}
then from 20% to 0% is about half an hour of battery life. Is totally uncalibrated and on battery I see what most uses battery is the screen
which it used 2500 mAh in 8 hours of active. And I've noticed from 17% to 10% in 15 minutes consumed 100 mAh more.
Only screen and I don't know why. I have this phone since 107 days ago and I never experienced this. I have other friend with same phone and he's telling me his battery is during from 10 to 20 hours even he's using it to play or using it for apps like Facebook almost the whole day. Apparently my phone has an issue here and it making me anxious.
I also watched a video about and the standard, the screen is consuming no more than 400 mAh.
Any tips with this issue? Hard reset? Downgrade to android 10 MIUI 11? Or should I call warranty and refund/repair?
And also why my screen is consuming a lot of mAh it doesn't makes sense.

[Q] Screen on battery drain?

How much battery does your HTC ONE drain when your screen is on?
Mine drops about 3% every 10 minutes (18% per hour) sitting on the home screen. This means I get only 5 hours (and a bit) screen on time.
Every review out there states 8-9 hours of video playback, but I do not even come close to that.
When the screen is OFF it only drains about 5% for 8 hours (or 0.625% per hour), and this seems very normal to me.
This happens on stock 4.1.2 firmware and on ARHD 12 (4.2.2).
Normally I wouldn't worry about it too much, but the HTC ONE has a non-removable battery so I want to make double sure the battery is ok.
So what say you? Do I experience normal or excessive battery drain with screen on?
Five hours of screen in time is normal for me over an 18 hour day.

How is this battery usage

11.75 hrs off charger, 73% remaining. 29 minutes voice calling, 1hr 3m screen time
Sounds pretty cruddy to me and no way I'd get 8 hrs screen time over 2 days. My screen is on auto but very low.
Bump. I've actually noticed a decent increase by turning off tap to wake
How much of an increase with that turned off, exactly?
I'd standby consumption is down about 30%
Nice. I might try disabling this. Looking for ways to help my battery drain at work (I think it's crappy signal).
I may just get a magnetic charget to use at my desk if nothing helps enough. hehe
wanna know too
My battery has lasted over 6 days now, with about 3.5 hours screen on time, still have 10% left!!! I haven't seen battery life like this before on any phone, simply amazing!

How much screen time
I really don't get how people are getting over 6 hours of on screen time out of this. The battery is really amazing when idle, but when i am using the screen the battery drains like hell. I dont get how people run 3 days on a single charge with 6 hours on screen time, i really dont.

[Q] Sudden battery drain

I've had this phone for about a week and this is the first instance where my phone has gone down to 10% battery in the matter in 8 hours with what I can only describe is light use. I get a few emails, most of the time it sits with the screen off. I checked the battery stats and saw Android OS at 21% usage followed by Cell Standby and Screen.
I am rooted at 5.0.1 but stock and encrypted. Only mods I have done is DPI at 493 and double tap to wake.
Anyone else experienced this before?
So I've been having that issue the past couple days too. I installed a program called BetterBatteryStats.
Yesterday I fired it up after having about half my battery drain in a matter of a few hours.
I saw that my deep sleep was about 3 hours, my awake was 8 or so hours but my screen on was only about 1 hour. Something was keeping my phone from sleeping.
I went threw and uninstalled everything I could think of that had either updated or been added since it started and now it seems to be sleeping again so I'd look at installed apps and updates.

What should I do?
If you have facebook or facebook messenger, uninstall them and retest your battery endurance.
Run Phone Manager.. or else if that dont work. complaint to Huawei and your distributor.
My batterylife varies because I dont have fixed sleeping rythm, sometimes I check out 22-00 and then its about 50% mostly I use the phones for web, browsing, alot of music, and some gaming..
In the other hand finstance in weekends, where I maybe sit up to 02.00 am and sips whisky and listen to music, its about 23%...
It may be that your battery is defect, but I dont know how much you use your phone.
Give it a few days for the power manager to get used to how you use the phone. Any new phone takes a few days to settle on power usage, but more so with Huawei phpones as they have an active power manager that tracks how you use the phone and will adjust power usage appropriately. People always complain about power usage in the first day or so of a new phone.

S20 FE 5G Battery capacity

Hi all!
I've just bought the S20 FE 5g (EU version) and found it unusual that accubattery app reported 4100mah out of the advertised 4500mah. So I drained the phone and charged it to 100% with an USB metter.
So from 0% to 100% this was what I got:

How is your experience?
Battery drains too fast for me!! Drains like 2% within 5 mins after full change 10% after 30mins usually battery drain.

Click to expand...
Click to collapse
losing 2% within minutes of the phone being pulled from the mains is 99% of the time caused by the phone being left on the charger for longer than necessary, for instance overnight. The reason this happens is because the phone stops charging when full and just stays at "100%" even tho its draining and likely is actually 98% despite reading 100%
