So like everyone else my battery life sucks. No big deal. I bought the extended battery from Sprint, and I can see the battery diminish in front of my eyes. I mean dropping 1 percent per minute. Is there a way to test the phone to see if it is the culprit?

ther are lots of ways to check things. does it drop 1% a minute all the time meaning you only get 100 minutes? does it only do it when you take it off the charger at 100% where ti will drop to any where from 99-90% in a matter of minutes?
if the later then thats normal and is because the phone doesnt have a trickle charge. this means that the phone charges your battery to 100% then stops however the indicator on the phone will not change it will still show 100% once the acctual power reaches 90% the phone then charges again up to 100%. what this means is once you take your phone off the pwoer if it has been sitting there even if it says it is at 1005 it can be any where from 90-100% which the battery quickly changes to over first few minutes.
If it happens past 90% and all the time then something is wrong and you likely have at least 1 if not more apps running wild on you, you have things set to sync constantly, and you have everything under the sun turned on for your phone.
for apps the paid version of system panel is very nice for monitoring you can go to monitor top and top apps and see which apps are using the most battery/cpu.
witht he information you have given that is aobut the best i can tell you. I would not say everyone has crappy battery life with the evo as i have slowly gotten my phone set up and now with moderate usage i can get 14-15 hours and at least 8-10 with very heavy usage(stock battery) which i dont consider to be crappy battery life.
I appreciate the response, and I forgot to add that I'm running stock unrooted sense. This is not my first Android phone so I know about battery managing. I don't have everything sync every two minutes nor do I have everything turned on. It does drop rather quick even past 90 percent. I think it might be the phone it self. I doubt I got 2 bad batteries, one being extended. I'll see if I could get a device swapped out.

My first EVO was like that. It drained quickly shortly after charging. I could never figure it out. Till one night before going to bed, I noticed something weird about the bottom keys on the phone. They were " very dimmly " lit. The home, menu, return, search were all dimmly lit. It was I believe a defect in the phone. I got it swapped out. No problems like the 1% drain since then.
First, my setup:
- EVO 4G hw rev 0004
- Fresh EVO ROM 3.5.0.1 (basically not a whole lot more than a rooted version of latest OTA)
- netarchy havs more no sbc kernel 4.3.4
- stock 1500 mah battery
- stock charger
So I reset my battery stats on last Friday (it's now Monday) in the recommended fashion (charge to 100%, get as close to 4200 mv as possible, wipe stats, unplug phone, use until dead). I charged my phone overnight last night to 100%. Unplug from charger. Get on the subway to work. I have service in the subway stations but not in the tunnels. I'm listening to music on the subway the whole way. Phone gradually gets warmer and warmer. By the time I get to work, the battery reads 59%. The entire subway ride takes 45 minutes.
So in 45 minutes, my phone dropped 41% of it's battery charge. This seems unreasonable to me, even given the fact that I was going in and out of service and listening to music. I'm beginning to think my battery is dying/going bad (especially given the amount of heat generated by the battery). Before I complain to sprint or buy a new battery, I wanted to get some feedback from other EVO users who have maybe had similar experiences.
So does this 41% in 45 minute battery drain seem normal or abnormal, given the conditions states above?
I believe the reason why your battery is dying and getting hot is because it keeps looking for signal. Next time you charge your phone and get on the train put your phone in airplane mode and see if that helps at all. I know in my house before I got the airave i barely got any signal which was hurting my battery life.Then once I got the airave and always have full 3G the battery draining problem was gone.
I mean yeah I get that, but 1% per minute average? Really? That seems a little ridiculous.
Anyone out there willing to stick their phone in a lead box or some other service-less place for 45 minutes and see if you lose 1% per minute?
Absolutely possible. Searching for a signal uses a ton of battery, hence why your phone is getting hot. The phone can easily drop 1% per minute when searching.
Simple solution: turn airplane mode on while in the subway, turn off when you get out.

When I was on CM7 without working GPS, my phone would get freakishly hot if GPS was turned on. The battery would drop about 1% per minute as well. I have working gps now on MIUI and while the phone gets warmer, it's nothing close to what I was seeing on CM7.
I guess yours could be something similar.
I would like to recommend an app from the market called juice defender. It works wonders. Just get the free version (not the beta) and set it to balanced which is the lowest setting. It saves me so much battery.
Hey guys, I just got the droid incredible 2 and I first had the LG revolution but the 4g and the screen size made the battery drop down quick. I played with it for 20 minutes after it being fully charged, changing settings, and the battery went way down to about 80%. So I exchanged it for the HTC Incredible 2. They told me the batter was way better.
I went to the Verizon store to tell them the batter dowesn't last as long as expected. My Iphone 4 would be on all day, texting, pandora, email and web browsing and I still came home from work with battery left. My droid gets used from 7am to 1pm and its pretty much dead by then. They made me change the background data off, sync only email and weather, and download juice defender.
The batter still dies by 12:30pm after charging all night.
I have read all over people are getting excellent battery usage but I don't really know what to do to get the same. It is not temp rooted. Any ideas? Also, at work, in the building the data coverage is not so good so I usually do nothing but text on it and it still dies by 1pm.
I can't really say how well mine would do on the standard battery because I bought the extended battery immediately after getting the phone. I've been unplugged almost 15 hours and have 38% battery and I have sent/recieved 40-50 txts, 20 mins phone, browsed internet for 30-45 mins, played games around 30 mins, and listened to pandora for around 45 mins.
I would recommend the extended battery, it's $50 at verizon and I haven't even come close to killing it in a day.
Does the extended battery make the phone bigger? I'm thinking it would be thicker on the back. Would it have any drawbacks as to cases and stuff like that?
I'm not sure why mine is so bad, prolly because I am in a secure building and signal doesn't get through constantly. I'm surprised, I thought my iphone had bad battery.
the extended battery does have a thicker back. and yes, there are currently no cases for it, so there would be an issue there if having a case is very important.
as to your current battery, if your in a biulding with bad signal, that will most defintiely affect your battery life as your phone will have to use more battery to try to find a good signal. additionally though, the phone battery does seem to improve after about a week of charge/discharge cycles. not sure why this is, but i have seen it on my phone and seen many other report the same.
The battery sticks out a little more than 1/8th of an inch I would say. However, IMHO it protects the camera lens and flash lens from getting broken and I never really like using a case anyways.
I have amazing battery i charge it to 100 percent unplugged after then go to school texting 100-200 average everyday internet music by the time i get 3:00 i still have 80-70% and i'm 13 so imagine how much i use it and it still stays at that percentage
Having a phone in a building (or anywhere) the signal is weak is a drain on your battery. If your iPhone was with AT&T the signal may have been stronger where you work than with Verizon and may have therefore contributed to better battery life.
Also, if you didn't FULLY charge your DInc2 and FULLY discharge it right when you got it, you should really do a factory reset and immediately do the following:
Charge the phone for at least 8hrs with the power off, unplug for a few minutes, plug it back in. The light should only remain red for 10-20 seconds before turning green, otherwise this unplug-plug part should be repeated a few more times always letting it remain on "green" for an hour before unplugging an plugging back in.
THEN power up and use the phone until it shuts itself off because the battery is drained. Let it sit for a few minutes, and turn it on again. It should sut itself off again pretty quick. Let it sit, turn on again. Do this until it wont power up at all after sitting untouched for a few minutes and your battery is then fully discharged.
Now you can plug it in and start the charge part of the cycle as lined out earlier. Once the light turns green 10-20 sec after plugging it in again you have completed one "cycle".
This may sound excessive, but I'm kind of a nut about this kind of thing.
I didn't do anything special when I got my I2, am a realtively heavy user, and have an all day battery life. I'm pretty careless with my features being left on.
If you can't get it to last all day, either you are a much heavier user than I am or you do, in fact, either have a battery problem, or a battery calibration problem. You shouldn't need to calibrate the battery algorithms, but I guess it doesn't hurt to try.
I wouldn't say I am a heavy user. I normally text while I am at work and check facebook a few times. I also listen to pandora most times. I work for Vanguard and most people here have Verizon I believe. I was told when I switched from AT&T that signal should not be a problem where I am at. My Iphone 4 would get used much more and it too would have signal problems as well until I turned 3g off but it would last way longer than the droid.
I guess I can try the factory reset and full charge cycle this weekend but I'm not sure what Verizon can do for me either so it may just stay like this
this is bump charging no? (well the part about how to charge it). i spoke to am htc rep that said that bump charging will significantly decrease the lifespan of your battery life and therefore is highly not recommended.

I just got mine on Sunday, but even yesterday I was texting and surfing a fair amount yesterday and went to bed with the phone at 61%...
I am sort of amazed, I think Verizon has taken the underclocking thing and put it to work on the official release... at one point I turned off the screen for what amounted to an hour and when i turned it back on it was still the same battery level.

if your comparing battery life on the dinc2 with 3G on versus the iphone with 3G off there will also be a pretty big difference. if your tuirn off 3G on your dinc2, i would imagine battery life will be similar or better than your iphone had with 3G off also.

No I was comparing the Inc 2 to the Iphone with 3G on. My iphone would also last longer if I turned 3g off and just used Edge or whatever it is called. I don't think I can do this with the droid until it is rooted or download an app to do this.
I turned off juice defender and we will see how it goes today. I don't really like apps running in the background and it was turning off data eacht ime the screen locked.
I think the biggest difference is the verizon signal. The battery on this phone is amazing for an android device. While it is still nowhere near iphone 4 status as far as battery, it shouldn't drain like that. Have them either swap you a battery or the phone itself.
I'm a relatively heavy user. Especially with voice calls and I can go a day and a half easy.
But I also run launched pro with only a couple of widgets. To me sense is a battery hog.

What would I do to go about swapping out the battery or the phone itself? Should I go back to the same verizon store? Or call them on the support line and try to get a battery or new phone that way? I have no clue why it is draining like that either, the signal can't be that bad, I literally had the same signal with AT&T in these buildings.
Well, lets be honest, one of the things Apple really puts a lot of time and effort into in their development is long battery life. It wouldn't surprise me to see the iphone outlasting most Android devices.
In any case...
While I don't need to, I do charge my phone while at the office. If you have a desk job then I don't see how this would be problematic. My work day usage includes 2 hours of bluetooth streaming (in my car to the stereo), media playback (music/podcast), and mapping with gps and 3g data (this drains my battery pretty quickly, but that's relative...it's about 15% per hour). Outside of that, my battery drain is quite low.
I only started charging at the office because I like to keep my battery as full as possible in case of extended emergency that requires being away from a charging source. It's that whole boy scout be prepared mentality I have. Besides, if you have the opportunity to charge, why not? It seems to charge pretty quick anyway.
I can charge at the office, but normally I forget the cord at home. Not a problem to buy another one but still. I was just concerned because I hear people getting 15 some hours on one charge and as of right now, my battery is below 50% since I just got back from lunch.

take it back to the store, and if that doesn't work then call. but the store would probably be a better bet as they can give you a new phone or new battery there whereas the phone support, you'd have to wait for the shipment.
Seems as if they were not able to help in store the first time. Rather than have someone check it out, they had someone come over and tell me I should turn off all the sync and data features. So I did do that, but then why did I get a smartphone?
It's possible you have an app that is not allowing the device to sleep. If it can't sleep, it will drain the battery much faster. You might get 8 to 12 hours awake yet idle.
Are you using many third party apps? If so, have you considered going through them, removing them one at a time, until you find the battery doesn't drain so fast anymore?
If you go to About phone in settings, then Battery, the last item will show awake time. This should be much lower than your Up time.
Bit of a preamble...
Because I'm a stickler, I spent a while getting used to my device when it was stock and eventually with medium to heavy use I was getting 36+ hours out of the battery. It nearly always hit 1d 12h before I even considered recharging.
I then went with Gingerburst and was delighted to see that the battery life remained the same. Now, Gingerburst wasn't happy with my class 2 SD card and Sense restarted all over the place, before eventually crashing in such a way that I had no choice but to wipe it to get functionality back. I fancied a change anyway, so flashed Miui to my phone.
At this point, battery life went to the knackers...first run through on Miui was a mere 10 hour battery life. I stuck with it for a few days but it didn't improve, and a couple of other things irritated me as well. (Another story)
I've since gone to Ginger Villain, and although the battery life is a bit more than 10 hours - more like 18 - it's still nowhere near what it was. For example, it's on next to me. Wireless data turned off, just mobile signal and wifi for the last 15 minutes, and it's shed 7% in an hour and a half. By that reckoning I'll get 20 hours out of it.
Looking at the battery usage curve - on stock and Gingerburst, it'd barely decrease, being more or less a horizontal line, unless I started doing things, whereby it'd steepen. It seems like since flashing, it follows a steady decrease at a steady rate whether I'm doing something or not.
I've recharged to full and wiped my stats to recalibrate but so far, very little change.
Any ideas what's caused this, or how I could fix it? It's very frustrating to have to charge it so often again!
(P.S. Oh, and another reason I'm irritated enough to post - it went flat from 39% overnight. Whilst on airplane mode. Which meant my alarm didn't go off! When on airplane mode before this started, it wouldn't shed a single percent point overnight!)
I cant tell if it's always been like this. Or if this actually isn't normal because I'm always concern with battery life. Im a very heavy user in the sense my phone will be on and im texting, xda, social apps i.e google +, email check every hr, and twitter.
However, i started feeling like my battery has been draining alot faster when the screen is on. I have no problem with the phone sleeping. I was experience this on Calk rom and now acs ics rom. I literally can look at my battery percentage drop 10% in like a half hour. Is this normal if screen is on the whole time? I've used better battery stats and system panel I can't find anything causing the drain. I see the suspend and events but doesn't that effect the phone sleeping?

Are you on the new modem? Looks like you have weak a signal. EG31 might help a little if your not on it already. I used the full EG31 tar right when it dropped and have been getting great battery life (it may be to early but so far so good)

not sure if its going to work but hoping it does thanks for the response still
turn your display down to under 50% you won't see a difference except outside in daylight and kill this app every time you reboot the phone hit Settings>Applications>Running services then hit DRM content > stop > ok
I get over a day on one charge.

Ok ill try the drm content stop..however my display brightness is already down at like 10%.
Also, kill the Social Hub as well, that drains the battery significantly.
You might try one of several roms available in dev. They address most of the aforementioned issues.

The biggest battery drain reason is the location by wireless network option. Make sure its unchecked. Ever since I did that, my battery life has been awesome. I get to keep my brightness high, Bluetooth on, etc...

All the basics (brightness and all that stuff) on top of the stuff you have running. The darn task killer/manager I see in the icon top left of your screenshot is a HOG on resources check the caching... You can literally **** with these phones for half a day to set it up the right way to conserve. I think wireless is hogging too but I am talking primarily about the first part of your rapid loss, the left part of the graph so to speak.

I purchased an extended battery and was still getting crappy battery life. SpareParts always FC'd on me... but last night I found Badass Battery Monitor in the market and in my opinion it's even better than SpareParts!
It helped me find that the Hotmail app was keeping my phone awake for almost an hour every day even though I had it set to download email only once a day. Removed that right away.
Plus it gives a great % readout in notification of the battery level. I think it's a fairly new app, but it really is worth checking out especially if you're having battery drain problems.
Just killing Social Hub has increased my battery life significantly. I'm at 11 hours now on battery, with 62% left. This is from last night when I unplugged the phone at 100%.

I'm on the Sydnicate Rom there isn't even no social hubb app. He has alot of the mods like noCiq and everything. My phone sleeps well its just when I start using it I can see it basically draining like 10% every half hour. I'm a heavy user I know my phone will drain fast while I'm on it I just would expect it to last 8-10 hours on heavy use.
Right NOW:
I'm at 4 hours 12 mins 22 secs at 37% left.
Display Time is 50% 2 hrs 41 mins 51s (Brightness is set all the way down)
Android OS 10%
So I'm assuming in 2 more hours my phone will die. If this is just normal for a heavy user then I guess I have to deal with it?
I was very disappointed with my Epic Touch when I first got it. I was getting a dead battery in about 6 to 8 hours no matter what I did or did not do.
Calibrating the battery seems to have fixed it.
I'm at 73% battery with 8:32 hours up time and I've made about 12 calls ranging from 2 to 10 minutes.
I've also checked voice mails, emails and other stuff.
I just charged the battery til it was full, plugged and repeated until it stayed at 10%, popped into CWM5 and cleared the battery data and then used Battery Calibration from the market (free) and it's like a got a battery upgrade!
As far as wake lock issues, I've not having any of those. I took my charger off the phone around 3:30am this morning (100% charge) and when I left for work at 6:50am, I had 98% battery still.
When I got to work it was down to 96%, I checked my email on the drive there.
I'm trying this out, wish me luck.
There doesn't seem to be any possible way to charge my battery to 100%, unplug it and not have it immediately drop to 99%.

If those screens are both from the same charge, I see nothing wrong with your phone.
you have 17% left, and you have 2.5 hours of screen on time. So you're on target to get just over 3 hours of on screeen time which is completely in the norm for these phones. AND you're over 12 hours. I don't understand what else you could ask for?
People get all caught up on total charge time, but, to be honest, it's completely IRRELEVENT.
If I dont use my phone I'll get easily over 48 hours out of the phone... Screen on time is what matters. And from a full charge, if I were to use my phone for 4 straight hours without stopping, it would be about dead. When the screen is on, you're using the phone, and the display is the biggest battery suck out there. When I do all the tricks to conserve battery, and I set it up right, I get 4 hours screen on time, which is pretty incredible with these phones.
Now, If you WANT to get better then you have right now, a few things are coming into play.
1) Your signal is weak, this will suck power no matter what more then it should, so get better signal if you want some more time out of your phone.
2) If you installed a new rom, and you didn't calibrate your battery properly, you're losing battery life.
to calibrate properly:
a) download battery callibration app from market
b) charge to 100%
c) unplug battery charger and REPLUG IN and wait for 100%
d) repeat step c a couple times
e) while plugged in hit the calibrate battery button in the app
f) unplug phone and use til dead and recharge
This will yeild you the best battery life.
3) De-Theme. Although I use a theme, every theme I've tested, for one reason or another, drains my battery faster then running the stock phone theme.
4) If you haven't done the basic battery saving things, you should do them to help yourself out. Here's a few I use.
a) Turn off background data, you only need it on to use market
b) Turn off, or set sync for all email and social apps at as long intervals as possible
c) dont use any widgets
d) download watchdog lite so you can see when apps are acting up and using extra battery
e) when you're done using your phone, open task manager, kill all apps, and clear memory
f) always leave the brightness off automatic and as low as possible
g) download SETCPU and run your phone at 800mhz, and undervolt as much as possible (50mv most all phone can take)
h) use black or dark wallpapers, on LED screens back means the pixel is off which uses less battery
G will be your biggest battery save. I've also tried using the SUPERFREEZE thing in the dev section and, besides in sleep mode, I saw no adverse effect. If you wanna kill socialhub, fine, but I dont see any noticable difference on my phone with it off.
If you do all these I promise you'll get better battery life.
Wow, I did a proper calibration today and I'm getting great results already. I've calibrated before but I never had cleared stats in CWM or did the unplug then replug charging thing.
Anyways, I after 12 hours I'm still at 35%! The longest I've ever gone before is 12.5 hours. Screen on time = 1 hour 30 min, but some of that was a battery intensive game (puzzle quest 2). Also i'm running calk's rom, so i'm sure that helped.
Thanks kdoggy, i didn't expect to see results this great.
Those are good tips too Jermzz, thanks!
