Help Battery discussions, maintaining battery life

[Lord Vader]

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.

Edit - ninja'd!

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.

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.

Agreed!

 

[Lord Vader]

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

 

[Tommydaniel]

Not me. A mere 3mm additional thickness is a no-brainer if it means I could use a battery 250% stronger than the original.

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

 

[Lord Vader]

Actually, the number should be 133% stronger.

From 1500mAh to 3500mAh.

 

[Lord Vader]

I'm not getting all up in arms over it; rather, it's just a change I don't like.

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 plus

 

[Lord Vader]

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.

 

[SamuraiBigEd]

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.

 

[Lord Vader]

No, it's not my reasoning. You miss my point.
