HTC EVO 4G :: Shooting For 50 Hours Battery Life
Jun 12, 2010
Update:
40 hours and it finally died!!
36 hours and 16%!!
33 hours and 27%
28 hours and 48% I'm rooted (unrevoked) BUT I'm not running this over/under-clocking widget, nor do I run ATK or any other task killer! In fact, here's some of my pertinent settings:
- Disabled 4G (can't get it where I live anyways)
- WiFi HotSpot (android-wifi-tether) is obviously OFF most of the time
- WiFi is ON, weak signal to boot (AP in back of house)
- BlueTooth is ON, but not active/paired
- GPS is ON
- HTC Weather/Time Widget is on
- Turned off FriendStream widget
- Not running any silly MySpace/FaceBook/Twitter widgets
- Push Email (ActiveSync from Exchange, average about 100 emails and 5 appts per day)
- Calendar alerts were on vibrate most of the past 2 days but I turned that off as I don't need it
- Also have K-9 running IMAP with a 5 min poll
- I use speakerphone at least 50% of the time, and I had about 30 calls over the past 2 days
- I've installed a bunch of apps, but nothing to manage the system/cpu
- I'm running a pre-alpha of the security/anti-malware software I'm building
- All of the Sprint/factory/HTC apps continue to run, but I seldom use them
- I turned of all haptic feedback (uses vibrate) but phone/sms still vibrate
- All other settings are factory, I'm "keeping it simple"
I've had the phone a week basically, and let the phone die COMPLETELY on Thursday morningish, and I charged it up and used it that day and let it charge to 100% that night. I unplugged the phone around 1:30am, this was Thursday night.It was never this good though, I'm really surprised to be honest! Ok, here's the pics. You'll note a whopping 11 hours of Awake time too. Below is from early this morning when I woke up - 1 day 4 hours unplugged: This is from just a moment ago (10am Saturday) - 1 day 8 hours unplugged: Oh and this morning I did some texts, took a couple of short calls, and 2 videos of my daughter's swim meet races.. Oh I also checked all of my work emails, and I had to send these pics to other email so I could get them onto my computer because I didn't want to plug the phone in yet. I'm going to see how long it makes it before it dies.. Shooting for ~50 hours Again, this was from a full charge and includes 1 day, 2 nights, and now another morning thus far. I plan to do but have not yet done the CDMA-GSM trick, the battery green charge on/off trick, and also monitor my TWS at some point - that will be for the next test though, as I don't want to muck with this test (normal every day use test)Edit: I see now if I disabled BlueTooth I'd save the battery even more, as it looks like it's sucking up a lot of battery and for no reason right now since nothing is paired or has been for the past ~24 hours.

Screen resolution was incredible (no pun intended), but the phone would get really washed out fast if viewed at an angle. My Hero's display is sharp at any angle, the Evo's screen must not have an IPS display, straight on is the only way to see well.
I did the multitouch test on the screen (the one that the Nexus One and other HTC devices didn't do so well on). It worked very well and didn't lose track of my fingers like the N1/Hero would.
4G in the city I'm in, except, driving around, it was almost not worth it. It's hilly and the signal would go in and out like mad, eating up battery and making applications stop while the phone figured itself out. At a stand-still the phone did fine, driving around, leave it on 3G, I would say. I literally felt like I had an original iPhone 3G on AT&T all of the sudden. I was just staring at the bars waiting for the signal to drop and my phone sit there like I had no signal. And btw, Clear's site shows my house to have FULL 4G, and I do not have a usable signal in my house and barely outside... Not enough of a gain in bandwidth to warrant even trying 4G at home. I'll just stick to 3G. They've REALLY got to work on that network. 6mbps? I am one of the only Evo's out there and I only got around 2.5mbps with a full 4G signal (yes, I know, Clear is used for other things than phones). That's 3G speed, not 4G. Can't wait to see how much switching between 3G and 4G eats up battery life...
Speedtest.net gave up to 2.5mbps download, and around 1mbps upload (capped). This is so-so fast, not really what I would call "4G" as my friend's Verizon Droid consistently gets 2mbps download, and he has a signal everywhere, unlike 2500mhz Sprint/Clear 4G. Also, 4G seemed to just turn off every now and then. I'd have to hit the 4G Widget off/on to get it to reconnect. Didn't happen but once, but still...
The User Interface is very nice, and that large screen makes browsing easy. The keyboard is FABULOUS. Used stock and Smart Keyboard Pro and I could type like the freaking wind. Love it.
The phone doesn't feel slim like the N1 or Incredible. It's a big manly phone. I wouldn't say the proportions are bad. It's all black and thinner than my Hero (pictures to come), but I certainly don't think 'oh my god how thin' when I look at it, like I do with the N1 or Incredible. It is very handsome. All black, very nice front area and very simple, nice back. Innards are red as all get out, of course.
2.1 Update 1 is running on the phone. No 2.2 here.
The camera seems really decent, from my minor use. Flash is BRIGHT for LED, and the sensitivity is impressive with low-light video.
Reception (3G) seems stellar. You won't have any issues here compared to other phones. It has great 3G reception. As for 4G, as mentioned above, we'll see....

I've been using my Desire for three days now, and been quite happy with it. Except for the fact that I can barely get three hours of battery life out of it, with "normal" use. (A couple of text messages/MSN conversations, quick web browsing every now and then). I've tried everything, turning syncs to 6 hours intervals, switching off 3G and WiFi, reducing screen brightness etc.
But the battery still loses about 1% per 1 minute. This can't be normal, right? Is this something that will improve over time? Could I have a faulty battery that needs replacing? I don't have unrealistic expectations for the battery life, just lasting for a full working day is enough for me, and I assume that should be possible.

There was another thread about this posted already but it had no poll!! Here's another with an actual poll. I hope this helps all of us get an idea of what kind of battery life to expect with the STOCK 1300mah battery.

I've tried BB 0.4 with two different kernels no good and kangerade 5.0.9 think. Still no good. Display is always on lowest setting possible but battery usage for display is well over 50. Only lasting 8-12 hours. First 10% drains in 10 minutes. Wtf!!! Overclock widget hasn't helped. And haven't tried setcpu. No credit card. So does setcpu improve battery life dramatically? Never had a problem with battery life before rooted Froyo. Ne suggestions? I just saw a new SS rom and new Chevy kernel. Anyone have any luck with them yet?

Is this happening to anyone else? sucks man...This is my second handset was flawless until this most recent update. After my phone comes off from a full charge it will die after 4 hours, no exaggeration! I have already tried closing the unwanted "syncing apps" still no good. What the heck should I do?

So I recently went back to my hero from my tour and the battery is just horrible. I'm getting on average 5-6 hours max as oppossed to the 8-10 I would before. Where do I start looking for leaks or figuring out what's going on.

I have terrible battery life with the 2.0d ROM. I don't really know why either as when I look at the battery usage, everything is pretty low except for the Cell Standby. On that note, has anyone else experienced terrible signal? Cause, I am.

I'm going to do a wipe and if it doesn't get better, i'll be returning it. My only widgets are sense weather which updates hourly, sportstap which updates hourly, Pandora, HTC calendar, and astrid. Am I missing something here?

Is anyone else having serious problems with the battery life? After fully charging the phone, I can't get more than 12 hours usage out of it, even if it's on standby for 95% of the time. I'm guessing something is seriously using up the battery somewhere but I'm not sure what. I've been to Settings --> About --> Phone Usage and it says where the battery has been used, but 40%+ is on Phone idle, and 40%+ is on cell idle (I'm guessing signal), but surely this shouldn't be happening, the figures on the Sony website give standby hours in the hundreds not less than 10.

I have HTC desire and find my battery life from fully charged to dead is between 4 hours to 6 hours.
Is anybody else having this problem or do you think the battery is faulty ?
I've only had the phone 4 months and find it annoying that i have to turn phone off to save battery. What's point having it as a phone if you have to turn it off..

I usually get bout 6 to 8 hours of usage before I'm in the red. Today I started a job and I haven't worked since I got my evo in june. From there till last night I havent put this thing down. Long story short, I'm a auto technician and my hands are always dirty so i haven't touched my phone but 2 times today. Been off the charger for 8 hours and I'm at 85 percent. At this rate I'm looking at 40 plus hours!! So there u have it, the secret to long battery life.

I've found that the battery drains so fast, so with doing some research I ended up going to settings > battery, and found that although my bluetooth is turned off, it's still the first on the list of battery consumption at 37%... I'm assuming that the battery is draining so fast because of the blue tooth, but at the same time I've checked and it is turned off. What am I missing here?? (Battery went from 100% to 13% in about 6 hours and all I did was send and receive a couple of texts!!!)

I bought a HTC Desire on a week ago and love it. Only problem is tat the battery is dire. I found it lasts for about 4 hours then it's dead. I am not running any apps or Wi-Fi, GPS, syncing etc. I initialy put id down to me playing with the phone constantly for the 1st couple of days. However by the fith day the battery was still dying in 5 hours or sooner. I took the phone back suspecting a faulty handset or battery. Got a new phone and battery. Still have the same very poor 4 or 5 hour battery life. I have loaded 'Battery Graph' app and you can see there is almost a straight line going down losing 20% of power every hour!!!! This is even overnight when it's doing absolutely nothing. I have also loaded Advanced Task Killer and go tthat shutting down any errant apps every 30mins. Still no improvement in battery life. Any ideas what may be causing this? Neither of the batteries I have had have hologram stickers on them like my old Nokia did. Should the official batteries have hologram stickers?

62 hours and 24% battery still remaining. This is after my initial period of hammering on the phone and back to my normal daily usage pattern which is like a blackberry user (some phone calls in and out, lots of email, at least a few every 30 minutes during the day and early evening). What this means for me as a blackberry user is that I can now confidently switch over from blackberry to the Evo as primary phone and get through a normal day (16 hours) without needing a mid-day charge.
Here are settings from my testing experience that I wish I had known when I first got the EVO at Google I/O:
1. Add to home sense screen:
widget: Power Control Android
widget: settings, 4G
widget: settings: Hotspot
2. Install android market apps (free):
Advanced Task Killer
Spare Parts
K-9 Mail
3. Run Advanced Task Killer (some disagree, do what you want. I'll revisit and retest this when 2.2 gets released by HTC for the EVO. I don't need sprint navigation, sprint tv, etc. to ever be running since I will use google navigation. I haven't had time to do another endurance test without using ATK and I'm not planning to do another endurance test)
Deselect things you actually want to keep running in the background, e.g.:
voice dialer
voice search
google voice
calendar
k-9 mail
gmail
....
Kill selected apps
ATK will put a notification up at each boot and remember your selections so it's easy to re-kill off all the sprint and other apps you don't normally want 'running' in the background.
4. Turn off 4G and hotspot on the main page with widgets installed.
Note: I found I don't need to disable gps or bluetooth since with streamlined apps running nothing is using them unless I want it to and I want my bluetooth to automatically pickup when I get in the car.
5. Turn screen brightness to low or medium using widget icon. this disables auto brightness but the lower screen brightness seems fine for me. When outside in the sun just click it up if needed
6. Settings Wireless and Networks, Wi-Fi Settings, <menu button> Advanced, Wi-Fi sleep policy, Never.
It's a bit counterintuitive, but I've tested it out both ways and confirmed the articles that recommend this. The phone uses dramatically less power in this state as opposed to auto sleeping wi-fi which turns on the 3G radio. Dramatic as in without keeping wi-fi alive overnight my battery went from like 70% to almost nothing during earlier tests.
7. <optional> Run the battery from a full charge to completely drained once. I'm not sure if this had an effect or not, just putting it in because I did it once before this current long runtime since charge to make sure the battery was properly profiled. It's easy to do with 4G on and watching HD youtube videos.
8. K-9 versus gmail client. I'm seeing much more cpu usage from gmail client versus K-9. I have work email on a host service that supports imap idle (rackspace). The imap idle push seems to really save on cpu usage and my work email delivers as fast to the Evo as it does to my blackberry. I like the gmail client for my personal mail but may end up switching my gmail.com to deliver via K-9 instead to really save on battery. Needs more exploring but it appears the gmail client 'push' is not as efficient as the imap idle.
9. Summary, when you want to show off your 4G Youtube HD or use the phone as a mobile hotspot, just click on the 4G and away it goes. But normally keep that radio off since you don't actually need it and it's a huge power drain. With the widget installed this becomes an easy habit.

Following my last thread for same reason,"full charge battery goes empty in less then 3-4 hours,even with wi-fi,gps, turned off",with tip of you guys,i monitored battery usage with "spare parts" app,first i haven't notice anything unusual: SPARE PARTS gave me very normal cpu usage:1-android system2-browser, but then in the end of list of usage option,i checked other usage & what i found was very interesting:
SPARE PARTS>battery history>other usage>total in all time:
running =time without sleeping 28.1 %
SPARE PARTS>battery history>other usage>since last unplugged:
running =time spend without sleeping 99.999 %
SPARE PARTS>battery history>other usage>total since boot:
running=time spend without sleeping 99.999 %
Now i guess i know why my phone run out of charge in less then 3-4 hours,question is what i have to do about it?
any solution please? previous post:with a full charge battery in STAND-BY, it takes just about 3-4 hours for battery to be empty! help!
also i checked main setting now: setting>about phone>status>Awake time 100%

I just bought a second hand Samsung Galaxy Portal, and it's a great phone and works fine, but the battery is dead 12 hours after a full charge. I had a task killer installed at first but I removed it after reading about how it drains the battery, so I'm wondering what else it could be? I know it might just be an old battery that's lost it's will to hold charge, but what can I check on the phone before I have to splash out on a battery or take the phone back? I know it has some decent tools for monitoring battery usage so what should I be looking for?

Since day 1 my battery has never lasted no more than 4hours so I decided to download Advance Task Killer (Safe mode) and changed the setting on what apps i wanted to sync (email,news etc.) at what time! Now, I can get atleast eight hours intill my battery needs charge again! Just a FYI guys.

At the end of every day, I'm running home to plug my HTC Desire to charge before it goes flat. Whenever I'm going to spend the night somewhere I always need to take my charger even if the phone is fully charged. This is exasperating, and I find it hard to consider relying on the phone when it's like this. I've had the phone for a few weeks now, so if things were going to settle down, I'd have expected it already. Pretty much all I use the phone for is SMS and Google Talk. Is Talk known to be a big battery drainer? Since I like the idea of it being a smartphone, I do have Weather, Facebook, Flickr, set on a 2-3 hour refresh. I have News set to Manual. GPS is off. Since I'm at a computer all day, I use that for surfing the web, not the phone. I'd like to use more apps on the phone, but I don't dare waste the battery since when it goes flat no one can contact me. I don't use an AppKiller. Actually I have "Advanced App Killer" but it seems kinda pointless when it just lists every app installed even if I never use them.

After dealing with short battery life like many of you, sometimes only getting 4 hours after a full nights charging and the phone just sitting on my desk,i figured out how to make it go the full day, even with regular use of web and email/sms. For me, it was simply reducing the frequency of syncs between all the various social networks I'm part of. My setting used to be every hour for Facebook, Twitter, and the worst culprit, Flickr. i would notice the phone constantly getting warm to the touch even if it just laid on the desk. Since changing the frequency to manual refresh, my battery is still well over 60% by nights end. YMMV.

My phone reads: 5h 32m 55 s since unplugged. And its at 5% now. Isn't this abnormally low? I used it somewhat frequently but not all the time or heavily by anymeans. Also, GPS and wifi and bluetooth were all off using the android power control widget. My battery usage shows: 42% android system, 25% camera (i took like 10 pics, nothing crazy), 13% cell standby, 12% display, 6% phone idle, 2% robo defense. This is after charging overnight to 100% And I've had the phone since thursday, so its like the 4th charge cycle. Is my battery defective? I read the other threads about low battery life but this seems BEYOND low, this seems defective.

For 2 days my battery has been draining quickly. This morning it is dead in less than 4 hours. I sent four texts. Checking battery usage, this is what I found: com.android.launcher - 46%, Beautiful Widget (just uninstalled) - 37%. I have never noticed these processes taking up so much battery. Background: I have been receiving a low storage notice so I deleted some apps, texts and pictures and plugged in for the night. The next morning the severe battery drain began. I was concerned about shorter battery life after the latest update so I have recently changed my settings to lower frequency for refreshing email, etc.
