25 min cost 27% battery

I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.

There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.

I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.

You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.

The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.

There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.

I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.

Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.

You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.

2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...

i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.

I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it

Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge

[Q] Help with battery usage / drain, how to increase battery life

Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.

How many hours is your phone lasting on a single charge?

Lately between 5-7hrs one had about 8 and half hours a handful of times

it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later

This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?

I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol

Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.

Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!

Quick battery drain & constant data being sent since 1.78 OTA

Hi,
I've got an HTC One S since a few weeks (got it with the 1.57 FW I think). It's a stock one, not from a carrier. No branding.
The battery life was great, 2 to 3 days with normal use.
But yesterday evening I proceeded to the OTA update and since then, trouble began
Battery life is much, much lower. After 12 hours standing on my desk in the office, I got 10% remaining!
Anytime I switch the screen ON, I see there is some data being sent (or received) because the "arrows" are full. If I check in system panel lite, there's always 1 or 2 kb/s of traffic.
Also, the phone is a bit warm, quite often.
Has anyone else noticed this? That's rather annoying :/

Could be faulty? I have the same phone with no carrier or branding and not had any problems at all.

Like faulty hardware? Seems unlikely to me since it worked well with 1.57. Also, sending data isn't hardware related

Here are some details.
In Mobile usage, just for today (less than 24h)
"Media" has used 13MB of background data
"Android OS" has used 5MB, also background
Android OS gives no more details. Media is told to include "Download manager" "DRM protected content storage" "Media storage" and "Downloads"
This sounds like a lot of background data :/

Try an app called Badass Battery monitor. It should tell you what's eating your battery.

I have to say, this phone, at least mines, seems to have a pretty bi polar battery. It's got a case of ADHD.
For example, just the other day, I had the phone fully charged when I awoke at 9am, after playing Temple Run, surfing the web, using GPS, streaming and listening to music, playing more Temple Run, fiddling around with the OS, checking emails, sending texts, talking on the phone a bit, downloading apps, with about 25-30% brightness, I ended up with 18% battery remaining after a good 11 hours of very heavy use. I was quite pleased, considering the inordinate amount of usage I had with the phone all day.
(BTW, I use Juice Defender, which has helped tons in reducing battery drainage for almost every phone I've owned in the past 3 months, including the One S)
Yesterday, I had the phone charged at 100% when I awoke at 9am, with a little bit of use, by 12am, I had 63% remaining, same brightness, but with much much less use then the day prior. By the time 3pm hit, I was at about 30%, and by 5pm, it was drained to 18%, mostly on standby. By my estimation, that's 8 hours of usage, same brightness levels as the day before, using Juice Defender, but with much much less fiddling around with pretty much everything on the device.
I went ahead and disabled Juice Defender today to see if it would make a difference, and the battery actually got a bit worse, so I went ahead and re-enabled it and it immediately improved.
So I'm a bit perplexed, I haven't gotten any official updates, still running on the original stock build, but ultimately, I guess this is what is too be expected with an early build. Hopefully future updates WILL fix these issues and not hinder them more. Granted it's still much better then my HTC Amaze and Galaxy Nexus, which drained 4% the moment I took them off charger.

Thanks for your input, I'll check again today how the phone goes.
I played with all the settings and menus yesterday, and found something strange. In the "downloads" app, there was a "system update" download. That's quite normal since I downloaded and applied the OTA the day before. But it was referred as "ongoing", like it was still downloading a part of the OTA zip file AFTER I applied it (and rebooted a couple of times)
In phone settings, about, updates, it was also written "ongoing"
Now this is over (I don't know why and how) and the network usage seems back to normal. I'll try today to see how the battery drain is
Anyway, it's s strange the phone was still downloading the update zip file after having applied it. AND that it was downloading it on the 3G at a very lowered bitrate (like background) while I downloaded it on the wifi the day before
Anyway...

The battery life of my One S seems to have declined as well since the update. Before the update my battery lasted 2 days easily with moderate usage. Now I have 20-30% left at the end of the day from a full charge since 9am. This is with very light usage (mostly on standby from 9 to 5).
I did turn on best wifi performance recently so I just to turned that off to see if it helps but I really doubt that.

Hello guys, I have same problem, but my phone wasting energy on "phone radio" process, just look at screens below. I tried using stock Rom with last update, trickdroid, and now it happend on leedroid v.2 . Btw I changed 4 micro sim cards with several providers, but no result. I really need help with this issue, because my battery draining very very
fast...
Thank you

I had a similar problem a few days ago, using Lee´s ROM.
I noticed that the drain had something to do with autosync. As soon as I turned off autosync (leaving mobile internet on) drainage went back to normal.
I still don´t know what caused this since I only had the google account, weather and dropbox installed.
Anyway, after doing a fresh install, the problems seem to have gone.
Of course I can´t be completely certain of it until some more days of testing/usage.

I also noticed quite a few problems since the latest OTA update.
Not only does the battery drain fast, the phone also feels extremely hot when browsing on 3G.
The phone does cool down pretty quickly when turning off 3G but it feels like I burned my hands
Here are a few screenshots.

I also experienced weird things when connected to EDGE (2.75G).
3G (HSPA) coverage on BASE (KPN) sucks in Belgium
Look at the video below for more details.
Has anyone else experienced this yet?
http://youtu.be/3g8FLpWDAYM
I also contacted HTC about this issue and they recommended a hard reset.
Unfortunately this doesn't help at all, I still get these weird glitches

mattionline, can you get a logcat when the phone's doing this weird stuff? It looks like the Home button is being pressed repeatedly and if logcat confirms it then it's probably a hardware problem.

I just fixed someone else phone that had the exact same symptoms. In the end I narrowed down the problem to one of his weather apps.
He had a live wallpaper that reflected the current weather, weather on his lock screen and a beautiful widgets weather thing. I never did figure out exactly which one it was I just turned off all there and told him he was crazy.
I don't know if it's something "weather" related for you but it maybe it will help.

you don't need root, just enable usb debugging in development options and connect the phone to your pc. You need to have the android sdk installed.

Sup guys , some of you don't seem to realize that there are many reasons why your battery drains, what you might think is, "quickly". A few tips to keep minimal battery out put...1 keep brightness down, the screen itself sucks juice probably the most. 2 check your apps, some apps send and receive data and/or are kept running in the background. You might have to enable/disable setting on shove apps. 3 widgets, widgets like battery meters, CPU meters, things like this constantly refresh to keep real time info. That also eats up alot of juice . 4 Turn off WiFi or any other thing like that when your not using it. WiFi continually sucks nice. Lastly, invest in some app that will help you close apps. Basically, tweek everything you might think that the os can run without. The less your CPU has to do, the more juce you save.

This made me lol hard.
Best advice ever.
But yeah, on the 1.0 version of Leedroid I had quite some drain, too.
When I turned off autosync it went back to normale. I only had my google account, dropbox (with syncing off) and the weather thingy set up and never figured out which one was resposible.
After installing Lee´s 2.0 ROM everything is fine.
I suppose there really is something wrong with the autosync and maybe with the weather stuff in particular.

My problem didn't go away with stopping auto sync, even without it, I had a constant data flow
Anyway, I rebooted the phone twice and the issue was gone.
It happened again a few days later, after the phone did shut down because of low battery. I put it on charger and turned it on, then, I noticed the 3G arrows were always on. After I unplugged it from the charger the battery went down in 10 hours. After a reboot, problem gone...
Since then, nothing...

And please note than when the problem is here, it's media and android os using a lot of data

I have been having one S problems too - I am on my second phone after the first one became reliably unresponsive every time I turned on mobile data. More relevant to this discussion, my battery died shockingly last night. Normally it drains at a few percent an hour when I am not using it (i.e. when asleep!) but I woke this morning to find it totally dead - that is 30% plus gone in 5 hours without it being in use.

Am I the only one with poor battery life?

I can't get through half the day.

could you be more specific as to what you do on your phone? is your phone the international version or the USA T-mobile version.
Sent from my Transformer TF101 using xda premium

Tmobile, stock everything and I had the battery issue on my first HOS. I just got my replacement and Im running the same apps, same calls, same eveything as the first phone but i get a significant more battery life. The battery on the replacement HOS lasted me the entire day, but I still carry a charger around just incase.

Superbattery?
My TMo One S battery life recently went through the roof for some reason. I can only attribute it to one of the following or perhaps luck:
I've been charging it at end of day regardless of charge but I finally let the charge get below 25% -- I think it got to 15%. Then I powered it down and let it charge 12 hours overnight.
I disabled all Facebook related apps.
Other than that I can't recall anything I did recently that might account for my new super battery. But I'm at 1d 4h 25m on battery -- most of that on WiFi granted -- and still have 42% juice. I'll take it!

I always have my charger because I'm a twitter whore. I recommend disabling any bloat ware or duplicate app like Facebook For HTC or Twitter For HTC. And make sure you change settings for each app you use and don't use.

Anyone use Juicedefender? My battery is excellent but if it can be improved then even better..

I'm using my phone very much, with Facebook and games and such, and I still get through the day without hesitate! I think it's wonderful

my battery life was poor on stock rom aswell. went trough a day only. had to charge every day. but now with noble v3 rom and being tiny bit more careful with use i have battery for 2 days

Battery life on this phone is better than most and I give it that. The only problem I have is the quick drop from 100% to 92% in a hour from little to light usage.

That's with quite a bit of texting, pics taken at work, and 45 minutes of web browsing while I was on lunch. Granted, I don't do Facebook, so that may help.
This is the first phone I've been lazy about rooting because it's worked so well so far.

I get decent battery life as well, but how do you manage only a 25% drop with over 12 hours of on time whic included a bunch of texting which keeps the screen on while u text and 45 min of browsing. Seems too good

I just got my One S less than a week ago. Love ICS. Battery life has been about 10 to 12 hours with medium amount of use. Facebook is disabled. I'm using active sync to sync to my exchange server and push frequency. (that continually goes out but that's for a different thread I guess).
I charge over night as I've done with my Dinc2, original Dinc, and all flavors of blackberry.
Last night I used a digital clock app while it was charging and in the morning at 8:30 where I unplugged, it had 100%. It's now just past 11 in the morning and with email, one short phone call and some light surfing, I'm already down to 62%.
I have noticed the phone is hot which means it's working hard to do something.
I have WiFi off and GPS off as well as location services. Should I return it for a new handset? Should I just go back to Verizon and get an iPhone?? Ugh.

What's your "screen on" time? Have you changed any connectivity settings, that may have increased your battery life a lot?

If the phone is hot then something is running in the background you should probably figure out what that is and disable it before you do anything. Now with exchange servers set up on your phone they do tend to eat some battery. That's universal though. Sounds like to do have a rogue app though. As for me this past Monday I took the phone off the charger at 430am and didn't have to return it to the charger til 11pm mostly because I was going to bed. I watched netflix, text, phone calls, Web surfed.... Love this device.

To you and the other person that asked, I think it really has to do with cell signal strength.
I posted those numbers after coming home from work where I have awesome cell coverage.
Today I've been home all day, and even though I'm on WiFi all day, my cell signal is horrible here. WiFi or not, it's still searching for a signal constantly so I've lost 30% in 6 hours with moderate use.
Now, as I said before, I don't use facebook or friendstream, but I think a lot of it is the radio constantly searching for a better signal.

I also think that either bad signal or just 3G takes a lot of battery.
I switched to 2G only just as an experiment, where I get a good signal almost constantly. This extended my battery life quite a lot. Where I usually had 10-20% left after a full day, I had 50% left with only 2G. I have also been using WiFi where available.
Can this be a software bug since there is such a big difference? I've noticed before that phone calls suck a lot of juice...

2G is known to use much less battery life in every phone you check it.
Take a look at GSMarena on phone specifications in the bottom and you'll see the great difference.
BTW, looking on the battery test GSMArena did for the One S, it's quite in good place for the 3G calling and Video playback but uses a lot of battery on WEB browsing, see here
Might be that we the ones with low battery are more surfing than the others...

I get about 24 hours.
2 hour screen use. No FB or twitter, only gmail sync
Some text, 5mins of calls, <2% no signal
When idle i get battery drain of <10mA using:
http://www.3c71.com
Battery Monitor Widget. Logging current consumption is the only way to get to the bottom of the problem.
I'm talking with the author to get the kinks worked out of the One S logging.
*but* for some reasons something is keeping the phone awake at times. current drain is then 70-80mA constant. Not been able to find the culprit, but a reboot helps.
Hopefully this was useful.

I had the same issue-downloaded 2x battery from the market and it is much better. ( I have syncing with twitter, fb, gmail, mobile life all enabled)
I could barely get through the day. Seems the phone does a lot when syncing etc and this stops that, or at least limits it to the interval of your choice. every 10 I believe with the free version.
Try it-I am sure it will help. (I also turn the brightness down as I am mostly indoors-and put it on auto outside-but that is just me)

Actually, due to the fact that every time I check the usage of battery screen is in top place (with Auto brightness all the time) and the fact I'm syncing with FB, Gmail, Exchange server and more, I guess the best thing to do is to lower Screen brightness...

Battery drain issues: last attempt - with screenshos and dumps

Hi guys,
I am hoping someone may notice what's going on with my device... I am at a loss. Attaching all screenshots and dump file from BetterBatteryStats (may need to open in Wordpad for the spacing work).
To summarize, my battery drain is very inconsistent. Some days it lasts a long time, 2-3 hrs of screen time, can stay in standby for over 2 days. And then some days it drains very quickly, like right now - it drops by 3% every time I basically turn on the screen to check e-mail/messages. I think we can all agree that 4 hrs of standby and 15 mins of screen usage should not use 50% of the battery.
I have tried two different units (swapped thinking my battery was faulty), and the issue persists - so I think it has to be something related to my software setup. I am running the AT&T LTE stock phone, 1.85 firmware. I have tried doing the full factory reset (clearing all settings/apps/storage), and cycling the battery.
Some folks have mentioned that my drain seems to begin when I hit an area with low/no signal (I take the subway to work in the morning), and then persists - as if something is trying to sync/connect somewhere, but can't... so it keeps looping and draining the battery.
My autosync is only on for Gmail, Google calendar (not contacts), and Weather (every 2 hrs only). Phone is not overly hot, battery is at 86 degrees right now. My brightness is at 40%.
If someone has any ideas, please share - I am at a loss, I don't know what to do... but battery life has got to be better than this, at least in terms of consistency.
Thanks so much.

Little to no signal is a battery killer.

Right, but the phone drains like crazy after the signal is regained. It doesn't drain much while there is no signal. Besides, what are people supposed to do when they lose signal? Restart the phone afterwards or lose all battery?
Also, some days it works just fine (and I still take subway to work on those days and lose signal) - so not consistent. I don't think it's simply the fact that no signal kills my battery in this case.

But OP is getting huge drops in the battery level when network signal is green (full signal strength); and also screen mostly off. Which is very odd . . .

Sounds like there are other folks experiencing this issue, related to signal drop in LTE (riding a subway, etc.):

Step 1: Remove sense.
Step 2: Proceed to experience the best battery life I have ever seen on an Android device.
If you do not want to remove sense then you need to take a very close look at your apps because something in the apps is responsible. I personally think its HTC sync or some other rediculous service that comes preinstalled on the phone. Something is trying to sync or communicate and is hanging.
Like I said, get rid of sense and save yourself the hassle. Nova Prime + AOKP = the best mobile operating system known to man.

I am a bit new when it comes to Android and all the various ROMs out there. To remove Sense, do I need to unlock the bootloader and install a custom ROM? Or can I install an alternate launcher (like Nova Prime)?
Thanks!

To remove sense you'll need to install a custom ROM such as AOKP or cm9. Those will remove sense. You can find AOKP in the general section under the title "AOKP lives!!" and cm9 under developement. They both have flaws such as the camcorder not working, but considering the flaws that sense has out of the box, you're much better off in my opinion. cm9 and AOKP will get infinitely better in the coming weeks as they iron out the bugs. Sense is disgusting bloatware that is piled on top of stock android. It takes a ton of resources and makes even the simplest tasks a chore. Once you go to an AOSP ROM I don't think you'll ever go back. I can multi task away for hours and come back to another app that wasn't closed out of memory. Try that with sense.
To install a ROM you'll need to:
Root
unlock bootloader
Install a custom recovery
Backup your entire ROM with that recovery
Flash whatever you want
All of the directions of how to do this are in the dev section. Let me know if you have any questions.

Installing a AOSP ROM (such as CM9 and AOKP) will completely "desense" your phone.
Installing a ROM based on stock (like all of the CleanROMs) will get rid of most of the HTC stuff but Sense will still be there.

Thank you seh and rohan, I will give that a try. Will read up on it and let you know if I have questions.

Seriously just go check it out in the dev section. If you are unsure or have any questions at all come back here and let me know. I can walk you through all of it. Don't be afraid of ruining your device or anything like that. This stuff is all one click these days and isn't bad at all. I can literally walk you through every step if needed. Just check it out yourself though, I bet you'll be fine

Thanks again. Reading through the dev section now. Seems relatively straight-forward... just need to get home to get this stuff going.

FYI, the root process failed for me 2 times before it took. Just keep trying and it will go. Once you are rooted, you'll never have to plug your phone into a computer again. You can do anything from the device, no questions asked.

Here is what I'd do before installing custom ROMs etc. (Not that I am discouraging you against that but, if your device is indeed faulty then unlocking the bootloader will void your warranty and HTC may not replace/fix it.) And, you'd have wasted countless hours trying to fix the issue with software that was hardware to begin with.
1. Run the battery test *#*#3424#*#*, press 'Accept', Go to More and run 'Battery Test'. Follow instructions in there. If the battery isn't faulty i.e. after one hour the battery level is still greater than 85% (The function test shows a different number) your battery is fine. Else, ask HTC to fix it.
2. If your phone passes the battery test; turn on 'Airplane mode' when you get into an area with spotty signal. This should address your suspicion regarding that.
3. Display: display seems to be draining the most battery - doesn't mean it actual does but, at least the phone seems to think it is. Try reducing brightness to around 20% for a day - I know it is too dim but, it will eliminate that possibility.
4. If you have facebook installed - turn off all syncing. Especially the HTC sense social plugin always tries to update it from facebook.
Based on the screenshots, it seems that the battery drains very quickly when you have the screen on, even with good signal strength.
Lastly, as an alternative to point 2 above, turn on airplane mode for 1 hour and turn off sync, remove all widgets from home screen(s) and just use the phone on wifi with stock browser - see if it drops as quickly or not.
Having gone through it, I understand how frustrating this is. In the end, I rooted and completely desensed my phone (only keeping essentials - basically recreating clean rom). I do not use Auto Sync but manually engage it every few hours to update everything. And, keep the brightness to 30% most of the time.
Hope this helps, good luck.

john_tillman, thanks for the suggestions as well!
1. I did the battery test, finished at 92%. So I think I'm OK there.
2. I will try doing airplane mode before subway rides going forward, will see if that helps.
3. Something is funky with the way the battery meter app is measuring this. Basically the battery doesn't move - and then when I unlock the phone, it drops like 3%. So my suspicion is that I'm losing battery, it just doesn't get updated until I fire up the screen.
4. Yep, all syncing is turned off. I only have Gmail/Gcalendar syncing now.
I've been playing around with the phone(s) earlier as well - keeping it in airplane mode and just watching movies/etc. makes it last forever. It really does seem to be something with the signal and perhaps something in Sense.
Have you tried CleanRom? I do like the visuals in Sense, would be sad to go to bone-stock ICS... but battery is more important.

I experience the same thing. After my subway commute and after I regain signal, battery doesn't drop until a couple of seconds after o turn on my screen, but it drops like 3%.

Rooting, and unlocking the bootloader
I was able to go from stock 1.85, to sick-sense ROM in a matter of minutes yesterday. I was nervous at first even though I know what I was doing, although all was good after following the instructions given on each step of the process. I haven't really bricked a phone before because this was my first smartphone ever, But I believe that the worse thing that can happen is soft bricking your phone, which can be resolved by RUU. I hope this helps you out.
Regarding OP, I had MUCH MUCH more battery life compared to bone stock. I used to get 3 hrs screen on time with 20% brightness, now Im at 4-5 on 50% under similar usage. One last thing to note; LTE, Auto sync, GPS, and low reception, are the most battery eating thing on the phone assuming you don't have rouge apps (wakelocks).

GPS has no affect on battery life unless it is being actually used. Its not going to drain battery just by being enabled. Auto sync has minimal impact on battery as well, unless you are getting 5 emails every 1 minute. Push is always more battery friendly than pull. (unless there is heavy traffic)
About the low reception thing. While it does indeed affect battery life when the phone is constantly looking for service, it is not as bad as you would think. I sit in an area at my work that has about 1 bar of service. The phone will go from 1-0 bars to searching, about every 5 minutes or so ALL day long for 8 hours. To see the impact this had on my battery life, I did some experimenting. I basically ran my phone in airplane mode for 3 days and then compared and averaged the results over 3 days of normal use with the phone having bad service.
I lost 8% more over an 8 hour work day.

No, I didn't try clean ROM. But, I took the change log from one of the clean ROMs and deleted most of the apps that can be safely deleted. So, I do sort of have a clean rom and it works fine so far - in terms of battery life. When I used to boot with stock rom, I used to have 150 - 170 mb free ram. With the clean up that I performed - now, free RAM is 270 - 300 mb after a reboot.

Try disabling LTE and see how your battery does.
