Personal experience over the Note 5. this thing kills battery life expectancies.

The Note 5 with:

BT ON Connected to huawei watch

GPS off

No Autosync

All apps killed

No calls

15 texts per day max

Packages disabled

1-2 hours of screen use tops

I Got maximum 13 hours. I get up every day at 8am and by 7-745 its nearly dead doing next to nothing. Android will not sleep and samsung refuses to accept its their software. My Mate 9, buds Moto Z play both on tmobile never have issues. he gets 8-9 hours screen time i get 8-9 hours screen time charge once every 2-3 days.

My Settings are EXACTLY the same with the exception of:

BT off when not using my Sony M1000x headphones.

300+ textsPer day.

No calls

Checking FB via Metal for FB

Email in Gmail 5-6 times a day

Camaro Forums via chrome browser

Instagram

Spotify + many more apps

And i never have issues. Granted i exchanged it because the B156/157 idk which one ruined battery. i have a B138 fw now and it works flawlessly. Its pathetic samsunbg phones barely make it through the day even when NOT used. Im dropping samsung and sprint very soon.

If your main consideration is battery life I do not think you will be disappointed.

But for what it is worth I will tell you the points I do not like about the Mate 9.

The vibration is very weak.

The notification light is tiny and almost invisible except in the dark.

The GPS is poor and no good for sports use.

There are various problems with notifications and some email apps don't work properly.

All these problems are discussed in this forum.
[Huawei Mate 9 Questions & Answers] applehater00:
Oh.

The GPS worries me - I use GPS a lot for visiting clients, is it not accurate or good enough?

And will the normal gmail app work ok?
[Huawei Mate 9 Questions & Answers] applehater00:
Ok thanks

Strange though because people are saying the B156 one is fine. Opposite to your experience.

Maybe the battery just goes crazy and dies at some point?

whatever the reason is i bet every user have diff usage n diff type of apps running in their phone,but all i can say this phone can last me from 7.30 til 11.30pm with everything on(except for BT n NFC) and most of the time i m on 4g,i can get 6-7 hours of SOT with whatsapp,email,telegram heavy chrome browsing,youtubing,xda-ing,some gaming(coc,skyforce).and when i wanted to go tl bed at 11.30 it still have 20% left
[Huawei Mate 9 Questions & Answers] RR-99:
The GPS is fine for ordinary driving use, and it gets a fix very quickly. But there are some serious issues that Huawei aren't mending.

Read through this thread for details. https://xdaforums.com/mate-9/help/gps-problems-stats-reports-t3508213

Sorry I can't help you with gmail as I don't use it on this phone.
[Huawei Mate 9 Questions & Answers] ante0:
Right now I have 89% left, 10 hours active, 33 mins SOT. I think I got 7h SOT yesterday and still 50% left.

Compared to my Note 4 which barely lasts 12 hours, and that's idle time.
[Huawei Mate 9 Questions & Answers] applehater00:
Ah i see thanks.

Thats disappointing. I may wish ti get back into cycling and if it cant track my ride accurately it sounds like a dud. How ridiculous! Just as i was about to buy one another problem pops up.

I wonder if huawei just aren't ready for making phones...!
[Huawei Mate 9 Questions & Answers] RR-99:
It's a shame, yes. There are of course many good things about the Mate 9. They just let it down on a few things.

I've owned the note 4 for 2 years before my mate 9... id be toast on the note by 3 pm everyday... i easly make it till 6 pm with the mate. i use my phone often throughout the day.... the note 4 was a great phone. the mate is by far the best all-round phone Ive ever used.

battery is good

i get the phone if u be very heavy user it'll last for 11 hours with Facebook while if u not install FB u'll get 10 hours more

With the exception of B138 I've been getting 10h+ SOT since day 1. Owned the device since late November. Happy days.
[Huawei Mate 9 Questions & Answers] Paz9:
ive disabled all non-essential services via disable services PM me and i can send you the file.txt you can restore in disable services, ive also disabled alot of system non essential applications (BEWARE DO NOT DISABLE PHONE MANAGER- it will break the phone and make you lose your mind lol (disabling the service is fun, you just wont be able to see specific things that it uses to monitor, i.e data usage in settings) , i can also provide a list of disabled apks)

i also have a init.d script to run - disables journaling, sets background applications to use less CPU cores, mark all mounts as non rotational and disable iostats, disable debugging and hungtask scanning (disabling hungtask scanning can be a bad thing, but id rather not have my system scan unnecessarily for hungtasks), fstrim run on every boot, renamed some /system/bin files to prevent any unnecessary logging or debugging.

in gsam my kernel reports using alot less after doing all of this. hwcamvfgsvr is actually one thing i cant fix to use less power (its related to the camera, so as soon as the camera runs this service starts to run) actually uses more power than i thought it would haha.

last night on low brightness i managed to get 1 hour an 30 minutes SOT then sleep time of 10 hours and only lose 11-12% battery (ive also got naptime on my phone).

B156.

Check if you don't have an "eternally syncing" Google process. It happened to me with the Google Calendar sync when I first set it up (would fail to sync and reattempt over and over again).

Settings > Accounts > Google

It's not uncommon. Main China based companies have issues with GPS outside of China. This is due to security concerns and copyrights.
[Huawei Mate 9 Questions & Answers] 5[Strogino]:
But not in this case. GPS works great if you're driving (when phone is in static), very fast start and lock satellitess, GPS/Glonass/Beidou support (not sure about Galileo), but there are some troubles when you are cycling or hiking, when phone moves and jumps with your body. Think, Huawei didn't test this case or was too lazy.

I also have Nubia Z9 Max (brand ZTE) phone and it has not​ any GPS problems.

P.s. According to your posts, you are always beware of Chinese brands (especially Huawei). I could agree that it is right personal opinion and brands are not fair gathering user's data. But Mate 9 approved by FCC and you can search for testing results.
[Huawei Mate 9 Questions & Answers] RR-99:
I do not think that is right.

All the basic satellite transmissions are free to use.

There are more accurate parameters that require licensing, but they are for military or business use and require special receivers. .

Ordinary smartphones do not use the advanced parameters and it should not matter where they are made.
[Huawei Mate 9 Questions & Answers] zelendel:
Being approved by the FCC is nothing really. China based devices have always had limited access to the satilites in the US. This comes from the constant bans on them due to security reasons. Heck this OEM was banned from the US up until recently and has even been banned in India for the same security issues. They are even still on the restricted list for military and government use.

Yes I warn about devices from China. This comes from knowledge and experience that most new smartphone users are unaware of. Stuff that is common knowledge for those that have been in the mobile development world for more then a few years.

You are not looking at it right. All cell phones are considered business devices due to the business that licenses their use,. Really you think they are all free to use? Go ahead and try to get access to one of them. It is not a a big leap knowing that even the police need a warrant to get that type of info.
[Huawei Mate 9 Questions & Answers] cabtouch:
M9 has the best battery life of all phones I have had till now. With medium usage, some apps disabled but online syncing 3 email accounts, Whatssapp and FB, I still have more than 50% at the end of each day.
[Huawei Mate 9 Questions & Answers] RR-99:
What do you mean by "access"? The transmissions from the satellites are a one-way broadcast that anyone can receive if they have the right equipment. You do not have to get permission from the satellite operators to receive the basic open signals. The format of GNSS signals is an open standard and GPS, Glonass, Galileo and Beidou all use it. It is only the advanced, encrypted modes that need a license from the satellite operator.

If a smartphone manufacturer wants to sell his products in a country he needs to get need type approval from the telecomms administration of the country, like the FCC in the US. This is basically to make sure that it meets certain quality standards and does not cause interference to other services. This includes the GNSS receiver in exactly the same way as the phone transmitter and receiver, the Bluetooth and the WiFi. There is no special security issue for the GNSS.

If the equipment is built to a satisfactory standard to pass the type approval it does not matter what country it was made in - unless of course there are trade restrictions for political reasons.

In addition to the type approval, most countries have a general law that radio transmitters and receivers must be licensed by the user. But in most developed countries this is in the form of a free "class" license for equipment like smartphones, if they are type approved. Most smartphone users will not even be aware that this license exists, and they don't need to.
[Huawei Mate 9 Questions & Answers] zelendel:
That maybe how it works in your country but not here. A perfect example is that a few times a week no gps works in my town as the military has them all jammed. The FCC only covers the basics.

There are also security concerns that take effect. Like this OEM itself. For a long time you were not allowed to even own the device if you worked for the government. While they are only now on the restricted list it still limits the places it can be taken.

Do a little research and you will see that devices from China are nototrious for working very spotty with gps.

I found this odd myself until it was explained to me by the tech at the nuclear missile silo that is in my town.

You have to understand that China is on just about everyones scetchy list. Like I said this OEM has been flat out banned in alot of countries over the years due to security.

Another example is xiaomi devices used to not be able to connect to US gps at all. The same is in reverse.
[Huawei Mate 9 Questions & Answers] applehater00:
I don't buy that I'm sorry. Korea is safe but China isn't? Where's the cutoff?

I'm not reading any reports of any problems with the Mate 9 and GPS anywhere, including the US, just how it handles certain sports apps losing fix periodically thus making it not as useful for those apps. It doesn't add up to me. "Some bloke down working in a nuclear silo" doesn't sounds like an authority. And blocking "all GPS" as you say temporarily due to military safety would affect as you say "all GPS" at that time, not occasional sports apps on Chinese phones. Any problems Chinese have or have had historically are likely due to poor implementation rather than a bloke down a nuclear silo blocking Chinese phones or Chinese phones not being able to get the same GPS data a Korean phones.

Sounds awfully convenient for the likes of US companies to be spreading around rumours in the US that "Chinese stuff won't work here" ;)
[Huawei Mate 9 Questions & Answers] Kirkland301:
I've only had my Mate 9 a day and a half now but already I am massively impressed at the battery life compared to my old Xperia Z5. Time will be the real tell though.
[Huawei Mate 9 Questions & Answers] RR-99:
applehater00 has already answered you very well, so I'll only add a couple of points.

You again said "access" satellites. GNSS receivers do

not

"access" satellites. They only

receive

the broadcast signals. The satellite system doesn't know if the signals are being received or not. It doesn't matter if the receiver is made in a factory in the US, Europe, China or by a radio ham in his garage. All receivers receive the same open signals, and unless they have the encryption keys they cannot get the high precision fix.

Of course the military in any country can and do jam the signals at various places and at various times. That's a given. But they cannot selectively jam only one make of receiver. If they jam the signals they are lost to every receiver within range.

And it's also a given that military and commercial companies ban all sorts of equipment from their establishments for security reasons. Many ban smartphones, and when they do it is a ban on every make of smartphone, not just Chinese ones. The ban is usually because they can be used to steal secrets, not because they can receive GNSS signals - everyone knows the location of the place already!

Edit: If you want to continue this discussion I'm very happy to do so, but I think it would be best in the thread that is already running about the Mate 9's known GPS faults, rather than this one about battery life.

I don't own one yet. Have been holding off for GPS to get better (sounds like it is). Also debating waiting for 1+5 or Mate 10.

But, I can tell you that battery life on the V20 is not great. I had one for about 30 days. Sent it back because of poor BT performance. I did really like the phone. Battery was not as good as my current Note 4.
[Huawei Mate 9 Questions & Answers] NikiFue:
The battery of my mate 9 is really NOT GOOD. I never get through the day with it. Between 20:00 and 21 :00 the phone needs to be recharged. And i never use location services or any power hungry apps.
[Huawei Mate 9 Questions & Answers] combatuser:
Battery life these days are quite phenomenal for me. Didn't even run power saving mode.

[Huawei Mate 9 Questions & Answers] Sammath:
Pretty good for me, charge it once every 2 days.

However I do have to say that 156 is a bit worse than previous firmwares for me. B126 was the best for me imo.
[Huawei Mate 9 Questions & Answers] schlockmaster:
I have been buying and selling Chinese Hardware for 10 years. I think the issue this poster has is that Huawei is owned by the Chinese Government and therefore questionable in how it operates. GPS is a one way signal that beams down from a Satellite to triangulate your location. What strategic value does that have unless your the Paranoid Military that doesn't want people to have co-ordinates for a Missile Silo that should not exist? We are speaking about hardware functionality and software on this forum. The reality is that I would be more concerned about Back Doors built into Android Software on ANY phone which could be used to relay information to people who would use it for unscrupulous purposes. Even Apple wouldn't assist the U.S. Government to hack the Terrorists Iphone and that was a very National Security matter. I'm concerned about my Online Banking, transfer of Credit Card information, and anything someone could capture and then sell to criminals and exploit my Identity. Identity theft is the major concern for any Smartphone user.

IN the meantime I have owned countless Huawei phones and the quality and design is excellent. Very reliable. One things for sure throughout the entire time I have owned any Chinese phone they haven't exploded or caught fire like the Beloved Samsung Note 7. I've also read that their new Galaxy S8 has a very similar design internally to the Note 7 and that they are using the same battery supplier.

[Huawei Mate 9 Questions & Answers] CandyAndy:
Mate 9 Pro here. Been using it soon 6 months and as a phone junkie I often have changed my phone after 6 months. However this time I still see no need at all to change to Galaxy S8 for example. And the biggest reason is the battery life. Mate 9 Pro is the first phone after Xperia Z3 which has made me totally happy with the battery life. I am not willing to compromise the battery anymore even if S8 Plus otherwise looks sleek.

I used Kenobi vibeX3 before switch to Mate9 but,I feel the real live both battery different maybe 8% more since vibeX3 will be 3500,while mate 4000.

But the mate win on charging speed, although Kenobi also provide quick charging 2.both speed has huge gap.

But lenovo win the sound on phone jack output and speakers.I just don't like the mate9 sound too unbalanced and noisy.
[Huawei Mate 9 Questions & Answers] combatuser:
I think the biggest factor to get good battery life is to have good 4G/3G signal and low brightness settings. I also turned off Bluetooth and wifi scanning.

For the close app upon screen off setting, I closed almost everything except chat apps.

I don't clear recent app, neither do I go to phone manager and optimize everyday. I don't restart the phone as well.

That 12hr SOT with 20% battery life less is mostly browsing forums using brave browser and Twitter. Also browsed Instagram, play around 1 hour COC and watch 2 hr of kdrama.

For brightness settings, I manually adjust it. Most of the time it is set at around 20%. If under sunlight, as bright as 40%

I think marathon usage helps as well :cool:
