[Q] Battery less than 2600 mAh - Xperia Z3 Compact Q&A, Help & Troubleshooting

Hi, I recently got a Z3 compact from clove uk. And I haven't seen the 6+ hours of screen on times that other people are reporting. I've had Battery Monitoring Widget on the the phone since the beginning, and while the system files say the battery has 2663mAh of capacity, the app only records me using up to 2300mAh of battery from full to dead.
I'm not worried about the perceived runtimes as I'm in a bad cell service area and I still have the new phone syndrome. But the physical capacity of the battery seems to be lower than stated on my device. Does anyone else use the battery monitoring widget and can report their numbers?

If you goto the compare tab of Battery Monitoring widget, what's the measured capacity of your battery?

Right now it shows "0" but I will charge it right now and tell you. I have only just installed the app. No measurement yet.

Thanks for checking, for more accurate results, it's best if you could run the phone from 100% to dead once or twice, so the monitor can capture the full range of your battery.

It will take some time though. That battery just won't die :laugh:

To whatever extent you have "new cell syndrome", it's gonna appear as reduced capacity.

First result at +-27% accuracy: 2280 mAh
Charging cycles: 2

If you can get a number with accuracy below 10%, that would be best, cause batteries are usually manufactured to 10% capacity accuracy.
Thank you

Allright - just don't expect to see the final results within the next few hours

It now says:
+-12% accuracy and still 2280mAh
After unplugging the charger it's: 2253mAh

The value went up to 2398mAh. Accuracy is still at +-12%.

Ok, thanks
Mime says 2440mAh with accuracy at +-5%.
What kind of screen on time are you seeing?

If I remember correctly I had a maximum of ~7 hrs screentime. I did some benchmarking and stuff like that so I'm pretty satisfied with battery life.

[Q] Charging the battery

hi!
i have a question regarding charing the battery. let's say the xperia z has something like 63% battery left. and i put it on the dock and let it charge up to 100% (or even less, e.g. 90%). and i do this quite often, will it some kind of "damage" or harm the battery, so that the battery life will decrease?
i mean the battery life doesn't seem to be that good, so i plan when coming home to put it on the dock, whether the battery is empty or not. and then when not used, leaving the phone on the doc.
thanks for your help & have a nice day

That was the case with old-style Nickel-Cadmium batteries, but no phone has used those in a long time. With modern Lithium-based batteries, regularly charging shouldn't be an issue.

so i can charge it as often and as long as i want, independent from its actual battery status? it won't lose power after time? even if i charge just from 70% to 75%?

It definitely will, my iPod is discharging quicker (at least it seems so) than a year ago when I bought it, and my current phone's battery (8 year old) can last like 20 minutes of talk time

It will lose power after time - all batteries do. You can charge it as long and as often as you want, it doesn't matter. If the battery loses its capacity - remember that Sony covered it under 24 months warranty and you'll get it replaced it its maximum capacity falls down under ~75% of its original capacity.

Do they test it somehow or can I just go to Sony service center every 11 months and get a new battery?

There are free apps on the market that can assess your battery capacity. Of course if you're going to claim warranty - Sony will check it with more accurate methods, but even those free apps can measue your batterys's health quite accurately.
I'm not sure about the 75% number. Might be lower, might be higher. Usually it's set at 80% but i'd have to check that in the warranty itself ( will update the number when i get home )

LG G4 Battery Guide

READ THIS BEFORE READING FURTHER: THE NUMBERS LISTED AFTER THE BATTERIES ARE EBAY LISTING NUMBERS, JUST TYPE THE NUMBERS INTO THE EBAY SEARCH BOX TO FIND THE BATTERIES
-HOW TO TEST SCREEN ON TIME (SoT)- (Note that I do not recommend any type of battery waster app, they get your phone way to hot)
**Feel free to contribute to this post. Screen On Time's are done by taxing your phone for hours on end, examples of this are watching youtube videos nonstop, watching movies, surfing the internet, ect.. I personally run youtube videos by "Ollie Duracell" that are an hour long each, fullscreened with an actual video not a picture(you dont want display burn in), one after the other at full volume. Brightness at 60%, I use lower 60% brightness just so my phone doesn't get hot. I turn GPS on at max(high accuracy setting), just so I have more battery drain. And I use WiFi instead of the 4glte for data. **
-BATTERY LIFE CONSERVATION-
To save battery life after testing your battery, you could simply lower brightness even more(i actually leave it at 60%), and disable GPS(disabling GPS will get you at least an hour more on battery life). Oh and one more note, I charge my original battery and extended batteries normally while still in the phone. There are theories that you have to use an external charger to get 100% battery life, but I do not believe that to be true. I can get 5hrs screen on time out of the original LG battery when turning off GPS. Also, LG original battery is not good quality, if you do the math, these batteries out perform it comparing MAH to MAH.
-BATTERIES-
-Stock Size- (These are the same size as the original battery, they will fit with no extra bulk)

Thanks for this Guide and for including me in it. The sad thing is I don't get good signal here so only WiFi. I'm sure someone could calculate my runs with LTE use
Edit: the TQTHL brand is good. They have remade there branding colors to a more darker Blue than the old light blue color (post a pic in a bit)

How is the TQTHL battery performing over time? Does it still retain its original capacity?
Because my chinese 4000mah battery used to work great for couple days and then started losing capacity to the point where after little more than 1 month it's useless
Well my 4500 still works but I'll need at least 5 more runs with the 5000

Edit: Just so you know I'm back on 5.1 cause during my time on 6.0.1 i found that my Batteries no longer worked correctly but on 5.1 they work fine again. Now idk if it' MM or a bug in my motherboard (which i doubt cause i changed my phone once) or a bug within MM
Newb question, but do you need to be rooted to calibrate the battery with a different mah than the stock size? Or will draining it and recharging it a few times work just as well? Thanks!

Yeah I think the OS has the mah locked @3000 cause I need to use the battery widget to edit the mah but no root is required. The wedgit is on my thread first post
Just so you know it don't actually edit the mah in the OS Kernel just the App
Here's my 4500mah. Now below it all depends on what you do but for me I don't game at all. Just YouTube and site seeing

Is the OS properly reading battery capacity or is it stuck at 3000mAh? I mean, going from 100% to 14% did you consume 3870mAh (out of 4500) or 2580mAh so you still have almost 2000 available?
Thanks in advance
Nope it's locked @3000 and yes I'd say so. I'm on my 8200mah right now. Some pics later on for battery consumption

Just to be clear: you think you used only 2580mAh (86% of 3000) so you still have 2000 left even if it says 14%?

No No I think I had maybe 1500mah left or something similar to that
It would be interesting if we could set the battery capacity to 4500mAh with root... Do you know if it's possible?
So far they are saying its not possible. You have to change a kernal in the programming code to change the MAH capacity, and no one can find out on how to do it. Someone was trying to get in touch with a coder from LG but so far its a no go as I understand.
Yeah I'd say give up on that and just use the battery widget app

umm I actually don't know really. I just edit the mah and go from there
Just bought a export h815 set. The battery isnt impressive at all. Didnt manage to get even 3hours SOT. Even flash from mm to lolipop and didnt see much improvement. Is it hardware issue with the phone itself or just the battery. ( change the battery and see slight improvement).
It's mainly due to high screen resolution and the cpu/gpu. Just saying a guy who don't game at all and especially the high resolution on a 5.7 inch screen? Come on 720p is all we really need. I don't game so can't say on that behalf

your actual battery capacity in 3t

Can you guys download accubattery and check your estimated capacity against design capacity and thus you battery health.
Please attach details of your ROM and the age of your phone.

3277 mah, beta 9 (stock), bought around Xmas time. Not sure if the mah will change if app is installed for a while and it sees several cycles.
It showed 3250 on new phone

Actually it just compares the percent charged to the change in mAh so it isn't some weird bs like "deleting batterstats.bin will increase battery life". This reading is also shown in settings in MacBooks.
Mine was at 94% estimated capacity the first day i got the phone at its release. Now, it shows 92%.

Short term AccuBattery use is not an accurate measurement of battery capacity. You need at least a month worth of charge logs to get anywhere near an accurate reading from AccuBattery.
I just charged my Rog Phone 2 (received it 3 days ago) from 0% to 100% with a USB Power Meter inline on the charging cable (which is the best and most accurate method of testing battery capacity), and it took exactly 6,105mAh to fill the battery.

I have done but only with the phone turned off to get a more accurate figure. I don't think it's that important for AB, especially considering my results are almost identical to what other users have reported.
I see people in this thread using USB power meters, saying things like "it took exactly 6,105mAh to fill the battery" but there are no maths explaining how they got to this figure. You can't just take the reading from the USB power meter as that is charging at 5V or 9V which is different to how the batteries capacity is rated. Ideally we should be using mWh as it makes these things easier.
When I charged mine 0 - 100% with the device off, I got 27.4Wh from the power meter, the battery is rated at 23.1Wh so taking a guess at 15% for efficiency losses and you get 23.4Wh charged.

Estimated capacity is going down pretty fast.. (was around 5600mah when I got the phone) Also measuring only around 5080mah with a USB-meter.. The battery-% on this phone is very unstable. Anyone else with the same experience?

Is there a way to verify battery capacity to verify battery replacement?

With the announcement of the 1-year extended warranty, I went to go replace my battery today at ubreakifix. When I picked it up, the employee gave me the feeling they didn't actually work on my phone but billed Google for the work. Besides the fact that the things he said made me feel like they didn't actually work on it, I noticed when I picked it up the battery was within a few % of when I dropped it off. I'm trying to see if there's a way to check capacity or anything of that sort I can do to verify that my battery was or was not actually replaced.
I appreciate any help.
Your SOT should noticably longer.
New batteries typically have around a 50% charge on them.

It was around 47% when I picked it up but I dropped it off at 53% which I thought was odd. That's good to know the range is correct for a new battery though. The guy was sketchy and made several comments that made me think he didn't actually touch it. I was hoping to check capacity or something to verify the change but I'll use it tomorrow and see how the battery life compares. If I'm still having battery issues, I just wanted to have concrete proof if I went back. He made a point to say "if it's still acting up then you'll just have to call Google and have the device replaced instead".

You can use AccuBattery to check estimated battery capacity. You'll have to go through a few charge cycles to get an accurate estimation.

It's total battery capacity estimates are not accurate. If you had been using it before it's SOT/% history would be useful.
I use it track my battery usage % vs SOT to spot misbehavior.
It's charging time/% history is also useful for monitoring charging. Erratic fast charging is one of the signs of a battery failure.

It's history is but the actual mAh measurement isn't.
With no calibrated reference of the voltage to mAh ratio it can only do so much. I believe it's measuring voltage drop and calculating current and mAh from that instead of voltage×current.
Whatever the reason(s) it's absolute battery capacity isn't accurate.
I maybe mistaken but even though some power controller chips have current sensing capabilities, Android doesn't use that readout or make it available to any apks.
An Android shortcoming.
A Developer here maybe could or has shed light on this before.
Edit: some brands/models can apparently:

No information on Samsung models that I could easily find.

Like I said, I have found it accurate enough in my experience. New phone is around 100% estimated capacity. Year later, 90% or so. Year later 85% or so. Done this with several phones.
Not here to debate or argue about it. If the OP doesn't want to use it, they don't have to.

That 10% is from the original OEM battery and the replacement. Android it's self lists it at 4100 when it should be 4300 new. Accubattery uses the Android figure unless you change that value.
He'll get a good enough idea if the phone last longer during usage. It should be a noticable improvement... and I hope it is.

The battery capacity for this phone is 3,700. Like I said, I'm not here to argue or debate it. You do what you want and the OP will do what they want. So please stop quoting me. Let it go...

Just reporting back that it was definitely changed. I charged it before bed and decided not to put it in the charger over night to see what happened. I woke up and it was still at 99%.
It's been off the charger since 11pm yesterday, it's 8pm now and I still have 16%.

Good deal
Guess the tech just has a guilty face

Another way to check is with this online tool https://bathist.ef.lc/ Battery Historian. Make sure to charge your phone to full keep on the charger for a bit longer even after 100% If you can do it with the phone powered off that's even better. Turn the device back on take a bug report and upload it to the site. Then look for the "Coulomb charge" value and mouse over it. It will show you how much the device charged in Mah say for example you see 3650 then you divide it by the battery capacity for our device which is 3700. This means your battery health/capacity would be about 98.6%.

Assuming that phone has accurate current sensing hardware and it's readout is available. All Androids report voltage relatively accurately... current not as much so.
