anyone feel as if their battery life sucks? I do have 4g on at all times but I didnt think it would make that big of a difference in terms of battery life.
See my post here:

Try installing a monitoring app and see if your init process is hitting the CPU hard. I haven't heard from any other mt4g users with the same problem, but lots of.desirehd users have it.
I also have seen my suspend process eating 50%+ CPU when the phone is locked/screen off. Haven't found a fix for that yet though.
I'm getting a full 24 hours of heavy texting, moderate phone calls. Battery life is better than my magic... im having no issues.
Yes, I woke up this morning and my phone was already blinking and battery is on 8%. I left it overnight with more then 60%
A big problem also is that SetCpu cannot force the scale. If limit to 768 Mhz it still scale to 1024. So not I am sure that my ScreenOff profile with 245 Mhz DOESN'T WORK!
THAT'S SUX!!!

Weird I leave my phone at full overnight and its still at full when I wake up.
Try disabling the preflock that might help before I did that it wasnt scaling properly now afterwards it is.

I have frozen a few apps and use advanced task killer every time i start up 9a lot of apps come on at start-up).
The result is pretty good battery life. I have only gone dead when I had a few apps (like GPS navigation) running in background and forgot about them.
I'm having 0 issues with my battery. It easily beats out the battery life on the Samsung Vibrant I had.
I'm having issues too. My battery life today was 40% at 1 PM, and when I left this morning, it was full. I hardly even used the phone except to check email :/ I have brightness on auto and wifi off. Not sure what the issue is.
My battery life has been really good. A typical cycle is charge to full and disconnect power at 10:00 pm. Up at 6:00 AM, battery is still on 100%. Today my use has been moderate to heavy. It's now 2:30 PM and I have 68% left. I typically have around 30 percent left when I put in back on the charger. I'm happy with that.
Wifi, Bluetooth, GPS, etc., are kept off until I use them. I do however leave Background data and Auto-sync on all the time.
I turned on USB Debugging as recommended and my battery life is much better. Right now it hasn't been charged in 9 hours and is at 79%. I've downloaded 2 apps, updated 3 apps, sent multiple emails, light internet use, and 3-4 calls. I'm unrooted and don't use any task killers.

That's awesome. I'm going to turn on USB Debugging mode and see if I can squeeze a little more juice out of it.
I have had intermittent battery-drain issues too. On Saturday morning my battery went from 100 down to 76% in a matter of an hour or two with hardly any use. I did a restart and it seemed better. I've also gotten into the habit of restarting my phone once a day, right before I take it off the charger in the morning. I've turned off quick boot, which I read somewhere in the forums can affect battery life. It's been pretty good the last few days. I'm at 68% now off charger for 9.5 hrs with moderate amounts of wifi, web browsing, email, and 3G network usage. I'm new to android devices so I don't have much to compare that to, but it's working for my schedule.
heavy user - fully charged phone at 7am ... start using after 7:30am
check emails, fb, txt, barely to no calls.....phone will be down to about 20% at 1:30~2pm....
yes the battery is lame...but this is a known issue with HTC...the 3.8 screen drains a lot of battery also the constantly searching for HSPA+ and 3G...
I do notice when screen is off....this phone still drains battery !!! bad =(
left over night at about 65% left in the morning I got red blinking led saying phone is below 10% .... 50% gone!!!
I think restarting the phone after a full charge is a good idea....also maybe turn off quick boot?
*update* yes I found that when you have a bad signal and it's jumping between E and H ... this eats up battery
also installed Advance Task Killer (for froyo) this helps~ now from 8am my phone can last until about 4pm getting about 3~3.5hrs more life
Mine lasts all day with everything on, playing games, email, text, etc, etc.
It is great, best phone I have had. Not sure what the issue is unless it is root.
It depends where you live.
If you get a good antenna signal, your battery will last.
At my apartment signal is low, so phone is constantly between UMTS and GPRS, plus phone is trying to hold H, so that drains the battery.
My signal strength parameters:
between -101 dBm and -107 dBm (where -110dBm is the edge of the signal/loosing signal)
3 asu and 7 asu
I know this has been discussed in the Gummycharge thread, but its buried pretty deep.
I know kej said that it has to do with the gallery, but I have uninstalled the Gallery3D.apk using the toolbox and I still seem to be losing about 10% per hour with the phone sitting idle on my desk.
Is there something we can use to quantify the appropriate battery drain rate? We all use our phones differently, so we need a way to standardize the battery drain so we can discuss it.
I saw someone mentioned that they were only losing 2% per hour while idle.
Currently, If i unplug the phone, and leave it sit for an hour (after a full charge) with only wifi on (gps, and bluetooth off) I lose about 10% per hour. If i use the phone at all, for example, When i wake up in the morning after a full charge and read the latest XDA posts, or some news articles, I can go from 100% to 85% in about 20 min.
this doesnt seem right.
Can we consolidate the battery drain issue to this post and post fixes and discuss reasons here?
This should have been posted in General first off.
Also, do you have SpareParts installed? If so, use that to check if your phone is entering sleep mode. You may have an app that is preventing your phone from sleeping, which will cause excessive battery drain like you are experiencing. My battery drain is <<1%/hr in airplane mode (I lose 1-2% over 8-9hrs in airplane mode) and when not in airplane mode, I'd say I loose at most 2-3%/hr if the phone is only sitting idle and I'm not using it.

OK cool, I wasnt sure if this was a general issue or not. Can a Mod move it? Or should I just delete and Remake?
Ive looked in spare parts and Im not sure where it would give that information, under battery history ive got running at 38.2%, screen on 25.2% phone on 14.5% and wifi on 100%
nothing mentions sleep mode

I get a drain of about 3-4% an hour if mine sits. However I leave it on LTE and at the office there is no LTE service yet. Yeah I'm just lazy......lol.
Curious on your SpareParts thing tho. I've never used it much really. Where does it show/display whether or not it is going into sleep mode. now I'm kinda curiosu if mine is correctly or not. Not that I'm very concerned about 4% and hr as I make it threw a full day fine. TIA

If it's not running, it's sleeping. You're battery drain is likely caused by wifi being one 100%. If you are leaving the cell radio on, LTE, and also wifi, that is 3 radios on all at once, draining power.

is that just an issue with the charge? with my Incredible, leaving wifi on saved battery as it did not need to talk to the cell tower and try to get a 3g signal. Also, Before I flashed, I was able to sit all day in school and still be at %80ish power.
I will see what turning wifi off does.. but to be perfectly honest. that seems a little inefficient, that would mean every time i turn on the phone to use it, i would have to turn on wifi and sync, then turn it back off again.
For example, since I wrote this post, my battery has gone from 87% to 70%. 17% in 66 min even with wifi on, that cant be "normal drain". And All i have done is looked at 2 text messages.
Please do not get me wrong, I am not complaining at all. but I would like to get to the bottom of this.
I was on my way to the store to return the charge I hated it so much, but after flashing gummy and your kernel, I love the thing more than any phone ive ever had. So please do not mis-judge my intentions here. I simply want to know if this is normal. In my experience with sell phones (Droid Incredible for over a year, Wife has htc thunderbolt, and now the charge both stock and now custom rom) It is draining much much faster than any phone I have used before.
If this is normal, then I will just deal with it.
I am going to put it in airplane mode for the next hour and see what happens
It is def something in connectivity. Still at 75% after 1 hour in airplane mode. going go turn on 3g only and check again in 30 min.
I was going through battery stats and saw that wifi ON was at 100% and Wifi running was also at 100%..
seems like maybe somethign is using my data. so if that is true, it should try while on 3g and I should get huge battery drain.
will report back
Dude you are NOT alone. my phone drains like a siv, when its nt even being used. I always have LTE off, unless i tether wifi and I always plug it in when i tether so i dont drain. Itll just sit and be idle with NO use and lose 30%. i have gps, wifi and bluetooth off..... wth? this phone is looking ro get returned if i cant sort it out. i cant sit on a charger all the time.
If you are running Gummy, the gallery thing should not be an issue anymore (he fixed it a few versions ago).
When you go into spare parts, go to battery history and change to sensor usage. That will tell you immediately if you have some app that is draining your battery (ie the Gallery).
For the most part the battery killer for people is network searching. 3G,4G and WiFi are all in the same boat in that they will kill your battery if your phone has to constantly scan for them. To my knowledge using WiFi is better on power than 3/4G, but that is only if you are connected to a good signal and your phone doesn't have to search.
Also, I have noticed that the WiFi antenna on my charge isn't all that good, so you may want to keep an eye on it during your day. You may find that it is losing WiFi and scanning without you realizing.
The LTE radio in the Charge can be a huge hog. Especially if your in an area that likes to switch between 4G and 3G. Both my work and my home switch between 3G and 4G a lot and its not uncommon to see my phone drain almost 10% in an hour. On a good day it will be 5% an hour with LTE enabled. With mobile data and wifi off it can go down 0-2% per hour.
As far as I know, this is most likely just a sign of the Charge's battery. I'm not sure what Engadget was smoking in their review, but my Charge gets pretty horrendous battery life, especially in areas with dodgy signal (think constant switching between 3G and 4G). This is the first phone I've bought extra cables for charging in the car and office, but honestly, with these things getting as crazy as they are, I think this might be the norm in the future, what with battery technology lagging behind so much.
Some tips I've learned: turn the Wi-Fi radio off when not in use, and if you're in a really low-coverage area, consider even turning data off (you'll still be able to receive calls).
I live in NY, which is absolutely blanketed by 4g. I get better 4g reception than 3g in some places. I am getting horrific battery life. I just wiped, then mounted each partition individually and wiped and then reinstalled gummy 1.8.5 and per imnuts' recommendation, not install the reboot options. I had a custom rom on this phone within an hour of purchasing this phone, so I can't compare stock to a custom rom's battery life. I just know over the few days I've had this phone, my battery has been terrible. I shudder to think what the Thunderbolt must be like.
Your battery may be draining fast the first boot. Just reboot it. If that doesn't work then it didnt flash properly. Just reflash everything and remember to clear data, cache... hope it helps.
You can download an overclocking app and reduce battery use IF you already solved the battery drain problem.

I recently bought a g2x. I previously had a Optimus v with cm7 that I liked, so I pretty much immediately installed cm7 on my g2x. I've noticed my battery will drain 25% on stand by overnight. Just wondering if this is normal, and if the stock rom is any better in this regard?
Well...its normal but at the same time its not, and i'll tell you why. Mine drains about 5-10% overnight (around 7 hours) and with wifi on it is usually even less, about 3-5%.
Though there HAVE been instances where it has drained about 20-30%, usually I just pull the battery (or restart the phone a couple of times) and it seems to fix it till the next time it happens.
In fact just last night it drained 35% =\ but normally it is around 10%.
Im on weapon G2x
My phone drains about 3% overnight. Wifi and data off. CM7 with Faux kernel and setcpu screen off profile.

It honestly depends what kind of network signal you're getting.
I've had mine drain a considerable amount one night just because I had low signal. Especially when you have low signal AND data on.
Mine drops 5-10% at night, sometimes less. I either keep it on 2G with data off or wifi with wifi calling on. Wifi calling seems to save a ton of battery.
But, leaving data on and 3G on I drop 30% or so.
yeah, as everyone says, depends on your usage (and/or signal). i've gotten 12h, i've also had 4 days, it really differs on lots of factors.
Seems to be losing 3-4% an hour with phone on screen off..
Is this normal? just sitting idle without touching it..
That's sounds about right...some ppl are reporting on averages its about 10% of battery life per hour. On the stock Rom. Go and check out the battery life thread

No, that's not right. You have an app eating your battery, with your screen off you should average 1% every 2 hours, 1% ever hour, MAX. Unless you have WIFI doing something crazy or a terrible terrible reception you should have really decent idle life.
With 1 bar of LTE here (constantly switches itself between 1 LTE and 3 bars of 4G where I live) I can have a battery last 9-10 hours of relatively heavy usage (calls, texts, browsing, games, downloading, etc.). I flashed Da G's .3 kernel and it increased my battery life drastically.
I still have something eating battery under Android System, it shouldn't be THAT high, IMO.
Here is my screen shot.. something is strange.. have these broken lines...
Have frozen Noled as of now..
Seem odd?
* I think Noled was the culprit.. will charge to 100% and wipe battery stats and drain and check again..
Seems it was keeping phone "awake" at all time with Noled..
Noled was the problem.. its gone.. Rocket is back in action again.. 5 hours and 96% left
If anybody is using Noled.. be careful with it.. if you are experiencing high battery drains.. look there first!
The ROM I'm using (TPC v3) for some reason won't put the phone into deep sleep when wifi is on, so I have to turn off wifi AND mobile data (leaving that on is like leaving wifi on, it's LTE) to get it to go into deep sleep.
I should flash a new ROM and see what happens.

Hi everyone,
I noticed that my One X has been losing about 12% of battery life while asleep for 8 hours (while I'm sleeping). Is that normal? How much battery life do you lose when you don't use the phone? I leave wi-fi on and that's about it. I checked to make sure that the phone isn't awake during this period.
My battery life has been good on some days (lasts about 20 hours) and bad on some days (lasts about 10 hours) with almost identical usage. Any tips on improving battery life?
I went camping and put my phone on airplane most 80% of the time except when I needed it. It lasted me nearly 3 days! Does LTE consume a lot of battery power? Does wi-fi do also?

Yes to both of your final questions. LTE uses a ton of power. I went to the San Jose area where it's only HSPA and my battery was phenomenal. Wifi may drain significantly if "best wifi performance" is enabled in advanced wifi settings.
Check what uses your battery overnight. What process does it say under power in settings? 12% for 8 hours isn't really that bad..

Wifi consumes the least power of all, but like the post above says, if you have "maximum wifi performance" enabled in your advanced wifi settings then it will prevent your phone from going into deep sleep and drain more battery than it would if that option was not checked. Overnight I usually drain about 1% an hour or less (on both CleanROM DE and AOKP M6.2).
I think it's not LTE drains the battery. It may be because of searching of networks when signal on LTE is bad.

It's sort of both. When you have a good LTE connection while using data then it uses up more battery or if you have a poor connection without using data you will use even more battery or if you have a poor connection while using data that would be the worst for battery. But if you are in a good coverage area and not using data then the battery should be fine.
Drain of 12% over 8 hours (1.5% per hour) of screen off time is pretty damn good. Certainly nothing to complain about. I get somewhere around 2.5% per hour overnight.
Phone battery last forever when in airplane mode. The phone radios are a big consumer of power, often second only to screen-on time. Way back, I had my old HTC Tilt2 in airplane mode in a location with no cell service (basically just using the phone as a watch and camera), and it was on track to last about a week (maybe more) before needing a charge.
12% is what I get overnight. But If I turn off WiFi before sleeping then I get around 5% loss so turn off WiFi if you need more battery.

I feel that most people would get better battery with WiFi turned on. It seems the area you place your phone overnight is not getting a good WiFi signal and/or you might have some of your settings to sync or download while on "WiFi Only".
It varies from person to person and it usually ends up being something in the settings, specific apps, and/or quality of connection (mobile or WiFi).
