Xperia Z3 Rooted- Battery Life Only Lasting 1 Day

Poor battery life on a rooted phone
Hi guys, I just bought a z3 from a friend, and I have some battery problem
On 5.1.1, my battery only last for a day, which is under my expectation for the z3. Note that I only use my phone when necessary, location, mobile data, nfc, bluetooth, wifi are always off when I don't need them. I lend my mother's z3v and its battery life was excellent, I compared the 2 phone by watching a youtube clip for 10 minutes, with only wifi on, the z3v only lost 1% battery while my z3 lost 3-4% each time. But according to cnet (sorry I can't post links yet), the z3's battery have a slight edge over the z3v. Why is this happening?
Anyway, I downgrade my z3 to kitkat, rooted it, install setcpu, greenify, wakelocks detector, I also use disable service. Like before, all the phone functions are off when I don't need them, all unnecessary apps are deleted. However, my phone battery is still nowhere near the non-rooted z3v. I have a feeling that the battery drain faster below 85%, when it reached 15%, it loses 1% every 30 seconds. Moreover, the z3v only loses 1% over night (sometimes not at all) in airplane mode, while my z3 loses about 3-4%.
What do you guys think? Is this a problem with the phone's battery? Can my friend damaged the battery in his six months of using?
Sorry if my English is hard to understand, I tried my best to describe the problem

Battery percentage fluctuation

Hi everyone,
So i noticed that sometimes my battery percentage will drop 2% at a time for example, its 80% and then suddenly 78% ?
Also one time it increased 1%, i thought i might be imagining stuff however i verified it in the battery chart ?
That battery drainage seems good and am getting anywhere from 4.5 sot to 6+ sot(if the mra bug doesnt hit which it usually does)
* i noticed that sometimes if i turn off the wifi from the drop down quick shortcut, then i check the wifi from the main settings i will find its still ON ! Again i also verified it will stay on from the battery chart if i dont turn it off manually from the main settings, so beware.
Hopefully sony will do thier homework with android M
As far as I'm aware Battery percentage is a calculation depending on the status of your phone. So it's not 100% accurate and can fluctuate

This happened to me too! I left the battery runs out completely and so far has not happened again! I'm noticing that this android is sucking the battery very fast, as well as in the Z2 and Sony fixed. But I think that Sony will not correct this in order to be out a new android.
my xperia z2 battery percentage is fluctuating from 100% to 39% then again it rises to 70% plz help me out in solving this problem

Battery Issue for Xperia Z5 Dual E6633

Can anyone help me ?
I got Xperia Z5 Dual E6633 a week ago and I have some problems with Battery draining here is the way it`s discharging after I fully charged it.
1-When the device is on Idle mode and im not using it, like over night ( during night to morning ), after ,let`s say 8 hours, the device dropes about 3 percents ( WIFI is OFF, Data network is OFF, Bluetooth is OFF and the Preferred network is set to "GSM Only" )
actually when the battery charge is getting less and less e.g. around 50% the battery draining on Idle mode gets more and more like during 5 hours drops 3 percents or even over night drops 3 to 4 percents.
2-when I play games on Xperia Z5 (e.g. Asphalt 8 Airborne) the device drops 2 percent every 1 minute, Is that normal ???
im running Android 6, Build number 32.1.A.1.185, I had the same problem when i was on 5.1.1
Is there really anything wrong here ?
Thanks.

Sony Xperia 5 battery life

Hello, I have been using Xperia 5 for couple months and the battery life is dreadful. On standby mode overnight it dropped from 64 to 47 percent. It cannot last even trough the day. I keep gps, nfc switched off, light at around 30 percent mark. I have updated from Android 9 to 10 latest update. But no improvement. Any ideas? How is your Xperia 5 battery holding?

For my part, battery life is very good. You may have a rogue app or something...
If you don't find the cause, consider a factory reset via Sony companion.
