A-hem... I'm out and about right now, and I've already changed two of my batteries (Evo 3d) on my phone already. So, I'm hoping the ("non-removable") battery in the EVO 4G LTE will last much longer.

I'm sure the first couple of days will be the worst, so that's understandable.

What are you doing to chew that much power so quickly? 4G? Other?

I'm always using 4G. I get 'good' 4G and 3G signal here in the Big Apple. But I'm doing several other stuff on the web, as well as checking inside the forums on a regular. Busy busy... !!

Just got back home -- batteries are now charging and getting ready for a long night.

Amidst all this discussion of not being able to pull the battery, no one has yet to ask this--what does one do if his phone is rooted or otherwise has a weird problem like freezing or locking up, and, like now, a battery pull is the recommended way of fixing this issue?

Actually, it's been brought up at least two or three times in a few of the other threads Many have suggested that there will be an equivalent method (holding the power button down long enough or some power/volume button combination. I suppose we won't know until it's in our hands though.

That said, people have been modding/hacking/flashing Android tablets for some time now, and as far as I know, all or nearly all have sealed batteries inside. I think there haven't been too many problems there?

The shared expectation is that it will feature a Vulcan nerve pinch of several buttons to accomplish a true hardware reset. We haven't heard which buttons, but that sort of thing is common for phones with fixed batteries.

The HTC evo 4g has this option. I've been using it lately just to get used to the idea. You hold both volume buttons and the power for 10 or 15 seconds and it reboots to the bootloader screen.

Not the same thing as booting to recovery.

Have you owned a PC with a physical reset button? Worked identically to powering up and down without smacking the power supply with the on/off/on transient?

The Vulcan nerve pinch built in to fixed battery phones acts just like that.

Because as many of us will attest, you can be in the middle of a recovery installation for rooting and need a battery pull. Ditto on bad kernel install.

The HTC volume_down + power = recovery will still exist, that's a standard for them, and the Vulcan nerve pinch will be in addition to that.

And the boot to bootloader combo never required VOL-UP to be pressed. it was just POWER + VOL-DOWN.

I understand that but pressing the three buttons together will reset your phone. While having a Rom running if you use all 3 it will restart the phone.

I just tried this on my Evo 4G running CM7. I pressed power plus both volume buttons. Held them all down for 30 secs. nothing.

I hope the official ninja nerve pinch doesn't require that many buttons.

-edit-
i just saw under your Devices declaration that you have a HW 0004 Evo. Maybe 0004 supports what you describe.... mine is 0003.

I think you threw us when you said that booted to the bootloader screen. On a stock ROM, that's a straight reset.

Soft Reboot (found on accident)

Hold both volume buttons, then tap power.

Does that do a hardware reset? Not sure, maybe.

If this combo depends on it being a stock rom, that would seem to imply that it's not a hardware reset, no? A hardware reset should work regardless of the firmware currently loaded. That's the main reason we need this hard reset, is when we flash an AOSP kernel with a Sense ROM or something similarly stupid I've done in the past

Huh. I did it yesterday while trying out an ics rom that froze up on me. The phone wouldn't do anything so rather than pull the battery and then use power + volume down to get to the bootloader I used the three buttons to get there.

I'm just trying to say that if it works with a 2 year old phone I think HTC will have that option on the new one.

I would rather have a 8.9mm thick phone with a non-removable 2000mAH battery, than have a 12mm thick phone with a removable 1730mAH battery.

Not me. A mere 3mm additional thickness is a no-brainer if it means I could use a battery 133% stronger than the original.

How do you figure you will get a battery 250% stronger?

Actually, the number should be 133% stronger.

From 1500mAh to 3500mAh.

well it's gonna be even more than 3mm difference if you start adding in external batteries... i like my phone to fit in my pocket, i also like the idea of being able to take out my battery and swap it out but in all honesty, i don't even own a spare battery for my EVO so i'm not gonna worry too much bout this

Do you mean using extended batteries? The Evo 4G 3500 extended battery adds 6mm. That a little too much for me.

HTC could easily make a case like this for it. mophie juice pack plusŪ - iPhone 4/4S rechargeable backup battery case

I would buy that.

Or this..

My current 3500mAh extended battery with its larger door actually makes my EVO easier to grip and handle than does the stock battery and its size, which is why I like the bigger battery on my EVO.

Well said!
I too bought the Extended Battery option want I got my EVO last summer. It did make my phone fatter, but I agree that it also makes it easier to handle. More importantly the battery life is great with the extended battery.

I have the 4000mah Seidio in my 3D and it is awesome. I also have very large hands so the phone still feels tiny to me, I would be happy with a Note size phone with extended battery!

That said, the difference between 1730 and 2000 is not going to make that big of an improvement itself, it will require power saving improvements at the hardware level to make it truly useful.

I bet 99% of those complaining about battery life on the Evo 4g are the ones who have yet to root. The increase in battery life from flashing a good rom or kernel combo or just watching what radios are on is amazing. When I first got my evo I was getting max 4 hours on the battery, with hardly any use. Today I can go 12 hours easy with a good amount of use and never turning off 3g. My roommate gets the same awesome battery life when I rooted his phone. He came from an iphone and now can't imagine even getting this kind of battery life on his ip4. If its possible to get great battery life on the poorly inefficient Evo 4g with a few tweaks why is it so hard for people to believe that a new Evo that's three generations ahead in efficiency will not get decent battery life?


Also, take a look at any other forum and you will see one common complaint: Battery life. It doesn't matter what phone it is people will still complain that the battery doesn't last. Two of my close friends have ET4Gs and they complain non-stop about battery life. Talk to any samsung fanboy and they will tell you Samsung phones have awesome battery life but are they really any good or worse than HTC or Motorola or any other manufacturer? Until someone can design a study where they can get people together with multiple phones with steady controlled usage and get a statistically significant difference between one or the other I don't believe any phone is really any better with battery than another.

And with that said, I think the new LTEvo will easily be a 12-24 hour phone. If you can do it with the Evo 4G then it will be possible with the LTEvo. I have an upgrade right now and can't wait for this phone

And I'd bet you're wrong. My EVO is rooted, and like many others whose EVOs are rooted, the best ROM and kernel in the world often is useless when the phone is, to put it bluntly, being used a LOT. Sometimes it's the users fault--want to play all frickin' day Angry Birds or use a similar app that hogs your battery life? Then be prepared to have your battery drained much more quickly. However, there are those whose batteries just seem to go quickly, more so than desired, and a different ROM or kernel doesn't help.

What's your point? Show me a phone that can last 12 hours playing Angry Birds. If this is your reasoning for buying a phone then I think you should look somewhere else.

i don't think that was his point, i think what he was TRYING to say was that a phone with poor battery life will always have POOR battery life... even if you root it and run custom rom kernel it's not going to improve it SO MUCH that it won't be bad still... just better than it was

i will agree to this. i got ~ 9-10 hours on stock rom with medium usage (texts email calls, no games) and currently running AOKP i get SLIGHTLY better, im looking at 12 hours average per day, its better but by no means GOOD, i feel like i'm barely using my phone...

what is a baseline for GOOD battery life? I've seen Earlymon make the case that what our phones do compared to a laptop is pretty amazing but we expect our phones to have 10x time better battery life.

Good battery life is purely what the user defines it as

for ME, good battery life is this:
i should be able to text, email, make a few calls, surf the net a little bit and play a few video games over the course of 12-14 hours

if it can't even handle that it's not "Good" in my book, my EVO comes close, i just can't really play games at all, if i even open a game i better have my charger on hand cause i'm NOT making it through my 14 hour day

a phone should be able to do what it is capable of for 12 hours... i'm not saying 12 hours straight, thats rediculous, but i should be able to play angry birds for 30 minutes and still be able to trust my phone will make it through the day

Any given action requires a certain amount of processing power (aka battery life). If your phone is not draining much when you're not using it, then you're getting good battery life. If you think you aren't, your expectation of power consumption probably needs adjustment. Like someone else said, these phones are doing a lot of work. When you compare the same work to a laptop, these phones are almost an order of magnitude more efficient.

From my experience, the people with true battery life problems are the ones that can claim they just have the phone in their pocket the whole day, and it's dead before night.

The problem with quantifying battery life is that everyone's definition of usage is subjective. My moderate usage won't be equal to your moderate usage. Some functions use more power than others, so even if your phone usage is short, you could end up with a dead battery faster than someone else.

I would submit that we're not driving anywhere near the display size or a hard drive. And there's a big difference in battery sizes.

I get about 5 hours of hard use (by any measure) from a laptop.

I expect moderate use of a phone to exceed a day, and moderate / heavy to last nearly a day.

I agree that moderate and heavy are strictly subjective, but I take the same position as the Supreme Court did on porn - I know it when I see it.

Social networking syncing is a battery hog. So are instant messaging apps. It's tempting to have an instant messenger running and have no messages go in or out, and call that low use (because the observer saw no action) but that's not true. And that's an architectural issue beyond Android - but the phone is always blamed.

Were we to see improvement in push technology for all areas of weather, stocks, mail, messaging, social stuff, etc etc, we might more quickly agree on these definitions of use. Too many apps work in processor and network intensive loops seeing if new information is available to be pulled in, and these are the battery hogs.

Let me put it this way.

If you run nothing, just idle, you can do it for a very long time, yet never miss an incoming call, or SMS.

That is an example of perfected push technology.

Other apps need to behave like that.

I don't think we have that much to worry about when it comes to battery thus far. The one x and one s have been getting pretty good battery reports and standby results on 3G. With the bigger battery on el tevo, along with hopefully a fix on that misplaced apk, it should be pretty impressive.

FYI, misplaced APK is a non issue for the LTEvo, as it will be using the Qualcomm S4 Krait and not the nVIdia Tegra 3 (for which that issue is specific to).

It's official: consumers have voted and that's why the One X/LTEvo has a sealed battery. Thinness is in.

HTC: customers prefer thin phones to better battery life | The Verge

Quote:
At an event today, HTC's vice president of product strategy Bjorn Kilburn noted that the company had conducted research last year to find out whether customers preferred thin smartphones to those which compromised thickness for better battery life. The answer, interestingly, was that they generally preferred thinness, at which point its plans for 3,000mAh-plus devices were removed from the roadmap.
It's not particularly surprising though, as the most popular smartphone of all time, the iPhone has had a sealed battery since forever, and that fact has not stopped consumers from buying them in droves. It's too bad however that the standardized design of the iPhone means plenty of battery packs/battery cases/battery chargers to choose from. We won't be as lucky.

The problem with "market research" is the cross sections are quite often not an accurate representation of the public or device users. Many of these studies are a general at large study and can miss the target, what the general consumer wants as opposed to the business or power user can make a huge difference.

Everybody I personally know has gotten all excited when I mention the LTEvo until I tell them about the battery then they all say the same thing, forget it. Granted we all fall into the latter categories but not one of us ever had any communication from HTC about market research and I have been with them since the Mogul and am a member on the HTC forums.

My hopes are that HTC will wake up and make a Note size phone!

My EVO loses battery life doing nothing, but whatever. It's almost time for a new one.

Main question, in the sticky there is a linked review where the poster states that the lte battery is 7.5 hours. What does this mean compared to the EVO original in comparison?

We have a someone in this forum who actually gave a review of the One X and said he got 15hrs out of the phone. Granted this is not LTE included as the One X doesn't have LTE, but I think that good and could give us a round-a-bout guess where the LTEvo can do, and also considering that the LTEvo has a larger battery!

That's nothing. My sister has the 3500mAh extended battery on her rooted phone. Within 2 hours of unplugging it from its charger, it drops from 100% to 60%. It goes completely dead within the next 3-5 hours. She has double-checked and stopped every app or unnecessary process that she doesn't need running, too, but that hasn't helped. I told her odds are that it's her battery--a bad one.

"rooted" tells us nothing. If shes rooted and getting terrible battery life even with a huge ass battery then it is her fault and she needs to figure out a better Rom and Kernel combo.

She's using the same ROM and kernel combo I and many others are using. That's not the problem. It's most likely a battery gone bad.

Yes! America wants fast and it will come at a cost! The LTE chipset is new, and in the future they will make it more efficient and consume less power. Think of it like the PS3 they had the fat model and later on they built the slim version that consume less power and more efficient!

Sauske you are in my neck of the woods..maybe we will get LTE pretty quick like with the 4g.

The problem with 4g is it sucked my battery so fast that I could never use it.

Also until I rooted my phone I would lose range super fast with even 3g.

My coworker has an Iphone and we went to a convention..browsed the web a little..called people..texted and my phone was dead by 3pm. She was at 20% before we turned in for the night.

So im a little bitter over the battery life from the EVO..lol. And this is with multiple kernel/ROMs and a new battery purchase as well.

Yes the 4G zap the life out of the battery! I'm rooted as well, but every once in a while I would get signal issue! At home I actually get one bar in a certain spot !

What brand is the battery? Where did she get it from? I had an extended battery on my old EVO and it lasted over 18 hours with moderate to heavy use. I bought mine on ebay.
