Evo battery thread (charging, size, replacements, aftermarket..ect)

**donald.aleshire** · 03-23-2010, 08:19 AM

I looked at the specs regarding the HD2, the battery life looks decent. The size of the battery is a little small when in comparison to the size of the actual device. In some reviews I saw, people said the battery life was average but the standby time was outstanding! 290 hours or something like that

Now, that is running WinMo 6.5 with HTC sense covering it up. Does Android do a better job managing power for this type of phone? Just wondering people opinions. I also hope they put a large battery in, maybe a 1400mh battery...

I guess we will all know soon enough, but any opinions?

1500mh battery listed in the specs so if it can be compared to the HD2 it should be fine.

**donald.aleshire** · 03-23-2010, 06:53 PM

Well it actually has a much larger battery then then HD2!

I love this! The battery on any smart is a key thing and it seems like this is easily taken care of with this monster 1500mAH battery!! Love it

That's a great question and something I'd like to know too. Has anyone seen any comparison testing on like devices between Winmo and Android?

**jhamilton3#CB** · 03-23-2010, 10:26 PM

I feel like battery life is going to be the biggest question mark about this device heading up to its release.

Seems like it would need an unheard of battery to run such a beast of a device.

**eve6er69** · 03-23-2010, 10:29 PM

i cant wait to see what seidio does for an ext battery too!

**Andrew Ruffolo** · 03-23-2010, 11:37 PM

It should be more efficient than a Hero which has the same battery. That being said, that screen is going to draw some serious power. I have a 3500mAh for my Hero now, interested as well what seidio cooks up to see if the width will be barable.

**LCW** · 03-24-2010, 11:32 AM

the EVO's battery is still just a 1500 mAh battery... which is a bit of a dissappointment... I'm running a Seidio 1600 mAh battery with my Nexus, which came with a 1400 mAh... so 200mAh/14% improvement... good for maybe an extra hour or two a day with typical usage... still not that earth shattering... can't in a million years ever think of going two days without a charge... it would die overnight regardless of what I do...

hoping the EVO 4G battery life is no worse than that of the Nexus... otherwise, might was well carry a spare battery and a charger everywhere you go... maybe even one of those solar panel chargers...

lol

**csierra72** · 03-24-2010, 02:23 PM

I know the headaches I have had with my Pre's battery. I'm willing to take a chance on this but I am sure we will see some testing and reviews in the near future.

**Ozmodiar** · 03-24-2010, 05:00 PM

With my Palm Pre (HORRIBLE BATTERY), I have a "patch" installed to allow me to turn off the data services, which increases battery life A LOT.

Can you do similar things like this with Android, or will I need to get some sort of custom ROM to do this?

Not sure the screen will draw too much more power. If you look at the resolution, it has the same specs as the N1, so the same number of pixels are being powered. However, the lack of AMOLED will increase power usage.\

I am more concerned about CDMA vs GSM for power consumption. I believe in the past CDMA has been shown to be more power hungry.

**Ozmodiar** · 03-25-2010, 04:30 PM

I think this was posted before in here...but I'm not sure.

According to Sprint's Developer Page, the screen IS AMOLED:

**Complex Pants** · 03-25-2010, 04:49 PM

engadget seems to disagree:

as does BGR:

**Ozmodiar** · 03-25-2010, 05:11 PM

Yeah...I had read the Engadget one before, and I've certainly seen the "Official" spec sheets be wrong...so it'll be interesting to see who ends up being right.

**justinsaneeeee** · 03-25-2010, 07:22 PM

This phone needs a big battery like bettween 1500-1650 mAh because it runs HDMI which will run the battery and HQ videos from youtube it has a 8MP camera and not along all the widgets that will just run that thing so yes battery will be the big ? the specs yes AMAZING price well we will see and battery big ?

**Andrew Ruffolo** · 03-25-2010, 07:33 PM

It has a 1500 mAh battery. Same as the Hero, which runs on an inefficient OS and slower processor and gets about a day. Mix that with a 1Ghz (may want to underclock when not needed to save battery) which in theory would be more efficient, 2.1 which is definitely more efficient, but a ridiculously huge screen (in a good way) which could be a drain depending on technology used. AMOLED would be a pain in sunlight, but would be a better choice for battery conservation.

**russellpr** · 03-31-2010, 05:05 PM

For me, the main battery concern with this phone twin radios: 4G and 3G. Since we've never seen a phone with WiMax radio, it will be interesting to see what "adequate" battery life claims will mean once this phone gets into the wild.

/AGREE!

The device must actually have THREE data radios in it, CDMA, 802.11b/g and 802.16 (WiMax). Don't know about you guys, but unless you're sure you're in a 4G (which isnt really 4G anyway, its Sprint's current iteration of HSDPA) coverage area I'd turn WiMax off (if that's possible) and I usually leave WiFi off on my devices unless I'm at home or the office for a while, where I know the signal is stable.

BT and a gps receiver.

You can turn it off. There's a widget to turn 4G on and off if you'd like.

The battery life is absolutely a concern. Those of us that have a Pre can attest to that

. It's 1100 compared to 1500 of the HTC. Doesn't seem like much more considering the size of the screen, and the many uses (watch movies). Good thing the battery is user replaceable.

It is a 36% increase, which is substantial. However, I think a more telling factor would be the snapdragon processor, which is supposedly more efficient than the OMAP 3430 in the Pre.

The screen (pixel wise) isn't larger than the droid's. Any droid users here want to comment on their battery life? For those who don't know the droid uses a 1400mAh battery.

We can also compare to an N1, except GSM has very different power usage because the way the radio's work.

**Andrew Ruffolo** · 04-03-2010, 05:35 PM

I would say my Hero with the 1500mAh battery life is MUCH better than the Pre. I had a pre and with my use, I would get about 5 hours, which was unacceptable. I get a full day on the stock 1500 battery, 2-3 days with the 3500mAh Seidio battery. Also, I've found the battery life with my latest 2.1 ROM (not optimized) to be better than 1.5 (optimized), so that will also be a factor. I believe we will also see 2.2 or whatever Froyo will be on this phone at release since WiMax isn't officially supported in 2.1 Android. I doubt they are going to patch it together like they did 1.5 and the Hero. With 2.1, there is a significant difference on how fast the data connection is, which probably had something to do with compatibility.

**Bbold9700** · 04-20-2010, 09:30 AM

Hello all new member here. Like all of you, I'm very excited for this phone to come out already. I know touch screen phones pretty much suck on battery life. (One of the reasons why I went to BB from iphone). My question is has anyone heard any good news about the battery life on this phone ? I know people don't really like the battery life on the htc hd2 which has the same screen.(I don't know if the battery is the same though).

**Andrew Ruffolo** · 04-20-2010, 02:12 PM

It has a smaller battery, but generally speaking, if you were to have a GSM and CDMA phone... the GSM phone usually lasts longer. I'm not too worried about battery life, I get decent out of my hero which is inefficient and has the same battery as the Evo. There is an app I've used for a couple of days now which conserves battery pretty well, its called juice defender, that helps conserve battery when not in use by regulating background sync.
