So I have to handle with this 4.5 hrs of charging time
4.5? damn you must run your battery down to 5%.
Entropy's kernel uses alternative charging logic that supposedly charges faster at low battery. I don't know how effective it is, but you could give it a shot.

Are you USB charging or something? No way should it take you that long.

Yes, I am charging from 5%, Even if I charge from 50 to 100 it will take more than 2 hours.
the phone is charging 22 to 25% per hour. I dont think a phone should to such a long time.

I didn't understand anything in this..
Try deleting the battery stats when you are at 100%... you can do this manually or with apps like " battery calibration" free on market, or go to system and delete batterystats.bin manually, try everything i guess.
I was having same trouble when i used to change between ROMS a lot now i decided to stick with Infused 1.6 Froyo did the "recalibration" with battery calibration app, and takes a few days for the battery stats to rebuild correctly again.
But now it hardly takes my Infuse 3 hours to FULLY charge.
And you can recharge at any point even if its on 80% or 95% if you have a power aroudn charge while not using... this batteries dont get "used" for recharging them before "time" they dont do memory you can recharge at any time.. there was a whole thread about that somewhere here on XDA sorry i cant post the link just maybe try the simple way.... recalibrate on battery calibraiton and give it a couple days to generate an accurate stats.
Also recharge while not using (working....eating...sleeping...)
If nothing works maybe... get a new battery? may be faulty i guess.
Hope it helps

Clearing battery stats does NOTHING on the Infuse, or any of the first-gen GalaxyS devices, or any other Samsung phone with the MAX8998 PMIC for that matter.

it's funny (sad?) that you need to say this over and over again every single day. you'd think people would come across another one of your posts, which are everywhere, where you said this exact same thing.
Then you need to figure out the common denominator because either your cable, charger, or you aren't doing something right.
That amount of time to charge isn't normal.
Have you also tried pulling the battery for a few minutes then charging it yourself full? Don't power down, just pull the battery.

maybe try draining the battery all the way to 0. Recharging over night interrupted. And doing it once more. Not sure it will help, but I'd try anything.

Install CurrentWidget.
In the settings, near the bottom, there are settings for "operator on value" - Set it to divide by 1.83.
Then plug in your device when it's discharged below 80%.
Currentwidget should report 600 mA if you applied the correction factor above. If it reports 1100, you forgot the "operator on value" settings.
If it reports 475 mA, your device thinks it's connected to a USB charger for some reason.

The problem is people keep on coming from other devices, and they've been trained so long by HTC devices (most of which use coulomb counter fuel gauges) that they need to "recalibrate" their battery and let it "settle in".
Note that the GSII may also require battery calibration - it does have an updated fuel gauge chipset. But ours does not.

12 to 13 % in 30 mins, ie 4 hours to full charge, that is the problem...
Is it the same with phone off and charging as with phone on
and charging
Sent from my SAMSUNG-SGH-I997 using XDA App
Phone asleep and charging and phone completely off should be fine. Phone in use will take longer.
Also, the reason I said to measure at less than 80% is because as you reach 85-90%, you hit 4.2 volts and the charge circuit goes into constant-voltage mode - in this region, charging takes longer.
Measuring time to go 10-15% is WAY too inaccurate for any remotely decent estimate of total recharge time. ESPECIALLY if that 10-15% is near the top of the battery. Our fuel gauge probably has on the order of +- 3-4% error. For example, once I saw it drop 10% in 30 minutes, but then it recharged 10% in only 5 minutes. The 10% "drop" wasn't real.
I have had horrible battery life, I've got a replacement battery etc from att and they REFUSE to replace my phone! I'm still under warranty, have no scratches, cracks or water damage, I bought my phone in december of last year, and my battery only lasts 6 to 7 hours! What can I do!

Yeah. My previous thread. About my battery problems. Don't post if you aren't gonna answer my question... Just saying.
I have had a battery replaced, I've reverted to stock rom, updated, etc, done everything I can, every fix etc. I can't get near the 30 hour battery lifes I can see. Why would I get 6 hours MAXIMUM no talk time, 400-500 texts a day, data lte and gps and bluetooth off, brightness down. Thats pathetic battery. Idk what else to do.
The reason Given for not replacing is that is the average battery use. But on the specs it reports 7 hours of TALK TIME.

How long would your battery last with data on? Whenever I leave
wifi on, my battery drains. For everything else, it lasts the whole
day without charge on moderate to heavy use with lte.
Maybe try your luck with a different att rep?
With my previous skyrocket, I would easily get 14 + hours.

Relax. He's only offering some information to help you. The battery life on your phone is on par for that device. I have the original Galaxy S II and I average about 8-9 hours with heavy use, and an entire day with normal use. Just about all dual core CPU Android based super phones are going to have mediocre battery life. That's just the way it is. You can always get an extended battery, which should give you an additional 3-4 hours of useage. Aside from that, there's not much you can do about it.
What exactly do you expect us to do for you? You've tried other ROMS, a different battery, lowering the brightness, etc. If they sent you another battery, that means you have two batteries now. That should be plenty to get you through the day. You could always try trading the Skyrocket for a Galaxy S II, which is a better phone anyways as it has the Exynos CPU and slightly better battery life.
BTW, 400-500 texts per day is a LOTof screen on time, which would e plain the 7 hour battery life. And leaving WiFi on will also kill ypur battery life. WiFi is a huge power hog. My guess as to why AT&T refuses to swap your device is because you rooted it and installed custom ROMS. (which voids the warranty). And believe me, they know if you did that because they check the custom ROM counter.

what is your screen on time? You sound like you use your phone slightly less than i do. Im lucky to get 5hrs out of my phone. Been this way with every smart phone ive had since the original droid.....and ive had a lot. 400-500 texts means your screen is on every couple of minutes.

I would agree with this. Display time is a huge battery drain. In fact, it's usually my largest battery drain (even more than LTE).
If you only turn on Wifi when it's available, then you will save battery because Wifi is more power efficient than 3G/4G. Otherwise, it will drain battery searching for a network. This also means if you use NO data, then turning off Wifi completely will save power.

Turning on and off your phone that many times will do it in six hours.
to add---talk time assumes the screen is off for that time.
Call them back again and tell them that now your phone got hot and then shut off. say that you used your friends skyrocket battery to see if device still worked and it didnt. they will send a new one.
make SURE you tell them that it just got hot, and shut off. now it wont turn on at all.
Also, if the person you are talking to wont help you just say fine, hang up, call back. still doesnt work? repeat.
Im really not joking. just the other day i had to call them 3 times just to send me a replacement device.
Good Luck!

No, not really much!
it's made for those lazy people those who don't turn off unnecesary feauture when not required.
for best battery use just one homescreen with only static widgets,no wallpaper, just one home screen,STAY MINIMAL. keep data off if not required, gps off, wifi off, bluetooth off, screen off time-15s and keep clearing often or kill apps soon after using them, if you want strict settings underclock too.
more or less those apps do same stuff i just mentioned and they take up some juice for doing that coz they always stay in background.
my battery got pregnant =)) , and I should use my phone while charging
Is good if I use such a Double power Battery?
Hi fellow Nexus owners.
I've noticed recently (past month or so) that my phone's battery life has taken what seems to be a significant hit. I was getting around 15 hours on a charge with light to moderate use. I am now consistently getting 10 hours or a little more.
I'm running 4.4.4 stock, WiFi on, GPS = high accuracy, and have used both ART (current) and Davlik with roughly the same results. I'm a bit disconcerted by the higher battery use by Android System and Google Play Services.
I contacted Google, and was offered warranty replacement. However, I'm not sure it's worth it. How does this compare with your battery performance? Is it expected for an 8 month old device? Thanks for your input.
one important thing, how much screen on time do you get? as how long the phone last between charges doesnt say anything, as we all use our devices differently. for example, i only see about 7-10 hours, but im a heavy user, that sees about 5 hours screen on time.
Go to the battery help thread in my signature.... Read the first 4 posts. If you need help still, post the recommended screen shots from post 4. ?

Turn your brightness down! i keep mine about 15-20% most the time. when i raise it to 35-40%, ill get 30-60 minutes screen on time less. also, wifi, bluetooth, turn them on only when you need them. speaking of wifi, go to you wifi settings, hit the 3 dots in the bottom right, press advanced, then disable scanning always available. this will keep your wifi really off when you turn it off. otherwise google uses it to look for your location, even when you turn it off.

Do your methods help 100% of the people that follow your guidelines? Just accept that the battery is only 2300mhz so by tweaking a few settings would maybe add in an hour of juice give or take. Believe me, I have tried everything suggested, and have owned this device since release, the battery is Underpowered when used to power up a 5 inch, 1080p screen. You won't find anyone saying the battery is way too overpowered.

If you get 1 to 2 hours screen time.... You either have a defective battery. A very poor signal while in data. Or a really bad draining issue from an app or something.
That isn't normal.... And is well below the average. Well below the low end of the average. And that's average with everything on... Every feature.

I have noticed exactly the same thing for around a month, and Google Play Services now constantly appears on my battery stats. I was fairly convinced it's an issue with the Google Play Services 6.1.xx update as I was getting this wakelock:
wake:com.google.android.gms/.auth.be.proximity.authorization.userpresence.UserPresenceService
Googling it reveals little.
As an example, at the moment my phone has been off charge for 26 hours with 1 hour 40 mins screen time and is at 10% battery. That might not seem too bad but I have a screenshot from around a month ago where I had 49 hours off charger with 4 hours 2 mins screen time. Like you, 4.4.4 completely stock unrooted.
I'm going to see if the imminent Lollipop upgrade magically fixes it else it'll be a factory reset for me as I've given up finding a cause.
Hi everyone !
I haven't seen this info anywhere on XDA, at least on this forum, but i think everyone should know this.
Not trying to take credit in any way, because OP made a terrific job at researching and testing, just wanna spread the knowledge.
Basically : Charging your phone at night or leaving it charging even while at 100% for a few hours will have a big impact on how it behaves and how your battery holds up.
Quick explaination : Since Nougat, you don't get the App Optimization screen anymore on the first boot.
That's because Google has delayed it, and it triggers only in specific conditions : When the device is idle, fully charged, and still plugged in.
This optimzation allows to build the ART cache, which speeds up the system and apps, saving CPU power because it avoids using the JIT (Just In Time) compiler, thus, saving battery juice.
This also means wiping cache isn't going to help with your battery life, quite the opposite.
You'll see he made a test with other users, and the results are quite clear.
Here is a link to the post with detailled explaination and testing, thanks a lot to anupritaisno1 for all this info :
https://forums.oneplus.com/threads/...-and-battery-calibration-myths-busted.993896/

If the phone is OFF it can't trigger the optimization task, this won't be beneficial.
In the article he actually made a test about this, you should read it !
Interesting, but... who claimed that clearing the cache helps with the *battery*?
Also, what happened to the old adage "never leave your phone plugged in" because it causes battery wear?

A lot of people claim this, that you should clear the cache after an update, without clear reason why. At least we have a reason not to.
And this old adage is indeed old, like the "Fully discharge it for calibration". We're not in 2002 anymore. Modern technology had the nice idea to remember to stop the charge, and use Lithium batteries haha !
Leaving it plugged at 100% is not causing any wear. The post mentions a response from an electrical engineer, saying the battery is in fact on stand by and the phone is running off the charger only.

That's just one way to read it. Leaving it plugged in does not, indeed, mean that it keeps trying to charge. But once it goes down, it will charge up again. Also, supposedly, the fuller the battery is when charging, the higher the temperature and hence, the wear. Cannot attest to that, that's just how the argument goes.

Yes, but that's irrelevant. Totally different issue, I was not talking about calibration.

Indeed. But from the looks of it, and what i've read in other places, it waits for it to drop a bit. If the battery is not used, it won't fall to 99% in a night, and won't be charged again until you unplug it. Kinda like when your phone is off. It's gonna be a long time before the battery goes down on it's own.
Interesting, gotta try it.
Still, does the <50, >70% not apply in terms of battery wear? I mean, even for straight-forward charges?

I'd say yes, it still applies. It's a different topic ! Everithing said here is related to software and charging control, when this is more related to battery chemistry. But you're right, it's still true.
To sum it up :
- Charging above 70 or 80% and discharging under 30% (Thoses are the values i read about) is indeed not the best thing for your battery health on the long term.
- BUT, the superior battery life your phone will get with these app optimizations easily counter-balances it. If the phones lasts twice longer, it means 2 times less chaging cycles required, when you think about it (Ofc not accurate, but you see what i mean)
Best thing you can do, if you really want to get the best of both worlds, is staying in between those ideal values, and triggering the optimization manually via the Linux Terminal Emulator
Although, i don't think i'm not personally going to bother, i'll just charge my phone, use it, and charge it again in the evening.
Two days after triggering dexopt manually, without flashing or changing anything, using the phone the same way, i went from 16h idle/2h SOT at the end of the day with 50% remaining to 20h idle/2h15 of SOT with 70% remaining, that's quite a drastic improvement.
Ooh can you share more?I tried googling about triggering the optimization but came up empty...
Yes, that's logic in that, if optimization is so dramatic!
PS I meant 80, not 70, just as you mentioned.

Yes, it's hard to get an info about this, wierd.
Run any terminal app on you phone, type "su" to ask for root permission, then enter "cmd package bg-dexopt-job" (without quotes).
It will run for a certain amount of time (between 10mn and more than an hour, depending of the number of apps you have installed).
When you get the shell back (A line appears under the last one to enter another command), it means it's complete.
If you wanna be sure, run it again, it will finish very fast, because the cache will be up to date (It still checks it, so it's not an instant completion).
Do it plugged in the charger, but with like 30% charge, maybe on USB so it doesn't get to 100% too fast, to avoid the awkward situation where it overlaps with the actual automatic background process doing the same thing haha
The phone can heat up a bit because the CPU is working quite a bit.
You can also run the command through an ADB shell on a PC, if you're not rooted.
Or just leave it charging during a night for once, works too
Best way seems to let if charge for the night regularly though (Quote from the OP) :
"I just say overnight because the device being idle is a condition for the optimisation to begin
Also the optimisation is profile guided. If you were to AOT compile your entire base system it would take 4-5 GB off your storage and that is just the base system we haven't even considered the apps you'll install. Since optimisation generates huge optimisation files it is more sensible to only compile what is slow for JIT to do at runtime. This might seem weird but it takes the cache size down to less than 1 GB on most devices
In other words every time you use your phone the runtime sees what is slow and queues it up for optimisation the next time the condition is satisfied"
Wow. This should be pinned somewhere!
I'll do it in the terminal just for fun, but will also leave it (for my first time ever) overnight too.
Thanks, man!

I think everyone should read this yes, even if it's just for the sake of knowing how things really work.
And i can confirm again, my battery life is so much better ...
A few days ago, going to work, listenting to Spotify on my motorcycle for 20mn, and checking my mails for 2m got me to 96% battery.
Yesterday, and today, same routine, an an hour after that i'm still at 100% ... That's very impressive.
Really interesting.
Sadly the command does nothing on my device.

Are you sure ? It doesn't display anything, that's true. But you'll know it's over when the shell returns.
Or you can juste leave your phone plugged for a night or two, same result.
My battery goes from 100% to ~97% within minutes without using it after unplugging the phone from the charger when charging overnight.
Why is that and how can I get rid of it? It occurs since a few days on custom rom as well as on oos now again.
