The app won't setup up the notifications for you automatically. You have to set it up yourself if that is what you are asking.

Vipfreak · Jul 3, 2011

No, there's a batt icon with the % displayed in the taskbar. I'd like to get rid of it.

No, that's the primary purpose of the app is to display on the taskbar.

Ugh.. ok, thanks.

Waiting for a siedo 3500 for this phone. Once I have that i will be straight. This phone is definitely better than the evo, but not than the evo with a siedo 3500 battery.

When is that battery coming out ?? :cool:

First post on these forums!

Having upgraded from a Hero, I'm all too happy with this phone. Today was my first full day handling this beast and my battery results were awesome. Of course I had to meddle with a few settings and whatnot, but nothing too crazy was done.

In a nutshell, I unplugged this bad boy and 9AM, and fifteen hours later I was down to 15%. All day I had been surfing the web, texting, HeyTelling (sparingly), using Pandora and Slacker internet radio for about an hour, and taking/playing back a lot of 2D/3D pictures AND videos. Whenever I wasn't using anything internet related, I turned off 3G. I did not use bluetooth, WiFi, GPS, or 4G. For my particular usage situation, I'm more than satisfied with the battery life, along with the fact that I don't and won't feel the need to carry the charger around with me.

And also, just as a side note, I had a Seidio 3500 mAh battery with my Hero, which lasted me 48 hours a charge. Having said that, the custom backing was very, very loose, and the battery wasn't very snug, which resulted in the phone randomly shutting off at the occurrence of even a mild bump into something.

LOVE MY 3VO!

What is your signal strength? If it's less than 4 bars, I've found it does drain battery. Also, do you have 4G enabled? Even worse battery drain especially if not at full signal strength.

The low signal strength drain is the biggest problem Sprint has, I think. I've had this problem on every Sprint phone. I wish someone would make the "use all available power to search for better signal" algorithm a bit less aggressive. In fact, if I have poor signal AND am doing data over 3G, the phone gets hot! Turn on WiFi if you do this (if you can). That's been my solution for years.

I get 16+ hours on my phone, now, with push mail on four accounts, 15-minute updates on other accounts (twitter, some email, etc.) <10 minutes of voice, a few texts and 1+ hours of web use (not downloading that whole time, of course). At this point, I'm a bit under 30% charge, on average... extrapolating (which is not quite valid, but whatever...) that's 22 hours. I'm not playing online games or watching movies, but I do watch a youtube video occasionally, for example. I'm not trying to save battery, but using the device as I think I should.

Finally, here are some screen shots clearly showing what others have said (including me but now I have photos):

1) Notice what happens as you get to 100% charge:

2) Here's my last three days of usage to "prove" what I'm saying, above:

what app is it that you're using for the graph?

I think my battery is better at idling when I uncheck the box under Power settings to efficiently control the phone/Auto sync.

OK, so I seem to have a somewhat major problem...

Out of the blue tonight I noticed that my 3VO will not charge at all. If I take it off the charger it will go down but it will not go up.

I have done many many restarts (soft resets) and a battery pull. I have also attempted to update the Firmware and HTC updates to no avail. It says there is nothng availiable on both 3G and WIFI.

I have uninstalled and reinstalled the battery widget many times again, to no avail.

I am hoping I do not need to do a hard reset. Any help would be MUCH appreciated :thinking:

Edit 1: Was plugged into an ebay bought OEM charger. Put it on OEM charger that came with the phone and it is charging. Now testing ebay bought OEM on different powerstrip on a different wall socket.

Edit 2: OEM charger bought on ebay has been deamed flawed. Switching cables and power plug has proved it is the ebay bought socket part and not the wire part.

Edit 3: Both (Bought 2) ebay OEM socket part of the charger are flawed. One wire is good. The OEM charger that came with the phone is charging strong. It's strange because they both came with the packaging that came with the phone and look exactly like it. Contacting the seller now.

Edit 4: Message sent to seller. FYI seller is based out of Chicago, Illinois

Was the charger and cable cheap? Typical problem and the higher end cables last longer. My boyfriend bought this $12 cable in Korea for me 1 year and a half ago and its still going strong for charging both of my phones.

Well that's the thing. I bought 2 OEM chargers and cables from this seller and they came with the packaging just like the one that came with the phone so I was like "Man! What a deal...$4 something for each?!"

Just weird :thinking:

I will report back with what the seller says...

Edit: Both sockets and one wire were bad . I did a control test with the sprint OEM every time too.Very weird.

Makes me wonder if they were fakes.

Just wondering what the consensus is out there. I am not having battery issues at all. In fact, I am quite impressed with the battery on this phone. But as is the case with most of us, I was just cruising thru the settings menus and decided to take a look at the battery stats. It is showing an awake time of approx 50% of up time. On my 4G that figure was always around 20%...ish and that seemed about right. I am a moderate user. I will admit my "syncing behavior" is a little different on this phone although I have most of my syncs set at 4 hours or more. Anyway, just thought it a little interesting. What are y'all seeing????

On a related note....I did notice on my 4G while running 2.3 and this phone which runs 2.3 that in the battery stats, it is a function of actual battery usage instead of a function of time "awake". So in Froyo and everything before, we always saw the Android OS at the top of the list because it spent the most time "awake" but did not use the most battery. Now we are seeing the true battery users and #1 is almost always the display....just an observation....

After having the phone for a week and a few days my opinion is that the battery life is decent but not spectacular. This is not necessarily the phones fault as I am often in low signal areas which drains the battery quite amazingly fast (especially when it is attempting to switch from Sprint to roaming and back). I've learned to just turn on wifi at work and home and turn off mobile networks when I am on wifi to help the battery. Playing words with friends seems to be a surprisingly large battery drain but I think that is due to keeping the screen on while viewing the board and taking time to crush my friends with a 99 point word.

The phone lasts through the work day where it comes off the charger at 8 am and gets back on the charger ~15% at 8 pm. and that is pretty decent but I can't imagine taking this phone out for a weekend with no charger or anything.

I send about ~30-50 texts, 5 or so emails, and have one or two 10 minute calls per day and play some words with friends. I am happy enough with the battery life but not impressed. I mostly blame Sprint but it still results in just average battery life.

Still better than my friend's thunderbolt battery life.

My brightness is on the lowest setting, my wifi, hotspot, 4g, bluetooth, and GPS are off, only mobile network is on. i have advanced task killer set to autokill on screen off, and i also have juice defender set to aggressive. i charged my phone to 99% (according to my flashlight app) and then unplugged it. over the next hour, i sent and received maybe 10 texts total, and placed one call, otherwise leaving my phone alone. after 1 hour, my battery had already dropped to 85%. Something tells me that with all those settings set the way they are, I shouldn't be losing 14% in an hour. What can I do?

axisofoil · Jul 5, 2011

Get rid of autotask killer.

TheFrigz · Jul 5, 2011

Can you explain why? How else will I close all the apps running in the background? I'm new to all this

marctronixx · Jul 5, 2011

the frig, if you are new to android you may need to read the sticky thread up top about the phone and also read the manual on the handset. there is a task killer already installed however its wise not to use it. there is a thread on the task killer which you should also read over.

if you have trouble finding this info, send me a message offline and i will point you in the right direction.

TheFrigz · Jul 5, 2011

Ok then, I've removed task killer, but i kept juicedefender on agressive, hopefully it will make a difference. the guy at the sprint store told me to put task killer on, that's why i did..but it seems like android pretty much does that for you

EDIT: here's my battery usage:

display 47%
voice calls 26%
cell standby 9%
phone idle 7%
android OS 5%
internet 2%
messages 2%
voicemail 2%

and i'm down to 69% after 3 hours. that means i've lost 30% in 3 hours, barely doing anything with my phone..something seems off here.

flyjbaker · Jul 5, 2011

Frigz, also the way the charging cycle is set up on these phones you will lose about 10% off of the top in very little time. What happens is the battery tops off and then the charger turns off and then the phone sits there...ON...with no charge on it. The gauge will say it is 99% when in effect it really isn't. So that first bit you lose right off the bat is very normal and misleading. ANd generally, you should not have a task killer set on autokill. I use task killers for certain selected purposes but generally don't use them. I would suggest you do the same and do some tests to see if it is actually helping you....it could be hurting your battery life.

And to the moderator that moved my thread above....I had an idea somebody would do it and I also had an idea it would get buried in this thread and get no action....oh well. I thought it had merit to stand on it's own. I was interested to see how it compared to other folks...

You need to use wifi whenever possible and you need to make sure your screen cut off period is short. Also stay away from live wall papers and when you can, disable the mobile network.

i think part of the problem here is that i'm such a noob, i'm not sure what all these different connectivities are actually used for. for starters, i dont know how to turn off 3G. does 3G = mobile network? also, wifi is less of a battery drain than mobile network? what does turning off the mobile network do, make it so i cant get texts/calls any more? can the phone use wifi for texts/calls? i know i sound dumb but i'm struggling with all this haha

i think part of the problem was the weather app i had installed that updated constantly. i've removed that now

Pull down your notification bar from the top of your screen, then select quick settings. All of the different radios will appear (3G = mobile network, 4G, bluetooth, WiFi, Hotspot, etc). Make sure the 3G/mobile network box isn't selected with a green check mark.

Yes, you can still make calls and receive text messages without 3G, 4G, or WiFi on. But if you want to download voicemail to your phone you will need to have one of those radio selected meaning turned on by using the quick settings tab in your notification bar.

If you have a weather app that's allowed to update every hour and it pulls a lot of data its going to consume a lot of battery power. Especially if you are in a poor 3G or 4G area. If you are near WiFi, use WiFi whenever possible.

I would have to disagree with the live wallpaper analogy. I run a live wallpaper and I think it doesn't affect battery life with the EVO 3D. As I stated before, I go under Menu - Settings - Power - deselect the box titled power efficiency. My battery idles better since I'm in a some what bad coverage area in my hotel. I think I do a better job than the phone of managing the "device network" than that power saver setting. Can you guys deselect that box and see if your phones idle better too? Then again I leave all of my radios off.
