first drop task manager.. evolte has one built in sorta but android doesnt need it. i would drop both to be honest ive pounded mine in use and still havent gone into the yellow. first thin i would look at is cell signal.. update prl/profile etc. then second check your stats sending.. did you agree to send HTC/google data on usage? if so maybe thats it tho i doubt it
last check on apps youve installed maybe you got one thats going nuts.. take a screen shot of your power usage and post it too

Yeah, you don't need a task manager on android 2.2+
Also, does Evo LTE have the same charging circuitry the Evo 4g did, where if you pull it off the charger at 100%, it really could be anywhere from 90-100 and battery meter shows the true charge a couple minutes off charger ?

I'm with everyone else....I've been using the hell out of this thing and haven't made it even close to the yellow. I'm super impressed.

The problem is according to your username and icon you're on AT&T.
It takes a lot of juice for that Sprint phone to pick up an AT&T signal so it runs your battery down faster.

This is after the initial charge

I love how well this phone "sleeps." I left it unplugged during the night, and when I check it this morning it only had two little blips of Awake time.

I'm not getting more than 10 to 12 hours out of a charge with light use. I have got to figure this out.
Edit: battery use says 68% is the display. Maybe its the newness still.

Make sure LTE is off if you're not in an LTE area. settings, mobile network, network mode, cdma only.

I'm having the same problems. I am on it constantly, but no more than my 3d and it's not getting any better battery life at all. From 8-10 hours.

i dont think it makes a difference on this phone. on the OG yes.. if you turned on wimax even in a wimax area it sucked power. my understanding is the wimax used a separate chip and thus drew more power where as LTE is built in and uses no real extra power

Ive fully charged the phone twice so far and both times Ive gotten around 23hours of use. Thats with moderate usage of texts, facebook, internet, and the addicting yet battery killing game Crime City. I bet if I didnt play that game I could easily get a day and a half.
For reference, my OG evo battery would be dead in about 6 hours doing the same exact stuff. Granted, I was on the original 2 year old battery.

I've used the crap out of my phone the last two days and my phone has lasted all day and then some. Yesterday I was in an area that had no service and I was taking pictures all day and my battery was at 40 percent after 15 hours of heavy use.

My battery is amazing I still have 70% after 8 hrs. Try downloading bad ass battery monitor it's great. I also use battery level to keep my screen at 25% and not auto brightness or nothing. The other saving tips could be obvious, no vibration on anything, wifi if possible, not many widgets running, syncing. I always turn my 3G/mobile network off when I leave the house I just turn it on when I'm checking FB, Twitter stuff like that

Battery Life not so bad in non-4G area

I bought myself and my wife a TB on launch day (yes I love being a guinea pig), and there are no 4G covered areas anywhere near here (all 3G). Both phones were properly charged after being activated and before being tested. My own phone was unplugged yesterday morning when I arrived at work at around 7:30 am and it finally died at midnight with light to moderate use (some phone calls, texting, web surfing, downloading apps, one hour of listening to music with double twist app and jogging with cardio trainer app)., Today my phone has been unplugged for five and a half hours and it's down to 80%. My wife is getting about the same battery life from her TB.
We knew from earlier reports that this phone lasted only about four hours running 4G LTE, and even WiMax running on Evo gave it terrible battery life, so I'm not entirely surprised that there are are still problems with this phone regarding battery life and 4G. I am almost relieved that I don't live in an area that has 4G at the moment.
Just to clear the air, I'm hoping that other TB owners who do not live in a 4G area will share their experiences with battery life so we know that this is mainly a 4G issue and not entirely a TB issue, and hopefully if that is the case, we can get a push for a 4G toggle until this issue is resolved.
Same here
I am getting better battery life out of this phone than I was on my Eris on GSB 2.0. I am very surprised. I use WiFi at home and that seems to really help but out in 3g....it really is quite good. I haven't had it in a 4g area so I can't compare but I have no complaints.
Even in a 4G area you can turn off LTE and get better battery life. I made a shortcut to the phone setting using anycut.apk to make a short cut to phone info. Got this from another thread on the forum. Works great.
My battery lasted 12 hours yesterday with what I would consider heavy use. An hour of gaming, 2 hours of pandora, about an hour of voice calls and checking facebook throughout the day. I'm very pleased with battery life. I was on wifi most of that time though and there is no 4g in my area.

Not very sure how to do that..can you explain how i can do this ..Thanks
Happy with battery life so far
So far my experience has been quite favorable. I have been using my phone quite a bit, navigator, text, browsing, games, fm radio (we really like that) and frankly the gloom and doom reports fortunately haven't come true for me. I am easily seeing 9+ hours.
I have had a couple of nasty freeze-ups while on the phone. The first one sent the phone on its own reboot, the second required the battery to be pulled (good night that is a challenge) since the screen and the buttons became unresponsive. I will have to watch that - a phone has to work as a phone or well, it is a mini tablet instead of a phone.
first full charge last night, off the charging this morning, after 10 hours of uptime unplugged, which included a few phone calls, facebooking, playing around for about 30-45 mins on games, i was still at 81%.
This is far better battery life than my evo ever was(until i rooted it and had CM7, was getting 3 days a charge then.) And if it says anything, it isn't rooted yet(working on that now) so I am very happy and impressed with the phone so far...
and as for a previous post. I was unaware that you could turn off 4G/LTE at all. My understanding was it was always on no matter what.
Agreed. When the TB is not switching from 3g to 4g. Battery is good

He is running a custom rom that likely dramatically governs the processor and other power factors. It was the primary reason I rooted my Incredible as the custom kernel I got had me go from 10% at the end of a 16 hr day in standby to about 80% remaining. So I could totally see 3days of light to no use from the EVO with a custom ROM.

yeah that is pretty much it.
CM7 is very very light, and also had SetCPU to down clock the processor to 245Mhz anytime the screen was off. It was also on the stock battery too. I have no idea what I could have gotten with an extended battery. That 3 days wasn't practical, but I made it happen non the less to shove it in a friend of mines face who kept his iPhone 4. I had an iPhone 4 and left it for the Evo, and he got mad about it.

if you look at the bottom you can see the screen was very seldom on, I always had wifi off, gps off, and 4G off. Phone was still at like 9% i think to when I took that screen shot. I could have gone longer but my phone is my alarm clock and I had to be up the next morning and needed to go to bed. Stupid jobs and having to work. haha.
After a couple of charge cycles I must say that I am very satisfied with the battery life on my Thunderbolt. I was at work the other day for 12 hours and the phone was at 35 percent when I left.
I agree. The Evo has terrible battery life out of the box but with CM7 and proper tweaks for it's settings, you can get pretty good battery life, even using a stock battery.
Considering that the battery for TB is a lot better out of the box than the Evo, at least for those in non-4G areas, I can only imagine how great it will be running CM7

the only thing that bothers me about it, and someone please chime in if I have no idea what I am talking about, is after pulling up quadrant and just looking at the info for my system, it showed my processor on my TB as running at 245Mhz at that moment, and capable of running at 1024Mhz.
I could be wrong but I thought the evo ran at 998Mhz right out the box and didn't change clock speeds.
So if this is the reason why battery life has been so much better out of the box, hopefully we can still make a gigantic improvement.

90% battery after 12.5hrs!
I keep all the radios on (4G, 3G, wifi, bluetooth, gps) and brightness set to auto.
...
I couldn't do a screen shot from the phone cuz no root yet
Manl, that's insane how efficient the new dual cores are!
Only if you dont use the phone. Hence your display percentage so low. Mine went about 12.5 hours on battery with the display on for 3h total
That is one thing that I don't understand about this phone. Sometimes, i'll pull it off the charger and not touch it for 12 hours and the battery will still be in the 90's like you see above. Other times, i'll pull it off the charger and not touch it and it will just slowly drain and be into the 60's or 70's after 12 hours (and it's still sleeping). Don't get it. Signal is always good here too.
I get about 3 hours of battery, and I don't even use it for calls really.

he was talking about the indicator in the top left corner.

After 7 or 8 hours I hit about 20-25%. With Juice Defender Ultimate I get about an hour more of battery. But thats still not enough for me hah.

I know why my battery life sucks. I use it way too much... Lol... Underclocking to 685mhz works pretty well and the phone isn't all that laggy. It is definitely bearable.
Sent from my PG86100 using XDA App
The only days I get battery life anywhere close to that are the days that I am super busy and just don't touch my phone, except to answer a call or text. Days where I have too much time, I'll constantly be on my phone playing games, researching things, youtubing stuff, listening to music, and on those days I'll get 9-12 hours, which is still good in my book. It'll easily go over a day with very light usage. I can leave it off the charger at 100% over night, and it'll be at 97% or so when I wake up, but as soon as I get on that XDA app for 20 minutes I'll be down to 75%, lol. It's ironic that the XDA app is such a major battery drain, and that is one of the apps that I use the most.

If you get '3 hours of battery and don't use it for calls' then you either have a defective phone or lying. I do vallet and play Video's all day work 5PM-4AM and I never have to charge my phone although close to dead by the time I leave. 3 hours? I don't think so.
Fact 1: 9 times out of 10, if you don't use your phone at all, the battery will barely drain.
Fact 2: If you were to actually pick up and use the phone, you wouldn't get nearly as long out of the battery.
That's something that baffles me about people and keeping track of battery usage. They leave their phone sitting there over night and all day without touching it, and then have kittens when the battery percentage barely goes down. Well.. newsflash, that will happen if you don't use the phone at all. I guarantee that if you were to use the phone for any length of time the battery would drain a lot faster than that. So that isn't an accurate indicator of the phone's battery life.

Faulty battery?

Hi guys,
I bought EVO 3d about 4 days ago and I'm really not sure if I have faulty battery or not.
I had wildfire,so maybe I'm little bit spoiled with its good battery life..
For example I'm now browsing and using tapatalk only, with brightness on lowest setting (even capacitive buttons are turned off via screen filter) and after 1,5 hour phone takes 20% of battery!!
Sys info showing that 90% is consumed by display.
Is it normal or not?
It doesn't look like ok to me..:/
I can still return EVO and get desire s instead,if it doesn't have battery life issues...
Thnx for replies
Sent from my HTC EVO 3D using Tapatalk
So after this day I have 17 hours without charging, around 5 hours of using dispaly (4h on lowest bright. set. and 1 hour of 60%) this drains 70% of all consumed power
Rest is wifi,some cpu time etc..
Is it ok or not? I had wildfire and battery life with surfing and reading books was unstoppable..
I can also switch this phone for Desire S, but I have no idea how long battery life it has..
Sent from my HTC EVO 3D using Tapatalk
Get another battery. Also are you rooted and overclocked?
no, everything is stock, unless bunch of apps.. but ia I said, everything is consumed by lcd.. another battery on 4 days old phone sounds really bad [and hurt my wallet ]
how long you can go with yours ? how many hours can yours display handle on one charge ?
I really needsone help here. When I charge my batt. fully (green light) put out charger and turn it off and on again I can charge it again for really long time (for example 30+min) and I can do this multiple times.. charging time is shorter each time..
I tried this procedure twice and seems to be same..
I need some battery reset or something, I read some topics about it,but I'm not sure what to do. And i don't have rooted phone.
What should I do in this situation, without rooting device? (which I have never done before and I'm afraid of bricking my phone )

I get about 14 hours on a full charge man if I do lil to nothing such as text some youtube and xda and what not I can go a day without charging.
Anyways haven't had any issues.
I can get all day with small use too, but I wanted to know the real number of hours with turned on display, the value from default battry usage application which counts time for display separately.
I have had the same issues as you with battery, I'm rooted and on a custom ROM (steel rom) and battery life has been much better, also they sent an ota update by HTC that is supposedly going to make battery life better

oh.. maybe its not battery problem but it's standar behavior :/ thats why I asked if is there huge difference between evo and desire S, which I can get insted of evo,[for the same price] I know desire is worse in many aspects [and dispay is really small, comapre to evo] but what is the point of having superb phone, when I have to switch off every auto function and half of widgets only to have one day of use because of crappy batery life...??
I'll gladly have worse piece of hardware [which is not that much regards to normal use - web/mail/phone] if it can stay alive twice as long. But as I said I have no idea how are other smart phones capable to stay alive these days..
I had only wildfire, and it was good.

I spent a lot of my time outside this weekend so I would say my phone usage was "lite" but I got over 36 hours and still had 30% left. Today I've been on it all day and im at 55% and I've been off the charger for 10 hours. The battery is a LOT better than my OG Evo but I'm SERIOUSLY impressed with this phones ability to "sleep"
I'm reading 59% after 7 hours and my first day of usage. My EVO 4G would have kicked the bucket hours ago. Though I haven't ran any hogging apps today, I have had my phone on a lot.

Mine seems to wear down faster than it used to (not nearly as fast as the BAMF leak). I wouldn't call it twice as fast, just faster. What I have noticed is it also charges quite a bit faster than it used to. I like the faster battery charge, unless it's just giving us a false reading when it's not really full, which might also explain the quicker wear down.
I use the extended battery so wear down is less of an issue for me.
Make sure you check the battery menu under system settings. The first time for me the light turned green but under that menu it said it was still at 78 pct

I'm running liquid's ics (jmod) public beta 2 with the combo radio and my battery life is awesome. I haven't run it down yet, but it's easily lasting twice as long as my old gingerbread rom which could go a day without a charge and light use. When it's idling in ICS, the battery life seems to hardly drop at all.
I think I figured out why my battery wears down quicker. I've always kept LTE turned off. It's been on lately, so that would account for my additional battery drain.
I set battery percentage to show up on my lock screen, so it's easy to see the battery percent without going through the menu.
I got over 13 hrs. today. Most of the day I put the phone in CDMA evdo auto which helped a lot. I work in a lot of areas that don't get 4g so it drains my battery super fast searching for a signal all day.

Mine is not to bad. Not as good as it was on Thundershed but that could be cause I'm on it more playing. Also still getting my screen down to levels I like.
Time will tell for me.
Really think that reflashing radio fixed me. Did that, reboot a couple times and...

I also noticed that the lower menu bar (home - menu - back - search bar) stays backlit all the time. Including when I push the button to turn the screen off.
I don't know if I accidentally did that while playing with all the settings, or if everyone else's is doing that too. Either way, I'm pretty sure that will affect my battery life as well.
Edit: A reboot seems to have cured my backlight issue.
My back light is off permanently for some reason

My battery life has been horrible for months. I can leave my phone plugged in all night and it will only charge to 52%. If I turn it off and charge it for a couple hours it'll read 72%. That is as high as I can get it to go. No fully charged. For about the last 3 weeks it'll drain in about 2 hours. I've been running the new radio recently and still see no change. I even turn off LTE and still don't see much of a difference. Any suggestions would be appreciated.
Drain it and charge 8 hours with it off then reset battery memory.

I would say bad battery maybe? Have you tried a different one and see if it reads the same?

You can have half of mine.
My backlight seems to be back to always on. A reboot won't cure it this time.
