Today I decided to do a real world test of the Evo's battery life. I used my phone the way I would normally use it on an other day. As for the phone itself, I am running the rom from the OTA update. The only changes that have been made is that I am using unrevoked root method so that I can use the Overclock Widget (marketplace) to turn the processor freq down to 245000 when the screen is off. I also use Advanced Task Killer to turn off apps that I am not using. I had bluetooth and gps turned on throughout the entirety of this test, wifi was on for about 3.5 hours. During this test I played a game for a short period of time, did some light web browsing, and had several phone conversations that totalled a little more than 2 hours. With doing all this, my battery lasted for a little more than 11 hours. That being said, under normal use the Evo should definitely last you throughout a full day.
Thanks for the info. I got my Evo yesterday and haven't been able to put it to through extreme testing yet
No problem. just kind of got tired of hearing how poor the battery life was. Even before using the overclock widget I was still getting decent battery life, but the overclock widget just put it over the top. To add to that, I don't normally talk for 2 hrs. on my phone during a normal day, so really a lot of that 29% battery drain from phone use wouldn't be there. The only thing I didn't use today was 4g (which I don't normally use unless I'm on the phone and need to use data).
Not sure what this proves or "dispells". When people (myself included until making some friendstream changes) are getting 6 hours out of a charge with light use, that is a real problem. You must not have friendstream syncing...if you did and did everything you just wrote about, your phone would be dead in 3 hours tops. Thanks for the info., but once again, people are havnig real issues with the battery...it's not made up.

If you are experiencing poor battery life then it is most likely attributed to not managing your apps properly (friendstream included). For example, without advanced task killer you will get a drastically different amount of battery life than if you have it. Then add to that, the way you configure advanced task killer can add a large amount of battery life compared to having advanced task killer without it being configured properly. Even with friendstream running you should still be able to get a decent amount of battery life (I am aware that it does use more juice), try having your facebook sync less often.

I totally agree I've been using my evo and been fine, I only really have it connected to power when I have it tethering. Besides that it lasts me not all day but while I'm at work (which is the most important part) I get a good 9-10 hours out of it before I really need to charge. It should also be noted that I use locale to switch BT and wifi off when I'm not in an area to take advantage of them.
I think some people have bad batterys/evo's, it's not just a matter of running the right programs or killing tasks

While that is possible I think the majority of the problem rests with the user's mismanagement of apps. I have seen way to many posts from people declaring the battery life to be so horrible, only to make a few changes and then turn around and say how much better it got. If that person had a bad battery then the battery would still have been bad, it wouldn't just start being good. That said, it is very possible that there are people with bad batteries. I just think that most of the people have good batteries and bad phone management.
I did pretty much the same thing. I have the O/C widget to set the frequency to 245000 when the screen is off and also have Advance Task Manager configured to close apps I'm not using. Helps out a lot and I usually get around 12~14 hours on a charge.

While I completely understand what you are saying, I can't really agree that b/c someone is not getting a full day out of their phone it is b/c of poor app management. While deleting facebook for sense, then reinstalling with only contacts synced fixed everything for me, the fact that you have to go through the phone with a fine tooth comb to get it to run more than 6 hours at a time is pretty silly. While doing that stuff is fine for me and most on this forum, it will undoubtedly turn a lot of non-techie people off from this phone...especially with Sprint doing their new 30 day full refund policy.
It's all good though, just plugged my phone in after 19 hours...playing with it most of the day.
I use advanced task killer and turned off sync for apps I dont use. At 65% used pandora (in 4g for about an hour), browsed several sites, made phone calls, text, emailed. All the normal stuff. Took my phone off the charger 15 hours ago.
Prior to using advanced task killer I would be to about 18% right now. So for those saying that task managers kill more battery power my phone seems to do the exact opposite.

Task killers really only help if you have an app that would normally be giving you higher than usual wake time (the calendar comes to mind). At the start of every boot I always make sure to kill everything so only essential apps and those I use are running. I don't use any kind of auto kill.

It is no longer recommended that a task killer be used. It may result in poor phone performance.
After i rooted with Toasts method, installed OMJ's rom removing all of the sprintware and added the OverClockWidget to tweak the processor, i was able to go a full 32 hours without charging. i had gps and bluetooth on the whole time and wifi on for several hours. i made calls, sent texts, took pictures, basically normal usage.
Just to add to all this. Bad battery isnt just a HTC Evo problem. Go read the forums of almost every android phone released and they all report the same things (in the beginning). Someone that has had a android phone in the past probably hasnt said much about battery. There are so many things you can do to increase battery.
1. manage your apps. Exit them instead of leaving them running (press back button until the app closes, or some apps you can Menu> exit) Pressing home doesnt close the app, it only takes you to the homescreen. Also change the sync times of all your apps/widgets. If you dont use gmail or google calendar, then uncheck the "sync" in Menu>accounts & sync> google. One last thing use a task manager (not recommended by some devs) I use it to end tasks of apps that use data, or ones that i use maybe once a day or once a week, i dont need them cached for quick returning, so i end the task all together. I ignore apps so they dont end that i use very frequently or ones that dont use data or run in the background.
2. Calibrate your battery once like so.. Charge your phone to 100% and then use your phone like normal until its so dead it shuts off by itself. Dont plug it into the computer or wall charger in that time. Then once it shuts off, plug the phone into a wall charger and charge it till its 100% again. After that, plug and play as much as you want.
3. Buy a car charger, usb cord for the comp, and maybe another wall charger. Buy an extra battery or extended battery. Doing the above and adding these to them, youll have a huge increase in battery.
I have an htc hero and i can get well over 12 hours of use by just watching what syncs and what uses data. And i use my phone alot, and wake it up a ton to check for notifications.
I use a friends Evo so im not new to the device and I understand its a different phone.
Stock htc phones come with a lot of stuff preinstalled and widgets. When signing into them with your accounts the sync times are usually pretty high, some like every 15mins. Watch what you are doing with the phone and youll have normal battery life.
i avg 18 -19 hours per charge so im very happy
aaaaah ok now I know who is the idiot Dylan here. Thanks. What a dumbass know-it-all.
I think some people are getting poor battery life because intermittent signal. I know this was the case for me. When I go to a friends house that I barely have signal, the phone constantly tries to find signal or goes into roaming. It would drain the battery fast. When I was in good signal area it seemed to last quite a while. Just saying that it is more than just running apps that cause poor battery.
Also if you will not use the internet turn off the mobile network, put the widget in your screen. You can receive calls but the internet is off.

You make a very good point. Weak/no signal areas will drain your battery (as with any phone) very quickly due to the phone constantly scanning for signal. Not really much you can due about that other than turning your phone radio off or switching carriers lol. One thing I've read in the Dev forum that may help you is to change your prl to the Alltell/Verizon prl. Some people have reported that this works well in low signal areas.
I've had the HTC Aria for about four days now and my biggest issues is the battery drains to quickly. At first I attributed it to use because android phones prompt you to use them more often. However, even without use it still drains pretty rapidly. Does anyone know of a solution to this issue software wise. I have already turned off Bluetooth, GPS and Wifi. Are there other solutions
I got mine on Saturday, and I've actually gotten pretty good battery life out of it. I'm still in the habit of charging it every night, like I had to do with my old WinMo phone, but I think I could probably go two days without a charge. And that's with GPS / data always on, Wifi parts of the day, and pretty heavy use, since I'm always playing with it.
Have you tried something like Advanced Task Killer to keep apps closed that you aren't using? You can also adjust your screen brightness and timeout to try and save power.
It says that of my power is used by cellular idle or something like that 50% of it was used by that. Could it be my AT&T service
I don't get more than 10 hours out of mine. When I know I will be out all day, I turn the screen brightness almost all the way down to help conserve energy.
Good as it Gets.
With basic usage (some texting, a few calls and some market browsing or playing a game here and there) about 2 to 2.5 days without charging. Maybe the ones having issues with there phone sucking battery have to many widgets running.
In my current configuration I am only using 3 of my screens and only 3 widgets [favorites (small one), HTC clock/weather widget, and the HTC calendar widget (small)]. I have my work email checking every 30 minutes for syncing. I also have gmail and the default mail app pulling mail. I run ATK but only to kill apps on startup (cause it runs almost everything), other than that you don't need a task killer as you will have to reload these tasks next time and that will drain battery. I don't use it after that to kill anything. I am also running my screen at about 30% brightness.
Just some tips, widgets are nice, but they suck the battery life as well as constant updates. Check to see what you are running and disable/remove what is not needed or adjust sync times.
My battery life is fine. I got two days over the weekend with light usage. You need to look at what services are running and disable any widgets that you dont need. You may also want to look at the sync settings and turn off things you dont use (such as news). You do not need a task killer.
Also, see this post:
cranked said:
some quick tips:
1) disable market notifications - Market -> Downloads -> Notifications -> 'Don't Notify Me
2) Lower the sync times for your social network apps like twitter and facebook (or make them manual)
If you still suffer, have a look at some of the great tips HERE on the Cyanogenmod forums...ignore 1 and 3.

Also one might do *#*#4636#*#* then change phone setting from WCDMA to GSM .... Then that get little more out of battery...
It's critical that you turn off auto-sync; I have found that it absolutely destroys battery life.
Before I was losing maybe 5-10% every hour on standby, but ever since turning off auto-sync, I'm still sitting at 100% battery after 5 hours of standby.
Turning off mobile data/Wi-Fi doesn't make an impact on battery life, in my experience.

I edited your response..
Auto-Sync in itself is not going to be a problem.. Depends on what's syncing. EVERYONE will have different battery life because everyone uses their phones differently. Different configurations, different accounts used, different amounts of traffic on those accounts, not to mention actual usage patterns.

90% of people will have *slightly* different battery life.
5% of people will drain it fast.
5% will use it like a voice phone and might even get 16 hrs out of it.
But to turn off all apps makes for an invalid test because then you're testing the phone as if it were a non-smartphone, like a voice only phone.
I think the battery is too small for me and probably too small for most people. I look forward to fat batteries for this great phone.

My wife gets 2+ days out of hers... The battery is not that much smaller than my Nexus One, a more powerful phone, and I'm a power user with a lot of crap running including IMAP push mail, weather syncing... I look in at Market, Facebook, Twitter and manually sync those types of things etc.. I can easily get a full day out of it, off charger ~8am back on the charger midnight, 20-30% left. What I don't do is sit staring at my phone all day or play games for 8 hours at work, nor do I use it as a mp3 player..
How much battery life are you guys getting on your Tab Pro 8.4? I bought mine couple of days back and I felt it's disappointing.

What bugged me was the disappointing battery life when the screen was turned off (not completely powered off of course). Even in airplane mode it would die in a day or two just sitting around. Battery stats showed Android System and OS were killing the battery. I never figured out if there was a setting or something to fix it.
Instead I loaded Cyanogenmod 11 on it a week ago and now it uses only 3% of the battery a day when I'm not using it. I don't miss any of the Samsung extras.

Something must be keeping it awake. My tab has excellent standby battery life.
Doesnt lose more than 5% in a day. I do have the setting to turn wifi off when in sleep mode though (unless plugged in)
Battery life on the whole varies. Video watching through the stock video player drops about 10% an hour. Surfing would depend on your browsing habits. Gaming drains close to 20% an hour. Pretty standard. That along with the excellent stand by time means I get about 2 days of use on a charge.
Every day at work telephony, internet, email, IMO 24hours, 24hours Bluethooth Gear 2 connect. Dinner consists of my tablet battery 55%. For me life is great. My tablet root and frozen Samsung Apps (Bloatware) ... XDA .... Try the Nova launcher from the Play Store to Improve speed. Set it as your default launcher then Disable / Turn Off;
Flipboard, MagazineWidget, S Voice, Samsung Apps, Samsung Apps Widget, SapaMonitor, Screen Saver, World Clock, and (Hancom, Office for Android Share, Hcell, Hshow, Hword, Updater, Viewer Launcher, and Widget) if you do not plan on using it.
We will be adding Quadrant test 24,000 points on the original ROM.
Play google baterry doctor.
Battery life is good its an app thats draining the battery.

Yes it was using as much battery as watching a movie with the screen on. Something was terribly wrong with it. I think this behavior started after a software update I got from Samsung.
I turned everything off including Wifi and it was still eating the battery while sitting there with the screen off. I have never seen that with any Android device I've ever owned.
But I'm happy with Cyanogenmod. Battery life is outstanding now.
My battery life was mediocre, and then I put cyanogenmod on, and it went to dreadful. With the tablet at 100% and OFF, untouched, it would be 20% down in 10 hours. In contrast, my iPad loses maybe 3% in that time, doing the same thing - tracking email.
I ran a wakelock tracker and noticed that Exchange Services has it awake about half the time. The total time. Like in 10 hours Exchange had it awake (with screen off) more than five hours. Effen ay. Something is seriously screwed up with how Cyanogenmod's Exchange talks to the two Exchange services I use. Switching from Push to "5 minutes" has helped significantly; Exchange is still the worst culprit, but now only by a factor of four rather than a few hundred.
Ideally what I'd like is the new Exchange apks modified to prevent admin and fixed to be less wakelock intensive.

Cyanogenmod has their own version of Exchange?
Our Exchange servers at work are ridiculously slow and unreliable. They can take two minutes to return your mail which is a major drain on your battery if it's set to check it every five minutes and you get a lot of mail. Sometimes they'll just stop responding and leave you hanging. The IT people just tell you to keep trying and you'll get your mail eventually.

Dunno.. 7-8 hrs I guess. Screen on time really doesnt mean much without any context.
I can get 12hrs+ watching videos on 20% brightness. I can kill it in 4 hrs playing games at 100%.
Like I said, the standby is excellent. Drains less than 10% in 2 days. So for me, I have about 90% to use over 2 days.. and from my experience,
video drains less than 10%/hr
gaming ~20%
reading books drains less than video.
General surfing, mails, social networking uses between 10-15% depending on how you are using it.
My brightness is usually around 40%. Goes up rarely when I'm using it bright conditions. Goes lower when I'm reading late at night
Should give you an indication of what you can expect from the battery depending on your usage..
Mine drains about 10% per hour while constantly using the device for light tasks, such as reading, web surfing, and watching some YT videos here and there. That increases to about 15%/hour when I watch movies. So after watching a 2 hour movie, I expect to see about 70-75% of battery left. Now if I'm listening to music for an hour at the gym with the screen turned off, it only drains about 3%.
At first, I thought that was pretty mediocre and felt disappointed. But I've taken my tablet with me on many trips and never had it die (usually just close to 20%). I rarely ever use my external battery pack. I know this will vary depending on how long the trip is and how much you're using it, but I'm just saying that it meets my needs despite having a lower battery life compared to some other tablets. I do all I can to extend it, but I don't have to constantly watch it.
Last night I charged the tab 100% and with Wifi off (sync for 1 min every hour. )
Today the battery is at 71% - On battery 13hours - 44 mins
27% Android OS
24% Google services
13% Android System
8% Onscreen time - 20 mins
Should I flash CM to fix this?

CM won't fix that. Install Better Battery Stats or Wakelock Detector to nail down the precise problem. If you're using them, it could be Exchange Services or Google Drive (yeah, that turkey wakelocked me to oblivion!), at which point you at least know what to attack.
You can find BB on XDA here and WakeLock Detector on XDA here, both are also in the Play Store.

Google search with 23 mins of wake time and Gmail with 6 mins.
Currently Deep sleep is 14 hr 26 mins. Total time is 17h 5m. Awake is 2h 39m. Screen on time - 27mins.
I added the google now widget a couple of weeks back and that caused some wakelocks and overnight battery drain. Removed it and didn't have the problem.
The battery life is pretty good for me. Was out a lot, so had wifi off for large parts.. watched videos (from device), read some books, played some Asphalt (not much.. around 30 mins) and some browsing/mails..
Got 11 hrs screen on over 2.5 days and still have 15% left.
Yeah was indoors so the brightness was never over a third (~30%) and reading books really doesnt drain much battery(especially if its at night and you turn the brightness further down)..
I'm not saying people will get 10+hrs screen on with their device and usage constantly.. 8hrs would be realistic.. but the point is, the battery is a lot better than I had originally expected.

I have this same problem - except my GTP is 100% stock, unrooted. I can go into Settings/Battery to see that Exchange Services is chewing my battery. It will die in less than 24 hours, even if I don't use it - as long as it has a WiFi connection. I think if I turn off WiFi, it will stop attempting to sync and the battery will last "normally". I don't know for sure, though, as I haven't tried. I'm not interested in a tablet with no network connection or even without my email.
I'm going to cut a VERY long story short (at least, here) and say that I have spent several hours logging the ActiveSync traffic between my tab and my server, poring over the logs, and I have identified the problem. It's one particular item that is failing to sync, which causes the tablet to retry the sync every 1 second. The sync failure causes the server to log an internal server exception every time - despite the ActiveSync requests from the tablet being correct. I also found a Microsoft KB article that appears to address this exact problem, and MS has a hotfix available for it.
I have talked to Tech Support at my hosted Exchange provider and they have confirmed with their operations staff that my server does not have the MS patch that is referenced in the KB article installed. Unfortunately, they are giving me a bit of the runaround on installing it. I only have one mailbox hosted with them, so I have no pull. They sound like Verizon. "We have to thoroughly test this update in our lab before we can install it on your server." And "nobody else has reported this problem and we can't put too much time into a problem that only one user is experiencing."
So, I am now just waiting for them to install it on my Exchange server and see if it really does fix the problem for me. If it does, I will be posting about it on XDA and the AC forums, as a Google search showed me that a lot of people, with a lot of different Android devices, have this same problem and nobody seems to know what's really going on or how to fix it. I will try to remember to post back in the GTP General subforum specifically, too, so stay tuned.
My battery life seems to be getting better as the battery gets some more charges on it.
Sounds basic / silly, but i simply put mine in battery saver mode and that made a big difference with little effect on performance
I got my new S7 Edge from TMobile last Friday and sent back my iPhone 6+. So far I find the battery life to be complete ****e. I did all the normal things I would with any phone like turning off notifications for everything, turning off auto brightness and setting it low, turned off background usage for everything, enabled no background data, turned off animations, installed nova launcher and a few other things.
For example; I unplugged my phone about 1:30 ago and only played music in my car for about 15 minutes.. my battery is at 80% now. If I actually use the phone I can watch the percentage trickle down by 1 about every 30 seconds. Thats just with browsing the web... If I'm in a game it drops 2% at a time extremely quickly. Maybe I dont understand how it works yet, but I closed all of the open programs and when I go into Application Manager i'm able to "force close" all this stuff. Shouldn't that option be greyed out if I closed all the open apps by pressing the left button? I also installed advanced task manager and used the widget to close open things. It tells me it closes a number of tasks, but they still are able to be "force closed".
This phone is unusable in it's current state. I talked to TMobile chat and after some basic troubleshooting I was told to call, which I will be doing later. So is anyone else having extreme drain like this with nothing open? Also am I not correctly understanding how apps run on Android? I've searched the internet and read a lot of articles on these things and I feel like I understand it somewhat. The features and screen of this phone are a million times better than my iPhone, so i really don't want to switch back. Thanks
TL;DR - Battery drains 20-30% an hour with minimal, sleep usage. Apps stay open after closing. SOS Plz halp
I read in a post that people are having big battery drain because of media scanner service scanning the SD card constantly. I have a 64gb SD card in so this could be it.
Hmm, I have the T-Mobile version as well, and have an SD card inserted. I'm not having any battery drain issues, knock on wood. Took my phone off the charger at 9:30 a.m., it's now 1:30 p.m. and I have 84% left. I've done some texting, some WhatsApp, some Trivia Crack, a couple of phone calls, answered an email or two, did a little browsing in Chrome, and some Snapchat. I also have always-on display turned on.
Not quite as stellar as the battery life on some of my Nokia Lumias, but pretty darn solid, and definitely bests any battery life I've witnessed on Android or iOS.
I don't know all the details of your usage, but it's not like it's complicated so I doubt you're doing anything crazy. I'd bet the issue is either a bad device, or something really simple we're not noticing. Either way, I'd definitely exchange the device while you're in the grace period.
If it's at all relevant, I have the gold variant. I have a co-worker with the black one (also T-Mobile) and seems quite happy with his as well.
That's a really abnormal drain. It sounds like you might have a lemon. I would recommend getting it replaced or backing it up with Smart Switch for PC and doing a hard reset. Sometimes the store reps are helpful with finding battery-draining apps. Sometimes.
I thought it might be bad also. I don't think i could have changed anything that would cause this. I also have Always On Device turned off, anything like that is off... even edge screen features and ones that do something when you move the phone. When I get home im gonna factory reset it and see if its any better. If not I will call TMobile and request a new one.
Yeah, you likely got one with a defective battery. I don't think I could get mine down to 80% from fully charged that fast if I tried.
Yeah you shouldn't be able to lol. Do you know what I was talking about with the apps staying active?
So I did a factory restore last night and left my phone off of the charger overnight. It only dropped by 2% over 8 hours. In the past 2 hours it has only gotten down to 90% even with me downloading all of my apps again. I think the issue is resolved. I'll keep messing with it and see if it's really fixed, but I'm also not getting the SD card notification constantly anymore.
Hey all,
One of the things I've noticed since first using android on the original galaxy S (Sprint / Evo and Epic 4G) is that android seems to lag super hard after about 6-12 months. This also seems to coincide with crazy battery drain. The problem is that this doesn't seem to be hardware or even OS version-specific. It's happened on every single one of my android phones since 2010. Every year i get a new phone and think that it'll be different this time, but every year the lag and battery drain appears again after around 6 months of use. When I do a hard reset it's solid and responsive for around 6 months again, then the lag and battery drain comes back.
Specifically, the lag is the type where you hit the home button or open the google search app and it takes between 2 and 15 seconds to actually open. This is especially bad when using google maps in the car. The phone sometimes takes upward of 10 seconds to respond to things unless i reboot and force close all apps (and then the lag comes back after an hour or so).
The battery drain is where I regularly drain 40-90% of my battery life within 3 hours, sometimes with minimal screen on time. Most recently, I had my phone screen off for 3 straight hours on wifi with bluetooth and GPS on and battery drain was about 7-8% per hour. A look at the battery stats often reveals that top battery drain processes include, "Android System," "Android OS," "Google Play Services," "Phone Idle," and "Screen."
The only thing consistent since 2010 is the use of an SD card and some of the apps I have installed. I've removed the SD card and it still lags though, so I'm thinking it's probably a rogue app? The thing is, when you go to battery stats, there aren't really any high-cpu-usage apps there that would explain either the high battery drain or the lag. And I dont think Android N allows us to track CPU usage of individual apps, so I cant even use a battery stats app to figure out what's hogging the CPU.
Anyone else have any experience with this? Any ideas would be super helpful. Thanks.

Hi. I'm currently looking into this with my V20 H910. I've had decent battery life on my phone until a few months ago. The past few weeks I'm charging my phone about 3 times a day because of the battery drain. I disabled auto-sync, uninstalled some pull-type apps but nothing helps. I've charged my phone to 85% (recommendation for battery life according to accubattery app) and when I wake up the phone is completely dead. During the day I'll have it next to me with the display off and I'll lose around 50% battery in a couple hours.
If anyone out there can help I'd / we'd appreciate it!!!
Going to move this thread to the V20 Q/A section so hopefully you guys get some more help. I have a V20 myself and don't have these issues.

The best app in the world to figure out battery drain exists thanks to one of the members here who has been banging away at it for over seven years.
It's called better battery stats. This is the only app that gives you half a chance of figuring out where the drain is occurring.
You've been on XDA since 2007 ? high time you check it out

Battery stats in android is a toy, it tells you very little.
I had my phone screen off for 3 straight hours on wifi with bluetooth and GPS on and battery drain was about 7-8% per hour.

The drain is high but why did you have GPS on with the screen off. See, its hard to tell if that is normal or not depending on what GPS was doing.
What's your drain like with screen off, on wifi & bluetooth and no GPS
