The Official Battery Life Thread

**jasonb1108** · 04-25-2011, 06:12 PM

I love my Evo but if the battery life on the EVO 3D is just as bad I will be disappointed. Wish their was a Android Phone with decent battery life. My Evo is on a diet no fat extended batteries for me.

So far, all the phones i've seen with these monster screens have had fair (at best) battery life... I would imagine it would be better being next gen hardware and software, but expect it to still be pretty low. The atrix is advertised 9 hours talk time, that would be the very upper limit.

Yeah 9 hours without doing anything else but sitting there with the screen off on a call.

This comes up all the time. If you want the phone, but you think battery life will be an issue, then keep a charger with you or carry extra batteries.

also remember the battery capacity on the 3D wil be quite a bit higher than other HTC phones.

**Saneless** · 04-28-2011, 09:43 AM

There should be quite a bit better battery life in the 3D compared to the 4G:

The EVO3D battery is 15% larger than the battery for the 4G. When you've run out of battery in your 4G, pretend you had 15% more..

Die size. The 4G's processor was 65nm while the 3D's is 45. Less size=less power to run.

Faster, more efficient CPU. More efficient/fast cpu = instructions finish quicker = quicker to enter sleep state. Sleep state is where you get all your CPU power savings. If its max power usage is lower and it finishes processing tasks quicker, it's definitely a win.

SLCD Screen. SLCD is more power-efficient than LCD, so there should be a little bit of power savings there.

I'm not too worried about it.

Processor size does not always mean less power consumption. In fact the newer processors under peak load use more power than the old ones, despite the size.

Speed is a direct relation of power use, because a processor or core can run faster, its because it more wattage can be pushed through it. (think overclocking)

as for the screen i hope your right.

That being said, i remember i would be happy with 6-8 hours on my stock evo, so this will give 8-10? I'll take it where i can not that much of an improvement if you ask me...

I'm dorkin' around with my buddies Atrix later this week, i'll bring back some battery usage stats via Juice Plotter

The thing here is, you will be running at peak much less often with the dual core processor, so the majority of time, you should see less power consumption.

**Saneless** · 04-29-2011, 09:51 AM

Overclocking simply means you're running the processor faster than its yield says it should be at as it ran stock voltages. Today's CPUs are so much faster than older CPUs and use so much less power it's not even close.

As far as time goes, I use my phone until I leave work, and it's at usually 30-50%. The drive home usually does a good job of charging it up another 30% so i'm fine by the end of the day. Pretty much the same experience as my iPhone.

**error4o4** · 04-29-2011, 09:04 PM

Hopefully there will be a rom for the EVO 3d like the Fresh Rom for the EVO 4g.

I easily get 12-15 hours of moderate use using Fresh roms vs Stock or even Cyanogen

How are your battery life numbers out there?

The Evo 3D is running laps around my old hero. The same amount of web browsing / game playing / tune listening on the hero would have killed the battery in at least 1/2 the time of the Evo 3D (if not quicker). I know this is a brand new battery, but I expected worst results after all I heard from the original EVO.

Anyone upgrading from an older Android phone and pleasantly surprised?

**Tyler Durden** · 06-23-2011, 07:08 AM

I'm coming from an EVO 4G, too early to tell for me......

I'll get mine tomorrow, but anything is better than my Pre

**fivegear** · 06-23-2011, 07:24 AM

So far I am impressed with battery life

**chubbs123** · 06-23-2011, 07:27 AM

I've been really hoping that the battery life is better then the stock battery in the evo 4G. That was my only complaint about the phone originally. Then I bought an Extended battery. Problem solved.

**resur** · 06-23-2011, 07:51 AM

Since unplug from a full charge overnight, I am at 95% after 3 hours with moderate usage (can't keep my hands off it!).

So, so far so good!

**kcodya** · 06-23-2011, 08:16 AM

Kind of too early for me to tell right now. I will say though, with the amount of web browsing and other stuff I did last night, my original EVO would have used MUCH more battery than the 3D did.

**zmann** · 06-23-2011, 08:17 AM

I have noticed a big difference. This device is much better battery life.

EVO - LUTION 3D

**Jace985** · 06-23-2011, 08:23 AM

Good to know coming from the iPhone 4 that honestly had one thing going for it and that was the battery I'm glad to hear that you guys are getting good battery life

**destroyosaur** · 06-23-2011, 08:26 AM

It took me around 5-6 hours of non stop use to drain the battery. That was with brightness on auto, wifi, bluetooth and gps on. Much better than my pre.

**sed51329** · 06-23-2011, 08:41 AM

I'm power using right now, and the battery is lasting 5-6 hours....it's amazing. My 4G would have died in 3-4 with this much use.

**darchenwar44** · 06-23-2011, 09:32 AM

I am just curious, as I've read in the reviews that the battery takes a hit if you are using wimax. Are the good battery life comments coming with wimax enabled or just 3G?

I'm using just 3G, but I did that on my EVO 4G also. There's no 4G in Wisconsin, other than a very faint signal once in awhile.

4G isn't really needed on my end.....I didn't know that processor speed has such an impact on browser performance. Pages seem to load, at the very least, 25% faster than on my 4G.

**mechlife** · 06-24-2011, 09:25 AM

I have the Pre and got the HTC EVO 4g which I returned. Someone made a really good comment, what is the point of having a feature loaded phone when you have to turn everything off, hit home for me. I wasn't even getting a day of normal use. What is the feel for battery life on the EVO 3d?

**pirarre** · 06-24-2011, 09:33 AM

I received my phone Wednesday. I've 10-12 hours on one charge. And that's with lots of testing, browsing, downloading apps..etc. I have a car charger in my car so I'm happy if the battery lasts the 8 hours that I'm at work. But to get anywhere from10-12 hours is great for me.

Oh and I didn't turn any features off either...

Delivered to you from my Simply Brilliant EVO 3D!

**Divegeek** · 06-24-2011, 09:35 AM

I am getting good battery life. I have had mine for 3 days now and been using it pretty heavy, and each night when I go to bed it is at 20-30%. Much better than my Pre
