HTC EVO 4G :: Short Battery Life With Cyanogenmod RC1?
Aug 4, 2010
I've had it for about a week now, and hoped it would get better, but it's just been atrocious. Much much worse than my stock rom ever was. I'm out of ideas. Does anybody know the latest radio version that CM will work with? They say "install the latest radios" but I have no clue where/what radios those are. Hopefully that will be something to help me.

Well lately my battery life has been horrid. If I am lucky I get 7-8 hours. That's with little to no internet use and just texting. Like now I'm at 70% and my phones been unplugged for 1 hour and all I have done is text a little and browse Facebook via the app for a little. I'm using BB .4 with the stock kernel. I was gettin better battery life than this before.

I got the fantastic Desire friday and I'm really enjoying it so far coming from iPhone and Hero.
Unfortunately I've run into a little issue: Up time and awake time (in Settings>About phone>Battery) are almost the same, meaning that the CPU never correctly throttles down when the phone is asleep. This is causing battery life to be rather short - On average I get 10-15 hours out of the phone with moderate settings.
By going to the battery info console (type *#*#4636#*#* in dialer) I managed to figure out that the calendar in some way is running and preventing the phone from sleeping (Partial wake in top dropdown). I did a factory reset and it hasn't seemed to help. There are 2 calendar related apps running: Obexservice and connectivityservice.

This is the first time I've rooted a phone, and i picked the Kaos Froyo V38 as the rom, but I've noticed since i did all of this my battery has been far far worse than what it was un-rooted. Today, for example i had my phone off the charger and on vibrate (with gps, mobile network off) and i was down to under 15% in under 5 hours. This is so much worse. Is it because i'm now running 2.2? What can i do to help this besides wiping the battery data (in the recovery menu)? I'm not really good with all of this yet, so some suggestions would be wonderful.

Ive been stalking the forums for a few weeks, reading up on all the issues and things associated with this phone and i can say ive experienced most of them (excluding rooting issues, i havent rooted).
*(of course) gps issues
*phone spontaneously shuts off and battery has to be removed before it will turn back on
*randomly awakes itself from sleep just to display the lock screen
*painfully short battery life
*no signal for a long time, have to restart phone several times before it returns.
These have all plagued me horribly the past month or so. then today it decided it wanted to....::gasp:: behave?
My battery still had half its life left when i got home tonight and its usually dead or yelping for a charge by that time (activity/usage the same today too). pages loaded quickly today and i had a signal all day.

We have 2 new Tracfone ZTE Valets. Android 4.1.1 Mine gets 3 days of idle battery life while my wife's gets less than one day.
Charge both, unplug and leave overnight. Mine has 96% charge in morning, hers 65%.
The battery section shows Phone Idle and Cell Standby using about 33% battery each on hers. On her phone the WIFI is listed as using about 33% as well, while mine is 5-6%.
For some reason "The Weather Channel" on mine is listed as using about 50% battery, but charge lasts days while idle. (I assume the % means it's share of the power being used, not battery capacity)
The Tracfone "My Service" app/widget on hers was stuck 'pending reply' and using relatively large amount of data (17meg) while mine used perhaps a few k data. I assume it was repeatedly calling home. Uninstall/re-install and now it gets answer, uses little data (I include this just for recent related history)
Both phones are set to "Keep wifi on while asleep NEVER". From reading this should increase data usage on cell and perhaps even increase battery drain - but it doesn't drain my phone sitting right next to hers. 3-4 bars on cell service.
I read that "Location Services" could be turning the wifi on trying to determine location. It's true all three of the location options ARE checked, but again they are also checked on mine. GPS is ON on both as well. Bluetooth OFF, screen dim.

It is now 12:15 am est. My phone ate it's first battery for breakfast and lunch and died at 2:15. Left the house at 930 for school, sat in class and surfed the internet for a bit, made a few phone calls to meet up with a friend at the gym. Once at the gym I used Men's health mobile workout app(recommend) at which point my 1st battery died, Pop in my fully charged 2nd battery cruising through the day few phone calls nothing over 4 minutes, sat in class browsed some more and played wixel and what the doodle....went out after calss for a drink.
Finally my droid had ingested its 2nd battery timing out at 11. I am rooted running at 1200mhz with profiles set...Also having lots of problems with swype force closing....anyone experiencing the same problem? also I would like to poll the amount of droid owners having a 2nd battery.

I used to be on a custom ROM called Cyanogenmod and really liked their circle battery icon in the status bar. I'm on a different ROM now that has no features and uses the stock android icon and I'm wondering if it's possible to get a white version of the cyanogenmod icon without having to change ROMs. I'm on an unlocked and rooted verizon galaxy nexus on 4.4.

The internal meter says it is due for charge long before its out of juice. Battery Left widget will give accurate voltage levels, but it too is fooled, even after proper calibration.

Does anyone else find that their battery does best at like 60%-70% charged and when it gets below 40 it moves a lot quicker? Also I've done 3 full drain and full recharges so far and my battery has improved sloightly each time, do you reccomend I do it again or is that just bad for the battery?

Background info:
- I'm running the "Battery Left" widget and I have it displaying "estimated percentage left", "system percentage", and "estimated time left until dead".
- I listen to A LOT of Slacker Radio.
My issues:
- I was previously getting about 19+ hours out of a fully charged battery. 2-3 days ago I started having issues with the widget (I think it may have started when I installed an update to the widget) so I recalibrated it to no avail. Then I uninstalled it and reinstalled it. Within a few hours it claimed that it was getting accurate readings (when I first installed the widget weeks ago, it took days to get accurate) and now says that I should be getting 9 hours out of a fully charged battery. I know that can't be right so I'll see how the widget adjusts itself over the next few days, but, any thoughts? (I know a lot of you guys use the same widget and know how it works...)
- Also, In the first two hours of my phone being unplugged this morning, it went from 100% to 70%. I did run Slacker for about an hour and a half of that time, but could it really drain the battery that much that quickly? And I noticed that when I close Slacker, if I go into phone settings, applications, running services - there's still a Slacker update thing running in there. Could that be draining the battery too, even if it's only checking for updates?
- I really don't run a lot of stuff on this phone. I keep wifi and gps turned off. I use bluetooth only a few hours each night. Minimal web browsing. Although, my POP email gets checked every 5 mins (but I just changed it to every 10) and I do use gchat and text a decent amount, but I'd say overall, it's "light" use (except for Slacker which could be a huge drain, right?)

My battery life was bad, but it was OK, but in the past few days my battery life is 10% per 30minutes(Just over 5 hours on a charge).I used to get 8-10 hours on a charge.I noticed last week that while it was charging the status of the battery was "Overheat".I think I somehow cooked the battery?I use TaskKiller and kill 95% of apps automatically, I have bluetooth,wireless,GPS disabled and the screen dimmed.I have not changed or installed any new apps.I have not changed the way I use the phone at all.My battery was dead, 0%, and it charged to 95% in about 45 minutes.Is this even possible?In fact in the past two days I have not gotten the charge above 95% at all.

Does anyone know which Sense ROM out there to use that has the best battery life? Or is there a Kernel? I currently am rooted with stock. I only rooted for wireless tethering and now I just want a ROM to have great battery life. Managing this battery has just become tiresome even with all the chargers I have. Not looking for tweaks and settings changes, just need a good ROM.

I rooted and put "Official Froyo HTC Sense ROM". Seems to work fine, however, I have a feeling that battery life is worse, especially when using the net. However, maybe it's just in my head. What are your experiences with battery life after upgrading to 2.2? And please, don't make silly "I surfed the web for 12 hours and still have 25% left" claims Also, I'm not interested in other ROMs, as I want a clean sense experience with no modifications (as close as possible to the way HTC made it)So - 2.2 and battery life: same, worse or better than on 2.1 that came with your Desire?

I can last a good 15 hours and still have like 50 percent. But when I don't use it the battery drains and barely lasts a day. I've been hearing that app killer is bad but if I don't use it I have no battery.

For those few whose battery life is actually not as good post-update have you figured out why yet? This is my first full day after doing the update last night and the battery is draining faster than it did before (even in standby). All settings are the same as before and I started with a 100 percent charge this morning. I am now down to 64% after 7 1/2 hours of light use. While that may sound like an improvement for some it actually isn't for me. Not a deal breaker but I would love to get my excellent battery life back (24-36 hours -- yes I am a light user especially when I am home a lot, which I am in the summer). The only thing different that I can see is that google talk doesn't stay disabled like it did before. Wifi is way down on the list of things using the battery and nothing seems out of place or not sleeping properly.

What started as a discussion over at XDA-Developers to try and resolve serious lag problems that some users experienced with their DHD is now proving to be a resolution to most of the problems reported with this device. Apparently turning 'usb debugging mode' ON is the resolution. The thread was first started by a user who noticed that whenever he was experiencing lag issues an Android process called /INIT was taking anywhere from 70% to 100% of his CPU usage. /INIT is a core process to the Android bootup sequence which should go 'dormant' after the bootup itself. What many users noticed after this was found is that whenever the lag problems started /INIT would take some 90% of the phone's CPU usage and not go back to its 'dormant' state. Even when the phone was idle and not being used. After applying the fix many people are reporting the phone running as smooth as they have even seen it running. Also users are reporting that recording video is no longer jerky and they can browse through the gallery smoothly and with no delays. The more relevant yet, and what may prove to be the best contribution from all this, is that some users are now reporting really amazing battery life performance. Its important to say that the so-called 'bug' doesnt seem to be HTC related but rather an Android 2.2 issue, as the performance issues are also being reported on other handsets running the latest Google OS - with some sources reporting that Google is soon to release an update to Froyo 2.2, possibly to resolve this bug. In order to turn 'usb debugging mode' ON go to: menu >> settings >> applications >> development.

First off, I didn't "find" this method on my own someone else did, I found it burred in other posts but it does seem to work for me. There are two ways to do this. One required you to dial a code into your dialer which I'll skip because the easy way is to just go to the Apps Market and get "Network" which is free. Then once you have it installed fire it up and scroll to the very bottom where you will see:
Set preferred network type. This is the VERY top option. If this is your first time running "Network" it's probably set to "GSM auto (PRL)".The problem here I've read is that Sprint does not have GSM networks so the phone keeps "searching" for GSM signals and it never truly sleeps. It might apprear to be sleeping but it's not, it looking for GSM signals.That said, change the setting to "CDMA auto (PRL)" which will set the phone to CDMA only and it will STOP looking for GSM networks and to go sleep like it's suppose to. That's if you have nothing else installed keeping it from sleeping.The only catch is, the setting does not appear to stick. If you reboot the phone, you have to restart "Network" and redo the setting. One thing to note is when you redo the setting, it will SAY it's still set to CDMA auto (PRL) but in fact it is not so just re-select the setting and close out of Network.I took my phone off the charger at 10am this morning and I've been using it on and off all day to send texts, Youtubed a couple video's made a 30+ minute call and a few other odds and ends. Normally I would have had to charge my phone again at least once threw out the day but I've NOT put it back on the charge since 10am and I was still at 83% power when I left work at 5pm.

First off, let me say that I love my EVO BUT as an ex-Hero owner, I am pretty much done with Sense. I am simply tired of the colors and layout. Although, HTC has figured out how to make a mighty fine bookmarks and calendar widget.I have tried LauncherPro and ADW but as most EVO users, battery life is a constant worry.Can anyone spell out how launchers and Android work battery wise? I have read that Sense is never really replaced so there would be an additional drain using launchers right? No offense but please abstain from any root related suggestions like 'just root it bro'

i just recently ditched my droid x for a droid incredible and like it a good bit. The only problem im having is that my inc has been off the charger for 4.5hrs and has 53% battery life. Why is my battery life so bad? I'm rooted running redemption rom, stock kernel, and the 2.15 radio update. Is it my setup or should i get a new battery?

First of all, for the most part,I like my Evo.It's fairly fast, good ui, and the screen is incredible.However, my battery life is worse than I would've imagined.I take it off the charger around 9am, go to work, use it for about 20 minutes total, kill the apps again before i get off break/lunch. By 5pm, it's dead. 20 minutes of use, and 8 hours standby should not kill ANY phone.Regardless of screen size, if it's 'sleeping' the whole time, it should make it through enough of the day to at least charge when I get home. This has made it so that I can't even use my phone, because I know if I do I have no hope of even getting home to charge it in the evening.I've thought of getting a second battery, but I feel like it's ridiculous to have to buy a second battery just to make it to 10pm if I actually use the phone a decent amount.How's everyone else handling this?

Can anybody advise me on which ROM's they run and the battery life that may get? Or, how to set SetCPU to get optimized battery life? Yes, I have read the SetCPU guide, but it doesn't really make any recommendations to actual profiles.I am currently running Ivans Official, and for me, with heavy usage, I may get a a day. I tried Plain Jane, but would only get about 8 hours. Should I consider a Froyo based ROM? From what I have read, they don't seem to be much better in terms of battery life.

Any idea on what is causing this. I've uninstalled most of my apps, disabled gtalk auto-sign in, disabled all syncing, updated the facebook app (which I dont use), and have been keeping the radios off and I still have much less life than with 2.1. I ran un revoked when I had 2.1. Did this break something? Is there another culprit? I went from being able to charge once a day to being forced to charge twice a day now.
