Disclaimer:

Yesterday I did a lot of calling. About 50% of my usage was calling over WhatsApp and/or regular phone.

I measured the battery life by adding all the bars in the during I was awake.

I unplugged the phone from the charger at 100% around noon or so and my day ended past 2 AM or so. The usage happened in between. Didn’t use low power at all. Every single setting that can be turned on is on indeed. I don’t turn off anytime. Screen time was on too.

Most days my battery life isn’t this good.

Hi guys,

During my work day yesterday, my X went from 100% to 36% with about 6h 45 min usage (that’s a mix of screen usage and WiFi calling, 50% of each). Over say a 13-15+ hrs period.

It was a mix of 4G and WiFi usage. Including times when the phone was using 4G on nearly full or full brightness to times of WiFi and say 25% brightness.

If I had waited to reach 0% I could have easily got a standby of 24-32+ hrs with 9-10+ hrs of real usage.

This is pretty good indeed. What do you think?

Calling, in my experience, is neutral on battery. Not draining, and not like music, which doesn't drain anything. Just neutral. That was nice battery life!
Now, a little curious thing that's unrelated: I picked up a call from my iPad with the feature to pickup from a device connected to the same Wi-Fi network, and it killed my battery. It went from 100% to 99% in 22 minutes (generally takes about 55 minutes to drop that first %). I don't know why, and I never use that feature.

On my mi max 2, currently at 45% battery left, 12 days without charging, 5 hours screen on time. :)

Did your iPad’s battery drain or your iPhone’s?

I unplugged my X around 10 AM.

Day ended around 1 AM at night.

Usage approx 6hr 20 mins of which >50-60%+ was actual on screen usage and the rest was calling etc. But probably 4+ hrs was on screen usage.

I was down to 36%. On track to cross 9 hrs. This is comparable to iOS 11 battery life.

Screen time feature was off. Most days my battery life hasn't been this good.

So you got battery replaced? Has it been better since or what you think caused it to improve?

I'm still not quite confident with mine. I exchanged it to new one and while it is better than the first one there is quite a huge difference to our other X from different factory. My second unit (SG) is also from FK factory and it is manufactured 1.5 months later than the first one. Our another is silver and from DN factory manufactured between the mine two, so age difference should not explain anything and it was bought the same time as my first one (just over one month ago).

Here is example from few days back.
With my new unit I got about 3 hours 15 minutes of SOT in 44 hours standby time when battery went from 100% > 38%.
At the same time that another (silver) got about 2 hours and 50 minutes SOT in 80 (!!!) hours standby time when battery went from 100% > 30%.

Both units have screen time feature on, so that should not explain anything.
I don't know what causes the difference but I begin to suspect that hardware components power consumption or batteries are better in this silver one made in different factory.
When I test them by running something same in both units side by side with the same display brightness, battery level goes down about equal percentage in certain time. Also when they are left alone for a night and I check battery level in the morning they have both dropped equal amount. But when those units have some rest and I start to use them, mine seems to drop percentage or even two pretty quickly while that another can go on showing the same percentage from quite some time. :confused:

No. It’s not improved after the swap. Each day is different. 4G/high brightness kill the battery fast.

Both your D perform the same. Longer standby is the cause of your drain.

This is really confusing what causes that. Mine is more or less the same, so I get very inconsistent results day to day. From what factory yours is from (the first two letters in serial number)? Did you check with iMazing what brand battery was replaced in your unit and what it was before replacement (it also show battery manufacturing date)? My both FK's have F8 battery while that strong silver/DN has F5. I'm not sure what that code means exactly but obviously they are from the different battery factory.

Both your D perform the same. Longer standby is the cause of your drain.
Not sure what you mean but my both SG colour units are from FK and that silver one that is performing better is from DN.
I've been thinking about standby causing the drain but like I said when monitoring both in the morning the drain is the same during night. The difference come when FK's have some rest and just when you briefly start to use them they drop a lot while that DN is much more consistent and does not drop usually at all in occasional short use.

Android simply owns Apple when it comes to battery life and power users. It's a real shame, because it keeps loads of people from coming over.

Screen time wasn’t the only usage. I had a lot of calls and other stuff too.

Yeah but when we judge how "good battery life" one very important factor is SOT....Your 3 SOT is kinda low for a high end phone......

Never ceases to amaze me that variability of battery life is blamed on phone or where it is produced.

With the phone radios powering up and down based on reception, turning a corner in your house or work place can dramatically change power consumption.

Along with apps that constantly use GPS radio and then report your location via LTE or WiFi back to their respective masters to snoop your every step.

If you really want to make and report comparisons you will have to create uniform reception conditions and stabilize various radio use in a controlled environment.

When something as simple as deleting Facebook app can double battery life, it’s not the phone that’s the problem.

Sitting supposedly off, screen dark, our phones can be making hundreds of radio connections and GPS checks every hour. Each one consuming battery power.

Both are on a single charge, the longer one is reading books with some web browsing.

The shorter one is browsing and social networking on 4G, outside on full brightness.

Huawei Mate 10 Pro. When bragging about battery life, it better be good.

Here is another test.
My iPhone X (space grey) 2 hours 26 minutes SOT and 45 hours standby, battery from 100% to 47%.
Another iPhone X (silver) 2 hours 32 minutes SOT and 66 hours standby, battery from 100% to 44%.

Seems that results are pretty much the same as my test before and for some reason there is huge difference in practical battery life even both units have 100% battery capacity. Is it possible that there are so big variation in hardware power consumption and battery quality between different factories? Those phones are made in different factories, mine is FK and another is DN. There is also huge difference in build quality between the two units and seems the one made in DN is superior in every way.

Test I made should be pretty accurate since both phones are using the same mobile operator and are in same WiFi network in same environment. Both phones have about the same brightness setting (actually DB unit even has a little higher brightness setting than mine). Also it can be seen in every day use so that while my phone needs to be charged every two days or even less and this another goes three day, even four between the charges. :mad:
I'm already on my second new unit from FK factory (the first one had similar battery life, even very slightly worse) so obviously it is not just faulty unit but there must be some major difference between the two phones.

Also there is no social media apps installed in my phone and I keep nothing running background when I'm not using it. That another one even has some apps running background occasionally.

Can you check how much affect does disabling screen time have on each one?

I guess I could check that soon just in case. So far it has been turned on both phones, so it should provide equal results. Both phones running the same IOS (latest version).

So far thing that I have noticed between the phones in real use is that mine seems to drop 1-2% almost every time it is been used for even short time while that another can go usually couple to few minutes before dropping just 1%. Every other test seem to give pretty equal results, like when I check battery level before going to sleep and then again in the morning (phones not been touched even once during that) or if I run them side by side for example browsing web with Safari for certain amount of time. Difference can be seen only in short random use and in that how often they needs to be charged (mine every 2 days, the other 3 or even 4 days).

I also noticed that SOT counter in battery menu is not very precise. This can be seen with small test by opening up and closing several apps in a row. Each opened app results 1 min of SOT even they were on for no longer than 1-2 seconds (just close them as soon as they have started). That way you can generate 10 minutes of SOT in just 10-20 seconds of real SOT by just opening and closing 10 apps in a row.
