[Q] Is my battery broken?

Hey I have just bought HTC One 2 days ago. Compared to my old Sensation XE battery life completly sucks. I usually use phone without battery saver, on auto brightness and with Wi-Fi/3g turned on only on demand. Today 8 hours after unplugging phone from the charger I only have 26%. Screen was turned on for 2 hours and 45 minutes only and Wi-Fi worked for 3 hours and 46 mins. I might also say that I did not charge my One before usage to 100% as HTC advised. Was that very crucial? Do you think that phone might be broken or I should just give him time to settle baterry better.

That's sounds like what I get. I turn off mobile data when using WiFi and vice versa. I always use power saver unless I'm 3D gaming. Which is only on the weekends.
I've had mine for 3 months now.
I've seen people get 7:00 screen time on stock unrooted.
I think my battery's broken too. I can barely reach 3 hours of screen time. With 2 hours I get like 11 maybe 12 hours of on time. Something's wrong with our phones...
Does anyone have any suggestions?

Does anyone see a problem with my battery I have been on wifi the whole time with brightness at 20%.I never had this bad of a drain before and all I did was look at facebook for maybe 5 minutes.I also closed the app after I was done using it.

Your battery stats seem on par with me and the OP. Seems that only a select few phones get decent battery life.

My kernel (android os) has been in the 25-35% range,it has never been that high before.

battery life lousy
I get pretty horrible drain too. I charged it to nearly full around 7:30 last night. I took about 2 minutes of video, sent one text, and checked my email 3 times. After that I went to sleep and the phone sat idle. At 6:30 this morning, I'm down to 9%.

Wow, that's real bad.. When my phone is off during night maybe 7% is gone. Then again I'm rooted and use greenify aswell as battery doctor if that has any affect.
On screen time seems like my battery drains pretty fast too though. After 2 hours of music and surfing and watching videos I guess atleast 40% would be gone.

My battery life became horrible, too. My phones loses 4% per unused hour. No App seems to be responsible for that drain. Flightmode or powersaving mode ain't making a difference. I hope we'll find a solution for our drain.

@Racingmatt your power management services is on for quite a bit. do you have alarms.? i would bet that you either that maps location enabled or something of the sort. cause you also have NLPcollector on for around 40 minutes which is a bit much. also i would turn off GPS if your not actively using it.
@Rachorid how are you setting up your wifi? is it set to always be on? or set to turn off when screen off? you have alot of wifi wake. might be due to that. i know when i'm at home my wifi actively pings all devices connected which will force wake up my phone. yea its a bit annoying but i live with it. otherwise i just keep my phone plugged in.
if you both can get some SS of alarms i can give you a better idea. and when you SS the alarms make sure to click on the ones with the most wake lock so i can see the secondary screen that shows what the actual wakelock command is happening.

Here are the latest stats. As you can see many Google wakes.. removing Maps/Now/GMail/turning of Location (a few days ago) had no impact on my drain. The 2nd app on Partial Wakelocks was used actively.
I also disabled Wifi for about 2 hours.. no impact, too. Flightmode also had no impact (a few days ago).

The reason I didnt give you a alarm ss is because I didn't have any alarms when I went to the alarms section. I also had all locations services including GPS enabled but I just now disabled GPS but left network location enabled I'll give you a screenshot later so you can see the differences

I know exactly how you feel that's what happened to me,u was expecting so much from the battery and it turned out to be the worst..give ya some advice...3g drains the **** out of the battery ,so always jeep it off and turn it on only when you wanna use it...that way the battery will be acceptable... Also flashing a custom Rom would help...o recommend arhd

I had awesome battery life a month ago with Wifi always on, auto. brightness and every app on hourly sync. (I have my phone since 7th of march) Sometimes I didn't lost a percent over night (8 hours) and I just don't know what it could be because I didn't install another app and no app seems to be responsible for that stanby drain. My on-screen battery life is still good. It also doesn't matter which ROM or kernel I'm using.

Here is my latest stats after 12 hours with 5 minutes of GPS use (turned off when not using)and network location on all the time with 3g/4g on all the time(turns off after a period of inactivity) . I can't give you a alarm stat because I'm not rooted.

Lithium-Ion batteries used in today's smartphones need atleast 10 cycles to show optimum power
so hold on until 2 weeks then you will get the full performance
i get 2 days of battery on my HTC One (since i dont have internet on my Simcard)
its 2G connection and auto Brightness and switched bloatwares off
i use Android Revolution HD 12.2

with normal use 3.6%/h is pretty reasonable. how much screen on time was that including?

Screen Brightness kills battery more than you'd think

So the poor battery life on my Note 4 might have more to do with screen brightness than I would have expected. Unfortunately, most people posting their SOT's aren't doing it in a very scientific way, so it's hard to know what we should expect from these devices.
Here are my battery test results using PCMark for Android https://play.google.com/store/apps/details?id=com.futuremark.pcmark.android.benchmark
In one test, I put the screen brightness to 100% and the results were pretty dismal. In the second test, I ran it at 50% brightness, which is brighter than the Note 2 at full and the results were much better.
I use Auto brightness during the day, which might explain my poor battery life, but I'd love to know what others score on PCMark are (it does run for 5+ hours!). I do keep my background BLACK, as well as using black themes on everything I can - for apps that only have white backgrounds, I use AutomateIt to invert the colors automatically. I would have thought these black backgrounds would do more, but it really comes down to brightness it seems.
I'm using an Exynos N910U model and left wifi connected while doing this test - 3 google accounts are synced on my device.

thanks for tests im using my exynos version on auto brightness and generally get 6 hours SOT. i saw on alot of people s stats and people who has problems generally has google play services on their battery usage list and it definetly shouldnt be at there... its probably about location reports to google every1 should disable it from location settings it doesnt break anything.

Yes, location can be an issue, but I think that impacts standby time more than SOT. Currently I've done the following to help with location-related issues:
- used lion tamer (soon to be called amplify) to slow down NLP wakelocks.
- set my location settings to powersave mode
- setup AutomateIt to turn on GPS when I'm in Google Maps (I'm usually plugged into the car outlet, so battery isn't a concern while navigating.
- Greenify stuff like Google search, Maps and several others.
I like and use Location Reporting, so disabling it outright isn't an option. My standby usage is very good at usually less than 1% an hour and my wakelocks keep my device awake usually less than 6%, but I'm still working to lower that number.

last night with 10 hours sleep time. with wifi connected sync was activated for 3 mails. i just lost 2% and i didnt do anything special like you did. no greenify no root nothing i couldnt even install wakelock detector cuz its broken on kitkat without root.
. i just disabled some useless stuff like samsung store etc.. everything else is working. and on my car i generally listen music over bluetooth

Lux could help

Before I started tweaking, I was getting around 6%-9% drain PER HOUR! Disabling stuff without root only got me so far, then the xposed tweaks and Titanium Backup had to be used.

like i said i dont know whats wrong for some people its probably something you installed(skype maybe) or mostly about location reporting. even last night i left my phone at 90% when i get it this morning after like 10 hours it was on 88% like i said earlier wifi was connected no power saving etc just normal idle time nothing special.

I was testing without any apps installed (just whatever I used to record battery consumption) and it was crazy high. Then I started adding accounts and apps, tweaking and I got my standby time to be much lower, but SOT leaves much to be desired. I'm going to try using the manual brightness and see if there are any differences - I often find auto brightness to be too bright or too dim! No "sweet spot" found! LOL

Greeny can also help but may need root

I'd suggest changing the settings for your Battery Monitor Widget app. AFAICS it polls every 10 minutes so a wakelock occurs every ten minutes to save the data. Use something like an hour and see what happens. Also would highly recommend BetterBatteryStats, a free version is available here for members.

I'll try that, although that might only improve wakelocks, not screen on time.
BBS never worked right for me. Always complaining that it couldn't retrieve the stats or falling back on something else.

Wait, with the screen off? Then you have something horribly wrong with your device. Mine did a few % over a night. With nothing done to the phone to conserve battery at all. Snapdragon, though. With the update.

I loose only 2% for 7h of standby last night.

We are seeing a trend I think, I noticed that it's mainly us 910U users or exnyos users complaining about battery life. So it must be something in the 910U rom?

I've got a 910F and I get 6 hours screen on time maximum :/

Doesn't happen now that I've rooted and applied my standard tweaks, but I tried a factory reset to see if I could correct the high standby drain and was not successful without these tweaks.

I have 910f and i got same issues with my batt.
i've tried clean system, root, custom rom. Battery is always draining higher than some people.
As i said in other thread: some people have an issue, some have great battery life. And nobody knows why

Maybe it's the guys who keep it stock and don't root, custom rom and "tweak" that get the good battery life.

Delete it pls.

T700 Tab S Standby Time!

My Tablet lasts 2 days before its totally dead with ZERO USE!
Updated to 5.0.2 as i hoped this would fix it. No change
Lost 10% battery while in power saver mode in a few hours!
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!

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.
John.

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?

OnePlus 3T SOT only 4.5 ish hours

I have got my one plus 3t about 2 weeks ago. I have noticed that it's screen on time is never over 4.5 hours. I've read people saying their op3t SOT is over 6 hours.
Currently it's running oxygen OS 4.0.3 (Android 7.0)
I can't compare against the SOT in marshmallow because after I bought it I instantly upgraded to android 7.
I followed some steps suggested in several forums that should fix any battery drain issue such as wiping partition cache from recovery mode, clearing Google play service cache, turning on doze mode from DEV mode. It didn't get much better.
My usage pattern is mostly light to moderate. I use Facebook, fb messenger, aqua mail as default mail app, deezer for music. I am normally on my wifi most of the time. I turn on data for a small portion of the day. I turned of location service and Google location history. My screen brightness is set to about 20%.
Can you help me understand what's the underlying cause? It's not that I'm not happy with the battery performance. It lasts easily a whole day for me. But having more SOT would definitely be great.
Note: Unfortunately can't share my screenshot here as i'm new to this forum.

o.o you use Facebook and Facebook Messenger. To my knowledge they both encompass a whole lot of wakelocks that keep your device running after you put it to sleep. First thing would be to either greenify (if it will help) or delete both of those applications. I dont use em, but if you go to any battery saving thread on android most tell you to do something to keep those apps from running unless you want them to, instead of just, on, all the time doing meaningless things like holding the phone awake.

Without Facebook installed, only whatsapp and surfing, I am getting around 7,5 hours SOT. I'm on freedom os open beta, stock kernel.

on oos rooted with elemental x kernal, whatsapp snapchat and instagram only no facebook or anything like that, i am getting 6 hours screen on time with a bettery life 2.5-3 days 100% to 10%. Obviously i am not addicted to my phone the screen is on about 2 hours a day on average sometimes 3. I have no idea how much screen on time i could get in a single charge if i was a heavy user but i reckon it would be high based on the rest of this post.
Edit: For those on franco kernal i tried it and it was not even close to elemental ex i was get 1.5 days battery at best and that was with the battery profile enabled.

instead of using greenify, would it help if I use the Aggressive doze mode? It should put every background app (including Facebook and FB messenger) into hibernation). Shouldn't it?

Greenify makes a massive difference. I was using naptime that puts aggressive doze on as soon as the screen is switch off and i was still getting more drain that i wanted (about 3 percent in standby).
Now people will tell me greenify doesnt make a difference, answer me this then. How do i have a screenshot of an 8 hour period over night where i lost 0.1% per hour.

Standby in night seems use less power than in day. I think the reason is that you don't wake your phone at all at night.

Why does everyone find this so hard to believe. At night i would lose 0.6% per hour. With greenify i lose 0.1%. Greenify makes a difference, simple.

No, I believe you man. I use Greenify too. Just saying a fact that I observed. I thought you're comparing the day time drain with night time drain.

Help please ;_;

Is this normal for a note 8? Settings = fhd+ no power saving mode, aod and edge lighting off. I know i m getting way low than i should get , I saw people getting atleast 4 + hours of screen on time everywhere

lowering quality and turning off aod/edge lightning will only save you a few minutes, you may as well have them on enjoy the features.
The SoT is user dependant, everyone uses there phone for different things and in different ways.
Also your phone has been on for over 20 hours, im sure you would get the same SoT as the rest if your phone was not sitting (screen off) running apps in the background for so long.
Having said that spotify is one of the things you have used in that 20 hours and judging by the %4 it used i'd say you were streaming a fair bit, that obviously does not add to your SoT but your still draining the battery. if you use your phone mostly idle while streaming music why does SoT matter?
No one can "help" you here i don't think, it is your usage habbits, this is what you get im afraid and from what i can see its not bad at all
my only tip would be if you dont use your phone turn it off instead of letting stuff like facebook eat away at your battery all day for when you actually do want to use it for Netflix or whatever :good:
Edit: Also your only at %25 still can get a couple hour SoT out of that :silly:

That's normal, that's how you receive instant updates from emails WhatsApp etc Facebook is an idle killer. You can either put the apps to sleep so there not active while idle or turn the phone off all together when you don't need it. Like I said I don't think there's anything wrong with your phone it's normal not for me but it's normal for you.

Samsung has one built in.
Go to Settings > Device Maintenance > Battery
click 'Save Power' that will put your apps to sleep.
Also you can scroll to the bottom of that page and press 'Always Sleeping Apps'
and you can add what apps you want to that list and they will never run in the background while the phone is asleep.
Alternatively you could use an app like Greenify.

You can try "greenify" at playstore, it is free, and a donation pkg that further enhaces its features
