for a very long time, but when I do it could be about 1 hour and that can leave my battery to about 80% to 70% when done.
Videogames: I use mainly the Morpheus(emu) usually about 20 to 30 mins and only seems to leave it close to 90%..
With random use I normally have to charge the battery every 2 or 3 days... I play with the phone quite a bit tho! Mostly text messaging (turning it on & off about 20 to 30 times daily).
With my 2 normal batteries? I think they need to be discarded soon lol!!!!!!! Wifi will deplete them(each) in about 4 or 5 mins tops!!! TCPMP about 10mins(screen on at its lowest with speaker) & 15 mins max(with headphones & screen at its lowest brightness)... Phone Calls? about 20mins tops(with the screen turned off)!!!!
So.... I strongly recommend the extended battery on Ebay for about $22(shipping included) so that you can enjoy the phone alot more!!!
I try not to keep the phone on the charger until the battery has depleted to about 20% when the warning comes on and fully charge it always!
Anyone else experiencing excessive battery drain on their HD2?
I am interested to know if this is just my phone or if it actually just chews through that much juice.
I have had windows mobile phones for several years so I know all the basic ways to keep battery drain down.
Stuff that I have generally found:
1. If I keep the screen turned on without it going blank I lose about 1% every 2 minutes.
2. If I am browsing that figure almost doubles.
3. My old Touch HD used about 5% battery overnight when in standby but this phone will go through about 25%.
4. The phone gets really hot when browsing (much hotter than my old Touch HD)
I have tried flashing ROM's and Radios but nothing seems to help.
I am not running any software on the phone that I wasn't running on my old HD1.
I have only had the phone for a week so I am not sure if this is normal but I would be very surprised if HTC released a phone that lasts for only a few hours on one battery.
+1
-1% every 3 minutes
-4% during the night (when i'am sleeping)
MAXIMUM : 45/48 HOURS

I wish I got 2 days
we really need extended battery ,hd1 battery was much more better.
Good mate but yes i agreee HTC has come up with a battery eating device this time around. My device on full charge just gives in around 8-10 hrs. This might be dat my EDGE is on and 7 mails accounts sending mails back and forth.
but truly i think that HTC better look into this very seriously cause more and more ppl are suffering in this battery drain..
Any of flashing roms and radio not helping either... did a complete hard reset but no step up
HTC come with longer battery battery for bigger devices soon......
The only solution i see now is get one of those extra battery worth mind bogling £52.87
I've had this problem ever since flashing to 1.66, I flashed the radio to 2.07.50.27 as this was said to solve the problem but it hasn't made any difference after a few days of use. My battery life used to be significantly better when I was on the original stock ROM, so much so I'm considering going back to it
I also know all the tricks as to clawing back the battery drain, my phone is idle on my desk at work most of the time and I don't use Wi-Fi, all the location stuff is turned off as are weather, stock and other updates plus my screen is set to 30% then off after 60 seconds. Despite all of that I lose 1% every 2-3 minutes
It seems to me that perhaps the radio is checking for reception pretty much constantly rather than say, 5-10 mins perhaps? This used to be a problem on my old Blackberry Storm but a few fimware updates solved it, eventually!
The only other thing I've noticed since the update is that once the battery drops below 50% or so, the drain seems to slow, I don't know if this is perhaps because the phone goes into some sort of semi-power saving mode?
Suggestions/hints welcome! I've had a semi-thorough look into this on the forums and tried most of the suggestions but still the problem remains. Will battery life improve after a few charges perhaps as this was a trait of my Storm's battery, the more you charged it the better the day to day battery life was (and no it wasn't because I had it plugged in all the time! Over time the general charge just seemed to improve when roaming).
Thanks!

You need to indicate what services you have running. Do you have any data services running eg: location services, push mail, weather? all of these have a bearing. In addition, network services can also drain a battery, especially if the signal is weak and the phone have to search for a transmitter, or 3g services.

That is a very interesting comment. Although since upgrading to radio 2.07.51.05_2 I have had very good battery life, I too have noticed a slowdown after 50%

Nothing is turned on, everything is set to manual.
As I stated I know all the basic stuff. I understand that all these things have a bearing on battery loss.
Everything I stated in the first post is for when I have nothing running. The phone is just sitting there running sense, thats all.
I have had my HD2 for a few days now. I am on Vodacom in South Africa.
I have not had a problem with battery life.
Yesterday i unplugged from the charger at 07:00. I spent about 1 and 1/2 hours of talk time on the phone, it was permanently connected to 3g doing weather updates etc. Sent and received a couple of sms's. Also played with a few tweaks and reboots.
When i got home at about 18:00 i had over 30% battery. I then surfed the web for over 2 hours to drain the battery.
try setting Network Selection to Manual

Same here with and without stock ROM.
yeah.. the phone is a battery sucker.... another cons of HD2....
This is very interesting to read because I do not have this problem. When I left my HTC HD2 on last night (I woke up at 4 in the morning to get something to drink and unplugged it) and then woke up at 8, it was at 98%. That means it went from 100% to 98% in 4 hours. Not to bad imo.
I am now at work and it is 15:34, and I am at 87%. I have made some calls, watched some videos, send a few text messages. Not much (I am at work so I got other things to do). So 08:00 (98%) - 15:34 (87%) - that's 7 and a half hours, with some calls, text messages and a video.
I am pretty sure when I get home at 18:30 the battery will still be above 75%. Then I connect to my wifi at home, refresh twitter, weather, browse the web a little bit, check e-mail etc. So that will drain my battery a little more.
But overall I have not had any problems with my battery life. I always make it trough a day, and never have a problem like 'damn my battery is almost done and I am not near a charger'.
Some info that might help:
I do not sync ANYTHING automatically. I still have some things to do with my Vodafone contract and do not have an unlimited plan yet. I only sync at home on my own wifi connection. For me this is not a problem, because I only need to refresh the weather each morning to see what the day is going to be like. Twitter I only do when I have the time. Stocks I do not use.
I have screen brightness set to automatic.
I am on 3G most of the time.
I am running the official 1.66 Dutch ROM.
I have some tweaks, games and programs installed.
I hope you all solve this issue, because it just can not be that my HD2 has a good battery life, and your HD2 not
Kind Regards
EDIT @ 17:00 still 87%.
I am in a 3G 2100 only network (I don't have 2G functionality).
ROM: Artemis 3.0
Radio: 2.06.50.23_3
Customization: Seiya 6.5.5
I don't leave any automatic updates on, except for my e-mail account every 2 hrs.
I never close my connection.
The drainage overnight is -3% (8hrs).
The battery lasts at least 12 hrs of intense usage.
Normally I have to recharge every second day (e.g. I charged last night, I answered a few calls, I did some IM and browsing and I still have 73% left).
For a phone with a 1 GHz processor, a 4.3" screen and a tiny 1250 mAh battery I find the drainage is rather decent.
Mind you, I ALWAYS do at least one full charging cycle to my battery after flashing a new ROM. I mean: full discharge, battery out 1 min, full charging in OFF mode, battery out 2 mins.

I have seen this process recommended a couple of times now. What is the theory behind it if you don't mind me asking?
maybe its also becouse some of us couldnt wait using the hd2 when they got it (like me) before it was fully charged for the first time
anyway my battery life has improved a little bit, i was at 74% this morning and did a lot of browsing, installing, tweaking and now its at 3%. it used to be much worse
I have battery consuming problem from time to time.I did everything:
installed new stock rom 1.66;
transfered all data which phone is using from card to phone memory(pictures,icons,sounds.etc...)
all updates are done manually;
Gprs connection is swiched off on the idle after one min;
One night it is loosing from 2 to 4%;
another from 30 to 40%
and it is eating memory from 10 to 15mb
I think that it is radio which is causing battery drainage so fast(to much communication wit a base stations,because when I am checking spb wireless monitor in the morning,there is no any data traffic.
I hope they can solve problem,because it is getting me mad and crazy
Try setting the screen brightness to 10-20% (on battery powered)
and dim backlight after 10 seconds (on batter powered).
It helps a lot, at least for me.

as far as i know, the battery has an integrated digital circuit (ic) which estimates the state-of-charge (soc). the procedure resets/calibrates the ic to obtain a more accurate estimation. since the radio rom is in charge with the power management (among other things), by changing it you decalibrate the "gauge".
i don't know if i've got the theory right but i tested this myself and it surely works.
I was pondering possible reasons for the battery life problem that many of us are well aware of. Some peoples batterys will last a good day or two and then theres people like me who charge my phone in the morning and when i get home in the afternoon just to keep it alive and this is compared with people using the same rom. So i thought maybe there could be something to do with what the battery level is when the phone is rooted or a new rom flashed, and this process may reduce the battery cycle to a specific point. E.g. if i 1st root and load my new rom on my phone at 50%, when booted it could show 100% but its actually 50% than it should be. i have not tested this but im just putting it forward as an idea. if anyone does have the time to unroot, charge to 100% and then reroot their phone + custom rom and test the battery life could they please post their results here. No harm in trying ...
EDIT:It seems we have found a solution or alteast a way to greatly improve battery life by putting my random idea and the information from maxisma togethere.. here are the following steps:
1. When the battery is low e.g. 10% boot into recovery mode and wipe->battery data
2. Reboot and then drain the battery or let it die (turn on mobile network add the 'sync now' widget and keep syncing with the music on loud - works pretty fast)
3. Leaving the phone dead put it on charge and let it charge fully till the led indicates green (may take longer than normal)
4. UNPLUG!! the charger then boot the phone up and your battery life should be much better
TIP!! Remeber when changing and flashing new roms to unplug the phone from charge after you boot!
Hope this works for you all PM me for results (i went from 5-10% loss an hour to what is now about 1-2% max )
Nice idea but almost certain your wrong
Edit: turns out that you shouldn't boot your phone while charging after all
I've think it's more likely to do with how I charge my phone. If I charge the phone on my PC then the battery lasts me a day. On Sunday night I charged it with a mains charger, and a day and a half later I still have 40% left. That's with constant WiFi, Talk, calls and text messages.
Sometimes I'll do the same things mentioned above and the battery will be about 20% by the time I'm going to bed.
I could be very wrong, I'm no battery expert!
There shouldn't be any difference between PC charging and mains charging. The mains charger would utilise a transformer to give the same oomph as a PC gives...if not it'd fry the battery whilst charging.
Funnily enough, mains AC - DC transforms are a little choppy, although at such a low current it should be entirely negligible, but your PC's power supply should give a cleaner power output than the mains. Are you sure it isn't just a placebo, I still like to think charging my PSP via the mains rather than USB will do it quicker and last longer, since its dedicated

I've heard this theory before. I can't even begin to fathom how this could be possible. I hereby dismiss it as 'rubbish'.
Seriously though, I think it's far more likely to be related to the apps/widgets people are using after flashing the rom. The only thing that differs drastically from build to build is the different apps that people install.
Might be worth those with very crap battery lives sending me an hours worth of logcat. I can do an hours worth of logcat for myself (I never have battery issues), and compare the results.
He's partly right.
Android has a bug that when it's plugged into a charger while booting up, it'll report a higher battery status than it actually is.
This is preventing the phone from charging the battery completely.
So, a recommendation for you: Always unplug your phone from the charger before powering it up.

Since my last post ive drained my battery out. Kept the phone off and charged it fully. It did take longer than normal which could be a good thing. Ive booted it up about 15 mins ago and il post later/tomorrow about how the battery performs now.
WOOO
I maybe jumping the gun a bit here but my phone says an up time of 1hour 27 mins. and normally its about an hour to about 5-10% of battery life and im sorry to say... im still on 100% WOO . I will still report how this lasts through to tomorrow, however i think theres enough evidence to suggest that the method stated earlier seems to fix what seemed to be a 'shortend battery cycle'. Anyone else with a short battery life i advise you to do the same asi have and please feedback to me with any results.. hope this has been helpful
EDIT: Its been two hours now and still 100% woooo
I got escited too bratfink when I had 100% battery for ages while it was in sleep, then I dl'd a few progs from market and whoosh my battery started disappearing faster than expected. Try downloading a few things and you'll see your battry disappearing quicktime.
minfree or ramzswap off could be causing the issue.
I remember before I put that tweak on my phone (when it first came out), my battery life was amazing.
After I put the values in for init.d as from the forum page below:
http://forum.xda-developers.com/showthread.php?t=622666&page=6
the battery life started disappearing like mad! and this was on a modaco rom!
I think now that all the new 2.1 roms are including this minfree tweak it is causing this battery issue to be carried over. All attempts to reduce battery drain are not having as much effect as they could because of this.
I would like to try one of these new roms without the tweak but I do not have the knowhow to stop it. i.e. put the original init.d (or equivalent) for the the roms in place.
You might argue that the memory clearing has nothing to do with the battey drain, but what i saw was that it did on a modaco rom. I don't know whether it is the switching of ramzswap or the minfree settings ( i have a feeling it is both.
Can a chef cook one of their roms without the tweak and keep the original settings?

I'm on the BeHero v1.3.2,m will that command put my phone memory settings back to what they would normally be without the taskkiller?
If so can I just remove that file with OI file explorer as atm my laptop usb aint working (can't connect to phone properly, can only charge)
If you use Bluetooth, GPS*, or plug/unplug usb, CPU lock at 528Mhz and battery drain. This happend in all eris/roms.
I can see with Battery Graph while I sleep the battery is full, but no reason (only unlock to check time, kill alarms, read mail,...) the battery drains constantly. (no tweeter, no facebook, no GPS, no BT,..),
This kernel sucks. It's very buggy but is what is

I am currently performing the third step...i really hope this works cuz I am getting really really horrible battery life right now...I get only about 8 hours with ocassional use...like listening to music, browsing, taking pictures, sms.
thanks for posting this thread.
Ill post the results tomorrow ( hopefully positive)
I noticed that using the overclock widget (even with the lower clock option when screen is off) also eats some battery, it definitely reduced my usage time on Android 1.5.
Could someone confirm?
I dont know what it is and why people have this bad battery drain.
I have the VillainRom 3.4 installed. Totally NO drain. I turned on Bluetooth and called several times. Battery drain is 8% in 12 hours .
I did not install any widgets. Pure standard custom ROM with newest radio.

exactly my view.
I'm using HeroDroid and i had really bad battery drain problem. I'm a sort of heavy user and with bluetooth & gps permantly on, my phone had drained out by lunch time. After doing some tests, i have found that my problem was related to GPS. If i boot my phone with GPS off and left it at off, i get the same battery level usage as my original cupcake 1.5 ROM. Perharps you guys can try it and post your results.

I found that to help as well. In the last 3h10m it only went down by 4%. That's definitely a lot better than what I was getting before and with the previous ROM. I am using the new Autokiller and Overclock widget if that helps any and booted up with my GPS off and followed the steps mentioned in the first post.
hmm if its the case that the phone is "capping" the maximum amount of charge the phone can have then it should take longer to charge also
my battery life i kinda okay, lasts 10-12 hours with intermediate use, using battey graph app it took me 70 mins to charge from 40% to 100%
ill let it drain out tonight and see how long it takes for a full charge
it would be good if we could compare results with people with and without battery problems
Hello all,
I've had my EVO for about 2 months so far. I've notice just like everybody that the battery life sucks to hades. I've rooted the phone since then.
1st problem) Maybe it's me or it's a problem no one addressed yet, The phone will start getting hot when it is in standby mode. When the back light goes out it gets hot. I've check to see if there were any wild or un-needed services running and there isn't, and its not like McDonald's Coffee hot but very very warm to the touch. And when it does that the battery life starts at 100% and ends at 20% within 40 minutes.
2nd problem) I've installed two programs in which I've deleted since the time it happen. A Super User Permission app, the one that's gray and has the jolly roger look to it. The next one is Juice Defender. I notice the problem after I installed them that the phone will start restarting itself like every 3 or 5 minutes. I'll be in the middle of a phone call and it would go blank and restart. The only time I notice it doesn't do it is when I connect it to the computer while I have debug on and when I do a hard restart in which I pulled the battery out. The battery trick only lasts for about half a day. I installed those apps 4 days ago, both at the same time.
My phone info is:
Software #
1.32.651.1
Firmware version:
2.1-update1
please help!!!! it's driving me up the wall.
I'm no expert but it sounds like a rogue app to me. If my phone were doing that i would wipe it and start from scratch.
Just my thoughts.......

Try updating to one of the rooted 2.2 Froyo ROMs. Be sure to do a full wipe (data, cahe, dalvik-cache) before installing a new ROM, unless otherwise instructed. You're running an old software version of Eclair (current Froyo is 3.26.651.6). I've received considerably better battery life since the update to Froyo, especially with a custom ROM and custom kernel. I personally run both SetCPU and Juice Defender with no problems or any overheating issues.
Mostly it sounds like you have something locking your CPU usage at 100% which would explain the heat and battery drain. I suspect you may be having software conflicts using the old OS version. Do a Nandroid backup before flashing a different ROM so that you can rollback to your exact setup you currently have if you do not like the results of the updated ROMs.
And by all means, DO NOT flash an unrooted stock Froyo ROM (or take any OTA update). There still is no method to root that.
Yeah I have been debating the whole wipe the phone and start with the 2.2 OTA and wait till they root that. This is driving me mad, cause it's seems it knows when I need it the most. When I'm at the house it last and stay up like a champ, when I leave it starts acting up.
Which leaves me with the question how do you save the apps on your phone?

Appbrain is a good way to manage apps. Any paid apps should still show up in your downloads section of the market after a hare reset. I have no battery problems with the ota 2.2 patiently waiting root. Don't know if I'll root when they do figure it out because its pretty stable with decent battery life for me.

So today is Day Two since I changed the ROM. I have notice alot has changed, some things are new, and some things are working that never work before. It's like having a new phone all over again. LOL
I also use the instructions in the thread about battery life
Edit: I can't link it due to new user access. But its in the General fourm.
15 hours and I haven't plugged it up yet to recharge it yet I still have 60% left on the battery. I made 8 phones calls that lasted 2 mins and more, plus ran the music app and more.
I want to thank you guys for your help
Do you getting more then24 hours on a stock battery?
Do you keep 3g on and always connected checked?
You have to be a real light user
No sir.... by no means I'm I a light user. As I stated I use my phone pretty heavy and that was only day two that I done that.
Yes....I now get more then 24 hours out of the stock battery.
At 7am I unplug and jet out to work. I use my phone as a MP3 player for the car. 30 minute drive to and from. When at work I play games and make random phone calls for 9 hours of the day. SN: I'm doing my job also When I leave work I go to my gf's house which has no signal out there. I use to have to put it on Airplane Mode to save the battery. Now I just leave as is without changing it.
Total time using the phone in 24 hours: 14 hours
Times I charged my phone in 24 hours: 0
Battery Percent in 24 hours after 14 hours of use: 45%
Longest hours since unplugged: 2d 2h 4m 10s with a 50% life left.
Yes I keep my 3G on. I turn my GPS off and Background Data, Set the weather app or widget to update every 6 hours (Why would you need to know the weather every hour on the hour, Just press update when you open the weather app) along with other things I don't need running while I'm at work or even not using them.
This is with the OMJ Froyo 2.2 Rom update. The phone is still running smooth and as it should (in my opinion)
One minor but major problem to some I wish they would fix.
Multi-touch though out the whole phone. The Droid X, Incredible, and Nexus 1 has it.
Why can't we have it. I would be so happy if we can get that.
I have found a way to solve the problem with the battery in a few simple steps without erasing any battery stats or doing anything.
Firstly, install a Start-Up manager to control the apps wich are started after every boot. Leave only the important ones!
And now you have to recalibrate your battery, so
here is what you do:
1. Charge your phone to a 100% (that will take you about 3:00 hours)
2. Discharge the battery until the phone turns of by itself
3. Try turning the phone on until the battery dies completely and the phone doesn't start.
4.Take the battery of and then put it on.
5.Try to turn the phone on until the battery dies completely.
6.Now charge it up to 100% ( minimum 3:00 hours no matter that the phone says it's charged)
7.Ready! Now enjoy your amazing battery life!
Note: I recommend you to charge the phone for minimum 2:30 hours no matter if it says it's charged. Now, i charge mine for 3:00 hours wich is enough.
Here is one Start-Up manager. I use it.
how many days with wifi, gps and so on... ?
Well, before that I was unable to last for half a day. I had the same problem with all of SwiftDroid versions so I followed these steps and my battery life has increased dramatically up to 3-4 days !!!!!!
I use 2 hours wi-fi, 1 hours listening to music trough headphones and my brightenes is set to 40%.
Hope i helped you!
I see this post on all threads....;-)
Sent from my GT540 using XDA App
Thats isnt a battery problem. After you take a call some google services are using the CPU with 100%. After ich kill the google services tasks the cpu goes down to 20%
NO. Before that procedure I restart my phone and don't talk with it and the battery drained ... And after that procedure I talk and there is no battery draining so it's not because that.
thanks gonna try it now
mine goes on for about 2 days, with SwiftDroid Milestone1 Version 2.0

Click to expand...
Click to collapse
if u rename system/bin/akmd2 (akmd2_backup) and reboot,
you get another 1-2 days, but lost compass and
accelerometer, this process permanently takes 1-5% of cpu, but there is no other solution
i try what i found on internet
adb shell
echo 250 /system/data
but not sure if something change, i also found some open alternative,

..it works very well for me after doing this.... i might even say it lasts a bit longer then on stock 2.1 with cpu tuner and settings ofc.....swiftdroid v2.0 M2...
There is a good application on the Market. BatteryCalibration
You need to have root. Extended my battery life for 1-2 days!
helps a little bit... but nothing like 2.1 stock
I'm on 2.1
Nothing helped. It is possible that battery just reduce its capacity? I dont want to install another android just to see how battery is there...
nah im fine atm. i always charge at night and my battery lasts till about 10 oclock, then it gets to 10%.
I've installed joes 2.3.2 without any battery-problems.
i'm running setcpu with 852max. -> did you set "on demand"? when setting to performance your phone will run out of battery within a few hours.
my battery life is around 2-3 days with AOSP 2.3.2 @ 852mhz max.
before with 2.1 @ quarxblackkernel @ 800mhz max. around 2 days
