Battery life

Since I've installed the new software upgrade battery life has gone down. Can anyone recommend any settings/tips to maintain battery life?

not noticed any difference in battery life so far. are you playing with it a bit more because youve got the update? first day i upgraded mine i was using it a lot more and reinstalling all my applications and settings so the battery dropped faster. maybe give it a week or so until you settle back to your normal usage pattern.
main tip to increase battery life is to lower the screen brightness as far as you can. i think i have mine on about 10%. i can still see everything fine. the light is the main drain on the battery. also if you dont use 3G u can disable that. if youre in an area which has bad reception that can drain your battery faster because its constantly seeking and trying to get a lock. not much you can do about that apart from turning the phone off or putting it into airplane mode until you get to a better area.

I have the same troublem too,even Battery charge some time do some time don't

Nope, no problems. In fact today with mild usage of a few calls and sms's it has only gone down 9% in the whole day. I am satisfied with that.
BTW, there is already another thread for this issue. If a Mod can merge them, that would be cool http://forum.xda-developers.com/showthread.php?t=684651

wow i ussualy had to charge it every day, now with the update today os my 3rd day without charging but i have to charge it tonight

hmmm that would drop here in 3 mins of call
i figured out mine drops 3% per minute <---in call
and "energy saving mode" it lasts 15hrs

Hi
after GEN_EN 35, i'm having a better battery life than before.
my battery did great for just one day with simple usage, but after update i'm having about 2days life on. but with hard work and a busy day on call answering on BTooth and sms , little WLAN,.... i could finish the second day with light work today.
since yesterday morning, after about 31hours (about 13hrs work and remaining on standby) and did 2times restart, i'm having 30% battery remaining.

I guess I still long for my k790, that would last for 4-5 days for me, unless I was using the camera flash. I am getting battery drain similar to lock3k and indycar so I guess it's normal. I also browse the net most of the day and while driving between edge and 3g zones. I can get away with charging once a day so I guess it's ok.

yah. my battery is getting owrse and worse. I charged it last night before bed. woke up today it went down to 70% ... I obviously didn't even touch the phone, cuz I was sleeping ,,unless I'm a lunatic (which I hope I'm not)
so wth?

Come on man are you serious only 10% of brightness?? If this is true, I must agree that you will save a lot of battery life, however, you will kill the beauty of the screen! You have a WVGA resolution screen which is awesome!
So decreasing the brightness level this way will make you miss a great treat which is how wonderful the screen really is, anyway it's your call man but trust me your missing a lot
Personally, I set the brightness level to 70% and I have no problems with the battery at all! It works all day with heavy multi tasking along with taking pictures, many SMS and browsing the internet. Before I sleep everyday I charge it and that's it.
I think the battery on the X2 is very good. My only concern was that the software will stay unfixed for ever, specially after a lot of complains regarding the MR2. However, since I upgraded to MR2 this device is among the best I have experienced in my life, I'm loving it everyday more and more. And no matter how good other smart phones are, the X2's keyboard is simply unbeatable along with the other goodies it offers you.
In my opinion the best way to save the battery life along with enjoying your phone is :
Go to the setting>system>phone>band
And change it to GSM instead of auto, and if you want fast access to the INTERNET your better off with the wi-fi but don't forget to switch it off when ever your done.
Cheers

Good idea about switching to GSM only, but I have 3G on all the time and my battery performance is just fine. This includes having the SD card fix applied which disables power save mode on the SD card.
I don't understand how some people here are having terrible battery life.
Of course it is very important when you first get your phone to charge the battery fully and let it get to really low before charging again, then charge again for a few cycles the same way and it will be a very good performing battery after that. You can also refresh/maintain your batteries the same way. It may fix batteries that were not properly charged the first time, but they should be relatively new. As a warning though, don't let you batteries go completely flat. It's very bad for lithium ion batteries.

Thanks for the advice dude and what you said is totally true. However, since most users lack such knowledge and experience they will end up having a bad battery that's not using it's true capabilities.
So I think it's good for people to know how to charge there batteries probably from the beginning. Regarding the 3G and 2G networks, trust me man there are a lot of users that are only using the phone as a phone nothing more, so giving them the 2g option is the best for them.
But of course a person with a decent experience such as your self has no problems at all staying on a 3g network
Good day

Modern batteries don't require any loading cycles.
They are prepared already.

Yep, he's right! It should already be ready from the factory.
There is one thing to note, NEVER OVER CHARGE A LITHIUM ION BATTERY!
Unlike NiMH, they do not have trickle charge so leaving it charging for long periods of time or charging it over and over when it's close to full can actually damage the battery.

im getting these strange readings from battery meter
the temperature seems very weird as room temp is 28 (at work atm) im currently
charging the phone and it shows me max 4 degrees C but the battery is very hot

Galaxy Tab getting better battery life than official specs?

Yes, according to this guy.
http://forum.androidcentral.com/galaxy-tab/44768-bettery-life-results.html
Anyone feel the same way?

its better than i expected, but i doubt its better than sammys tests

Same here it seem way better than I expected but I haven't tested the battery life thoroughly yet but indeed it is very good.

Tomorrow I will be flying back home. I'll be in the air for about 6 hours. I have 2 movies to watch, plus I'll be playing games and will listen to music. I am planning not to charge my tab until I get home. Let's see how it goes. I will update.

Being that my battery use is ~80% display, i should probably consider turning down the brightness. Still, I have been playing with it here and there throught the day (about 7 hours away from the charger now) and the battery level is still 75%
Somebody needs to find a way to mod the autobrightness to have a few options...I like the feature, but it is just a bit too dim for me.

My tab lost 10% battery for one hour medium usage (display on, 30% brightness, reading mainly). Dose it mean I have a battery issue here?

no. it just depends on what your doing. Wifi signal strength, Cell radio strength. the position of the moon and sun, etc.
BTW, battery life does not decrease linearly. so the numbers in that post are ridiculous.
the discharge curve will look something similar to this in most cases

(red line, also note phones cut off the extreme ends of the scale with regards to voltage to promote cell life)
it takes a few days for the battery (more specifically the charging circuitry) to get into a 'groove' when it comes to properly charging the battery and displaying the correct percentage.
if you want to know more about the Batteries in our phones and Tablets look at RCcar and RC plane sites. they use the same batteries as phones do so pretty much everything you learn there will apply here (except our phones don't draw 20+amps! )

Mine can easily last and day and a half, very impressed with the battery

Well, I understand you saying here. But 10% (90% to 80%) per hour for reading ebook only is far away from having a good battery at 4000mah. I will give it a few more days to check.

That's 10 hours at that usage, give or take, and right around what I'm seeing, 10% per hour of actual usage as an ebook, about 2-5% per hour if it's just sitting there connected, and about 15-20%/hour with heavy surfing or game playing.
I expect if I'm careful and keep the connectivity to a bare minimum, I can stretch 12 hours out of it when travelling.
Oh, and everyone...let the battery run down to zero at least once, preferably twice. We're talking total discharge to the point the phone turns itself off, then charge to 100%. This doesn't hurt or help the battery, but it does help make the actual battery monitoring more accurate.

honestly im not too impressed with the battery. i think the standby time sucks too. the iPad doesnt do a lot of things right, but the one thing it seems to do is to last for days. i realize the battery is close to twice as big but i was just use to that. i mean sure i dont use my ipad anymore, but it seems to last forever. anway, when i first got my tab, i managed to drain it in less than 6 hours. that was right out of the box (so it proly wasnt full all the way, but close to it). i was mad when that happened. that was with the brightness on auto and everything turned off except wifi. i could be just expecting too much. i thought conditioning the battery would be good for it. so i let it die all the way and recharged it to full. today, i wouldnt say i used the tablet like i usually would (i am a HEAVY user) and its been less than 12 hours and its already at 21%. this time it was running on 3G and brightness on low (not all the way, but about 30% or so). i dont even set the brightness to the highest cuz its too bright, auto seems to work the best. maybe im just being a tough critic. i mean my nexus only lasts like 5 hours now a days cuz i just use it too much. but im so use to just picking up another battery and moving along.

been having a good battery life after draining the battery to 3% twice then charging it to full again and now it almost last me 2 days better than my old nexus one using it primarily for comic book reading and bluetooth stereo music almost 6hrs. per day and a little gaming of angry birds and a little video and youtube + browsing calling and texting really don't like games too much
@croak
i've read a forum sometime ago that it's bad to drain li-ion to 0% so i think its better to drain it to near zero before charging again as i've read it may damage the cells if you drain it to 0%

how often should we condition the battery? (let it drain near 0 and charge up)

Doesn't hurt a lithium ion battery much at all, it's just another charge cycle.
But if you don't go down to the point that the device shuts off at least once, your battery meter can and often will be off by a good bit. There's never any confirmation. When yours was reading 3%, it might have actually been 8%, or it may have been 1% or less, but until you zero it out, you'll never know, and neither will the device. It'll still know when it's at 100%, but any reading below that can be inaccurate.
And keep in mind, this is NOT zero charge, it is not completely drained (the device does the auto-shutdown specifically to AVOID a complete drain).

Lithium Ion batteries don't need to be conditioned. But if you want to calibrate the battery meter, you'll need to do it at least once.

Using my Tab as a 3rd device, with my 1st being a HTC Evo and my 2nd being a Motorola i890, i am very impressed with the battery. Even treating my 1st and 2nd devices as red-headed step children and my Tab being in my hands more then them, my battery is yet to go below 50% in a day, the week i have had it. Even with checking 7 different email accounts every 5 min. Also, my Tab is on Wifi a majority of the day, which i would think puts more of a drain on the battery.
i was a little worried when i found out that the battery was not accessable to be able to swap it out at some point of the day. I have (6) batteries for my Evo, 2 red and 4 blacks. Before my tab, if my evo didnt touch a charger during the day, i would use atleast 4 of those batteries during the day. Yea, the size difference between the Evo and Tab battery is different, so i figured i wouldnt need 5 more Tab batteries, but atleast 1 or 2 extra.
My only complaint with regards to Power/Charging is the length of the USB Charge/Data cable. It is super short. i bought a 6ft extention @ Staples for about $5!
The fresh Tab battery is only spoiling us and will get worse as time goes by. I have been looking for other options in the mean time. Here are a few options i found:
ZAGGsparq 4000 mAh $90 @ fommy
Mophie - Juice Pack Powerstation 3600 mAh $99 @ BestBuy
ClearMax External Battery Pack 5000 mAh $39 @ eBay (questionable)
eGear UB-181 1800 mAh $19 @ eBay
eGear S220 (3-way charge: Solar,ac&usb) 2200 mAh $39 @ eBay
Yoobao YB-602 Power Bank (White or Black) 4800mAh $49 @ eBay
Personally, i think i am going with the Yoobao or Mophie or ZAGG.
***EDIT***
the ZAGGsparq is 6000 mAh, NOT 4000 like i stated above...

Yoobao has only 800 mA of output, too few !
Sent from my GT-P1000 using XDA App

The ZAGG has 2 x 1000 mAh. i wonder what the output is @ 1? I doubt very much that it is 1 x 2000 mAh...

Im impress with the batterry , way much better than my Ipad that I just sold ...

My Nexus battery issues have FINALLY been solved

I've been one of those that have ALWAYS had terrible battery life with my Nexus. Even using SetCPU and Juicedefender, it would drain horribly, even while it was asleep. I've had three different stock HTC batteries and also used the Seido 1600 mAh, none of which made any difference.
I finally decided to try an extended battery, if for no other reason than to simply get a little more juice so maybe my battery would last longer than 6-9 hours. I figured I could always return it anyway. The only way I have ever gotten 12 hours out of a battery is to not use the device hardly at all. I went with the Mugen 3200 mAh extended battery because the Seido 3200 mAh has a battery door that does not seal the device so dust can get in. I might have tried Amzer but I didn't know they existed until after I bought the Mugen. All I know is that I am freaking THRILLED. Right now, I am sitting at 82% and I have been unplugged for 7 hours and 55 minutes!! I'm still only on my third cycle!!! Yesterday I was at 55% after 18 hours of use when I finally started a new charge cycle. I'm talking normal-to slightly heavy use...I even streamed two episodes of Seinfeld from TBS.com.
I'm posting this for those that are at their wit's end over battery life on their Nexus One. I swear I always thought the Nexus One was defective when it came to battery life. Now I know I have always had crappy batteries.
This is in no way an advertisement for Mugen..I have not been paid or given a discount, or been asked to post a glowing review...I'm just so happy about the Mugen working beyond my expectations. On top of this: I managed to break one of the pegs on the extended battery door they sent which makes it a little loose. I contacted them and before they even replied they started shipping me a new one at no charge!
Anyway, if you are having the same issues as I have been I would suggest a 3200 MAH extended battery. Either Mugen or you can try Amzer. I personally would not get the Seido based on their battery door not being sealed with the potential to let dust in, and the fact that my experience with their 1600 mAh battery was so bad. I'll personally always go with Mugen from here on out based on performance + customer service. If something goes wrong I already know they will take care of it one way or another.
Remember the drawbacks tho: slightly larger profile due to larger size battery and door, cases will not fit device any longer, and it will not fit in car dock any longer. In my case I have put a stock battery and original OEM battery cover in my car so if I want to use the car dock I can just switch batteries and back covers.
Anyway I hope this helps someone find peace with battery life. It's been driving me up the wall for almost a freaking year now. I never dreamed I could get this kind of battery life out of my Nexus One. So nice to be able to stop checking battery status all the time.

how much thicker is it?? can ya post a pic?

pics or it didnt happen.
or as they say on 4chan "tits or gtfo"

Okay here they are guys, I have two Nexus Ones so I used one of the to take the pics, unfortunately I cannot do a side by side of the two Nexus Ones because I need one to take the pics as I do not have any other camera:
first a comparison of the Mugen 3200 and the HTC stock:

And finally, the broken peg on the extended door which I broke and Mugen are replacing for free(it's the peg on the top):

sorry the pics are so big I don't usually do this but I suppose it might help that they are big. If you want more info or pics just ask. hope this helps. Tomorrow I will post a pic showing how long the device has been unplugged with the remaining battery percentage in the status bar at the same time to prove my claims. I cannot do it now since I pulled the Mugen to take the pics. I should have done that pic first, then pulled the Mugen.
I just want folks who are in my same position to know there IS a solution, albeit with drawbacks such as not being able to use a case. I have to admit tho: I don't miss any of my cases. The Nexus with this extended back feels great in my hand. The only real drawback for me is the risk of dropping it without the case to protect it. I'm just being more careful and FINALLY enjoying great battery life.
One more thing: this is all done with display brightness at 100% 24-7. I do not like using any other brightness setting so if you choose to use an energy saving brightness setting, your results should be even better. I do however still use setCPU to downclock to 245 while screen is off, and juicedefender with various settings.

...What?
Maybe I'm the only one this has ever happened to, but whenever I check my battery usage statistics in the default Settings app, Display is listed as the absolute biggest battery hog, by a ratio of at least 2:1 compared to the next highest component on the list. I'm talking like a consistent 60% or more of my battery drain is attributed to the display, and this is even when I have my display set to automatic brightness 24-7. Even if I overclock my CPU to 1152mhz, turn on Bluetooth and GPS, and play games until my battery is almost dead, the display still racks up the highest amount of battery drain.
I hate to dismiss your claims as unscientific, but did you ever think to check your battery usage statistics? Did you ever figure that maybe you could be killing your battery life by leaving the screen on max brightness?
If I leave my phone on automatic brightness, I get a good 15 hours of battery life with moderate usage throughout the day. If I put it on max brightness, I go down to about 6 hours of battery life. Weird, huh?

Uh, yeah, no kidding the display brightness kills battery...but I do not like turning down the brightness at all, it hides that beautiful display. Besides don't you think that over the course of a YEAR I tried turning down the brightness?? Sure it saved SOME battery, but not enough to matter...maybe two hours extra which is not even close to being enough for me to justify turning it down. I have two Nexus Ones and have tried the turning down the brightness trick on both and the battery savings is minimal. No-matter how much I turn down the brightness, the display is ALWAYS listed as the biggest battery hog(unless I use the phone for calls a BUNCH that day)
and I never claimed any of this was scientific. Try a 3200 mAh battery or don't, I don't care...I'm just posting my results. To me getting 18 hours out of a battery and not even being at 50% yet is a huge difference...far better than turning down the brightness.
But again these are my results and I cannot PROMISE anyone else will see the same thing. Can't hurt to try and just return it if it doesn't work out. God knows I tried everything else over the course of a year.
If you want to fault me, I guess I shouldn't have said "there IS" a solution since I cannot promise this result for everyone or anyone but myself.

well the battery is double the capacity of the stock one, why would you be surprised that you get so much battery life? I'd be surprised if it doesn't.

Because i'm getting FAR better than double battery life. If I had gone from 9-12>>>>>18-24, I wouldn't have even made this post. But I have gone from 9-12(oftentimes 6-9 with heavy Flash use)>>>>>>>over 40 hours with normal to heavy use, even streaming Flash episodes and movies.
This is not for the normal person with pretty good Nexus battery life: this post was/is for people like me who have been frustrated by people posting that they get all kinds of great battery life from their Nexus but are never able to get it themselves. I finally got it for myself.
hell I saw a video review by some kid of this Mugen battery and he said he thought it was great but was giving it away because he already gets great battery life on his Nexus ....that pissed me off right there. I was like what the hell???
here it is:http://www.youtube.com/watch?v=AzSm2fBOBFQ
so yeah I'm excited to finally have great battery life myself and thought I would pass it along as a possible solution for others

Uh, yeah, no kidding the display brightness kills battery...but I do not like turning down the brightness at all, it hides that beautiful display. Besides don't you think that over the course of a YEAR I tried turning down the brightness?? Sure it saved SOME battery, but not enough to matter...maybe two hours extra which is not even close to being enough for me to justify turning it down. I have two Nexus Ones and have tried the turning down the brightness trick on both and the battery savings is minimal. No-matter how much I turn down the brightness, the display is ALWAYS listed as the biggest battery hog(unless I use the phone for calls a BUNCH that day)
and I never claimed any of this was scientific. Try a 3200 mAh battery or don't, I don't care...I'm just posting my results. To me getting 18 hours out of a battery and not even being at 50% yet is a huge difference...far better than turning down the brightness.
But again these are my results and I cannot PROMISE anyone else will see the same thing. Can't hurt to try and just return it if it doesn't work out. God knows I tried everything else over the course of a year.
If you want to fault me, I guess I shouldn't have said "there IS" a solution since I cannot promise this result for everyone or anyone but myself.

Your original problem wasn't that your stock battery was bad, it was that you kept your screen brightness too high to be suitable for daily usage. Proposing that the only working solution for yourself was to buy an extended battery is very misleading, because really all you had to do was turn down the display brightness, and make sure to turn off unnecessary services like GPS, Bluetooth, etc.
Furthermore, your solution, which is to outfit the Nexus One with the Mugen extended battery, costs $80, while it costs absolutely nothing to simply press a button and save your battery by turning things off and dimming the screen.
It's fine if you want to buy an extended battery so you can blast your display, but it's not the only solution, and is possibly the worst in terms of cost-effectiveness. Anybody at their wit's end about their battery life should try everything else first, and only then when they are completely dissatisfied with the way the screen looks, the lack of available services, or the lack of speed in processing, should they consider purchasing an extra battery.

dude I already told you that turning brightness all the way down only netted me about two hours more battery life using stock battery. And thanks for quoting my post about being at "wit's end"...by definition if you are at your wit's end you have already tried everything else.
is this the best you can do or are you just argumentative tonight??
I fully stand by everything I have written
and for the record, turning off GPS, turning down brightness, turning off bluetooth, etc.., is not a REAL solution, unless you consider crippling your device to keep it powered a solution, which apparently you do.
Maybe I should just turn the whole device off.... then I'll get weeks and weeks of battery life.

Thanks for taking the time to post pics. I too use my display at 100% bright and love the effect. I have a spare battery i use and a charging dock ( not oem ) and i get by doing it that way and can make it abotu 12 hours before i have to reload the other battery ( stock battery )
I had a mugen on my g1 and it was an awesome addon. However, the otterbox defender im using now wont fit a modded case, so this was the best solution for me.
i think we all are great to find solutions. Even if different ones. One thing i did find with the "fat phone" was that it felt better in my large hands and was more comfortable to type on.
Make sure to post a follow up to this with final thoughts on the battery . and thanks again for tits

No problem man, and I agree with you about us each finding our own solution. After I get done cycling it two more times(per instructions) I will post final results. I have to admit I do fear it losing capacity...almost like I can't believe these results will be maintained. My worst fear is that in a couple weeks things will start going downhill again. If it does go downhill later I will report that, too.

Good to know. When I see these threads I wonder what I'm missing with my phone, cause I get 2-3 days with my battery. I must be missing out on something cool.

I can get that with mobile data turned off, but when it's contatly syncing 3 email accounts, facebook, twitter, news, weather etc over 3G, I kind of expect it to take a hit.

Except it's not.. All of these third party extended batteries are 75-80% of their stated capacity. Therefore his battery is at best 83% larger.
http://batteryboss.org/ says that Mugen 3200 are 75% of their rated capacity, therefore more like 71% more capacity than the stock battery.

Yes I've replaced my stock battery with two others: stock HTC batteries and a Seido 1600mAh extended battery, all with the same results(bad battery life). I just bought them tho and didn't bother with warranty replacement. Looking back I guess I should have. Anyway I DO think it's possible they are all defective due to my having repeatedly run them down to 0% at times. The Mugen came with a warning to never ever run the battery down to zero percent. I have also read here and at other sites that running them all the way down is bad for them. I'm no battery expert so I cannot say for sure, but you make a valid point.

My stock batteries would sometimes shut down the Nexus even tho it still showed 15% of power left: I would resolve this by wiping batter stats in recovery. Yes this is a concern I have but I cannot test it as I am not willing to drain this Mugen below 20%. Right now the battery has been off charge for 21 and a half hours and I am at 59% battery life left. When I am done cycling this battery I will hopefully never have to deal with seeing that battery get to even close to 15%, 20%, etc.. because I will be going to bed and putting it on charge long before then. Also, I do not want to risk draining this battery 100% as Mugen warns not to do that. They are very explicit about this.

I must also add that I do not use Facebook or Twitter(I use launcherPro Twitter widget but sync it manually) I removed the official apps via Titanium. Thought I should mention this since you reminded me with your post. This can also contribute to my good battery life, although it never did much good with the stock batteries, but again maybe they are defective.

i've read the same here at XDA and at other sites and it's a valid concern worth mentioning. For me it doesn't matter what they rate the battery at as I'm experiencing fantastic results, but that does not mean Mugen does not fudge numbers. So again a valid concern. My advice is to try it and return it if you do not get satisfactory results. If you get horrible battery life, my opinion is that it's worth a try.

hey Paul, yes I cycled the stock and Seido as recently as last week. I've tried every trick you find in a search here at XDA or Google. I even tried that trick where you drain the battery repeatedly to reset the battery meter, then charge it back. Also tried the trick of power to 100%, letting it drop to 99%, then turning off and placing back on charge. Light turns amber again and charges for another 30 minutes or so. All this did was make it stick at 100% for some extra time(usually an hour) then it would start dropping faster than normal tho.
Just for the record guys: I understand the skepticism. I was always skeptical of battery power claims. I suppose I wouldn't believe me either if I were just reading my posts and not experiencing this.
Again: I have been off power since 2pm yesterday and I am at this moment at 58% battery power left. I did sleep for six hours and didn't use the device for that period, but still, for me, this is incredible.
EDIT: one other thing I forgot to mention I do: I am ALWAYS checking and making sure my Nexus is sleeping properly via Spare Parts. I have had apps that cause my device to not sleep properly and that hurts battery life. In fact, just yesterday I caught the latest WeatherBug Elite update causing my Nexus not to sleep for the second time since they started recently updating it. I have now returned to a previous version I backed up and am having no sleeping issues at this time. If you are having poor battery life it is something to check and keep an eye on.

Battery life

Has anyone seen awesome battery life with this thing or is it just me!? It's been off the charger for 4h20m and the battery is as 87%. wifi off, gps off, bluetooth off, sync ON. just text messaging all day, maybe 20 texts total (slow day today). little bit of facebook, little bit of email, thats about it, so i didn't really do much with the battery but even so with this kind of use my evo would probably be down to around 70%.
battery indicator pro says the display is responsible for 64% of the power drain and cell standby is only 12%, whereas my evo usually had around 50% cell standby and display was only like 8%. was the evo just really bad at holding a signal or what? my display is at middle brightness, if you use the power control widget.
can anyone else tell me how much % their display uses? and what their battery life is like?
after typing this post it's only dropped 1%. word.

Personally, I don't have much of a basis for comparison. I just got my Shift on an upgrade from an aging Samsung feature phone. I've heard all about the horrid battery life on the Evo. My brother has one and can't get a full day of use.
I was out with a real estate agent looking at houses for 6 hours yesterday. We used the GPS a little bit. I was checking NFL playoff scores every hour or so. I was also texting/emailing lightly. 4G was off. By the evening when I put it back on the charger it was still in the green. I didn't look at the power meter specifics... wish I did.
And today I'm just about to leave the office right now. I'm at 8 hrs, 59 min since unplugged with 6/10 green battery bars. (Hey... how do I get the exact percentage? Thanks!)
Display is 62% of my usage (It's set to Auto-brightness). Android system is next at 20%... Light email/texting use all day long at work. Played games for 30 minutes during lunch. Downloaded some new apps (using 4G). Wi-Fi and GPS off all day.
Overall it's a little better than I expected. But I know I haven't really had a heavy day of use yet.

Battery Indicator Pro is a great app that runs in your menubar and displays the percentage for you.
glad we're on the same page with the display, though

I almostmreturned the phone. My cycles were:
1st 8+ hours
2nd 4 hours
3rd 2 hours
Did a factory reset on the phone and it has started to turn around.
4th 9:40 min and at 30% when on the charger
5th 10:46 and still going. Battery is at 30%

I've recharged twice since I got it on Saturday. This seems great, coming from the sprint hero

Exactly. My hero sucked. I used my phone lightly and had it without a charge for over 24 hours. Did some playing around setting it up and then some light texting, emailing, and 4g usage. Then turned off 4g. Amazing.

This isn't your dream phone, it's the one after that. You gotta take it out and play with it more!

I've had to charge it twice a day since the sixth, battery life has been terrible.
I have all the stuff disabled, it just seems to drain even when nothing is running.
I did have an issue with terrible signal on the first day, once I did ##DATA# it fixed it, but my battery life is sucking it up badly.
Sent from my bathroom, with toilet paper.

Just got my wife a shift earlier today and ran it down from the half life that came with the battery in about...6 hours. That was with near constant use, the screen on max, wifi, and sync. Plus GPS on for awhile too. Compared to my epic which with similar use can go...maybe 6 hours from full? It depends. I'll be comparing her battery usage to mine over time and I'll post after she gets some use from a full charge. Under normal usage I can get up to 28 hours from my Epic so people reporting horrible battery life must be doing something wrong or have a defective battery. I fully expect her to get a couple days life out of each of her charges though she'll probably throw it on the charger every night.

anyone have an explanation of why the screen is the largest amount of usage under battery stats? yesterday was an average day for me and the display was something like 50%. on my Evo cell standby was always the highest and the display was down around 8 or 10%
edit: this morning the phone has been unplugged for an hour and a half and cell standby is 50% and the display is 11%... *scratches head*

I just switched to Sprint a couple days ago and got an EVO 4G; I am really unhappy with the battery life and though I got them to give me an extended battery for free it still seems like it's dying very quickly. I am a heavy data user and it's driving me crazy; does anyone have any experience going from the EVO 4G to the Shift and, if so, what are your thoughts, particularly in regards to battery life? Is it worth the loss of size and cameras?

i went from the evo to the shift (30 day swap deal) and i haven't even looked back. the battery life is STELLAR as far as i'm concerned. the evo sucked down power like nobody's business. i'm sure if you got an extended battery for the shift it would last you 2 days at least.

All I gotta say is my extended battery experience is amazing. I get about 36 hours out of my evo. Yea it looks a little fugly now but fck it I can abuse it as much as I want too with battery to spare.

I just got the extended battery and haven't charged it overnight yet, but so fast I am very concerned that it is not living up to expectations. However I won't make any quick judgments until I've seen how it does over a couple days.

My Hero got better battery life.
Sent from my PG06100 using XDA App

Typical use for me is pulling the phone off the charger at 5am, light to moderate use throughout the day (texting, facebook/twitter, apps updating ~2-4 hours, etc) and then putting back on the charger at 9pm.
I upgraded from the Hero. The Hero was rooted and running AOSP w/ modified kernel and collin's battery tweak. Battery life was impressive, but performance was an issue. I could routinely get 30+ hours battery life with the type of use listed above (battery was usually 50% or more when I'd put it back on the charger).
With the Shift, battery life is surprisingly good. For some reason I lose ~10% within the first hour, but after that, it seems to settle down and by the end of the day I'm still at ~30% (with the type of use listed above).
Based on what was possible with the custom ROM's and kernel tweaks for the Hero, I'm excited to see what the community can do with the Shift once we get root.

That first 10% drop seems normal for the new HTC phones. I know the Evo does the same thing. Just the way they're charging the batteries

I found this article helpful in understanding the ~10% dropoff when first off the charger.

At what setting do you all have your screen brightness set? Do you use the auto-brightness option. I find consistently that the overwhelming majority of battery use (according to that screen in the settings) is from the display.

What's your Battery mAh calculation?

For those unaware, there is an app (Battery Monitor Widget) that estimates your mAh based on the current sensor for any continuous charge over 50%, larger being better . It's a nice alternative to all the "what's your SOT / battery life" threads where everyone has different usage patterns, signal quality, brightness, etc. Though it's not the full story as variance in chips/screens can yield different power usage. Though you can also compare the % drain / hour in different situations.
https://play.google.com/store/apps/details?id=ccc71.bmw
Automatic mA retrieval seems to work fine (selects the S6/Note 4 method), and a recording interval of "Every minute while charging (accurate mAh calculation). After that, all you have to do is charge your phone when it gets low on battery and look at the calibration tab.
I've used it on other (used) phones and it seems to give somewhat realistic numbers, but never a new phone/battery. Anyone else's past experience with this is welcome. It's been quite helpful in buying 3rd party batteries and used phones as it's a real estimate.
Definitely important to have a baseline comparison with other identical devices so you can see what's normal and what's typical measurement error on each model.
It seems to work best if you don't use the phone at the same time, otherwise it underestimates. Overnight non-wireless charging works best. Basically, when you use the phone or charge wirelessly, more of that current goes to heat causing underestimates.
I'm only finding reasons for underestimating, so I'd still generally trust the highest couple calculations within the past month, unless the model just doesn't report current well.
FYI the phone actually pulls more current than a non-stock USB charger on load, so I had to let it charge to 2% after the phone turned off in order for it to survive boot-up.
My measurements after the first one are pretty consistent so far:

I think this app doesn't work properly with latest samsung smartphones.
I had two S6 edge+ that should have a 3000mah battery and the calculated mah was allways between 2400-2950mah.
Otherwise this app worked properly with my S4 or note pro..

There is one report that it's accurate for the S7 non edge
https://www.reddit.com/r/GalaxyS7/comments/4bmg3z/whats_your_battery_mah_calculation/
Did you use the phone during those 2400 estimates? Due to the variance it's probably best to believe the highest number, in which case your 2950 is quite accurate. I'll have to run mine again.
It's been quite helpful in buying 3rd party batteries and used phones as it's a real estimate.

I tried every setting with the s6 edge+ and allways charge the device from a minimum of 20-30% - 100%
This app was so inaccurate that i deinstalled it and since then i use only gsam battery monitor.
I don't need to know the exact battery capacity even if this app would calculate it right.
It makes me crazy because i allways thought my battery is faulty and it was one of some reasons for me to buy another s6 edge+ but there were the same results..

Definitely important to have a baseline comparison with other identical devices so you can see what's normal, sucks that you had to buy another one to get that. That's basically the point of this thread, to get a baseline and understand what's normal, but also find out when you get a faulty one that deviates from everyone else's.
I wouldn't call it inaccurate, you said yourself it measured 2950 out of 3000 mAh, it's just you didn't know how easily it can understimate under load and other conditions. It's actually an invaluable tool when buying 3rd party batteries and used phones to get an independent capacity test.

Take a look at this thread, #267.

If everyone in your model family gets the same variety of measurements you know you're fine. If everyone consistently gets a higher value, then you know you have a potentially weaker batter.
Not saying you do, but those measurements are what my wife's phone looks like who uses it all the time on the charger or has bad signal / high drain. When she doesn't, she gets a measurement close to the real capacity, that's why I said yours seems accurate as it has some measurements around 3000 mAh.
In addition, batteries loose capacity sitting on the shelf, so there's always the possibility of it coming with a lower than the full capacity

Ok, i never used it while charging but maybe it was because most of the time i charge wirelessly?

Ah yes good catch, that could be it. Also other things like the automatic updating of a bunch of apps, or some other strenuous synchronization. I was just reading this:
http://batteryuniversity.com/learn/article/what_is_the_c_rate
When discharging a battery with a battery analyzer capable of applying different C rates, a higher C rate will produce a lower capacity reading and vice versa. By discharging the 1Ah battery at the faster 2C-rate, or 2A, the battery should ideally deliver the full capacity in 30 minutes. The sum should be the same since the identical amount of energy is dispensed over a shorter time. In reality, internal losses turn some of the energy into heat and lower the resulting capacity to about 95 percent or less.
Click to expand...
Click to collapse
So basically, when you use the phone, more of that current goes to heat, and I think that's also true for wireless charging: both possibly underestimating the capacity.
Nevertheless, I'm only finding reasons for underestimating, so I'd still generally trust the highest couple calculations within the past month, or some models just doesn't report current well.

My measurements after the first one are pretty consistent so far:
https://imgur.com/jOzHQQB
2943, 3400, 3421, 3356

So I've stopped caring about careful mearuements, use it on the charger, do shallow charges, and it actually still seems to be very consistent on my S7 Edge (my previous phones has estimates with larger variances).
