Hello, I`m new to this forum and wanted to ask if anyone knows why my HTC Legend drains battery so fast. My phone is rooted with Fuse ROM and unlocked bootloader but it was draining battery on stock ROM too. Even with the screen of it drains ( in 8 hours with screen off it drains almost 10%). I have 3G connection on all the time and when I`m at home i don`t have full signal in the house so it may be a network problem that affects the battery?
a weak network signal may be one reason for the battery drain (since your phone has to use more power to send data).
however when there's always synchronisation & exchange of background data going on in the background, i think 10% battery down in 8 hours isn't way out of the ordinary.
maybe you'll get some clue, what components are causing the drain when you go to settings > about phone > battery info...
Best solution to stop battery drain is turn every thing off if you're not using it eg GPS, wifi, Bluetooth, mobile data, auto sync, if you have them on they will chew up power.
On a stock legend, HTC would seam to have the CPU speeds set at 480 low and 600 for high, if you root and set your lower value to lower than 480 that will also help in cyanogen lowest value is 245.76, this seams to be ok, on other roms they can go as low as 19, this is not so good as phone can sometimes freeze. I never go below 122.

My HTC legend battery life is 2 days. But I enable internet access only when I want, same for gps
Have you tried to calibrate your battery after installing custom ROM? Try the free battery calibration app from the market.
I'm using "[ROM] B 0.8.4 based on stock HTC FroYo (04/13/2011)".
Using the stock speeds the battery drain is quite fast, I get a day at best. I'm running 245 - 804 and this makes the battery last days. I'll try down to 122 to get a tiny bit longer battery life

it is a common problem... as long as your phone signal is not dropping to completely zero that it goes for finding alternative networks its fine.. but if it is dropping blank .. try using airplane mode (ya no other option )
or else as a quick thing try below options
- try installing infolifes battery defender (tweak their ignore list if required). along with their advanced task killer (jst set for auto kill when screen off and not interval kill
- get a cpu governor (I was using cyanogenmod inbuilt one) and set in conservative a low-400mhz and high-600mhz
-turn off auto brightness if u've it on and use it in low as required
hope these should squeeze some more extra standby time..
I went back to a stock rom after putting up with the battery issues.
a friend told me that there's a .bat file that helps with the battery issue, but I haven't been able to find it anywhere.
I also had freezing problems when I tried to adjust CPU settings, so my best option was to bake a rom through modaco without all the bloat crap.
Now it works a treat.. hope this helps
Bat files are for windows computers, not used on android....
However your friend might be talking about the "battery.stats" file deleting it is supposed to help "calibrate" your battery, I personally have not seen any benefit to battery life doing this. Once your phone goes flat (turns off) and you then fully charge it it seams to set the calibration automatically. The only way I can see it actually helping if your a phone user that never let's the phone go flat enough to turn its self off.

IMO, battery life isn't bad on the HTC Legend if we compare it to High End phones. But there are ways to save it.
Ceebs typing the whole thing so I might as well link it to you from a similar topic: http://forum.xda-developers.com/showthread.php?t=1586022
Cheers ranger.
I asked him about it, and it was a .bat file that is used through the adb and he didn't say where he got his information.
Removing the battery stats file can be done with an app from the play store, and that wasn't anywhere near as effective as the move from cyanogen 7 back to the baked stock HTC rom.

Hi Everyone,
I am disappointed with the battery of Optimus One.
My Battery in Standby (GPS/Wi-fi/3g/Sync/Screen, ALL OFF and without USE ), does not last even 20 hours.
I have an application that shows what application is consuming more battery power and the "phone in standby mode" takes up 95%!
What are your experiences with this battery?
Mine has problems?
Thx
I bought it one week ago and the battery last one day with no problem (and it's not at its full "potential" since is new). When did you buy the phone?
I bought it 2 weeks ago
Using a custom rom you won't be disappointed with your battery no more...
I have openOptimus Rom with Franco kernel 15. I am at 85% battery after 14 hours. The phone has been pretty much idle.
Only 2G networks
Data disabled
Wi-fi on
Auto-sync on
Overclocked 480/729 interactive (interactive may not be optimal)
I'm using franco kernel v15.1 with devoid.franco, i'll try do update do devoid.froyo.final today.

Hi, what is data disabled? and how to put only 2g networks?
20 hours on idling? Send it back for repair/replace. Mine will last days if left idling (about 1% every two hours)
When I travel I turn all data connections off (Bluetooth, wifi, gps, data) and it lasts about 3days

Here are some potential things to turn off that might make the battery last longer. They are all in the settings app. I do not do all these since I find that some things might make the battery last longer but reduce the usefulness of the phone.
Setting/Display/Brightness
Setting/wireless & networks/wi-fi off
Setting/wireless & networks/bluetooth off*
Setting/wireless & networks/mobile networks/use only 2G networks*
Setting/wireless & networks/mobile networks/data enabled off* (I have this turned off all the time as I do not have a data plan.)
The items * I have off unless I am actively using them. I also overclock my Optimus. I think that this probably gives me a longer battery life, since it is running at 480 when I am not using it. I suppose if I was desperate, I would undercloack the phone (min 480 and max 480).
What version of Android are you running? 2.2 or 2.2.1/2.2.2?
When you click on Cell Standby, how much Time Without Signal does it show?
follow these steps and i think ull have what you want..
go to battery use and click on cell standby : then see time without signal. how much does it show ? if its above even one percent (unless uve mannually put ur device in airplane mode) i know the problem.
go to settings >wireless & network settings > mobile network > mark 2G only (if u are not using 3G) cause the cell might spen loads of battery searching for 3G.. then go to network operators and search for (mannually) and select ur own network provider.. like mine is airtel.. then let your battery run down totally.. completly to zero. then recharge your phone to full without any break.. this is called recaliberation. then see how much your battery lasts..
remember to turn off bletooth, wifi, internet, all ! while the phone is idle and you wont be using it for sometime. or, if you wont be doing or getting any calls or sms, consider switching to airplane mode..
you might be getting less battery if ur in a area with weak signal strength.. this makes the phone go wilder to search for signal. in these conditions, switch to airplane mode if you can . thatll save a lot of battery. and also during night if you want to.
dont hesitate to click the thanx if i helped !
EDIT: and ya every thing that the person after me 'Y.u.v.i' said.. though those are normal things and brightness level is most important..
and about francos kernel, ive had many f/c s with mik's cm7 beta 6.2.5 ..i prefer its own kernel , though dunno for other roms.. u might wanna try it.. ill try myself too..
yes ..few step here u can try
1.reduce ur brightness level to minimum ...
2. use 2g signal only.
3. turn off all extra connection like wi-fi , Bluetooth, auto sync , data.
4. use advance task killer and set it to auto kill app aftr every 30 mints.
5.automatic screen time to 30 sec.
6.if u r using custom ROM use Franco 15.1 kernal . and wipe battery after charging it up-to 100%
use thanks if u like my post ...
I did all the tips posted here. Let us now see what happens

I'm using 2.2
7% without signal.
Sorry for the dumb question (about 2.2 or 2.2.x) - I didn't read the first page carefully enough.
Try this: reboot, then enable airplane mode, lock your screen and leave it like that for about a minute, unlock screen, disable airplane mode.
Are you still seeing Time Without Signal? (of course, after a few hours, not straight away)
EDIT:
DON'T do any of the following:
- reduce brightness to 1%... come on, be serious! you really like squinting at the screen? screen brightness doesn't affect battery life that much anyway...
- don't use task killers! it doesn't matter if you have little RAM - it's there to be used. I will not go into details about this (there's whole threads about it), but trust me!
You could also try monitoring your apps with https://market.android.com/details?id=com.zomut.watchdoglite&feature=search_result and see if any of them start behaving wildly and keep your CPU awake.
Another thing would be to try Nessy Hypnos2... I had great battery life when using that ROM! If you're still experiencing the same battery drain with a fresh install of Hypnos, then I'm sorry to tell you but you'll probably have to send your phone for repairs.
I ended up recharging the phone two hours ago and it is at 91%.
Was 9% in 2 Hours - 4,5% per Hour. Very Bad...
...with nothing in use.
Only 2g networks
wi-fi/dates/sync/bluetooth ( ALL OFF )
Screen OFF (black, with -0% of brigth, because he is OFF)
I install Battery Monitor Widget that estimates my uses of battery in:
18h52m of Discharge (100->0%)
and 5h of charg in USB and 3h of charge inc AC.
I'm installing watchdog now, to see if have an App draining battery.
EDIT:
But I do not think that's because I have an application that shows the the CPU clock in%.
480MHz = 80%
729Mh = 20% or less
and another that shows the applications that consume battery
and Cell Standby = 90%

I got the same. My phone is also on the same settings, same rom, same kernel. Battery life was awesome some days ago, but now I experience average battery drain, I think I need to callibrate my phone as well. :/ I will do it probably after flashing void.final.
Are there any good ways to extend battery life besides the obvious stuff (no WiFi, GPS, screen brightness, etc.)? I just converted from my iPhone 4 to a Nexus S and battery life is pretty miserable - I can make it through a day but I have to plug in as soon as I get home. If I could stretch that 12 hours to 18 or so it'd be perfect. My iPhone could do 24-36 no problem, so I feel like 18 should be reasonable.
You can try different kernels for your firmware. The custom ones (good ones) normally consume less battery.
You can try to calibrate your battery, as well.
That is if you're rooted. If you're not there's not that much you can do. Install Current Widget from the market and let it be in standby for around 1 hour with WiFi and that stuff off, and check how many mA it's draining.
Other than that, turn auto sync off, and don't let everything send out push notifications (news readers, Facebook etc.) and if you're using a weather widget check that it's not updating every 30 mins or something.
BazookaAce, but having a smatphone like this without being rooted it's a waste of gadget...IMO.
Yeah, I'm rooted and running brainmaster's MIUI ROM. I do have syncing turned on for everything, I'll try messing with that since I certainly don't need FB or Twitter updates every 30 seconds.
just dont use any of battery saver tools. it doesnt work. wipe battery stat if ur phone rooted.
I have a similar problem. I am running an XT860 and am barely getting 12 hours and that's with an extended battery! I have read that keeping the software on your phone up to date usually improves the battery life.
What kind of droid do you have?
Root your phone, install cyanogen or miui.
Download setcpu app.
In setcpu, set it so your phone uses 500-600 mhz of processor speed when the screen is off.
That alone should help your battery life by at least 25%.
Not so sure setCPU is the end all solution here. I have this as well and I have mine actually down to 245mhz when in screen off mode, yet my battery life still is horrible. I have screen brightness pretty low and only gmail is setup to autosync, and checking the stats gmail does not use much of the battery.
I think it also has a lot to do with how good of a signal you get in your area. If your phone is constantly cycling through to get a signal that will eat up your battery as well and is pretty much out of your control.
Dropping the speed with the battery life sucks hd2 setcpu that does not taste at all
I have been messing around with system tuner app for a while now and I really like the program.
I would like to hear from people who have used this app and their results with various tweaks that this app provides.
in the boot settings menu:
1. forcing both CPU's online: this should technically give you a better battery life, since it puts less strain on on cpu at a time, has anyone had a good exprience using this?
2. Boost app loading: anyone had any significant improvement with this?
My own settings:
I usually clock my phone at 1.5 (on demand governor) even though faux's kernel allows 1.7 max. I put max clock for screen off at 384 and conservative governor.
I have Undervolted before but do not see a very significant battery difference so I just left it alone.
I tried out the autokill option of system tuner, I only tried to kill the ghost apps, to refrain from the cpu from having to keep restarting the phone, but this also seems to kill battery life...In my experience any type of task killer however detailed will reduce battery and does not increase performance, unless you're running a poorly written app that just needs to be killed.
I use three other programs to monitor my phone
1. system pannel: very good at finding rogue apps that kill cpu...I highly recommend the pro version, you can get a history of what has used cpu up to a week.
2. Onavo and My data manger which basically monitor my wifi and mobile traffic, Onavo only monitors mobile network traffic and lets you restrict apps to only wifi. however it does not measure wifi use of data. My data manager monitor both wifi and network usage but does not give you any options to do anything with the apps, it basically tells you what program is using data while on wifi and mobile.
If anyone has found a good balance between performance and battery saving, please do share.
Thank you.
I read some other guy also mentioned the all cpus on thing. im not sure but isnt it the same as making both processors work at the same time which leads to phone overheating? I will give it a try though. from what you noticed, do you like it more with both cpu on or is better the way it was?

will see then. hey seansk do you notice some kind of hesitation when trying to unlock the phone? when u press the unlock button at the top. I think that boost app loading thing causes this cuz when have it enabled the unlock button you have to press it twice to work, while when disabling that boost app loading thing all works fine...

I have widget locker and havn't had that problem...I just flashed faux's latest kernel and am in the process of re calibrating my battery, it seemed to jump from 100 to 90 in about 10 minutes!!!!!! now I noticed that happening...but I havn't had time to fully replicate it...i need more time..I believe it might have something to do with fauxes kernel, he mentioned that when screen goes off he it puts the phone into a low power consumption mode, but also has something that when you turn it on, is quick to turn on!!! we'll have to wait and see.
If you've been following this thread, just wanted make a quick update...I want to give you my results with system tuner tweaking. Forcing both cores online is a bad idea. It will literally kill your battery in a matter of a couple of hours. ICS will hopefully be different and utilize the cores how they should be, saving some battery and giving the amaze longer battery life!
On the other hand reducing reducing clock frequency on screen off will help in battery life (obviously).

yes still stock rooted, I put the governor on conservative and put the frequency to 384 or around there, while screen is off.
What helps most I found out is turning off all the radios like wifi and network data, (basically putting phone on airplane mode). Instead of dropping down 15 percent in 6 hours it drops like 3 when I turn airplane on. But like I've said before it's unrealistic I'm always recieving google talk, google voice, facebook updates and I have to have both of these on which unfortunately eats a lot of battery.
I keep switching back and forth between faux's kernel and stock and I'm actually finding stock gives me better battery life for some reason. Even though I set the clock speeds on both at 1.5 ghz.

Major battery drain is the screen, when on eats up all the juice, dimming helps a bit
charge source: usb vs AC charge
usb charging takes quite a while, AC charge quicker (~ an hour)
Also, from my observation, usb charged battery runs out quicker than AC charge
Data Connection, Juice defender helps a lot

well the problem is its not my screen. It's when the phone is idle, I usually lose about 15 to 20 percent over night. if I turn off the radios it drops down to about 3 to 4 percent overnight....like I said before I can't turn off the radios...I constantly use google voice, google talk, facebook. And they require both a cell connection and a data connection. I hate to pay for more apps...I've already paid for a bunch of apps to control and see my phone's usage of cpu and battery...is the app really worth it? wish they had a lite version

I have juicedefender ultimate, used it for a while actually...the only good use of it is turns off radios all other things when screen is off..all other things are negligible to battery life...I currently don't use it anymore. I tried multiple things/tweaks with it for about two weeks,...NO point lol...I want to be able to get my google talk message and my google voice texts, it annoyed the hell out of me when someone had sent something like 2 hours before and I would just get it when I woke my phone!!! I tried all kinds of things...but the only thing that actually worked was turning off radios during screen off which I don't want...I can't win lol....I can't have my cake and eat it too!!

while you sleep, you won't be checking for emails will you? but you expect to wake and see emails received.... that is where it comes in handy. with apps like tasker, you can automate some of this activities. tasker + syncer should be a good combo for you.

For what it is worth I am running BulletProof 2.3.1 and last night I took phone off charger at 10:00 PM, alarm goes off at 3:30 snoozing every 15 min until 4:15...Battery was at 100% still. It is now 7:00 AM and battery is at 96%.
This was after flashing back to BP around 8:00 PM.
I've noticed the same type of activity when in Airplane mode. Extremely low power consumption - fantastic.
Is it possible maybe to undervolt the Wifi/BT/Mobile radios? Would that make any difference or am I off base here?

You had something setup wrong then I think.. you can change how often in syncs while the screen is off, the default setting is for it to turn on data for 1 minute every 15 minutes. Most people don't need to know things so bad that they can't work with a 14 minute delay(at worst), and of couse the internet is on while screen is on, when you're actually using it.
I thought I would need to use juice defender, but since I switched to bulletproof, my usage last me an entire day. From 8am till 1am, usually with some to spare. The only tweak I made to cpu was to enable 192mhz, it isn't like there is a performance drop, but it did make a notable difference in battery life.
If I wanted to I could use juice defender to get more than one day out of it, and I keep a spare battery on me in case I really need to use the phone.. but haven't really needed it.

I always suggest that users turn on extended standby mode but some people want their whatsapp or email to come through instantly all the time which I can understand but it's a real life saver for me, I personally don't have a massive issue with my battery, lasts a whole day, sometimes less if I use the phone heavily.

The autobrightness is on, and nfc and bluetooth are always off (since i don't use em)...I need my e-mails, and Whatsapp is not even installed on my phone..turning 3g off or enabling the extended standby mode is like ... hmmm, i carry a 4 inch useless device around ... (

Your emails would come as soon as you turned on your device anyway could you screenshot your battery usage please?
i don't know how to take screenshots
i understand that the e-mails arrive as soon as i turn the phone on, but this is not ok...it will become a habit to look at the phone ....
Very easy to do, hold volume down and the power button

I think there is also a problem with reading the actual battery level (hopefully not hardware). The other day mine dropped from 15% to 0% in 10 seconds. This has happened a few times before when the battery gets around that level.

Try disconnecting your battery then, hold power button and volume up till you feel 3 buzzes

i have to root the device and to be honest, i am sick of it ...
attached screenshots...bare in mind that 3 hours the phone was on 2G and the display was as dark as possible (unable to see anything in the day light)
You could use clockwork recovery to erase the battery stats as well. I don't think you need root for it.
You charge to 100%, reboot into recovery erase battery stats, unplug and boot normal. After that you let it drain on its own until dead.
I've read that sometimes it worked after the second calibration or something but i believe it might be user error.
I erase the stats every time I flash a new rom. ...
I am now on 2.3.7. ... Maybe is better

Battery stats doesn't do anything: http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/
That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.

I would advise you to update your phone to the latest firmware, it has better battery management... If you are rooted, you can try custom kernel like ThP or Sliding_XP and custom Rom based on stock... I used to get only 10-12 hours of battery life in 2.3.7 before rooting.. The steps I took to improve battery life are:
1) Root the phone, add init.d and build.prop tweaks or install a Rom that has tweaks like Brain_ICS or XPT's Vision Roms.
2) Use any custom kernel based on stock that are tweaked to give better performance and battery life, along with above Roms
3) Switch off WiFi, Bluetooth, NFC when not in use. Or better, use NFC tags to switch settings (like WiFi on only at home, Bluetooth on only in car)
4) Keep the brightness to the minimum setting when indoors and keep it in auto brightness when outdoors.
5) I live in an area which has better 2g coverage. In network settings, if you set the network mode to select only gsm, battery life vastly improves as there is no searching and switching for a 3g connection. Also I find that staying in 2g gives better network clarity. I shift to 3g when I require high speed browsing only.
6) I usually keep data connected with auto sync on and extended standby mode on. If you switch off extended standby off, you can last through the day but only if you reduce the amount of apps syncing and the polling time of each app. In my case, I have switched off syncing for Twitter, facebook, Google+ etc and sync only for Google contacts, calender and Gmail.
7) I also have automated the phone to switch to airplane mode from midnight to early morning.
By the time I get home from work, I have at least 40% battery remaining. On the whole, I get 22hours on average and I have got 1day 12 hours maximum from my Xperia P. And happy with my choice.

Forgot two things:
I keep all location services switched off and turn it on only when required. This prevents the Map app from unnecessarily polling for location and helps save battery.
And sorry for such a long post. There won't be a tldr.

Just had this weird experience, battery was on 1 percent then I rebooted my phone using power button and volume up, then my battery shot up to 28 percent

that was android normal problem....thats why developer making phone by using high capacity battery (motorola razr maxx) . By using 3000mAh battery also just give certain phone for 2 days (using galaxy note 2). Android jelly bean suck battery juice faster because of its f***** project butter (uses cpu and gpu at the same time). Now phone developer starts frustrated on android...hehe (from my speculation)
Android problem how?
Almost all smartphones last about 1 day. Don't blame the Operating System it's the same battery life in all smartphones. Blame the battery technology.

one day means 24 hours...24 hours means more than i need .... i only get 10hrs if i don't touch the device...used, i get like 5 hrs .... anyways, thanks for your feedback...
PS: Xperia P, Red, for sale - 2 months old
Has anyone noticed significant battery drain whilst the screen is off, my phone loses around 1-3 % every hour even when there are no programs running. I have monitored the running apps and uninstalled many that were running in the background. Does this mean that the 5th core is not activating or am I doing something wrong, google now, wifi, bluetooth, 3g, etc are all turned off, If anyone experiences similar issues or knows a solution please post, other than that the battery life on this device is actually pretty good despite all the people stating how horrible and unsatisfactory it may be.
I believe someone mentioned that the WiFi is the cause of the drain while the phone is on, is your WiFi on while it's sleeping?

Google Now may cause battery drain while on standby, I think. You might want to install Better Battery Stats so you'll know what's eating up your battery while the phone is in sleep mode.
My WiFi, Bluetooth and 3g are all turned off and Google now has been disabled, don't know what is causing the drain but the people over at the original one X forum are sating that standby drain is higher as of the jb update which I find odd seeing that the battery life is better screen on.
Turn off auto sync & just enable it when you need to, or use an app that will enable it for you after a certain time period.

Nah I can go a day and half on stand by with little use. I have 30+ apps installed and mods to firmware plus nik3r's custom elite kernel.
I'd say its one of your obscure apps you still have I stalled. Do a factory reset on your phone and install each app one at a time each hr monitoring the drain till you find the culprit.
Install nik3r's kernel.

1) go to Facebook app, disable chat, disable location... disable auto updates/notifications too if you can. This crap (especially the latest version) can take 20% of your battery life easily.
2) go to Google Maps settings, disable all the tracking/reporting options out there (up to 15% battery life without ever even starting the map app)
3) install EliteKernel and use power saving if you need that extra standby juice (it actually saves power in my flavor compared to the stock version)
There - fixed.
Wifi is not the issue, I get better life on 100% wifi than on data connection. It's the apps that actually use tha data.
Thanks guys much better now!
turn off this, do not use that.....
if is this the solution what is this? a phone or what?
only hope a room that end with this battery drain, is not normal that my wife S3, the same battery (2100mA) like hox+ has more hours, and not only 1 or 2, 6 hours more battery life, both without use.... in the same place, we did it as a test and..... that´s the Q, why? we have the same apps installed, and we have the same on, wifi, data, gps, blutooth..... the same conditions
