[Q] Sony Xperia SP battery drained 1% per second?

During the night, my Sony Xperia SP was charging. I began charging at 1:30am and i fell asleep after that. I woke up at around 8:20am and pressed the power button to turn on the screen. It did not turn on, and then i noticed the phone was turned off. I powered it on and the battery was at 100%, however i thought it was strange that the phone was turned off because i had left it on overnight. I checked my battery stats on Battery Widget Reborn (The Android battery stats, GSam and Better battery stats showed no data because it was all erased as the phone turned off) and found out that my phone had completely, after being fully charged, drained 100% of battery in just a few minutes. This is the first time it had happened, and i had bought this phone only about 2 months ago. I had not left any processes/apps running, even so, the battery should not have been draining this quickly. The drain from 100% happened from about 4:18am until 4:20am.
What would have been the cause of this battery drain?
Has this ever happened to your phone, and is this problem unique to Sony Xperia phones? I have heard that Sony phones have very bad battery optimisation and battery life.

First of all, sony phones have great battery lifes. I know that because of my experience with xperia phones (mine and friends' ones, too). Personally, I passed through an xperia tipo and now I have an sp, so they DO have great battery lifes. As for your problem, I think it's the battery stats that cause it. If you'd be able to take off the battery (youtube might have such tutorials) for at least 10-15 seconds and put it back on, it may solve the problem (taking off the battery for such a time is similar to "wipe battery stats" command in recoveries). Alternatively, you can install a recovery (e.g. c.w.m.) and wipe the battery stats. If the battery keeps draining like crazy, I'm afraid it's time you went your phone to a service center so they'll replace it with a new one.

Huge problems with my galaxy s3 in the past few days.

Hello everyone!
This is my second post here...but I really felt like I had to take attitude this time and actually do something.
So my samsung galaxy s3 is acting so weird that I can't use it without something bad happening for one day.
So...first of all...my battery doesn't last more than four hours straight if, for example, I am listening to music.
It literally goes down about 1% every few minutes.
Also..there is something really weird happening with my battery even after it completely shuts down. Lets's say I am on 1% and the phone shuts off. After the screen goes black and I plug it in...the charging screen appears and the battery seems to be half charged. I open the phone again and it is already at 45%. All this operation takes a matter of seconds...but still it goes from 1% to 45%. After the phone is up...this percentage starts to go down even faster than before...in the end my phone shuts down again...and this time it starts to charge from 0%.
Today it shut off...and when I got home and plugged in the charger it didn't do anything...i just left it like that for about 10 minutes then tried to power it on without the charger being plugged in...and it worked. After that it started to charge. I have no ideea what is happening.
Also...my charging time is really big. I do not know why but when I use another charger from a samsung galaxy mini 2 it seems to charge way faster.
That's pretty much all so far. If you need more details, please let me know.
I hope you can help me sort this out!
Best regards!

1.Might be the battery is dead or broken, or its not calibrated. How old is the phone and battery?
2. It seems to take ages to charge my s3 lte too, give us a number in hours how much time you need?
3. The problem where phone wont turn on or show charging when battery is as low as 1%, i had this too, i think its normal, its protecting the battery
4. Do you have overcloacked anything? It happend to me when i had ovecloaced and did benchamark test, the phone froze and battery eas 5% when i restarted the phone, but before it was 45.
Not realy helpful but i am trying XD. Also might wanna buy new battery, its not that expesive

if you are running stock rom with no rooting no anything....100% it's the battery.
if not install stock and see how it goes...if it's acting normal then the mods are the problem...if it's the same it's the battery.

Do a factory data reset on stock recovery. See how that works out first

Starting from factory reset is bad idea - it should be the last step IMHO.
First what in such case we need to check is battery health.
Percentage we see on our phone is weak indicator, because it is calculated
Better to see the voltage in different situations. How to check this (terminal app or adb in console):
cat /sys/class/power_supply/battery/voltage_now
The lowest voltage that device can handle without heavy usage is less than 3500mV (I saw even 3240mV, but with low brightness, no data connection and after trying to make a call phone turned off).
The maximum voltage is obout 4300mV.
When You see 1% of battery and voltage is realy close to 3500mV or battery is charged and voltage after removing charge is dropping realy fast to then your battery very likely need to be replaced.
I bought Samsung Extended Battery (3000mAh) and this tripled the time usage than my 2 years old normal battery 2100mAh. You can see that difference in their capacity is much smaller - about 43% biger, but give me 300% much time on battery so old one was realy worn out.
BUT if your battery wasnt used for longer than half year, you can do as follows:
1. Discharge battery
2. When phone turns off - turn it on again, but into download mode (Home-VolumeDown-Power)
3. Leave phone for as long as it turns off again and repeat step 2 till time that Download Mode wont even boot.
4. Take off battery and place it back, and again try point 2 (start Download Mode) - do it until phone will show Download Mode for only 2-3 secconds
5. Again and last time replace battery and charge phone, but turned off
6. When phone will be charged, turn it on and leave it on charger for about one hour
After those steps use your phone lightly and try to repeat whole process one more time but only when the battery will normaly discharge and phone will turn off.
I tried those steps and battery for sure can work longer FOR ONE RUN, but unfortunately it can lead to loss of capacity much faster, but it will be noticable after one year - IMHO its always good time to buy new battery.

Nothing good will come from that procedure. Those steps were useful in the epoch of nickel-cadmium batteries, where the battery had no internal circuits to monitor itself and had a tendecy to uncalibrate. Those stops would force the device and the battery to re-adapt to one another.
But now we're using Li-Ion batteries, and those DO NOT like to be fully discharged. Hell, the device might not even recognize the battery, if it has really been fully discharged.

Okay...so I went to the shop from where I bought my s3 (Orange shop) And they told me to send it to their service and I did so...as I still had it under warranty. It was there for exactly a week and today I got it back. They told me they replaced the battery (which they actually did...I checked that) and the power connector from my phone. The battery it's still not good enaugh in my opinion. Immediately after I got it back...I turned it on and it had 79% battery. In about an hour it went down about 25% (so to 54%) but I didn't used it havely (note: the mobile data option was on). I really do not know what to do. I asked someone and they told me to send it again because this is not normal.
My s3 is running stock 4.3 and used to last waay longer back in the day.
What should I do? I literally got about max 5 hours of use before I sent it and I am afraid this will happen again. I do not even want to think what is going to happen if I listen to music for example.
I turned the phone off a few hours ago...then let it charge up to 59% and then stopped because I had to leave. I used it moderately for about 4 hours and 51 minutes (as my phone says) and i have about 2h and 15minutes of screen on time. My screen is using 50% of the battery and also Android system is using about 17%...chrome 12% Android OS 7% and I think everything else is less important as they use 7%<. After those almost 5 hours...while the mobile data option was on all the time I am at 14% battery.
What do you think? Is it good enaugh? Should I send it back? I really need help!
I am waiting for suggestions.
Best regards!

I think so, the fact that you have the screen on top of Android OS (and not the other way around) pleases me. You had your screen on for 2h15m, of course your battery went down fast
Test it, charge it full, and use it. Normally.
Do this for 2 or 3 days, and check how the battery lasts

Inaccurate battery %??

After charging my battery fully to 100%, I unplug it from the charger and without even turning the screen on, the battery drains to 92% within one hour. I check the battery stats and there are maybe only a couple wakes during this time.
Sometimes, the battery shows a certain percentage longer than others. Example, my phone will be on 65% longer than it would be on 60%.
Battery still gives me a solid 2 days usage with about 3+ hours screen on time. The service menu also says that the battery is good.
Is there a way to get the battery reading to show more accurately?
Thanks,

Hope I could Help You
For your battery problem, I guess you could try calibrating it. And also try to install "Greenify" along with "Clean Master or 360 Security" and try to close all running apps before turning off the screen. I also turn on Stamina Mode when the battery is at 100%, in an attempt to further save battery life. And the result has been kinda meh, but well, battery drains about 1% per hour. It lasts about a day and half with light usage. In my case, light usage being, browsing, youtube videos for about 2 hours, listening to music, social networking and taking some pictures

Hey,
im using greenify (my phone is rooted). Battery is quite good for me though. I get about 3 days with light usage. I start charging my phone again when the battery gets to anywhere between 10-20%.
I read that maybe its better not to let it get so low?
I have no wake locks either.

Umm.. IMO, 10-20% is okay. I usually charge the phone when the battery gets around 5%. I read somewhere that charging battery too early can affect the battery's overall standby time (reducing it). It's better not to let the battery reach 0% though.
I had that happen with my Samsung Galaxy Note 2 earlier. I once let the battery dip all the way to 0% many times. After a few charge cycles, I found out that the battery was dead and wouldn't charge at all so I ended up buying a new battery :-/
Umm.. Coming back to our Z1's, could you try putting the phone in stamina mode everytime the phone is kept on standby mode? This boosted my battery life a lot I even put my phone on stamina mode throughout the whole night yesterday to test the battery life again, and when I switched on in the morning, I saw that the battery had dipped by just 2% (standby time of 7 hours). I'm really confused how your battery drops so fast, 100% to 92%.
Could you try calibrating the battery and then putting it in Stamina Mode while on Stanby and tell me the results? I hope I could help :fingers-crossed:

Yeah i could try to calibrate it. Im a little confused on what you do to calibrate the battery (ive read way to many opinions on this). Can you please tell me the steps.

battery dead or?

Well bought this phone back in mid 2017,and because of sickness I haven't used it that much at all.
I charged the battery 11 times so far and was keeping the phone in a desk drawer.
A month ago I noticed that the phone won't turn on,so I plug the charger on and charged the battery to 100 %.
I supposed that the phone was on,I didn't turn it off,and the battery left to 0% and shutdown the phone.
I really can't say how long it was on 0% (suppose like maybe a month).
Today I noticed very bad battery results.
Batterylife with GSam Battery Monitor is around 12 h only.
Was the "bolded text" the reason that battery died or the reason was not using the phone for 2 years?
Is there a software to check the damage of the battery?
I installed accubattery pro but for some reason doesn't offer me Health status of battery.

I would give the battery a few full cycles to see it that sorts it or yes, the battery it would seem is on its last legs. I don't know what app to recommend as an alternative though. (My battery is 23 months old and still performs as it did when I brought the phone)

I would drain it to 5% (maybe 1%) then charge it to 100% (without using phone while charging) a few times.
Then see how it goes. Afterwards charge phone from 20% or 15%.

Ok.I will charge it to 100% and report you with results with duration time on battery and you tell me how bad is it

GSam Monitor:
Battery Life: 3d 19.9h (5h 26m active)
Screen On:3h 40m (1h 17m Max)
In Android: battery estimated battery life: 2d 1h

Question Battery drain issue

Hi there, are u guys having battery drain when reach 20%? Like down 1% per second when 20% or lower. I did hard reset but the problem persist.

yes, drains pretty fast even before I could connect to charger it shuts down.
when battery remains around 5 % ,message gets displayed that phone is going to shut down in 30 seconds, like that.
To get automatic call recording I got Indonesian rom flashed in Indian model. I was thinking battery drain might be because of that.
