Battery Life / Recharge Time?

I recharged my phone in an hour when it had just powered off by itself for being too low... I used it for like 5 minutes and it was already down to 80%... Bad battery?

Sure sounds like a bad battery.
Just to make sure...
1) make sure you don't have some app that is running GPS
2) If not needed, try turning off BlueTooth
Those two items will drain battery faster than usual.

I sometimes find the battery is really inaccurate, depends on if the phone's running hot or whatnot...
Also you might want to get a task manager and periodically close all the apps (some apps have a one-click kill all widget), and turn off syncing, gps, and bluetooth

Battery indicator hasn't always been accurate or me - even with a brand new battery

There are several apps/widgets that are poorly coded which cause high battery drain as well.
Try only using stock widgets as well, I find that helps alot.

Yea, the only Widget I run thats not stock is Beautiful Widgets Home Small, set to update every 2 hours.
I have bluetooth and GPS off always unless I'm actively using them. I just seemed strange it was so fast to recharge mainly.
I've noticed the battery capacity jumps up and down depending on what you are doing. For example if I disable 3G, it jumps up, if I enable it, it might jump down 10% briefly then go back to where it was...
Very strange.

Also, I find the app Juice Defender (free version) is a life saver. My battery life has gone from around 12 hours to > 2 days since using it.
What it does is disable your 3G AP and only enables it every X minutes for Y minutes.. I think the default is 15/2. The result is you still get your notifications (a few mins behind), but your battery lasts WAAAYYYY longer.

Thanks for the tip!
Now going hunting for "Juice Defender".

yeah, juice defender is great. The free version has limited options but the default options really save battery life on my vogue.
I read a while ago that there was a problem with the stock text messaging app. Is that resolved? I use Handcent SMS, but i don't know if it is good or bad for battery life comparatively.

JuiceDefender is fantastic, it works. Except you can't be listening to anything and have it running (music, podcasts, etc...) because when it kills the 3G connection the audio stops. I've talked with dzo and looked at the code myself and I don't see a way to keep it from happening unless there's a way to kill the 3G connection without issuing an 'ATH' to the modem or somehow ignoring the 'No Carrier' message that follows it...

this happens no matter what music player you are using? I was hoping it was just Cube, but had not gotten a chance to try with other media players. Is there a way to create an ap that autodiables jucedefender when you play music?

Not that I'm away of... I just manually disable juicedefender before I start playing my music... and HOPE that I remember to turn it back on...

I am not endorsing this battery/seller/etc or that this is the battery to buy in any way. Just came across this opportunity and wanted to put it out there for anyone that wanted to check it out:
http://www.amazon.com/UTStarcom-Ext..._28?ie=UTF8&s=wireless&qid=1274569716&sr=8-28

[Q] Battery draining even in sleep mode

Guys, I have been using the Incredible S for the last 5 months now and my battery always used to last the whole day. In sleep mode, it never used to drain more than 10% through the whole night. I don't use GPS, Bluetooth very rarely, no Wi-Fi, brightness @ 30%, backlight @ 15 secs.
However, over the last 2/3 days my battery is draining like anything. Last night it drained from 45% to 3% through the night without any usage.
Can someone throw some light on this issue

Probably an app you downloaded keeping your phone from going into deep sleep

Yeah what applications do you have installed? Words with Friends was the biggest culprit for me.

Get the application cpu spy to check for deep sleep and use a monitor app to check for high cpu usage from apps

Thanks for replying guys!
Haven't really downloaded any apps recently, Downloaded ADW Launcher and then uninstalled it.
Can you guys help me with some monitoring apps and is Cpu spy an app?

is your mobile data turned on? if not, presuming u have downloaded anything since u bought your incs, chances are your battery is "leaking" charge. replace the battery

I have quite a few apps; facebook, ebay, whats app, Go SMS, sky sports and news, titanium backup, fonts installer and currently running VU v2.39.0. By midday I have lost around 40% battery from full charge over night. I'm loosing about 1% every 5 mins!
Have stopped using live wallpapers, unchecked auto sync and always-on mobile data, using battery booster to control wi-fi so it is not always on, do not use bluetooth, brightness less than 50% and screen timeout set at 1 minute but I always lock it anyway. I have also installed system tuner, but to be fair I do not really understand it all, especially governors and frequencies ect. I have also calibrated the battery recently and wiped the battery stats a number of times.
Do I have to uninstall these apps in order to get half decent battery, which for me kind of defeats some of the objects of having a smart phone! Sleep is when the screen is off yes?

With system tuner you can check how much cpu an app has been using. Very high amounts usually means a rogue app that isn't allowing your phone to sleep.

Do these programs drain my battery

Though I know gb roms don't have such a great battery life it seems as if my battery is draining faster than it should despite changing to different roms, calibration, changing batterries and deleting apps or widgets . (Currently gamrez rom which has been said to have quite a good battery ) .my battery drain is about 10 percent an hour with a mild to idle use. it's been like that for my old battery and even for a new 1800mah. I suspect there might be a program respobsible for this.
Since these programs dont appear under battery usage, yet are considered services I think the culprit is one of them.it might be that one of them is preventing the phone from going to deep sleep so the battery drains when idle.
My running programs are:
Go launcher
Go keyboard
RocketDial pro
3G watchdog (sync every 15 minutes)
Call meter 3g
Adaway
Auto rotate
Sanity (only for auto handsfree)
Bussiness calander free
(before anyone blames it on these three, it happenend even when they've been removed )
Viber
Whatsapp
skype (service autorun disabled and usually not logged in)
No stock email
Also as far as widgets are concerned I have a widget for callmeter usage. 3g watchdog and bussiness calendar agenda. and sync for google stuff , whatsapo and viber.
I know it's a lot of stuff, but I've been tweaking and picking these programs since I really need their functionality.
Under battery usage most of it goes to display (about 50%)
People report better battery under heavier usage so something most be wrong.
Didn't have time or nerve to switch to ics but I'm affraid it a program so it won't make a difference

There are many system monitor apps available on market.. install one of them and try to find out what is draining your battery.. sometimes it turns out to be the least expected app/ service..

Hi,
install "Quick system info pro". In the info tab, tap "battery", then "battery history" and you'll have all the info you need.
Pierre.

Thnx, I've install badass battery monitor in hope to put an end to this mystery. Still, I was hopnig someone could rake a look at the list i published and maybe shed some light if anything pops out.
I'll keep waiting for more replies.

Go keyboard
I've just installed go keyboard and typed 'top -m 5' to see top cpu users. go keyboard was in first place. After one hour phone idle, battery has been drained by 5% Maybe it's just my cfg problem. But.. that's just an observation.

This is just an idea and I might be totally wrong.
But doesn't it take like 10min for a phone to go to deep sleep?
So if you got am app syncing every 15min you get out of every 15 min 5 min of deep sleep.
It's to say you would normally have 50 min of deep sleep in an hour whereas you would have like 15 min.
And you could check the percentage of how much battery an app uses through the battery info in the settings and to check if your phone goes into deep sleep you can instal the app CPU spy.

Battery is terrible?

I have been using my phone on wife since about 7 am. Since then, I have done maybe an hour of browsing on chrome, installed an app or 2, watch a short YouTube video, checked my email once, and played a game for 5 mins. I saw other people's battery stats and it says they have 20 plus hours of talk time? Mine says there is only 3 hours left. Is it possible I have a faulty battery? I'm also using juice defender and power save along with the brightness all the way down. I'm running android revolution hd with elemental kernel. I have the att version. Thanks in advance.

Depends on what rom your on and how long you have had the phone

I find that based on my usage habits that I get terrible battery on Android Revolution v12. I always find myself going back to a rooted AT&T Sense build, and I'm able to pull 3 hours of screen-on time with 20% left.
Be sure to use a Wakelock Detector to pinpoint any rogue apps that are keeping your phone awake when it should be sleeping.
Also; be careful with those "Juice Defender"-type apps, Android has come a VERY long way in managing RAM, and resources since 2.2 (Froyo).
Report back with any findings

Don't mean to hijack the the thread but im having a rather peculiar issue 3g and wifi are eating away my battery like a percent for every 2-3 mins that also while only browsing web nothing else in the background can anyone help . Also im on stock rom , no root and s-off
P.S auto sync is off few apps have been disabled like (play store,facebook , google + and google search and few more)

jucie defender and power saver lol over kill i bet they are working against each other

I have about the same hours on stock rooted AT&T 1.26.502.12. Updating to stock rooted 2.24.401.1 has about the same hours, but it's only been about a week and I'm constantly flashing the new ElementalX kernels, so it hasn't settled.
Also, running at 1.2ghz and intellidemand/fiops.

I think my battery might just be bad

what? or do u mean WiFi

you should use GSAM or wakelock detector to view if something is killing your battery, I have a very VERY good battery life specially since I updated to 2.24 firmware, i guess you don't have root

Check the ss I posted of gsm, and I do have root. Also, what does it say in talk time left in gsm battery monitor when you have full battery?

My battery life was great until i flashed new firmware. i'm on ARHD ROM and it was great on 11.5, with 12 i started using nova launcher and now battery life isn't as good as it was previously. Have you experienced changes with your battery life while using some custom launchers? Or that's rather caused by new firmware/rom/radio/etc?

if i was you I will do the following
-update the **** out of your ONE (firmware and ROM)
but since it would be to laborious, I probably do the following:
1 Factory reset, in android (backup your things becaus it will be erased if you do a factory reset in android, or just dont do it!!!!!!!!) and in recovery (or only in recovery =.=
2 Install a custom rom that is near to a stock rom like ARHD (do it two times with full wipe)
3 with titanium backup remove (after do a backup) the htc bloatware crap that you dont use
4 with titanium backup remove the gapss that you could download from playstore, like youtube, gmail, and specially MAPS
5 GREENIFY all apps that you dont use commonly, you will be able to greenify apps like maps and youtube
6 DONT USE SEEDER OR ENTROPY MODS!!!
7 DONT USE battery saver apps
8 set battery saver option: cpu, vibration, and if you can get use to, mark the data connection option too...
9 Use lagfix app...
10 download Trickster MOD and set you gobernator to MSM-DCVS (this could cause a little lag when you turn on your ONE)
allow to pass one day with you fresh rom, and the following day check how is your battery life
11 if you still have a not soo good battery life, try disabling media storage in apps configuration menu, maybe you have some corrupted media files that dont let media storage to scan all of your media and check if your battery life improve, if so, you should clean your media files, (because let disabled the media storage app have very high side effects)
optional
12 use mods related to a battery life of pimp my rom
13 disable location update from maps, and all location things from configuration (enable when you need them)
14 disable all autosync things that you could do manually, like dunno facebook
15 disable auto update hour and date
+++ disable google now
more optional sh*t
16 when your phone is fully changed in android, turn it off and let it charge until the led change to green, do that one time every two or three days
17 battery stats wipe whit any app of playstore
18 manage your brightness screen manually (its easy and fast in android 4.2.2)
fin...
normally i get 5:30 and 6:00 hours screen on time with a very good use (3g) but one day i get these results
BTW download the app batteryDrain is very good to check how your battery is draining
...And set the option in GSAM that show statistics since last full charge, and dont plug your phone because it could reset the statistics (well if you are reviewing your BLife that could be a problem since stock battery report of sense is almos usless)

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.
