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

LOL we posted at the same time, thanks for answering my question! I'll keep a backup in my glove box and one in my back pocket. This method worked great with my Hero.

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.

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.

It's under settings , location and then location setting. This does not disable the 911 location which is good.

no battery life with the 2.2 update

My battery made it to 1:00 o'clock today with the new 2.2 update that i did last night. It normally lasts till 11 - 12 at night. Whats up with that?
FYI - All the same apps,widgets, and settings
**UPDATE**
Doing a factory reset fixed the problem for me!!

Strange, I'm sitting at 75% after 5 hours off the charger and using it for moderate text usage (probably less than 80 messages today). Usually around this time it's sitting closer to 60%.

i have the .3 update and went from about 24 hours to about 8-10 hours. Battery life cut in half. My friend who has .3 is having same issue too. So much for increasing battery life.

Wow. Have you searched the forum to see if anyone else has the same issue? If not I hope it's not an isolated incident. Then again if it's isolated maybe you can get support on it better...? Good luck finding a solution.

You gave us zero information to help you. So thus, you will not get any help.
There are about a billion threads on here about battery life and how to tweak it. When you flashed 2.2 you will need to do those steps again.

yeah some people are reporting bad battery life after update. most people i know are on .3. don't know if .6 fixes this hopefully we get update soon

I did a test last night. Dropped 13% between 1130 and 3:30am With wifi on (got up cause of baby), then only 10% between 330 and 8am with wifi off. So a drop of only 23% overnight.
That's with one exchange account, one gmail account (both syncing as items arrive), htc news set to not sync, but newsdesk and feedr both syncing. Facebook for htc set to sync contacts only.

I had the same issue on all 2.2 ROMs I tried.. i am now going through the apps one at a time to see which one is the issue.
right now I am 7 hours in and sitting at 75% very light use ( read about 7 emails, 5 new articles and little to no Web surfing). installed 10s so far other than the standard with Fresh latest ROM that is.

I've actually had very good battery life, I'm running the .3 release. Battery life for me has been very comparable to running Baked Snack 9.6, with its underclocking/undervolting power save features. Moderate use of the phone for 8 hours (wifi, browsing websites here and there, one navigation route, texting, bunch of short phone calls, playing some games), my battery was around 65 or so, same as I had before for similar usage.
I did do a full wipe though, and haven't calibrated my battery since updating.

I am just stating a observation on my part. And i know all the little tricks of how to get better battery life. But like i said, before the update i was getting a full day of battery and now after the update i am getting half. With the same settings and the usage on my part.

This is not directed at you personally, but at the words you chose to use:
I am sick and tired of "tweaks and settings and cutting things off." I used them and got over 30 hours on both DamageControl and Fresh.
I paid Sprint/HTC good money for this awesome phone (and am committed to pay them a whole lot more over the course of the next 22 months).
While I can understand the 4G thing, why should I have to cut off Data-WiFi-Bluetooth, power down the CPU, not use it a lot in order to get... in short, drive it like a Toyota Prius when then phone is billed as a Maserati? Why should I have to try out this app and that app(Overclock widget, SetCPU, System Manager, Task Killer, Autostarts etc which all use battery too) in order to get the phone to do what it should have done on June 4, 2010?
Most of the battery draining apps and widgets come pre-loaded with sense (i.e. the Favorite widget, Friendstream etc). Why should I have to resort to rooting my phone or not using it in order to get the thing to last all day?
I'm keeping my EVO cause I love the device, but maybe Sprint/HTC need a little of the medicine that Jobs/Apple is getting in the form of lawsuits due to over-promising/under-delivering.
/off_my_soap_box

You should send that rant to HTC and Sprint... I think we all stand behind you on that one.

there are lots of reasons a battery might not last. there are way to many tweaks out there which is why you have to do it yourself.
First set the phone up like you normally have it and test the battery life. if you can live with it your good. if not start looking at the settings. Read the tweaks but don't just take them as golden as everyone is different and uses their phone different. Ask yourself if you real need that setting. (I like my screen time out at 2 min. do I need it NO 1 min is fine). When done with the settings move to the apps. load the flat ROM no apps and run for a hour and track your battery life. then add the apps 1 at a time or in small groups and let run an hour and track. there are was if find what apps are using the CPU or Battery but many do this normally and yet don't effect the battery much. Only way i have found is old school add them one at a time. When you find a bad one decide if you need it or can find a replacement.
I am done with Sense as Launcher Pro Plus is awesome and now with the only Widget I was missing (Calendar). Once I done going through my app list I will create a new thread in General to list the bad application I found unless someone else has or does before I done that is.

From what I have gathered from using .3 that apps auto sync/update on their own now with "always on mobile data" turned off. if you use advanced task killer, do a kill of all apps then turn the screen off. If you wait for a few minutes and turn the screen back on you will notice that apps like news, messages, Twitter, Facebook clock, weather and others will be active. From what I gather the decrease in battery life is from apps like those will send/receive data on 2.2 while on 2.1 apps would not update/sync until you manually refreshed or opened the app, as long as you didn't have "always on mobile data" enabled.
Edit: this reason is why I uninstalled fring. Just too bad I cannot uninstalled qik.

It is a mini-computer. You don't use it like a "phone" anymore. You shouldn't expect more than 15-20 hours on it. Do you get angry when your laptop runs out of life after 5-6 hours? If you don't want to do tweaks, then don't. Keep a micro-USB at your desk at work and charge it there. I, myself, enjoy rooting so I don't mind tweaking it. I also get 30 hours of life on it due to this. If you don't like to do that, you get what you put into it.

Again, you have unrealistic expectations for a smart phone it seems. All I have is Set CPU running on my phone with Fresh 3.0.1 and works just fine. I still use my phone like a "Maserati", it just lowers the CPU when the screen is powered off. That is like saying you want your car to idle when you get home at night until the next morning. It doesn't change how you drive it, just how you store it in the garage.

You don't have to use them though. You can remove friendstream and go with either the twitter or FB update app or go without either and just check facebook like anyone else. As far as favorites go, you don't have to use that either. You can just make shortcuts to each person's phone number on that same screen if you think that is sucking all your battery life. There are always other options or fixes, but again you expect the phone to come out of the box perfect without any customization. You are getting away from what Android really is. Something tells me the Iphone would have been more your liking since it is built around lack of true customization. This isn't a rip, but just saying if you want cookie cutter phone reliability, it is hard to beat Apple. If you want the ability to tinker with the phone, the power to change things, and the power to make your phone yours, then that is more Android.

I can understand your frustration, but nothing was ever promised to us on purchase. I don't remember anywhere seeing something saying the battery would last 30+ hours out of the box. Apple had an actual structural issue with their phone, that is why they had the lawsuits and PR nightmare. This is just the phone doing what most would probably expect(at least anyone who had a G1 or Hero or any of the earlier Android phones). You love the device enough to keep it even with your frustration, something tells me it works quite well for you. But I have yet to see any over-promising/under-delivering on the Evo myself.
And no, I don't work for Sprint or HTC. And no offense meant to you as a person, just I didn't understand your motives on your frustration. Guess we will have different opinions on the Evo so far.

I had the same battery problem after updating to 2.2. After 3 hours my battery was at 50%. Normally it'd be at 50% after 9 to 10 hours of usage.
I did find that some settings had been reset. Once I turned off all the crap syncing, gtalk logging in, Sprint Zone, etc my battery usage has seemed to flatten out.
I made it an hour and only dropped 2% which is much more like it. This is all with very little usage going on.

Buy a new battery! Best solution!
No joda!

very funny just pluged my phone in using flipz newest after 19 hours
make sure you are signed out of googletalk !!

If you're having battery problems..

I feel bad for you son, cause I got 99 problems but battery life ain't 1!
Seriously. I don't know what all this whine about battery life is about. I am running stock 2.2 unrooted. All I did was change a few settings on my phone and I get battery life to last 1-2 full days with normal use. With heavy usage, I get only about 15 hours.
All I did to achieve this was
* Turn of background data
* Lower the screen time out to 30 seconds
* Lower the contrast of my display
* Synching Gmail (push notifications) and Weather (every 6 hours), disabling news, stocks, twitter/facebook (I don't use any of that stuff)
* Keep Wifi, BT, and GPS off, mostly because I do not need them.
I personally don't use facebook/twitter all that much and really don't have a desire to be updated when my friends change their status. But either way, my configuration works for me. And, I am not sacrificing any features (that I use) to achieve my setup.
I don't know. I read all the little battery dances to do to squeeze out more battery life. I've tried them, but frankly I see little if any difference in my battery life if I do that. The phone uses a lot of battery, yes. But, it is also more powerful than the desktop computer I was using two years ago. Hell, it is more powerful than the laptop computer I was using four years ago. And today, I have it in the palm of my hand.
We cannot expect to get the same battery lives out of our EVOs as we did from an old school Nokia. The fact is this phone just does "more". My previous phone was a Palm Treo Pro. That phone literally did crap, and I still had to charge it almost nightly.
Just sayin'.

I agree, I actually managed to get 54 hours out of my Evo with light use and I thought that was impressive, sure I can probably kill it in 5 or 6 hours if I use it non stop but I have yet to need to charge it at work because I can't ever find the time to play on my phone all day.

who cares that you have a limited dumbed down phone that can run days on end blah!!! This device is obviously meant to be user connected. We shouldnt have to shell out money and then limit ourselves to certain **** just to conserve battery!!! htc is even dumber for making the charge software charge to a set 1500mah or whatever the specs of the stock battery is #fail #facepalm
lol
not to mention...we didnt pay $200 plus for a device and $10 a month for nothing.
can we compare that to buying a cadillac or a mercedes with no leather seats? or how about those new modern muscle cars like a charger/challenger without the hemi hehee

Best radio signal to use? (battery life)

I can use *#*#4636#*#* and I read somewhere that it can help with battery life if I set a certain antenna from there? I forgot where I read it though, if someone can please let me know that would be great. There are NO rogue apps running, I only have about 10 installed.
The phone is 4 days old, so it could be why but I've battery cycled it twice already (letting it run dead and recharging it for 10 hours). All my widgets are off except weather and that is set to update every 3 hours and it is NOT using GPS. Wifi is off, so is bluetooth. Gps is off as well.
Is anyone using maximum power saver or just the regular nighttime setting for those reporting better battery life? I also uninstalled launcher pro, it seemed to glitch my phone a lot with the google toolbar and also seemed to have a slightly bigger toll on my battery. Also battery health is stating "Good". Is that the best or does it still need more conditioning?

You probably shouldn't change things in there. Look elsewhere to conserve battery.
You didn't note what your battery life is like either. But you should still let the battery charge and drain a few more times before trying to squeak out more battery life by modifying something like this....

Well I'll give you an example. The phone was unplugged almost 6 hours yesterday, and I used it around 3 hours and 46 minutes max. It got down to 5 percent and shut off. I had my music i was listening to for 25 minutes. I had my IM program on for about an hour, had a 12 minute phone call. Was texting back and forth mainly, and I checked a few things on the browser and exited out. MY IM program uses GPS to get my location but only when I request to do so, then shut the gps off. I force closed it when I was done to be sure it wasn't gonna drain any more of my battery. My notifications are off mainly except for my texts and such. And this was with JuiceDefender on the last half of the battery.

I don't like programs like Juice Defender to be honest. They usually go buggy and drain the battery more than it saves. People just get excited and leave positive reviews.
I'd honestly reset to factory settings in case there was a one-off glitch. Set things up again and use it like you would normally to gauges things. My battery lasted over 40 hours from the first charge.
With results that bad, I wouldn't troubleshoot beyond resetting it. Take it back if that's the case. That's not right. And it's not worth your time.

That code just pushes your phone to use EDGE only and not 3G. It can increase battery life if your phone is constantly trying to hold on to a spotty 3G signal, which can be common .

So theres no need to flash to stock / reroot / all that jazz I did when going from eclair to froyo? Haha.

Not unless you wanna update the modem. You could flash the new EL30.tar with odin, flash cwm5, then flash cm9 in cwm5.

Sounds easy enough, Is EL30 modem a big improvement over EH17?
Also hows the every-day-usage capability of CM9?

Not bad at all for an Alpha only a few weeks old for us. Minor bugs that not everyone experiences. A lot of us are using it as a daily. Battery life is not good because it uses a lot of resources. It was meant to run on phones with twice the RAM.

Cm9 runs good. Battery life was a deal breaker for me and it was a bit sluggish. I just barely came from srf 1.2 ef02 genocide 2.0 myself (which was rock solid and superfast).
I settled on gleangb for now.

Battery life is decent enough for my tastes. The only bugs I'm experiencing now is some tearing in video playback and some minor artifacts in video recording (sometimes). Other than that it's pretty rock solid imo.

Battery life for me is very good on ics. But its not my primary running OS due to its bugs.

Please stop talking about things that you don't understand. Battery life has little to do with the RAM usage. CM9 alpha4 for me is easily goes 28 hours battery life with a 1.5 year old original 1500mah Epic battery. The trick is to prevent wakelocks, I'm usually ~90% in deep sleep. I disable LED notifications, all haptic feedback, notifications for anything that uses push data (Facebook, gmail, email, etc.) I get an extra ~8 hours battery life if I use Juice Defender to turn off 3G data and Wifi when the screen is off. It takes a little delay for data to start again, but that is acceptable to me. If all my push data notifications are turned off anyway, why bother having data enabled at all?
If someone really needs to contact me they can SMS or Call, which causes both vibrate and sound. Otherwise I'll see messages when I too often turn on the phone screen.

Pretty much my exact same setup, I got tired of using Juice Defender because of the lag to start data back up but when I was using it I was getting around 33 hours. I don't use my phone much except for calls and sms so this works fine for me.
Also, I remember you SemiGamer!

I really respect you and all that you do for us but with all due respect, using your phone for more than just a phone on CM9 eats up the battery pretty quickly. Browsing XDA, polling 4 business email accounts, or on the web uses about 50% more battery than it did on CM7. It was mentioned at initial release how it was meant to run on phones with twice the RAM which attributes to it's sluggishness and lower battery life. I know each Alpha just gets better and better and that is awesome but it will be a while if at all that it can compete with something like CM7 for battery life. I am sure with the same setup you have you can get 50% more battery life on CM7.

Agreed I pulled 5 hours of display on cm7 and can't hardly pull 2h 45m on cm9 same setup no wakelocks no sync browsing xda undervolting as far as my phone will handle..nothing helps. Had to get a 3500mah to compensate the gigantic battery usage and am lucky to 5h45m on it over 13hrs uptime. However we all use our phones differently and to you @wtogami you may see no difference, however for others it drops like a rock.
Anyways semigamer how'd it go?

Yeah if you just stare at your phone while the screen is off and dont do anything haha. But even still with my stock battery haha not even 6 to 7 hours it would be dead. with a 3500 it last longer but its not worth it right now.
Once CM9 progresses to CM7 state then it might be worth it. Still ICS requires more ram so yeah your battery is going to die faster because of memory swapping. IDC what anyone says ICS on our phones still would not last as long as GB.

Plus there was no reason to be rude about. I may not be a DEV but I know how Android works with resource swapping and memory clearing.

Exactly i don't understand why everyone starts retaliate and then the only way to reply is retaliating back, if not then they pass on by. Its so frustrating

Hi, I noticed ics charges faster.

I absolutely love when people who don't build the ****, don't know how to, and couldn't possibly in fine detail explain how it functions argue with the people who do. Cause they like, know better. I'd say if one of the EpicCmTeam says the RAM shortage isn't the cause of the excessive battery drain, he's probably right, as he works directly with providing us with the build, on a level none of us understand or have skill in. Kinda like how certain people wanna argue that they know better than a google engineer. That clearing batterystats does in fact change your battery life despite very explicit explanation from said engineer dictating how that file holds nothing more than the statistics displayed to you about your battery under settings.

Welp I'll stay out of you guy's debate for now.. Lol.
Thank to everyone that helped me with my OP, Got eveything up and running real easily.
One question left, does Voicemail work with CM9? Not getting any voicemails even though I'm told some ppl left me some. Any way to get Visual Voicemail to work?
(Know someone prolly asked / found a fix already, sorry for taking the lazy way out)

C'mon this type of criticism isn't appropriate.
