I have this phone and the Nexus one. I can't tell you for sure what real world use gets you, but here's what I found today.
I had a class to go to. I took my MT3GS with me to the class. I have the HTC Flip Clock, as well as twitter, my texts, GPS on and minimal use during the breaks, and Silent Time Pro keeping it silent. I got home and my phone was at 96%.
My Nexus was left at the house. It has Beautiful Widgets updating the weather every hour. It has no facebook, no twitter, nothing that will sync other than my email. GPS and WiFi were off, as was the display. The only thing running on the phone besides beautiful widgets was Silent Time Pro. When I got home, I checked my N1, and it had fallen to 69% with absolutely no usage while I was gone.
Like I said, I dunno what real world use would get you on the MT3GS, but it seems far superior to the N1 at this point. All things considered, I think the N1 even with the faster processor should have fared better, as it wasn't used and basically nothing was on, as opposed to the MT3GS having GPS, a few things syncing, a few texts, and more programs running in the background.
This (to me) either means that A) The MT3GS manages power better OR B) Beautiful Widgets takes up far to much processor and battery power. Maybe I'll test it on my MT3GS later this week when I have some time off and see.
Anyway, there's my opinion. Take it for what you will.
I'm running the HTC flip clock, a few toggle widgets, the FeedR widget, Taskiller widget, and a calendar widget, and from fully charged to the end of my work day (few songs, few youtube vids, some texting, browsing facebook, etc etc) by battery is at about 25 percent.
I hate to say it, but my old Motorola Cliq would play Pandora through my entire work shift and still leave me with as much or more battery life than the slide does.
Honestly, not impressed with battery life so far.
My battery life has been ok, not great, some facebook, some twitter, a few hundred texts. some interwebbing. I can get around 10-12 hours from a charge it seems. which in my opinion is crap lol. i had a rooted cliq before this that was running only the basics in the background(killed all the bloatware and extra crap), i could get almost 2 days outta that thing.
I thinks once we get root and kill all the bloat and stuff running in the background, battery life will go through the roof. A vanilla 2.1 or 2.2 will prolly do wonders for battery life.
just my 2 cents

I almost feel like raising my hand and calling bs on 2 days with the cliq'r but i dont know you.
the cliq i used would get about 10 hours with use and 19 or so without use.
my g1 would get about 9 - 18
the mytouch 10 - 18
the old garbage samsung flip and sony flip phones 2 - 3 days.
this slide im averaging 10 - 12 with heavy use and 17 - 19 without much use.
keep in mind only had it for 2 - 3 days since release date but i did drain the battery and recharge it a few times the first day to break it in.
so far id say its about average on battery life.
i charge overnight
then either while driving, or working
then i connect to pc at home
with a full battery in the morning
and a slight top off mid day i never run out of battery life.
Hehe with my cliq I only had only the essentials running(there's a few custom roms out). So it went for almost 2 days. You can get the roms off modmymoto forums if you wanna check em out. The key to the cliq is killing motoblur =). Pm me if you want info shadow
I'm happy with battery life. First day I played with a lot, browsed a bunch and installed many apps and got around 12 hours(most I'd ever get from G1). Today I'm going on almost 24, took it off the charger at 4am after letting it fully charge, didnt start using it till around 10am and at 10am the battery still read 100% which I thought was wrong. Right now its at 17% (still havent gotten the 15% warning) at 1:30am, I'm sure it'll make it till 4. Sent around 50 text today, installed around two apps, and didnt do much voice talking or browsing but I did at least a good 30 mins worth from both. I periodically kill all with advanced task manager (except sense).

Amen. I carry a 3 in. USB to Micro USB cord that charges me at home, in my car and at work.
Those that are disapponted by the battery life are being unrealistic with their expectations. Power is too easy to come by to waste time *****ing about it. Makes you look too lazy or good to plug it in.

I purchased mine yesterday,and it sat on the charger overnight, and read a full charge in the morning.
6 hours 42 minutes later, it gave me a "battery life is at 26%" warning. WiFi, bluetooth and GPS were all off (all day)
I have it setup to check my email and facebook, but I had my Kaiser doing that and more for 2 days at a time with a smaller battery...
Usage-
55% Display (was set to auto)
32% Voice calls (20m 21s)
9% cell standby (6h 44m 59s)
4% Phone Idle (5h 10m 4s)
This seems absurd! If tomorrow doesn't do better, I'm taking it back.

.Realistic ... I never expect an electrical device that CONSTINTLY draws power to have a great battery, I dont race my car all day or let it idle in my driveway and wonder why theres no gas in the tank. a battery holds a resorce that regardless if yo like it or not .. will deplete over time. Advanced task killer is a great tool to get rid of th7e programs rnning in th7e back grond. to save batt life.
.Sorry for any mispellings, my laptops keyboard is taking a crap on me after it got rained on last night.

I don't think my expectations were high. Most people outside our community think "only a day" is bad battery life. I expected to be able to make it through 1 day without going dead. Being 3/4 drained after only ~20 minutes of talk time is absurd, especially since I didn't use the web or IM, etc. Just POP3 email every 30 minutes, and I uploaded 4 or 5 photos to facebook.
No Wifi, bluetooth, or GPS...
I just wanted to come back and reply now that I've had a couple days to play with the phone. I've been using it for about 16 hours straight now, quite a few texts, 5-6 short phone calls, and maybe 20 minutes of 3G usage, I'm at 66%. I haven't had this phone on the charger at all.
On the other hand, my Nexus, which has been on the charger all except maybe 2 hours in that same amount of time is already at 88%.
I think we have a clear winner in the battery life category. At least from my tests.
I am certain now that I have a defective phone.
I killed all running tasks, manually logged out of all IM clinents, etc, and then took it off the charger. I've made 12 minutes of calls today, it's only been unplugged for 4 1/2 hours and it's at ~%60 battery life.
12 minutes? Thats got to be a defect.
But, they are apparently out of stock... I might end up with a Touch Pro 2 or a HD2 after all...
Definitely not right .. I'm at 85 percent since 9am (7pm now), light use again though but its stand-by time is impeccable.. try and get another one, I can tell you the HD2 battery life is much, much worse, my father got it at the same time I got the slide and he's charging 2x a day. Mind you this guy would go the entire day with bluetooth,wifi, and gps on his G1. Oh and the usability of windows, well its just blah.. not trying to be biased at all. I have my brightness at 30 percent, syncng gmail only, and for widgets I have the curvefish battery widget, pure calander widget, power widget, and audiomanger. No bluetooth, gps or wifi on.
Have you tried going into the about phone in settings, and seeing whats draining the battery (click battery use)? See what cell standby is. Are you using 3g? May I suggest downloading anycut > new shortcut, activity, phone info. From there, open the short cut and you can adjust if you want 3g only (wcdma) or edge (gsm) only. Try setting it at one of the only settings, your phone might be dropping and picking up signal.
First post here, Hello World!
I have had mind for almost a week now. At first I was averaging about 1/2 day on a full charge. This was with Gmail syncing, no WIFI/GPS/BT on. Mild surfing, about a dozen SMS and 15 minutes of talk time.
I installed Advanced Task Killer and set it to shut off my apps on screen close. I am now able to go 17 hours ( a full day for me ) and I still have 15% left. This was with BT on for about 30 minutes of talk time, WIFI on for about 1 hour at the office, GPS on for clock/weather updates every 3 hours.
Overall, I am happy with the battery life on this device now. I am wondering if it took a while for the battery to calibrate and ATK helping with running apps.
I love this phone!

Sounds about like me. I don't use my phone to call much (go figure) but I listened to 15 min. of music, logged onto facebook for 10 minutes (3g) and sent probably 15 texts, and I was at about 65% in the 5 hours I had it unplugged.

Here's a question, Did you all plug it in and let it charge to full when you got it BEFORE using it?
Sure did. Ive made that mistake before, but I do that with all phones now, even though with a lithium battery, it shouldn't make that much difference.

Yea, I guess im just superstitious but I always do that with a new device. Have you tried recalibrating the battery? Charge to full, leave plugged in for like an hour after it says it's fully charged, wipe battery status, reboot, use normally? (if you can wipe battery status int he menu's without root) I'm picking my MYT3G slide up this weekend so I don't know if it can be done or not yet.
i think the battery life is great, i take the phone off of the charger around 9am. while im at work from 11aM-7pM i check my updates every hr or so. from 2-330 i listen to music also on my way home(7-8) and when i finally get back home round 8ish my battery is at about 58% then around midnight i get the 30% message. around 130-2am its at about 12% so i get 17hrs with medium usage
My battery life isn't too bad. 17+ hours since unplugged of moderate use (but only like 1% left): Display 41% (on Auto), Wi-Fi 25% (worked at home, kept on wifi for data instead of 3G), Voice Calls 22% (35 minutes; 14 calls), Standby 8% and Idle 4%. I think if you're more active in process management, it will help with life. I also just switched Brightness from Auto to a manual setting of about 20%. I un-synced Tweet and Weather and am running very few widgets, but keep GPS on. My K9 Mail syncs on an hourly basis and Gmail with Calendar and Contacts auto-syncs. Overall, MUCH better than G1.
Hey new myTouch 4G owners. I know your loving your phone so far but I and many others want to know one thing. How is your battery life so far? Compared to your previous phone?? and have it manage a day through your heavy usage yet?
Thanks!
P.S: if you can, report your "display" on time or just take a picture of "battery use" ..
I use the "Battery Left Widget". It's about 80% calibrated right now, reporting that my full battery life (based on my usage) is roughly 15 1/2 hours.
Having used the same widget on the Nexus One, I'd say it's pretty much right in line with what I was getting there.
Hmm I guess no great battery life then?
I must say though that my phone probably isn't the best representative for battery life... Reception here at work is weak, causing the phone to boost it's power output.
When I am at home, I get much better battery life.
I picked my phone up on the morning of launch and I'm still on my first charge (15% left). I've used it for calls, texts, pictures, videos, apps & widgets and I installed the ota update. I've had great battery life so far.

Mine only came about 60% charged.
So far my battery has been the best of any android phone so far (Nexus -> G2 -> MyTouch 4G). I have about 10 sync accounts going (2 gmail, facebook, rss feeds, etc) and with moderate use I have 40% or so at the end of a day. Screen is on auto, quite usable in any light.
Wow..not bad..so what are your display on time saying? It's in the battery use section, click on display.
guess not then
my battery is ****. I had to charge it half way through the day, but I'm an android noobie and lookin to get this thing going easily a whole day hopefully.
my battery life is ok. doesnt last the whole day for me but i text a lot make some phone calls and download apps and play games like assassins creed and nova.
The battery will need a few charging cycles to reach its full potential. I'd recommend fully discharging and fully charging it the first few times (and every so often after a few weeks of use). You probably won't get the most representative results on day 2 after launch. Was the same for my Nexus and G2

Oh ok i will have to try that out. I usually charge my phone when it gets down to 20 percent. But i left it fully charge over night
Mine seems about 4 hours shy of my G2.
My weekdays are 20hrs on G2 and about 16 on mT
Weekends are about 12 hrs on G2 and about 8 on mT
Amazing in terms of any other android phone I've owned.. Without a task killer
Sent from my HTC Glacier using XDA App
For some reason when it's rooted it lasts longer. If I don't root it the battery goes fast.
myTouch4G (Glacier)
i fully discharged when i got the phone and charged it over night. I went to an air show today and unplugged it around 9. its now 10 and i still have 25% left
(i uploaded pics to my blog and facebook, made calls, got text, checked football scores, and used google maps)
i'm impressed. Way better then when i had my EVO
everyone is giving answers as either "my battery life is great" or "my battery life sucks" but that doesnt really say anything... your battery life is gonna be amazing if you dim the screen to zero and dont use data :/ its all gonna be on how you use the phone and everyones gonna use the phone differently...
bottom line... the answer to this question just has to many variables
I am happy with battery life so far... while not analytical, I am getting as good or better tham MTG3. I was able to play Monopoly for an hour and the better was still 3/4.
I bought the MT this past Wed and when I bought it, the level was at about 40-50%. I was messing around with it, adjusting it and it lasted for a good 3-4 hours with the factory charge.
I let it die then fully charge and removed it from the charger. That charge held from 5am all the way until 1am the that late evening with regular use. It died and again I did a charge and disconnect.
I have done this same cycle for the last 3 days and right now. I can consistently keep a high charge for the most part of the day with average use. I disconnected the charger this morning at about 1 am, and here I sit now at 945pm with still over 75% charge.
Seems like this phone really likes the power cycles right now. Full to dead, recharge then remove until dead...etc.
Since Wed afternoon, I have charged my phone only 3 times since purchase, and right now it is Sat night. This is with average use, brightness set about 25%, auto sync only for email, weather, tmobile and no task killer used
You must remember this phone is using a powerful 1Ghz snapdragon, with a small battery. By default android uses the governor called ondemand, in other words it automatically shoots up to max freq during use. But once the 4G is rooted, you can use SetCpu to make changes, tmo will probably make an update though to address the issue. I can't really see extended batteries being made to small without needing a new back. I'm considering the 4G, I currently use both phones in my sig, my slide can get 2 days max, my G1 around 10hrs. It all depends on how you use the phone.
tips:
-turn down brightness
-turn off gps/Bt/wifi
-switch to 2g/3g/H depending on signal
-dial *#*#4636#*#* to modify radio settings(2g/3g/etc)
-turn off background updates(twitt/fb/flickr/etc)
Hoping to get some good feedback from those who have used the epic for a couple months or more. Now that you're probably using the device normally, as in not attached to it all the time, how is battery life? I've heard initial reports that it's not so good... Also, for those of you who have updated unofficially to Froyo, does the upgrade help with battery life? Can anyone comment how Epic's battery compares to EVO's?
Thanks.
I usually get about 9 hours in my stock battery and 6-7 on my cheap eBay ones. Overall idea say meh, its about on par with most other android devices. I'm running the stock dk28 leak as well with no battery tweaks or mangers of any sort.
Sent from my SPH-D700 using XDA App
On most of the DK28 roms I'm pulling a solid 10 hours with moderate use. For reference, If I leave the phone on standby all day in my house it's lasted 23 hours, if I recall correctly. Honestly that's pretty damn good for a smartphone.
EDIT: I don't use any battery-manager or powersaver either. Brightness = Auto, bluetooth/wifi/4g/gps = 1 is on at any given point in time usually. Google auto-sync = on as well as touiteur (twitter) and facebook notifications every 15 min.
I have been impressed by my battery life actually. I can't speak for the EVO(although maybe soon since my friend might give me his as a backup). I can usually get between 4-5 hours of play time(surfing, texting, apps, music, wireless tethering, movies, etc) The rest of the time it is usually idol. I usually charge it over night, unplug it around 7am, then plug it back in around 11pm. At 11pm, I usually have between 10- 30% battery left.
I just switched to a froyo ROM(bonsai, which is excellent) and so far the battery seems to be about the same. By lunchtime 12:30 it is usually between 70-80% and right now I am at 72% but I also had some extensive time testing the tethering feature.
To be honest, I had a blackberry, and the battery life was a little better, but the features were not nearly as good. It amazes me the battery these things get with that amazing samoled screen.
disclaimer: I do not play games outside of sudoku and spades, so my CPU does not really get challenged, which probably accounts for some battery savings. Oh and I use regular wallpapers, cause I don't really like the live wallpapers.
Im on 2.2.1,and I have to say I see a 40% increase in battery life compared to 2.1,and thats about 11-12 hours,no battery saving apps either,well except setcpu,which does help,but its set at 100mhz - 1ghz conservative.And I use it more now then when I got it,I havnt got tired of it at all.I have noticed the first 10% goes the fastest,and I have calibrated twice since moving to the ROM im on,and its the same in all,so if you get an Epic dont let that scare you.

I've had an Epic since a couple weeks after it was released and I think the battery is probably working the way they meant it to, which means a solid day. I charge it overnight, unplug it when I go to work, plug it in when I go to bed, and I'm usually at around 40% by that time with moderate use. I don't generally have problems with battery drain.
The exception to this is when using GPS with the screen on. It's really difficult to use this phone as a direct PND replacement even though it's basically made for it (especially with Froyo, which fixes the GPS lock issues), because the screen and GPS together will drain the battery from 100% to 0% in about 40 minutes. My dedicated PND, by contrast, will give me 8 *hours* of continuous use on battery power.
Also, I have a 1000mah car charger and even with that connected, the battery still drains when using GPS and the screen (it just drains slower). I have to just turn the screen off when I know I won't be needing to make a turn for a while.
The one thing I wish about the Epic is that it had a regular old LCD screen. The AMOLED screen is the one battery killer - you really need to watch how long you have it on. In normal use it isn't much of an issue, but you just can't do much of all the cool things they advertise that you can do with this phone (like GPS or watching movies).
I do also keep my screen turned way down, which makes a difference, but it's still a killer.
Well, I reported over in another thread that with Froyo, and basically having my phone sit around and do nothing with no WiFi, GPS, Bluetooth, no "fixes" such as switching to airplane mode or killing the DRM service, and no "battery saver" programs, I was able to get 108 hours on a single charge with the stock battery (1500mAH). That was with the screen on time of about 50 minutes and talk time of about 40 minutes... (pictures here)
It all boils down to how you use your phone, but in a stock configuration, the power management seems to be better on 2.2 than 2.1 as shown by the large amount of "idle" time I was able to get on a single charge.

I don't disbelieve that - in my post above, when I'm talking about draining the battery with GPS and the screen on in 40 minutes, or when I'm talking about having 40% battery left at the end of a regular day, it's almost always with a screen on time of 30-40 minutes. So 50 minutes sounds about right to drain the battery completely, with nothing else on.
I'll bet if you had 0 minutes screen on time - just let the phone sit idle - you could have probably gotten 200 hours or more.

No I know, I was more just clarifying so it didn't seem like we contradicted each other. I think the important stat is really screen time and then any extra radios you have turned on. Just with the regular radio and nothing else, you could get ridiculous battery life on the Epic. It's the extra radios and screen that kill it.
My phone gets me through the day. About 20% down in 7 hours on standby, so thats decent. Heavy usage with full brightness on and live wallpaper starting in the morning, stopping at like 6 A.M...it'd probably die there, for me at least.
The battery is good; I'm running the dk28 rom but it really hasn't affected my battery life at all.
On phoenix kernel i was getting 20-36 hours moderate to light usage. With acs xtreme kernel I'm getting 12-20 hrs w/ moderate use.
That's about 3-4 hrs of screen on time, 45-60 min of talk time. Emails, text ing, twitter, xda, and some various forum reading. Angry birds if waiting in line somewhere..
Note: I leave background data turned off and manually sync/refresh mail/contacts/data. I have no need/desire to be alerted evrytime someone updates twit/fb. I also use juice defender.
Sent from my SPH-D700 using XDA App
I can barely look at my phone on full brightness - it hurts my eyes with beams of awesome.
I get between 13 and 16 hours depending on how much Angry Bird time I put in that day. If I'm doing normal browsing, facebooking, etc then I'll be closer to 16, but gaming drops my battery like a rock.
Thanks for the replies! I think I'm convinced a lot of it has to do with how you use the device. Pretty much how it went with the EVO when it first came out... lots of people complaining about battery and then it kind of faded once everyone settled down. All I need is to get from early morning to right before bed.
GPS with google nav is a killer on any Android with decent screen size and resolution I think. Anyway, I thought SAMOLED is supposed to save a little battery? Or is that only if the background is black? In any case, I usually dim my screen to 30%, keep GPS off, keep auto-updates down to a manageable size, and use some other tricks to save battery, so I should be good to go.
I tried to thank all of you with the new thanks button, but didn't realize there's a limit per day haha. I'll finish it up tomorrow.
As far as I am concerned the battery life on DK28 is amazing. I use overclock widget set at 1000/200 screen on and 400/200 screen off. I can pull more than 30 hours with multiple phone calls, texting, email, web and games for over an hour. Here's the screen shot I took today before putting the phone on the charger.
I've noticed a substantial improvement in battery life since upgrading to 2.2. However, I also began using the Epic Experience ROM shortly afterwards, which boosted it even further. That, plus Juice Defender nets me a perfectly acceptable battery life.
I used my phone heavily today and still got about 18 hours out of it before plugging it in before bed at a 35% charge. On top of that, my phone's never felt snappier.
whoa, is it normal for the epic to take 3.5 hours to charge? If so, any explanation? Past devices i've had tend to take an hour less... Running 2.1, does Froyo help?
Currently on Epic Experience with SuperPower installed. I unplugged the phone about 16 hours ago and it's sitting at 36% with light voice and moderate SMS/data use.
Battery life definitely improved after upgrading from 2.1, even with light use it would be dead in under 12 hours on stock 2.1/DI17.
How to get unbelievable battery life
I have some very VERY helpful hints of great battery life for the Epic 4g. (as i am on hour 26 to 28 and have 20% left with about 1 to 1.5 hours of screen on use.)
First off, use black, or almost black background. Our screens are superAMOLED. This means that if the screen is showing black... those particular black pixels... are simply not on. If you have the home screen black, and have no icons on it, then the status bar is all that is using power... maybe 6 or 8 percent.
Next, Lose the brightness. A few helpful hints on this. 1) uncheck the autobrightness in the display settings 2) turn the brightness down in the display settings 3) If you slide your finger from right to left across the status bar at the top, the screen will dim, if you slide your finger from left to right, it will brighten(this causes accidental brightness 4) cover this light sensor on the right side at the top (I believe) because the phone seems to have a problem always autobrighting even with the uncheck in the settings. This is done best with electrical tape, or perhaps finger nail polish. These things should ensure to always be at minimum brightness
Next, Install Frankenstein Froyo Rom(lightest rom=less cpu usage/blackest rom=less screen battery usage), And Genocide Kernel(undervolted)
Next, install task killer(keeps the rom at optimum efficiency meaning less cpu usage assuming you are killing the apps 3 or 4 times a day) install set cpu(This allows you to limit the cpu clock speed(400mhz is optimal usable and battery settings)
Things to remember, ALWAYS TURN THE SCREEN OFF.
If you pick it up every thirty seconds to see if you have a text, then just sit it down... whats happening now.. The screen is staying on for another 15 seconds probably. DUH!!! bye bye battery!!
TURN OFF THE SCREEN BEFORE YOU SIT THE PHONE DOWN!!!
Turn off gps when not in use.
Turn off wifi when not in use.
Turn off 4g when not in use
Dont use it as an mp3 player.
Dont talk on speaker phone.
Those last few were pretty obvious.. but some people need to be told.
I Hope this helps anyone looking to conserve battery. Follow these steps and i promise 24 hours plus ever time and often as much as 48 hours.
Enjoy
EDIT****
By the way, When you set yourself up with this rom, you are making your phone TWICE as fast... LITERALLY. Hard to believe that a ROM could be twice as fast.
With stock android2.1 this phone gets 800 to 900 in quadrant(benchmark tool/tell how fast your phone REALLY is) Stock android 2.2 quadrant score is a little better scoring as high as 1000.
With this setup, i have gotten as high as 1950 in quadrant. No joke. This is reflected as you cant even tell the phone is clocked down to 400mhz without heavy apps and REALLY paying attention.
I used to get about 8 hrs of use before having to charge. Battery would drain even when I wasn't using the phone. Since flashing to DI18 a few months ago battery life has been great. A good 15-17 hours of moderate/high use and minimal drain with the phone on standby.
I lower the brightness all the way, end the DRM process and do the TWS trick after a reboot. No fancy battery management app that disables all your phone for the sake of battery.
I expect 2 hrs of the screen being on before my battery gets down to 20-30%. Which I think is very reasonable for moderate to high usage.
I have read many other threads about improving battery life and such but I am still at a loss. My battery in my Epic is only lasting about 5 hours(9AM~1:30PM). I have a moderate signal the whole time and I am using the phone but I only have the screen on about 10% of the time according to Battery Stats(forget where I found this info, maybe spare parts?)
I have turned off Wifi, bluetooth, 4g, GPS only turns on when I open an app that needs it. I really have no idea what I am doing wrong since this seems to be completely terrible battery life. I have also killed the drm service and have found that it did not help my battery life much.
I am rooted and running Syndicate Rom 1.0.2(not froyo since I use a Mac and have not gotten my hands on a pc). I am using Xtreme Kernel clocked at a max of 1ghz.
Any other tips? Should I take the phone to Sprint and ask for a new battery? The phone at this point is only about 3 months old. If this seems to be normal for battery life then I am pretty sure I will be jumping ship and getting a new phone.

Only advise I have is to toggle airplane mode after every boot and switch from the extreme kernel to pheonix 1.43, it has the best battery life by far as will any of the phenix kernels but 1.43 is the best

I got 25 hours of a charge the other day. Had to grab a screen shot real quick before it **** down. Might frame it. On stock dk28 with moderate use, lots of pics...it was on christmas so it was prety well used, trying to escape conversations with in laws.

I'm having the same exact problem. Same ROM and everything. I'm getting absolutely terrible battery life, maybe 5hrs on a full charge. Its ridiculous especially seeing how the nexus s is basically the same phone and gets nearly 20 hrs with no problem. WTF!!!??
Would bet a dollar that your phone is not entering sleep mode properly. Download Spare parts, charge your phone up, unplug it and turn the screen off and wait for like 10-20 minutes and then turn it on and open spare parts and look under Battery History. You will see that it will say Running 100% or something high like that.
This is probably because of something you set up. Either facebook updating every 30 seconds or maybe push email. I dont know.
I pretty much always get at least 24 hours and I work in a basement where I barely get a signal. I leave wifi on all day. I talk for about 20-45 a day on average. I listen to music for a couple hours a day. I play games for a good half hour of my lunch break and sometimes for an hour or two at night. Sometimes I forget to turn my gps off for half the day while I'm in the basement.
I have killed a battery in 6 hours when I spent the entire time downloading and playing games. And I had a battery last 42 hours a couple weeks ago when I was helping a buddy work on a car. We used it to drive some crappy pc speakers for music for about 8 hours in those two days and I spent a couple hours over those two days looking for info to help us diagnose his car.
I have been on Mammon's DK28 for a few weeks and have mostly been on the latest FroYo roms since the leaks starting hitting the public. I ran the same rom and kernel as you guys for a couple weeks, and I don't remember the battery being that bad. IIRC, I was overclocked and still saw 18+ hours of battery life with normal usage.
What are we doing differently? That is the question. Do you have a bunch of widgets and a live wallpaper? I don't. I try to keep my widgets pretty minimal. I have TWC on one screen, a flashlight widget on my main screen, and Pandora and PowerAmp on a third. I generally use a pretty dark wallpaper, too. Something simple and easy on the eyes as well as the amoled. I also keep my wifi on and set it to never sleep wifi. Why? So it doesn't search for a 3g data connection. I have wireless networks I can connect to in the places where I spend most of my time, so I might as well use them. Sure it has to power up the wifi radio, but the wifi radio seems to use very little power when you're sitting somewhere with a good signal. Also, read "How to Train Your Dragon" in the dev section. I have three batteries and generally reset the battery stats on one of them every two weeks. If you only have one battery, every 3-4 weeks is suggested. I always charge my batteries in the charger and almost never plug my phone in (because I don't have to) and about half the time I bump charge the battery after it is finished. Be careful with bump charging as it can reduce the number of charge cycles your battery can take, but can net you 10-15% more capacity in the short term. I rarely discharge my batteries below 15% except for when I'm recalibrating them. If you discharge your battery to too low of a voltage it can reduce capacity. And if voltage is reduced too low, it won't charge at all, but may be fixable with a cadex machine.
Be sure to go find that thread on how to train your dragon. There are some links in there that will teach you a good bit about how lithium ion batteries work and what you can do with them. After that, you need to see what is running on your phone to use that much battery. Is some process or group of process eating your processor?
edit: Look Mom, I wrote a book!
I will try changing kernels and updating to froyo(maybe hijack my dad's netbook).
If this doesn't work then I am going to go to sprint and see if they will swap out my battery. I tried the thing with spare parts and it says time running is 18% since last unplug which seems a bit high but not too ridiculous.
I have read and followed the instructions in how to train your dragon. I am really starting to think it is a faulty battery. I will report back, thank you everyone for the advice.
ok, thank you all for the advice. I am able to get through a whole day now on a charge since changing to Phoenix. Maxes out at about 10 hours as long as I am not constantly on it.
Updating to froyo later today.
Not really going to be helpful for you, but just my observation:
DK28 has MURDERED my battery life. Lots of people have issues with DK28, but the GPS, accelerometer, etc but all that stuff works fine for me - the only problem is the mega hit battery life took.
Let's hope the official release isn't as bad.
DK28 probably murdered your battery life because you forgot to do one of the battery saving techniques that you were using on your previous DI18 rom. Pretty much everyone else is seeing battery improvements with DK28.
I don't think so. I never use GPS, 4G or Wifi and I've always had the brightness auto adjust on.
Most threads about battery are quite outdated, so I decided to start a new one.
And so recently my battery is starting to get less muscular.. My Xperia Play is 4 and a half months old, and one hour of consistent 3G usage can drop the battery down from 65% to 24%. I'm not very sure whether that is the norm, but if it is, that's bad battery life, in my opinion.
The Android 'Battery Use' page shows that most of my battery is drained from Cell Standby and System Idle (30%).
My wireless and GPS is always off. Am on 2.3.4 rooted.
Also, Gameboid consumes battery like a beast (even more than 3G), but I guess that's due to the high processing power required for emulation..
Is there any way I can improve the battery life?
Personally I found battery life to be terrible on 2.3.4 so I downgraded to R800i_4.0.A.2.368_World. I'm running 122M-1.5Ghz with scary and BFQ, on top of that I undervolted every frequency as much as I could using incredicontrol (Id give you the values but they vary by device). I always leave wifi, bluetooth, gps and data off when not using them, turned off automatic clock updates (there was a battery draining bug with this a while ago) and I run at 10% brightness with autobrightness off. With this set up I lose maybe 3-5% per night, so for around 6-8hrs in standby while I sleep. Ive got similar results on both cyanogen and stock. That being said I don't have a data plan so I do save a lot by not having data on, but a 40% drop in an hour isn't normal - Ive played an N64 emu which runs the processor full speed for that long and only experienced a 15-20% drop.
imho, the best battery life i've experienced is on 2.3.4.. when i'm on 2.3.3 i always lost 30-40% overnight (wifi, bluetooth, 3g, etc are turned off) stock rom, locked BL..
According to some folks, if you're charging your phone and let it stay plugged in for a while after it hits 100% that screws with the battery life.
On 2.3.4 rooted with all the facebook, timescape and other bloat removed my battery is pretty good. Wifi is on 247 and it reverts to hspda when out. Data syncs hourly, and i have contacts, hotmail and gmail syncing.
The other day i was sitting at 57% after 1 day 3 hours, and that included a half hour go on fpse, might have been more.
Battery life seems good to me. I get 1 day usage then charge over night. I do use my phone quite a lot for this (Tapatalk), Phandroid app, Engadget app, Joystiq app and browser. Wifi and GPS is always on.
At a guess I'm using the phone for about 1 hour a time, about 7 times a day... So like 7 hours web use, phone calls and texts, syncing is set to every hour with FiX on.
When I was on 2.3.3 I'd be lucky to get 10 hours out of the battery but 2.3.4 is awesome.
Edit. Obviously I play games too. Forgot to mention that.

Actually I get similar idle battery drain rates as you, but personally I'm not very concerned with battery drain as long as it's not so much. I'm more troubled with battery life on consistent usage, which I feel the Xperia Play (or at least mine) sucks at.
When I play Gameboid, I get the same fast battery drop too - 40-50% in one hour.

Woah, 30-40% is insane! Glad that it's fixed for you.

Yep, I read that from a lot of places too. I admit I used to do that (and have since stopped doing that), but sometimes I can't help it if I forgot to charge at night before I sleep (and have to charge overnight to ensure I have battery the next day).

I envy your battery life One thing, if you remove Facebook, will your Facebook contacts picture sync go away too?
And did you remove the bloat stuff by deleting them from /system/app?

Sigh, I could never get such good battery life..
All the more reason to undervolt, in standby undervolting doesn't have much of an effect on the phone since the processor is either in deep sleep or running at its lowest speed. Also using a governer like scary or smartass helps keep your device running at a lower frequency when possible. Like I said 2.3.4 was terrible for me, 10% drain overnight or more, but apparently YMMV with this. That being said 40-50% drain in an hour is crazy no matter what you're doing on the phone, like I said running N64oid for an hour drops me 15-20% keeping in mind this is at 1.5GHz with sound and the backlight constantly on. If all else fails you can always wipe everything and start fresh, carrying over the same settings while jumping around firmware can lead to some undesirable results. Anyway good luck and keep us posted
The facebook sync option doesn't appear on my anymore, although it used to. To clean it up all i did was :
Purchase Titanium Bakup
Freeze the things I wanted to remove and test rebooting, only freezing a few more each time
Backed up every app
Slowly uninstalled each one with a reboot every couple of apps
Enjoyed my faster phone with better battery life
I use the gmail sync and life.contacts for contact pics
I get amazing battery life on 2.3.4.
In stand-by I lose 1% every 3'rd hours. It's very good in use too. Yesterday I had my day with heaviest use so far and texted like crazy the whole day and a lot of phone calls. Some surfing, gaming and updating of apps between that. Basically the phone was frequently used the whole day with short periods of stand-by in between. At night when I went to bed the battery was at 40%.
Earlier this week I used it minimally for 2 days. The battery dropped 10% for each of those days. But that was very minimal use.
So in short. I have not experiences better battery life on any other Android phone. What takes the most power is emulating. It can suck up like 20% in an hour depending on which emulator I use.
I got my Play at the beginning of the week and with quite intensive use, without WiFi or 3g, I scraped an 8am to 6pmish day on the battery. Admittedly with a fair bit of gaming.
However, that was only waiting for my 2600mAh battery to arrive and now I'm using it, I would recommend it for the bulk. You don't notice it after half an hour or so and I have no issues with gaming on the go whereas I always thought it may die on the stock.
mine drops 4 - 5% /hour..... much faster than b4.... dn no w is goin on w/ ma PLAY.....
I found that since updating to 2.3.4 my battery drains quicker. Usually charge overnight and battery would be around 15% bedtime. (7am - 11pm approximately)
Now I'm finding that by 6pm I'm having to charge it and that's without gaming
brought to you by the XDA app on my badass Android toy
Three times in my first week and a half of ownership I awoke to find it completely dead despite fully charging it or nearly fully charging it before bed. I usually sleep with my phone next to my head so that I can ensure that the alarm will wake me up. That and the lack of a timer function really irk me about this phone. I really hate having to create and save an alarm when I know I only have 45 minutes or 2 hours to sleep (I work a grave shift and have inconsistent sleep schedules during the day). It adds insult to injury when something changes that lets me get another 5, 10, 20 minutes or so and I can't easily add it. On top of that, I have to go back and delete all the alarms I made throughout the day!

Thats crap. Infact you should leave your phone plugged in a good 30/45 mins after it says fully charged if you want a full charge

Isn't it also beneficial to Li-ion's health to keep them at max charge whenever possible?...

Not at true max but at what the battery controller considers max. True maximum will drastically decrease the total cycles just like true minimum only to gain longer cycles in the short-term. When you store a battery it's best to stop at 75-80% because it will lose stored energy slower and not spend nearly as much time near 100%, which is still a trade-off between long cycles and more cycles.
What do you guys think to this?

(Please add the WWW)
Its the same size as the standard stock battery so there's no extra bulk... But gives an extra 930mah?
To be honest, I am somewhat tempted... However the question is, will it explode in my pocket and result in me losing half my leg? It's quite a big risk to take! There also might be a voltage difference, however I cannot see anything on that.
Im currently on 1.6Ghz, undervolted. And I just played Order and Chaos for 35 minutes and went from 86% to 63% - I've had bad luck in the past regarding phone batteries, I remember replacing my G1 battery around 7 times, but at these rates my Play would be dead after around 3 hours or less of gaming.
how do you update to 2.3.4 it wont show me =[ please someone answer me :/

You have to expect that with any phone playing an online game. Wifi/screen/GPU/CPU are going at full wack at the same time. What dya expect?
