Battery life? Is it really that bad?

Gizmodo and MobileCrunch have pretty much bashed the battery life to make it sound like if its not on the charger, it will die in a matter of an hour or three. For the people who got one from the I/O or other means. What do you get from the phone during a normal days usage? If its that bad, have you guys use SetCPU/Locale/App Killers etc? Thanks.

With light to moderate use, it lasts through the day. A bit worse than Nexus One in that respect, but not too bad.

Agree with sergey.povzner.
Android central had a great review on this. I have heard a mixed bag of battery life. Some sounded very good some didn't. But it's the most power smartphone out there so additional drain is expected.
http://www.androidcentral.com/review-sprint-htc-evo-4g-android-smartphone

It not as good as my n1 but its close. It gets a lot better with custom roms without sense.

Uptime 10:08:35
Awake time 1:46
I had it plugged into computer for about 25 mins to transfer a movie.
I have 80% battery left.
No bluetooth, no GPS, no WIFI.

I don't have anything extra except gmail and another account frequently syncing. I get 4-5 hours of browsing and email with 4g on or off, wifi off, gps off. Standby time doesn't seem to have significant effect though I'm sure it would be measurable if you left it in standby for a day. Adequate to get me though a day, but I hardly use voice.

What if you are watching full length movie on HTC Evo, how long will the battery last (especially if I put it on airplane mode)?
I am planning to switch from from Xperia X10i to HTC Evo. My x10 has the usual battery drain problem but I have controlled it with task killer. However, I am yet to run a full movie on it. If x10's battery life has more survival time (with task killer on it of course) then HTC Evo then I might think twice.
Also can the 'task killer' improve HTC Evo's battery life?

Does anyone know if the Evo uses the HTC Touch Pro size battery like the Hero?
If so then I've already got an external charger and three extra batteries!

Honestly if anyone is that worried about battery life get another battery as a backup. Its been said many times on these forums that a HTC Touch Pro 2 and also a HTC Hero all use the same batteries as the EVO. (Confirmed). You can pick them up on ebay for around 7 or 8$. Which is pretty cheap! Nothing better than having an extra juice pack laying around waiting to be used! Hope this helps somewhat

i'm so excited, wish I had an extra battery though, it'd be nice
8hrs 15min till i get mine!

Gotta say this thing blows my old Moment's battery out of the water... 4.5 hours hard and heavy use... 60% left - no 4G coverage area (but it was left on by accident - ooops) and no video watching, but heavy text, email, and facebook/twitter activity.

I ordered the extended slim battery from seidio.com. 1750 vs 1500. Should give a bit more in the long run.
Its been decent for me though. Just dont jack up your brightness, keep it on auto.

Wifi kills my battery. The signal never settles even though the coverage should be good all over my house.

You want to go into advanced wifi settings and change WiFi sleep policy to never otherwise your phone will shut off WiFi after 15 mins of screen being off and you'll be using 3g which will use a lot more battery.

Its already set to never.

Mybattery was pretty terrible. Lose 10% per 40 minutes on standby mode alone. After messing around with it for a while I discovered the culprit was the location services. I turned them off and now I lose about 2% per hour on standby.

I'm curious, how exactly do you go about turning off the location services? Unless it's included with the GPS tab of the settings, I haven't been able to find such an option on my brother's Hero.

3rd day with phone, 2 self resets already

Ok, so what happenned on the 2 instances that this happenned was all of a sudden I lost cellular signal and the phone made a sound and the signal bars switched to a circular sign with the line across it. I put the phone in airplane mode but nothing happenned, within a min phone restarted it self...
The phone is stock. No root or anything like that.
Ps... using the keyboard to type this, and its much easier compard to my old droids kb.

Weird. Haven't experienced that before myself. I have had it lose signal and display the circle with a line through it but it's not very often and only for a second or two.

Just did it again when I went into pandora. I realized its actually not resetting, but the phone freezes up and everything reloads. Including signal and 3G... the screen shutz off and you can't turn it back on until it reloads

Sent from my Epic 4G

I had the same problem on my original Epic. I had three problems in total on that phone.
Samsung's crap coding that caused the phone to not sleep. (fixed after 2nd update)
The phone would randomly restart itself
During calls, the screen would freeze while illuminated. The call wasn't interrupted, but aftwards I had to pull the battery.
In the end I had to exchange the phone for another. Only problem was, the new phone had that couple millimeter gap with the slider. Sprint said it wasn't enough for third exchange though.

Man, this sucks... Just when I put all the apps I wanted on it and got it running the way I want it...
I'm gonna give it 1 more week see what happens, then return perhaps for another epic. I'm pretty sure I'll be sticking to the epic though, i really like the camera capabilities of the phone.
I'm actually going to run 4 tests this week
I'm going to leave the phone untouched from 10:00 to 21:00 and note the percentage in battery with juice defender on/off and also noLED on/off, see what happens... to make it even, i'll just leave the phone in my car, and it won't be used except it's usual email checking/texts/missed calls etc.
my droid unused for that period of time usually was around 80%. it was running a custom rom with 1 ghz kernel as well, so same power requirements i'd say. except epic has a bigger battery.

Battery is pretty bad with the Epic but Im not surprised at all about that. I have about 50% right now with heavy texting, a few phone calls, and listening to music. 8hrs unplugged. I think it would make it to 14-15 hrs easy with heavy use.
Phone calls kill the battery the most I believe.
And I'm using Juice Defender.

Mine was dying with heavy texting, some GPS and browsing within 6-7 hours, no phone calls....
I did a little test today.
When I'm at the police academy my phone is in my car from 1000 to 2100. My rooted 1ghz droid would be at 80% by 2100. it'd get it's regular share of texting/emails and all that I couldn't look at until 2100.
I did the same thing today with the Epic, with juice defender, it was at 79%, so pretty much exactly the same...
tomorrow I'll do the same test with JD off and see if it makes a diff

I have just installed Juice Defender (free version) and using it as installed. I'll see if it helps. I have a question about the status of TRAFFIC, it is listed as "Leave Data/WiFi enabled while >50KB/15s", what does this mean? I can guess that JD will leave the Data connection ON, even if it is scheduled OFF, if the phone is sending/receiving data at a rate greater than 50KB/15s. Is this close?
Thanks

Mine has been doing this every once in awhile. Even in a good signal area, its like the radio randomly decides to reset. I'm currently trying to see if its a software or hardware thing.

I am having the same problem with my phone suddenly. If I have multiple apps open, such as radio, browser, and facebook at the same time, it seems to cause it to reset itself. It's not a full hard reset, but more of a soft one, screen goes black and everything starts up as if the phone was just turned on.
Maybe it's time for a replacement?

WIFI impact on battery life - Tested

Leaving WIFI enabled appears to have little impact on battery life.
I have an old Motorola Cliq at my house that I charged fully, enabled WIFI, and left on my dresser for a period of time. It was NOT configured to connect to a wifi network, and often displayed a wifi notification of an open access point.
The fully-charged CLIQ managed nearly thirteen days before refusing to power on.
The additional load of enabling WIFI appears to be somewhere near 8% a day in this limited test.

Well, this is all well and good, but a cliq ain't a G2...

WIFI will actually SAVE battery power (assuming it is connected). An easy way to take advantage of this through the Y5 program that will automatically turn on/off your WIFI based on previously remembered networks. It was free last I checked.
WIFI is less battery intensive then a 3G connection.

Battery Saving Tip

Hey Guys,
Not sure if anyone has ever posted this but I thought I would share how I am able to get 2 days plus on single charge...
I only recomend this if you are not totally dependent on your email, facebook, gtalk, etc to sync.
I have my email accounts on my phone but I don't need to receive them instantly meaning they are not dire important so this works for me.
Android's biggest battery killer, which most of you probably know, is data syncing in background and just data connection in general. What I personally do is keep 3G data off at all times by going to settings->wireless and networks->mobile networks->3G Data and uncheck it.
Obviously with this off, you wont be able to connect to web, get emails, download apps, etc... But if you live in a 4G area like me, all I do every once in awhile is flip on 4G from dropdown let it sync or do what I got to do then flip 4G back off so there is no connection anymore... This will save so much of your battery but it is up to you to check things when you need to....
I hope this helps some people because it helps me a lot... I always recommend this to customers that come in my store if they are not depending on work email and such...
Let me know if you have any questions!

You can hold down the power button and click Data mode to toggle 3g

I have done those things since I've had this phone in august and everytime I talk about getting great battery life the haters come out and say well you didn't have sync on blah blah. Freaking retards. Especially if you are sleeping why not turn off sync for the email that is not going to come anyways. I haven't seen the battery life yet as I did since eclair though.

Actually my biggest killer is display. Our devices our the only ones with 90%+ battery usage for display, yet they advertised that it required 20% less battery!

I get 56 hours using Ultimate Juicedefender.

Wow...i use to get great battery life. I'm using lowest brightness setting, sfr, and ultimate juice defender and getting only like 16 to 24 hours of life.
What else are you guys doing? I use to get 50 hours but not anymore..
I thought I knew all the tricks in the book. But I use my phone constantly. Above average I would say.
Sent from my SPH-D700 using XDA Premium App

I am not sure, I keep lowest brightness and keep data off almost all day except for occasional checking but maybe 10 minutes total of data being on... I have noticed with EC05 battery life lowered even on complete stock... Most people in my store hve epics and all have suffered worse battery since the update... It didnt matter if it was OTA or OTW...
Maybe try and get a new battery...

I think the reasons the 'haters' come out is simply because you're stating your getting better battery life and then revealing you're castrating your phone. It is a smartphone after all. It's supposed to do all those things you turn off. This isn't a phone which is only supposed to make calls. I mean, if I wanted to check my email once a day, I'd simply do it while I'm in front of a computer.
I don't believe I'm one of said-haters but possibly providing a bit of information on where they're coming from as well.
I think it's well documented that Android phones pretty much suck in terms of battery life, especially when compared to Blackberry. Man, RIM got it right on that aspect.

How is that castrating your phone? I can still do everything else on the phone... You don't need a constant data connection to use it like a PDA. Do all tabs have a constant data connection? No, so are they not going to be considered PDA because they lack internet sometimes? no
I am sorry to say but if your managing your phone and doing things to better, that is not castrating, that is good device management and what should be done so it runs how you want...

Well, it sorts of like taking a porsche and not pushing it past 2nd gear. Some people are happy with it, some are not. On one hand, battery saving posts can be thought as misleading, if the premise is that you dont compromise any functionality. I prefer to charge my phone everyday and not worry about battery, but when your battery is dying when you need it in the evening, than one is of a different opinion entirely.
One thing which I realized to late, is if you are at work in the office or somewhere with wifi, you can toggle 3G off and not lose any functionality, since wifi uses a lot less juice.

I have tried I new battery, I have three that I alternate between. I have no idea what has happened to my phone. It could be the phone itself

The only reason it was posted was to try and help people who may be newer to android and needing to squish extra minutes out of their phone for the day... Or they may find themselves not near a charger and almost dead and need their phone so turn off data to preserve the battery... I mean it doesn't "cripple" your phone to turn off data... I can still play angry birds, check my calendar, call people, text, etc. You don't need your phone to have data to use its features...

Post LTE Upgrade Xoom Battery is Horrid. Any fixes?

Got my LTE upgrade done on my Xoom and now the battery is a joke. I went into settings and disabled the LTE connection, so that now 3g is only used. I also turn wifi on when at home. Currently my Xoom is draining 4ish% per hour while in standby. That means this damn thing won't last a day just sitting there, locked, with no screen on. In Honeycomb 3.0 and 3.1 I could get a days of use with 4-5 hours of screen on time and about 22-26 hours of total unplugged time. Now, under 3.2.2 my battery is totally dead after 18 hours of unplugged time with around 1-1.5 hours of screen use. This is virtually unuseable for taking notes in graduate school after work, when being close to an outlet is impossible.
Any ideas as to what's going on? Tried using Watch Dog and System Panel to see if any apps were going nuts with random CPU usage or RAM usage and everything seems to be in-check in terms of system resource usage. Considering I have 4g totally turned off and wifi enabled when I'm in range of wifi (most of the day) I don't have a clue where this power drain is coming from. Any assistance is highly appreciated given how much I rely on my Xoom for day-to-day use. 3.2.2 seems to have killed it for me.
Please help! Will try any suggestions.
Thanks.

Its not just you, mine is the same way it sucks big time. There really isn't anything that I've found to fix it.

I haven't but this isn't feasable. I use mobile internet for everything and even take notes and such on Google docs. Even though I'm near wifi for most of a given day, I shouldn't be bothered by manually turning mobile data on and off just to have power- mobile data should be mostly killed when wifi is active. That's how this Xoom worked before. A tablet without internet is nothing more than a paperweight to me. 2 classmates with LTE upgraded Xooms are having identical problems. No fixes found yet. Any other suggestions? This battery life is really, REALLY bad.
Tried going a factory reset and battery life is the same, horrid short, running nothing but stock apps.
Any other suggestions?

Same problem here, but I have the mobile network completely turned off and it still does this! Even with the switch to CDMA only!
I will keep reading this thread (only read the about half the posts before posting) so hopefully a solution will show up. But you're not alone in the horrible battery life post LTE upgrade!

I've had my Xoom back since last Wed.
No higher battery drain than previously.
I'm on wifi 90% of the time in home and office.
Yesterday I was all over north San Diego county using 4g. Got home with 60% charge which is about the same as for a prior trip with 3g.

Put your xoom back the way it was. The new hardware sucks the battery a little more. Buy a thunderbolt and then say the xoom battery life sucks. Never charged it during the day before the upgrade. Oh well, that's the price if 4g.

Download Auto Airplane Mode by DON from the market. It will help BIG TIME!! It does just what the title states, it puts the Xoom into airplane mode automatically as soon as the screen goes off. When you turn the screen back it, the data comes right back in 3 -4 seconds and you're good to go!
Also, you don't have to uncheck any settings or turn 4G off.

Update: Mobile data completely turned off, on wifi only with Xoom sitting about 4 feet from router all morning, so wifi signal was strong. This is the first time I've used the device today. Unplugged at 330am my time, its now 130pm. Device battery is at 60%. 10 hours and 40% of battery gone. That's with mobile data 100% disabled, wifi only- can't even get the Xoom to standby for a full day now. At this current drain rate, it would go from 100% to 0% in one day with no mobile data usage, no screen on time and no usage other than syncing Gmail every 2 hours.
Brother who commented above: Thunderbolt will standby for a full day with no screen on time on wifi only and it has under 1/3 the Xooms battery capacity. I should know- my wife has one and it now outlasts my Xoom. That should not be the case.
From my understanding the Xoom has two 3225ish batteries set up in a sequence. My battery life actually seems to be about half of what it was before. Is it possible that one of the two was disconnected during the LTE radio installation and not properly reconnected? Wasn't sure of the details of how the batteries were set up, but if the Xoom could function with the second battery not working, seems like that would precisely half battery life. Anyone familiar with exactly what had to be done internally to upgrade the radio? Looking at the ifixit teardown of the Xoom, the batteries cover the whole backside- looks impossible to do any internal work on this thing without removing them. Any thoughts?
Cheers,
Landon

Same here. Can't get a full day out of it. Hope a fix will be comming up.

Thunderbolt got the he-man battery and modded my otter box to fit. The xoom battery has entered the battery hog realm after the lte radio. As far as I can tell the radio is cdma/lte together. And it uses power even if wifi is on and data off. It's what I would call big brother watcher. Even if your not connected the radio is txing and rxing something. You know it's lojacked!
Sent from my ADR6400L using xda premium

Interestingly enough, removing the LTE SIM card and using wifi only made no improvement to battery life. I'm assuming the new radio is running at 100% all the time without throttling down, even if absolutely no connection exists or there is a string of faulty battery reinstalls in which only one battery is providing power. That might explain why some people seem to have greater battery issues than others.

im glad im not the only one with this problem! its pathetic! im taking my charging cable from my dock with me to work so ill have at least some battery life when i take the train home in the evenings

i to am glad that I'm not alone with this either. I use to charge mine every 4 days with no wifi on and almost no use. Now I get about a day with no use. I mainly use it for web searching and dungeon defenders when I'm home. Horrid battery life for doing nothing. Luckly I mainly only use it at home and am almost always on the dock I got from motor from the upgrade. I use about 4% an hour also with nothing on. Mine is completely stock with no root.

Yahoo mine is stock with absolutely no root or other mods. I guess they knew about the pissy battery life and that's why they gave a free dock. Lol. Still trying to find exactly what's killing the battery. LTE does drain a lot of juice but as I've stated before my wife has a Thunderbolt and per mW of battery power, the thunderbolt is more efficient and that's not saying much. It can standby for over a day with no use fine and it has roughly a little less than 1/3 the Xoom battery capacity. Something isn't right. Its not supposed to be this bad. Anyone filed a complaint/tech request with moto/Verizon? I think its something that we should all do and report what they say here. I have a feeling more and more people are gonna have this issue if they do the upgrade. Maybe if enough of us make some noise, something will be done.

Maybe it's not the radio.
3.2.2 may have some kind of interaction with something you guys were running that's causing wake locks to get stuck
Did you look at Settings:About Tablet: Battery Use ?
(tap on the histogram at the top for another, see if the time spent awake is solid or different from screen on)

I tested this on mine, with the mobile data disabled and lost about 1% battery every hour, this is on par with the performance I had pre-upgrade.

I realize it does not help you but you might look somewhere other than the wireless radio for the problem. I unplugged my upgraded Xoom yesterday morning around 8:30 AM. It is now 8:20 AM and my battery is at 66%. I was on 4G for about 2-3 hours yesterday, the rest of the time on wifi. I check and respond to my mail on the Xoom so it saw some use yesterday, though not as much as I normally do.
