[Q] Battery Life Issue

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 unusual battery drain from the screen?

Hello everyone! I just switched to my first Android device and am truly enjoying the experience. I can't believe I was using an iPhone for so long. I finished draining my battery for the first time and recharged it and am draining it again. My phone indicates that the screen is consuming around 66-70% of the battery drainage while everything else is quite low such as the Android OS taking up about 12%. Is this typical and does it improve over time? Thank you for your help.

this is normal but seems like that is pretty heavy use. if your phone was barely used then that is not normal.

I am going to further diagnose this. I have my brightness set to auto. I wasn't really using the phone that much. I flashed it to the yakju build and it is running 4.0.2. Is there anything I should do to test the phone?

what is your screen on time

I'm looking at
9h 56m on bettery
Android OS 33%
Phone Idle 30%
Cell Standby 22%
Screen 9% (on time 9m)
Wifi 5%
Google Services 2%
This is after the phone being nearly untouched most of the day, no calls or texts and nothing being done but checking my email once not too long ago. It's on Auto-brightness which sucks because it appears to be on the darkest setting but without that my battery seems to go from full charge to 50% in 1-2hours with moderate usage (Browsing the web, Checking email, Browsing Market, few phone calls and texts) and it sucks that I feel like I cant play with the phone because it'll be dead when I need it and without Auto-brightness the battery dies even quicker.
Almost feel like I need to be tethered to the charger.

you either have really bad signal and/or 4g and/or a process keeping the phone awake, in your case the high cell standby time suggests the first two

This seems common for the lte version. The gsm version gets very good battery life especially idle drain. Turn off lte is your best option.

Assuming you have the screen on a lot then yes. Those big beautiful screens are hard on a battery.

If you're on the LTE version using 3G only you will get around 3 hours screen on time MAX.
GSM version you will probably get 3-4 hours screen on time per charge.

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.

Another battery thread

Running CM10 Wild into the Night.
If I let the phone sit without touching it, I get an average drain rate of about 10% per hour, lasting me about 10 hours on a full charge. However, the battery decides to have a field day as soon as I perform the occasional texting and web browsing.
As shown by the screenshot, culprit is the screen. However I have the brightness set way down (about 1/4 from the bottom) and the phone goes to deep sleep 70-80%. According to Gsam battery monitor, the screen uses about 60% of battery with only around 52min of on-time during the 5 hours that a full charge lasted.
Something is definitely up. When I was running stock Touchwiz, AndroidOS used to be the battery hogger. But now the screen has taken over the crown on CM10.

Screen will always use the most unless you neve use the phone. How old is your battery? Does it spin?

That sounds like you need a new battery. 52 minutes is no
Where near long enough
. or possibly with the screen on some app is running the CPU full speed
use CPU spy and leave the screen on indefinitely after unplugging it from the charger at full battery, and see if the highest CPU state is being used for the entire screen on time after you unplug it.

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
