sorry for the low quality image, i actually have a decent camera but i guess it doesnt take low light pictures very well

this is just testament to how bad sprint is in my area :(
[HTC EVO 3D] empiire:
Hmm... My 3G drain is pretty incredible. I can't tell you how good/bad my signal is since Sense doesn't show actual 3G connectivity strength, but I usually average 1-3 bars in my area and my battery absolutely taaaanks when I use 3G. Also my phone gets pretty heated when using 3G (same problem for anyone else?) so that leads me to believe it's trying fairly hard to get signal in my area. Where do I go to change my CDMA roaming code from Home/Automatic like my old Evo 4G had? Is there even that option? But otherwise, I average 5-9 hours depending on my usage. Kind of frustrating but better than my E4G and that's the price you pay for dual-core. :)
[HTC EVO 3D] Androidfreakz:
I've gotten 17hrs of light to moderate use, moderate to heavy is 9hrs to 12hrs. I'm very happy with my battery life. Awesome phone too.
[HTC EVO 3D] borgqueenx:
I seriously do not believe with heavy use, some of you guys have 9 hours. My iphone 4 is 6 hours TOPS/RECORD when heavy used.
[HTC EVO 3D] draghn:
My battery life is pretty good, about 7-9 hours with moderate usage. I have juice defender as well. I've never directly measured/monitored my battery though.

Also, I've been really enjoying Battery Monitor Widget. I have a circle indicator with current showing right now. Has graphs, etc. If anyone was interested:

"Battery Monitor Widget"

[HTC EVO 3D] borgqueenx:
we need screenshots or photo's of results people! show what you've done or say it when giving your battery life please!

this will help people who need to choose alot :)
[HTC EVO 3D] Genjinaro:
I consider myself a heavy user.

I don't turn anything off on my EVO, on some rare occasions I'll toggle off 4G if I'm in Atlantic City the only place I've ever been to that didn't have 4G.

I usually go between 6-7 hours. Never made it to 8+. 4 Hours if I'm gaming (i.e. Asphalt 6 3D, NOVA 2 HD, Assassin's Creed 3D etc.).

Updates are set either to push or the lowest frequent intervals.

With the exception of FriendStream items, I have those update hourly.

The only battery advantage I noticed is that 4G doesn't hog it on here unless it's scanning. Once custom kernals are available I should be able to get another 1-1/2 hour in.
[HTC EVO 3D] dakidobf:
When I first got my OG Evo, I used to be consumed by battery life. Always checking to see whats running, how many hours I'm getting etc. It really took away from enjoying the phone. Instead i went to ebay, spent about $20 and got a car charger, 2 extra batteries and a wall charger and just forgot about the battery. I kept a charger at my desk at work, one in the basement. After a while I couldn't care less how many hours I was getting. If it go low, i'd throw it on the charger. If I knew I'd be out of the house for a long time, I'd take an extra battery with me. Doing the same thing for the 3d. Simple. Also, its a good idea to adjust your usage according to whether you'll have access to a charger. if you know you're gonna be out all day, and don't have a spare battery, turn off your radios, don't watch a ton of youtube videos. Just be smart about it. battery tech hasn't caught up to phone tech yet so you can't expect to be a heavy user and get 15 hours out of your battery, its just not going to happen. But if you monitor your usage when you need to, and keep a spare battery or a charger the rest of the time, you'll enjoy the phone a whole lot more. Just my $0.02
[HTC EVO 3D] borgqueenx:
if i can get 4 to 5 hours while playing games with all antenna's and functions on, i call myself a very happy man.
[HTC EVO 3D] rgloria12:
are you serious? I surfed the web with my evo 3d for about 30 minutes and the battery went from 99%(it never gets to 100%) to about 75%. do you guys think I got a defective phone or battery?
[HTC EVO 3D] Eric1985:
Idk but my battery is amazing I'm at 75% after 9 hrs normal use FB, net, browsing the market always on WiFi tho
[HTC EVO 3D] Xencer:
Netflix rapes my phone :p
[HTC EVO 3D] Torrentula81:
Close to what i get.
[HTC EVO 3D] Drachen808:
All of a sudden the day before yesterday, my phone started just draining battery like crazy. I was getting (on average) about 15 hours a day. Now the past two days I have been getting about 6. Two days before this started I installed juice defender and it rocked my socks for 1 day (dispay on for 3.5 hours, 1 hour of voice calls and I plugged it in 17 hours later at 21%). The day after that day was when the problems started so I disabled juice defender today and there is no difference. Any ideas? (usage hasn't changed)
[HTC EVO 3D] spencer88:
Check for wake-lock. My original 3D all of a sudden started having that and I had to do a factory reset to fix it.
[HTC EVO 3D] Drachen808:
appreciate the response spencer, how do I check for the wake lock issue?
[HTC EVO 3D] ShadowDrake:
To weigh in here and say - I was skipping on the OTA update because I wanted to root eventually... since the temp root works with both, for now, and HTC says that the bootloader will be unlocked soon enough, I just updated anyway.

My battery life since the update is absolutely phenomenal. There's very very poor service at work... typically, spending 10 hours there would render my Evo 4G from just off the charger as I was walking in the door, to about 15-20% by time I'm out with, most of the time, zero usage, just standby time. The Evo 3D is a little better, I'd have about 35% remaining under the same conditions.

I took the OTA update and walked out of the door yesterday with 86% battery left after 14 hours. I'm still on the same charge and I'll probably go do it again today, and tomorrow... Maybe even the day after. If some of you are getting bad battery life, just suck it up and take the OTA update.
[HTC EVO 3D] Drachen808:
Thank you for the advice, but I just checked for a firmware update and it turns out I have the newest version.
[HTC EVO 3D] spencer88:
Go to Settings=>About Phone=>Battery

and look at the "Up time" and "Awake time" stats. The awake time should be drastically lower than the up time. if they are both exactly the same, that means the phone isn't going to sleep when you turn off the screen, thus consuming lots more battery.

I had that issue on my first EVO 3D and only a factory reset would fix it.
[HTC EVO 3D] Drachen808:
Ah, ok. My up time is 2:36 and my awake time is 1:01 (I have been on battery for 4.5 hours). Display is taking up 65% of the battery and has been on for about 1 hour. I am currently at 55% battery life. Pretty much everything looks pretty normal (outside of the 55% number). I don't get it.
[HTC EVO 3D] spencer88:
I would still do a factory reset, somethings up. I get phominal battery life throughout the day
[HTC EVO 3D] Drachen808:
I will give it a try. Trust me, I know all about how good the battery life is on this thing. My wife has been giving me dirty looks (and not in a good way) every time I have given her examples of how good the battery life is on my phone. She got an OG Evo in March and finally gave me permission to root it in hopes of being able to get better battery life on June 5th . . . . . Right after the OTA update..... LOL!
[HTC EVO 3D] TheGamerAccess.com:
Battery life seems solid for me, except for when I play games.
[HTC EVO 3D] supersund:
I am at 43% left after:

- 9hr32m on battery

- 1hr21m display on

Everything ON but 4g. That sounds right to you guys?? Coming from a Blackberry that I would charge like every other night, the EVO 3D has got me paranoid about battery life!!

Thanks!

Edit: just got home. New stats:

5% battery left after:

- 15h 35m

- 1hr 43m display on

And i even turned off all the radios at around 20%.

Normal? opinions?
[HTC EVO 3D] sudhirkhanger:
12-14 hours for medium to heavy usage.
[HTC EVO 3D] borgqueenx:
100% bull**** unless you use a extended battery or use the charger.

Or with heavy usage you mean checking and writing emails thats it.
[HTC EVO 3D] Coslaw:
Am i considered a medium or heavy user? i made or got 3 calls all together, 19 minutes of talk time, took 7 3d pictures, looked and showed everyone the 3d example pictures and green hornet many times, checked facebook a few times, texted around 200 times, 3 pictures. Any who, I got 8 hours and 4 minutes and that brought me to 15%, that is with all radios turned off. My screen online time was 2h 16minutes. i didnt play any games. Any who, is this battery life poor? it is no were near 12 to 15 hours... I heard resetting the phone can help, maybe i will give it a try.
[HTC EVO 3D] LostRib:
You need to say what that means for you
[HTC EVO 3D] aledc78:
People need to understand that light, medium or heavy use is only your perception and opinion. What someone considers heavy, i may see it as light...

So pls describe you actual usage with details
[HTC EVO 3D] borgqueenx:
This. Please tell us people.

I call heavy usage having all radio's on, and playing a 3d game, without screen off.

Medium is surfing mailing texting, without screen off.

Light is surfing mailing texting quickly. When message is send or i found the info on the web i wanted its standby again.
[HTC EVO 3D] bgmikejr:
To help with battery life please do the following steps:

1) Turn your device ON and Charge the device for 8 hours or more

2) Unplug the device and Turn the phone OFF and charge for 1 hour

3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour

I have done the above and I have Juice Defender installed as well on my EVO3D and I get around 24-30 hours of battery life with moderate usage and 15-20 with heavy usage. Hope this helps :)
[HTC EVO 3D] nabbed:
Your heavy sounds like my lightest usage.

How about playing Angry Birds nonstop with autobrightness on. Just as a test.

How many hours would that be?
[HTC EVO 3D] freeza:
What a silly amount of unneeded steps to achieve nothing. :P
[HTC EVO 3D] ajones7279:
I'm at 26 percent now after 12 hours of moderate usage. Display at 67% Lots of Twitter, texting, and web browsing. I tend to get 12-15 on average though, enough to get me through the day and not have to charge it again til I get ready for bed.
[HTC EVO 3D] Joey121215:
Okay I get 3-5 hours on battery, THAT'S ALL! My battery drains insanely fast even if I turn my radios and background applications off. Anyway here are my current settings, I'll show a screen shot in three hours of my nearly dead battery with the settings starting at 98%.

My settings are:

Auto sync on

Auto brightness

WiFi on

4G off

Bluetooth off

GPS off

Mobile network on

Twitter: five minutes

Facebook: one hour

Skype: on

Go!Chat: on

Tango: on

Qik: on

Fring: on

Weather: three hours

Stocks: one hour

Google: on

Kaiten with google: push five minutes

Kaiten with yahoo: push five minutes

Ringer: vibrate

I think that's everything I have for battery use settings. I'm not going to be watching any videos or playing games while waiting for the battery to drain, just web browsing, facebook, twitter, and email.
[HTC EVO 3D] borgqueenx:
Yes, how long can you play angry birds inside the house with lets say 50% brightness? Straight gaming, gps and bluetooth off, nothing else off. Push, email accounts checking ect...all on.
[HTC EVO 3D] Joey121215:
Well I said three to five and low and behold three and a half hours. Here are the pics:

http://db.tt/QrZu4I'm

http://db.tt/o8ZaOag

http://db.tt/i3pVhQn

http://db.tt/BhlVhf6

So tell me is it just my usage and settings or a phone issue? In this time I was on the web, went on Speed x for give minutes, used front facing camera for visidon three times, IMed a little bit through go!chat, installed a working ooVoo but didn't madge any calls, received around five texts, made zero phone calls, downloaded and installed a few apps, ran chainfire benchmark and vellamo web test. I think that's it. . . Screen was turned on most of this time. Strong WiFi connection entire time

So any suggestions for a better battery life other than turning off radios?
[HTC EVO 3D] Drachen808:
It looks like you need to do a factory reset. Look at the "awake" bar in that third picture. Was your phone really awake that whole time? You may be having the wake lock bug.

If you go back a few pages in this thread, I was having really fast battery drain (after having great battery life). Someone suggested a factory reset and (just as an example) yesterday was my daughter's bday party. I took about 30 pics (about 5 3d) some with flash, some without. I was on wifi a lot and 3g a little. I had 1.25 hours of voice calls and just under 3 hours of display on time. I plugged my phone in last night after 14 hours and 15 mins with 18 percent left.
[HTC EVO 3D] ReinMaker:
This seems normal. According to those pics, you basically had your screen on the entire time (if you didn't try a hard reset then). I watched 3 25 min episodes, ran a few speed tests and just played with Sense and I got 3h screen time and 8h total time. Now if I had done all this continuously, I would still have 3h screen time and my total time would be 3h. Average with screen on here seems to be 3-5.
[HTC EVO 3D] Joey121215:
Yeah, my screen was pretty much turned on that entire time, I think there was maybe a ten-twenty minute period I had it off but that's all.

What I figured, just low battery life with my heavy use, going to have to buy these soon: http://cgi.ebay.com/3x-Galilio-2000...464244?pt=PDA_Accessories&hash=item3f0ba777f4

Thanks for the help guys
[HTC EVO 3D] spencer88:
Those batteries have had the sticker pulled on them, revealing 1000 mah underneath. I wouldn't buy them.
[HTC EVO 3D] supersund:
How do I do a factory reset? Does that mean that all my data gets erased?
[HTC EVO 3D] johnsongrantr:
I find if you turn your network to sprint only it vastly improves the battery life if you are in a sprint area. WiFi over 3g when avalible

And get juice defender 24 hours away from charger of medium useage is easy for me

sent from the moon
[HTC EVO 3D] jj14:
That depends on what you did in those 15 hours. Did you just leave the phone on your desk and not use it at all (no Emails, no texts, no facebook, no nuffin?) If so, no - that is not normal.

If you were playing plants vs zombies on your phone the entire duration (non-stop), that is not normal either, but don't tell anyone - people will be hounding you to sell that battery to them.

Jokes apart, it really does depend on what you use your phone for.
[HTC EVO 3D] Evil Bob:
Here are my stats. Keep in mind that this ran 3 days 5 hours before battery saver kicked in with a 15% threshold, so if you want to figure percentages it'll have to out of 77 hours. Fairly light use, 7-8 short phone calls, couple uses of the Google nav for less than 20 mins each, few dozen text messages, wifi and bluetooth off, GPS off when I'm not using nav.

Sadly the CCD of the Evo 4G kept over exposing on the first screenshot so you couldn't read the battery time off the charger on the main battery usage screen, so I went into the menu further and got the discharge cycle pic for you that has the clear total on it.

I uninstalled every Sprint app I could including Facebook, twitter, etc. I don't use any of it so don't need it installed. I have not temp rooted yet, no tweaks to the CPU, nothing, its stock minus the Sprint bloat.

Signal strength was pretty good overall, I did quite a bit of travel around the Twin Cities with it, only a couple times where I lost signal going through the tunnel just West of Minneapolis.
[HTC EVO 3D] Joey121215:
Okay, so I don't know if this is just coincidence or not, but I decided to condition my battery like on the old EVO. Let my battery die out and charged my phone turned off. Battery seems to be working better, been on ninety seven percent for about twenty minutes now.
[HTC EVO 3D] Evil Bob:
I also did this on launch day when I purchased it, ran the battery until it powered off, charged to full, the following day I charged it for several hours on USB at work, since then I've had outstanding battery life.
[HTC EVO 3D] iliapiano:
Can we all post the pictures please, my battery life was great 3 days ago and now it's getting worse? will probably get better tomorrow :-)
[HTC EVO 3D] bso44:
Can you remember any changes you made 3 days ago?
[HTC EVO 3D] -eVo-:
I'm at 18 hours, 54%	left and 56% is display, only 10% standby. This is crazy
[HTC EVO 3D] borgqueenx:
Yeah right so that makes more then 9 hours on the battery? Only possible with the extended cable, else its BS.
[HTC EVO 3D] iliapiano:
I think the main change is the amount of time I spend on my phone :-)
[HTC EVO 3D] Neo3D:
Check for wake locks, download CPU Spy from the market.
[HTC EVO 3D] yankeesamurai:
How to kill display batt useage while idle ....

In widgets install the wig called power , its got a brightness icon that will actually put the brightness at almost dark
[HTC EVO 3D] Neo3D:
If you know you have a CPU wake lock issue, go into your background services & processes:

App drawer > Menu > Remove App > Running

Here is a list of the ones that I have running that are OKAY to have:

-Settings

-DSPManger

-Music

-Google Voice

-Wallpaper Rotator

-Voicemail

-vDM Client

-Calendar

-Voice Search

-Google Services

-HTC Sense

-Maps

-HTC Hub Sync Provider

-CSPeopleSyncService

-FlexT9 Text Input

If it's not on the list, remove it and retest for wake lock until you find the offending app.

[HTC EVO 3D] Biofall:
Screen On isn't the highest, implying that aside from using the phone to make calls, you really don't have that high of usage.

I know this has been said a bunch in this thread in other ways, but I would like to point out threads/posts like the OP and several others in this thread are perfect examples of why we have a lot of noobs who spam the boards and freak out about their battery life. I would say that this is actually the reason why I created my battery life thread.

At any rate, let it be known that

Battery Life Like This is From a Device With Comparatively Low Usage, and Isn't Something That a Normal User Can Achieve

(referring to OP, not quoted pic, as much..)

More about that in my battery life thread, linked in my signature.
[HTC EVO 3D] Neo3D:
How did you get that screen?
[HTC EVO 3D] Neo3D:
Well, my "noob" friends' biggest complaint is that they hardly use their phones and it drains like no other. I don't know any who uses apps on their phone 8hrs / day. Most of us have jobs.
[HTC EVO 3D] jorts:
i use to get good battery life until i rooted and installed viperrom and a custom lock ring
[HTC EVO 3D] :
I get about 9-14 hours with 3+ hours of display time and the music app. The music app doesn't let the phone sleep either, its 100% wakelock. I'm a heavy user, its my androidian iPod.

Coffee and Hip-Hop!!!
[HTC EVO 3D] pkny:
After using the phone for a while it seems like the battery life for the 3D is really dependent on the signal strength.

The place i reside and work within the DC metro area has a very poor sprint signal and because of this i got about 8 to 10 hours of battery life with normal usage.

Now with me forcing roam I got about 15 hours of battery life. Even though it said i am roaming with 3g i am pretty sure i am getting data at the 1xrtt. So a nice steady signal with reduced data is giving great battery time.
[HTC EVO 3D] LostRib:
Are you running a custom ROM/Kernel?
[HTC EVO 3D] :
Synergy 2.3.4 nightly 458. Id let my phone charge. Use it for about 3 hours and let it run music while I sleep. I'll wake up at like 10%. I use 192-1188mhz on conservative. When it gets below 50% it sets to 192-648mhz on conservative. My brightness is all the way down also. Once aosp comes, I should get like 20+ hours heavy use with this setup.

Coffee and Hip-Hop!!!
[HTC EVO 3D] SayWhat10:
as mentioned, very odd that disply isnt the highest, but could be if you put phone to your ear and screen turns off

however, shows an uptime of 17hours,but phone has only been awake for a bit over 2 hours????? Meaning you only used for phone for about 2 hours or so, so yeh, u should have some battery left
[HTC EVO 3D] ScottSNX:
There's several threads here on extending battery life. Its possible to get a day's worth of battery even on moderate-heavy use.

I'm running ViperRom, I've enabled the Viper Control script, calibrated the battery correctly, and run Juice Defender and Tasker to control a lot of common tasks.

One thing I don't see mentioned is I also turn off Auto Rotate by default and only enable it in a few programs by default since I think it just wastes battery constantly "polling" the device. At least that's what I was told when I was on WinMo.

I also set the display brightness manually at 40% and have the Brightness Toggle widget on my homescreen. It basically toggles your phone from 0% to about 100% in 20% increments for when you go outside or are in your car.
[HTC EVO 3D] :
Auto Rotate? I wouldnt have thought of that. I also put my brightness down to the lowest. One reason I cant get higher than 14 hours is because music is ALWAYS playing. Thats why I need a 3400mah battery.

Coffee and Hip-Hop!!!
[HTC EVO 3D] SayWhat10:
how much juice would turning auto rotate off save?
[HTC EVO 3D] Biofall:
Instead of taking offense, read my post again and see how I wasn't using noob in a derogatory manner, and that i create threads dedicated to educating them. My point still stands, however, that threads like this give the wrong impression. By the way, in a full time student under a full advanced classified, so get off your high horse.

Sent from my beautiful Shooter on the XDA Premium App
[HTC EVO 3D] ScottSNX:
I have no idea on the auto-rotate thing on whether it saves battery juice, I'm no dev. But I remember from my WinMo days installing cabs from devs who recommended disabling it, or have it "poll" a lot less.

Maybe a dev can chime in on this because maybe Android handles it a lot better like it does everything else.

I'd love an app or widget that would let me go back and forth or "lock" my phone in landscape. Something I used to have on an old HP Ipaq back in 2005, seems like we go backwards sometimes.
[HTC EVO 3D] mancuk29:
quick question my new uk 3d evo is fab but im baffled my phone gets to 99% and stays there for ages its charging at 4.348v ... battery life seems what i exoected but is it normal to remain at 99% and red led for a long time ?
[HTC EVO 3D] justj:
yes, it usually take good 30-40 mins and if you install current widget or battery monitor you can see how many mA gets pump into your battery.
[HTC EVO 3D] gzbrambila:
Display 87% - that's the real killer for me.
[HTC EVO 3D] cobraboy85:
bought the seido 4,000 mah 2 days after i bought my phone.

i have my brightness fixed at about 30% manually, auto rotate off, heavy texter, play some games here and there, and browse around XDA from my phone and talk on the phone at least 1 hour a day while on my way to work (with the lady, we talk dirty)....

i dont even look at my battery icon, i charge my phone once every 2 days lol.
[HTC EVO 3D] libai8268:
Do you use your phone even for calls? Feels like you are just leaving it on the table.
[HTC EVO 3D] SayWhat10:
ha right!

Like i dont even have a home phone anymore, so i use my phone for business and social purposes. If people actually talk on the phone, I dont know why they are not draining battery.
