Dunno how you guys are getting such good battery life. I have done the calibration thing (using the phone till it shut off, than charging out 100%), and the most I got was around 8.2 hours. In this 8.2 hours, I took about 10 3d photos, a 15 second video, and used the browser on 3g for about 4 hours continuously. At the end, the battery app showed the screen used about 85% of the battery (had it set at 25%-35% brightness, ie. 1 bar on the brightness app). I didn't have any push or auto update running in the back ground (face book, twitter, gmail), those were updated manually. Also does your guys battery get really warm (105 degrees) sometimes during use?

Or this is good battery life?
[HTC EVO 3D] RedWingsFan:
Using the broswer on 3G for 4 hours straight will hit the battery hard.

Can any one look to see I'd they are getting a wake lock while charging . You can check be going to settings»about phone» battery and looking at the awake time vs time since boot . I am having a wake lock when I am charging from ac and usb it might just be my phone though

Thanks

This is crazy. People will do anything these days. Look its simple.

For a battery that last long in life. That means the battery holds the same level of charge. For its life.

Plug in around 15-20%

Unplug when your phone tells you too.

Where is this juicy info coming from?

The guy who designed the lithium cells.

An article recently done where they just flat out ask the guy who made them.

His answer?

For best life and performance.

Charge at 15 to 20%.

Unplug when full. Don't over charge.

Google it.

Coming from an EVO 4G, I am seriously impressed. My EVO 4G would run out of juice before the end of the day, even with light usage. I unplugged my EVO 3D on Saturday morning and played with Youtube in 3D for a few hours on Sat and Sun. Sunday night, I plugged it in with 30% juice left.

My first experience with the battery life is a good one. I used it quite a bit, taking 3D pics, video, texting and placed a few calls. By the end of the day, I was still in the green!!! I cannot even compare it to the orig Evo.
[HTC EVO 3D] Zorachus:
I purposely left the phone unplugged last night, just to see how bad the battery drain would be overnight with no use. I left the on desk at midnight with 93% battery life, and picked it up at 7:30am and it was at 88%. Only lost 5% over approx 8 hours, with zero use, except the fetching of e-mails, and radios still being on for any phone calls or texts.
[HTC EVO 3D] pain-is-free:
well with three E-mails HTC hub and all the sprint bloatware running, and heavy use on Sunday, i literly got the whole day out of the phone. with my evo i would need to plung in mid day atleat twice. so for me the battery is awaome. how ever saying that, it did take a while for the green lignt to come on the first time I charged the device.

im charging my phone and intead of the battery going up i feel like is discharging it :(

I've kept my internet off till I've needed it. With about 5 phone calls, I've took a couple of pics and a coupe of minutes worth the 3d videos, a couple of rounds of the spiderman game, a few texts and about 2 hours on facebook, twitter and reading the news on the internet, I'm at 45% after 20 hours. Now about 7 of those hours were last night while I slept, but it was still on and unplugged from the charger.

I did the same with my old evo and 20 hours was about max. I think the battery is great in my opinion.

Just an FYI I've had my phone since last Wednesday, and today being Monday I'm REALLY starting to notice that my battery life is getting A LOT better!! I come to work at 9 pm and last week by 11 pm I'd have about 80% battery left. Using the phone just as much tonight at 11pm I have 96%!! I guess it really is true that u need to condition the battery and it gets better after a week or two.

Mind you I have all sync off. No gps. No blue tooth.

I've gone through and stopped manuallyand programs not needed.

I also removed bloat.

Also I don't have any accounts synchronized I put all on manual and also took auto brightness off maybe its my phone idk
[HTC EVO 3D] mikeyxda:
How? And what bloat did you remove that affects battery? Other threads say the bloat isn't really removed. Battery life for me is worse than my Evo 4G. I have sync, bluetooth, and GPS all turned off and I'm still only getting maybe 12 hours out of the battery: and that's with it in my pocket all but maybe 30 minutes a day.

[HTC EVO 3D] dcyouknow:
Another day of interesting stats for me. I normally place my phone on airplane mode while at work, since I typically spend 8 hours in roaming. With the OG Evo, if I left it on all day, by the end of an 8 hour shift I would be down to 70-75%. Today, I decided to leave my 3D on to see how bad roaming would affect battery, and at the end of a 10 hour shift, it drained to 88%. This included sending quite a few text messages and emails and checking Facebook for about 10 minutes. I'd say thats a pretty big improvement.

Quick question - to conserve battery, is it better to leave wifi on or off?

My initial thought was that turning it on will consume more power.... but given that a weak 3G signal will drain battery at a fast rate I was wondering whether it would be better to just leave it wifi on while I am home. Thanks for any responses.
[HTC EVO 3D] hockeyfamily737:
I usually leave my WiFi in at home....but then again I'm a 3rd shifter & sleep in my basement where there is no 3g. Try it & see if it works for you.....the WiFi that is, not sleeping in the basement :)

[HTC EVO 3D] Zorachus:
Yes the battery life is better than the EVO 4G, but that's like comparing a head shot to a chest shot, they are both bad, just one worse than the other.

I use my phone, as god forbid, an actual phone calling device, and with the absolute **** tastic 3G Sprint is having around Chicago lately, the drain is bad because of such a weak signal.

Even my WiFi disconnects every time. Never did that on my ogEVO.

[HTC EVO 3D] Wingilot:
Going on 12.5 hrs with about 30% battery life left.

Placed a few phone calls, a bunch of texts, turned off data most of the day aside from breaks at work, used quite a bit of 4g at lunch, other than that the occassional 3d to show off to co- workers.

Given this my first smartphone I don't have much to base it off, but the battery has done just fine by my expectations.

On a side note,

Just wanted to say hello. I have been following this community for a while now but waited till I got an android to jump in. So again, hello, thanks, and here is to the eventual root. Cheers.

[HTC EVO 3D] Evil Bob:
I got my 3vo last Friday (June 24th) when the retail stores were able to sell them. I ran all the OTAs that were available since then (yeah, I'm holding HTC to their word that they're going to give us root, so I updated to fix bugs, etc) so its up to date.

I charged the phone to full on my laptop (was using 4g via USB tether to test our website externally) and thought to myself when I unplugged it, "now that I've had this for a few days, I may as well see how long the battery will go until it asks me to recharge" so I didn't plug it in for the last couple of nights, I normally charge it between midnight and 6am.

The last two days have been fairly light use, I think I took a total of 3 calls, all very short, wifi off except for a couple minutes here and there when I check the market to get it to refresh icons a bit faster then 3G can, 4G off the whole time, and what looks like around 50 text messages over the last two days from my wife and kids and a couple folks at work.

I dug around frantically for a screen shot app on the market as the only current screen shot capability requires you to plug it in, which starts charging and nukes the battery stats. Tried getting a phone from a co-worker to take a shot but only blackberries were available and their crappy camera is difficult to read. But here are the details from the battery section:

Uptime: 78 hours, 22 minutes

Time since unplugged: 50 hours, 17 minutes

And the "you might want to plug this in" battery saver (set to 15% threashold) red light just now came on.

50 hours off the stock battery with the stock ROM fully updated with light use totally blows away anything my Evo 4G could do even with custom ROMS/kernels and SetCPU, best I could get out of my 4G running Ava's Z3 was 26 hours before battery saver kicked it at 15%.

Once we get root, nuke the bloat, and a few solid custom ROMs for this, I can see 60 to 80 hours of battery life on light use being the norm for the 3vo.

HTC did an amazing job with this one!

I got sprint to send me a new evo 3d.... When I receive it should I charge it first b4 turning it on and using it? Or should I use it and drain it all the way then fully charge it?
[HTC EVO 3D] nhutpham:
I wasn't able to charge my phone fully the first day, and it crapped out on me because I didn't make it home that night. Next day after charging almost full battery life was about the same as the OG evo, not quite a full day. Third day my phone died in about 7 hours, steady drain from full to dead on the battery graph.

I did the battery procedure they told us for the first EVO, full charge overnight, one hour charge with the phone off, 1 hour charge with the phone on, and my battery life has been really good today, hardly goes down without use.
[HTC EVO 3D] jaypeezee:
Obviously not scientific buy I seem to be noticing decent battery usage.

On Wifi with moderate/light-heavy (uhhh) I'm getting 15-16 hrs roughly with majority of the time actually connected to a wifi network.

On 3G with same usage, I'm seeing 8-10 hrs.

I don't stream videos or watch youtube however I do snap photos, browse web (lots of it), tapatalk, live holdem, and use slacker quite extensively.

Overall I'm pretty happy with the battery life I'm getting.

Happy Battery

I've been surprisingly please with battery life. I usually plug it in a charger before needed out of habit. So I decided to just let it run yesterday to see how long it would last. I had wifi on,gps on,live wall paper on, made more calls than usual, did some Facebook, email and net surfing. Also used a walking app Runkeeper that gives audio cues of time and distance for a 45 min walk. I do live in 3g land so it would not be the same with 4g.

So I turned the phone on at 6:30 am and at 9:30 pm the battery light turned yellow. Did not get a low battery warning, turned the phone off around 10:15 for the night.

That's 15 hours!
[HTC EVO 3D] tablo:
Guys, I'm at 1d 1h 51m and still 30% battery left. I used it for voice recog, GPS navigation, browsing, a few calls, text etc. What I would consider moderately heavy usage. This battery is no joke.
[HTC EVO 3D] mikeyxda:
I'm finding that I get very good battery life until I go to an area where it has to search (hard) to find a signal, particularly a 3G signal. At that point, it does the same thing that the old Evo 4G always did: when it's searching for a signal in a fringe area, it absolutely defiles and then teabags the battery at over 1 percent per minute. I really wish they'd fix that.

Mike
[HTC EVO 3D] mr.orange303:
There is an efficiency setting that allows it to only search for signal while awake. In battery in the settings I believe.

Unless I'm mistaken.
[HTC EVO 3D] mikeyxda:
Thanks. Has some unwanted side effects though. It turns down screen brightness (all the time) and if I use that, I can't reliably get email messages from things like security cameras. They really need to fix this right so you don't have to babysit the phone to remain "connected to the net". If it's struggling to get a signal, it shouldn't just sit there drawing over an amp of current continuously. When it loses 3G, it could simply retry every 2 minutes. That way it's only using that kind of current draw for a few seconds out of every 120 seconds. As it stands, if you need to be able to receive emails reliably/quickly you either have to risk huge current draw in fringe areas or you have to babysit the phone all the time.

[HTC EVO 3D] EniGmA1987:
For some reason I get 1-2 bars almost everywhere, except at home. My battery life drains fairly quickly because of this. If I am at home it lasts a long time, but anywhere else and my battery will only last 4-5 hours with very light usage
[HTC EVO 3D] LostRib:
can people getting really good battery post their settings? The other day I got about 13 h, with about 3 hours of the display on. I left my phone on while i slept, with background data and auto sync on for a while
[HTC EVO 3D] mikeyxda:
See, that's what happens to me too. I get great battery life at home because the phone has WiFi there and when WiFi is available, it turns 3G (mobile data) off. Then I go out to a restaurant somewhere and if I happen to be sitting in a location that has bad/no signal, by the time I get up from the table an hour later, my phone might have dropped 40% or more battery just hunting for a signal (or trying to keep a weak signal).

What I'm proposing is that when the software sees a couple minutes of high-drain hunting, it stops hunting continuously and only checks/syncs once every few minutes until the signal strength comes back (it can test signal strength on one of the periodic checks). Then it toggles back to normal. That simple change in logic would save us all a lot of battery troubles!

Mike
[HTC EVO 3D] RedWingsFan:
I've read in other threads that people are draining their batteries until it dies, turning them off, and then charging via USB/Computer. This results in better battery life.

What is the science behind this? Or is this simply a coincidence?
[HTC EVO 3D] lmbebo:
http://xdaforums.com/wiki/index.php?title=Battery_Calibration

I believe that is what you are referring too. I did that the other day. Really haven't noticed any change in battery life. Somedays at work I'm capable of having it charge all day. Other times I'm in a dead area where the battery just gets eaten up. I usually turned on plane mode.

The only time where I've been away from a plug, the battery life wasn't great. I think I was out from 9:30 am till 6 pm. Came home with the battery near 15%. This was with me trying to avoid using the phone.

It lasted longer than I expected. I tried out a droid incredible about a year ago when it came out. I had returned it after a week because the battery died on me in 4 hours of use. Thought it was ridiculous to have a phone like that die so quickly. Thought it was a software issue. Reset the phone so many times....

[HTC EVO 3D] Wekko306:
Could you guys also include some information on what actually drains the battery? Saying light/medium/heavy use doesn't tell me all that much without any real numbers included.

I'm mostly interested in how much screen on time (at a specific brightness setting) you can get out of this phone.

My Desire HD can get about 4 hours of screen on time at 25% brightness a day before its dead.
[HTC EVO 3D] mr.orange303:
Screen on auto bright . Efficiency checked in power settings.

Roughly 2-3 hrs internet. Only about 30 - 40 minutes of calls. Maybe 15 text. 5 3d pics. Several 2d pics.

Maybe 4 hrs on xda app.

General use like changing wallpapers refreshing friends widget etc.

Thanks! Definitely looks like an upgrade coming from a Desire HD then.
[HTC EVO 3D] brienzee:
I've been getting decent battery life. I have a hard time telling though, because I keep my phone off and on the charger all the time. That's always been a habit of mine, so I haven't got much real world testing. Except I know it lasts a lot longer than my wife's Evo 4g, which dies almost instantly after she gets off work, with barely any use.

I did have an issue where I put it power button down in my pocket while I was at work. Completely dead after 3 hours, and strangely a bunch of settings were changed and turned on and off. That button is super sensitive. I'm going to get a case so that doesn't happen.
[HTC EVO 3D] rank78:
Maybe I just haven't found the answer, but has anyone else had the problem with the phone being dead the next day even though it had power when turning it off? I've been getting great battery life but last night when powering down I had 30-something percent only to not be able to turn it on this morning. I plugged it in via usb to charge for 10 minutes and after turning on it said 31, so it wasn't dead. Same thing happened last time I needed to charge but I don't recall how much power I had.

I'm using batterminder to determine percentage, and while I'm wondering if the levels are being misreported the first occurrence happened before batterminder and the system-battery level showed 1/4 charge left.

Any ideas?

[HTC EVO 3D] LostRib:
Does taking it on and off the battery without fully charging cause any damage?
[HTC EVO 3D] Gene_Bailey:
I had a seperate issue that when reading this problem makes me think they are related..

Has anyone let the phone die yet? Like no more juice no more life phone is kaput dead dead? The reason why I ask is because all three times its happened to me, when I plug it back in it immediately goes on and to the home page like it had been on sleep mode. I don't understand this behavior. I think its HTC's fastboot keeping the phone on when its off.. but if thats the case then how did it maintain the charge when it died???

I think fastboot kept your phone *on* overnight even though you had turned it off. I could be wrong though.
[HTC EVO 3D] brienzee:
I'm pretty sure that has no effect on most current batteries.
