Story @ Tech Crunch.. QUESTION FOR CURRENT EVO USERS

In the story he states that the batter would last four hours? any truth to this? he also explained that there is lag in the sense?
http://techcrunch.com/2010/05/29/htc-evo-4g/

Maybe 4 hours of non-stop web browsing with the brightness all the way up while on 4G. Also, I've never had any lag with Sense.

The battery is is very poor. I'm not exactly sure why that's the case since the EVO doesn't report the screen as a large draw. For example, I unplug my EVO, connect my Bluetooth headset and listen to a podcast for 10 minutes. That drains the battery to 92% from a full charge.
You will most likely have to carry a spare battery to get through the day, with light usage.
I'm hoping its an optimization issue and they can fix the battery issue with an update. Fingers crossed.

hmm, alright i mean this is big for a person who is out 24-7. (arnt we all) i wonder if it has to do with anything similar to what the hero had when it was released.

My battery life is not perfect. But people always have this problem. I was a G1 owner and everyone complained about the battery life when it first came out. And then slowly after a mont or two everybody stopped...why? Because the battery life got better with time. From 5 hours or so to 9 or 10 hours.
Then I went to an HD2. The first week I was so scared I had made a huge mistake because the battery would last about 4 or 5 hours. After I did as suggested and let the battery completely burn out and then completely recharge for about three cycles, the HD2 had the best battery I had ever seen. i could use it for 2 days and have 60% left.
Now I have an Evo. And the first stay (with constant use) it died after about 4.5 hours. But I am going through the process of draining and then FULL recharge of 6-8 hours and I'm sure it will be fine.
People think they plug the phone in an hour or two and it says 100% and they have charged it. My opinion is that it takes the battery a while to know what 100% and 0% are on any given battery. After it cycles through a few times it will actually have a true accounting of the battery life, power consumption.
That is all my opinion and experience. I am hoping the EVO has a similar battery life to the HD2. That would be perfect for me.
EDIT: And as for lag....the guy is obviously on crack and just saying stuff to say stuff. I doubt he even has an EVO. He's reading about Sense Lag on the HD2 which there was some) and passing that information on. Anyone who actually HAS an evo have any lag? I think not.
And if he thinks an iPhone 3GS in ANY way blows the EVO out of the water...he is obviously lying. I mean based on feature set alone. There is no way the iphone can browse as fast (4G...hello), operate as fast (gee isn't that processor almost twice as fast), take better pictures? No. Have a front facing cam? No. Oh yeah...that screen size on the iPhone sure is better than the EVO. WTF?

I understand what you are saying. That was the only reason i am worried about buying an EVO. This author must have had all the applications syncing every 15 minutes. I have an apple itouch not sure how close the phone and this thing is but I like it. It is smooth and quick. (buts its not a phone). When it comes to android... Its about the experience that comes with it.
But this guy is positively being paid off haha

With light usage I had 36% remaining after 14 hours the other day. I think you just need to give the battery time to get adjusted. However, I have noticed that it seems to drain faster from 100-80% than it does from 80-50%.

Well I actually just recently noticed the same about my iPhone 3G. The first 10-15% go really fast.

My evo seems to do pretty good with the battery I can go the whole day without needing a charge but I do charge it when I get home. When I'm using it for games all day it drains pretty quick but at those time I plug it in... I don't know what they expect when your rocking a 1ghz processor, a 4.3 inch screen, and about every type of network connection you can fit in a phone... as far as lag goes on this phone I notice very little mainly when I'm installing like 3 or 4 apps at once... compared to my hero this thing is a rocket! And once Android 2.2 is put on here this thing will be smoking.

My Evo lasts for 8-9 hours. That's 70% idle with screen off. Cell Standby at 40+% is killing my battery.
My motorola droid in the same time still has over 50% charge. There's no question that the Evo is a battery drainer for whatever reason.

hate to say it, but once a fan boy always a fan boy. I used to have a win-mo device (touch pro) and i like it, then i moved up (should i say downgraded) to the instinct- worst decision ever. than i used the android platform on my hero. I'd have to say its leaps and bounds easier than win-mo.. My brother has an iPhone which i always play with when he comes over, and i think its a really easy interface to play with.. thats all. The speeds at which apps were open weren't any better than my hero. I also opened up maps on his phone and mine, and my location was dead on with the hero, the iPhone was 100meters. LOL.
But everyone needs to try other stuff out and make there own decisions, dont let someone who is obviously a fan boy tell you whats good and bad.

thats ur prob ur using bluetooth it will use more battery and then ur playing the podcast at the same time any phone u do that on u will use more battery

the battery technology is a few years old. the cpu is 1ghz.. the phone is sniffing 3g/4g/wifi/bt plus the shiny screen and backlight all use power. the battery technology being used in this state of the art phone is not advancing as fast as the phones are...
the reason the top ~10% of the charge goes so quickly is due to the you taking the phone off charge.. the cells in Li-ION batteries are not created equal. some cells will get a stronger/longer charge than other cells. once you take the battery off charge, the cells that are stronger in charge than the others will feed that extra charge to those other cells, so your battery charge will fall down to around 90 or so pretty quickly out the gate.. from there the cells are all stable and equally charged and stay at a constant discharge rate for about ~87% to about ~55%.
once the charge falls below 55% the cells really start to lose their charge and the battery curve drops drastically.
when you "top off" the phone for , say, 30 minutes or so and you take it off charge and you see 100%. do understand that one or two cells have a fuller (my word) charge than others.. once the cells equalize, then you will see the tru charge (which will be much much less than 100%)...

I'll post my findings here although probably no one will believe me. I'm not a fanboi since i've phones on three carriers.
My EVO will lose 2% per hour sitting idle which is fantastic. My HD2 loses approx. the same amount, maybe a little less.
I've found the EVO to be no more power hungry than any "superphone" i've used including the iphone 3gs.

signal strength also plays a part
one thought based on my experience with a palm pre and htc hero: signal strength.
My office has very low signal strength (1 bar or less). The battery seems to drain quite fast here. If I'm somewhere else with good signal, my battery lasts much longer. Same battery drain if you're going in and out of evdo / 1Rxx.
Sean

My battery life is like all the other phones i had lately (see my sig).
No more, no less.

I have to say my battery is getting better with going through a couple full charges, as for lag nope none not here

“Phone idle,” and “Android system” that eat up over 75% of the life.

LMAO, the fact that he wrote that puts severe doubt in his skills to review an android phone.

I can't believe this thread is going on seeing as that's an Apple Fanboy site. Will say anything to make his Iphone sound like the best thing ever. He lost all credibility when he said the Nexus One and Incredible were better phones.

the battery in the EVO (and pretty much every phone evar) is a single cell battery.

Impressive battery life

I have been very impressed with the battery life I've been getting on my Nexus. the talk time has been much higher than any phone I've owned. Here are a few screenshots of my battery life. These two days are pretty much my normal day (lol yeah I talk a lot on the phone).
The first post will be the day that about 50% of the time I was on wifi.
The 2nd post will be screenshots from a day of being connected to hsdpa for the entire day (no wifi at all).
My setup: I use push email, facebook sync, auto brightness, gps on, bluetooth on.
Also, when the phone first came I charged it completely then ran the battery down until the phone shut off. I then charged it completely without removing it from the charger.
Below is the day where I was connected to wifi about half the time:

These screenshots show the next day where I used no wifi at all and was connected to hsdpa the entire time.

I have had mine for 2 days, and I have to say it seems to have pretty good life as well, compared to my Atrix and Note. After reading about all the gripes here,
I was expecting the worst. This battery will more than get me through everything I need to do with it in my day, but I suppose it all depends on what you do with the phone.

Coming from a G2x with a terrible 10 hour battery life, anything I get out of this is freaking fantastic compared to it! I Just wish the devs start getting out some UVed kernels so I can make it longer through the day! I consider myself a heavy user/texter (girlfriend ) and so I'd like to get through the whole day (~18 hours) without a charge I must say, I got to 16 hours yesterday and I was really pleased with that, never had a stock rom last so long without any tweeks!

this is my battery life after first day ....
Not to shabby haha

mysterioustko: I think you're usage is a bit different to the average user. With all that talk time you're using the screen a lot less. It seems the screen sucks a lot of power, and if you're not using it often a full charge lasts 4 to 6 hours longer.

I typically average between 1-2 hours of screen time on an average day. But I talk A LOT each day lol. I'm impressed with the talk time because I've yet to see a phone besides this one that can go 6 hours of talk time in the real world when connected to hsdpa. Also, if you think about it, 1.5 hours of screen time is decent use. It's not a massive amount of use, but it's definitely not like it's getting no use. All in all I have been pleased with the battery life.

I don't know about you guys but im very disappointed in the battery life. With wifi turned on the entire day and no calls, just browsing and chatting on google talk, i got 3 hours 54 mins of screen on time before the phone reached 12% battery. I think thstss pretty horrendous. I was hoping for 7 hours or something of on screen time. My galaxy tab 10.1 has spoiled me i guess. Illl live with it because theres no other android phone im aware of that will give me more, but im kinda bummed about it.

My iPhone 4 has insane battery life... I cant imagine having less. Hopefully they sell larger batteries + backplates for the Galaxy Nexus?

Same here tbh. And the really frustrating part is, I only have 2G where I live so I was hoping to see really great battery life. Hasn't been the case so far though.
However having said that, just last night I flashed XXIK6 and while it's still very early to say for sure, it "appears" that battery life has significantly improved for me. Currently sitting on 91% after 3.5 hours with very, very light usage, IE: 15-20 mins screen on, 15 min phone calls, etc. Nothing to write home about sure, but way way better than before. It would normally be around 80% by now.
It's really sad when the very first thing you do after unlocking your phone is to go into setting to check your battery. Wish I could stop obsessing and enjoy this marvelous device without having to worry about it.

What did you guys do after getting the phone.
Did you charge it all the way to full before use, use and charge at the same time, or let it discharge all the way and then charge it to full?
Thanks.

I would have to say that the GN has the best battery life of any of my previous android phones. (G1, N1, Sensation) These things are very subjective though.

Yeah, and I don't want to lose the thinness of this gorgeous phone with an extended battery, but 4 hours of screen on time? Anyways, can you let us know how that radio works out, I'm not expecting much, but still curious. If it is noticeably better, I will try to unlock+root this phone. I'm just a little scared to brick this 700$ device.

I'm just waiting for mod of web browser that will invert colours. Black backgrounds and white text ...that would extend battery life significantly. I swapped colours on xda app and pulse reader only browser left ha ha

The inverted colours app is already there isn't it? I saw it when I was fiddling about with the browser settings before

Yup, it's under accessibility in browser settings. Great if you read mainly text-only sites since it inverts image colours as well

2-3% per hour idle
I did a benchmark this afternoon for about 8 hours.
ITL41F rom, rooted + dcm kernel, otherwise stock. bluetooth, HSDPA, 1 gmail sync, and a few background sync that is very light.
idle the phone in home for 8 hours. the battery drops about 2-2.5% per hour consistently.

how long does it last with 'constant use' though?... from fully charged, to then having the screen on the whole time & doing web browsing, video watching, downloading, etc... (with data on, not wifi)

with data screen straight you may get 4-5hours. With wifi probably 6 tops.

Go Comment or Star for Battery Fix

I'm sure we all know that the battery life on the G Nexus is pretty awful, so let's all go star and comment on the issue so we can get Google's attention!
http://code.google.com/p/android/is...s Owner Summary Stars&groupby=&sort=&id=22878
Just scroll all the way down to the bottom and star the issue or leave a comment too.

Done and done... I hope this comes before I need to return the VZ GNex

Hmm, compared to my EVO 4G, I barely had to do anything to this to get the battery life to be very good (estimate 100 -> 0 = 15hours). Maybe I use the screen less than you guys though.

At home, no LTE connection. 5.5 Hours.

On GSM.. battery life is stellar.. keep in mind, like the person who posted above me that if you are in a low signal area your battery will be destroyed searching for signal..

Yeah I don't have LTE where I am either, but I have it forced to CDMA only. Android OS is my battery killer. I usually get around 6 hours before having to plug it up.
I really think that if enough people starred the issue then it will get someones attention! (Crosses fingers)

Please star, but don't comment. There is enough useless comments there already, and everyone gets notified on new comments.

you probably have a rogue app killing your battery. if I let my nexus sit idle with LTE on I get close to 2 and a half days

Hi,
This high Android OS Keep awake time is not specifically about battery life issue.
We are discussing the fact that, because of this, the phone is constantly waking up (wake up state).
And that's should not happen while the device is turned off, for example.
Yes, of course, this will relate to battery life at the end. But, that's not the point of the discussion / bug as everybody has different preference of battery life. One can say 12 hours is enough, while others may say 24 hours is not enough, according their usage pattern.

Yeah I don't think that is the case... even after rebooting it stills is draining even when idle...

i aint charged in 3 days so im all good

This is nothing new. Android is a batt hog, plain and simple. You think google doesnt know this already. Its an "acceptable" item. Where they know about it & it's not the best, but thats what they get if they want a phone thats constantly using the network, has a large HD screen and is so damn good to look at you wont want to put it down.
Quit itchin and get on with it....

I have the extended battery from Verizon so keeping that in mind, my phone lasted 14 hours with 10% remaining with normal use. I stopped testing since I had to go to sleep
By the way I have Beweather and Facebook updating every hour and Pulse updating every 6 hours. I also have endgadget, Cnet, Google currents, Flickr and 500px updating.

So far battery life is a bit lower than I would like but not to a horrible state. definitely going to need the extended battery though. playing around today to see how fast I can kill it.
can't get photo to upload now though for some reason but got 2 hours 10 minutes with 12% remaining. would kinda like to see that as a stat added to phone reviews, minimum battery life. Max is fine but I'd rather know how long it will last with power using.

I'd say battery life was less than great on 4.0.1 but 4.0.2&.0.3 its pretty damn good now my idle usage is next to nothing. 2 days ago i had 47 minutes talk time, 1h38m screen on and about 13-15 hours of idle and still had almost 40% left at midnight.

I think you don't understand.
This is not about battery life, but the high Android OS Keep awake time. Which means your phone was awake when it's turned off.
Obviously, this doesn't happen on my HTC Desire, nor Nexus S with Gingerbread.

I can't speak for battery life on the LTE Nex as i have the HSPA+ version...I've found that the battery life is quite excellent after a few charge cycles...Have gotten 21hrs on a single charge with normal usage...if i'm watchin vids or playin games then im putting my phone on the charger cuz the screen really does eat up battery alot.

Ughh battery drain definitely too fast.

I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.

Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?

Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.

Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

Wow, really? At first glance in all sub-forums I saw about two, if that. I have a legitimate concern, especially when my friend is getting about 4 times better life. Thanks for your help though in the device forum where this 'doesn't belong'.
..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.

I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel

From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.

Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise

[Q] Battery Case

Has anyone got a decent case with a battery in it?
as the nexus 5 does seem to have a not too good battery life.
(considering this device)

Seriously? I'm getting 14 to 16 hours with 6+ hours screen on time. It's not bad if you ask me.

I agree. I'm getting better battery life than any phone I have owned, without rooting and messing with cpu governors, or adding an unwieldy 3000+ mah aftermarket battery.

wow
from what I'v heard in reviews its not great, was about 5 reviews.
hmmm, Ill look into that a bit more
also geekphone.com is showing a not too great battery life

No, your not wrong, the phone is going to have less talk time than some of its larger battery packing competitors given the same use, physics works as they say. I'm on the lookout myself but have yet to see anything.

It could could be a software and hardware thing, as samsung does take a big dump on android. Pure android and especially 4.4 theoretically should have a lower power consumption.
how long does it generally last when mid-heavily used?

I can't comment on battery life, but I can tell you you won't be seeing a battery case. Only 2 products sell enough to make it a reasonable expense to develop: The newest iPhone, and the newest Galaxy S.

I disagree, my DHD had quite a few and it didn't have that many sales (probably less than nexus 5 in a month or so)

I'm getting much better battery life than any previous phones I've had. I can squeeze about two full days out of it with about 3-4 hours of screen on time. If I use it a lot (6+ hours screen on) or do battery heavy tasks (play a lot of games, talk on the phone a lot), then it still lasts a full day (from wake up to sleep). Unless you absolutely abhor charging your phone every night, I don't think it's worth the unnecessary bulk of a battery case.

Is this on stock? I understand that diff configs will have diff results. When I go to bed, I usually have about 40% left with 15 hours run time about and 1 hour of screen time. This is with two gmail accounts syncing, facebook and everything on. It's not bad but nowhere near 6 hours of screen time. Especially if I play a game like Asphalt 8. The battery drops like crazy. Not complaining, but I would love to have 6 hours of screen time.

I contacted Mophie to see if they had plans to make a case for the N5. I just got a pretty generic email back but looked like they would be working on something for the N5.

I didn't make it clear enough in my post, but when I said 6 hours of screen on time or battery heavy tasks, I meant one or the other but not both. If I play games or do a lot of battery heavy tasks,t hen it doesn't last anywhere near two days. I might get 6 hours screen on time if I don't play any games, make no phone calls for the day (which is odd, I do admit), and mostly browse the internet, text, view pictures, check facebook, things of that nature. On average, I get anywhere between 2-4 hours screen on time with usually an hour of gaming, mostly texting, browsing, and other small stuff like that. It usually lasts me 2 days. It's not fantastic battery life, but definitely better than my S3 and my Atrix before that.
EDIT: I didn't use my phone much at all today. I've got about 10 minutes of phone calls and an hour of screen on time, 13 hours total, and I'm sitting at 72%. You might want to check what is using the most battery in your battery settings or download an alternate app. Screen is typically using 2 to 3 times more than the next thing under it (which for me is WiFi).
