What I've noticed on my current phone (which ended up not being a P9) is that Marshmallow and power settings make these numbers vary immensely. I end up having tons of news agencies and newspapers apps installed that push notifications but the phone will put them into power saving mode if I don't touch them for 3 days or if I don't specifically tell it not to do so. So if something important happens on a particular day and I'm trying to fact check something, I end up taking a lot of them out of hibernation and that might mean 1 or 1.5 h less of SOT for the next few days. Stand-by drain during the night might also double.

Man, I'm getting some shocking battery life here... 2.5 hours SOT, and the phone is discharging quicker than it is charging (dropped to 2% typing this)

Is there any known remedies for terrible battery life? I have already formatted my external sd with no luck, and was previously on a 161 firmware which wasn't the worst id tried (3hrs sot from memory). But I am using c900b170 (after trying to update to a 166 firmware) and it is just terrible... Barely a day... :confused:

How are you getting so good battery life? My Huawei P9 gets to 25% after approx. 2 hours SOT. I have messenger running, Facebook app installed and Instagram. On the "Software" tab on the consumption list Android System uses the most battery.
[Huawei P9 Guides, News, & Discussion] Brontok:
smart mode..using 2g/wifi all the time, rise of the kings, viber, fb messenger, reddit, ebay, alliexpress, xda app, and others.. so far so good. I have noticed that I loose battery more than normal if I have for example 25% and than I go outside and use my phone while it`s cold ( it was around -11 celzius today ). It starts loosing around 5% in 5 minutes, if I`m constantly using it. No idea if its normal or not. Once I get inside of a warm room things go back to normal. :)

I have 6-7 hours of SOT if wi-fi is switched on 24 hours per day. Or 8 hours of SOT if wi-fi is switched off. I used Performance mode, only fb messenger and WhatsApp are protected in ignore optimisation and battery optimisation.

I highly recommend you to install wakelock detector lite, do exactly as what it said to gain permission without root. At the mean time, goto setting and disable auto-syn account underneath Accounts, which will partially solve the android system battery drain. Disable all of your apps apart from Google map from accessing the location can kill the infamous NLP wake lock too. Good luck.
[Huawei P9 Guides, News, & Discussion] .rc:
I don't have much problem with Screen-On Time of P9. I find 3.5-4.5 hours of SoT quite acceptable.

However, I do have problem with how much P9 consumes battery during standby.

I just got my P9 and have noticed that it has used quite a lot of battery, even in Doze mode.

As you can see, P9 entered Doze mode at 22:40 and existed Doze mode at 11:20 on the next day.

During that standby period, P9 used 9% of battery. (I marked standby period with 2 red bars.)

This is very concerning, considering my old phone, Xperia Z3 (Lollipop 5.1.1), usually consumes around 1-2% for the whole night.

I already have had Power Nap and ForceDoze installed, which clearly do not work since the phone awoke several times during the night.

I have checked battery stat in Settings, but P9 does not report any app has been using battery, so I guess it must be some System components that consumed battery.

Does high battery usage during standby a normal behaviour for P9?

Is there anything I could do to make P9 consumes less battery during standby?
[Huawei P9 Guides, News, & Discussion] Brontok:
Hey .rc. You could try and select smart mode in battery setting. Also disable accounts auto sync and set protected apps only to few of those apps that you really need. All of these settings (except auto sync which can be found under settings-accounts) can be found in settings-advanced settings-battery manager. And please let me know what happens when you go down to 25%..Do you loose the remaining 25% in the usual way, or the percentage goes down faster than from 100 to 25%, as it is the case with my phone :) . Thanks.
[Huawei P9 Guides, News, & Discussion] kzh11411:
For me, the battery consumption reduces remarkably when the wi-fi is off. 3% of battery for around 8 hours of standby. Xperia Z3 is well known for its long battery life (see gsmarena), it might not be wise to compare both of them. Anyway I suspect that the android system might be corrupted in someway, interestingly this problem is present in almost every huawei phone (e.g. high android system drain). I would like to do further investigation but I do not want to root my phone yet haha as it is still under warranty coverage.

With wakelock detector lite I discover that C2CMhandlerthread contributes to a significant amount of wakelock. Disabling Google account sync I am able to cut it into half, and resulting in an observable battery saving. I am still trying different way to cut down the wakelock without rooting. Any advice here will be welcome!
[Huawei P9 Guides, News, & Discussion] Brontok:
maybe try installing accubattery. It tells you how much time the phone has spent in deep sleep mode and it also tells you the exact percentage spent by each app. For me android system (google play services) takes around 12% of battery during each full charge.
[Huawei P9 Guides, News, & Discussion] carlese:
Where is smart mode in settings? I am on nougat b361 and can't find it..
[Huawei P9 Guides, News, & Discussion] kzh11411:
Can I know which version of firmware you are using? 12% of android system usage is very impressive, my android system usage is stubbornly high at 30%. Would you mind to share your setting too (e.g. protected app, smart mode, wi-fi)?

Anyway I think it is normal for battery to discharge quickly in such a cold weather. When I was using my camera it can only take half as much pictures before it ran out of battery, same goes to other devices too. The optimum temperature for battery to function normally should be above 5 degree Celsius.

Sure, Im on stock MM B182. Wifi is turned on all the time. Location services, nfc, auto account sync are all off. Using smart mode, and 2g network, with only few protected apps, such as viber, weather, nova launcher, tesla unread, dimmer.

I know that batteries drain faster when its cold but my gf's galaxy j5 doesnt behave the same.Plus my outside draining is ok if I have more than aprox. 30% battery left. Thats why I asked. And not a single phone I had in the past drained faster when they were at around 25% during a cold weather. Maybe I just didnt pay attention that much :)

[MENTION=5299036]Brontok[/MENTION]

A TechRadar's video shows the same behaviour as you described.

The 1st 90 min, it shows P9's battery decreased by 37%, that's ~146 secs for 1%.

Then, the 2nd 90 mins: 39% decrease, ~138 secs for 1%

The last 24% depleted in 37 mins, ~92.5 secs for 1%

The lower battery percentage, the faster it will discharge.

This also happens with Huawei Mate 9 in the video.

The 1st 90 mins, Mate 9 used 29% of battery.

The 2nd 90 mins, it used 24%.

The 3rd 90 mins, it used 40%!

iPhone, on the other hand, discharged at the similar rate through out the test.

Hi everyone!

Battery life is a fascinating topic for me, and for many others ... I'm always reading and researching about it.

I recommend you this app, https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector.noroot,

And please, read through the instructions: http://goo.gl/7WgGz

I use this little app to identify main battery drainers and spot anomalies :)
[Huawei P9 Guides, News, & Discussion] nostromo76:
Hello friends, I want to share with you my most recent finding about battery draining.

I'm on EVA-L19c185b361 (Nougat), so far, I found out this:

+ Bluetooth drains lots of battery (much more compared to MM)

+ LTE / 4g drains a little more battery than MM

+ WhatsApp always drains lots of battery, BUT, "web-client" generates a lot of CPU Wakelocks (I don't know if this behaviour existed on MM)

+ Facebook, Google+, etc. This kind of apps (which sincs frequently) always drains battery
[Huawei P9 Guides, News, & Discussion] .rc:
Yeah, even after I did everything listed in this battery guide thread, my standby discharge is still ~1% per hour when battery is around 20% or less.

After days of trying to make P9 consumes less battery, I gave up, and accepted the fact that P9 will always have terrible standby time.

And I bought extra powerbank. It's much easier this way.

EDIT:

After reviewing information from GSam Battery Monitor, I concluded that radio chipset used in P9 might not be energy efficient. And it is most likely the main cause of P9 battery drain during stand-by.

As you can see from my screenshot, it had been 25 hours and 12 minutes since I unplugged my phone.

I only received a call for 1 min and read some texts (used the screen for 7 and a half min).

Other than those, my phone was put stationary on a table for ~25 hours.

Since last unplugged (100% charged), my P9 had consumed 7% of battery.

And 72% of battery consumed was caused by Phone Radio. That is equal to 5.04% out of 7%.

So, if stand-by battery drain really caused by inefficient radio chip-set, then we, as users, probably can do nothing about it beside carrying an emergency powerbank around.

One thing to keep in mind though, this information is from when p9 was fully charged.

In my experience, P9 appears to discharge very slowly when there is a lot of battery left.

That is why it shows P9 only use 7% of battery for 25 hours stand-by.

However, when battery reach ~20%, it will deplete at a much much faster rate.

In my case, P9 usually consume 1% per hour during stand-by when battery is ~20% or less.

But, if you sleep the phone with the rear button, the fingerprint reader will work to unlock the phone.
