[Q] short battery life s4

I takes about 10 hours, the lesson download much battery? when I go to sleep I lose almost 15% of battery. Any solution?: (

Battery life is terrible.
I refuse to do what my friend does:
Turn vibrate off
Turn screen brightness to lowest
Phone is always connected to Edge - unless he's using the Internet - then he switches back to Edge
Syncs his email every 15 minutes (pull not push!!!)
Always 'freeing ram' and exiting apps
His life sucks.
I am the opposite. Full brightness, 4g , push mail for my 4 emails, exchange server (email and calendar) for work and so on.
I manage this by always having a spare battery that I charge with my battery charger dock lol.
Will be doing the same thing once I can get one for my S4

I know, so far it's been below expectations for me too - I ordered a portable energy bank from Amazon this morning, and I guess I'll just carry it around with me from now on.. What a shame - the phone is extremely powerful too..

Install gsam battery monitor and let it monitor your phone and see what is causing wake locks. Also let the battery go through 3-4 battery cycles before you start comparing battery life.

That'd weird. Isn't the 9500 or the 9505?
My battery exceeds my expectations by quite a lot. Best battery I've had on a smartphone so far, and I've had a few.
Where my 920 died, this one still has 50-70% remaning.
Thats with push mail, air view, air gestures, wifi, mobile data, auto brightness, screen rotation, sync, gps and multiwindow on constantly.

Seriously? how much is the battery life? can post some pics?

I am also curous how many hours does it take for the battery to reach 15% and how much screen on time do you get. Please post a few screenshots!

After a day i have like 30% left. Screen on time is about 2h.

battery life is not a issue here I don't think I can get to 15% easily most day I do not but I will try to get some pics posted after an all day use no promises I manage to be busy a lot lol.

I am constantly using it.

I'm trying it right now. It takes a bit more than two days for the app to learn certain usage patterns. I still have to wait 8 hours until the actual battery savings start. Will report as soon as I have it working.

I get similar battery life as well. Sometimes 4 ton6 hours screen times
16 hour days
I found my battery life improved when I got rid of a poor quality 32gig media card and used another spare old16gig one.
I also dumped corrupted mp3 files and videos and got new ones.
I think poor sd card quality and bad mp3 files are partially responsible for lower battery life.

just got mine
first charge cycle
4 hours on screen
total 8 hours
15% left
not very good but i think it will get better

So far with battery saving on it seems that nothing changed... Will test it further with daily use. But battery life here, even before using the app was not bad by any means.

S4 Charges fast and Discharges fast

Hello,
My S4 is nearly a week old now, it's the international GT-I9500 octa-core version. Since it dons a big battery of 2,600 mAH (middle point of S3 and Note 2) it was suppose to last long more even with heavy usage.
My usage is moderate, a few calls, but I use connectivity extensively i.e. WiFi indoors and Mobile Data outdoors.
I tried switching off the WiFi to preserve battery and to see any boost but zilch.
Whenever I put the phone on charge, it charges very quickly and when the charging is complete and I remove the phone from the charger, it discharges pretty quickly, goes to 99% in a minute WITHOUT any usage.
What could be the issue? I even formatted my memory card from S4 as I read some bad mp3 files or something can cause the battery drain and such.
Everything is stock, both ROM and Kernel and the phone is not rooted atm
I'm attaching the screenshots for my cycle with minimal WiFi and Data usage.

I can get more than 16hours on my S2 easily with average usage...This is just BS optimization from Samsung...

It's better than the s3 because the battery is larger but I'm telling you that screen is a hog. It's larger and brighter and its 1080p; yes the resolution causes the gpu to eat more battery too.

I freaking hate watching my battery drop.. and mine goes by quite quick. . I have wifi and mobile data on.. When I leave my house I toggle off wifi. I read that having mobile data on all the time doesn't use battery. . Is that true?
Anyway. .I just turn off the battery percent.. Can't stand putting the phone to sleep at 80 and turning it back on 20 min later at 75.

im wondering if there's a way to switch the screen to 720 mode instead of 1080p to save battery life. similar to switching a computer monitor so you stress the gpu less during a game... this would also save a small percentage of battery life...
also a more efficient auto-brightness would be great.

Same here, hate watching the battery drop so soon. For me, what I've observed is that WiFi eats a lot of battery than mobile DATA for this set when it should be the other way around...
I have my internet disconnected at home due to some upgrading of the lines in my area so I haven't been using WiFi at home, only at office, so mobile DATA was switched on all day yesterday at home and when I go outside and surprisingly the battery didn't drain a lot.
I'll post screenshots of this cycle as soon as the battery drains down to 2%

No! Mobile data is one of the biggest battery killers going! I have my toggle within the first 5 so I can turn it on and off when I need it easily
Sent from my GT-I9505 using xda premium

With big screen and higher resolution, it will definitely consume more power. try to turn off screen and kill running apps when not needed.

16hours on battery is quite good considering the WIFI indoor and Data on.
i probably get a little bit more than that but less wifi usage and data is only EDGE in my country.

Nothing alarming
Firstly, your stats are perfectly normal. I got the same results on my stock octa core version.
Try omega its much better battery consumption wise. Other tips: Switch to 2g only if you are using your phone just for chatting, keep backups off and turn unnecessary sync off. Turn off your screen tap sounds.
You might already know all this.
Anyhow, trust me 16hours at 60% is not bad. Hopefully samsung will do something about it with future updates.
CHEERS.
Ow and if you are over with your honeymoon with all the air motion gestures smart eye tracking features, turn them off if you want to save some more.

HTC One 4.2.2 Update UK

I just updated my HTC One yesterday and the battery drain is ridiculous. I took my phone off the charger at 6am today and watched some of a film listened to a bit of music and sent texts as usual and phone went dead at 2pm !
Usually it would last till 6pm with heavy usage but since the update the battery life has deteriorated.
My phone is less than a week old and overall really impressed with it till now.
Anyone else having this issue and can suggest a fix?

You may need to give it a few days and a couple of battery cycles to settle itself down again. Try installing Greenify to 'hibernate' running services in the background and BetterBatteryStats to monitor kernel wakelocks and what's using your battery in general..

Agreed. Just downloaded green power premium from play store and juice defender ulitimate lets see if they can help. I like to have auto brightness a d to use my phone so this update is bugging me (((
Sent from my HTC One using xda premium

For me the 4.2.2 update has improved my battery life.
Everything completely stock, get about 35-40 hours battery life (100% to ~1%) with 2 to 4 hours on screen time. Obviously depending on what you do with that screen on, will dictate just how much battery life you use. But for me, usually browsing, reading, watching YouTube. Dont really game or do anything massively intensive.
Also everything on stock normal, (locations, gps, auto sync, blinkfeed, etc).
As I said depending on what you do with your phone, your battery life with on screen time will increase/decrease. Also whether you use it as a smartphone (all sync etc on) or reduce it to a phone (2g, power saver, screen dimmed, etc) makes a huge difference.

I'm working in dark rooms so why keeping display brightness not at minimum? And on most places I only got 2G network, so why not forcing the phone to only use this?
And sync... Yeah... I don't need the weather to be updated every hour... Or news... They're appearing on my BlinkFeed anyways...
And I'm using my phone as a smartphone as well Over 6 hours screen on time is mostly Facebook, WhatsApp and browsing.

Why can't android manage battery like windows does or even better htc work with Google and sort the issue.

100% agree with you..now the phone charges quicker but it discharges quicker too.. yes i did hard reset, autosync etc etc.. no change of my usage patterns, i now get half the usage..
dont know why htc just didnt go straight to 4.3 as this significantly improves battery life..4.2 acrosss the board was a bad update.

Anyone tried the Snapdragon™ BatteryGuru app?

___ BATTERY LIFE THREAD ___ Being raped by Android OS!

Who is having issues with battery here? Android OS is killing my juice! I have gotten fed up and rooted my sheild and frozen most everything possible to try and get the OS down. I will lose like 30-40% overnight. I was thinking it was the shield or nvidia services tied into the android OS but that doesn't seem to be it. Blake_wavelock seems to have a lot of the activity and deep sleep isn't Happing as it should. I haven't tried WiFi off when screen is off and I'm going to use that tonight. I have all the location setting and Google setting inactive. I'm using optimized for battery.
Let me know what you think. I come from a posse of Samsung devices and get great battery life on them.(of course they are all rooted and ROM)

Have you checked under WiFi advanced settings for keeping WiFi off while screen off and WiFi optimization? (Sorry if these settings aren't there, looking at settings on my phone, as I don't have this tablet, but I am considering purchasing one).
Also, is your WiFi signal poor or strong? Because that plays a big role.

I have this happening with airplane mode on. Only seems to happen when I'm home though.
Weird.

Those with bad battery life should check what apps they have installed and use wakelock to find out what's keeping your tab awake over night. I have had many android devices and unusual battery life like many of you report is virtually always due to a user installed app or combo of apps. I get 3 days use on one charge MINIMUM. This is with WiFi on 24/7, and I use it for homework for several hours a day and some light gaming thru console mode (maybe an hour a day). I use a custom power mode with 50% cpu clock, 2 cores and 30 fps. I never take it off this power mode cuz I never see any difference in performance. Il post pics from next cycle.

Yea I'm not seeing bad standby either, battery overall isn't great but OK. I get about 5 hours screen on but most of my usage is android games.

I guess all the hard work of freezing off apps has paid off. This is the type of sleep I'm use to!

75% left with only 10m screen on? That's not good...

That's more like it, still not what I call good but for something that offers everything I guess it's OK. Still wish I had a way of reaching 10 h screen on.

Twice now, I have gone from 70-80% to dead in just a few hours with the screen off. I have a few background apps with push notification (facebook, appy geek, mighty text) but they are all the same apps as on my oneplus one, and it only drains 1-2% per hour. Same with my Xperia Z Ultra (which I had set up as a tablet, no sim installed)

Go very dim and freeze everything and im sure you could get close! I do use greenify. I like app opps but to lazy to set it up.

I have the tegra note 7 and this shield. I pretty much just got both about a month ago. I have figured out that the WiFi hardware is not as good as most phones. So it will cause a wavelock and drain the device (which is labeled under android OS). So make sure under settings<wifi<advanced you choose WiFi off when screen is off or only when plugged and not to search for WiFi networks if you don't need. I have also seen that if you root then you can use titanium backup or whatever you like to freeze all the apps that cause harm or excessive battery drain. Also, with root you can use app called wavelock detector to figure out what app is draining you down. I have just about everything frozen except for updates and a couple other services. Good luck report back on what's causing it if you can. Blakewavelock got me, lol.
Here is this cycle from yesterday (still going) What wavelock detector looks like

Many people on various phones had this problem I am not sure how to avoid this, its not happening on every phone for sure.

Check your battery stats, that could easily be that you were in an area with low signal, which causes the phone to struggle to find service; thus wasting battery

I only know a temporary fix which is to turn on airplane mode then you can turn on wifi at the same time just thought it may help you figure out a more longterm solution.

It's a known bug with lollipop. It apparently has been fixed in Marshmallow. Wait for the update. There's not much you can do til then except stay on WiFi.

Thanks did and we will see when it gets charged to 100% its weird I think this also happens on WiFi but I can't tell for sure..
Sent from my XT1575 using Tapatalk

My phone does the same thing but when I go to battery stats and check it my cell signal bar isn't green at all. Orange and yellow is all I get because I get weak signal in my house. I never get time without signal in my battery stats tho.
I had a nexus 6 before this phone and it was the same thing except I would get 12-20% time without signal and it really killed my battery.
I haven't had a single day with this phone where I didn't get at least 4 hours of screen on time. The best I have gotten was 6 hours on wifi

The thing that works best for me is when I have WiFi on, I turn mobile data off. That works wonders and elongating my battery life at home. When custom ROMs begin to pop up, I believe CM patched the issue but we will see. But when you're home on WiFi, turn data off unless you need it and see how that works

MobileActiveRadioFix module in Xposed Framework is supposed to fix it (although I just deactivated it because it seemed to have made it worse for me).
I played around in my network settings this morning, searched for networks, and selected Verizon (previously I just let it activate on its own) and that seems to have helped my battery so far.

So far I'm at 55% with 1 hour 45 mins SOT. Yesterday I had to charge my phone twice. I was getting less than 2 hours SOT on a full battery.
Sent from my XT1575 using Tapatalk

So far today, with just WiFi on and keeping data off, I'm at 54% with just over 2.5 hours screen on. Cell standby is at 7% but my time without a signal is 1%. And may I ask what you did to select a certain network, @joshw0000?

Which network you on ? just put it in global mode and search for networks and select your carrier/unless you have domestic roaming then you can select other carrier to roam on. When I was in Europe and my prepaid carrier had roaming on all carriers that is how I would switch manually between carriers.

Something ain't right if your getting that low of screen on time. I just charged my phone today was off the charger for 24 hours and I had 5.5 hours of screen on time on WiFi and I don't ever have green in my signal stats its always orange and yellow.
I always keep my data, Bluetooth, GPS, NFC, moto display tweaks off at home and in getting great battery life. I've only charged this phone 6 times in 8 days because I wait til it's really low to charge and the quick charger has it full within a hour anyways
