[Q] New GS 4G user. Help with battery problems.

Love the phone. Only complaint that I have is the battery life. I only get about 10 hours of normal use before it dies.
I have it rooted and I have installed Juice defender and setCPU. I have no idea really how to use either of these apps though.
Can anyone please help me to install and set up the apps that I need to get the best power/battery life ratio for this phone?
Thanks.

A really helpful tip is to use black backgrounds. This reduces the amount of pixels on the screen requiring power on the Super AMOLED display, and will improve battery life significantly. Tower reception is also a big one, just turn off mobile data when you get to a low signal area.

I suggest turning down the brightness to the lowest indoors and then bringing it up a little outdoors. 10 hours is really good compared to the 4 hours I got on my old 4g.

I second the black background.
I also installed widgetoid, created a widget with a shortcut to the mobile network settings.
I have Network Mode set to GSM only (Edge Network) throughout the day. This is fine to keep my email syncing and for phone calls. If I know I'm going to start browsing the internet/ streaming music/ etc then I go and set the network mode to Auto to allow 4G connections.
With a few phone calls and a little bit of internet usage I still had about 60% battery life left after 12 hours off the charger.

juice defender works wonders. Set profile to extreme. Choose carefully and let app do this rest. It auto shuts off data when not using 4 apps. I have been off charge 9:40 mitutes with 79% battery remaining. I've been on the market made a few phone calls, browsed the internet and getting and receiving text + emails coming in. Have settings GSM only until I need 4G speed. I don't need a charger because I get through the day easily.

Thanks
I just wanted to say thanks everyone for the tips! I know more is coming from other users but i'm new to android i switched from Windows Mobile 6.5 and android is better so far or atleast for the week i have had this device. i was getting upset with the battery life and always taking my charger with me(i never had to do that with my custom Rhodium. the black backround idea does work very well. I have also found if you set your backlight timeout to 1 min it helps a lot.

you call 10 hrs a problem??
I can tether my Xoom for 2 hrs and listine to pandora over bluetooth for another 3 before it dies... my last phone could berly stand 45mins of pandora over bluetooth before crapping out

Always hated the idea of black backgrounds on beautiful 800x480 screens. Anyhows I had the very same quick battery death too and fixed it. One get Juice Defender, very worth while, second run device in portrait mode [I was an old n900 user so I had it in landscape mode, it did not like staying in that mode]. If things get really bad turn off the WiFi when not in use and change the autosync features to off or disabled. ALOT of power is comsumed by adware communicating with various entities while your away from the device. Genuinely suprused by the sheer amount of adware on the device, nearly ever "free" app is adware [meaning you pay with your usage pattern's etc]. YMV but that all I had to do to get the battery under control.

Im a moderate user and my battery is still going strong

Yep, I'm more than happy getting 10-12 hours of at-office use with WiFi on constantly (including M$ push and personal email) and a moderate amount of browsing during the day. I keep the brightness at "0" as much as possible.
Beats the pants off my N900 which would die in under 4 hours under the same at-office usage patterns.
OEM battery and charger is ~$25 or a Zagg Sparq2 (4 Ah, I believe) for watching hours of video and Angry Birds on those trans-Pacific flights.

You are doing something wrong guys. . .
I'm on a Vibrant /w Froyo 2.2.1 and a 1500mah battery that is now 7 months old.
Battery left says total battery life per charge is 23 hours, 15 minutes.
Now mind you I am a relatively moderately/heavy user. I have 5 homescreens with 15 widgets total on them that refresh every 2 hours, and an intensive live wallpaper.
I use the phone a lot for reading RSS feeds, facebook, texting, and LOTS of music. Total screen-on-time per battery charge is around 3-4 hours with Automatic brightness.
Obviously you have something going on with your phones if you are only getting 10 hours. My phone is also overclocked to 1.4Ghz with overvoltages and I STILL get this good a battery life with all my usage...on an old battery mind you.
Check for rogue apps?
PS: I have Wi-Fi on 100% of the time but NEVER use 3G/HSPA for data since I don't use a data plan. The Wi-Fi is connected 90% of the time the phone is on though since I am always at places with Wi-Fi.

Getting great battery life on my TB... :)

Keepin' it clean by keepin' smooth...
Ok finally after a few days of using my phone it has finally leveled off. My phone has been off the charger since 6am and I am at about 70% charged. Couldn't ask for more out of a smart phone. This is right in line with my Nexus One so I am no longer disappointed.
There are a few tweaks I did make to get this working this way.
(1) Screen brightness set at about 20% - The TB's screen is way to bright to begin with and making this adjustment is something that is not very hard to get used to.
(2) Screen Time out at 30 seconds - Setting to low will get frustrating if you like reading the news on your phone or browsing the web, 30 seconds seems just right for me.
(3) WIFI when not in car (triggered on and off by loss of Blue Tooth Connection and Not In Dock) Using WiFi instead of relying on your data connection will help save some juice while in a WiFi enabled building since your phone will not be trying to constantly search and connect to a data connection.
(4) Blue tooth off until docked - Saves battery by not transmitting a BT signal constantly. I only use Bluetooth in the car so triggered by the dock seemed logical.
(5) Syncing Facebook every 8 hours, News every 12 hours and Stocks (Who really needs this)
(6) I love widgets on my home screens so these get updated as I found necessary to me. Im not a major facebooker that needs to be on the bleeding edge of everyones life so 8 hours is probably even too much but adequate. News doesnt really update very often and compared to a daily news paper 12 hours is more than ample. Stocks, need I say more seriously I am not an investor and could care less.
(7) Over clocking your phone is not necessary right now, 1 GHZ is definitely more than you need on this phone. I am scoring about 1700 on quadrant which is pretty good for a 1ghz phone. My phone has never lagged and has functioned as expected since birthed to my hand. Keep in mind Over clocking will increase the performance of your phone but will tear at your battery as well and may cause heating issues.
(8) Not using an animated wallpaper. Even on my nexus one this was a major contributer to poor battery and phone performance. Animated wallpapers are very often poorly programmed or simply over bloated. Not too mention on the severe end of the priority list of needs. All though cool.
I am not over clocking or installing a custom rom on my phone quite yet because honestly the roms are not stable enough as expected this close to birth, and really don't offer any additional functionality that I find very useful as of yet. I am using Tasker to accomplish a few automated switching routines to toggle WIFI and Bluetooth. I am also using Folder Organizer to keep my apps categorized in a humane manor. I am a widget-aholic and have not really found a downside to having too a lot of widgets running.

How much do you use your phone a day?

Not everyone is willing to cut out their social networking. A big part of smartphones now is always being connected. This includes social networking, sharing pictures, sharing locations... some people get into all of this and some do not.
Also, some people like weather updates, stock updates, news updates, etc. Everyone uses their device differently to fit their needs.
I think it is common sense that the more services you use which consume radio/data/processing time then the quicker you will drain your battery.
Thank you for sharing the setup that works for you and affords you such great battery life. I have been having great battery life too. I am currently not in a 4G LTE area, but the device on 3G has been great on battery. You would never know there are any "issues" if people did not post about them!

What is your uptime, display on time, and partial wake usage?

I didn't check that deep in to it, but I had it plugged in to some speakers at work for about 3.5 hours playing slacker radio from wifi so I could rock at work. I used the phone to call tech support for my wifes phone which took a while and other shorter calls through out the day. Right now my up time is about 65 hours, awake time is at 26 hours. Not sure where to get partial awake. My display on timer only says 1 min. But honestly today was not a big phone use day and it sat in the dock on the ride home so all those stats are irrelevant today. But still my battery it at 83%. A lot of people were complaining about there phones dying with no or little use half through the day. So hopefully this brings a little light to the end of the tunnel.

Dang what were your settings

I have basically the same things running on my phone. Only, my folder organizer keeps fc every time I attempt to edit a folders contents... Anyone have a suggestion?

I've been getting great battery life as well, got 36 hours on my last charge. Have Perfect Storm 1.0, trip's 1.5ghz oc kernel (but don't actually run it that high). I have SetCPU set at 998/245 for normal, 245/245 for screen off and use smartass governor. I was also using my phone a moderate amount but had the 4g turned off as I'm in between 3g and 4g so it just keeps dropping and switching.

Glad to see someone is getting decent life.. I'm about to set a record for battery death.. phone has been on for 1 hour and 20 minutes and down to 65%.
On the bright side I am getting 20mbps down here at school.. SDSU..

Do you have it on LTE only mode?

Yah.. I am surfing pretty heavily though.. down to 58% now..
Guess ill have to sit in a different seat for the rest of the classes.. I see power outlets along the walls
It sucks though because on the Droid x, I could surf during the whole 3 hr class and walk out with 50% left.. guess this is the price you pay for this kinda power and speed lol

from 6am to 2pm phone is dead
music for a hour and half while on airplane mode
3g only
gps,bluetooth,wifi off
half hour of web browsing on 4G
about 15 messages on live Profile app
about 40 text messages
auto sync and background data off
One thing I dont understand is..When my phone is idle the battery is still draining.

6am to 6pm...
3g only (off when not using it)
gps,bt, wifi - off
games for about half an hour...
a couple calls
>20 txts
screen at 15%ish
autosync and background data off...
and now i'm at...89%
I have also found that in the first couple of days (2 or 3 days) after a reset... the phone does a BUNCH of funky things. First night after a reset...VZwireless said at 3AM i had 130MB of transfer... not possible - i was sleeping. it wasn't me. but...i did wake up with >30% of the battery gone. I think the background data off is a good place to start...but definitely wait after a couple of days.

I seem to be getting about 36 hours of up time on a charge. Mostly on wifi at home/work. I have 4G turned off as its not available here yet.

Ok.. 4 hrs .. done for ... Did make it through class.. 8% left

There will be a patch soon to help with the idle 4G battery drain. Lady on the phone told me its in the works. Either way I just got the extended battery today. I actually dont mind the extra size.

Hmm... whats the anecdotal battery life for an extended battery given these settings? I've gotten to the point of running my display at 5% when indoors ==;;;
Also, I've heard of people getting free or heavily discounted extended batteries.... Any tips for this?

I am using an app called fastbright which really helps with the display battery drain...I just use it o bright when i cant see if i am outside....post #10!!! yay!

I've used my phone a decent amount today and battery is still at 62%. Running Das bamf at 1.2 ghz and screen brightness at 100%

[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!

[Q] Awful battery life - just me?

I got my Nexus 5 on Monday and have been pretty happy with it so far. Today was the first day I actually had to be away from WiFi for the day and the battery life has stunned me with how poor it has been. I haven't seen battery drop so fast since I had my Desire HD. I took it off charge about 9am and at just after 8pm as I type this I'm down to 10% with under 2 hours screen on time. 100% to 10% in around 10 hours with less than 2 hours screen use.
Has anyone else had this poor battery life? I'm going to let it run down completely, install GSam and see if it happens again but from what I've read on a few reviews (The Verge was the main one) this seems to be almost normal. I would be unhappy with battery life this bad after two years, not two days.

The good battery apps like BBS are broken on KitKat.
But your battery life is not normal. Mine is quite good, about what I would expect. For reference, my GS3 would use 0.2-0.4% per hour while idling during the night. I can't get real numbers or monitor wakelocks on this phone yet. But so far, seems at least somewhat similar to that.
Use Greenify.

We can't really answer about your phone without knowing your usage habits. I mean, what you posted doesnt seem bad, especially if you're in a crappy signal area or play games.

A brief summary of my brief usage. I haven't played any games at all since I got the phone and the only usage has been social network apps and very light browsing of around <20 minutes. Oh and I made a call that lasted around 15 seconds. Everything else is stock setup. I have unlocked the bootloader but I did that prior to setting it up due to it wiping everything in the process.
Basically I've used it as much as I'd use my Nexus 4 and that wouldn't see so much as a 30% drain by now. The only thing that I am looking at as a possible cause is that the phone defaults to wanting 4G only. I'm not on a 4G plan or in a 4G area but even with that Mobile Standby is only showing 4% battery use. Suffice to say I switched that to 3G when I saw it just before posting. As I said, I'm going to drain it completely then charge to full and watch it very closely but I wanted to get thoughts while I waited.
I have contacted Google to see if there are any known issues that have popped up but the response I got just suggests turning off practically everything! Why would I opt for a powerful phone just to turn off sync, location services and anything that makes it a smartphone? The baffling one to me is suggesting I switch to AIRPLANE mode if I'm not near WiFi! I didn't buy a WiFi only tablet, I bought a phone!
"If you know you won’t be near a mobile or Wi-Fi network for a while, switch to Airplane mode"

I have been very pleasantly surprised with the battery life with my Nexus 5, I have noticed however that Google Location service likes to use battery power, more importantly - GPS - way too much..
However, I leave it on and even still it easily lasts me a day of use, with around 30-40% left depending on how much I use it.
What are your highest apps in the battery use screen?
Try turning off Google location services.

I am really pleased with battery life. Around 30-40 % left at end of day.

I saw similar with the Nexus 4 but refused to switch off location services and it seems ok. I've attached screenshots just taken. It seems I was a little off with my browsing estimate which shows 36 minutes in Chrome but still hardly astronomical.

OK so far the general opinion seems to be that it's just me. That helps me eliminate the phone and / or battery just being awful so thanks guys.

I'm at near 11 hours and am at 69%.. with an hour screen time. Not great but it easily gets me through the day. By the time I plug it in tonight it will probably have 20-30% and 3 maybe 4 hours of OST. That's more than enough for me
I should mention I have location off.. and only turn it on if I'm going to use the GPS
I also have Google Now off I don't need those flash cards to tell me how long it's going to take me to get home.. it's useful sometimes but I rarely look at em.
I'm pleased with my battery so far.. for the super heavy user they definitely wouldn't get a day.. but for me I'll get it easily.

its been pretty terrible for me with identical setups as other devices.
it has me seriously contemplating going back to my htc one. overall i do love the phone tho so hopefully I get a better idea when betterbatterystats is updated.
Few things with battery thats annoying me is google services kill this phone worse than any other ive owned. Even with google now disabled and location disabled. Also my daily drive to work I always use waze w/ screen on. With my other phones (htc one / n4 / iphone 5) i generally lose between 10-15% battery. On this phone im easily losing 25%.
I have access to charging so not a huge deal for now. Its a new os update so maybe it will get ironed out.

you are forgetting you are having a full HD and quad core phone now.

Ahh you got that google services bug eh.. that will kill any battery

Despite not wanting to I did a factory reset and installed a handful of apps, nothing that should cause issues anyway. When I got to Twitter though just after installing I noticed two warning notifications crop up that I remember just dismissing without thinking last time.
com.google.android.gsf.login
com.google.android.calendar
Both state they need installation of Google Play Services. I've ignored them for now so it'll be interesting to see if they have anything to do with it. I know the screen is going to be using more battery than I'm used to when it's on and notice that in battery use it's just everything else.
Friday will be the ultimate test of sorts. I've disabled WiFi, I'm charging it up and have disabled a few location things I don't care about. If it goes down hard again then it's going back.

I don't think what you're getting is that out of the ordinary. Between screen time and cell reception (the largest contributors to battery life) you could easily be seeing 'normal' battery life.
Don't expect more than 3.5 hrs of screen time, especially if you have reception issues when not on WIFI. And I'm talking 'normal' computer/dev/IT guy usage (e.g. using the phone as it's intended aka using google now, using one or two emails with push sync, using music services occasionally and sparingly during a day, NOT running in airplane mode, not disabling a crapload of smartphone features).

Evita Battery Life w/ Data Connection

So I've been tinkering with my phone for about 5 months now, searching forum after forum in hopes of getting some decent battery life out of my Evita. The best I'm ever able to get having mobile data and WiFi on throughout the day is about 9 hours. That's with light to moderate use (an hour of streaming music, 2-3 hours of screen time, only mail and calendar sync for Google, 0-20% screen brightness, no games, and being around WiFi for about 70% of the time). That benchmark was reached with CM 10.2, boosted kernel, sweep to wake enabled, and GPS on for about 1.5 hours. I can get about 16 hours if I disable all sync, underclock the kernel, disable all internet connections except when I use them (about 2 hours of the 16 on a normal day of checking email, reading news, syncing accounts and such. No heavy stuff such as streaming video etc.), and disabled GPS. However, I figure what's the point of having a smartphone with data connectivity if being connected means I can't even make it through a very light use work day? I've had my phone replaced once by AT&T because 8 hours was the best life I could get on stock period. That was with data and WiFi off (about 3 hours with internet on). I considered buying an external battery case to get a more normal battery life but can't justify dropping $100 bucks when that's what I paid for the phone with a contract in the first place.
Anyway, is this battery life normal? And if not, is there anything I can do to increase my battery life and maintain mobile data connectivity/WiFi? I would also love to be able to keep my GPS on as it's frustrating to wait 5 minutes for my GPS to find my location so I can find my way around. Whenever I need to use my maps. Anyway, it doesn't seem like this is a normal smartphone experience I'm having but I could be entirely wrong.
Thanks in advance.

The battery life you're experiencing looks fairly normal to me for the usage you describe. Sync kills battery, mobile data kills battery, GPS kills battery. All in all, HTC did put an underpowered battery in this device, which certainly doesn't help but there are steps you can take to combat this problem.
You say you want to leave the GPS on because you don't like waiting for it to connect, but if you do that the thing is going to try to connect constantly, even when indoors, which will drain your battery massively. My GPS connects in seconds, try using an app called Faster GPS.
Leaving mobile data switched on has the same result, why not switch it off when it isn't in use? You can use a quick settings tile to easily switch on and off as required and it will save a heap of battery.
Think about it like this, you don't leave the car running when it's in your garage, you don't leave all your lights on when you're not home, you don't keep the clothes dryer going when there are no clothes in it. Why? Because it's a waste to have all those things operating when not actually in use.
Use an app called Greenify to hibernate apps when they're not in use, you'd be surprised at how often apps run in the background when you're not even using them.
These are just some practices you can adopt to get better life our of your battery. I think people have pretty unrealistic expectations of how long a smartphone battery should last, considering all the things we ask to get out of them at the same time.

Hey Timaa, always appreciate your input. I'll try working in those ideas and see what battery life I get. Also, I believe I found a fix. I installed the 4.4.2 version of beanstalk and enabled the conservative governor and I'm pulling between 15 and 20 hours with Wi-Fi, mobile data, and GPS all enabled all day. The 13 hour cycle is on the moderate use side (2-3 hours of audio streaming, 4-5 hours of screen time, a couple games, internet browsing, Google Now enabled) and I have the pocket wake feature on. But an average day for me gets about 17 hours. More than enough to get me through my day. I've never even approached this kind of battery life with this device and I must say, I'm blown away! My battery now easily performs my old iPhone 4 which is really saying something. Couldn't be happier.
