Is it possible to reset battery remaining time? - Huawei Mate 9 Questions & Answers

Can the battery indicator in settings>battery be reset to default without resetting/restoring the phone to factory defaults ?
When I got the phone the time/hours remaining, was larger than it is now, at a certain procentage of remaining battery. I believe that the software has learned how many hours the battery will last at "my usage", but I guess it will take some time to unlearn if "my usage" gets less and increase the hours of battery time.
I hope it makes sense
Maybe it doesn't work that way at all

Bad Problem with the Battery
i have the TP and the bettery have a big problem it's ended in about 5 hours with no use.
how can i fix it?
is there any program to increase the use or tweak the settings?
from 5 hours no
change the battery
You have either some app running which consumes a huge amount of power (really huge! Even if you use TP as video player with the screen configured to full brightness TPs battery lasts for at least four to five hours). Or your device has got a faulty battery (which would probably be more likely).
Are you by any chance using Wayfinder Navigator gps-software? I found (the hard way) that this software doesn't close the GPS-unit in the phone automatically when you exit the application. Even after a soft-reset the problem persists. This will drain the battery in pretty much 5 hours. The solution is to manually close the GPS-connection in the WF Navigator program settings every time you exit the app (and hope for a fix ASAP). I've already reported this to Wayfinder, and they're working on it.

I was using a GPS related app the other day and the same thing happened to me. Try and find out what hasn't shut down properly...
10X for all
melcul-i think i will send an email to HTC about that
DeepThought-i checked if there is any programs that running but nothing is running acording to X-buttom 35% memory in use.
aBE-One- i am not using that app.just using QuickGPS and Nav N GO IGO8 and they are close.

what aBE-One is saying is that on his phone he had a similar problem, the software was closed but the GPS command remained active thus draining his battery, so your IGO8 might be shut down as software but there is a chance that the GPS hardware is still running in the background for no reason. go into your com manager and turn off GPS and that should resolve the issue

Exactly the same happened to me, after a full charge it took only 5 hours to an almost complete discharge.
I bought TP 1 week ago and it came with radio 1.02.25.17 with no battery issues at all but with the GPS issue -not finding sats-. After upgrading to 1.02.25.28 radio ROM, the GPS now works ok with TomTom, GPS test etc, but the battery now drains dramatically even in standby with no software running and all radios off except phone.
Is possible that the GPS radio stays on even after closing GPS software? In that case, is there any way to manually switch off the GPS module?. In TTN there's no a button to do this.
Mine too..
But i've observed this drain even before upgrating to radio 1.02.25.28
In 40 minutes from 78% to 69% (9%), in stand-by mode (short press power) without any running application!
And I've done 3 or 4 full discharge-full recharge cicles...
LE: No active moderator here? There are plenty of battery problem topics.. why not merge them? It's hard to chose in which one to post... Also, that's not the only case. See GPS related bugs, opera, etc. Too many duplicate topics.
Ok, more info:
I've drained the battery completely till the device turned off then I've left the phone on charging overnight (device turned off).
After about 9-10 hours I've unpluged and turned on the device. Used for 1 hour and 25 minutes in total (about 1 hour for browsing - not downloading, so data transfer was not continously - and the rest for music). With "Auto adjust backlight". The battery level gone from 100% down to 68%, so 32% battery drain in less than a hour and a half!!!
Now, after 4 minutes (device was in standby - eg: short power button press), I wanted to check something and the battery metter was on 66%... so 2% in standy/idle mode in just 4 minutes?!
@l1234 any updates?

That all sounds correct. I can be typing emails/sms with WiFi and phone on (not actually doing anything), drains about 1% per minute.
I read the other day that the percentage indicator is faulty. Some people have reported the battery draining down to 10% in a very short time, but then the meter will stay at 10% for hours before going down to 9%, etc. Has anyone else noticed this? If not, look for it and see if it happens to you. Also, open the power meter in the settings options and verify that it shows the same battery level. I've had that happen to me already where it would say 50% in the title bar but the power options still show 3/4 of the meter!

I have noticed that the battery percentage indicator does this. All in all, my device has better battery life after flashing a custom ROM, keeping screen brightness under half and leaving off bluetooth or wifi if possible. my battery will stay at 100% for hours, but if i soft reset, it drops 10%. other times it will drop right away but stay there. It really does stay at 10% or so though for ages before it drops further.

I was brosing via 3G/HSPDA connection. No WiFi/BT on.
Now, it seems that the drain in standby time is OK (haven't done something special, same processes opened.. maybe just now the battery can be used at its full performance, after some charges/discharges) - BUT when using the device the battery drains quite quickly..
I give you an example.
Battery was 100%. Browsing the internet with IE & Opera for 1 hour. Battery meter was on 75%. So 25% in one hour... tooo much... The display backlight is set to "Auto adjust".
Again, I'm not using Wifi/BT, push e-mail, etc. Just normal browsing (without downloads) with a 3G/HSPDA connection.
I've had my Fuze about a week and I've been testing out many of the available ROMs. I've noticed disturbing trend and want to know if anyone else is seeing this problem, and if so, how can we fix it? It seems like anytime I install a Raphael based ROM, I start to lose battery power at a fast rate - about 10%/hour, maybe even faster. With a cooked ROM based off the ATT Fuze code base, I do not have this problem. I get this even when I install the keyboard fix, etc. and I am doing a hard reset after install to no avail. Any help, input, thoughts or shared experiences welcome.

I am using PROven's latest 1.4 rom and the battery is amazing!!! I loaded it last night, charged it up around 9pm and at 5pm today I am still at 70%!!!
I've noticed this as well. I first go suspicious when after a long flight in airplane mode the battery drained significantly.
No I am in all day meetings this week so I am trying several combination to see what sucks juice and what does not by keeping the radio out of the equation.
So far it seems that RomeOS is a battery suck while NATF is not. This is with the device doing nothing but sitting there with no radio activity.
I've notice that the stock .32 radio on the fuze is the culprit (at least on MY fuze). After I downgraded to the .28 radio the battery life has easily doubled!
@NRGZ28
Which .28 radio do you mean?
1.02.25.28 - Extract Official Shipped Orange ROM ESN 1.90.75.3??
I'm using ROMeOS with 1.02.25.28 radio and I have pretty good battery life on the Fuze. I've also used some other ROMs here and no issues either in regards to battery. Is your data connection on constantly or is it configured to disconnect after X # of mins?

Battery Calibration a Myth ???

Here's the article for lazy people like me...
Today's myth debunking:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
No, it does not.
This file is used to maintain, across reboots, low-level data about the kinds of operations the device and your apps are doing between battery changes. That is, it is solely used to compute the blame for battery usage shown in the "Battery Use" UI in settings.
That is, it has deeply significant things like "app X held a wake lock for 2 minutes" and "the screen was on at 60% brightness for 10 minutes."
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
Deleting it is not going to do anything to make your more device more fantastic and wonderful... well, unless you have some deep hatred for seeing anything shown in the battery usage UI. And anyway, it is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point), so this would be a much easier way to make it go away.

Did somebody try this?
To almost double the Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
I heard it from the same forum.

[Q] About Battery Life

Hi,
I have a question regarding battery life of the OPO. I'm still not sure whether I have a defective battery, or some apps drains my battery like crazy (or both?). I hope you can help me with this.
In the first 2 weeks since I got it, I use my OPO for mid to heavy activities (a lot of Whatsapp, Youtube, streaming music, etc). I always start the day with 100% battery and I thought it was normal to see the battery drops to at least 20% at the end of the day. To be honest, I didn't check the battery stats in Settings even once in this time frame, and due to my heavy usage, once again I thought this was normal.
Until one night I decided to plug the charger earlier than usual, unplug it around 11pm (w/ 100% battery), then I fell asleep. I was shocked the next morning (8am) when I saw the battery has decreased to 65% with no activities whatsoever. I check the battery usage in Settings and then saw Google Play Services (GPservice) at the top of the list with 45% usage, with "keep awake" time almost identical to total time on battery. I did some research and found some advice including 1) denying GPservice abilities to "keep awake" and "wake up" via privacy guard (from this thread http://forum.xda-developers.com/oneplus-one/general/guide-google-play-services-battery-t2832525), 2) turn off location, 3) turn off sync, but none of them seems the solution to my problem. Since then, I always check the battery usage and reset it, to see if GPservice still at the top. Sadly it still there. After I reset the stats, go to sleep directly and check it about 1 hour later, GPservice uses 40% - 60% of the battery usage, draining about 6% battery / hour.
With screen on a few minutes, it easily drops to 5th or 6th place with ~7% usage, with screen and main apps I use on the 1st and 2nd place. When I googled about this using Firefox, that's when I start worrying about something else, the battery itself. With wi-fi and low brightness (less than >20% if I convert it from the slide bar), browsing with Firefox decrease the battery 1% in 2-3 minutes, no or low usage drains 1% in about 5-6 minutes. In contrast, charging increase the battery 1% in 1 minute. Is that normal? IDK, usually bad battery increasing faster when charging and decrease significantly when in use.
Please help, especially about the excessive GPservice battery usage. And if it's possible, I prefer non-root solution for it. Thanks and sorry for my bad English.

Definitely sounds like somethings not right, what apps do you have that access or could potentially access your location? If you're still not having any luck, as a last resort you could try a fresh install of CM11S and install your apps one by one to see if you can determine if any are responsible for sucking battery.
Give the below app a try:

Maps, Google Fit, Google Now, among other things.
CMIIW but I read somewhere that GServicefix does the same like privacy guard, denying some service to keep awake, wake up, etc.
So I installed Gsam and run it about 1 hour. Interestingly in there, Kernel (Android OS) is on the top the % list with 60% usage (mostly phone in idle/sleep). When I switch sorting to Kernel Wakelocks, it shows event0-798 & event2-798 as the top 2 wakelocks with around 7000 wakelocks. I'll update in few hours, thanks.

Hi, sorry for the late reply.
It seems reboot the phone a few times solves the problem. Battery usage now seems normal when idle, even with location & sync turned on.

[Q] Android System using most battery

Hi everyone,
I know battery issues have been discussed a lot, but I see others with on screen times that are far above what I am able to achieve. When I first started using the S7, the battery life was fantastic but I feel that every update has gradually worsened the battery life.
Are there any suggestions to see what is using so much battery? I've attached screenshots that show 23% remaining after less than 2 hours screen on time. I've tried a few battery monitoring apps but they do not provide much more info on "Android System" and "Android OS"...
Thank you!
Wanted to post a new screenshot... battery at 23% at just under 1.5 hours of screen on time (with auto brightness)...
Could try something like GSam battery monitor if you haven't already, seems to be a popular one
https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
Have you cleared the cache from recovery yet?
Obviously last resort would be a factory reset
And if you have upgraded from MM to Nougat and have not factory reset since, that's likely the cause, always advised to reset after a major OS upgrade to prevent things like this happening

Thanks, I will try that battery monitor but I think it will continue to just list "Android System" and "Android OS" rather than the detailed process that is draining so much battery...
I've tried a factory reset after upgrading to Nougat - no difference.
Android System shows only 11% usage on your screens with only 335mAh which is also 11%, so that's not the issue
Screen and Android OS are both using less than 10% each, so at most between those three that's under 30% total battery usage

Good day.
In GSAM you have an option (Enable more stats) in 'more' menu, that gives you the apps that are battery consuming. Try that.
Hi.
I've got a similar experiance on a new S7 bought last week.
It came with Android 7.0 intalled right out of the box, so this should have been a clean install.
My top battery drains are:
Screen: 20% (5h screen on time)
Android OS: 12%
Device standby: 11%
google play services: 10%
android system: 8%
mobile standby: 8%
camera: 7%
I deinstalled several apps, and disabled a lot of automatic syncing and other things like google cast or nearby. The "ususal things" for a better battery life...
I've used a lot of camera, messaging, internet browsing, but none of these apps are on top... it's the "Android OS"...
This is strange, because I never saw this kind of beahaviour on other smartphones.
There's one Samsung app I cannot deactivate: Knox. And it's showing the same percentage of 8% like "Android System" (perhaps because it's a subset of the "system")
I don't want to use Knox, like many other private customers would.
Is there a chance to stop it?
I'm having the same problem. Today was my new low record, 10% battery left with 1h45m SOT.
Wlan has been off, BT off, 4G data on, most used app was Spotify which I used with headphones for about two hours. Before Nougat update I could get 4-5 hrs SOT.
I don't use Facebook or FB Messenger apps, and have actually disabled FB and a lot of other junk with Package Disabler Pro. Using PDP doesn't really have much effect on my battery life.
Is it safe to clear the cache if I'm not planning to do (yet another) factory reset?

System apps aren't measured individually for performance reasons, so you're right, it's a subset of "System" and not necessarily using that amount of battery. Knox is a security feature. You cannot disable it without modifying the firmware and voiding the warranty. It genuinely doesn't do much if you don't use it though (but might get annoying if you're rooted).
