[Q] Battery Life Issue - Samsung Epic 4G Touch

I am having battery drainage due to the display (unlike most people who are having battery issues because of the android system). I've tried dimming down the brightness and putting the screen timeout to the lowest possible but the display still sucks up most of my battery. Can anyone help me with this ?

I think that would be normal. It's a 4.5 inch touch screen; it takes a lot of juice to be so pretty ...
Under settings - about phone - battery usage - display, what is the time on vs. % of battery usage?
I've been off the charger for 30 minutes and display use is at 76% since I've been browsing news and xda non stop.
If your screen on time is low compared to it's battery usage, it's a different story. Sounds like you've tried the usual fixes.

Well I've been off the charger since 12 last night so it would be 12 hours. But the thing is that the display usage says 51% and the actual time on for display was only 2 hours.
and also my battery drains 1% about every 30 minutes with the screen off.

2 hours of screen on time sucking 51% of the battery sounds normal to me, even across other Android phones on GB. Touch screens use lots of power.
Maybe someone else can chime in with something I'm not getting, but it seems normal to me.

This is a screenshot of my E4GT after 33 hours off the charger with normal usage. I don't play games, but I do text a lot and had a few calls as well. As you can see, the screen was on 20% of the 33 hours, meaning 6.6 hours etc etc and I still had 9% battery life at that point.
I am loving my phone!

Doesn't that 20% mean that the display used 20% of the battery power, not that it was on for 20% of the time? If you select the Display, it actually shows you how long it's been on.

I just feel like my battery should last longer than it does. I used to own the moment and that would last me three days with moderate use. ButI guess that this phone is more powerful it would make sense not to last three days. If only that would happen haha

[Q] Is this normal?

Hello everyone
I got my DHD last week on tuesday, very happy with it so far!
So I was playing Slice It for about an hour and a half, and my battery went from 100% to 56%.
Battery Use shows this:
1h 36m since unplugged
Display 58%
Slice It 29%
akmd 5%
Android System 4%
Cell Standby 2%
Mediaserver 2%
Wi-Fi was off the whole time, brightness was at about 15-20%, and the volume at about 35%...
Is this normal for the battery to run out so quickly?
P.S. I did charge the battery for 8 hours before any use like the manual said.
Cheers
Yeah its normal for a less than 2 week old battery. My battery got progressively better every week up until week 5 or so.
Your battery will get better. Plus you were using your phone quite heavily so everything sounds about normal.
The battery doesn't last too long on the DHD. I've noted marked improvements by using a combination of JuiceDefender and AdvancedTaskKiller minimising bg apps.

battary life drains so bad(version1.28)

I charged my HTC ONE X to 100%, took it out of the charger and I have now been 1h 37m 46s on battery, and it ALREADY has drained to 70% !!!
what my phone uses or so it says :
screen 78%
cell standby 6%
android OS 5%
android system 4%
phone idle 4%
whatsapp 3%
what does it mean 78% screen? that my screen is the big killer for my drain? because that would make non sense since I have not had it on that much..and still.....30% in 1.3hours? that's just insanely bad!
stock rom from Holland btw...didn't change a single thing to my phone since I do not know how....
any input on why it drains so rapidly?
thanks!
I would post a screenshot but I don't have ''root'' access'' or something lol sorry!

firstly you can take a screenshot by pressing power button and home button at
the same time..
how old is the phone?
you are ok bro. for me it drained 17% with 15 minutes screen on time.
this is one big lol.
i am struggling to get 7 hours battery life
If you don't mind the effects on warranty, there are some system mods things that can be done to improve battery life...
Otherwise try turning off extra wireless services, and lowering the brightness on your screen.
I was getting 8-9 hours outa my battery, since rooted and flashed leedroid's rom and I got 26 hours with 30% to go....
what a difference.....
Basically in android, especially LCD screens, you can expect under 3 hours of continual screen use in daily activities. Often way under.
I've gone through a Motorola Milestone, Samsung Galaxy S and Nexus S, HTC Sensation and now One X. None of them broke the three hour mark for screen on time.
Standby and other use, sure, you can push a day or so but the screen is the major killer. Even with 1900mAh after-market batteries for the Sensation I was just about pushing 2.x hours. Screen usually on auto, but often inside buildings.
Counter to what may seem obvious is that if you have WiFi available - use it. It uses less power than the data connection on cellular networks and can improve standby time by a fair bit. Assuming you use push notifications and the like.

is rooting hard? i searched it on the internet but the only thing i found was some half-assed english site trying to explain what to do...couldn't follow it, and also it didn't work :/
I don't know all the terms etc they use so that makes it quite a fair bit harder for me!
Two Questions:
- What are your Brightness settings?
(Settings - Display & gestures - Brightness)
- Do you have Wifi/3G constantly on?
(Settings - Wireless & networks: is Wi-Fi and/or Mobile network: ON?)
How to improve Battery drain:
- Go to: Settings - Display & gestures - Brightness:
and untick: Automatic brightness
with your finger slide the brightness level to much lower than it is now (I have it at only 1/4)
confirm with: OK
- Whenever you do not need to be online (internet), make sure to switch off Wi-Fi and Mobile network
- Switch off notifications for e.g. Facebook, Twitter, Email (you need to open each app and in the Menu have to untick notifications)
From personal experience, I can tell you that having internet on constantly aka WhatsApp sending notifications for each chat message, Facebook and Email sending notifications, ... costs you a lot of battery
Brightness at full level also drains battery badly.
- Following above-mentioned tips, you will get a standby time on the HTC One X of up to 2 full days.
Hope I could help a bit.

You need to get on leedroid Currently on 71% battery also, but slight difference in how i got there:
16hrs standby
half hour screen on (auto brightness)
5 mins calls,
3g/wifi/locations always on.
Very light usage day for me, but it's very different results to yours
M.
edited for clarity/typos
who would you have your phone on standby for 16hours....I used it more than half an hour a day (half hour screen on as you said) so that says nothing for me lol
and my screen has low brightness but that doesn't really seem to effect it THAT much, but yesn i do have 3d on constantly aswel as fb whatsapp etc...but I do need to be in contact with people so I guess there nothing to fix :/ except maybe a ligh rom but i have no idea how that works haha, might search youtube
I have the same problem but i'm actually using the phone.
As a heavy user (and i mean heavy user) i've yet to get more than 3 hours on screen time with this. once i used it for only 2hours 20 mins and the battery was dead. I'm rooted running leedroid and the battery life is very bad for onscreen time.
Anyone else getting these figures.
hi guys..
i am on stock rom updated to latest but having problems with my battery
take a look at the screenshot. i currently have 30% battery.
as you can see from almost 11 hours of my latest charge 9hours and 20 mins
my phone was at deep sleep.(only 1hour and 40 mins of light usage)
when its locked it shows excelent battery (1% per hour) but after an hour passes and even if i just unlock it and browse a bit my phone ,i lose 5-6% .
my phone is 4days old only.
maybe the problem is just temporary?
thnx in advance for any help.
I'm using an App called 'Screen Adjuster', in which you can set the screen brightness (say 50%), and then auto adjust brightness within the selected range (50% range).
You can adjust the brightness anytime, I found it is very handy because the original auto brightness is simply too bright.
One drawback is that you can click to install 3rd party apk with this App running, don't know why, but just for your reference.
This is what i get.
With surfing a little bit gaming and chatting.

Few Questions before choosing this phone

Hope you don't mind...
Coming from a Samsung Galaxy s2
Thing i hated about the S2 was not so much the battery drain but the terribly slow charging time, Sorry to mention a fruit phone, but my wifes IP4 would charge almost twice as fast than my S2.
How quick does the ONE X charge?
Does the battery last 7-8 hours with normal usage (tricky to tell, as it depends on what normal I guess)
Does it get really hot?, as the SGS2 did with some games, almost to the point of having to put it down it was so hot
thanks John
Battery Monitor tells.me that the average
0% to 100% time is 4hr 49mins, though it will probably be a little bit quicker than that if you don't count all the times I've been playing with it while charging.
It does seem to take a long time to charge, and you have to remember that the battery is 25% bigger than on the ip4 (1800mAh vs 1420mAh ) so it will probably take 25% longer ish.
It does get warm when charging and gaming simultaneously but not so that you have to put it down.
And battery life is excellent when the screen is mainly off which is my use case. I stream music most if the day and its fine for me, but as soon as you start using the screen it does start to tumble.
Hope that helps. I really love the phone, and the screen is just immense.

i always thought if you use a charger with more amps, the phone will charge faster. i use an 2 amps usb charger and from 20% to 80% it charged within half hour last night, but the phone was off.
the question is, do you prefer touchwiz or htc sense ? i dont like both of them, so i still wait for a great none sense rom.
About charging...
Wall charger, 1Ah output
- 3.5-4 hrs, with the screen off
- add 30% time if you are watching a movie;
- add 45% if using the phone for browsing over 3G or WiFi;
- prepare for slow discharge if playing demanding 3D games;
USB computer output
- 5 to 7 hrs (the less you fiddle with it, the faster it will charge)
About daily usage:
Give or take 10% of these times, of course - based on personal experience
22-24 hrs total time of wich
- 2.5 screen time used for browsing via 3G or WiFi;
- 30 to 50' of talking
- autobrightness always ON,
- autosync off;
You can get over 3.5 hrs of screen time and some 1 hrs of talk time within a span of 15 hrs.
Gaming will bring MASSIVE battery drain, especially 3D games;
Of course, signal strengh is also important when talking or browsing. If you have autobrightness on during the day, in well lit areas it will obviously eat a LOT of battery as opposed to manual low brightness;
These average times I got on both Leedroid 6.1.0 and InsertCoin 6... ROMs using the stock kernel provided. Been testing them for about two weeks.

The issue with the battery is that is a Li-Po (Lithium-Polymer-Akkumulator) Battery and for this there is no quick-charge. The charge it´s a bit longer that with a Li-On Battery but the duration is great.
I usually charge it overnight using computer USB, and it will be fully charged in the morning.
If I charge it using charger, it takes about 3-4 hours (1A output).
Battery drains depends on how you use.
Screen drain most battery, internet and games also drain battery.
I used to switch off auto brightness, and turn brightness to 0%, then use Screen Adjuster to auto adjust within that 0%
The average temperature is around 35-40 degree after using it for a while indoor.
If you use it outdoor, it will get hotting up faster.
If it is under sunlight (e.g. taking photo), it is easy to go over 45 degree or even 50!!
It takes 200 minutes (or 3 hours and 20 minutes) to charge my HOX from 0% to 100%. As for getting hot; mine sometimes does but never to the point of having to put it down. Just hotter than it usually is, but nothing unusual really.

Bought new Z play/kind of disappointed with the battery life

Hello all,
I bought a new Z play to replace my ageing phone, and I have mixed feelings about the battery life. The phone has received universal praise for its battery life, and while some of it is true in my case, I can't seem to get those high SoT numbers that everyone brags about.
It's very difficult for me to break the 6h SoT barrier, and I consider myself a light user: whatsapp, browsing, some reddit, and the occasional music (through headphones). I don't play any games, or perform heavy tasks. Also the phone is connected to WiFi 85% of the time, get decent signal, and the screen is set on auto-brightness.
Running latest version of the stock rom, and I performed factory reset + wiped cache + reset network settings countless times as per suggestions.
Attached some stats for 50% that I just took.
Is there something I'm missing?
Take it with a grain of salt, just because people brag about numbers does not mean they are real or obtainable by everyone. Battery life will vary for every user and phone. The time you have is in the acceptable range and I would not worry.
Yes, even I have never achieved the 8-9+ hrs of SOT that's I've seen in some threads. Based on my usage I get a minimum of 6.5hr SOT with the phone lasting a good 25-27 hours before I have to plug it back in.
Since the phone is new it might take a few cycles for the battery to truly show its stamina.
Those answer are definitely right. It all varies on the users. . Also please makes sure you have bluetooth and wifi scanning off. (Location> Scanning > Bluetooth & Wifi Scanning) Another factor is apps. Get rid of facebook and facebook messenger. Apps that use GCM eat battery like a range rover eats gas. I've hit 8--10 hr of SOT before. Let your phone get use to your daily activities. I believe it'll optimize itself over time.
It's normal.
I was also getting earlier 5-6 hrs SOT(When the device was new) but not I'm getting 8-9 hrs SOT.
So as your phone is new it might take few cycles for the battery to show its full stamina!
Cheers!!
Thanks for the replies and for putting my mind at ease.
Bluetooth and wifi scanning are off (forgot to mention that).
Anyway, I understand. Those insane SoT of 10+ are best case scenarios with careful use of the device. Still happy with my current capacity (anything which lasts until the next morning is great).
And yep, the phone manual (who reads those anymore), did mention the battery taking a few cycles before reaching its capacity.
Now, for a different issue. If I'd like to disable turbocharging/quickcharging my phone, would a USB C to A cable coupled with any charger (including the quickcharging ones) do the trick? Based on my understanding, the cable limits the chargining power, so any regular (quality) C to A cable should restore normal charging speeds even when using a fast charging charger. In case you're wondering why I'd like to do that, it's because the phone gets way too hot for my liking when using the Moto turbocharger and I'd like to reserve that for when necessary.
Well, guyz do have a point.
The screenshots are showing you have almost 3hrs SoT after day and a half. This is normal.
Those >10 hrs of SoT aren't achieved with careful usage. Coming from my experience, I got 10.5 hrs SoT with 10% battery left, BUT, in one day. My Moto can last up to 3 day with one charge, but in those 3 days I'll have maybe 4hrs SoT. So, in average, my Moto lasts up to 2 days with 6/7hrs SoT (I mostly use FB, Messenger, WhatsApp, Viber, YT, Instagram, stock 6.0.1). It simply depends how you use it. That big, almost 11hrs SoT, I could only achieve on weekends, coz otherwise I don't have the time to stare in my phone so much.
On that other thing, Moto does get pretty hot while charging. And you're right, the cable does limit the charging power so it will probably work.
I was one of those users getting 10h SoT early on. But I was doing that inside a 24h usage window. Your 50% stats have you stretched out to like almost 3 days off charger. Idle time vs. screen on time is ALWAYS a trade-off.
I look at battery drain in terms of drain rate at idle, and drain rate with screen on. Early on I was seeing 6% drain per hour of screen on, and 1-1.5% per hour screen off. So basically 5 hours of idle time costs you 1 hour screen on. Those were my numbers on the original MM build. My battery life has gotten worse with every software update. I have NOT done a factory reset, mostly because I don't want the hassle and I still get a day off normal use with plenty of battery to spare. But I usually see 18h off charger and 3-4h SoT in a normal day, and that leaves me at 40-50% when I plug in.
Looking at your stats, if screen on costs you 6% per hour, you have 17% worth of screen on drain. That leaves 33% idle drain over 38 hours, or sightly less than 1% per hour idle. Seems pretty darn good to me.
Your cell signal is definitely not helping your battery life. Switch to 2g when on wifi, your signal bar should be full and it'll probably help your battery life.
Enjoy the fact that this phone lets you keep BT/WiFi scanning/Facebook/etc. on without having to worry whether or not you're going to make it a full day. I use all that stuff, have multiple live widgets updating, brightness at least half way, T-Mobile Digits running, and still make it a full day. Additionally, it's great to know that if you do have to make it 2-3 days with minimal usage because you don't have a charger handy, you can. However, I'm willing to bet that 99% of users are able to charge their phone daily. To those users, I say enjoy all the features and don't worry about it.
Really depends on the screen brightness...I can hit those number with my screen brightness turned down a good bit...probably around 30 percent and auto sync off...if i have brightness anywhere above 60 percent then battery life drops a good amount...still well enough to get me through a 12 hour work day but there is a difference

Standby drain

When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Sony Xperia XZ Premium's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
damn no reviews for this lol im just here letting you guys know that the standby battery is amazing went to sleep yesterday at 12am with 69% of battery woke up today at 7:30am with 67% damn my old lg v20 couldnt do that lol
It's quite bad here with standby drain as well. "Phone Idle" is always on top of the battery usage apps and it's probably a few percent an hour, depending on charge of course. >90% it's 1-2% an hour, but that increases when the charge level drops.
Stock .145 rom with storm//'s hack and have greenify running
Standby drain 0,2-0,4 %/h. locked BL, .145, Greenify.
phone idle coming top 3 with 6% took from 100% in about 4 hours! what could be causing that??
phone idle 4:11 hours
screen time 1:50 hours
36minutes of sniper 3d
7minutes playtube player while screen on (plus 20 minutes screen off)
I am on 57% just after 4 hours of use! while only 1:50 hours of them screen on!
phone idle for 4:11 hours took 6% which is a ratio of (1.5% per hour)
not good at all, what could be the problem??
I tried draining to 0 then charge to 100 on a straight charge while phone is off, phone is factory resetted, locked, not rooted, stock rom .119 oreo
what else can I do here?

I don't know but I have the same issue for months... Usually 2,4-2,8% per hour (when screen off!!) and battery stats not showing anything relevant.
I have everything stock, and I am using Greenify since a ~week, now I have 1,5%-1,8% on standby (which is still a lot, but improved compared to the previous situation).
Is really bad because if I detach my phone at 7 in the morning, at 14 I am already at ~80% without doing nothing! That's also means that using it, specially a lot with maps or things like that, I am not able to go farest than 17-21 :crying:

i noticed that factory reset didnt work for me, neither does software repair
so what I did was, flashed .179 firmware, fresh flashing, wiped every thing!
battery life was almost still the same, it got a lil better.
BUT, I am now using stamina mode any time I dont use the phone much, in my pocket, or even if im slightly using it (whatsapp, instagram etc...), I only turn it off when im gaming or watching some thing which is getting me to lose 1% every 4-6 minutes when using the device, and not losing anything when the device is off (as I activate the stamina mode) this should get me around 6:30-8:00 hours of screen time!
also I noticed I had viberation on navigation buttons, I also had face detection unlock and "ok google" unlock, and google feed and a lot of widgets and a live wallpaper, and avg running in the background.
so I disabled all of these useless features as I really dont use any of them (maybe rarely) and i can feel a slight improvement. (still slight improvement over slight improvement makes a noticeably improvement)
so now I unplugged my device at 17:00 at 90% more or less and now its 22:07 and i still got 56% so in about 5 hours I lost 34% while 2:14 hours, screen was on so its very impressive!
I can get to 6:45 hours of screen use which is very very good! im still testing though.
Nah i know its too late to write this but,.
For you all who have a problem draining battery even at sleep try Greenify Donation Package + Powernap xposed module
Even now my xzp still have sot around 6 hours with 15% battery left. With everything enabled like x-reality, auto brightness, mobile data.
Btw i'm using existenz v10 cusrom + DT2W Kernel
