power problems - ZenFone 2 Q&A, Help & Troubleshooting

My phone is suggenly shutting off when the battery hits around 50%. It's also a sudden shut down not a usual "your phone is shutting down" type thing. But I dont think it's the battery because when I plug it in to charge the battery icon shows it to be half full already. Since it's such a quick power off I doubt there would be anything in any logs, But where would I look log wise just in case? Anyone have any experience with this?

4. while open the cover, usually have to press the power button it's only wakeup, but this time its on every moment..
Tried solution :-
Problems occured while using gprs for internet, it hang so soft reset it... after soft reset everything is fine, but the battery drain out so fast... and the device is WARM...
Flashed back to original rom (o2) - still the same
Tried flashed to WM6 - still the same problem
i got 2 x batteries... the problem still the same (not the battery problem)
anyone can help out with this?
thank you so much
try using 2А battery charger .. I have had similar problems that I decided to convert the old computer power supply for charging purposes
I was going to say your battert's old and dead, but since you said it was independent from the battery, now I think the drain and the heating might be explained by a short circuit somewhere in the non-vital parts of the device, or a malfunction of the power control circuit, causing constant drain and heating up the battery.
As for the device beng constantly on, have you checked the power settings? If those are all right, they can stil be attributed to the faulty power controller...
I suggest you take it to a repair shop(since your ROM-flashing probably voided the warranty, so the provider will just turn you away...), they might be able to do something with it.
I suggest you check back later to see if someone more knowledgeable than me offered confirmation or another opinion...
Good Luck!
theres only one thing i can think of: Turn off your wifi when you dont use it Xp Thats the only reason i can think of when your device gets warm and the battery quickly drained ; D

I don't think so...the wifi doesn't use nearly enough power to heat up the device or drain the battery that quickly. Even with all wireless options enabled, but screen brightness set to minimum, the battery lasts approximately one and a half hours for me.
I think the quick drain and heating is caused by either a non-critical short-circuit or a faulty power controller circuit...
maybe you gor ripped off. what kind of battery did you buy?
The battery that im bought recently
same as the old one.
PU16A Li-ion Polymer Battery 1620mAh
everything i tried to save the power
everything off except the phone, the backlight set to the lowest.
im charge it with my charger instead of USB port from computer

[Q] Instant discharge.

So, I'm on my Evo today, playing a game (Air Strike). My battery is at 93% when I picked the phone up to play, and the phone is plugged in. Suddenly, with no warning what-so-ever, my phone shuts off. Of course a mini-freak out and many "wtf's" ensue. No warning, no signs, even the led went off. I pulled the battery, put it back, then plugged the phone in again. After that it gave me the blinking light indicating the battery was too low to turn on. After a few minutes charging she came back on and battery was at 5%.
How the hell does a battery go from 93% to 0% in less than 5 minutes, and give no warning at all?? Anybody else ever have this problem?
Wow I've have never heard or that happening before. Maybe a glitch in the battery stash? Did it take awhile to charge up to 100%? Can you reproduce the issue again?
Sent from my EVO (CM 6.1.1) using XDA App
I had this problem with my older phone once. The battery itself may have a problem or your phone is not getting charged properly.
Try These :
1) Try charging the phone overnite from the Wall charger (Not through USB of your computer)
2) If the above does not work, and you have access to another evo battery, then try using that.(try using a friends battery and charger for a day. ) (Ofcourse needless to say the charger and battery must be for Evoonly )
In my case, my phone started working fine again after getting my battery & charger replaced.
Probably shouldn't worry about it too much just yet. Could be something as simple as your battery meter was mis-calibrated. The meter itself is software so it can easily be wrong/off. If it continues you may have a bad battery.
Sounds to me like something is wrong. Did you just get the phone or have you had it?
Idk... The phone had been plugged in for most of the day (hadn't gone anywhere. Lazy day lol) And like I said, the led went completely out as well.
Haven't had the problem again, so we'll see I guess....

I've seen some posts about the Evo battery shutting off the charge when its being used. Were you using your Evo while it was charging?
If the battery doesn't seem to be giving you percentages that are accurate, you might want to recalibrate your battery.
Common misconceptions sticky (Evo Q&A) said:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

[Q] about my battery

ok so i got a problem with my battery
my battery on my phone just going out to fast
for example today
i connected it so it could reload and then
when i disconnected it was 100%
then after 2 hours only that i havnt use the phone i mean havnt touched it even once
i look again on battery life and here it says 36%
and it keep going every day
can some1 tell me why it keep happening???
WOW! That's a major drain in 2hours.
My 2 cents are on a defective battery - since the phone was on standby.
You can try some tutorials on adjusting the power saving settings (like screen brithgness what to turn off and not etc.)
Also you might try caibrate the battery.
there is a thing like u charge it to 100% ,unplug from the charger and turn the phone off ,then plug in again and charge to 100% again... there is a thread about it on this forum, do a lil search it might help u
Dial *#*#4636#*#* and go to battery and find partial wake usage, here the apps are listed that prevent the phone form sleeping and thus causing battery drain. Also check the % under Settings-about phone- battery usage to see what app or process consumed the most battery.
Does it get very hot? I mean - if the battery really contains 1500mAh (which I doubt in this case) and drains completely in 3 hours, that's 500mAh, so 3.5V*0,5A=1,75W continuesly.
You really should notice that while it's in your pocket...
no the phone isnt getting hot
i mean it can sit on my pocket for like 2-3 hours and then it suddenly 3x %
without even touching it
Try these steps:
1. Please connect the phone to the charger with the phone powered on, and allow the phone to charge until the notification LED is green, indicating the device is fully charged.
2. Disconnect the phone from the charger, and power it off.
3. Reconnect the phone to the charger with the phone powered off, and allow the phone to charge until the notification LED is green.
4. Disconnect the phone from the charger and power it on. Once the phone is powered completely on, power it off again and reconnect it to the charger until the notification LED is green.
5. Disconnect the phone, power it on (OPTIONAL: Enter Recovery at this point and Wipe Battery Stats (from Advanced menu), and use it. You need to use this sequence only once.
If that does not solve it you have a defective batterie.
ok i will try it
but can u tell me what the point???
i mean what does it do??

The point of that, is to make the battery life longer. And actually it works. I tried when i bought my phone an the increase was significant!
Edit: Just saw in another thread that some newer custom ROMs has some things messed up, and they eat the battery more than normal when the screen is off. You might take a look at it.
yea i did all the steps and its not working
the battery still going down rapidly
so i should buy new one??
Yeah.
BTW, are you on a stock rom?
srry
no idea what stock rom means
but im on miui rom

[Q] Phone shuts off before battery is depleated even after calibration

OK so here is the deal.
I did the battery calibration of charging to 100 and then wipe the battery stats and then fully deplete. The following day I wanted to drain it even further down so after the phone hit zero and shut down. I then plugged it into a usb just long enough to get into recovery and then immediately unplugged it from the usb (10-15 seconds.) I just left it sitting there in recovery for AN HOUR before it shut off on it's own. I am wondering why there is that much power still left in the batteries and yet the phone still shuts down? Is there a reason the phone needs to keep that much of a reserve?
Thanks!

Well, draining a modern lithium ion battery completely is detrimental to it's lifespan, so... yes, there is a reason for the reserve.

P8000- Battery drain while phone is off.

Hello,
I received my gold p8000 three days ago. I noticed something very strange. The Battery drains when the phone is powered off.
If I fully charge my battery and then I turn the phone off (not standby, power off!), the battery drains overnight and the next morning I cannot power on the phone, I have to plug the adapter and wait ten minutes before the phone accepts to boot
I'm on stock rom 20150815 unrooted but it happens also on 20150725.
Did anyone also notice that?
No, that is strange. Is your phone getting hot while it's off. Sounds like it is not really "off"...
Sorry for the late reply, I've been very busy.
I've experimented about my issue and I found the cause. The phone was in fact very hot. It seems that the place where I hold my phone was too small and the power button was pressed down. It seems that pressing that button drains the battery pretty fast.
Thanks a lot.
