I do realize that everyone is probably going nuts playing with their new units and draining the battery life mad but I figured we start a thread to get general battery usage times from owners. We could also come up with a format that's acceptable, I'll start with this but we can change it as we go.

There is a battery saving mode that is included with the phone under Settings.
Because of the Super AMOLED display, darker colors use less power. Therefore:

Here are a couple of things that really helped my battery life:
Turn off TMobile's contact sync
- Menu -> Settings -> Accounts and sync -> uncheck T-Mobile Contacts
Ensure mobile data is not active when connected to WiFi
- Install Llama (https://market.android.com/details?id=com.kebab.Llama&feature=search_result) and launch it
- Add an event called WiFi
-- Add condition: WiFi Connected (any network)
-- Add action: WiFi Sleep Policy (never sleep)
-- Add action: Toggle Mobile Data (off)
- Add another event called WiFi Disconnected
-- Add condition: WiFi Disconnected (any network)
-- Add action: WiFi Sleep Policy (sleeps when screen turns off)

try SETCPU since you are rooted
make a profile for screenoff (i use 594-128)
that way when your phone sleeps the processor slows way down and doesnt use the battery as much
also if you meant when you sleep.....whenever you can.....use wi-fi and turn APN data off. That way the phone isnt searching for a cell tower constantly and using battery.
Hope this helps....PM questions

FOR 100% NO DRAIN ISSUE
ralnee said:
Okay.. I finally have some answers. I registered my phone on the Samsung site, and got into a live chat with a rep. I explained to the rep (as best as I could) that the battery usage was not updating once it reached 100%, without a reboot. After going back and forth (did you try A, yes I did, did you try B, yes I did...), she finally gave the the number of their "dedicated Galaxy S phones voice support team at 1-877-EZ2GALAXY (1-877-392-4252)".
I called the dedicated team and was finally told that this is a known HANDSET ISSUE, and to replace the phone.
I'm performing a full backup using Titanium Backup as I type this, then I'm going to do a NANDROID recovery (I think) and then reset the phone to factory settings. Then I'll replace the phone at the tmobile store I purchased it from.

Sure, and actually any battery app widget will show the battery level. The Nexus S stops charging at about 96%, so when you would unlpug the charger after it says 'charged', it immediately drops to 95-96%. I ended up buying a couple extra OEM batteries and a wall charger for them so I could pop in 100% charged batteries. Plus it made it so I never have to waste time charging my phone. When the battery dies, I swap batteries. Since this is the same 'family' of phones, I am real curious if the SGS2 does this also? Someone please confirm. Thanks!

I've read about this too, I thought they adjusted it on the software side though (so 100% displayed wasn't really 100% but actually more like the 96-97% of the actual charge on the battery, hence the calibration. I might be wrong though.

It does charge to a full 100% and gives that familiar notification that the battery is fully charged and to unplug it. It drops right to 98% after a few minutes though. Haven't really paid much attention to it just this once.

I can confirm that I have seen this as well.
Can someone pull their battery cover and post the OEM battery p/n? If I get this phone, I will most definitely order some extra batteries and a wall charger. I get 2-4hrs more battery life in my Nexus S charging them to a full 100% in the wall charger and will likely have similar results with this phone. Thanks

Hi can anybody help on calibirating battery on miracle v4 rom
no....nothing can be done
Sent from my GT-S5830 using xda premium
Do bump charging instead of battery calibration. Search it on google.
-Charge your phone to 100%
-Use this battery Calibration app:
https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=de
This app needs root
-Then let your phone discharge until it turns off itself
Notice: in this time you're not allowed to plug the phone to the pc or to the charger again until it turns off
-after it turns off plug the phone to the charger and let it charge without breaks to 100%
-Done
I recall that battery calibration was bogus, there was a post which explained why it was bogus in detail. In other words, don't bother, but charge your battery around 50% if you want a healthy battery.

http://bit.ly/KZdfJJ - Why cant you just google it like he said?
also you can go to recovery and select wipe batterystats.bin
Calibrating your battery does not give you extra battery life, just improves the battery level indicator. Android calibrates battery itself anyway (when battery info change to a few seconds)
batter calibration is of no use i have tested it many times on many roms. our ace has not a good battery. so follow common steps like brightness to 0, application background off etc etc.

thnx will do as u suggested
There is a way to get good battery life in miracle v4 but it took me about 5 days now I get 16 hours off battery with heavy use and about 22 hours for normal use
How I did this
1.let your battery totally die
2.leave your phone off and give full charge
3.still with your charger pluged in boot to cwm recovery
4.now select advanced then wipe battery status
5.now still with with charger pluged in reboot you phone
6.when your phone is fully booted remove charger(you will notice the battery will drop to about 86% in about 10 mins the first time but will get better each time you repeat all these step)
NOTE:I have done this on my wife's s.g.ace with rom miracle v4
And on my Sony Ericsson x8 with many different Rom's
And on my friends Sony Ericsson x10i with many different rom's
YOU MUST USE MAINS CHARGER NOT USB FROM P.C OR LAPTOP AS USB WILL ONLY TRICKLE CHARGE.
If this helped hit the thanks button

according to the miracle v4 developers the battery indicator doesn't indicate about the battery properly ...will charge now to the max even after 100 % and will let you know what happens
I know battery calibration is useless, but how can ace have better accurate reading. And my problem is that whenever my phone deep sleep for a while and i start to use, the battery decrease rapidly after screen in for a while. Its like the battery is leaking even in deep sleep. Is this a common problem for ace user?

Calibration does not improve or increase battery life. It would just help in getting a more accurate battery level reading. Or so i read somewhere.

What ROM are you using? Maybe the ROM who are using still has bugs that disabled CPU deep-sleep. Flash the custom ROM again or find another one to use.

Mate. Non-stop charging your battery doesn't kill your battery too much. It have extremely slight effect because smartphones can stop the charges from coming in when its full. Unless you charge it for like 2 straight days, then it might matter a bit. Or excessly game when you charge and the temperature goes up too high for too long.
And most importantly, The battery getting fat DOES NOT make the phone heavier.

BTW my battery gets fatter. what does it means? ( i notice when i pull out the battery and put it back again. coz it wont fit on my phone... by the way.
should i always charge my battery up to 99% so it wont have extremely slight effect ? and also. should i buy new battery ?? i hope there is some 2900 mah xD i saw one but it feels not durable...

i think,,
never let your battery got fully drained before charging,,,
and let it leave for a while while its not yet fully charged
Here are some fast charging tips and tricks that actually work :
1- Turn on your airplane mode.
2- If you are waiting for any important calls or messages then ignore step one and simply turn off any unused feature like wifi and bluetooth.
3-Atleast once in a month charge your mobile from 20% to 100% this enchances battery life.
4- Atleast once in a week restart your mobile or switchoff the phone for 5 mins remove battery and reinstall and reboot.
5-The most effective is that buy a charger of a mobile like note 3 coz it charges faster than normal grand 2 charger(use at your own risk)
6- If you feel your mobile is getting hotter while charging turn off power saving mode if issue still remains turn off the phone.
Why use another charger? Using another charger than that specially designed for the phone may apply different voltage/current intensity to the battery, and thus affecting its efficiency...
You shouldn't be using another battery, every phone has its own battery charger, it's not a battery cell!!
I'm using a note 3 charger for my grand 2 for about 7 months and well it haven't affected my battery or phone and I bought it from a Samsung store and that person said it won't affect the battery but only charge it fast
"charge it fast" means going abnormal... Nothing's called charge fast and drain the same, if you charge your battery faster than it's intended to be, it'll cause trouble, most probably draining fast or the reactants of the battery wearing out fast, and 7 months are nothing lol!

4Gb for me yes
Bad battery draining on my 4GB too. Asus needs to fix this and update to Android 5.1 quickly. It's bad for a phone to get a bad battery reputation on launch....it may never recover its image unless a fix is released quickly.
I have the same issue
Hi,
I have the same issue, it was charging in fast charging mode for first 2 days now it is taking hours to charge fully
Bear in mind that the fast charger will only kick in when battery is below 68% charged, and I thinks slows down when charge gets up to that amount too. At least that's my understanding of it.
It's only logical I think that the 4GB version has higher battery usage. Android loves to fill up the RAM unlike Windows (which loves to free us the RAM). So maintaining more cache would definitely require more RAM. I made the mistake of buying the 4GB. I hope the battery optimisations in 5.1 will help reduce the issue.

It's only logical I think that the 4GB version has higher battery usage. Android loves to fill up the RAM unlike Windows (which loves to free us the RAM). So maintaining more cache would definitely require more RAM. I made the mistake of buying the 4GB. I hope the battery optimisations in 5.1 will help reduce the issue.

i suspect the issue with the 4GB ram model is the higher boost clock of the processor (more voltage and battery drain)..
if anything, the ram should be helping to keep power consumption in check since you dont need to keep reloading apps over and over.. unless of course theres a misbehaving app
try the usual tweaks such as "disable wifi scanning even when off" and the startup manager.. should help with you mileage somewhat.
if you're willing to root, you can freeze/uninstall many asus apps like dr safety as well

Oh im all rooted and greenified. But yes the higher clock speed can definitely be a culprit. And yes as you say.. RAM should help. But coupled with the known memory leaks of lollipop and stuff, I think the RAM might also to be blamed. Anyway waiting for a sfotware fix soon.
Do you guys have latest software? I think I just got an update a day or two ago, version 2.17.40.6 for my phone. I'm finally starting to see reasonable battery drain now. 12 hours, with screen active 5 hours during that time.
Also disable lots of useless apps from starting with Auto-Start Manager.
What are the top 5 draining apps?

Hi, just got the asus zenfone2 2gb a couple of days ago, and I have the same problem. Charging takes 8 hours at least for a full charge and battery drains from 100 to 20 in only a couple of hours. When I bought it, the problem was already there at the first boot. It took at least 20 minutes to get it from dead to have it finally go on. I took the phone from the box and it was dead. I don't know about asus, but I am sure that every phone that I have ever bought had at least a little bit of power when first taken out of box, but this phone was different. Was it a factory defect or am I just charging wrong?

Make sure the cable is inserted in the charger all the way. Or try another charger or cable.

Ha ha ha my 10/2/15 post...
... updated info...
yes, 4gb version. 64GB ram (32 GB memory card)
yes, even did (I bet this screwed it up worse) an update earlier this week.
before that I was able to get device booted or at least saw a cable.
I have tried at least 6 different USB micro charging cables, and several power sources..
(portable battery, direct ac power, ASUS supplied charger, and 3-4 other chargers (cube/hi power, etc)
...STILL wont get power..
yeah right.
I) I hate the non-removable battery.
2) device (in past) has just dropped dead, and t00k 3-5 hrs before it had a charge sufficient to boot phone
3) upgraded OTA updates, last one early this week.
3) current status:
Phone dead, wont charge:
(have a usb cable that turns from blue (nothing attached or full
battery) to Red (connected or charging)
it is solid blue...
also tried the charger that came with device, as well as a hardwired ac (USA) charger, and some fast chargers I have (4a/5v)
The blue light on the USB cable is telling me that:
* the cable is getting power from the source
* The device is not recognizing the cable or power source .
ALL in all, I liked this device (except for battery), and now I am frustrated
I figured out that the fast charge didn't work when any power saver was on. Just put it on normal and then try. That should solve the problem.
in stock rom there are so many bugs so u guys who still didn't try custom roms, try that and it will help to extend battery life and performance also

Don't forget to switch of all Google apps , in Lollipop Google is a battery killer.
And, this helped me, read the faq's in Asus Support on you're phone.
I bought this phone for the increased battery life (3000mAh and Asus claims over 12hrs battery life) compared with my Zenfone 5.
Very disappointing so far.
After tuning the apps the battery lives for 10hrs but only in standby. In case of gaming or making phone calls the battery life is horrible.

The "3000mAh" don't really means something, because each phone consumes more or less power. And what Asus claims is claimed by Asus, the manufacturer so it might be faked a bit.
