T-Mobile and International New App Optimization Update

[Kelly Kearns]

Only Social Media apps I use are Facebook and Twitter. I used the stock email app for a while, but stopped using it, just went back to Gmail.

I'd use GMail if it supported Exchange accounts on all phones (for some reason it doesn't on Samsung devices).

And yup, a friend of mine had issues with his Nexus because of the mail app he was using. He switched to another one and voilá! Better battery life.

Wow! 7 hours of screen on time and still 28% battery life to go!? Need some more info on this:

- What was your screen brightness set to? If auto, were you inside in the dark most of the time?
- What apps were you using mostly to rack up that much screen time?
- I see that you are on WiFi but there is no radio connection besides the basic voice one. For me on Verizon, even if I am connected to WiFi, I still see "4G LTE" next to my WiFi icon. Why is that? Are you not connected to the towers? Turning off the radios would obviously have a big impact on battery drain

Thanks

I was inside, use auto brightness all the time. Basic texting, email, browser, hangouts, work apps, so Facebook, YouTube, Android Central App, etc.

I had just switched on WiFi, I stay on mobile almost always. I don't use WiFi calling. Verizon doesn't seem to shut the LTE off with WiFi on. That will also cause a high standby with WiFi on with Verizon.

I'm connected to the towers even when on WiFi.

I never turn off radios, use airplane mode, etc.

Question. Is there anyway to disable notifications for App Optimization?

We've had this feature in South Korea for awhile, but I keep turning it off because I don't want alerts from the feature telling me it's doing its job.

I don't have notifications about this. You can try Heads Off application from the Play Store, it has blocked things like full battery notifications some carriers use.

There is a free version to test it out and see.

A couple of us have been discussing this feature today and how it works and what it does. We all figured maybe it hibernated apps, similar in how Greenify works or in some ways Doze in Marshmallow works.

We were wrong.

I got someone at Samsung and asked about how this does work, so everyone can know if they want to optimize certain apps or not. I will post a couple of screenshots for optimizing and the choices.

The way this works is by being a power saving feature, per app. That might be fine for some apps, but you might not want it for all. There was a game he told me about, when optimized, makes it black and white instead of color. The game uses a lot of battery, so making it black and white is part of optimizing it. Now he also said it does not make all games black and white.

If you use this and then start having unwanted side effects with an app, then you can turn it off. Think of this as power saving on your phone, but it isn't your entire phone, you can pick the apps to power save.

You have 3 options and nothing is optimizing by default. You might want to go through your apps and check.

Open your battery and you will see it listed under your battery.

I just bought a T-Mobile Note 5 and I was wondering what this was all about. I did a search and lock what I found! Great info!

Very interesting feature.

A couple of things to add on battery life. I was getting 8-10 hours shortly after getting it. I first went through and deleted all apps I wasn't actually using. I'm not sure which app was sucking down battery life, but this improved life to roughly 15 hours (my wife was getting 30+).

Since the update which added this optimization, I am now getting in the 30+ hours region. Part of this is the T-Mobile WiFi phone feature. In the battery graph, I can see, dramatically, the difference between operating on a WiFi connection and operating on the cellular network. I expect this is from T-Mobile having fewer cell towers in the area and needing high power output from the phone.

The screwy part in the middle is where the security update was installed today

Look at the slope when I'm out of the office vs. inside the office. And note that the "inside office" slope is actually more shallow than the expected usage slope. If the phone stays inside WiFi, it can last 30+ hours.
