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.

Battery drain issue?

Hey guys,
so I recently purchased an International HTC One X and hsve loved it so far, but I think the battery is draining too fast.
On standby, it drained from 93% to 89-92% in 8 hrs which I suppose is good, but while using, it drops pretty quick. I wanna know how many hours or how much percentage does your battery decrease by while on standby or during use?
By the statistics I have provided, do u think there's anything wrong with my battery?
PS: I used the built in battery app, go to settings>power
Thanks, Id really appreciate it if u could help out since I'm worried if my newly expensively bought phone has something wrong with it or not, ill hit the thanks button

Battery drain
I'm currently on Leedroid' ROM and the behaviour is similar to what I had with the stock rom and looks like the folowing:
Data or WiFi on, autobrightness on, autosync off
Hangs a litle on 100% then dops abruptly from 98-97% to 80% in about 4-5 hrs with a screen time under 30'
from 70% to 30% however, the battery drain "magically" improves giving 6-8 hrs of standby including 2 hrs of screen time of which the most is used to browse the net via 3G.
At the moment my stats are: 13h 50' on baterry, 2h 15' screen time, 21% left
I got a steep drop from 31% to 21%, just as I was checking the stats for this message, but bare in mind this is the first run with Leedroid (flashed last evening) so I expect things to improve.
After 10-12 days on the stock rom I remember getting some 3-3.5 hrs of screen time within 16 - 18 hrs total before reaching 10%.
So i suggest, give the battery a little time to settle, then adjust your usage habits according to what you get (like turning autobrightness off, data off etc).
I for one am waiting for some stable kernel improvments regarding the tegra power mangement (sounds cool, have no idea what I'm talking about and I expect to get some 20-30% more screen time within the same time period (18-20hrs).

I've been running a few battery tests. Last night I wanted to totally burn out the battery so I used it down to about 5% and started a youtube movie streaming over wifi at full brightness. An hour later...... it finally died.
The companion core on this thing can really confuse you are testing standby time or music and video playback.
I want a mod for the phone where I can toggle it to use 1, 2, or 4 cores. To the OS, it looks like core0 is also the companion core.

Thanks

Thanks for the reply
so do you think there really is something wrong with my battery?
i read on a popular android website that they played a video on mx player in loops and it lasted for 6 hrs and 6 mins, which makes like 17 percent for every hour of viewing. I downloaded mx player, gonna watch a movie, and hope the battery drain is on par
The less battery doesnt bother me much, what does is that im worried that there MAY be something wrong with my battery, gonna try out for a day or 2, gonna see if my results can match urs, thanks
just hope theres nothing wrong with my battery
PS: i have everything stock, i unlocked bootloader, flash CWM5.8.x.x but returned to stock later.

So the browsing drained about 70% of the battery right? Suppose those 11 hours of sleep took even 10%, and u have 21% left, so u spent about 70% on the browsing right? Thanks

when you charge to 100% it drops down to 95% then charges back up to stop over charging, who ever it doesn't show you the % it just says 100% thats why you can lose ~5% in a few seconds when first taking it off charge.
yesterday i got 14 hours 9% left and had just a little over 4 hours screen time on leedroid 5.1.
playing games is a massive drain

Thanks, that's what I hope to achieve. I did a factory reset, will fully charge and see how it fares tomorrow. Btw, I don't play games on battery precisely because of the massive consumption.

Battery Fix
I had a pretty serious battery issue during my first couple days with the phone, where the battery drain was extremely fast and inconsistent, sometimes dropping 5% at a time and giving me maybe 8 hours of life total.
The issue was that the battery tracking in the phone was messed up. When you go to Settings>Power, the default setting for "Fast Boot" is on. This seems to mess up the way that battery drain is tracked. I fixed the issue by turning Fast Boot off, charging up the phone to 99% (it wouldn't reach 100, that's how bad it was messed up), then restarting it. Now, it works perfectly and easily gets me through the day with moderate/heavy usage; I watched a 30 min video streaming from youtube of wifi and lost only 7%.
The downside is now the phone takes 5 seconds longer to start up .

I did that, and streamed on youtube for 30 mins, lost like 9 percentage, is it good? or is there something with my battery?

All of your battery issue will be sorted out people..don't forget that One X is still running on GB kernel n so is transformer prime..Nvidia n HTC are working on the ICS kernel..n once they are out with it our HOX is gonna blow away everything in the Market in both performance n battery life :beer:

That's perfectly fine. Battery drain will never be perfectly consistent (perhaps your video had better graphics/resolution than mine did). Looks like your battery's OK now.

Awful G3 Standby time

So ive been using my G3 for about 10 days now and have been getting pretty bad battery life at work with airplane mode on and only wifi and wanted to really test out the battery last night by leaving it unplugged overnight. I usually keep my phone plugged in overnight but since it was the weekend i was home on saturday and it was in the charger for basically the whole day i decided to test the battery. I unplugged the phone at around 2:50 and took the screenshots below at around 8. I lost 29% of my battery during that time and i was SHOCKED!!! my phone was on 4G however i have really good service where i live and was on 4-5 bars all night. the phone didn't have bluetooth, wifi, nfc... ect active. The phone was on 15% brightness (if that even matters since the screen was off all night). Before i took the screenshots i went into battery and saw that an app called "lyft" was said to use 70% so i uninstalled it before taking that screenshots. I really don't know what i should do because i am rooted and have already installed a tempered glass screen protector. Please help if possible!
Screenshots: http://imgur.com/j3kbWyJ ; http://imgur.com/EZekrFw
Edit: Its 9:37 now and around an hour and a half after i uninstalled lyft. I am now at 68% which is better than last night however still pretty bad considering i had a screen on time since last night of just 6 minutes and 29 seconds. Here are the screenshoot updates: http://imgur.com/azs4SWK ; http://imgur.com/DNZu8n9 ; http://imgur.com/qrz4nrx
Edit #2: Battery life continuing to drain fast i have 59% which means i have lost 9% in less than 2 hours of virtually no screen on time. I am very concerned and don't know what to do? If anyone has had this issue please let me know. Screenshots: http://imgur.com/8nOgVgj ; http://imgur.com/lSywjj4 ; http://imgur.com/KqGYAVK

Looks like wakelocks only. my G3 has a great standby time, overnight with WiFi on i lose 3% or so for 6hrs. SOT is not that good, but the phone Deep sleeps well.
Try removing unnecessary bloat.

Battery usage

My battery stats have improved greatly by turning off location completely.
Took it off charge at 6am and with heavy usage
YouTube internet calls etc
still have 65% 16.5 hrs later.:good:

Just starting to play with battery use on my new G5. 100% charged 10 hours ago just before bed.
On a day to day basis i am a pretty light user. Calls and texts mainly.
Left phone unpluggged so it slept and 7 1/2 hours layer its at 93%.
20 mins music and email checking 19 hours in its at 88%.
Have Greenified much in the way of apps which i think improved things. Compared to the Sony i had the G5 seems to have ok battery life.
Its certainly in the useful, full day and better range.

Is yours rooted? I tend to get 5+ hours screen on time sometimes 7 which is amazing for a phone this cheap.

Same here, I have about 4-5 hours of screen on time with greenify, non-rooted. I'm a regular user, messenger, emailing, browsing, spotify etc. I'm also using Adguard which has its impact on the battery but a small price compared to having ads all over the place

Nope, no root as yet. And actually i may not depending on what ROMS become available in the future. Pretty happy with the way this is setting up and Android 7.0 stock. I think i may well leave it unrooted until after Android O hits and see where i go from there.

i'm rooted and the battery is very good, i got 7,5 hours SOT, usually i have 5-6 H of calls and 3H of SOT, 2 sims active, wifi and 4g always on, and the battery is 20-25% when i put on charging from evening to the morning. Very happy with this battery

Very good battery for price of the handset

I don´t know it´s a isolated case, but since i bought the phone, the battery is pretty bad, yesterday i tried to charge with another power adapter and my battery it´s lasting longer, anyone have this same problem?

Sometimes this happens to me.
When i keep my phone overnight(Battery Saver ON) even wid a charge of 60-70%, next day mrng, the battery is completely drained and phone is OFF. This doesnt happen daily, happens only sometimes. Any guesses why dis happens?

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 Samsung Galaxy S8+'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!

Hello. I've recieved my mobile phone about week ago and there is one problem that annoys me. While the phone has lcd turned off, it drains a lot of energy. For example, yesterday I slept 7h and the battery decreased from 80 to 50%! I've tried almost everything, offline mode, aod off, battery saver mode etc. Any solutions?

Not that much

I think it's a lot ! I've seen many baterry usage screenshots and I was impressed. But mine is some kind of joke. I can't even use my mobile phone often at work because it's dead from 8 to 16, with all options turned off - aod, sync, gps etc. Also with baterry saving mode. Please guys, there must be a way to fix that.

Maybe try and disable bloatware using BK package disabler. It helped for me after disabling a few things

Unfortunately it did not work. I've tried everyrhing..

with only wifi and sync on, battery drains 3% from 11PM to 6AM

4G on
Wi-Fi on
Sync on
Over night From 12 to 8am is 2-3%
Not more.

there's a hundred settings for better battery life, putting apps to sleep, app background data, app data while data saving, notifications, permissions, etc etc etc....

Change network mode to 2G only. You will see standby consumption go from 1-1.5% per hr to .3-.5% per hour guaranteed. Obviously more drain if using always on display and/or other heavy features. Works perfect for me as my s8 is my secondary phone and don't need 4g.
ps. sot currently was like 6 mintues so didnt post screenshot of that, although im able to get around 5-7hrs sot with about 24hrs total use time. Also rom is renovate ice note 8 port ver .1 all stock settings otherwise. Also i got pretty much the same battery runtimes with stock or custom roms. Same usage with lte/3g/2g setting enabled got me nearly 5/6 hrs sot with around 16hrs total usage but really standby was affected by this setting change.

Not touching the phone, I lose about 10% per hour. A thirty minute drive to work, with Pandora the only app in use, it runs through somewhere between 15-20%. I've tried everything, including telling its mother and using the kitchen sink, but nothing helps. One day we weren't busy at work, and I forgot my charger at home. By 11am I was at 9% (that's after leaving the house at 7:30am) and had to make a run to Walmart for a charger. On a normal day, I have to charge it 2-3 times. On an extreme use day, I have a constant tether.

Not that much

I lose 3% or so over 8 hours of sleep. Make sure you go through your battery management and options to end draining apps when left in the background.
Stock US unlocked S8+

I'm going to leave my S8+ (unlocked) history so that others can relate and solve as i did:
Bought mine with a German ROM (DBT), and as soon i as connected it to Wi-Fi it got updated to QH3 (latest).
Notice immediately a "Android System" drain that would take over almost 50% of phone sleep time. After some days decided to a "Reset / Factory default" but same story, drain ...
Solution ? Flash different region software (PHN - Netherlands - G955FXXU1AQI7 )
Now it sleeps like a baby and "Android System" remains very low.

Imm experiencing huge battery drainage since the new firmware update......no clue why
Oh and my phone is warm in idle and becomes quite hot when doing low intensity tasks such as loading this site

It's too bad

If this true, I may give up to purchase one. I don't like to bring a power sink. And there is not always have a store that I can charge my device.

That's been my, my son's, and several other people's (in the root threads) experience. There are a whole slew of people that have great battery life with root, but mine is abhorrent. I actually went back to stock, and have been astounded how much longer the battery lasts compared to having it rooted.

Use Tasker!

Program Tasker to switch off all internet access, auto sync and wifi and Bluetooth. Once switched on, the phone will regain all functions. In a 12 hour shift, with occasional use, I lose about 20% of battery power.

I like Galaxy S8
This is best phone I every wanted. Galaxy S8 is best device in its own. No one can beat it.
