So yes this Phone's battery unfortuanatly is not well at all.. but here is how i managed mine to last a day without charging. Let me also say im a heavy user also. I text A LOT and always pull out my phone in class play a few games to pass the time or just browse my phone. So this does work for heavy / light users.
Go to Wifi/ menu / advanced and click never on Keep wifi on during sleep.
Go to settings/ Location access - Switch to off
For your brightness it will be on Auto switch that off and put it almost to the lowest as you dont really need it high just kills the battery.
- Go to the App store and download Easy Battery savor. When you access the app choose intiligent mode. It really helps !
-Dont ever use live wallpaper it just drains it so fast.
- DOwnload Faux App It really helps (Faux kernel Enhancement Project) Once downloaded go to CPU and set max clock to 1.35 instead of 1.5. it will still be buttery smooth and it will drain the battery less.
Also I am using the Franco Kernel - nightly #53 which in my opinion really helps !
- Try to turn off the WiFi usage as much as possible and you will see a huge difference.
That's all from me guys. By doing all this my battery significantly improved and lasts about a day now.
Anyways if you have better solutionson how you manage your battery and how you extend its life.
- post pictures
- post the apps you use
- post everything !
Thank you !
I use harsh. Whenever I don't game, I lower the max freq to just 810mhz, ondemand, row, mpdecision on (as harsh recommended) and it's still buttery smooth, and of course battery life is incredible, and I also do check the Disable HW Overlays and Force GPU in 2d rendering. And since no kernel controlling apps are needed, my phone feels cleaner too I can't upload battery stats yet as I'm in an area with only edge connectiom and I hate using slow internet connections

A couple of things I noticed with this. The first thing I notice is, in two of your screenshots, you appear to have mobile data disabled completely. The second thing I noticed is that your final screenshot shows 24hr 52 min on battery, yet according to your clock, a it should really be a total of 33hr 6 min since unplugged. Your first screenshot shows 88% battery remaining with it already having been unplugged for 7hr 35 min. With that screenshot showing a time of 3:11pm, that would mean your phone was unplugged at 7:36am. If the phone was unplugged at 7:36am, then how is it only showing a total of 24hr 52min at 4:42pm the next day? It should be showing 33hr 6min. That's an odd inconsistency there. All in all, even with the data that is showed in your screenshot, it shows very little use as phone idle and cell standby are both in your top 5. Your screen was your highest drain, yet there isn't anything else there accompanying it. I could be wrong, but it seems to me that all you did was keep the data turned off on your phone, and connect to wifi where available. You turned your screen on, but didn't really do anything with the phone besides having the screen just on. That said, even stock with no changes, a person can get 24 hours on a charge if they're disabling their phone and not using it.
Interesting tips however I have a few points:
Your first tip suggests having WiFi to Never stay connected during sleep. I am part of another Android forum which deals with tablets. We tested this feature as with a tablet, you are likely to leave it for hours on end before using it again. It was excellent if the tablet was not touched, however we noticed that it significantly increased the battery drain if you were regularly switching between sleep and using it.
Agree with the second but don't throw away practicality, use Location settings when they need to be use, not just turn them off and don't use them.
Leave it on auto-brightness dude, why ruin the nice visuals of a fantastic screen by having it so dark you can't see it? I only ever use lowest brightness when its dark or the battery is nearly dead.
No idea about the battery saver.
I definitely disagree with this. If you use 3G permanently, like I do, then turning on WiFi definitely reduces battery drain. I don't turn off data ever, so switching WiFi where possible is quite a useful battery saving technique.

His solution is to turn off connectivity and functionality on the phone. That defeats the purpose of even having the phone at all.
That said, I think a safe UC of maybe 200MHz can have a difference, but to me, it's all about enjoying the phone and the phone experience. No need to screw with it
Don't do the wifi feature. It will use more battery because it will constantly have to reconnect to the wifi connection every time your phone comes out of sleep mode and that will consume more battery.

Just curious, why did you buy it then? Personally, I'm leaving everything on because I bought the phone for the looks and usability.
And yes, the phone lasts me all day while using it for everything including emails, conference calls, web browsing etc.
I've set up profiles using the Smart Profiles app to quickly turn things on and off at will - hit CAR and bluetooth/GPS turn on, Wifi turns off. Hit HOME and the reverse happens, etc.

Same thing here..but I use scripts When I'm in school and all I need my phone for is some tethering and music, I activate my script that sets the max freq to just 810mhz and I undervolt an extra -50mv from the stock undervoltages of harsh, but when I'm out and away, I enjoy the full 1.5ghz quadcore beast trapped inside my pocket

Don't get me wrong, it's useful to have a decent battery life, but I really don't see the need to turn the device into an expensive brick. My suggestions, which may or may not be better than the ones in the OP, but they seem to work for me on every Android I've come across without screwing with undervolting etc:
1. Turn Auto-Sync off, or increase the duration between each sync. On my old phone, the phone would use Auto-Sync every hour or so which totally killed the battery over the course of day. I turned it off and would sync it manually (taking all of 15 seconds) on a Friday. Made a huge difference, although simply increasing the time between syncs is just as effective if not more so as you still save a bit of time (might opt for that myself :good
2. Use Inverted Apps on SAMOLED, Don't use Inverted Apps on IPS, white colour uses more battery on SAMOLED, but a lot less on IPS :fingers-crossed:
3. Get yourself a Toggle-based Notification bar, you will remember to switch off your WiFi when walking around in public. To that end, switch your WiFi off unless you are connected to a hotspot, the constant scanning will drain your battery and depending on the interval may take quite a large hit over the course of a day. If you rely on WiFi then maybe increase the scan interval time.
4. Turn off all mobile networking services when in a known signal blackspot. e.g. When work pays for us to go to a hotel on the Welsh border in Cheshire, there is absolutely no signal guaranteed unless you go to the end of the driveway, so I turn off all phone services unless I am there. Your phone will drink your battery very quickly otherwise, guaranteed. The easy solution is to use WhatsApp, switch your phone onto Airplane mode then turn on WiFi and connect to a hotspot (if they have one available, hotels usually do). This is surprisingly low on battery consumption.
So basically, just leave my phone in my pocket and not use it. Okay. Gotcha.

My battery life is amazing. I guess it just depends on what you compare it to. I had an evo 3d before, and my 3d would be dead by noon without even turning on the screen. My work blackberry lasts 5 days with fairly heavy email usage.
My N4 though, I use it fairly often for browsing, occasional calls throughout the day, streaming audio, this and that. After 12 hours of use I am still at 60% usually. From 7am to 5:30 (typically when i get out of work) I will be at 70%+
Not sure why people are so bent out of shape about it...
On my 3d if I ran facebook app or any stupid **** like that it would kill my battery like i didnt even have one.
Here's another idea get a job or pay attention in school. That will save battery life as well. I have literally seen people stare at a screen without doing anything with the phone, just because they are so obsessed with it being in their hand

Hi everyone,
I brought this wonderful phone (or atleast i thought wonderful) couple of weeks ago ( delivered on release date)
Now i expected the battery to be good as its 2300 mah but it the phone doesnt seem to last no way near as long as other claim i had an s3 before this htc one, 9 times outta 10 i only had to charge it once a day and never activated power saver mode,
On the htc one i constantly have power saver turn on and it just doesnt seem to be doing anything , i havnt changed my usage of my phone, if anything ive used it less,
For example the s3 lasted my full 8 hour shift with nothing running expcept the tunein radio app, the htc one only seems to last 4-5 hours with everything closed except the tune in radio app. Ive not changed networks so low signal shouldnt be causing the drain as there isnt a difference in signal levels,
So is there anything else i can do to stop bettery draining. Bluetooth, wifi, nfc, etc all turned off, screen on auto brightness ,
Sent from my htc one with just 26% battery left and i havnt even rrached 4 hours of my shift yet, left house at 9:45 with 100%
You probably have an app preventing the phone from sleeping. There are loads of tutorials on how to check for partial wake locks to fix this.

Try this or this to detect the wakelocks. For more info on wakelock, read this thread
Definitely sounds like you have an app which is preventing the phone from sleeping and you should be getting a pretty easy 1 day out the battery at the very least in moderate use.

How have you TuneIn setup.
As general when you press pause rather than stop, itt continues to record that station and is always active. Iif you go into the app settings and turn off 'autostop recording' which should be defaulted to 8 hours - turn this to never and try again to see if it improves. I've seen TuneIn eat battery life on other devices where ths happens (people thinkits stopped when its just paused and recording away in the background...
That's possible ^^^^, however if he was just to hit exit on the app it should stop the services. That and really want to be sure, swype it away in the multitasking section.
Can try Betterbatterystats in the play store as a lot of people rave about that.
Also make sure Google Now is disabled. It sucks battery life like no other. Awesome tool, however to much drain on the battery.

Guaranteed that you have horrible wakelock issues. Rogue apps, bad settings, and anything in between could be the cause.
I can go to bed with the phone fully charged and, 8 hours later, wake it up to see it's still at 100% (mobile data, GPS, WiFi left active.)
Once I'm bored of constantly picking it up and playing with it (i.e. get back to standard usage patterns) I get the feeling it will likely run to 3 or more days between charges. Won't be this month though

Well there are various reasons for this..Maybe an app that drains much battery not leaving cpu to sleep.You can download better battery stats and see the wakelocks and the cpu states that your cpu runs on.. You may also need a battery calibration.It will not increase the battery capacity of course but it will eliminate the faulty battery stats bin that tells the system the battery percentage.You may have for example 25% battery left and your device may show 2% or even close.
I assume that you do not have wifi always on, screen on for hours or using mobile data..The consumption of battery is huge.

Worth dialling *#*#3424#*#* and doing the battery test, although as everyone else has said it's more than likely an app.
I had a sgs2 over 2 years,rooted and optimized in battery usage, i was already happy. Now with the htc one it's a completely new experience....already now after a few days,with root but still no tweaks i get 60% left at 11pm!before the sgs2 was empty...can't wait

Download Better Battery Stats, leave it for a day and then upload a screenshot of your wakelocks. My battery is easily lasting the day (ended at 11pm at 76% yesterday)
Same-ish problem.
Hey i'm having a similar problem,
I bought the HTC One (silver, 32Gb) A couple of days ago and the battery isn't even lasting a day with what I'd say as Medium/light usage. I do leave Mobile data on so i can get Skype/Facebook/line calls ect instantly, but i assumed that's normal.
I just left my phone alone for an hour with the screen off and it lost 4%, could this be a battery defect?
Are you telling me to get over a days usage, i have to leave mobile data turned off and only turn it on when i want to use Skype ect?
I saw a post above that one guys gets 3 days of usage with Mobile date, Wifi, etc all turned on. Is this the norm, or does he have a super hero battery?
I see the general consensus is to download "Better Battery Stats" and send pics of wakelocks, but Is there comparable app for free that will do the trick, as i don't have money currently on my English account.
Thanks to all those taking time out of their own lives to help others.

Thanks for the tip. I had motion deactivated to conserve battery but didn't like having to press the button each time to wake up the watch. 30% a day is not bad at all. I would even take 50%. Anything is better than the 24 hour time I've been seeing posted by reviewers. That worried me a bit. The good thing too is it charges fairly fast. So that 30% drain will be quick to recover.

Do you find that battery life on your connected phone suffers? I know keeping the BT radio on will have an impact, but I noticed I had to change some settings in JuiceDefender to allow the data connection to remain active so that S-Voice will work on the Gear. This, of course, means my phone's radio (data or wifi) is always on, when before I used to let JD turn it off while sleeping.
Haven't had the Gear long enough to tell whether or not this will have a serious impact but wondering if there are any tips? I tried finding a setting in JuiceDefender to only turn the radio on when the S-Voice is activated. Unfortunately, that doesn't work.
please help me.
after null_16 my battery life is short.
after 6 hour (only in watch mode without notify or other) my gear shut down.
could you give some tips for extend the battery life ?
thanks
If I turn off the motion wake feature my Gear will go three to four days easy but if I use motion it won't last longer than 12-14 hours. This is with moderate usage. I get probably a total of 30-40 emails and texts and other notifications a day and maybe 10 phone calls. (Most calls not answered on gear) maybe 3 a day. I would love to be able to use the watch without pushing the button. Even a tap on the screen to wake would be acceptable to me. The pebble uses a shake motion to wake which also is better than the Gear motion. I drive for a living and every turn of the steering wheel activates the screen. (Although battery life is not improved on days off.) if I side load apps will my battery life be severely shortened? And to the person who asked about the Bluetooth running all the time, it doesn't impact the battery life of my phone hardly at all.
I added a few awesome apps to my rooted s6 and i've saved about 70% on my battery life.
Greenify (will put apps into Hibernation when you turn off your phone so they don't run in background)
Smart Wifi Toggle (will turn off your wifi automatically when you leave a hotspot you've connected to before like work or home. Can also turn off wifi when your phone sleeps)
AutoBluetooth (will keep bluetooth off unless a call comes in, your currently connected to bluetooth device, or your in your car travelling for handsfree)
just these 3 apps seemed to have doubled my battery life. just wanted to fyi so people could check them out.
Thanks for the ideas!!

Though I might not be as harsh as you... I tend to agree. Greenify is basically like turning on the power saving option. Auto wifi might be good for convenience but it's not too bad to just turn it off when not in use. If I know I'll be away from a charger for a while I just turn on power saver and I'm golden.

Lags all over the place when scrolling, the play store is horrible when scrolling apps.
Right now my S6 has better standby on 4G and more life in use than my tablet has with no use!
Any ideas?
Can't speak for Lollipop, since staying with 4.4.2 and disabled auto updates. I only lose 2% in ten hours and the best Android tablet I have owned- especially in regards to low sleep bleed.
clearly something is not right have you factory reset it? That would be the first thing to make sure no apps are doing anything weird.
I flashed a whole new OS... should i wipe it?
You need to install a wake-lock checker, it will show how much time your tablet is actually in deep sleep mode, which uses the least amount of power, mine shows 97% time in deep sleep.
Some application can keep you tablet from going to sleep, alarm clock and sync can also, and apps/software you downloaded.
Do you get still get major battery drain after a reset, dont install any software/apps and the charge to 100% and then leve it for a few hours and then check how much power you have lost.
John.
Over an 8 hour period (avg) with wifi on, my screen brightness set to 10-20 range (that is the brightness I prefer on my tab s), and with greenify I lose maybe 1-2% battery. You definitely have some program or service constantly running or waking up your tablet, and due to the interactive governor that samsung uses your tablet wakes up at 1.9GHz each time to be more responsive/save battery by handling what ever is needed as fast as possible so it can sleep again. Unfortunatly if some app keeps going "hey, hey, I am here, I need you tablet, hey, hey, ect........." that battery saving governor will murder your battery.
So i wiped and its still 48 hour batter!
Battery %bleed
Losing around 30% battery over night idle.
*wifi & sync on...
-Ahmed-
Do you need to have your wifi and sync on for business or something, if not turn them off, of use an app to to mange them like the free juice defender ect.
Just install it, make sure it is enabled and then make sure the icon is on your taskbar so it has not been killed, and them forget about it for a week and see how it goes.

for some reason on this tablet, wifi murders battery in standby. if you turn it off it lasts much better... but this tablet and this tablet only, leaving wifi on kills it horribly. but problem is, when you wake it for teh first time in hours and wifi activates, all of a sudden everything syncs and it's so damn laggy those first few minutes of use. it sucks. only this tablet. never had this issue with my nexus 7. that thing gave me 7 days stand-by time.

Try putting your tablet in airplane more overnight and see how much power it consumes. I lose 3% over 8 hours when I put it on airplane mode and disable wifi.
Im sorry but this is BS.
Its clearly faulty. its going to samsung. i demand a refund.
How much power wifi uses depends on the distance to the router and how much interference it has to try and break though to get a good connection which means using more power, that is why wifi uses more battery power on some peoples tablets than others do.

disregard.. just realized my screen shots were messed up. I'll post my standby time tomorrow.
Here is a very simple stock no root mini guide to getting 1-5% loss over an 8-10 hour period while sleeping or at least while the tablet is asleep.
1. Install greenify even if you are not rooted and even if you do that have the donor package there are many many apps that do not like to sleep, greenify will fix that for you.
2. Unless you are a Doctor, CEO, or someone whose very life hangs on getting the latest cute cat post while you are asleep try to adjust your sync times from under an hour to as high as you can. (If you are turning off wifi then it might still matter if the app wakes up your device just to see it can't sync)
3. Samsung has given you a very nice QHD screen. It is high resolution, Amoled, and other nice rhings but while you sleep you can not see it so turn the brightness down before you touch the power button to 5-15. If you wake up in a dark room and need to use your tablet that level of brightness is far kinder to your eyes and even kinder to your battery.
Just doing this generally kept my battery usage down to only 2-4% per night, of course then I rooted my tablet and installed TW detox 3.0 and now it is closer to 1-2% per night. Try any or all of these and I hope it works out.

losing 48% per day... screen brightness wont help will it when screen is off all day
Screen brightness is for those times that an app wakes up the tablet and turns on the screen to tell you something (new email, facebook wall post, new cat video, ect....) and yes it helps.
If you are losing 48% a day then you have some app doing something that is keeping your tablet awake for a good portion of the day. Or you have a defective battery/tablet. I can surf the web for a good portion of the day and maybe lose 48%.

Are you rooted. It's sounds like you have some wakelocks? If rooted you should use greenify and a wakelock alarm to fix the problem.
i'm curious to see what apps and how many you have installed. Can you post screen shots of your app drawer?

what email apps and cat video watching apps are you using that turn the screen on? no app that I have EVER turns my screen on at all. the only app that does that is on my phone, and it's from textra, an sms app that isn't on my tablet.
